Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Nurses Health Study
The Nurses' Health Study (NHS) was initiated in 1976 as a prospective cohort study, where 121,701 female registered nurses between the ages of 30 and 55 years were recruited from 11 US states.
Carbohydrate quality
This is an observational study examining the association between carbohydrate quality and coronary heart disease. The investigators used a variety of carbohydrate quality metrics to evaluate carbohydrate quality including carbohydrate, starch, total fiber, cereal fiber, fruit fiber, and vegetable fiber intakes, and the ratios of carbohydrate to total fiber, carbohydrate to cereal fiber, starch to total fiber, and starch to cereal fiber intakes.
Health Professionals Follow-Up Study
The Health Professionals Follow-up Study (HPFS) was initiated in 1986 and recruited 51,529 US men between the ages of 40-75.
Carbohydrate quality
This is an observational study examining the association between carbohydrate quality and coronary heart disease. The investigators used a variety of carbohydrate quality metrics to evaluate carbohydrate quality including carbohydrate, starch, total fiber, cereal fiber, fruit fiber, and vegetable fiber intakes, and the ratios of carbohydrate to total fiber, carbohydrate to cereal fiber, starch to total fiber, and starch to cereal fiber intakes.
