We evaluate the influence of demographic, socioeconomic, and maternal variables on the nutritional status of adolescents aged 11 years. We conducted a prospective cohort study including 4,452 adolescents born in Pelotas, Southern Brazil, in 1993, accounting for 87.5% of the original cohort. Nutritional status was evaluated based on World Health Organization criteria. Subjects were classified according to nutritional status into thin, normal, overweight and obese. Independent variables analyzed included skin color, socioeconomic status, maternal schooling, and maternal body mass index (BMI). Analyses were stratified by sex, and multivariable regression was performed using the multinomial logistic approach. Overall, 7% of adolescents were classified as thin, 11.6% as overweight, and 11.6% as obese. Among boys, thinness was inversely associated with maternal schooling and maternal BMI. Among girls, thinness was directly associated with maternal BMI. Overweight and obesity were directly associated with socioeconomic status and maternal BMI, the former showing the strongest association with nutritional status among adolescents.
我们评估了人口统计学、社会经济和产妇变量对 11 岁青少年营养状况的影响。我们进行了一项前瞻性队列研究，纳入了 1993 年在巴西南部佩洛塔斯出生的 4452 名青少年，占原始队列的 87.5%。营养状况评估基于世界卫生组织的标准。根据营养状况，受试者被分为消瘦、正常、超重和肥胖。分析的自变量包括肤色、社会经济地位、母亲教育程度和母亲体重指数（BMI）。分析按性别分层，并使用多项逻辑回归方法进行多变量回归。总体而言，7%的青少年被归类为消瘦，11.6%为超重，11.6%为肥胖。在男孩中，消瘦与母亲教育程度和母亲 BMI 呈负相关。在女孩中，消瘦与母亲 BMI 呈正相关。超重和肥胖与社会经济地位和母亲 BMI 直接相关，前者与青少年的营养状况相关性最强。
