ABSTRACT

Objective: To estimate the cervical and breast cancer screening coverage and related factors among women aged 35-69 years who were in the National Cervical and Breast Screening Program, to provide evidence for improving cervical and breast cancer control and prevention strategy. Methods: Data used in this study were abstracted from the 2013 Chinese Chronic Diseases and Risk Factors Surveillance Program. A total of 66 130 women aged 35-64 years and 72 511 women aged 35-69 years were included for this study. Weighted prevalence, (with 95% confidence interval, CI) was calculated for complex sampling design. Rao-Scott χ(2) method was used to compare the screening coverage among subgroups. A random intercept equation which involved the logit-link function, was fitted under the following five levels: provincial, county, township, village and individual. Fix effects of all explanatory variables were converted into OR with 95%CI. Results: In 2013, 26.7% (95%CI: 24.6%-28.9%) of the 35-64 year-old women reported that they ever had been screened for cervical cancer and 22.5% (95% CI: 20.4%-24.6%) of the 35-69 year-olds had ever undergone breast cancer screening. Lower coverage was observed among women residing in rural and central or western China than those in urban or eastern China (P<0.000 1). The coverage among women aged 50 years or older was substantially lower than those aged 35-49 years. Those who were with low education level, unemployed, low household income and not covered by insurance, appeared fewer number on this cervical or breast cancer screening program (P<0.000 1). Women living in rural and western China were having less chance of receiving the breast cancer screening (P<0.05), but the difference was not statistically significant. Conclusion: It is essential to strengthen the community-based cervical and breast cancer screening programs, in order to increase the coverage. More attention should be paid to women aged 50 years or older, especially those socioeconomically disadvantaged ones.

ABSTRACT

Objective: To analyze the rates on prevalence, awareness, status on treatment and control of type 2 diabetes mellitus among Chinese premenopausal women aged 18-49, in 2013. Methods: Data on China Chronic and Non-Communicable Disease Surveillance in year 2013 was used for analysis. Source of data covered 302 surveillance points which were selected by Multi-stage cluster random sampling method that including 176 534 adults over 18 years of age, with 46 674 premenopausal women aged 18-49. Plasma glucose and hemoglobin A1c levels were determined after a 10-hour overnight fast for all the participants, before a 2-hour oral glucose tolerance test was conducted among participants without a self-reported history of diagnosed diabetes. Diabetes was defined according to the 1999 WHO diagnostic criteria-fasting blood glucose level as ≥7.0 mmol/L and/or 2 hours oral glucose tolerance test (OGTT-2 h) level as ≥11.1 mmol/L. After being weighed, according to complex sampling scheme and post-stratification, the sample was used to estimate the rates of prevalence, awareness, treatment and control of type 2 diabetes mellitus by age, education, urban and rural areas, and geographic locations. Results: The overall prevalence of type 2 diabetes mellitus was 5.6% among the Chinese premenopausal women aged 18-49. No statistical difference on the prevalence rates (5.7% and 5.4%, respectively) was seen, between participants from the rural or the urban areas. Prevalence rates in the eastern, central or western geographic areas were 5.8%, 6.2% and 4.4% respectively. The rates of awareness, treatment and control of diabetes appeared as 29.3%, 27.9% and 29.4% in childbearing women aged 18-49. The rate of treatment was 95.4% among those who knew their diabetic situation in childbearing women aged 18-49 years. The control rate of diabetes was 38.9% among those who had taken measures to control glucose, in 18-49-year-old childbearing women. The rate of awareness on diabetes in childbearing women aged 18-49 years in urban areas was higher than that in the rural areas. There were significantly statistical differences on the treatment rates among groups of different education levels but not in the trend test. Conclusion: The prevalence of type 2 diabetes mellitus in childbearing women aged 18-49 appeared high, but with low rates on awareness, treatment and control. However, statistical difference was seen on awareness, between urban and rural areas.

ABSTRACT

Objective: To explore the relations between the prevalence of multiple chronic diseases and cigarette smoking behavior in the Chinese adults. Methods: Based on the results: from the 2013 Chronic Disease Risk Factor Surveillance (NCD Surveillance), 176 534 Chinese residents aged 18 years and above, covering 298 counties (districts) in 31 provinces, was randomly recruited, using the multi-stage stratified clustering sampling method. Information on demographics, cigarette smoking (status, quantity and period) was obtained through face-to-face interviews and questionnaires. Anthropometric data and blood samples were collected and properly stored for analysis. Results In total, 175 386 adults were included for statistical analyses, with 42.7% as males and 57.3% as females. The prevalence rates of hypertension, high total cholesterol and high triglycerides were 30.4%, 7.2% and 18.0% in male smokers, 35.6%, 14.0%, 10.3% and 15.9% in female smokers respectively, which were all higher than those in the respective non-smokers. Male smokers were found under lower risk on hypertension, but 19% higher on total glycerides when compared with non-smokers of the same sex(OR=1.19, 95%CI:1.10-1.30), when multiple risk factors were under control. Male current smokers with more than 20 cigarettes per day have 41% (OR=1.41, 95%CI: 1.28-1.55) higher risk of high TG than non-smokers. Female smokers presented 40% (OR=1.40, 95%CI: 1.15-1.70) higher risk in high glycerides than the non-smokers. Specifically, women smoking longer than 20 years have 60% (OR=1.60, 95%CI: 1.31-1.95) higher risk of high TG than women smoking less than 20 years. Conclusions: Prevalence rates of certain chronic diseases were seen higher in smokers of both genders. People with longer history of smoking or being heavier smokers, appeared at advanced risk on developing chronic diseases.

ABSTRACT

Objective: To investigate the demographic characteristics of falls and fall-related injuries in Chinese elderly population. Methods: In 2013, the 4(th) round Chronic Non-communicable Disease and Risk Factor Surveillance in China was conducted in 31 provinces. A stratified multi-stage cluster sampling was used to select the samples. A total number of 98 629 community-based adults aged 60 years and older received a set of standardized questionnaires with a face to face interview. The prevalence rates of falls and consequent injuries were compared between different genders, age groups, levels of education and areas of residency. Results: The overall prevalence of falls among elderly in the previous 6 months was 8.0%(95%CI: 7.5%-8.5%). The prevalence was increasing with age and decreasing with the levels of education, and higher in females (9.1%) than in males (6.8%), with differences statistically significant (χ(2)=74.1, P<0.01). Prevalence rates were also seen higher in rural (8.6%), in widowed (11.0%) residents and in farmers or house workers than those in urban areas (7.2%), in non-widowed (7.0%), or having other jobs, with differences all statistically significant (χ(2)=7.7, P<0.01, χ(2)=128.0, P<0.01). 52.6% of the elderly got injured when fell. The proportion of injury was greater in females (54.8%) than that in males (49.6%), with differences statistically significant (χ(2)=10.2, P<0.01). Proportion of most frequent types of injuries were hip fractures (7.3%), hand/arm fractures (12.5%), head injury (8.0%) and bruise (53.6%) respectively. The proportion of hip fractures was 12.4% in elderly over 80 year of age, also was the highest. Conclusions: Results from the present study showed that elderly suffered high prevalence of falls.Statistically significant differences were seen in residents with different groups as genders, age, education levels, marital status, urban/rural areas or jobs. Group-based comprehensive prevention and intervention on falls should be strengthened.

ABSTRACT

Objective: To study the relationship between blood pressure level and major risk factors for cardiovascular diseases in adults in China. Methods: A total of 179 347 adults aged ≥18 years were recruited from 298 surveillance points in 31 provinces in China in 2013 through complex multistage stratified sampling. The survey included face to face interview and physical examination to collect information about risk factors, such as smoking, drinking, diet pattern, physical activity, overweight or obesity, and the prevalence of hypertension. The blood pressure was classified into 6 levels (ideal blood pressure, normal blood pressure, normal high blood pressure and hypertension phase Ⅰ, Ⅱ and Ⅲ). The relationship between the prevalence or co-prevalence of risk factors for cardiovascular disease and blood pressure was analyzed. Results: The adults with ideal blood pressure, normal blood pressure, normal high pressure, hypertension phase Ⅰ, Ⅱ and Ⅲ accounted for 36.14%, 22.77%, 16.22%, 16.43%, 5.97% and 2.48%, respectively. Among them, the blood pressure was higher in men, people in Han ethnic group and those married, and the blood pressure was higher in those with older age, lower income level and lower education level, the differences were all significant (P<0.05). Whether taking antihypertensive drug or not, co-prevalence of risk factors influenced the blood pressure levels of both sexes (P<0.05), and the blood pressure levels of those taking no antihypertensive drug was influenced more by the co-prevalence of risk factors. Finally, multiple logistic analysis showed that the risks for high blood pressure in adults with 1, 2 and ≥3 risk factors were 1.36, 1.79 and 2.38 times higher, respectively, than that of the adults without risk factor. Conclusion: The more the risk factors for cardiovascular disease in adults, the higher their blood pressure were. It is necessary to conduct comprehensive behavior intervention targeting ≥ 2 risk factors for the better control of blood pressure in general population.

ABSTRACT

Objective: To investigate the prevalence and influencing factors on respiratory disease related symptoms (coughing, expectoration, persistent coughing and persistent expectoration) in Chinese people ≥40 years old. Methods: Data was collected from 162 surveillance points in the China Non-communicable and Chronic Disease Surveillance Project in 2010. A total number of 56 066 people, aged ≥40 years, were selected by multi-stage cluster random sampling method in this study. The prevalence rates of coughing, expectoration, persistent coughing and persistent expectoration were calculated according to gender by χ(2) test. Multivariate logistic regression model was used to analyze the related influencing factors. Results: The prevalence rates of coughing, persistent coughing, expectoration and persistent expectoration in men were significantly higher than that in women (P<0.01). The prevalence rate of respiratory symptoms was positively correlated with age and duration and amount of cigarette smoking (P<0.01), while negatively correlated with participants'education level (P<0.01). Results from multivariate logistic regression analysis showed that gender, age, education level, smoking-related parameters, areas of residency (in urban or rural areas), etc. were appeared as influencing factors on the prevalence of respiratory symptoms. Conclusion: The symptoms of chronic respiratory diseases appeared prevalent in Chinese population aged ≥40 years. Factors as older age, living in the central/western regions and smoking-related parameters were identified as of higher risks.
