Prevalence and associated factors of stunting and thinness among adolescent students in Finote Selam Town, Northwest Ethiopia

Background Undernutrition among adolescents is a major public health problem in developing nations including Ethiopia. Adolescents need to have good-quantity and good-quality nutrients to cope with this rapid growth and other health risks which increase nutritional demand. This study aimed to assess the prevalence and associated factors of stunting and thinness among school adolescents in Finote Selam Town, Northwest Ethiopia. Methods A school-based cross-sectional study among adolescent students aged 10-19 in public schools was carried out in Finote Selam Town from February 5 to March 27, 2018. A total of 397 school adolescents were included in this study. Stratified and simple random sampling techniques were employed to select study subjects. Pretested structured questionnaires were used to collect the data. Data were entered using Epi info version 7 and analyzed using SPSS version 20 and WHO AnthroPlus software. A multivariable logistic regression analysis was employed to identify factors associated with stunting and thinness. Crude and adjusted odds ratios with 95% level significance were used to measure the strength of association, and statistical significance was declared at a P value less than 0.05. Results The prevalence of stunting and thinness among school adolescents was 21.8% and 16.9%, respectively. About 9.7% of school adolescents experienced both stunting and thinness. Being male (P = 0.031), coming from rural area (P = 0.046), having a family monthly income of less than $28.37 (P = 0.044) and having less than four dietary diversity (P = 0.021) were significantly associated with stunting. Early adolescent stage (P = 0.034), being male adolescent students (P = 0.37), having a family monthly income of less than $28.37 (P = 0.016), having a family monthly income between $28.37 and $56.74 (P = 0.021) (35.25 Birr = 1 USD) and using well water (P = 0.045) were significantly associated with thinness. Conclusion Undernutrition was a predominant problem in the study area. Sex, age, place of residence, dietary diversity, sources of drinking water and family monthly income were important factors associated with stunting and thinness among the respondents. Strategies to improve the nutritional status of adolescent students should be given much attention.
