Randomized Controlled TrialDaily Consumption of Lipid-Based Nutrient Supplements Containing 250 μg Iodine Does Not Increase Urinary Iodine Concentrations in Pregnant and Postpartum Women in Bangladesh.
Background: Maternal iodine deficiency during pregnancy and lactation is common in Bangladesh. Objective: We evaluated the effect of lipid-based nutrient supplements for pregnant and lactating women (LNS-PL) on urinary iodine concentration (UIC). Methods: We conducted a cluster-randomized controlled effectiveness trial in which we enrolled 4011 pregnant women at ≤20 gestational weeks. ⋯ Iodine from lipid-based nutrient supplements may have been stored in the thyroid gland or secreted in breast milk instead of being excreted in urine. Additional research that uses other biomarkers of iodine status is needed to determine how to meet the iodine requirements of pregnant and lactating women in Bangladesh and similar settings. This trial was registered at clinicaltrials.gov as NCT01715038.

After Mexico Implemented a Tax, Purchases of Sugar-Sweetened Beverages Decreased and Water Increased: Difference by Place of Residence, Household Composition, and Income Level.
Background: In January 2014, Mexico implemented a tax on sugar-sweetened beverage (SSB) purchases of 1 peso/L. Objective: We examined the heterogeneity of changes in nonalcoholic beverage (SSB and bottled water) purchases after the tax was implemented by household income, urban and rural strata, and household composition. Methods: We used 4 rounds of the National Income and Expenditure Surveys: 2008, 2010, 2012, and 2014. ⋯ We also found a 16.2% increase in water purchases that was higher in low- and middle-income households, in urban areas, and among households with adults only. Conclusions: SSB purchases decreased and water purchases increased after an SSB tax was imposed in Mexico. The magnitude of these changes was greater in lower-income and urban households.
