This study compared the incidence in cardiovascular disease (CVD) among American Indians in the Strong Heart Study who were and were not exposed to environmental tobacco smoke (ETS) in the home over time. They further stratified by dietary quality (High vs. Low) to determine whether diet modified or confounded the association between ETS and CVD. Researchers hypothesized that high quality diets containing antioxidants may minimize the effect of ETS on risk of CVD.
ETS Exposure Diet Quality Incidence of CVD per 1000 person-years
Yes High 18.63
Yes Low 32.52
Total 26.31
No High 17.99
No Low 26.14
Total 21.00
Required:
Calculate the crude (overall) and diet quality-stratified relative risk of CVD associated with environmental tobacco smoke exposure.
