| Variable | Odds ratio | 95% CI | p value |
|---|---|---|---|
| Father lived to 80+ | 1.84 | 1.35–2.51 | < 0.001 |
| Mother lived to 80+ | 1.70 | 1.25–2.32 | 0.001 |
| Farmer in 1930 | 1.67 | 1.21–2.31 | 0.002 |
| Born in the Northeast region | 2.08 | 1.27–3.40 | 0.004 |
| Born in the second half of year | 1.36 | 1.00–1.84 | 0.050 |
| Radio in household, 1930 | 0.87 | 0.63–1.19 | 0.374 |
