Final answer:
The provided information does not specify the percentage of the population with an asthenic body habitus. However, it highlights obesity rates, with 36 percent of U.S. adults over 20 classified as obese and 33 percent as overweight in 2010, and notes the importance of fat distribution in assessing health risks.
Step-by-step explanation:
The exact percentage of the population with an asthenic body habitus is not provided in the provided data. However, it is possible to discuss related issues such as obesity rates and body fat distribution. Obesity is a major health issue, and its prevalence has been increasing over the years. According to the U.S. Centers for Disease Control and Prevention, nearly 36 percent of adults over 20 years old were obese as of 2010, with an additional 33 percent being overweight. This leaves approximately 30 percent of the population at a healthy weight. Fat distribution also plays a role in health risks, with individuals having a higher waist-to-hip ratio being at a greater risk for obesity-associated diseases.
Metabolism and Obesity is an area closely related to understanding how body types and lifestyle choices contribute to the population's overall health status. With differing body shapes—such as android (apple) and gynoid (pear) shapes—affecting health risk profiles, waist-to-hip ratio measurements provide greater insights into health risks compared to BMI alone.
