Women over age 55 face some increased health risks, including the risk of bone and muscle loss. There are therapies to help reduce these risks, and a recent study has found that a specific hormone, Dehydroepiandrosterone (DHEA), may help increase muscle mass and prevent bone loss in older women. However, these results were not found among older men.

The study, published in Clinical Endocrinology, consisted of researchers analyzing data from four separate randomized clinical trials, all double-blinded and placebo-controlled. The studies were designed to identify the effects on bone composition and bone mineral density of administering oral DHEA to raise levels in men and women ages 55 to 85 to those found in young adults. This is because bone and muscle mass loss is a result, in part, of decreased androgen and estrogen hormone production as adults get older. Therefore, researchers hypothesized that increasing DHEA hormone levels may help offset bone and muscle mass loss.

After comparing the four studies, researchers found improved bone mineral density in women’s lumbar spine, total hip, and trochanter, but not in men’s. However, among men, they found a statistically significant decrease in fat mass. One downside of the study is that none of the trials specifically targeted women with osteoporosis, which may have impacted the results. The researchers have indicated that further studies with women who already have osteoporosis, and examining long-term therapy may be beneficial to gather more information on to how to use this therapy to help both aging men and women.

A recent article published in JAMA Pediatrics highlights a study conducted with the intention of identifying physical activity levels of adolescents and young adults in the United States, and more specifically, breaking down and examining the activity levels by sex, income, and race/ethnicity. The findings indicate that overall, females participated in less physical activity than males, and that minority racial/ethnic groups and individuals with lower incomes were typically less physically active. [1]

The study itself was conducted from 2007 to 2016 with self-reported physical activity information collected from 9,472 adolescent and young adult participants: 4,771 males and 4,701 females. The average age of the participants was 20.6. [1] The study found that among teenagers between ages 12 and 17, around 88% of the males reported being physically active, compared to about 78% of females. However, between the ages 18 and 24, these rates drop to 73% for males, and only about 62% for females, indicating that after high school, fewer women participate in physical activity. This disparity is even greater among minority groups. For example, among female participants aged 18 to 24, around 71% of white women reported participating in any moderate or vigorous physical activity, compared to only 45% of black women. When looking at the data with regards to income, about 80% of women in the highest income bracket remained physically active after age 17, compared to between 45% to 55% of women below the poverty line. [2]

Researchers have considered reasons for these disparities and how to address them. An adolescent medicine specialist from Harvard University, Dr. Holly Gooding, was not involved in the study, but believes that socialization norms may contribute, as teen girl socialization is not often centered around physical activities, unlike with boys. She also points out that schools and communities that serve minority populations often have fewer resources such as athletic fields or safe spaces to participate in physical activity outside of school. Dr. Charlene Wong, one of the authors of the study also cited the increased use of mobile devices as contributing to decreased physical activity for all groups. Dr. Wong suggests that this study has demonstrated where to aim for improvements in physical activity in young people, and that it may be helpful to use programs in schools to develop healthy physical activity habits, especially among women, that can be carried into adulthood.

The Mediterranean Diet is known to have many health benefits, but a recent study published in the journal Stroke examined the impact that the diet has specifically on the risk of stroke, and whether the diet impacts the risk of stroke in men and women differently. The Mediterranean Diet emphasizes eating fish, fruits, vegetables, and nuts, and using olive oil as the main source of fat. It also includes moderate alcohol consumption, but only small quantities of meat and dairy. [1]

The study was conducted in the United Kingdom, among a population-based group of 23,232 individuals aged 40 to 77, of whom 54.5% were women. The individuals in the study were followed for 17 years, with stroke incidence calculated and stratified by sex and risk of cardiovascular disease. To determine adherence to the Mediterranean diet, participants completed a 7-day diet diary. [1]

The findings indicate that overall, the risk of stroke among all the study participants decreased significantly with greater adherence to the Mediterranean diet. Interestingly, when stratified by sex, the risk of stroke among women was reduced even more, and although there was a decrease of risk of stroke among the male population, it was not significant. [1] The overall risk of stroke incidence decreased 17% among both men and women, decreased 22% among just women, and decreased only 6% among men. [2] Researchers are unsure what causes the difference in risk reduction among men and women on the Mediterranean diet, and suggest further studies to understand more clearly associations between diet and risk of stroke.

A recent study in the journal Radiology reports that heading a soccer ball, which is a common action for both male and female athletes in the sport of soccer, may pose more of a health risk for women than for men. The study took place between 2013 and 2016, and was a subset of a larger study of both male and female amateur soccer players. The study included 94 athletes - 49 men and 49 women - matched for age and history of heading a soccer ball. Among the females in the study, there was a median of 469 soccer ball headings a year, compared to 487 among the male study participants. The investigators used diffusion-tensor imaging, which is a type of MRI-technology, to examine differences in the structure of white matter in the brain of the participants. [1] In an interview about the study, the lead author, Michael Lipton, describes white matter as a connector of neurons within the brain, and that alterations or abnormalities in white matter may be associated with decreased cognitive function, such as issues with memory. [2]

The results of the study indicate that the female participants who were exposed to the same amount of soccer ball heading as male participants experienced more alteration to the microstructure of their brain’s white matter than the males. This suggests that women may respond differently, or have greater sensitivity, to low-level, repetitive, trauma to the brain than men. [1]

This study highlights the importance of sex-inclusive research, and examining sex differences in a variety of disciplines. While Lipton makes it clear that this doesn’t mean women or men should stop playing soccer, it points to a need for additional research, which may help improve athlete health and the safety of sports.

Trauma is a complex concept, but has been succinctly defined by the Substance Abuse and Mental Health Services Administration (SAMHSA) as resulting “from an event, series of events, or set of circumstances that is experienced by an individual as physically or emotionally harmful or life threatening” [1]. Trauma is pervasive, and while many individuals recover without negative effects, for some, even if experienced for just a short time, trauma can have long-lasting effects on mental, physical, and emotional health. For this reason, it is important to address trauma and provide support for individuals who have experienced traumatic events. Health practitioners, or any professional that works in a service sector, will encounter individuals that have experienced trauma - not just those that work in the behavioral health field [1]. This is why it is critical to understand what trauma-informed care is, and how to use it in practice.

According to SAMHSA, a trauma-informed approach to care involves:

  • Realizing that trauma has a widespread impact on individuals and that there are different possible paths to recovery

  • Recognizing symptoms of trauma in all individuals within a system

  • Incorporating what is known about trauma into policies and practices

  • Avoiding re-traumatization [1]

SAMHSA has also indicated that there are six key principles vital to using a trauma-informed approach in practice: safety; trustworthiness and transparency; peer support; collaboration and mutuality; empowerment, voice and choice; and cultural, historical, and gender issues. This last principle includes the provision of gender-responsive care, or interacting with individuals with the consideration of specific needs based on gender [1].

Ensuring that trauma-informed care is gender-responsive is important, because women and men typically experience different types of trauma, and react to trauma in different ways. For example, women are more likely to experience trauma at the hands of an intimate partner, while the risk of trauma for men is more often from a stranger. Naturally, the effects of these types of trauma often differ, as do the processes to recover from them [2].

A gender-responsive, trauma-informed approach to care should be used in all environments, but it is particularly important to use this approach when treating women in certain settings, such as mental health care and substance use treatment. This is because mental health issues and substance use disorders are often co-occurring among women. Additionally, while both men and women experience these issues, for women, there is a strong link between these disorders and trauma. Research suggests that between 55% to 99% of women that have co-occurring mental health and substance use issues experienced trauma in the form of abuse within their lives [3]. For these reasons, it is important that both mental health care and treatment for substance use be both trauma-informed and gender-responsive.

This year, September 16 marked Global Female Condom Day. Compared to other forms of birth control, female condoms are not widely known about, although they have many advantages. The most important aspect about female condoms is that they are the only woman-initiated birth control product that protects women from both pregnancy and STI’s. While male condoms protect against both of these conditions, a woman does not have complete control over their use as she does with a female condom.

Other benefits of female condoms include:

  • They are non-hormonal for women unable to use hormonal birth control
  • They are latex-free for those with latex allergies

  • There are a variety of brands sold over-the-counter

  • Their design allows for pleasure enhancement for men and women during intercourse

Female condoms have the potential to prevent unwanted pregnancy, especially in countries and regions where prescription birth control and other forms of women-initiated birth control, like IUDs, are not readily available. Additionally, they could be instrumental in reducing HIV/AIDS and other STI rates by giving women more control over protection during intercourse.

The first step to achieving more widespread use of the female condom is education and awareness. For more information on the female condom, click here.

It’s been over a year since the controversial Texas law (House Bill 2) leading to abortion clinic restrictions passed, and the repercussions are starting to be felt throughout the state. The law, which was passed on July 18, 2013, created several new requirements, which abortion clinics need to meet to remain in operation. One requirement, which came into effect November 2013, called for clinic doctors to have admitting privileges at a hospital within a certain radius of the clinic. Since then, not all doctors could comply, and the number of clinics in Texas decreased by half from 41 to 20. The last restriction comes into effect on September 1 and requires that all clinics upgrade their facilities to make them ambulatory surgical centers. This will likely to lead to the closure of several more clinics.

This final requirement calls for clinics that do not currently meet its standards to renovate facilities to have a specific hallway width, establish full male and female locker rooms and include a janitor’s closet, among other things. Proponents of the law claim that these changes protect the health of women undergoing an abortion. However, Heather Busby, executive director of NARAL Pro-Choice Texas, states that abortions are among the safest office-based procedures performed, with a low complication rate of under 0.05%. Therefore, she points out that the requirements are not linked to the safety of the procedure and are unnecessary.

According to Busby, since the number of clinics in Texas has dropped, women are having to wait longer in their pregnancy before they are able to have an abortion, and are having to travel greater distances, or even leave the state. Unfortunately, watchdogs are predicting that when the last requirement comes into effect in September, even more clinics will close, potentially bringing the number down to around 6 or 8 clinics in the state. Busby points out there are already no clinics in East Texas or in the Rio Grande Valley, and the one clinic left in El Paso is at risk of closure. Texas clinics have filed a lawsuit to stop the last requirement from going into effect, but if it fails, women in Texas may find it increasingly difficult to receive safe abortions. Other states across the country are trying to pass similar laws in an effort to restrict women’s access to healthcare.

On March 25, the Supreme Court heard arguments regarding challenges to the contraception mandate of the Affordable Care Act, with a decision expected to come down in late June. Here’s a rundown of the main aspects of this important case:

What is being challenged?

Under the contraception mandate in the Affordable Care Act, employers are required to provide employees with comprehensive health insurance, including a range of contraceptive methods for women. Organizations exempt from this mandate include small employers that are not required to provide any health insurance to employees, religious organizations and organizations with select insurance plans that were grandfathered in. Religiously-affiliated non-profit organizations may request exemptions as well. The main issue being decided is whether for-profit organizations can choose not to cover contraceptive care in health insurance plans based on religious objections. This comes down to the scope of the Religious Freedom Restoration Act of 1993 (RFRA), which currently does not apply to for-profit corporations.

Who is challenging the law?

The cases were brought by two for-profit corporations, that while not religious or religiously-affiliated, claim to operate based on religious principles. The corporations are Hobby Lobby, a craft store chain based in in Oklahoma City and owned by a Christian family, and Conestoga Wood Specialties, a Pennsylvania-based company that makes wood cabinets and is owned by a Mennonite family.

Why is the law being challenged?

The corporations challenging the contraception mandate believe that certain forms of birth control drugs and devices, including the morning after pill and IUDs, are equivalent to abortion because they may prevent embryos from implanting in the uterus. As such, they believe that covering the cost of these forms of contraception makes the them complicit with abortion. The corporations do not oppose all forms of birth control, including condoms, diaphragms, sponges, certain drugs and sterilization.

How is the administration defending the law?

Donald B. Verrilli, Jr., the current solicitor general who is representing the U.S. administration, has stated that the law offering comprehensive contraceptive care to women promotes public health and ensures equal access to healthcare for women. He also emphasized that it should be doctors, not employers, who should decide the best form of contraception for women. Additionally, a brief from the Guttmacher Institute points out that many women cannot afford highly effective forms of birth control, and so upholding the law will reduce unplanned pregnancy and abortions.

What are the potential outcomes and implications of the decision?

There are many ways the decision could go, each with varying repercussions. If the Supreme Court decides the RFRA does not cover for-profit organizations, it will end those organizations’ ability to challenge the contraception mandate based on religious beliefs. The Supreme Court could decide the RFRA does apply to for-profit organizations, but still rule on the side of the administration. This would be a less decisive win for the administration that would likely lead to more challenges. If the Supreme Court rules in favor of Hobby Lobby and Conestoga Wood Specialties, it will impact women’s access to affordable birth control, while opening the door to other religious objections raised by employers, such as hiring gay and lesbian individuals, or offering benefits to same sex spouses.

In early February, the American Heart Association published new guidelines aimed at preventing stroke in women. Due to several factors, women are more prone to stroke and generally have more difficulty recovering from stroke than men. A stroke occurs when a blood clot forms in a vessel leading to the brain, cutting off its oxygen supply. Women suffer strokes more often than men because they tend to live longer than men, undergo reproductive hormonal changes through contraceptives and hormone replacement therapies, and face an increased risk of stroke during pregnancy.

Due to these risk factors, the American Heart Association outlines the following guidelines:

  • Women with a history of high blood pressure before pregnancy may be able to take low-dose aspirin after the first trimester of pregnancy. Similarly, pregnant women with moderately high blood pressure may be able to be treated with medication.
  • A history of preeclampsia, or high blood pressure during pregnancy, should be considered a risk factor for stroke, along with cholesterol, obesity and smoking.
  • Women should be tested for high blood pressure prior to starting hormonal birth control, and although data is conflicting, hormone replacement therapy during menopause may increase the risk of stroke, so should not be used for stroke prevention.
  • As migraines with aura (sensory warning signs, such as tingling sensations or flashing lights) have been linked to stroke, women who experience migraines with aura should quit smoking.
  • Women over 75 should be tested for atrial fibrillation, another risk factor of stroke.

It is vital that stroke awareness and prevention begins at an early age and that blood pressure is monitored and treated appropriately throughout a woman's life. It is also important to note that these are only guidelines and that cases will vary by individual, so it is important to discuss issues or concerns related to stroke with your doctor.
