摘要:
目的 研究儿童饮食运动行为干预中手机应用程序(APP)使用的依从性及其影响因素,为未来提高干预依从性提供科学依据。 方法 基于在北京、山西长治和新疆乌鲁木齐3座城市开展的一项儿童饮食运动行为干预项目,通过整群随机对照试验,调查干预组694名儿童和家长在干预过程中手机APP使用情况,通过APP点击次数评估APP使用依从性,通过Logistic回归模型分析可能影响APP使用依从性的因素。 结果 手机APP在知识传播、行为监测、家庭作业上传和评估反馈4个部分使用次数M(P25, P75)分别为10(5, 21)、20(14, 26)、7(4, 10)、26(15, 53)次。多因素Logistic回归分析发现,长治地区(OR=1.67,95%CI=1.12~2.48)和主要照顾者为母亲(OR=1.55,95%CI=1.09~2.22)的研究对象对APP使用的依从性较好,而母亲有工作者(OR=0.47,95%CI=0.31~0.74)对APP使用的依从性较差(P值均 < 0.05)。 结论 儿童饮食运动行为干预中手机APP使用依从性较好,地区、主要照顾者是否为母亲、母亲是否工作可能影响依从性的因素。 Abstract:Objective To study the compliance and associated factors of smartphone application (APP) usage in childhood dietary and exercise intervention. Methods Based on one childhood intervention of diet and exercise in Beijing, Changzhi of Shanxi Province and Urumqi of Xinjiang Province, 694 children (and their primary caregivers) in the intervention group were investigated regarding usage of APP during the intervention. Compliance of APP usage was evaluated by the click times of APP, and Logistic regression models were used to analyze influencing factors of the compliance. Results The median (inter-quartile range) click times of APP in the four modules (information dissemination, behavior monitoring, homework uploading and feedback) were 10 (5, 21), 20 (14, 26), 7(4, 10), 26 (15, 53), respectively. Multivariable logistic regression analysis found that compliance of APP usage was higher among subjects in Changzhi region (OR=1.67, 95%CI=1.12-2.48), whose primary caregiver was mother (OR=1.55, 95%CI=1.09-2.22), or whose mother did not work (OR=0.47, 95%CI=0.31-0.74). Conclusion Compliance of APP usage was generally high in the childhood intervention of diet and exercise. Some factors are associated with compliance of APP usage. Findings of the study provide a scientific basis for better implementation of APP-based childhood interventions of diet and exercise in the future. -
