This factsheet focuses on Young Women’s Support Groups (YSWGs) or safe spaces for girls. This is the seventh in a series of PRRINN-MNCH factsheets on the theme of Community Engagement which summarises that targeted strategies are required to improve maternal, newborn and child health among young married women in the north of Nigeria. Overall, Young Women’s Support Groups in PRRINN-MNCH communities had positive effects on health-seeking behaviour. The benefits of these groups extended beyond health. In conclusion, if the least-supported young women are to be reached, a strategy of ‘targeting within an age-specific target group’ is essential.
