Abbreviations: BMI, body mass index, calculated as weight in kilograms divided by height in meters squared; BP = blood pressure.
SI conversion factors: To convert values for triglycerides to millimoles per liter, multiply by 0.01129; to convert values for cholesterol to millimoles per liter, multiply by 0.02586; to convert values for glucose to millimoles per liter, multiply by 0.05551.
a
All values are at the start of initial weight-loss program.
b
There was a larger proportion of black women assigned to the telephone condition than to the other groups (P = 0.04).
