Risk factors of stunting (chronic undernutrition) of children aged 6 to 24 months in Mekelle City, Tigray Region, North Ethiopia: An unmatched case-control study

In 2014, 159 million under 5 year-old children were stunted (suffered chronic undernutrition) worldwide. Identifying risk factors for stunting among 6 to 24 month-age children in Mekelle City is important for evidence-based interventions. Case-Control study design was undertaken in 330 children, from January to February 2016. World Health Organization (WHO) anthropometric software and statistical package for social sciences version 20 were used for analysis. Logistic regression analysis was applied. The following were identified as risk factors for stunting: mother's lack of formal education (adjusted odds ratio (AOR = 6.4)), mother height less than 150cm (AOR = 4.2), mother with a body mass index less than 18.5 kg/m2 (AOR = 3.8), childbirth weight less than 2.5kg (AOR = 5.3), household with two and above under-five children (AOR = 2.9), a WHO diet diversity score < 4 (AOR = 3.2) and repeated diarrheal episodes (AOR = 5.3). The factors associated with stunting among children aged 6 to 24 months are no formal education in mother, mother height less than 150cm, low BMI of the mother, low birth weight, low WHO DDS, number of under 5 children in the household and repeated diarrheal episodes. Nutritional interventions should give emphasis to maternal education, maternal nutrition, childbirth weight, family size, diet diversity, and diarrheal diseases.
