HbA1c control should be given a high priority among men living in low-economic-level regions with long course of disease, use of hypoglycemic drugs, chronic complications, smoking, uncontrolled blood pressure and lipid.
ABSTRACT
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.
ABSTRACT
Objective@#To learn the status of knowledge,attitude and behaviors of road traffic safety in primary and secondary school students in Xiacheng District of Hangzhou. @*Methods@#The students of fourth to seventh grade from seven schools in Xiacheng District were selected and surveyed for their knowledge,attitude and behaviors of road traffic safety by self-designed questionnaires. @*Results@#Totally 4 006（99.98%）students completed the survey,who mostly had awareness rates of over 90% in knowledge about safe behaviors when walking,walking across the road and riding a bicycle or an electric bicycle. The awareness rates of"should not run across the road","should not ride side by side"and"should not ride on the motorway"were relatively low,which were 81.65%,85.72% and 82.78%,respectively. About 68.47% of students thought it necessary to wear a helmet when riding a bicycle or an electric bicycle,72.22% of students thought it necessary to wear seatbelt or use child safety seat when taking a car. The two rates were significantly higher in girls than boys and in primary school students than secondary school students（P<0.05）. The top three unsafe behaviors the students did in the past six months were"not wear a helmet when riding a bicycle or an electric bicycle","run across the road"and"ride on the motorway",the rates of which were 86.84%,10.06% and 7.91%,respectively. @*Conclusion@#The knowledge of road traffic safety among primary and middle school students in Xiacheng District is mastered well. Interventions should be focused on unsafe behaviors including not wearing a helmet when cycling,riding on the motorway and running cross the road.

ABSTRACT
Objective To identify precipitating factors of a tuberculosis (TB) outbreak in a school and discuss the importance of index case detection on outbreak monitoring,follow up and related control measures.Methods A case survey of the index patient was conducted to evaluate the illness severity and infectious duration of the case.The initial response to this case was surveyed to understand the factors leading to the outbreak.Results A total of 25 TB cases were detected in the outbreak,including 14 cases in one class.The risk of catching TB among the classmates of the index case was 10.74 times higher than that among students in other classes (x2=42.31,P＜0.001).Although the index case had typical TB symptom of cough and expectoration,TB was not diagnosed until pulmonary cavity was detected by chest radiograph one month later.Among 64 close contacts,56 (87.5％) completed TB screening,52 (92.9％) were purified protein derivative positive.No TB cases were detected.Conclusion The factors leading to the outbreak included delayed diagnoses of the index case,no chemoprophylaxis taken by the close contacts; poor surveillance and follow-up for close contacts.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the association between sleep duration and stroke in adults.</p><p><b>METHODS</b>Baseline data of 57 704 subjects who were aged 30-79 years and enrolled into China Kadoorie Biobank (CKB) study from Tongxiang county, Zhejiang province were analyzed. Multiple logistic regression analysis was conducted to investigate the putative association between sleep duration and stroke after adjusting for potential confounders.</p><p><b>RESULTS</b>The mean age of the subjects was (53.15 ± 10.20) years in males and (51.72 ± .69) years in females, respectively. There were 14.43% of males and 15.30% of females reporting sleep durations ≤ 6 hours per day and 5.39% of males and 5.95% of females reporting long duration of sleep (≥ 10 hours per day). The prevalence of stroke was 0.92% in males compared with 0.44% in females. The prevalence of stroke showed a U-shaped distribution with sleep duration. Compared with 7 hours sleep duration per day, long sleep duration (≥ 10 hours per day) was associated with stroke. The odds ratios (OR) were 2.11 (95%CI: 1.32-3.37) for males and 2.13 (95%CI: 1.24-3.65) for females after adjusting for age, socioeconomic status, health behaviors and health status. No statistical significant association was found between short sleep duration and stroke. Meanwhile, frequent sleep snoring was found to be associated with stroke in females (OR=1.63, 95% CI: 1.11-2.40).</p><p><b>CONCLUSION</b>Longer sleep duration was found to be associated with higher risk of stroke in both males and females. Frequent sleep snoring would increase the risk of stroke in females.</p>
