| خلاصه مقاله | Aim: Generalized and asymptomatic joint hypermobility is prevalent and may be affected by various factors.
The aim of this study was to investigate the effect of factors, including age, gender, anthropometric characteristics,
physical activity level, limb dominance, and socioeconomic status on the generalized joint hypermobility in school
students in Tabriz city since 1396 to 1397.Methods. 782 school students (age ranged 7 to 18 years) including 350
girls and 432 boys were recruited through a cluster sampling method from different regions of Tabriz city based on
the ergonomic status. Anthropometric characteristics (body mass index, upper to lower limb ratio) were measured.
Physical activity level, limb dominance, and socioeconomic status were obtained by specific questionnaires. Beighton
test was applied to investigate the generalized joint hypermobility.
Results: There was a negative relationship between age and body mass index with beighton score. Also, body
mass index was correlated with physical activity level (negative relationship) and socioeconomic status (positive
relationship). Physical activity level had a positive relationship with beighton score. In general, beigthon score was
higher in girls than boys. In boys, beigthon score was higher in the left hand than the right hand (P<0.05). The
prevalence of general joint hypermobility with different cut-off points of beighton score was as follows: (cut-off
4:32.6% in girls and 25% in boys, 5:14% in girls and 10.2% in boys, and 6:6.6% in girls and 4.9% in boys).
Conclusion: Several factors may have different effects on the amount of generalized joint hypermobility. Nutritional
status, handedness, and physical activity level are important factors that need attention with respect to the risk of
developing generalized joint hypermobility syndrome in the future. |
