夫妻同时改正坏习惯有助双方获得健康习惯

  近日，一篇刊登在国际杂志JAMA Internal Medicine上的研究报告指出，如果夫妻中的一方经常做出一些积极的改变，那么另外一方也将会成功收获健康的生活习惯，相关研究由英国癌症研究所的研究人员开展。

  比如在吸烟的女性人群中，如果其伴侣戒烟的话，50%的个体也会同时尽力去戒烟；而如果伴侣并不吸烟的话，那么仅有17%的女性个体会戒烟。研究结果表明，男性受其伴侣的影响是平等的，但如果其伴侣做出一些相同的行为改变，那么这些男性个体更有可能戒烟、变得自信同时也会尽力去减肥。

  文章中，研究者对已婚或生活在一起的50岁以上的3772对夫妻进行观察研究，研究者Jane Wardle表示，不健康的生活方式是全球范围内慢性疾病死亡的主要风险因子，其中一些关键的生活方式风险因子包括：吸烟、过重、缺乏体能锻炼、不良饮食及酗酒等。因此改变不良习惯或可减少诸如癌症等疾病所引发的的死亡风险。

  研究者表示，如今在生活方式上做出改变对于改善健康和癌症风险的意义重大，而本研究就表明当夫妻间共同做出一些习惯改变时往往更容易取得成功；当然得到一定的支持也可以帮助人们拥有更多健康的习惯，比如如果你想减肥的话，可以让你的伴侣或者好朋友跟你一起进行减肥，这样或许可以更加有效地促进减肥。

  保持健康的生活习惯、维持健康的体重并且保持自信对于降低癌症的风险非常重要，因此生活中夫妻家人间要互相帮助和鼓励帮助彼此更好地去除不良习惯，保持机体的健康。（转化医学网360zhyx.com）

The Influence of Partner’s Behavior on Health Behavior Change The English Longitudinal Study of Ageing

Importance Couples are highly concordant for unhealthy behaviors, and a change in one partner’s health behavior is often associated with a change in the other partner’s behavior. However, no studies have explicitly compared the influence of having a partner who takes up healthy behavior (eg, quits smoking) with one whose behavior is consistently healthy (eg, never smokes).
Objective To examine the influence of partner’s behavior on making positive health behavior changes.
Design, Setting, and Participants We used prospective data from married and cohabiting couples (n, 3722) participating in the English Longitudinal Study of Ageing, a large population-based cohort of older adults (≥50 years). Studying men and women who had unhealthy behaviors in 3 domains at baseline (ie, smoking, physically inactive, or overweight/obese), we used logistic regression analysis to examine the influence of the partner’s behavior in the same domain on the odds of positive health behavior change over time.
Main Outcomes and Measures Smoking cessation, increased physical activity, and 5% weight loss or greater.
Results Across all domains, we found that when one partner changed to a healthier behavior (newly healthy), the other partner was more likely to make a positive health behavior change than if their partner remained unhealthy (smoking: men 48% vs 8%, adjusted odds ratio [OR], 11.82 [95% CI, 4.84-28.90]; women 50% vs 8%, OR, 11.23 [4.58-27.52]) (physical activity: men 67% vs 26%, OR, 5.28 [3.70-7.54]; women 66% vs 24%, OR, 5.36 [3.74-7.68]) (weight loss: men 26% vs 10%, OR, 3.05 [1.96-4.74]; women 36% vs 15%, OR, 3.08 [1.98-4.80]). For smoking and physical activity, having a consistently healthy partner also predicted positive change, but for each domain, the odds were significantly higher in individuals with a newly healthy partner than those with a consistently healthy partner (smoking: men OR, 3.08 [1.43-6.62]; women OR, 5.45 [2.44-12.16]) (physical activity: men OR, 1.92 [1.37-2.70]; women OR, 1.84 [1.33-2.53]) (weight loss: men OR, 2.28 [1.36-3.84]; women OR, 2.86 [1.55-5.26]).
Conclusions and Relevance Men and women are more likely to make a positive health behavior change if their partner does too, and with a stronger effect than if the partner had been consistently healthy in that domain. Involving partners in behavior change interventions may therefore help improve outcomes.
