OBJECTIVE: Suicide rates continue to rise, necessitating identification of novel risk factors to prevent suicide. Obesity and suicide mortality have been examined, but no studies have examined associations between weight change, suicide mortality, and depression among adults in the U.S. METHODS: People who died by suicide from 2000-2015 with a recorded height and weight in the first and second 6 months preceding their death (“index date”; n = 387) were extracted from a larger sample from the Mental Health Research Network; each was matched with five people in the control group by age, sex, index year, and healthcare site (n = 1,935). Data were analyzed in 2020. RESULTS: People who died by suicide were predominantly male (71%), Caucasian (69%), depressed (55%), middle aged (M = 57 years), with chronic health issues (57%), [Control: 66% Caucasian; M age = 56 years; 43% chronic health issues, 14% depressed]. T-test analyses showed BMI change within a year before the index date differed between those who died by suicide (M = −0.72±2.42 kg/m(2)) and the control group, (M = 0.06±4.99 kg/m(2)) p < 0.001, d = .17. A 1-unit decrease in BMI was associated with 9% increased risk of suicide after adjusting for demographics, mental disorders, and Charlson score (aOR = 0.91, 95% CI = 0.87-0.95, p < 0. 001). BMI change and suicide were associated for those without depression (p < 0.001). CONCLUSIONS: Weight loss in the year before suicide was associated with increased suicide mortality after accounting for physical and mental health indicators.
