Interventions to prevent child marriage among young people in low- and middle-income countries: a systematic review of the published and gray literature

This review found that six high-quality and evaluated interventions reduced the proportion of married girls or delayed age at marriage in different contexts.

Most of these interventions provided cash transfers and/or support to reduce costs supported by families to educate girls. However, nearly all interventions only looked at whether girls remained unmarried at 18, and thus did not consider the possibility that they might get married as soon as they turn 18 or only a year later.

This review can help researchers, donors and policy makers reflect on which intervention might be appropriate to reduce child marriage in a given context, population or situation.
