The bus driver is a profession vulnerable against LBP because while driving work is done in sitting position with very long time (11-14 hours). Early survey obtained bus driver who had LBP was suspected due to several factors. This study interested in conducting research on factors (age, years of service, exercise habits, BMI and vibration) related with LBP. Study design used explanatory research with cross sectional approach. The population in this study there were 66 bus drivers. Sampling technique used purposive sampling counted 33 drivers who worked from Jakarta - Kudus. Research instrument used was Visual Analogue Scale (measuring LBP), vibration meter (vibration), scales and microtoise (BMI), and questionnaires (years of service and exercise habits).

Meanwhile, there isn’t relationship between age, years of service, and BMI with LBP (p>0.05).The researcher recommend PO.
