Trojan said that they are unable to provide comparative information due to the sampling pool and the method used to conduct the surveys. However, previous studies conducted by the National Sleep Foundation did find contributing data such as the amount of sexual activity that occurs during the hours before bed.
Based on a previous NSF study, ten percent of both blacks and Hispanics reported that they are likely to have sex one hour before going to bed in comparison to four percent of whites.
Trojan’s study findings are a result of two surveys conducted in May including a national sample of 1,000 10-minute surveys. The results also included a 2,000-person sample from cities such as Atlanta, Chicago, Dallas/Ft. Worth, Houston, Los Angeles, Miami, New York, Philadelphia, San Francisco, and Washington D.C.
Researchers found that Atlanta was the most “sexually-charged” city.
