一项新研究显示,65岁以上老年人的身体质量指数(BMI)稍高一点,寿命往往较长。世界卫生组织定义,如果BMI值在25以上,就是体重过重,BMI值在30以上就是肥胖。但澳大利亚迪肯大学的研究人员分析了20多万名65岁以上老年人从1990年到2013年的研究报告后发现,对老年人来说,如果BMI值在27.5左右,其死亡风险最低,如BMI值在22~23的正常体重范围,其死亡风险反而明显升高。研究人员指出,体重过重的老年人,与其将重点放在体重上面,不如更加重视饮食多样和营养均衡,感到饥饿时要
A new study shows older people over the age of 65 have a slightly higher BMI and longer lifespans. World Health Organization, if the BMI value of 25 or more, is overweight, BMI value of 30 or more is obesity. However, researchers at Deakin University in Australia analyzed more than 200,000 elderly over 65 years of age from 1990 to 2013 and found that for older adults, the risk of death was lowest if the BMI was around 27.5, such as BMI values in the 22 to 23 range of normal body weight, but significantly increased the risk of death. Researchers pointed out that overweight elderly, rather than its emphasis on weight above, it is better to pay more attention to the diversity of diet and nutritionally balanced, when you feel hungry
