Childhood obesity levels have stopped rising in many rich nations. Some claim it is proof that healthy-eating (67) are working,while others are (68) that it hides differences between rich and poor compatriots (同胞). Together with a research review that shows the (69) of childhood obesity rates,or even their decrease, in 15 countries (70) over the past decade,new data also showing obesity plateau (稳 定水平) was (71) at the International Congress on Obesity in Stockholm,Sweden last month. (72) , the claimed plateau is no excuse to (73) the battle against obesity,says Benjamin Rokholm. "The most important message is that the obesity epidemic is not (74) ," he says. "We’ve never had so many obese people in the world, so the plateauing should not be a soothing (使人宽心) message." Still, it will be (75) some: Rokholm has found that levels of obesity are actually (76) in some countries, most (77) in Japan. Boys are getting marginally lighter in Denmark, too, with the (78) of overweight and obese girls declining (79) in England, from 20.5 per cent in 2002 to 19.4 per cent in 2007. These figures should not be taken at face value, (80) , argues Tim Cole at University College London. He says the overall flattening trend (81) the true picture. Cole’s analysis of 5-to 10-year-olds in England found that overall there was indeed a leveling (82) , but that rates between rich and poor were (83) " If you separate out the data, you see that trends are still upwards in lower socioeconomic groups, but down in higher socioeconomic groups, so they (84) each other out to give the overall plateau," he says. So it is also clear that deeper (85) is needed and that the battle against obesity is far (86) won.
Vacations are a chance to take a break from work,see the world and enjoy time with family. But do they make you happier Researchers from the Netherlands set out to measure the effect that vacations have on overall happiness and how long it lasts. They studied happiness levels among 1,530 Dutch adults, 974 of whom took a vacation during the 32-week study period. The study,published in the journal Applied Research in Quality of Life, showed that the largest boost in happiness comes from the simple act of planning a vacation. In the study, the effect of vacation anticipation boosted happiness for eight weeks. After the vacation, happiness quickly dropped back to baseline levels for most people. How much stress or relaxation a traveler experienced on the trip appeared to influence post-vacation happiness. There was no post-trip happiness benefit for travelers who said the vacation was "neutral" or "stressful". Surprisingly,even those travelers who described the trip as "relaxing" showed no additional jump in happiness after the trip. "They were no happier than people who had not been on holiday," said the lead author,Jeroen Nawijn, tourism research lecturer at Breda University of Applied Sciences in the Netherlands. The only vacationers who experienced an increase in happiness after the trip were those who reported feeling "very relaxed" on their vacation. Among those people, the vacation happiness effect lasted for just two weeks after the trip before returning to baseline levels. "Vacations do make people happy," Mr. Nawijn said. "But we found people who are anticipating holiday trios show signs of increased happiness, and afterward there is hardly an effect." One reason vacations don’t boost happiness after the trip may have to do with the stress of returning to work. And for some travelers, the holiday itself was stressful. "In comments from people, the thing they mentioned most referred tc disagreements with a travel partner or being ill," Mr. Nawijn said. The research controlled for differences among the vacationers and those who hadn’t taken a trip, including income level,stress and education. However, Mr. Nawijn noted that questions remain about whether the time of year, type of tril: and other factors may influence post-vacation happiness. The vacationers who experienced post-vacation happiness were those______.
