Rapid Weight Gain in Babies may Lead to High BP in Adulthood

A new study says that babies who gain weight rapidly within five months of birth are at an increased risk of having high blood pressure in adulthood.

The researchers examined first five years of life of the babies and found that babies that gain weight more rapidly in the first five months after birth and from about ages 2 to 5 years have higher systolic blood pressure in young adulthood.

Obesity - Causes, Symptoms, Diagnosis, Complications, Treatment
Obesity is a condition where there is excess accumulation of body fat which poses a risk to the health of the individual. It can affect children and adults.

Immediate weight gain after birth was also linked higher adult diastolic blood pressure.

Systolic blood pressure is the first number in a blood pressure reading and represents the pressure in the arteries while the heart contracts. Diastolic blood pressure represents the pressure when the heart relaxes between beats.

"Changes in immediate (or the first five months) post-natal weight gain and childhood weight gain were associated with small changes in systolic blood pressure (around 1-1.5 millimeters of mercury [mmHg]) that were probably not due to chance," said Yoav Ben-Shlomo, lead author of the study and professor of clinical epidemiology in the Department of Social Medicine at the University of Bristol, U.K.

Atkins diet is a low carbohydrate diet and aids in weight loss. It was developed by Robert Atkins.

"At an individual level, these changes would not be very important but in public health terms they are relevant," Ben-Shlomo added.

The researchers evaluated 679 adults (about age 25) whose growth patterns were tracked as infants as part of the Barry Caerphilly Growth Study. Measurements had been recorded at 14 points between birth and age five.

High Cholesterol | Hypercholesterolemia - Causes, Symptoms, Diagnosis & Treatment
High cholesterol level in blood are a risk for heart disease and stroke. They get deposited in the wall of the arteries and clog the circulation posing a threat to life.

They researchers found that weight gain occurring between 0 and 5 months and 1 year, 9 months to 5 years made the most difference.

"When trying to understand why some people get high blood pressure in later life, we need to consider a life course approach that considers early life as well as adult life risk factors such as dietary salt and obesity," Ben-Shlomo said.

Low Calorie Diet | Low Calorie Foods
Low calorie meals or diet include foods that are high on nutritional content and yet have fewer calories. Updated information about low calorie diet or low calorie foods and its health benefits.

"If children put on more post-natal weight today than they did in the past, then we could better predict that the burden of high blood pressure will increase in the future. Hypertension, in turn, is associated with an increased risk of heart disease and stroke," Ben-Shlomo added.

The findings are reported in Hypertension: Journal of the American Heart Association.
