Informing the surgical workforce pathway: how rural community characteristics matter.

INTRODUCTION: Rural areas worldwide face a general surgeon shortage, limiting rural populations' access to surgical care. While individual and practice-related factors have been well-studied in the US, we need a better understanding of the role of community characteristics in surgeons' location choices. This study aimed to understand the deeper meanings surgeons associated with community characteristics in order to inform efforts spanning the rural surgeon workforce pathway, from early educational exposures, and undergraduate and graduate medical education, to recruitment and retention. METHODS: We conducted a qualitative, descriptive interview study with general surgeons in the Midwestern US about the role and meaning of community characteristics, exploring their backgrounds, education, practice location choices, and future plans. We focused on rural surgeons and used an urban comparison group. We used convenience and snowball sampling, then conducted interviews in-person and via phone, and digitally recorded and professionally transcribed them. We coded inductively and continued collecting data until reaching code saturation. We used thematic network analysis to organize codes and draw conclusions. RESULTS: A total of 37 general surgeons (22 rural and 15 urban) participated. Interviews totaled over 52 hours. Three global themes described how rural surgeons associated different, often deeper, meanings with certain community characteristics compared to their urban colleagues: physical environment symbolism, health resources' relationship to scope of practice, and implications of intense role overlap (professional and personal roles). All interviewees spoke to all three themes, but the meanings they found differed importantly between urban and rural surgeons. Physical landscapes and community infrastructure were representative of autonomy and freedom for rural surgeons. They also shared how facilities, equipment, staff, staff education, and surgical partners combined to create different scopes of practice than their urban counterparts experienced. Often, rural surgeons found these resources dictated when they needed to transfer patients to higher-acuity facilities. Rural surgeons experienced role overlap intensely, as they cared for patients who were also friends and neighbors. CONCLUSION: Rural surgeons associated different meanings with certain community characteristics than their urban counterparts. As they work with prospective rural surgeons, educators and rural communities should highlight how health resources can translate into desired scopes of practice. They also should share with trainees the realities of role overlap, both how intense and stressful it can be but also how gratifying. Educators should include the rural social context in medical and surgical education, looking for even more opportunities to collaborate with rural communities to provide learners with firsthand experiences of rural environments, resources, and role overlap.

Self-identified rurality in a nationally representative population in the US.

INTRODUCTION: In the US, health services research most often relies on Rural-Urban Commuting Area (RUCA) classification codes to measure rurality. This measure is known to misrepresent rurality and does not rely on individual experiences of rurality associated with healthcare inequities. We aimed to determine a patient-centered RUCA-based definition of rurality. METHODS: In this cross-sectional study, we conducted an online survey asking US residents, 'Do you live in a rural area?' and the rationale for their answer. We evaluated the concordance between their self-identified rurality and their ZIP code-derived RUCA designation of rurality by calculating Cohen's kappa (κ) statistic and percent agreement. RESULTS: Of the 774 participants, 456 (58.9%) and 318 (41.1%) individuals had conventional urban and rural RUCA classifications, respectively. There was only moderate agreement between perceived rurality and rural RUCA classification (κ=0.48; 95% confidence interval (CI)=0.42-0.54). Among people living within RUCA 2-3 defined urban areas (n=51), percent agreement was only 19.6%. Discordance was driven by their perception of the population density, proximity to the nearest neighbor, proximity to a metropolitan area, and the number of homes in their area. Based on our results, we reclassified RUCA 2-3 designations as rural, resulting in an increase in overall concordance (κ=0.56; 95%CI=0.50-0.62). DISCUSSION: Patient-centered rural-urban classification is required to effectively evaluate the impact of rurality on health disparities. This study presents a more patient-centric RUCA-based classification of rurality that can be easily operationalized in future research in situations in which self-reported rural status is missing or challenging to obtain. CONCLUSION: Reclassification of RUCA 2-3 as rural represents a more patient-centric definition of rurality.

Associations between digital literacy, health literacy, and digital health behaviors among rural residents: evidence from Zhejiang, China.

OBJECTIVE: Within the digital society, the limited proficiency in digital health behaviors among rural residents has emerged as a significant factor intensifying health disparities between urban and rural areas. Addressing this issue, enhancing the digital literacy and health literacy of rural residents stands out as a crucial strategy. This study aims to investigate the relationship between digital literacy, health literacy, and the digital health behaviors of rural residents. METHODS: Initially, we developed measurement instruments aimed at assessing the levels of digital literacy and health literacy among rural residents. Subsequently, leveraging micro survey data, we conducted assessments on the digital literacy and health literacy of 968 residents in five administrative villages in Zhejiang Province, China. Building upon this foundation, we employed Probit and Poisson models to empirically scrutinize the influence of digital literacy, health literacy, and their interaction on the manifestation of digital health behaviors within the rural population. This analysis was conducted from a dual perspective, evaluating the participation of digital health behaviors among rural residents and the diversity to which they participate in such behaviors. RESULTS: Digital literacy exhibited a notably positive influence on both the participation and diversity of digital health behaviors among rural residents. While health literacy did not emerge as a predictor for the occurrence of digital health behavior, it exerted a substantial positive impact on the diversity of digital health behaviors in the rural population. There were significant interaction effects between digital literacy and health literacy concerning the participation and diversity of digital health behaviors among rural residents. These findings remained robust even after implementing the instrumental variable method to address endogeneity issues. Furthermore, the outcomes of robust analysis and heterogeneity analysis further fortify the steadfastness of the aforementioned conclusions. CONCLUSION: The findings suggest that policymakers should implement targeted measures aimed at enhancing digital literacy and health literacy among rural residents. This approach is crucial for improving rural residents' access to digital health services, thereby mitigating urban-rural health inequality.

Trends in parkinson's disease mortality in China from 2004 to 2021: a joinpoint analysis.

BACKGROUND: This study aimed to analyze the trends of Parkinson's disease (PD) mortality rates among Chinese residents from 2004 to 2021, provide evidence for the formulation of PD prevention and control strategies to improve the quality of life among PD residents. METHODS: Demographic and sociological data such as gender, urban or rural residency and age were obtained from the National Cause of Death Surveillance Dataset from 2004 to 2021. We then analyzed the trends of PD mortality rates by Joinpoint regression. RESULTS: The PD mortality and standardized mortality rates in China showed an overall increasing trend during 2004-2021 (average annual percentage change [AAPC] = 7.14%, AAPCASMR=3.21%, P < 0.001). The mortality and standardized mortality rate in male (AAPC = 7.65%, AAPCASMR=3.18%, P < 0.001) were higher than that of female (AAPC = 7.03%, AAPCASMR=3.09%, P < 0.001). The PD standardized mortality rates of urban (AAPC = 5.13%, AAPCASMR=1.76%, P < 0.001) and rural (AAPC = 8.40%, AAPCASMR=4.29%, P < 0.001) residents both increased gradually. In the age analysis, the mortality rate increased with age. And the mortality rates of those aged > 85 years was the highest. Considering gender, female aged > 85 years had the fastest mortality trend (annual percentage change [APC] = 5.69%, P < 0.001). Considering urban/rural, rural aged 80-84 years had the fastest mortality trend (APC = 6.68%, P < 0.001). CONCLUSIONS: The mortality rate of PD among Chinese residents increased from 2004 to 2021. Male sex, urban residence and age > 85 years were risk factors for PD-related death and should be the primary focus for PD prevention.

Examining the impact of legalization on the prevalence of driving after using cannabis: A comparison of rural and non-rural parts of Canada.

OBJECTIVE: The purpose of this study was to examine the likelihood of driving after using cannabis, and of being a passenger with someone who is driving after using cannabis, in rural areas and non-rural areas before and after legalization. METHODS: A multi-wave analysis of Canada's National Cannabis Survey was conducted using logistic regression with interactions to predict the prevalence of driving after using cannabis, and of being a passenger with someone who is driving after using cannabis, in relation to place of residence (rural or non-rural) and in the weeks and months before and after legalization. Three time points were compared: pre-legalization, two months following legalization and 1 year after legalization. RESULTS: At the national level, there are no significant differences between the predicted estimates of driving after using cannabis for those who live in rural and non-rural areas. However, when examining the impact of legalization, we found a significant increase in driving after using cannabis among rural residents directly following legalization. Furthermore, it was observed that this increase in driving after using cannabis returns to pre-legalization rates one year after legalization. By contrast, in the weeks and months following legalization, driving after using cannabis decreased among those living in non-rural areas, and slowly increased soon thereafter. No significant differences were observed, in either time period or group, in the prevalence of being a passenger with someone who is driving after using cannabis. CONCLUSIONS: The finding of significantly higher risk of driving after use of cannabis soon after legalization in rural areas suggests a need for more attention to address immediate concerns for public safety. The increased potential for traffic injuries and deaths in other jurisdictions contemplating legalization supports the call for more and better targeted prevention efforts in rural communities that have far too often been overlooked and under-served.

[Prevalence and trends of low body weight among elderly population aged 60 years and above in China in 2002-2015].

OBJECTIVE: Understand the current situation and changing trends of low body weight in elderly population aged 60 years and above. METHODS: Data was collected from 2002 Chinese Nutrition and Health Survey, 2010-2013 Chinese Nutrition and Health Surveillance and 2015 Chinese Adult Chronic Disease and Nutrition Surveillance. Multi-stage stratified cluster random sampling was used for all surveys or surveillance. In 2002, 27 778 samples of people aged 60 and over were taken from 132 monitoring sites in mainland China. In 2010-2013, 34 581 subjects were selected from 150 monitoring points in mainland China. In 2015, 59 576 subjects were selected from 302 monitoring points in mainland China. Questionnaires collected basic information such as gender, and date of birth, and information such as height and weight were collected through physical examination. RESULTS: The prevalence of low body weight in the elderly aged 60 years and above showed a downward trend from 2002 to 2015 in China(P<0.01). The prevalence of low body weight decreased from 11.67% in 2002 to 5.19% in 2015. The prevalence of low body weight among males decreased from 11.51% in 2002 to 5.21% in 2015. The prevalence of low body weight among females decreased from 11.83% in 2002 to 5.17% in 2015. The prevalence of low body weight in the elderly aged 60 years and above showed an upward trend with age. The prevalence of low body weight in urban areas decreased from 5.85% in 2002 to 3.31% in 2015. The prevalence of low body weight in rural areas decreased from 16.25% in 2002 to 6.67% in 2015. The prevalence of low body weight in seven geographic regions of China decreased from 2002 to 2015. The prevalence of low body weight was highest in the elderly population aged 60 years and above in South China(9.49%(95%CI 8.61%-10.38%)) and lowest in North China(2.55%(95%CI 2.15%-2.95%)) in 2015. CONCLUSION: The prevalence of low body weight among the elderly aged 60 years and above in China decreased from 2002 to 2015. The prevalence of low body weight increased with age. The prevalence was higher in rural areas than in urban areas, and the prevalence in South China was higher than in other geographic regions.

Rural household vulnerability and COVID-19: Evidence from India.

The coronavirus disease 2019 (COVID-19) pandemic has affected vulnerable households' livelihoods in developing countries. Using high-frequency phone survey data from the World Bank, we assess rural Indian households' vulnerability and poverty status during the pandemic. Results reveal that over three-fifths of Indian rural households are vulnerable to poverty in the context of COVID-19, despite India's evident progress in mitigating poverty in the pre-pandemic era. Poverty plays a major role in accounting for variations in household vulnerability; however, the impact of risks on household welfare is not negligible. On average, households with more members, older household heads, and more outmigrants are more vulnerable to poverty during the pandemic. The impacts of the gender of the household head, access to masks, consumption loans, and COVID-related information are nevertheless insignificant. Results stress the urgent necessity of deploying concerted interventions to strengthen household vulnerability in rural India.

Association between environmental gradient of anthropization and phenotypic plasticity in two species of triatomines.

BACKGROUND: Triatoma garciabesi and T. guasayana are considered secondary vectors of Trypanosoma cruzi and frequently invade rural houses in central Argentina. Wing and head structures determine the ability of triatomines to disperse. Environmental changes exert selective pressures on populations of both species, promoting changes in these structures that could have consequences for flight dispersal. The aim of this study was to investigate the relationship between a gradient of anthropization and phenotypic plasticity in flight-related traits. METHODS: The research was carried out in Cruz del Eje and Ischilín departments (Córdoba, Argentina) and included 423 individuals of the two species of triatomines. To measure the degree of anthropization, a thematic map was constructed using supervised classification, from which seven landscapes were selected, and nine landscape metrics were extracted and used in a hierarchical analysis. To determine the flight capacity and the invasion of dwellings at different levels of anthropization for both species, entomological indices were calculated. Digital images of the body, head and wings were used to measure linear and geometric morphometric variables related to flight dispersion. One-way ANOVA and canonical variate analysis (CVA) were used to analyze differences in size and shape between levels of anthropization. Procrustes variance of shape was calculated to analyze differences in phenotypic variation in heads and wings. RESULTS: Hierarchical analysis was used to classify the landscapes into three levels of anthropization: high, intermediate and low. The dispersal index for both species yielded similar results across the anthropization gradient. However, in less anthropized landscapes, the density index was higher for T. garciabesi. Additionally, in highly anthropized landscapes, females and males of both species exhibited reduced numbers. Regarding phenotypic changes, the size of body, head and wings of T. garciabesi captured in the most anthropized landscapes was greater than for those captured in less anthropized landscapes. No differences in body size were observed in T. guasayana collected in the different landscapes. However, males from highly anthropized landscapes had smaller heads and wings than those captured in less anthropized landscapes. Both wing and head shapes varied between less and more anthropogenic environments in both species. CONCLUSIONS: Results of the study indicate that the flight-dispersal characteristics of T. garciabesi and T. guasayana changed in response to varying degrees of anthropization.

Sociodemographic and Behavioral Factors Associated With Hypertension and Depression in 4 Rural Communities in Northern Ghana: A Cross-Sectional Study.

OBJECTIVES: The prevalences of hypertension and depression in sub-Saharan Africa are substantial and rising, despite limited data on their sociodemographic and behavioral risk factors and their interactions. We undertook a cross-sectional study in 4 communities in the Upper East Region of Ghana to identify persons with hypertension and depression in the setting of a pilot intervention training local nurses and health volunteers to manage these conditions. METHODS: We quantified hypertension and depression prevalence across key sociodemographic factors (age, sex, occupation, education, religion, ethnicity, and community) and behavioral factors (tobacco use, alcohol use, and physical activity) and tested for association by multivariable logistic regression. RESULTS: Hypertension prevalence was higher in older persons (7.6% among 35- to 50-year-olds vs 16.4% among 51- to 70-year-olds) and among those reporting alcohol use (18.9% vs 8.5% between users and nonusers). In multivariable models, only older age (AOR 2.39 [1.02, 5.85]) and residence in the community of Wuru (AOR 7.60 [1.81, 32.96]) were independently associated with hypertension, and residence in Wuru (AOR 23.58 [7.75-78.25]) or Navio (AOR 7.41 [2.30-24.74]) was the only factor independently associated with depression. CONCLUSIONS: We report a high prevalence of both diseases overall and in select communities, a trend that requires further research to inform targeted chronic disease interventions.

Prevalence of cardiometabolic risk factors according to urbanization level, gender and age, in apparently healthy adults living in Gabon, Central Africa.

BACKGROUND: The prevalence of cardiometabolic risk factors (CMRFs) is increasing in sub-Saharan Africa and represents a serious public health issue. Accurate data are required to implement adapted prevention programs and healthcare strategies. Thus, the aim of this study was to estimate the prevalence rates of CMRFs according to the level of urbanization, age and gender in Gabon. METHODS: A cross-sectional study was conducted in northern (Bitam), western coast (Libreville, Melen) and southeast (Koulamoutou) areas of Gabon using the World Health Organization's (WHO) stepwise approach for the surveillance of chronic disease risk factors. Participants over 18 years of age, without known underlying disease, living in rural and urban areas of Gabon were included. Sociodemographic, biological, and behavioral data were collected. Univariate and multivariate analysis were used to identify the CMRFs. RESULTS: Of the 978 participants, 499 lived in urban and 479 in rural areas. Their median age was 38[28-50] years. Tobacco (26.1% vs 6.2%; p < 0.01) and excessive alcohol consumption (19.4% vs 9.6%; p < 0.01) predominated in rural than in urban areas, respectively. Urban dwellers had more often insufficient physical activity than rural people (29.5% vs 16.3%; p < 0.01). In total, 79.9% of participants aged under 54 years had a high blood pressure;10.6% of the younger participants had pre-hypertension. Metabolic syndrome was more frequent in women (21.7%) than in men (10.0%) (p < 0.01); 6.4% of men and 2.5% of women had a high Framingham score (p = 0.03). Finally, 54.0% of the participants had three or four CMRFs. The multivariate analysis showed that men were more likely to be smokers and to be at risk of pre-hypertension or high blood pressure (p < 0.01). Women were more likely to be obese or to have a metabolic syndrome (p < 0.01). Living in urban areas was also a risk factor for hypertension, diabetes, metabolic syndrome and high LDL cholesterol level. CONCLUSION: The prevalence of CMRFs was high in the study population. Disparities were observed according to urban and rural areas, gender and age. National prevention and healthcare strategies for cardiometabolic diseases in Gabon should consider these observed differences.

Infection Prevention and Control: Baseline Knowledge and Practices of TBAs in Rural Kano, Northwestern Nigeria.

BACKGROUND: Maternal infections remain a significant contributor to maternal mortality worldwide. Majority of births in northern Nigeria occur at home and are attended by Traditional Birth Attendants (TBAs). Little has been documented about their knowledge and practice on infection prevention and control practices in Kano, northern Nigeria. OBJECTIVES: This study evaluated the level as well as factors associated with TBAs' infection prevention and control knowledge and practices. METHODS: The study is the baseline phase of a quasi-experimental study, conducted in a rural LGA in Kano State, Nigeria. Using an adapted tool, 163 eligible TBAs were surveyed. Knowledge and practice of IPC were scored, aggregated, and dichotomized into good or poor. Binary logistic regression analysis was used to predict knowledge and practice of IPC. RESULTS: Majority (79.1%) of the TBAs exhibited poor IPC knowledge but many (78.5%) reported good practice. Good knowledge of IPC was predicted by the TBAs' age: a six-fold increased likelihood (AOR=6.25, 95% CI: 1.02- 38.53) and almost five-fold increased likelihood (AOR=4.75, 95% CI: 1.39- 16.24) for those in their second and fourth decades of life. TBAs who reported poor practice of IPC were 83% less likely (AOR=0.17, 95% CI: 0.03- 0.92) to have good knowledge of IPC. TBAs' practice was only linked to previous training (AOR=0.17, 95% CI: 0.04- 0.76). CONCLUSION: TBAs knowledge of IPC was low although reported practice was good. The need for tailored training interventions to enhance knowledge and skills for safe delivery care is paramount to improve maternal and neonatal outcomes.

CONTEXTE: Les infections maternelles restent une contribution significative à la mortalité maternelle dans le monde. La majorité des accouchements dans le nord du Nigeria ont lieu à domicile et sont assistés par des TBA. Peu de choses ont été documentées sur leurs connaissances et leurs pratiques en matière de prévention et de contrôle des infections à Kano, dans le nord du Nigeria. OBJECTIFS: Cette étude a évalué le niveau de connaissances et de pratiques des TBA en matière de prévention et de contrôle des infections, ainsi que les facteurs associés. MÉTHODES: L'étude est la phase de base d'une étude quasiexpérimentale, menée dans une LGA rurale de l'État de Kano, au Nigeria. En utilisant un outil adapté, 163 TBA éligibles ont été interrogés. Les connaissances et les pratiques en matière de PCI ont été évaluées, agrégées et dichotomisées en bonnes ou mauvaises. Une analyse de régression logistique binaire a été utilisée pour prédire les connaissances et les pratiques en matière de PCI. RÉSULTATS: La majorité (79,1 %) des TBA présentaient des connaissances médiocres en PCI, mais beaucoup (78,5 %) ont déclaré avoir de bonnes pratiques. De bonnes connaissances en PCI étaient prédites par l'âge des TBA : une probabilité multipliée par six (AOR=6,25, IC à 95 % : 1,02-38,53) et presque multipliée par cinq (AOR=4,75, IC à 95 % : 1,39-16,24) pour ceux dans leur deuxième et quatrième décennies de vie. Les TBA qui ont déclaré une mauvaise pratique de la PCI étaient 83 % moins susceptibles (AOR=0,17, IC à 95 % : 0,03-0,92) d'avoir de bonnes connaissances en PCI. La pratique des TBA était uniquement liée à une formation antérieure (AOR=0,17, IC à 95 % : 0,04­0,76). CONCLUSION: Les connaissances des TBA en matière de PCI étaient faibles bien que les pratiques déclarées étaient bonnes. La nécessité d'interventions de formation sur mesure pour améliorer les connaissances et les compétences en matière de soins de l'accouchement sécurisés est primordiale pour améliorer les résultats maternels et néonatals. MOTS-CLÉS: Accoucheuses Traditionnelles, Mortalité Maternelle, Infection Maternelle, Nigeria.

Current Status and Family Factors Influencing Caries in the Deciduous Teeth of Children 3-6 Years of Age in Families Residing in Rural Heishanzui Township.

PURPOSE: To determine the caries status in children's deciduous teeth and examine the influence of family oral health behaviours on the caries status. MATERIALS AND METHODS: This cross-sectional study included 329 children aged 3-6 years in rural Heishanzui Township, Hebei Province, China, and used a completely random sampling method. These children underwent physical and oral health examinations. The questionnaires were given to the parents and caregivers of the examined children. RESULTS: The prevalence of caries in the deciduous dentition among children aged 3-6 years was 80.55%, with a dmft index of 4.93. Children in the caries group ate sweets, chocolates, and carbonated drinks more frequently than did children in the caries-free group (p < 0.05). Children in the caries-free group brushed their teeth more frequently, with parents helping their children brush, more often than did those in the caries-affected group (p < 0.05). The level of parental education and annual household income also had statistically significant effects on the prevalence of caries in the two groups (p < 0.05). Logistic regression analysis revealed that the frequency of eating sweets was a risk factor for caries in deciduous teeth (odds ratio = 2.20; p < 0.05). CONCLUSION: The prevalence of caries in deciduous teeth among children aged 3-6 years in rural Heishanzui Township was high. Compared to children in the caries-affected group, the families and children in the caries-free group had better oral hygiene behaviours. Moreover, the frequency of eating sweets was shown to be a risk factor for caries in deciduous teeth in children aged 3-6 years.

Leveraging AI and Machine Learning to Develop and Evaluate a Contextualized User-Friendly Cough Audio Classifier for Detecting Respiratory Diseases: Protocol for a Diagnostic Study in Rural Tanzania.

BACKGROUND: Respiratory diseases, including active tuberculosis (TB), asthma, and chronic obstructive pulmonary disease (COPD), constitute substantial global health challenges, necessitating timely and accurate diagnosis for effective treatment and management. OBJECTIVE: This research seeks to develop and evaluate a noninvasive user-friendly artificial intelligence (AI)-powered cough audio classifier for detecting these respiratory conditions in rural Tanzania. METHODS: This is a nonexperimental cross-sectional research with the primary objective of collection and analysis of cough sounds from patients with active TB, asthma, and COPD in outpatient clinics to generate and evaluate a noninvasive cough audio classifier. Specialized cough sound recording devices, designed to be nonintrusive and user-friendly, will facilitate the collection of diverse cough sound samples from patients attending outpatient clinics in 20 health care facilities in the Shinyanga region. The collected cough sound data will undergo rigorous analysis, using advanced AI signal processing and machine learning techniques. By comparing acoustic features and patterns associated with TB, asthma, and COPD, a robust algorithm capable of automated disease discrimination will be generated facilitating the development of a smartphone-based cough sound classifier. The classifier will be evaluated against the calculated reference standards including clinical assessments, sputum smear, GeneXpert, chest x-ray, culture and sensitivity, spirometry and peak expiratory flow, and sensitivity and predictive values. RESULTS: This research represents a vital step toward enhancing the diagnostic capabilities available in outpatient clinics, with the potential to revolutionize the field of respiratory disease diagnosis. Findings from the 4 phases of the study will be presented as descriptions supported by relevant images, tables, and figures. The anticipated outcome of this research is the creation of a reliable, noninvasive diagnostic cough classifier that empowers health care professionals and patients themselves to identify and differentiate these respiratory diseases based on cough sound patterns. CONCLUSIONS: Cough sound classifiers use advanced technology for early detection and management of respiratory conditions, offering a less invasive and more efficient alternative to traditional diagnostics. This technology promises to ease public health burdens, improve patient outcomes, and enhance health care access in under-resourced areas, potentially transforming respiratory disease management globally.

[Association of triglyceride glucose index and risk of incident hypertension: a prospective cohort study].

Objective: To explore the relationship between the triglyceride glucose (TyG) index and the risk of developing hypertension among rural Chinese adults. Methods: A prospective cohort study was conducted from 2007 to 2008, involving 20 194 adults selected through random cluster sampling from a rural community in Luoyang City, Henan Province. Follow-ups were carried out in 2013-2014 and 2018-2020. After excluding participants with hypertension at baseline, those with missing TyG index data, individuals who passed away during follow-up, and those with incomplete hypertension status at the second visit, 9 802 participants were included in the analysis. Baseline and follow-up assessments included questionnaire interviews, physical measurements (including blood pressure), and blood sample collection for fasting lipid and glucose levels. Participants were divided into four groups according to TyG index quartiles, and a modified Poisson regression model was utilized to assess the association between TyG index quartiles and hypertension risk. Results: The study cohort comprised 9 802 participants with a median age of 48 (39, 57) years, including 3 803 males (38.80%). Participants were distributed across TyG index quartiles as follows: TyG<8.2 group (2 224 individuals), TyG 8.2-8.5 group (2 653 individuals), TyG 8.6-8.9 (2 441 individuals), and TyG≥9.0 (2 484 individuals). Over a follow-up period of (11.1±1.3) years, 3 378 subjects developed hypertension, resulting in a cumulative incidence of 34.46% (3 378/9 802). The risk of hypertension increased with higher TyG index quartiles (Ptrend<0.05). Compared to the TyG<8.2, the TyG 8.2-8.5 (RR=1.11, 95%CI 1.01-1.22, P=0.023), TyG 8.6-8.9 (RR=1.16, 95%CI 1.06-1.27, P=0.023), and TyG≥9.0 (RR=1.20, 95%CI 1.10-1.31, P=0.023) exhibited increased hypertension risk after adjusting for age, gender, educational level, and other potential confounders. Subgroup analyses based on gender and age at baseline yielded results consistent with the main analysis. Conclusions: The TyG index is positively correlated with the risk of developing hypertension in the rural adult population.

[Cancer survival analysis in Tianjin, 2010 to 2016].

Objective: Survival analysis of cancers' incidence data in Tianjin from 2010 to 2016 was conducted to provide the basis for formulating and evaluating regional health policies on cancer prevention and treatment. Methods: Registration data in Tianjin were used between January 1, 2010 to December 31, 2016 and patients were followed-up till 31 December, 2021. Life-table method was used to calculate the observed survival rate and Edered Ⅱ was used to calculate the relative survival rate. The data were stratified by year, gender, age group and cancer sites. Difference in survival curves between group was analyzed by Kaplan-Meier method and Log rank test. Joinpoint regression model was used to analyze the trend change. Results: The 5-year relative survival rates of cancer were 41.92% to 53.65% from 2010 to 2016 for residents in Tianjin, with an increasing trend (t=4.81, P=0.005), and the average was 48.56%. The survival rate of females was higher than that of males (57.71%vs. 39.20%), and the survival rate of urban residents was higher than that of rural residents (49.38% vs. 47.24%). The 5-year relative survival rates were 63.14%, 78.39%, 58.25% and 32.67% in 0-14, 15-44, 45-64 and 65 and above age groups, respectively. The median relative survival times of all cancer were 2.34 to 6.00 years from 2010 to 2016 in Tianjin, with an increasing trend (t=3.86, P=0.012). The average of median relative survival times was 4.11 years. The median survival time of females was longer than that of males (11.99 years vs. 2.03 years), and the time of urban residents were longer than that of rural residents (4.60 years vs. 3.43 years). The median relative survival time were 12.07, 11.92 and 1.34 years in 15-44, 45-64 and 65 and above age groups, respectively. Conclusions: The cumulative survival rate of cancer increased significantly from 2010 to 2016 in Tianjin, indicating that the prevention and treatment effect of cancer is obvious. The focus should be on male, rural areas, higher age group, and targeted prevention and treatment measures should be taken to lung, esophagus, liver, gallbladder and pancreatic cancer.

Why is there a gap in self-rated health among people with hypertension in Zambia? A decomposition of determinants and rural‒urban differences.

BACKGROUND: Hypertension affects over one billion people globally and is one of the leading causes of premature death. Low- and middle-income countries, especially the sub-Saharan Africa region, bear a disproportionately higher share of hypertension globally. Recent evidence shows a steady shift in the burden of hypertension from more affluent and urban populations towards poorer and rural communities. Our study examined inequalities in self-rated health (SRH) among people with hypertension and whether there is a rural‒urban gap in the health of these patients. We then quantified factors driving the health gap. We also examined how much HIV accounts for differences in self-rated health among hypertension patients due to the relationship between HIV, hypertension and health in sub-Saharan Africa. METHODS: We utilized the Zambia Household Health Expenditure and Utilization Survey for data on SRH and other demographic and socioeconomic controls. District HIV prevalence information was from the Zambia Population-Based HIV Impact Assessment (ZAMPHIA) survey. We applied the Linear Probability Model to assess the association between self-rated health and independent variables as a preliminary step. We then used the Blinder-Oaxaca decomposition to identify self-rated health inequality between urban and rural patients and determine determinants of the health gap between the two groups. RESULTS: Advanced age, lower education and low district HIV prevalence were significantly associated with poor health rating among hypertension patients. The decomposition analysis indicated that 45.5% of urban patients and 36.9% of rural patients reported good self-rated health, representing a statistically significant health gap of 8.6%. Most of the identified health gap can be attributed to endowment effects, with education (73.6%), district HIV prevalence (30.8%) and household expenditure (4.8%) being the most important determinants that explain the health gap. CONCLUSIONS: Urban hypertension patients have better SRH than rural patients in Zambia. Education, district HIV prevalence and household expenditure were the most important determinants of the health gap between rural and urban hypertension patients. Policies aimed at promoting educational interventions, improving access to financial resources and strengthening hypertension health services, especially in rural areas, can significantly improve the health of rural patients, and potentially reduce health inequalities between the two regions.

Study of association of leptin with leukocyte telomere length in a Chinese rural population.

BACKGROUND: Previous studies have demonstrated the relationship between adipocyte factors, insulin resistance, and other indicators with telomere length. However, these studies did not consider the influence of changes in different indicators on telomere length over time. Therefore, the aim of this study is to elucidate the impact of changes in adipocyte factors, HOMA-IR, and other indicators on the dynamic variation of telomere length. METHODS: The data were from a cohort study conducted in Ningxia, China. A total of 1624 subjects were analyzed. Adipokines and relative leukocyte telomere length (RLTL) were measured, and changes in Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), Homeostatic Model Assessment for ß-Cell Function (HOMA-ß), and Quantitative Insulin Sensitivity Check Index (QUICKI) were calculated. Generalized linear models evaluated associations between changes in adipokines and RLTL changes. Furthermore, univariate analyses examined the effects of changes in adipokines and insulin resistance indicators on ΔRLTL. RESULTS: The research findings indicate that females generally have shorter telomeres compared to males. In comparison to the low-level group of Δleptin (LEP), the high-level group of ΔLEP shows a negative correlation with ΔRLTL (B=-1.32, 95% CI (-2.38, -0.27)). Even after multivariable adjustments, this relationship persists (B=-1.31, 95% CI (-2.24, -0.23)). Further analysis reveals that after adjusting for ΔHOMA-IR, ΔHOMA-ß, and ΔQUICKI, the high-level group of ΔLEP still exhibits a significant negative correlation with ΔRLTL (B=-1.37, 95% CI (-2.43, -0.31)). However, the interaction effects between ΔHOMA-IR, ΔHOMA-ß, ΔQUICKI, and ΔLEP do not affect ΔRLTL. CONCLUSIONS: Elevated levels of leptin were significantly correlated with shortened telomere length. This suggests that increased leptin levels may impact overall individual health by affecting telomere length, underscoring the importance of measures to reduce leptin levels to mitigate the onset and progression of related diseases.

The influence of rurality on melanoma diagnosis in Indiana: A retrospective cohort study.

BACKGROUND: Research from across the United States has shown that rurality is associated with worse melanoma outcomes. In Indiana, nearly a quarter of all residents live in rural counties and an estimated 2180 cases of melanoma will be diagnosed in 2023. AIMS: This study examines how geographical location affects the stage of melanoma diagnosis in Indiana, aiming to identify and address rural health disparities to ultimately ensure equitable care. METHODS AND RESULTS: Demographics and disease characteristics of patients diagnosed with melanoma at Indiana University Health from January 2017 to September 2022 were compared using Students t-tests, Wilcoxon tests, chi-squared or Fisher's exact tests. Patients from rural areas presented with more pathological stage T3 melanomas (15.0% vs. 3.5%, p < 0.001) in contrast to their urban counterparts. Additionally, rural patients presented with fewer clinical stage I melanomas (80.8% vs. 89.3%) and more clinical stage II melanomas (19.2% vs. 8.1%), compared to urban patients, with no stage III (p = 0.028). Concerningly, a significantly higher percentage of the rural group (40.7%) had a personal history of BCC compared to the urban group (22.6%) (p = 0.005) and fewer rural patients (78.0%) compared to urban patients (89.4%) received surgical treatment (p = 0.016). CONCLUSION: Patients from rural counties in Indiana have higher pathological and clinical stage melanoma at diagnosis compared to patients from urban counties. Additionally fewer rural patients receive surgical treatment and may be at higher risk of developing subsequent melanomas.

Rural and urban differences in the prevalence and determinants of Type-2 diabetes in Bangladesh.

OBJECTIVE: To estimate the prevalence of Type 2 Diabetes (T2D) in urban and rural settings and identify the specific risk factors for each location. METHOD: We conducted this study using data from the 2017-18 Bangladesh Demographic and Health Survey (BDHS), sourced from the DHS website. The survey employed a stratified two-stage sampling method, which included 7,658 women and 7,048 men aged 18 and older who had their blood glucose levels measured. We utilized chi-square tests and ordinal logistic regression to analyze the association between various selected variables in both urban and rural settings and their relationship with diabetes and prediabetes. RESULTS: The prevalence of T2D was 10.8% in urban areas and 7.4% in rural areas, while pre-diabetes affected 31.4% and 27% of the populations in these respective settings. The study found significant factors influencing diabetes in both urban and rural regions, particularly in the 55-64 age group (Urban: AOR = 1.88, 95% CI [1.46, 2.42]; Rural: AOR = 1.87, 95% CI [1.54, 2.27]). Highly educated individuals had lower odds of T2D, while wealthier and overweight participants had higher odds in both areas. In rural regions, T2D risk was higher among caffeinated drink consumers and those not engaged in occupation-related physical activity, while these factors did not show significant influence in urban areas. Furthermore, urban participants displayed a significant association between T2D and hypertension. CONCLUSION: Our study outlines a comprehensive strategy to combat the increasing prevalence of T2D in both urban and rural areas. It includes promoting healthier diets to control BMI level, encouraging regular physical activity, early detection through health check-ups, tailored awareness campaigns, improving healthcare access in rural regions, stress management in urban areas, community involvement, healthcare professional training, policy advocacy like sugary drink taxation, research, and monitoring interventions. These measures collectively address the T2D challenge while accommodating the distinct features of urban and rural settings.

From erosion to epidemics: Understanding the overlapping vulnerability of hydrogeomorphic hotspots, malaria affliction, and poverty in Nigeria.

Hydrogeomorphic changes, encompassing erosion, waterlogging, and siltation, disproportionately threaten impoverished rural communities. Yet, they are often marginalized in discussions of disasters. This oversight is especially concerning as vulnerable households with limited healthcare access are most susceptible to related diseases and displacement. However, our current understanding of how these risks intersect remains limited. We explore the complex relationships between hydrogeomorphic hazards, malaria incidence, and poverty in Nigeria. Through spatial analyses we expand traditional boundaries, incorporating factors such as healthcare access, migration patterns, dam locations, demographics, and wealth disparities into a unified framework. Our findings reveal a stark reality: most residents in hydrogeomorphic hotspots live in poverty (earnings per person ≤$1.25/day), face elevated malaria risks (80 % in malaria hotspots), reside near dams (59 %), and struggle with limited healthcare access. Moreover, exposure to hydrogeomorphic hotspots could double by 2080, affecting an estimated 5.8 million Nigerians. This forecast underscores the urgent need for increased support and targeted interventions to protect those living in poverty within these hazardous regions. In shedding light on these dynamics, we expose and emphasise the pressing urgency of the risks borne by the most vulnerable populations residing in these regions-communities often characterised by limited wealth and resilience.
