Salt iodination alone is not sufficient to provide adequate iodine status to pregnant women

Objectives:
What is the prevalence of insufficient iodine intake in pregnant women from different regions of the world?

Study design:
This review article included 61 observational articles with a total of 163,021 pregnant women adults and adolescents.

Results and conclusions:
The investigators found the overall prevalence of insufficient iodine intake was 53% [95% CI = 47 to 60, I2 = 99.8%].

The investigators found pregnant women who live in insufficient iodine status country had a higher prevalence [86%, 95% CI = 78 to 93, I2 = 97.0%] of inadequate iodine nutritional status than to those living in country considered sufficient [51%, 95% IC = 45 to 57, I2 = 99.8%].

The investigators concluded despite the progress in iodine fortification policies and periodic monitoring of the iodine nutritional status of the population worldwide, salt iodination alone may not be sufficient to provide adequate iodine status to pregnant women. Thus, other actions may be necessary to improve the nutritional clinical care of pregnant group.

The iodine levels in blood can be increased through eating iodine fortified foods, like salt and/or taking iodine supplements.
