Study Links Cat Litter Box to Increased Suicide Risk

A common parasite that can lurk in the cat litter box may cause undetected brain changes in women that make them more prone to suicide, according to an international study.

Scientists have long known that pregnant women infected with the toxoplasma gondii parasite -- spread through cat feces, undercooked meat or unwashed vegetables -- could risk still birth or brain damage if transmitted to an unborn infant.

But a new study of more than 45,000 women in Denmark shows changes in their own brains after being infected by the common parasite.

The study, authored by University of Maryland School of Medicine psychiatrist and suicide neuroimmunology expert Dr. Teodor T. Postolache, was published online today in the Archives of General Psychiatry.

The study found that women infected with T. gondii were one and a half times more likely to attempt suicide than those who were not infected. As the level of antibodies in the blood rose, so did the suicide risk. The relative risk was even higher for violent suicide attempts.

"We can't say with certainty that T. gondii caused the women to try to kill themselves, but we did find a predictive association between the infection and suicide attempts later in life that warrants additional studies," said Postolache, who is director of the university's Mood and Anxiety Program and is a senior consultant on suicide prevention.

"There is still a lot we don't know," he told ABCNews.com. "We need a larger cohort and need a better understanding of the vulnerabilities that certain people have to the parasite."

Suicide is a global public health problem. An estimated 10 million attempt suicide and 1 million are successful, according to Postlache's work.

More than 60 million men, women, and children in the United States carry the toxoplasma parasite, according to the Centers for Disease Control and Prevention, but very few have symptoms.

Toxoplasmosis is considered one of the "neglected parasitic infections," a group of five parasitic diseases that have been targeted by CDC for public health action.

About one-third of the world is exposed to T. gondii, and most never experience symptoms and therefore don't know they have been infected. When humans ingest the parasite, the organism spreads from the intestine to the muscles and the brain.

Previous research on rodents shows that the parasite can reside in multiple brain structures, including the amygdala and the prefrontal cortex, which are responsible for emotional and behavioral regulation.

Rat Study Showed Parasite Changes the Brain
A 2011 study on rats infected by the parasite showed that their fear of cats disappeared. Instead, the parts of their brains associated with sexual arousal were activated. Researchers theorized that the mind-manipulating T. gondii ensures that the parasite will reach and reproduce in the gut of a cat, which it depends upon for its survival.

"The parasite does actually alter the brain of its host," Stanford University study co-author Patrick House told ABCNews.com last year. "The fact that a parasite can get into an organism, target its brain, stay there without killing the host and alter the circuitry of the brain -- we've seen this is insects and fungi, but it's the first time we've seen it in a mammalian host."

It was this and other research that led Postolache to investigate the relationship between the parasite and biological changes in the brain that might lead to suicide. He was also intrigued by studies on allergies and research that showed a connection between toxoplasmosis and schizophrenia.

"I was interested in the neuron aspects of suicide and intrigued by low-grade activation in patients who attempted suicide, as well as victims," he said. "Other studies had looked at the brain and suicide risk and impulsivity. The next question was, what could be the triggers that perpetuate this level of heightened activation in the brain?"

Postolache collaborated with Danish, German and Swedish researchers, using the Danish Cause of Death Register, which logs the causes of all deaths, including suicide. The Danish National Hospital Register was also a source of medical histories on those subjects.

They analyzed data from women who gave birth between 1992 and 1995 and whose babies were screened for T. gondii antibodies. It takes three months for antibodies to develop in babies, so when they were present, it meant their mothers had been infected.

The scientists then cross-checked the death registry to see if these women later killed themselves. They used psychiatric records to rule out women with histories of mental illness.

Postolache said there were limitations to the study and further research is needed, particularly with a larger subject group.

Dr. J. John Mann, a psychiatrist from Columbia University, said Postolache's research mirrors his work in the field of suicidal behavior.

"The relationship of the brain to the immune system is more complex than it may appear," said Mann. "The brain regulates the stress response system, which impacts the immune response."

Scientists already know that steroids like cortisone can affect the immune response. Some antibodies whose goal is to kill off cancer can also affect the brain. Oftentimes the first symptom of pancreatic cancer is depression, he said.

Research also shows that streptococcus bacteria can trigger obsessive-compulsive disorder (OCD) in some children. Sydenham's chorea, the loss of motor control that can occur after acute rheumatic fever, may also be an immune response affecting the brain, according to Mann.

Maryland researcher Postolache suspects that some individuals have a predisposition to these neurological changes.

He speculates that the parasite may disrupt neurological pathways in those who are vulnerable, so that projections of fear and depression from the amygdala are not tempered or controlled by the "braking" function of the prefrontal cortex.

But, Postolache warns that even if a direct cause were found, no antibiotics for T. gondii yet exist and it could be a decade before effective vaccines or other agents that might stop the neurological damage are developed.

Right now, the most effective weapon against T. gondii is education about handwashing, the proper cooking of food, and not using a knife exposed to raw meat on cooked meat.

He also cautions against trendy food production techniques that let animals roam free. "The risk of infection could go up," he said, "and increase the rate of toxoplasmosis."

Brian Kearney was an angry teenager.

"There were lots of holes in my bedroom wall," said 21-year-old Kearney, recalling the "superhuman strength" that sent his VCR clear across the room. "I would say I was a little on edge."

For Kearney, who also struggled with an eating disorder in his teens, anger was a way release the pressure of high school.

"I didn't develop appropriate coping mechanisms," Kearney said.

Nearly two-thirds of American teenagers admit to having "anger attacks" that that involve destroying property, threatening or engaging in violence, a new study found. And one in 12 has intermittent explosive disorder, characterized by chronic, uncontrollable fits of rage.

"It's an enormous problem that mental health professionals have not taken seriously," said Ronald Kessler, a psychiatric epidemiologist at Harvard Medical School in Boston and lead author of the study, published Monday in the journal Archives of General Psychiatry. "I think it's clear from this study that needs to change."

"Without a really good reason, people all of a sudden feel very fearful, or very angry, and do something excessive," he said. "It's either fight or flight."

For Kearney, one wrong look could trigger a "vicious" reaction.

"I can't explain how I felt when I was in one of those fits of rage," he said. "It's almost like I would black out."

Kessler said Kearney's situation is too common to ignore.

"One in 12 kids has this problem. And people very often continue to have this problem into adulthood, affecting their education, jobs and marriages," he said. "Not to mention the criminal implications."

Although IED is listed in the American Psychiatric Association's Diagnostic and Statistical Manual, its cause – and how best to treat it – remain unknown.

"It bears studying, because what we currently know remains speculative," said Dr. Bela Sood, chair of child and adolescent psychiatry at VCU Medical Center in Richmond, Va.

Sood said IED can be hard for patients – and their parents – to handle.

"During an episode, a person goes from zero to 60," she said. "Afterward they often feel remorseful, but the deed is done."

Kearney said he would apologize to his parents after an attack but admitted the anger took a heavy toll.

"It definitely affected our relationship," he said. "But in the end I'm closer to them than I ever was."

Kearney, now a junior at Rowan University in Glassboro, N.J., patched up his relationships – and the holes in his wall – and left his troubled teenage years behind. He credits talk therapy for his victory over anger, as well as Xanax that helps quell his anxiety.

"Everything I've gone through has shaped me into the person I am today," he said. "And I think I'm a pretty good person."

It is difficult to accurately capture the full effect of marginalization, discrimination, and stigmatization on the mental health of an individual or minority group. LGBT persons "are subject to unique social stressors such as prejudice, stigmatization, and antigay violence that may precipitate mental distress, mental disorders, suicidal ideation, and self-harm."[6] Matthews et al[20] studied the role of sexual orientation in predicting depressive distress in a sample of women. Their sample (N 5 829) showed "51% of lesbians and 38% of heterosexual women reported seriously considering suicide at some point in the past."[20] Also, "more than twice as many lesbians as heterosexual women in this age group (15–19) reported suicide attempts."[20]

Although research is limited, LGBT youth may also be at increased risk for suicide attempts compared to their heterosexual counterparts. Marshal et al[21] found that there is a higher rate of suicidality in sexual minority youth compared with heterosexual youth. However, in the study of LGBT youth by Mutanski et al,[22] there were similar rates of suicidality compared with youth of the same geographical areas. They also noted that mental health disorders were higher among the LGBT youth group compared with national data samples but similar when compared with ethnic/minority urban youth samples. Haas et al[23] said, "Over the last 2 decades, an increasing body of empirical research in the US and other countries has pointed to significantly elevated suicide risk among LGBT compared to heterosexual people."

Although there is limited research describing reasons for increased risk in the WSW population, it may be that many mental health issues are associated with the consequences of being a WSW living in a "heterosexual-oriented society."[7] "Heteronormativity denotes how the social life of Western culture is constructed on the assumption that all people are heterosexual, assuming the heterosexual nuclear family
norm to be natural and universal, and thereby making homosexuality socially invisible and second class."[13] It is important to understand that marginality of any kind can be a risk factor for mental health issues. Lehavot and Simoni[24] suggest screening (and referring as needed) for minority stress and the presence/absence of "coping resources" among sexual minority women.

Substance Abuse

Spinks et al[5] said, "Accurate estimates of the prevalence of substance abuse in lesbians are not available due to the marginalization and hidden nature of the population."[5] The rate of alcohol abuse in WSW is unclear and data are conflicting. Dean et al[1] identify that early studies on the gay and lesbian population recruited subjects in bars "which, not surprisingly, showed higher rates of heavy alcohol and drug use than the general population."

Many reports discussed by Roberts[16] indicate that there is more alcohol use in the lesbian community. "Data from the Women's Health Initiative study and other, smaller studies indicate that tobacco use is higher among lesbians than among the general female population."[6] This finding is in contrast with the Dibble study mentioned above. Roberts[16] said, "Reviews have concluded that smoking rates for adolescent and adult lesbians are higher than their national comparison groups, with adolescents being highest for both groups."

Blosnich and Horn[25] examined discrimination/violence and associated smoking among young adults and found that sexual minorities were more likely to experience discrimination and violence and are twice as likely to smoke when compared with heterosexuals in the same age group. It appears that there may be increased substance abuse among WSW in comparison to heterosexual women, but this, too, needs further research. Many factors may put WSW at higher risk for substance abuse or mental health issues, including social stigma, societal pressures, internalized homophobia, the "coming out" process, and discrimination.[5,6,16]

STDs and Reproductive Health/Services

Women who describe themselves as having same sex orientation may identify themselves as lesbian. However, sexual behavior is not the same as sexual orientation, and these should not be confused.[4] Obtaining an accurate sexual history is important to identify risk factors for STDs and safe sex practices. Sex practices of WSW vary widely and the most important thing a provider can do is refrain from making assumptions.

The risk for STD transmission in WSW changes based on sexual practices and the STD organism.[4] Little is known about transmission of STDs between 2 women. "Transmission of some STDs between women is known to occur; for other STDs, transmission between women is possible in theory but has not been proven."[6] Mravcak[6] provides a table in her article showing known transmission of STDs between women to include herpes simplex, genital warts associated with HPV, and trichomoniasis. Included in the table is the description of theoretical STD transmission between WSW: chlamydia, gonorrhea, syphilis, hepatitis B, and HIV.[6] Bacterial vaginosis, while not an STD, is commonly found in the WSW and their female partners[6,16] and is believed to be transmitted between women.[16]

As identified earlier in this article, most WSW have a history of male sexual partners. This fact increases STD risk for these women and their partners. However, Mravcak[6] said, "Lesbians are less likely than bisexual or heterosexual women to be tested regularly for STDs."[6] Many WSW may not believe that they are at risk for acquiring STDs and may even delay treatment when symptoms arise.[4] In addition, NPs may have inaccurate information about the risks of STDs for WSW and assume that they are not engaging in heterosexual intercourse.[4] This assumption may result in the provider choosing to omit needed routine screening for these patients.[4]

NPs need to teach safe sex practices for WSW. Some recommendations given by Mravcak[6] are to avoid contact with any visible genital lesions, cover sex toys that penetrate more than one person's vagina or anus with a new condom for each person, use a barrier during oral sex, and use latex or vinyl gloves and lubricant for any manual sex that might cause bleeding. The Centers for Disease Control and Prevention[26] (CDC) determined, "No barrier methods for use during oral sex have been evaluated as effective by the Food and Drug Administration. However, natural rubber latex sheets, dental dams, condoms that have been cut and spread open, or plastic wrap may offer some protection from contact with body fluids during oral sex and thus may reduce the possibility of HIV transmission."

The CDC[26] also suggests the importance of knowing a partner's HIV status since there is a potential for HIV transmission through menstrual blood. For WSW at this time, oral sex does not require barrier methods if performed with a monogamous partner whose HIV status is negative and has no lesions or other risk factors.[26] Jeanne Marrazzo, MD, MPH, is a leader in infectious diseases and STD prevention and epidemiology. She and her colleagues[27] said WSW should be educated about possible STD transmission between women and education should be centered on common sex practices between WSW.

Reproductive health services are important topics to discuss with WSW patients. In the US, approximately 6 to 14 million children have parents who are lesbian or gay.[6] WSW may have children from previous relationships with men or may choose to become pregnant through a sperm bank, known donor, or heterosexual intercourse. Adoption and foster care are also options for WSW in many states. Other than dealing with societal stigma, studies have shown that children of lesbians have comparable development and life skills adjustment to children in heterosexual families.[16] "The American Psychological Association, the American Academy of Pediatricians, and the North American Council on Adoptable Children have each endorsed foster parenting, adoption, and parenting by same-gender couples, with the reassurance that their review of all the research on these children show that they develop normally."[28]

Even so, the process of starting a family can be emotionally, mentally, and financially challenging for WSW because of social stigma, discrimination, legal issues, and isolation. Zeidenstein[29] said the birth mother has unique challenges as she may have to "come out" again after becoming pregnant and once again as a lesbian mother. Zeidenstein[29] also identified that the comother can experience pain when her role as a parent is not recognized by the people in her life. Furthermore, state laws vary greatly. Legal action is required in most states for the nonbiological parent to be granted parental rights.[6] While legal implications are not within the scope of this article, it is important for NPs to encourage WSW to seek assistance from lawyers to ensure their wishes are granted and to ensure the comother has the rights of parenting she deserves. As an NP, referring WSW to agencies that are known to be nondiscriminatory can also be very helpful.[5]

Improving Practice Through Cultural Safety

NPs are responsible for creating a safe and caring atmosphere for each patient. A "safe" environment is defined by the patient. Key factors to a safe and caring context are reflection, environment, language, and knowledge. Context includes all the "in-betweens" of these 4 key factors. Most of context is made up of what is not said with words or language. A truly safe and caring health care context cannot be achieved by omitting any of the 4 elements. For example, a clinician who provides a safe environment but does not use inclusive language is not providing safe care.

Reflection of one's own feelings and possible biases about the WSW population is the first step in establishing a caring and safe patient-provider relationship. Acknowledging these feelings and examining personal biases is a necessary part of providing a safe and caring environment. McManus[30] said, "Awareness of how one's own attitudes affect clinical judgment and the development of a non-homophobic attitude are important steps in providing culturally competent care."[30] Reflection is an ongoing assessment of one's own feelings, reactions, and motivations. It cannot be done once as a single exercise; it is always evolving based on new experiences and interactions. The process of self-reflection is a personal mission of growth and development that requires continual self-evaluation.

Environment is the first factor that a WSW patient will experience. The waiting room can be a significant indicator of the level of acceptance a WSW patient can expect. The presence/absence of a posted nondiscriminatory policy, the art/pictures displayed, and the kinds of reading material available are all examples of environmental factors that a WSW patient will notice immediately. An example of a nondiscriminatory statement is: "This office appreciates the diversity of women [and men] and does not discriminate based on race, age, religion, ability, marital status, sexual orientation, gender, or perceived gender."[7]

The environment will likely affect the WSW patient's openness about her sexuality. "If the environment is perceived as completely unsafe, questioning by the provider will elicit an inaccurate history."[29] Many waiting rooms and clinics have brochures, posters, and educational materials that "reflect heterosexual experience."[29] Including posters or pictures depicting same-sex couples, brochures available that include same-sex experiences, a visible nondiscriminatory policy, and a visible symbol that the WSW population will recognize as a sign of safety are all ways to make an environment more welcoming to them.[4-6,16,30]

McManus[30] gives examples of symbols that health care providers can display to demonstrate a safe environment for the LGBT population:

**pink triangle (symbol of homosexuality in the concentration camps of Nazi Germany)
**A rainbow flag (an icon for the LGBT community since 1978, when it was first used in the San Francisco Gay Pride Parade)
**The Human Rights Campaign's equality symbol (a blue square with a yellow equal sign [5], which is well known to LGBT persons as a sign of acceptance)

Language used by the provider, staff, and in brochures and history/intake forms is also a strong indicator of safety for the WSW patient. Using inclusive, nonjudgmental, and open-ended questions are important to convey caring and safety. This provides a space for each patient to be as open as she chooses to be. A few examples of open-ended and nonjudgmental language include, "Do you have a partner or a spouse?" instead of "Do you have a husband?" or "Are you married?" Also asking, "Do you, or have you had, sexual relations with men, women, both, or none?"[4–6,16,30] This question is more likely to end with an honest response in comparison to simply asking the patient if she is sexually active.[30] "By taking a little time and asking a few sensitive questions, health care providers can create an environment of trust and inclusion."[5]

Knowledge and competency are associated with caring practice.[31] Understanding the health risks for WSW that are different than heterosexual women is valuable and necessary to provide quality care. The ability to refer patients to other providers who are known to be open and nondiscriminatory is helpful[6] and will enable patients to further trust their provider. The availability of information and resources ( Table 1 ) on WSW-specific health considerations is essential when providing care to this population.

Implications for NPS

In a qualitative study by Bjorkman and Malterud[13] on lesbian experiences with health care, 3 essential qualities were described as necessary for the health care provider: awareness, attitudes, and medical knowledge. This study reinforces the importance of personal attributes that play a role in developing a safe and caring patient-provider relationship.

Some suggestions given in the literature for providing a safe and caring health care context for the WSW population include health questionnaires that are inclusive of same-sex relationships or sexual practices, educational materials or brochures that are inclusive of same-sex relationships and sexual practices, open-ended questions from providers, a nonjudgmental approach to questions, images or posters with same-sex couples, and a nondiscriminatory statement.[6,16,30] While it is important to understand the common health disparities found in the WSW population, the population itself is full of unique individuals from every walk of life. Each individual will present a unique set of health issues and needs. Understanding the uniqueness and diversity of each woman allows the opportunity to provide individually tailored health care and best practices for this population.

In compliance with national ethical guidelines, the authors report no relationships with business or industry that would pose a conflict of interest.

Creating a Safe and Caring Health Care Context for Women Who Have Sex with Women
Posted: 07/12/2012; Journal for Nurse Practitioners. 2012;8(6):464 © 2012 Elsevier Science, Inc.

The purpose of this article is to introduce the concept of cultural safety as it relates to women who have sex with women and offer nurse practitioners who work with this population an integrated literature review regarding relevant research and recommended practices.

Introduction

Women who have sex with women (WSW) are a population that has long been stigmatized and marginalized within our society. Commonly, WSW are referred to as lesbian or bisexual. However, many WSW do not self-identify this way, so using the term WSW is more inclusive. This article will use WSW and lesbian interchangeably and will mention people of other sexual minorities: lesbian, gay, bisexual, and transgender (LGBT) to be compatible with references and citations.

There has been incremental improvement in the United States toward societal acceptance of the LGBT population, yet there is still stigma associated with living anything other than a heterosexual lifestyle.[1,2] Neville and Henrickson[2] posit that consequences of these attitudes lead to violence, homophobia, and heterosexism that affect the mental and physical health of the LGBT population. "Although homosexuality has been removed from the list of diagnoses in the diagnostic manual of the American Psychiatric Association, the relationship between homosexuality and sickness has proved more enduring in the minds of many providers."[1]

It is difficult to accurately estimate the size of the LGBT or WSW populations because of poor research methods, nonstandardization of terms, and the historical invisibility of the population. Different estimates are given in the literature, all of which are relatively low. The Institute of Medicine[3] (IOM) sentinel report on lesbian health from 1999 lists the estimated percentage at 2%–10% of the population. The range of 1%–10% is reflected in other references.[4–8]

Dibble et al[9] said, "Lesbians are a diverse group of women from every ethnic, religious, economic, cultural, and age group." Some agencies have brought attention to the health disparities and consequent need for culturally safe care, including the Joint Commission,[10] Healthy People 2010 and 2020,[11,12] and the IOM.[3]

Many nurse practitioners (NPs) are educated in the specific health and cultural needs of the WSW population and provide exemplary care for this group. However, although many NPs provide culturally safe care for WSW, there are also accounts of discrimination, abuse, assumptions, voyeurism, lack of knowledge, and substandard care toward the WSW population in health care.[4,5,13,14] Some WSW report that, after coming out to their health care provider, they were treated with physical roughness during their exam.[13] Some women have been denied care after their providers found out about their sexual orientation.[5] According to Bjorkman and Malterud,[13] since many health care providers assume that women are heterosexual, a woman who self-identifies as lesbian has to "choose to actively intervene and inform the professional about her lesbian orientation or passively pass as heterosexual." They also point out that the pressure to disclose sexuality is particularly present during gynecologic exams, when the provider doesn't understand when the patient reports being sexually active but not using contraception and having no possibility of being pregnant.[13]

Much of the literature on WSW identifies gaps in providing culturally safe care for this population. Cultural safety is defined as "the effective nursing practice of a person or family from another culture, and is determined by that person or family."[15] The purpose of this article is to introduce the concept of cultural safety as it relates to WSW and offer NPs who work with this population an integrated literature review regarding relevant research and recommended practice.

Literature Review

The literature review is organized by common health issues found among WSW. The issues discussed are obesity and cardiovascular disease (CVD), cancer and screening, mental health and substance abuse, and sexually transmitted diseases (STDs) and reproductive health.

Obesity and Risk for Cardiovascular Disease

Many sources suggest that WSW may tend to have higher rates of obesity than heterosexual women.[6,9,16] "Lesbians are more likely than heterosexual women to have high body mass index, waist circumference, and waist-to-hip ratio; however, they are also more likely to engage in regular exercise."[6] Boehmer and Bowen[17] also found more obesity in women of sexual minority compared to women with a male partner.

There is conflicting information on the risk of CVD for the WSW population. Roberts[16] said, "Research has found increased risk for CVD in lesbians." On the other hand, Mravcak[6] said, "There is no proven increase in the risk of CVD among lesbians and bisexual women." Risk factors for CVD in the WSW population provided by Roberts include "higher rates of obesity, smoking, alcohol use, and less intake of fruits and vegetables."[16]

Cancer and Screening

Cervical Cancer and Dysplasia. Hutchinson et al[4] said, "All women, regardless of sexual preference, are at risk for cervical cancer." Many providers are under the assumption that WSW do not need regular Papanicolaou (Pap) smears because of perceived low risk of cervical dysplasia and cancer.[6,7] This belief may also be held by many WSW themselves.[16] However, human papillomavirus (HPV), the believed cause for 90% of cervical dysplasia, can be transmitted between women.[5] Cervical neoplasia has been found in WSW with no reported history of male partners.[18] In addition, most WSW do report a history of male sexual partners.[4-7]

There has been evidence that WSW have lower rates of cervical cancer screening than do heterosexual comparison groups.[16] One study of 7,000 lesbians cited by Hutchinson et al[4] reported, "Lesbians had higher rates of abnormal Pap results than rates reported in the general US population." Clearly, best practices suggest that WSW should not be excluded from regular cervical cancer screening. Moreover, NPs may need to educate WSW that they need this screening.

Breast Cancer. Several reasons are identified in the literature why WSW may be at a higher risk to develop breast cancer than heterosexual women. It is believed that WSW do not seek preventive mammograms as often as heterosexual women, citing reasons of mistrust of health care providers, negative past experiences, and perceived homophobia in the health care setting.[4] However, the data suggesting that WSW do not receive screening mammography as much as heterosexual women is not consistent. Mravcak[6] said, "Rates of mammogram screening in lesbians and bisexual women are similar to those in heterosexual women." Also discussed in the literature are lower rates of breast self-exam (BSE) among the lesbian population.[5]

It is commonly believed that many WSW are at a higher risk for developing some cancers as a result of higher rates of nulliparity, smoking, alcohol use, and obesity.[4,16] O'Hanlan et al[7] identify these risks and the use of menopausal hormone replacement therapy as a risk. This information is not well researched and needs further study. As Spinks et al[5] pointed out, "Current research has not accurately identified the incidence of breast cancer in lesbians; however, simply being female places lesbian clients at risk." NPs need to encourage WSW to perform monthly BSE, have regular cancer screening visits with a health care provider, and screening mammograms by following the guidelines for best practices as suggested for all women.

Ovarian Cancer. There is little research available about the occurrence of ovarian cancer in WSW compared to the general population of women. Dibble et al[9] performed a study on risk factors for ovarian cancer for lesbians and heterosexual women. This study of over 1,000 women found, "As expected from previous reports, the lesbians had significantly fewer pregnancies, miscarriages, and abortions and lower use of birth control pills. These variables place lesbians at a higher risk for developing ovarian cancer."[9] "Whether women are at increased risk for ovarian cancer secondary to exposure to HRT [hormone replacement therapy] is not clear. The prevalence of HRT usage among lesbians is unknown."[9] In addition, the authors suggest it would be helpful to include sexual orientation in tumor registry data.[9]

Mental Health

Mravcak[6] said, "Most lesbians and bisexual women are emotionally healthy and well-adjusted." However, mental illness, especially depression, occurs in the WSW population. Depression is the most common mental illness reported in WSW[16] and has shown in some studies to occur in higher rates in WSW than in heterosexual women.[19]

ABSTRACT
Objectives: To determine whether salaries differ by gender in a relatively homogeneous cohort of physician researchers and, if so, to determine if these differences are explained by differences in specialization, productivity, or other factors.

Design and Setting: A US nationwide postal survey was sent in 2009-2010 to assess the salary and other characteristics of a relatively homogeneous population of physicians. From all 1853 recipients of National Institutes of Health (NIH) K08 and K23 awards in 2000-2003, we contacted the 1729 who were alive and for whom we could identify a mailing address.

Participants: The survey achieved a 71% response rate. Eligibility for the present analysis was limited to the 800 physicians who continued to practice at US academic institutions and reported their current annual salary.

Main Outcome Measures A linear regression model of self-reported current annual salary was constructed considering the following characteristics: gender, age, race, marital status, parental status, additional graduate degree, academic rank, leadership position, specialty, institution type, region, institution NIH funding rank, change of institution since K award, K award type, K award funding institute, years since K award, grant funding, publications, work hours, and time spent in research.

Results: The mean salary within our cohort was $167 669 ($158 417-$176 922) for women and $200 433 ( $194 249-$206 617) for men. Male gender was associated with higher salary (+$13 399) even after adjustment in the final model for specialty, academic rank, leadership positions, publications, and research time. Peters-Belson analysis (use of coefficients derived from regression model for men applied to women) indicated that the expected mean salary for women, if they retained their other measured characteristics but their gender was male, would be $12 194 higher than observed.

Conclusion: Gender differences in salary exist in this select, homogeneous cohort of mid-career academic physicians, even after adjustment for differences in specialty, institutional characteristics, academic productivity, academic rank, work hours, and other factors.

Introduction
The connection between social relationships and mental health is a fundamental component of both the sociological and psychiatric literatures. Robin W. Simon, PhD, is a sociologist whose work has focused on social relationships—especially marriage—and mental health for 25 years.

Why is Marriage Associated with Mental Health?
“Sociologists have long been interested in the link between social relationships and mental health,” explains Dr. Simon. “Let’s take marriage as an example. At this point, hundreds of studies document a robust relationship between marriage and improved mental health: married people report significantly fewer symptoms of depression and are significantly less likely to abuse substances than their non-married counterparts. This is because marriage provides social support—including emotional, financial, and instrumental support. Also, married people have greater psychosocial (or coping) resources than the non-married—higher self-esteem and greater mastery. Social support and psychosocial resources not only increase emotional well-being but also buffer the negative emotional effects of stressors that people experience during the life course.”

There are, of course, many nuances in this narrative. For instance, poor marital quality can lead to lower levels of well-being among the married than the non-married, because marital conflict is highly stressful. However, although it was believed for decades that men derive greater benefit from marriage than women, Dr. Simon’s 2002 study1 and other sociological research show that the mental health advantage of marriage is evident among both genders. At the same time, it appears that marriage is less beneficial for individuals with a mentally ill than an emotionally healthy spouse.2

The Direction of the Relationship Between Marriage and Mental Health
The psychiatric literature recognizes the protective effects of marriage for mental illness. For example, among adults with schizophrenia, being in a marital or cohabiting relationship is associated with a 5-year delay in experiencing a first episode of psychosis (FEP) and higher quality of life, and is a significant predictor of symptom remission within 1 year of FEP.3,4

There is a debate about whether a person’s depression increases the risk of marital loss through divorce, or whether a marital loss itself (including cases where a spouse dies) is largely responsible for depression onset.

The former scenario fits into the hypothesis known as social selection, which states—to summarize it roughly—that healthy individuals gravitate toward intimate relationships and are seen as desirable partners. This view assumes that people who marry are more likely to have better mental health, anyway, and that “the healthiest, most robust people select into marriage,” says Dr. Simon. The alternative hypothesis—the perspective that most sociologists embrace—is social causation, which holds that marriage wards off mental illness and improves mental health by virtue of its built-in support system.

In a 2002 study1 Dr. Simon analyzed longitudinal data from a large nationally representative sample to examine, among other things, both the social causation and selection hypotheses of the relationship between marital status and mental health.

“In this study I examined whether a change in marital status between study onset and endpoint caused a change in mental health,” explains Dr. Simon. “I found that people who became divorced and widowed during the study experienced a significant decline in mental health between data points, which supports the social causation hypothesis. But those who divorced also reported more symptoms before the actual divorce. This latter finding could be interpreted as evidence that people who experience mental health problems are more likely to get divorced (in agreement with the social selection hypothesis). I argued, however, that some of these people might have been experiencing marital conflict at study onset, increasing symptoms of depression and alcohol abuse. In terms of marital gain, people who got married during the study reported a significant decrease in symptoms of depression and alcohol abuse, but there was no evidence that mentally robust people are more likely to marry than their less healthy peers.”

In an era where cohabitation and state-sanctioned same-sex marriage are increasingly common, do the mental health benefits of marriage apply exclusively to heterosexual marriages?

Unfortunately, there are no existing national data sets that would allow us to answer this question. Studies addressing this issue are underway, however, and Dr. Simon predicts that there would be no difference in the mental health benefits of marriage between individuals in heterosexual and same-sex marriages. “If anything,” she says, “marriage may be even more protective for people in same-sex marriages, because they fought long and hard for their partnerships to be recognized by the state.” As for cohabitation, Dr. Simon says that studies show that cohabitation, too, is good for mental health, “though not as good as marriage.”

“We still have much to learn about why marriage in particular, and social relationships in general, improve mental health,” concludes Dr. Simon, “but sociological research on this topic is clear; having a deep emotional connection with another person provides individuals with social support and coping resources, a sense of purpose and meaning in life, an important social identity, and feelings of social integration and mattering—which are all important for both the development and maintenance of mental health.”Disclosure: Dr. Simon reports no affiliations with, or financial interests in, any organization that may pose a conflict of interest.
