Aim This study investigated whether a high birth weight was associated with increased risk factors for cardiovascular disease when Swedish adults reached 34-40. Methods We studied 27 subjects born at Uppsala University Hospital in 1975-1979, weighing at least 4,500g, and compared them with 27 controls selected by the Swedish National Board of welfare with birth weights within ±1 standard deviations scores and similar ages and gender. The study included body mass index (BMI), blood pressure, lipid profile, haemoglobin A1c (HbA1c), C-reactive protein (CRP) and high frequency ultrasound measurements of intima-media thickness, intima thickness and intima:media ratio of the carotid and radial arteries. Results Subjects with a high birth weight did not differ from controls with regard to BMI, blood pressure, lipid profile, high-sensitivity CRP, HbA1c or carotid artery wall dimensions. However, their radial artery intima thickness was 37% greater than the control group and their intima:media ratio was 44% higher. Conclusion Our findings indicate that a high birth weight was associated with increased radial artery intima thickness, but not with other investigated cardiovascular risk factors, at 34-40 years of age. The clinical implications of these findings should be investigated further, especially in subjects born with a very high birth weight.
