Total cholesterol and all-cause mortality by sex and age: a prospective cohort study among 12.8 million adults.


ABSTRACT: It is unclear whether associations between total cholesterol (TC) levels and all-cause mortality and the optimal TC ranges for lowest mortality vary by sex and age. 12,815,006 Korean adults underwent routine health examinations during 2001-2004, and were followed until 2013. During follow-up, 694,423 individuals died. U-curve associations were found. In the TC ranges of 50-199 and 200-449 mg/dL, each 39 mg/dL (1 mmol/L) increase in TC was associated with 23% lower (95% CI:23%,24%) and 7% higher (6%,7%) mortality, respectively. In the age groups of 18-34, 35-44, 45-54, 55-64, 65-74, and 75-99 years, each 1 mmol/L higher TC increased mortality by 14%, 13%, 8%, 7%, 6%, and 3%, respectively (P < 0.001 for each age group), for TC ≥ 200 mg/dL, while the corresponding TC changes decreased mortality by 13%, 27%, 34%, 31%, 20%, and 13%, respectively, in the range < 200 mg/dL (P < 0.001 for each age group). TC had U-curve associations with mortality in each age-sex group. TC levels associated with lowest mortality were 210-249 mg/dL, except for men aged 18-34 years (180-219 mg/dL) and women aged 18-34 years (160-199 mg/dL) and 35-44 years (180-219 mg/dL). The inverse associations for TC < 200 mg/dL were stronger than the positive associations in the upper range.
