Impact of market-based home fortification with micronutrient powder on childhood anemia in Bangladesh: a modified stepped wedge design.

Background: Anemia poses a significant public health problem, affecting 1.6 billion people and contributing to the loss of 68.4 million disability-adjusted life years. We assessed the impact of a market-based home fortification program with micronutrient powder (MNP) called Pushtikona-5 implemented by Bangladesh Rural Advancement Committee (BRAC) on the prevalence of anemia among children aged 6-59 months in Bangladesh. Methods: We used a modified stepped wedged design and conducted three baseline, two midline, and three endline surveys to evaluate the Pushtikona-5 program implemented through three BRAC program platforms. We interviewed children's caregivers, and collected finger-prick blood samples from children to measure hemoglobin concentration. We also collected data on coverage of Pushtikona-5 and infant and young child feeding (IYCF) practices. We performed bivariate and multivariable analysis and calculated adjusted risk ratios (ARRs) to assess the effect of program outcomes. Results: A total of 16,936 households were surveyed. The prevalence of anemia was 46.6% at baseline, dropping to 32.1% at midline and 31.2% at endline. These represented adjusted relative reductions of 34% at midline (RR 0.66, 95%CI 0.62 to 0.71, value of p <0.001) and 32% at endline (RR 0.68, 95%CI 0.64 to 0.71, value of p <0.001) relative to baseline. Regarding MNP coverage, at baseline, 43.5% of caregivers surveyed had heard about MNP; 24.3% of children had ever consumed food with MNP, and only 1.8% had consumed three or more sachets in the 7 days preceding the survey. These increased to 63.0, 36.9, and 4.6%, respectively, at midline and 90.6, 68.9, and 11.5%, respectively, at endline. Conclusion: These results show evidence of a reduction in the prevalence of anemia and an improvement in coverage. This study provides important evidence of the feasibility and potential for impact of linking market-based MNP distribution with IYCF promotion through community level health workers.

Use of concurrent evaluation to improve implementation of a home fortification programme in Bangladesh: a methodological innovation.

OBJECTIVE: This paper focuses on the use of 'concurrent evaluation' to evaluate a nationally scaled-up programme in Bangladesh that was implemented by BRAC (an international development organisation) using Shasthya Shebika (SS) - volunteer community health workers - to promote home fortification with micronutrient powders (MNP) for children under-five. DESIGN: We developed a programme impact pathway to conceptualise the implementation and evaluation strategy and developed a strategic partnership among the key programme stakeholders for better use of evaluation evidence. We developed a multi-method concurrent evaluation strategy to provide insights into the BRAC programme and created provision for course correction to the implementation plan while it was in operation. SETTING: One hundred sixty-four sub-districts and six urban slums in Bangladesh. PARTICIPANTS: Caregivers of children 6-59 months, SS and BRAC's staff members. RESULTS: The evaluation identified low awareness about home fortification among caregivers, inadequate supply and frequent MNP stockouts, and inadequate skills of BRAC's SS to promote MNP at the community level as hindrances to the achievement of programme goals. The partners regularly discussed evaluation results during and after implementation activities to assess progress in programme coverage and any needs for modification. BRAC initiated a series of corrections to the original implementation plan to address these challenges, which improved the design of the MNP programme; this resulted in enhanced programme outcomes. CONCLUSIONS: Concurrent evaluation is an innovative approach to evaluate complex real-world programmes. Here it was utilised in implementing a large-scale nutrition programme to measure implementation process and effectiveness.

LiST modelling with monitoring data to estimate impact on child mortality of an ORS and zinc programme with public sector providers in Bihar, India.

BACKGROUND: Many interventions have attempted to increase vulnerable and remote populations' access to ORS and zinc to reduce child mortality from diarrhoea. However, the impact of these interventions is difficult to measure. From 2010 to 15, Micronutrient Initiative (MI), worked with the public sector in Bihar, India to enable community health workers to treat and report uncomplicated child diarrhoea with ORS and zinc. We describe how we estimated programme's impact on child mortality with Lives Saved Tool (LiST) modelling and data from MI's management information system (MIS). This study demonstrates that using LiST modelling and MIS data are viable options for evaluating programmes to reduce child mortality. METHODS: We used MI's programme monitoring data to estimate coverage rates and LiST modelling software to estimate programme impact on child mortality. Four scenarios estimated the effects of different rates of programme scale-up and programme coverage on estimated child mortality by measuring children's lives saved. RESULTS: The programme saved an estimated 806-975 children under-5 who had diarrhoea during five-year project phase. Increasing ORS and zinc coverage rates to 19.8% & 18.3% respectively under public sector coverage with effective treatment would have increased the programme's impact on child mortality and could have achieved the project goal of saving 4200 children's lives during the five-year programme. CONCLUSIONS: Programme monitoring data can be used with LiST modelling software to estimate coverage rates and programme impact on child mortality. This modelling approach may cost less and yield estimates sooner than directly measuring programme impact with population-based surveys. However, users must be cautious about relying on modelled estimates of impact and ensure that the programme monitoring data used is complete and precise about the programme aspects that are modelled. Otherwise, LiST may mis-estimate impact on child mortality. Further, LiST software may require modifications to its built-in assumptions to capture programmatic inputs. LiST assumes that mortality rates and cause of death structure change only in response to changes in programme coverage. In Bihar, overall child mortality has decreased and diarrhoea seems to be less lethal than previously, but at present LiST does not adjust its estimates for these sorts of changes.

Factors Influencing Child Feeding Practices Related to Home Fortification With Micronutrient Powder Among Caregivers of Under-5 Children in Bangladesh.

BACKGROUND: Anemia is a major public health concern in Bangladesh, affecting about 51% of under-5 children. There are a number of strategies to overcome this micronutrient-deficiency burden, and home fortification (HF) with micronutrient powder (MNP) is one of them. OBJECTIVE: As part of an evaluation of an HF with MNP intervention program, we conducted a qualitative study to understand the factors influencing demand, purchase, and utilization of MNP by caregivers of under-5 children. METHODS: We purposively selected study participants from 5 subdistricts and 1 urban slum in Bangladesh where HF with Pushtikona (a brand name of MNP) program is available. Data were collected through household observations and conducting in-depth interviews and focus group discussions with caregivers, grandmothers, and fathers of under-5 children. RESULTS: Our study showed that caregivers were initially cautious, using Pushtikona on a trial basis, and afterward they employed various strategies to get their children to eat food fortified with Pushtikona. Barriers to acceptance and use of Pushtikona included inappropriate initiation of complementary feeding, discouragement from influential family members as well as miscommunication, conflicting information, and irregular visits by the health workers who sell Pushtikona to caregivers. Based on these findings, we characterized the users of Pushtikona as regular, ever, irregular, and never. CONCLUSION: The evidence suggests that focusing on counseling caregivers and other family members on the importance of MNP and on age-appropriate feeding practices will be critical to the success of this intervention program as will regular visits by health workers and improved service delivery.

Regarding realities: Using photo-based projective techniques to elicit normative and alternative discourses on gender, relationships, and sexuality in Mozambique.

This paper argues for the methodological merit of photo-based projective techniques (PT) in formative HIV communication research. We used this technique in Mozambique to study multiple sexual partnerships (MSPs) and the roles of social and gender norms in promoting or discouraging these behaviours. Facilitators used ambiguous photographs and vignettes to ease adult men and women into discussions of sexual risk behaviour and HIV transmission. Visuals upheld a third-person perspective in discussions, enabling participants to safely project their worldviews onto the photographed characters, and indirectly share their attitudes, normative environments, personal and peer experiences, perceived risks and benefits, and theories about motivations for extramarital sex. Visually grounded storylines contained rich detail about the circumstances and interpersonal conversations that contextualise MSP behaviour and norms. The research yielded findings about conflicting social practices of public encouragement and private disapproval. Despite concerns around the verifiability of PTs, the repetition and convergence in the elicited conversations - and confirmation through subsequent campaign design and evaluation - suggest these techniques can reliably elicit information for formative public health and communication research on psychosocial and normative factors.

Descriptive norms and male youth smoking in rural Minya, Egypt: a multilevel analysis of household and neighborhood normative influences.

INTRODUCTION: Research links normative influence to youth smoking in Egypt. This analysis assesses the association of descriptive norms at the household and neighborhood levels with the smoking behavior of 1,366 men aged 15-24 in rural Minya governorate, Egypt. METHODS: Data come from the 2004 Minya Village Health Survey of 6,096 people from 2,093 households. A two-level, random effects multivariate logistic regression model with individual data clustered at the neighborhood level was fit to the data. The strengths of normative influence at the household and neighborhood levels on male youths' smoking behavior were assessed, controlling for age, education, employment, outcome beliefs about smoking, and household wealth. RESULTS: Male youths who lived in a household with an adult male who smoked were much more likely to smoke than were youth who lived in a household with adult male(s) who did not smoke (odds ratio [OR] = 2.73, 95% CI = 1.84-4.07, p < .001). Living with one or more male youth who smoked was also strongly associated with male youth smoking (OR = 1.91, 95% CI = 1.29-2.84, p = .001). Living in a neighborhood with an SD greater than the population mean proportion of males who smoked (both adult and youth) was associated with a 24% greater likelihood of youth smoking (OR = 1.24, 95% CI = 1.04-1.48, p = .017). Unmeasured factors at the neighborhood level accounted for 3.1% of the variability. CONCLUSIONS: Young men in Minya who live with smokers or in neighborhoods with smokers are more likely to smoke. Policies and interventions enacted at the household and neighborhood levels may prevent youth smoking.

Normative influence and desired family size among young people in rural Egypt.

Research has identified the lack of acceptance of a two-child-family norm as the biggest obstacle to achieving replacement-level fertility in Egypt. This analysis examines norms about desired family size for 1,366 males and 1,367 females aged 15-24 in 2004 in rural Minya governorate. Two-level random-effects multivariate logistic regression models, stratified by sex and grouped by neighborhood, are used to assess normative influence at the household and neighborhood levels, controlling for individual- and household-level covariates. In the final model, young males in neighborhoods where more people desire a small family are 33 percent more likely to desire a small family than are young males in other neighborhoods. Young females in households with one or more adults preferring a small family are 78 percent more likely to desire a small family, and young females in households with one or more young people who prefer a small family are 37 percent more likely to desire a small family themselves, compared with those living with adults or with young people, respectively, who do not prefer a small family. Programs aiming to reduce fertility should be aware of gender differences in the sources of normative influence on desired family size.
