Abstract: A retrospective case control study was carried out to determine the prevalence of joint hypermobility in flight attendants with musculoskeletal symptoms as compared with healthy volunteers to investigate the association between hypermobility and musculoskeletal symptoms in flight attendants. 30 flight attendants and 30 healthy volunteers of other occupations were recruited. The prevalence of musculoskeletal symptoms was evaluated by using the Nordic Musculoskeletal Questionnaire and the joint hypermobility was assessed by using the Beighton Scoring System. The most prevailing musculoskeletal symptoms occurred at the low back (60%), upper back (53%) and neck (33%) among the flight attendants while the volunteers were having similar trend though with lesser prevalence. The percentages were 43%, 30% and 13.3% at the low back, upper back and neck region respectively. 21 out of 30(70%) flight attendants were found to have joint hypermobility while only 9 out of 30(30%) control subjects had generalized joint hypermobility. However the percentage of flight attendants reporting musculoskeletal symptoms among those with hypermobility was not significantly higher than the corresponding percentage among flight attendants without such hypermobility. Such finding was also noted in the control group. Furthermore, no significant positive or negative correlations could be demonstrated between joint hypermobility and musculoskeletal symptoms in different regions in both the flight attendants as well as the control subjects. In conclusion, a significantly higher proportion of flight attendants with musculoskeletal symptoms are having joint hypermobility when compared with healthy volunteers. However we are unable to demonstrate significant positive or negative correlation between joint hypermobility and the occurrence of musculoskeletal symptoms in both the flight attendant group as well as the control group.
