Aim: Evaluate if cardiovascular (CV) risk factors increase at a greater rate during the prediabetes (preDM) stage rather than the diabetes (DM) stage by sex.
Methods: We pooled data from the Atherosclerosis Risk in Communities Study and the Multi-Ethnic Study of Atherosclerosis. The CV risk outcome was the metabolic syndrome (MetS) severity z-score derived from components of waist circumference, HDL, triglycerides, SBP, and fasting glucose accounting for the weight of each component. The score was calculated for participants at visits 1 to 4 (3-year interval between visits) . We used linear mixed regressions to model the MetS z-score over time in men and women by levels of glucose (normal <100, preDM 100-125, DM ≥126 mg/dL) , adjusting for age, race, education, smoking, medication & cohort. A sex interaction was added to assess if the magnitude of risk factor changes over time differs by sex in each glucose level.
Results: Men and women had a greater rate of change in MetS severity during the preDM than the DM stage. Women had a significantly greater increase of MetS severity than men during the preDM stage, while men had a significantly greater increase in the DM stage than women.
Conclusion: A more rapid increase in MetS severity occurred in preDM than in DM. Women exhibited a faster increase in MetS severity compared to men during the preDM stage. Greater attention should be given to CV risk in women with preDM.
