Waist–hip ratio
WHR is used as a measurement of obesity, which in turn is a possible indicator of other more serious health conditions. The WHO states that abdominal obesity is defined as a waist-hip ratio above 0.90 for males and above 0.85 for females, or a body mass index (BMI) above 30.0. The National Institute of Diabetes, Digestive and Kidney Diseases (NIDDK) states that women with waist-hip ratios of more than 0.8, and men with more than 1.0, are at increased health risk because of their fat distribution.
Effects of advertising on teen body image
Additionally, a study of "Seventeen magazine" concluded that the models featured in this popular teen magazine were far less curvy than those portrayed in women's magazines. It was also noted that the hip-to-waist ratio had decreased in these models from 1970 to 1990.
