Insufficient iodine intake in pregnant women in different regions of the world: a systematic review

Abstract: Objective:To determine the prevalence of insufficient iodine intake in pregnant women. Materials and methods: The search was performed in the electronic databases Medline (PubMed), Latin American and Caribbean Literature in Health Sciences (Lilacs) and Scopus. Review studies, experimental studies, those with adolescent pregnant women (< 20 years) and iodine supplementation were excluded. The selection followed the steps of identifying the articles in the databases, deleting the duplicates, and reading the titl… Show more

“…In Europe, according to a 2015 estimate, women in approximately two-thirds of countries with available data were iodine de icient during pregnancy [18]. Additionally, a recent systematic review of 13 studies by Candido, et al from different regions of the world, including 14,042 pregnant women showed that the prevalence of insuf icient iodine status ranged from 16.1 to 84.0%, and the median of iodine intake was insuf icient in 75% of the studies [19]. It is reported that in some iodine suf icient countries like USA, Japan, Iran, Austria, England, Norway, Italy, Sweden and etc.…”

“…Historically iodine deficiency was thought to be more likely found in mountainous regions and areas exposed to frequent flooding (20). However, available data worldwide over the past two decades show that iodine deficiency is not restricted to those areas, and has been reported in different places around the world, including industrialized countries (21).…”

“…Additionally, a recent systematic review of 13 studies from different regions of the world, including 14,042 pregnant women showed that the prevalence of insufficient iodine status ranged from 16.1 to 84.0%, and the median of iodine intake was insufficient in 75% of the studies (20). However, as there is no classification for mild, moderate, or severe iodine deficiency in pregnant women, it is difficult to portray the severity of this problem.…”

“…regarding iodine deficiency) and environmental (p.ex. regarding type of pollutants exposed to) differences do exist among these populations [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. The environmental degradation, which has occurred in recent years in urban and suburban settings in Greece [ 20 ], led us to the localized study of air pollution vs. thyroid status in pregnant women in Athens, Greece.…”
