Obesity Prevention in Children by Physical Health and Nutrition Student’s Name Institutional Obesity Prevention in Children by Physical Health and Nutrition Student’s Name Institutional Affiliation Obesity Prevention in Children by Physical Health and Nutrition Problem Description Over the last 30 years, the prevalence of childhood overweight and obesity has increased significantly. Currently, the World Health Organization (WHO) estimates the total number of children (aged below 18 years) suffering from obesity worldwide at 180 million.

Mainly, this study will analyze this issue among communities living in Clark County (Las Vegas), Nevada where obesity is a primary health concern among teenagers. The state of Nevada covers an area of 110,000 square miles with Las Vegas, its most populous city, housing over 1.35 million residents.
