Iron content of drinking water is associated with anaemia status among children in high groundwater iron areas in Bangladesh.

OBJECTIVE: Iron in groundwater provides a good source of absorbable iron for humans and can contribute to optimal iron and haemoglobin (Hb) status among populations. We aimed to examine the relationship between the iron content of groundwater and anaemia status among 12- to 23-month-old children in a rural area of Bangladesh. METHOD: A cross-sectional study was conducted in 80 randomly selected unions (the lowest administrative unit) in Sylhet and Moulvibazar districts of Bangladesh. A total of 800 children aged 12-23 months were selected via a systematic random sampling method. The child's age, sex, stunting status, consumption of iron-rich or iron-fortified food, maternal age and maternal body mass index (BMI) and the type of terrain were subjected to multiple logistic regression analysis to observe the independent relationships between groundwater iron content and anaemia in children. RESULTS: In total, 50.4% of children were anaemic. The odds of children being anaemic were 1.51-fold higher [OR: 1.51 (95% CI: 1.09, 2.09)] among households consuming water with an iron content <2 mg/L than in households consuming water with an iron content ≥2 mg/L. Childhood stunting, child's sex, child's age and the type of terrain were also significantly associated with anaemia among children. CONCLUSION: Groundwater with a high iron concentration was significantly associated with a decreased risk of childhood anaemia. This study provides evidence of the importance of groundwater iron to protect impoverished young children from anaemia.

Diarrhoeal disease knowledge among diarrhoea patient housholds: findings from the randomised controlled trial of the Cholera-Hospital-Based-Intervention-for-7-days (CHoBI7) mobile health program.

OBJECTIVE: The objective of this study was to evaluate the impact of the Cholera-Hospital-Based-Intervention-for-7-days (CHoBI7) handwashing with soap and water treatment mobile health (mHealth) program on diarrhoeal disease knowledge among diarrhoea patients and their household members in urban Dhaka, Bangladesh. METHODS: A cluster-randomised controlled trial of the CHoBI7 mHealth program was conducted among diarrhoea patient households in Dhaka, Bangladesh. Patients were randomised to three arms: standard recommendation on oral rehydration solution use; health facility delivery of CHoBI7 plus mHealth (weekly voice and text messages) (no home visits); and health facility delivery of CHoBI7 plus two home visits and mHealth. An open-ended questionnaire was administered to 1468 participants 12 years of age or older on diarrhoeal disease transmission and prevention. These items were combined to form a diarrhoeal disease knowledge score measured at baseline and at a 1 week, 6 month and 12 month follow-up. RESULTS: At baseline, when participants were asked to report three ways diarrhoeal diseases were spread 37% (546/1468) of participants reported by water, 13% (187/1468) by lack of handwashing and 4% (53/1468) by food not being covered properly. At baseline when asked to name three ways diarrhoeal diseases could be prevented, 35% (515/1468) of participants reported safe water, and 16% (228/1468) reported handwashing with soap. At the 12-month follow-up, the overall diarrhoeal disease knowledge score was significantly higher in the mHealth with no home visits arm (score coefficient: 0.69, 95% Confidence Interval: 0.36, 1.01, P < 0.0001) and the mHealth with two home visits arm (score coefficient: 1.18, 95% CI: 0.87, 1.49, P < 0.0001) compared with the standard recommendation arm. CONCLUSION: The CHoBI7 mHealth program significantly increased knowledge of diarrhoeal disease transmission and prevention among diarrhoea patients and their household members 12 months after in-person visits for program delivery were conducted.

OBJECTIF: L'objectif de cette étude était d'évaluer l'impact du programme CHoBI7 (Cholera-Hospital-Based-Intervention-for-7-days) de santé mobile (mHealth) sur la connaissance sur les maladies diarrhéiques chez les patients atteints de diarrhée et les membres de leur ménage dans la ville de Dhaka, au Bangladesh. MÉTHODES: Un essai contrôlé randomisé par grappes du programme mHealth CHoBI7 a été mené auprès de ménages de patients atteints de diarrhée à Dhaka, au Bangladesh. Les patients ont été randomisés dans trois groupes: recommandation standard sur l'utilisation de solutions de réhydratation orale; délivrance du programme CHoBI7 dans les services de santé plus mHealth (pas de visites à domicile); et délivrance du programme CHoBI7 dans les services de santé plus deux visites à domicile et mHealth. Un questionnaire ouvert a été administré à 1.468 participants âgés de 12 ans ou plus sur la transmission et la prévention des maladies diarrhéiques. Ces éléments ont été combinés pour former un score de connaissance sur les maladies diarrhéiques mesuré au départ et à 1 semaine, 6 mois et 12 mois. RÉSULTATS: Au départ, lorsqu'il a été demandé aux participants d'indiquer trois modes de propagation des maladies diarrhéiques, 37% (546/1468) des participants ont indiqué que ces maladies étaient transmises par l'eau, 13% (187/1468) par le manque de lavage des mains et 4% (53/1468) par le fait que les aliments n'étaient pas correctement couverts. Au départ, lorsqu'on leur a demandé de citer trois moyens de prévention des maladies diarrhéiques, 35% (515/1468) des participants ont cité l'accès à l'eau potable et 16% (228/1468) ont cité le lavage des mains avec du savon. Lors du suivi à 12 mois, le score global de connaissance sur la diarrhée était significativement plus élevé dans le bras mHealth sans visites à domicile (coefficient de score: 0,69, intervalle de confiance à 95%: 0,36-1,01; P < 0,0001) et le volet mHealth avec deux visites à domicile (coefficient de score: 1,18; IC 95%: 0,87-1,50; P < 0,0001) par rapport au bras de recommandation standard. CONCLUSION: Ces résultats suggèrent que le programme mHealth de CHoBI7 présente une approche prometteuse pour accroître les connaissances sur les maladies diarrhéiques dans les ménages de patients atteints de diarrhée.

Mothers' perception and healthcare seeking behavior of pneumonia children in rural bangladesh.

We describe mothers' perception about signs and symptoms, causes of the illness, and healthcare seeking behaviors related to pneumonia and express the major modifiable barriers to seeking timely treatment when their under-5 children had pneumonia in rural Bangladesh. Using focus group discussion, we understood mothers' perception and healthcare seeking behavior of childhood pneumonia. Although mothers described pneumonia as a serious life threatening disease in young children but most of the mothers (n = 24) could not diagnose whether their child had pneumonia or not. Environmental factors such as dust particles, spread from coughing mother, and drinking cold water or playing with water were perceived as the causes for pneumonia. Three common barriers noted were as follows: illness was not perceived as serious enough or distance from healthcare facility or lack of money at household for seeking treatment outside. Most of the rural mothers did not have knowledge about severity of childhood pneumonia.

Association between moderate-to-severe diarrhea in young children in the global enteric multicenter study (GEMS) and types of handwashing materials used by caretakers in Mirzapur, Bangladesh.

Handwashing practices among caretakers of case and control children < 5 years of age enrolled in the Global Enteric Multicenter Study in Mirzapur, Bangladesh were characterized and analyzed for association with moderate-to-severe diarrhea. Soap or detergent ownership was common, yet 48% of case and 47.7% of control caretakers also kept ashes for handwashing, including 36.8% of the wealthiest households. Soap, detergent, and ash were used for multiple hygiene purposes and were kept together at handwashing areas. Caretakers preferred soap for handwashing, but frequently relied on ash, or a detergent/ash mixture, as a low-cost alternative. Moderate-to-severe diarrhea was equally likely for children of caretakers who kept soap versus those who kept ash (matched OR = 0.91; 0.62-1.32). Contact with ash and water reduced concentrations of bacterial enteropathogens, without mechanical scrubbing. Thus, washing hands with ash is a prevalent behavior in Mirzapur and may help diminish transmission of diarrheal pathogens to children.
