ABSTRACT
Objective:To investigate the prevalence of positive hepatitis C virus (HCV) antibody, HCV RNA and genotype distribution of HCV in high-risk populations in Pudong New Area, Shanghai City, so that to provide evidence for making "hepatitis C micro elimination" strategies in Shanghai area.Methods:A survey with proportional sampling method was conducted among the high-risk populations, including people who inject drugs (PWID), voluntarily or compulsorily accepted drug detoxification or methadone treatment, human immunodeficiency virus voluntary counseling and testing (HIV VCT) outpatients, sexually transmitted disease (STD) outpatients, and commercial sex workers, who participated in the routine physical examination activities held by the community health service centers and public hospitals of Pudong New Area from July 2021 to November 2022. The residual plasma samples were collected from medical examinations. HCV antibody was tested in all samples. HCV RNA and HCV genotype were tested in samples with positive HCV antibody results.Results:A total of 1 000 HCV high-risk people were screened, including 453 PWID, 166 human immunodeficiency virus (HIV) infectors, 245 STD outpatients, and 136 commercial sex workers. The positive rates of HCV antibody in the four categories of personnel were 21.85%(99/453), 1.81%(3/166), 1.22%(3/245) and 0(0/136), respectively. The positive rate of HCV RNA was 42.68%(35/82) among HCV antibody positive people in high-risk populations. As much as 74.29%(26/35) of HCV RNA positive people had junior high school education or less, and 77.14%(27/35) of them were not married. Among the 12 samples tested for HCV genotype, five were genotype 3, five were genotype 6, and two were subtype 1b.Conclusions:PWID is the main high-risk HCV infection population, who should be the target of the following "hepatitis C micro elimination" strategies. The proportions of genotype 3 and genotype 6 are high in the high-risk HCV infection populations, and the pan-genotype direct-acting antiviral agent treatment may be more suitable in this situation. HCV infected persons in high-risk groups have low education level and marriage rate, which indicates that education and care in community are needed.
ABSTRACT
Objective:To investigate the knowledge and compliance status of prevention and control of brucellosis among high-risk populations in counties and districts with high incidence of brucellosis in Xinjiang Uygur Autonomous Region (Xinjiang for brief), and to provide scientific basis for prevention and control of brucellosis and health education for high-risk populations.Methods:Huocheng County, a high incidence county of brucellosis in Xinjiang, was selected as the survey site. Three to six townships were selected, and two to three administrative villages were selected from each township as the survey villages. People over 18 years old and engaged in livestock breeding such as cattle and sheep breeders, livestock product processors, veterinarians and medical personnel were selected as the survey subjects. Face-to-face surveys were conducted by professional trained investigators in autumn and winter (December 2019 to January 2020) and spring and summer (April to July 2020). The survey included general demographic information, awareness of brucellosis prevention and control knowledge and the use of protective equipment.Results:A total of 600 people were surveyed, and 597 people completed the questionnaire, with an effective response rate of 99.50% (597/600). The overall awareness rate of brucellosis prevention and control knowledge was 68.23% (10 184/14 925), among which the awareness rate of clinical symptoms of human infection with brucellosis was high, at 73.53% (3 073/4 179). There were statistically significant differences in the awareness rate of main source of infection, main transmission route and clinical symptoms of human infection with brucellosis among people of different gender, age, nationality, education level and occupation ( P < 0.05). Among them, the awareness rate of clinical symptoms of human infection with brucellosis among veterinarians and medical personnel was 85.38% (514/602). The utilization rate of protective equipment such as rubber shoes and work clothes was high, which was 63.48% (379/597) and 60.97% (364/597), respectively. There were statistically significant differences in the utilization rate of protective equipment among different nationality, education level and occupation ( P < 0.05). Among them, The utilization rate of work clothes was the highest among people with college education or above, veterinarians and medical personnel, which was 82.61% (57/69) and 93.02% (80/86), respectively. Conclusions:The overall awareness rate of brucellosis prevention and control knowledge in high-risk groups in Huocheng County of Xinjiang is low, especially among high-risk groups such as those who are illiterate or have little literacy, and farmers, the awareness rate is low and the awareness of prevention and control is weak. There is a risk of brucellosis infection. It is necessary to further strengthen the education of brucellosis prevention and control knowledge among these groups.

ABSTRACT
Hepatitis E virus （HEV） infection is one of the most common causes of acute viral hepatitis. Most patients with HEV infection are asymptomatic and the virus can be spontaneously eliminated. Pregnant women， the elderly， immunocompromised populations， patients with chronic liver disease， and individuals in close contact with HEV-infected animals are at a high risk for HEV infection. The recombinant hepatitis E vaccine HEV 239 is the only approved hepatitis E vaccine， with both short- and long-term protective efficacy. This vaccine has a favorable safety profile with few adverse events， and the high-risk populations should be given the priority to receive such vaccination. Immunocompromised individuals may develop chronic HEV infection. Ribavirin and interferon are currently the most commonly used antiviral drugs for the treatment of HEV infection； however， it still needs to develop safe and effective novel antiviral drugs for patients with contraindications to ribavirin or interferon or those who have no response to such therapy.
ABSTRACT
Objective@#To investigate the proportion of achieving the blood lipid control target and its influencing factors among residents at a high risk of atherosclerotic cardiovascular disease (ASCVD), so as to provide insights into management of blood lipid among residents at a high risk of ASCVD.@*Methods@#Residents at a high risk of ASCVD and at ages of 35 to 70 years were sampled using a multi-stage cluster sampling method from 6 counties (districts) in Shaoxing City from May to July 2021. The residents' demographics, smoking, alcohol consumption and medical history of chronic diseases were collected using questionnaires, the height, weight, waist circumference (WC) and blood pressure were measured, and the total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and fasting blood glucose were detected. The proportion of blood lipids achieving the control target was analyzed, and factors affecting the proportion of blood lipids achieving the control target were identified using a multivariable logistic regression model.@*Results@#A total of 1 695 individuals at a high risk of ASCVD were enrolled, including 940 men (55.46%) and 755 women (44.54%), with a mean age of (62.56±6.08) years. There were 285 participants that achieved the target of blood lipid control (16.81%). Multivariable logistic regression analysis identified gender (male, OR=1.962, 95%CI: 1.396-2.758), age (OR=1.037, 95%CI: 1.013-1.061), WC (OR=0.979, 95%CI: 0.964-0.995), diastolic blood pressure (OR=0.981, 95%CI: 0.967-0.994), smoking (OR=1.485, 95%CI: 1.034-2.133), alcohol consumption (OR=0.684, 95%CI: 0.498-0.941), hypertension (OR=1.428, 95%CI: 1.006-2.207), administration of hypoglycemic drugs (OR=2.326, 95%CI: 1.720-3.144) as factors affecting the achievement of the target for blood lipid control among residents at a high risk of ASCVD. @*Conclusions @#Individuals at a high risk of ASCVD with higher WC, higher diastolic blood pressure and alcohol consumption are less likely to achieve the target for blood lipid control, while male individuals with older age, hypertension and administration of hypogcemic drugs are more likely to achieve the target for blood lipid control.
ABSTRACT
ObjectiveA high-risk group of diabetes in a community in Shanghai was followed up for 2 years. The level of blood glucose control was monitored， the incidence and risk factors of the high-risk group were analyzed， and the incidence and risk factors distribution in the community were studied. The results will provide a basis for the community to formulate strategies for early prevention and treatment of diabetes in Shanghai. MethodsA total of 580 subjects were collected， according to the criteria of high-risk groups of diabetes. Among them， 77 people whose blood glucose had reached the diagnostic criteria for diabetes entered the patient group， and the rest 503 people entered the high-risk group. Corresponding intervention methods such as outpatient follow-up and health education were given， and blood glucose monitoring was repeated at the 12th month and 24th month after enrollment. Blood glucose control， new-onset diabetes and the effect of intervention were analyzed. ResultsThe patients’ venous fasting blood glucose level at the 12th and 24th month was significantly lower than that at the baseline survey， and there was no significant change in body mass index （BMI） and waist circumference. Subjects in patient group were older and had a higher proportion of a history of impaired glycemic regulation， family history of diabetes， hypertension， and hyperlipidemia than those in high-risk group. In the high-risk group of 503 cases， 74 （14.7%） were new-onset diabetics during the follow-up period， A higher proportion of new-onset diabetics were male， BMI， a combined history of impaired glucose regulation and gestational diabetes history of gestational diabetes mellitus （women only） was a contributing factor to the onset of diabetes. ConclusionHigh-risk groups are more susceptible to diabetes； patients in the diabetes group have better control of fasting blood glucose levels during the 2-year follow-up period， and outpatient follow-up combined with comprehensive interventions helps diabetic patients to control blood glucose.
ABSTRACT
Objective To screen for malignant tumors and high-risk factors in rural residents over 60 years old， so as to prevent and control the occurrence and development of tumors in the future. Methods The survey was conducted with reference to part of the questionnaire in the "Urban Cancer Early Diagnosis and Treatment Project and Evaluation of High-risk Populations". Clinical examinations included serum tumor marker detection， CT screening for lung cancer， occult blood （+） plus colonoscopy screening for colorectal cancer， and mammography screening. Individuals who were positive in the abovementioned clinical tests were defined as high-risk subjects. Results A total of 271 high-risk subjects （1.91%） were screened out of 14 161. Among the high-risk subjects， 71 cases of malignant tumors （26.19%） were found， with an incidence rate of 501.38 per 105. The top five tumors （63.38% of all diagnosed） were mainly concentrated in lung， upper digestive tract， blood system， urinary system， and rectum-colon. The proportion of malignant tumors detected by positive indicators was 61.54% of blood； 46.15% of carcinoembryonic antigen and carbohydrate antigen 125； 23.08% of alpha-fetoprotein； 16.66% of lung CT； and 3.09% of prostate PSA. The positive indicators in the high-risk subjects were mainly for the tumors in the prostate， lungs， liver， and CEA/CA125. The subjects with positive test indicators had lower average annual income in the last 5 years than the normal subject group （χ2=3.380， P=0.040）. The subjects with positive test indicators had higher proportion in family history of tumors than the normal group （χ2=2.596， P=0.046）. People in thehigh-risk group had a higher proportion than the normal group in suffering from hypertension， liver disease， gastrointestinal disease， respiratory system disease， and surgical treatment. Patients with high-risk tumors were found to have higher proportion than the normal group in showing pre-tumor clinical symptoms in the last 1 year. Study of the tumor-related risk factors found that the high-risk group had a higher proportion of high-fat/high-cholesterol diet， alcohol drinking， passive smoking， and personality depression. Conclusion High tumor risk factors have been identified in this population. It is necessary to strengthen the corresponding intervention and follow-up treatment of precancerous diseases in the future. We recommend the government to conduct tumor screening among high-risk groups to improve cost-effectiveness.
ABSTRACT
Objective:To explore the application effect of the intelligent interactive health education model in the health management of the smokers with high-risk of chronic obstructive pulmonary disease (COPD).Methods:From September 2019 to January 2020, 72 smokers with high-risk of COPD were recruited from Health Management Center, the First Affiliated Hospital of Nanjing Medical Universit y. The subjects were randomly divided into traditional group (35 cases) and intelligent group (37 cases) according to the intervention model. The traditional group used the method of mailing health education materials, while the intelligent group sent health education materials with the help of mobile intelligent platform for interactive feedback and intervention. After 12 weeks of intervention, the subjects′ nicotine dependence, international physical activity, population satisfaction, time consumption for follow-up and other indicators were compared. Results:After the intervention, the score of nicotine dependence in the intelligent group was lower than that in the traditional group [(1.86±1.48) vs (3.77±1.66), P<0.05], the number of smoking cessation cases was more than that in the traditional group (11 vs 1, P<0.05), the number of cases with significant improvement in the score of international physical strength scale was significantly improved than that in the traditional group (15 vs 0, P<0.01), and the satisfaction was higher than that in the traditional group (97.30% vs 42.85%, P<0.01), and the time consumption was less than that in the traditional group [(18.03±2.96) vs (25.14±2.64) min, P<0.01]. Conclusion:The intelligent interactive health education model can improve the health education effect of the smokers with high risk of developing COPD, and improve the health behavior of the population.
ABSTRACT
Objective:To analyze the screening status of high-risk population of chronic obstructive pulmonary disease (COPD) in areas where “Happy Breathing” project was carried out.Method:There were 1 008 518 COPD screening questionnaires (COPD-SQ) filled out in 18 pilot areas of “Happy Breathing” program from November 2017 to October 2019. Within subjects who scored 16 points or more with COPD-SQ, 63 523 of them underwent pulmonary function tests before bronchodilator inhalation. Stratified analysis, chi-square test and other statistical methods were performed to analyze the distribution of COPD high-risk groups, the prevalence of COPD among high-risk groups and risk factors of COPD.Results:Results in this study suggested that the high-risk population of COPD accounted for 18.99% (191 498/1 008 518) of the population who received the questionnaire screening. Among the high-risk population who received lung function test, 31.59% (20 070/63 523) were screened and diagnosed as COPD patients. As for risk factors of COPD, the proportion of high-risk population was higher in people with a smoking index ≥600 compared with never-smokers (54.20% vs 12.60%), and the prevalence of COPD was also higher in people with a smoking index ≥600 (35.62% vs 25.22%); people who were exposed to second-hand smoke almost every day also showed an increased proportion of high-risk groups (27.39% vs 10.97%) and a high prevalence of COPD (31.36% vs 27.93%) than those without second-hand smoke exposure; the presence or absence of biofuel exposure also caused the difference in the proportion of high-risk groups (33.92% vs 13.11%); compared with people without a family history of respiratory diseases, the proportion of high-risk groups (56.38% vs 16.42%) and the prevalence of COPD in high-risk groups (32.40% vs 29.19%) were both higher in those with family history of respiratory diseases.Conclusion:The high-risk group of COPD accounts for a high proportion of the screened population, suggesting that the “Happy Breathing” project is feasible and necessary in COPD screening, which is helpful for the development of COPD diagnosis and treatment.
ABSTRACT
Objective To investigate the application value of serum auto-antibody detection combined with low-dose spiral computed tomography (LDCT) in early lung cancer screening. Methods From 12568 medical examination crowd (7453 males and 5115 females), 1324 people with high-risk cases of lung cancer in our medical examination center were divided randomly into three groups (LDCT, serum auto-antibody, and serum auto-antibody combined with LDCT groups). All people in this research were screened by chest X-ray. Follow-up was conducted for one year, and the positive screening and diagnosis rates of early lung cancer screening were compared between these groups of high-risk people with lung cancer. Results The positive screening and diagnostic rates of high-risk lung cancer in the serum auto-antibody combined with LDCT group was significantly higher those that in other two groups (P < 0.001). The specificity and sensitivity of serum auto-antibody combined with LDCT group were 89.1% and 88.4%, respectively; the area under the ROC curve was 0.863. Conclusion Serum auto-antibody detection combined with low-dose spiral CT can significantly improve the positive screening rate of lung cancer in high-risk populations, providing a strong theoretical support for lung cancer screening pathway.
ABSTRACT
Objective:To investigate the risk of lung cancer and screening results of residents in 3 cities of Shanxi Province from 2014 to 2018.Methods:Cluster random sampling method was used to select permanent residents from 3 cities (Taiyuan, Jincheng and Yangquan) in Shanxi Province from January 2014 to December 2018 for lung cancer risk assessment. People at high risk of lung cancer were screened by low-dose spiral CT. The screening results were analyzed and the influencing factors of lung cancer occurrence were analyzed by unconditional logistic regression.Results:184 539 people were included in the survey, and 36 790 people (19.94%) were at high risk of lung cancer. The detection rate of high-risk of lung cancer in men was higher than that in women [29.76% (25 690/184 539) vs. 11.30% (1 100/184 539), χ2 = 10.44, P = 0.001]. A total of 12 660 people (34.41%) at high risk of lung cancer participated in clinical screening, and 3 038 people (24.00%) were positive in clinical screening for lung cancer. There were no statistical differences in the positive rate of clinical screening among people at high risk of lung cancer with different gender, nationality, education, marital status, occupation, history of harmful substance exposure, coal burning, clean heating, indoor oil fumes, and history of pulmonary tuberculosis (all P > 0.05). There were statistical differences in the positive rate of clinical screening among people at high risk of lung cancer with different age, smoking, drinking, drinking tea, physical exercise, exposure time of second-hand smoke, living environment air pollution, history of emphysema, history of pneumoconiosis, family history of lung cancer, mental depression, and history of trauma (all P < 0.05). Logistic regression analysis showed that age ≥ 50 years old, smoking, exposure to second-hand smoke for 1-14 years, living environment air pollution, history of emphysema, family history of lung cancer, and mental depression were the risk factors for positive clinical screening in people at high risk of lung cancer (all P < 0.05), and physical exercise was the protective factor for positive clinical screening in people at high risk of lung cancer ( P < 0.05). Conclusions:The screening rate of people at high risk of lung cancer in 3 cities of Shanxi Province needs to be improved. The detection rate of intrapulmonary nodules in people at high risk of lung cancer is mainly affected by age, smoking, exposure time of second-hand smoke, family history of lung cancer, history of emphysema and other factors.
ABSTRACT
Objective:To search, evaluate and summarize the evidence on prediabetes management in high-risk population with gestational diabetes mellitus (GDM).Methods:Two researchers independently screened the evidence according to the inclusion criteria and exclusion criteria. The quality of the included evidence was evaluated by the clinical guideline research and evaluation system (AGREE Ⅱ). The quality of the evidence and the strength of recommendation were graded by the GRADE system. According to the clinical nursing practice guidelines for gestational diabetes mellitus, the recommendations for GDM high-risk groups were extracted.Results:A total of 14 pieces of evidence were included, including 4 guidelines, 2 consensus, 5 practice guidelines and 3 diagnosis and treatment standards. 29 pieces of recommendations for prediabetes management of high-risk population with gestational diabetes mellitus were summarized from five aspects, including disease risk assessment, prenatal examination guidance, management objectives of gestational weight and blood glucose, diet guidance and exercise guidance.Conclusion:The evidence of prediabetes management of high-risk population with gestational diabetes mellitus is scientific and reliable.
ABSTRACT
Objective:To understand the risk characteristics of high-risk population of chronic disease in Shanghai， and provide theoretical basis for screening management and health intervention. Methods:The data from the 2013 Shanghai Non-communicable and Chronic Diseases Surveillance was used for analysis. People （aged 35 and over） who had no diagnosis of hypertension， diabetes and dyslipidemia but met the criteria for high-risk groups of chronic diseases were included in the study. Finally， 3 682 participants were included. Results:In this high-risk population， 62.90% of the subjects has total serum cholesterol level of 5.2-6.2 mmol/L， 35.88% had blood pressure level of （130-139）/（85-89） mmHg， 30.50% had abdominal obesity， 27.68% were current smokers， and 8.75% had fasting blood glucose level of 6.1-7.0 mmol/L. Among the different risk characteristics， the detection rate of smoking risk in men was higher than that in women （64.51% vs. 1.49%）. On the contrary， the detection rate of waist circumference and serum total cholesterol risk in women was higher than that in men （34.90% vs. 24.31% and 72.30% vs. 49.67%， respectively）. The differences were statistically significant （P<0.05）. The detection rates of the five high-risk characteristics were not the same in all age groups. The detection rate of blood pressure risk was relatively low， and the cholesterol risk was relatively high in the highly educated population. The blood pressure risk was the highest among agricultural practitioners （42.26%）. The detection rate of smoking risk was the highest in rural areas （31.45%）， and the risk of cholesterol was the highest in urban areas （68.54%）. The differences were statistically significant （P<0.05）. Among the high-risk groups of chronic diseases in Shanghai， the distribution of high-risk characteristics in genders， ages， and occupational types were not the same and the differences were statistically significant （P<0.05）. Conclusions:The level of risk characteristics among high-risk groups of chronic diseases in Shanghai is relatively high. Relevant departments should carry out targeted health interventions for different populations to reduce the level of risk factors in high-risk groups of chronic diseases and control the potential risk of chronic diseases.
ABSTRACT
Objective:To understand the epidemiological characteristics of high-risk population of hypertension in Shanghai， and to provide references for health management and targeted lifestyle intervention of the high-risk population in community. Methods:The data from the 2013 Shanghai Non-communicable and Chronic Diseases Surveillance were used. The subjects who met the criteria of high-risk population of hypertension were included， and 11 753 subjects were finally identified， to analyze the distribution and level of risk characteristics. Result:Among six high-risk characteristics of hypertension， the detection rate of high salt in diet was the highest （55.3%）， followed by overweight/obesity （44.0%）， family history of hypertension （41.6%）， and blood pressure level of （130-139）/（85-89） mmHg （31.7%）. The detection rate of excessive drinking was the lowest （5.0%）. The percentage of population with one or two high-risk characteristics was higher than that with three or more high-risk characteristics （76.9% vs. 23.1%）. Systolic blood pressure， diastolic blood pressure， fasting plasma glucose level， and body mass index in the male high-risk group were higher than those in the female group， and the differences were statistically significant （P<0.05）. Systolic blood pressure， diastolic blood pressure， fasting plasma glucose level， body mass index and daily salt intake were different between different age groups， educational level and occupational types （P<0.05）. Systolic blood pressure， diastolic blood pressure， body mass index and daily salt intake were significantly different among high-risk groups with different marital status （P<0.05）. The daily salt intake and systolic blood pressure levels of high-risk population in different areas were significantly different （P<0.05）. Conclusion:We should identify high-risk groups of hypertension as early as possible and actively carry out community health management and targeted lifestyle interventions. The focus should be on the groups and individuals with high-risk characteristics such as dietary high salt and overweight/obesity， male， middle-aged and low-educated groups. In this way， we can reduce the level of high-risk characteristics， prevent and delay the occurrence of hypertension.

Donation related vasovagal reaction(DRVR) is the most common adverse reaction during blood donation. It is very important for blood banks to identify, treat and prevent DRVR accurately. At present, it is generally believed that psychological factors are the first major inducement of DRVR. Applied muscle tension (AMT) and salt supplementation have been proved to be effective interventions for vasovagal response; the identification methods of high-risk groups such as State Trait Anxiety Inventory, Medical Fear Inventory and Blood Donor Response Scale have been relatively mature, but the utilization rate is relatively low in China. In this paper, the main clinical manifestations, pathogenesis, research methods, related factors, management and prevention measures of DRVR, as well as the identification of high-risk groups before blood donation are reviewed.
ABSTRACT
Objective To understand the prevalence and risk factors of Toxoplasma gondii infections among high-risk populations in Changzhou City, so as to provide the scientific basis for formulating effective control measures of toxoplasmosis. MethodsFour types of high-risk populations living in Changzhou City were recruited from 2016 to 2018 as the study subjects, including HIV/AIDS patients, cancer patients, pregnant women and livestock and poultry breeding or processing workers. Each subject was investigated for the knowledge on knowledge, attitude and practice of toxoplasmosis prevention and control. In addition, serum specific IgG and IgM antibodies against T. gondii were detected, and the risk factors of T. gondii infections were identified. Results A total of 900 participants at high risk of T. gondii infections were investigated in Changzhou City from 2016 to 2018, including 150 HIV/AIDS patients, 250 cancer patients, 250 pregnant women and 250 livestock and poultry breeding or processing workers. The overall awareness rate of toxoplasmosis prevention and control knowledge was 16.8% (151/900), and the awareness rate was significantly greater in women than in men (χ2 = 41.34, P < 0.05). The awareness rate of toxoplasmosis prevention and control reduced with ages (χ2 = 147.78, P < 0.05), and increased with the education level (χ2 = 166.42, P < 0.05). In ad dition, there was an occupation-specific awareness rate of toxoplasmosis prevention and control (χ2 = 92.26, P < 0.05), and the highest awareness rate was seen in cadres and staff (47.2%, 34/72). Among all high-risk populations, 34.6% (311/900) had fre- quent contacts with cats/dogs, 40.4% (364/900) raised cats/dogs at home, 0.9% (8/900) ate raw meat, and 15.8% (142/900) sepa- rated chopping boards for raw and cooked food. Among the participants aware of toxoplasmosis prevention and control knowledge, 24.5% (37/151) contacted cats/dogs frequently, which was significantly lower than those not aware of toxoplasmosis prevention and control knowledge (36.6%, 274/749) (χ2 = 8.11, P < 0.05), and 35.1% (53/151) separated chopping boards for raw and cooked food, which was significantly higher than those not aware of toxoplasmosis prevention and control knowledge (11.9%, 89/749) (χ2 = 50.97, P < 0.05). The overall seroprevalence of T. gondii infections was 11.0% (99/900), and the positive rates of IgG antibodies against T. gondii were 6.0%, 13.9%, 4.8% and 17.3% in HIV/AIDS patients, livestock and poultry breeding or processing workers, pregnant women and cancer patients, respectively (χ2 = 25.87, P < 0.05). A higher seroprevalence of T. gon- dii infection was seen in men than in women (χ2 = 8.88, P < 0.05), and the seroprevalence increased with ages (χ2 = 37.03, P < 0.05) and reduced with education levels (χ2 = 25.07, P < 0.05). There was an occupation-specific seroprevalence of T. gondii in- fection (χ2 = 22.09, P < 0.05), and the highest seroprevalence was detected in peasants (57/330, 17.3%). Conclusions The awareness of toxoplasmosis prevention and control knowledge is low among high-risk populations in Changzhou City. Health edu- cation pertaining to toxoplasmosis prevention and control requires to be strengthened in cancer patients and livestock and poultry breeding or processing workers who have a high seroprevalence of T. gondii infections, so as to change the poor behavior styles.
ABSTRACT
Objective To investigate the prevalence of COPD in high-risk population in Suzhou, and to explore the corresponding measures against cognitive misunderstanding. Methods From January 2017 to January 2020, a total of 4,800 residents from 4 COPD national monitoring points in Suzhou were selected using a multi-stage stratified cluster sampling method. Questionnaire surveys and lung function tests were conducted. The high-risk groups of COPD and their morbidity and COPD awareness were statistically analyzed. The influencing factors of COPD in Suzhou were analyzed by single factor analysis and multi-factor stepwise logistic regression analysis. Results A total of 4 747 residents were included in the analysis, including 4 249 people with high-risk COPD and 441 confirmed patients. Among them, 75.96% had basic knowledge, 52.15% understood the treatment knowledge, 49.89% understood the self-management, and 61.68% understood the lung rehabilitation training. Multivariate stepwise logistic regression analysis showed that age (OR=1.557, 95%CI=1.202~2.017), daily smoking (OR=2.062, 95%CI=1.673~2.541), cooking fuel being polluted (OR=1.526,95%CI=1.255~1.900), and occupational dust exposure>1 year (OR=1.474, 95%CI=1.196~1.816) were risk factors for COPD, while kitchen with smoke exhaust equipment (OR=0.601, 95%CI=0.465~0.777) and ethnic minorities (OR=0.642, 95%CI=0.508~0.812) were COPD protective factors (P<0.05). Conclusion The incidence of COPD in high-risk population aged ≥40 years in Suzhou area was higher, and the patients' cognitive level was lower. It is necessary to strengthen science popularization, improve health awareness, and reduce the related risk factors.
ABSTRACT
Objective To evaluate the efficacy of stroke prevention project for screening community stroke population by analyzing the dynamic alteration of risk factors and the control levels for stroke in the Wanshoulu community from 2011 to 2017. Methods We retrospectively analyzed the database of the Wanshoulu community population of stroke screening in2011(n = 10 379),2013 (n = 2 364),2015 (n = 6 048) and 2017 (n = 3 497). The population in 2011 and 2013 were first screening population (covered rate reached 84. 7% in the population aged ≥40 years old), and the population in 2015 and 2017 were re-examination population. We analyzed the dynamic alteration in the proportion of eight risk factors of stroke (hypertension, diabetes, dyslipidemia, smoking, less physical exercise, atrial fibrillation, obesity, and family history), the awareness rate and the control rate of three risk factors(hypertension, diabetes, and dyslipidemia), and the risk categories of stroke from 2011 to 2017. Results Compared with the data in 2011 and 2013, the proportion of patients with six risk factors in 2015 and 2017, including hypertension(26.8% [1623/6 048], 27.2% [952/3 497] ta.30.9% [3 210/10 379], 33.7% [796/2 364]), atrial fibrillation (2.1% [124/6 048], 1.6% [57/3 497] vs. 6. 7% [691/10 379], 2.7% [64/2 364]), smoking (11.9% [718/6 048], 7. 7% [268/3 497] vs. 17. 8% [1 845/10 379], 14.5% [343/2 364]), dyslipidemia (15.3% [928/6 048], 15.0% [526/3 497] vs. 17. 5% [1814/10 379], 22.0[519/2 364]), less physical exercise (18.4% [1 112/6 048], 17. 1% [598/3 497] vs. 24. 1 % [2 497/10 379], 33.0% [780/2 364]), and obesity (12.7% [769/6 048], 5.4% [190/3 497] vs. 12.9% [1 337/10 379], 17.0% [403/2 364]), gradually decreased over the time(all P <0. 01). Meanwhile, the proportion of high-risk stroke population decreased (22. 9% [2 373/10 379], 19. 9% [470/2 364], 17. 9% [1 083/6 048], 17.0% [595/3 497]) in 2011, 2013, 2015 and 2017, respectively. χ2=158.331, P<0.01). Compared with that in 2011, the awareness rate and control rate of hypertension, diabetes mellitus, and dyslipidemia were all increased in 2017(all P<0.01). Conclusion Since the performance of stroke prevention project in 2011, the risk factors of stroke have been well controlled, and the proportion of high-risk stroke population has been decreasing.
