United Kingdom adults who are overweight or obese keep their weight over time, which is associated with an increased risk of health complications and death. This is the result of a study published in the open access journal BMC Public Health.
Dr. Barbara Iyen, lead author, said, "We found that, despite widespread efforts to prevent and treat obesity, the majority of adults who are overweight or obese in the general population remain long-term. More effective weight control measures and interventions are urgent necessary in order to counter this increasing burden and the adverse health consequences associated with it. "
Researchers at the University of Nottingham looked at the evolution of the Body Mass Index (BMI) over time. The researchers observed stable increases in BMI scores in four groups of overweight and obese participants over an average of 10.9 years, with most maintaining their obesity levels over the long term.
The authors also found that people in the highest BMI group had a three times higher risk of heart failure and cardiovascular death than people in the overweight category. Those in the highest BMI category also had a three times higher risk of health death than those who were overweight. Participants in the two highest BMI groups did not have an increased risk of stroke or coronary heart disease compared to overweight participants. The authors noted higher levels of socio-economic disadvantage associated with increasing obesity severity and confirmed the need for measures that involve vulnerable and disadvantaged groups to combat obesity.
The study used patient records of 264,230 people, which were compiled from 790 general practices between 1999 and 2018 and are included in the UK Clinical Practice Research Datalink. Participants were divided into four groups defined in the World Health Organization BMI classifications as overweight, classes 1, 2 and 3 obesity.
The authors warn that BMI can vary between gender and ethnic group and that body muscles can weigh more than fat, giving the wrong impression of “healthy” weight. However, the use of the BMI routinely provides available weight and weight gain data collected by health professionals. The study lacked data on the participants' physical activity and food intake. More research is needed to determine the factors that contribute to weight maintenance, such as: B. Diet and physical activity choices, and how social and health policies can effectively combat obesity.
Overweight or obese adults often fail to realize they have a weight problem
