Prevalence of Obesity in Elementary Schoolchildren Living in Northeast Attica, Greece

OBJECTIVE: To assess the prevalence of obesity and obesity trend in schoolchildren living in Northeast Attica, Greece. RESEARCH METHODS AND PROCEDURES: Mean (standard deviation) and median weight and BMI were calculated in 4131 (2054 boys and 2077 girls) 6- to 11-year-old Greek schoolchildren living in Northeast Attica between November 2003 and April 2004. Two hundred thirty-six (95 boys, 141 girls) immigrant children also participated in the study. The secular trend for obesity was determined comparing our data with those of a similar study performed in 1994. RESULTS: Of boys, 27.8% were overweight, and 12.3% were obese. For girls, the corresponding values were 26.5% for overweight and 9.9% for obesity. There was an increase in the prevalence of overweight and obesity in the last 10 years in both sexes. For boys, overweight increased by 4.2% and obesity by 2.9%, whereas, for girls, overweight increased by 3.8% and obesity by 1.6%. Overweight and obesity were less prevalent in the immigrant children compared with their Greek peers. For immigrant boys, overweight was 15.9% and obesity was 7.9%, and for immigrant girls, overweight was 15.2% and obesity was 8.7%. DISCUSSION: Greek schoolchildren living in Northeast Attica present a high prevalence of overweight and obesity and a positive secular change in the prevalence of obesity.
