In Mali, few studies have been conducted on the prevalence of cardiovascular risk factors and diseases according to place of residence. The aim of this study was to assess the prevalence of risk factors and cardiovascular diseases according to residents in town of Bougouni and its rural area (southern Mali). Methods: This was a retrospective descriptive study from February 2019 to March 2024. All patients who visited the “CENTRE MEDICAL DE BOUGOUNI” clinic with known or suspected heart disease during the study period were included. Data were collected from medical records. Incomplete or unusable records were excluded. Data were processed using SPS version 22 software. Results: we included 452 patients with an average age of 50 ± 19 years. High blood pression has been found in 42.70% of cases, with higher prevalence in urban areas (47.01%) than in rural areas (41.50%). Diabetes and smoking were found respectively 5.31% and 8.19% in our population. The prevalence of diabetes was higher in urban areas (5.97%) than rural area (5.35%). smoking prevalence was higher in rural areas (8.49%) than urban areas (6.72%). Alcoholism was found in 2.21% of cases with a little difference between rural area (2.24%) and urban area (2.20%). 31.63% of our patients had no cardiovascular factor. Dyspnea was the reason of consultation in 5.75% of cases and atypical precordialgia in 13.72%. Headaches and dizziness in 8.63% of cases and 21.90% of patients presented other non-specific symptoms. Diagnosis of idiopathic dilated cardiomyopathy was found in 23.45% of cases with higher prevalence in rural areas (28.30%) than urban areas (13.43%). Ischaemic heart disease accounted for 9.29% of cases with a higher prevalence in rural areas (10.38%) than in urban areas (6.71%). PPCMs accounted for 5.98% of cases, with a slight increase in urban areas (6.66%) compared with rural areas (5.68%). Rheumatic valvulopathy accounted for 2.21% of cases;2.84% in rural areas and 0.74% in urban areas. Other valvular diseases accounted for 3.76% of cases;4.73% in rural areas and 1.48% in urban areas. Right heart diseases accounted for 3.98% of cases and stroke for 1.77%. Conclusion: The prevalence of cardiovascular risk factors and heart diseases is high in the rural and urban population of the town of Bougouni and its surroundings (Mali). Excepted smoking, the prevalence of other CV risk factors is higher in urban areas, whereas the prevalence of idiopathic dilated cardiomyopathy and ischemic heart disease is higher in rural areas. These data could serve as a basis for developing tailored preventive strategies, depending on the place of residence. 展开更多

Introduction: Unmet need for family planning (UNFP) is defined as women with unmet needs who want to stop or delay childbearing but are not using any method of contraception. The objective of this study was to analyze the factors associated with unmet needs for family planning among couples living in rural and urban areas of Guinea in 2019. Methodology: This was a prospective, analytical cross-sectional, multicenter study of a six-month period from August 1, 2018 to January 31, 2019, focusing on couples with unmet needs for family planning. Result: Among 189 couples interviewed, 567 had UNFP (33.3%), the reasons for not using modern contraceptive methods were desire for pregnancy (AOR = 2.74, 95% CI: 1.74, 4.31), husband’s refusal (AOR = 0.23, 95% CI: 0.06, 0.81), spousal attitude (AOR = 0.20, 95% CI: 0.130, 30), birth spacing (AOR = 2.10% to 95%: 1.16, 3.82), difficulty with a new pregnancy (AOR = 0.17, 95% CI: 0.04, 0.74), and spousal attitude (AOR = 0.20, 95% CI: 0.14, 0.30). Conclusion: The involvement of spouses, especially in rural communities, would help achieve family planning objectives and reduce unmet needs for family planning. 展开更多

This paper examines national urban agglomerations by taking factor flows as the focal point as the research subject.By dividing the stages of urban agglomeration development,a comprehensive framework of urban shrinkage is constructed,encompassing economic,population,and social shrinkage.The study explores the spatial distribution characteristics of urban shrinkage during different stages of urban agglomeration and investigates the influencing factors using a geographic detector model.The findings reveal that urban shrinkage within urban agglomerations is widely spread,predominantly in peripheral areas.During the diffusion stage,urban shrinkage is scattered,with population shrinkage concentrated in peripheral regions,economic shrinkage concentrated on old industrial cities,and social shrinkage concentrated on the northeast.The outcomes of the geographic detector model indicate that traffic flow,capital flow,information flow,node importance,network connectivity,government investment,openness,and environmental regulations all play significant roles in shaping the spatial distribution of urban shrinkage. 展开更多

Urbanization is one of the driving forces for the land use change in type and structure, and its prominent effect is to convert rural land to urban land. This paper takes Shan-dong Province as an example to analyze the current situation of the mutual conversion between the urban and rural areas from the aspects of the structure of land use, the decreasing tendency of the cultivated land, the changes of land use in urban and rural residential areas. It points out that cultivated land is converted to residential area land, industrial and/or mining area land. The relationship between the urban area land and the cultivated land is more direct; meanwhile, the changes of rural residential area lag behind obviously. The decrease of the cultivated land and the decline of soil quality will be the two difficult problems in the process of urbanization. 展开更多

Background: Traditional cardiovascular risk factors (CVrf) like hypertension, diabetes, dyslipidemia, obesity, smoking have been studied extensively through theses in hospital studies. Therefore, recent published data from community based studies are rare in Mali. Available data are old justifying to perform a community based study on traditional CVrf in rural and urban areas. Materials and Methods: We retrospectively performed a study which data stemmed from the last STEPS survey carried out in 2013 in some rural and urban areas of Mali. We studied hypertension, diabetes, tobacco smoking, obesity based on body mass index, waist circumference and waist-to-hip ratio. After bivariates analyses, we conducted a logistic regression with rural/urban as dependent variable using SPSS as analysis software for this purpose. Results: Weight, height, WC and HC were higher in urban area with 69.77 Kg, 169.13 cm, 85.98 cm and 97.26 cm compared to 66.27, 165.42, 81.46 and 93.23 in rural area (p as more prevalent in urban area while elevated waist-to-hip ratio was more prevalent in rural area. But in logistic regression for female, the Odds for Tobacco smoking rural as reference was 0.334 [CI: 0.151 - 0.738] (p = 0.007) and that for WHr is 0.582 [CI: 0.415 - 0.815] (p p p = 0.038). Conclusion: Traditional cardiovascular risk factors have high prevalence in this study and need to be monitored with larger studies. Female predictors were raised waist circumference in favour of urban and tobacco smoking and waist-to-hip ratio in favour of urban dwellers. Male diabetes was the only predictor we found. 展开更多

On the basis of survey,drawing on economic growth theory,we analyze the main form of exogenous growth and regional applicability in Hebei Province,and point out that some exogenous driving forces are effective ways to accelerate rural construction,such as " the promotion of agriculture by industry" and " developing the rural areas with the aid of the urban areas". However,human capital,technology,incentive institutional arrangement,agricultural industry clusters and other endogenous growth factors are fundamental to sustainable development of rural construction,so it is necessary to make them play a fundamental role in increasing farmers' income and promoting agricultural development. 展开更多

Radon levels were measured in 59 water samples of rural and urban places of Bangalore city following procedures of standardized techniques. Though water level of radon above 100 Bqll-1 of WHO is ascribed to causes of lung cancer and leukaemia, very low levels were found in different urban and rural places, but urban-rural gradient observed significantly higher urban levels than rural levels. Correlation between depth of water sampled and radon levels estimated indicates that in urban places, lower water depth is related to higher radon levels, while it is vice versa in rural. It is due to more water use for rural agriculture and more urban water pollution and granite quarries. In comparison to other countries, it is observed that water radon levels are at wide ranges from the lowest to the highest estimated with different techniques and differ due to types of water, soil, rocks and sampling season. 展开更多
