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 sleep and knee/low back pain 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 low back pain were evaluated by dichotomous questions. Subjects who complained about knee or low back pains 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 short sleep duration and poor sleep quality. RESULTS Frequency of participants who complained of the orthopedic symptoms was as follows; knee pain, 29.0{%}; low back pain, 42.0{%} and both knee and low back pain 17.6{%}. Both knee and low back pain were significantly and independently associated with short sleep duration (knee pain: odds ratio (OR) = 1.19, p{<}0.01; low back pain: OR = 1.13, p = 0.01) and poor sleep quality (knee pain: OR = 1.22, p{<}0.01; low back pain; OR = 1.57, p{<}0.01). The group in the highest tertile of the NRS or RDQ score had the highest risk for short sleep duration and poor sleep quality except for the relationship between the highest tertile of the RDQ score and short sleep duration.(the highest tertile of the NRS: OR for short sleep duration = 1.31, p{<}0.01; OR for poor sleep quality = 1.47, p{<}0.01; the highest tertile of the RDQ: OR for short sleep duration = 1.11, p = 0.12; OR for poor sleep quality = 1.81, p{<}0.01) Further, coincident knee and low back pain raised the odds ratios for short sleep duration (either of knee or low back pain: OR = 1.10, p = 0.06; both knee and low back pain: OR = 1.40, p{<}0.01) and poor sleep quality (either of knee or low back pain: OR = 1.61, p{<}0.01; both knee and low back pain: OR = 2.17, p{<}0.01). CONCLUSION Knee and low back pains were independently associated with short sleep duration and poor sleep quality. Further, they additively increased the correlation with these sleep problems in the general population.", "link"=>"http://www.mendeley.com/research/knee-pain-low-back-pain-additively-disturb-sleep-general-population-crosssectional-analysis-nagahama", "reader_count"=>22, "reader_count_by_academic_status"=>{"Unspecified"=>2, "Professor > Associate Professor"=>2, "Librarian"=>1, "Researcher"=>5, "Student > Doctoral Student"=>1, "Student > Ph.
