Study PeriodOctober 2019 - November 2022
Pregnancy remains a challenging period in the life of many women in low- and middle-income countries. Maternal mortality remains high and many newborns suffer from premature delivery and /or gestational growth retardation both in length and in weight accumulation.
The 2016 WHO antenatal care guidelines stated that pregnant women in undernourished populations should receive fortified balanced energy-protein (BEP) supplements to reduce the risk of stillbirth and small-for-gestational-age birth. However, acceptable supplements and delivery channels must be determined for different contexts.
The purpose of this study is to assess the efficacy of a fortified BEP supplement for pregnant and lactating women to improve birth weight, fetal and infant growth.
This research includes 2 phases:
- Phase 1 - part 1: Formative research to identify preferred product types of a fortified BEP supplement;
- Phase 1 - part 2: Formative research with a 10-week home-feeding trial to determine the acceptability of a fortified BEP supplement for longer-term consumption.
- Phase 2: A community-based, individually randomized efficacy trial of the fortified BEP food supplement including 1,776 pregnant and lactating women aimed at testing 2 hypothesis: supplementing pregnant and lactating women with a fortified BEP supplement will improve fetal growth; improving fetal growth will have a positive effect on health and growth during infancy.
- Experimental: Fortified BEP supplement Intervention: Dietary Supplement: Fortified balanced energy-protein (BEP) supplement + iron and folic acid supplement.
- Active Comparator: Fe and folic acid Dietary Supplement: Routine iron and folic acid supplementation.
