To determine whether adult non-vegetarian Seventh-day Adventists differ in selected nutrition related health aspects from adult vegetarian Seventh-day Adventists.
One hundred and forty-one Seventh-day Adventist church members responded to a general health questionnaire. Forty-seven sex and age matched subjects (23 non-vegetarians and 24 vegetarians) were selected for further investigation. Blood lipids, serum vitamin B12, folate, haemoglobin and ferritin levels were measured along with stature, weight and blood pressure. A quantitative 7-day diet record was also completed.
Body mass index was similar between the non-vegetarian and vegetarian groups but diastolic blood pressure was higher for non-vegetarian than vegetarian males. Even though the dietary vitamin B12 intake was significantly lower (p < 0.01) in the vegetarian group both vegetarians and non-vegetarians recorded similar serum vitamin B12 levels. The vegetarian and non-vegetarian groups had similar haemoglobin concentrations. While dietary iron intake was higher in the female vegetarian group, though predominantly in the non-haem form, the difference was not significant. Low serum ferritin levels were found in both female dietary groups even though the vegetarian group had a significantly (p < 0.05) higher vitamin C intake. Blood lipid levels were similar in the two diet groups even though the vegetarian group had a lower percentage energy contribution from total and saturated fat (p < 0.01) and consumed significantly less cholesterol.
Both non-vegetarian and vegetarian Seventh-day Adventists appear likely to enjoy a lower risk of nutrition related chronic degenerative disease than the average New Zealander and have a satisfactory iron and vitamin B12 status.
确定成年非素食基督复临安息日会信徒在某些与营养相关的健康方面是否与成年素食基督复临安息日会信徒存在差异。
141名基督复临安息日会教堂成员对一份一般健康问卷进行了回应。选择了47名性别和年龄匹配的受试者（23名非素食者和24名素食者）进行进一步调查。测量了血脂、血清维生素B12、叶酸、血红蛋白和铁蛋白水平，同时测量了身高、体重和血压。还完成了一份7天的定量饮食记录。
非素食组和素食组的体重指数相似，但非素食男性的舒张压高于素食男性。尽管素食组的膳食维生素B12摄入量显著较低（p<0.01），但素食者和非素食者的血清维生素B12水平相似。素食组和非素食组的血红蛋白浓度相似。虽然女性素食组的膳食铁摄入量较高，尽管主要是非血红素形式，但差异不显著。两个女性饮食组的血清铁蛋白水平都较低，尽管素食组的维生素C摄入量显著较高（p<0.05）。两个饮食组的血脂水平相似，尽管素食组来自总脂肪和饱和脂肪 的能量贡献百分比较低（p<0.01），且胆固醇摄入量显著较少。
与普通新西兰人相比，非素食和素食的基督复临安息日会信徒似乎都有较低的与营养相关的慢性退行性疾病风险，并且铁和维生素B12状况良好。
