Contextual Variation in Early Adolescent Childbearing: A Multilevel Study From 33,822 Communities in 44 Low- and Middle-Income Countries.

Purpose: Existing literature calls for a deeper examination into how local context influences adolescent sexual and reproductive health outcomes. We seek to describe individual and contextual variation in early adolescent childbearing (younger than 16 years) in 44 low- and middle-income countries by (1) examining the role of individual-level social disadvantage, (2) exploring the ecological influence of context at the country and community level, and (3) assessing whether ecological effects vary according to a woman's wealth.

Methods: We used nationally representative data from 33,822 communities in 44 low- and middle-income countries. We employed multilevel modeling to examine the variation in early adolescent childbearing apportioned to the individual, community, and country levels.

Results: Globally, poverty and low educational attainment are associated with early adolescent childbearing. After accounting for individual-level characteristics, significant residual variance remains at both the community and country levels. Routine, individual-level covariates explain 46.4% of the total variance at the community level and 21.3% of the total variance at the country level in relation to the baseline, age-adjusted model. The variance apportioned to the community level is estimated to equal 43.5% (95% confidence interval: .40, .49) of the total variance among the poorest women compared with 32.6% (95% confidence interval: .25, .39) among the richest women. Across countries, we find substantial heterogeneity in the variance observed at the community level.

Conclusions: Our results point to the need for a continued focus on multilevel interventions that include approaches to target both the individual and population levels. More research is needed to identify the mechanisms through which local context influences adolescent sexual and reproductive health outcomes.
