Association between maternal pre pregnancy and pre delivery overweight with overweight and obesity of middle school students:a case control study / 中国学校卫生

Objective@#To explore the association between maternal pre pregnancy and pre delivery overweight with overweight and obesity among offspring during adolescence in Guangzhou, and to provide evidence for child obesity prevention.@*Methods@#Based on the routine physical examination of primary and secondary school students in Guangzhou, random sampling was used to 6 middle schools and questionnaire survey was conducted among 3 384 students and their parents. Students with overweight and obesity were included in the case group, and the other students were included in the control group. Propensity Score Matching (PSM) was adopted to reduce selection bias. Logistic regression model and χ 2 test were used to analyze the data before and after PSM.@*Results@#The result of univariate analysis showed that there were statistically significant differences between overweight/obese group and the control group by gender, schooling stage (middle and high schools), picky eater, family history of obesity, family monthly income, delivery mode, high birthweight, and gestational weight gain before PSM( χ 2=42.38, 10.64, 14.47, 26.85, 10.58, 13.59 , 15.53, 20.64, P <0.05). After PSM, results showed that there were no statistically significant differences between overweight/obese group and the control group in middle and high schools, and mother delivery mode( P >0.05). Logistic regression analysis showed that the risk of overweight and obesity of maternal pre pregnancy on adolescent offspring was 1.54 times higher than control group (95% CI =1.01-2.36) before PSM, and the overweight and obesity of maternal predelivery also increased the risk of overweight and obesity of adolescent offspring( OR=2.35, 95%CI =1.67-3.31). After PSM, maternal overweight and obesity pre pregnancy ( OR=2.17, 95%CI =1.41-3.34) and maternal overweight and obesity pre delivery( OR=2.99, 95%CI =2.08-4.31) significantly increased the risk of overweight and obesity in adolescent offspring.@*Conclusion@#Maternal overweight and obesity pre pregnancy and pre delivery are associated with increased risk of overweight and obesity in adolescent offspring.

Observation on the Hemorheology in the Treatment of Primary Hypertension with Bloodletting Cupping plus Acupuncture / 上海针灸杂志

ObjectiveTo compare the clinical efficacies between bloodletting cupping plus acupuncture and acupuncture alone in treating hypertension.MethodSixty patients with primary hypertension were randomized into a treatment group and acontrol group, 30 cases in each group. The treatment group was intervened by bloodletting cupping plus acupuncture, while the controlgroup was by acupuncture. The clinical symptoms, blood pressure, and hemorheological parameters were observed before and after intervention.ResultThe clinical symptoms were improved in both groups after intervention, and the total effective rate was 76.7%in the treatment group versus 63.3% in the control group; the blood pressure dropped in both groups, and the differences were statistically significant between the two groups (P<0.05); the treatment group was superior to the control group in improving the whole blood viscosity and erythrocyte sedimentation rate(P<0.01).ConclusionBloodletting cupping is effective in treating primary hypertension; regarding the short-term therapeutic efficacy, bloodletting cupping plus acupuncture can produce a more significant effect than acupuncture alone in improving the blood pressure, whole blood viscosity, and erythrocyte sedimentation rate in primary hypertension patients.
