Changing attitudes about sex
A new study by SDSU Psychology Professor Jean M. Twenge shows a generational shift in beliefs about sex and sexuality
2015-05-05
(Press-News.org) SAN DIEGO, Calif. (May 5, 2015)-- Acceptance of premarital sex is at an all-time high along with an acceptance of homosexuality, find researchers led by Jean M. Twenge from San Diego State University.
The researchers -- also including Ryne Sherman from Florida Atlantic University and Brooke E. Wells from Hunter College -- analyzed data from the General Social Survey, a nationally representative survey of more than 33,000 U.S. adults taken between 1972 and 2012. They found substantial generational shifts in attitudes toward non-marital sex and number of sexual partners. The results were published today in the Archives of Sexual Behavior.
"The changes are primarily due to generation -- suggesting people develop their sexual attitudes while young, rather than everyone of all ages changing at the same time," said Twenge, who is also the author of "Generation Me."
"This has caused a large generation gap in both attitudes toward premarital sex and number of sexual partners," she said.
The biggest change was between the Greatest Generation born in the early 1900s and the Boomers born in the 1940s-1950s, though 1980s-1990s born Millennials are more accepting of premarital sex than their 1960s-born GenX parents. After barely changing at all during the 1980s and 1990s, acceptance of premarital sex increased from 42 percent in 2000 to 58 percent in 2012.
Acceptance of same-sex sexual relations more than tripled from 13 percent in 1990 to 44 percent in 2012. Number of sexual partners (controlled for age) also shifted substantially, from 2.16 for the Greatest Generation to 11.68 for 1950s-born Boomers and 8.26 for Millennials.
"Millennials are more accepting of premarital sex than any previous generation, yet have had fewer sexual partners than GenX'ers. This is consistent with their image as a tolerant, individualistic generation accepting others' choices and making their own," Twenge said.
Twenge theorizes that these shifts in sexual attitudes and behavior are linked to growing cultural individualism in the U.S. "When the culture places more emphasis on the needs of the self and less on social rules, more relaxed attitudes toward sexuality are the almost inevitable result," Twenge said.
The entire article will be available today on the Archives of Sexual Behavior website.

Proteomics provides new leads into nerve regeneration
2015-05-05
Using proteomics techniques to study injured optic nerves, researchers at Boston Children's Hospital have identified previously unrecognized proteins and pathways involved in nerve regeneration. Adding back one of these proteins--the oncogene c-myc--they achieved unprecedented optic nerve regeneration in mice when combined with two other known strategies. The findings were published online April 30 by the journal Neuron.
Researchers have been trying for many decades to get injured nerves in the brain and spinal cord to regenerate. Various molecules have been targeted ...
Shedding light on rods
2015-05-05
"Imagine a tiny spotlight like those used in theatres but with a light ray measuring only a few nanometres, which shines light on a given spot but leaves everything else in the dark," explains Monica Mazzolini, SISSA research scientist, "That's how the optic fibres we used in our experiment work". Mazzolini, first author of a paper just published in PNAS, literally shut herself in a "darkroom" lit with infrared light only to stimulate rods, the light-sensitive cells of the retina (for night vision), with these extremely focused light beams in vitro. In their study, Mazzolini ...
Women hospitalized 60 percent more than men after emergency asthma treatment
2015-05-05
ARLINGTON HEIGHTS, Ill. (May 5, 2015) - While it may be a stereotype, it's also true that women seek medical care more frequently than men do. And a recent study shows that women with acute asthma who are treated in the emergency department (ED) are 60 percent more likely than men treated in the ED to need hospitalization.
The study, published in the Annals of Allergy, Asthma and Immunology, the scientific publication of the American College of Allergy, Asthma and Immunology (ACAAI), looked at the sex differences in patient characteristics, and risk of hospitalizations ...
Bystander CPR helps cardiac arrest survivors return to work
2015-05-04
DALLAS, May 4, 2015 -- More bystanders performing CPR contributed to more cardiac arrest survivors returning to work in a Danish study published in the American Heart Association journal Circulation.
In the largest study to date to examine return to work after cardiac arrest, researchers studied 4,354 patients in Denmark who were employed before they suffered out-of-hospital cardiac arrests between 2001 to 2011. Researchers found:
More than 75 percent of survivors who had a cardiac arrest outside a hospital were capable of returning to work.
Chances of returning ...
An unexpected role for calcium in controlling inflammation during chronic lung infection
2015-05-04
Many of us take a healthy immune system for granted. But for certain infants with rare, inherited mutations of certain genes, severe infection and death are stark consequences of their impaired immune responses.
Now, researchers at NYU Langone Medical Center have identified an important role for calcium signaling in immune responses to chronic infection resulting from Mycobacterium tuberculosis, the bacterium causing tuberculosis (TB).
Specifically, they determined that the immune systems in genetically altered mice lacking the critically important calcium channel ...
Primary care visits available to most uninsured, but at a high price
2015-05-04
Uninsured people don't have any more difficulty getting appointments with primary care doctors than those with insurance, but they get them at prices that are likely unaffordable to a typical uninsured person, according to new Johns Hopkins Bloomberg School of Public Health-led research.
And payment options are not very flexible, with only one in five people told they could be seen without paying the whole cost up front, suggests the new study published in the May issue of the journal Health Affairs.
"There's a discouragement factor for uninsured people when it comes ...
New screening technique could pick up twice as many women with ovarian cancer
2015-05-04
A new screening method can detect twice as many women with ovarian cancer as conventional strategies, according to the latest results from the largest trial of its kind led by UCL.
The method uses a statistical calculation to interpret changing levels in women's blood of a protein called CA125, which is linked to ovarian cancer. This gives a more accurate prediction of a woman's individual risk of developing cancer, compared to the conventional screening method which uses a fixed 'cut-off' point for CA125. The new method detected cancer in 86% of women with invasive epithelial ...
Racial differences in male breast cancer outcomes
2015-05-04
ATLANTA -- May 4, 2015 -- While black and white men under age 65 diagnosed with early-stage breast cancer received similar treatment, blacks had a 76% higher risk of death than whites, according to a new study. The study, published in the Journal of Clinical Oncology, found that the disparity was significantly reduced after accounting for differences in insurance and income.
Male breast cancer is a rare disease, accounting for less than 1% of all cancers in men and approximately 2% of all breast cancers in the United States. Black men have a higher incidence of breast ...
How oxidizing a heart 'brake' causes heart damage
2015-05-04
Oxidative stress has been long known to fuel disease, but how exactly it damages various organs has been challenging to sort out. Now scientists from Johns Hopkins say research in mice reveals why oxidation comes to be so corrosive to heart muscle.
A report on the results, published online May 4 in The Journal of Clinical Investigation, shows that oxidation inside the cardiac cells precipitates heart failure by disrupting the work of a heart-shielding protein called PKG, known to act as a natural "brake" against biological stressors like chronically elevated blood pressure, ...
Are scare tactics off the table for public health campaigns targeting HIV?
2015-05-04
Over the last ten years, public health campaigns in New York City around smoking, obesity, and HIV underwent a dramatic shift to use fear and disgust to spur behavior change, sometimes with the unintended consequence of stigmatizing affected populations. In a new article published in the May issue of the journal Health Affairs, scholars at Columbia University's Mailman School of Public Health explore the implications of this shift to fear-based campaigns in the present public health environment.
Beginning in 2005, the New York City Department of Health and Mental Hygiene ...
