Table 3.

Association of 25-OH vitamin D concentrations with physical activity and HRQoL

Model	Unadjusted		Adjusted for age, sex, race, diabetes status, season and center
Model	β^a ± SE	P-value	β^a ± SE	P-value
AAS	1.34 ± 0.66	0.04	1.68 ± 0.74	0.03
MAS	1.00 ± 0.53	0.06	1.29 ± 0.60	0.03
SF-12 PCS	0.22 ± 0.41	0.60	0.60 ± 0.41	0.15
SF-12 MCS	0.81 ± 0.43	0.06	0.95 ± 0.44	0.03

β coefficient and SE values can be interpreted as: for a 25% change in 25-OH vitamin D concentration, the predicted variable (adjusted or maximum activity score, SF-12 scores) would change by β ± SE.
