Obesogenic Environment in Childhood: Implications of High Socioeconomic Level in a Developing Country

Today, obesity in childhood is considered as an important health problem, especially in developed countries. This study aims to determine the prevalence of obesity in children and to reveal the relationship between television watching habit, computer use and socioeconomic status in children.

A cross-sectional study was performed in 11 public schools selected with random sampling in Istanbul. A total of 1479 children (767 males (51.9%)) were included in the study. Their ages ranged from 10-15, and the mean age was 11.95±1.36 years for girls and 12.06±1.39 years for boys. Demographic characteristics and factors affecting obesity were inquired with the structured questionnaire form.The height, and body weights of the students were measured, and their body mass ındexes were calculated. Those with a BMI above the 95th percentile were considered obese, and those between the 85^th and 95^th percentiles were considered as overweight.

In the study group, the obesity rate was calculated as 5.3%, and the mild obesity rate as 14.9 percent. The total prevalence of overweight and obese children was 20.2%. The frequency of obesity in the high socioeconomic level group was significantly higher than low one (p<0.01). The average daily screen time was 3.74±1.58 hours. The obesity risk was found to increase three times when this period exceeded five hours. In the logistic regression analysis, while high socioeconomic level was found as the main determinant among the risk factors for obesity, the effects of daily screen time were found to be marginally significant (p<0.045).

The lifestyle of the families with high socioeconomic status is the main determinant of obesity in adolescents. Nutrition with higher calorie foods, more frequent media use and a more sedentary life brought about is an obesogenic environment created by a high socioeconomic status. Environmental risk factors for obesity should be assessed.
