Abstract


 

 Background: Hypertension (HTN) in children and adolescents is also a major health problem that is overlooked by physicians. It is well-established that overweight and childhood obesity are in strong correlation with primary HTN in children. Hence, history and physical examination on regular bases is needed for all children with HTN with or without obesity to rule out underlying secondary causes. Objective: The objective of the study was to estimate the prevalence of HTN among obese and overweight children aged 10–18 years. Methodology: A cross-sectional comparative study was done in ten schools of Miraj city by Systematic sampling among overweight and obese children aged 10–18 years for a period of 1 year. Overweight is defined as body mass index (BMI) >85th percentile, and obese (BMI >95th percentile) children. Children with congenital heart diseases, k/c/o cardiac disease, and taking medications which affect cardiac function were excluded from the study. A total sample size of 180 subjects was included and was evaluated for HTN. Results: In our study, 66.7% were overweight and 33.3% were obese. The prevalence of HTN in overweight and obese children is 7.8%. Among 14 subjects with HTN, 14.3% were overweight and 85.7% were obese. In our study, among those with overweight, 1.7% had HTN and among obese subjects, and 20% had HTN. There was significant difference in the prevalence of HTN between overweight and obese subjects. In our study, among hypertensive children, 85.7% were females and 14.3% were males. Among normotensive subjects, 54.2% were females and 45.8% were males. Conclusion: From our study, it can be concluded that overweight and obesity are important risk factors for HTN among children aged b/w 10–18 years. With increase in weight, prevalence of HTN was also increased among children. Females had higher prevalence of obesity and HTN in the present study.
