Community threat, positive parenting, and accelerated epigenetic aging: Longitudinal links from childhood to adolescence.

High community threat was associated with accelerated epigenetic aging in children.

• Data came from 2,039 children in the Future of Families and Child Wellbeing Study
• Sample was 49.7% female; 46.7% Black, 26.5% Hispanic, and 19% White non-Hispanic
• Community threat was measured from ages 3 to 9 (2001–2010)
• Epigenetic age acceleration was assessed at ages 9 and 15 (2007–2017) using DNA methylation

Positive parenting was associated with a slower pace of epigenetic aging.

• Children who received more positive parenting (e.g., warmth and encouragement) aged biologically more slowly
• Parenting was measured from ages 3 to 9 alongside home and community threat exposures
• The protective association of positive parenting on epigenetic aging was statistically significant (β = .026, p = .039)

The buffering effect of positive parenting on epigenetic age acceleration was moderated by level of community threat.

• Positive parenting reduced the pace of epigenetic aging in contexts of low, but not high, community threat (β = .026, p = .039)
• The protective effect of parenting was strongest when community threat was low or moderate
• At high levels of community threat, positive parenting did not significantly mitigate accelerated epigenetic aging

Home threat was measured as a distinct adversity exposure from community threat in the study design.

• Both home threat and community threat were measured from ages 3 to 9
• The study examined links from childhood (age 3–9) to adolescence (ages 9 and 15)
• The study used a longitudinal design spanning approximately 2001–2017

The authors concluded that multilevel interventions may be necessary to prevent the biological embedding of early life adversity.

• Family-level positive parenting alone was insufficient to buffer epigenetic aging under conditions of high community threat
• The findings highlight how both family and neighborhood environments influence children's long-term health
• Authors suggest interventions need to target multiple socioecological systems
