Higher BMI in young Adults Found to Cause High BP and Enlarged Heart!

Chidhood and adolescent obesity is increasing worldwide due to dietary lifestyle, easy access to calories and lack of exercise.Studies in adults have shown "quite convincingly" that higher BMI likely increases the risk for cardiovascular disease or death from it.

A new study calledas “Children of the 90’s concluded that higher body mass index (BMI) is likely to cause" higher blood pressure and enlargement of heart.

Biological data was obtained from parents and offspring in Bristol since the children were born in 1991 to 1992. The children are now around 26 years old.

In 3000 participants of 17-year-old adults, the researchers found that young adults who had a higher BMI also had a higher blood pressure and a higher left ventricular mass index.

This was done using Mendelian randomization. Mendelian randomization mimics a randomized controlled trial.In a large population, there is a huge amount of genetic variation, where some people will have a genetic predisposition to have slightly higher BMI than others.This genetic predisposition is independent of diet and lifestyle. So, this allows researchers to assess whether a higher BMI may cause higher blood pressure, for example, as opposed to simply being associated with it.

After follow up of study participants when they were 21 years old, the researchers found that those who had a higher BMI also had higher blood pressure and a higher left ventricular mass as well as a higher cardiac output and stroke volume.

Efforts to reduce BMI to a normal, healthy range from a young age is likely to prevent later cardiovascular disease.

Bariatric (Weight loss) surgery is an effective tool in reducing the excess weight. This surgery is performed by laparoscopic approach. This surgery not only helps in weight loss but also helps in resolution of obesity associated co-morbid conditions like high blood pressure, diabetes mellitus and high cholesterol levels in blood.
