OBJECTIVE:
To verify the prevalence of obesity, systemic arterial hypertension (SAH), waist circumference and acanthosis nigricans (AN) in school children from Sorocaba, in 2009 and associate them with risk factors.METHODS:
A probabilistic sample study was carried out with 680 children (7-11 years) from 13 public schools from the city of Sorocaba, SP. A questionnaire containing questions on physical activity, time spent watching television, playing with videogames and computers (TV/VG/PC), student and parental antecedents of arterial hypertension, renal or cardiac disease, and economic level was applied. On physical examination, weight, height, waist circumference (WC) and blood pressure (BP) were measured; presence of AN was observed. The prevalence of nutritional disorders, SAH, WC increase and presence of AN were calculated. To associate body mass index (BMI) > P85 and BP > P90 with the other variables, chi square or Fisher's exact test (significance p < 0.05) and crude and adjusted prevalence odds ratio (POR) were used.RESULTS:
The prevalence of BMI > P85 was 22.1 percent [95 percent CI 19.0-25.3 percent], of BP > P90 10.9 percent [95 percent CI 8.6- 13.5 percent], increased WC 15.4 percent [95 percent CI 12.9-17.9 percent] and AN 3.8 percent [95 percent CI 2.6-5.6 percent]. Paternal antecedents were associated with weight excess in both analysis (POR 1.76; 95 percent CI 1.05-2.95; p = 0.02). High blood pressure was associated with female sex (POR 1.90; 95 percent CI 1.12-3.23; p = 0.01), more time spent with TV/VG/PC (POR 1.82; 95 percent CI 1.00-3.36; p = 0.03), AN (POR 8.18; 95 percent CI 3.37-19.80; p < 0.00), obesity (POR 4.09; 95 percent CI 2.41-6.94; p < 0.00) and WC (POR 4.83; 95 percent CI 2.77-8.41; p < 0.00). After the multivariate analysis, the female sex (adjusted POR = 2.15; 95 percent CI 1.17-3.93) and obesity (adjusted POR = 9.51; 95 percent CI 4.77-18.97) remained.CONCLUSION:
The prevalence of weight excess, SAH, increased WC and AN in these school children was relevant. This fact justifies the use of these measurements.
