Little information is available on the use of text messages through mobile phones to address overweight/obesity in children. This study aims to evaluate the impact of a text message-based intervention for weight control and health-promoting lifestyle behaviors of overweight/obese children.
This quasi-experimental study was conducted among overweight/obese school students. Data on sociodemographic, dietary intake, sleep, sedentary behavior, physical activity (PA), and anthropometry were collected before and after the intervention. Weight and height were examined according to the standard protocols. The intervention was consisted of tailored messages for weight control and healthy lifestyle, including diet, PA, sedentary behavior, and sleep. Child attitude and his practice were asked before and after the intervention. The paired -test was performed to compare means of continuous variables before and after the intervention for normal distribution data. The Wilcoxon test was also used for nonnormal data.
A total of 71 boy students were included in the study (62% obese). The mean age was 10.07 years. The means of attitude score for PA, nutrition, and sleep after intervention were greater than before it, but it was significant only for PA. The mean of nighttime sleep duration of students after the intervention was significantly less. Furthermore, unhealthy score decreases after the intervention.
Three-month lifestyle intervention as text messages had positive effects on the nutritional intake of obese children and their attitudes toward PA, but no effect on child body mass index.
关于通过手机短信解决儿童超重/肥胖问题的信息较少。本研究旨在评估基于短信的干预措施对超重/肥胖儿童体重控制和促进健康生活方式行为的影响。
本准实验研究在超重/肥胖的在校学生中进行。在干预前后收集社会人口统计学、饮食摄入、睡眠、久坐行为、身体活动（PA）和人体测量学数据。根据标准方案检查体重和身高。干预措施包括针对体重控制和健康生活方式的定制信息，包括饮食、PA、久坐行为和睡眠。在干预前后询问儿童的态度和行为。对正态分布数据，采用配对t检验比较干预前后连续变量的均值。对非正态数据也使用Wilcoxon检验。
共有71名男学生纳入研究（62%为肥胖）。平均年龄为10.07岁。干预后PA、营养和睡眠的态度得分均值高于干预前，但仅PA得分有显著差异。干预后学生夜间睡眠时间均值显著减少。此外，干预后不健康得分降低。
为期三个月的短信生活方式干预对肥胖儿童的营养摄入及其对PA的态度有积极影响，但对儿童体重指数没有影响。
