Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Body Mass Index for age and gender z-scores	Weight (Kg)/Height (M) squared compared to the WHO growth reference standard	Two measures collected consequentially during a 30 minute time frame on the date of survey administration.
Primary	Height for age and gender z-scores	Height in meters for age and gender compared to the WHO growth reference standard	Two measures collected consequentially during a 30 minute time frame on the date of survey administration.
Primary	Undernutrition	Body Mass Index for age and gender z-scores < -2SD of the WHO growth reference standard	Height and weight measures collected twice consequentially during a 30 minute time frame on the date of survey administration.
Primary	Stunting	Height (M) for age and gender z-scores < -2SD of the WHO growth reference	Two measures of height in meters collected consequentially during a 30 minute time frame on the date of survey administration.
