According to foreign media reports, published a large study in the European Journal of Cardiology Journal of the European Society of Cardiology on Friday, which found that exercise does not eliminate the negative effects of overweight on heart health. “A person cannot be'fat but healthy',” said study author Dr. Alejandro Lucia of the European University of Madrid, Spain. "This is the first nationwide analysis to show that regular exercise cannot eliminate the adverse health effects of excessive body fat. Our findings refute the fact that an active lifestyle can completely negate the harmful effects of overweight and obesity Statement."
There is some evidence that fitness may reduce the adverse effects of overweight on heart health. Studies have shown that in adults and children, "fat but healthy" may be similar to "thin but unhealthy" cardiovascular health. Dr. Lucia said. "This has led to controversial recommendations for health policy that prioritize physical activity and fitness over weight loss. Our research attempts to clarify the link between activity, weight, and heart health."
The data used in this study is from Spain 527,662 working adults insured by a large occupational risk prevention company. The average age of the participants was 42 years and 32% were women.
Participants were classified as normal weight (BMI 20.0-24.9kg/m2), overweight (BMI 25.0-29.9kg/m2) or obese (BMI 30.0kg/m2 meters or more). In addition, they were grouped by activity level: 1) regular exercise, defined as the minimum amount of adult activity recommended by the World Health Organization (WHO); 2) insufficient activity (some moderate to vigorous exercise every week, but less Minimum activity level in WHO); 3) No exercise (no exercise). Cardiovascular health is determined based on the three main risk factors of heart attack and stroke, namely diabetes , high cholesterol and high blood pressure.
About 42% of the participants were normal weight, 41% were overweight, and 18% were obese. Most people do not like to exercise (63.5%), 12.3% do not exercise enough,24.2% of people exercise regularly. About 30% have high cholesterol, 15% have hypertension , and 3% have diabetes.
Researchers investigated the association between each BMI and activity group and three risk factors. At all BMI levels, any activity (whether it meets the WHO minimum standards or not) is associated with a lower likelihood of diabetes, high blood pressure, or high cholesterol compared to no exercise at all. Dr. Lucia said. "This tells us that everyone, regardless of their weight, should take physical exercises to protect their health."
Under all weights, as physical activity increases, the risk of diabetes and high blood pressure decreases . "The more exercise, the better, so walking 30 minutes a day is better than walking 15 minutes a day," he said.
However, overweight and obese participants have a greater cardiovascular risk than their normal-weight peers, regardless of activity level. For example, compared with inactive, normal-weight people, obese people who exercise are about twice as likely to have high cholesterol, four times as likely to develop diabetes, and five times as likely to develop high blood pressure. Times. Dr. Lucia said: “Exercise does not seem to make up for the negative effects of overweight. When men and women were analyzed separately, the overall situation of this finding was also observed.”
He concluded: “Fight against obesity and Not exercising is equally important. This should be a joint battle. Weight loss should be combined with the promotion of an active lifestyle and remains the main goal of health policy."
