Objective To determine whether a cash-for-work programme during the annual food insecurity period in Bangladesh improved nutritional status in poor rural women and children. Methods The panel study involved a random sample of 895 households from over 50 000 enrolled in a cash-for-work programme between September and December 2007 and 921 similar control households. The height, weight and mid-upper arm circumference of one woman and child aged less than 5 years from each household were measured at baseline and at the end of the study (mean time: 10 weeks). Women reported 7-day household food expenditure and consumption on both occasions. Changes in parameters were compared between the two groups. Findings At baseline, no significant difference existed between the groups. By the study end, the difference in mean mid-upper arm circumference between women in the intervention and control groups had widened by 2.29 mm and the difference in mean weight, by 0.88 kg. Among children, the difference in means between the two groups had also widened in favour of the intervention group for: height (0.08 cm; P < 0.05), weight (0.22 kg; P < 0.001), mid-upper arm circumference (1.41 mm; P < 0.001) and z-scores for height-for-age (0.02; P < 0.001), weight-for-age (0.17; P < 0.001), weight-for-height (0.23; P < 0.001) and mid-upper arm circumference (0.12; P < 0.001). Intervention households spent more on food and consumed more protein-rich food at the end of the study. Conclusion The cash-for-work programme led to greater household food expenditure and consumption and women's and children's nutritional status improved. [ABSTRACT FROM AUTHOR]

Objective: The current study assessed changes in children and mothers' nutritional status before and after raising Bangladeshi households out of extreme poverty through an income-generating activities (IGA) programme., Design: Extreme poor households took part in the IGA programme for 2 years and recruitment took place over four waves in annual cycles. Children and mothers were measured with regarding their nutritional status before and after the IGA programme commenced., Settings: Rural Bangladesh., Subjects: Three-hundred and eighty-two children under 5 years of age at recruitment, and their mothers., Results: After 2 years of the IGA programme, the prevalence of stunting significantly declined from 40·3 % to 33·0 % (P = 0·003), anaemia declined from 51·6 % to 44·0 % (P = 0·020) while mothers' CED (Chronic Energy Deficiency) declined from 52·0 % to 42·7 % (P < 0·001), but no significant changes were found in children's wasting, declining from 25·4 % to 21·5 %, underweight which remained the same at 43·2 %, while mothers' anaemia rose from 39·3 % to 42·7 %. There were also highly significant improvements in household socio-economic status. Increases in socio-economic security (especially in relation to cash savings and net income) and improvements in food quantity and quality (indicated by greater food diversity and animal food intake) were associated with normal nutritional status, and cessation of open defecation was associated with reduction in mothers' and child anaemia., Conclusion: The IGA programme was associated with increased household socio-economic security, such as asset accumulation, food security and sanitation, and with improvements in the nutritional status of children and their mothers in extreme poor households.

We assessed the relationship of fecal environmental contamination and environmental enteropathy. We compared markers of environmental enteropathy, parasite burden, and growth in 119 Bangladeshi children (≤ 48 months of age) across rural Bangladesh living in different levels of household environmental cleanliness defined by objective indicators of water quality and sanitary and hand-washing infrastructure. Adjusted for potential confounding characteristics, children from clean households had 0.54 SDs (95% confidence interval [CI] = 0.06, 1.01) higher height-for-age z scores (HAZs), 0.32 SDs (95% CI = -0.72, 0.08) lower lactulose:mannitol (L:M) ratios in urine, and 0.24 SDs (95% CI = -0.63, 0.16) lower immunoglobulin G endotoxin core antibody (IgG EndoCAb) titers than children from contaminated households. After adjusting for age and sex, a 1-unit increase in the ln L:M was associated with a 0.33 SDs decrease in HAZ (95% CI = -0.62, -0.05). These results are consistent with the hypothesis that environmental contamination causes growth faltering mediated through environmental enteropathy.

Objective: To determine how much of the variation in nutritional status of Bangladeshi children under 5 years old can be attributed to the socio-economic status of the family., Design: Nutritional status used reference Z-scores of weight-for-age (WAZ), height-for-age (HAZ) and weight-for-height (WHZ). A 'possession score' was generated based on ownership of a radio, television, bicycle, motorcycle and telephone, and the availability of electricity, with categories of 0 to 4+ possessions. A five-point (quintile) 'poverty index' was created using principal component analysis., Setting: The Bangladesh Demographic and Health Survey 2004 was the source of data., Subjects: A sample of 4891 children aged <5 years was obtained., Results: Some 57.8 % of the sample was either stunted, wasted or underweight (7.7 % were stunted, wasted and underweight). Of those stunted (48.4 %), 25.7 % were also underweight. Underweight and wasting prevalences were 40.7 % and 14.3 %, respectively. Mean WAZ, HAZ and WHZ did not differ by sex. Children of mothers with no education or no possessions were, on average, about 1 sd more underweight and stunted than those with higher educated mothers or with 4+ possessions. The possession score provided much greater discrimination of undernutrition than the poverty index. Nearly 50 % of children from households with no possessions were stunted, wasted or underweight (only 27 % in the poorest quintile), compared with only 3-6 % of children from households with 4+ possessions (over 13 % in the richest quintile)., Conclusions: Maternal education and possession score were the main predictors of a child's nutritional status. Possession score was a much better indicator of undernutrition than the poverty index.

A longitudinal study of 298 rural Bangladeshi infants found evidence of growth faltering starting at 3 months of age. Anthropometric status declined substantially in the first 2 years of life, with weight-for-height (WHZ) falling from - 0.49 to - 1.75, weight-for-age (WAZ) from - 1.18 to - 2.87 and height-for-age (HAZ) from - 1.00 to - 1.88. Higher concentrations of the acute-phase protein alpha-1-acid glycoprotein (AGP) and higher gut mucosal damage (as signified by raised lactulose:mannitol (L:M) ratios) were both associated with chronic malnutrition as indicated by poorer HAZ and WAZ scores (P = 0.011 and 0.005 for AGP and 0.039 and 0.019 for L:M ratio, respectively). Higher Hb levels were related to improved z-scores, while elevation of Giardia-specific IgM titre (GSIgM) was associated with poor WAZ and WHZ (P = 0.015 and 0.039, respectively). IgG did not show any significant association with z-scores and the L:M ratio did not correlate with any of the inflammation markers or Giardia infection. The prevalence of geohelminth infections was low (only 4 % in the total study period). However, the level of GSIgM indicated high endemicity of Giardia infection from early in life, although very few cysts were detected from stool samples. These findings suggest that rural Bangladeshi infants are being exposed to high levels of infection with concomitant gut damage and growth faltering.

In order to test the impact of Giardia and geohelminthic infection on infant growth faltering in Bangladesh, a randomised double-blind placebo controlled intervention of 36 weeks' duration was conducted in a rural community located 40 km northwest of Dhaka. Infants aged between 3 and 15 months were randomly assigned to either anti-Giardia and anthelminthic treatment, anti-Giardia treatment only, or a control. Weight and supine length were recorded every 4 weeks. Every 12 weeks intestinal permeability (lactulose/mannitol ratio), haemoglobin, plasma albumin, alpha-1-acid glycoprotein, IgG and Giardia-specific IgM (GSIgM) and eggs of the three common geohelminths and G. intestinalis cysts were determined. Data on 222 fully compliant infants were analysed. No significant differences in intestinal permeability, biochemical or anthropometric variables were found between the intervention groups, although there were associations between improvement in small intestinal mucosal function and better weight-for-age and weight-for-height (length) Z-scores. GSIgM titres indicated high endemicity with rapid re-infection of Giardia among infants; over 95% of infants were positive throughout the study, whereas the stool examination showed very few infants with either geohelminth eggs or Giardia cysts.
