Objective: To determine the frequency of cardiovascular risk factors in offshore oil rig workers and to assess whether such risk may be associated with assigned tasks and work shifts in an oil company in Northern Peru. Materials and methods: We conducted a cross-sectional study, in which we collected data from the annual occupational medical examinations of workers in an oil company in Northern Peru. We reviewed the occupational records of 263 male workers over 40 years old: 27 office workers from daytime shifts, 89 office-field workers from daytime shifst and 147 sea–field workers from night shifts. Subsequently we determined the cardiovascular risk according to Framingham scores for both total cholesterol and LDL cholesterol, and we obtained the frequency of cardiovascular risk factors comparing these figures between the 3 groups. We also compared the mean Framingham risk l...
