Childhood obesity has tripled over the past 30 years, now affecting 12.7 million children in the US. One third of children are overweight or obese. Childhood obesity increases the risk of both acute health issues like high blood pressure, diabetes, and asthma, as well as chronic diseases including cardiovascular disease, cancer, and osteoarthritis. The major contributing factors to childhood obesity are inactivity, increased consumption of high caloric foods, and increased media/screen time. Prevention strategies include engaging in 60 minutes of physical activity per day, establishing healthy eating habits with more fruits/veggies and less sugar/fat, and limiting screen time especially close to bedtime.
