Rural-urban Disparities in the Nutritional Status of Younger Adolescents in Tanzania.

17. november 2020 opdateret af: Lorraine Cordeiro, University of Massachusetts, Amherst
Africa faces rapid urbanization, has the second highest population growth rate, makes up one-fifth of the world's youth population, and experiences stagnant rates of undernutrition. These challenges point to the need for country-specific data on rural-urban health disparities to inform development policies. This cross-sectional study examined disparities in body mass index-for-age-and-sex (BAZ) and height-for-age-and-sex z-scores (HAZ) among 1125 adolescents in Tanzania. Rural-urban disparities in nutritional status were significant and gendered. Findings confirm place of residence as a key determinant of BAZ, HAZ, and stunting among adolescents in Tanzania. Targeted gender-sensitive interventions among adolescents, particularly in rural areas, are needed to limit growth faltering and improve health outcomes.

Detaljeret beskrivelse

Africa faces rapid urbanization, has the second highest population growth rate, makes up one-fifth of the world's youth population, and experiences stagnant rates of undernutrition. These challenges point to the need for country-specific data on rural-urban health disparities to inform development policies. This cross-sectional study examined disparities in body mass index-for-age-and-sex (BAZ) and height-for-age-and-sex z-scores (HAZ) among 1125 adolescents in Tanzania. Pearson's chi-square tested associations between rural/urban residence and undernutrition (BAZ <-2SD), stunting (HAZ <-2SD), anthropometric, socioeconomic, and health indicators. Multivariate linear regression identified predictors of BAZ and HAZ.

Studiebefolkning

This cross-sectional study merged and analyzed two independent samples of adolescents living in Tanzania. One study was conducted in Tanzania by Cordeiro et al. (2012) and the other was conducted in an urban setting by Carlson, Brennan, and Earls (2012); both conducted in 2004. The Kilosa/rural dataset was derived from a two-stage sampling plan for selection of villages and adolescents. The Moshi/urban dataset was derived from a two-stage sampling plan for a cluster randomized control trial (CRCT). From a total combined sample of 1476 adolescents aged 10-19 years across both datasets, 1237 met the age criterion for younger adolescents (10-14 years). The analytical sample for this study was 1125.
