Abstract: BACKGROUND: Bridge employment (scheduled paid work after retirement
age) may promote successful aging and continued health, as work can be an
important component of daily physical activity. Appropriate work demands for
older adults are neither well-established nor well-applied, however, and
excessive loading or increased perceptions of discomfort may negate the health
benefits of work activity. OBJECTIVE: This study examined work status and musculoskeletal
discomfort (MSD) amongst older Albertans. METHODS: 1044 Albertans aged 55 years and older participating in an
organized 'Games' received a research package. Enclosed in the package were an
introductory letter, a return envelope, and modified versions of validated
questionnaires examining leisure and work activities, activity frequency, and
perceptions of musculoskeletal health. RESULTS: 228 respondents were classified into one of three
employment trajectory groups: fully retired, fully employed, or bridge
employed. Groups differed in age, and both employed groups more frequently
reported MSDs in all body areas. Bridge employed reported increased
'occasional' frequency of musculoskeletal injury risk factors, while both
groups reported similar overall ratings of work-related exertion. CONCLUSIONS: The increased MSDs reported by bridge employed adults
may be the result of irregularity of work activity and soft tissue loading.
Detailed examination of work demands and musculoskeletal injuries amongst
bridge employed adults could help define safer levels for less regular work
activity.
