背景：在加拿大，31.5%的儿童超重或肥胖，使他们面临慢性合并症和过早死亡的风险增加。身体活动、健康饮食和屏幕时间是儿童超重和肥胖的重要行为决定因素，而家庭环境，特别是父母的支持行为会对儿童超重和肥胖产生影响。然而，目前对哪些类型的支持行为对健康儿童行为产生最大的积极影响的了解有限。本研究旨在确定不同类型的父母支持行为对预测儿童在日常体育活动、日常水果和蔬菜消费以及娱乐屏幕时间方面满足既定指导方针的可能性的相对贡献。方法：采用计算机辅助电话访谈法，随机抽取安大略省至少有一名18岁以下儿童的父母或监护人（n = 3,206）进行数据收集。建立了三个多变量逻辑回归模型来预测父母是否报告他们的孩子符合指南。自变量包括父母和子女的年龄和性别、父母支持行为的多项指标以及社会人口特征。父母的支持行为被分类为基于适应框架的动机性、工具性、规范性和条件性。结果：控制模型中的所有其他因素，发现几种父母支持行为是儿童满足既定健康指南的重要预测因素。例如，有条件的支持行为，包括带孩子去他们可以活动的地方（OR: 2.06; 95% CI: 1.32-3.21），以及与家人一起吃饭时远离电视（95% CI: 1.15-2.41），分别是儿童达到身体活动和水果和蔬菜指南的显著积极预测因素。结论：旨在改善特定父母支持行为的健康促进工作可能是减轻儿童超重负担的有效杠杆。因此，在预防和减少儿童超重和肥胖的任何综合办法中，都应充分考虑到支持行为的影响。
Background: In Canada, 31.5 % of children are overweight or obese, putting them at an increased risk of chronic comorbidities and premature mortality. Physical activity, healthy eating, and screen time are important behavioural determinants of childhood overweight and obesity that are influenced by the family environment, and particularly parents' support behaviours. However, there is currently a limited understanding of which types of these support behaviours have the greatest positive impact on healthy child behaviours. This study aims to determine the relative contribution of different types of parental support behaviours for predicting the likelihood that children meet established guidelines for daily physical activity, daily fruit and vegetable consumption, and recreational screen time.Methods: A Computer Assisted Telephone Interview survey was used to collect data from a random sample of parents or guardians with at least one child under the age of 18 in Ontario (n = 3,206). Three multivariable logistic regression models were built to predict whether or not parents reported their child was meeting guidelines. Independent variables included parent and child age and gender, multiple indicators of parental support behaviours, and socio-demographic characteristics. Parental support behaviours were categorized post-hoc as motivational, instrumental, regulatory, and conditional based on an adapted framework.Results: Controlling for all other factors in the model, several parental support behaviours were found to be significant predictors of children meeting established health guidelines. For example, conditional support behaviours including taking the child to places where they can be active (OR: 2.06; 95 % CI: 1.32-3.21), and eating meals as a family away from the TV (95 % CI: 1.15-2.41) were significant positive predictors of children meeting physical activity and fruit and vegetable guidelines, respectively.Conclusions: Health promotion efforts aimed at improving particular parent support behaviours could be effective levers for mitigating the burden of excess body weight in childhood. As such, the influence of support behaviours should be fully considered in any comprehensive approach to prevention and reduction of childhood overweight and obesity.
