Objective: To estimate the burden of disease (BOD) attributable to main risk factors of chronic diseases in Zhejiang Province in 2017, so as to provide the evidence for formulating the control strategy for chronic diseases and reducing BOD. Methods: The results of the Global Burden of Disease Study 2017 ( GBD 2017 ) were extracted to evaluate years of life lost due to premature mortality ( YLL ), years lived with disability ( YLD ) and disability-adjusted life years ( DALY ). The gender- and age-specific BOD attributable to main risk factors of chronic diseases, including the environment, metabolism and behaviors, in Zhejiang Province in 2017 was estimated and compared with those in 1990. Results: High DALY rates of chronic diseases were estimated attributable to tobacco use ( 2 807.08/105 ), unreasonable diet ( 2 724.72/105 ) and hypertension ( 1 878.69/105 ) in Zhejiang Province in 2017, and high DALY rates of chronic diseases were estimated in men attributable to tobacco use ( 4 764.77/105 ), unreasonable diet ( 3 297.00/105 ) and hypertension ( 2 076.92/105 ), while high DALY rates of chronic diseases were estimated in women attributable to unreasonable diet ( 2 117.16/105 ), hypertension ( 1 668.24/105 ) and hyperglycemia ( 1 100.53/105 ), respectively. Among individuals at ages of 15 to 49 years, high DALY rates of chronic diseases were estimated attributable to unreasonable diet ( 759.29/105 ), drug abuse ( 611.71/105 ) and tobacco use ( 605.37/105 ); among individuals at ages of 50 to 69 years, high DALY rates of chronic diseases were estimated attributable to tobacco use ( 5 528.37/105 ), unreasonable diet ( 4 628.18/105 ) and hypertension ( 2 757.78/105 ); and among individuals at ages of 70 years and older, high DALY rates of chronic diseases were estimated attributable to unreasonable diet ( 16 370.09/105 ), tobacco use ( 15 551.40/105 ) and hypertension ( 14 408.63/105 ). As compared to those in 1990, the DALY rates of chronic diseases attributable to high body mass index, alcohol use, hyperglycemia, high low-density lipoprotein cholesterol and drug abuse increased by 108.23%, 48.59%, 23.17%, 17.64% and 6.06%, and the DALY rates of chronic diseases attributable to air pollution, occupational risks, unreasonable diet and impaired renal function reduced by 51.11%, 44.81%, 22.49% and 19.83%, and no significant alterations were detected in DALY rates of chronic diseases attributable to tobacco use or hypertension in 2017. Conclusions There was a high BOD of chronic diseases attributable to tobacco use, unreasonable diet and hypertension in Zhejiang Province in 2017, and the BOD of chronic diseases attributable to high body mass index, alcohol use and hyperglycemia appeared a tendency towards a rise in Zhejiang Province in 2017 relative to in 1990.

Objective To study the epidemiological characteristics of diabetes,and to provide effective prevention and intervention strategies for diabetes in Zhejiang Province.Methods Descriptive epidemiological method was used to analyze the surveillance data of diabetes from 2007 to 2012.Results 272 534 cases of new on-set diabetes were reported through the noncommunicable disease surveillance system in Zhejiang Province from 2007 to 2012,and the annual incidence was 277.08/100 000.According to different types of diabetes,the proportions of type 1,type 2,gestational,and other types diabetes were 0.69％,96.04％,2.23％,and 1.03％,respectively.The incidence was higher in urban and female population.The diabetes incidence was increased with 20.18％ per year and the growing speed of incidence in rural area and males were faster than those in urban area and females,respectively.The incidence in 70-year group was the highest and the growth speed in 20-year group was the fastest one.11.89％ of diabetes patients were diagnosed with complications simultaneously and the proportion of diabetic neuropathy,vasculopathy,and nephropathy was accounted for 82.81％.The incidence of diabetic complications was increased at first and then decreased from 2007 to 2012.Conclusion With the aging trends in Zhejiang province,the incidence will be increased rapidly,and the rural,male,and adolescence populations should be the focus objectives for the diabetes prevention and control in the future.Although the trend of diabetic complications incidence was tended to decline,the result should be confirmed by further researches.

Up to now, there are 11 regions with 16 single nucleotidepolymorphisms in total have been found with GWAS, which provide new ideas for the cause of thyroid cancer and its prevention.

Objective: To understand the underreporting rate of death among residents in Zhejiang Province from 2016 to 2018, so as to provide a basis for improvement of death surveillance measures. Methods: Multi-stage random cluster sampling was used to select residents in 30 public health surveillance areas of Zhejiang Province and all the residents were investigated the general information and death conditions that occurred during the period 2016-2018 by door to door visit. The underreporting rate of death was calculated and descriptive methods were used to analyze the causes of underreporting deaths. Results: A total of 358 992 residents were investigated in 30 public health surveillance areas of Zhejiang Province. There were 63 underreporting deaths among 5 896 deaths, with an underreporting rate of 1.07%. The underreporting rate in men was 1.30%, which was higher than 0.75% in women ( P<0.05 ). The underreporting rate of residents aged 20 to <40 years was 6.74%, the highest among all the age groups ( P<0.05 ). The underreporting rate was 4.46% on the way to the hospital, the highest among all the places of death ( P<0.05 ). The underreporting rate in Wuxing District of Huzhou was 5.80%, the highest among all the surveillance areas. There were 25 cases of "late report or untimely review", accounting for 39.68%; 38 cases of "not report", accounting for 60.32%, of which 14 cases were caused by doctors forgetting to report, accounting for 22.22%. Conclusion The underreporting rate of death in Zhejiang Province from 2016 to 2018 is generally low. In response to underreporting deaths, multi-departmental collaboration should be promoted to effectively strengthen the reporting and management of routine death surveillance.

Objective: To learn the current status of injury among community residents in Zhejiang Province,and to provide reference for injury prevention strategy. Methods: A total of 38 005 residents were recuited from 11 counties or districts in Zhejiang Province by multi-stage cluster random sampling. A retrospective questionnaire survey was conducted to collect their injury occurrence from June 1st of 2017 to May 31st of 2018,then analyzed the incidence,mortality and types of injury. Results: Among 38 005 respondents,2 186 injuries occurred,the incidence rate of injury was 5.75%. The incidence rate of injury in males and females were 5.67% and 5.84%,respectively. The incidence rate of injury in rural respondents（6.97%）was higher than that（4.79%）in urban respondents（P<0.05）. Seven respondents died of injury and the mortality rate was 18.42/100 000. The top five types of injury were falls（2.27%）,traffic accidents（1.53%）,animal bites（0.69%）,sharp articles（0.50%）and blunt articles（0.41%）. The lowest incidence rate of injury lay in 15 to 24 years old,and the highest lay in 65 to 74 years old. The incidence rate of injury increased with age（P<0.05）. The first type of injury in respondents aged 15 to 44 years old was traffic accidents,while others was falls. Conclusion The incidence of injury is higher in rural residents than in urban residents in Zhejiang Province,which increase with age. Falls and traffic accidents are the main threats to residents in Zhejiang Province.

OBJECTIVETo conduct a survival analysis of gastric cancer patients according to the data of population-based cancer registry during 2005-2010 in Zhejiang Province in order to provide information for prognosis assessment and control of this disease.

METHODSThe deadline of the last follow-up of 26, 536 patients was December 31st, 2012. Cumulative observed survival rate (OSR) and expected survival rate were calculated by life table and Hakulinen method.

RESULTSthe 1-, 3-, and 5-year OSR were 58.51%, 39.07%, and 33.08%, and the 1-, 3-, and 5-year relative survival rates (RSR) were 60.24%, 42.90%, and 39.03%, respectively. The 1-, 3-, and 5-year relative survival rates of males vs. females were 60.49% vs. 59.65%, 42.88% vs. 42.96%, and 38.76% vs. 39.64%, respectively, statistically with non-significant differences (χ(2) = 0.13, P > 0.05) between them. The 5-year OSR and RSR of urban patients were 39.15% and 46.30%, and the 5-year OSR and RSR of rural patients were 30.81% and 36.32%, with statistically significant differences between them (P < 0.05). The 15-44 age group had a better relative survival rate.

CONCLUSIONSThe survival rate of gastric cancer patients in Zhejiang Province is low. Work of cancer prevention and control should be strengthened. The wide variation in gastric cancer survival rates between urban and rural patients indicates that priority should be given to rural areas in allocating medical and public health resources.

Objective To describe the survival status and to analyze the factors associated with mortality on first-ever stroke patients.Methods The first-ever stroke patients registered in 2009 were collected from "Zhejiang provincial information system for NCDs' surveillance and management".Survival status and the cause of death through active and passive follow-up programs,were collected.Kaplan-Meier methods were used for survival description.Monovariant and multivariant Cox' s proportional hazard regression models were used to analyze risk factors on mortality.Results A total of 78 189 patients,who suffered from cerebral infarctions (ICD-10:I63),intracerebral haemorrhages (I61),subarachnoid haemorrhages (I60) and unspecified strokes (I64),accounted for 61.65％,30.42％,2.32％ and 5.62％,were recruited.33 265 cases died during the period of this study.27 147 cases were stroke related,accounted for 81.61％.6 122 cases died on the same day,with one-day case fatality as 7.83％ and the overall 28-day case fatality as 21.01％.The survival rates from one-year to four-year were 72.04％,68.92％,66.27％ and 64.29％,respectively.The four-year survival rates of I63,I61,I60 and I64 were 80.06％,50.15％,71.80％ and 21.41％,respectively.Effect of the model showed that the risk factors associated with mortality were age,gender,educational level,the diagnosis and quality of the hospitals on treatment,hypertension and the types of stroke incidences.Age had interacted with gender (P＜0.001).Results from the ‘single effect’ showed that males had higher risk than females in those younger than 75 years old,but vice versa in those older than 75 of age.Conclusion Patients appeared very high risk of death in both acute and sub-acute phases.Factors including age,gender,educational level,both quality on diagnosis and treatment of the hospitals,clinical types of hypertension and stroke etc.were at risk,associated with prognosis of the disease.

OBJECTIVETo provide reference information for prognosis and control of female cancers by analyzing survival rates of breast, cervical and ovarian cancer patients during 2005-2010 in Zhejiang province.

METHODSThe morbidity and mortality data of 18 133 breast, cervical and ovarian cancer patients whose information were registered in health surveillance zone during 2005-2010 in Zhejiang were analyzed. The December 31(st), 2012 was set as the deadline of survival time. Observed survival rate (OS) and relative survival rate (RS) were calculated using SURV3.01 software and comparison between survival rates was conducted through Hakulinen's likely hood ratio test.

RESULTSThe 5-year OS of breast cancer, cervical cancer, and ovarian cancer were 76.89%, 70.79%, 2.59%, respectively during 2005-2010 in Zhejiang province. The 5-year RS of the three cancers were 80.26%, 73.89%, 55.17%, respectively. The 5-year RS of breast cancer, cervical cancer, and ovarian cancer in urban area were 83.11%, 77.87%, and 57.22% and 78.00%, 72.21%, and 53.83% in rural areas, respectively. The overall RS of urban patients was higher than the rural's (χ(2) = 24.98, 11.55 and 6.62, respectively, all P values < 0.05). The 5-year RS of breast cancer, which was grouped by age, showed that the 15-44 years group was the highest (83.40%), while 65-77 years group was the lowest (74.67%). The 5-year RS of cervical cancer decreased with age, with a 41.73% decrease from 83.83% (15-44 years group) to 42.10% ( ≥ 75 years group). The 15-44 years group showed the highest 5-year RS of ovarian cancer (74.30%), while ≥ 75 years group was the lowest (41.80%).

CONCLUSIONThe prognosis of breast cancer and cervical cancer were relatively optimistic, while the ovarian cancer was not. The prognosis of female cancer patients in urban areas were better than in rural areas.

Objective To access the prevalence of type 2 diabetes mellitus ( T2DM) and its associated risk factors among adults with obesity in Zhejiang province. Methods The enrolled subjects were selected among local residents aged≥18 years with body mass index≥28 kg/m2 from 15 counties by multi stage stratified cluster random sampling from July to November, 2010. Each participant was required to attend complete questionnaire, physical examination, and testing overnight fasting blood specimen. Results A total of 1 351 residents were enrolled, including 613 males and 738 females. The prevalence of T2DM in adult population with obesity was 15. 03%, being 14. 03% in male, and 15. 85% in female;and that in urban area was 16. 64%, and in rural area was 13. 93%. Data from multivariable logistic regression showed that factors such as ageing (OR=1. 473, 95% CI 1. 243-1. 747), a family history of T2DM(OR=8. 945, 95% CI 5. 481-14. 598), staple food intake (OR=1. 185, 95% CI 1. 017-1. 380), triglyceride(≥1. 7 mmol/L, OR=1. 542, 95%CI 1. 066-2. 232) were risk factors of T2DM;while annual income(OR=0. 695, 95%CI 0. 544-0. 888), and milk intake(OR=0. 750, 95%CI 0. 567-0. 993) were shown as protective factors. Conclusion The prevalence of T2DM in adults with obesity was raised, ageing, a family history of T2DM, staple food intake, and dyslipidemia appeared to be major risk factors for T2DM.

Objective To evaluate the impact of diabetes prevalence and mortality on health life expectancy (HLE).Methods A cause-excluded health adjusted life expectancy method was used to quantitatively analyze the impact of diabetes on HLE and the composition of health life losses (HLL),using the integrated data on population mortality,self-assessed health status and diabetes prevalence.Results The HLE for people aged 15 was 55.80 in Zhejiang,in 2013.After removing the diabetes morbidity and mortality,the HLE for men aged 15 increased by 0.86 and 1.13,respectively,with an increase of 1.04 and 0.66 for urban and rural residents.Substantial increase of HLE was observed in women and urban residents than those for men and rural residents.HLL caused by diabetes mortality and morbidity appeared as 0.10 and 0.79,with a ratio of 7.92.Conclusion HLL caused by diabetes mortality was much greater than those caused by diabetes mortality,suggesting the most effective measure in reducing the diabetes-related HLL is to promote the healthy lifestyle in urban areas and especially for women.
