Given the high collinearity between independent variables such as types of soil, roofing and walls, only the type of soil was taken into account in the model. And for nutritional status because of the multicollinearity between stunting, wasting and underweight, only wasting is included in the model
The odds ratio (OR) with a corresponding 95% confidence interval was reported to quantify the strength of association. Bold values indicate statistically significant p values (p < 0.05)
