American Journal of Public Health August 2019 issue research highlights:
High school students increased marijuana use, decreased tobacco and alcohol use 1991-2017
Newswise — From 1991 to 2017, the prevalence of marijuana-only use among U.S. high school students increased from 0.6% to 6.3%, while the prevalence of use of alcohol only or cigarettes only significantly declined. Dual use of alcohol and marijuana increased from 3.6% to 7.6%, while dual use of alcohol and cigarettes declined from 11.8% to 1.7%. The prevalence of poly use of alcohol, cigarettes and marijuana declined from 9.4% to 4.4%.
Researchers also measured an enlarged disparity in use of marijuana only by race/ethnicity. Use of marijuana increased 11.5% among non-Hispanic blacks and increased 8.1% among Hispanics, compared with an increase of 3.4% among non-Hispanic whites. Authors concluded the use patterns of alcohol, cigarettes and marijuana among youths have changed with a surge in use of marijuana only, especially among racial/ethnic minorities.

Nutri-Score labeling leads to more nutritious grocery purchases
Researchers compared the overall nutritional quality of students’ food purchases when food items were labeled with the Nutri-Score label, the Reference Intakes label or no label at all in this randomized controlled trial. The Nutri-Score is a graded and color-coded label that indicates whether a food product is relatively healthy in terms of nutritional quality (depicted as A and dark green) or less healthy (E and dark orange). The Reference Intakes label is a nutrient-specific front-of-pack nutrition label.
The study showed the Nutri-Score label appeared to improve the nutritional composition of students’ food purchases relative to the Reference Intakes label or no label. Shopping cart content was lower in calories and saturated fatty acids and higher in fruits and vegetables in the Nutri-Score arm of study participants than in the other arms.

Barbershop HIV intervention reduces sexual risk behaviors
Barbershops in Brooklyn, New York, neighborhoods with high rates of heterosexually transmitted HIV were randomized to either an intervention or control program. Men were recruited from barbershops between 2012 and 2016 and participated in a single small group, peer-led session focused on HIV risk reduction skills and motivation, community health empowerment, and identification of personal strengths and communication skills. The outcome was defined as one or more acts of condomless anal or vaginal sex in the preceding 90 days at a 6-month interview.
Researchers found 64.4% of men included in the intervention exposure reported no condomless sex in the preceding 90 days six months after the intervention, compared with 54.1% of men included in the control group. Researchers concluded program exposure resulted in reduced sexual risk behaviors.
