ارتباط بين شلي عمومي مفصلي، وضعيت اجتماعي-اقتصادي و سطح فعاليت فيزيكي در دانش‌آموزان ايراني

هدف: شلي عمومي مفصلي به افزايش فيزيولوژيك در دامنه حركتي اطلاق مي‌شود كه تحت تاثير عواملي از جمله سطح فعاليت فيزيكي و وضعيت اجتماعي اقتصادي تغيير مي‌كند. هدف از مطالعه حاضر بررسي ارتباط بين شلي عمومي مفصلي با سطح فعاليت فيزيكي و وضعيت اجتماعي- اقتصادي در دانش‌آموزان ايراني بود. مواد و روش‌ها: 782 نفر دانش‌آموز دختر و پسر سالم (رده سني7- 18سال)، به روش نمونه‌گيري با روش خوشه‌اي مورد مطالعه قرار گرفتند. شلي عمومي مفصلي توسط معيار بي‌تون ارزيابي شد. سطح فعاليت فيزيكي و وضعيت اجتماعي- اقتصادي توسط پرسش‌نامه سنجيده شدند. افراد از طريق پرسش‌نامه با توجه به انجام ورزش‌هاي باشگاهي، ورزش ژيمناستيك و شركت در كلاس موسيقي مورد بررسي قرار گرفتند. يافته‌ها: نمره كلي بيتون با سطح فعاليت فيزيكي ارتباط مسقيمي داشت (01/0>P). رابطه‌اي بين وضعيت اقتصادي و اجتماعي و نمره كلي بيتون مشاهده نشد (05/0P) در حالي‌كه ارتباط بين نمره كلي بيتون و شركت در كلاس موسيقي به صورت معكوس معني‌دار شد (05/0>P). نتيجه‌گيري: طبق نتايج در جامعه ايراني مورد مطالعه ارتباطي بين شلي عمومي مفصلي و وضعيت اجتماعي- اقتصادي مشاهده نشد. هر چند با افزايش سطح فعاليت فيزيكي، شلي عمومي مفصلي افزايش يافت. با توجه به ارتباط بين فعاليت‌هايي از قبيل ورزش ژيمناستيك و شركت در كلاس موسيقي با شلي عمومي مفصلي، بررسي دقيق‌تر نقش اين عوامل در شلي عمومي مفصلي در رده سني دانش‌آموزان توصيه مي‌گردد.

Introduction: Generalized joint hypermobility is defined as a physiologic increase in the joint range of motion which is affected by various factors such as physical activity level and socioeconomic status. The aim of this study was to determine the relationship between generalized joint hypermobility with physical activity level and socioeconomic status in Iranian school students. Materials and Methods: In this study 782 school students (age ranged:7-18years) were allocated based on the cluster sampling method. The generalized joint hypermobility was determined according to the Beighton criteria. The level of physical activity and socioeconomic status were determined using questionnaires. Correspondingly, the participants answered a questionnaire concerning gym sport, sports in general and musical activity. Results: There was a significant correlation between the physical activity level and the Beighton score (P<0.01), but there was no significant correlation between Beighton score and the socioeconomic status (P >0.05). None of them were predictive of generalized joint hypermobility. There were significant and direct correlations between Beighton score and participation in the gym sports (P<0.05). Musical activity was reversely correlated with Beighton score (P<0.05). Conclusion: According to the results, there was no relationship between the generalized joint hypermobility with the socio-economic status in the study population in Iran. However, the generalized joint hypermobility was increased with increasing in the physical activity level. Because of the relationship between the generalized joint hypermobility with participation in gym sports and musical activity, it is recommended to examine the role of these factors on the generalized joint hypermobility in school students in details.
