Effects of third trimester counseling on pregnancy weight gain, birthweight, and breastfeeding among urban poor women in Bangladesh.

BACKGROUND: Maternal malnutrition and poor gestational weight gain are the most important causes of low birth weight and high rates of newborn mortality. OBJECTIVE: To assess the effects of nutrition counseling in the third trimester of pregnancy on maternal weight gain, birth weight of newborn, and breastfeeding practices. METHODS: This was a longitudinal experimental study with nutrition intervention for a period of 3 months. One hundred fifteen women (57 in the intervention group and 58 in the comparison group) who were visiting the Maternal and Child Health Training Institute at 6 months of pregnancy were randomly selected. The intervention group was given nutrition education twice in the first month and once a month for the next 2 months before delivery; the comparison group received routine hospital advice on food intake, immunization, personal hygiene, and breastfeeding. The women were weighed monthly up to delivery, the newborn infants' birth weights were measured within 24 hours after delivery, and breastfeeding practices were observed 1 month after delivery. RESULTS: Women in the intervention group gained 1.73 kg more weight during the third trimester than women in the comparison group (5.61 vs. 3.88 kg, p < 0.001). The mean birthweight of babies of women in the intervention group was 0.44 kg greater than that of babies of women in the comparison group (2.86 vs. 2.42 kg, p < 0.001). In the intervention group, 10.5% of babies were born with low birthweight, compared with 48.3% of the babies of women in the comparison group (p < 0.001). In the intervention group, 75.4% of mothers initiated breastfeeding within 1 hour after birth, compared with 34.5% of mothers in the comparison group (p < 0.001). CONCLUSIONS: Nutrition education only during the third trimester improved weight gain during pregnancy, reduced 78% of low birth weight, and improved breastfeeding practices.

Effect of nutrition education on exclusive breastfeeding for nutritional outcome of low birth weight babies.

BACKGROUND/OBJECTIVES: Low birth weight (LBW), defined as the body weight at birth of less than 2500 g, is a major public health problem in Bangladesh, where 37% of the babies are born with LBW. The objective of this study is to see the impact of nutrition education on growth of LBW babies with early initiation and exclusive breastfeeding compared to control group. SUBJECTS/METHODS: A total of 184 LBW babies and their mothers who attended the Maternal Care and Health Training Institute and Dhaka Medical College Hospital were randomly allocated to either intervention or control group. Enrollment of the study population started in May 2008 and was completed in October 2008. Nutrition education was given to mothers twice weekly for 2 months, on initiation of breastfeeding within 1 h, exclusive breastfeeding and increasing their dietary intake. Nutritional status of LBW babies was assessed for length and weight every 2 weeks. Data were analyzed using SPSS/Window's version 12. Comparison of mean of data was done using standard Student's t-test. RESULTS: Mean initial body weight and length of LBW babies were similar in both groups (2261±198 g vs 2241±244 g, P=0.535 and 43.0±1.3 cm vs 43.0±1.7 cm, P=0.77). Body weight and length of the LBW babies after 2 months increased significantly (3620±229 g vs 3315±301 g, P<0.001 and 50.2±1.3 cm vs 48.7±1.6 cm, P<0.001). It was found that the intervention group suffered less from respiratory illness compared with the control group (39% vs 66%, P<0.001). The rate of early initiation of breastfeeding was also significantly higher with nutrition intervention (59.8% vs 37.2%, P<0.001). Exclusive breastfeeding rate was significantly higher in intervention group (59.8% vs 37%, P=0.003). CONCLUSIONS: The present study showed that weight and length gain of LBW babies significantly increased by breastfeeding and nutrition education. Therefore, nutrition education on breastfeeding proves to be a strong tool to reduce the high risk of malnutrition and mortality of the LBW babies.

Zinc supplementation in the management of shigellosis in malnourished children in Bangladesh.

OBJECTIVE: To assess the impact of zinc supplementation on clinical recovery, weight gain and subsequent growth and morbidity in moderately malnourished children with shigellosis. DESIGN: A randomized, double-blind, controlled trial. SETTING: Dhaka hospital of ICDDR,B: Centre for Health and Population Research, Dhaka, Bangladesh. SUBJECTS: Fifty-six moderately malnourished children, aged 12-59 months with culture-proven shigellosis. METHODS: Subjects were randomly allocated to receive zinc (20 mg/day elemental) in multivitamin syrup (intervention) or multivitamin syrup without zinc (control) in two equally divided doses daily for 2 weeks. All children received pivmecillinam in a dose of 15 mg/kg every 6 h for 5 days. After supplementation, children were followed in their respective homes every 2 weeks for 6 months. RESULTS: Children receiving zinc recovered from acute illness significantly faster than the control children (P<0.05). The medians time (days) to recovery and disappearances of blood and mucous were significantly 50% shorter in the zinc-supplemented group compared to the control group. The mean body weight of zinc supplemented children increased significantly from 8.8 kg on admission to 9.2 kg (P<0.01) at recovery, which was not observed in the control children (from 9.3 to 9.6 kg; P=0.12). During the 6-month follow-up period, zinc-supplemented children had significantly fewer mean episodes of diarrhoea compared to the control children (2.2 vs 3.3; P=0.03). CONCLUSION: Zinc supplementation significantly shortens the duration of acute shigellosis, promotes better weight gain during recovery and reduces diarrhoeal morbidity during the subsequent 6 months.

Impact of zinc supplementation on subsequent morbidity and growth in Bangladeshi children with persistent diarrhoea.

This study was conducted to explore whether supplementation of zinc to children during persistent diarrhoea has any subsequent effect on morbidity and growth. A prospective follow-up study was conducted among children, aged 3-24 months, with persistent diarrhoea, who participated earlier in a double-blind randomized placebo-controlled trial. During persistent diarrhoea, children were randomly allocated to receive either zinc in multivitamin syrup or only multivitamin syrup for two weeks. After recovering from diarrhoea, 76 children in the multi-vitamin syrup and 78 children in the zinc plus multivitamin syrup group were followed up for subsequent morbidity and growth. Weekly morbidity and two-weekly anthropometric data were collected for the subsequent 12 weeks. Data showed that episodes and duration of diarrhoea were reduced by 38% and 44% respectively with supplementation of zinc. There was no significant difference in the incidence or duration of respiratory tract infection between the zinc-supplemented and the non-supplemented group. Improved linear growth was observed in underweight children (weight-for-age <70% of the National Center for Health Statistics standard) who received zinc compared to those who did not receive.
