Overweight and obesity in children and adolescents of Corrientes city.: Relationship with cardiovascular risk factors.

The prevalence of children's obesity is increasing all over the world. It has been related to an increment of all morbimortality causes in the mature age. To determine the prevalence of obesity and other cardiovascular risk factors in adolescence, and correlate them with each other, we designed a cross-sectional study. A survey was applied to 2115 secondary school students, 1212 (57.3%) females and 903 (42.7%) mates; blood pressure (BP) and cholesterol level were measured. Mean age: 14.8 +/- 1.6.: Body Mass Index (BMI): 20.6 +/- 3.1, 1838 (86.9%) normal, 230 (10.9%) where overweight and 47 (2.2%) obese, higher in males (OR=1.46; IC=1.12-1.91; p=0.03). Weekly physical activity: 3.9 +/- 2.9 hs. higher in males (p <0.001). Sedentarism daily hours: 3.2 +/- 1.9. Antecedents: maternal obesity 282 (13.3%), paternal 311 (14.7%) and in both 116 (6.6%). Regular consumption of fatty foods 1711 (80.9%). SEP: 107.8 +/- 13.6; DBP: 66.9 +/- 11.5; MBP: 80.5 +/- 10.1. We found hypertension in 64 (3%) prevalent in males (p=0.002). Cholesterol: 161.9 +/- 29.2; desirable 1283 (60.7%); normal high 628 (29.5%) and high 208 (9.8%). BML and MBP correlation was: r=0.25; r2=0.06; GI 95%: 0.02 - 0.11; b coefficient 0.83. We found a positive correlation of BMI with MBP (0.83 mm Hg increment for each point of BMI increment). We found significant association between parental obesity and alcohol consumption and BM[ increment. We did not find any association with dietary habits, physical activity or sedentarism.
