TIME (7/25, Sifferlin) reported, “Boys and girls as young as age eight can experience dissatisfaction with their bodies that can predict their risk for eating disorders later in life,” according to a study published in the July issue of the British Journal of Psychiatry. After following “about 6,000 children until they were 14 years old,” researchers found that “at age eight, 5% of girls and 3% of boys were unhappy with their bodies.”

Medscape (7/24, Melville) reported that a new meta-analysis published in The Lancet Psychiatry suggests that “smoking itself may play a causative role in the development of psychotic illness.” The analysis, which “included 61 studies with data through 2014 involving 14,555 tobacco smokers and 273,162 nonsmokers,” including international populations, found that “57% of people with a first episode of schizophrenia were already smokers, for an overall odds ratio of 3.22 (95% confidence interval [CI], 1.63 – 6.33), with some evidence of publication bias.” In addition, “daily smokers were still approximately twice as likely to develop new psychotic disorders as nonsmokers (relative risk, 2.18; 95% CI, 1.23 – 3.85)” and developed such disorders about one year earlier than nonsmokers.

The AP (7/24, Merchant) reported, “Suicide is the leading cause of death in jails after natural illness.” People who are incarcerated “take their own lives three times more often than the average population, according to a 2010 study cited in the National Study of Jail Suicide.” A 2013 article on suicide in Texas jails that appeared in the LBJ Journal of Public Affairs said that jail environment stressors include “isolation, loss of control, conflict with other inmates or staff, frustration with legal proceedings, or distress and shame over incarceration.”

The Guardian (UK) (7/23) reports that research published in BMJ Open suggests that individuals “over 50 who are healthy, active, sociable and highly educated are at more risk of harmful drinking than their less well-off peers.”

The Telegraph (UK) (7/24) reports that “the findings are based on responses from 9,000 over 50s who took part in the English Longitudinal Survey of Ageing.” While the investigators “found that heavy drinking was no linked to feeling lonely or depressed, men who lived on their own were more likely to consume harmful amounts of alcohol.”

The Los Angeles Times (7/24, Healy) reports in “Science Now” on studies presented at the Alzheimer’s Association International Conference suggesting that exercise may benefit people with mild cognitive impairment and “mild to moderate Alzheimer’s disease.” In each of these studies, “subjects were asked to participate in three-to-four sessions of aerobic conditioning – ranging from 45 minutes to an hour – a week.” The goal “was to get participants working at between 70% and 80% of their aerobic capacity.”

The AP (7/24, Neergaard) reports that researchers found that “vigorous workouts by people with mild memory impairment decreased levels of a warped protein” called tau that is “linked to risk of later Alzheimer’s – and improved quality of life for people who already were in early stages of the disease.” One study involving magnetic resonance imaging scans demonstrated that “exercisers experienced increased blood flow in brain regions important for memory and thought processing – while cognitive tests showed a corresponding improvement in their attention, planning and organizing abilities.” Dr. Laurie Ryan, of the National Institute on Aging, cautioned, however, that “it’s too soon to say that [exercise] lowers risk’ of worsening memory…saying longer studies must test if sticking with exercise makes a lasting difference.”
