Abstract
Over half of US adults consume coffee (Coffea arabica) on a daily basis. Epidemiologic studies suggest coffee may prevent some chronic diseases and cancers. This analysis aims to quantify the potential health economic impact of coffee consumption in the US. A period life-table analysis was developed to estimate the total direct health care cost savings of coffee consumption associated with prevention of chronic disease and cancer over a one-year time horizon in the US. Age- and sex-specific population statistics, incidence, and mortality rates were used to model the prevalence and costs of chronic disease (Alzheimer’s, depression/suicide, diabetes, heart failure, Parkinson’s, stroke) and cancer (bladder, breast, colorectal, endometrial, esophageal, leukemia, liver, oral, pancreatic, prostate). Relative risks of chronic diseases and cancers by cups of coffee consumed daily were obtained from meta-analyses of prospective cohort and case-control studies. US daily coffee consumption, duration of disease, and attributable disease costs were obtained from the literature. The model was validated by comparing predicted disease-specific health care costs to estimates from published disease burden analyses. Probabilistic sensitivity analysis (PSA) was conducted. The model estimates that US coffee consumption prevents over 50,000 chronic disease and cancer deaths per year and results in an estimated health care savings of $33.4 billion per year (95% CI: $28.7bn, $38.3bn) of which $30.0bn is due to chronic disease and $3.4bn due to cancer. Cost savings were greatest for diabetes ($23.0bn), stroke ($2.7bn), depression ($1.6bn), heart failure ($1.4bn), and Alzheimer’s disease ($1.1bn). In the PSA breast cancer and colorectal cancer were the only disease states in which the 95% CI ranged over no cost savings. This analysis suggests a potential public health benefit and health economic savings associated with coffee consumption. Given the limitations of effectiveness data obtained from observational studies, additional research on the health effects of coffee is warranted.
