To comprehensively evaluate the technical support ability of occupational disease surveillance and evaluation of the county-level Center for Disease Control and Prevention (CDC) in Sichuan Province, in order to optimize the allocation of resources, improve the support ability of occupational disease prevention and control, and provide reference for balanced development.

The technical support ability of occupational disease surveillance and evaluation of county-level CDCs in Sichuan Province was comprehensively evaluated by entropy weight TOPSIS method, followed by classification by RSR method.

Among the 179 county-level CDCs in Sichuan Province, 29 county-level CDCs such as Jiangyou, Mianzhu, and Zhongjiang were rated as “good”, and 28 county-level CDCs such as Shiqu, Batang and Daocheng were rated as “poor”.The rest were rated as “medium”. Kruskal-Wallis H test showed that the grading results were statistically significant (H=120.21, P < 0.001).

The overall level of technical support ability of occupational disease surveillance and evaluation of county-level CDCs in Sichuan Province is not high, and there are great differences among economic zones and within cities (prefectures). In order to achieve an overall improvement and balanced development of technical support capacity for occupational disease monitoring and assessment in county-level CDCs in Sichuan Province, more policy attention should be given, occupational and radiological health technology services certification should be vigorously promoted, targeted training and professional title promotion should be strengthened for specialized talents, and critical instruments should be gradually equipped.

To analyze and summarize the relationship between sleep quality and dietary inflammatory index (DII), so as to provide guidance for improving sleep quality.

Using dietary inflammatory index, anti-inflammatory diet, anti-inflammatory diet, and sleep quality as keywords, China knowledge net, VIP database, Wan fang database, PubMed and Web of Science database were searched, and the related literatures at home and abroad were reviewed to summarize the relationship between DII and sleep quality and its internal mechanism.

There was a correlation between sleep quality and DII, but the conclusion was not consistent. On one hand, pro-inflammatory or anti-inflammatory diet may affect sleep quality by affecting circadian rhythm system and sleep homeostasis. On the other hand, low-quality sleep may affect dietary selection and intake, thus affecting the level of dietary inflammation.

There is a correlation between sleep quality and DII, but there is no consistent conclusion. Larger samples and high-quality studies are needed in order to provide reference for improving sleep quality.

To investigate the relationship between the intake of vegetables and fruits and the composition and diversity ofgut microbiota during the first trimester of pregnancy in Chengdu.

In total 104 early pregnant women in Chengdu were enrolled in this study. Dietary frequency questionnaire was used to collect the intake of vegetables and fruits. According to the median intake of vegetables and fruits, the early pregnant women were divided into high intake group and low intake group. The intestinal microflora of fecal samples of early pregnant women was detected by 16S rRNA highthroughput sequencing, and the differences of intestinal microflora between groups were compared. Multiple linear regression was used to explore the relationship between vegetable and fruit intake and intestinal flora in early pregnant women.

The median intake of vegetables and fruits in early pregnant women was 90.0 g/d and 200.0 g/d, respectively. There was no significant difference in intestinal microflora α and β diversity between high and low intake of vegetables and fruits in early pregnancy. LEfSe analysis showed that the relative abundance of multiple intestinal microflorae in early pregnant women was significantly different between the groups with high and low intake of vegetables and fruits. Multiple linear regression analysis showed that after adjusting age, pre-pregnancy body mass index, and energy intake, early pregnant women’s vegetable intake was directly proportional to the relative abundance of Eubacterium siraeum group (β=0.007, P=0.012), inversely proportional to the relative abundance of Bacteroides (β=-0.167, P=0.023), and fruit intake was proportional to the relative abundance of Ruminococcus gnavus group (β=0.004, P=0.034), inversely proportional to the relative abundance of Agathobacter (β=0.004, P=0.044).

The intake of vegetables and fruits in early pregnancy leads to the change of relative abundance of intestinal flora. This study provides a new scientific basis for dietary regulation of gut microbiota during pregnancy.

To investigate the influence of income level on fertility intention of migrant women in China, and to provide theoretical support for the formulation and implementation of supporting measures to enhance the fertility intention of migrant women.

Based on the survey data of health and family planning of floating population in 2018, the influence of income level on fertility intention of migrant women was analyzed by ologist regression model, and robustness test and heterogeneity test were carried out.

The results of ologist model regression analysis showed that the income level had a significant positive effect on the fertility intention of migrant women (OR=1.182, 95%CI: 1.096-1.274, P < 0.01). The robustness test and heterogeneity test showd that the positive effect of income level remained stable.

Migrant women with higher income levels have higher fertility intention, and income levels have a positive effect on the fertility intention of migrant women.This suggests that a variety of measures including raising the income level on all fronts could be taken to enhance the fertility intention of migrant women.

To understand the prevalence and annual change trend of Internet addiction among students aged 11 and 22 in Inner Mongolia in 2019 and 2021, and to explore the influencing factors of Internet addiction behavior, so as to provide reference basis for the prevention of Internet addiction among students.

Students were selected from 12 cities of Inner Mongolia Autonomous Region by stratified cluster random sampling. Internet addiction disorder was determined according to the items of “surveillance and intervention of common diseases and health influencing factors of students in China”. Logistic regression method was used to analyze the relationship between Internet addiction and behavioral factors.

The prevalence of Internet addiction among students aged 11 to 22 years in Inner Mongolia in 2019 was 1.92%, 2.50%, and 2.21%, respectively. Logistic regression analysis showed that vocational high school (OR=1.347, 95%CI: 1.083-1.675), single parent family (OR=1.279, 95%CI:1.090-1.500), reconstituted family (OR=1.326, 95%CI: 1.041-1.690), bullying (OR=1.755, 95%CI: 1.443-2.135), depression (OR=3.557, 95%CI: 3.146-4.021), fighting (OR=3.374, 95%CI: 2.512-4.531), sugary drinks (OR=2.182. 95%CI:1.753-2.716),and eating fried food (OR=2.398, 95%CI: 1.908-3.014) were the risk factor of Internet addiction. Outdoor activities for 2 hours (OR=0.620, 95%CI: 0.530-0.726), non-smoking (OR=0.553, 95%CI: 0.476-0.643), and non-drinking (OR=0.581, 95%CI:0.507-0.666) were the protective factors of Internet addiction.

The current situation of Internet addiction among students in Inner Mongolia is not optimistic. Attention should be paid to bullying, depression, reconstituted families, fighting students, and vocational high school students. Outdoor activities for 1 to 2 hours a day, reducing the intake of sugary drinks and fried foods, and no smoking and drinking can effectively reduce the incidence of Internet addiction.

To analyze the status of non-response to hepatitis B vaccine and its related factors in children born to mothers infected with hepatitis B virus (HBV).

The children born to mothers with HBV infection reported in Hunan Province from January to December 2022 were selected. All the children received hepatitis B immunoglobulin injection and 3 doses of hepatitis B vaccination and were followed up to 7-12 months of age for detection of hepatitis B surface antigen (HBsAg) and anti-HBs. Both HBsAg and anti-HBs were negative, indicating that there was no response to hepatitis B vaccine in children. Unconditional binary logistic regression model was used to analyze the related factors of non-response to hepatitis B vaccine in children.

A total of 9 792 children born to mothers infected with HBV were analyzed. Among 9 792 children, the non-response rate of hepatitis B vaccine was 9.5% (928/9 792). Non-conditional binary Logistic regression analysis showed that the risk of non-response to hepatitis B vaccine in children born to HBeAg-positive mothers was 1.62 times higher than that in children born to HBeAg-negative mothers (OR=1.62, 95%CI: 1.40-1.88). The risk of non-response to hepatitis B vaccine in children with macrosomia (birth weight ≥ 4 000g) was 1.41 times higher than that in children with normal birth weight (OR=1.41, 95%CI: 1.08-1.85). Maternal antiviral therapy (OR=0.59, 95%CI: 0.48-0.73) and child HepB standard vaccination (OR=0.66, 95%CI: 0.57-0.78) were the protective factors of non-response to hepatitis B vaccine in children.

The non-response rate of hepatitis B vaccine in children born to HBV infected mothers is high, and it is affected by maternal HBeAg positive, antiviral therapy during pregnancy, birth weight, and standard vaccination.

To analyze the mediating effect of sleep duration and sleep quality on physical activity level and cognitive function of elderly residents in rural areas of Chengdu.

By using the method of multi-stage random sampling, subjects over 60 years old were recruited in rural areas of Chengdu in October 2020. A total of 732 subjects were included in this study.A questionnaire survey was conducted by using the physical activity scale for the elderly and telephone interview questionnaire on cognitive status. Linear regression model was used to analyze the effect of physical activity level on cognitive function, and intermediary software package (mediation package) was used to explore the mediating effect of sleep duration and sleep quality.

Physical activity had a positive effect on cognitive function (β=0.004, P<0.0l), and there was a partial mediating effect of sleep duration in the relationship between physical activity and cognitive function in sleep duration (P<0.05). The mediating effect was 0.000 4, accounting for 7.74% of the total effect (0.004 1). There was a partial mediating effect of sleep quality between physical activity and cognitive function (P<0.01). The mediating effect was 0.000 9, accounting for 19.18% of the total effect (0.003 6).

In order to prevent and delay the decline of cognitive function, elderly rural residents should continue to participate in physical activities, and it is necessary to carry out intervention programs aimed at their sleep duration and sleep quality to promote the improvement of their cognitive function.

To analyze the resource allocation efficiency and spatial aggregation of elderly care institutions in China, so as to provide reference for optimizing the elderly care service system.

Three-stage DEA model was used to analyze the resource allocation efficiency of elderly care institutions in 31 provinces (autonomous regions and cities) in 2021. Global Moran’s I index and Getis-Ord Gi* index was used to analyze the spatial autocorrelation of resource allocation efficiency of elderly care institutions in China.

In 2021, the overall scale efficiency of resource allocation of elderly care institutions in China was not high, and there was spatial aggregation effect. Scale efficiency was the main factor restricting the improvement of the allocation efficiency of elderly care institutions in China. The resource allocation efficiency of elderly care institutions was greatly affected by the external environment.

According to the demand of local elderly care service, the government should adjust its scale efficiency reasonably, improve the management level, allocate the resources of elderly care institutions reasonably and promote its efficiency.

To explore the current situation and development trend of coupling coordination between medical and health resource allocation and service utilization in eastern, central, and western regions and provinces of China, and to provide suggestions for promoting the coordinated development of medical and health resource allocation and service utilization.

The related index data of medical and health resource allocation and service utilization from 2018 to 2022 were selected, and the comprehensive development level index and relative development degree were used to evaluate the medical and health resource allocation and service utilization. The coupled coordination degree model was used to analyze the coupling coordination relationship and development trend of the two systems.

There were significant differences in the comprehensive development level of medical and health resource allocation among provinces, and the overall structure of relative development degree in 2021 was “9-11-11”. From 2017 to 2021, the coupling coordination degree of medical and health resource allocation and service utilization decreased, showing a decreasing trend from east to west as a whole. The overall coordination between the allocation of medical and health resources and the utilization of services in China was poor. Only 12 provinces achieved coordinated development in 2021. Xizang was still in the dilemma of serious imbalance.

It is suggested to improve the accuracy of medical and health resources allocation, reduce the differences in the development level of resource allocation between provinces, and build a multi-party co-governance pattern. The improvement strategy of coordination level should be accurately formulated according to the relative development of medical and health resource allocation and service utilization in each province.
