Low back pain among taxi drivers: a cross-sectional study.

BACKGROUND

Low back pain (LBP) is a common occupational problem for drivers all over the world. However, few epidemiological studies have investigated LBP among taxi drivers.

AIMS

To investigate the prevalence of LBP and associated work-related factors among Chinese taxi drivers.

METHODS

A cross-sectional survey was administered to all participants. Using cluster sampling, questionnaires were collected from taxi drivers of three major taxi companies in Jinan, China. Univariate and multivariate logistic regressions were used to estimate the odd ratios (ORs) and 95% confidence intervals (CIs) among participants.

RESULTS

A total of 800 taxi drivers were invited to take part, with a participation rate of 90%. The 1-year period prevalence of LBP was 54%. Multivariate logistic regression analysis revealed that longer daily driving duration (OR 3.3, 95% CI 1.9-5.9), night shifts (OR 1.9, 95% CI 1.2-3.1) and increasing work years as a taxi driver (OR 1.7, 95% CI 1.2-2.5) were associated with increased risk of reporting LBP; while increased rest days per month (OR 0.8, 95% CI 0.7-0.9), longer sleep duration (OR 0.7, 95% CI 0.5-0.9) and more physical activity (OR 0.5, 95% CI 0.3-0.8) were significantly associated with decreased risk of reporting LBP.

CONCLUSIONS

The prevalence of LBP among professional taxi drivers in China was associated with a number of occupational features.
