Information was retrieved from the medical records of standardised lumbosacral spine plain films, age, and anthropometric measures of 1242 subjects. Acquired spondylolisthesis (ASL) was defined as non-lytic spondylolisthesis involving lumbar spines above L5. Questionnaires were used to gather information on demographic features, health behaviours, exercise, work related physical and psychosocial factors, and driving time profiles. Multiple logistic regression was used to model the odds ratio (OR) for prevalent ASL cases associated with personal and occupational factors.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    A total of 40 cases (3.2%) of ASL were diagnosed. Among those driving \u2a7d5 years, 6\u201315 years, and &gt;15 years, the estimated prevalence of lumbar spondylolisthesis was 1.1%, 2.4%, and 7.1% respectively. Results of multiple logistic regression suggested that taxicab driving &gt;15 years (OR\u200a=\u200a3.4, 95% CI 1.1 to 10.7, compared to driving \u2a7d5 years), age (OR\u200a=\u200a2.6, 95% CI 1.1 to 6.6 for age 46\u201355; and OR\u200a=\u200a4.8, 95% CI 1.8 to 12.9 for age &gt;55), body mass index \u2a7e25 kg\/m\n                    <jats:sup>2<\/jats:sup>\n                    (OR\u200a=\u200a2.2, 95% CI 1.1 to 4.6), and frequent strenuous exercise (OR\u200a=\u200a2.2, 95% CI 1.1 to 4.5) were significantly associated with higher prevalence of spondylolisthesis.
