Childhood and adolescent obesity is an ongoing problem in the Western World and has increased dramatically over the last four decades. Similar trends have been observed in Israel, but only limited data has been available on the prevalence of obesity. The rise in the prevalence of childhood obesity is mainly attributed to the change in lifestyle including increased intake of fast food and lowered extent of physical activities.To determine the current prevalence of childhood and adolescent obesity in Northern Israel and to compare results to former years.We conducted an analysis of weight, height and body mass index (BMI, in two separate periods: between the years 2010-2012 and 2005-2007, using the electronic medical records of the Clalit Health Services. A total of 94,239 subjects were enrolled between the ages of 2-18 years.Twenty four percent of the children had a BMI above the 85th centile and 10.5% were found to be obese. The prevalence of obesity was higher in males as compared to females [11.5% vs. 9.5%, respectively, p0.0001). Obesity peaked in girls at age 9 and in boys at age 11 (33%, 30.5%, respectively). The prevalence of overweight and obesity was significantly higher in urban regions when compared with rural regions in all age groups. Among the age groups of 2-5 and 6-11 years, the Jewish population showed a higher rate of overweight and obesity as compared to the Arab population (age group 2-5 years: obesity 9.6% vs. 8.3%, respectively, p=0.15; above 85th centile: 22.2% vs. 19.6%, respectively, p0.0001; age group 6-11 years: obesity 12.9% vs. 10.5%, respectively, p0.0001; above 85th centile: 26.5% vs. 23.4%, respectively, p0.0001). No increase in the prevalence of obesity was observed between the years 2005-2007 and 2010- 2012 and above the age of 6 years a trend towards a decrease in the prevalence of obesity and overweight has been shown.A high prevalence of overweight and obesity has been shown in northern Israel. The prevalence was high for all age groups. The finding that there was no increase in the prevalence of obesity during the last 5 years may suggest that obesity has reached its peak. |
