OBJECTIVE: To analyze the relationship between body fat mass and distribution and cardiovascular function in the adult females of Heilongjiang province. METHODS: Based on the statistic variable random sampling principal, we selected 1903 healthy adult females with ages of 18 - 70 years old in Heilongjiang province to conduct the study. The height, body weight, waist, chest measurement and waist-hip ratio (WHR) were measured. Body components quota including fat weight, lean weight, percentage of body fat (PBF) were taken respectively; systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), cardiac output (CO), cardiac index (CI), stroke volume (SV), stroke index (SI), left cardiac work (LCW) and systemic vascular resistance (SVR) were determined. RESULTS: The PBF and WHR increased with aging, and the PBF of those with ages of 18-, 30-, 40-, 50- and 60 - 70 year's old were (16.86 +/- 5.37)%, (18.43 +/- 4.89)%, (20.99 +/- 5.79)%, (23.47 +/- 5.74)% and (25.77 +/- 6.38)%, respectively (F = 154.46, P < 0.01); and the WHR were 0.77 +/- 0.05, 0.80 +/- 0.05, 0.83 +/- 0.05, 0.85 +/- 0.06 and 0.89 +/- 0.07, respectively (F = 229.84, P < 0.01). The HR, CO, CI, SBP, DBP and LCW were (75.45 +/- 0.35) bpm, (4.42 +/- 0.02) L/min, (2.78 +/- 0.01) L * min(-1) * m(-2), (114.94 +/- 0.40) mm Hg (1 mm Hg = 0.133 kPa), (64.90 +/- 0.28) mm Hg, (4.57 +/- 0.03) kg * m/m(2) respectively in normal PBF groups; whereas the HR, CO, CI, SBP, DBP and LCW in the PBF obesity groups were (77.42 +/- 0.88) bpm, (4.54 +/- 0.05) L/min, (2.88 +/- 0.03) L * min(-1) * m(-2), (120.55 +/- 1.00) mm Hg, (66.56 +/- 0.71) mm Hg and (4.86 +/- 0.07) kg * m/m(2), respectively, F values were 3.182, 9.173, 8.478, 13.497, 2.637, and 10.631, respectively (all P values < 0.05) after the adjustment of age, height and weight, PBF was positively correlated with HR, CO, CI, SI, SBP, DBP and LCW (r values were 0.06, 0.11, 0.10, 0.11 and 0.12, respectively, all P values < 0.05); WHR was positively correlated with CI, SI, SBP, DBP, LCW and SVR (r values were 0.14, 014, 0.19, 0.18, 0.10 and 0.12, respectively, all P values < 0.01) after the adjustment of age, height and weight. CONCLUSION: PBF augmentation and abdominal obesity in females can result in cardiac dysfunction such as cardiac overload, CO increasing and blood pressure rising.
