Symptom development and timing of menarche: a longitudinal study

Area of Science:

• Psychiatry
• Developmental Psychology
• Public Health

Background:

• Somatic complaints are common in females and can persist into adulthood.
• The relationship between pubertal development and symptom reporting requires further investigation.

Purpose of the Study:

• To examine the longitudinal stability of self-reported somatic complaints in females.
• To investigate the association between the timing of menarche and symptom development.
• To identify patterns of symptom reporting across a nearly 30-year period.

Main Methods:

• Cross-sectional and longitudinal study design.
• Sample of 477 females from the general Swedish population.
• Person-oriented methodology for pattern analysis of somatic symptoms.

Main Results:

• Significant correlations between symptoms at ages 15 and 43, indicating stability.
• Early menarcheal timing was associated with symptom reporting at age 15.
• Consistent symptom reporting patterns and individual stability observed over nearly 30 years.
• No significant effect of menarcheal timing on symptom reporting at age 43.

Conclusions:

• Somatic complaint patterns show remarkable stability from adolescence to mid-adulthood.
• While early puberty influences adolescent symptoms, its long-term impact on symptom reporting diminishes by age 43.
• Individual differences in symptom reporting are consistent over time.
