Mothers of small babies have high blood pressure

The relation between low birth weight and high blood pressure in adult life may be a consequence of fetal adaptation to undernutrition in utero. Both blood pressure and birth weight are, however, influenced by hereditary factors, and little information is available about the parents of the subjects in whom the relation has been observed. On p 834 Walker et al measured blood pressure in and obtained the birth weight of 452 young adults aged 16-26 years, having also obtained both of their parents' blood pressures. Mothers with higher blood pressure had offspring with both higher blood pressure and lower birth weight. Hereditary factors need to be considered with the programming effects of altered nutrition to understand the fetal origins of cardiovascular disease.
