Methodology and indicators for NBCAL monitoring in stores and health services: a multicenter study (Multi-NBCAL).

The Brazilian Code of Marketing of Infant and Toddlers Food, Nipples, Pacifiers and Baby Bottles (NBCAL), in force in Brazil since 1988, is still systematically violated, exposing mothers and family members to illegal marketing of products that compete with breastfeeding. This study aimed to describe a multicenter study methodology and propose standardized indicators for NBCAL monitoring. This is a Multicenter Study for NBCAL Compliance Assessment (Multi-NBCAL) conducted in seven Brazilian cities: Rio de Janeiro, São Paulo, Ouro Preto (Minas Gerais State), Florianópolis (Santa Catarina State), Brasília (Federal District), João Pessoa (Paraíba State), and Belém (Pará State).
