Factors Associated With Stunting Among Infants and Young Children Aged 7–29 Months in Post-conflict Northern Uganda

Abstract Objectives To examine factors associated with stunting in Agago District, Uganda Methods We used cross-sectional data from a quantitative baseline survey of 870 households of the ONCE (One Nutrition in Complex Environments) project currently being conducted in Agago district of Uganda. Survey data used include infant anthropometry, infant feeding practices, 24-hour dietary recall, maternal heights, weights, education and household characteristics. Statistical methods include Pearson correlation coefficients, student T-tests, pair-wise mean comparisons with Bonferroni adjustment, and stepwise multivariable linear and logistic regression analyses controlled for clustering. Dependent variables include length-for-age z-score (LAZ, −6 to 6, continuous) and being stunted (binary). Independent variables include child age, child's birth weight, diarrheal morbidity (past two weeks), maternal education, maternal height, household wealth index, and animal sourced foods consumption (ASF, categorical: no ASF (comparator), 1 ASF, >= 2 ASF). ASF is defined as consumption of dairy, animal flesh, fish of any kind, organ meat, insects, or eggs in previous 24 hours. Results Infants between 7 months and 2.5 years with complete data were included (N = 621), of whom 19.7% were classified as stunted. Mean LAZ was −1.05 (SD: 1.24). Most children did not consume any ASF in the past 24 hours (73.6%). ASF consumption was not associated with LAZ (1 kind of ASF: −0.0699, 95% CI: −0.329, 0.189) or stunting (1 kind of ASF OR: 1.186, 95% CI: 0.614, 2.292). Maternal height was associated with 7.8% decreased odds of being stunted (OR: 0.922, 95% CI: 0.878, 0.969); age was associated with 8.9% increased odds of being stunted (OR: 1.089, 95% CI: 1.011, 1.090); birth weight was associated with 54% decreased odds of being stunted (OR: 0.461, 95% CI: 0.296, 0.717). Infants with diarrhea were 96% more likely to be stunted than those without (OR: 1.956, 95% CI: 1.050, 3.642). Conclusions Factors associated with stunting were maternal height, child age, birth weight and diarrheal morbidity. ASF consumption was not, possibly due to low levels and possibly low frequency of consumption. Mother's nutritional status is likely to be an important predictor in this population.
