Brief Summary
This study aims to evaluate whether revised food voucher programs, combined with nutrition education sessions, can improve food security, dietary quality, nutrition knowledge, and nutritional outcomes among low-income households in the Philippines. Researchers will compare different monthly voucher amounts-Philippine Peso (PhP) 3,000, PhP 5,000, and PhP 8,000-with a no-voucher control group to determine which approach is most effective. The main questions the study aims to answer are:
- Do food vouchers improve household food security, reduce hunger, and improve dietary quality and nutrient intake?
- Do larger voucher amounts lead to greater improvements in nutrition and health outcomes?
- Does enhanced nutrition education improve nutrition knowledge and healthy eating practices? Participants will:
- Receive either a monthly food voucher or no voucher, depending on study group assignment
- Attend nutrition education and Social and Behavior Change Communication (SBCC) sessions if assigned to a voucher group
- Complete household interviews on food consumption, household expenditures, food security, and nutrition knowledge
- Participate in dietary assessments and anthropometric measurements for women and children under 5 years of age

Outcome Measures
Primary Outcomes (5)
Nutrition Knowledge
Composite measure of nutrition knowledge assessed using a structured questionnaire administered to the primary household meal planner. The instrument includes items on food groups, dietary diversity, micronutrient-rich foods, maternal and child feeding practices, and understanding of voucher allocation rules. A total score will be constructed by summing correct responses and standardizing across respondents. Subdomain scores (e.g., dietary diversity knowledge, micronutrient knowledge, child feeding knowledge) will also be analyzed.
Baseline and End of intervention (approximately 24 months)
Individual Nutrient Adequacy
Summary measure of dietary nutrient adequacy among women of reproductive age and children under five years, derived from 24-hour dietary recall data. Probability of adequacy will be estimated for energy, macronutrients, and selected micronutrients (vitamin A, B-complex vitamins, vitamin C, calcium, iron, and zinc). The mean probability of adequacy will be calculated by averaging across 11 micronutrients.
End of intervention (approximately 24 months)
Minimum Dietary Diversity for Women (MDD-W)
Minimum Dietary Diversity for Women (MDD-W), defined as the proportion of women of reproductive age who consume foods from at least 5 of 10 food groups during the previous 24 hours, based on a 24-hour dietary recall.
End of intervention (approximately 24 months)
Global Dietary Quality Score (GDQS)
Global Dietary Quality Score (GDQS), a food-based metric derived from 24-hour dietary recall data that assesses overall dietary quality by accounting for consumption of both healthy and unhealthy food groups. GDQS ranges from 0 to 49, with higher scores indicating better dietary quality and lower risk of nutrient inadequacy and diet-related non-communicable diseases.
End of intervention (approximately 24 months)
Hunger and Food Insecurity Experience Scale
Household food insecurity and hunger will be assessed using the Food Insecurity Experience Scale (FIES), an experience-based measure consisting of eight questions about access to adequate food during the previous 4 weeks. The scale captures a range of food insecurity experiences, including worry about obtaining food, reduced dietary quality, reduced food quantity, skipping meals, and going without food. The raw FIES score ranges from 0 to 8, with higher scores indicating greater severity of food insecurity and hunger. Responses will be used to calculate both continuous FIES scores and categorical classifications of food insecurity severity.

Study Arms (4)
Control: No Voucher
NO INTERVENTIONHouseholds in this arm do not receive food vouchers during the study period
Monthly Food Voucher - PhP 3,000
EXPERIMENTALHouseholds receive a monthly food voucher valued at PhP 3,000, structured with a 10% allocation for carbohydrates and oils, 45% for protein-rich foods, and 45% for fruits and vegetables. Vouchers can be redeemed continuously and are accompanied by six structured nutrition-focused social and behavior change communication (SBCC) sessions delivered by trained local government staff.
Monthly Food Voucher - PhP 5,000
EXPERIMENTALHouseholds receive a monthly food voucher valued at PhP 5,000, with the same food group allocation (10% carbohydrates and oils, 45% protein, 45% fruits and vegetables) and continuous redemption design. Voucher receipt is combined with six SBCC sessions aimed at improving nutrition knowledge and dietary practices.
Monthly Food Voucher - PhP 8,000
EXPERIMENTALHouseholds receive a monthly food voucher valued at PhP 8,000, structured with 10% allocation for carbohydrates and oils, 45% for protein, and 45% for fruits and vegetables, and redeemed continuously. The intervention is paired with six nutrition-focused SBCC sessions delivered by trained local government personnel to improve dietary behaviors and nutrition knowledge.
Interventions
Households receive a monthly food voucher valued at PhP 3,000 with a structured allocation of 10% for carbohydrates and oils, 45% for protein-rich foods, and 45% for fruits and vegetables. Vouchers are redeemable continuously throughout the month. The intervention is combined with six structured social and behavior change communication (SBCC) sessions focused on nutrition knowledge, healthy dietary practices, maternal and child nutrition, and WASH behaviors, delivered by trained local government staff.
Households receive a monthly food voucher valued at PhP 5,000 with the same allocation structure (10% carbohydrates and oils, 45% protein, 45% fruits and vegetables) and continuous redemption design. The voucher is paired with six SBCC sessions covering nutrition education and behavior change topics related to diet quality and household nutrition.
Households receive a monthly food voucher valued at PhP 8,000 with the same structured food group allocation and continuous redemption system. The intervention includes six SBCC sessions aimed at improving nutrition knowledge and dietary practices for maternal and child health.
