"Background Mobility-related fatigue and low socioeconomic position predicts mobility limitations and disability in old age, but the interplay between these two factors is unknown. To evaluate whether mobility-related fatigue is a stronger risk factor for mobility limitations in certain socioeconomic groups, the aim of this study was to examine the combined effect of mobility-related fatigue and socioeconomic position on mobility limitations in a prospective study among older Danish men and women. Methods Multivariate linear regression models with combined exposure variables using generalised estimating equations were performed using four waves of data on 2874 individuals without mobility limitations at baseline from The Danish Intervention Study on Preventive Home Visits. Results Low socioeconomic position and mobility-related fatigue are risk factors for mobility limitations in old age. The combined exposure to both factors additionally increased the risk, but there was no synergy effect between the two. Notably, fatigue predicted mobility decline at 3-year follow-up among those aged 80?years at baseline with a mean difference in number of mobility limitations from the joint reference category (high socioeconomic position and no fatigue) of ?0.52, p<0.0001 among those in high socioeconomic position and ?0.96, p<0.0001 among those in low socioeconomic position. Conclusions Mobility-related fatigue is not a significantly stronger risk factor for subsequent mobility limitations among those with concomitant exposure to low socioeconomic position, compared with those with high socioeconomic position. Preventive strategies must focus on vulnerable groups of older people with low socioeconomic position as well as on individuals with fatigue."

"Objectives
To examine the impact of recurrent, as compared with single, reports of back pain on exit from paid employment over decades of follow-up.
Methods
The study sample was from the British Whitehall II Study cohort (n=8665, 69% men, aged 35–55 at baseline), who had provided information about their reports of back pain between 1985 and 1994. Data about exit from paid employment (health-related and non-health related exit, unemployment and other exit) were collected between 1995 and 2013. Repeated measures logistic regression models were fitted to examine the associations, and adjust for covariates.
Results
Recurrent pain was reported by 18% of participants, while 26% reported pain on an occasion and 56% did not report pain. Report of back pain on an occasion was not associated with health-related job exit, whereas recurrent pain was associated with such an exit (OR 1.51; 95% CI 1.15 to 1.99), when compared with those who did not report pain. These associations were somewhat stronger among middle-grade and lower-grade employees, while these associations were not seen among higher-grade employees. Differences in associations by age and psychosocial working conditions were small.
Conclusions
These results highlight the need for early detection of recurrent back pain to prevent exit out of paid employment for health reasons. As the risk varies by occupational grade, this emphasises the importance of identification of high-risk groups and finding ways to address their modifiable risk factors."
