More 70-year-olds are having good sex more often, Swedish researchers said on Tuesday in a finding bound to bring a smile to many an aging baby boomer.

They found 70-year-olds of both sexes are having more sex than they did 30 years ago, and many more women report being satisfied with their sex lives.

"Attitudes are more open-minded and positive today, at least in the elderly themselves," said Nils Beckman of the University of Gothenburg in Sweden, whose study appears in the British Medical Journal.

Beckman and colleagues interviewed four groups of 70-year-olds in Sweden about their sex lives between 1971 and 2001. They found that 68 percent of married men said they were having sex in 2001, up from 52 percent in the early '70s.

The number of married women having sex rose to 54 percent in the group interviewed in 2000-2001, up from 30 percent in the early 70s.

And 12 percent of unmarried women interviewed in 2000-2001 said they were having sex, up from less than 1 percent in the early '70s. The number of women reporting high sexual satisfaction also increased, with more women reporting an orgasm during sex and fewer reporting never having had one.

Interestingly, the number of men reporting low sexual satisfaction rose. Beckman said in an e-mail this might be because men are now more open in talking about sexual failure.

Overall, he said the changes reflect shifting attitudes about sex in Western societies over the past half century.

"Hopefully it will inspire elderly people to seek help if having sexual problems, and make doctors and other health professionals aware that even elderly people can be or would like to be sexually active," Beckman said.

瑞典研究人员在本周二表示，如今越来越多的7旬老人更加“性福”，这个研究一定会让许多日渐衰老的婴儿潮一代感到愉快。

他们发现，与30年前相比，70多岁老年人的性生活都有增加，并且更多女性对自己的性生活表示满意。

瑞典哥德堡大学的尼尔斯•贝克曼说：“如今的性观念越来越开放积极，至少在老年人中是如此。”他的这项研究在《英国医学期刊》上发表。

贝克曼和他的同事对瑞典四组70多岁的老人在1971年至2001年之间的性生活进行了采访。他们发现68%的已婚男性表示他们在2001年有过性行为，较70年代初的52%有所上升。

在2000年至2001年的调查组中，已婚女性拥有性生活的人数上升至54%，高于70年代初的30%。

此外，在2000年至2001年被调查的未婚女性中，12%的人表示她们拥有性生活，而70年代初，这个比例还不到1%的比例。越来越多的女性表示她们对自己的性生活高度满意，更多女性称有过性高潮，极少数人表示从未有过高潮。

有趣的是，宣称性生活满意度低的男性人数上升了。贝克曼在一封邮件中说，这可能是因为现在男性能够更加坦率的讨论性障碍。
