Objective To compare the effects of cardiopulmonary resuscitation by bending and pressing the lower extremities (BPLE-CPR) with standard cardiopulmonary resuscitation (S-CPR). Methods A multicenter prospective nonrandomized controlled study was performed. Patients with cardiac arrest (CA) treated in the emergency departments and intensive care units (ICU) of seven hospitals in Eastern China from January 2013 to February 2017 were enrolled. BPLE-CPR or S-CPR was used for resuscitation according to the patient's condition. Data registration was completed in Utstein style. The primary outcome was recovery of spontaneous circulation (ROSC) rate, and the secondary outcome included survival rate at discharge, the resuscitation time of ROSE patients, blood pressures during resuscitation, the survival rates within 24 hours and beyond 24 hours, and the cerebral performance categories (CPC) of discharged patients. Results A total of 279 patients completed data registration, including 142 in the BPLE-CPR group and 137 in the S-CPR group. ROSC rate, survival rates over 24 hours and at discharge in BPLE-CPR group were significantly higher than those in S-CPR group [ROSC rate: 63.4% (90/142) vs. 29.2% (40/137), survival rate over 24 hours: 56.7% (51/90) vs. 45.0% (18/40), survival rate at discharge: 43.0% (61/142) vs. 20.4% (28/137), all P < 0.01]. The CPR duration of ROSC patients in BPLE-CPR group was significantly shorter than that in S-CPR group [minute:10 (5, 15) vs. 20 (11, 30), P < 0.01], while systolic blood pressure during CPR was significantly higher than that in S-CPR group [mmHg (1 mmHg = 0.133 kPa): 92.0 (80.0, 110.0) vs. 73.5 (65.5, 80.0), P < 0.01]. In survival discharged patients, the proportion of CPC 1 patients in BPLE-CPR group was significantly higher than that in S-CPR group [24.6% (15/61) vs. 10.7% (3/28), P < 0.01]. Conclusion BPLE-CPR is superior to S-CPR in terms of ROSC rate and discharge survival rate. In addition, the BPLE-CPR procedure is simple and easy to expand in public.

Objective: To investigate the prevalence and related factors of obesity and central obesity among 35-75 year-old population in Jiangsu Province. Methods: During 2015-2017,83 530 eligible subjects aged 35-75 years from six study sites of Jiangsu Province were interviewed and examined. The data of demography,lifestyles,disease history,height,weight and waistline were collected. Logistic regression analysis was conducted for the influencing factors for obesity and central obesity. Results: A total of 83 393 residents completed the study,with a response rate of 99.84%. The prevalence of overweight,obesity and central obesity was 43.35%（standardized rate：35.90%）,20.02%（19.48%）and 59.93%（57.03%）. The results of multivariate logistic regression analysis showed that females（OR=0.822,95%CI：0.786-0.859;OR=0.900,95%CI：0.851-0.952;OR=1.130,95%CI：1.083-1.179）,45-75 years old（OR：1.120-1.731,95%CI：1.102-1.881）,graduating from high school or above（OR：0.767-0.902,95%CI：0.721-0.943）,living in urban areas（OR：1.530-2.077,95%CI：1.284-3.007）,smoking（OR：0.724-0.855,95%CI：0.678-0.898）,drinking （OR：1.125-1.179,95%CI：1.076-1.235）,hypertension（OR：1.884-3.461,95%CI：1.821-3.613）,diabetes（OR：1.363-1.758,95%CI：1.305-1.851）, dyslipidemia（OR：1.478-1.870,95%CI：1.429-1.851）were associated with overweight,obesity and central obesity. Conclusion The standardized prevalence rates of overweight,obesity and central obesity among 35-75 year-old population in Jiangsu Province are 35.90%,19.48% and 57.03%,respectively. Gender,age,education,residence,smoking,drinking,hypertension,diabetes and dyslipidemia are related factors.
