摘要

本研究的范围是根据生化和饮食标记来描述巴西孕妇的碘营养状况。该研究对2376名孕妇进行了横断面研究。采用半结构化问卷来描述人群特征。收集尿液样本以调查碘营养状况,并采用24小时召回法评估食物消耗。统计分析采用Shapiro-Wilk检验验证正态分布,并进行描述性分析。尿碘中位浓度(UIC)为186.6µg/L。碘缺乏率为36.7%,碘过量率为28.7%,碘缺乏率为3.6%。食盐中碘浓度中位数为26.6 mg/kg,调味料中为1.1 mg/ 100g,水中为2.9µg/L,新鲜食品中为19.4µg/ 100g。平均碘摄入量为160.2µg。在评估饮食摄入量时,49.8%的孕妇习惯性碘摄入量低于160微克,没有人摄入过量。得出的结论是,中位UIC显示出足够的碘营养状况,尽管观察到碘缺乏和过量的高发率。此外,碘营养状况各不相同,这可能反映了社会经济和健康的不平等。

Iodine nutritional status of pregnant Brazilian women according to biochemical and dietary markers: EMDI-Brasil study.

The scope of this study was to characterize the iodine nutritional status of pregnant Brazilian women according to biochemical and dietary markers. It involved a cross-sectional study of 2,376 pregnant women. A semi-structured questionnaire was used to characterize the population. Urine samples were collected to investigate iodine nutritional status, and a 24-hour recall was used to assess food consumption. For the statistical analysis, the Shapiro-Wilk test was applied to verify the normality pattern, and descriptive analyses were conducted. The median urinary iodine concentration (UIC) was 186.6 µg/L. There was a 36.7% prevalence of iodine deficiency, 28.7% of iodine excess and 3.6% of iodine deficiency. The median iodine concentration was 26.6 mg/kg in salt, 1.1 mg/100 g in seasonings, 2.9 µg/L in water and 19.4 µg/100 g in fresh food. The average iodine intake was 160.2 µg. When assessing dietary intake, 49.8% of the pregnant women had a habitual iodine intake below 160 µg and none had an excessive intake. The conclusion drawn is that the median UIC showed adequate iodine nutritional status, though a high prevalence of iodine deficiency and excess was observed. In addition, iodine nutritional status varied, which may reflect socioeconomic and health inequalities.
