In the Philippines, poor sexual and reproductive health (SRH) of women and girls is a grave public health challenge: one in five girls is a mother by age 19, two-thirds of women are not using any form of birth control, and more than a third of women’s pregnancies are unwanted. This study provides insights into the social norms and other factors that act as a barrier to the access and use of SRHR information and services by women and girls. Along with identifying the belief systems influencing women’s and girl’s access and use of SRHR information and services, the report also identifies key influencing factors (e.g. conflict, class, religion, education, technology), as well as positive outliers, key allies and positive influences as potential pathways to social norm change.
