Prevalence and associated factors of stunting and thinness among primary school-aged children in Gudeya Bila district, West Ethiopia: a cross-sectional study

Objectives This study aimed to assess the prevalence and associated factors of stunting and thinness among primary school-age children in the Gudeya Bila district.Methods and analysis A community-based cross-sectional study was conducted in the Gudeya Bila district which is located in the Western part of Ethiopia. Among the calculated sample size of 561 school-aged children, 551 children were randomly selected by systematic random sampling technique and participated in this study. Critical illness, physical disability and the inability of caregivers to respond were exclusion criteria. Under-nutrition was the primary outcome while factors associated were the second outcome of this study. Semi-structured interviewer-administered questionnaires were used to collect the data while interview and body measurement were used as data collection techniques. Health Extension Workers collected the data. Data were entered into Epi Data V.3.1 and transported into SPSS V.24.0 software for data cleaning and analysis. Both bivariable and multivariable logistic regressions were run to identify the associated factors of under-nutrition. Model fitness was checked by using Hosmer-Lemeshow's test. Variables with p values <0.05 were considered statistically significant in the multivariable logistic regression.Results and conclusion The prevalence of stunting and thinness among primary school children was 8.2% (95% CI 5.6% to 10.6%) and 7.1% (95% CI 4.5% to 8.9%), respectively. Being male caregiver (adjusted OR (AOR)=4.26;95% CI 1.256% to 14.464%), family size >= 4 (AOR=4.65; 95% CI 1.8 51% to 11.696%), separated kitchen room (AOR=0.096; 95% CI 0.019 to 0.501) and hand washing after toilet use (AOR=0.152; 95% CI 0.035% to 0.667%) were significantly associated with stunting. Moreover, drinking coffee (AOR=2.25; 95% CI 1.968% to 5.243%) and child dietary diversity score <4 (AOR=2.54; 95% CI 1.721% to 8.939%) were significantly associated with thinness. Under-nutrition in this study was high compared with the global target of eradicating under-nutrition. Community-based nutritional education programmes and implementing health extension programmes are important to reduce the problem of under-nutrition to an undetectable level and to eradicate chronic under-nutrition.
