Association between sarcopenia at the baseline and incident poor quality of life (weighted data)

	Univariable model (OR, 95% CI)	p-value	Fully-adjusted modela (OR, 95% CI)	p-value
No sarcopenia	Reference	–	Reference	–
Sarcopenia	10.14 (6.29–16.35)	< 0.0001	5.82 (3.45–9.82)	< 0.0001

Data are reported as odds ratios (ORs) with their 95% confidence intervals (CIs)

Incident poor quality of life was defined as the lowest quartile in control, autonomy, self-realisation and pleasure-19 values, specific for each wave

^aFully-adjusted model included: age (as continuous variable); gender; years of education (as continuous variable); ethnicity (whites vs. non-whites); marital status (married vs. other status); smoking status (ever vs. never); Center for Epidemiologic Studies Depression Scale (as continuous variable); physical activity level (high vs. others); presence of multimorbidity (yes vs. no); control, autonomy, self-realisation and pleasure-19 values at baseline; changes in sarcopenia status during follow-up period
