Abstract： Objective:To evaluate the effect of lifestyle interventions on cardiovascular risk factors in overweight/obese individuals.Methods:A total of 148 overweight/obese subjects who had annual physical exam in the Health Management Center, the First Affiliated Hospital Zhejiang University School of Medicine from Dec 2017 to Dec 2020 were included. They were divided into the self-management group ( n=74) and the intervention group ( n=74). The intervention group was given a 6-month lifestyle intervention, while the self-management group received regular nutrition and physical activity education. Anthropometric and laboratory data was collected at baseline and after intervention in both groups. Effect of the intervention was evaluated. Results:The age of subjects in the intervention and self-management group was (42.5±7.5) and (40.1±9.6) years, respectively. After the intervention, weight, body mass index, waist/hip ratio, visceral fat area, systolic blood pressure, diastolic blood pressure, uric acid, homocystein, triglyceride, alanine aminotransferase andγ-glutamyl transferase of the intervention group [(75.6±12.7) kg, (26.72±3.04) kg/m 2, 0.92±0.05, (104.4±28.5) cm 2, (124.2±13.7) mmHg (1 mmHg=0.133 kPa), (77.8±10.1) mmHg, (353.6±84.8) μmol/L, 9.11(7.73, 10.00) μmol/L, 1.23(0.83, 1.91) mmol/L, 19.5(13.0, 29.5) U/L, 19.0(13.0, 30.5) U/L, respectively] were significantly lower than that of the baseline data [(81.1±12.5) kg, (28.64±2.82) kg/m 2, 0.95±0.04, (127.2±26.6) cm 2, (132.4±14.7) mmHg, (83.2±10.2) mmHg, (387.2±91.2) μmol/L, 10.25(8.30, 11.70) μmol/L, 1.78(1.40, 2.37) mmol/L, 28.0(18.0, 58.0) U/L, 36.0(23.0, 54.3) U/L, respectively] (all P<0.05); compared with the self-management group [(80.1±9.2) kg, 31.7% (28.5%, 38.4%), (119.5±32.6) cm 2, (133.5±15.9) mmHg, (82.6±12.2) mmHg, (4.93±0.86) mmol/L, 1.78(1.26, 2.97) mmol/L, respectively], the intervention group had decreased weight, body fat percent, visceral fat area, systolic blood pressure, diastolic blood pressure, total cholesterol, triglyceride [(75.6±12.7) kg, 30.0%(26.3%, 34.3%), (104.4±28.5) cm 2, (124.2±13.7) mmHg, (77.8±10.1) mmHg, (4.53±0.83) mmol/L, 1.23(0.83, 1.91) mmol/L, respectively], and increased high-density lipoprotein cholesterol [(1.09±0.24) vs (1.18±0.28) mmol/L] (all P<0.05). Conclusion:An intensive lifestyle intervention has a beneficial effect on cardiovascular risk factors in overweight/obese individuals.
