Based on the intersection of“Implementing the National Strategy to Actively Cope with Population Aging”and“Guiding Opinions on Future Rural Construction”in Zhejiang Province,this study constructed the evaluation index system of rural age-appropriate building space.This is done by analyzing the current situation locally and internationally,summarizing the existing problems,and optimizing countermeasures.The cross-analysis method is adopted by fully listening to the opinions of the elderly and introducing a professional team to transform the physical,psychological,and rural natural environment of the elderly.The renovation strategies of building layout,indoor and outdoor space,and supporting facilities for the elderly are put forward.Looking to the future,including the application of intelligent technology,the development of a community pension model,and multi-party cooperation,it aims to create a comfortable,safe,and convenient living environment for rural elderly people,improve the quality of life,promote rural revitalization and actively respond to the challenges of population aging.

Spatial Coupling Relationship and Driving Mechanism of Population and Economy in Rural Areas in Qinling-Daba Mountains,China

Addressing the issue of the healthy and coordinated development of the population and economic factors in rural areas will not only help consolidate and expand the achievements of poverty alleviation,but will also lay a foundation for comprehensive rural revitalization.In this paper,the spatial coupling relationship between the population and economic factors in rural areas in the QinlingDaba Mountains,China,is explored to provide a reference for rural revitalization and regional sustainable development in poverty areas.Sixty-eight county units in rural areas in the Qinling-Daba Mountains,as well as the population and economic factors in rural areas,are used to study the spatial coupling relationship between population and economy,as well as the driving mechanism,in rural areas in the Qinling-Daba Mountains from 2010 to 2020.The results show that a population contraction phenomenon occurred in the rural areas in the Qinling-Daba Mountains,and the spatial agglomeration trends of the population and economic factors were consistent.The agglomeration was mainly located in the suburban areas of the municipal area,and the agglomeration degree was significantly higher in these areas than in other areas.In terms of the spatial distribution,the economic development level of the rural areas in the northeastern part of the Qinling-Daba Mountains was generally higher than that in the central and western parts,and the unbalanced trends of the population and economic spatial differentiation in the eastern and western regions were significant.The spatial coupling relationship between the population and economy changed from coordinated development to economic advancement.This was mainly due to the mutual restriction and joint actions of the industrial structure,capital situation,natural environment,policies,and institutional regulations,among which the industrial structure and capital status had significant effects.

Identifying the Static and Dynamic Relationships Between Rural Population and Settlements in Jiangsu Province, China

Rapid urbanization has triggered large rural population floating into cities, which in turn affects rural human-land relationships. The actual human-land relationship involves the coupling level of a time point and dynamic change of a time interval. However, few studies have identified the rural human-land relationship from these two perspectives. This study combined static coupling analysis with a dynamic decoupling model to analyze the relationships between rural population and settlements from 2009 to 2018 in Jiangsu Province, China. Although the static coupling degree in Jiangsu Province was relatively high, the decoupling analysis found that the rural human-land relationship in most counties was uncoordinated. There were 11 combination types based on the coupling and decoupling relationships. The most common two types(accounting for 76.74%) were recession decoupling with high-level coupling and strong decoupling with high-level coupling. Although the majority of counties had a high-level coupling degree, an uncoordinated change in rural population and rural settlements was observed in these counties. Counties with relatively reasonable human-land relationships accounted for only 12.79% of the total. The combination features for each type were identified and differential policies were proposed for optimizing human-land relationship in rural areas. This study would contribute to our understanding of the multiple relationships between rural population and settlements involved in different patterns and processes, and expect to provide theoretical and methodological support for promoting rural revitalization and sustainable development in practice.

Selection model of trip time for rural population

Referring to the 1 248 survey data of rural population in 14 provinces of China, the influencing factors of trip time choice were analyzed. Based on the basic theory of disaggregate model and its modelling method, nine grades were selected as the alternatives of trip time, the variables affecting time choice and the method getting their values were determined, and a multinomial logit (MNL) model was developed. Another 1 200 trip data of rural population were selected to testify the model's validity. The result shows that the maximum absolute error of each period between calculated value and statistic is 3.6%, so MNL model has high calculation accuracy.

Polymorphisms in CYP2R1 Gene Associated with Serum Vitamin D Levels and Status in a Chinese Rural Population

Vitamin D, a fat-soluble vitamin and endocrine horm one, and it impacts various bone and extra-bone health, such as osteoporosis, diabetes, and cancer. The main circulating form of vitamin D is 25-hydroxyvitamin D [25(OH)D] and it is a useful clinical biomarker of vitamin D status. The Institute of Medicine (IOM) defines as vitamin D deficiency (VDD) when serum 25(OH)D concentration is less than 20 ng/mL⑴.Worldwide, VDD is recognized as a severe public health problem. In 2007, Holick estimated that globally over one billion people suffered from VDD or vitamin D insufficiency (VDI). In China, it has bee n reported that the prevale nee of VDD ranged from 38.8% to 91.2% in different regions.

Periodontal conditions and treatment in urban and rural population of West Bengal,India

Objective:To search adequate epidemiological data on periodontal conditions for the planning of oral health programs in Indian population,and to determine the prevalence of periodontal diseases,in regards to age and gender of urban and rural population in West Bengal.India. Methods:22 542 subjects aged 15 years onwards,representative of rural and urban areas of West Bengal were examined for their periodontal conditions using the community periodontal index(CPI).Results:Supra and/or sub gingival calculus dominated as the most frequent score (score 2) among males(76.51%) and females(76.58%),which was least affected in young age group and higher in rural population.Severity of highest score were significant(P【0.001) according to their gender,age group and habitation and had independent effects(P【0.001) on it. Mean number of sextants affected by scores 1,2,3,& 4 were more in the rural areas.Assessed treatment needed was predominantly typeⅡ(Scaling and improved oral hygiene).Conclusions: The severe periodontal condition(Score 2,3 and 4) is observed among rural males in older age group more than its urban counterparts of West Bengal,India.

Sero-Prevalence of <i>H. pylori</i>Antibodies among Asymptomatic Rural Population in Bauchi State, Nigeria—A Preliminary Study

Helicobacter pylori infection is a major public health problem globally, with high prevalence in developing countries associated with poor sanitation, low standard of living, urban-rural disparity and increased gastrointestinal pathologies. This preliminary study determined the seroprevalence of H. pylori infection among asymptomatic rural population and association of sociodemographic variables on the result outcome. A total of 250 asymptomatic volunteered participants were screened for H. pylori antibodies, using rapid immunochromatographic strips. 44.8% (112/250) were seropositive, and showed increased prevalence with the age group, <15 years (8.0%), 18 - 39 years (23.5%) and 40 - 65 years (12.0%) with no significant difference. High prevalence among males, 88 (35.2) compared to 24 (9.6) females (p < 0.228). Significant association was observed with marital status, high prevalence among married participants 63 (25.0) followed by singles, 41 (16.4) (p < 0.010). Similarly, significant prevalence was observed among participants with non-formal education, 60 (24.0) followed by primary education, 21 (8.4) (p < 0.51). While non-salary earners accounted for 79 (31.6) (p < 0.244). The H. pylori seropositivity of 44.8% is relatively low in region with previous reports of high prevalence and predisposing risk factors. Further studies are needed to evaluate the effect of environmental and occupational risk factors for better epidemiological understanding of H. pylori infection and a template for intervention measures.

Severity and Magnitude of Caries among Rural Populations in Ferlo in Senegal

Oral diseases belong to non-communicable diseases. They are characterized by their importance especially in disadvantaged areas. The objective of this study was to measure the extent and severity of caries among rural populations of Widou, an area located in central Ferlo. It was a descriptive and cross-sectional study which involved 300 individuals selected using simple random sampling. The socio-demographic characteristics collected were sex, age, educational level and occupation. The dental status was rated by the prevalence of dental caries and DMF and its components. The data were analyzed with the software Epi info 3.4.5 with 5% of threshold statistical significance. The prevalence of dental caries was 89%. The mean DMF was 5.4 ± 5.6 with a maximum of 26. The mean of component “D” was 3.8 with a maximum of 24. Variables significantly associated with dental caries were sex (p = 0.012) and occupation (p = 0.03). The extent and severity of caries in rural areas of the Ferlo evoke a relatively low support or management and require efforts in prevention, directed on oral hygiene and dietary habits.

Analysis of Rural Population Planning in Liaoning Based on Push and Pull Theory

Data from the seventh national census show that the mobility of rural population in Liaoning is relatively active.Rural revitalization,as a major deployment for development in the new era,will undoubtedly face a variety of problems in the implementation process.Through the study of the relationship between rural revitalization and population,it is found that the loss of rural population is one of the important reasons that hinder rural economic development and lead to the imbalance of urban and rural economic development.According to the "push and pull theory" by the demographer Bagne,the paper analyzes the causes of rural population loss in Liaoning Province.The rural population backflow and two-way flow of urban and rural population in Liaoning Province is achieved through industrial interaction between urban and rural areas,innovative development of agriculture,steady follow-up of service industry and other measures,thus revitalizing the rural economy.

Urban Rural Disparity in Westernization Related Cancers and the Increasing Incidence in Parallel with Socioeconomic Development and Urbanization from 2000-2015 among a Rural Chinese Population: An Observational Study

Abstract China used to have great urban rural disparity in socioeconomic development. Since the late 1980s, rapid socioeconomic development and urbanization have been taking place in rural settings. It is epidemiologically established that cancer scale and profile will transit as economy prospers and urbanization develops. However, there are few published studies reporting what changes are undergoing in cancer pattern in Chinese rural settings. Population-based tumor registration data collected by us in urban Shijiazhuang city (available for 2,374,827 people in 2012) and in rural Shexian County (available for 408,995 people since 2000) were used for urban rural comparison of age standardized incidence rate (ASIR) of westernization-related cancers in 2012, and the trend of biennial ASIR of these cancers for 2000-2015 in Shexian County was examined following a decade of rapid socioeconomic development and urbanization. From 1988-2015, the Gross Domestic Product per Capita (GDP) in rural Shexian County increased from 860 to 3000 US$, and urbanization rate from 22.4% to 54.8%. The biennial ASIRs of lung, colorectal, gallbladder cancer and leukemia in both sexes, and that of breast, ovary, thyroid, and kidney cancer in women increased significantly from 2000 - 2015. The increase from 2000-2001 to 2014-2015 in man and women for lung cancer was from 15.9 to 34.7 per 105 (P = 0.05) and 9.6 to 16.7 (P = 0.00), for colorectal cancer from 6.6 to 15.9 (P = 0.00) and 4.0 to 11.7 (P = 0.00), for gallbladder cancer from 0.1 to 2.4 (P = 0.00) and 0.3 to 2.7 (P = 0.00), for leukemia from 2.8 to 7.7 (P = 0.00) and 2.3 to 6.2 (P = 0.00);and in women for cancer of breast from 2.8 to 17.3 (P = 0.00), kidney from 0.2 to 2.4 (P = 0.00), ovary from 0.2 to 4.3 (P = 0.00), and thyroid from 0.2 to 4.2 (P = 0.00). Notwithstanding these increases, their ASIRs in 2012 in Shexian County were still significantly lower than that in Shijiazhuang city. Westernization-related cancer is increasing rapidly in rural China. Comprehensive measures are needed to strengthen prevention to ensure sustainable development.

Topographic and lithologic controls behind mountain depopulation in Zlatibor District(Western Serbia)

Mountain depopulation is a worldwide phenomenon observed in all continents. It has varied socio-economic reasons;among others, the low profitability of traditional agriculture, the better job possibilities and the higher level of services in urban settlements. However, it is often recognized that depopulation is related to natural factors such as elevation, slope or lithology. It is also observed that protected areas are frequently established in depopulated mountain regions. Their primary aim is the conservation of nature, but they may help tourism development as well. Tourism, in turn, may slow down or even reverse the process of depopulation. In this study, we investigate the impact of topographic and lithologic factors, namely of karst settings, on mountain demographic processes and the relationship of protected areas and tourism through the example of the northern part of Zlatibor District(Western Serbia). The study area is characterized by mountains and hills at elevations from 200 to 1600 m a.s.l. Our aim is to find GIS-based statistical relationships between topographic, lithologic factors and demographic characteristics. In this area, mountain depopulation started after WWII, and weproved that this process was strongly controlled by topographic factors. The higher and more dissected the area, the more significant is the decrease of the population and the more advanced is the ageing. As a result, population density contrasts are much more pronounced now than 70 years ago. After WWII, depopulation and ageing became gradually more serious on karstic terrains than on non-karst. However, by using compound topographic and lithologic types, we proved that it is not the effect of karst, but the effect of topography. The flow of population from hills and mountains to valleys and basins are closely related to the restructuring of the economic sectors. At present, for the study area, the development of tourism is unequivocally naturebased and connected to protected areas, namely to Tara National Park, Zlatibor Nature Park and ?argan–Mokra Gora Nature Park. In this paper, we also demonstrate how lithology influences tourism possibilities. The leading role of Zlatibor in tourism development is largely thanks to its favourable position on a main transit route.

POPULATION MOVEMENT AND THE CHANGE OF REGIONAL ECONOMY PATTERN

Population movement is an important phenomenon in China in recent years. Its mechanism is: (1) thrust of more people and less land in the eastern region of China; (2) attraction of dual economy in the western region of China; (3) national policy on preferential wages and grains for the western region. Population movement has an important effect on the change of regional division pattern in China: by the medium of the moving people, there forms another regional division pattern, i.e. rural industry system based on rural town industry; (2) there forms another profit mechanism compensated from the western region to the eastern region. It not only wins more profit in the eastern region, but also changes dual economy in the western region. Therefore, We should make choice of a comprehensible and encouraging attitude on population movement; a special government organization for general survey of the moving people should be set up at once.

Enterobius vermicularis infection among population of General Mansilla,Argentina

AIM:To evaluate the relationships between the personal, sociocultural,and environmental characteristics,and the presence or absence of symptoms with the detection of Enterobius vermicularis(E.vermicularis)in a population sample in our region(General Mansilla,Province of Buenos Aires,Argentina),by individual and familiar analyses. METHODS:E.verrnicularis was diagnosed in 309 people from 70 family units residing in the urban area and the rural area of the city of General Mansilla.Each of them was surveyed so as to register personal,environmental and sociocultural data.Questions about the presence or absence of anal itch,abdominal pain and sleeping disorder were also asked.Significant associations were determined by square chi tests.Logistic regression models were adjusted by using a backward conditional stepwise method to determine the presence of this parasite in the individuals and in the families. RESULTS:The parasites were found in 29.12%(90/309) of the individuals,with a frequency of 14.28%(20/140) among the heads of the families and of 41.42%(70/169) among the children.The only variables showing a significant association were affiliation,where the risk category was “being the son/daughter of”,and the symptoms were abdominal pain,sleeping disorder,and anal itch.Families with a member infected with parasite were considered Positive Families(PF)and they were 40/70(57.14%),only 5%(2/40)of the PF had 100% of their members infected with the parasite.The logistic regression models applied showed that the risk categories were mainly affiliation(son/daughter) and housing(satisfactory)among others. CONCLUSION:The presence of E.vermiculariswas proved in one third of the studied population.The frequency of families with all their members infected with the parasite was very low.Most of the studied personal,sociocultural, and environmental variables did not turn out to be significantly associated with the presence of the parasite.An association with the category of“son/daughter”and housing classified as“satisfactory”was determined.The latter may be due to the fact that the people living in that category of housing have hygienic practices at home that favour the distribution of the eggs in the environment.The presence of the analysed symptoms was associated with the presence of the parasite, thus strengthening the need of periodical control of the population showing at least one of these symptoms.

以人口高质量发展应对老龄化城乡倒置的挑战

纵观全球,老龄化城乡倒置现象具有普遍性和阶段性特征。对中国而言,随着由乡入城人口的地域流动,老龄化城乡倒置格局不断演变,呈现出“农村先老、农村快老、农村更老、农村高老、农村弱老”的特征,给中国式现代化发展带来诸多挑战。以人口高质量发展为核心积极应对老龄化城乡倒置问题,需从建设人才队伍、提升人口素质、优化人口布局、提高老年人生产生活质量等方面着手,以实施乡村振兴战略为契机,推进城乡全面深度融合发展,促进共同富裕。

中国式现代化背景下超老龄农村的乡村振兴

中国式现代化是人口规模巨大的现代化,也是全体人民共同富裕的现代化,适应人口变化趋势是中国式现代化与乡村振兴的应然选择和必然之路。当前人口老龄化程度持续加深,叠加长期存在的“城乡倒置”现象,使得农村地区已有近1/4的区域率先进入超老龄社会,其共同面临劳动力与人才老化、乡村发展能力弱化以及养老服务需求增加的现实挑战。为应对挑战,超老龄农村依靠尚存的人口机会窗口与内生的资源禀赋维系发展。在此基础上,乡村振兴战略通过外部资源输入的方式支持乡村发展,以解决农村发展不充分的矛盾、弥合区域发展不平衡的差距。然而,内生资源形塑的区域差异与乡村振兴推进过程中“整齐划一”的发展模式导致的匹配“错位”现象屡见不鲜。因此,为促进区域协同发展、实现超老龄农村的乡村振兴并最终达成共同富裕与中国式现代化,本研究从保障基本、深入发展和城乡融合三个阶段契合超老龄农村不同的发展基础,探索适合超老龄农村的乡村振兴道路。

乡村振兴助力农村养老:现实驱动、作用机理与实现路径

党的二十大提出要全面推进乡村振兴。助力农村养老既是乡村振兴的重要任务,也是农村养老的压力使然。当前,农村面临着人口快速老龄化、家庭养老功能弱化、留守与空巢老人现象严重、养老保障体系不完善等现实问题,在乡村振兴的过程中,需要大力推进农村养老保障体系建设。乡村振兴的举措、目标、原理与农村养老保障体系建设的举措、目标、原理具有内在一致性,推进乡村振兴的过程,也是加强农村养老保障体系建设的过程。应该大力推进乡村产业振兴,为农村养老奠定坚实的经济基础;推进乡村人才振兴,为农村养老提供人才支撑;推进乡村文化振兴,营造良好的农村养老氛围;推进乡村生态振兴,为农村老年人创造舒适的生活环境;推进乡村组织振兴,为农村养老提供坚强的组织保障。

差序整合:农村互助养老实现的机制分析

农村互助养老作为居家养老和机构养老的重要补充,是解决农村深度老龄化问题的有效路径。基于差序格局理论,在“关系—制度”分析框架和“差序整合”概念下,通过对河南省W县农村互助养老实践的考察发现,当地基层党组织成功借助乡土社会关系的差序规则,有序动员老人的亲友、邻里、同乡等为其提供养老服务。究其实现机制,具体包括以重塑认知为重点的制度嵌入、以均衡互利为核心的关系整合、以满足需求为关键的行动激励、以责任践履为要求的多方问责机制,差序整合为农村互助养老的可持续发展提供了规引制度、关系基础、参与动力和履责保障,实现了社会关系、制度规约、行动主体的全面整合,推动了农村养老服务高质量发展。
