Study Population
• 617,119 AARP members 50-71 years of age returned a comprehensive questionnaire assessing diet and lifestyle
• Participants resided in 6 states, CA, FL, LO, NJ, NC, PN, and 2 metropolitan areas, Atlanta and Detroit
• 566,401 completed the questionnaire satisfactorily
![Page 14: Journal Club Meena Meka MD. Topic Association of Coffee Drinking with Total and Cause-Specific Mortality](https://reader036.vdocuments.us/reader036/viewer/2022081519/56649dde5503460f94ad6c1b/html5/thumbnails/14.jpg)
Methods
• Participants completed the baseline questionnaire that assessed demographic and lifestyle characteristics and 124 dietary items
• Consumption of fruits, vegetables, red meat, white meat, unsaturated fat were adjusted for total energy intake with the use of the nutrient density approach
• Coffee consumption was assessed according to 10 frequency categories ranging from 0-6 or more cups a day
![Page 15: Journal Club Meena Meka MD. Topic Association of Coffee Drinking with Total and Cause-Specific Mortality](https://reader036.vdocuments.us/reader036/viewer/2022081519/56649dde5503460f94ad6c1b/html5/thumbnails/15.jpg)
Methods
• 96.5% of coffee drinkers provided information on whether they drank caffeinated or decaffeinated coffee more than half the time
• Participants were followed from baseline (95-96) until the date of death or 12/31/08.
• Coffee consumption was tabulated according to a number of dietary and lifestyle factors
• Hazard rations and 95% confidence intervals for mortality associated with coffee consumption were estimated with Cox proportional hazards regression models, with person-years as the underlying time metric
![Page 16: Journal Club Meena Meka MD. Topic Association of Coffee Drinking with Total and Cause-Specific Mortality](https://reader036.vdocuments.us/reader036/viewer/2022081519/56649dde5503460f94ad6c1b/html5/thumbnails/16.jpg)
Methods
• Risk estimates were presented seperately for men and women
• Multivariate models were adjusted for:– Age, BMI, race/ethnicity, level of education, alcohol
consumption, number of cigarettes smoked daily, use or nonuse of pipes or cigars, time of smoking cessation, health status , presence or absence of diabetes, marital status, level of physical activity, total energy intake, dietary consumption, vitamin supplementation , history of cancer in first degree relative and for women you of postmenopausal hormone therapy

Results
• Coffee consumption at baseline was associated with several other dietary and lifestyle factors
• As compared with persons who did not drink coffee, coffee drinkers were more likely to smoke cigarettes and consume more then 3 alcoholic drinks per day … and they consumed more red meat
![Page 18: Journal Club Meena Meka MD. Topic Association of Coffee Drinking with Total and Cause-Specific Mortality](https://reader036.vdocuments.us/reader036/viewer/2022081519/56649dde5503460f94ad6c1b/html5/thumbnails/18.jpg)
Results
• Coffee drinkers also tended to have a lower level of education; were less likely to engage in vigorous activity and reported lower levels of consumption of fruits, vegetables and white meat
• However, coffee drinkers, especially women who drank coffee, were less likely to report having diabetes.
• About 2/3 of coffee drinkers reported drinking predominantly caffeinated coffee
