The Distribution and Associated Factors of SARC-F and SARC-CalF in Community-Dwelling Older Adults of Kinmen

Purpose This study aims to assess the distribution of SARC-F and SARC-CalF scores and identify associated risk factors among the elderly in Kinmen. Methods A community-based cross-sectional study was conducted in Kinmen in 2022 at the community care stations. The sample consisted of 305 individuals aged over 65. The outcome variable was the SARC-Ca1F score, which was categorized as normal (< 11) or abnormal ( ≧ 11). Chi-square, and binary logistic regression analysis were conducted for inferential statistical analysis. Results A total of 3.9% exhibited abnormal SARC-F values ( ≧ 4), and 14.4% had abnormal SARC-Ca1F values ( ≧ 11). Younger age, higher educational level, and BMI ≧ 27 were independently associated with a lower abnormal rate of SARC-Ca1F scores in older adults in Kinmen. When considering the interaction effect between MNA scores, marital status, age and educational level, it was observed that single elders showed a higher abnormal rate of SARC-Ca1F values (OR = 2.299, p = 0.023). Those using Kinmenese and Chinese or solely Kinmenese had a higher abnormal rate of SARC-Ca1F values compared to others, (OR = 5.902 and OR = 9.341, respectively). Individuals with a BMI ≧ 27 exhibited a significantly lower abnormal rate of SARC-Ca1F values compared to those with a BMI falling between 22-23.99, (OR = 0.174). Conclusions Among the elderly population in Kinmen, individuals with younger age, higher education levels, and BMI ≧ 27 exhibit a lower prevalence of sarcopenia. Conversely, individuals who are single or use Kinmenese as their native language show a higher likelihood of developing sarcopenia, highlighting unique demographic influences.
