A study suggests that adults who have a sedentary lifestyle, despite being healthy may possess the same heart risks or strokes as an overweight person.
It has been found out by researchers that a normal-weight person who exercises 150 minutes of moderate activity weekly but spends most of the day sitting, has 58% lower risk of a heart attack or stroke than people who are overweight.
But at the same time, if the normal-weight person exercises very little and spends most of the time sitting, their risk of serious cardiac events wasn’t much different from that of overweight people.
The research was conducted on the people of age group 40 to 79. These participants did not had any history of heart-related diseases. The results showed that nearly 30% of the participants with a normal weight range had a high risk of heart attacks or strokes.
Arch Mainous, the lead study author of the University of Florida in Gainesville said, “Being at a normal weight is not sufficient to be healthy. This matters for patients because they may get a false sense of security by just looking at the number on the scale.”
He also added, “When people are sedentary - especially in middle age and beyond - they lose lean muscle mass and cardiorespiratory fitness”
Dr. Michael Hall, a researcher at the University of Mississippi Medical Center in Jackson said, “being in the normal weight BMI category is good but reducing sedentariness and increasing physical activity still has important benefits.”
He also added, “small things like taking the stairs, adding in a few brief walks in the day or other intermittent activities may help attenuate some of the risks associated with sedentary behavior.”
A sedentary lifestyle is also associated with high blood sugar in adults. People with a sedentary lifestyle have skinny fat. They have a body mass index within the normal range, but an increased proportion of fat to lean muscle.
This makes up more than 25 percent body fat in males and 35 percent in females. People with these characteristics have metabolic syndrome, including increased blood pressure, high blood sugar, and abnormal cholesterol levels.
The study suggests that a BMI score between 18.5 to 24.9 and sedentary lifestyle, increases the possibility of high risk for cardiovascular disease in people.
Researchers advise that people with a sedentary lifestyle should indulge in physical activities to reduce their risks of health problems.
