Smoking is a major risk factor in the development of preventable disease which may be due to a poorer diet and the reduced nutrient intake of smokers. Our objective was to compare and evaluate the reported intake of current smokers with that of nonsmokers among participants of a study evaluating stress and smoking. We hypothesized (1) that overall energy and nutrient intake would be reduced in smokers compared with nonsmokers and (2) that smokers would have increased noncompliance with Dietary Reference Intakes (DRIs). Men and women (smokers n=138, nonsmokers n=46) completed a 3-day diet record at baseline. Mean energy and nutrient intakes were stratified by smoking status and compared with DRI levels. The mean body mass index was 28.3±0.5kg/m for smokers and 27.2±1.0kg/m for nonsmokers. Compared with nonsmokers, the smokers reported lower intakes of energy, total polyunsaturated fatty acids, linolenic acid, docosahexaenoic acid, total sugars, calcium, iron, magnesium, phosphorus, potassium, vitamin C, riboflavin, niacin, pantothenic acid, vitamin B6, folate, vitamin A, and vitamin E. Smokers reported reduced compliance with the DRIs for iron, phosphorus, vitamin C, riboflavin, and folate compared with nonsmokers. Unlike other evaluations of smokers vs nonsmokers, we observed no difference in body weight between groups. Smokers and nonsmokers alike reported dietary intakes lower than the DRIs for many nutrients. However, the reported nutrient intake of the smokers was substantially lower than nonsmokers for key nutrients, and they were more likely to not comply with the DRIs for essential nutrients, placing them at increased risk of chronic disease.
吸烟是导致可预防疾病的主要危险因素,这可能是由于吸烟者饮食较差且营养素摄入减少所致。我们的目的是比较和评估评估压力与吸烟的研究参与者中当前吸烟者和非吸烟者的报告摄入量。我们假设(1)与非吸烟者相比,吸烟者的总能量和营养素摄入会减少;(2)吸烟者对膳食参考摄入量(DRIs)的依从性会增加。男性和女性(吸烟者 n=138,非吸烟者 n=46)在基线时完成了 3 天的饮食记录。按吸烟状况对平均能量和营养素摄入量进行分层,并与 DRI 水平进行比较。吸烟者的平均体重指数为 28.3±0.5kg/m,非吸烟者为 27.2±1.0kg/m。与非吸烟者相比,吸烟者报告的能量、总多不饱和脂肪酸、亚麻酸、二十二碳六烯酸、总糖、钙、铁、镁、磷、钾、维生素 C、核黄素、烟酸、泛酸、维生素 B6、叶酸、维生素 A 和维生素 E 的摄入量较低。与非吸烟者相比,吸烟者报告的铁、磷、维生素 C、核黄素和叶酸对 DRI 的依从性降低。与其他对吸烟者与非吸烟者的评估不同,我们观察到两组间的体重没有差异。吸烟者和非吸烟者均报告称,他们的饮食摄入量低于 DRI 规定的许多营养素。然而,与非吸烟者相比,吸烟者报告的关键营养素的摄入量要低得多,而且他们更有可能不遵守基本营养素的 DRI,从而使他们面临更高的慢性病风险。
