Low weight at birth, pubertal development and blood pressure in female adolescents
Abstract
Blood pressure was studied in a sample of 12-14-year-old healthy female adolescents, determining the condition of their menarche. The aim of the present research is to prove the known inverse association between the body weight at birth and blood pressure, to study the association between the body weight at birth and the age of the menarche and to prove a hypothesis on the relative size of the kidney with respect to the body volume and its association with the counts of the blood pressure. A descriptive observational and cross sectional study was performed in the sample. Results showed that adolescents with earlier menarche have higher counts of blood pressure as well as a greater body mass index. An alometric index in the relationship between the renal volume and the body mass index is also decreased in this group of adolescents. In those born with a low body weight, menarche appears almost a year before than in those born with a normal body weight. It is concluded that the low body weight at birth is in favour of , under some circumstances, an increase of the pubertal events, being accompanied by adaptative reactions in the economy, it was also determined that there is a significant correlation among these variables (p =0.014). This chain of events leads to an increase of blood pressure counts.Downloads
