Psychosocial Stress Trajectories Are Associated With Puberty Timing: Findings From a 7-Year Cohort in Chongqing, China
Authors' conclusion
Chronic PS may be associated with delayed onset of several pubertal signs in both girls and boys. It may also accelerate testicular development of boys, indicating its varying impact on pubertal timing during early and later stages.
Study context
- Population
- Girls and boys in a Chinese cohort, Chongqing (2015–2022); pubertal outcomes examined every 6 months, stressful life events assessed 7 times732 girls and 688 boys
- Exposure
- PS trajectories vs "low, gradual decline" trajectory
- Outcome
- Puberty timing (pubertal outcomes)
Methodological details7-year cohort, repeated measurements, group-based trajectory model, Cox model adjusted for age, BMI and socioeconomic factors
