Replication of physical capability and age acceleration in ALSPAC mothers with mean age 46.9

Variable	Model*	Regression coefficient (difference per year AA)	95% CI	p Value
Grip strength (kg)	Unadjusted	−0.021	−0.12 to 0.078	0.68
	Adjusted for height, BMI	−0.044	−0.14 to 0.052	0.37
	Adjusted for height, BMI, SEP	−0.034	−0.13 to 0.065	0.50
Chair rise speed (stands/min)	Unadjusted	0.0004	−0.0004 to 0.001	0.31
	Adjusted for height, BMI	0.0005	−0.0003 to 0.001	0.22
	Adjusted for height, BMI, SEP	0.0004	−0.0004 to 0.001	0.31
Balance time, eyes closed (log-seconds)	Unadjusted	0.067	−0.058 to 0.19	0.30
	Adjusted for height, BMI	0.083	−0.045 to 0.21	0.20
	Adjusted for height, BMI, SEP	0.088	−0.042 to 0.22	0.18

AA, age acceleration; ALSPAC, Avon Longitudinal Study of Parents and Children; BMI, body mass index; SEP, socioeconomic position.
*For each of the four physical capability measures, we ran three models, first unadjusted, then adjusted for height and BMI, then adjusted for height, BMI, smoking and education.
