Disparities in Demographics in Hip Arthroplasty Between U.S. Active Duty Military and the ACS-NSQIP Clinical Registry.

INTRODUCTION: Patient demographics, such as sex and age, are known risk factors for undergoing revision following primary total hip arthroplasty (THA). The military population is unique because of the increased rates of primary and secondary osteoarthritis of the hip. Treatment options are limited for returning patients to their line of duty; however, THA has been shown to be an effective option. The primary purpose of this study was to evaluate and contrast the demographic differences of patients undergoing primary THA between the U.S. active duty military population and the general population. The secondary goal was to identify the proportion of primary THA performed at the MTF within the military health system (MHS). METHODS: This was an exempt study determined by the local institutional review board. A retrospective analysis of the MHS Data Repository (MDR) and the National Surgical Quality Improvement Program (NSQIP) was performed. The databases were used to identify the patients who underwent THA from January 1, 2015 to December 31, 2020. The MDR was used to identify demographics such as sex, age, setting of surgery, geographic location, previous military deployments, history of deployment-related injuries, branch of service, and rank. The NSQIP database was queried for sex and age. The median age of the population was compared using the Mann-Whitney U test and gender was compared using the Chi-square test. RESULTS: The MDR was used to evaluate 2,734 patients, whereas the NSQIP database was used to evaluate 223,832 patients. In the military population, patients who underwent THA were 87.7% male with an average age of 45 years, whereas in the general population as measured via the NSQIP database, 45.2% patients were male with an average age of 66.0 years. Comparing the two groups, we demonstrated that the military patients were significantly more likely to be younger (P < .001) and males (P < .001). Only 29.6% of primary THAs were performed within the MTF. CONCLUSIONS: Patients in the MHS are undergoing THA at a younger age and are more likely to be male compared to the general population. A significant portion of primary THAs in the MHS are also being performed at civilian institutions. These demographics may result in increased risk of revision; however, long-term studies are warranted to evaluate survivorship in this unique population.

Consumer food environment assessment and its association with socioeconomic factors in a midsize city in Brazil / Avaliação do ambiente alimentar do consumidor e suas associações com fatores socioeconômicos em uma cidade brasileira de médio porte

ABSTRACT Objective To assess the consumer food environment and its associations with socioeconomic factors in a midsize Brazilian city. Methods An ecological study that assessed the consumer food environment through audits in a stratified and proportional sample of food stores. The ESAO-S and the ESAO-R instruments were used. Access to healthy food was assessed using the Healthy Food Store Index and the Healthy Meal Restaurant Index. Socioeconomic and demographic characteristics and the Health Vulnerability Index were obtained from the 2010 Demographic Census. Statistical analyses were performed using the IBM®SPSSNo-Break®No-Break software. Result A total of 280 food stores were assessed. Only 47.1% of food stores for home consumption had fruits, vegetables, or legumes. High availability of ultra-processed food was identified, such as sugar-sweetened beverages (85.0%) and chocolate sandwich cookies (77.8%). The prices of some unprocessed foods and the availability of snacks were different according to socioeconomic characteristics. In food stores for immediate consumption, low availability of healthy options was identified, and, in most of them, natural juices had higher prices than sugar-sweetened beverages (87.1%). The mean Healthy Food Store Index score was 5.1 (SD=3.6), and the Healthy Meal Restaurant Index was 2.4 (SD=1.2). Conclusion These findings allow us to expand the knowledge about the consumer food environment, helping to implement public policies related to food supply.

RESUMO Objetivo Avaliar o ambiente alimentar do consumidor e suas associações com fatores socioeconômicos em uma cidade brasileira de médio porte. Métodos Estudo ecológico, no qual avaliou-se o ambiente alimentar do consumidor por meio de auditorias em uma amostra estratificada e proporcional de estabelecimentos que comercializam alimentos. Utilizaram-se os instrumentos ESAO-S e ESAO-R. O acesso a alimentos saudáveis foi avaliado por meio do Healthy Food Store Index e do Healthy Meal Restaurant Index. As características socioeconômicas, demográficas e o índice de vulnerabilidade da saúde foram obtidos a partir do Censo Demográfico de 2010. As análises estatísticas foram realizadas no software IBMNo-Break®No-BreakSPSSNo-Break®No-Break. Resultados Avaliaram-se 280 estabelecimentos, onde apenas 47,1% dos comércios de alimentos para consumo em domicílio possuíam frutas, verduras ou legumes. Foi identificada uma elevada disponibilidade de alimentos ultraprocessados, como refrigerantes (85,0%) e biscoitos (77,8%). Os preços de alguns alimentos in natura e a disponibilidade de salgadinhos foram diferentes segundo as características socioeconômicas. Nos comércios de alimentos para consumo imediato, foi identificada baixa disponibilidade de opções saudáveis e, na maioria deles, os sucos naturais apresentaram preços superiores a refrigerantes (87,1%). A pontuação média do Healthy Food Store Index foi 5,1 (DP=3,6) e do Healthy Meal Restaurant Index de 2,4 (DP=1,2). Conclusão Os resultados permitem ampliar o conhecimento sobre o ambiente alimentar do consumidor, auxiliando na implantação de políticas públicas relacionadas ao abastecimento alimentar.

Adverse Childhood Experiences and Subsequent Chronic Diseases Among Middle-aged or Older Adults in China and Associations With Demographic and Socioeconomic Characteristics.

Importance: Associations between adverse childhood experiences (ACEs) and chronic diseases among middle-aged or older Chinese individuals have not been well documented. In addition, whether demographic and socioeconomic characteristics modify any such associations has been underexplored. Objectives: To examine associations between ACEs and subsequent chronic diseases and to assess whether age, sex, educational level, annual per capita household expenditure level, and childhood economic hardship modify these associations. Design, Setting, and Participants: This population-based cross-sectional study used data from the China Health and Retirement Longitudinal Study (CHARLS), a survey of residents aged 45 years or older in 28 provinces across China; specifically, the study used data from the CHARLS life history survey conducted from June 1 to December 31, 2014, and a CHARLS follow-up health survey conducted from July 1 to September 30, 2015. The study population included 11 972 respondents aged 45 years or older who had data on at least 1 of 14 specified chronic diseases and information on all 12 of the ACE indicators included in this study. Data analysis was performed from December 1 to 30, 2020. Exposures: Any of 12 ACEs (physical abuse, emotional neglect, household substance abuse, household mental illness, domestic violence, incarcerated household member, parental separation or divorce, unsafe neighborhood, bullying, parental death, sibling death, and parental disability), measured by indicators on a questionnaire. The number of ACEs per participant was summed and categorized into 1 of 5 cumulative-score groups: 0, 1, 2, 3, and 4 or more. Main Outcomes and Measures: Hypertension, dyslipidemia, diabetes, heart disease, stroke, chronic lung disease, asthma, liver disease, cancer, digestive disease, kidney disease, arthritis, psychiatric disease, and memory-related disease were defined by self-reported physician diagnoses or in combination with health assessment and medication data. Multimorbidity was defined as the presence of 2 or more of these 14 chronic diseases. Logistic regression models were used to assess associations of the 12 ACEs with the 14 chronic diseases and with multimorbidity. Modification of the associations by demographic and socioeconomic characteristics was assessed by stratified analyses and tests for interaction. Results: Of the 11 972 individuals included (mean [SD] age, 59.85 [9.56] years; 6181 [51.6%] were females), 80.9% had been exposed to at least 1 ACE and 18.0% reported exposure to 4 or more ACEs. Compared with those without ACE exposure, participants who experienced 4 or more ACEs had increased risks of dyslipidemia, chronic lung disease, asthma, liver disease, digestive disease, kidney disease, arthritis, psychiatric disease, memory-related disease, and multimorbidity. The estimated odds ratios (ORs) ranged from 1.27 (95% CI, 1.02-1.59) for dyslipidemia to 2.59 (95% CI, 2.16-3.11) for digestive disease. A dose-response association was also observed between the number of ACEs and the risk of most of the chronic diseases (excluding hypertension, diabetes, and cancer) (eg, chronic lung disease for ≥4 ACEs vs none: OR, 2.01; 95% CI, 1.59-2.55; P < .001 for trend) and of multimorbidity (for individuals among the overall study population with ≥4 ACEs vs none: OR, 2.03; 95% CI, 1.70-2.41; P < .001 for trend). The demographic or socioeconomic characteristics of age, sex, educational level, annual per capita household expenditure level, or childhood economic hardship were not shown to significantly modify the associations between ACEs and multimorbidity. Conclusions and Relevance: In this population-based, cross-sectional study of adults in China, exposure to ACEs was associated with higher risks of chronic diseases regardless of demographic and socioeconomic characteristics during childhood or adulthood. These findings suggest a need to prevent ACEs and a need for a universal life-course public health strategy to reduce potential adverse health outcomes later in life among individuals who experience them.

The Impact of Purifying and Background Selection on the Inference of Population History: Problems and Prospects.

Current procedures for inferring population history generally assume complete neutrality-that is, they neglect both direct selection and the effects of selection on linked sites. We here examine how the presence of direct purifying selection and background selection may bias demographic inference by evaluating two commonly-used methods (MSMC and fastsimcoal2), specifically studying how the underlying shape of the distribution of fitness effects and the fraction of directly selected sites interact with demographic parameter estimation. The results show that, even after masking functional genomic regions, background selection may cause the mis-inference of population growth under models of both constant population size and decline. This effect is amplified as the strength of purifying selection and the density of directly selected sites increases, as indicated by the distortion of the site frequency spectrum and levels of nucleotide diversity at linked neutral sites. We also show how simulated changes in background selection effects caused by population size changes can be predicted analytically. We propose a potential method for correcting for the mis-inference of population growth caused by selection. By treating the distribution of fitness effect as a nuisance parameter and averaging across all potential realizations, we demonstrate that even directly selected sites can be used to infer demographic histories with reasonable accuracy.

Demographic and socio-economic factors, and healthcare resource indicators associated with the rapid spread of COVID-19 in Northern Italy: An ecological study.

BACKGROUND: COVID-19 rapidly escalated into a pandemic, threatening 213 countries, areas, and territories the world over. We aimed to identify potential province-level socioeconomic determinants of the virus's dissemination, and explain between-province differences in the speed of its spread, based on data from 36 provinces of Northern Italy. METHODS: This is an ecological study. We included all confirmed cases of SARS-CoV-2 reported between February 24th and March 30th, 2020. For each province, we calculated the trend of contagion as the relative increase in the number of individuals infected between two time endpoints, assuming an exponential growth. Pearson's test was used to correlate the trend of contagion with a set of healthcare-associated, economic, and demographic parameters by province. The virus's spread was input as a dependent variable in a stepwise OLS regression model to test the association between rate of spread and province-level indicators. RESULTS: Multivariate analysis showed that the spread of COVID-19 was correlated negatively with aging index (p-value = 0.003), and positively with public transportation per capita (p-value = 0.012), the % of private long-term care hospital beds and, to a lesser extent (p-value = 0.070), the % of private acute care hospital beds (p-value = 0.006). CONCLUSION: Demographic and socioeconomic factors, and healthcare organization variables were found associated with a significant difference in the rate of COVID-19 spread in 36 provinces of Northern Italy. An aging population seemed to naturally contain social contacts. The availability of healthcare resources and their coordination could play an important part in spreading infection.

Diversity and inclusion for the All of Us research program: A scoping review.

The All of Us Research Program (All of Us) is a national effort to accelerate health research by exploring the relationship between lifestyle, environment, and genetics. It is set to become one of the largest research efforts in U.S. history, aiming to build a national resource of data from at least one million participants. All of Us aims to address the need for more diversity in research and set the stage for that diversity to be leveraged in precision medicine research to come. This paper describes how the program assessed demographic characteristics of participants who have enrolled in other U.S. biomedical research cohorts to better understand which groups are traditionally represented or underrepresented in biomedical research. We 1) reviewed the enrollment characteristics of national cohort studies like All of Us, and 2) surveyed the literature, focusing on key diversity categories essential to the program's enrollment aims. Based on these efforts, All of Us emphasizes enrollment of racial and ethnic minorities, and has formally designated the following additional groups as historically underrepresented: individuals-with inadequate access to medical care; under the age of 18 or over 65; with an annual household income at or below 200% of the federal poverty level; who have a cognitive or physical disability; have less than a high school education or equivalent; are intersex; identify as a sexual or gender minority; or live in rural or non-metropolitan areas. Research accounting for wider demographic variability is critical. Only by ensuring diversity and by addressing the very barriers that limit it, can we position All of Us to better understand and tackle health disparities.

Spatial heterogeneity and socioeconomic determinants of opioid prescribing in England between 2015 and 2018.

BACKGROUND: Opioid overdoses have had a serious impact on the public health systems and socioeconomic welfare of several countries. Within this broader context, we focus our study on primary care opioid prescribing in England from 2015 to 2018, particularly the patterns of spatial variations at the community level and the socioeconomic and environmental factors that drive consumption. METHODS: Leveraging open data sources, we combine prescription records with aggregated data on patient provenance and build highly granular maps of Oral Morphine Equivalent (OME) prescribing rates for Lower Layer Super Output Areas (LSOA). We quantify the strength of spatial associations by means of the Empirical Bayes Index (EBI) that accounts for geographical variations in population density. We explore the interplay between socioeconomic and environmental determinants and prescribing rates by implementing a multivariate logistic regression model across different temporal snapshots and spatial scales. RESULTS: We observe, across time and geographical resolutions, a significant spatial association with the presence of localized hot and cold spots that group neighboring areas with homogeneous prescribing rates (e.g., EBI = 0.727 at LSOA level for 2018). Accounting for spatial dependency effects, we find that LSOA with both higher employment deprivation (OR = 62.6, CI 52.8-74.3) and a higher percentage of ethnically white (OR = 30.1, CI 25.4-35.7) inhabitants correspond to higher prescribing rates. Looking at educational attainment, we find LSOA with the prevalent degree of education being apprenticeship (OR = 2.33, CI 1.96-2.76) a risk factor and those with level 4+ (OR = 0.41, CI 0.35-0.48) a protective factor. Focusing on environmental determinants, housing (OR = 0.18, CI 0.15-0.21) and outdoor environment deprivation (OR = 0.62, CI 0.53-0.72) indices capture the bi-modal behavior observed in the literature concerning rural/urban areas. The results are consistent across time and spatial aggregations. CONCLUSIONS: Failing to account for local variations in opioid prescribing rates smooths out spatial dependency effects that result in underestimating/overestimating the impact on public health policies at the community level. Our study suggests a novel approach to inform more targeted interventions toward the most vulnerable population strata.

Social, psychological, and demographic characteristics of dehumanization toward immigrants.

This study extends the current body of work on dehumanization by evaluating the social, psychological, and demographic correlates of blatant disregard for immigrants. Participants (n = 468) were randomly assigned to read a scenario where 1) an immigrant or 2) an immigrant and their child were caught illegally crossing the southern border of the United States, and then rated how long they should spend in jail if convicted. Participants reported that they would sentence the immigrant to more jail time than the immigrant and child. Those who sent immigrants to jail for more time also viewed them as socially distant and less human, described immigration in impersonal terms, and endorsed other social harms unrelated to immigration (e.g., the death penalty for convicted murderers). Crucially, endorsed social harms accounted for explained variance beyond simply holding conservative views. We position these data within the current literature on dehumanization theory and immigration issues.

Psychosocial and Sociodemographic Contributors to Breastfeeding Intention in First-Time Mothers.

OBJECTIVE: Breastfeeding has multiple benefits for women and babies. Understanding factors contributing to intention to exclusively breastfeed may allow for improving the rates in first-time mothers. The study objective was to examine factors associated with a woman's intention to breastfeed her first child. METHODS: A secondary analysis of the prospective "Nulliparous Pregnancy Outcomes Study: monitoring mothers-to-be" (nuMoM2b) study of nulliparous women in the U.S. with singleton pregnancies was performed. Sociodemographic and psychosocial factors were analyzed for associations with breastfeeding intention. RESULTS: For the 6443 women with complete information about breastfeeding intention and all factors under consideration, women who intended to breastfeed (either exclusively or any breastfeeding) were more likely to be older, not black, have reached a higher level of education, have higher incomes, have a lower body mass index (BMI), and be nonsmokers. Reporting a planned pregnancy and several psychosocial measures were also associated with intention to breastfeed. In the multivariable analysis for exclusive breastfeeding, in addition to age, BMI, race, income, education, and smoking, of the psychosocial measures assessed, only women with higher hassle intensity ratios on the Pregnancy Experience Scale had lower odds of exclusive breastfeeding intention (OR 0.71, 95% CI 0.55-0.92). Other psychosocial measures were not associated with either exclusive breastfeeding or any breastfeeding after controlling for demographic characteristics. CONCLUSIONS FOR PRACTICE: Several sociodemographic factors, having a planned pregnancy, and fewer intense pregnancy hassles compared to uplifts are associated with intention to exclusively breastfeed. Identifying these factors may allow providers to identify women for focused, multilevel efforts to enhance breastfeeding rates.

Spatial variations and socioeconomic determinants of modern contraceptive use in Ghana: A Bayesian multilevel analysis.

The literature on spatial patterns and contextual factors affecting modern contraceptive use is not well-documented in Ghana. This study describes the spatial variations and estimates the socioeconomic determinants of modern contraception among women in reproductive age in Ghana. Using data from the 2014 Ghana Demographic and Health Survey, both global and local Moran's I test were performed to show spatial autocorrelation and Bayesian multilevel models estimated to determine socioeconomic factors affecting modern contraceptive use. The results show evidence of low prevalence and spatial clustering of modern contraception use across the country. There were also notable regional disparities in contraceptive use that favour mostly the southern regions. Modern contraceptive use is significantly associated with socioeconomic factors such as educational attainment, work status, and marital status, as well as age, religious affiliation, and parity. Contextual factors such as the convenient location of health facility and family planning messages exposure also have a considerable positive effect on modern contraceptive use. Uneducated, unemployed and never-married women are considerably disadvantaged in the utilisation of modern contraception in Ghana. Socioeconomic and contextual factors play a key role in modern contraceptive use in Ghana.

Factors Associated With Childhood Vaccination Adherence in Kindergartens of the Houston Independent School District.

OBJECTIVE: Adequate childhood vaccination rates are crucial for successful control of infectious diseases. Nevertheless, exemption requests, lack of health care access and information and other barriers can reduce vaccination adherence rates, and increase the risk of epidemics. This study aimed to identify factors associated with kindergarten vaccination adherence in the Houston Independent School District (HISD). DESIGN AND SETTING: This study was a retrospective observational data analysis. The study used data from 155 elementary schools of the HISD. The data sets included were (1) Elementary School Profile Reports (2015-2016) and (2) Annual Report of Immunization Status (2016-2017). Logistic regression was used to examine the association between vaccination adherence in schools and the school's student demographic and economic profile, student behavior indicators, teacher profile, and school rank. MAIN OUTCOME MEASURE: A binary variable measuring adequate vaccination adherence rates in schools is the main outcome variable. RESULTS: Lower vaccination adherence among the kindergarten students was associated with higher enrollment, a higher percentage of African American students and students with English as second language, and a lower percentage of gifted/talented students in the schools. CONCLUSIONS: The school characteristics that were found to be significantly associated with kindergarten student vaccination adherence in this study are the ones that have historically been associated with socioeconomic determinants of health and socioeconomic privilege. Hence, the findings of this study suggest the need for development of policies and interventions that can help overcome the barriers associated with low socioeconomic status, language, and marginalization in order to improve vaccination rates in school districts. These include culturally appropriate polices and health promotion, patient navigation, and educational interventions that can overcome the challenges faced by socially and economically vulnerable minorities and immigrant communities in order to improve vaccination rates.

Monitoring inequality changes in full immunization coverage in infants in Latin America and the Caribbean / Seguimiento de los cambios en las desigualdades con respecto a la cobertura de la inmunización completa en lactantes en América Latina y el Caribe / Monitoramento do avanço das desigualdades na cobertura vacinal completa em lactentes na América Latina e no Caribe

ABSTRACT Objective. To compare inequalities in full infant vaccination coverage at two different time points between 1992 and 2016 in Latin American and Caribbean countries. Methods. Analysis is based on recent available data from Demographic and Health Surveys, Multiple Indicator Cluster Surveys, and Reproductive Health Surveys conducted in 18 countries between 1992 and 2016. Full immunization data from children 12-23 months of age were disaggregated by wealth quintile. Absolute and relative inequalities between the richest and the poorest quintile were measured. Differences were measured for 14 countries with data available for two time points. Significance was determined using 95% confidence intervals. Results. The overall median full immunization coverage was 69.9%. Approximately one-third of the countries have a high-income inequality gap, with a median difference of 5.6 percentage points in 8 of 18 countries. Bolivia, Colombia, El Salvador, and Peru have achieved the greatest progress in improving coverage among the poorest quintiles of their population in recent years. Conclusion. Full immunization coverage in the countries in the study shows higher-income inequality gaps that are not seen by observing national coverage only, but these differences appear to be reduced over time. Actions monitoring immunization coverage based on income inequalities should be considered for inclusion in the assessment of public health policies to appropriately reduce the gaps in immunization for infants in the lowest-income quintile.(AU)

RESUMEN Objetivo. Comparar las desigualdades en cuanto a la cobertura de la inmunización completa en los lactantes en países de América Latina y el Caribe. en dos puntos diferentes en el tiempo: 1992 y el 2016. Métodos. El análisis se basa en datos obtenidos recientemente a partir de las encuestas demográficas y de salud, las encuestas de grupos de indicadores múltiples y las encuestas de salud reproductiva realizadas en 18 países entre 1992 y el 2016. Los datos de la cobertura de la inmunización completa en lactantes (de 12 a 23 meses de edad) fueron desglosados por quintil de riqueza. Se midieron las desigualdades absolutas y relativas entre el quintil de ingresos más altos y el quintil de ingresos más bajos. Se midieron las diferencias en 14 países a partir de los datos disponibles para dos puntos en el tiempo. Se determinó la significación mediante intervalos de confianza del 95%. Resultados. La mediana general de los niveles de cobertura de inmunización total fue de 69,9%. Aproximadamente un tercio de los países presentan una brecha de desigualdad con respecto al quintil de ingresos más altos, con una diferencia entre medianas de 5,6 puntos porcentuales en 8 de 18 países. En los últimos años, Bolivia, Colombia, Perú y El Salvador han logrado el mayor avance en cuanto a la mejora de la cobertura en términos de la población correspondiente al quintil de ingresos más bajos. Conclusiones. En este estudio, la cobertura de inmunización completa en los países muestra brechas de desigualdad con respecto al quintil de ingresos más altos que no se evidencian con tan solo observar el nivel de cobertura a nivel nacional. Sin embargo, estas desigualdades parecen disminuir con el transcurso del tiempo. Debería considerarse la posibilidad de que las medidas de seguimiento de la cobertura de inmunización con base en las desigualdades de los ingresos sean incluidas en la evaluación de las políticas de salud pública. Esto permitiría reducir de manera apropiada las brechas en cuanto a la inmunización en los lactantes en el quintil de ingresos más bajos.(AU)

RESUMO Objetivo. Comparar as desigualdades na cobertura vacinal completa infantil em dois momentos distintos entre 1992 e 2016 em países da América Latina e Caribe. Métodos. A análise se baseou em dados recentes provenientes de Pesquisas Nacionais de Demografia e Saúde, Inquéritos por Conglomerados de Múltiplos Indicadores e Pesquisas de Saúde Reprodutiva realizados em 18 países entre 1992 e 2016. Os dados de cobertura vacinal completa em crianças entre 12 e 23 meses de idade foram desagregados por quintis de renda. Foi mensurada a desigualdade absoluta e relativa entre os quintis de maior e menor renda. A magnitude destas diferenças foi avaliada em 14 países com dados disponíveis nos dois momentos considerados. O nível de significância foi determinado com o uso de intervalos de confiança de 95%. Resultados. A mediana global de cobertura vacinal completa foi de 69,9%. Cerca de um terço dos países apresenta alto nível de desigualdade de renda, com uma diferença mediana de 5,6 pontos percentuais em 8 dos 18 países. Bolívia, Colômbia, El Salvador e Peru obtiveram maior avanço nos últimos anos com o aumento do nível de cobertura na população nos quintis de menor renda destes países. Conclusões. A análise da cobertura vacinal completa infantil nos países estudados indica altos níveis de desigualdade de renda que não são evidentes quando se observa somente a cobertura nacional. No entanto, estas diferenças parecem que vêm diminuindo. Deve-se considerar incluir ações de monitoramento da cobertura vacinal com base nas desigualdades de renda ao se avaliar as políticas de saúde pública a fim de reduzir apropriadamente a disparidade na cobertura vacinal de lactentes pertencentes ao quintil de menor renda.(AU)

Consensus and uncertainty in the geographic range of Aedes aegypti and Aedes albopictus in the contiguous United States: Multi-model assessment and synthesis.

Aedes (Stegomyia) aegypti (L.) and Ae. (Stegomyia) albopictus (Skuse) mosquitoes can transmit dengue, chikungunya, yellow fever, and Zika viruses. Limited surveillance has led to uncertainty regarding the geographic ranges of these vectors globally, and particularly in regions at the present-day margins of habitat suitability such as the contiguous United States. Empirical habitat suitability models based on environmental conditions can augment surveillance gaps to describe the estimated potential species ranges, but model accuracy is unclear. We identified previously published regional and global habitat suitability models for Ae. aegypti (n = 6) and Ae. albopictus (n = 8) for which adequate information was available to reproduce the models for the contiguous U.S. Using a training subset of recently updated county-level surveillance records of Ae. aegypti and Ae. albopictus and records of counties conducting surveillance, we constructed accuracy-weighted, probabilistic ensemble models from these base models. To assess accuracy and uncertainty we compared individual and ensemble model predictions of species presence or absence to both training and testing data. The ensemble models were among the most accurate and also provided calibrated probabilities of presence for each species. The quantitative probabilistic framework enabled identification of areas with high uncertainty and model bias across the U.S. where improved models or additional data could be most beneficial. The results may be of immediate utility for counties considering surveillance and control programs for Ae. aegypti and Ae. albopictus. Moreover, the assessment framework can drive future efforts to provide validated quantitative estimates to support these programs at local, national, and international scales.

Sociodemographic and health situation of teenage students according to sex.

OBJECTIVE: To verify the association between sex (male and female) and sociodemographic, reproductive and sexual variables in teenagers and identify the highest rates of social and health issues among them. METHOD: This was a cross-sectional study conducted with 239 adolescents enrolled in a public school of Salvador, Bahia, Brazil, whose data were produced by applying a structured form processed in Stata. RESULTS: The research indicated an association between females and higher education level (p = 0.02), living with both parents (p = 0.02) and a higher rate of mental, social and behavioral issues. Being a man was associated with sexual initiation (p = 0.00), which occurred before they turned 14 years old (p = 0.05). CONCLUSION: The study variables behave, depending on sex, with smaller or greater chances of experiencing harmful situations, this understanding being essential for subsidizing educational activities that promote the quality of life of teenagers.

Are older adults' demographic characteristics social determinants of their perceived importance, desire, and ability to perform end-of-life self-care actions?

BACKGROUND: Demographic characteristics play a role in influencing the decision to make end-of-life (EOL) directives among older adults living in the United States. AIMS: To examine the associations between older adults' demographic characteristics (age, sex, marital status, residential site, and educational level) and their perceived importance of four self-care actions for EOL planning, as well as their desire and ability to perform these actions. SETTINGS: A cross-sectional survey study of community-dwelling adults living in the southern United States from 2015 to 2016. PARTICIPANTS: Community-dwelling adults aged 65 years and older (N = 123). METHODS: A self-administered tool, the Patient Action Inventory for Self-Care and a demographic questionnaire were used. Multiple logistic regression was performed. RESULTS: Forty-seven of (38.2%) participants lived in an urban community and 76 (61.8%) in a rural community. Demographic variables that were significant across the predictive models were older adults' residence, education levels, age, and marital status. Four demographic characteristics of living in rural areas, without a high school education, being 75 years or older, and married could be social determinants of EOL planning. CONCLUSIONS: Older adults may need community-based support to address their end-of-life needs, especially those elders who want to remain independent in their home environment.

Spatial modeling of leprosy in the state of Bahia and its social determinants: a study of health inequities.

BACKGROUND: Leprosy is a neglected disease caused by Mycobacterium leprae. Brazil has the second largest number of cases in the world. OBJECTIVES: To analyze the spatial distribution of leprosy in the state of BAHIA, Brazil, and the association between his occurrence and the synthetic indicators of municipal socioeconomic performance, social vulnerability and income inequality. METHODS: An ecological study with secondary data obtained from the National System of Notifiable Diseases. Dependent variables: coefficient of detection in the general population and in the population under 15 years old and the rate of grade II of physical disability. Independent variables: Synthetic indicators of socioeconomic performance, social vulnerability and income inequality. RESULTS: The highest coefficients of detection of new cases in the general population and in children under 15 years old are concentrated in the north-west axis and in the southern region of the state. On the other hand, the highest rates of degree II of physical incapacity are concentrated in the north, northeast and south regions. Only the Index of Social and Economic Performance(IPESE)-Economy and Finance composed the final regression model of the general detection coefficients and in children under 15 years old. The municipalities with the highest indexes had the highest detection coefficients, reflecting the capacity to diagnose new cases. STUDY LIMITATIONS: The use of synthetic indicators is a limitation of the study. CONCLUSIONS: Leprosy presents a heterogeneous spatial pattern in the state of BAHIA, and the IPESE-Economics and Finance indicator is the only one with explanatory potential of the disease.

The intention to make preconception lifestyle changes in men: Associated socio-demographic and psychosocial factors.

OBJECTIVE: To determine which socio-demographic and psychosocial factors are associated with the intention for preconception healthily behavioral changes in the general population of reproductive-aged men. DESIGN: A cross-sectional, multicenter study. SETTING: Four secondary schools, 4 Public Centers for Social Welfare, 7 Community Health Centers, and online. All data was collected in the X. PARTICIPANTS: A convenience sample of 304 reproductive-aged men were recruited between July 2015 and July 2016. MEASUREMENTS AND FINDINGS: An existing questionnaire was adapted and validated to assess the intention, self-efficacy, attitude, social influence, knowledge, and barriers towards 10 preconception health behaviors. Simple and multiple logistic and linear regression analyses were performed. The overall intention to make preconception lifestyle changes was high (median score: 0.7 on the 0-1 scale). The multiple linear regression revealed that self-efficacy (p < 0.001), social influence of the close social environment (p = 0.02), and attitude (p = 0.05) were associated with a higher intention score. Experiencing negative emotions and beliefs about pre-pregnancy preparations was associated with less intention for preconception health behaviors (p = 0.001). None of the socio-demographic factors was significantly associated with the intention score. KEY CONCLUSIONS: The overall intention to make preconception lifestyle changes was high, and associated with different psychosocial factors including self-efficacy, social influence, and attitude. IMPLICATIONS FOR PRACTICE: Preconception interventions should target the identified factors to improve preconception health behaviors in men and negative emotions and beliefs about preconception. Interventions about preconception health care should primarily suggest that men bear the same responsibility as women, which will address the current gender politics and could have -in second instance- a positive outcome on pregnancy outcomes. Because socio-demographic characteristics were of no influence, a general approach should be used.
