In The Lancet Global Health, Agrey H Mwakisole and colleagues explore the role of Christian religious leaders in promoting family planning in rural Tanzania. Given the roles that religious leaders can hold as trusted community messengers, the Article provides strong recommendations for including them in family planning initiatives, suggesting that, as an innovative and adaptable strategy, it could contribute positively to global initiatives towards universal access to modern contraception, if implemented broadly. The researchers also engaged equal numbers of male and female religious leaders, and data from this study suggest that the intervention increased women’s autonomy to choose to use contraception.
