At the 5th study examination, the Framingham Offspring cohort participants had a mean age of 54 years (range 26-79 years) and a mean BMI of 27.2 kg/m2 (range 14-54 kg/m2). Fifty-six percent of the participants were women, 18% were current smokers, and 16% and 5% had a history of hypertension and diabetes, respectively.
Mean lycopene intake was 7.6, 7.9 and 8.0 mg/d at the 5th, 6th and 7th examinations, respectively.
Intake is the average of intakes assessed at the Framingham Offspring cohort 5th and 6th examinations and follow-up time is counted from the date of the 6th examination.
Model 1: adjusted for age and sex.
Lycopene intake was transformed using a natural logarithm. Consequently, the hazards ratios are interpreted as the relative risk for a 2.7-fold difference (i.e., a 1 unit difference on the natural logarithm scale) in lycopene intake.
Model 2: adjusted for age, sex, systolic BP, total cholesterol, total cholesterol/HDL ratio, BMI, smoking, number of packs per day, hypertension treatment, diabetes, saturated fat intake and energy intake.
Model 3: adjusted for variables in Model 2 plus β-carotene, flavonol, vitamin C and vitamin E intakes.
Intake is the average of intakes assessed at the Framingham Offspring cohort 5th, 6th and 7th examinations and follow-up time is counted from the date of the 7th examination.
Mean consumption of tomatoes and tomato-based products was 4.4, 4.4 and 4.6 servings/wk at the 5th, 6th and 7th examinations, respectively.
The hazard ratios reflect the relative risk for one serving per day difference in tomato product consumption.
