摘要

背景和目的:在全球范围内,人们对采用素食似乎越来越感兴趣。然而,有人担心,避免食用肉类可能会增加贫血和微量营养素缺乏的风险,尤其是对于弱势人群,如青少年女性。本研究的目的是比较新西兰青少年女性素食者和非素食者的微量营养素状况:方法和研究设计:从新西兰的八个地方招募了 15-18 岁的少女。对血液样本进行了以下分析:血红蛋白、血清铁蛋白、可溶性转铁蛋白受体、锌、硒、视黄醇结合蛋白、叶酸、维生素 B-12、维生素 D 和甲状旁腺激素:在提供血液样本的 182 名参与者中,15% 的人自认为是素食者(27 人)。素食者的血红蛋白平均低 3.1%(95%CI -5.8--0.4,p=0.025),硒平均低 8.3%(95%CI -14.1--2.1,p=0.004)。相比之下,血清叶酸含量为 80.5%(95%CI 45.7 至 123.7,p=0.005):青春期素食妇女缺乏动物产品中常见的微量营养素(包括锌和硒)的风险可能会增加,因此,遵循可促进微量营养素摄入和吸收的饮食习惯可能会使她们受益。

Micronutrient status of New Zealand adolescent women consuming vegetarian and non-vegetarian diets.

Background and objectives: Globally, there appears to be an ever-increasing interest in adopting a vegetarian diet. However, there are concerns that avoiding meat may increase the risk of anaemia and micronutrient deficiencies, especially for vulnerable populations, such as adolescent women. The objective of this study was to compare the micronutrient status of vegetarian and non-vegetarian adolescent women in New Zealand.

Methods and study design: Adolescent women aged 15-18 y were recruited from eight locations across New Zealand. Blood samples were analysed for: haemoglobin, serum ferritin, soluble transferrin receptor, zinc, selenium, retinol binding protein, folate, vitamin B-12, vitamin D and parathyroid hormone.

Results: Of the 182 participants who provided a blood sample, 15% self-identified as vegetarian (n=27). On average, vegetarians had 3.1% (95% CI -5.8 to -0.4, p=0.025) lower haemoglobin, and 8.3% (95%CI -14.1 to -2.1, p=0.004) lower selenium. In contrast, serum folate was 80.5% (95% CI 45.7 to 123.7, p<0.001) higher. The prevalence of zinc and selenium deficiency was higher among vegetarians (50% and 12%, respectively) than non-vegetarians (21%, and 2%, respectively).

Conclusions: Adolescent vegetarian women may be at increased risk of deficiency of micronutrients commonly found in animal products, including zinc and selenium, and may benefit from following dietary practices that enhance micronutrient intake and absorption.

期刊介绍: The aims of the Asia Pacific Journal of Clinical Nutrition (APJCN) are to publish high quality clinical nutrition relevant research findings which can build the capacity of clinical nutritionists in the region and enhance the practice of human nutrition and related disciplines for health promotion and disease prevention. APJCN will publish original research reports, reviews, short communications and case reports. News, book reviews and other items will also be included. The acceptance criteria for all papers are the quality and originality of the research and its significance to our readership. Except where otherwise stated, manuscripts are peer-reviewed by at least two anonymous reviewers and the Editor. The Editorial Board reserves the right to refuse any material for publication and advises that authors should retain copies of submitted manuscripts and correspondence as material cannot be returned. Final acceptance or rejection rests with the Editorial Board
