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.
Southern hip hop
The height of Southern hip-hop was reached from 2002 through 2004. In 2002, Southern hip-hop artists accounted for 50 to 60 percent of the singles on hip-hop music charts. On the week of December 13, 2003, Southern urban artists, labels and producers accounted for six of the top 10 slots on the "Billboard" Hot 100: OutKast had two singles, Ludacris, Kelis (produced by The Neptunes), Beyoncé and Chingy (on Ludacris' Disturbing Tha Peace label). In addition to this, from October 2003 through December 2004, the number one position on the "Billboard" Hot 100 pop chart was held by a Southern urban artist for 58 out of 62 weeks. This was capped by the week of December 11, 2004 when seven out of the top ten songs on the chart were held by or featured Southern urban artists. In 2004, Vibe magazine reported that Southern artists accounted for 43.6% of the airplay on urban radio stations (compared to 29.7% for the Midwest, 24.1% for the East Coast and 2.5% for the West coast). Rich Boy from Mobile, Alabama was successful in 2007 with his debut album. Since the early 2010s, many contemporary hip hop artists have become mainstream. The prevailing genre in contemporary hip hop is trap, which originated from the South. Rappers from across the country have implemented trap into their music. Kendrick Lamar's 2017 album DAMN incorporated elements of trap.
