This study examined the association between the obesogenic factors and the risk of suffering from weight excess in school-based state programs regarding physical activity, physical education, nutrition standards, and nutrition education in preventing childhood obesity. Data were drawn from the 1999-2011 Youth Risk Behavior Survey in the State of Mississippi (N = 8862; grades 9-12). Logistic regression with year-fixed effects was performed to capture the influence of the legislation on teenage obesity, controlling for demographics and nutrition- and physical activity-related behaviors. The age-, sex-, and ethnicity-adjusted mean of the body mass index had reduced since 2007 (year 1999: 23.52; year 2001: 23.53; year 2003: 23.76; year 2007: 24.26; year 2009: 24.29; and year 2011: 23.91). The legislation was significantly associated with a decreased likelihood of being overweight (year 2007, odds ratio (OR) = 0.686; year 2009, OR = 0.739; and year 2011, OR = 0.760; all < 0.01). Children who were more sedentary, more frequently fasted to lose weight, and were less physically active and likelier to be overweight (OR = 1.05, 1.37, and 0.97, respectively; all < 0.05), as were African-American children (OR = 0.64; < 0.05) and female students (OR = 1.59; < 0.05). In conclusion, schools are among the most easily modifiable settings for preventing childhood obesity and reducing its prevalence, with the implementation of physical activity and nutritional policies.
这项研究考察了肥胖因素与超重风险之间的关联，研究对象为参与州立项目的学生，这些项目涵盖了体育活动、体育教育、营养标准和营养教育等方面，目的是预防儿童肥胖。数据来自密西西比州 1999-2011 年的青年风险行为调查（N=8862；9-12 年级）。采用具有年份固定效应的逻辑回归来捕捉立法对青少年肥胖的影响，同时控制人口统计学、营养和体育活动相关行为的影响。自 2007 年以来，（年龄、性别和种族）调整后的 BMI 平均值有所下降（1999 年：23.52；2001 年：23.53；2003 年：23.76；2007 年：24.26；2009 年：24.29；2011 年：23.91）。立法与超重可能性降低显著相关（2007 年，比值比（OR）=0.686；2009 年，OR=0.739；2011 年，OR=0.760；均<0.01）。更久坐、更频繁禁食减肥、更缺乏体育活动且更可能超重的儿童（OR=1.05、1.37 和 0.97，均<0.05），以及非裔美国儿童（OR=0.64；<0.05）和女学生（OR=1.59；<0.05）也是如此。总之，学校是预防儿童肥胖和降低其流行率的最易改变的环境之一，通过实施体育活动和营养政策。
