Context
Cardiometabolic conditions increase in midlife but early customized prevention strategies are not established for such women.
Objective
To characterize, and identify factors related to, constellations of cardiometabolic risk components longitudinally in multi-racial/ethnic midlife women.
Design
We conducted a prospective longitudinal, multi-ethnic cohort study of 3,003 midlife women, undergoing the menopausal transition (MT). Metabolic syndrome (MetS) meant having at least 3 of 5 components: high fasting triglyceride (hTG), low high density lipoprotein cholesterol (lHDL), high fasting plasma glucose (hGluc), large waist circumference (Ob), and hypertension (HTN). We described the patterns of constellations and estimated hazard ratios (HRs) for constellations at 1) incident MetS and 2) recovery from MetS, using multivariable-adjusted Cox regression.
Setting
Seven U.S. sites
Participants
1412 non-Hispanic White, 851 Black, 272 Japanese, 237 Hispanic, 231 Chinese women
Exposures
Race/ethnicity, lifestyle factors, MT stage
Main Outcomes Measures
Cardiometabolic constellations; incident MetS; MetS recovery
Results
Central obesity was the most frequent component. Having no components was the most frequent (31%) baseline constellation. Physical activity (HR = 1.68, 95% CI: 1.06-2.68) and lower caloric intake (HR = 0.96; 95% CI: 0.93-0.99, per 100 Cal/day) were associated with recovery from MetS. Ob/hTG/lHDL (18%), Ob/HTN/lHDL (16%), and Ob/HTN/hGluc (14%) were frequent incident constellations. Physically active women had 26-62% lower hazards of incident MetS than inactive women.
Conclusions
Modifiable lifestyle behaviors were related to recovery from MetS and/ decreased risk of the most frequent MetS constellations in midlife women.
