The aim of the present study was to examine the association between smoking status and relative body weight at different educational levels in Finland during 1978-1995.
The data for the study were derived from separate cross-sectional health behavior surveys conducted annually by the National Public Health Institute (n = 3,418-5,037, response rate 68-84%). Relative weight was compared among current smokers, ex-smokers, and never smokers. Mean body mass index (BMI) was used as the measure of relative weight. Educational level was measured by the number of school years.
During 1978-1995, relative weight increased in all smoking categories. Among men, ex-smokers weighed most, irrespective of study year or educational level, whereas among women ex-smokers showed a mean BMI comparable with that of never smokers. Among current and never smokers, both men and women, the association between smoking status and mean BMI varied according to educational level: current smokers weighed less than never smokers at the lowest educational level, whereas at the highest educational level they weighed more than never smokers.
The association between smoking status and relative weight varied according to educational level. The finding suggests that the association between smoking status and relative weight is modified by social and behavioral factors.
本研究旨在探讨1978年至1995年期间芬兰不同教育水平人群的吸烟状况与相对体重之间的关联。
本研究数据来自国家公共卫生研究所每年进行的单独横断面健康行为调查（n = 3418 - 5037，应答率68% - 84%）。比较了当前吸烟者、既往吸烟者和从不吸烟者的相对体重。平均体重指数（BMI）用作相对体重的衡量指标。教育水平通过上学年数来衡量。
1978年至1995年期间，所有吸烟类别中的相对体重均有所增加。在男性中，无论研究年份或教育水平如何，既往吸烟者体重最重，而在女性中，既往吸烟者的平均BMI与从不吸烟者相当。在当前吸烟者和从不吸烟者中，无论男性还是女性，吸烟状况与平均BMI之间的关联因教育水平而异：在最低教育水平上，当前吸烟者体重低于从不吸烟者，而在最高教育水平上，他们的体重高于从不吸烟者。
吸烟状况与相对体重之间的关联因教育水平而异。这一发现表明，吸烟状况与相对体重之间的关联受到社会和行为因素的影响。
