目的了解上海市素食人群ω-3脂肪酸的摄入水平以及与普食人群的差异。方法通过半定量食物频率问卷法(FFQ)收集282名18～60周岁、素食1年及以上的素食者与282名同性别同年龄普食者的膳食资料,统计149种食物的摄入频率及平均每次摄入量。应用计算机R语言计算研究对象α-亚麻酸(ALA)、二十碳五烯酸(EPA)、二十二碳六烯酸(DHA)的日均膳食摄入量,以非参数检验分析素食人群与普食人群ω-3脂肪酸摄入情况的差异。结果素食人群ALA平均摄入量[(1669.00±1340.67)mg/d]显著高于普食人群[(1298.56±1041.96)mg/d];素食人群EPA平均摄入量[(8.45±12.69)mg/d]和DHA平均摄入量[(28.75±35.38)mg/d]显著低于普食人群的EPA[(128.63±144.15)mg/d]和DHA[(236.88±223.05)mg/d]。膳食中EPA和DHA主要来源于水产品。结论上海市素食人群EPA与DHA膳食摄入量显著低于普食者。
Abstract：OBJECTIVE To assess the ω-3 fatty acids intake level of vegetarians in Shanghai, and compare with the sex and age matched omnivores. METHODS The present observational study included 282 vegetarians aged 18 to 60 years old who had been vegetarian for at least one year and 282 sex and age matched omnivores recruited among Shanghai citizens. Daily food consumption was assessed through frequency and average intake of 149 kinds of food by food frequency questionnaire(FFQ) conducted by experienced dietitians. Dietary intake of ALA, EPA and DHA was calculated by R(Software). The differences of ω-3 fatty acids dietary intake between vegetarians and omnivores were analyzed with non-parametric test. RESULTS The ALA intake of vegetarian group was(1669.00±1340.67)mg/d, which was significantly higher than that of omnivore group((1298.56±1041.96)mg/d). However, the EPA intake of vegetarian group((8.45±12.69)mg/d) was significantly less than the omnivore group((128.63±144.15)mg/d). The DHA intake of vegetarian group((28.75±35.38)mg/d) was also significantly less than the omnivore group((236.88±223.05)mg/d). Most of the dietary intake of EPA and DHA was supplied by seafood. CONCLUSION Vegetarians EPA and DHA intake was significantly lower than omnivores.
