Abstract

PURPOSE

Body mass index (BMI) and physical activity (PA) affect health-related quality of life (HRQL); however, the long-term impact of youth BMI and PA on adult HRQL is unknown. We investigated the relationship of youth BMI and PA to adult HRQL 22 years later.

METHODS

Subjects included 310 participants aged 7 to 18 in the 1981 Canada Fitness Survey, followed up in 2002-2004. The associations of youth BMI and leisure time PA to adult HRQL were examined, comparing to age- and sex-adjusted Canadian SF-36 norms.

RESULTS

Bivariate analyses revealed positive associations between youth overweight and mental aspects of adult HRQL, but little association with physical aspects. In logistic regression adjusting for adult BMI and other covariates, overweight youth were 7 times more likely than healthy weight youth to score at/above the norm on both mental health (MH) and bodily pain, and almost 18 times more likely on the mental component score (MCS). Youth BMI was also positively associated with general health (GH), social functioning, and role emotional. Removing adult BMI from the models led to attenuated associations with mental HRQL and no association with GH. Longitudinal BMI status change was explored, and findings supported the main regression results. Youth PA was not associated with adult HRQL.

CONCLUSIONS

Youth overweight conveyed a long-term positive impact on several aspects of adult HRQL, and this impact may be both direct and indirect through BMI change and the effect on adult BMI. Youth PA had no long-term impact on adult HRQL.

摘要

目的

体重指数(BMI)和身体活动(PA)会影响健康相关生活质量(HRQL);然而,青少年 BMI 和 PA 对成人 HRQL 的长期影响尚不清楚。我们调查了青少年 BMI 和 PA 与 22 年后成人 HRQL 的关系。

方法

本研究的对象是参加 1981 年加拿大健身调查的 310 名 7 至 18 岁的参与者,随后在 2002-2004 年进行了随访。通过与年龄和性别调整后的加拿大 SF-36 标准进行比较,检验了青少年 BMI 和休闲时间 PA 与成人 HRQL 的相关性。

结果

双变量分析显示,青少年超重与成人 HRQL 的心理方面呈正相关,但与身体方面相关性较小。在调整成人 BMI 和其他协变量的逻辑回归中,超重青少年在心理健康(MH)和身体疼痛两个方面达到/超过标准的可能性是健康体重青少年的 7 倍,在心理成分得分(MCS)上的可能性几乎是 18 倍。青少年 BMI 也与一般健康(GH)、社会功能和角色情绪呈正相关。从模型中去除成人 BMI 后,与心理健康的相关性减弱,与 GH 没有关联。还探讨了青少年 BMI 纵向变化情况,结果支持了主要回归结果。青少年 PA 与成人 HRQL 无关。

结论

青少年超重对成人 HRQL 的多个方面产生了长期的积极影响,这种影响可能是直接的,也可能是通过 BMI 变化和对成人 BMI 的影响间接产生的。青少年 PA 对成人 HRQL 没有长期影响。
