A study analyzing data from 68.5 million people between 1980 and 2015 found that obesity prevalence doubled in over 70 countries and increased continuously in most others. In 2015, 107.7 million children and 603.7 million adults were obese. High BMI contributed to 4.0 million deaths globally, with nearly 40% occurring in non-obese individuals. Most deaths were due to cardiovascular disease. The disease burden related to high BMI increased since 1990, though the rate of increase has slowed due to reduced cardiovascular disease mortality. The study highlights the need for continued surveillance of BMI and evidence-based interventions to address obesity. It found that the prevalence of obesity has increased rapidly over the past three decades, outpacing the related disease burden. High BMI is a major risk factor for various diseases, including cardiovascular disease, diabetes, and cancers. The study also found that the lowest risk of death is associated with a BMI of 20 to 25. The study analyzed data from 195 countries and found that the prevalence of obesity varied significantly by country, age, and sex. The highest rates of obesity were observed in countries with high SDI levels. The study also found that the burden of disease related to high BMI increased globally, with cardiovascular disease being the leading cause of death and disability-adjusted life-years. The study concluded that the rapid increase in obesity prevalence and disease burden underscores the need for continued efforts to address this issue. The findings highlight the importance of implementing multicomponent interventions to reduce the prevalence and disease burden of high BMI.
