Abstract: The formulation and communication of fish advisories are highly complex because of the potential conflict between the nutritional and toxicological issues associated with fish consumption. Government and organization-sponsored fish advisories have had limited success in changing behaviors. Participatory approaches may enhance the understanding of complex issues and the adoption of new behaviors. Here we used social network analysis to investigate the adoption of dietary changes within the context of a community participatory research project. In the Brazilian Amazon, many communities are highly exposed to methylmercury from fish consumption. A participatory intervention based on dietary changes aimed at reducing methylmercury exposure while maintaining fish consumption was initiated in 1995. In 2001, we collected data on individual participation in the research, on the discussion network regarding mercury issues and on changes in fish consumption from 96 of the 110 village households. More than half of men and women had adopted new fish consumption behavior to reduce mercury exposure. Adoption was associated with participation in the research project for both women and men, and with a higher number of discussion partners about mercury issues for women. Adoption was likewise associated with the presence of a female communication partner in the personal networks of both men and women. At the household level, men and women who considered their spouse as a discussion partner were more likely to adopt than those who did not. Opinion le]adership was associated with change in fish consumption only for women. We discuss the contribution of community participation and communication networks to overcome the difficulties in generating complex messages that take into account both health benefits and risks of fish consumption. We also discuss the relevance of building preventive health programs based on participatory research approaches and the roles and relations specific to men and women.
