Fundamental movement skills are a correlate of physical activity and weight status. Children who participated in a preschool intervention had greater movement skill proficiency and improved anthropometric measures (waist circumference and BMI z scores) post intervention. Three years later, intervention girls had retained their object control skill advantage. The study purpose was to assess whether at 3-year follow up a) intervention children were more physically active than controls and b) the intervention effect on anthropometrics was still present.
Children were assessed at ages 4, 5, and 8 years for anthropometric measures and locomotor and object control proficiency (Test of Gross Motor Development-2). At age 8, children were also assessed for moderate to vigorous physical activity (MVPA) (using accelerometry). Several general linear models were run, the first with MVPA as the outcome, intervention/control, anthropometrics, object control and locomotor scores as predictors, and age and sex as covariates. The second and third models were similar, except baseline to follow-up anthropometric differences were the outcome.
Overall follow-up rate was 29% (163/560), with 111 children having complete data. There were no intervention control differences in either MVPA or anthropometrics.
Increased skill competence did not translate to increased physical activity.
基本运动技能与身体活动及体重状况相关。参与学前干预的儿童在干预后运动技能熟练度更高，人体测量指标（腰围和BMI z评分）也有所改善。三年后，干预组女孩仍保持其物体控制技能优势。本研究的目的是评估在3年随访时：a）干预组儿童是否比对照组儿童身体活动更多；b）干预对人体测量指标的影响是否仍然存在。
在儿童4岁、5岁和8岁时评估其人体测量指标以及运动和物体控制熟练度（粗大运动发育测试-2）。在8岁时，还使用加速度计评估儿童的中度至剧烈身体活动（MVPA）。运行了几个一般线性模型，第一个模型以MVPA为结果变量，干预/对照、人体测量指标、物体控制和运动得分作为预测变量，年龄和性别作为协变量。第二个和第三个模型类似，只是结果变量是基线到随访期间人体测量指标的差异。
总体随访率为29%（163/560），111名儿童有完整数据。在MVPA或人体测量指标方面，干预组与对照组没有差异。
技能能力的提高并未转化为身体活动的增加。
