Investigating Pathways Between Maternal Nutritional Status, Breastmilk Composition, and Infant Linear Growth in Rural Pakistan

Not Applicable
Completed
Conditions
Breast Milk Collection
Infant Development
Interventions
Dietary Supplement: Multiple micronutrients (UNIMMAP composition)
Registration Number
NCT04451395
Lead Sponsor
Aga Khan University
Brief Summary

Breastmilk is considered optimal for infant growth and development. However, evidence suggests that breastmilk composition can vary according to maternal nutritional status. Among women in Pakistan, there is a high burden of undernutrition and micronutrient deficiencies. As well, the prevalence of early stunting among Pakistani infants is high. Using a hypothesized pathway model, this study will assess pathways between maternal nutritional status, breastmilk composition, and infant linear growth. This is a substudy to the Matiari emPowerment and Preconception Supplementation (MaPPS) Trial (ClinicalTrials.gov Identifier: NCT03287882).

Multiple micronutrients (UNIMMAP composition)Multiple micronutrients (UNIMMAP composition)The intervention is an oral tablet containing 15 different vitamins and minerals at the UNIMMAP composition (includes 30 mg iron, 400 μg folic acid, 15 mg zinc, 2 mg copper, 65 μg selenium, 800 μg RE vitamin A, 1.4 mg vitamin B1, 1.4 mg vitamin B2, 18 mg niacin, 1.9 mg vitamin B6, 2.6 μg vitamin B12, 70 mg vitamin C, 5 μg vitamin D, 10 mg vitamin E and 150 μg iodine). Each tablet is small (approximately 10 mm diameter) and has been procured using the UNICEF supply catalogue. A single MMN supplementation dose will consist of a single tablet..The supplement is provided within the parent trial. Other Name: UNICEF, Micronutrient tabs, pregnancy/PAC-1000
