We carried out a review of the studies related to vitamin deficiencies in the Mexican population published since 1950. Forty four studies were published from which we can conclude that: a) dietary intake data suggest that ascorbic acid, riboflavin and retinol intake are deficient: reported intakes were 40-70%, 35-64% and 20-72% of the recommended daily amounts respectively; niacin intake was also deficient in some studies; b) about 10% of Mexican children in rural areas had deficient values of plasma retinol (< 100 ng/ml) and about 25 to 30% had low values (100-200 ng/ml); this prevalence is reduced in children with a higher socioeconomic level; c) some studies were found that show the existence of marginal deficiencies of vitamin E, riboflavin and vitamin B12 in apparently healthy populations. Further studies are required to identify the magnitude of these and perhaps other vitamin deficiencies and their potential effects on the health and function of the Mexican population.
我们对自1950年以来发表的有关墨西哥人群维生素缺乏症的研究进行了综述。共发表了44项研究，从中我们可以得出以下结论：a）膳食摄入数据表明，抗坏血酸、核黄素和视黄醇的摄入量不足：报告的摄入量分别为推荐每日摄入量的40 - 70%、35 - 64%和20 - 72%；在一些研究中，烟酸摄入量也不足；b）墨西哥农村地区约10%的儿童血浆视黄醇值偏低（< 100 ng/ml），约25%至30%的儿童视黄醇值处于低水平（100 - 200 ng/ml）；社会经济水平较高的儿童中，这种患病率有所降低；c）一些研究发现，在看似健康的人群中存在维生素E、核黄素和维生素B12的边缘性缺乏。需要进一步研究以确定这些以及可能其他维生素缺乏症的严重程度及其对墨西哥人群健康和功能的潜在影响。
