Appendix 1—table 1. General linear model: effect of age at first birth on thoracic vertebral BMD for Tsimane women.
Parameter | Std. β | p |
---|---|---|
Age at 1st birth (years, loggeda) | 0.099 | 0.036 |
Age (years) | −0.665 | <0.001 |
Fat-free mass (kg) | 0.106 | 0.031 |
Adjusted R2 | 0.508 | |
N | 213 |
aAge at first birth is not normally distributed and is thus log-transformed (Std. βAge at 1st birth [years]=0.110, p=0.019, controlling for age and fat-free mass).
