过去有研究认为,中年时身体脂肪过多会增加老年早亡的风险。但加拿大多伦多约克大学的研究人员发现,老年人适当增加身体脂肪会降低早亡的风险。研究人员对1988～1994年进行的加拿大第三次全国健康和营养调查所获得的数据进行了分析。被调查者涉及4437名男性和5166名女性,分析数据包括其身体指数、腰围、臀围以及腰与臀部的比例等。
Past research suggests that too much body fat in middle age increases the risk of premature aging. However, researchers at York University in Toronto, Canada, found that proper fattening in the elderly reduces the risk of premature death. The researchers analyzed data from the third National Health and Nutrition Survey in Canada, conducted between 1988 and 1994. The respondents involved 4437 males and 5166 females, the analysis of data including their body mass index, waist circumference, hip circumference and waist and hip ratio.
