Abstract
BACKGROUND
Cross-sectional surveys using the Standardized Monitoring and Assessment of Relief and Transitions methodology have been conducted annually in Chad since 2015 to evaluate population-level nutritional status.
OBJECTIVE
This analysis characterizes national and subnational trends in child wasting and women's thinness from 2015 to 2021 in Chad and identifies risk factors during the COVID-19 pandemic.
METHODS
Annual survey data with 12,000 to 15,000 households were included. Wasting was estimated for children 6 to 59 months using the WHO child growth standards, and among women 15 to 49 years, thinness was defined as mid-upper arm circumference <23 cm. Trends were stratified by agroecological zone, and chi-square tests used to assess statistical significance. Simple and multivariate logistic regression models were conducted for 2020 and 2021 to identify risk factors of wasting and thinness.
RESULTS
About 11,958 to 17,897 children and 9883 to 15,535 women contributed values each year. National wasting and thinness rates did not significantly decrease over the 7-year period (wasting: 14.1% to 12.1%, P = .43; thinness: 15.2% to 13.4%, P = .51) and wasting rose from 2020 to 2021. The Saharan and Sahelian zones had consistently higher rates compared to the Sudanian zone. Younger age, male sex, inadequate infant and young child feeding practices, and poorer household socio-economic factors were associated with greater odds of child wasting. For women, younger age, lack of nutrition knowledge, and poorer household socio-economic factors increased the odds of thinness.
CONCLUSIONS
Undernutrition in Chad has not improved since 2015, and the COVID-19 pandemic likely exacerbated the crisis among children nationally and among women subnationally. Multisectoral approaches and regional targeting of interventions are recommended.
