Maywood
The were 743 subjects were sampled from Maywood, Il. There was no intervention.
Nigeria
There were 1188 Nigerian sampled from Igbo-Ora and Ibadan, Nigeria. There was no intervention.
Eligibility Criteria
Maywood cohort DNA samples were obtained from a larger cohort of families enrolled in the studies of blood pressure at Loyola University in Maywood, IL. The survey enrolled a representative random sample of the population between the ages of 18 and 74, regardless of obesity phenotype. A subcohort of 775 unrelated participants was selected and oversampled at the upper and lower ends of the BMI distribution to increase the power. Nigerian cohort Study participants were recruited from Igbo-Ora and Ibadan in southwest Nigeria as part of a long-term study on the environmental and genetic factors underlying hypertension. The sample comprised 1098 unrelated adults with normal or elevated blood pressure and 155 unrelated participants from Ibadan with elevated blood pressure recruited as controls in the Africa-America Diabetes Mellitus (AADM) study.
