A new study led by the University of Gothenburg has found that men with a high body mass index (BMI) in their upper teens have an elevated risk of severe COVID-19 and can require hospitalisation later in life.The study was published in the journal, 'Obesity'.The study included data from the Swedish Military Service Conscription Register on 1,551,670 men in Sweden, born between 1950 and 1987, who were conscripted for military service in the period 1969-2005. At the outset, their height and weight were measured.Merging the conscription data with three Swedish medical registered -- the National Patient Register, the Intensive Care Register and the Cause of Death Register -- revealed a clear connection between BMI in adolescence and the risk of getting COVID-19, many years later, severely enough to require hospitalization. Even clearer was the link between BMI in the upper teens and needing intensive care for the disease.For the study, the scientists divided the men into six groups, from underweight (BMI 15-18.5) to three levels of normal weight (18.5-20, 20-22.5 and 22.5-25), followed by overweight (25-30) and obesity (BMI of 30 or more). Of the whole group during the study year (2020), 4,315 men with COVID-19 required hospitalization; 729 of them received intensive care and 224 died from COVID-19.Even for men who had been in the 22.5-25 BMI range in adolescence -- that is, within the normal weight range -- an elevated risk of needing hospital care for COVID-19 was found. The need increased successively with rising BMI results from the time of conscription 15 to 50 years earlier."At the population level, we can see that being overweight in the late teens raises the risk of hospitalization and intensive care for COVID-19. For those with teenage obesity, the risk of admission to an intensive care unit is more than twice as high as for those with a BMI of 18.5-20," said Josefina Robertson. A researcher at Sahlgrenska Academy, University of Gothenburg, a doctor specializing in infectious diseases at the Sahlgrenska University Hospital and the first author of the study.Her colleague Maria Aberg is an associate professor at the School of Public Health and Community Medicine at Sahlgrenska Academy, a physician specializing in general medicine in the regional health, part of Region Vastra Gotaland, and the last author of the study."Several studies have identified overweight as a risk factor for becoming severely ill with COVID-19, and we're now showing that overweight and obesity even in early life plays a part," Aberg said.The fact that obesity could be linked to an elevated risk of becoming severely ill from various infectious diseases, such as influenza, is well known. Obesity has an adverse impact on the immune system and worsens a person's propensity for inflammation, which can contribute to more serious infections.In the present study, the early BMI values were found to accompany the men up to middle age. This is evident from the data from health tests known as health-profile assessments, devised by the Health Profile Institute (HPI), for 151,693 of the participants."It's interesting to see that the men's BMI in adolescence is a risk factor for severe COVID-19 many years later. A high BMI in the men's teens also persisted into middle age, which is a trend that other studies have shown as well. That's why it's important to take preventive measures against obesity even at a young age, especially ahead of future viral pandemics," Josefina Robertson concluded.( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
