Family structure and substance use in 6,178 American Indian youth: a cross-sectional study.

Abstract

Adolescents from single-parent families are at significantly higher risk of substance use compared to those from mother-father families. More than half of American Indian (AI) children live in single-parent families, the second highest percentage among all groups. Given the paucity of research pertaining to the role of family structure and substance use in the AI population, we sought to examine this relationship. Data from this study were obtained from the Substance Use Among American Indian Youth: Epidemiology and Etiology, [US], 2015-2020 study. Response variables of interest included age at first substance use, number of substances used, ever-use of substance, and substance use type (i.e., alcohol, cigarette, marijuana, etc.). Living in a father-only or mother-only setting showed a similar pattern of drug use. There was a significant increase in the risk of cigarette, alcohol and marijuana use. For cigarettes, the odds ratio was (OR = 2.60, 95% CI 1.80-3.75) in father-only setting compared to (OR = 1.42, 95% CI 1.13-1.78) for mother only setting. Alcohol use showed (OR = 1.72, 95% CI 1.19-2.50 and OR = 1.40, 95% CI 1.12-1.74) for father-only and mother-only respectively and marijuana use showed (OR = 1.59, 95% CI 1.10-2.30 and OR = 1.54, 95% CI -1.24-1.92) for father-only and mother-only respectively. Disturbed family structure is associated with increased risk of substance use among AI youth. This indicates the importance and need for policy and community level interventions to reduce youth substance exposure.
