Abstract
Background: There is a paucity of literature regarding income inequality and adolescent movement behaviours (physical activity, sedentary behaviours, sleep). This study examined whether income inequality was associated with meeting Canadian 24-Hour Movement Guidelines (24HMG) recommendations among adolescents over time.
Methods: Longitudinal data from adolescents (n=9299) in the Cannabis, Obesity, Mental health, Physical activity, Sedentary behaviour and Smoking study (2016-2017 to 2018-2019) were linked with income data at the census division (CD) level from the 2016 Canadian Census. Adolescents (aged 13-19 years) reported on their physical activity, sleep duration and screen time via questionnaire. Gini coefficients were calculated at the CD level using after-tax household income from the 2016 Canadian Census. Multilevel logistic regression analyses were performed to test the association between income inequality and meeting several 24HMG recommendations.
Results: The joint effect (income inequality*time) was significant for meeting the sleep duration recommendation (2017-2018 OR=0.83, 95% CI 0.74, 0.92; 2018-2019 OR=0.77, 95% CI 0.70, 0.86; p<0.0001), meeting any two recommendations over time (2017-2018 OR=0.97, 95% CI 0.86, 1.09; 2018-2019 OR=0.85, 95% CI 0.75, 0.97; p=0.0402) and meeting combined sleep and physical activity recommendations (2017-2018 OR=0.93, 95% CI 0.82, 1.06; 2018-2019 OR=0.82, 95% CI 0.71, 0.94; p=0.0200). Joint effects (income inequality*time) were not significant (p>0.05) for screen time or physical activity independently of sleep.
Conclusion: Adolescents attending schools in areas with greater income inequality may be at higher risk for inadequate sleep and combined short sleep and physical inactivity.
背景：关于收入不平等和青少年运动行为（身体活动、久坐行为、睡眠）的文献很少。这项研究调查了收入不平等是否与青少年长期遵守加拿大24小时运动指南（24HMG）的建议有关。方法：在大麻、肥胖、心理健康、体育活动、久坐行为和吸烟研究（2016-2017年至2018-2019年）中，来自青少年（n=9299）的纵向数据与2016年加拿大人口普查中人口普查部门（CD）水平的收入数据相关联。青少年（13-19岁）通过问卷调查报告了他们的身体活动、睡眠时间和屏幕时间。基尼系数使用2016年加拿大人口普查的税后家庭收入在CD水平上计算。采用多水平逻辑回归分析来检验收入不平等与满足若干24HMG建议之间的关系。结果：联合效应（收入不平等*时间）对于满足睡眠时间建议具有显著意义(2017-2018 OR=0.83, 95% CI 0.74, 0.92；2018-2019 or =0.77, 95% ci 0.70, 0.86；P0.05)对屏幕时间或独立于睡眠的身体活动的影响。结论：在收入差距较大的地区上学的青少年睡眠不足、睡眠不足和缺乏运动的风险更高。
