Abstract
AimThis study investigated the prevalence of possible sarcopenia (PSA) in a large sample of middle‐aged and older adults, and determined the association between PSA, major chronic diseases and the number of chronic diseases.MethodsA total of 14 917 adults aged ≥40 years were included in the analysis. The handgrip strength and the five‐time chair stand test were used to assess PSA. The participants' major chronic diseases were divided into 14 categories. Four categories were created based on the participants' number of chronic illnesses: 0, 1, 2 and ≥3.ResultsThe present study found an overall prevalence of PSA of 23.6% among Chinese middle‐aged and older adults aged ≥40 years, with the risk increasing with advancing age. PSA was significantly associated with most categories of chronic diseases and multimorbidity. The closely independent associations were obtained for stroke; emotional, nervous or psychiatric problems; chronic lung disease, asthma, heart disease, hypertension and arthritis or rheumatism. Compared with participants with 0 chronic disease, those with two or more chronic diseases had higher odds for PSA. However, the association between PSA and the number of chronic diseases varied in different sex and age groups.ConclusionsThe findings suggest that PSA is associated with major chronic diseases among middle‐aged and older adults. People with two or more chronic diseases have a greater likelihood of PSA compared with those without chronic diseases, and the association between PSA and the number of chronic diseases largely depended on sex and age.
