The Role of Suburbanization in Metropolitan Segregation After 1940.

The three decades from 1940 through 1970 mark a turning point in the spatial scale of Black-White residential segregation in the United States compared with earlier years. We decompose metropolitan segregation into three components: segregation within the city, within the suburbs, and between the city and its suburbs. We then show that extreme levels of segregation were well established in most cities by 1940, and they changed only modestly by 1970. In this period, changes in segregation were greater at the metropolitan scale, driven by racially selective population growth in the suburbs. We also examine major sources of rising segregation, including region, metropolitan total, and Black population sizes, and indicators of redlining in the central cities based on risk maps prepared by the Home Owners Loan Corporation (HOLC) in the late 1930s. In addition to overall regional differences, segregation between the city and suburbs and within suburbia increased more in metropolitan areas with larger Black populations, but this relationship was found only in the North. In contrast to some recent theorizing, there is no association between preparation of an HOLC risk map or the share of city neighborhoods that were redlined and subsequent change in any component of segregation.

Health literacy and quality of life among people in semi-urban and urban areas / Letramento em saúde e qualidade de vida entre pessoas em áreas semiurbanas e urbanas / Alfabetización en salud y calidad de vida entre personas en áreas semiurbanas y urbanas

Abstract Objective: to investigate health literacy level, quality of life and related factors in semi-urban and urban areas. Method: this cross-sectional study was carried out between December 2018 and February 2019 with 595 participants. The variables found significant in the bivariate regression analysis were included in the multivariate regression analysis. Results: according to the scores obtained from the Health Literacy Scale, participants' health literacy 76.5% levels were adequate. The factors affecting the Health Literacy Scale score in semi-urban areas were educational status, income status, presence of a chronic disease, perceived health, and understanding the health information provided. The factors affecting the Health Literacy Scale score in urban areas were age, marital status, reading habits, presence of a chronic disease, and understanding the health information provided (p < .05). There was a statistically significant difference between participants living in semi-urban and urban areas in terms of their health literacy and quality of life levels (p < .001). Conclusion: the health literacy level was inadequate in three out of ten participants, and it was even lower in semi-urban areas.

A novel wastewater-based epidemiology indexing method predicts SARS-CoV-2 disease prevalence across treatment facilities in metropolitan and regional populations.

There is a need for wastewater based epidemiological (WBE) methods that integrate multiple, variously sized surveillance sites across geographic areas. We developed a novel indexing method, Melvin's Index, that provides a normalized and standardized metric of wastewater pathogen load for qPCR assays that is resilient to surveillance site variation. To demonstrate the utility of Melvin's Index, we used qRT-PCR to measure SARS-CoV-2 genomic RNA levels in influent wastewater from 19 municipal wastewater treatment facilities (WWTF's) of varying sizes and served populations across the state of Minnesota during the Summer of 2020. SARS-CoV-2 RNA was detected at each WWTF during the 20-week sampling period at a mean concentration of 8.5 × 104 genome copies/L (range 3.2 × 102-1.2 × 109 genome copies/L). Lag analysis of trends in Melvin's Index values and clinical COVID-19 cases showed that increases in indexed wastewater SARS-CoV-2 levels precede new clinical cases by 15-17 days at the statewide level and by up to 25 days at the regional/county level. Melvin's Index is a reliable WBE method and can be applied to both WWTFs that serve a wide range of population sizes and to large regions that are served by multiple WWTFs.

Community-based point-of-care testing to identify new HIV infections: A cross-sectional study from Pune, India.

ABSTRACT: The World Health Organization recommends point-of-care testing (POCT) to detect human immunodeficiency virus (HIV) infected individuals in the community. This will help improve treatment coverage through detection of HIV infection among those who are unaware of their status.This study was planned with an objective to investigate the feasibility and acceptability of POCT for HIV in the community.A community-based cross-sectional study was conducted in rural and peri-urban areas of Pune, India. These sites were selected based on the distance from the nearest HIV testing center. Testing locations were identified in consultation with the local stakeholders and grass-root health workers to identify and capture the priority population. The POCT was performed on blood samples collected by the finger-prick method.The proportion of participants seeking HIV tests for the first time was 79.6% that signifies the feasibility of POCT. The acceptability in the peri-urban and rural areas was 70.2% and 69.7%, respectively. POCT was performed at construction sites (24.9%), nearby industries (16.1%) and parking areas of long-distance trucks (8.1%) in the peri-urban area. Three newly diagnosed HIV-infected participants (0.1%) were detected from the peri-urban areas but none from the rural areas. Two of the newly diagnosed participants and their spouses were linked to care.There was a high acceptability of POCT and wider coverage of priority population with a strategy of testing at places preferable to the study population. Therefore, we believe that community-based POCT is a promising tool for improving HIV testing coverage even in low prevalence settings with the concentrated HIV epidemic.

2020 COVID-19 lockdown and the impacts on air quality with emphasis on urban, suburban and rural zones.

Air quality improvements pollution changes due to COVID-19 restrictions have been reported for many urban developments and large metropolitan areas, but the respective impacts at rural and remote zones are less frequently analysed. This study evaluated air pollution changes across all Portugal (68 stations) considering all urban, suburban and rural zones. PM10, PM2.5, NO2, SO2, ozone was analysed in pre-, during, and post-lockdown period (January-May 2020) and for a comparison also in 2019. NO2 was the most reduced pollutant in 2020, which coincided with decreased traffic. Significant drop (15-71%) of traffic related NO2 was observed specifically during lockdown period, being 55% for the largest and most populated region in country. PM was affected to a lesser degree (with substantial differences found for largely populated areas (Lisbon region ~ 30%; North region, up to 49%); during lockdown traffic-related PM dropped 10-70%. PM10 daily limit was exceeded 50% less in 2020, with 80% of exceedances before lockdown period. SO2 decreased by 35%, due to suspended industrial productions, whereas ozone concentrations slightly (though not significantly) increased (83 vs. 80 µg m-3).

The Effects of Host Availability and Fitness on Aedes albopictus Blood Feeding Patterns in New York.

Aedes albopictus is a competent vector of numerous pathogens, representing a range of transmission cycles involving unique hosts. Despite the important status of this vector, variation in its feeding patterns is poorly understood. We examined the feeding patterns of Ae. albopictus utilizing resting collections in Long Island, NY, and contextualized blood meal sources with host availability measured by household interviews and camera traps. We identified 90 blood meals, including 29 humans, 22 cats, 16 horses, 12 opossums, 5 dogs, 2 goats, and 1 each of rabbit, rat, squirrel, and raccoon. This is only the third study of Ae. albopictus blood feeding biology that quantitatively assessed domestic host availability and is the first to do so with wild animals. Host feeding indices showed that cats and dogs were fed upon disproportionately often compared with humans. Forage ratios suggested a tendency to feed on cats and opossums and to avoid raccoons, squirrels, and birds. This feeding pattern was different from another published study from Baltimore, where Ae. albopictus fed more often on rats than humans. To understand whether these differences were because of host availability or mosquito population variation, we compared the fitness of New York and Baltimore Ae. albopictus after feeding on rat and human blood. In addition, we examined fitness within the New York population after feeding on human, rat, cat, horse, and opossum blood. Together, our results do not indicate major mosquito fitness differences by blood hosts, suggesting that fitness benefits do not drive Northeastern Ae. albopictus feeding patterns.

Incidence of grinspan syndrome among tribal and suburban population of Maharashtra - A cross sectional study.

BACKGROUND: Grinspan syndrome is characterised by presence of the triad: hypertension, diabetes mellitus (DM) and oral lichen planus (OLP). OLP, seen in hypertension and diabetes mellitus, is caused by drugs used to treat these diseases according to literature, however the incidence of this syndrome in India has not yet been reported anywhere. Hence the present study was conducted with the following objectives: (i) To determine the incidence of Grinspan syndrome amongst tribal and suburban study population of Maharashtra in different gender and age groups (ii) To correlate occurrence of OLP with DM type 2 and hypertension (iii) To find out the number of patients with OLP, DM type 2 and hypertension either alone or in combination. METHODS AND MATERIAL: The present study was conducted on 4681 new patients attending the routine outpatient department (O.P.D.) of the dental hospital between January 2017 and December 2018. Patients with OLP or DM (type-2) or hypertension or any combination of these diseases were included in the present study. Brief case history of each patient was recorded. Data thus collected were analysed using SPSS version 20 for Chi-square test. RESULTS: Grinspan syndrome was found in 1.62% of the study population. Syndrome was seen in 1.02% of female and 0.59% of male. Maximum patient affected by syndrome were in 35-50 years of age group. CONCLUSIONS: Incidence of Grinspan syndrome was 1.62%, mainly seen in sub-urban females of 35-50 years and OLP seen in hypertension and diabetes mellitus has different etiology and is not caused by drugs used to treat these diseases.

Seroprevalence of SARS-CoV-2, Symptom Profiles and Sero-Neutralization in a Suburban Area, France.

The World Health Organisation recommends monitoring the circulation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We investigated anti-SARS-CoV-2 total immunoglobulin (IgT) antibody seroprevalence and in vitro sero-neutralization in Nancy, France, in spring 2020. Individuals were randomly sampled from electoral lists and invited with household members over 5 years old to be tested for anti-SARS-CoV-2 (IgT, i.e., IgA/IgG/IgM) antibodies by ELISA (Bio-rad); the sero-neutralization activity was evaluated on Vero CCL-81 cells. Among 2006 individuals, the raw seroprevalence was 2.1% (95% confidence interval 1.5 to 2.9), was highest for 20- to 34-year-old participants (4.7% (2.3 to 8.4)), within than out of socially deprived area (2.5% vs. 1%, p = 0.02) and with than without intra-family infection (p < 10-6). Moreover, 25% of participants presented at least one COVID-19 symptom associated with SARS-CoV-2 positivity (p < 10-13), with highly discriminant anosmia or ageusia (odds ratio 27.8 [13.9 to 54.5]); 16.3% (6.8 to 30.7) of seropositive individuals were asymptomatic. Positive sero-neutralization was demonstrated in vitro for 31/43 seropositive subjects. Regarding the very low seroprevalence, a preventive effect of the lockdown in March 2020 can be assumed for the summer, but a second COVID-19 wave, as expected, could be subsequently observed in this poorly immunized population.

The use of herbal and dietary supplement among community-dwelling elderly in a suburban town of Malaysia.

BACKGROUND: The use of herbal and dietary supplement (HDS) in health and disease management has gained global attention. HDS are generally accepted by the public and are associated with positive health behaviours. However, several reports have been documented with regards to their potential adverse effects and interaction with conventional medicines. Limited data is currently available on the use of HDS among elderly population in Malaysia. This present study aims to investigate the prevalence of and pattern of HDS use among a sample of community-dwelling elderly in a suburban town in Malaysia. METHODS: A cross-sectional survey was conducted between March and May 2019 among the elderly aged ≥60 years old. The participants with the following criteria were included in the study: aged ≥60 years, residing in Puncak Alam and able to understand Malay or English language. Data were collected using a pre-validated questionnaire. All statistical analysis was conducted using IBM SPSS ver. 23. RESULTS: Overall, 336 out of 400 elderly responded to the survey, achieving a response rate of 84%. This study observed that almost 50% of the respondents were using at least one type of HDS in the past one month of the survey. Among HDS non-users, most of them preferred to use modern medicines (62.6%, 114/182). Among the HDS users, 75.3% (116/154) were using at least one type of modern medicine (prescription or over-the-counter medicine). Multivariate analysis showed that having good to excellent perceived health (adjusted OR = 2.666, 95% CI = 1.592-4.464), having felt sick at least once in the past one month (adjusted OR = 2.500, 95% CI = 1.426-4.383), and lower body mass index (adjusted OR = 0.937, 95% CI = 0.887-0.990) were associated with HDS use. It was noted that only a small percentage of HDS users (16.2%, 25/154) had informed healthcare providers on their HDS use. CONCLUSION: The use of HDS is common among the elderly sampled. Hence, healthcare providers should be more vigilant in seeking information of HDS use for disease management in their elderly patients. Campaigns that provide accurate information regarding the appropriate use of HDS among the elderly are pertinent to prevent misinformation of the products.

Household food insecurity and its association with self-reported male perpetration of intimate partner violence: a survey of two districts in central and western Uganda.

OBJECTIVES: This study aimed to determine the lifetime prevalence of male-perpetrated intimate partner violence (IPV), and to assess the association with food insecurity, sociodemographic factors and health risk behaviours in Uganda in the year preceding COVID-19-associated lockdowns. DESIGN: Population-based, cross-sectional household survey. SETTING: Urban, semiurban and rural communities of the Wakiso and Hoima districts in Uganda. PARTICIPANTS: A total of N=2014 males aged 13-80 years participated in the survey. The current study included males who reported having ever been in a sexual union and responded to the IPV questions (N=1314). MEASURES: Data were collected face-to-face from May 2018 to July 2019 using an interviewer-mediated questionnaire. Lifetime IPV perpetration was measured as 'no physical and/or sexual IPV', 'physical' versus 'sexual violence only', and 'physical and sexual violence'. Past-year food insecurity was measured through the Food Insecurity Experience Scale and categorised into 'none', 'low' and 'high'. Multinomial logistic regression was used to determine the crude and adjusted relative risk ratios (aRRRs) of IPV perpetration in relation to self-reported food insecurity, adjusting for sociodemographic and health risk behaviours. RESULTS: The prevalence of self-reported lifetime IPV perpetration was 14.6% for physical and 6.5% for sexual violence, while 5.3% reported to have perpetrated both physical and sexual IPV. Most (75.7%) males reported no food insecurity, followed by low (20.7%) and high (3.6%) food insecurity. In adjusted models, food insecurity was associated with increased risk of having perpetrated both physical and sexual violence (aRRR=2.57, 95% CI 1.52 to 4.32). IPV perpetration was also independently associated with having had more than one lifetime sexual partner and drinking alcohol, but not with education level or religion. CONCLUSION: This study suggests that food insecurity is associated with male IPV perpetration, and more efforts are needed to prevent and mitigate the expected worsening of this situation as a result of the COVID-19 pandemic.

Needs and resources of people with type 2 diabetes in peri-urban Cochabamba, Bolivia: a people-centred perspective.

BACKGROUND: The rising prevalence of type 2 diabetes results in a worldwide public healthcare crisis, especially in low- and middle-income countries (LMICs) with unprepared and overburdened health systems mainly focused on infectious diseases and maternal and child health. Studies regarding type 2 diabetes in LMICs describe specific interventions ignoring a comprehensive analysis of the local factors people see influential to their health. This study aims to meet this research gap by exploring what people with type 2 diabetes in Bolivia need to maintain or improve their health, how important they perceive those identified needs and to what extent these needs are met. METHODS: From March until May 2019, 33 persons with type 2 diabetes from three periurban municipalities of the department of Cochabamba participated in this study. The concept mapping methodology by Trochim, a highly structured qualitative brainstorming method, was used to generate and structure a broad range of perspectives on what the participants considered instrumental for their health. RESULTS: The brainstorming resulted in 156 original statements condensed into 72 conceptually different needs and resources, structured under nine conceptual clusters and four action domains. These domains illustrated with vital needs were: (1) self-management with use of plants and the possibility to measure sugar levels periodically; (2) healthcare providers with the need to trust and receive a uniform diagnosis and treatment plan; (3) health system with opportune access to care and (4) community with community participation in health and safety, including removal of stray dogs. CONCLUSIONS: This study identifies mostly contextual factors like low literacy levels, linguistic problems in care, the need to articulate people's worldview including traditional use of natural remedies with the Bolivian health system and the lack of expertise on type 2 diabetes by primary health care providers. Understanding the needs and structuring them in different areas wherein action is required serves as a foundation for the planning and evaluation of an integrated people centred care program for people with type 2 diabetes. This participative method serves as a tool to implement the often theoretical concept of integrated people centred health care in health policy and program development.

RESUMEN: ANTECEDENTES: La creciente prevalencia de la diabetes tipo 2 resulta en una crisis mundial de salud pública, especialmente en países de ingresos bajos y medianos (PIBM) con sistemas de salud no preparados y sobrecargados, centrados principalmente en las enfermedades infecciosas y la salud materno infantil. Los estudios sobre la diabetes tipo 2 en los PIBM describen intervenciones específicas ignorando un análisis exhaustivo de los factores locales que las personas consideran influyen en su salud. Este estudio tiene como objetivo cubrir esta brecha de investigación al explorar lo que las personas con diabetes tipo 2 en Bolivia necesitan para mantener o mejorar su salud, qué tan importante perciben esas necesidades identificadas y en qué medida estas necesidades son satisfechas. MéTODOS: De marzo a mayo de 2019, 33 personas con diabetes tipo 2 de tres municipios periurbanos del departamento de Cochabamba participaron en este estudio. Se utilizó la metodología de mapeo conceptual de Trochim, un método de lluvia de ideas cualitativo altamente estructurado, para generar y estructurar una amplia gama de perspectivas sobre lo que los participantes consideraron herramientas para su salud. RESULTADOS: La lluvia de ideas resultó en 156 enunciaciones originales condensadas en 72 necesidades y recursos conceptualmente diferentes, estructurados en nueve grupos conceptuales y cuatro dominios de acción. Estos dominios ilustrados con necesidades vitales fueron: (1) autogestión con el uso de plantas y la posibilidad de medir los niveles de azúcar periódicamente; (2) proveedores de salud con la necesidad de confiar y recibir un diagnóstico y plan de tratamiento uniforme; (3) sistema de salud con acceso oportuno a la atención y (4) comunidad con participación comunitaria en salud y seguridad, incluida el control de perros callejeros. CONCLUSIONES: Este estudio identifica principalmente factores contextuales como bajos niveles de alfabetización, problemas lingüísticos en la atención, la necesidad de articular la cosmovisión de las personas incluyendo el uso tradicional de remedios naturales con el sistema de salud boliviano y la falta de pericia en diabetes tipo 2 por parte de los proveedores de atención primaria de salud. Comprender las necesidades y estructurarlas en diferentes áreas en las que se requiere actuar, sirve como base para la planificación y evaluación de un programa de atención integral centrada en la persona para personas con diabetes tipo 2. Este método participativo sirve como una herramienta para implementar el concepto, a menudo teórico, de atención integrada centrada en las personas en el desarollo de políticas y programas de salud.

Value of simple clinical parameters to predict insulin resistance among newly diagnosed patients with type 2 diabetes in limited resource settings.

BACKGROUND: Insulin resistance (IR) has been considered as a therapeutic target in the management of type 2 diabetes mellitus (T2DM). Readily available, simple and low cost measures to identify individuals with IR is of utmost importance for clinicians to plan optimal management strategies. Research on the associations between surrogate markers of IR and routine clinical and lipid parameters have not been carried out in Sri Lanka, a developing country with rising burden of T2DM with inadequate resources. Therefore, we aimed to study the utility of readily available clinical parameters such as age, body mass index (BMI), waist circumference (WC) and triglyceride to high density lipoprotein cholesterol ratio (TG/HDL-C) in the fasting lipid profile in predicting IR in a cohort of patients with newly diagnosed T2DM in Sri Lanka. METHODS AND FINDINGS: We conducted a community based cross sectional study involving of 147 patients (age 30-60 years) with newly diagnosed T2DM in a suburban locality in Galle district, Sri Lanka. Data on age, BMI, WC, fasting plasma glucose (FPG) concentration, fasting insulin concentration and serum lipid profile were collected from each subject. The indirect IR indices namely homeostasis model assessment (HOMA), quantitative insulin sensitivity check index (QUICKI) and McAuley index (MCA) were estimated. Both clinical and biochemical parameters across the lowest and the highest fasting insulin quartiles were compared using independent sample t-test. Linear correlation analysis was performed to assess the correlation between selected clinical parameters and indirect IR indices. The area under the receiver operating characteristic (ROC) curve was obtained to calculate optimal cut-off values for the clinical markers to differentiate IR. BMI (p<0.001) and WC (p = 0.01) were significantly increased whereas age (p = 0.06) was decreased and TG/HDL-C (p = 0.28) was increased across the insulin quartiles. BMI and WC were significantly correlated (p<0.05) with HOMA, QUICKI and MCA. Out of the clinical parameters, age showed a borderline significant correlation with QUICKI and TG/HDL-C showed a significant correlation only with MCA. The area under ROC of BMI was 0.728 (95% CI 0.648-0.809; p<0.001) and for WC, it was 0.646 (95% CI 0.559-0.734; p = 0.003). The optimized cut-off value for BMI and WC were 24.91 kg/m2 and 81.5 cm respectively to differentiate the patients with IR or ID. Study limitations include small sample size due to recruitment of patients only from a limited geographical locality of the country and not totally excluding of the possibility of inclusion of some patients with slowly progressive type 1 DM or Latent onset diabetes of adulthood from the study population. CONCLUSIONS: The results revealed that there was a significant positive correlation between BMI, WC and HOMA while a significant negative correlation with QUICKI and MCA among the cohort of patients with newly diagnosed T2DM. The cut-off values of BMI and WC as 24.91 kg/m2 and 81.5 cm respectively could be used as simple clinical parameters to identify IR in newly diagnosed patients with T2DM. Our results could be beneficial in rational decision making in the management of newly diagnosed patients with T2DM in limited resource settings.

Cannabis use, use frequency, and use disorder in large metropolitan, small metropolitan, and nonmetropolitan areas.

BACKGROUND: Despite significant geographical heterogeneity of sociodemographic and clinical characteristics, little is known about potential differences in cannabis use behaviors in U.S. geographic areas. In this study, we examined cannabis use behaviors in large metropolitan, small metropolitan, and nonmetropolitan areas. We focused on interactions between geographic areas and health insurance status and medical cannabis laws (MCL). METHODS: Data came from the 2015-2018 National Survey on Drug Use and Health (NSDUH; N = 171,766 adults; N = 36,175 cannabis users). Weighted chi-squares tests of independence and multivariable Poisson regression models were used to examine study questions. RESULTS: Past-year use was highest in large metropolitan areas (16.08 %). Frequent use was highest among nonmetropolitan area users (48.67 %). Uninsured adults had a higher likelihood of past-year use (RRR = 1.21, 95 % CI = 1.14, 1.29) and frequent use (RRR = 1.27, 95 % CI = 1.14, 1.41), but a lower likelihood of cannabis use disorder (RRR = 0.77, 95 % CI = 0.66, 0.89). Uninsured adults in nonmetropolitan areas had a higher likelihood (RRR = 1.62, 95 % CI = 1.39, 1.88) of past-year use than insured nonmetropolitan area adults. MCL state residency was associated with a higher likelihood of frequent use among nonmetropolitan (RRR = 1.39, 95 % CI = 1.11, 1.74) and small metropolitan users (RRR = 1.30, 95 % CI = 1.15, 1.47). Cannabis use disorder likelihood did not vary by geographic area. CONCLUSIONS: Lack of health insurance and MCL state residency are significant variables affecting cannabis use behaviors in small metropolitan and/or nonmetropolitan areas.

Towards poverty alleviation in developing countries: An empirical study of the impact of land tenure reforms in Kati, Mali.

Post-colonial land tenure reforms in emerging countries have partly aimed at poverty reduction through equitable land access. However, the poverty rate keeps rising in rural and peri-urban settings in Sub-Saharan Africa dominated by agricultural activities. This article reviews land tenure reforms in Mali, from the year 2000 to 2017 regarding poverty alleviation and evaluates their impacts on indigenous smallholder farmers, using multiple linear and logistic regression models and local experts' elicitations. The results indicate that the advent of land titles as the only definitive evidence of land ownership, following the reforms, has generally weakened customary land management. Smallholder farmers face several barriers to obtaining land titles, limiting equity in land access and security. This has paved way for land markets marred by irregularities and resulted in colossal loss of agricultural lands, which are the main source of rural livelihood. Thus, the reforms have not yielded the intended poverty reduction outcomes. The study recommends that land transfers must be authorised by a single institution, represented at the various administrative levels, which issues an authentic and incorruptible document using appropriate technology. Moreover, since pro-poor provisions in the reforms usually lack implementing decrees in Mali, political will is key to achieving equitable land access and security.

Food group intakes and all-cause mortality among a young older Japanese population of the same age: the New Integrated Suburban Seniority Investigation Project.

Evaluating the effects of dietary intake on mortality in older populations has become increasingly important in modern aging societies. The objective of the present study was to investigate the associations between food group intakes and all-cause mortality among a young older population. We conducted a prospective study on 1,324 men and 1,338 women aged 64-65 years at baseline who were living in a suburban city from 1996 to 2005. The participants were followed for all-cause mortality from 1996 through 2015 to assess the effects of 17 food group intakes (g) per 1,000 kcal after multivariable adjustments in proportional hazard models. During follow-up (mean: 13.2 years), 339 deaths were registered. In women, total mortality was significantly and inversely associated with the consumption of milk and dairy products and vegetables. The hazard ratios across intake quartiles after multivariable adjustment were 1, 0.70 (95% confidence interval: 0.42-1.17), 0.66 (0.40-1.10), and 0.40 (0.22-0.75) (P for trend = 0.003) for milk and dairy products, and 1, 0.77 (0.46-1.28), 0.83 (0.50-1.38), and 0.42 (0.23-0.78) (P for trend = 0.008) for vegetables. In men, a positive association was found between total mortality and sugar and sweetener consumption (P for trend = 0.038). Higher consumption of milk and dairy products and vegetables was suggested to reduce all-cause mortality in young older women.

The average age of all participants was 14.9 ±â€Š5.11.TYPE study is the first large-scale school-based multi-ethnic survey in suburban site of Northern China. Continuous identification of retinal microvascular changes with eye diseases will provide new insights into the control related diseases in school-age children and adolescents.

Nonmetropolitan COVID-19 Incidence and Mortality Rates Surpassed Metropolitan Rates Within the First 24 Weeks of the Pandemic Declaration: United States, March 1-October 18, 2020.

PURPOSE: This report compares COVID-19 incidence and mortality rates in the nonmetropolitan areas of the United States with the metropolitan areas across three 11-week periods from March 1 to October 18, 2020. METHODS: County-level COVID-19 case, death, and population counts were downloaded from USAFacts.org. The 2013 NCHS Urban-Rural Classification Scheme was collapsed into two categories called metropolitan (large central, large fringe, medium, and small metropolitans) and nonmetropolitan (micropolitan/noncore). Daily COVID-19 incidence and mortality rates were computed to show temporal trends for each of these two categories. Maps showing the ratio of nonmetropolitan to metropolitan COVID-19 incidence and mortality rates by state identify states with higher rates in nonmetropolitan areas than in metropolitan areas in each of the three 11-week periods. FINDINGS: In the period between March 1 and October 18, 2020, 13.8% of the 8,085,214 confirmed COVID-19 cases and 10.7% of the 217,510 deaths occurred among people residing in nonmetropolitan counties. The nonmetropolitan incidence and mortality trends steadily increased and surpassed those in metropolitan areas, beginning in early August. CONCLUSIONS: Despite the relatively small size of the US population living in nonmetropolitan areas, these areas have an equal need for testing, health care personnel, and mitigation resources. Having state-specific rural data allow the development of prevention messages that are tailored to the sociocultural context of rural locations.

A systematic literature review of schistosomiasis in urban and peri-urban settings.

BACKGROUND: Schistosomiasis is a parasitic disease caused by trematode worms of the genus Schistosoma and belongs to the neglected tropical diseases. The disease has been reported in 78 countries, with around 290.8 million people in need of treatment in 2018. Schistosomiasis is predominantly considered a rural disease with a subsequent focus of research and control activities in rural settings. Over the past decades, occurrence and even expansion of schistosomiasis foci in peri-urban and urban settings have increasingly been observed. Rural-urban migration in low- and middle-income countries and subsequent rapid and unplanned urbanization are thought to explain these observations. Fifty-five percent (55%) of the world population is already estimated to live in urban areas, with a projected increase to 68% by 2050. In light of rapid urbanization and the efforts to control morbidity and ultimately achieve elimination of schistosomiasis, it is important to deepen our understanding of the occurrence, prevalence, and transmission of schistosomiasis in urban and peri-urban settings. A systematic literature review looking at urban and peri-urban schistosomiasis was therefore carried out as a first step to address the research and mapping gap. METHODOLOGY: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic computer-aided literature review was carried out using PubMed, ScienceDirect, and the World Health Organization Database in November 2019, which was updated in March 2020. Only papers for which at least the abstract was available in English were used. Relevant publications were screened, duplicates were removed, guidelines for eligibility were applied, and eligible studies were reviewed. Studies looking at human Schistosoma infections, prevalence, and intensity of infection in urban and peri-urban settings were included as well as those focusing on the intermediate host snails. PRINCIPAL FINDINGS: A total of 248 publications met the inclusion criteria. The selected studies confirm that schistosomiasis is prevalent in peri-urban and urban areas in the countries assessed. Earlier studies report higher prevalence levels in urban settings compared to data extracted from more recent publications, yet the challenge of migration, rapid uncontrolled urbanization, and resulting poor living conditions highlight the potential for continuous or even newly established transmission to take place. CONCLUSIONS: The review indicates that schistosomiasis has long existed in urban and peri-urban areas and remains a public health problem. There is, however, a challenge of comparability of settings due to the lack of a clear definition of what constitutes urban and peri-urban. There is a pressing need for improved monitoring of schistosomiasis in urban communities and consideration of treatment strategies.

Unmet contraceptive needs among female sex workers (FSWs) in semi urban Blantyre, Malawi.

BACKGROUND: Research has paid limited attention to understanding factors that are associated with unmet contraceptive needs among female sex workers. In order to fill this knowledge gap, we estimated the prevalence of unmet contraceptive needs and examined associated factors among FSWs in semi urban Blantyre, Malawi. METHODS: We used systematic sampling to recruit 290 female sex workers in semi urban Blantyre between February and March 2019. In this cross sectional study, we used questionnaire interviews to collect quantitative data. We calculated the mean and standard deviation for continuous variables and proportions for categorical variables to describe the data. Logistic regression analysis was used to investigate the association between unmet needs (the outcome variable) and explanatory variables such as: having a steady partner, fear of contraceptives' side effects and having a history of sexually transmitted infections. RESULTS: Out of the 290 study participants 102 (35.2%) reported unmet contraceptive needs. The following factors were significantly associated with unmet contraceptive needs in multivariate analysis: female sex workers' history of physical and sexual violence by clients [OR 3.38, 95% CI (1.10, 10.43)], p < 0.03, participants with a steady partner [OR 3.28, 95% CI (1.89, 5.68)], p < 0.001, and participants who feared side effects of contraceptives [OR 2.99, 95% CI (1.73, 5.20)], p < 0.001. CONCLUSION: Reproductive Health services should address barriers to contraceptives use for instance: violence by female sex workers' clients, fear and misinformation on contraceptives. There is need to improve awareness of contraceptives. Specific health promotion interventions on female sex workers engaged in a steady partnership are recommended. It is important to enhance the knowledge, attitudes, and counseling skills of health care providers in order to address unmet contraceptive needs among female sex workers in semi-urban Blantyre. Unmet contraceptive needs are defined as lack of contraceptives use in heterosexually active women of childbearing age who do not wish to become pregnant. Unmet contraceptive needs are the main cause of short inter-pregnancy intervals, early childbearing, physical abuse, unintended pregnancy, poor maternal and child health outcomes. Several studies have documented low contraceptives use among female sex workers (FSWs), but research has paid limited attention to understanding factors associated with unmet contraceptive needs among this population in semi urban Blantyre Malawi. In order to fill this knowledge gap, we estimated the prevalence of unmet contraceptive needs and examined factors that were associated with unmet contraceptive needs among FSWs in semi urban Blantyre, Malawi. We recruited 290 FSWs and collected quantitative data. These data were analyzed to obtain descriptive statistics. Logistic regression analysis was used to investigate the association between unmet contraceptive needs (the outcome variable) and explanatory variables such as: FSWs with history of physical and sexual violence by clients, having a steady partner, fear of contraceptives' side effects and having a history of sexually transmitted infections. Out of the 290 FSWs, 35% reported unmet contraceptive needs. The following factors were significantly associated with unmet contraceptive needs in multivariate analysis: FSWs' history of physical and sexual violence by clients, participants with a steady partner and participants who feared contraceptive side effects. Sexual and Reproductive Health services should address barriers to contraceptives use, female sex workers exposure to violence, having a steady partners and concerns about side effects. There is also a need to improve the knowledge, attitudes, and counseling skills of health providers in order to address unmet contraceptive needs among FSWs.
