    Objective

    To analyze the spatial compatibility between maternal and child health beds and the needs of women and children in Jiangsu at the county scale.

    Methods

    Spatial autocorrelation was used to analyze the spatial distribution of bed resources and maternal and child population in maternal and child health institutions in Jiangsu Province, and the adaptability of bed resources to the supply and demand of maternal and child population was analyzed by clustering degree.

    Results

    The population of women and children of childbearing age showed obvious spatial aggregation in all districts and counties of Jiangsu Province, mainly concentrated in Suzhou and Xuzhou.There were 122 maternal and child health care institutions in Jiangsu, including 12 tertiary institutions and 29 secondary institutions, with a total of 11 878 beds. It was worth noting that there were 41 districts and counties with 0 beds, of which Suzhou City accounts for 7 districts and counties. The number of beds per 1 000 women and children in Zhonglou District of Changzhou City was the highest, 2.7 per 1 000 women and children. From the perspective of concentration degree, the bed resources of 17 districts (17.89%) were adequate geographically, while those of 76 districts (80%) were scarce geographically.After considering the demand population, it was found that the supply was greater than the demand in 21 districts (22.11%) and that the supply was less than the demand in 74 districts (77.89%).

    Conclusion

    There are regional differences in the supply and demand adaptation of maternal and child health care resources in Jiangsu Province, so it is necessary to adjust the service scope of the region where the supply exceeds the demand, and increase the service capacity building.

    Objective

    To assess the disease burden of migraine in China from 1990 to 2019 and predict the changing trends in disease burden from 2020 to 2030, which may provide reliable data support for public health decision-making.

    Methods

    The study utilized data from the Global Burden of Disease 2019 (GBD2019) database and analyzed the age-standardized incidence rate (ASIR) and age-standardized DALY rate of migraine in China from 1990 to 2019. Estimation of annual percentage change (EAPC) models and Bayesian age-period-cohort (BAPC) analysis methods were employed to reveal changes and trends.

    Results

    From 1990 to 2019, both the ASIR and age-standardized DALY rate of migraine in China showed an upward trend, with EAPCs of 0.24% (95%CI: 0.20%-0.29%) and 0.27% (95%CI: 0.22%-0.32%), respectively. The highest ASIR for migraine was observed in the age group of 10-15 years, followed by a fluctuating decline, and then an increase in ASIR in the 25-30 age group. The age-standardized DALY rate peaked in the 40-45 age group. Disease burden indicators for females exceeded those for males during the same period. According to the BAPC model predictions, the ASIR for migraine in the entire population of China was expected to increase from 2020 to 2030, with an annual growth rate of 0.88%. The annual growth rates of ASIR for males and females were projected to be 1.21% and 0.64%, respectively.

    Conclusion

    The burden of migraine in China remains quite severe, and there should be a focus on adolescents and young to middle-aged populations. Customized prevention and intervention strategies are crucial for high-risk populations of different ages and genders.

    Objective

    To investigate the pollution status of lead, cadmium, total mercury, total arsenic, total chromium, manganese, nickel, aluminum, copper on sale vegetables in Taizhou City, and to assess the health risks to people.

    Methods

    According to the requirements of relevant national standards, detect the contents of metals and metalloids in four types of commercial vegetable samples collected from 2019 to 2023. The pollution status evaluated by single factor pollution index (Pi) and Nemerow composite pollution index (PM) method, the health risks were evaluated by both target hazard quotient (THQ)and total target hazard quotient (TTHQ).

    Results

    A total of 419 samples of four types of vegetables were collected, manganese and copper had the highest detection rate with both of 100.0%, the others from high to low were nickel (89.17%)>aluminum (87.26%)>cadmium (85.20%)>total arsenic (52.03%)>lead (35.32%)>total chromium (30.55%)>total mercury (2.39%). The overall cadmium exceeding rate was 2.63% and all concentrated in root vegetables, the other elements did not exceed the limit. The Pi and PM of lead, cadmium, total mercury, total arsenic, total chromium in different types of vegetables were all did not exceed 0.7. The TTHQ of four types of vegetables for adults were all less than 1.0, but the TTHQ were more than 1.0 while children consumed root and leafy vegetables.

    Conclusion

    The overall pollution levels of nine metals and metalloids in four categories of vegetables in Taizhou city were low, and the health risk level of these metals and metalloids in residents was acceptable. However, intake of root and leafy vegetables may have negative effects on human health in children.

    Objective

    To understand the trends and factors associated with newly reported HIV and syphilis infections among men who have sex with men (MSM) in Nanning city, and provide a reference for developing targeted prevention strategies for the MSM population.

    Methods

    A questionnaire survey was conducted among MSM people in Nanning, Guangxi from 2019 to 2023, and venous blood samples were collected to detect HIV, HCV and syphilis. The trend chi-square test was used to analyze the trends of newly reported HIV,syphilis, and self-reported sexually transmitted infections prevalence. Logistic regression was employed to identify factors associated with newly reported HIV and syphilis infection.

    Results

    A total of 1,954 MSM participated in the survey. The prevalence of newly reported HIV and syphilis were 3.8% and 4.6%. Respectively, there was a significant decline in newly reported HIV prevalence, from 6.8% in 2019 to 2.5% in 2023 (,trend P<0.05), while newly reported syphilis prevalence increased from 1.8% to 11.1% during the same period (, trend P<0.05). The study identified several factors associated with newly reported HIV infection, including lower education levels (aOR=1.70,95%CI:1.04-2.77) and inconsistent condoms use during anal intercourse (aOR=10.11, 95%CI: 5.94-16.89). Lower education levels (aOR=2.74, 95%CI: 1.71-4.38), a history of drug use (aOR=6.96, 95%CI: 1.42-34.19), and a history of self-reported sexually transmitted diseases (aOR=10.37, 95%CI:5.79-19.89) were found to be associated with newly reported syphilis infection. aged ≥30 (aOR=0.50, 95%CI:0.31-0.81)was identified as a protective factor against syphilis infection.

    Conclusion

    The prevalence of newly reported HIV was a downward trend, but the trend of newly reported syphilis prevalence showed an upward trend among MSM in Nanning, 2019-2023. The study suggests that relevant health departments need to take targeted intervention measures for the MSM population in conjunction with the internet, improve the usage rate of condoms, and strengthen the regulation of drugs and pharmaceuticals.

    Objective

    To explore the impact of cultural activities (CA) and physical exercise (PE) on residents’ subjective well-being (SWB)and its mechanism.

    Methods

    Using the 2021 China Comprehensive Social Surveydata, the ordered logistic model and mediating effect model were used for empirical analysis.

    Results

    CA and PE could significantly enhance residents’ SWB, and the effect of CA on enhancing SWB was greater than that of PE. CA had a relatively greater impact on SWB of women, elderly, and rural residents. PE had a relatively greater impact on SWB of young and urban residents. Health status, social networks, social trust and sense of fairness all played a mediating role in the relationship between CA and SWB. Social trust had the greatest mediating effect, followed by health status, social networks and sense of fairness. Health status, social networks, social trust and sense of fairness all played a mediating role in the relationship between PE and SWB. Health status had the greatest mediating effect, followed by social trust, social networks and sense of fairness.

    Conclusion

    The government should strengthen efforts to promote the development of culture and sports industry, so that the people can get better spiritual and cultural nourishment and physical and mental health improvement, and have bigger SWB.

    Objective

    To analyze the epidemiological characteristics, spatial clustering, and influencing factors of tuberculosis recurrence in Kashgar within three years after successful treatment to provide a scientific basis for tuberculosis recurrence management.

    Methods

    Taking the tuberculosis patients successfully treated in Kashgar from 2013 to 2020 as the research object, we observed the recurrence epidemic characteristics, conducted spatial analysis to understand the recurrence clustering, and used the Cox regression model to explore the influencing factors.

    Results

    Among the 104 899 objects,14 180 experienced recurrences within three years, with a cumulative recurrence rate of 13.52%. Spatial analysis showed a positive spatial correlation of tuberculosis recurrence, with recurrence hotspots mainly concentrated in Shache, Yingjisha, and Bachu counties. The Cox model showed that male (aHR=1.155, 95%CI: 1.118-1.195), Uyghur (aHR=2.186, 95%CI: 1.786-2.681), 45-<60 age groups (aHR=1.631, 95%CI: 1.061-2.507) and ≥60 age groups (aHR=1.782, 95%CI: 1.160-2.738), farmers and herdsmen (aHR=1.104, 95%CI: 1.039-1.173), re-treatment (aHR=1.086, 95%CI: 1.036-1.138), positive aetiology result (aHR=1.377, 95%CI: 1.324-1.432), positive sputum smear after two months of treatment (aHR=1.699, 95%CI: 1.501-1.924), total delay ≥30 days (aHR=1.129, 95%CI: 1.088-1.171) and living in hotspots (aHR=1.470, 95%CI: 1.413-1.530) were independent risk factors for recurrence after successful treatment.

    Conclusion

    Priority should be given to improving the monitoring and management of patients in hotspot regions and those at high risk of relapse after treatment to ensure early detection of TB relapse and standardized care.

    Objective

    To analyze the non-occupational carbon monoxide (CO) poisoning incidents in Jinan City from 2011 to 2022, to grasp their epidemiological characteristics, and propose suggestions for further reducing the morbidity and mortality of non-occupational CO poisoning.

    Methods

    Descriptive epidemiological method was used to analyze the data. The chi-square test was used to compare the rates.

    Results

    From 2011 to 2022, Jinan City reported 3 003 incidents of non-occupational CO poisoning, with 4 208 cases of poisoning. The average number of poisoning cases per year was 351, with the population over 60 years old being the high-risk group for poisoning. There was a total of 125 deaths, with a fatality rate of 2.97%. The mortality rate of critically ill patients was significantly higher than that of other groups (χ2=45.54, P<0.001). The average annual incidence of non-occupational CO poisoning was 47.48 per million, and the average annual mortality rate was 1.18 per million. The date of occurrence of non-occupational CO poisoning in Jinan City had obvious seasonal characteristics, which was consistent with the winter and spring heating seasons. Among poisoning incidents with clear causes, improper heating was a major cause of poisoning (2 554, 87.4%), followed by gas leaks (207, 7.1%), and the consumption of charcoal hot pots and other charcoal-grilled foods (113, 3.9%).

    Conclusion

    Although the incidence of non-occupational CO poisoning in Jinan is on a downward trend, the number of people poisoned is still high, and the causes of poisoning are diverse. Therefore it is necessary for multiple departments to jointly carry out the corresponding inspection and preventive work while strengthening the safety education for the residents.

    Objective

    To understand the air pollution level, to analyze the source apportionment of metals and metalloids in PM2.5 and to evaluate its health risk in the city of Hefei.

    Methods

    The concentration of 10 elements (As,Cd,Cr,Ni,Pb, Mn,Se, Al and Sb)in PM2.5 samples was collected in Hefei city from January 2018 to December 2022, which was used to analyze the pollution level and source apportionment was determined by inductively coupled plasma mass spectrometer(ICP-MS). Correlation analysis, principal components analysis and cluster analysis were used to analyze the sources of metals and metalloids. A health risk assessment model was used to evaluate the health risk of population of 4 carcinogenic elements(As,Cd,Cr,Ni) and 5 non-carcinogenicelements(Pb,Mn,Se,Al,Sb).

    Results

    The total average concentration of 10 elements in PM2.5 was in an order of Al>Pb>Mn>As>Se>Sb>Ni>Cr>Cd>Tl and presented an obvious seasonal variation characteristic, higher in winter and spring, lower in summer and autumn.The mixed sources of coal burning, traffic and industry, dust and industrial emissions sources were the main sources of metals and metalloids in ambient PM2.5 in Hefei.The respiratory pathway exposures of these elements assessed by annual excess risk were between 1.67×10-7and 4.22×10-15, which were below the acceptable risk level of population (10-6).

    Conclusion

    The main sources of metals in Hefei are mixed sources, soil dust sources and industrial sources. The respiratory pathway exposures of most of the elements assessed by annual excess risk are below the acceptable risk level of population.

    Objective

    To explore the relationship between lifestyle and depression symptoms among college students.

    Methods

    A total of 21 143 college students from a private university in Shaanxi province were selected to conduct an online questionnaire survey, including social demographic characteristics, lifestyle and depression symptoms. GAMMA regression and Logistic regression models were used to analyze the association between five lifestyle and unhealthy lifestyle scores and depression symptoms in college students.

    Results

    The depression symptom score of college students was 29(22,36), and the prevalence of depression symptoms was 15.57%. The prevalence of smoking, drinking, unhealthy diet, lack of physical activity, low body weight or obesity were 17.98%, 24.24%, 83.45%, 80.11% and 46.63%, respectively. The five unhealthy lifestyles were significantly correlated with depression symptoms of college students (all P<0.05). Regression analysis showed that, compared with the unhealthy lifestyle scores of 0-1, the score of depression symptoms increased in the group with 3, 4 and 5 score of unhealthy lifestyle, with β(95%CI) values of 0.57(0.23-0.92), 1.91(1.48-2.34) and 2.47(1.79-3.15), respectively. Compared with the unhealthy lifestyle scores of 0-1, the risk of depression symptoms was increased in unhealthy lifestyle scores of 2, 3, 4 and 5, and the odds ratio value (95%CI) were 1.19(1.02-1.40), 1.41(1.21-1.65), 1.86(1.56-2.21) and 2.18(1.71-2.78), respectively.

    Conclusion

    Unhealthy lifestyle is related to the increased risk of depression symptoms in college students. The more types of unhealthy lifestyle, the higher the score of depression symptoms and the higher the risk of depression symptoms.
