Estimated mean weight and weight gain after 20 years of following five cigarette smoking strategies, 2001 smokers from the Framingham Heart Study a
| Strategy | Mean 20-year weight, kg (95% CI) | Mean 20-year weight gain, kg (95% CI)b | Cumulative % intervened on | Average % intervened on |
|---|---|---|---|---|
| Smoking cessation | 75.2 (73.5, 76.6) | - | 100.0 | 17.6 |
| Smoke 5 cigarettes per day | 73.4 (71.9, 74.6) | 1.8 (0.8, 2.8) | 100.0 | 80.3 |
| Smoke 10 cigarettes per day | 71.9 (70.3, 73.4) | 3.3 (1.7, 4.6) | 100.0 | 80.9 |
| Smoke 15 cigarettes per day | 70.8 (69.3, 72.4) | 4.4 (2.5, 5.8) | 100.0 | 80.7 |
| Smoke 20 cigarettes per day | 70.2 (68.7, 71.8) | 5.1 (3.1, 6.6) | 100.0 | 78.6 |

Estimated using the parametric g-formula with fixed covariates: age, height, occupation, education, and marital status; and time-varying covariates: lagged weight, cigarettes smoked per day, systolic blood pressure, total cholesterol, and cardiovascular disease diagnosis.

20-year weight gain post smoking cessation, with the cigarette smoking strategy as reference.
