Objective Demanding work conditions with multiple hazards can increase psychotropic drug use Assessment of the relationships of demanding work conditions with regular psychotropic drug use among employed people
Materials and methods The sample: All subjects aged 15 or more from 8,000 households randomly selected from the Lorraine (north-eastern France) Mailed self-administrated questionnaire: • socio-demographical characteristics, smoking habit, alcohol use • highly demanding occupational hazards • regular psychotropic drug use (fatigue, headache, sleeplessness, nervousness or anguish)
Study protocol (a) A request of participation by means of a questionnaire to ascertain the number of people in the household (b) Sending out standardized auto-questionnaires with a covering letter and a pre-paid envelope for reply (c) Sending a reminding letter without questionnaire (d) Sending questionnaires with a covering letter and a pre-paid envelope Communications addressed to the households at one month intervals The results were expressed in terms of adjusted odds ratios
Results 7,807 households contacted (193 communications lost, 2%) 3,460 households participated (44.3%) Every member participated for 86% of these households 6,214 participants The present study concerned the 2,826 employed people

Conclusions • Demanding work conditions may cause psychotropic drug use • Prevention should reduce occupational hazards, particularly when their number is high
