Multivariate analysis of factors related to the absence of musculoskeletal degenerative disease in middle‐aged and older people

Abstract

Aim Musculoskeletal degenerative disease (MSD; osteoporosis, knee arthritis and lumbar spondylosis) decreases the quality of life (QOL) of older people. The objective of the present study was to identify the factors related to the absence of MSD in multivariate logistic regression analysis. Methods The participants were 1034 volunteers (444 men, 590 women, mean age 63.5 years) in the Yakumo study. Osteoporosis (percentage of young adult mean ≤70%), knee arthritis (Kellgren–Lawrence grade ≥2), and lumbar spondylosis (Nathan class ≥3) were prospectively examined. Participants were divided into those with and without MSD. Age, sex, body mass index, muscle strength, gait ability, pain, body balance, spinal sagittal alignment, geriatric syndrome (locomotive syndrome, frailty and sarcopenia) and QOL (Short Form Health Survey) were compared between these groups to identify the factors associated with the absence of MSD. Results Significantly lower age, body mass index and pain; higher gait speed, grip and back muscle strength; more stable body balance; better sagittal spinal alignment; and lower rates of locomotive syndrome, frailty and sarcopenia were observed in the group without MSD (n = 445, 43%), with significantly better QOL (P < 0.0001). In multivariate logistic regression analysis adjusted for age and sex, lower body mass index (odds ratio [OR] 1.10, P < 0.001), lower spinal inclination (OR 1.08, P < 0.01), higher back muscle strength (OR 1.01, P < 0.05), no locomotive syndrome (OR 1.80, P < 0.05) and good body balance (OR: 1.12, P < 0.05) were significant factors for the absence of MSD. Conclusions Factors related to an absence of MSD are also related to good QOL, and should be a focus of health interventions in healthy middle‐aged and older people.

Amyotrophic Lateral Sclerosis: An Analysis of the Electromyographic Fatigue of the Masticatory Muscles

“…According to Wanshi Arnoni et al ( 2019), the median frequency spectrum in the electromyographic signal of the masseter and temporal muscles is lower than that in the control group without degenerative diseases, such as osteoporosis (Imagama et al, 2019). Our results concur with the findings of the literature, where the spectrum of the median frequency of the masseter and temporal muscles in the initial, medium, and final periods were shown to be smaller in the amyotrophic lateral sclerosis group.…”

Influence of Global Spine Sagittal Balance and Spinal Degenerative Changes on Locomotive Syndrome Risk in a Middle-Age and Elderly Community-Living Population

“…The subjects were healthy Japanese volunteers who attended a basic health checkup supported by the local government in 2018. This checkup, held annually in the town of Yakumo in a rural area of southern Hokkaido, Japan, comprises voluntary orthopedic, physical function, and internal medical examinations [ 12 ]. This study included patients who had undergone radiographic assessment and motor function testing and had completed a self-report questionnaire.…”
