Obesity is a true epidemic. According to World Health Organization statistics, worldwide obesity incidence has tripled since 1975, with 1.9 billion people being overweight and 650 million being obese. In the USA, 36.5% of the population is obese, and it is expected that by 2030, the incidence will climb to 50%. More alarming is the fact that childhood obesity rates have increased from 4% in 1975 to 18% currently.
Overweight and obesity are associated with higher rates of foot and ankle problems that in normal weight individuals. Additionally, certain conditions are more common in overweight people. These include heel pain, plantar fasciitis, midfoot pain, acquired flatfoot, arthritis, as well as edema (swelling),vein problems (including varicose veins and thrombophlebitis), balance problems, gait problems, knee pain, hip pain, back pain, and poor foot function. Diabetes is also associated with obesity.
Overweight children are especially prone to foot problems, especially flatfoot deformity. These conditions, if untreated, can lead to more serious problems in adulthood.
