在随机抽样的吸烟者中调查了吸烟和社会阶层对怀孕期间饮食摄入的影响（≥ 100）。15支/d）和不吸烟者。共有206名受试者（94名吸烟者和112名非吸烟者）在妊娠28周时完成了7天的称重饮食摄入量，178名受试者在妊娠36周时完成了第二次评估。不吸烟者几乎所有营养素的摄入量都比吸烟者高，他们饮食中的营养密度也更大。不吸烟者的能量摄入量无显著性差异。社会地位较高的妇女营养摄入量最高。吸烟者比不吸烟者矮，而且往往属于较低的社会阶层。在控制了母亲的身高和社会阶层后，吸烟对许多微量营养素的摄入有显著影响。怀孕后期饮食摄入量减少，特别是吸烟者。这些数据表明，所有社会阶层的吸烟者的饮食质量都较差。
The influence of smoking and social class on dietary intake in pregnancy was investigated in a random sample of smokers (.gtoreq. 15 cigarettes/d) and nonsmokers. A total of 206 subjects (94 smokers and 112 nonsmokers) completed a 7-d weighed dietary intake at 28 wk gestation and 178 completed a second assessment at 36 wk. Nonsmokers had higher intakes of almost all nutrients than did smokers and the nutrient density of their diet was greater. Energy intake was nonsignificantly higher in nonsmokers. Women in higher social classes had the highest nutrient intakes. Smokers were shorter than nonsmokers and tended to be of lower social class. After maternal height and social class were controlled for, smoking had a significant effect on intake of many micronutrients. Dietary intake was reduced in late pregnancy, particularly in smokers. These data suggest that smokers in all social classes have a poorer quality of diet.
