The relationship between smoking and weight was examined in data of Lipid Research Clinic (LRC) Prevalence Study in Richfield, Minnesota. Weight was analyzed according to smoking status, age, and sex, holding constant self-perceived physical activity relative to others of the same age and sex. Our findings confirm that weight differences between smokers of 15-29 cigarettes a day (cig/day) and those who never smoked are noticeable in 20-39 year olds and quite marked in the 40-59 year age group. Ex-smokers are somewhat heavier than those who never smoked while, among smokers, a U-shaped curve exists with those smoking 15-29 cig/day being the lightest class. Height varied little between smoking classes. Daily caloric intake was estimated based on 24-hour dietary recalls and analyzed according to smoking status, sex, and age. The results showed that smokers of 15-29 cig/day generally are consuming at least as many or more calories as those who never smoked yet have lower weight.
在明尼苏达州里奇菲尔德进行的脂质研究诊所（LRC）患病率研究数据中，对吸烟与体重之间的关系进行了考察。根据吸烟状况、年龄和性别对体重进行分析，同时保持与同年龄、同性别的其他人相比的自我感知身体活动量不变。我们的研究结果证实，每天吸15 - 29支烟（支/天）的吸烟者与从不吸烟的人之间的体重差异在20 - 39岁人群中较为明显，在40 - 59岁年龄组中则相当显著。已戒烟者比从不吸烟的人稍重一些，而在吸烟者中，存在一条U形曲线，每天吸15 - 29支烟的人是体重最轻的类别。不同吸烟类别之间身高变化不大。根据24小时饮食回忆估算每日热量摄入，并根据吸烟状况、性别和年龄进行分析。结果显示，每天吸15 - 29支烟的吸烟者通常摄入的热量至少与从不吸烟的人一样多或更多，但体重却更低。
