This study sought to identify the prevalence of excess weight and food consumption patterns among adolescents attending public schools in northern Minas Gerais state. A cross-sectional study was conducted with a random and representative sample of adolescents. Demographic and economic data were collected. Food consumption was evaluated by applying a semi-quantitative food questionnaire. Body weight and height were measured to assess the nutritional status based on the Body Mass Index (BMI) by Age. The sexes were compared by Student's t test (comparison of samples) and chi-square test (goodness of fit) at a level of significance of p <0.05. 535 adolescents were evaluated and prevalence of excess weight was detected in 18.5% of the group. BMI (p = 0,001) was statistically different between the sexes and higher for girls. The average energy consumption of the group was 3096.30 kcal/day. Fiber consumption was insufficient in 35% of the adolescents, vitamin A and calcium in 80% and unsaturated fats in 100%. Carbohydrate and cholesterol were consumed in excess by 20.6% and 48%, respectively. The prevalence of excess weight and inadequate food consumption is of great concern for the population studied and requires appropriate nutritional intervention.
本研究旨在确定米纳斯吉拉斯州北部公立学校青少年中超重的患病率以及食物消费模式。对青少年进行了一项随机且具有代表性样本的横断面研究。收集了人口统计学和经济数据。通过应用半定量食物问卷来评估食物消费情况。测量体重和身高，根据年龄别体重指数（BMI）评估营养状况。采用学生t检验（样本比较）和卡方检验（拟合优度）对性别进行比较，显著性水平为p<0.05。对535名青少年进行了评估，该组中超重患病率为18.5%。BMI在性别之间存在统计学差异（p = 0.001），女孩的BMI更高。该组的平均能量消耗为3096.30千卡/天。35%的青少年纤维摄入量不足，80%的青少年维生素A和钙摄入量不足，100%的青少年不饱和脂肪摄入量不足。分别有20.6%和48%的青少年碳水化合物和胆固醇摄入过量。超重患病率和食物消费不足对所研究的人群而言是极大的担忧，需要进行适当的营养干预。
