First Heroes: Engaging Fathers in the First 1000 Days (First Heroes)

April 17, 2026 updated by: Elsie Taveras, MD, Massachusetts General Hospital

The First Heroes study plans to influence weight and health trajectories, modify disease risk, and improve health care services for mother-father-infant triads from racial/ethnic minority and health disparity populations.

This study is a two-arm, randomized controlled trial recruiting from Massachusetts General Hospital (MGH) obstetrics practices. This study will enroll 250 father-mother dyads in the second trimester of pregnancy and intervene through their offspring's 1-year birthday. Each mother-father dyad participating will be randomly assigned to one of two arms: 1. Obstetric and Pediatric Standard of Care + New Parent Engagement Intervention Arm or; 2. Obstetric and Pediatric Standard of Care + Safety Control Arm.
