Barker recently hypothesized that factors affecting prenatal and infant growth are related to adult blood pressure and CVD mortality. Predictions from Barker's hypothesis in regard to infant feeding were tested among a sample of 3 or 4 year old children. The relationship of infant-feeding characteristics (duration of breast-feeding, times of introduction of high fat, high carbohydrate, high potassium foods and table salt) to indicators of cardiovascular functioning (resting blood pressures and heart rates, and heart rate response to graded activity) while controlling for anthropometric (height, sum of seven skinfolds, BMI) and demographic (ethnicity, gender, social status) characteristics revealed that infant-feeding practices were not related to CV functioning in the predicted directions among this sample of 3 or 4 year old children. Furthermore, the positive relationship between height and systolic blood pressure was inconsistent with the Barker hypothesis.
