A large-scale survey of steel workers in South Wales has shown a considerable difference between the body weights of smokers and of non-smokers. The difference increases with age so that men over 40 years who have never smoked are on average 13 lb (5.9 kg) heavier than smokers. Even so, smokers are about 15 lb (6.8 kg) heavier than the weight standard considered desirable by the Metropolitan Life Insurance Company, while non-smokers are nearly 30 lb (13.6 kg) heavier.About 20% of the men are attempting to give up the smoking habit. Ex-smokers who have given up smoking for more than eight years approach the body weight of men of the same age who have never smoked.Many reports have been published on the health consequences of smoking and of obesity. Because smoking and obesity are inversely related studies of the interrelation of these two health hazards and of their relative importance are needed.
对南威尔士钢铁工人的一项大规模调查显示，吸烟者和非吸烟者的体重存在显著差异。这种差异随着年龄的增长而增大，以至于40岁以上从未吸烟的男性平均比吸烟者重13磅（5.9千克）。即便如此，吸烟者的体重比大都会人寿保险公司认为理想的体重标准重约15磅（6.8千克），而非吸烟者则比该标准重近30磅（13.6千克）。约20%的男性正试图戒烟。戒烟超过八年的前吸烟者的体重接近同龄从未吸烟男性的体重。关于吸烟和肥胖对健康影响的报告众多。由于吸烟与肥胖呈负相关，因此需要对这两种健康危害的相互关系及其相对重要性进行研究。
