Insufficient Iodine Nutrition Common During Pregnancy

(HealthDay News) — Recent research indicates that many pregnant women have a median urinary iodine concentration below the recommended level, which may have a negative impact on the motor and cognitive functions of offspring. 

The findings were published in Acta Obstetricia et Gynecologica Scandinavica.

Michaela Granfors, MD, from Uppsala University in Sweden, and colleagues examined iodine nutrition during pregnancy in Sweden. Spot urine samples were collected in the third trimester of pregnancy for 459 pregnant, non-smoking women for median UIC analysis.

The researchers found that within the total study population, the median UIC was 98 mcg/L. According to the World Health Organization/UNICEF/Iodine Global Network criteria, the population-based median IUC during pregnancy should be 150 mcg/L to 249 mcg/L. Higher median UIC was seen for pregnant women aged younger than 30 years and obese women (BMI of at least 30) compared with older and nonobese women.

"In conclusion, the median UIC of 98 mcg/L obtained in this study population of pregnant women indicates an insufficient iodine intake in the pregnant population in Sweden," the researchers wrote. 

"This may have a negative impact on motor and cognitive functions of the offspring. There is an urgent need for national assessment of iodine status in pregnant women. More targeted intervention strategies may be needed to optimize iodine nutrition during pregnancy."
