This literature review examines the prevalence of childhood obesity in England since 2010, exploring key factors and causes. The review synthesizes findings from various studies, including the Health Survey for England, which reveals obesity and overweight statistics among children. It highlights correlations between lifestyle factors such as physical activity, screen time, dietary behavior, and the presence of a television in the bedroom, with increased BMI and obesity rates. Studies also point to the influence of home, school, and environmental factors, including the impact of fast food availability and unhealthy food sales in deprived areas. The review uses a three-step methodology for article selection and analysis, including the use of electronic databases like CINAHL and Google Scholar. The findings underscore the severity of childhood obesity as a public health concern, emphasizing the need for interventions and further research to address this growing issue.
