4.2. Individual and lifestyle factors
In contrast to general perceptions, BMI, age, and experience were not associated with increased pain or distress in the present sample when examined independently. However, when included in the larger model, age had a significant negative effect on distress reporting, suggesting that older workers may experience less distress. This variation may be indicative of the complex interplay among variables involved in the painedistress relationship. Whereas the findings for age and experience may be explained by a survivor effect, the results for BMI are unclear. As reported, BMI in participants from sedentary job categories was so high, which may simply be due to a ceiling effect that prevented relationships from emerging. Alternatively, previous research involving law enforcement officers suggested that although BMI increased with psychological distress among females, there was no association among males [50]. This may reflect the limitations of BMI as a measure of body composition as it fails to distinguish between fat and lean body mass, which may have an impact on the ability to perform a particular task.
