PY - 2017 T2 - Obesity Medicine: Management of Obesity in Women's Health Care AB - The prevalence of obesity in childhood and adolescence has increased dramatically in the United States and in all developed countries since the early 1970s. Throughout childhood, obesity is defined as a body mass index (BMI) at or above the 95th percentile for age and sex using standard Centers for Disease Control and Prevention (CDC) growth curves; overweight is defined as BMI greater than the 85th to the 94th percentile. From National Health and Nutrition Examination Surveys (NHANES) data, the prevalence of obesity in 12- to 19-year-olds was 6.1% in 1971–1974 and increased serially at each evaluation to 20.5% in 2011–2012 (Figure 4-1).1 Overall, 23.9 million American children (32% of boys and 31.6% of girls) have a BMI at or above the 85th percentile and are classified as overweight or obese.2 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/19 UR - obgyn.mhmedical.com/content.aspx?aid=1139756847 ER -
