Several behaviour-change communication (BCC) approaches have been effective in changing health-related behaviours, as well as increasing the demand for appropriate health services. However, limitations have been found in these approaches to varying degrees. As in the first part of this query (part one), results for this review are primarily taken from countries or regions with Islam as the dominant religion. Results from health- and nutrition-related projects using BCC are included for the following socially-conservative settings: Afghanistan, Benin, Bangladesh, Djibouti, Egypt, Ethiopia, Ghana, Indonesia, Iran, Kenya, Malaysia, Malawi, Niger, Nigeria, Pakistan, Philippines, Tanzania, Thailand, and Yemen. These groups therefore have more similar health behaviours and Islamic views on use of health services.
