Abstract

OBJECTIVE

To evaluate the association of iodine nutrition status and knowledge, attitude, and behavior in Tehranian women after 2 decades without updating public education.

DESIGN

Cross-sectional study.

SETTING

Eight health care centers from 4 district areas of Tehran.

PARTICIPANTS

A total of 383 women aged ≥ 19 years, randomly selected.

MAIN OUTCOME MEASURES

Iodine concentration of 24-hour urine samples, iodine content of household salts, and knowledge, attitude, and practice scores regarding iodine nutrition and iodized salt.

ANALYSIS

Multiple logistic regression was used to identify the association of knowledge, attitude, and practice scores with urinary iodine concentration (UIC) < 100 μg/L.

RESULTS

The percentages of Tehranian women with high knowledge, attitude, and practice scores were 26%, 26%, and 14%, respectively. Practice score was significantly different between females with UIC < 100 and > 100 μg/L (P = .001). Risk of UIC < 100 μg/L in women of childbearing age (19-45 years) after adjustment of education level, region of residence, and iodine content of salt was significantly associated with intermediate practice score (odds ratio = 2.6; 95% confidence interval, 1.3-13.2).

CONCLUSIONS AND IMPLICATIONS

Marginally suboptimal iodine status in women of childbearing age can be attributed to inappropriate practices, but not to knowledge and attitude.

摘要

目的

评估在 20 年未更新公众教育的情况下，德黑兰女性的碘营养状况与知识、态度和行为之间的关联。

设计

横断面研究。

地点

德黑兰 4 个区的 8 个医疗中心。

参与者

共随机抽取 383 名年龄≥19 岁的女性。

主要观察指标

24 小时尿样中的碘浓度、家庭用盐中的碘含量以及关于碘营养和碘盐的知识、态度和实践评分。

分析

采用多因素逻辑回归分析知识、态度和实践评分与尿碘浓度（UIC）<100μg/L 之间的关联。

结果

高知识、高态度和高实践评分的德黑兰女性比例分别为 26%、26%和 14%。实践评分在 UIC<100μg/L 和 UIC>100μg/L 的女性之间存在显著差异（P=0.001）。调整教育水平、居住地区和盐的碘含量后，处于生育年龄（19-45 岁）的女性 UIC<100μg/L 的风险与中等实践评分显著相关（比值比=2.6；95%置信区间，1.3-13.2）。
