Title: Preventing Linear Growth Faltering and Reversal of Stunting Among Low Birth Weight Infants in Bangladesh: a Community-based Cluster Randomized Control Trial
Brief Summary: Low birth weight (LBW) infants are particularly vulnerable to frequent infections and consequent morbidity resulting in sub-optimal breastfeeding, limited ingestion of complementary foods and ultimately micronutrient deficiencies that result in post-natal linear growth faltering. The objective of this study is to facilitate improved feeding practices through the early reduction of infections using the innovative tools of water-based hand sanitizer (beginning at birth) and an improved micronutrient powder (I-MNP) (beginning at 6 months of age). A community-based cluster randomized controlled trial will be carried out in Bangladesh using a 2x2 factorial design. LBW infants (n=480) will be recruited at birth and allocated to either HS or No HS from 0 to 6 months. From 6 to 12 months, half of the children in each group will be randomized to receive I-MNP. All groups will receive nutrition and hygiene education from birth to 12 months. Recumbent length is the primary outcome; morbidity, dietary intake and hemoglobin will be assessed as secondary outcomes. By working with BRAC, the largest implementation agency in Bangladesh, there is the opportunity to translate the results directly and quickly into child health programs in Bangladesh.


Options:
A: Inclusion Criteria:

* infants born as singletons and full term (mothers will be identified at \~8 months or \>37 weeks gestation to avoid including premature babies who are at high risk of neonatal mortality).
* must have a birth weight ≥1800g and \<2500g.
* Families involved in the study must be planning to remain in the study community for the next 12 months
* written consent must be received from an authorized guardian.
* all pregnant women will be identified and visited during their 8th month of pregnancy. A local informant will be identified for birth notification, who will inform the CHW (with a cell phone) when a child is born. All newborns will be screened and those who meet the inclusion criteria will be enrolled.

Exclusion Criteria:

* newborns with severe illnesses or congenital abnormalities /severe malformations that affect feeding will be excluded from the study.
* infants whose mothers did not survive during childbirth will be excluded.
B: Inclusion Criteria:

* Guatemala: pregnant mothers and subsequently their born children up to the age of 24 months;
* Burundi: cross-sectional study: children 0 to 42 of age.

Exclusion Criteria:

* none
C: Inclusion Criteria:

* Age 6-24 months
* Ingesting weaning food in addition to breastmilk
* Free from malaria or other major illnesses
* Afebrile
* Living in Brong Ahafo Region of Ghana for duration of intervention and follow-up

Exclusion Criteria:

* Severe anemia (hemoglobin \<70g/L)
* Weight-for-height \<-3 z-score(severe wasting)
* Kwashiorkor (defined as evidence of edema)
* Congenital abnormality
* Treatment with iron supplements within the past 6 months
* Presence of any chronic illness
D: Inclusion Criteria:

* Mother at least ≥15 years of age, infants 5.5- 6.5 months
* Willingness to provide informed consent
* Apparent good health
* Long-term residence in study site and anticipating residing in the area for at least 3 years
* Speak a Mjikenda language or Kiswahili in the home
* Willingness to provide blood samples during clinic visits

Exclusion Criteria:

* Hemoglobin \<70 g/L for infants; these infants will be referred for treatment at the local health clinic/hospital.
* Acute or chronic pulmonary, cardiovascular, hepatic, renal or neurological condition or any other finding that in the opinion of the PI or co-researchers that would increase risk of participating in the study.
* Other conditions that in the opinion of the PI or co-researchers would jeopardize the safety or rights of a participant in the trial or would render the participant unable to comply with the protocol
