ABSTRACT
@#Abstract: Objective This study aims to explore the prevalence and risk factors of metabolic syndrome (MS) among the adults in Hainan Province, and to provide scientific basis for MS prevention and control. Methods A multi-stage cluster random sampling method was applied to select 3 690 permanent residents aged 18 years and above in Hainan Province. The survey was conducted by trained investigators using household appointments and centralized surveys. A questionnaire survey, physical measurement, and laboratory examination were conducted after the collection of blood samples. The processed samples were then tested by a quality-controlled laboratory. Finally, we analysed the prevalence of metabolic syndrome (MS) and its relationship with population characteristics and health-related behaviors. Results The crude prevalence of MS in the population aged 18 and above in Hainan province was 19.46% and the standardized prevalence was 13.21%, with a higher rate in urban areas (22.21%) than in rural areas (18.13%). The prevalence of MS increased with age (P<0.001), and there were significant differences in MS prevalence among different marital and occupational statuses (P<0.01). Logistic regression results indicated that the age groups of 40-<50 years (OR=2.986, 95%CI:1.355-6.580), 50-<60 years (OR=3.739, 95%CI: 1.715-8.151), 60-<70 years (OR=3.890, 95%CI: 1.769-8.556), 70 years and above (OR=3.927, 95%CI: 1.758-8.771), technical, transportation and production personnel (OR=1.579, 95%CI: 1.033-2.412), retired (OR=1.788, 95%CI: 1.415-2.259), unemployed (OR=1.503, 95%CI: 1.044-2.165), smoking cessation (OR=1.582, 95%CI: 1.162-2.154), insufficient intake of fruits and vegetables (OR=1.196, 95%CI: 1.005-1.422), and insufficient physical activity (OR=1.437, 95%CI: 1.155-1.787) were all associated with the prevalence of MS. Among the investigated subjects, 30.22% of them had one abnormal component, with hyperglycemia being the highest (54.44%); 24.25% of them had two abnormal components, with "hyperglycemia + hypertension" being the highest (33.30%); and 19.46% had three or more components, with "overweight/obesity + hyperglycemia + hypertension" being the highest (24.79%). Conclusions The prevalence of MS in Hainan Province is on the rise, and effective lifestyle intervention measures are needed to reduce the risk of MS.
ABSTRACT
@#Abstract: Objective To understand the general situation of death causes of permanent residents in Hainan Province from 2014 to 2020, analyze the causes of death, and provide scientific basis for the formulation of policies related to healthy Hainan. Methods The Hainan Provincial Population Death Information Registration and Management System was used to report data, and the death information of permanent residents in Hainan Province from 2014 to 2020 was obtained. Excel 2010 and SPSS 26.0 software were applied to perform statistical analysis related to the indicators including crude mortality rate, standardized mortality rate, ranking of causes of death, and composition ratio; the standardized mortality rate was calculated based on the data of the 2010 National Census Data. Results From 2014 to 2020, the average annual resident population of Hainan Province was 9 175 300, and average annual resident population at each of the eight monitoringp oints is 297 100， anaverage of 83 878 cumulative deaths were reported, the annual total mortality rate was 504.09/100 000, the standard mortality rate was 618.69/100 000. The standardized mortality rates of male and female were 806.18/100 000 and 444.36/100 000 respectively (P<0.01). The mortality rate of all age groups showed that the crude mortality rate of 0~<1 years old group showed a decreasing trend with the passage of time, and the crude mortality rate was significantly higher than that of other age groups. From the age of 20, with the increase of age, the overall crude mortality rate of residents keeps increasing. The crude death rate increases rapidly after the age of 65, and peaks especially after the age of 85. The leading causes of death were circulatory diseases, tumors and respiratory diseases. From 2014 to 2020, the mortality rate of circulatory diseases and tumors, the two main causes of death, was more than 100/100 000. Conclusion Chronic non-communicable diseases are still the first cause of death among permanent residents in Hainan Province. Targeted intervention and treatment of chronic non-communicable diseases is beneficial to reduce their mortality.
ABSTRACT
Objective To improve the design of the fluid supplementation system of Johnson & Johnson automatic blood typing and cross matching instrument to optimize its working flow.Methods Two polyethylene funnels were placed at the cabinet door to execute drainage,which had the height being 14.6 cm,diameter of the wide mouth being 15 cm,protective lip made of hardboard and volume being 700 ml.Each funnel was connected with a 21-mm-diameter drainage tube whose end was put into a flask full of 0.9％ saline or distilled water respectively.Results The velocity was enhanced efficiently for fluid supplementationn,surface pollution due to liquid splash was avoided,and working comfort and efficiency were increased greatly.Conclusion The improved fluid supplementation system gains advantages in low cost,no pollution and convenience,and thus is worthy promoting practically.
