PURPOSE
This study investigated blood pressure and ventilation efficiency by cardiopulmonary exercise test (CPX) in different types of obesity aged 40-60 years.
MATERIAL AND METHODS
The inclusion criteria of this cross-sectional study were adults aged 40-60 years underwent health checks. CPX was measured according to the relevant standards. According to different body mass index (BMI), there were 3 groups, BMI<24 (kg/m), 24≤BMI<28 (kg/m) and BMI≥28 (kg/m). There were two groups in male, waist circumference≥90 (cm) and waist circumference<90 (cm). Similarly, there were two groups in female, waist circumference≥85 (cm) and waist circumference<85 (cm).
RESULTS
There were 543 individuals (64.6% male and 35.4% female) aged 40-60 years in this study. The resting blood pressure (BP) and peak BP have the significant differences in different BMI groups (p < 0.001) and male or female groups (p < 0.001). However, the resting DBP (77.70±9.45 vs 81.16±8.80, p < 0.001) and peak DBP (85.67±10.21 vs 89.03±9.94, p = 0.002) have the significant differences in different male waist circumference groups, and the resting BP (SBP 113.76±14.29 vs 121.86±15.54, p = 0.001, DBP 71.95±10.83 vs 77.27±11.42, p = 0.005) has the significant differences in different female waist circumference groups. Carbon dioxide Ventilation equivalent (VE/VCO) has the significant differences in different male waist circumference groups (26.84±3.10 vs 27.68±2.93, p = 0.009), but it has not the significant differences in different BMI groups and different female waist circumference groups. The oxygen pulse (VO/HR) is slightly higher in female group than male group (0.93±0.15 vs 0.89±0.15, p = 0.001). Breathing reserve has the statistical significance in BMI ≥28 group compared with the BMI <24 group (0.52±0.13 vs 0.46±0.17, ηp=0.021).
CONCLUSION
We found that the blood pressure and ventilation efficiency of CPX were different between the obesity and normal. This will provide a basis for accurate cardiopulmonary assessment of obesity.
目的
本研究通过心肺运动试验（CPX）调查40至60岁不同类型肥胖者的血压和通气效率。
材料与方法
本横断面研究的纳入标准为40至60岁接受健康检查的成年人。CPX根据相关标准进行测量。根据不同的体重指数（BMI），分为3组，BMI<24（kg/m²）、24≤BMI<28（kg/m²）和BMI≥28（kg/m²）。男性分为两组，腰围≥90（cm）和腰围<90（cm）。同样，女性分为两组，腰围≥85（cm）和腰围<85（cm）。
结果
本研究纳入了543名40至60岁的个体（男性占64.6%，女性占35.4%）。静息血压（BP）和峰值血压在不同BMI组（p<0.001）以及男性或女性组（p<0.001）中存在显著差异。然而，静息舒张压（77.70±9.45 vs 81.16±8.80，p<0.001）和峰值舒张压（85.67±10.21 vs 89.03±9.94，p = 0.002）在不同男性腰围组中存在显著差异，静息血压（收缩压113.76±14.29 vs 121.86±15.54，p = 0.001，舒张压71.95±10.83 vs 77.27±11.42，p = 0.005）在不同女性腰围组中存在显著差异。二氧化碳通气当量（VE/VCO）在不同男性腰围组中存在显著差异（26.84±3.10 vs 27.68±2.93，p = 0.009），但在不同BMI组和不同女性腰围组中无显著差异。女性组的氧脉搏（VO/HR）略高于男性组（0.93±0.15 vs 0.89±0.15，p = 0.001）。与BMI<24组相比，BMI≥28组的呼吸储备具有统计学意义（0.52±0.13 vs 0.46±0.17，ηp=0.021）。
结论
我们发现肥胖者与正常者在CPX的血压和通气效率方面存在差异。这将为肥胖者的准确心肺评估提供依据。
