The aim of this study was to analyze the association between risk behaviors and adiposity indicators in adolescents and to discuss some methodological aspects related to this relationship. We evaluated 1,321 adolescents (55.2% female) aged 10-16 years. Relative body fat (%fat) by measurement of triceps and subscapular skinfold thickness and waist circumference (WC) were used as total and central adiposity indicators, respectively. Physical inactivity, time spent in front of the TV, the consumption of soda and/or chocolate, alcohol, and tobacco smoking were analyzed as risk behaviors. Information about the socioeconomic status (categorized into three levels) and nutritional status of the mother (overweight or normal weight) were used as adjustment factors in the analyses of prevalence ratio (PR) of the outcomes and their associated 95% confidence intervals (95% CI). The chi-square test and Poisson regression were used for statistical analyses. Low associations were found between risk behaviors and adiposity indicators. Tobacco smoking was the most positively correlated behavior with adiposity in girls (%fat: PR = 1.61; 95% CI = 1.04-2.47; WC: PR = 1.90; 95% CI = 1.17-3.08) and in adolescents whose mothers were normal weight (%fat: PR = 2.31; 95% CI = 1.33-4.03; WC: PR: 2.31; CI: 1.19-4.46). Additionally, as an important methodological issue, we highlighted the assessment of risk behaviors in adolescents as crucial to producing more robust evidence on the subject. Of the investigated behaviors, we concluded that tobacco smoking is the behavior most associated with adiposity indicators.
本研究的目的是分析青少年风险行为与肥胖指标之间的关联，并探讨与这种关系相关的一些方法学方面的问题。我们评估了1321名年龄在10至16岁之间的青少年（女性占55.2%）。通过测量肱三头肌和肩胛下皮褶厚度得出的相对体脂（%fat）以及腰围（WC）分别用作总体肥胖指标和中心性肥胖指标。将身体活动不足、看电视的时间、汽水和/或巧克力的摄入量、饮酒以及吸烟作为风险行为进行分析。在分析结果的患病率比（PR）及其相关的95%置信区间（95%CI）时，将社会经济状况（分为三个等级）和母亲的营养状况（超重或正常体重）信息用作调整因素。采用卡方检验和泊松回归进行统计分析。发现风险行为与肥胖指标之间的关联较低。吸烟是与女孩肥胖相关性最强的行为（%fat：PR = 1.61；95%CI = 1.04 - 2.47；WC：PR = 1.90；95%CI = 1.17 - 3.08），在母亲体重正常的青少年中也是如此（%fat：PR = 2.31；95%CI = 1.33 - 4.03；WC：PR：2.31；CI：1.19 - 4.46）。此外，作为一个重要的方法学问题，我们强调对青少年风险行为的评估对于就该主题产生更有力的证据至关重要。在所有调查的行为中，我们得出结论，吸烟是与肥胖指标关联最密切的行为。
