|---|---|---|---|---|
| r (95% CI) | P value | r (95% CI) | P value | |
| Blood pressure | ||||
| Systolic | 0.38 (0.30 to 0.46) | <.001 | 0.48 (0.40 to 0.56) | <.001 |
| Diastolic | 0.33 (0.24 to 0.41) | <.001 | 0.41 (0.31 to 0.50) | <.001 |
| Cholesterol | ||||
| Total | 0.20 (0.10 to 0.29) | <.001 | 0.01 (−0.10 to 0.11) | .89 |
| LDL | 0.16 (0.06 to 0.25) | .001 | 0.02 (−0.09 to 0.13) | .71 |
| HDL | 0.27 (0.18 to 0.36) | <.001 | 0.15 (0.04 to 0.25) | .006 |

Abbreviations: BMI, body mass index (calculated as weight in kilograms divided by height in meters squared); HDL, high-density lipoprotein; LDL, low-density lipoprotein.
There were 71 couples in which smoking status in both partners was not available. These couples showed no significant differences from the included 760 couples in age, education, household income, BMI, or waist circumference for both the women and the men, respectively (data not shown).
