Purpose

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

Intervention Model Description
This study uses a cluster-randomized controlled trial design to evaluate the effectiveness of different food voucher amounts and nutrition education interventions among low-income households in the Philippines. Study clusters are randomly assigned to one of four groups: monthly food vouchers valued at PhP 3,000, PhP 5,000, or PhP 8,000, or a control group receiving no voucher. Voucher interventions are combined with nutrition-focused social and behavior change communication (SBCC) sessions delivered by trained local government staff. Outcomes will be compared across study groups to assess the effects of the interventions on food security, dietary quality, nutrition knowledge, and nutritional status.

Arm Groups

ArmDescriptionAssigned Intervention
No Intervention
Control: No Voucher 		Households in this arm do not receive food vouchers during the study period
Experimental
Monthly Food Voucher - PhP 3,000 		Households 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.
  • Behavioral: Food Voucher + SBCC (PhP 3,000)
    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.
Experimental
Monthly Food Voucher - PhP 5,000 		Households 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.
  • Behavioral: Food Voucher + SBCC (PhP 5,000)
    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.
Experimental
Monthly Food Voucher - PhP 8,000 		Households 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.
  • Behavioral: Food Voucher + SBCC (PhP 8,000)
    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.

Detailed Description

The REVIVE study is a cluster-randomized controlled trial designed to evaluate the effectiveness of revised food voucher interventions combined with nutrition-focused Social and Behavior Change Communication (SBCC) among low-income households in the Philippines. The study will compare three monthly voucher amounts (PhP 3,000, PhP 5,000, and PhP 8,000) with a control group receiving no voucher to assess whether larger voucher values lead to greater improvements in food security, dietary quality, and nutrition-related outcomes. The intervention includes structured food vouchers with revised allocations emphasizing protein-rich foods, fruits, and vegetables, together with nutrition education sessions delivered by trained local government staff. The study will be implemented across selected urban and rural areas in the Philippines. Researchers will collect household- and individual-level data through surveys, dietary assessments, and anthropometric measurements to examine the effects of the intervention on household food consumption, nutrition knowledge, food insecurity, dietary quality, and nutritional status among women of reproductive age and children under five years of age. The study will also assess potential spillover effects within participating communities.
