Workplace Exposure to Petroleum-Based Lubricants Linked to Increased Multiple Sclerosis Risk
A recent study published in Neurology indicates an association between occupational exposure to petroleum-derived lubricants and a higher likelihood of developing multiple sclerosis (MS). The research, conducted in Sweden, involved 2,872 individuals newly diagnosed with MS and 6,122 individuals without the condition. Participants completed questionnaires detailing their work histories and potential contact with substances such as engine oil, hydraulic oil, cutting fluids, and concrete form oil.

After adjusting for various factors including age, sex, residential area, and smoking, individuals exposed to these lubricants had a 38% higher chance of developing MS. The risk further increased with longer exposure durations, with a 2% rise in odds for each additional year or hour per week of exposure. Common occupations among those exposed included metalworking, construction, ...
