To determine if low dietary calcium intake and disturbances in maternal calcium metabolism were associated with increases in blood pressure in late pregnancy.
To determine the incidence of type II diabetes and cardiovascular disease among Mexican-American and non-Hispanic whites in a 15 to 24 year follow-up of the San Antonio Heart Study 1 participants.

Also, to determine the number of 24-hour collections needed to characterize individuals with respect to the ratios of 24-hour to overnight excretion and to determine if the ratios of 24-hour to overnight excretion vary by age and other factors related to blood pressure.
