ObjectivesThe global rise in overweight, obesity, and related diseases is undeniable; however, the pathogenesis of obesity and obesity-associated diseases is heterogeneous, with varied complications and a discordant response to treatment. Intriguingly, men have a shorter lifespan than women, despite being half as likely to be obese. This paradox suggests a potential gender disparity in the impact of obesity on mortality, with men potentially being more vulnerable to obesity-associated health risks.MethodsThis retrospective study utilized Global Burden of Diseases data from 204 countries/territories to bridge the knowledge gap in understanding gender disparities in obesity-related mortality. Outcomes were obesity-associated mortality, years of life lost, years lived with disability, and disability-adjusted life years (DALYs).ResultsIn 2019, the global overweight/obesity-related disease burden reached 160.2 million DALYs, with 5.02 million associated deaths. From 1990 to 2019, the age-standardized death rates increased in males (from 58.19 to 66.55 per 100,000 person-years, APC = 0.36%, 95% CI: 0.30 to 0.42%, P < 0.001), while females experienced a decrease in age-standardized death rates (from 59.31 to 58.14 per 100,000 person-years, APC = -0.22%, 95% CI: -0.29% to -0.14%, P < 0.001). Age-standardized DALYs increased more in males (1632.5 to 2070.34 per 100,000 years, APC = 0.74%, 95% CI: 0.70% to 0.78%, P < .001) compared to females (1618.26 to 1789.67 per 100,000 years, APC = 0.24%, 95% CI: 0.19% to 0.29%, P < 0.001). Disparities were more pronounced in countries with a higher socioeconomic status and predominantly affected younger populations.ConclusionsOverweight/obesity-related morbidity and mortality are higher among male sex. Identifying differences in pathogenesis, complications and treatment response is crucial to develop targeted interventions and equitable public health policies to combat this global burden.© 2024.
