Abstract

Background

Actinic keratosis (AK) is a common keratinocyte intraepidermal neoplasia.

Objective

To assess AK prevalence and potential risk factors in patients attending Italian general dermatology clinics.

Materials & methods

This retrospective study was conducted on clinical data from consecutive white outpatients aged ≥30 years, attending 24 general dermatology clinics between December 2014 and February 2015. AK prevalence (entire population) and multivariate risk factor analysis (patients with current/previous AK and complete data) are presented.

Results

AK prevalence in 7,284 patients was 27.4% (95% CI: 26.4-28.4%); 34.3% in men and 20.0% in women (p<0.001). Independent AK risk factors in 4,604 patients were: age (OR: 4.8 [95% CI: 3.5–6.5] for 46–60 years, increasing with older age to OR: 41.5 [95% CI: 29.5-58.2] for >70 years), history of other non-melanoma skin cancers (OR: 2.7 [2.2-3.3]), residence in southern Italy/Sardinia (OR: 2.6 [2.1-3.0]), working outdoors >6 hours/day (OR: 1.9 [1.4-2.4]), male gender (OR: 1.7 [1.4-2.0]), facial solar lentigos (OR: 1.6 [1.4-1.9]), light hair colour (OR: 1.5 [1.2-1.8]), prolonged outdoor recreational activities (OR: 1.4 [1.2-1.7]), light eye colour (OR: 1.3 [1.1-1.6]), skin type I/II (OR: 1.3 [1.1-1.6]), and alcohol consumption (OR: 1.2 [1.0-3.3]). BMI ≥25.0 (OR: 0.6 [0.5-0.7]), regular sunscreen use (OR: 0.7 [0.6-0.8]), and a lower level of education (OR: 0.8 [0.7-1.0]) were independent protective factors.

Conclusions

AK prevalence was high in Italian dermatology outpatients. We confirm several well-known AK risk factors and reveal possible novel risk and protective factors. Our results may inform on the design and implementation of AK screening and educational programmes.
