作者在《肺健康研究》(1986-1994)中对5年随访期内与戒烟有关的体重增加进行了研究。美国和加拿大的5887名男性和女性吸烟者，年龄在35岁到60岁之间，他们被随机分为吸烟干预组和常规护理组。在持续戒烟5年的参与者中，女性在第一年的平均体重增加了5.2(标准差，5.0)公斤，在1-5年的平均体重增加了3.4(标准差，5.5)公斤。男性在第一年的平均体重增加了4.9(标准误差，4.9)公斤，在1-5岁的平均体重增加了2.6(标准误差，5.8)公斤。在回归分析中，吸烟变化变量是体重变化最有效的预测因子。从吸烟到戒烟的参与者在给定的一年中，男性的平均体重增加了2.95公斤/年(3.61%)，女性的体重增加了3.09公斤/年(4.69%)。5年来，33%的持续戒烟者体重增加超过或等于10公斤，而持续吸烟者的这一比例为6%。此外，在持续戒烟者中，7.6%的男性和19.1%的女性体重增加超过或等于基线体重的20%；60%的增加发生在第一年，尽管体重显著增加持续到第五年。持续和间歇性戒烟者体重超标的平均增加和高比例表明，需要更有效的早期干预措施，同时解决戒烟和体重控制问题。
The authors examine weight gains associated with smoking cessation in the Lung Health Study (1986-1994) over a 5-year follow-up period. A cohort of 5,887 male and female smokers in the United States and Canada, aged 35-60 years, were randomized to either smoking intervention or usual care. Among participants who achieved sustained quitting for 5 years, women gained a mean of 5.2 (standard error, 5.0) kg in year 1 and a mean of 3.4 (standard error, 5.5) kg in years 1-5. Men gained a mean of 4.9 (standard error, 4.9) kg in year 1 and a mean of 2.6 (standard error, 5.8) kg in years 1-5. In regression analyses, smoking-change variables were the most potent predictors of weight change. Participants going from smoking to quit-smoking in a given year had mean weight gains of 2.95 kg/year (3.61 %) in men and 3.09 kg/year (4.69%) in women. Over 5 years, 33% of sustained quitters gained greater than or equal to 10 kg compared with 6% of continuing smokers. Also among sustained quitters, 7.6% of men and 19.1% of women gained greater than or equal to 20% of baseline weight; 60% of the gain occurred in year 1, although significant weight gains continued through year 5. The average gains and the high proportions of sustained and intermittent quitters who gained excessive weight suggest the need for more effective early interventions that address both smoking cessation and weight control.
