금연과 다이어트에 어려움을 겪고 있다면 배우자나 연인의 도움을 받는 것이 좋다는 연구 결과가 나왔다.    영국 유니버시티칼리지런던(UCL) 연구팀은 부부를 포함한 커플 3722쌍을 대상으로 금연과 운동 등을 함께 진행하면 성공률이 어떻게 달라지를 알아봤다.     금연의 경우 커플이 함께 시도했을 때 절반가량의 참가자가 성공했다. 하지만 흡연자인 배우자나 연인이 옆에서 계속 담배를 피울 경우 흡연자 중 8% 정도만 담배를 끊었다.    운동을 할 때도 커플이 함께하는 경우가 오래 운동을 즐길 수 있는 것으로 나타났다. 커플이 함께 하는 경우에는 60% 이상이 실험기간 동안 꾸준히 운동을 이어나갔지만, 배우자나 연인이 함께 운동하지 않은 경우에는 남성은 26%, 여성은 24%만 운동을 계속했다.     다이어트도 커플이 같이 할 때 성공률은 30% 정도 됐지만 홀로 다이어트를 시도한 경우 체중을 감량한 사람은 10% 정도였다.    연구결과는 의학 학술지 ‘JAMA 내과학’ 20일자에 실렸다.  동아사이언스 신선미 기자 vamie@donga.com

The English Longitudinal Study of Ageing 

Sarah E. Jackson, PhD1; Andrew Steptoe, DSc2; Jane Wardle, PhD 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. http://archinte.jamanetwork.com/article.aspx?articleid=2091401
