Continued use of drugs and working conditions among truck drivers.

Few studies have been conducted on truck drivers with regard to their health problems, especially their drug consumption profile. This study aimed to determine the continuous use of drugs and to identify use-related professional characteristics among this category. A cross-sectional study was carried out with truck drivers parked at the sorting yard of the, Port of Paranaguá, Paraná. An interview to obtain socioeconomic data, data on health problems, working conditions and continued use of medication was performed. Of the drivers evaluated (n = 665), 21.1% reported a continuous use of some medication, mainly captopril (10.7%), metformin (10.3%), omeprazole (6.2%) and simvastatin (6.2%). Drivers with 16 or more years of professional experience (Prevalence Ratio [PR] 1.67; Confidence Interval [CI] 95% 1.11-2.51), truck owners (PR 1.38; CI 95% 1.03-1.86) and without formal labor contract (PR 1.49; CI 95% 1.11-2.00) had a higher prevalence of continuous use of medication. We noted that some working conditions play an important role in the continuous use of drugs by truck drivers.
