Introduction: The Syrian conflict has displaced approximately 1.5 million people to Lebanon. In this setting of forced displacement, child marriage, insecurity, and limited access to sexual and reproductive health services can lead to increased rates of adolescent pregnancy, which have been linked to exacerbated maternal morbidity and mortality. Family planning can help to delay childbirth, increase time between pregnancies, and empower women to make their own reproductive health choices. To date, there is limited research on the knowledge of, and attitudes towards, family planning among Syrian refugees in Lebanon.Objective: Identify knowledge, attitudes, and perceptions towards family planning among Syrian refugees with the overarching goal of informing response strategies to improve sexual and reproductive health for displaced Syrian families in Lebanon.Methods: A thematic qualitative analysis of focus group discussions conducted in Lebanon in January 2017 by the ABAAD Resource Center for Gender Equality. The sample of 99 participants included Syrian women, girls and men.Results: While contraceptive use was generally deemed acceptable by women and girls, husbands’ and mother-inlaws’ attitudes towards fertility influenced their decisions about its use in practice. Additionally, reliable family planning services and sexual and reproductive health education were perceived as seldom available to Syrian refugees in Lebanon. Participants suggested that family planning awareness programs were needed for both parents and girls.Discussion: Changes at the policy, service, community, and individual levels are required to increase knowledge regarding and access to family planning services for Syrian refugees in Lebanon. In the interim, non governmental organizations may play a role in providing educational and supportive services for displaced Syrian girls and women.
