The aim of this study is to investigate associations of screen-time and physical activity (PA) with self-efficacy for PA, intrinsic motivation to PA and health-related quality of life (HRQoL) in Colombian schoolchildren from socioeconomically disadvantaged neighborhoods, and to compare these variables among children with normal-weight (NW), overweight (OW) and obesity (OB).
In 678 schoolchildren (age 10-14 years) screen-time (TV, video games, computer) and number of days being physically active ≥ 60 minutes were self-reported. Multi-item scales were used to assess self-efficacy to PA and intrinsic motivation to PA. The KIDSCREEN-27 was used to assess HRQoL.
Screen-time was associated with HRQoL in the school/learning environment dimension. Number of days being physically active was associated with self-efficacy for PA, intrinsic motivation for PA and with HRQoL concerning physical well-being, autonomy/parent relation and social support/peers. Group differences were found for days being physically active (OW = 2.8 and OB = 2.7 vs. NW = 3.3) but not for screen-time (NW = 5.0, OW = 4.7 and OB = 5.7 hrs·d-1). OW and OB scored lower on intrinsic motivation to PA than NW (OW = 19.2 and OB = 17.9 versus NW = 20.1). All 3 groups differed in physical well-being scores (NW = 50.3, OW = 48.1, OB = 40.6, P < .001).
Schoolchildren with overweight and obesity from socioeconomically disadvantaged neighborhoods need additional motivational support to perform health-enhancing PA to experience higher physical well-being.
本研究旨在调查来自社会经济条件不利社区的哥伦比亚学童的屏幕时间和身体活动(PA)与PA自我效能感、PA内在动机以及健康相关生活质量(HRQoL)之间的关联,并比较正常体重(NW)、超重(OW)和肥胖(OB)儿童之间的这些变量。
678名10 - 14岁学童自行报告屏幕时间(电视、电子游戏、电脑)以及每周进行≥60分钟身体活动的天数。使用多项目量表评估PA自我效能感和PA内在动机。采用儿童生活质量量表27项版(KIDSCREEN - 27)评估HRQoL。
在学校/学习环境维度中,屏幕时间与HRQoL相关。每周进行身体活动的天数与PA自我效能感、PA内在动机以及身体健康、自主/亲子关系和社会支持/同伴方面的HRQoL相关。在每周进行身体活动的天数上发现了组间差异(OW = 2.8天,OB = 2.7天,而NW = 3.3天),但在屏幕时间上未发现差异(NW = 5.0小时·天 - 1,OW = 4.7小时·天 - 1,OB = 5.7小时·天 - 1)。OW和OB在PA内在动机方面的得分低于NW(OW = 19.2分,OB = 17.9分,而NW = 20.1分)。所有三组在身体健康得分上存在差异(NW = 50.3分,OW = 48.1分,OB = 40.6分,P <.001)。
来自社会经济条件不利社区的超重和肥胖学童需要额外的动机支持来进行促进健康的PA,以体验更高的身体健康水平。
