Résumé
@#Injury monitoring is an important approach for injury control and is an important part of comprehensive disease monitoring. With the development of medical digitalization, an intelligent injury monitoring system has been created in Yinzhou District, Ningbo City, Zhejiang Province using artificial intelligence techniques based on Ningbo Municipal Health Information Platform and has been applied across the district since 2019. The manual card-reporting mode has been transformed to intelligent card-reporting mode in this system, which achieves functions of epidemiological analyses of the monitoring data, early warning of high-incidence injuries, classified management of injury and quality control of report cards. Nearly 300 thousand cards have been automatically reported since the system was online available since November 2022, and the epidemiological characteristics of injury were preliminarily understood, which provide data supports to early earning and interventions of injury. The intelligent injury monitoring system greatly improves the injury monitoring efficiency and card-reporting quality, and saves a large number of manpower and material resources, which provides a powerful technical support to widespread injury monitoring.

Objective@#To observe the incidence of unreasonable use of high beam at nighttime among motor vehicle drivers, so as to provide the evidence for the prevention and control of road traffic injury. @*Methods@#Four roads into city and five urban roads were selected in Yongkang of Zhejiang Province. An automatic recording system was used to collect the unreasonable use of high beam among motor vehicle drivers on the selected roads from 19:00 to 5:00 on Monday, Wednesday, Friday and Sunday during a week in July 2020. The regression tree model was used to analyze the relationship of the unreasonable use of high beam with road, time and traffic flow. @*Results@# A total of 89 989 motor vehicles were observed, and 2 419 motor vehicle drivers had unreasonable use of high beam, with an incidence rate of 2.69%. The incidence rate of the unreasonable use of high beam was 3.14% in the roads into city, which was higher than 2.30% in the urban roads ( P<0.05 ). The incidence rates of the unreasonable use of high beam in the roads into city and in the urban roads were 5.15% and 2.90% on Wednesday, which were higher than those on Monday ( 2.89% and 2.34% ), Friday ( 2.90% and 1.92% ) and Sunday (2.06% and 2.12%). The highest incidence rate of the unreasonable use of high beam in the roads into city was 6.07% between 4:00 and 5:00, and in the urban roads was 4.50% between 2:00 and 3:00. The results of regression tree classification analysis showed that the highest incidence rate was 8.13% on the roads into city in the east, west and south directions, and on the urban roads in the east and north directions with less than 317 vehicles per hour on Wednesday. @*Conclusion@#It is more likely for motor vehicle drivers to use high beams unreasonably at nighttime on the roads into city with less traffic flow.

Objective@#To understand the characteristics of different pulmonary function grades and comprehensive assessment groups among patients with chronic obstructive pulmonary disease (COPD) from community survey, so as to provide the evidence for the comprehensive community management of COPD. @*Methods@#The survey data of five monitoring sites in Zhejiang Province during 2014-2015 in the COPD surveillance of Chinese residents aged 40 years and above was collected. The patients with COPD were classified by pulmonary function according to the percentage of forced expiratory volume in the first second (FEV1) in the predicted value, and by comprehensive assessment according to modified British Medical Research Council (mMRC) score, COPD Assessment Test (CAT) score and acute exacerbation in the past year. The characteristics of different pulmonary function grading and comprehensive assessment groups were compared. @*Results@#A total of 355 patients with COPD were found, with an average age of (63.00±9.63) years. The male-to-female ratio was 3.18:1. There were 243 patients with an education level of primary school or below, accounting for 68.45%. The awareness rate of COPD related knowledge was only 1.69%. There were 257 (72.39%) patients with mild, 86 (24.23%) patients with moderate, and 12 (3.38%) patients with severe pulmonary function. The proportions of patients with childhood history of severe respiratory infection, self-reported respiratory system diseases, chronic cough, chronic sputum, acute exacerbation in the past year, CAT score ≥10 points, and inhaled medication were lower in the patients with mild pulmonary function than with moderate and severe pulmonary function; the body mass index and waist circumference were higher in the patients with mild pulmonary function than in the patients with moderate and severe pulmonary function (all P<0.05). The comprehensive assessment resulted in 158 (44.51%) patients of Group A, 134 (37.75%) patients of Group B, 1 (0.28%) patient of Group C, and 7 (1.97%) patients of Group D. The average age and systolic pressure were lower in Group A than in Group B, C and D; the proportions of patients with self-reported respiratory system diseases, family history of respiratory diseases, chronic cough, chronic sputum, dyspnea, acute exacerbation in the past year and CAT score ≥10 points were lower in Group A than in Group B, C and D (all P<0.05). @*Conclusion@#The community patients with COPD are mainly classified to mild pulmonary function and Group A in the comprehensive assessment; thus they need different levels of management.

Objective @#To explore the relationship between alcohol consumption and hypertension in adults of Zhejiang Province, so as to provide scientific evidence for the prevention and control of hypertension. @*Methods@#Data were collected from 10 national surveillance sites in Zhejiang Province in the 2018 China Chronic Disease and Risk Factors Surveillance. The multivariate logistic regression model was used to explore the relationship between alcohol consumption and hypertension in adults of Zhejiang Province. @*Results @#Among 5 908 people included, 2 641 were males, accounting for 50.38%; and 3 267 were females, accounting for 49.62%. There were 2 721 cases of hypertension ( 28.54% ). The number of the cases with no, light and excessive alcohol consumption was 3 945, 1 117 and 846, accounting for 66.28%, 23.65% and 10.07%, respectively, after complex sampling weighting. The results of the multivariate logistic regression model showed that compared with those with no alcohol consumption, the adults with excessive alcohol consumption had higher risk of hypertension ( OR=2.126, 95%CI: 1.649-2.741 ); men with light ( OR=1.875, 95%CI: 1.075-3.270 ) and excessive alcohol consumption ( OR=2.752, 95%CI: 2.021-3.748 ) had higher risk of hypertension; the 18-<45-year-old adults with light ( OR=2.441, 95%CI: 1.171-5.087 ) and excessive alcohol consumption ( OR=3.368, 95%CI: 1.609-7.049 ), and the ≥60-year-old adults with excessive alcohol consumption ( OR=1.632, 95%CI: 1.174-2.269 ) had higher risk of hypertension. @*Conclusions @#Light and excessive alcohol consumption are associated with hypertension in Zhejiang adults. The association is stronger between excessive alcohol consumption and hypertension than between light alcohol consumption and hypertension.
