A cohort of 414 older adults undergoing major elective surgery revealed striking results: those classified as overweight (BMI 25.0-29.9) had an astonishingly low 30-day all-cause mortality rate of just 0.8%. In stark contrast, normal-weight patients faced an 18.8% mortality rate, while underweight individuals experienced a serious 75% mortality rate. Adjusted analyses reinforced the protective association of being overweight against early postoperative mortality, challenging the notion that overweight status uniformly contributes to surgical risk in older populations.
