Cost-effectiveness of universal iron supplementation and iron-containing micronutrient powders for anemia among young children in rural Bangladesh: analysis of a randomized, placebo-controlled trial.

BACKGROUND: Universal provision of iron supplements or iron-containing multiple micronutrient powders (MNPs) is widely used to prevent anemia in young children in low- and middle-income countries. The BRISC (Benefits and Risks of Iron Interventions in Children) trial compared iron supplements and MNPs with placebo in children <2 y old in rural Bangladesh. OBJECTIVES: We aimed to assess the cost-effectiveness of iron supplements or iron-containing MNPs among young children in rural Bangladesh. METHODS: We did a cost-effectiveness analysis of MNPs and iron supplements using the BRISC trial outcomes and resource use data, and programmatic data from the literature. Health care costs were assessed from a health system perspective. We calculated incremental cost-effectiveness ratios (ICERs) in terms of US$ per disability-adjusted life-year (DALY) averted. To explore uncertainty, we constructed cost-effectiveness acceptability curves using bootstrapped data over a range of cost-effectiveness thresholds. One- and 2-way sensitivity analyses tested the impact of varying key parameter values on our results. RESULTS: Provision of MNPs was estimated to avert 0.0031 (95% CI: 0.0022, 0.0041) DALYs/child, whereas iron supplements averted 0.0039 (95% CI: 0.0030, 0.0048) DALYs/child, over 1 y compared with no intervention. Incremental mean costs were $0.75 (95% CI: 0.73, 0.77) for MNPs compared with no intervention and $0.64 ($0.62, $0.67) for iron supplements compared with no intervention. Iron supplementation dominated MNPs because it was cheaper and averted more DALYs. Iron supplementation had an ICER of $1645 ($1333, $2153) per DALY averted compared with no intervention, and had a 0% probability of being the optimal strategy at cost-effectiveness thresholds of $200 (reflecting health opportunity costs in Bangladesh) and $985 [half of gross domestic product (GDP) per capita] per DALY averted. Scenario and sensitivity analyses supported the base case findings. CONCLUSIONS: These findings do not support universal iron supplementation or micronutrient powders as a cost-effective intervention for young children in rural Bangladesh.

Benefits and Risks of Iron Interventions in Infants in Rural Bangladesh.

BACKGROUND: Universal provision of iron supplements (drops or syrup) or multiple micronutrient powders to young children in low-to-middle-income countries where anemia is prevalent is recommended by the World Health Organization and widely implemented. The functional benefits and safety of these interventions are unclear. METHODS: We conducted a three-group, double-blind, double-dummy, individually randomized, placebo-controlled trial to assess the immediate and medium-term benefits and risks of 3 months of daily supplementation with iron syrup or iron-containing multiple micronutrient powders, as compared with placebo, in 8-month-old children in rural Bangladesh. The primary outcome was cognitive development, as assessed by the cognitive composite score on the Bayley Scales of Infant and Toddler Development, third edition, immediately after completion of the assigned 3-month regimen; scores range from 55 to 145, with higher scores indicating better cognitive performance. Secondary outcomes included the cognitive composite score at 9 months after completion of the assigned regimen; behavioral, language, and motor development, as well as growth and hematologic markers, immediately after completion and at 9 months after completion; and safety. RESULTS: We randomly assigned 3300 infants to receive iron syrup (1101 infants), multiple micronutrient powders (1099), or placebo (1100) daily. After completion of the assigned 3-month regimen, no apparent effect on the cognitive composite score was observed with iron syrup as compared with placebo (mean between-group difference in change in score from baseline, -0.30 points; 95% confidence interval [CI], -1.08 to 0.48) or with multiple micronutrient powders as compared with placebo (mean between-group difference in change in score from baseline, 0.23 points; 95% CI, -0.55 to 1.00). No apparent effect on any other developmental or growth outcome was observed immediately after completion of the assigned regimen or at 9 months after completion. At 9 months after completion of the assigned regimen, the prevalences of anemia, iron deficiency, and iron deficiency anemia increased in all three trial groups but remained lower among the children who received iron syrup or multiple micronutrient powders than among those who received placebo. The risk of serious adverse events and incidence of symptoms of infection were similar in the three trial groups. CONCLUSIONS: In this trial involving infants in Bangladesh, 3 months of daily supplementation with iron syrup or multiple micronutrient powders did not appear to have an effect on child development or other functional outcomes as compared with placebo.

Immediate impact of stay-at-home orders to control COVID-19 transmission on socioeconomic conditions, food insecurity, mental health, and intimate partner violence in Bangladeshi women and their families: an interrupted time series.

BACKGROUND: Stay-at-home orders (lockdowns) have been deployed globally to control COVID-19 transmission, and might impair economic conditions and mental health, and exacerbate risk of food insecurity and intimate partner violence. The effect of lockdowns in low-income and middle-income countries must be understood to ensure safe deployment of these interventions in less affluent settings. We aimed to determine the immediate impact of COVID-19 lockdown orders on women and their families in rural Bangladesh. METHODS: An interrupted time series was used to compare data collected from families in Rupganj upazila, rural Bangladesh (randomly selected from participants in a randomised controlled trial), on income, food security, and mental health a median of 1 year and 2 years before the COVID-19 pandemic to data collected during the lockdown. We also assessed women's experiences of intimate partner violence during the pandemic. RESULTS: Between May 19 and June 18, 2020, we randomly selected and invited the mothers of 3016 children to participate in the study, 2424 of whom provided consent. 2414 (99·9%, 95% CI 99·6-99·9) of 2417 mothers were aware of, and adhering to, the stay-at-home advice. 2321 (96·0%, 95·2-96·7) of 2417 mothers reported a reduction in paid work for the family. Median monthly family income fell from US$212 at baseline to $59 during lockdown, and the proportion of families earning less than $1·90 per day rose from five (0·2%, 0·0-0·5) of 2422 to 992 (47·3%, 45·2-49·5) of 2096 (p<0·0001 comparing baseline with lockdown period). Before the pandemic, 136 (5·6%, 4·7-6·6) of 2420 and 65 (2·7%, 2·1-3·4) of 2420 families experienced moderate and severe food insecurity, respectively. This increased to 881 (36·5%, 34·5-38·4) of 2417 and 371 (15·3%, 13·9-16·8) of 2417 during the lockdown; the number of families experiencing any level of food insecurity increased by 51·7% (48·1-55·4; p<0·0001). Mothers' depression and anxiety symptoms increased during the lockdown. Among women experiencing emotional or moderate physical violence, over half reported it had increased since the lockdown. INTERPRETATION: COVID-19 lockdowns present significant economic, psychosocial, and physical risks to the wellbeing of women and their families across economic strata in rural Bangladesh. Beyond supporting only the most socioeconomically deprived, support is needed for all affected families. FUNDING: National Health and Medical Research Council, Australia.

Prevalence of Maternal Postpartum Depression, Health-Seeking Behavior and Out of Pocket Payment for Physical Illness and Cost Coping Mechanism of the Poor Families in Bangladesh: A Rural Community-Based Study.

The burden of depression is high globally. Maternal depression affects the mother, the child, and other family members. We aimed to measure the prevalence of maternal postpartum depressive (PPD) symptoms having a child aged 6-16 months, health-seeking behavior for general illness of all family members, out of pocket (OOP) payments for health care and cost coping mechanisms. We conducted a cross sectional study with 591 poor families in rural Bangladesh. The survey was conducted between August and October, 2017. Information was collected on maternal depressive symptoms using the Self Reporting Questionnaire (SRQ-20), health-seeking behavior, and related costs using a structured, pretested questionnaire. The prevalence of depressive symptoms was 51.7%. Multiple logistic regression analysis showed that PPD symptoms were independently associated with maternal age (p = 0.044), family food insecurity (p < 0.001) and violence against women (p < 0.001). Most (60%) ill persons sought health care from informal health providers. Out of pocket (OOP) expenditure was significantly higher (p = 0.03) in the families of depressed mothers, who had to take loan or sell their valuables to cope with expenditures (p < 0.001). Our results suggest that postpartum depressive symptoms are prevalent in the poor rural mothers. Community-based interventions including prevention of violence and income generation activities for these economically disadvantaged mothers should be designed to address risk factors. Health financing options should also be explored for the mothers with depressive symptoms.

Self-reported health problems, health care seeking behaviour and cost coping mechanism of older people: Implication for primary health care delivery in rural Bangladesh.

BACKGROUND: Optimum utilization of primary health care system by older people is a challenge for every low and middle income country. Little is known about self reported health problems, health care seeking behaviour and cost coping mechanism of older people in developing countries. OBJECTIVES: This study aimed to measure self-reported health problems, health care seeking behaviour and expenditure coping mechanism of older people, and to describe its implication for primary health care delivery in rural Bangladesh. METHODOLOGY: It was a cross sectional study. In total, 362 older people were enrolled who sought health care preceding the last month of the interview. Descriptive and bivariate data analysis along with proportion test (z test) was carried out. RESULTS: The most frequent self-reported health problems were fever (43.8%) followed by physical pain (15.2%). More than half of the respondents (57.5%) had a second health problem. Only one third (33.8%) visited qualified health providers having minimum western health or medical training from government approved authority. More than half (54%) of the older people spent for health care out of pocket from their own. Only 2% older people sold their assets or took loans to meet their health care. 36% older people thought that they could afford to pay for health care in future. CONCLUSIONS: The findings of this study will help in developing primary health care policy for older people in rural Bangladesh and similar settings in South Asia.

Effects of adding psychosocial stimulation for children of lactating mothers using an unconditional cash transfer platform on neurocognitive behavior of children in rural Bangladesh: protocol for a cluster randomized controlled trial.

BACKGROUND: There is sufficient evidence that psychosocial stimulation (PS) benefits children's neurocognitive behavior, however, there is no information on how it works when delivered through an Unconditional Cash Transfer (UCT) platform for poor rural population in developing countries. The objective of this study is to measure effects of adding PS for children of lactating mothers enrolled to receive UCT with health education (HE) on neurocognitive behavior of children in rural Bangladesh. METHODS: The study will be conducted at 11 unions of Ullapara sub-district in Bangladesh. The study is a cluster randomized controlled trial with three-arms; (i) PS and UCT with HE (ii) UCT with HE and iii) Comparison arm. The cluster will be considered as an old Ward of a Union, the lowest tier of local government system in rural Bangladesh. There are three old Wards in a union. These three clusters will be randomized to one of the three arms. Similarly, randomization will be done for each 11 Unions and then 11 clusters will be assigned to an arm. Eighteen participants will be recruited from each cluster randomly (n = 196 in each arm). The intervention designed for one year includes UCT with HE for the poor as a safety net program in rural Bangladesh with or without PS. An age-based curriculum of PS is already available for Bangladeshi children and this will be administered by trained local women; play leaders (PL) in intervention clusters. The government of Bangladesh is providing UCT of taka 500 ($6.25) as maternity allowance per month with HE. The primary outcomes will be cognitive, motor and language composite scores measured by Bayley-III and behavior using Wolke's behavior rating scale. The secondary outcomes will be children and mothers' growth, family food security status, health seeking behavior, mothers' depressive symptoms and self-esteem and violence against mothers. DISCUSSION: The study will provide a unique opportunity to assess an integrated early childhood development intervention using UCT platform to mitigate developmental delays in poor vulnerable children of rural Bangladesh.
