Correlation between hypovolaemia and risk factors of cardiovascular disease of adult women / 中国综合临床

ABSTRACT

Objective To discuss the major cardiovascular disease(CVD) risk factors and volume load of women.Methods A cross-sectional study was conducted on adult women who came to our hospital for health examination.The clinical data included age, past medical history, smoking history, drinking history, body measurements (height, body weight, blood pressure, etc.), and blood serum creatinine, hemoglobin, blood glucose, blood lipid and other biochemical indicators were detected.Using the human body composition analyzer, the extracellular fluid (ECW), intracellular fluid (ICW), total water(TBW), and ECW/TBW ratio (E/T) were used to evaluate the capacity of the cells.Total body water(TBWwatson) was Calculated according to Watson formula.The clustering of four major CVD risk factors (defined as two or more of the following hypertension, diabetes, dyslipidemia and overweight) and their association with volume load were investigated.Volume load was evaluated by bioelectrical impedance analysis.Hypovolaemia was defined as extracellular water/total body water (ECW/TBW) at and under the 10 percentile for the normal population.Logistic regression model was use to explore the relationship between capacity status and risk factors of CVD.Results A total of 2 433 women (mean age (37.4±7.3) years old) were enrolled in the study, 14.7％ of them had clustering of CVD risk factors.Hypovolaemia in clustering group was statistically higher than either in the single or in the none risk factor group, which was 18.2％, 11.9％, 6.7％, respectively (x2 =45.4, P＜0.001).After adjusted for potential confounders (including age, hemoglobin, serum uric acid, estimating glomerular filtration rate (eGFR), hypovolaemia was associated with clustering of CVD risk factors, with an OR of 2.76 (95％ CI 1.93-3.95).Conclusion Hypovolaemia is associated with clustering of major CVD risk factors in women, which further confirms the importance of modifying lifestyle to reduce the burden of CVD.
