Psychometric Properties of a Parental Questionnaire for Assessing Correlates of Toddlers’ Physical Activity and Sedentary Behavior

This study examined the psychometric properties of a questionnaire developed with the guidance of the socialization model of child behaviour to understand modifiable correlates of toddlers’ physical activity and sedentary behaviour. Findings are based on 118 parents (33.7 ± 4.9 years; 86% female) of toddlers (19.3 ± 2.7 months; 48% female) from Edmonton, Canada in The Parents’ Role in Establishing healthy Physical activity and Sedentary behaviour habits study (PREPS). The PREPS questionnaire encompassed 21 variables across the constructs of the socialization model of child behaviour. Of the nine variables assessed for internal consistency reliability, eight had good (α ≥ 0.70) reliability. Of the 15 continuous variables assessed for 1-week test–retest reliability, 10 had moderate (intra-class correlation = 0.50–0.74) and 5 had good (intra-class correlation ≥ 0.75) reliability. Of the six categorical variables assessed for 1-week test–retest reliability, two had fair (К = 0.21–0.40), one had moderate (К = 0.41–0.60), one had substantial (К = 0.61–0.80), and two had almost perfect (К = 0.81–1.00) reliability. Of the 12 sedentary behaviour variables assessed for convergent validity, 7 were significantly correlated with children’s screen time, of which three were small (r ≤ 0.29), two were medium (r = 0.30–0.49), and two were large (r ≥ 0.50) effect sizes.

短期封闭式综合干预对肥胖男少年体成分、瘦素及睾酮的影响

目的:探寻短期(15天)封闭综合干预对肥胖男少年体成分、瘦素及性激素的影响,为防治少年肥胖,改善性发育不良提供科学的实验依据.方法:10名体脂含量正常男少年为对照组,10名肥胖男少年为实验组(给予短期综合干预),干预前测定对照组与实验组相关指标进行组间比较,干预后测定实验组相关指标进行组内比较.结果:干预前实验组体成分、血糖、胰岛素、瘦素均显著高于对照组(P＜0.01;P＜0.01;P＜0.01;P＜0.05),睾酮显著低于对照组(P＜0.05);干预后实验组体重、体脂含量、体脂率、瘦体重、血糖、胰岛素、瘦素、睾酮均显著下降(P＜0.01;P＜0.01;P＜0.01;P＜0.01;P＜0.01、P＜0.01、P＜0.01、P＜0.05);胰岛素与体重、体脂含量、体脂率、瘦体重呈正相关(P＜0.05;P ＜0.01;P＜0.01;P＜0.05),瘦素与体脂含量、体脂率、胰岛素呈正相关(P＜0.05;P＜0.01;P＜0.05).结论:短期(15天)的综合干预能有效地减少肥胖男少年的体脂含量,改善胰岛素抵抗和瘦素抵抗,但对改善肥胖男少年性发育不良暂时无明显影响,长期的影响还有待进一步的研究.
