Nutritional insults and conditions in fetal life and infancy may influence later growth and body composition as well as the development of chronic diseases in adult life. We studied the effects of maternal food and micronutrient supplementation and exclusive breast-feeding counseling on offspring growth 0-54 months and body composition at 54 months of age. We also validated and developed equations for a leg-to-leg bioimpedance analyzer in order to assess body composition of Bangladeshi children aged 4-10 years. In the MINIMat trial in Matlab, Bangladesh, pregnant women were randomized to Early (around 9 weeks) or a Usual invitation (around 20 weeks) to food supplementation and to one of three daily micronutrient supplementations with capsules of either 30 mg Fe and 400 µg folic acid, or 60 mg Fe and 400 µg folic acid, or multiple micronutrient supplements (MMS) (15 micronutrients including 30 mg Fe and 400 µg folic acid). They were also randomized to exclusive breastfeeding counseling (EBC) or to usual health messages (UHM). Growth of their children was measured from birth to 54 months, when body composition also was assessed. There were no differences in background characteristics across the different intervention groups. There was no differential effect by prenatal interventions on birth weight or length. Early invitation to food supplementation reduced stunting from early infancy up to 54 months for boys (average difference 6.5 percent units, 95% CI=1.7 to 11.3, p=0.01), but not for girls (average difference 2.4 percent units, 95% CI=-2.2 to 7.0, p=0.31). MMS resulted in more stunting than standard Fe60F (average difference 4.8 percent units, 95% CI=0.8 to 8.9, p=0.02). Breast-feeding counseling prolonged the duration of exclusive breastfeeding (difference 35.0 days, 95% CI 30.6-39.5, p<0.001). Neither the pregnancy interventions nor the breast-feeding counseling influenced body composition at 54 months. Early food supplementation in pregnancy reduced the occurrence of stunting in boys 0-54 months, while prenatal MMS increased the proportion of stunting. Early food and multiple micronutrient supplementation or exclusive breastfeeding intervention provided to rural Bangladeshi women during pregnancy did not affect offspring body composition at 54 months of age. The effects on postnatal growth suggest programming effects in early fetal life.

To determine the relationship between infant-feeding practices and diarrhoeal infections, a descriptive survey was conducted to infants between six to 12 months of age. A guided interview was conducted to 105 mothers of infants who attended the health facilities of Mbabane, Swaziland. The results show that breast-feeding is routinely practiced by the majority of mothers and exclusive breast-feeding is very low, but supplementary feed in the form of formula or solids are introduced by the majority of respondents within the first three months of life. Infants who were given colostrum and breast milk had fewer diarrhoeal attacks. Other factors, for example education and cultural factors influenced the feeding practices and number of diarrhoeal attacks. It is recommended that breast-feeding should be promoted as an important intervention in the control of diarrhoea / Health Studies / M.A. (Nursing Science)

Anemia and micronutrient deficiencies in infancy are common in low-income settings. These are partly due to maternal malnutrition and may impair child health and development. We studied the impact of maternal food and micronutrient supplementation, duration of exclusive breastfeeding (EBF), growth and infection on infant anemia and micronutrient status. In the MINIMat trial in Matlab, Bangladesh, pregnant women were randomized to Early or Usual promotion of enrolment in a food supplementation program and to one of three daily micronutrient supplements. Capsules containing 400µg folic acid and (a) 30 mg iron (Fe30Fol), (b) 60 mg iron (Fe60Fol), (c) 30 mg iron and other micronutrients (MMS) were provided from week 14 of gestation. Capsule intake was assessed with the eDEM device recording supplement container openings. Blood samples (n=2377) from women at week 14 and 30 were analyzed for hemoglobin (Hb). Duration of EBF and infant morbidity was based on monthly maternal recalls. Infants were weighed and measured monthly. Blood samples (n=1066) from 6-months-old infants were analyzed for Hb and plasma ferritin, zinc, retinol, vitamin B12 and folate. In women, Hb increase per capsule reached a plateau at 60 Fe60Fol capsules, indicating that nine weeks of daily supplementation produced maximum Hb response. Anemia was common (36%) at capsule intakes >60 indicating other causes of anemia than iron deficiency. In infants, vitamin B12 deficiency prevalence was lower in the MMS (26.1%) than in the Fe30Fol group (36.5%), (p=0.003) and zinc deficiency prevalence was lower in the Usual than in the Early group. There were no other differential effects of food or micronutrient supplementation on infant anemia or micronutrient status. Infants exclusively breast-fed for 4-6 months had a higher mean plasma zinc concentration (9.9±2.3 µmol/L) than infants exclusively breast-fed for <4 months (9.5±2.0 µmol/L), (p< 0.01). No other differences in anemia, iron or zinc status were observed between EBF categories. Infection, low birth weight and iron deficiency were independent risk factors for infant anemia. Regardless of studied interventions, prevalence of anemia (43%), deficiency of zinc (56%), vitamin B12, vitamin A (19%) and iron (22%) in infancy was high and further preventive strategies are needed. / MINIMat
