RESUMEN
PURPOSE: Child marriage is associated with multiple adverse health and social outcomes. Although evidence suggests that child marriage is associated with reduced participation in personal and household decisions for women, less is known about the association between age at marriage and decision-making among married adolescent girls. This study assesses associations between adolescents' age at marriage and two dimensions of decision-making (participation and satisfaction) in the high early marriage prevalence settings of Niger. METHODS: Cross-sectional data from a cluster-randomized control trial of a community-level program to increase the use of modern contraceptives among married adolescents in the Dosso region of Niger were analyzed. Multiple logistic regression models were used to determine the association of age at marriage with married girls' participation in and satisfaction with decision-making processes. RESULTS: More than half of married adolescents (N = 796) were married before reaching the age of 15 years. Older age at marriage was associated with adolescents' increased participation in decisions related to economics (adjusted odds ratio: 1.23; 95% confidence interval: 1.05-1.43) and health-care access (adjusted odds ratio: 1.18; 95% confidence interval: 1.01-1.40), but not with greater reported satisfaction with their control over these decisions. CONCLUSIONS: The study suggests that marrying as a very young adolescent places girls in even more disadvantaged positions regarding decision-making. These findings indicate the need to design programs targeted at addressing inequitable gender norms to reduce early child marriage and increase participation in decision-making. Further study of satisfaction with participation in decision-making is recommended, including consideration of whether it is related to gender norms for participation in decisions rather than actual participation.
