Early Weight Gain Might Mean Higher Blood Pressure Later

“Children who gain weight rapidly in the first five months of life and from ages 2 to 5 have higher blood pressure as adults, a new study finds. But rapid weight gain that early in life shouldn't be a major cause of worry for parents, said Dr. Yoav Ben-Shlomo, a professor of clinical epidemiology at the University of Bristol in England, and lead author of a report in the October issue of Hypertension. ‘In absolute terms, the relationship is moderate,’ Ben-Shlomo said. The difference in the study was about 2.5 points in systolic blood pressure, the higher number in a 120/80 blood pressure reading. Nevertheless, he said, the finding ‘adds to the scientific literature evidence that conditions not only in the womb but also in early childhood can predispose to various disease, such as diabetes. The information comes from a study done in Wales more than two decades ago to see whether giving pregnant women and children extra milk would help the children grow better. (It didn't have much effect.) As part of the study, children were weighed 10 days after birth, then at six weeks, three months, six months and nine months, and periodically in the following years. Looking at their blood pressure at age 25 or so, the researchers found not only the relationship between early weight gain but also weight at birth -- lower-weight newborns tended to have higher adult systolic blood pressure.”
