Americans are more socially isolated than they were 20 years ago, and nearly a quarter of people said they had “zero”close friends with whom to discuss personal matters. More than 50 percent named two or fewer confidants (密友), most often immediate family members, the researchers said.
“This is a big social change, and it shows something that’s not good for our society，” said Duke University Professor Lynn Smith. She said that it showed there was a surprising drop in the number of close friends people had since 1985. At that time, Americans most commonly said they had three close friends whom they had known for a long time, saw often, and with whom they shared a number of interests. They were almost likely to name four or five friends and the relationships often sprang from their neighborhoods or communities (社区).
Ties to a close network of friends create a social safety net that is good for society, and for the individual. People were not asked why they had fewer intimate (亲密的) ties, but Smith said that part of the causes could be that Americans are working more, marrying later, having fewer children, and commuting (往返上班) longer distances. “It’s one thing to know someone and exchange e-mails with him. It’s another thing to say, ‘Will you give me a ride out of town with all of my possessions and pets?’ and ‘Can I stay with you for a couple or three months?’” Smith said. “Worrying about social isolation is not a matter of nostalgia (怀旧之情) for a warm and comfortable past. Real things are strongly connected with that，” added Harvard University Professor Robert Putnam, author of Bowling Alone, a book on the decline of American communities. He suggested flexible work schedules would allow Americans to tend both personal and professional lives.

PALO ALTO, California------"Switching off the television may help prevent children from getting fatter------ even if they do not change their diet or increase the amount they exercise," US researchers said last week.
A study of 192 third and fourth graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds(0.9kg) less over a one-year period than those who did not change their television diet.
"The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity," said Thomas Robinson, a pediatrician(儿科专家) at Stanford University.
"American children spend an average of more than four hours per day watching television and videos or playing video games, and rates of childhood being very fat have doubled over the past 20 years," Robinson said.
In the study, presented this week to the Pediatric Academic Societies‘ annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third.
Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continued their normal television viewing, even though neither group ate a special diet or took part in any extra exercise.
"One explanation for the weight loss could be the children unstuck to the television may simply have been moving around more and burning off calories," Robinson said.
"Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more," Robinson said.
