Children living in rural areas are at increased risk of overweight and obesity compared with their urban-dwelling counterparts. The purpose of this study was to provide preliminary evidence of rural children's obesogenic behaviors ( activity, sedentary behaviors, sleep, and diet) during school days, nonschool weekdays, and weekend days. A repeated measures 14-day observational study was conducted early March 2020. Children ( = 54, 92% 6-11 years old; 66% female; 98% non-Hispanic white; 22% overweight or obese) wore accelerometers on the nondominant wrist for 24 hours/day for 14 consecutive days to capture moderate-to-vigorous physical activity (MVPA), sedentary time, and sleep. Parents completed diaries to report daily activities, diet, and screen time of their child each day. Mixed effect models compared behaviors between school days, nonschool weekdays, and weekend days. Children accumulated +16 additional minutes/day of MVPA (95% confidence interval, CI: +10 to +23 minutes/day), reduced sedentary time (-68 minutes/day, 95% CI: -84 to -51 minutes/day), and reduced screen time (-99 minutes/day; 95% CI: -117 to -81 minutes/day) on school days vs. nonschool weekdays. Similar patterns were observed on school weekdays days vs. weekend days, and on nonschool days when children attended a structured program vs. days they did not attend. Minimal differences were observed in reported consumption of food groups across different days. Preliminary evidence suggests rural children display multiple unfavorable obesogenic behaviors on days when they do not attend school or other structured programs. Future interventions targeting obesogenic behaviors of rural children may want to target times when rural children are not engaged in school and "school-like" environments.
与城市居住的同龄人相比，农村地区的儿童超重和肥胖的风险增加。本研究的目的是提供农村儿童在上学日、非上学平日和周末日期间的肥胖相关行为（活动、久坐行为、睡眠和饮食）的初步证据。 2020 年 3 月初进行了一项重复测量的 14 天观察研究。儿童（ = 54 人，92%为 6-11 岁；66%为女性；98%为非西班牙裔白人；22%超重或肥胖）在非优势手腕上佩戴加速度计，每天 24 小时连续佩戴 14 天，以捕捉中等到剧烈的身体活动（MVPA）、久坐时间和睡眠。父母每天填写日记，报告孩子的日常活动、饮食和屏幕时间。混合效应模型比较了上学日、非上学平日和周末日之间的行为。与非上学平日相比，上学日儿童每天多积累 16 分钟的 MVPA（95%置信区间，CI：+10 到 +23 分钟/天），减少久坐时间（-68 分钟/天，95%CI：-84 到-51 分钟/天），减少屏幕时间（-99 分钟/天；95%CI：-117 到-81 分钟/天）。在上学日和周末日以及参加有组织活动的非上学日和不参加活动的非上学日，也观察到类似的模式。不同日子里，食物组的摄入量差异很小。 初步证据表明，农村儿童在不上学或其他有组织的活动时表现出多种不良的肥胖相关行为。未来针对农村儿童肥胖相关行为的干预措施可能需要针对农村儿童不上学和“学校式”环境的时间。
