In “Vital Signs,” the New York Times (4/3, D6, Bakalar, Subscription Publication) reports, “Snorting and stopping breathing during sleep are associated with depression, even in people whose symptoms do not meet the criteria for a diagnosis of obstructive sleep apnea,” according to a study published in the April issue of the journal Sleep. After studying “9,714 men and women participating in an ongoing national health survey by the Centers for Disease Control and Prevention,” researchers found that “among those with a diagnosis of obstructive sleep apnea, depression was more than twice as common among men and more than five times as common among women, compared with those who did not have the condition.”

Bloomberg News (4/3, Ostrow) reports, “The 15 percent of US high school seniors who abuse alcohol and drugs first began using them at age 14 or 15,” according to a study published online April 2 in the Archives of General Psychiatry. Adolescents “whose substance abuse caused problems socially, in school or with the law, started drinking or doing drugs when they were 14 or 15 years old, the research found. By the time kids reach age 18, almost half consumed at least 12 drinks a year and 15 percent were abusers, according to the report.”

HealthDay (4/3, Preidt) points out that after analyzing “data from a US survey of more than 10,000 teens between the ages of 13 and 18,” researchers found that “more than 78 percent of the oldest teens had consumed alcohol, about 47 percent consumed at least 12 drinks a year, and about 15 percent met the criteria for alcohol abuse.” In addition, the study “found that 81.4 percent of the oldest teens reported the opportunity to use illicit drugs, 42.5 percent used drugs, and 16.4 percent were drug abusers.” Reuters (4/3, Seaman) also covers the story.

The Washington Post (4/1, A4, Brown) reported, “Numerous studies have shown that repeated deployment is a ‘risk factor’ for” post-traumatic stress disorder (PTSD). For example, a study published in the March issue of the American Journal of Public Health “examined the experience of 66,000 Marines who served in Iraq. Those with two deployments had almost twice the rate of PTSD as those deployed once.”

PTSD Susceptibility May Be Partially Determined By Gene Variants. BBC News (4/2) reports, “Susceptibility to post-traumatic stress disorder (PTSD) could be partially determined by gene variants,” according to a study published in the Journal of Affective Disorders. After examining “DNA from 200 members of 12 families who survived the 1988 Armenian earthquake,” researchers found that “those who carried two gene variants which affect the production of serotonin — which affects mood and behaviour — were more likely to display symptoms of PTSD.”

MedPage Today (4/1, Smith) reported, “People said they would pay more to avoid some serious medical conditions than they would to avoid severe mental illnesses, such as schizophrenia and depression,” according to survey results published in the April issue of the journal Psychiatric Services. In the survey involving some 1,000 randomly chosen US adults, “respondents recognized that the two mental conditions had a health burden comparable to or higher than diabetes, below-the-knee amputation or partial blindness, according to Dylan Smith, PhD, of Stony Brook University in Stony Brook, NY, and colleagues.” Notably, “for a comparable benefit in terms of quality of life, participants in the study were willing to pay about 40% less to avoid the psychiatric illnesses,” the study authors reported.

The Huffington Post (3/30, Chan) reports, “Soldiers, police, firemen and people who’ve suffered abuse aren’t the only ones with a high risk for post-traumatic stress disorder (PTSD) — a new study” published online March 29 in the Journal of Traumatic Stress “shows that 911 dispatchers may be at risk, too.” Investigators “from Northern Illinois University found that the 911 dispatchers still experienced the emotional distress associated with PTSD, even though they were not directly in the traumatic event.”

The Time (3/30, Sifferlin) “Healthland” blog reports that for the study, “researchers questioned 171 emergency dispatchers currently working in 24 US states. The dispatchers — predominately white women around age 38 with more than 11 years of dispatching experience — were asked about the types of calls they answer and their corresponding emotional distress.” Next, “participants…rated the types of calls that caused great distress and were asked to recall the worst call they ever received.”

“The unexpected injury or death of a child accounted for 16 percent of the calls dispatchers identified as their worst trauma,” HealthDay (3/30, Dallas). “The study authors noted that the dispatchers experienced a high level of distress following an average of 32 percent of potentially traumatic calls. In addition, 3.5 percent of the dispatchers reported symptoms severe enough to be classified as PTSD.”
