摘要:
了解采用结合移动健康技术辅助饮食及身体活动的综合干预对学校儿童人群进行干预的效果,为有效开展儿童超重肥胖干预提供依据.方法 选取北京市城区和郊区各1 所学校共58 名四年级学生进行3 个月的综合性肥胖干预,干预期间采用微信服务号的形式加强家长互动.在干预前后分别进行身高、体重、腰围、臀围、血压及体成分等身体测量,并调查肥胖相关的饮食及身体活动行为的达标情况.结果 干预前后儿童的体质量指数Z 评分、腰臀比及舒张压差值分别为-0.13,-0.02 和-2.47 mmHg,均有统计学意义(t 值分别为-4.24,-2.07,2.15,P 值均<0.05).超重肥胖率和中心肥胖率均下降(39.60%和34.48%, 36.21%和32.76%),但差异均无统计学意义(P 值均>0.05).干预前后肥胖相关的行为达标率除过量饮食外均得到提高,且差异均有统计学意义(χ2 值分别为3.85,4.00,8.26,7.54,9.85,P 值均<0.05).结论 采取移动健康技术辅助的饮食和身体活动的综合性干预措施对儿童肥胖相关指标的改善有较好效果.

Abstract:
Objective To assess the effectiveness of a comprehensive school-based intervention combining diet and physical activity components with a mobile health technology on childhood obesity. Methods Fifty-eight four-grade students were recruited from an urban and a rural school in Beijing and participated in the 3-months comprehensive intervention. WeChat platform was used to promote communication with students' parents during the intervention period. All students underwent measurements of height, weight, waist circumference, hip circumference, blood pressure, body fat percentage, and obesity-related diet and physical activity behaviors at baseline and three months after the intervention. Results After the intervention, the body mass index Z-score, waist-to-hip ratio and diastolic pressure declined by 0.13 kg /m2, 0.02 and 2.47 mmHg statistically(P<0.05). Healthy eating and physical activity behaviors improved significantly(P<0.05) except for overeating. Conclusion A comprehensive school-based intervention combining diet and physical activity components with a mobile health technology showed moderate effect on improving obesity-related outcomes in children.
