American Girls Entered Puberty Later in the 1950s
1950s Puberty PSA
If you've been reading my blog for a while or you've read my book, you're familiar with the focus on obesity today being about "real" and "normal" women versus "unhealthy" which is disputed by "Health at Every Size" and similar movements. Yet how can anyone deny the impact of obesity on girl's and women's health when Early Puberty in Girls Linked to Obesity...Again?
In the 1950s girls entered puberty around ages 12-13 according to the PSA above. (Also notice that the narrator refers to some of the children as "fat.") Today?
The authors of the new study followed over 1,200 girls, starting at age 6 to 8, in three metropolitan areas: the San Francisco Bay Area, Greater Cincinnati, and New York City. They monitored breast development over the next 7 years. The median age of breast development was 8.8 for African-American girls, 9.3 for Hispanic girls, 9.7 for Caucasian girls, and 9.7 for Asian girls.
Although they didn't prove causality, “The obesity epidemic appears to be a prime driver in the decrease in age at onset of breast development in contemporary girls,” wrote the authors. Other suspected factors are toxins in our environment and food.
