    Wrong, says a new study, which has found that among adults 18 to 90 across the BMI continuum, having an apple shape increased the risk of death -- particularly death from cardiovascular disease. Even at BMIs above 30, where obesity begins, men and women whose waist-to-hip ratio identified them as more pear-shaped were less likely to die -- of any cause and of cardiovascular causes -- than those with similar BMIs who were apple-shaped.
