Coexistence of osteoporosis, sarcopenia and obesity in community-dwelling adults – The Yishun Study

Objectives: To 1) report prevalence of ‘osteosarcopenia’ (OS) and osteosarcopenic obesity (OSO) entities using evidence-based diagnostic techniques and definitions, 2) examine if OSO offers additional predictive value of functional decline over its components, and 3) identify associated factors in a multi-racial Southeast Asian population. Methods: We performed a cross-sectional study of a representative sample of 542 community-dwelling adults (21e90 years old), and assessed anthropometry, cognition, functional performance, and selfreport sociodemographic, health and lifestyle questionnaires. Low muscle mass, and the Asian Working Group for Sarcopenia (AWGS) 2019 criteria, were used to assess sarcopenia. Obesity was defined using percentage body fat and fat mass index. Osteopenia/osteoporosis was determined using lumbar spinal bone mineral density. Associated factors were examined using logistic regression, and OSO’s value investigated using linear regressions with functional performance. Results: OS and OSO prevalence were 1.8% and 0% (21e59 years), 12.9% and 2.8% ( 60 years), 17.3% and 4.1% ( 65 years), and 25.5% and 7.0% (75 years), respectively. OSO entity as defined was not a significant predictor (P > 0.05) and did not improve explanations for functional decline over sarcopenia or sarcopenic obesity. Age, sex, race and body mass index (BMI) were associated with OS, while age, sex, race and alcoholism were associated with OSO. Conclusions: Our results do not support OSO as a distinct entity in relation to functional decline. Aside from biological age, sex, and race, amenable lifestyle factors such as BMI and alcohol intake are important variables that can influence the co-existence of osteopenia/osteoporosis, sarcopenia and obesity.

The purpose of this study was to gain insights into the physical demands of the sport of sepaktakraw and the physiological profiles of elite players. The temporal characteristics of matches (i.e. duration of rally, recovery, set and match) and physiological responses (i.e. heart rate (HR) and blood lactate [La]) of the players during matches were measured. Match duration ranged from 20.7 to 50.8 min. Mean duration of rallies and recovery between rallies were 5.5 and 9.8 s, where 73% of the rallies lasted < 6 s. [La] ranged from 1.2 to 8.8 mMo1·L(-1). These data suggested a dominant involvement of the anaerobic energy systems in sepaktakraw, in particular the alactic energy system. The mean HR of ~153 beats ·min(-1) indicated that the intensity of sepaktakraw match-play was moderate. National-level players (N = 22) were assessed for anthropometry, maximal oxygen uptake, anaerobic power and work capacity for 10 and 30 s, and vertical jump. There were no significant differences between the three positional roles (i.e. spikers, feeders and servers) in all the measures, except for height. Relative to elite athletes of other intermittent sports, the sepaktakraw player possessed excellent jumping power and ability to perform high-intensity anaerobic work, but lower aerobic fitness. The players` fitness attributes concurred well with their physiological responses and the temporal characteristics during match-play.
