The Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) study

Area of Science:

• Pediatrics
• Public Health
• Developmental Psychology

Background:

• Early life growth significantly impacts long-term metabolic and behavioral health.
• Infancy is a critical period for developmental plasticity, offering opportunities for interventions to alter obesity risk.
• The Intervention Nurses Starting Infants Growing on Healthy Trajectories (INSIGHT) study addresses the need for tested preventive interventions.

Purpose of the Study:

• To evaluate a responsive parenting intervention for the primary prevention of obesity in infants.
• To test the hypothesis that responsive parenting and feeding promote self-regulation and reduce overweight risk.
• To compare the parenting intervention against a home safety control group.

Main Methods:

• A longitudinal, randomized controlled trial involving 316 first-time mothers and newborns.
• Intervention delivered through home visits and clinic-based follow-ups until age 3 years.
• Primary outcome: BMI z-score at age 3 years; secondary outcomes include weight gain, sleep, maternal responsiveness, feeding style, and physical activity.

Main Results:

• Data collection ongoing; main results not yet available.
• Secondary outcomes include infant weight gain patterns, sleep hygiene, maternal responsiveness, feeding styles, and physical activity.
• Maternal and infant genetic data are collected to explore predictors and moderators of weight status.

Conclusions:

• The INSIGHT trial provides valuable data for informing obesity prevention strategies in clinical settings.
• Early life interventions targeting responsive parenting show promise for long-term health.
• Findings will contribute to understanding the impact of early experiences on health trajectories.
