Studies suggest an association between weight change and subsequent poor physical health functioning, whereas the association with mental health functioning is inconsistent. We aimed to examine whether obesity and change of body mass index among normal weight, overweight and obese women and men associate with changes in physical and mental health functioning.
The Helsinki Health Study cohort includes Finnish municipal employees aged 40 to 60 in 2000-02 (phase 1, response rate 67%). Phase 2 mail survey (response rate 82%) took place in 2007 and phase 3 in 2012 (response rate 76%). This study included 5668 participants (82% women). Seven weight change categories were formed based on body mass index (BMI) (phase 1) and weight change (BMI change ≥5%) (phase 1-2). The Short Form 36 Health Survey (SF-36) measured physical and mental health functioning. The change in health functioning (phase 1-3) score was examined with repeated measures analyses. Covariates were age, sociodemographic factors, health behaviours, and somatic ill-health.
Weight gain was common among women (34%) and men (25%). Weight-gaining normal weight (-1.3 points), overweight (-1.3 points) and obese (-3.6 points) women showed a greater decline in physical component summary scores than weight-maintaining normal weight women. Among weight-maintainers, only obese (-1.8 points) women showed a greater decline than weight-maintaining normal weight women. The associations were similar, but statistically non-significant for obese men. No statistically significant differences in the change in mental health functioning occurred.
Preventing weight gain likely helps maintaining good physical health functioning and work ability.
研究表明体重变化与随后较差的身体健康功能之间存在关联，而与心理健康功能的关联则不一致。我们旨在研究正常体重、超重和肥胖的女性及男性中肥胖及体重指数变化是否与身心健康功能的变化相关。
赫尔辛基健康研究队列包括2000 - 2002年年龄在40至60岁的芬兰市政雇员（第一阶段，应答率67%）。2007年进行了第二阶段邮寄调查（应答率82%），2012年进行了第三阶段调查（应答率76%）。本研究纳入了5668名参与者（82%为女性）。根据体重指数（BMI）（第一阶段）和体重变化（BMI变化≥5%）（第一阶段至第二阶段）形成了七个体重变化类别。采用简短健康调查问卷（SF - 36）测量身心健康功能。通过重复测量分析检验健康功能（第一阶段至第三阶段）得分的变化。协变量包括年龄、社会人口学因素、健康行为和躯体健康不佳情况。
女性（34%）和男性（25%）中体重增加很常见。体重增加的正常体重女性（-1.3分）、超重女性（-1.3分）和肥胖女性（-3.6分）的身体成分汇总得分下降幅度大于体重保持不变的正常体重女性。在体重保持者中，只有肥胖女性（-1.8分）的得分下降幅度大于体重保持不变的正常体重女性。肥胖男性的关联情况相似，但无统计学意义。心理健康功能变化方面未出现统计学显著差异。
预防体重增加可能有助于维持良好的身体健康功能和工作能力。
