ABSTRACT
Objective To analyze the epidemiological characteristics of mumps in Guangxi from 2011 to 2019, and to provide a scientific basis for formulating effective prevention and control strategies. Methods Descriptive epidemiological method was used to analyze the incidence data of mumps in Guangxi from 2011 to 2019. Results From 2011 to 2019, a total of 146,132 cases of mumps were reported in Guangxi, with an average annual incidence rate of 34.23 /100 000. There were 88,919 male cases (60.85%) and 57,213 female cases (39.15%). The incidence rate decreased from 62.26/100 000 in 2011 to 16.46/100 000 in 2015, and increased from 18.60/100 000 in 2016 to 46.90/100 000 in 2019. There were seasonal variations in the incidence, with the incidence peaks occurring from April to July and from October to the following January. 85.39% of cases were under 15 years of age, and 76.82% of cases were among kindergarteners or school children. A total of 228 mumps outbreaks were reported during 2011-2019，including 5,347 cases, accounting for 3.66% of the total cases. The incidence rates of mumps in Nanning (56.09/100 000), Hechi (48.26/100 000), Liuzhou (46.77/100 000), Baise (46.34/100 000) and Fangchenggang (40.68/100,000) were relatively higher than other places. Conclusion The mumps incidence is on an upward trend in Guangxi since 2015-2019, occurring mainly in older children or students. It is suggested to adhere to the second dose of mumps containing vaccine for kindergarten and school children and strengthen the surveillance and outbreak control of mumps in schools.
ABSTRACT
Objective To study the differences in body composition and blood lipids between the pre-and post-menopausal women of Maonan ethnicity , and to explore the correlations between body fat content , fat distribution and blood lipids.Methods Totally 200 Maonan pre-and post-menopausal women were randomly selected from Huanjiang county in Guangxi.Body composition were measured by bioelectrical impedance analysis (BIA), and blood lipids were tested from blood samples .Results Compared with the pre-menopausal women , the visceral fat level (/area ) , waist-hip ratio (WHR), left (/right) lower limbs fat, total cholesterol (TC), triglyceride (TG) and low-density lipoprotein( LDL-C) in post-menopausal women were significantly higher ( P <0.01 ) , and the detection rate of hypercholesterolemia , mixed hyperlipidemia and dyslipidemia in postmenopausal group was also significantly higher ( P<0.01 ) .All the blood lipids were closely related to WHR and visceral fat content (P<0.05 or P<0.01).In addition, TG, high-density lipoprotein ( HDL-C) and LDL-C except TC were significantly correlated to %BF, BMI and subcutaneous fat content ( P<0.05 or P<0.01).Conclusion The accumulation of visceral and abdominal fat in Maonan postmenopausal women is significantly correlated to dyslipidemia .The results may provide references for making preventive program for the Maonan women .
