Objective
To investigate the morbidity of ocular fundus diseases in Tibetan above 40 in Maqin county, Qinghai Province.
Methods
A total of 2511 Tibetan above 40 in Maqin county, Qinghai Province were seelected by cluster sampling method. The sampling survey of ocular fundus diseases was performed on the individuals with indirect ophthalmoscope, and the results were compared with the domestic existing epidemiological data.
Results
Two hundred and thirty five (9.35%) cases were found to have abnormal ocular fundus, and the blindness rate due to the abnormal ocular fundus was 20.5% (80/391 eyes) which was lower than the blindness rate due to cataract (52.5%). Low vision and blindness led by ocular fundus diseases were found in 155 eyes (65.96%)，including 74(47.74%) with age-related macular degeneration (AMD) and 23 (9.79%) with retinoangiopathy.
Conclusions
The morbidity of ocular fundus disorder is higher in high plateau than that in backland; AMD and retinoangiopathy are the main diseases leading to blindness.

ObjectiveTo investigate the prevalence of chronic obstructive pulmonary disease (COPD) and related risk factors in two districts and five counties in Jiaxing city of Zhejiang province.
MethodsWe randomly selected people over the age of 40 in 10 communities of two districts and five counties in Jiaxing city by cluster sampling and random sampling to investigate the prevalence of COPD from January 2013 to December 2013. All included patients received pulmonary function test at the same time.
ResultsA total of 1 256 cases of adults over the age of 40 were included, among which, 1 056 cases with complete data and qualified for pulmonary function test. There were 410 males with mean age of 58.74±11.62, and 646 females with mean age of 59.45±11.72. The overall prevalence of COPD was 13.60%. Male and female prevalence rates were 13.90% and 13.41%, respectively. Divided by age, the prevalence of the age of 40 to 50 was 3.38%, the age of 51 to 60 was 9.57%, the age of 61 to 70 was 19.15%, and the age of above 70 was 29.35%. The results of multivariate logistic regression analysis showed that the main risk factors of COPD were smoking, passive smoking, history of dust exposure, chronic respiratory disease history and age.
ConclusionThe total prevalence of COPD in Jiaxing area is high, and the female prevalence rate is especially higher than the national average level, which is the epidemiological characteristic of this area. Because the risk factors of COPD are complex, an integrated control strategy should be adopted.
ObjectiveTo systematically review the prevalence and risk factors of the chronic post-cesarean section pain (CPCSP). MethodsPubMed, EMbase, The Cochrane Library, CINAHL, PsycInfo, CBM, WanFang Data, VIP, and CNKI databases were electronically searched to collect studies on the prevalence and risk factors of CPCSP from inception to August 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 15.1 software. ResultsA total of 43 studies involving 12 435 participants were included. The results of meta-analysis showed that the prevalence of CPCSP for 2 to 5 months, 6 to 11 months, and at least 12 months were 19% (95%CI 15% to 23%), 13% (95%CI 9% to 17%), and 8% (95%CI 6% to 10%), respectively. The risk factors included preoperative pain present elsewhere, postoperative severe acute pain, low abdominal transverse incision, non-intrathecal administration of morphine, preoperative anxiety, postpartum depression, etc. ConclusionsThe current evidence shows that the overall prevalence of CPCSP is high. Preoperative pain presents elsewhere, postoperative severe acute pain, low abdominal transverse incision, non-intrathecal administration of morphine, preoperative anxiety and postpartum depression may increase the risk of CPCSP.
ObjectiveIn order to improve the prevention and treatment of bronchial asthma, the prevalence and risk factors of asthma in Chengdu among residents over 14 years old were investigated.MethodsA cross-sectional survey was conducted in Chengdu. The inhabitants (age > 14 years) recruited in this household questionnaire survey were through multi-stage cluster random sampling. Univariate and multivariate logistic regression were used to analyze the risk factors of asthma.ResultsA total of 3 477 subjects were finally recruited in this study. Of them, 131 were asthmatic patients; and the prevalence rate was 3.8%. There were significant differences observed in the prevalence of asthma among people of different ages, residences, occupations and educational levels (χ2=191.084, P<0.05; χ2=9.114, P<0.05; χ2=114.268, P<0.05; χ2=62.123, P<0.05). Univariate regression analysis showed that the risk factors of asthma included five factors (measles, chickenpox, pneumonia, tracheobronchitis and intestinal parasitic diseases) related to childhood illness, and two factors (asthma and chronic bronchitis) related to the first-degree relatives (P<0.05). In addition, active smoking history was a risk factor for asthma in men (P<0.05). Multivariate logistic regression indicated that measles, pneumonia, tracheobronchitis, intestinal parasitic diseases in childhood and first-degree relatives suffering from asthma were independent risk factors for asthma.ConclusionsThis study describes the epidemiological characteristics of asthma in Chengdu among adolescents (age>14 years) and adults. The history of measles, pneumonia, tracheobronchitis, and intestinal parasitic diseases in childhood, and first-degree relatives suffering from asthma are the independent risk factors for asthma. In addition, active smoking history is a risk factor for asthma in men.
ObjectiveTo investigate the blood pressure level and prevalence of hypertension in middle-aged people with positive family history of hypertension in Chengdu area, compare the differences between middle-aged people with positive family history of hypertension and middle-aged people with negative family history of hypertension, and explore the influencing factors of hypertension in middle-aged people with positive family history of hypertension.MethodsFrom September 2013 to March 2014, the stratified sampling method was used to survey 3 096 middle-aged people aged 40-59 years in Chengdu. Their height, weight, blood pressure, blood glucose, and blood lipids were measured. Questionnaire surveys were conducted using a uniformly designed questionnaire. The blood pressure levels and hypertension prevalences were compared between people with and without positive family history of hypertension. The influencing factors of hypertension in middle-aged people with positive family history of hypertension were analyzed using multiple logistic regression.ResultsThere were significant differences between the middle-aged people with positive family history of hypertension and the ones with negative family history of hypertension in systolic blood pressure [(137.4±22.4) vs. (118.0±11.3) mm Hg (1 mm Hg=0.133 kPa), P<0.001], diastolic blood pressure [(84.1±12.2) vs. (73.9±7.7) mm Hg, P<0.001], and prevalence of hypertension (28.6% vs. 22.2%, P<0.001). Ageing [odds ratio (OR)=1.107, 95% confidence interval (CI) (1.071, 1.144), P<0.001], monthly personal income ≥3 000 yuan [OR=1.566, 95%CI (1.003, 2.445), P=0.048], and abdominal obesity [OR=1.658, 95%CI (1.091, 2.520), P=0.018] were the risk factors for hypertension in middle-aged males with positive family history. Ageing [OR=2.257, 95%CI (1.202, 4.025), P=0.026] and overweight or obesity [OR=2.365, 95%CI (1.653, 3.385), P<0.001] were the risk factors, and physical exercise [OR=0.529, 95%CI (0.304, 0.918), P=0.024] was the protective factor for hypertension in middle-aged females with positive family history.ConclusionsThe prevalence of hypertension is high in middle-aged population with positive family history of hypertension in Chengdu and is significantly higher than that in the ones with negative family history of hypertension. Strengthening health education on hypertension-related knowledge, and reasonably controlling waist circumference and body weight may have positive significance in preventing or delaying the occurrence of hypertension in people with positive family history of hypertension.

Objective
To investigate the incidence and the correlative factors of diabetic retinopathy (DR) in patients with diabetes mellitus（DM）who lives in Beixinjing blocks, Shanghai.
Methods
Residents with DM were enrolled according to resident health archives. The data of disease history, visual acuity, eye disease and introcular pressure were collected by inquiry and examination. Photography of ocular fundus was used to confirm the diagnosis of DR.
Results
A total of 535 residents excepted the examination with the participating rate of 90.68%, in whom 146 (27.29%) were identified as with DR. The incidence of single and proliferative DR was 22.29% and 4.30%, respectively. Duration of DM was the independent risk factor of DR, while long duration of DM, accompanied with peripheral neuropathy and body mass index was the in-order independent factor of proliferative DR.
Conclusions
The incidence of DR is high in residents with DM. Monitoring DR progress in DM residents with risk factors is recommended.

Objective
To investigate the prevalence and related factors of diabetic retinopathy (DR) among residents with type 2 diabetes mellitus (T2DM) in Culai Town of Tai'an City in Shandong Province.
Methods
According to the DM management file database for community, 785 patients with T2DM were randomly selected by cluster sampling method. The questionnaires, routine general examinations, visual and fundus-free fluoroscopy were performed on all the patients. DR diagnosis and classification was according to the guidelines for clinical diagnosis and treatment of DR in China (2014). Both monocular and binocular DR were selected as DR patients, and the worse eye for binocular DR were treated as the DR classification of the patient. The patients were grouped by presence or absence of DR. GraphPad Prism 6, SigmaPlot 12.5, SPSS 20.0 and Excel were used to achieve data analysis. Also, SPSS 20.0 was used for multi-factor logistic regression analysis.
Results
A total of 699 patients (89.04%) were actually recorded. There were 122 eyes of 63 patients (9.01%) with DR (DR group), 1272 eyes of 636 patients (90.99%) without DR (NDR group). Among the 122 eyes of DR, there were 19 (15.57%), 17 (13.93%), 70 (57.38%), 10 (8.20%), 6 (4.92%) eyes in stage Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, respectively. The differences of mean age (t=15 290, P=0.002), DM duration (t=9075, P＜0.000) and diastolic blood pressure (t=15 810, P=0.006) between the two groups were statistically significant. There were 23 (36.51%) and 394 (61.95%) patients with hypertension history in the DR group and the NDR group, with the significant difference ( χ2=15.42, OR=0.35, 95%CI 0.21-0.60). There were 57 (90.48%) and 500 (78.62%) patients with fasting blood glucose larger than 6.11 mmol/L in the DR group and the NDR group, with the significant difference (OR=2.51, 95%CI 1.06-5.95, P=0.031). Logistic regression analysis showed that the age, fasting blood glucose and DM duration were influencing factors for DR (OR=1.039, 0.864, 0.898; P=0.021, ＜0.000, ＜0.000).
Conclusion
The prevalence of DR in patients with T2DM in Culai Town of Tai'an City is 9.01%. Age, DM duration, fasting blood glucose are associated to DR. Those with a history of hypertension may have a lower risk of DR than those without a history of hypertension.
ObjectiveTo investigate the prevalence and risk factors for chronic obstructive pulmonary disease (COPD) in Dayi County of Chengdu.
MethodsRandomly cluster sampled residents between 40 and 70 years of age from two natural villages in the rural communities from February to December, 2010 were included in our study. We used questionnaire survey, physical examination and portable spirometry to collect data. Post-bronchodilator forced expiratory volume in 1 second/forced vital capacity of less than 70% was defined as the diagnostic criterion of COPD. Univariate analysis and logistic regression mode were used to define the risk factors.
ResultsA total of 1 017 residents were enrolled in this survey, and 782 participants were valid for analysis, with a valid response rate of 76.89%. There were 330 males and 452 females, with an average age of (51.97±8.17) years old. The overall prevalence of COPD was 10.61%. After population standardization, the prevalence rate was 12.37%, and the overall prevalence increased with increment of age. The prevalence in male (13.33%) was higher than that in female (8.62%) with significant difference (P<0.01) and the prevalence increased with age. Univariate analysis showed that sex, age, education level, smoking and amount of smoking (pack-years) were the risk factors for COPD with significant difference. Logistic regression analysis showed that age, amount of smoking (pack-years) were the main risk factors for COPD.
ConclusionCOPD is highly prevalent in Dayi County of Chengdu and it is important to prevent COPD by controlling smoking and improving education level.
