背景:为了评估COVID-19大流行后的第一个完整学年中早餐和用水量的变化是否因性别/性别而异,种族/民族,加拿大青少年的社会经济地位。
方法:在COVID-19发病前(2019年10月至2020年3月)和发病后(2020年11月至2021年6月)收集的前瞻性年度调查数据,肥胖,心理健康,身体活动,酒精,吸烟,和久坐行为(COMPASS)研究。样本由8,128名学生组成;来自41所加拿大中学的便利样本的平均(SD)年龄=14.2(1.3)年。在这两个时间点,自我报告的早餐和水消耗被分为每天或不每天。基于人口统计因素,使用具有学校聚类的多变量logistic广义估计方程来估计COVID-19后日常消费的维持/采用差异,同时控制COVID-19之前的行为。
结果:报告了具有95%置信区间的调整比值比(AOR)。女性(AOR=0.71[0.63,0.79])和社会经济地位较低的个人(最低:最高=0.41[0.16,1.00])在2020-2021学年中,与男性和社会经济地位较高的同龄人相比,维持/采用每日早餐消费的可能性较小。与所有其他种族/民族身份相比,黑人识别个体不太可能维持/采用每周每天的普通水消耗(AOR=0.33[0.15,0.75],p<0.001)。未检测到显著的交互效应。
结论:结果支持这样的假设,即不同人口群体的营养行为变化并不相同。女性,较低的社会经济地位,黑人青少年的健康营养行为下降幅度更大。为提高对每日早餐和水消耗的依从性而采取的公共卫生干预措施应针对这些人群。
背景:不是试验。
BACKGROUND: To assess whether changes in breakfast and water consumption during the first full school year after the emergence of the COVID-19 pandemic varied based on sex/gender, race/ethnicity, and socioeconomic status among Canadian adolescents.
METHODS: Prospective annual survey data collected pre- (October 2019-March 2020) and post-COVID-19 onset (November 2020-June 2021) the Cannabis, Obesity, Mental health, Physical activity, Alcohol, Smoking, and Sedentary behaviour (COMPASS) study. The sample consisted of 8,128 students; mean (SD) age = 14.2 (1.3) years from a convenience sample of 41 Canadian secondary schools. At both timepoints self-reported breakfast and water consumption were dichotomized as daily or not. Multivariable logistic generalized estimating equations with school clustering were used to estimate differences in maintenance/adoption of daily consumption post-COVID-19 based on demographic factors, while controlling for pre-COVID-19 behaviour.
RESULTS: Adjusted odds ratios (AOR) with 95% confidence intervals are reported. Females (AOR = 0.71 [0.63, 0.79]) and lower socioeconomic status individuals (AORLowest:Highest=0.41 [0.16, 1.00]) were less likely to maintain/adopt daily breakfast consumption than male and higher socioeconomic status peers in the 2020-2021 school year. Black identifying individuals were less likely than all other racial/ethnic identities to maintain/adopt plain water consumption every day of the week (AOR = 0.33 [0.15, 0.75], p < 0.001). No significant interaction effects were detected.
CONCLUSIONS: Results support the hypothesis that changes in nutritional behaviours were not equal across demographic groups. Female, lower socioeconomic status, and Black adolescents reported greater declines in healthy nutritional behaviours. Public health interventions to improve adherence to daily breakfast and water consumption should target these segments of the population.
BACKGROUND: Not a trial.
