Preliminary study among truck drivers in Turkey: effects of ultraviolet light on some skin entities.

In this study, we aimed to compare driver (left) and opposite (right) sides for some skin entities in drivers. We also evaluated the effect of occupational duration, age and skin type among this population. One hundred and forty-eight truck drivers were included in this study. Sun exposed areas were classified. Dermatological entities such as actinic keratosis, solar lentigo, seborrheic keratosis, melanocytic nevus, spider angioma, ephelid, basal cell carcinoma (BCC), squamous cell carcinoma, and melanoma were compared to driver and right sides. In addition, drivers were divided into two subgroups according to: (i) age (subgroups A1, 20-40 years, and A2, >40 years); (ii) occupational duration (subgroups O1, 1-10 years, and 02, >10 years); and (iii) skin type (subgroups S1, skin types I and II, and S2, skin types III and IV. Each of the two subgroups were compared with respect to the total prevalence (left and right sides) of lesions excluding the location. Seborrheic keratosis and lentigo solaris were found to be increased on the driver side of the face (P = 0.00) and ear (P = 0.013), respectively. Statistically significant increases of lesions on the driver side were determined according to the subgroups: melanocytic nevi were found to be increased on the driver side in A1 (P = 0.00), A2 (P = 0.00), O2 (P = 0.00), S1 (P = 0.00) and S2 (P = 0.006) groups; actinic keratoses were found to be significantly increased on the driver side in A2 and O2 groups (P = 0.03 for both).
