Presentation at the A4NH Methods Gender-Nutrition Methods Workshop, December 6-7, 2013, Nairobi
Overview
• There are many research methods to use for linking gender, agriculture, and nutrition
• Need to remember the right tool for the right question, but most importantly, need to have an appropriate study design
• An ideal study design to understand gender, agriculture, health, nutrition linkages must be able to link and integrate: – Qualitative and quantitative methods– Social science and nutrition data
Why should the design take linkages into account from the start?
Qual and quant methods
• Demonstrated gains from various research programs from using mixed methods work (CPRC, CAPRi, IFPRI intrahousehold, GAAP, etc.)
• Quant work allows you to measure impacts, qual work enables you to understand why
• Both are important
Social science and nutrition
• Social norms underlying decisionmaking processes often determine the allocation of resources toward health and nutrition
• Among these are norms and practices surrounding gender
What to take into account in designing your studyQual and quant
• Integrated and iterative qual and quant
• Qual and quant researchers work together to define research questions, analyze and interpret results
• Qual study as diagnostic, help frame the questions
• Use quant sample to define “frame” of qual study—then can link qual study responses to quant data
• Quant sample typically uses larger n, qual study can use small to medium n, but be purposive
Social sciences and nutrition
• Have a “theory of behavior” that links behavior to nutrition outcomes
• Collect data on determinants (gender, resources, etc.) and on outcomes (nutrition, health, education, etc.)
• Collect data on the same individuals (same households) for whom you are collecting nutrition outcomes
Food-Based Approaches to Reducing Micronutrient Malnutrition
Intervention: Dissemination of improved agricultural technologies (vegetables and fish)
Nutrition Objective: Improve micronutrient status of producer population

Evaluating the long-term impact of agricultural technologies in Bangladesh
Panel data set based on 957 households surveyed in 1996/7 and 2006/7
3 technologies/implementation modalities:
1. improved vegetables for homestead production, disseminated through women’s groups (Saturia)
2. fishpond technology through women’s groups (Jessore)
3. fish pond technology targeted to individuals (Mymensingh)

Data collection efforts over the years• 1996-97: 4-round quantitative household survey
• Qualitative work on gender conducted between rounds 3 and 4 (Naved 2000)
• 2001: Qualitative work and further quantitative analysis to look at impact of new technologies on poverty, empowerment, vulnerability in 2000 (Hallman, Lewis, Begum 2007)
• 2006-2007: Qual-quant chronic poverty study– Focus groups (25% of sample villages)
– Quant household survey (all respondents and new households formed from original)
– Life histories (based on poverty transition category; poverty status computed from quant survey)
• 2010: Follow up on impacts of food price crisis
Information collected at household and individual levels in 1996-97 and 2006-7 rounds
Household
• Per capita expenditures (food, nonfood consumption)
• Household assets and landholdings
• Household income, by source
• Detailed production module
Individual
• HH roster information (age, sex, education, relationship to hh head)
• Schooling, labor and employment
• Land and assets
• Individual food consumption, 24-hour recall (and then converted to nutrient equivalents), all individuals
• Hemoglobin (via Hemocue), all children and women up to age 65
• Height, weight for all hh members

Note that dietary diversity modules were relatively “new” at the time of the baseline survey, but DD scores can be calculated from the food consumption module at household or Individual levels
