Table 2. Crude prevalence of sarcopenia in participants at the 2012 and 2017 surveys.

	Participants at the survey in 2012	Participants at the survey in 2017	P value
Overall subjects
Subjects with sarcopenia/total subjects	101/1,371	106/1,597
Crude prevalence, %a	7.4 (6.0–8.9)	6.6 (5.5–8.0)	0.44
Men
Subjects with sarcopenia/total subjects	43/601	38/706
Crude prevalence, %a	7.2 (5.2–9.5)	5.4 (3.8–7.3)	0.19
Women
Subjects with sarcopenia/total subjects	58/770	68/891
Crude prevalence, %a	7.5 (5.8–9.6)	7.6 (6.0–9.6)	0.94

Values are shown as the crude prevalence (95% confidence interval).

^aThe maximum gait speed was used for estimating sarcopenia because the data on usual gait speed were unavailable in the 2012 survey.
