Objective: Some previous studies showed an association between low back pain (LBP) and sarcopenia. However, there are few studies investigating association both LBP and lumbar spine degeneration (LSD) with sarcopenia, simultaneously. The aim of this study is to investigate the association of LBP and LSD with sarcopenia using a nationwide survey in men over 60 years old.

Design: Cross sectional study Setting : Nation wide survey Fifth Korea National Health and Nutrition Examination Survey (2010-2011) Participants : We conducted a cross-sectional study using the fifth Korea National Health and Nutrition Examination Survey (2010-2011). Men ≥ 60 years of age were included.

Interventions: We defined sarcopenia as a modified skeletal muscle mass index value less than 20% of the participants. LSD was evaluated using a modified version of the Kellgren–Lawrence (KL) grade and was defined if the modified KL grade was two.

Main Outcome Measures: The risk of sarcopenia on LBP and LSD were investigated with multivariate logistic regression analyses. Model 1 was adjusted by age group. Model 2 was adjusted by age group, obesity, occupation, and physical activity.

Results: LBP was significantly associated with increased risk of sarcopenia (OR = 2.03 and OR = 2.17, respectively for Model 1 and 2). This association was maintained after adjusting for LSD. However, LSD was associated with decreased risk of sarcopenia (OR = 0.62 and OR = 0.61, respectively for Model 1 and 2). Conclusions: LBP was associated with increased risk of LBP in men ≥ 60 years old. It was also maintained after adjusting for LSD. However, LSD was associated with decreased risk of sarcopenia.

Level of Evidence: Level III
