Leventhal and colleagues conducted a prospective cohort survey of 2572 adolescents and collected data at baseline from January 2 through September 28, 2016 (11th grade), and at follow-up from January 1 through August 10, 2017 (12th grade), at 10 high schools in Los Angeles, California, recruited through convenience sampling. A total of 2572 students completed both surveys. Their outcomes were reported concern, worry, or stress regarding “increasing hostility and discrimination of people because of their race, ethnicity, sexual orientation/identity, immigrant status, religion, or disability status in society.” They found that each 1-SD increase on the societal discrimination concern composite in 2016 was associated with more days of past-month cigarette (incidence rate ratio [IRR], 1.77; 95% CI, 1.42-2.20; P < .001), marijuana (IRR, 1.13; 95% CI, 1.01-1.26; P = .03), and alcohol (IRR, 1.11; 95% CI, 1.02-1.21; P = .01) use; more substances used (IRR, 1.07; 95% CI, 1.01-1.17; P = .04); and greater odds of depression (odds ratio, 1.11; 95% CI, 1.01-1.23; P = .04) and attention-deficit/hyperactivity disorder (odds ratio, 1.12; 95% CI, 1.01-1.26; P = .04) symptoms in 2017.
