Objective To understand the prevalence of chronic kidney disease (CKD) in the elderly in xuzhou area and the main related factors, and to provide a theoretical basis for the prevention and treatment of CKD. Methods Xuzhou gulou, mountain springs, deals for the city select venture, peixian county rural countryside, deals with the community (village) as unit, adopt the method of stratified cluster sampling, a random sample of urban and rural community people aged 60 to 79, and residents living longer than six months as investigation object, obtain 482 valid data, chronic kidney disease (CKD) sampling investigation, All subjects underwent conventional questionnaires, including gender, age, occupation, chronic disease history, family history, etc. Laboratory tests included, UA, SCr, FBG, 2H PBG, TG and TC levels. EGFR was calculated based on SCr, and logistic regression was used to analyze the independent risk factors for CKD in the elderly in community. Results Among 482 elderly patients, 259 were males and 223 were females, with an average age of (45.73±6.14) years. 63 patients with CKD were diagnosed, with a prevalence rate of 13.07%. The prevalence of chronic diseases was 20.33%(98/482) for hypertension, 15.15%(73/482) for hyperuricemia, 11.00%(53/482) for overweight or obesity, 8.71%(42/482) for hyperlipidemia and 6.430%(31/482) for diabetes. The prevalence of CKD in 70-79 year olds was significantly higher than that in 60-69 year olds (χ²=6.621 , P<0.05). There were statistically significant differences in age, hypertension, diabetes and hyperuricemia between 2 groups (P<0.05). Logistic regression analysis showed that advanced age, hypertension, diabetes and hyperuricemia were independent risk factors for CKD in elderly population in Xuzhou area (P<0.05). Conclusion The prevalence of CKD in the elderly in Xuzhou community is high, and the main risk factors are advanced age, diabetes, hypertension and hyperuricemia. It is necessary to actively carry out early screening of CKD and take effective preventive measures to effectively delay the development of CKD and prevent the occurrence of end-stage renal disease.

Objective To investigate the epidemiological characteristics of chronic obstructive pulmonary disease (COPD) in patients aged 65 years and above in Liaoning Province. Methods Between January 2019 and December 2020, a cluster random sampling method was used to investigate residents ≥ 65 years old in Sujiatun Community, Shenyang City, Liaoning Province. The pulmonary function tests of the selected residents were conducted. Questionnaire surveys were carried out and 5738 questionnaires with complete data were analyzed. Results A total of 620 COPD cases were diagnosed among 5738 people investigated in the present study, with a total prevalence rate of 10.81%, of which the prevalence rate in men was 12.58% (371/2950), and the prevalence rate in women was 8.93% (249/2950). According to the GOLD classification of lung function, 620 patients can be divided into 186 (30.49%) cases of grade I, 266 (43.61%) grade II, 118 (19.34%) grade III, and 50 (8.20%) cases of grade IV. The problem with lung function in males was more serious than that in females, which increased gradually with age (P<0.05). Multivariate logistic regression analysis showed that gender, age, BMI, smoking, childhood respiratory history, family history, occupational exposure, indoor oil fume and use of polluted fuel for heating were independent risk factors affecting the onset of COPD (P<0.05). Conclusion The prevalence of COPD in patients aged 65 years old and above in Liaoning is relatively high. Gender, age, BMI, smoking, childhood respiratory history, family history, occupational exposure, indoor oil fume, and use of polluted fuel for heating are related to the onset of COPD. Clinical attention should be paid to early screening and prevention of COPD in those populations to reduce the prevalence of COPD..

Objective This article takes a cosmetics factory in Yichang City as an example, uses a variety of methodologies to explore methods of health impact assessment and provides methodological references for future health evaluation of related public policies. Methods By analyzing the environmental assessment report of the cosmetic renovation project, an indicator system was established and expert consultation meetings were conducted to score the impact of the corresponding indicators on health. The impact of the renovation project of the factory on the factory workers, surrounding residents and the sustainable development of the environment was analyzed by means of the Kaiser model with the risk matrix and the Borda value. Results The risk values of the five influencing factors of industrial wastewater, domestic wastewater, industrial waste gas, industrial waste and noise were 5.11%, 5.43%, 10.6%, 6.71% and 7.02% respectively. All the influencing factors were in the green zone of the risk matrix. The Borda values of the five influencing factors of industrial waste water, domestic waste water, industrial waste gas, industrial waste residue and noise were 4, 5, 10, 7 and 5 respectively. Conclusion The multiple methodologies adopted in the factory renovation project are feasible, and can provide new ideas for the health impact assessment of public policies in the future.
