Abstract

Based on new evidence and lessons learned within the last decade, pregnant women may not receive adequate iodized salt where the coverage of universal salt iodisation is poor. World Health Organisation has stated this could jeopardize optimal brain development of the fetus. This study was aimed to assess the iodine status of pregnant women in Sri Lanka. A cross-sectional clinic based nationally representative study was conducted. Three randomly selected antenatal clinics from each province, 30 randomly selected pregnant women from each selected clinic were included in the study. A total of 739 pregnant women were studied and casual urine samples collected to estimate iodine levels. Median urinary iodine levels in pregnant women was 113.7 g/L, which is far below the WHO recommendation between 150 and 249 μg/L indicating inadequate iodine status of pregnant women in Sri Lanka. Urine iodine distribution indicated 61.3%, 21.7%, 15.2% and 1.8% of pregnant women had an inadequate, adequate, above requirement and excessive intake respectively. Urinary iodine concentration significantly decreased with advancing pregnancy. Inadequate iodine intake was evident in 47.4%, 60.2% and 68.8% of pregnant women in the first, second and third trimester respectively. In conclusion, there is an urgent need to identify a programme to provide adequate iodine to pregnant women to ensure optimum fetal brain development.
