Influence of childhood socioeconomic circumstances, height, and obesity on pulse pressure and systolic and diastolic blood pressure in older people.
This study assesses the association of childhood socioeconomic circumstances, height, and obesity with components of blood pressure. We selected 4009 people representative of the Spanish population aged 60 years and older, and estimated systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse pressure (PP) according to childhood social class, height, and obesity. No association was found between childhood social class and blood pressure. SBP showed an inverse gradient and DBP a direct gradient with height, although an independent association between height and DBP was found only in women. Stature was independently associated with increased DBP in women with central obesity, but there was no association between height and DBP in women without central obesity. Short stature was independently associated with increased PP. Body mass index and waist-to-hip ratio were independently associated with increased DBP in women, and waist-to-hip ratio was independently associated with increased PP in men, while waist circumference was independently associated with increased DBP and increased PP in women. These results do not support the assumed effect of socioeconomic circumstances in early life on blood pressure, which may depend on the context and/or study population. The relations observed between height and blood pressure support the hypothesis that PP could be a mediator of the association between short stature and increased cardiovascular risk. The relationship between obesity measures and components of blood pressure reinforces the recommendation to reduce body weight in order to reduce blood pressure.
