Introduction: Neck pain is a highly prevalent disorder associated with significant disability. Few studies have been able to include a wide range of both personal and workplace risk factors in a single multivariate model and almost none have done so separately by gender.
Methods: Respondents to the 1998 Quebec Health and Social Survey who worked at least 25 hours/week were included in the current analyses: 5405 men and 3987 women. The case definition included those with neck pain during the previous 12 months interfering with usual activities fairly often or all the time. Personal and exposure variables for which at least one response category had a p value <0.25 in univariate analyses were retained for the three backwards stepwise multiple logistic regression models (men, women, total).
Results: Women had a significantly greater prevalence of neck pain (18.4%) than men (10.9%). In all three multiple logistic models, neck pain meeting the case definition was significantly associated with repetitive work, sitting posture, intimidation at work, high psychological job demands, and psychological distress. In men, neck pain was additionally associated with the absence of leisure time physical activity, the use of vibrating hand tools, whole body vibration, frequent exposure to difficult or tense situations with the public and inversely related to education level and the handling of heavy loads, while in women, neck pain was also associated with age over 40, being an ex-smoker, and exposure to unwanted sexual attention at work. All variables significant in one gender or the other were significant in the final model for the total population with the exception …
