In a setting of universal health care access, we compared diabetes control between Caucasians and African Americans (AA) living with HIV. This was a cross-sectional analysis of data from a cohort study among military members living with HIV and diabetes. Using adjusted logistic regression models, we compared proportions of Caucasians and AA meeting the following diabetes treatment goals: hemoglobin A1c <7.0%, blood pressure (BP) <140/90 mm Hg, low density lipoprotein cholesterol <100 mg/dL, and not smoking. We included 107 Caucasian (mean age 37 years) and 126 AA (mean age 33 years) participants. A similar proportion of Caucasians and AA were prescribed diabetes (∼60%) and BP (∼80%) medications. Yet, more Caucasians met the BP treatment goal (77% [54%, 90%]) than AA (61% [36%, 82%]). Thus, more Caucasians met the combined A1c, BP, and cholesterol goals for diabetes control (25% [10%, 49%]) than AA (13% [5%, 31%]). Despite having equal access to health care, AA in this study have poorer diabetes control than Caucasians.
Despite common notion that the correlation of socioeconomic status with child cognitive performance may be driven by both environmentally– and genetically–mediated transactional pathways, there is a lack of longitudinal and genetically informed research that examines these postulated associations. The present study addresses whether family income predicts associative memory growth and hippocampal development in middle childhood and tests whether these associations persist when controlling for DNA–based polygenic scores of educational attainment. Participants were 142 6–to–7–year–old children, of which 127 returned when they were 8–to–9 years old. Longitudinal analyses indicated that the association of family income with children's memory performance and hippocampal volume remained stable over this age range and did not predict change. On average, children from economically disadvantaged background showed lower memory performance and had a smaller hippocampal volume. There was no evidence to suggest that differences in memory performance were mediated by differences in hippocampal volume. Further exploratory results suggested that the relationship of income with hippocampal volume and memory in middle childhood is not primarily driven by genetic variance captured by polygenic scores of educational attainment, despite the fact that polygenic scores significantly predicted family income.
Risk factors for adolescent perpetration of or victimization by dating violence stem from different levels of adolescents’ social ecologies, including the family, individual, and peer domains. However, these multiple risk factors have not been fully integrated into a single comprehensive model of dating violence development. The present study examined prospective links between exposure to family violence in pre-adolescence; pro-violent beliefs, aggression, deviant peer affiliation, and aggression toward opposite-sex peers in early adolescence and dating violence in late adolescence. Using a longitudinal study of 461 youth (51 % female; 80 % African American, 19 % Caucasian, 1 % other ethnicities), path modeling evaluated a theoretically developed dual pathway model involving a general violence pathway and an early romantic aggression pathway. Each pathway links exposure to family violence in pre-adolescence with early adolescent pro-violent beliefs and/or aggressive behavior. In both pathways, pro-violent beliefs may reinforce aggressive behaviors between same-sex and opposite-sex peers, as well as strengthen bonds with deviant peers. In the last part of both pathways, aggressive behavior and peer deviance in early adolescence may contribute directly to late adolescent dating violence perpetration and victimization. The findings provided support for both pathways, as well as sex differences in the model.
There is increasing evidence that racism is a cause of poor health outcomes in the United States, including adverse birth outcomes among Blacks. However, research on the health consequences of racism has faced measurement challenges due to the more subtle nature of contemporary racism, which is not necessarily amenable to assessment through traditionally used survey methods. In this study, we circumvent some of these limitations by examining a previously developed Internet query-based proxy of area racism (Stephens-Davidowitz, 2014) in relation to preterm birth and low birthweight among Blacks. Area racism was measured in 196 designated market areas as the proportion of total Google searches conducted between 2004 and 2007 containing the “n-word.” This measure was linked to county-level birth data among Blacks between 2005 and 2008, which were compiled by the National Center for Health Statistics; preterm birth and low birthweight were defined as <37 weeks gestation and <2500 g, respectively. After adjustment for maternal age, Census region, and county-level measures of urbanicity, percent of the Black population, education, and poverty, we found that each standard deviation increase in area racism was associated with relative increases of 5% in the prevalence of preterm birth and 5% in the prevalence of low birthweight among Blacks. Our study provides evidence for the utility of an Internet query-based measure as a proxy for racism at the area-level in epidemiologic studies, and is also suggestive of the role of racism in contributing to poor birth outcomes among Blacks.
Introduction Emerging research has linked women's sanitation and menstrual hygiene experiences with increased vulnerability to violence outside the home. Few studies, however, have investigated the relationship between menstruation and violence perpetrated by family members. This type of violence may be linked specifically to restrictions placed on women during menstruation, which are common in some regions of Nepal owing to shared power differentials that disfavour women, and societal norms that stigmatise menstruation. Objective To record the prevalence of menstrual restrictions experienced by married women and examine potential associations between intimate partner violence (IPV) in the past year and menstrual restrictions imposed by husbands and/or in-laws among women in three districts of Nepal: Nawalparasi, Kapilvastu and Chitwan. Methods Baseline data from a larger randomised control trial aiming to reduce IPV in three districts of the Terai region of Nepal (n=1800) were used to assess the prevalence of menstrual restrictions and the association with IPV. Results Nearlythree out of four women (72.3%) reported experiencing high menstrual restriction, or two or more types of menstrual restriction. When controlling for demographic variables and IPV, no type of IPV was associated with high menstrual restrictions. Conclusion The experience of menstrual restriction was widespread in this sample of women in Nepal. Future research should seek to identify how best to capture menstrual stigma and deviations around such norms. The global health and development community should prioritise integration with existing water and sanitation programmes to reduce stigma and ensure the well-being of menstruating women and girls.

The authors' aims were to assess the associations of sexual risk behavior with psychiatric impairment and individual, peer, and partner attitudes among adolescents receiving mental health treatment. Adolescents (N = 893, 56% female, 67% African American) completed assessments of psychiatric impairment, rejection sensitivity, peer norms, HIV knowledge, perceived vulnerability, self-efficacy, and condom use intentions. Two structural equation models were used to test the study hypotheses: one for sexually active youth and one for nonactive youth. For nonactive youth, psychiatric impairment influenced self-efficacy and condom use intentions via peer norms, rejection sensitivity, and perceived vulnerability. Among the sexually active youth, sexual risk was related to impairment and previous condom use. These results suggest that individual, peer, and partner factors are related to impairment and to sexual risk attitudes but depend on previous sexual experience.
Human behavior has long engaged in collective behavior assembling in crowds. The Christian pilgrimage to the Holy Land has been recorded since the 4th century, while the Hajj, Islam's great pilgrimage, has existed for fourteen centuries, of which a body of literature devoted to the travelogues of the Hajj has been recorded for over ten centuries. Football is a sport played worldwide by more than 1.5 million teams and in 300,000 clubs. Most however play outside of the officially organized sphere: more than 4 percent of the global population plays football, including 270 million amateur players. Assembling for specific events is a uniquely human behavior, though the formal study of crowds did not begin until the mid-Twentieth Century.
Today Mass Gathering Medicine focuses on the public health challenges to hosting events attended by a large enough number of people, at a specific site, for a defined period of time, likely to strain both the planning and response to the mass gathering of a community, state, or nation. All of us can recall attending a mass gathering, whether it be watching one's favorite rock group in performance or assembling for religious pilgrimage. Certainly, the event itself is transporting and transforming and the unison of behaviors and activities can be enormously enriching, uplifting and overwhelming, just as much as they may be at times dangerous and high risk.
This review seeks to draw contrasts and comparisons between sporting gatherings and religious gatherings with a chief focus on Hajj, among the largest of all mass gatherings today. We will find there are some powerful similarities as well as stark differences. Each bequeaths a legacy which can inform the other and, as we make our observations, we join with you and the legions of other investigators who continue to remain fascinated and enthralled by mass gatherings which are among the most beloved and beholden events of modern humanity.
Mass gathering (MG) medicine emerged against the backdrop of the 2009 pandemic H1N1 Public Health Emergency of International Concern (PHEIC) when the Kingdom of Saudi Arabia (KSA) hosted the largest annual mass gathering of over 3 million pilgrims from 180 plus countries. However, the events surrounding the latest threat to global health, the PHEIC COVID-19, may be sufficient to highlight the role of mass gatherings, mass migration, and other forms of dense gatherings of people on the emergence, sustenance, and transmission of novel pathogens. The COVID-19 spread illustrates the role of MGs in exacerbation of the scope of pandemics.
Cancellation or suspension of MGs would be critical to pandemic mitigation. It is unlikely that medical countermeasures are available during the early phase of pandemics. Therefore, mitigation of its impact, rather than containment and control becomes a priority during pandemics. As the most systematically studied MG-related respiratory disease data come from KSA, the cancellation of Umrah by the KSA authorities, prior to emergence of cases, provide the best opportunity to develop mathematical models to quantify event cancellations related mitigation of COVID-19 transmission in KSA and to the home countries of pilgrims. COVID-19 has already provided examples of both clearly planned event cancellations such as the Umrah suspension in KSA, and where outbreaks and events were continued.
Background:
In Ethiopia, neonatal mortality accounts for approximately 54% of under-five deaths with the majority of these deaths driven by infections. Possible Severe Bacterial Infection (PSBI) in neonates is a syndromic diagnosis that non-clinical health care providers use to identify and treat newborns with signs of sepsis. In low- and middle-income countries, referral to a hospital may not be feasible due to transportation, distance or finances. Growing evidence suggests health extension workers (HEWs) can identify and manage PSBI at the community level when referral to a hospital is not possible. However, community-based PSBI care strategies have not been widely scaled-up. This study aims to understand general determinants of household-level care as well as household care seeking and decision-making strategies for neonatal PSBI symptoms.
Methods:
We conducted eleven focus group discussions (FGDs) to explore illness recognition and care seeking intentions from four rural kebeles in Amhara, Ethiopia. FGDs were conducted among mothers, fathers and households with recruitment stratified among households that have had a newborn with at least one symptom of PSBI (Symptomatic Group), and households that have had a newborn regardless of the child's health status (Community Group). Data were thematically analyzed using MAXQDA software.
Results:
Mothers were described as primary caretakers of the newborn and were often appreciated for making decisions for treatment, even when the father was not present. Type of care accessed was often dependent on conceptualization of the illness as simple or complex. When symptoms were not relieved with clinical care, or treatments at facilities were perceived as ineffective, alternative methods were sought. Most participants identified the health center as a reliable facility. While designed to be the first point of access for primary care, health posts were not mentioned as locations where families seek clinical treatment.
Conclusions:
This study describes socio-contextual drivers for PSBI treatment at the community level. Future programming should consider the role community members have in planning interventions to increase demand for neonatal care at primary facilities. Encouragement of health post utilization could further allow for heightened accessibility-acceptability of a simplified PSBI regimen.
On May 21, 2009, WHO's Director-General, Margaret Chan decided that influenza A (H1N1) was not going to become a pandemic. Not because of any epidemiological rationale but because the very term “pandemic” was feared to trigger global panic. “Swine flu” would have become a stage six pandemic on that date. But Chan observed that “I know that you have given me a lot of trust and flexibility, and this is not an easy task. I need to balance how science should play a role and not to forget about the people.” Not “science” but public response was the key to the rethinking of what our present outbreak of H1N1 should be labelled. By June 11, 2009, H1N1 was a designated pandemic. This too had its political dimension with medical consequences.
