Frequency of moles in a defined population
Journal of Epidemiology and Community Health
|March 1, 1985
Summary
The number of moles in adults has increased over time, mirroring the rise in malignant melanoma. This study analyzed mole occurrence in 872 adults, comparing it to earlier surveys.
Area of Science:
- Dermatology
- Epidemiology
- Public Health
Background:
- The incidence of malignant melanoma is rising globally.
- The epidemiology of common moles (nevi) is not well understood.
- Moles may be a key factor in understanding melanoma risk.
Purpose of the Study:
- To investigate the current occurrence of moles in adults.
- To compare mole frequency with historical data.
- To explore potential links between mole prevalence and melanoma incidence.
Main Methods:
- A community survey of 872 adults was conducted.
- Standardized criteria were used for mole assessment.
- Data were compared with two previous surveys from different locations and time periods.
Main Results:
- Adults averaged 15 moles (≥2 mm) and 39 moles (all sizes).
- Mole frequency decreased with age and varied by body site.
- Findings suggest an increase in mole frequency compared to earlier surveys.
Conclusions:
- The rising frequency of moles may correlate with increasing malignant melanoma rates.
- Further research into mole epidemiology is crucial for understanding melanoma.
- Mole occurrence patterns could provide insights into melanoma prevention strategies.
