To identify the most relevant determinants involved in Physical Activity (PA) changes in the EVIDENT 3 study population, measured by the International PA Questionnaire (IPAQ) and the Actigraph GT3X accelerometer.
Exploratory study. Data used were collected from EVIDENT 3 study ( = 650). Items to measure psychological determinants were chosen from the baseline questionnaires. PA minutes/week were assessed by an accelerometer and IPAQ. The sample was analyzed by the control group (CG), the intervention group (IG) and Body Mass Index, using Confidence Interval-Based Estimation of Relevance (CIBER) analyses.
486 participants, (IG: = 251, CG: = 235) were included. IG shows a positive association between PA assessed by accelerometer and self-efficacy. In IG, the overweight sample shows a positive association between PA assessed by accelerometer and motivation and self-efficacy. PA assessed by accelerometer obtained a higher explained variance ( ) in IG, both people with overweight (.10 - .55) and obesity (.03 - .19). In CG, IPAQ reached better results in people with overweight (.12 - .49).
Motivation and self-efficacy showed as relevant in increasing PA minutes/week, but only in the people with overweight in IG. There might be other factors not analyzed that could improve the low R obtained.
为了确定EVIDENT 3研究人群中与身体活动(PA)变化最相关的决定因素,采用国际身体活动问卷(IPAQ)和Actigraph GT3X加速度计进行测量。
探索性研究。使用的数据来自EVIDENT 3研究(n = 650)。测量心理决定因素的项目从基线问卷中选取。每周的PA分钟数通过加速度计和IPAQ进行评估。使用基于置信区间的相关性估计(CIBER)分析,对对照组(CG)、干预组(IG)和体重指数的样本进行分析。
纳入了486名参与者(IG:n = 251,CG:n = 235)。IG显示,通过加速度计评估的PA与自我效能之间存在正相关。在IG中,超重样本显示,通过加速度计评估的PA与动机和自我效能之间存在正相关。在IG中,无论是超重人群(0.10 - 0.55)还是肥胖人群(0.03 - 0.19),通过加速度计评估的PA获得了更高的解释方差( )。在CG中,IPAQ在超重人群中取得了更好的结果(0.12 - 0.49)。
动机和自我效能在增加每周PA分钟数方面显示出相关性,但仅在IG中的超重人群中如此。可能存在其他未分析的因素可以改善所获得的低R值。
