Obesity is a global epidemic, with rising rates observed across both developed and developing nations, making global obesity trends & epidemiology a critical area of research. The World Health Organization reports alarming increases in obesity prevalence, with significant health implications, including rising incidences of diabetes, cardiovascular diseases, and certain cancers. Socioeconomic factors, urbanization, and the widespread availability of high-calorie foods have all played pivotal roles in driving these trends. Additionally, cultural shifts towards sedentary lifestyles and technological advancements that reduce physical activity have further contributed to the obesity burden. Epidemiological studies continue to track patterns across regions, identifying high-risk populations and underlying factors such as genetics and socioeconomic status. Understanding these trends is vital for informing public health strategies, optimizing interventions, and targeting at-risk communities to reduce the global obesity crisis.
