Low back symptoms defined as pain aching or stiffness on most days. BMI= body mass index. OA=osteoarthritis. SD=standard deviation. Proportions for symptoms, knee, hip and hand OA differ from column due to missing data. Anterior vertebral osteophytes coded based upon a subjects most severe superior or inferior lumbar level. Knee and hip OA defined as Kellgren-Lawrence (KL) score of 2-4. Hand OA defined as the presence of KL grade 2-4 in at least one distal interphalangeal joint and 2 other interphalangeal joints or carpometacarpal joints.
