INTRODUCTION: Association of knee and @entity1643 with @entity25 is poorly understood. We aimed to clarify the independent and combined effects of these orthopedic symptoms on sleep in a large-scale general population. METHODS: Cross-sectional data about @entity1643 were collected for 9,611 community residents (53  14 years old) by a structured questionnaire. Sleep duration less than 6 h/d was defined as short sleep. Sleep quality and the presence of knee and @entity1643 were evaluated by dichotomous questions. Subjects who complained about knee or @entity1643 were graded by tertiles of a numerical response scale (NRS) score and a Roland-Morris disability questionnaire (RDQ) score respectively. Multivariate regression analyses were performed to determine the correlates of @entity25 and poor sleep quality. RESULTS: Frequency of @entity1 who complained of the orthopedic symptoms was as follows; @entity158 , 29.0%; @entity1643 , 42.0% and both knee and @entity1643 17.6%. Both knee and @entity1643 were significantly and independently associated with @entity25 ( @entity158 : odds ratio (OR) = 1.19, p<0.01; @entity1643 : OR = 1.13, p = 0.01) and poor sleep quality ( @entity158 : OR = 1.22, p<0.01; @entity1643 ; OR = 1.57, p<0.01). The group in the highest tertile of the NRS or RDQ score had the highest risk for @entity25 and poor sleep quality except for the relationship between the highest tertile of the RDQ score and @entity25 .(the highest tertile of the NRS: OR for @entity25 = 1.31, p<0.01; OR for poor sleep quality = 1.47, p<0.01; the highest tertile of the RDQ: OR for @entity25 = 1.11, p = 0.12; OR for poor sleep quality = 1.81, p<0.01) Further, coincident knee and @entity1643 raised the odds ratios for @entity25 (either of knee or @entity1643 : OR = 1.10, p = 0.06; both knee and @entity1643 : OR = 1.40, p<0.01) and poor sleep quality (either of knee or @entity1643 : OR = 1.61, p<0.01; both knee and @entity1643 : OR = 2.17, p<0.01). CONCLUSION: Knee and @entity1643 were independently associated with @entity25 and poor sleep quality. Further, they additively increased the correlation with these sleep problems in the general population.
