Diet, smoking, social class, and body mass index in the Caerphilly Heart Disease Study.
Associations between smoking habit, social class, body mass index, and diet were examined in 493 men aged 45 to 59 yr, selected from the general population and who had completed a 7-day weighed dietary record. Smokers were lighter than nonsmokers and had a lower body mass index. There was no difference in energy intake, but in general, smokers had lower intakes of vitamins, minerals, and dietary fiber. Exsmokers had similar intakes to nonsmokers. Manual workers tended to be shorter, had a higher body mass index, higher intakes of energy and carbohydrates, and lower intakes of vitamins and minerals than nonmanual workers. Social class had a greater effect than smoking habit on intakes of energy and carbohydrates, whereas smoking habit had the greater effect on intakes of minerals and vitamins. Body mass index was associated negatively with sucrose intake and positively with protein intake, smoking habit, and social class being less important determinants.
