Item Consumption of multiple micronutrients or small-quantity lipid-based nutrient supplements containing iodine at the recommended dose during pregnancy, compared with iron and folic acid, does not affect women’s urinary iodine concentration in rural Malawi: a secondary outcome analysis of the iLiNS DYAD trial(Public Health Nutrition, 2021) Adu-Afarwuah, S.; Arnold, C.D.; Maleta, K.; Ashorn, P.; Ashorn, U.; Jorgensen, J.M.; Fan, Y.; Nkhoma, M.; Bendabenda, J.; Matchado, A.; Dewey, K.G.Objectives: Inadequate iodine intake during pregnancy increases the risk of neo natal morbidity and mortality. We aimed to evaluate whether prenatal supplements containing iodine affect urinary iodine concentrations (UIC) of pregnant women in Malawi. Design: A randomised controlled trial. Pregnant women (n 1391) were assigned to consume 60 mg/d Fe and 400 μg/d folic acid (IFA) or 18 vitamins and minerals including 250 μg/d iodine (MMN) or 20 g/d small-quantity lipid-based nutrient sup plements (SQ-LNS) with similar nutrient contents as MMN group, plus macronu trients (LNS) until childbirth. In a sub-study (n 317), we evaluated group geometric mean urinary iodine concentration (UIC) (μg/L) at 36 weeks of gestation controlling for baseline UIC and compared median (baseline) and geometric mean (36 weeks) UIC with WHO cut-offs: UIC < 150, 150–249, 250–499 and ≥500 reflect ing insufficient, adequate, above requirements and excessive iodine intakes, respectively. Setting: Mangochi District, Malawi. Participants: Women ≤20 weeks pregnant. Results: Groups had comparable background characteristics. At baseline, overall median (Q1, Q3) UIC (319 (167, 559)) suggested iodine intakes above require ments. At 36 weeks, the geometric mean (95 % CI) UIC of the IFA (197 (171, 226)), MMN (212 (185, 243)) and LNS (220 (192, 253)) groups did not differ (P = 0·53) and reflected adequate intakes. Conclusions: In this setting, provision of supplements containing iodine at the rec ommended dose to pregnant women with relatively high iodine intakes at base line, presumably from iodised salt, has no impact on the women’s UIC. Regular monitoring of the iodine status of pregnant women in such settings is advisable. Clinicaltrials.gov identifier: NCT01239693.Item Predictors and pathways of language and motor development in four prospective cohorts of young children in Ghana, Malawi, and Burkina Faso(Journal of Child Psychology and Psychiatry and Allied Disciplines, 2017-11) Prado, E.L.; Abbeddou, S.; Adu-Afarwuah, S.; Arimond, M.; Ashorn, P.; Ashorn, U.; Bendabenda, J.; Brown, K.H.; Hess, S.Y.; Kortekangas, E.; Lartey, A.; Maleta, K.; Oaks, B.M.; Ocansey, E.; Okronipa, H.; Ouédraogo, J.B.; Pulakka, A.; Somé, J.W.; Stewart, C.P.; Stewart, R.C.; Vosti, S.A.; Yakes Jimenez, E.; Dewey, K.G.Background: Previous reviews have identified 44 risk factors for poor early child development (ECD) in low- and middle-income countries. Further understanding of their relative influence and pathways is needed to inform the design of interventions targeting ECD. Methods: We conducted path analyses of factors associated with 18-month language and motor development in four prospective cohorts of children who participated in trials conducted as part of the International Lipid-Based Nutrient Supplements (iLiNS) Project in Ghana (n = 1,023), Malawi (n = 675 and 1,385), and Burkina Faso (n = 1,122). In two cohorts, women were enrolled during pregnancy. In two cohorts, infants were enrolled at 6 or 9 months. In multiple linear regression and structural equation models (SEM), we examined 22 out of 44 factors identified in previous reviews, plus 12 additional factors expected to be associated with ECD. Results: Out of 42 indicators of the 34 factors examined, 6 were associated with 18-month language and/or motor development in 3 or 4 cohorts: child linear and ponderal growth, variety of play materials, activities with caregivers, dietary diversity, and child hemoglobin/iron status. Factors that were not associated with child development were indicators of maternal Hb/iron status, maternal illness and inflammation during pregnancy, maternal perceived stress and depression, exclusive breastfeeding during 6 months postpartum, and child diarrhea, fever, malaria, and acute respiratory infections. Associations between socioeconomic status and language development were consistently mediated to a greater extent by caregiving practices than by maternal or child biomedical conditions, while this pattern for motor development was not consistent across cohorts. Conclusions: Key elements of interventions to ensure quality ECD are likely to be promotion of caregiver activities with children, a variety of play materials, and a diverse diet, and prevention of faltering in linear and ponderal growth and improvement in child hemoglobin/iron status. © 2017 The Authors.
