Prevalence of overweight and obesity in primary school children in Port Said city

Abstract

BackgroundThe highest prevalence rates of childhood obesity have been observed in developed countries, however, its prevalence is increasing in developing countries as well. ObjectivesTo estimate the prevalence of overweight and obesity among primary school children, aged from 6 to 12years and to estimate risk factors of obesity and overweight, defined by body mass index (BMI). MethodsA cross-sectional study was carried out at Port Said city during the second term of school year 2010/2011. The researcher took the anthropometric measurements inside the nurse’s room in the school and gave a questionnaire to the students to be answered by one of the child’s parents. The questionnaire included questions related to socioeconomic status, life style (physical activity and eating habits) and family history of overweight and obesity. ResultsEight hundred and fifty-two students participated in this study. Prevalence of overweight and obesity was 17.7% and 13.5% respectively. The rate of obesity was the highest at the age of 7–8years (grade 2) and decreased with an increase in age, while overweight increased with an increase in age to be the highest at the age of 9–10 (grade 4) and 10–11 (grade 5). Socioeconomic class, faulty dietary habits, sedentary life, low level of physical activity and positive family history of overweight and/or obesity were significantly associated with student’s BMI. ConclusionThis study found a relatively high prevalence of overweight and obesity among children aged 6–12years in Port Said city. Decreased rate of obesity with an increase in age in our study, signifies that faulty feeding habits were the highest at lower ages.
