Violence, abuse, and asthma in Puerto Rican children

Abuse during childhood and adolescence and risk of adult-onset asthma in African American women

BACKGROUND

Experiences of violence contribute to the occurrence of childhood asthma, but there is little information on the effect of early-life abuse on adult-onset asthma.

OBJECTIVE

We prospectively assessed the relation between physical and sexual abuse during childhood and adolescence and the incidence of adult-onset asthma in the Black Women's Health Study.

METHODS

We followed 28,456 women from 1995 through 2011 with biennial mailed questionnaires. Experiences of physical and sexual abuse that occurred during childhood and adolescence were obtained in 2005. Cox regression models were used to estimate incidence rate ratios (IRRs) and 95% CIs.

RESULTS

During 417,931 person-years of follow-up, 1,160 participants reported physician-diagnosed asthma and concurrent use of asthma medication. Compared with women who experienced no abuse during childhood or adolescence, the multivariable IRR for any childhood abuse was 1.24 (95% CI, 1.06-1.45), and for any adolescent abuse, it was 1.10 (95% CI, 0.88-1.36). The IRR was higher for childhood physical abuse (IRR, 1.29; 95% CI, 1.07-1.49) than for childhood sexual abuse (IRR, 1.15; 95% CI, 0.88-1.49). IRRs for physical and sexual abuse during adolescence were compatible with 1.0. The association between childhood abuse and asthma incidence was stronger in older compared with younger women.

CONCLUSION

In this large cohort of African American women, there was a positive association between adult-onset asthma and childhood physical abuse and weaker associations for childhood sexual abuse and any abuse during adolescence. Given the high prevalence of asthma and childhood abuse, this association is of public health importance.

A population study of childhood maltreatment and asthma diagnosis: differential associations between child protection database versus retrospective self-reported data

OBJECTIVE

Despite growing evidence from longitudinal studies of a link between early-life stress and the development of asthma, very few of these examine one of the most severe types of early-life stress: childhood maltreatment. Cross-sectional studies on this topic have relied on retrospective self-reports of maltreatment. This study investigates associations between childhood maltreatment indicated by child protection agency records versus self-reports and lifetime asthma diagnosis in young adults, adjusting for socioeconomic status and mental disorders.

METHODS

A nationally representative general population survey of DSM-IV mental disorders in New Zealand (n = 12,992) obtained information on lifetime diagnoses of chronic physical conditions. Information from a subsample of survey respondents aged 16 to 27 years (n = 1413) was linked with a national child protection database to identify respondents with a history of agency involvement, which was used as a proxy for childhood maltreatment. Retrospective reports of maltreatment were also obtained.

RESULTS

Child protection agency history was associated with elevated odds (odds ratio = 2.88 [95% confidence interval = 1.7-4.74]) of a lifetime diagnosis of asthma. After adjusting for a variety of indicators of socioeconomic status, lifetime mental disorders, lifetime smoking, and body mass index, this association remained significantly elevated (odds ratio = 2.26 [95% confidence interval = 1.33-3.83]). Retrospectively self-reported maltreatment in childhood was not associated with asthma.

CONCLUSIONS

Childhood maltreatment was associated with elevated odds of asthma diagnosis. These findings are consistent with the possibility that early-life stress may be one of the environmental factors that increase the risk of asthma in genetically vulnerable individuals.

Recruitment, asthma characteristics, and medication behaviors in Midwestern Puerto Rican youth: data from Project CURA

BACKGROUND

Puerto Rican children have the highest prevalence of asthma, but detailed descriptions of this population have been limited to the island of Puerto Rico and the northeastern United States.

OBJECTIVE

To describe the asthma characteristics of this urban Midwest cohort of Puerto Rican youth, focusing on medication behaviors, and to test whether their asthma outcomes are associated with their demographic and psychosocial variables.

METHODS

Data are from the baseline cohorts of a randomized controlled trial designed to improve medication adherence in Puerto Rican youth. Recruitment used a community-based participatory research approach. Data were collected in the home. Medications and medication technique were visually assessed, and adherence was determined using electronic medication monitors or counters. Data on asthma symptoms and morbidity, demographics, and psychosocial factors were collected.

RESULTS

The recruitment of 101 participants (51 in elementary school and 50 in high school) was completed in 14 months. Despite overall high asthma severity and poor asthma control, 20% of participants had no reliever medicine in their home. Self-report of controller use was higher than actual controller medications visualized in the home. For those who had an inhaled corticosteroid medicine (only 45% of elementary school participants and 12% of high school participants), median adherence was 1.0 doses per day. Rates of depression and stress were very high among both caregivers and children.

CONCLUSION

Puerto Rican youth in the Midwest bear a significant asthma burden in addition to other stressors, including depression. Visual inspection of medications and monitoring of adherence are critical for understanding asthma morbidity in this high-risk population.

Socioeconomic status and the health of youth: a multilevel, multidomain approach to conceptualizing pathways

Previous research has clearly established associations between low socioeconomic status (SES) and poor youth physical health outcomes. This article provides an overview of the main pathways through which low SES environments come to influence youth health. We focus on 2 prevalent chronic health problems in youth today, asthma and obesity. We review and propose a model that encompasses (a) multiple levels of influence, including the neighborhood, family and person level; (b) both social and physical domains in the environment; and finally (c) dynamic relationships between these factors. A synthesis of existing research and our proposed model draw attention to the notion of adverse physical and social exposures in youth's neighborhood environments altering family characteristics and youth psychosocial and behavioral profiles, thereby increasing youth's risk for health problems. We also note the importance of acknowledging reciprocal influences across levels and domains (e.g., between family and child) that create self-perpetuating patterns of influence that further accentuate the impact of these factors on youth health. Finally, we document that factors across levels can interact (e.g., environmental pollution levels with child stress) to create unique, synergistic effects on youth health. Our model stresses the importance of evaluating influences on youth's physical health not in isolation but in the context of the broader social and physical environments in which youth live. Understanding the complex relationships between the factors that link low SES to youth's long-term health trajectories is necessary for the creation and implementation of successful interventions and policies to ultimately reduce health disparities.

Physiologic changes associated with violence and abuse exposure: an examination of related medical conditions

Although the extant evidence is replete with data supporting linkages between exposure to violence or abuse and the subsequent development of medical illnesses, the underlying mechanisms of these relationships are poorly defined and understood. Physiologic changes occurring in violence- or abuse-exposed individuals point to potentially common biological pathways connecting traumatic exposures with medical outcomes. Herein, the evidence describing the long-term physiologic changes in abuse- and violence-exposed populations and associated medical illnesses are reviewed. Current data support that (a) specific neurobiochemical changes are associated with exposure to violence and abuse; (b) several biological pathways have the potential to lead to the development of future illness; and (c) common physiologic mechanisms may moderate the severity, phenomenology, or clinical course of medical illnesses in individuals with histories of exposure to violence or abuse. Importantly, additional work is needed to advance our emerging understanding of the biological mechanisms connecting exposure to violence and abuse and negative health outcomes.

Childhood physical abuse and respiratory disease in the community: the role of mental health and cigarette smoking

INTRODUCTION

Previous studies have found an association between child abuse and respiratory disease in some populations, but the mechanisms remain unknown, and this association has not been examined in a representative community-based sample. The goal of this study was to examine the relationship between childhood physical abuse and the odds of respiratory disease and to investigate the role of depression, anxiety, and pack-years of smoking in this association.

METHODS

Data were drawn from the Midlife Development in the United States Survey (n = 3,032), a representative sample of adults aged 25-74 years. Multiple logistic regression analyses were used to determine the association between childhood abuse and current respiratory disease (past 12 months) and to examine whether pack-years of smoking, depression, and anxiety disorders mediated the relationship.

RESULTS

Individuals who often experienced childhood abuse had a significantly increased odds of respiratory disease (odds ratio [OR] = 1.87 [1.21, 2.90]). The association was attenuated, after adjusting for demographic characteristics and pack-years of smoking, and was no longer significant after adjusting for depression and anxiety disorders.

CONCLUSIONS

These results are consistent with previous data suggesting a significant association between childhood abuse and respiratory disease and extend existing knowledge by providing initial evidence that demographic differences, depression and anxiety disorders, and lifetime cigarette smoking may mediate this observed relationship. Results require replication with longitudinal data in large community-based samples. Future studies that can explore potential biological mechanisms underlying the observed associations, such as immune factors, are needed next to better understand these relationships.

Social environment and asthma: associations with crime and No Child Left Behind programmes

BACKGROUND

The relationship between asthma and socio-economic status remains unclear. The authors investigated how neighbourhood, school and community social environments were associated with incident asthma in Southern California schoolchildren.

METHODS

New-onset asthma was measured over 3 years of follow-up in the Children's Health Study cohort. Multilevel random-effects models assessed associations between social environments and asthma, adjusted for individual risk factors. At baseline, subjects resided in 274 census tracts (ie, neighbourhoods) and attended kindergarten or first grade in one of 45 schools distributed in 13 communities throughout Southern California. Neighbourhoods and communities were characterised by measures of deprivation, income inequality and racial segregation. Communities were further described by crime rates. Information on schools included whether a school received funding related to the Title 1 No Child Left Behind programme, which aims to reduce academic underachievement in disadvantaged populations.

RESULTS

Increased risk for asthma was observed in subjects attending schools receiving Title I funds compared with those from schools without funding (adjusted HR 1.71, 95% CI 1.14 to 2.58), and residing in communities with higher rates of larceny crime (adjusted HR 2.02, 95% CI 1.08 to 3.02 across the range of 1827 incidents per 100,000 population).

CONCLUSIONS

Risk for asthma was higher in areas of low socio-economic status, possibly due to unmeasured risk factors or chronic stress.

Crime, neighborhood deprivation, and asthma: a GIS approach to define and assess neighborhoods

Exposure to neighborhood factors remains difficult to quantify when neighborhoods are often predefined and imprecisely measured. This study examines the association between neighborhood deprivation and participation in a community-based asthma case management (CM) program in Oakland, CA. We estimated neighborhoods by calculating walking distances of , and miles around each child's (n=2892) residence. The model assesses deprivation by the addition of weighted factors within a child's neighborhood-crime rates, alcohol outlets, and eight 2000 US Census characteristics. The results illustrate that neighborhood deprivation is weakly associated with greater levels of program participation, but neighborhood education level, measured by percentage of residents with less than a high school education, is strongly associated with greater program participation (OR: 4.43, 95% CI: [1.23, 15.99]). Neighborhood deprivation factors were significantly different between neighborhoods defined by walking distances and census blockgroups (Wilcoxon-signed rank test: p<0.05).

Exposure to community violence is associated with asthma hospitalizations and emergency department visits

BACKGROUND

Exposure to community violence (ECV) has been associated with asthma morbidity of children living in inner-city neighborhoods.

OBJECTIVE

To examine with prospective longitudinal data whether ECV is independently associated with asthma-related health outcomes in adults.

METHODS

Adults with moderate-severe asthma, recruited from clinics serving inner-city neighborhoods, completed questionnaires covering sociodemographics, asthma severity, and ECV and were followed for 26 weeks. Longitudinal models were used to assess unadjusted and adjusted associations of subsequent asthma outcomes (emergency department [ED] visits, hospitalizations, FEV(1), quality of life).

RESULTS

A total of 397 adults, 47 +/- 14 years old, 73% women, 70% African American, 7% Latino, mean FEV(1) 66% +/- 19%, 133 with hospitalizations and 222 with ED visits for asthma in the year before entry, were evaluated. Ninety-one reported ECV. Controlling for age, sex, race/ethnicity, and household income, those exposed to violence had 2.27 (95% CI, 1.32-3.90) times more asthma-related ED visits per month and 2.49 (95% CI, 1.11-5.60) times more asthma-related hospitalizations per month over the 26-week study period compared with those unexposed. Violence-exposed participants also had 1.71 (95% CI, 1.14-2.56) times more overall ED visits per month and 1.72 (95% CI, 0.95-3.11) times more overall hospitalizations per month from any cause. Asthma-related quality of life was lower in the violence-exposed participants (-0.40; 95% CI, -0.77 to -0.025; P = .04). Effect modification by depressive symptoms was only statistically significant for the ECV association with overall ED visits and quality-of-life outcomes (P < .01).

CONCLUSION

In adults, ECV is associated with increased asthma hospitalizations and emergency care for asthma or any condition and with asthma-related quality of life.

The association between community crime and childhood asthma prevalence in Chicago

BACKGROUND

Little attention has been given to exposure to crime as a possible socioenvironmental contributor to variability in urban childhood asthma prevalence.

OBJECTIVE

To determine the association of violent crime, property crime, and drug abuse violations with childhood asthma prevalence in Chicago.

METHODS

In 2003-2005, the Chicago Initiative to Raise Asthma Health Equity conducted an asthma screening survey of children in grades K to 8 attending Chicago public and Catholic schools. Crime data were obtained from the Chicago Police Department. In addition to simple regression analysis, multilevel logistic regression analysis was performed to estimate the effect of criminal activity on neighborhood asthma variance.

RESULTS

Of the surveys returned, 45,371 (93%) were geocoded into 247 neighborhoods. Neighborhoods were divided into quartile groups by mean asthma prevalence (9%, 12%, 17%, and 22%). Criminal activity (annual incidence per 100,000 people) was significantly higher (P < .001) in neighborhoods with a high asthma prevalence, especially drug abuse violations, which increased more than 6-fold (461 vs 2,921), and violent crimes, which increased more than 3-fold (448 vs 1,566). After adjusting for community race/ethnicity, only violent crime continued to be significantly associated with the neighborhood asthma prevalence (odds ratio, 1.27; 95% confidence interval, 1.04-1.55, P < .05). When considered alongside sociodemographic and individual characteristics, violence continued to contribute significantly (P < .05), explaining 15% of neighborhood variation in childhood asthma.

CONCLUSIONS

Evidence suggests an association between violent crime and childhood asthma prevalence in Chicago. A deeper understanding of the mechanisms that underlie this association may lend insight into potential interventions to address urban asthma.

Feasibility of collecting biologic specimens in population-based surveys: experiences from the epidemiology of hepatitis C in the household, adult population of Puerto Rico study

The Behavioral Risk Factor Surveillance System (BRFSS) collects data on preventive health practices and risk behaviors that are linked to chronic diseases, injuries, and preventable infectious diseases that affect the adult population in all states and territories in the US. The BRFSS is currently the only survey conducted annually in Puerto Rico in the population aged 18 years and older; however, prevalence estimates are based on self-reports and therefore are subject to reporting errors. Although surveillance data are useful for the purpose of evaluation, program planning and health policy, surveys that collect biological specimens and clinical data provide a more accurate assessment of prevalence and a comprehensive picture of disease distribution and their risk factors. This article summarizes the methodology employed in a population-based study to estimate the seroprevalence of hepatitis C and other viral infections in Puerto Rico and shows the feasibility of combining different modes of data collection in population-based surveys that collect biologic specimens.

Child maltreatment and pediatric health outcomes: a longitudinal study of low-income children

OBJECTIVE

To examine if maltreatment predicted increased risk of hospital-based treatment prior to age 18 years for asthma, cardio-respiratory, and non-sexually transmitted infectious disease in a sample of low-income children.

METHODS

This study used administrative data from multiple systems to follow children for 12-18 years (N = 6,282). Cox regression was used to explore the risk of first hospital treatment by disease category. Negative binomial regression was used to explore the relationship between recurrent maltreatment and total hospital care episodes.

RESULTS

Controlling for individual, family, and community factors, children with maltreatment reports had a 74-100% higher risk of hospital treatment. Recurrent reports predicted a higher count of hospital care episodes.

CONCLUSIONS

The negative health impact of maltreatment prior to adulthood supports the need for early prevention and intervention to prevent initial and recurrent child abuse and improve capacity to meet healthcare needs of maltreated children.

Asthma and ethnic minorities: socioeconomic status and beyond

PURPOSE OF REVIEW

We aim to discuss current insights into our understanding of the mechanisms by which socioeconomic status influences the prevalence and severity of asthma in ethnic minorities. In addition, we review potential risk factors for ethnic disparities in asthma that are not mediated by socioeconomic status.

RECENT FINDINGS

Exposures and factors correlated with ethnicity through socioeconomic status (e.g. indoor and outdoor air quality, smoke exposure, and access to healthcare) are likely to explain a significant proportion of the observed ethnic differences in asthma morbidity. However, other factors correlated with ethnicity (e.g. genetic variation) can impact ethnic disparities in asthma independently of and/or interacting with socioeconomic status-related factors.

SUMMARY

Socioeconomic status is a rough marker of a variety of environmental/behavioral exposures and a very important determinant of differences in asthma prevalence and severity among ethnic minorities in the United States. However, socioeconomic status is unlikely to be the sole explanation for ethnic disparities in asthma, which may also be due to differences in genetic variation and gene-by-environment interactions among ethnic groups.

Update on child maltreatment

PURPOSE OF REVIEW

The authors explore the literature published in the past year addressing child maltreatment issues, including sexual abuse, physical child abuse, inflicted head trauma, and child abuse prevention.

RECENT FINDINGS

The body of knowledge about child abuse and its mimics continues to expand. Evident in this year's literature is the challenge which the diagnosis of child abuse creates for clinicians. Although further strides are being made toward universal education of providers, it is clear that there is still a reluctance to report abuse to child welfare agencies. The legal repercussions of diagnosing abuse can be extensive, and there has been a proliferation of medical defense experts who disagree with the commonly accepted tenets of abusive injury and who are vocal in the literature.

SUMMARY

It remains the responsibility of pediatric providers to consider child maltreatment in the differential diagnosis of any unexplained injury or medical problem. Several studies document the high rate of spanking, slapping or shaking children, and primary care clinicians may be the first professionals in a position to begin the evaluation for possible child maltreatment. Despite the natural hesitancy to diagnose abuse, clinicians have an ethical and moral obligation to address this issue both in their practice and in their communities. The short-term and long-term costs to individuals who experience family violence have been well demonstrated and include not only emotional repercussions, but also chronic health conditions, which result in significant cost to society.

Increased levels of outdoor air pollutants are associated with reduced bronchodilation in children with asthma

BACKGROUND

Increased outdoor air pollution levels are associated with more frequent use of rescue inhalers in subjects with asthma. However, it is unknown whether this phenomenon is explained by an air pollution-mediated increase in respiratory symptom severity or whether air pollutants decrease the efficacy of short-acting beta-agonists (SABAs).

METHODS

We examined the relationship between the percentage change in FEV(1) after SABA use with outdoor air pollution exposure in 85 children with asthma who were 7 to 12 years of age. Outdoor air pollution exposure was determined by measuring nitrogen dioxide (NO(2)), ozone (O(3)), and fine particulate matter (ie, particulate matter with an aerodynamic diameter < 2.5 microm [PM(2.5)]) levels. These measurements were obtained from the Mexico City Automated Monitoring Network from network sites located within a 5-km radius of each child's home and school.

RESULTS

We found that a same-day interquartile increase of 10 parts per billion (ppb) in NO(2) concentration was associated with a reduced response of FEV(1) to SABA therapy (-15%; 95% CI, -29 to -0.5). This association was also significant when considering NO(2) levels in each of the preceding 3 days. An interquartile O(3) increase (16 ppb) in the preceding fifth day was associated with a reduced response to SABA (-11%; 95% CI, -23 to -1); an interquartile PM(2.5) increase (14 microg/m(3)) was not associated with any significant reductions in the response to SABA therapy. These associations were not observed in children receiving therapy with inhaled corticosteroids.

CONCLUSIONS

Our results suggest that recent exposure to NO(2) and possibly O(3) may reduce the response to SABAs in producing bronchodilation in children with asthma. The association between NO(2) and FEV(1) response to SABA administration may have important implications in understanding how outdoor air pollution levels relate to asthma control.

Eliminating asthma disparities: is there evidence of progress?

PURPOSE OF REVIEW

In spite of numerous efforts, asthma rates in the United States remain historically high and disparities persist among low-income and minority populations. This review assesses the current status of asthma inequities from the perspective of disease development, progression, and outcomes.

RECENT FINDINGS

Recent findings highlight the complex and multifactorial nature of asthma. There is a clear line of emerging evidence suggestive of important hierarchical relationships between the predisposed or affected individual and his or her intrapersonal life, familial relationships, social networks, and broader community.

SUMMARY

Approaches in basic, clinical, and translational asthma research must be modified to account for the social construct of race and to detangle complex interactions of contributing factors at and across the individual and community level. However, there are a number of obvious opportunities to dramatically reduce asthma disparities at hand.

Violence and Asthma: A Review

Recent research shows that exposure to community violence is, directly and indirectly, associated with asthma. This article reviews the findings on the impact of violence on asthma, and the pathways for the association of violence and asthma are suggested: 1) exposure to violence is directly associated with asthma, mainly through dysregulation of sympathetic-adrenal-medullary (SAM) and hypothalamic-pituitary-adrenal (HPA) axis, 2) exposure to violence is associated with the change of susceptibility of outdoor air pollution on asthma, probably through the change of an immune response, and 3) behavioral change due to exposure to violence (e.g. keeping children indoors) leads to more exposure to indoor pollutants. The suggested framework may be useful to develop health policy on asthma in high-violence communities.
