Thirty years after folic acid was shown to be effective in reducing SBA prevalence, only about one-quarter of such births are prevented globally through cereal grain fortification.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>To determine the association of folic acid\u2013fortified iodized salt with serum folate concentrations among nonpregnant and nonlactating women of reproductive age.<\/jats:p><\/jats:sec><jats:sec><jats:title>Design, Setting, and Participants<\/jats:title><jats:p>This nonrandomized controlled trial using a preintervention and postintervention design was conducted in 4 rural villages in Southern India from July 1  to November 30, 2022. All households in the villages agreed to participate in the study.

The median serum folate concentration increased from 14.6 (IQR, 11.2-20.6) nmol\/L at baseline to 54.4 (IQR, 43.5-54.4) nmol\/L at end of study, a 3.7-fold increase from baseline to study end point. Two-tailed Wilcoxon signed rank test showed the median difference in preintervention and postintervention serum folate concentrations to be highly significant (<jats:italic>P<\/jats:italic>\u2009&amp;amp;lt;\u2009.001).
