Primary Outcome Measures:
  • Neonatal linear growth [ Time Frame: <24 hours of age ] [ Designated as safety issue: No ]
    Research assistants will obtain neonatal length measurement at <24 hours of age.


Secondary Outcome Measures:
  • Length-for-age Z-scores [ Time Frame: age 0.5, 1, 3 and 6 months postnatal ] [ Designated as safety issue: No ]
    Research assistants will obtain infant anthropometry measurements, which include length, head circumference, triceps skin folds, Mid Upper Arm Circumference (MUAC), and weight, at age 0.5, 1, 3, and 6 months of age. Length-for-age Z-scores will be compared for offspring of mothers randomized to the three intervention arms.

  • Estimate fetal growth [ Time Frame: 12 weeks gestation ] [ Designated as safety issue: No ]
    Ultrasound measurements will be undertaken at 12 weeks gestation with the goals of confirming gestational age and estimating fetal growth.

  • Mean birth weight and incidence of low birth weight (LBW) infants [ Time Frame: at birth ] [ Designated as safety issue: No ]
    As a dichotomous variable, the cutoff of 2500 g does not have the power of the continuum of birth length, but is included because of the long history of use in determining which newborns are severely underweight and this association with impaired neonatal and long-term prognosis. The design of this study will allow distinction between pre-term birth (PTB) and growth retardation of the term infant (mature IUGR).

  • Perinatal Mortality [ Time Frame: after 20 weeks gestation up to 1 months of age ] [ Designated as safety issue: No ]
    The outcome is to determine, in poor food insecure communities if a daily comprehensive maternal nutrition supplement starting ≥ 3 months preconception and continuing throughout pregnancy will reduce the incidence of offspring perinatal mortality (including still births), compared with that for offspring of mothers who commence the same supplement starting at 12-16 weeks gestation.

  • Incidence of severe neonatal and infant infectious disease [ Time Frame: birth to 6 months of age ] [ Designated as safety issue: No ]
    Outcome measure is number of acute visits / admissions to health center/hospital for severe infectious disease. This secondary outcome will provide insight into the importance of maternal and fetal nutrition in the early prenatal development of host-defense mechanisms and, through comparison with the prenatal and control Arms, on the importance of maternal nutrition throughout pregnancy. It is further intended to collect minor morbidity data.

  • Epigenome (Maternal and Infant) [ Time Frame: baseline, 12 and 34 weeks gestation, delivery, and 3 months postpartum (maternal); 2 weeks and 3 months of age (infant) ] [ Designated as safety issue: No ]
    To compare longitudinal changes between groups in the maternal epigenome (including blood, buccal swabs, and possibly other readily obtainable samples) at baseline, 12 weeks pregnancy (prior to initiation of LNS in Arm 2), 34 weeks pregnancy, and at 3 months postpartum. Also will collect placental, fetal and cord blood epigenome at delivery by group and infant epigenome at 3 months with fingerstick blood and buccal swabs.

  • Deep phenotyping of maternal metabolic and nutritional status [ Time Frame: 12 and 34 weeks gestation, delivery and at 3 months postpartum ] [ Designated as safety issue: No ]
    The outcome represents deep phenotyping by measuring in maternal tissues: hormones, metabolites, measures of inflammation, oxidant stress and immune function/status, and nutrient biomarkers as possible indices of fundamental metabolic alterations resulting from improved long-term maternal nutrition in food insecure populations. Longitudinal blood samples will be collected from maternal participants in Arms 1 and 2 at baseline, 12 weeks gestation (prior to initiation of LNS in Arm 2), 34 weeks gestation, delivery and 3 months postpartum. Samples will also be collected from participants in Arm 3 at 34 weeks gestation and at 3 months postpartum.

  • Microbiome [ Time Frame: 12 & 34 weeks gestation and delivery (maternal); 14 days and 3 mo of age for the infant ] [ Designated as safety issue: No ]
    Based on potential long-term effects on maternal nutritional and metabolic state from preconception intervention, we hypothesize that the gut microbiota will differ between the two intervention arms at the three proposed time points.

  • Composition of breast milk [ Time Frame: 14 days postpartum ] [ Designated as safety issue: No ]
    We hypothesize that improved maternal nutrition at the time of greatest plasticity in early pregnancy will favorably influence maternal metabolic and nutritional status throughout pregnancy and thus potentially the composition of breast milk in terms of hormonal content, immune factors, cytokines, and gut growth factors.

Study Start Date: August 2013
Estimated Study Completion Date: October 2017
Estimated Primary Completion Date: October 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1: Preconception
Arm 1 will commence the comprehensive maternal nutrition intervention at 3-7 months postpartum. Delivery of the intervention will be monitored biweekly by collection of empty and unused sachets of the lipid-based supplement (LNS), maternal report, and casual observation of household behavior. Arm 1 participants will be weighed monthly and BMI calculated. If BMI <20 an additional energy supplement will be provided. Menstrual history will be obtained at each visit and a urine pregnancy test will be performed if menses is delayed.
Dietary Supplement: Comprehensive Maternal Nutrition Intervention
The nutrition intervention will be delivered before conception or at 12 weeks gestation and compared with a control group. The supplement to be used is a multi-micronutrient (MMN) fortified lipid-based supplement composed of dried skimmed milk, soybean and peanut extract, sugar, maltodextrin stabilizers, and emulsifiers.
Other Names:
  • multi micronutrient (MMN) fortified lipid-based supplement
  • lipid-based nutrient supplement
  • LNS
Experimental: Arm 2: Pregnancy
Participants in Arm 2 will commence the same comprehensive maternal nutrition intervention at 12 weeks gestation.
Dietary Supplement: Comprehensive Maternal Nutrition Intervention
The nutrition intervention will be delivered before conception or at 12 weeks gestation and compared with a control group. The supplement to be used is a multi-micronutrient (MMN) fortified lipid-based supplement composed of dried skimmed milk, soybean and peanut extract, sugar, maltodextrin stabilizers, and emulsifiers.
Other Names:
  • multi micronutrient (MMN) fortified lipid-based supplement
  • lipid-based nutrient supplement
  • LNS
No Intervention: Arm 3: Control
Participants in Arm 3 will receive biweekly visits to monitor pregnancy status. No health advice will be given other than information about prenatal care, location of delivery, and breastfeeding education in the third trimester.

Detailed Description:

The objective is to determine the benefits to the offspring of women in poor, food-insecure environments of commencing a daily comprehensive maternal nutrition supplement (with additional balanced calorie/protein supplement for underweight participants) ≥ 3 months prior to conception versus the benefits of commencing the same supplement at 12 weeks gestation and also to compare offspring outcomes with those of a control group which receives no supplement.
