BackgroundPerinatal psychological distress adversely impacts the well-being and social adjustment of parents and their children. Expectant parents who have migrated may be at higher risk for perinatal psychological distress due to various migration-specific stressors and healthcare service barriers. Limited studies have examined the perceived determinants of perinatal distress in immigrant parents, particularly men. This study explored first and second-generation immigrant parents’ lived experiences of social stressors and facilitators of perinatal psychological well-being.MethodsParticipants were recruited by convenience and purposive sampling as part of a larger study. Semi-structured interviews were conducted virtually with first and second-generation immigrant women and men in Quebec, Canada. An inductive thematic analysis was performed.ResultsSixteen women (age = 34.8 ± 3.7 years) and ten men (age = 35.1 ± 4.9 years) from various ethnic backgrounds participated in the study at 7.4 ± 0.73 and 7.5 ± 0.72 months postpartum, respectively. Three themes were identified: (1) cultural pressures (cultural differences in parenting, gender-related cultural pressures, health and baby-related practices), (2) health and social service access (social benefits and resources, and systemic barriers in health care), and (3) discrimination (physical appearance or parental-related discrimination, gender-related discrimination, ethnic-related discrimination). First-generation immigrant parents reported greater acculturative stress (i.e. mental health stigma, health care access) and ethnic discrimination concerns related to their distress. Among men, barriers include feeling as though the paternal role was devalued by society and not receiving consideration by health care.ConclusionsOur results highlight different social factors of perinatal well-being perceived by men and women from various ethnic and immigration backgrounds during the perinatal period. Perceived factors include macro-level factors, such as a country’s social climate, health and social policies and services, and social aspects of acculturative stress. Our findings suggest the need for continued efforts to challenge and eliminate discriminatory practices. Interventions and resources directed at first-generation immigrant parents should be bolstered. Understanding what parents perceive to facilitate or hinder their psychological well-being can help inform the development of tailored evidence-based programs and policies to better meet the mental health needs of Canadians and reduce gender disparities in the treatment of perinatal distress.
