RESUMO
INTRODUCTION: With adolescent health a priority on the WHO agenda, research into the diet, weight status and metabolic profile of adolescents is indicated. The present study aimed to assess the diet and metabolic parameters of a rural sample of adolescents. METHODS: One hundred adolescents (17 years of age) were recruited from schools in Nea Madytos, Thessaloniki, Greece. Two previous-day food recalls were collected for each participant, and weight, height, waist circumference, serum lipids and fasting glucose levels were measured. The prevalence of underweight/overweight, central obesity, dyslipidemia and impaired fasting glucose (IFG) were calculated. RESULTS: Overweight was present in half the boys (51.2%) and one-fifth of the girls (21.3%). In the total sample 7.1% were underweight and another 7.1% were diagnosed with central obesity. Boys had an increased risk of abdominal obesity (OR:1.405, CI:0.7-2.8), IFG (OR:1.200, CI:0.3-4.9) and elevated triglycerides (OR:1.514, CI:1.0-2.4) and serum cholesterol levels (OR:1.806, CI:1.1-3.1). Central obesity increased the chances of IFG (OR:8.000, CI:1.6-39.1) and doubled the prevalence of dyslipidemia (OR:2.190, CI:0.5-9.1). Under-reporting of energy was found among overweight participants and was further verified by an inverse relationship between BMI and the ratio of energy intake to energy expenditure. Adolescents identified a dietary pattern high in fats in lieu of protein. CONCLUSIONS: Irrespectively of their weight status, teenagers consume a high fat diet; therefore, dietary counseling, as a means of preventive medicine, should be applied to all weight categories. In addition, the prevalence of obesity in a rural sample of adolescents appears to be higher compared with the whole of Greece.
