概括
在幼儿中,加速度计的佩戴时间和活动日志的完成是具有挑战性的. 婚姻支持可能会改善对体力活动研究协议的遵守,尽管数据质量仍然令人担忧.
科学领域:
- 儿科体育活动测量测量
- 在研究合规性方面的行为科学.
背景情况:
- 使用加速度计来准确测量幼儿的体力活动,由于不遵守佩戴时间和活动日志指令而受到阻碍.
- 了解影响合规性的因素对于提高研究结果的有效性至关重要.
研究的目的:
- 调查穿戴时间和活动日志完成与幼儿人口,社会经济和育儿风格变量之间的关系.
- 为了确定幼儿的静坐时间是否根据活动日志完成而不同.
主要方法:
- 从一项涉及父母和幼儿 (12-35个月) 的随机对照试验中获得的基线数据的二次分析.
- 幼儿戴着ActiGraph wGT3x加速度计,家长填写活动日志.
- 有效日需要至少600分钟的佩戴时间;分析包括ANOVA和千平方测试.
主要成果:
- 50个家庭参与了调查,56%的家庭提交了有效的加速度计数据和活动日志.
- 关系中的参与者更有可能完成活动日志 (P < .05).
- 在没有完成活动日志的和没有完成活动日志的婴儿之间,没有发现婴儿静坐时间的显著差异.
结论:
- 遵守磨损时间和完成活动日志的情况各不相同,返回的活动日志质量差影响了数据有效性.
