Objective:
To investigate the association between mid-upper arm circumference (MUAC), calf circumference (CC) and all-cause mortality in a Chinese population.
Design:
Prospective cohort study.
Setting:
Eight long-term care facilities in central Taiwan.
Participants:
A total of 329 residents age 60 years and older (median 79.0 years, range 60-101; 139 men, 190 women) were enrolled.
Methods:
Anthropometrics and metabolic parameters were measured at the time of enrolment to the study. Mean MUAC and CC were 24.2±3.4 cm and 27.5±4.3 cm, respectively. Mortality data were obtained from the Department of Health in Taiwan.
Main Outcome Measure:
To identify the association between all-cause mortality and MUAC or CC.
Results:
There were 255 deaths during the 7-year follow-up period. After adjusting for age, sex, cigarette smoking, betel nut chewing, alcohol use, Karnofsky Performance Status Scale score, serum albumin level, hypertension and diabetes mellitus, subjects in the highest tertile of MUAC (27.8±2.2 cm) and CC (32.1±2.6 cm) had a significantly lower mortality rate than did subjects in the lowest tertile (MUAC 20.6±1.7 cm; CC 22.8±1.9 cm). The adjusted HR for all-cause mortality in the highest versus lowest MUAC tertile was 0.64 (95% CI 0.45 to 0.90). The adjusted HR for all-cause mortality in the highest versus lowest CC tertile was 0.51 (95% CI 0.35 to 0.74).
Conclusions:
MUAC and CC are negative predictors for all-cause mortality in older Chinese adults living in long-term care facilities. Participants with higher MUAC and CC had lower all-cause mortality.
