METHODS: Forty-six older OA adults (16 men and 20 women) and forty-six older non-OA adults (20 men and 26 women) were recruited. The criteria of sarcopenia were: (1) muscle mass (ASM/ht2), cut-point was 7 kg/ht 2 for men and 5.7 kg/ht2 for women; (2) handgrip strength, cut-point was 26 kg for men and 18 kg for women; (3) gait speed, cut-point was 0.8 m/s for men and women. The Chinese Version of the Physical Activity Scale for the Elderly (PASE-C) were obtained by the standard procedures. The Food Frequency Questionnaire (FFQ) was used for assessing nutrition status. Comparisons between continuous variables, muscle mass, handgrip strength, gait speed, PASE-C were carried out by t-test. The comparisons between groups in regard to protein, calcium, vitamin C, and supplements were analyzed using the chi-square test. RESULTS: Among the 46 OA participants (mean age 64.8±8.3 years, height 1.59 ± 0.69 m, weight 63.4±11.6 kg, BMI 25.05 ± 3.69 kg/m2) and 46 non-OA participants (mean age 64.4 ± 6.39 years, height 1.6 ± 0.78 m, weight 61.38 ± 10.03 kg, BMI 23.8 ± 3.1 kg/m2), one woman participant in non-OA had sarcopenia. Muscle mass of OA was higher than non-OA in men (t = 2.08，p< .05). Handgrip strength, gait speed, PASE-C and FFQ were the same for OA and non-OA participants. As for muscle dysfunction, there was high percentage in women than men had muscle dysfunction. Muscle mass of OA was higher than non-OA in women (t = 2.788，p< .05). The number below the cut-point of handgrip strength was 5 and 11 for men and women re respectively, more than the number according to the sarcopenia criteria of handgrip strength. CONCLUSION: Sarcopenia and OA do not have direct relationship based on our result. Grip strength (<30 kg in men and <20 kg in women) of muscle dysfunction is a significant variable, therefore grip strength can be used as a pre-screening method for older adults in order to avoid further sarcopenia degeneration.
