The study demonstrates that healthy lifestyle habits encompass a range of practices, including eating habits, hygiene, personal care, self -regulation, interpersonal relationships, physical activity, and rest, that promote a healthier life. The aim of this study was to identify the factors that contribute to childhood obesity in school -age students in the Puno-Peru region. This research employed a quantitative, non -experimental approach with a correlational explanatory design. A total of 315 students between the ages of 9 and 13 participated in this study. Of these, 195 were female (61.9%) and 120 were male (38.1%). A multiple linear regression model was used to examine the association between childhood obesity and healthy lifestyle habits, physical activity, hours of internet use, and hours of TV. Pearso & ntilde;s correlation was used to evaluate the results. The standardized (3 coefficients reveal that good healthy lifestyle habits ( beta = -0.353; p<0.001) and physical activity ( beta = -0.362; p<0.001) had the greatest negative impact on childhood obesity (general model: R-2 = 0.720; p < 0.001). In conclusion, maintaining healthy lifestyle habits is essential for controlling childhood obesity.
