The purpose of this study was to examine the relationships among physical activity, sleep duration, diet, and academic achievement in a sample of adolescents from the US state of Nevada. A two-stage cluster random sampling method was used to recruit Nevadan adolescents (N = 4625). The 2015 Youth Risk Behavior Survey was administered to students within public, private, and charter schools. Weighted multilevel generalized linear mixed effects models were employed to examine the relationships among physical activity, sleep duration, diet, and academic achievement. Additional analyses were run to examine the relationship between meeting multiple health behavior criteria with academic achievement. Data were collected in the US state of Nevada in 2015 and analyzed in the US state of Nevada in 2018. Adolescents who participated in at least of 60 min of physical activity per day had significantly higher odds of achieving mostly A's and B's (adjusted OR = 1.18; 95% C.I.: 1.02, 1.38; p = 0.029). Additionally, adolescents who consumed salad weekly (adjusted OR = 1.24; 95% C.I.: 1.06, 1.46; p = 0.007) and who consumed breakfast everyday (adjusted OR = 1.72; 95% C.I.: 1.48, 2.00; p < 0.001) had higher odds of achieving mostly A's and B's. Finally, adolescents who reported meeting 3 or more health behavior criteria had significantly higher odds of achieving mostly A's and B's compared to adolescents meeting only 0-2 health behaviors (adjusted OR = 1.66; 95% C.I.: 1.44, 1.92; p < 0.001). Self-reported physical activity, specific dietary behaviors, and meeting multiple health behavior criteria significantly related to academic achievement in adolescents.
本研究的目的是调查美国内华达州青少年样本中身体活动、睡眠时间、饮食与学业成绩之间的关系。采用两阶段整群随机抽样方法招募内华达州青少年（N = 4625）。对公立、私立和特许学校的学生进行了2015年青少年风险行为调查。采用加权多级广义线性混合效应模型来研究身体活动、睡眠时间、饮食与学业成绩之间的关系。进行了额外分析以检验满足多种健康行为标准与学业成绩之间的关系。数据于2015年在美国内华达州收集，并于2018年在美国内华达州进行分析。每天至少进行60分钟身体活动的青少年获得大多为A和B成绩的几率显著更高（调整后的比值比=1.18；95%置信区间：1.02，1.38；p = 0.029）。此外，每周食用沙拉的青少年（调整后的比值比=1.24；95%置信区间：1.06，1.46；p = 0.007）以及每天吃早餐的青少年（调整后的比值比=1.72；95%置信区间：1.48，2.00；p < 0.001）获得大多为A和B成绩的几率更高。最后，报告满足3项或更多健康行为标准的青少年与仅满足0 - 2项健康行为的青少年相比，获得大多为A和B成绩的几率显著更高（调整后的比值比=1.66；95%置信区间：1.44，1.92；p < 0.001）。自我报告的身体活动、特定饮食行为以及满足多种健康行为标准与青少年的学业成绩显著相关。
