Table 6. HRs with 95% Confidence Intervals of Total Mortality between 1982 and 1999 within the Group of Overweight or Obese Participants Intending to Lose Weight by Reported Methods of Weight Loss, for Those Who Did Lose Weight between 1975 and 1981 Compared with Those Who Maintained Stable Weight.

The HRs were estimated by a fully adjusted Cox proportional hazards regression model. Out of the 398 participants included in this analysis, 153 intended to use diet alone, 95 exercise alone, 140 both methods, five neither of the two (intended to use drugs only), and the intended method was unknown in five participants. 12 (of whom two died) intended to use some medication.

The models were estimated on the basis of all participants who intended to lose weight with the method indicated, irrespective of whether they lost or gained weight, and the group maintaining weight was used as the reference group (HR of 1.00).

The fully adjusted model included, in addition, variables for hypertension, smoking, alcohol drinking, physical activity, life satisfaction, work status, and income.
