RESUMEN
Objective:To analyze the correlation between the body composition and cardiorespiratory fitness (CRF) decline in physical examination population of different genders.Methods:Clinical data of the cardiopulmonary exercise testing (CPET) and body composition analysis of 439 people who received physical examination in the Medical Examination Center of Peking University Third Hospital from May 2021 to September 2021 were retrospectively analyzed. The general data, physical examination, biochemical parameters, body composition and CPET results were collected. The subjects were divided into normal group and decline group according to the percentage of peak oxygen uptake (VO 2peak) levels ≥ 85% or<85%. Multivariate logistic regression was applied to investigate the influencing factors of CRF decline in subjects of different genders. Results:Among men, total cholesterol and triglyceride in the decline group were significantly higher than those in the normal group [(5.097±0.890) vs (4.865±0.856) mmol/L, (1.778±1.200) vs (1.485±0.709) mmol/L], and the blood homocysteine (Hcy) and skeletal muscle index were significantly lower than those in the normal group [13.00 (11.30, 15.90) vs 13.80 (12.05, 17.10) μmol/L, (7.89±0.65) vs (8.08±0.64) kg/m 2] (all P<0.05). Among women, skeletal muscle index in the decline group was significantly lower than that in the normal group [(6.21±0.52) vs (6.53±0.56)kg/m 2], and percent body fat was significantly higher than that in the normal group [(32.83±4.92)% vs (31.21±4.55)%] (all P<0.05). The elevation of triglyceride level ( OR=1.487, 95% CI: 1.042-2.121) and visceral fat area ( OR=1.032, 95% CI: 1.014-1.051) were positively correlated with the decline of CRF in man, the decrease of skeletal muscle index ( OR=0.215, 95% CI: 0.106-0.435) and the increase of percent body fat ( OR=1.149, 95% CI: 1.060-1.245) were positively correlated with the decrease of CRF in women (all P<0.05). Conclusions:There is a correlation between body composition and CRF decline in physical examination population of different genders. Men should control visceral fat more effectively, and women should pay attention to increase muscle mass while reducing body fat, in order to improve CRF.
RESUMEN
Objective:To analyze the core elements′ index design of physical examination reports and pilot data.Methods:We searched and analyzed the core element indexes of the physical examination report in databases such as CNKI and Wanfang through the literature analysis method, forming the initial core element indicator set. Special working meetings were organized to discuss revisions and improvements. The core elements′ index set was formed using a mixed research method combined with the quantitative analysis results of pilot data and expert opinions. Six hundred and thirteen cases from five hospitals were included in this study, including Anzhen Hospital, Peking University Third Hospital, Beijing Physical Examination Center, Beijing Tongren Hospital, China-Japan friendship hospital.Results:The subjects were (49.5±17.6) years old, including 302 males (49.3%) and 311 females (50.7%). The physical examination conclusion indicates that the number of health problems is between five and eight, with no significant difference between men and women. The health history data analysis of different sexes showed that hypertension in men was significantly higher than in women (17.9% vs. 10.6%, P=0.010). The lifestyle and eating habits survey showed that men had significantly higher incidences of smoking and drinking than women (24.8% vs. 2.2%, P?0.001; 9.9% vs. 1.3%, P?0.001). The exercise habits and sleep survey showed that the proportion of men who did not exercise was lower than that of women (13.2% vs. 22.8%, P=0.022). There was no statistically significant difference in sleep duration between the sexes. Conclusions:The core elements of health examination reports can standardize the collection of physical examination data and improve its sharing and application. This can allow the reports to better assist the decisions based upon physical examination report data.
RESUMEN
Objective:To investigate the correlation between early renal impairment markers in urine and elevated serum homocysteine.Methods:Clinical data of serum homocysteine (Hcy) and early renal injury markers in urine of the health examination population from the Physical Examination Center of Peking University Third Hospital from January 2019 to May 2020 were retrospectively analyzed (1133 cases). The previous medical history, age, sex, blood pressure, body mass index (BMI) of the subjects were collected. Early urine kidney injury markers, including urine microalbumin (U-mALB), urinary N-acetyl-β-D-glucosaminidase (NAG), urinary albumin to creatinine ratio (UACR), and serum renal function, liver function, blood lipid, myocardial enzyme and glycosylated hemoglobin (HbA 1C), etc. were also collected. Those with incomplete previous history, general information, biochemical indexes and decreased estimated glomerular filtration rate (eGFR) were excluded, and 969 cases were included. The included subjects were divided into the normal group (?15 μmol/L) and the elevated group (≥15 μmol/L) according to Hcy levels, the indexes with significant difference between the two groups were included as independent variables, and the multivariate logistic regression was used to explore the influence factors of Hcy elevation. Results:The male ratio, the incidence of increased U-mALB, NAG and UACR were significantly higher in the elevated group than those in the normal Hcy group (93.4% vs 50.6%, 16.4% vs 8.0%, 23.0% vs 14.0%, 13.9% vs 7.9%) (all P<0.05). Systolic blood pressure, diastolic blood pressure, serum uric acid, calcium, alanine aminotransferase (ALT) and lactate dehydrogenase in the elevated group were higher than those in the normal group [(127.5±15.4) vs (121.9±16.2) mmHg (1 mmHg=0.133 kPa), (78.6±9.3) vs (76.0±11.0) mmHg, (385.9±86.0) vs (335.7±88.2) μmol/L, (2.392±0.086) vs (2.366±0.092) mmol/L, (27.8±21.0) vs (23.8±20.2) U/L, (198.3±28.4) vs (192.2±31.2) U/L] (all P<0.05), while high density lipoprotein cholesterol (HDL-C), serum phosphorus were lower than those in the normal group [(1.21±0.25) vs (1.31±0.30) mmol/L, (1.107±0.154) vs (1.158±0.159) mmol/L] (all P<0.05). The increased systolic blood pressure, male, uric acid, U-mALB, NAG were independent correlative factors of Hcy elevation. Conclusion:The increase of Hcy is independently correlated with urine U-mALB and NAG, which suggests that the level of Hcy should be detected as soon as possible in patients with elevated early renal injury markers.
