Abstract
BACKGROUND Rural Australians experience higher prevalence of several chronic diseases than metropolitan Australians and are less likely to access supportive health services. This study explored associations of sociodemographic factors and barriers to support seeking for health in a sample of rural South Australians. METHODS Participants (n = 610) from three rural regions participated in a computer-assisted telephone interview (CATI), based on the Barriers to Help Seeking Scale. Each participant reported on barriers in one of three health contexts: 'general' physical health, skin cancer, and mental health. Sociodemographic factors included gender, age, highest education, region of residence, and presence of chronic conditions. Chi-squared Automatic Interaction Detection (CHAID) determined independent associations of sociodemographic factors and barrier categories (high, medium and low importance). RESULTS Privacy was a high-importance barrier in the mental health context, particularly among participants of age < 63 years. The tendency to minimise and normalise health issues was also a high-importance barrier in the mental health context. In the physical health context, those with a chronic condition were more likely to perceive normalisation as a barrier than those without a chronic condition. Need for control and self-reliance was a high-importance barrier in the mental health context and a low-importance barrier in the skin cancer context, particularly among participants < 63 years. Structural factors and distrust of providers were high-importance barriers among those who did not complete secondary education, regardless of context. CONCLUSION This study highlights the importance of a nuanced approach to promoting help-seeking in rural Australians, with message content and delivery tailored to specific health conditions and demographic circumstances.

An example of selective migration and mortality in Denmark, 1968-2017. Soc Sci Med 2021; 277:113893. [PMID: 33838450 DOI: 10.1016/j.socscimed.2021.113893] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Revised: 12/24/2020] [Accepted: 04/01/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Lolland-Falster is a rural area in south-eastern Denmark that scores unfavourable in health surveys and has the lowest life expectancy in the country. To determine the origin of poor health in Lolland-Falster, we investigated impact on mortality of long-term population movements. METHODS We used data from the Danish Central Population Register 1968-2017 to track movements in and out of Lolland-Falster. This enabled us to calculate mortality based on tenure of residence. Poisson regression adjusted for sex, 5-year age-groups, and calendar year; separately for men and women; and ages <30, 30-64 and ≥ 65 years; was reported as mortality rate ratios (MRR) with 95% confidence intervals (95% CI). RESULTS Until 1988, mortality in Lolland-Falster was fairly similar to that in the rest of Denmark. Hereafter, mortality rates drifted apart. In 2008-2017, MRR of the total Lolland-Falster population was 1.21 (95% CI: 1.19-1.23). In each 10-year calendar period, people recently in-migrating constituted about one fourth of the population. MRRs of the in-migrating population increased over time from 1.17 (95% CI: 1.08-1.26) in 1968-1977, to 1.82 (95% CI: 1.75-1.89) in 2008-2017. Persons aged 30-64 constituted the largest in-migrating group and had highest excess mortality, MRR 2.34 (95% CI: 2.19-2.50) in 2008-2017. CONCLUSION Long-term selective in-migration of vulnerable persons was behind the gradual build-up of the currently high mortality in Lolland-Falster compared to the rest of Denmark. In particular, people of working age in-migrating to Lolland-Falster contributed to this disparity.

Urban-rural differences in the prevalence and correlates of mild cognitive impairment in community-dwelling older adults in Taiwan: The EMCIT study. J Formos Med Assoc 2021; 120:1749-1757. [PMID: 33810927 DOI: 10.1016/j.jfma.2021.03.005] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 02/27/2021] [Accepted: 03/04/2021] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Taiwan is a rapidly aging society. The elderly with mild cognitive impairment (MCI) have increased risk of dementia, and this is a population-based report using standard neuropsychological tests and expert consensus diagnosis to assess the MCI prevalence and its associated factors in Taiwan. METHOD The Epidemiology of Mild Cognitive Impairment study in Taiwan (EMCIT) is a community-based, prospective cohort study. Independently-living individuals aged ≧60 years in a rural area (n = 122) and in an urban area (n = 348) of New Taipei City, Taiwan, completed detailed neuropsychological tests at the cohort baseline. Diagnosis of MCI was ascertained through expert consensus based on 2011 NIA-AA criteria. RESULTS Of 470 participants recruited between 2017 and 2019 (mean age 71.2 ± 5.4 years), the prevalence of MCI was higher in the rural area than in the urban area (25.1% vs. 10.8%, p < 0.001) after standardized for age, gender, and level of education. Having lower education and having depression symptoms were consistently associated with increased risk of MCI in both urban and rural areas (p < 0.05). Being male and diabetes were additionally associated with MCI prevalence in urban areas. CONCLUSION In this community-based prospective cohort study in Taiwan, the prevalence of MCI in the rural community was much higher than that in the urban community. Different strategies may be needed to targeted different types of communities.

Clin Nutr 2021; 40:1442-1450. [PMID: 33740513 DOI: 10.1016/j.clnu.2021.02.029] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Revised: 01/26/2021] [Accepted: 02/18/2021] [Indexed: 11/24/2022]
Abstract
Although obesity reflected by BMI can enhance the association of air pollution with increase blood pressures (BP) and prevalent hypertension in susceptible population, there remains lack evidence on interactive effects of different obesity indices and air pollutants on BP and prevalent hypertension in rural adults. 39,259 individuals were recruited from the Henan Rural Cohort. Concentrations of air pollutants (PM1, PM2.5, PM10 and NO2) were evaluated by a spatio-temporal model based on satellites data. Independent associations of air pollutants and obesity reflected by BMI, WC, WHR, WHtR, BFP and VFI on BP indicators (SBP, DBP, MAP and PP) and prevalent hypertension were analyzed by linear regression and logistic regression models, respectively. Furthermore, their additive effects were quantified by RERI, AP and S. Six obesity indices enhanced the associations of four air pollutants and BP indicators. Individuals with high PM1 concentrations plus obesity classified by BMI, WC, WHR, WHtR, BFP and VFI had a 4.18-fold (95% CI: 3.86, 4.53), 3.58-fold (95% CI: 3.34, 3.84), 3.53-fold (95% CI: 3.28, 3.81), 4.02-fold (95% CI: 3.72, 4.35), 3.89-fold (95% CI: 3.59, 4.23), 3.87-fold (95% CI: 3.62, 4.14) increase in prevalent hypertension, respectively, compared to non-obese individuals with low PM1 concentrations; similar results were observed for combined effect of PM2.5, PM10 or NO2 and obesity indices on prevalent hypertension. The significant values of RERI, AP and S indicated additive effects of air pollutants and obesity indices on hypertension. Obesity amplified the effects of exposure to high levels of air pollutants on increased BP values and prevalent hypertension, implying that obese individuals may be susceptible to elevate BP and prevalent hypertension in relation to air pollution exposure.

Recruitment planning for clinical trials with a vulnerable perinatal adolescent population using the Clinical Trials Transformative Initiative framework and principles of partner and community engagement. Contemp Clin Trials 2021; 104:106363. [PMID: 33737198 PMCID: PMC8180492 DOI: 10.1016/j.cct.2021.106363] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 03/03/2021] [Accepted: 03/13/2021] [Indexed: 12/11/2022]
Abstract
Recruitment planning is needed to establish a foundation for obesity prevention research with high risk, disadvantaged perinatal adolescent populations. In the context of developing clinical trial protocols, investigators partnered with Mississippi's Nutrition Program for Women, Infants and Children (WIC) and adopted the Clinical Trials Transformative Initiative (CTTI) framework for recruitment planning to identify and mitigate challenges to recruitment early in the clinical trial development process. The recruitment protocol consisted of 20 passive strategies grounded in principles of partner and community engagement and was flexible, accommodating, altruistic, community-focused, and minimally burdensome to partners and participants. The recruitment goal included 150 adolescent-coparticipant dyads and 145 dyads (96.7%) were successfully recruited. Investigators demonstrated the feasibility of recruiting a disadvantaged and vulnerable perinatal adolescent population that is underrepresented in health research, in one of the most persistently impoverished and poor health regions in the U.S. Four important aspects of recruitment planning using the CTTI framework are discussed including: (1) establishing partnerships with trusted community resources is a paramount investment; (2) dedicating time and resources to know and go to your community is invaluable; (3) fostering trust by offering convenient, continuous and clear communication; and (4) encouraging collaboration and participation through limiting partner and participant burden. Establishing organizational and community partnership requires a substantial amount of invaluable time and fosters recruitment success. Following the CTTI recommendations for recruitment planning led to a robust recruitment protocol that will be used in future intervention trials with an understudied perinatal adolescent population with high risk for poor maternal and fetal health outcomes.

Abstract
BACKGROUND Exposure to air pollutants (nitrogen dioxide (NO2) and particulate matters (PMs)) or physical inactivity is linked to telomere length (TL) shortening. However, there is a lack of research on combined effects of either NO2 or PMs and physical activity (PA) on TL. This study aimed to explore the joint associations of air pollutants (NO2 or PMs) and PA with relative TL in rural Chinese adults. METHODS This study was conducted among 2704 participants aged 18-79 years in rural China. Concentrations of NO2 and PMs (PM with an aerodynamics diameter ≤ 1.0 μm (PM1), ≤2.5 μm (PM2.5) or ≤10 μm (PM10)) were estimated using random forest models incorporated with satellites data, meteorological data, and land use information. Relative TL of each participant was measured by a quantitative real-time polymerase chain reaction. Linear regression models were applied to examine the independent associations between PA, NO2 or PMs and relative TL. Interaction plots were used to depict the altered associations between NO2, PM1, PM2.5, or PM10 and relative TL along with increasing PA levels. RESULTS Each 1 μg/m3 increment in NO2, PM1, PM2.5, or PM10 was associated with a 0.038 (95% confidence intervals (CI): -0.044, -0.033), 0.036 (95% CI: -0.041, -0.031), 0.052 (95% CI: -0.059, -0.045), or 0.022 (95% CI: -0.025, -0.019) decrease in relative TL among all participants; similar findings were observed among normal glucose tolerance or impaired fasting glucose (IFG) participants as well as type 2 diabetes mellitus (T2DM) patients. PA at certain levels counteracted the association of air pollutants (NO2, PM1, PM2.5, and PM10) with relative TL among IFG participants or T2DM patients. CONCLUSIONS Long-term exposure to NO2 and PMs was associated with relative TL shortening and these effects may be counteracted by PA at certain levels in IFG participants or T2DM patients.

Abstract
Although solid-fuel use or smoking is associated with obesity measured by body mass index (BMI), research on their interactive effects on general and central obesity is limited. Data of 20,140 individuals in the Henan Rural Cohort Study was examined the independent and combined associations of solid-fuel use and smoking with prevalent obesity, which was measured by BMI, waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), body fat percentage (BFP), and visceral fat index (VFI). Multiple adjusted logistic regression models showed that the OR (95% CI) of prevalent obesity measured by BMI associated with exposure to solid fuels alone or with smoking was 0.78 (0.70, 0.86) or 0.46 (0.32, 0.66), compared with neither smoking nor solid-fuel exposure. Similar results had been found in other obese anthropometric indices and in the results of linear regression analysis. The results indicated that solid-fuel use and smoking have a synergistic effect on reduction in obesity indices. The effects of household air pollution from solid-fuel use and smoking on obesity should be considered when exploring the influencing factors of obesity.

Abstract
OBJECTIVES Socio-economic status (SES) and air pollutants are thought to play an important role in human obesity. The evidence of interactive effect between SES and long-term exposure to mixture of air pollutants on obesity is limited, thus, this study is aimed to investigate their interactive effects on obesity among a rural Chinese population. METHODS A total of 38,817 individuals were selected from the Henan Rural Cohort Study. Structural equation modeling (SEM) was applied to construct the latent variables of low SES (educational level, marital status, family yearly income, and number of family members), air pollution (particulate matter with aerodynamics diameters ≤ 1.0 μm, ≤ 2.5 μm or ≤ 10 μm, and nitrogen dioxide) and obesity (body mass index, waist circumference, waist-to-hip ratio, waist-to-height ratio, body fat percentage and visceral fat index). Generalized linear regression models were used to assess associations between the constructed latent variables. Interaction plots were applied to describe interactive effect of air pollution and low SES on obesity and biological interaction indicators (the relative excess risk due to interaction (RERI), attributable proportion due to interaction (AP) and synergy index (S)) were also calculated. RESULTS Increased latent variables of low SES and mixture of air pollution were associated with a higher odds of latent variable of obesity (odds ratios (OR) (95% confidence interval (CI)) were 1.055 (1.049, 1.060) and 1.050 (1.045, 1.055)). The association of the mixture of air pollutants on obesity was aggravated by increased values of the latent variable of low SES (P < 0.001). Furthermore, the values of RERI, AP and S were 0.073 (0.051, 0.094), 0.057 (0.040, 0.073) and 1.340 (1.214, 1.479), respectively, indicating an additive effect of estimated latent variable of low SES and air pollution on obesity. CONCLUSIONS These findings suggested that low SES aggravated the negative effect of mixture of air pollutants on obesity, implying that individuals with low SES may be more susceptible to exposure to high levels of mixture of air pollutants related to increased risk of prevalent obesity.

Abstract
Background The prevalence of poor diet quality and type 2 diabetes are exceedingly high in many rural American Indian (AI) communities. Because of limited resources and infrastructure in some communities, implementation of interventions to promote a healthy diet is challenging—which may exacerbate health disparities by region (urban/rural) and ethnicity (AIs/other populations). It is critical to adapt existing evidence-based healthy food budgeting, purchasing, and cooking programs to be relevant to underserved populations with a high burden of diabetes and related complications. The Cooking for Health Study will work in partnership with an AI community in South Dakota to develop a culturally-adapted 12-month distance-learning-based healthy food budgeting, purchasing, and cooking intervention to improve diet among AI adults with type 2 diabetes. Methods The study will enroll 165 AIs with physician-diagnosed type 2 diabetes who reside on the reservation. Participants will be randomized to an intervention or control arm. The intervention arm will receive a 12-month distance-learning curriculum adapted from Cooking Matters® that focuses on healthy food budgeting, purchasing, and cooking skills. In-person assessments at baseline, month 6 and month 12 will include completion of the Nutrition Assessment Shared Resources Food Frequency Questionnaire and a survey to assess frequency of healthy and unhealthy food purchases. Primary outcomes of interest are: (1) change in self-reported intake of sugar-sweetened beverages (SSBs); and (2) change in the frequency of healthy and unhealthy food purchases. Secondary outcomes include: (1) change in self-reported food budgeting skills; (2) change in self-reported cooking skills; and (3) a mixed-methods process evaluation to assess intervention reach, fidelity, satisfaction, and dose delivered/received. Discussion Targeted and sustainable interventions are needed to promote optimal health in rural AI communities. If effective, this intervention will reduce intake of SSBs and the purchase of unhealthy foods; increase the purchase of healthy foods; and improve healthy food budgeting and cooking skills among AIs with type 2 diabetes – a population at high risk of poor health outcomes. This work will help inform future health promotion efforts in resource-limited settings. Trial registration This study was registered on ClinicalTrials.gov on October 9, 2018 with Identifier NCT03699709.

Abstract
Numerous factors, including family planning and modern contraception, disturb the potential associations between the number of children born and genetic factors in modern Western societies. The current progress of medicine and a relatively high level of well-being make it hard to test the association between children's survival rates and genetic factors in Western societies either. The goal of the current study was to reveal the possible associations between the number of children born and the number of children survived till the age of 5 y. by the time of our study with a set of six genetic polymorphisms associated with serotonin, dopamine, androgen oxytocin behavioral effects; and to test for sex-specific effects of these polymorphisms in a traditional rural sample from Arusha and Singida Districts of Northern Tanzania. The data on 965 healthy individuals (520 men and 415 women) from traditional rural communities with high reproduction profiles were collected. All participants provided information on the number of children born and survived, and other demographic information, as well as buccal epithelium samples for DNA analysis. The data were analyzed using GLM ANCOVA and the APSampler nonparametric methodology. The gene association effects on reproduction and infant survival in men and women were demonstrated. We suggest that sex differences revealed in this study are in line with sexual selection pressure on reproduction and parenting in traditional societies.

Abstract
INTRODUCTION AND OBJECTIVE The epidemiology of infection with hepatitis E virus (HEV) in Tepehuanos (a Mexican ethnic group living in rural areas) is largely unknown. This study aimed to determine the seroprevalence of and risk factors associated with HEV infection in Tepehuanos in Durango, Mexico, and to compare this seroprevalence with that in non-Tepehuanos. MATERIALS AND METHODS Through a case-control seroprevalence study, we studied 146 Tepehuanos and 146 age- and gender-matched control subjects of the general population from rural settings. The frequency of anti-HEV IgG antibodies was determined using an enzyme-linked immunoassay. Bivariate and multivariate analyses were used to assess the association between seropositivity and socio-demographic, clinical and behavioral characteristics of the Tepehuanos. RESULTS IgG antibodies against HEV were found in 5 (3.4%; 95% CI: 1.1-7.8) of 146 Tepehuanos and in 46 (31.5%; 95% CI: 24.1-39.7) of 146 control subjects (OR=0.01; 95% CI: 0.0007-0.20; P<0.000001). Bivariate analysis showed that HEV seropositivity was associated with age, consumption of meat from goat, sheep, boar, turkey and pigeon, and concrete flooring at home. However, these variables were no longer significant when analyzed by logistic regression. CONCLUSIONS This is first study on the epidemiology of HEV exposure in Tepehuanos. We demonstrated serological evidence of HEV infection in this ethnic group. The seroprevalence of HEV exposure in Tepehuanos is low as compared with that found in non-Tepehuano people living in rural Durango. Further studies to determine the risk factors associated with HEV exposure in Tepehuanos are needed.

Abstract
BACKGROUND Allergen immunotherapy (AIT) is a cost-effective treatment option in moderate-severe allergic rhino-conjunctivitis. Inequality in access to AIT and variation in compliance related to socioeconomic status or geographical location have not been described previously. OBJECTIVE The aim of the study was to evaluate access to grass pollen AIT at various educational attainment levels in the five regions of Denmark. Furthermore, grass pollen AIT treatment compliance was evaluated with respect to age, educational attainment and geographical area. METHODS The unique civil registration number of every citizen in Denmark was combined with the nationwide Danish National Health Service Prescription Database and Statistics Denmark Database to extract age, gender, residence and educational attainment of every citizen who collected prescribed AIT medication from 1998 to 2016. Then, compliance and use of AIT were calculated with respect to age, geographical location and educational attainment. RESULTS The use of subcutaneous AIT (SCIT) was significantly higher in the Capital Region; this difference was less predominant for sublingual AIT (SLIT). People who were educated only to primary school or vocational training levels were less frequent users of AIT. Compliance was especially low in the Capital Region and among people educated only to primary school level. In the age groups, compliance was similar, apart from SLIT users aged 0-9, for whom compliance was higher. CONCLUSION This nationwide study finds that SLIT has the potential to reduce inequality in access to AIT. A focus intervention is needed to facilitate access to and compliance with AIT in groups with lower socioeconomic status.

Abstract
Changes in the preconception ambient temperature (PAT) can affect the gametogenesis, disturbing the development of the embryo, but the health risks of PAT on the developing fetus are still unclear. Here, based on the National Free Preconception Health Examination Project in the rural areas of Henan Province, we evaluate the effects of PAT on preterm birth (PTB). Data of 1,231,715 records from self-reported interviews, preconception physical examination, early gestation follow-up, and postpartum follow-up were collected from 1 January 2013 to 31 December 2016. Generalized additive models were used to assess the cumulative and lag effects of PAT upon PTB. The significant cumulative effects of mean temperature within 2 weeks and 3 weeks on the risk of PTB, especially upon late PTB (34-36 weeks) (P < 0.05), were observed. Exposure to extreme heat (> 90th percentile) within 2 weeks (RR = 1.470) and 3 weeks (RR = 1.375) before conception could increase the risk of PTB. After stratifying PTB, exposure to extreme heat within 2 weeks before conception can increase the risks of early (< 34 weeks) and late PTB (P < 0.05). Besides, exposure to extreme cold (< 10th percentile) within 3 weeks or longer before conception can elevate the risk of PTB, especially late PTB. The significant lag effects of temperature changes on the risk of early PTB (lag-8 days or earlier) were observed. In conclusion, the risk of PTB was susceptible to PAT changes within 2 weeks or longer before conception. Our findings provide (i) guidance for rural couples to make pregnancy plans and (ii) scientific evidence for the government to formulate policies to prevent PTB.

[PMID: 33413290 PMCID: PMC7791824 DOI: 10.1186/s12889-020-10108-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 12/21/2020] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Lolland-Falster is a rural area of Denmark, where the life expectancy is presently almost six years lower than in the rich capital suburbs. To determine the origin of this disparity, we analysed changes in mortality during 50 years in Lolland-Falster. METHODS Annual population number and number of deaths at municipality level were retrieved from StatBank Denmark and from Statistics Denmark publications, 1968-2017. For 1974-2017, life expectancy at birth by sex and 5-year calendar period was calculated. From 1968 to 2017, standardised mortality ratio (SMR) for all-cause mortality was calculated by sex, 5-year calendar period and municipality, with Denmark as standard and including 95% confidence intervals (CI). RESULTS In 1968-2017, life expectancy in Lolland-Falster increased, but less so than in the rest of Denmark. Fifty years ago, Lolland-Falster had a mortality similar to the rest of Denmark. The increasing mortality disparity developed gradually starting in the late 1980s, earlier in Lolland municipality (western part) than in Guldborgsund municipality (eastern part), and earlier for men than for women. By 2013-2017, the SMR had reached 1.25 (95% CI 1.19-1.31) for men in the western part, and 1.11 (95% CI 1.08-1.16) for women in the eastern part. Increasing mortality disparity was particularly seen in people aged 20-69 years. CONCLUSIONS This study is the first to report on increasing geographical segregation in all-cause mortality in a Nordic welfare state. Development of the mortality disparity between Lolland-Falster and the rest of Denmark followed changes in agriculture, industrial company closure, a shipyard close-down, administrative centralisation, and a decreasing population size.

Abstract
OBJECTIVES This study was performed to identify the effect of physical activity at work on obesity and to analyze the contribution of socioeconomic factors and health behaviors to this association, which has been relatively little studied. METHODS From the Korean National Cancer Center Community Cohort, a total of 5,587 adults (2,125 men; 3,462 women) aged more than 30 years living in rural areas were enrolled. Information on socio-demographic factors, health behaviors, and body mass index was gathered using face-to-face interviews and measurements of height and weight. RESULTS Inverse associations were identified between vigorous-intensity physical activity at work and obesity in both men and women, while no association was found between vigorous-intensity physical activity during leisure time and obesity. High household income was independently associated with a lower risk of obesity among those who had low levels of vigorous-intensity physical activity at work. Vigorous physical activity at work showed an inverse association with obesity in rural areas where heavy manual labor is common. CONCLUSIONS Our findings indicate the necessity to account for various types of physical activity to improve the assessment and prevention of obesity.

Association of long-term exposure to ambient air pollutants with prolonged sleep latency: The Henan Rural Cohort Study. ENVIRONMENTAL RESEARCH 2020; 191:110116. [PMID: 32846171 DOI: 10.1016/j.envres.2020.110116] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2020] [Revised: 08/09/2020] [Accepted: 08/10/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND Prolonged sleep latency is associated with far-reaching public health consequences. Although evidence about the effect of air pollution on sleep problem has been shown, the effect on sleep latency remained unknown. The study aimed to analyze the association between long-term exposure to air pollution and prolonged sleep latency in rural China. METHODS In all, 27935 participants were included in the study from Henan Rural Cohort Study. A satellite-based spatiotemporal model was used to evaluate the 3-year average concentration of air pollutants at the home address of participants before the baseline survey. Air pollutants included NO2 (nitrogen dioxide), PM1 (particulate matter with aerodynamic diameters ≤1 μm), PM2.5 (particulate matter with aerodynamic diameters ≤ 2.5 μm), and PM10 (particulate matter with aerodynamic diametes ≤ 10 μm). A logistic regression model was conducted to assess the odds ratio (OR) and 95% confidence interval (95% CI) between air pollutants and prolonged sleep latency. RESULTS There were 5825 (20.85%) participants with prolonged sleep latency. The average concentration of NO2, PM1, PM2.5, and PM10 were 38.22 (2.54) μg/m3, 56.29 (1.75) μg/m3, 72.30 (1.87) μg/m3, and 130.01 (4.58) μg/m3. The odds ratio (95%CI) of prolonged sleep latency with an IQR increase of NO2, PM1, PM2.5, and PM10 were 1.59 (1.33-1.90), 1.23 (1.13-1.33), 1.28 (1.13-1.45) and 1.43 (1.22-1.67). The stratified analysis showed the effect of air pollutants was stronger among those with stroke. CONCLUSION Long-term exposure to NO2, PM1, PM2.5 and PM10 were associated with prolonged sleep latency. The adverse impact of air pollution should be considered when treating sleep problems.

BMC Infect Dis 2020; 20:904. [PMID: 33256645 PMCID: PMC7706037 DOI: 10.1186/s12879-020-05646-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Accepted: 11/22/2020] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Tuberculosis (TB) is a major human threat, as evidenced by the large numbers of cases and deaths, particularly in developing countries with poor economic and educational statuses. Myanmar has one of the highest TB burdens in the world, but no TB information is available for people living in the rural northeastern regions of Myanmar. The present study estimated the prevalence of TB and identified factors associated with TB infection in people living in rural communities in Shan State. METHODS A cross-sectional study was performed to gather information from participants. People aged 18-59 years who lived in the three areas with the highest numbers of TB cases in Shan State in northeastern Myanmar were included in the study population. A simple random method was used to select the sample from the villages. A validated questionnaire was used for data collection in face-to-face interviews after obtaining signed informed consent from the selected participants. The Mantoux tuberculin skin test (TST) was administered to detect TB infection, and a result that was 10 mm or greater after 48 h was considered positive. Chi-squared tests and logistic regression were used to identify the associations between the variables at a significance level of α = 0.05. RESULTS A total of 303 participants were recruited for the study; 64.7% were females, and the mean age was 37 years (SD = 12.5). Most participants were Burmese (25.4%), and 14.95% were Shan. Sixty-three participants (20.8%) had a positive TST. Four variables were associated with TB infection in the multivariate model. Males had a greater chance of TB infection than females (AOR = 2.51; 95% CI = 1.32-4.76). Participants who were ever married had a greater chance of TB infection than participants who were single (AOR = 3.93; 95% CI = 1.18-13.00). Participants who used wood and charcoal as their main sources of energy for cooking had a greater chance of TB infection than participants who used electricity (AOR = 4.23; 95% CI = 1.25-9.64). Participants who had a low level of TB prevention and care knowledge had a greater chance of TB infection than participants with a high level of TB prevention and care knowledge (AOR = 4.49; 95% CI = 1.88-10.72). CONCLUSIONS Public health programs that focus on improving knowledge of TB prevention and care and avoiding the use of wood and charcoal as the primary sources of energy for cooking, particularly in males and ever-married individuals, are urgently needed.

Abstract
BACKGROUND Most studies among Hispanics have focused on individual risk factors of obesity, with less attention on interpersonal, community and environmental determinants. Conducting community based surveys to study these determinants must ensure representativeness of disparate populations. We describe the use of a novel Geographic Information System (GIS)-based population based sampling to minimize selection bias in a rural community based study. METHODS We conducted a community based survey to collect and examine social determinants of health and their association with obesity prevalence among a sample of Hispanics and non-Hispanic whites living in a rural community in the Southeastern United States. To ensure a balanced sample of both ethnic groups, we designed an area stratified random sampling procedure involving three stages: (1) division of the sampling area into non-overlapping strata based on Hispanic household proportion using GIS software; (2) random selection of the designated number of Census blocks from each stratum; and (3) random selection of the designated number of housing units (i.e., survey participants) from each Census block. RESULTS The proposed sample included 109 Hispanic and 107 non-Hispanic participants to be recruited from 44 Census blocks. The final sample included 106 Hispanic and 111 non-Hispanic participants. The proportion of Hispanic surveys completed per strata matched our proposed distribution: 7% for strata 1, 30% for strata 2, 58% for strata 3 and 83% for strata 4. CONCLUSION Utilizing a standardized area based randomized sampling approach allowed us to successfully recruit an ethnically balanced sample while conducting door to door surveys in a rural, community based study. The integration of area based randomized sampling using tools such as GIS in future community-based research should be considered, particularly when trying to reach disparate populations.

Social participation needs of older adults living in a rural regional county municipality: toward reducing situations of isolation and vulnerability. BMC Geriatr 2020; 20:456. [PMID: 33160305 PMCID: PMC7648429 DOI: 10.1186/s12877-020-01849-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Accepted: 10/26/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Social participation is restricted for approximately half the older adult population but is critical in fostering community vitality, promoting health, and preventing disabilities. Although targeted through interventions by community organizations, healthcare professionals and municipalities, little is known about the needs of older adults to participate socially, especially in rural areas. This study thus aimed to identify and prioritize the social participation needs of older adults living in a rural regional county municipality. METHODS A participatory action research was conducted in a rural regional county municipality (RCM) in Quebec, Canada, with a convenience sample of 139 stakeholders, including older adults, caregivers, healthcare and community organization managers, healthcare and community organization workers, community partners and key informants. RESULTS Facilitators and barriers to social participation are related to personal factors (e.g., health, interests, motivation), the social environment (e.g., availability of assistance or volunteers) and the physical environment (e.g., distance to resources, recreational facilities and social partners). Nine older adults' needs emerged and were prioritized as follows: 1) having access to and being informed about transportation options, 2) being informed about available activities and services, 3) having access to activities, including volunteering opportunities, suited to their interests, schedule, cost, language and health condition, 4) being accompanied to activities, 5) having access to meeting places near home and adapted to their health condition, and 6-9 (no preferred order) being reached when isolated, being personally invited and welcomed to activities, having a social support network, and being valued and recognized. Differences emerged when prioritizing needs of older adults with disabilities (greater need for assistance, accessibility and adapted activities) and older adults living in a rural area (greater need for transportation). CONCLUSIONS To promote active participation in the community, the social participation needs of older women and men living in rural areas must be addressed, especially in regard to transportation, information, adapted activities, assistance and accessibility. The first part of this action research will be followed by community selection and implementation of initiatives designed to ultimately foster their social participation.

Abstract
BACKGROUND Epilepsy affects at least 50 million individuals worldwide, especially in sub-Saharan Africa (sSA). Cognitive impairment is common in people with epilepsy (PWE) yet, little is known on the burden of cognitive impairment in people with epilepsy in sSA. This study was thus designed to assess cognitive impairment in PWE or epilepsy-associated neurocognitive disorders (EAND) in a rural population in Cameroon. METHODS This was a case-control study including PWE and age/sex-matched healthy controls from July to September 2017 in Bilomo, a village in the Mbam and Kim Division. The Montreal Cognitive Assessment (MoCA), International HIV Dementia Scale (IHDS), Dubois' Five Word testing, Frontal Assessment Battery (FAB), Isaac's Set Test and the Clock drawing test were administered to the study participants to evaluate global and specific cognitive functions. RESULTS Eighty participants were included (40 cases and 40 controls) with a mean age of 25.78 years. Using the MoCA, 87.5% of cases had cognitive impairment, against 37.5% of controls (p < 0.001; OR 11.67; CI 3.40-45.09). Using the IHDS, the prevalence of global cognitive impairment was 84.6% among the cases against 40% for the controls (p = <0.001; OR 7.07; CI 2.29-29.19). Specifically, executive function deficits (92.5% of cases vs 40.0% of controls p = <0.001 OR = 18.50 CI; 4.48-105.08) and decreased verbal fluency (100% of cases against 45% of controls p < 0.001) were the most affected cognitive domains. Longer duration of epilepsy and higher seizure frequency were associated with global cognitive impairment. Low level of education was associated with both decreased verbal fluency and executive dysfunction while a longer stay in Bilomo correlated with poor results on the Isaac's Set Test. CONCLUSION The prevalence of cognitive impairment appears to be much higher in PWE in the Mbam valley, particularly decreased executive function and verbal fluency, than in people without epilepsy. Longer disease duration, higher seizure frequency, low level of education and length of stay in Bilomo are associated with poorer cognitive performance. More studies are needed to refine evaluation tools to better characterize and manage EAND in sSA.

Abstract
BACKGROUND Long-term exposure to air pollutants relate to increase risk of cardiovascular diseases that may be partially attributable to platelet dysfunction. Physical activity (PA) may attenuate inflammation to modulate platelet function. Thus, this study aimed to evaluate associations of air pollutants and PA with platelet traits of cardiovascular risk. METHODS A total of 31,282 participants were obtained from the Henan Rural Cohort (n = 39,259). The concentrations of particulate matter (PM) (PM with an aerodynamic diameter ≤1.0 μm (PM1), ≤2.5 μm (PM2.5), or ≤10 μm (PM10)) and nitrogen dioxide (NO2) were evaluated by using a spatiotemporal model incorporated into satellites data. Independent and combined effects of air pollutants and PA on platelet traits were analyzed by linear mixed models. RESULTS Positive associations of PM1, PM2.5, PM10 and NO2 with platelet indices (mean platelet volume (MPV), platelet distribution width (PDW) and platelet large cell ratio (P-LCR), the MPV to platelet counts (PLT) ratio (MPVP)) were observed, whereas negative associations of PM10 and NO2 with PLT or plateletcrit (PCT) were observed; negative interaction effects of PM2.5 PM10 and NO2 and PA on MPV, PDW or P-LCR were found; negative interaction effects of PM1, PM2.5 and PM10 and PA on PCT were observed. CONCLUSIONS Long-term exposure to air pollutants were related to increase platelet size and these associations were attenuated by increased PA, implying that PA is a costless and affordable method to decrease adverse effects on platelet traits in relation to air pollutants.

Abstract
Validity of PHQ-2 to screen for depression was assessed in an agricultural population in Chile. The sample included 4767 adults enrolled from 2014 to 2017 in a population-based cohort of chronic disease in Maule, Chile. Receiver operating characteristic (ROC) curve analysis was used to find the optimal PHQ-2 cut-off for depression, defined as the highest Youden index, using PHQ-9 as a reference standard. Sensitivity, specificity, and Youden J index were calculated for every cut-off point of PHQ-2. Prevalence of depression measured by PHQ-9 and PHQ-2 was 18% and 18.4%, respectively. Corresponding rates for women were 24.7% and 23.6%, and 8.3% and 10.9 for men. The optimal PHQ-2 cut-off score was 3, achieved with a sensitivity of 74.6%, specificity 93.9%, and Youden index of 0.68. The area under the curve for the ROC analysis ROC curve was 0.92 (95% CI 0.91-0.93). PHQ-2 has good performance for use as a test for depression screening in a rural population of Chile and can be easily applied in areas with low resources.

Abstract
PURPOSE This study explored rural-urban differences in meeting physical activity (PA) recommendations and health status in cancer survivors in central Pennsylvania and associations between PA and health status. METHODS Cancer survivors (N = 2463) were identified through a state cancer registry and mailed questionnaires assessing PA and health status. Rural-urban residence was based on county of residence at diagnosis. Participants self-reported frequency and duration of leisure-time PA and were classified as meeting: (1) aerobic recommendations (≥ 150 min/week), (2) muscle-strengthening recommendations (≥ 2 times/week), (3) both aerobic and muscle-strengthening recommendations, or (4) neither recommendation. Logistic regression models examined associations between rural-urban residence and meeting PA recommendations and associations between PA and health status, adjusting for age, cancer type, gender, and income. RESULTS Nearly 600 (N = 591, 24.0%) cancer survivors returned completed questionnaires (rural 9.5%, urban 90.5%). Half (50.0%) of rural cancer survivors reported no leisure-time PA compared to 35.2% of urban cancer survivors (p = 0.020), and urban cancer survivors were 2.6 times more likely to meet aerobic PA recommendations (95% CI 1.1-6.4). Odds of reporting good physical and mental health were 2.3 times higher among survivors who reported meeting aerobic recommendations compared to those who did not meet PA recommendations (95% CI 1.1-4.5), adjusting for rurality and covariates. CONCLUSIONS Results demonstrate persistent rural-urban differences in meeting PA recommendations in cancer survivors and its association with self-reported health. IMPLICATIONS FOR CANCER SURVIVORS Findings underscore the need for interventions to increase PA in rural cancer survivors in an effort to improve health status and reduce cancer health disparities.

Abstract
The burden of influenza in rural areas is largely unstudied. Rural populations may be vulnerable yet isolated from circulating virus. Laboratory-confirmed influenza hospitalizations in rural Colorado census tracts over eight influenza seasons were inconsistently distributed across seasons. Rural rates were, on average, lower than urban rates. Race, ethnicity, poverty, health insurance coverage, and distance from a hospital accounted for rate differences. Our interpretation is: 1) influenza regularly circulates in urban areas and inconsistently spreads to rural areas, 2) demographic and socioeconomic factors drive morbidity in exposed populations, and 3) public health interventions targeting high-risk urban census tracts may be beneficial.
