SI indicates special intervention; MI, minimal intervention; MET, metabolic equivalent; IQR, interquartile range.

a

All data and comparisons between groups are adjusted for study design (randomization of churches to SI or MI).

b

Percentages equal greater than 100% because some participants had more than one type of health insurance.

c

Physician diagnosis of myocardial infarction or angina or history of percutaneous intervention for coronary heart disease or coronary artery bypass surgery.

d

Myocardial infarction or sudden death of unexplained cause in father or brother before age 55 years or mother or sister before age 65 years.

e

For minutes of physical activity per day, medians and IQR are crude data; however, P values for these comparisons are adjusted for study design (randomization by church).
