Prevalence of obesity and hypertension in children and determination of associated factors by CHAID analysis

Abstract

BackgroundThe prevalence of obesity and hypertension in children is associated with an increased risk of cardiovascular disease and increases the prevalence of heart failure and associated morbidity and mortality. This study aimed to determine the prevalence of obesity and hypertension, as well as the associated risk factors, in school-age children. MethodsThis cross-sectional study was conducted in 21 schools in Antalya, Turkey. A total of 5160 students between the ages of 5 and 15 years participated in the study. The data were collected using a questionnaire, and students’ height, weight, and blood pressure were measured. The data were evaluated using numbers, percentages, mean, and chi-squared automatic interaction detector (CHAID) analysis. ResultsIn all, 11.4% of children were overweight, 11.8% were obese, 6.8% had prehypertension, and 5.7% had hypertension. School level, school location, and father's educational status were determined as factors associated with overweight and obesity; BMI, school level, school location, and mother's working status were determined as factors related to hypertension in the children. ConclusionThe prevalence of hypertension, overweight, and obesity was found to be significantly high in the children, especially those living in rural areas. Therefore, it is recommended that these health issues be monitored in children and that necessary measures be taken by considering regional differences.
