Latin American countries have shifted from traditional diets rich in micronutrients to a Westernized diet rich in high energy-dense foods and low in micronutrients.
This study aimed to determine the prevalence of adequate micronutrient intakes in urban populations of 8 Latin American countries.
Micronutrient dietary intake data were collected from September 2014 to August 2015 from 9216 men and women aged 15.0 to 65.0 years living in urban populations of 8 Latin American countries. Dietary intake was collected using two 24-hour recalls on nonconsecutive days. Micronutrient adequacy of intake was calculated using the Estimated Average Requirement cut-off method.
In general terms, the prevalence of inadequate intake of thiamine, riboflavin, niacin, folate, cobalamin, iron, phosphorus, copper, and selenium ranged from 0.4% to 9.9%. In contrast, the prevalence of inadequacy of pyridoxine, zinc, vitamin C, and vitamin A ranged from 15.7% to 51.5%. The nutrients with a critical prevalence of inadequacy were magnesium (80.5%), calcium (85.7%), and vitamin D (98.2%). The highest prevalence of inadequate intakes was observed in the low educational level, participants with overweight/obesity, in men, and varies according to socioeconomic status.
There is an urgent need to define direct regional actions and strategies in Latin America aimed at improving micronutrient adequacy, either through staple food fortification programs, agronomic biofortification, or food policies that facilitate economic access to micronutrient-rich foods.
拉丁美洲国家已从富含微量营养素的传统饮食转变为富含高热量、低微量营养素的西式饮食。
本研究旨在确定 8 个拉丁美洲国家城市人口中微量营养素充足摄入量的流行情况。
2014 年 9 月至 2015 年 8 月,从 8 个拉丁美洲国家城市人口中 15.0 至 65.0 岁的 9216 名男性和女性收集微量营养素饮食摄入数据。使用两天非连续的 24 小时回忆法收集饮食摄入数据。采用估计平均需求量(EAR)截断法计算微量营养素摄入的充足程度。
总体而言,硫胺素、核黄素、烟酸、叶酸、钴胺素、铁、磷、铜和硒摄入不足的发生率在 0.4%至 9.9%之间。相比之下,吡哆醇、锌、维生素 C 和维生素 A 摄入不足的发生率在 15.7%至 51.5%之间。镁(80.5%)、钙(85.7%)和维生素 D(98.2%)是微量营养素摄入不足的关键营养素。低教育水平、超重/肥胖、男性和不同社会经济地位的参与者中,摄入不足的发生率最高。
拉丁美洲迫切需要制定直接的区域行动和战略,旨在通过主食强化计划、农业生物强化或促进经济获取富含微量营养素食物的食品政策,改善微量营养素的充足程度。
