To examine the effects of the National Aeronautics and Space Administration Mission-X: Train Like an Astronaut program (MX) on children's health-related knowledge and behaviors of a sample of US participants.
A nonexperimental pilot intervention study in 5 cities with a pre-post comparison of children's health-related knowledge and behaviors in the United States in 2014 and 2015.
Children (n = 409) with a mean age (standard deviation) of 10.1 (1.7) years.
Children answered pre- and postintervention questionnaires. We measured the differences in children's health knowledge on nutrition and physical fitness and behaviors on diet and physical activity as scores.
A 6-week web- and school-based intervention for a healthier lifestyle by introducing physical fitness and science activities based on actual astronaut training under a teacher's supervision.
Nonparametric analysis and logistic regression models.
Participants significantly improved both of their health behaviors on physical activity ( P < .001) and diet ( P = .06) and their health knowledge regarding nutrition ( P < .001) and physical fitness ( P < .001) after the intervention. The improvement in children's behaviors ( P < .001), knowledge ( P < .001), and the total score ( P < .001) after intervention did not significantly vary by sex or age, after adjusting for year of participation and state of residency.
The MX seems effective in improving health behaviors and health knowledge of participating children, which may serve as a model for sustainable global child health promotion program. Further research is needed to test its long-term effects on child health.
研究美国国家航空航天局“像宇航员一样训练”任务X计划（MX）对美国部分参与者的儿童健康相关知识及行为的影响。
一项非实验性试点干预研究，在5个城市开展，对2014年和2015年美国儿童的健康相关知识及行为进行前后对比。
409名儿童，平均年龄（标准差）为10.1（1.7）岁。
儿童在干预前后回答问卷。我们将儿童在营养和身体健康方面的健康知识差异以及饮食和身体活动方面的行为差异作为得分进行测量。
在教师监督下，通过引入基于实际宇航员训练的体育活动和科学活动，开展为期6周的网络和学校干预，以促进更健康的生活方式。
非参数分析和逻辑回归模型。
干预后，参与者在身体活动（P <.001）和饮食（P =.06）方面的健康行为以及在营养（P <.001）和身体健康（P <.001）方面的健康知识均有显著改善。在调整参与年份和居住州后，干预后儿童行为（P <.001）、知识（P <.001）和总分（P <.001）的改善在性别或年龄上没有显著差异。
MX计划似乎在改善参与儿童的健康行为和健康知识方面有效，这可能为全球可持续儿童健康促进计划提供一个模式。需要进一步研究来测试其对儿童健康的长期影响。
