Objective: Chronic undernutrition is a common phenomenon in Bangladesh. However, information is grossly lacking to report the correlation between chronic undernutrition trajectory and lung function in children. The aim of the current study was to understand the association between early-childhood chronic undernutrition trajectory and lung function at preadolescence., Design: The current study is a part of the 9-year follow-up of a large-scale cohort study called the Maternal and Infant Nutrition Interventions in Matlab., Settings: The current study was conducted in Matlab, a sub-district area of Bangladesh that is located 53 km south of the capital, Dhaka., Participants: A total of 517 children participated in lung function measured with a spirometer at the age of 9 years. Weight and height were measured at five intervals from birth till the age of 9 years., Results: Over half of the cohort have experienced a stunting undernutrition phenomenon up to 9 years of age. Children who were persistently or intermittently stunted showed lower forced expiratory volume (ml/s) than normal-stature children (P < 0·05). Children who exhibited catch-up growth throughout 4·5 years from the stunted group showed similar lung function with normal counterparts, and a better lung function than in children with the same growth velocity or who had faltering growth. In the multivariable models, similar associations were observed in children who experienced catch-up growth than their counterparts after adjusting for covariates., Conclusion: Our data suggest that catch-up growth in height during early childhood is associated with a better lung function at preadolescence.

Objective: To investigate the association between current childhood nutritional status and current wheezing among pre-school children in rural Bangladesh., Design: Cross-sectional study., Setting: Matlab region, rural Bangladesh., Subjects: Children (n 912) aged 4·5 years. Anthropometric measurements of the mothers and their children were taken during a 1-year period from December 2007 to November 2008. Current wheezing was identified using the International Study of Asthma and Allergies in Childhood questionnaire. Serum total IgE was measured by human IgE quantitative ELISA. IgE specific antibody to dust mites (Dermatophagoides pteronyssinus) was measured by the CAP-FEIA system (Phadia AB, Uppsala, Sweden)., Results: Wheezing at 4·5 years old was significantly associated with stunting (OR = 1·58; 95 % CI 1·13, 2·22) and underweight (OR = 1·39; 95 % CI 1·00, 1·94). The association with stunting remained significant after adjustment for sex, birth weight, birth length, gestational age at birth, mother's parity, maternal BMI, family history of asthma, socio-economic status, season of birth and intervention trial arm (OR = 1·74; 95 % CI 1·19, 2·56)., Conclusions: Stunting was a significant risk factor for wheezing among rural Bangladeshi children. Further studies will be required to confirm the relationship between nutritional status and allergic illnesses in developing countries.

Background: The interaction between hypophosphatemia (HP) and severe malnutrition has received little attention. This study investigated the prevalence, severity, and risk factors of HP among severely malnourished children with sepsis in Bangladesh., Methods: Children aged 6-59 months admitted with sepsis to Dhaka Hospital from April 2010 to December 2011 were enrolled in the study and divided into two groups: severe acute malnutrition (SAM) and non-SAM groups. Plasma phosphate and the related biochemical parameters were measured upon admission and on the second and fourth days for both groups and the 10th day or discharge day for the SAM group., Results: The prevalence of HP (plasma phosphate <3.7 mg/dL) was 72.9% and 62.5% (P = 0.26) for 48 SAM and for 56 non-SAM patients, respectively; that of moderate-severe HP (phosphate <2 mg/dL) was 25.0% and 19.6%, respectively (P = 0.51). The plasma phosphate level of 21 SAM patients was significantly lower on the second and fourth days than upon admission (P = 0.03, P = 0.01, respectively); it then recovered on the 10th day or discharge day. On multiple logistic regression analysis, plasma potassium <2.5 mmol/L upon admission was found to be a risk factor for moderate or severe HP (adjusted odds ratio, 7.21; 95% confidence interval: 1.88-27.7)., Conclusion: HP is common among children with sepsis. Potassium <2.5 mmol/L upon admission is considered a risk factor for moderate or severe HP in children with sepsis., (© 2012 The Authors. Pediatrics International © 2012 Japan Pediatric Society.)

Phosphorus is an essential substance in our body, and hypophosphataemia (HP) is well-described in rickets, refeeding syndrome, diabetic ketoacidosis (DKA), and in chronic alcohol-abuse. However, to our knowledge, HP among severely-malnourished children has not been studied in detail, and information on prevalence, severity, and treatment is scarce. Currently, there are only a few published case reports of HP. This case series describes three cases of HP that presented to Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b). Our first case required mechanical ventilation for respiratory distress associated with severe hypokalaemia (K 1.1 mmol/L) and moderate hypophosphataemia (P 2.1 mg/dL). The second case presented with severe sepsis which was associated with symptomatic hypocalcaemia (Ca 1.68 mmol/L), hypokalaemia (K 1.82 mmol/L), and severe hypophosphataemia (P 0.9 mg/dL). The third case presented with pneumonia and sepsis which were complicated by hypokalaemia (K 2.05 mmol/L) and severe hypophosphataemia (P 1.1 mg/dL). Marked lethargy and severe hypotonia were associated with HP in all of these cases. Manifestations of HP are diverse and can occur in association with other electrolyte imbalances, especially among malnourished children. Malnutrition, combined with sepsis, is one of the major killers of children younger than 5 years of age, and both malnutrition and sepsis can cause HP. It is concluded that the underlying causes of morbidity, including HP, should be actively sought and treated to reduce the mortality of children aged below five years.

Objective: The present analysis aimed to observe nutritional impacts among children <5 years of age by mother's engagement in paid employment.Design: Between 1996 and 2012, 21 443 children <5 years of age with diarrhoea attended the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), Dhaka Hospital. They were enrolled in the hospital-based Diarrhoeal Disease Surveillance System and their relevant information was extracted from the electronic database.Setting: The icddr,b, Bangladesh.Subjects: The analytic sample was 19 597 children aged <5 years who had a mother aged ≤35 years with or without engagement in paid employment.Results: Eleven per cent of the mothers (n 2051) were currently engaged in paid employment on behalf of the family. Univariate analysis showed that children with mothers engaged in paid employment had a 1·14 times higher risk of being undernourished, a 1·20 times of higher risk of being stunted, a 1·21 times higher risk of being wasted and a 1·31 times higher risk of being underweight (risk ratios) than were children with mothers not likewise engaged. Multivariate analysis showed that such associations remained significant for stunting (1·08; 95 % CI 1·00, 1·16), wasting (1·15; 95 % CI 1·06, 1·25) and underweight (1·09; 95 % CI 1·02, 1·17) after controlling for covariates.Conclusions: Mothers' engagement in income-generating employment was associated with undernutrition in children <5 years of age in urban Bangladesh.
