Abstract

Seasonal variation in nutritional status is a concern in sub-Saharan Africa. Seasonality in the food consumption of young Tanzanian children has a substantial and negative impact on later life outcomes. Seasonal variation in adult nutritional status has implications for labor productivity and prenatal health. Just as mean poverty status or mean health status varies within households, seasonal patterns in health status are likely to vary within households, as well as the mechanisms underlying seasonal variation. We parameterize and compare seasonality in nutritional status across multiple types of household members in rural, farming households in Tanzania, using a novel anthropometric measure of body mass index z-score that is comparable across adults and children. Young children not yet in school and working adults are most vulnerable to seasonal fluctuations in nutritional status. Children in school and older adults are relatively shielded. Seasonal variation in the nutritional status of working adults can be partly explained by variation in dietary quality and agricultural labor hours. Seasonal variation in the nutritional status of young children is not explained by either factor, nor is it mitigated by market access. Our results suggest we do not understand the data generating process behind seasonality in the nutritional status of young children, despite the critical implications of this seasonality for development and later life productivity.
