RESUMO
Designing a cost-effective portfolio of micronutrient intervention programs is complex and generally undertaken with limited data. We developed the MINIMOD-Secondary Data (MINIMOD-SD) tool, which uses household consumption and expenditure survey data and other secondary data to estimate apparent nutrient intakes and model the effectiveness and cost-effectiveness of micronutrient intervention programs. We present the SD tool methodology and results in the context of Cameroon, with a particular focus on vitamin A (VA) for children and folate for women of reproductive age (WRA). We compared the MINIMOD-SD tool estimates with those of the full MINIMOD tool, which uses 24-h dietary recall data. The SD tool consistently underestimated folate intake among women (median (IQR): 230 (143,352) versus 303 (244,367) µg dietary folate equivalents (DFEs)/day) and especially VA among children (141 (64,279) versus 227 (102,369)). Qualitatively, however, the two tools were generally consistent in predicted subnational patterns of micronutrient adequacy and identification of effective and cost-effective (cost per child/WRA moving from inadequate to adequate intake) interventions. Secondary data and the MINIMOD-SD tool can provide policymakers with information to qualitatively assess deficiency risks and identify cost-effective interventions. However, accurately quantifying individual-level deficiency or dietary inadequacy and intervention effectiveness and cost-effectiveness will likely require individual-level dietary data and biomarker measurements.

Institutional delivery is an important factor associated with reduced maternal mortality rate (MMR). MMR in Haiti is high (350 per 100,000) and institutional delivery is low-just over 25 % of women delivered at a health facility in 2010. There also exists substantial rural-urban disparity in delivery with more hospital deliveries in urban than in rural areas. We aimed to study the prevalence and determinants of institutional delivery in a sample of women of childbearing age in rural Haiti. The study took place in Fond des Blancs and Villa, as part of a baseline assessment undertaken prior to implementation of a maternal, child health, nutrition, and water and sanitation program. From October to November 2011, women 15-49 years old (N = 575) were selected using a cross-sectional two-stage sampling strategy. We used descriptive and multivariate logistic regression analyses to assess the prevalence of and factors associated with institutional delivery. The prevalence of institutional delivery was 45.4 %; a rate higher than the national average of 25 %. In adjusted analyses, correlates of institutional delivery were younger maternal age (25 years and younger) (OR 1.82; CI 1.15, 2.90; P = 0.0112), antenatal care receipt (OR 3.70; CI 1.84, 7.43; P = 0.0003) and those who were poor according to our poverty index score classification (OR 2.04; CI 1.13, 3.69; P = 0.0187). This study shows that increased hospital delivery is likely explained by accessibility to antenatal care. Programs that improve access to antenatal care, with concurrent efforts to address structural inequalities that drive socio-economic deprivation, are likely critical to increasing institutional delivery.

Although recent immigrants to Canada are healthier than Canadian born (i.e., the Healthy Immigrant Effect), they experience a deterioration in their health status which is partly due to transitions in dietary habits. Since pathways to these transitions are under-documented, this scoping review aims to identify knowledge gaps and research priorities related to immigrant nutritional health. A total of 49 articles were retrieved and reviewed using electronic databases and a stakeholder consultation was undertaken to consolidate findings. Overall, research tends to confirm the Healthy Immigrant Effect and suggests that significant knowledge gaps in nutritional health persist, thereby creating a barrier to the advancement of health promotion and the achievement of maximum health equity. Five research priorities were identified including (1) risks and benefits associated with traditional/ethnic foods; (2) access and outreach to immigrants; (3) mechanisms and coping strategies for food security; (4) mechanisms of food choice in immigrant families; and (5) health promotion strategies that work for immigrant populations.
