Undernutrition and Associated Factors among Adolescent Girls in Damot Sore District, Southern Ethiopia

Abstract

Background. Adolescent girls were given little health and nutrition attention. Focusing on adolescent girls’ nutrition prior to conception is one way to break the intergenerational cycle of malnutrition. Therefore, the aim of this study was to assess the prevalence of undernutrition and associated factors among adolescent girls in rural Damot Sore District, Southern Ethiopia. Methods. A community-based cross-sectional study was conducted from February to March 2017. Multistage sampling technique was used to select 729 adolescent girls. Structured interviewer-administered questionnaire was used to collect information on different variables. Weight and height were measured by using a well-calibrated digital Seca scale and portable stadiometer by trained data collectors. Height-for-age (HFA) and body mass index-for-age (BMIFA) z-scores were calculated using WHO AnthroPlus software as indicators of stunting and thinness, respectively. Wealth index was generated by using principal component analysis (PCA), and based on the results, household wealth index/status was converted into tertiles and categorized as higher/rich, medium, and lower/poor. Descriptive statistics, bivariable, and multivariable logistic regression analysis were done. Strength of association of variables was presented by odds ratio along with its 95% CI. Results. The prevalence of stunting and thinness among adolescent girls was 29.6% (95% CI = 26.6%, 32.8%) and 19.5% (95% CI = 16.7%, 22.3%), respectively. Being in older adolescence (AOR = 2.06, 95% CI = 1.08, 3.92), mother occupation (farmer and government employee) ((AOR = 2.38, 95% CI = 1.31, 4.33) and (AOR = 3.05, 95% CI = 1.35, 6.92)), mother education (secondary and above) ((AOR = 0.53, 95% CI = 0.28, 0.98) and (AOR = 0.25, 95% CI = 0.09, 0.69)), and household wealth index (poor) (AOR = 1.94, 95% CI = 1.29, 2.92) were significantly associated with stunting. Father education (primary and secondary) ((AOR = 0.48, 95% CI = 0.31, 0.77) and (AOR = 0.45, 95% CI = 0.26, 0.78)), mother education (primary) (AOR = 0.56, 95% CI = 0.37, 0.87), and meal frequency (<2/day) (AOR = 1.87, 95% CI = 1.12, 3.13) were significantly associated with thinness. Conclusion. The prevalence of stunting and thinness among adolescent girls was moderate, when compared to the prevalence reported in Sub-Saharan Africa. However, it was a major public health problem, when compared to the national nutrition baseline survey reports in Ethiopia. Parental education was a significant predictor of both stunting and thinness among adolescent girls. Thus, initiation of routine screening, promotion of education, and implementation of evidence based community nutrition programmes required to be improved.
