International audience. OBJECTIVE: The objective of this study was to investigate both the effects of low gestational age and infant's neurodevelopmental outcome at 2 years of age on the risk of parental separation within 7 years of giving birth. DESIGN: Prospective. SETTING: 24 maternity clinics in the Pays-de-la-Loire region. PARTICIPANTS: This study included 5732 infants delivered at <35 weeks of gestation born between 2005 and 2013 who were enrolled in the population-based Loire Infant Follow-up Team cohort and who had a neurodevelopmental evaluation at 2 years. This neurodevelopmental evaluation was based on a physical examination, a psychomotor evaluation and a parent-completed questionnaire. OUTCOME MEASURE: Risk of parental separation (parents living together or parents living separately). RESULTS: Ten percent (572/5732) of the parents reported having undergone separation during the follow-up period. A mediation analysis showed that low gestational age had no direct effect on the risk of parental separation. Moreover, a non-optimal neurodevelopment at 2 years was associated with an increased risk of parental separation corresponding to a HR=1.49(1.23 to 1.80). Finally, the increased risk of parental separation was aggravated by low socioeconomic conditions. CONCLUSIONS: The effect of low gestational age on the risk of parental separation was mediated by the infant's neurodevelopment.
