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.

Secular Changes of Stature in Rural Children and Adolescents in China, 1985-2010

Objective To analyze and assess secular change in stature in rural children and adolescents in China from 1985 to 2010. Methods Data were obtained from the 6 rounds of the Chinese National Survey on Student＇s Constitution and Health. The subjects enrolled in the study were children and adolescents aged 7-18 years in rural areas of provincial capitals. Results An overall positive secular trend in stature occurred in rural areas of provincial capitals in China from 1985 to 2010. The overall average increase rates were 3.1 and 2.4 cm/decade for boys and girls, respectively. The total body height increases for grown up boys and girls were 3.6 and 2.3 cm and the increase rates were 1.4 and 0.9 cm/decade, respectively. There were differences in body height increase among eastern, central and western regions. The average body height of the children or adolescents in eastern region was highest, followed by central region and western region. The overall increase rates in central region were highest among the three regions. The difference between eastern/central region and western region was obvious. 〈br〉 Conclusion Positive secular trend in stature of children or adolescents has occurred in rural area of China, and rural boys and girls showed a great potential for continuous growth. More attention should be paid to the differences in children＇s body height between western region and eastern/central region.

Health-related quality of life among rural residents aged 45-69 years in Hua County, Henan Province, China： Results of ESECC Trial for esophageal cancer screening with endoscopy

Objective： There have been few population-based studies evaluating health related quality of life（HRQOL） in rural populations in China, and this study aimed to assess the current status of and risk factors for HRQOL in a general rural population in high risk region of esophageal cancer in China.Methods： From November 2015 to September 2016, 12,085 permanent residents aged 45–69 years from 257 villages in the Endoscopic Screening for Esophageal Cancer in China（ESECC） trial（Clinical Trials.gov：NCT01688908） randomly selected from Hua County, Henan Province, China were interviewed. The EQ-5 D-3 L,a generic measure of HRQOL, and a questionnaire were used to assess their HRQOL and potential risk factors.Results： Among all the participants, 30.62% of the participants reported problems in at least one EQ-5 D dimension. Pain/discomfort（25.52%） was the most frequently reported problem followed by anxiety/depression（7.97%）, mobility（5.82%）, usual activities（2.61%） and self-care（1%）. These rural residents had a mean EQ-5 D index score of 0.948, and lower EQ-5 D index scores were associated with older age, female gender, lower levels of household annual per capita income, living alone, using shallow wells as main source of drinking water, exposure to family members smoking, testiness, unhealthy dietary habits, overweight or obesity, upper gastrointestinal cancer related symptoms and chronic diseases.Conclusions： Rural residents in China have a relatively low quality of life. Health promotion programs in this population should focus on the elderly, especially elderly women and the elderly living alone. Improving basic living circumstances and primary medical care services should be priorities. Results of this study will also serve as the basis for the cost-utility evaluation in our ESECC screening trial.

Health Disparities among the Western, Central and Eastern Rural Regions of China after a Decade of Health Promotion and Disease Prevention Programming

Summary： Health disparities between the western, central and eastern regions of rural China, and the impact of national health improvement policies and programming were assessed. A total of 400 counties were randomly sampled. ANOVA and Logistic regression modeling were employed to estimate differ- ences in health outcomes and determinants. Significant differences were found between the western, central and eastern rural regions in community infrastructure and health outcomes. From 2000 to 2010, health indicators in rural China were improved significantly, and the infant mortality rate （IMR）, mater- nal mortality rate （MMR） and under 5 mortality rate （U5MR） had fallen by 62.79%, 71.74% and 61.92%, respectively. Central rural China had the greatest decrease in IMR （65.05%）; whereas, western rural China had the greatest reduction in MMR （72.99%） but smallest reduction in U5MR （57.36%）. Despite these improvements, Logistic regression analysis showed regional differences in key health outcome indicators （odds ratios）： IMR （central： 2.13; western： 5.31）, U5MR （central： 2.25; western： 5.69）, MMR （central： 1.94; western： 3.31）, and prevalence of infectious diseases （central： 1.62; western： 3.58）. The community infrastructure and health outcomes of the western and central rural regions of China have been improved markedly during the first decade of the 21st century. However, health dis- parities still exist across the three regions. National efforts to increase per capita income, community empowerment and mobilization, community infrastructure, capacity of rural health facilities, and health literacy would be effective policy options to attain health equity.

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.

Knowledge of COVID-19 and its prevention among rural residents in Fuqing,China

Objectives:Rural areas are the weakest place for epidemic prevention and control,yet few studies have specifically conducted surveys in rural areas.The purpose of this study is to assess rural residents’knowledge of the COVID-19 and its prevention in China.Methods:A cross-sectional survey study containing 1,426 samples was conducted in Fuqing,China to assess rural residents’knowledge of the COVID-19 and its prevention.Logistic regression was used to identify potential differences in participants’knowledge of COVID-19 and its prevention and control in different population subgroups.Results:The mean and median of residents’knowledge of COVID-19 was 5.53 and 6 points,respectively.The mean and median of residents’knowledge related to self-protection against COVID-19 was 10.34 and 11 points,respectively.Older adults(AOR45e59=2.26,95%CI 1.20 to 4.27;AOR60-69=3.13,95%CI 1.63 to 5.98;AOR70=4.68,95%CI 2.35 to 9.33)were more deficient in knowledge of COVID-19.Those who were better educated and with a higher average annual household income were less likely to be deficient in the knowledge of COVID-19 and knowledge of self-protection against COVID-19.Moreover,those who were single,divorced,or widowed(AOR=1.67,95%CI 1.13 to 2.46)were more deficient in the knowledge of self-protection against COVID-19.Conclusions:Our study suggests that when facing a pandemic like COVID-19,the key is to inform the public to understand simple and effective self-protection measures.Therefore,we call on the govern-ments to give priority to publicity and education on self-prevention measures for the targeted pop-ulations and regions.This is most evident among the vulnerable groups like those who were unmarried,elderly,and those with low education or low income.Similar suggestions may be of use in other countries as well.

Antibiotic prescribing patterns for upper respiratory tract infections in rural Western China

Objective To explore the prescribing patterns of outpatients receiving antibiotics for upper respiratory tract infections(URTIs)in rural Western China and to identify the correlation in terms of doctors and patients characteristics.Methods Totally 7 678 prescriptions for URTIs were collected from 680 primary health village clinics of 40 counties across 10 provinces of Western China.Two outcome variables were used in the analysis:the occurrence of prescribing at least one antibiotic drug for an URTI and the occurrence of prescribing two or more antibiotics for an URTI.GEE logistic regression models were used to examine the socioeconomic and demographic determinants of the above two outcome variables.Results The percentage of prescribing at least one antibiotic for URTIs was 48.6% while the percentage of prescribing antibiotic combination(two or more antibiotics)was 4.6%.The two measurements of antibiotic utilization differed remarkably among the 10 provinces.Patients diagnosed with tonsillitis and faucitis had higher odds(OR=8.86 for tonsillitis and OR=4.64 for faucitis)of antibiotic prescription than patients with other diagnosis of URTIs.Patients with tonsillitis and faucitis also had higher odds(OR=3.82 for tonsillitis and OR=2.71 for faucitis)of multiple antibiotic prescription than those with other diagnosis of URTIs.The number of drugs per prescription and injection in prescriptions were also significant predictors of antibiotic and multiple antibiotic utilization for URTIs.Conclusion It is concluded that the percentage of antibiotic prescription for URTIs is higher in rural Western China than in most of other countries with available data and that prescriptions of antibiotics for URTIs are associated with residence regions of patients,URTI diagnosis and background information on drug prescription.

Reasons for and Countermeasures against Gradient Transfer of Rural Population——A Case Study of Chongqing

We take Chongqing as an example to analyze reasons for rural population gradient transfer from such factors as social system,industrial development,urban planning,and living costs.Finally,we present four policies and suggestions,including promoting urban construction,increasing investment in rural areas,pushing forward construction of labor market,and bringing safeguarding function into full play.

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.

Review of Poverty Alleviation Work in Rural Areas in China and Its Future Prospects

Since the launched of reform and opening up,the Chinese government has made great efforts and provided a lot of funds to promote poverty alleviation and development in rural areas China has made great achievements in the cause of poverty alleviation and these have been recognized by the international community The infrastructure in poverty-stricken areas has also been continuously improved,and industrial activities have been encouraged in poverty-stricken areas to help promote self-reliance As a result of the government's actions the poor rural population has been greatly reduced,and rural people's living standards have been greatly improved Since the 18^(th) National Congress of the Communist Party of China,the central government has put forward a strategy of accurate poverty alleviation,implemented poverty alleviation projects in areas where poverty has stubbornly persisted and enhanced its efforts to finally eliminate poverty Under the vigorous leadership of the CPC,China is expected to achieve the goal of eliminating absolute poverty nationwide ahead of schedule

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.

The process and approach for the“citizenization”of Chinese rural migrant populations

China has a large rural migrant population,the country’s urbanization rate is low,and the cost of urbanization is high.These factors make the promotion of urbanization in China a long,arduous,and expensive task.By identifying and defining key elements of China’s urbanization transformation,this paper calculates the degree of China’s current transformation and proposes an approach based on systemic data to facilitate the continued process of transforming rural populations into citizens with full urban residential rights,herein referred to as“citizenization.”This paper finds that only about 40%of rural migrants had transformed into urban residents in 2011,and this share remained stagnant in 2012.Meanwhile,according to the sixth demographic census,the incomplete urbanization rate-calculated based on the difference between the share of the registered non-agriculture population as a percentage of the total population and the share of permanent urban residents-reached 23 percentage points.This thesis argues that it is necessary to advance the transformation process in a steady,stage-by-stage manner,including by carrying out multi-pronged efforts in various fields at various levels,and establishing a diversified cost-sharing mechanism,so as to achieve higher-quality,rational urbanization in China.

Analysis of Methodology for the Application of Stratified Random Sampling with Optimum Allocation： The Case Study of Forest Bioenergy

In this paper, analysis of methodology was realized for the application of stratified random sampling with optimum allocation in the case of a subject of research which concerns the rural population and presents high differentiations among the three strata in which this population could be classified. The rural population of Evros Prefecture （Greece） with criterion the mean altitude of settlements was classified in three strata, the mountainous, semi-mountainous and fiat population for the estimation of mean consumption of forest fuelwood for covering of heating and cooking needs in households of these three strata. The analysis of this methodology includes： （1） the determination of total size of sample for entire the rural population and its allocation to the various strata; （2） the investigation of effectiveness of stratification with the technique of analysis of variance （One-Way ANOVA）; （3） the conduct of sampling research with the realization of face-to-face interviews in selected households and （4） the control of forms of the questionnaire and the analysis of data by using the statistical package for social sciences, SPSS for Windows. All data for the analysis of this methodology and its practical application were taken by the pilot sampling which was realized in each stratum. Relative paper was not found by the review of literature.

Influence of the variation in rural population on farmland preservation in the rapid urbanization area of China

In the past 40 years,cultivated land has faced the continued anthropogenic interference,which has become a significant issue for cultivated land preservation during rapid urbanization.The purpose of this research was to reveal the spatio-temporal evolutionary characteristics of cultivated land and the correlation between rural population variation and farmland change in China.Fifty county-level administrative units in Zhejiang Province were selected as the study area wherein spatio-temporal evolution comparative analysis for every 5 years from 2000 to 2015 was conducted.This study used the pool method to estimate the impacts of the rural population variation,average slope,average elevation,rural residential disposable income,primary industry proportion,and road density on farmland utilization efficiency from the spatial perspective,which is represented by landscape metrics including the mean patch size,edge density,area weighted mean shape index,and area weighted mean patch fractal dimension.This study showed that the cultivated land landscape index continued to rise after 2000 and then started decreasing after 2010,indicating a reduction in human interference after 2010.The spatial variation of rural population of all county-level administrative units decreased from 2000 to 2010,and 62%of them began to increase after 2010.The regression analysis results showed that the spatial variation of rural population was significantly and negatively correlated with the cultivated land landscape while the rural residential disposable income,average slope and primary industry proportion were all significantly and positively related to the cultivated land landscape index.The results implied that the loss of the agricultural labor force and the difficulty of sloping farmlands adapting to mechanized farming were unconducive to farmland utilization efficiency improvement,and the increase in nonagricultural activities in rural areas would increase the difficulty of cultivated land preservation.Our analysis suggests that local governments should improve the production efficiency of fragmented land or strengthen the construction control of housing and facilities in rural areas according to their regional urbanization development situation.

Education Universalization,Rural School Participation,and Population Density

In many developing countries,low population density may be a major reason for low school participation in rural areas,and the problem is likely to worsen with rapid urbanization.However,few studies have investigated empirically the role of population density in rural education,especially the moderating effect of population density on the outcomes of education policies.This study aims to fill this gap in the literature.From 1999 through the early 2000s,China launched a set of major nationwide policies aimed at universalizing 9-year compulsory education in rural areas.Using difference-in-differences and triple difference strategies,we show that the policies significantly increased the probability of junior high school enrollment of rural children and,more importantly,these policies were more effective in densely populated regions.These findings confirm the imporance of population density to rural education.

Public Health Insurance and Farm Labor Supply:Evidence from China's Rural Health Insurance Reform

This study examines the impact of China’s public health insurance program on the farm employment decisions of the rural population.Using a difference-in-differences(DID)model,this study indicates that the public health insurance reform led to reallocation of the rural labor force out of the farm sector by reducing the farm employment and increasing the likelihood of rural residents working in both the farm and nonfarm sectors.This research finds that rural female residents who are of a younger age and in better health were more likely to leave farm employment when covered by public health insurance.Suggestive evidence also finds that such public health insurance reform increased the individual income of the farm population.

National trend of gastric cancer mortality in China(2003-2015):a population-based study

Background:Gastric cancer mortality decreased substantially over the last decades in most countries worldwide.This study aimed to assess the most recent national trend of gastric cancer mortality and examine the disparity of gastric cancer mortality between rural and urban areas in China.Methods:The crude mortality data of gastric cancer by sex,age group,and area were obtained from China Health Statistical Yearbooks(2003-2015)covering 10%of Chinese population.The age-standardized rates of mortality(ASRM)of gastric cancer in rural and urban areas were estimated using the 2010 Chinese Census population stratified by age,sex,and area.The trend of mortality of gastric cancer was assessed by using Joinpoint analysis.Results:During the 13-year period,the ASRM was reduced from 31.5/100,000 in 2003 to 20.9/100,000 in 2015 in rural areas and from 18.9/100,000 in 2003 to 14.5/100,000 in 2015 in urban areas.In the male population,the annual percent changes of mortality were−2.2%in urban areas(95%confidence interval[CI]−3.8%to−0.6%;P<0.001)and−3.4%in rural areas(95%CI−5.1%to−1.8%;P<0.001).In the female population,the annual percent changes of mortality were−2.7%in urban areas(95%CI−4.2%to−1.2%;P<0.001)and−4.6%in rural areas(95%CI−5.5%to−3.7%;P<0.001).Conclusions:The declining trend of mortality of gastric cancer was presented from 2003 to 2015 in both rural and urban areas in China.The decrease in gastric cancer mortality is greater in rural areas than in urban areas in China.

Agriculture Modernization

Rural work conference maps out reform plans toimprove China＇s agriculture industryChina hopes to reform its agriculture sector this year to increase food produce quality,reduce the grain oversupply and help rural populations living in poverty achieve prosperity.The plan was laid out at the end of December of last year when Chinese leaders held a central rural work conference to review how the agriculture industry performed in 2015
