RESUMO

BACKGROUND: The COVID-19 pandemic priorities have focused on prevention, detection, and response. Beyond morbidity and mortality, pandemics carry secondary impacts, such as children orphaned or bereft of their caregivers. Such children often face adverse consequences, including poverty, abuse, and institutionalisation. We provide estimates for the magnitude of this problem resulting from COVID-19 and describe the need for resource allocation. METHODS: We used mortality and fertility data to model minimum estimates and rates of COVID-19-associated deaths of primary or secondary caregivers for children younger than 18 years in 21 countries. We considered parents and custodial grandparents as primary caregivers, and co-residing grandparents or older kin (aged 60-84 years) as secondary caregivers. To avoid overcounting, we adjusted for possible clustering of deaths using an estimated secondary attack rate and age-specific infection-fatality ratios for SARS-CoV-2. We used these estimates to model global extrapolations for the number of children who have experienced COVID-19-associated deaths of primary and secondary caregivers. FINDINGS: Globally, from March 1, 2020, to April 30, 2021, we estimate 1 134 000 children (95% credible interval 884 000-1 185 000) experienced the death of primary caregivers, including at least one parent or custodial grandparent. 1 562 000 children (1 299 000-1 683 000) experienced the death of at least one primary or secondary caregiver. Countries in our study set with primary caregiver death rates of at least one per 1000 children included Peru (10·2 per 1000 children), South Africa (5·1), Mexico (3·5), Brazil (2·4), Colombia (2·3), Iran (1·7), the USA (1·5), Argentina (1·1), and Russia (1·0). Numbers of children orphaned exceeded numbers of deaths among those aged 15-50 years. Between two and five times more children had deceased fathers than deceased mothers. INTERPRETATION: Orphanhood and caregiver deaths are a hidden pandemic resulting from COVID-19-associated deaths. Accelerating equitable vaccine delivery is key to prevention. Psychosocial and economic support can help families to nurture children bereft of caregivers and help to ensure that institutionalisation is avoided. These data show the need for an additional pillar of our response: prevent, detect, respond, and care for children.

RESUMO

This study, a secondary analysis of the HPTN 068 randomized control trial, aimed to quantify the association of father and male presence with HIV incidence and first pregnancy among 2533 school-going adolescent girls and young women (AGYW) in rural South Africa participating in the trial between March 2011 and April 2017. Participants' ages ranged from 13-20 years at study enrollment and 17-25 at the post-intervention visit. HIV and pregnancy incidence rates were calculated for each level of the exposure variables using Poisson regression, adjusted for age using restricted quadratic spline variables, and, in the case of pregnancy, also adjusted for whether the household received a social grant. Our study found that AGYW whose fathers were deceased and adult males were absent from the household were most at risk for incidence of first pregnancy and HIV (pregnancy: aIRR = 1.30, Wald 95% CI 1.05, 1.61, Wald chi-square p = 0.016; HIV: aIRR = 1.27, Wald 95% CI 0.84, 1.91, Wald chi-square p = 0.263) as compared to AGYW whose biological fathers resided with them. For AGYW whose fathers were deceased, having other adult males present as household members seemed to attenuate the incidence (pregnancy: aIRR = 0.92, Wald 95% CI 0.74, 1.15, Wald chi-square p = 0.462; HIV: aIRR = 0.90, Wald 95% CI 0.58, 1.39, Wald chi-square p = 0.623) such that it was similar, and therefore not statistically significantly different, to AGYW whose fathers were present in the household.

RESUMO

OBJECTIVES: To estimate the proportion of opioid misuse attributable to adverse childhood experiences (ACEs) among adolescents. STUDY DESIGN: A cross-sectional survey was administered to 10 546 seventh-to twelfth-grade students in northeastern Ohio in Spring 2018. Study measures included self-reported lifetime exposure to 10 ACEs and past 30-day use of nonmedical prescription opioid or heroin. Using generalized estimating equations, we evaluated associations between recent opioid misuse, individual ACEs, and cumulative number of ACEs. We calculated population attributable fractions to determine the proportion of adolescents' recent opioid misuse attributable to ACEs. RESULTS: Nearly 1 in 50 adolescents reported opioid misuse within 30 days (1.9%); approximately 60% of youth experienced ≥1 ACE; 10.2% experienced ≥5 ACEs. Cumulative ACE exposure demonstrated a significant graded relationship with opioid misuse. Compared with youth with zero ACEs, youth with 1 ACE (aOR 1.9, 95% CI, 0.9-3.9), 2 ACEs (aOR, 3.8; 95% CI, 1.9-7.9), 3 ACEs (aOR, 3.7; 95% CI, 2.2-6.5), 4 ACEs (aOR, 5.8; 95% CI, 3.1-11.2), and ≥5 ACEs (aOR, 15.3; 95% CI, 8.8-26.6) had higher odds of recent opioid misuse. The population attributable fraction of recent opioid misuse associated with experiencing ≥1 ACE was 71.6% (95% CI, 59.8-83.5). CONCLUSIONS: There was a significant graded relationship between number of ACEs and recent opioid misuse among adolescents. More than 70% of recent adolescent opioid misuse in our study population was attributable to ACEs. Efforts to decrease opioid misuse could include programmatic, policy, and clinical practice interventions to prevent and mitigate the negative effects of ACEs.

RESUMO

OBJECTIVE: To describe associations between childhood violence and forced sexual initiation in young Malawian females. STUDY DESIGN: We analyzed data from 595 women and girls who were 13-24 years old who ever had sex and participated in Malawi's 2013 Violence Against Children Survey, a nationally representative household survey. We estimated the overall prevalence of forced sexual initiation and identified subgroups with highest prevalences. Using logistic regression, we examined childhood violence and other independent predictors of forced sexual initiation. RESULTS: The overall prevalence of forced sexual initiation was 38.9% among Malawian girls and young women who ever had sex. More than one-half of those aged 13-17 years at time of survey (52.0%), unmarried (64.6%), or experiencing emotional violence in childhood (56.9%) reported forced sexual initiation. After adjustment, independent predictors of forced sexual initiation included being unmarried (aOR, 3.54; 95% CI, 1.22-10.27) and any emotional violence (aOR, 2.47; 95% CI, 1.45-4.24). Those experiencing emotional violence alone (aOR, 3.04; 95% CI: 1.01-9.12), emotional violence in combination with physical or nonpenetrative sexual violence (aOR, 2.50; 95% CI, 1.23-5.09), and emotional violence in combination with physical and nonpenetrative sexual violence (aOR, 2.61; 95% CI, 1.20-5.67) had an increased independent odds of forced sexual initiation. CONCLUSIONS: Experiences of forced sexual initiation are common among Malawian females. Emotional violence is strongly associated with forced sexual initiation, alone and in combination with other forms of childhood violence. The relationship between emotional violence and forced sexual initiation highlights the importance of comprehensive strategies to prevent childhood violence.

RESUMO

Violence is a major public health and human rights concern, claiming over 1.3 million lives globally each year (1). Despite the scope of this problem, population-based data on physical and sexual violence perpetration are scarce, particularly in low-income and middle-income countries (2,3). To better understand factors driving both children becoming victims of physical or sexual violence and subsequently (as adults) becoming perpetrators, CDC collaborated with four countries in sub-Saharan Africa (Malawi, Nigeria, Uganda, and Zambia) to conduct national household surveys of persons aged 13-24 years to measure experiences of violence victimization in childhood and subsequent perpetration of physical or sexual violence. Perpetration of physical or sexual violence was prevalent among both males and females, ranging among males from 29.5% in Nigeria to 51.5% in Malawi and among females from 15.3% in Zambia to 28.4% in Uganda. Experiencing physical, sexual, or emotional violence in childhood was the strongest predictor for perpetrating violence; a graded dose-response relationship emerged between the number of types of childhood violence experienced (i.e., physical, sexual, and emotional) and perpetration of violence. Efforts to prevent violence victimization need to begin early, requiring investment in the prevention of childhood violence and interventions to mitigate the negative effects of violence experienced by children.

RESUMO

More than one billion children - half of all children in the world - are exposed to violence every year. The violence children are exposed to includes both direct experiences of physical, sexual, and emotional abuse, as well as indirectly witnessing violence in their homes, schools, and communities. What these various forms of violence share, based on a review of the literature, is their enduring potential for life-long consequences. These consequences include increases in the risks of injury, HIV, sexually transmitted infections, mental health problems, reproductive health problems, and non-communicable diseases, including cardiovascular disease, cancer, chronic lung disease, and diabetes. Studies addressing biologic underpinnings of such consequences demonstrate that violence-associated toxic stress may cause damage to the nervous, endocrine, circulatory, musculo-skeletal, reproductive, respiratory, and immune systems. Furthermore, rigorous economic evaluations suggest that costs associated with the consequences of violence against children exceed $120 billion in the U.S. and account for up to 3.5% of the GDP in sub-regions of East Asia. The expanding literature confirming the mechanisms of consequences and the associated costs of violence against children has been accompanied by growing evidence on effective approaches to prevention. Moreover, the expanding evidence on prevention has been accompanied by a growing determination on the part of global leaders to accelerate action. Thus, as part of the Post-2015 Sustainable Development agenda, the UN has issued a call-to-action: to eliminate violence against children. This unprecedented UN call may foster new investments, to fuel new progress for protecting children around the world from violence and its preventable consequences.

RESUMO

Naloxone administration is an important component of resuscitation attempts by emergency medical services (EMS) for opioid drug overdoses. However, EMS providers must first recognize the possibility of opioid overdose in clinical encounters. As part of a public health response to an outbreak of opioid overdoses in Rhode Island, we examined missed opportunities for naloxone administration and factors potentially influencing EMS providers' decision to administer naloxone. We reviewed medical examiner files on all individuals who died of an opioid-related drug overdose in Rhode Island from January 1, 2012 through March 31, 2014, underwent attempted resuscitation by EMS providers, and had records available to assess for naloxone administration. We evaluated whether these individuals received naloxone as part of their resuscitation efforts and compared patient and scene characteristics of those who received naloxone to those who did not receive naloxone via chi-square, t-test, and logistic regression analyses. One hundred and twenty-four individuals who underwent attempted EMS resuscitation died due to opioid overdose. Naloxone was administered during EMS resuscitation attempts in 82 (66.1%) of cases. Females were nearly three-fold as likely not to receive naloxone as males (OR 2.9; 95% CI 1.2-7.0; p-value 0.02). Additionally, patients without signs of potential drug abuse also had a greater than three-fold odds of not receiving naloxone (OR 3.3; 95% CI 1.2-9.2; p-value 0.02). Older individuals, particularly those over age 50, were more likely not to receive naloxone than victims younger than age 30 (OR 4.8; 95% CI 1.3-17.4; p-value 0.02). Women, older individuals, and those patients without clear signs of illicit drug abuse, were less likely to receive naloxone in EMS resuscitation attempts. Heightened clinical suspicion for opioid overdose is important given the recent increase in overdoses among patients due to prescription opioids.

RESUMO

BACKGROUND: Little is known about the extent to which HIV-infected street youth (living part or full time on the streets) exhibit behaviors associated with HIV transmission in their interactions with youth not living on the streets ("non-street youth"). We aimed to determine prevalences and predictors of such "bridging behaviors": inconsistent condom use and needle sharing between HIV-positive street youth and non-street youth. METHODS: A total of 171 street youth in 3 Ukrainian cites were identified as HIV infected after testing of eligible participants aged 15 to 24 years after random selection of venues. Using data from these youth, we calculated prevalence estimates of bridging behaviors and assessed predictors using logistic regression. RESULTS: Overall, two-thirds of HIV-infected street youth exhibited bridging behaviors; subgroups with high prevalences of bridging included females (78.3%) and those involved in transactional sex (84.2%). In multivariable analysis, inconsistent condom use with non-street youth was associated with being female (adjusted prevalence ratio [aPR], 1.2; 95% confidence interval [CI], 1.1-1.4), working (aPR, 1.2; 95% CI, 1.03-1.4), multiple partners (aPR, 1.4; 95% CI, 1.2-1.6), and "never" (aPR, 1.4; 95% CI, 1.1-1.6) or "sometimes" (aPR, 1.3; 95% CI, 1.02-1.8) versus "always" sleeping on the street. Needle sharing with non-street youth was associated with being male (aPR, 1.4; 95% CI, 1.02-2.0), orphaned (aPR, 2.3; 95% CI, 1.8-3.0), and 2 years or less living on the streets (aPR, 1.8; 95% CI, 1.5-2.1). CONCLUSIONS: Bridging behaviors between HIV-infected street youth and non-street youth are common. Addressing the comprehensive needs of street and other at-risk youth is a critical prevention strategy.

RESUMO

Sexual violence against children erodes the strong foundation that children require for leading healthy and productive lives. Globally, studies show that exposure to violence during childhood can increase vulnerability to a broad range of mental and physical health problems, ranging from depression and unwanted pregnancy to cardiovascular disease, diabetes, and sexually transmitted diseases, including human immunodeficiency virus (HIV). Despite this, in many countries, the extent of sexual violence against children is unknown; estimates are needed to stimulate prevention and response efforts and to monitor progress. Consequently, CDC, as a member of the global public-private partnership known as Together for Girls, collaborated with Cambodia, Haiti, Kenya, Malawi, Swaziland, Tanzania, and Zimbabwe to conduct national household surveys of children and youth aged 13-24 years to measure the extent of violence against children. The lifetime prevalence of experiencing any form of sexual violence in childhood ranged from 4.4% among females in Cambodia to 37.6% among females in Swaziland, with prevalence in most countries greater than 25.0%. In most countries surveyed, the proportion of victims that received services, including health and child protective services, was ≤10.0%. Both prevention and response strategies for sexual violence are needed.

RESUMO

IMPORTANCE: Interpersonal violence, which includes child abuse and neglect, youth violence, intimate partner violence, sexual violence, and elder abuse, affects millions of US residents each year. However, surveillance systems, programs, and policies to address violence often lack broad, cross-sector collaboration, and there is limited awareness of effective strategies to prevent violence. OBJECTIVES: To describe the burden of interpersonal violence in the United States, explore challenges to violence prevention efforts and to identify prevention opportunities. DATA SOURCES: We reviewed data from health and law enforcement surveillance systems including the National Vital Statistics System, the Federal Bureau of Investigation's Uniform Crime Reports, the US Justice Department's National Crime Victimization Survey, the National Survey of Children's Exposure to Violence, the National Child Abuse and Neglect Data System, the National Intimate Partner and Sexual Violence Survey, the Youth Risk Behavior Surveillance System, and the National Electronic Injury Surveillance System-All Injury Program. RESULTS: Homicide rates have decreased from a peak of 10.7 per 100,000 persons in 1980 to 5.1 per 100,000 in 2013. Aggravated assault rates have decreased from a peak of 442 per 100,000 in 1992 to 242 per 100,000 in 2012. Nevertheless, annually, there are more than 16,000 homicides and 1.6 million nonfatal assault injuries requiring treatment in emergency departments. More than 12 million adults experience intimate partner violence annually and more than 10 million children younger than 18 years experience some form of maltreatment from a caregiver, ranging from neglect to sexual abuse, but only a small percentage of these violent incidents are reported to law enforcement, health care clinicians, or child protective agencies. Moreover, exposure to violence increases vulnerability to a broad range of mental and physical health problems over the life course; for example, meta-analyses indicate that exposure to physical abuse in childhood is associated with a 54% increased odds of depressive disorder, a 78% increased odds of sexually transmitted illness or risky sexual behavior, and a 32% increased odds of obesity. Rates of violence vary by age, geographic location, sex, and race/ethnicity, and significant disparities exist. Homicide is the leading cause of death for non-Hispanic blacks from age 1 through 44 years, whereas it is the fifth most common cause of death among non-Hispanic whites in this age range. Additionally, efforts to understand, prevent, and respond to interpersonal violence have often neglected the degree to which many forms of violence are interconnected at the individual level, across relationships and communities, and even intergenerationally. The most effective violence prevention strategies include parent and family-focused programs, early childhood education, school-based programs, therapeutic or counseling interventions, and public policy. For example, a systematic review of early childhood home visitation programs found a 38.9% reduction in episodes of child maltreatment in intervention participants compared with control participants. CONCLUSIONS AND RELEVANCE: Progress has been made in reducing US rates of interpersonal violence even though a significant burden remains. Multiple strategies exist to improve violence prevention efforts, and health care providers are an important part of this solution.

RESUMO

BACKGROUND: Collateral ventilation has been proposed as a mechanism of compensation of respiratory function in obstructive lung diseases but observations of it in vivo are limited. The assessment of collateral ventilation with an imaging technique might help to gain insight into lung physiology and assist the planning of new bronchoscopic techniques for treating emphysema. OBJECTIVE: To obtain images of delayed ventilation that might be related to collateral ventilation over the period of a single breath-hold in patients with chronic obstructive pulmonary disease (COPD). METHODS: Time-resolved breath-hold hyperpolarised (3)He MRI was used to obtain images of the progressive influx of polarised gas into initially non-ventilated defects. RESULTS: A time-series of images showed that (3)He moves into lung regions which were initially non-ventilated. Ventilation defects with delayed filling were observed in 8 of the 10 patients scanned. CONCLUSIONS: A method for direct imaging of delayed ventilation within a single breath-hold has been demonstrated in patients with COPD. Images of what is believed to be collateral ventilation and slow filling of peripheral airspaces due to increased flow resistance are presented. The technique provides 3D whole-lung coverage with sensitivity to regional information, and is non-invasive and non-ionising.

RESUMO

BACKGROUND: In the 6 months following our estimates from March 1, 2020, to April 30, 2021, the proliferation of new coronavirus variants, updated mortality data, and disparities in vaccine access increased the amount of children experiencing COVID-19-associated orphanhood. To inform responses, we aimed to model the increases in numbers of children affected by COVID-19-associated orphanhood and caregiver death, as well as the cumulative orphanhood age-group distribution and circumstance (maternal or paternal orphanhood). METHODS: We used updated excess mortality and fertility data to model increases in minimum estimates of COVID-19-associated orphanhood and caregiver deaths from our original study period of March 1, 2020-April 30, 2021, to include the new period of May 1-Oct 31, 2021, for 21 countries. Orphanhood was defined as the death of one or both parents; primary caregiver loss included parental death or the death of one or both custodial grandparents; and secondary caregiver loss included co-residing grandparents or kin. We used logistic regression and further incorporated a fixed effect for western European countries into our previous model to avoid over-predicting caregiver loss in that region. For the entire 20-month period, we grouped children by age (0-4 years, 5-9 years, and 10-17 years) and maternal or paternal orphanhood, using fertility contributions, and we modelled global and regional extrapolations of numbers of orphans. 95% credible intervals (CrIs) are given for all estimates. FINDINGS: The number of children affected by COVID-19-associated orphanhood and caregiver death is estimated to have increased by 90·0% (95% CrI 89·7-90·4) from April 30 to Oct 31, 2021, from 2 737 300 (95% CrI 1 976 100-2 987 000) to 5 200 300 (3 619 400-5 731 400). Between March 1, 2020, and Oct 31, 2021, 491 300 (95% CrI 485 100-497 900) children aged 0-4 years, 736 800 (726 900-746 500) children aged 5-9 years, and 2 146 700 (2 120 900-2 174 200) children aged 10-17 years are estimated to have experienced COVID-19-associated orphanhood. Globally, 76·5% (95% CrI 76·3-76·7) of children were paternal orphans, whereas 23·5% (23·3-23·7) were maternal orphans. In each age group and region, the prevalence of paternal orphanhood exceeded that of maternal orphanhood. INTERPRETATION: Our findings show that numbers of children affected by COVID-19-associated orphanhood and caregiver death almost doubled in 6 months compared with the amount after the first 14 months of the pandemic. Over the entire 20-month period, 5·0 million COVID-19 deaths meant that 5·2 million children lost a parent or caregiver. Our data on children's ages and circumstances should support pandemic response planning for children globally.

RESUMO

BACKGROUND: The HIV epidemic in Russia has increasingly involved reproductive-aged women, which may increase perinatal HIV transmission. METHODS: Standard HIV case-reporting and enhanced perinatal HIV surveillance systems were used for prospective assessment of HIV-infected women giving birth in St. Petersburg, Russia, during 2004-2008. Trends in social, perinatal, and clinical factors influencing mother-to-child HIV transmission stratified by history of injection drug use, and rates of perinatal HIV transmission were assessed using two-sided χ2 or Cochran-Armitage tests. RESULTS: Among HIV-infected women who gave birth, the proportion of women who self-reported ever using injection drugs (IDUs) decreased from 62% in 2004 to 41% in 2008 (P<0.0001). Programmatic improvements led to increased uptake of the following clinical services from 2004 to 2008 (all P<0.01): initiation of antiretroviral prophylaxis at ≤28 weeks gestation (IDUs 44%-54%, non-IDUs 45%-72%), monitoring of immunologic (IDUs 48%-64%, non-IDUs 58%-80%) and virologic status (IDUs 8%-58%, non-IDUs 10%-75%), dual/triple antiretroviral prophylaxis (IDUs 9%-44%, non-IDUs 14%-59%). After initial increase from 5.3% (95% confidence interval [CI] 3.5%-7.8%) in 2004 to 8.5% (CI 6.1%-11.7%) in 2005 (P<0.05), perinatal HIV transmission decreased to 5.3% (CI 3.4%-8.3%) in 2006, and 3.2% (CI 1.7%-5.8%) in 2007 (P for trend<0.05). However, the proportion of women without prenatal care and without HIV testing before labor and delivery remained unchanged. CONCLUSIONS: Reduced proportion of IDUs and improved clinical services among HIV-infected women giving birth were accompanied by decreased perinatal HIV transmission, which can be further reduced by increasing outreach and HIV testing of women before and during pregnancy.

RESUMO

Although street youth are at increased risk of lifetime pregnancy involvement (LPI), or ever becoming or getting someone pregnant, no reports to date describe the epidemiology of LPI among systematically sampled street youth from multiple cities outside of North America. The purpose of our assessment was to describe the prevalence of and risk factors associated with LPI among street youth from three Ukrainian cities. We used modified time-location sampling to conduct a cross-sectional assessment in Odesa, Kyiv, and Donetsk that included citywide mapping of 91 public venue locations frequented by street youth, random selection of 74 sites, and interviewing all eligible and consenting street youth aged 15-24 years found at sampled sites (n = 929). Characteristics of youth and prevalence of LPI overall and by demographic, social, sexual, and substance use risk factors, were estimated separately for males and females. Adjusted odds ratios (AORs) were calculated with multivariable logistic regression and effect modification by gender was examined. Most (96.6%) eligible youth consented to participate. LPI was reported for 41.7% of females (93/223) and 23.5% of males (166/706). For females, LPI was significantly elevated and highest (>70%) among those initiating sexual activity at ≤12 years and for those reporting lifetime anal sex and exchanging sex for goods. For males, LPI was significantly elevated and highest (>40%) among those who reported lifetime anal sex and history of a sexually transmitted infection. Overall, risk factors associated with LPI were similar for females and males. Among the total sample (females and males combined), significant independent risk factors with AORs ≥2.5 included female gender, being aged 20-24 years, having five to six total adverse childhood experiences, initiating sex at age ≤12 or 13-14 years, lifetime anal sex, most recent sex act unprotected, and lifetime exchange of sex for goods. Among street youth with LPI (n = 259), the most recent LPI event was reported to be unintended by 63.3% and to have ended in abortion by 43.2%. In conclusion, our assessment documented high rates of LPI among Ukrainian street youth who, given the potential for negative outcomes and the challenges of raising a child on the streets, are in need of community-based pregnancy prevention programs and services. Promising preventive strategies are discussed, which are likely applicable to other urban populations of street-based youth as well.

RESUMO

Community violence is a prevalent form of interpersonal violence in South Africa for children living in low-income areas. Trauma arising from violence exposure is of concern in contexts where access to treatment is often unattainable. As simultaneous multisectoral strategies show higher potential to counter interpersonal violence than single interventions, the World Health Organization with partners created INSPIRE. INSPIRE takes an integrated approach coordinated across formal and informal settings of civil and private society. Responding to research paucity on methods that counter community violence in LMIC settings, this study employed a cross-sectional correlational design consisting of a sample of 2,477 children aged 10 to 17 years from the Young Carers 2009-2010 study conducted in a low-income, HIV-endemic province of South Africa highly affected by community violence. Multiple logistic regressions assessed individual and dose associations between four INSPIRE-based violence prevention strategies-positive parenting, basic necessities, formal social support, and school structural support-and direct and indirect community violence outcomes. Three strategies had significant associations with community violence outcomes: necessities (direct p < .001; adjusted odds ratio [AOR] = .57; indirect p < .01; AOR = .62), formal support (direct p < .05; AOR = .83; indirect p < .05; AOR = .73), and school support (direct p < .001; AOR = .53; indirect p < .001; AOR = .49). Combined interventions in direct and indirect community violence analyses demonstrated that children reporting a higher number of strategies were less likely to have experienced community violence. This outcome extends the results of longitudinal studies in South Africa highlighting social protection with care as a means to overcome structural deprivation strains, thereby reducing the likelihood of children's exposure to community violence. Moreover, these findings uphold the INSPIRE model as an effective cross-sectoral approach to prevent and reduce the community violence that children experience.

RESUMO

PURPOSE: Youth suicide clusters may be exacerbated by suicide contagion-the spread of suicidal behaviors. Factors promoting suicide contagion are poorly understood, particularly in the advent of social media. Using cross-sectional data from an ongoing youth suicide cluster in Ohio, this study examines associations between suicide cluster-related social media and suicidal behaviors. METHODS: We surveyed 7th- to 12th-grade students in northeastern Ohio during a 2017-2018 suicide cluster to assess the prevalence of suicidal ideation (SI), suicide attempts (SAs), and associations with potential contagion-promoting factors such as suicide cluster-related social media, vigils, memorials, news articles, and watching the Netflix series 13 Reasons Why before or during the cluster. Generalized estimating equations examined associations between potential contagion-promoting factors and SI/SA, adjusting for nonmodifiable risk factors. Subgroup analyses examined whether associations between cluster-related factors and SI/SA during the cluster varied by previous history of SI/SA. RESULTS: Among participating students, 9.0% (876/9,733) reported SI and 4.9% attempted suicide (481/9,733) during the suicide cluster. Among students who posted suicide cluster-related content to social media, 22.9% (267/1,167) reported SI and 15.0% (175/1,167) attempted suicide during the suicide cluster. Posting suicide cluster-related content was associated with both SI (adjusted odds ratio 1.7, 95% confidence interval 1.4-2.0) and SA during the cluster (adjusted odds ratio 1.7, 95% confidence interval 1.2-2.5). In subgroup analyses, seeing suicide cluster-related posts was uniquely associated with increased odds of SI and SA during the cluster among students with no previous history of SI/SA. CONCLUSIONS: Exposure to suicide cluster-related social media is associated with both SI and SA during a suicide cluster. Suicide interventions could benefit from efforts to mitigate potential negative effects of social media and promote prevention messages.

RESUMO

BACKGROUND: Most coronavirus disease 2019 (COVID-19) deaths occur among adults, not children, and attention has focused on mitigating COVID-19 burden among adults. However, a tragic consequence of adult deaths is that high numbers of children might lose their parents and caregivers to COVID-19-associated deaths. METHODS: We quantified COVID-19-associated caregiver loss and orphanhood in the United States and for each state using fertility and excess and COVID-19 mortality data. We assessed burden and rates of COVID-19-associated orphanhood and deaths of custodial and coresiding grandparents, overall and by race and ethnicity. We further examined variations in COVID-19-associated orphanhood by race and ethnicity for each state. RESULTS: We found that from April 1, 2020, through June 30, 2021, >140 000 children in the United States experienced the death of a parent or grandparent caregiver. The risk of such loss was 1.1 to 4.5 times higher among children of racial and ethnic minority groups compared with non-Hispanic White children. The highest burden of COVID-19-associated death of parents and caregivers occurred in Southern border states for Hispanic children, in Southeastern states for Black children, and in states with tribal areas for American Indian and/or Alaska Native populations. CONCLUSIONS: We found substantial disparities in distributions of COVID-19-associated death of parents and caregivers across racial and ethnic groups. Children losing caregivers to COVID-19 need care and safe, stable, and nurturing families with economic support, quality child care, and evidence-based parenting support programs. There is an urgent need to mount an evidence-based comprehensive response focused on those children at greatest risk in the states most affected.

RESUMO

OBJECTIVE: The purpose of this study was to examine trends in hospitalizations for gynecologic disorders in the United States. STUDY DESIGN: Data on hospitalizations from 1998-2005 among women 15-54 years old were from the Nationwide Inpatient Sample, a nationally representative survey of inpatient hospitalizations. Hospitalizations with a principal diagnosis of a gynecologic disorder were used to estimate rates per 10,000 women. RESULTS: Gynecologic disorders accounted for 7% and 14% of all hospitalizations among women 15-44 and 45-54 years old, respectively. The most common diagnoses were uterine leiomyomas (rate = 27.5), menstrual disorders (rate = 12.3), endometriosis (rate = 9.5), genital prolapse (rate = 7.0), benign ovarian cysts (rate = 6.5), and pelvic inflammatory disease (rate = 6.1). The hospitalization rate for menstrual disorders increased from 9.8 in 1998 to 13.3 in 2005 (P trend < .001). In contrast, rates declined for pelvic inflammatory disease, genital prolapse, benign ovarian cysts, and endometriosis (P trend < .05) and were unchanged for uterine leiomyoma. CONCLUSION: Gynecologic disorders are an important contributor to inpatient hospitalization among women in the United States.

RESUMO

OBJECTIVE: To examine trends in the rates of severe obstetric complications and the potential contribution of changes in delivery mode and maternal characteristics to these trends. METHODS: We performed a cross-sectional study of severe obstetric complications identified from the 1998-2005 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project. Logistic regression was used to examine the effect of changes in delivery mode and maternal characteristics on rates of severe obstetric complications. RESULTS: The prevalence of delivery hospitalizations (per 1,000) complicated by at least one severe obstetric complication increased from 0.64% (n=48,645) in 1998-1999 to 0.81% (n=68,433) in 2004-2005. Rates of complications that increased significantly during the study period included renal failure by 21% (from 0.23 to 0.28), pulmonary embolism by 52% (0.12 to 0.18), adult respiratory distress syndrome by 26% (0.36 to 0.45), shock by 24% (0.15 to 0.19), blood transfusion by 92% (2.38 to 4.58), and ventilation by 21 % (0.47 to 0.57). In logistic regression models, adjustment for maternal age had no effect on the increased risk for these complications in 2004-2005 relative to 1998-1999. However, after adjustment for mode of delivery, the increased risks for these complications in 2004-2005 relative to 1998-1999 were no longer significant, with the exception of pulmonary embolism (odds ratio 1.30) and blood transfusion (odds ratio 1.72). Further adjustment for payer, multiple births, and select comorbidities had little effect. CONCLUSION: Rates of severe obstetric complications increased from 1998-1999 to 2004-2005. For many of these complications, these increases were associated with the increasing rate of cesarean delivery. LEVEL OF EVIDENCE: III.
