Girls exposed to regular high intensive physical exercises in childhood and adolescence delay AAM.

On the other hand, vegetable protein, fiber and vitamin D protect against rapid AAM.

Consuming animal protein (cow milk and meat) and soy-containing products promote early AAM through excessive energy intake and subsequent overweight.

A strong association between large waist circumference and early AAM has more predictive value than body weight for possible adverse outcomes in adulthood.

Higher body mass index (BMI) in girls as young as 36 months of age is associated to early menarche.

Menarche tends to be earlier in girls with more body fat and later in girls who exercise.

Non-hereditary factors like a childhood diet that is high in animal protein and low in vegetable protein may also be linked with earlier menarche. The contribution of genetic factors is about 57-82%. Age at menarche is determined in part by hereditary and non-hereditary factors.The AAM for Asian girls is 13.00 Р’В± 1.26 years. African American (12.2 years) and Hispanic (12.3) girls tend to have a significant earlier AAM.About 10% of girls reach the AAM at 11 years old or younger, while 90% of girls reach AAM at 13.75 years with a median age of 12.43 years. In the United States, the age at menarche (AAM) varies from 11.96 to 12.93 years.In the United States, average age at menarche declined from older than 14 years in 1877 to 12.8 years in 1947. From the 19th century through the mid-20th century, average age at menarche declined steadily in the United States and Europe, possibly due to improved nutrition and a reduction in strenuous physical activity.

Among ages 18-59, older age for men is associated with lower likelihood of his own orgasm for women it is associated with a higher likelihood of her own orgasm.For more, see Sexual Behaviors, Condom Use, and Sexual Health of Americans Over 50: Implications for Sexual Health Promotion for Older Adults (2010).More than one in five Americans over age 45 (22%) say they engage in self-stimulation at least once a week. 28% of Americans over age 45 report they had sexual intercourse once a week or more in the last six months, and 40%Р’В report having intercourse at least once a month.Teen sexual activity, contraceptive use, teen pregnancy, abortion, and STIs: American Teens' Sexual and Reproductive Health (2014).Average age of first intercourse, by gender, in the United States ( Read more Р’В»):.
