RESUMEN
ObjectiveTo investigate the association of lipid ratios with diabetes and pre-diabetes in residents aged 35-75 years in Changzhou City. MethodsA multistage whole-group random sampling method was used to survey permanent residents aged 35-75 years in Tianning and Wujin districts of Changzhou City， and the study data were obtained by questionnaires， physical examination and laboratory tests. The relationship between lipid ratios and diabetes and pre-diabetes was analyzed by dichotomous logistic regression method. ResultsThe prevalence of diabetes in the surveyed population in Changzhou was 18.69%， and the prevalence of pre-diabetes was 10.53%. In the total population， the risk of pre-diabetes was significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 68%， 93% and 38%， respectively； the risk of diabetes was also significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 105%， 149% and 78%， respectively. The risk of diabetes was also significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 105%， 149% and 78%， respectively. All three lipid ratios increased in women compared to men， leading to a stronger association with increased risk of diabetes and pre-diabetes. ConclusionLipid ratios TC/HDL-C， TG/HDL-C， and LDL-C/HDL-C were correlated with the risk of diabetes and pre-diabetes in people aged 35-75 years， with TG/HDL-C having the strongest association with diabetes and pre-diabetes， and is expected to be a key predictor for assessing the development of diabetes.
RESUMEN
Objective:To investigate the correlation and dose-response relationship of pulse pressure and pulse pressure index with metabolic syndrome in the elderly population.Methods:This was a cross-sectional study.A total of 114 212 subjects aged 65 years and over in Wujin District receiving health examination in 2019 were enrolled, including 40 388(35.4%)patients with metabolic syndrome.The survey contents included a questionnaire, physical examination and laboratory tests.Logistic regression and restricted cubic splines were used to analyze the correlation and dose-response relationship of pulse pressure and pulse pressure index with metabolic syndrome.Results:With increases in pulse pressure levels and pulse pressure index, the prevalence of metabolic syndrome and its components increased accordingly( P<0.01). After adjusting for confounding factors, the ORvalue of metabolic syndrome gradually increased along with increases in pulse pressure and pulse pressure index.Compared with the first quartile, pulse pressure and pulse pressure index in the second, third and fourth quartiles were correlated with metabolic syndrome(pulse pressure: OR=1.52, 95% CI: 1.47~1.58, OR=1.89, 95% CI: 1.82~1.96 and OR=2.15, 95% CI: 2.07~2.23, respectively; pulse pressure index: OR=1.22, 95% CI: 1.18~1.26, OR=1.36, 95% CI: 1.31~1.41 and OR=1.47, 95% CI: 1.42~1.53, respectively). Restricted cubic spline analysis showed that pulse pressure and pulse pressure index had non-linear dose-response relationships with metabolic syndrome( χ2=309.23 and 57.14, P<0.01). Conclusions:Pulse pressure and pulse pressure index are correlated and show non-linear dose-response relationships with metabolic syndrome and its components in the elderly.
RESUMEN
Objective To evaluate the effect and cost-benefit of influenza vaccination for patients with chronic diseases in Wujin district of Changzhou City. Methods An epidemiological quasi-experiment was employed in this study. A total of 441 patients with chronic diseases were recruited as the vaccine group and inoculated with trivalent influenza virus vaccine, while 467 patients with chronic diseases matched with the age, gender and health status of the vaccine group were selected as the control group for both baseline and follow-up investigations. Results A total of 431 subjects in the vaccine group and 460 subjects in the control group completed baseline and 1-year follow-up investigations. The incidence of influenza-like illness was 7.42% (32/431) and 14.13% (65/460) in the vaccine group and the control group, respectively, with a statistically significant difference (χ2=9.634, P=0.002). The protective rate was 47.46%, and the effect index was 1.90. The incidence of common cold was 16.94% (73/431) and 25.43% (117/460), respectively, and the difference was statistically significant (χ2=9.077, P=0.003), with a protective rate of 33.41%, and an effect index of 1.50. The incidence of chronic disease was 5.57% (24/431) and 9.35% (43/460), respectively. The difference was statistically significant (χ2=4.043, P=0.044), with a protective rate of 40.43% and an effect index of 1.68. The per capita benefit of inoculation was 675.86 yuan, and the benefit-cost ratio was 10.09:1. Conclusion Influenza vaccination for patients with chronic diseases effectively prevented the occurrence of influenza-like illness and reduced the incidence of related chronic diseases.
