First national iodine survey in Madagascar demonstrates iodine deficiency
AbstractUniversal salt iodization (USI) was adopted in Madagascar in 1995 within the framework of a worldwide policy to eliminate iodine deficiency disorders. Despite early USI adoption, there are no representative data on the iodine status of the Malagasy population. The aims of this study were to determine the iodine status of the Malagasy population and to assess the use of adequately iodized salt among households. We randomly sampled women of reproductive age (WRA) using a national, two ‐stage, stratified cross‐sectional survey in 2014. Casual urine from WRA and salt samples from the household containing WRA were collected to measure urinary iodine concentration (UIC) and to assess household salt iodine content. Data from 1,721 WRA in 1,128 households were collected and analyse d. The national median UIC was 46 μg L−1 (interquartile range [IQR]: 13 –98 μg L−1), indicating a moderate iodine deficiency. The median UIC was 53 μg L−1 (IQR: 9 –89 μg L−1) in pregnant women and 46 μg L−1 (IQR: 13 –98 μg L−1) in non ‐pregnant women. The national median iodine concentration of household salt was 10 mg kg−1 (IQR: 6.3 –15.8 mg kg−1) and 26.2% (95% CI [22.1, 31.0]) of households containing WRA used adequately iodized salt ( ≥15 mg kg−1). Women living in households with adequately iodized salt had higher median UIC (72 vs. 50 μg L−1). Iodine status was significantly lower among women from low socio ‐economic household...
