Therapies to change people’s sexual preference cause suicidal ideation

Conversion therapy programs that attempt to change people’s sexual preference dramatically increase their risk of suicide, a study in the July issue of APHA’s American Journal of Public Health finds.

Researchers examined data from a 2016-2018 national survey of over 1,500 individuals ages 18 to 59 who identify as gay, lesbian, bisexual or another non-heterosexual identity. Seven percent had experienced conversion therapy, with 80% reporting it was under the auspices of a religious group.

After adjusting for demographics and adverse childhood experiences, researchers found that participants were twice as likely to think about suicide over their lifetime than people with the same sexual preferences but who had never experienced conversion therapy. They were also 75% more likely to attempt suicide.

Conversion therapy typically uses shame and sometimes physical pain, such as electric shock, to re-program people’s sexual attraction.

The therapy is “ineffective and may compound or create problems, such as depression, guilt, intimacy avoidance and, as we have shown here, suicidal ideation and suicide attempts,” the researchers said.

Sugary drink taxes may reduce purchases and improve people’s health

Sugary beverage excise taxes enacted in San Francisco and Oakland, California, resulted in a 1-cent increase per fluid ounce in both cities, a study in July’s AJPH finds.

Other U.S. cities that have increased excise taxes on sugary drinks have shown a drop in purchases and consumption. Overconsumption of the beverages places people at risk for obesity, Type 2 diabetes, heart disease and other chronic conditions.

A few years ago, Oakland and San Francisco passed ordinances that imposed excise taxes on sugary drinks, such as soda, energy drinks and fruit-flavored beverages.

Researchers gathered prices of the beverages at stores before the tax increase and after the tax increase. They compared the excise-taxed prices to those in two other Bay Area cities that did not implement a sugary-drink excise tax. They found that prices in Oakland and San Francisco increased by about 15%.

The increase could translate into fewer sales, resulting in over 5,000 fewer cases of obesity and save over $50 million in health care costs over the next decade in the cities, according to modeling research cited in the study.

Medical exemptions for vaccines increase in California following ban on exemptions for personal belief.

Medical exemptions for kindergartners’ vaccinations have increased in California as a workaround to the state’s law ending vaccine exemptions for personal belief, a study in AJPH’s July issue finds.

In 2015, California eliminated nonmedical vaccine exemptions. But in regions where those exemptions had proliferated before the measure took effect, researchers discovered a rise in medical exemptions, according to data from the California Department of Public Health.

Medical exemptions are granted for ailments such as congenital conditions and rare allergic reactions. It is unlikely that those chronic ailments would spring up in mass in communities that formerly had clusters of nonmedical vaccine exemptions for personal belief, the researchers said.

In those regions between 2015 and 2018, medical exemptions increased at public schools from 0.2% to to 1%. In private and charter schools, medical exemptions increased from 0.4% to 5.3% and 0.3% to 5%, respectively.

The regional clusters of medical exemptions in California present “a continued threat to local herd immunity and creates an elevated risk of vaccine-preventable diseases,” researchers said.

Georgia law effective at reducing late-term abortions

Georgia law prohibiting late-term abortions effectively reduced the procedure during the desired weeks, a study in July’s AJPH finds.

Researchers examined pregnancy data from the Georgia Department of Health between 2007 and 2017. They compared abortion data before and after enactment in 2012 of a state law banning abortions after 21 weeks, with some exceptions such as preserving the pregnant woman’s life or her having a serious medical impairment.

Abortions declined dramatically, especially after 2015 when the policy went into full effect. For example, in 2007, Georgia doctors performed 809 abortions after 21 weeks. In 2017, Georgia doctors performed seven. Data showed that a significant number of out-of-state residents had been coming to Georgia for late-term abortions before the law took effect.

“Given that economically vulnerable and young people are more likely to need later gestational age services, and that racial and ethnic minority groups are more likely to experience economic vulnerability because of racism, the policy has strong potential to worsen the already-existing reproductive health disparities by income, age and race/ethnicity in the Southeastern region,” the researchers said.
