目的 :研究吸烟对人饮食行为的影响。方法 :随机抽取一个社区 30～ 6 0岁成年男子共 187人 ,按是否吸烟分为两组 ,进行饮食行为和膳食的调查 ,并测定血脂和脂质过氧化物。结果 :吸烟组每日吃肥猪肉 (或肥瘦猪肉 )或动物油 ,经常饮酒 ,每日蔬菜水果 <2 5 0克 ,脂肪占热能比 >30 %的人数明显多于非吸烟组 (P<0 .0 5～ 0 .0 1)。吸烟组平均血清 TC、 TG和 L PO水平也明显高于非吸烟组 (P<0 .0 5 ,0 .0 1和 0 .0 5 ) ;吸烟组高血脂症者 35人 ,而非吸烟组只有 12人 ,差别有显著意义 (P<0 .0 5 )。结论 :吸烟 ,尤其是长期吸烟 ,易导致动物脂肪摄入过多 ,喜爱饮酒 ,而蔬菜水果与谷类摄入过少 Objective: To study the influence of smoking on human dietary behavior. Methods: A total of 187 adult men aged 30 ~ 60 years were randomly selected from the community and divided into two groups according to whether they smoked. Their dietary behaviors and diet were investigated. Blood lipids and lipid peroxides were also measured. Results: In the smoking group, the daily consumption of pork (or fat lean pork) or animal oil often consumed alcohol. The daily intake of fruits and vegetables was less than 250 g, and the percentage of fat in the proportion of thermal energy> 30% was significantly higher than that in non-smoking group (P <0. 0 5 ~ 0 .0 1). The mean levels of TC, TG and L PO in smokers were also significantly higher than those in non-smokers (P <0.05, 0.01 and 0.05), while those in smokers were 35 Only 12 people, the difference was significant (P <0. 05). Conclusion: Smoking, especially long-term smoking, can easily lead to excessive intake of animal fat, drinking alcohol, and too little intake of fruits, vegetables and cereals
