RESUMEN

BACKGROUND: Bangladesh is urbanizing rapidly, facing challenges of malnutrition, low coverage and poor quality of urban nutrition services. OBJECTIVES: We assessed the effect of integrating maternal, infant, and young child nutrition interventions, delivered at urban Maternal Neonatal and Child Health facilities, on maternal dietary diversity, iron and folic acid (IFA) and calcium consumption, and child feeding practices. METHODS: We used a quasi-experimental design with a nonrandom assignment of 20 health care facilities in Dhaka to intensive and standard service arms. We conducted facility-based observations and community-based surveys at baseline (2020) and endline (2022) (n = 2455 observations and surveys with 1678 pregnant women [PW] or recently delivered women [RDW] at endline). We derived difference-in-difference (DID) estimates, adjusted for characteristics that differed at baseline or endline, and accounted for clustering. RESULTS: Exposure to antenatal care (ANC) was similar in both arms: two-thirds of RDW received ANC during the first trimester and three-fourths received ≥4 ANC checkups. Compared to the standard arm, a higher proportion of PW in the intensive arm received counseling on dietary diversity (DID: 45 percentage points [pp]), and a higher proportion of RDW received IFA (25 pp) and calcium supplementation (19 pp), showed adequate weight gain (44 pp), and recorded appropriate child feeding (27 pp). Improvements were greater in the intensive than the standard arm for the number of food groups consumed (DID: 1.1 food groups) and minimum dietary diversity (23 pp); no effect was observed for IFA and calcium consumption during pregnancy. However, effects were observed for early initiation of (20 pp) and exclusive breastfeeding (45 pp), introduction of solid or semisolid foods (28 pp), and egg and/or flesh food consumption (33 pp) among children. Minimum dietary diversity and acceptable diet remained low in both arms. CONCLUSIONS: Intensifying nutrition in government-aligned health care services delivered by experienced nongovernmental organization-run facilities is a feasible model to address the urban health gap, nutrition services coverage, and improve practices. The trial was registered at clinicaltrials.gov as NCT03882268.

RESUMEN

BACKGROUND: Public primary health facilities are an important source of nutrition services for the urban areas in Bangladesh. We aimed to understand the challenges and facilitators of delivering maternal and child nutrition services through public sector from the perspectives of the users and service providers. METHOD: The study was conducted in selected public primary health care facilities and their catchment area in Dhaka city from April-July 2019. We carried out 15 free listing exercises and 43 semi-structured interviews (SSI) with pregnant women and mothers of 0-24 months old children; 6 key informant interviews (KII) with facility managers and healthcare providers; and observed service delivery in 8 health facilities. RESULTS: Findings reveal that public primary health facilities address some economic and cultural barriers to access such as cost and provision of female service providers for maternal and child health services but challenges such as distance, waiting time, and cleanliness remained. In terms of service provision, there were gaps in provision of anthropometric measurement and counseling, and healthcare providers had inadequate training and therefore, knowledge of nutrition. The low priority given to nutrition services during program design hampered the delivery of nutrition services provided through urban public sector health facilities. CONCLUSIONS: There were important gaps in terms of service provision and capacity of healthcare providers, and therefore, the quality of nutrition service provided through public primary health care facilities. To maximize the coverage of quality nutrition services in the urban areas, it is important to think through the design of nutrition service delivery and allocate adequate resources to fill the material and capacity gaps.

RESUMEN

The International Code of Marketing of Breast-milk Substitutes (BMS) instituted to protect breastfeeding against unethical marketing, has been adopted by many countries, including Bangladesh. Despite national adoption, evidence suggests violations occur and inadequate BMS Code implementation is an issue. The study aimed to assess violations of the International BMS Code and the national 'Breast-milk Substitutes, Infant Foods, Commercially Manufactured Complementary Foods and the Accessories Thereof (Regulation of Marketing) Act, 2013' of Bangladesh in commercial settings (retail outlets and media) in Bangladesh, for different types of milk, bottles, and teats using a standardized Network for Global Monitoring and Support for Implementation of the Code and Subsequent relevant World Health Assembly Resolutions (NetCode) protocol. This cross-sectional quantitative study was conducted in Bangladesh from January to September 2018 in Dhaka, Chattogram, and Sylhet cities. Descriptive statistics were reported and χ2 tests were conducted to assess differences between categorical variables of interest. Data were analysed using SPSS version 20. In retail outlets, there were higher proportion of violations observed in Dhaka than in Sylhet and Chattogram (p < 0.001). Significantly greater proportion of violations in product labels occurred among products sold without local distributors compared to others (p < 0.05); violations were higher among "other milk" for children aged 0 to <36 months compared to formulas and growing-up milk (p < 0.05). Among media channels, internet clips had significantly higher proportions of violations compared to television, radio and newspaper (p < 0.001). BMS Code violations were prevalent in product labels and promotion of products through retail outlets. The study findings highlight the need for specific multisectoral strategies for better enforcement of BMS Code and points to the need for periodic assessment of Code violations.

RESUMEN

The National Nutrition Services of Bangladesh aims to deliver nutrition services through the primary health care system. Little is known about the feasibility of reshaping service delivery to close gaps in nutrition intervention coverage and utilization. We used a scenario-based feasibility testing approach to assess potential implementation improvements to strengthen service delivery. We conducted in-depth interviews with 31 service providers and 12 policymakers, and 5 focus group discussions with potential beneficiaries. We asked about the feasibility of four hypothetical scenarios for preventive and promotive nutrition service delivery: community-based events (CBE) for pregnant women, well-child services integrated into immunization contacts; CBE for well-children, and well-child visits at facilities. Opinions on service delivery platforms were mixed; some recommended new platforms, but others suggested strengthening existing delivery points. CBE for pregnant women was perceived as feasible, but workforce shortages emerged as a key barrier. Challenges such as equipment portability, upset children and a fast-moving service environment suggested low feasibility of integrating nutrition into outreach immunization contacts. In contrast, CBE and facility-based well-child visits emerged as feasible options, conditional on having the necessary workforce, structural readiness and budget support. On the demand side, enabling factors include using interpersonal communication and involving community leaders to increase awareness, organizing events at a convenient time and place for both providers and beneficiaries, and incentives for beneficiaries to encourage participation. In conclusion, integrating preventive and promotive nutrition services require addressing current challenges in the health system, including human resource and logistic gaps, and investing in creating demand for preventive services.

RESUMEN

The COVID-19 pandemic is expected to have profound effects on healthcare systems, but little evidence exists on service provision, utilisation, or adaptations. This study aimed to (1) examine the changes to health and nutrition service delivery and utilisation in urban Bangladesh during and after enforcement of COVID-19 restrictions and (2) identify adaptations and potential solutions to strengthen delivery and uptake. We conducted longitudinal surveys with health care providers (n = 45), pregnant women (n = 40), and mothers of children <2 years (n = 387) in February 2020 (in-person) and September 2020 (by phone). We used Wilcoxon matched-pairs signed-rank tests to compare the changes before and during the pandemic. Services delivery for women and children which require proximity were severely affected; weight and height measurements fell by 20-29 percentage points (pp) for pregnant women and 37-57 pp for children, and child immunisations fell by 38 pp. Declines in service utilisation were large, including drops in facility visitations (35 pp among pregnant women and 67 pp among mothers), health and nutrition counselling (up to 73 pp), child weight measurements (50 pp), and immunisations (61 pp). The primary method of adaptation was provision of services over phone (37% for antenatal care services, 44%-49% for counselling). Despite adaptations to service provision, continued availability of routine maternal and child health services did not translate into service utilisation. Further investments are needed to provide timely and accurate information on COVID-19 to the general public, improve COVID-19 training and provide incentives for health care providers and ensure availability of personal protective equipment for providers and beneficiaries.

RESUMEN

INTRODUCTION: Despite high prevalence of malnutrition little is known about the quality of nutrition services provided through urban health systems. This study aimed to fill in knowledge gaps on quality of nutrition service provision at public primary health care facilities in urban Dhaka. METHOD: This cross-sectional study was conducted from April-July 2019 in Dhaka City. Fifty-three health facilities were sampled following NetCode protocol. Quality of nutrition services was assessed in terms of structural readiness, process, and client satisfaction. Structural readiness included equipment, guidelines, and registers, and knowledge of health professionals (n = 130). For process, client provider interaction was observed (ANC: n = 159, Pediatric: n = 150). For outcome assessment, client's satisfaction with nutrition service provision was measured through interviews with pregnant women (n = 165) and caregivers of 0-24 month-old children (n = 162). Bivariate and multivariate analyses were conducted using SPSS. RESULTS: There were gaps in availability of equipment and guidelines in health facilities. Only 30% of healthcare providers received basic nutrition training. The mean knowledge score was 5.8 (range 0-10) among ANC providers and 7.8 for pediatric service providers. Process: Only 17.6% health facilities had dedicated space for counselling, 48.4% of pregnant women received four key nutrition services; 22.6% of children had adequate growth monitoring; and 38.7% of caregivers received counselling on exclusive breastfeeding. Outcome: The mean satisfaction with services was 4.3 for ANC and 4.0 for paediatric visits (range 1-5). Participants attending public facilities had significantly lower satisfaction compared to those attending private and NGO health facilities. CONCLUSION: There were gaps in facility readiness, and implementation of nutrition services. The clients were more satisfied with services at private facilities compared to public. The gaps in nutrition service delivery need to be adequately addressed to ensure promotion of good nutrition and early detection and management of malnutrition among pregnant women and children in urban Bangladesh.

RESUMEN

OBJECTIVE: To assess feeding practices of infants born to HIV-positive women in Dar es Salaam, Tanzania. These data then served as a proxy to evaluate the adequacy of current infant feeding counselling. DESIGN: A cross-sectional survey of infant feeding behaviours. SETTING: Four clinics in greater Dar es Salaam in early 2008. SUBJECTS: A total of 196 HIV-positive mothers of children aged 6-10 months recruited from HIV clinics. RESULTS: Initiation of breast-feeding was reported by 95·4 % of survey participants. In the entire sample, 80·1 %, 34·2 % and 13·3 % of women reported exclusive breast-feeding (EBF) up to 2, 4 and 6 months, respectively. Median duration of EBF among women who ever breast-fed was 3 (interquartile range (IQR): 2·1, 4·0) months. Most non-breast-milk foods fed to infants were low in nutrient density. Complete cessation of breast-feeding occurred within 14 d of the introduction of non-breast-milk foods among 138 of the 187 children (73·8 %) who had ever received any breast milk. Of the 187 infants in the study who ever received breast milk, 19·4 % received neither human milk nor any replacement milks for 1 week or more (median duration of no milk was 14 (IQR: 7, 152) d). CONCLUSIONS: Infant feeding practices among these HIV-positive mothers resulted in infants receiving far less breast milk and more mixed complementary feeds than recommended, thus placing them at greater risk of both malnutrition and HIV infection. An environment that better enables mothers to follow national guidelines is urgently needed. More intensive infant feeding counselling programmes would very likely increase rates of optimal infant feeding.

RESUMEN

BACKGROUND: Dietary supplements providing physiologic amounts of several micronutrients simultaneously have not been thoroughly tested for combating micronutrient deficiencies. OBJECTIVE: We determined whether a beverage fortified with 10 micronutrients at physiologic doses influenced the iron and vitamin A status and growth of rural children (aged 6-11 y) attending primary schools. DESIGN: In this randomized, double-blind, placebo-controlled efficacy trial, children were assigned to receive the fortified beverage or an unfortified beverage at school for 6 mo. RESULTS: There were nonsignificant differences at baseline between children in the fortified and nonfortified groups in iron status, serum retinol, and anthropometry. At the 6-mo follow-up, among children with anemia (hemoglobin < 110 g/L), there was a significantly larger increase in hemoglobin concentration in the fortified group than in the nonfortified group (9.2 and 0.2 g/L, respectively). Of those who were anemic at baseline, 69.4% in the nonfortified group and 55.1% in the fortified group remained anemic at follow-up (RR: 0.79), a cure rate of 21%. The prevalence of children with low serum retinol concentrations (< 200 microg/L) dropped significantly from 21.4% to 11.3% in the fortified group compared with a nonsignificant change (20.6% to 19.7%) in the nonfortified group. At follow-up, mean incremental changes in weight (1.79 compared with 1.24 kg), height (3.2 compared with 2.6 cm), and BMI (0.88 compared with 0.53) were significantly higher in the fortified group than in the nonfortified group. CONCLUSION: The fortified beverage significantly improved hematologic and anthropometric measurements and significantly lowered the overall prevalence of anemia and vitamin A deficiency.

RESUMEN

Anthropologic research was conducted among pregnant and lactating women in rural Tanzania in conjunction with clinical trials of a micronutrient-fortified beverage. Use of the beverage was examined through interviews and ethnographic observation in clinics and at home. Women liked the taste of the beverage, considered it beneficial to their health, preferred it to pills or injections, and most were willing and able to use it according to instructions. Most consumed the beverage according to schedule in the hope of improving pregnancy outcomes. However, public health facilities in Tanzania are not currently equipped to ensure regular delivery of micronutrient supplements, and many of the women with the worst nutrition profiles are also those who would be least able to purchase supplements on the open market. Successful distribution of micronutrient supplements in forms that appeal to consumers, such as a fortified beverage, will require programmatic attention to locally appropriate social marketing and to the challenges of reaching those with extremely low incomes.

RESUMEN

Traditionally, the main strategies used to control micronutrient deficiencies have been food diversification, consumption of medicinal supplements, and food fortification. In Tanzania, we conducted efficacy trials using a dietary supplement as a fourth approach. These were randomized, double-blind, placebo-controlled efficacy trials conducted separately first in children and later in pregnant women. The dietary supplement was a powder used to prepare an orange-flavored beverage. In the school trial, children consumed 25 g per school day attended. In the pregnancy trial, women consumed the contents of two 25-g sachets per day with meals. This dietary supplement, unlike most medicinal supplements, provided 11 micronutrients, including iron and vitamin A, in physiologic amounts. In both trials we compared changes in subjects consuming either the fortified or the nonfortified supplement. Measures of iron and vitamin A status were similar in the groups at the baseline examination, but significantly different at follow-up, always in favor of the fortified groups. Children receiving the fortified supplement had significantly improved anthropometric measures when compared with controls. At four weeks postpartum, the breast milk of a supplemented group of women had significantly higher mean retinol content than did the milk of mothers consuming the nonfortified supplement. The advantages of using a fortified dietary supplement, compared with other approaches, include its ability to control several micronutrient deficiencies simultaneously; the use of physiologic amounts of nutrients, rather than megadoses that require medical supervision; and the likelihood of better compliance than with the use of pills because subjects liked the beverage used in these trials.

RESUMEN

OBJECTIVE: Heat-treating expressed breastmilk is recommended as an interim feeding strategy for HIV-exposed infants in resource-poor countries, but data on its feasibility are minimal. Flash-heating (FH) is a simple in-home technique for heating breastmilk that inactivates HIV although preserving its nutritional and anti-infective properties. Our primary objective was to determine, among HIV-infected mothers, the feasibility and protocol adherence of FH expressed breastmilk after 6 months of exclusive breastfeeding. DESIGN: Prospective longitudinal. PARTICIPANTS: One hundred one HIV-infected breastfeeding mothers. SETTING: Dar es Salaam, Tanzania. INTERVENTION: Peer counselors provided in-home counseling and support on infant feeding from 2 to 9 months postpartum. Mothers were encouraged to exclusively breastfeed for 6 months followed by FH expressed breastmilk if her infant was HIV negative. Clinic-based staff measured infant growth and morbidity monthly, and mothers kept daily logs of infant morbidity. FH behavior was tracked until 9 months postpartum using daily logs, in-home observations, and clinic-based and home-based surveys. Bacterial cultures of unheated and heated milk samples were performed. RESULTS: Thirty-seven of 72 eligible mothers (51.4%) chose to flash-heat. Median (range) frequency of milk expression was 3 (1-6) times daily and duration of method use on-study was 9.7 (0.1-15.6) weeks. Mean (SD) daily milk volume was 322 (201) mL (range 25-1120). No heated and 32 (30.5%) unheated samples contained bacterial pathogens. CONCLUSIONS: FH is a simple technology that many HIV-positive women can successfully use after exclusive breastfeeding to continue to provide the benefits of breastmilk while avoiding maternal-to-child transmission associated with nonexclusive breastfeeding. Based on these feasibility data, a clinical trial of the effects of FH breastmilk on infant health outcomes is warranted.

RESUMEN

Maternal malnutrition continues to be a major contributor to adverse reproductive outcomes in developing countries, despite longstanding efforts to fortify foods or to distribute medicinal supplements to pregnant women. The objective of this study was to test the effect of a micronutrient-fortified beverage containing 11 micronutrients (iron, iodine, zinc, vitamin A, vitamin C, niacin, riboflavin, folate, vitamin B-12, vitamin B-6 and vitamin E) on the hemoglobin, iron and vitamin A status of pregnant women in Tanzania. A group of 259 pregnant women with gestational ages of 8 to 34 wk were enrolled in a randomized double-blind controlled trial in which study women received 8 wk of supplementation. Hemoglobin, ferritin and dried blood spot retinol were measured at baseline and at the end of the supplementation period. The supplement resulted in a 4.16 g/L increase in hemoglobin concentration and a 3 micro g/L increase in ferritin and reduced the risk of anemia and iron deficiency anemia by 51 and 56%, respectively. The risk of iron deficiency was reduced by 70% among those who had iron deficiency at baseline and by 92% among those who had adequate stores. The micronutrient-fortified beverage may be a useful and convenient preventative measure, one that could help improve the nutritional status of women both before and during pregnancy and thereby help avoid some of the potential maternal and fetal consequences of micronutrient deficiencies.

RESUMEN

Currently the three main widely used strategies to control micronutrient deficiencies are food diversification, fortification, and consumption of medicinal supplements. In Tanzania a fourth strategy has been evaluated in school children, and is to be studied in pregnant and lactating women. The dietary supplement comes in the form of a powder used to prepare a fruit flavored drink. Children consumed for six months 25 grams per school day attended, the powder being added to 200 ml of water. The dietary supplement provides between 40 and 100 percent of the RDA of 10 micronutrients, which includes iron, vitamin A and iodine. Unlike medicinal supplements it provides the multiple vitamins and minerals in physiologic, not megadoses. In a well conducted randomized double blind placebo controlled trial, a dietary supplement in the form of a fortified powder fruit drink produced statistically significant differences not only in vitamin A and iron status, but also in the growth of young school age children.
