Background
Despite the continued effort to address malnutrition, there is a minimal reduction in the rate of stunting in developing countries including Ethiopia. Nutritional and socioeconomic factors have not been assed using a rigorous analysis so far. Therefore, this study aims to model the effect of nutritional and socioeconomic predictors using 2016 Ethiopian Demographic health survey.
Methods
This study is a secondary of data analysis of the 2016 EDHS survey. 7909 children of age 6-59 months were included. Descriptive statistics using frequency and percentage for categorical data and mean and standard deviation for metric data were conducted. Linearity, confounding and multicolinearity were checked. Bivariable and multivariable logistic regression were carried out. Odds ratio and 95% confidence interval were calculated. Receiver operative curve was built to estimate the sensitivity and specificity of the model.
Result
The study identified as 39.2% of children included to this analysis were stunted. 76.47%, 84.27%, 92.62% of the children did not consume fruits and vegetables, legumes and lentils, and meat and its products respectively. Children aged 24 month to 59 months were at 9.71 times higher risk of being stunted compared to younger children of age 6-24 months old (AOR: 9.71; CI: 8.07, 11.6 children) with weights below 9.1 kilogram were at 27.86 odds of being stunted compared to those weight of 23.3 kg and above. Moreover, mothers below 150 cm tall (AOR: 2.01; CI: 1.76, 2.5), living in a rural area (AOR: 1.3, CI: 1.09, 1.54) and being male (AOR: 1.4; CI: 1.26, 1.56) were associated with stunting. Predictive ability of the model was 77% correctly such pair of observation.
Conclusion
The model indicates that being born male, being from a mother of short stature, living in the rural area, small child size, mother with mild anemia, being from a husband with no education or primary education only, having low weight, and reaching age above 24 months increases the likelihood of stunting. On the other hand, being born of an overweight or obese mother decreases the likelihood of stunting.
