There are disproportionately higher rates of overweight and obesity in poor rural communities but studies exploring children's health-related behaviors that may assist in designing effective interventions are limited. We examined the association between overweight and obesity prevalence of 401 ethnically/racially diverse, rural school-aged children and healthy-lifestyle behaviors: improving diet quality, obtaining adequate sleep, limiting screen-time viewing, and consulting a physician about a child's weight.
A cross-sectional analysis was conducted on a sample of school-aged children (6-11 years) in rural regions of California, Kentucky, Mississippi, and South Carolina participating in CHANGE (Creating Healthy, Active, and Nurturing Growing-up Environments) Program, created by Save the Children, an independent organization that works with communities to improve overall child health, with the objective to reduce unhealthy weight gain in these school-aged children (grades 1-6) in rural America. After measuring children's height and weight, we17 assessed overweight and obesity (BMI ≥ 85th percentile) associations with these behaviors: improving diet quality18 (≥ 2 servings of fruits and vegetables/day), reducing whole milk, sweetened beverage consumption/day; obtaining19 adequate night-time sleep on weekdays (≥ 10 hours/night); limiting screen-time (i.e., television, video, computer,20 videogame) viewing on weekdays (≤ 2 hours/day); and consulting a physician about weight. Analyses were adjusted 21 for state of residence, children's race/ethnicity, gender, age, and government assistance.
Overweight or obesity prevalence was 37 percent in Mississippi and nearly 60 percent in Kentucky. Adjusting for covariates, obese children were twice as likely to eat ≥ 2 servings of vegetables per day (OR=2.0,95% CI 1.1-3.4), less likely to consume whole milk (OR=0.4,95% CI 0.2-0.70), Their parents are more likely to be told by their doctor that their child was obese (OR=108.0,95% CI 21.9-541.6), and less likely to report talking to their child about fruits and vegetables a lot/sometimes vs. not very much/never (OR=0.4, 95%CI 0.2-0.98) compared to the parents of healthy-weight children.
Rural children are not meeting recommendations to improve diet, reduce screen time and obtain adequate sleep. Although we expected obese children to be more likely to engage in unhealthy behaviors, we found the opposite to be true. It is possible that these groups of respondent parents were highly aware of their weight status and have been advised to change their children's health behaviors. Perhaps given the opportunity to participate in an intervention study in combination with a physician recommendation could have resulted in actual behavior change.
贫困农村社区的超重和肥胖率过高,但探索可能有助于设计有效干预措施的儿童健康相关行为的研究有限。我们研究了 401 名具有不同种族/族裔背景的农村学龄儿童超重和肥胖的患病率与健康生活方式行为之间的关系:改善饮食质量、获得充足的睡眠、限制屏幕时间观看以及咨询医生有关孩子的体重。
对加利福尼亚州、肯塔基州、密西西比州和南卡罗来纳州农村地区参加由拯救儿童组织(一个与社区合作以改善整体儿童健康的独立组织)创建的 CHANGE(创建健康、积极和培养成长环境)计划的学龄儿童(6-11 岁)进行横断面分析,旨在减少美国农村地区这些学龄儿童(1-6 年级)的不健康体重增加。在测量儿童的身高和体重后,我们评估了超重和肥胖(BMI≥85 百分位)与以下行为的关联:改善饮食质量(每天≥2 份水果和蔬菜)、减少全脂牛奶、含糖饮料的摄入量/天;在工作日获得足够的夜间睡眠时间(每晚≥10 小时);在工作日限制屏幕时间(即电视、视频、计算机、视频游戏)观看时间(每天≤2 小时);并就体重咨询医生。分析调整了居住州、儿童种族/族裔、性别、年龄和政府援助等因素。
密西西比州的超重或肥胖患病率为 37%,肯塔基州则接近 60%。在调整了协变量后,肥胖儿童每天吃≥2 份蔬菜的可能性是两倍(OR=2.0,95%CI 1.1-3.4),不太可能饮用全脂牛奶(OR=0.4,95%CI 0.2-0.70)。他们的父母更有可能被告知医生他们的孩子肥胖(OR=108.0,95%CI 21.9-541.6),并且与健康体重儿童的父母相比,他们更有可能报告与孩子谈论水果和蔬菜的次数较多/有时,而不是不太多/从不(OR=0.4,95%CI 0.2-0.98)。
农村儿童不符合改善饮食、减少屏幕时间和获得充足睡眠的建议。尽管我们预计肥胖儿童更有可能参与不健康的行为,但事实恰恰相反。这些组别的受调查父母可能非常了解自己的体重状况,并被告知要改变孩子的健康行为。也许,如果有机会参加干预研究并结合医生的建议,可能会导致实际行为的改变。
