Asthma and Serious Psychological Distress: Prevalence and Risk Factors Among US Adults, 2001-2007

BACKGROUND For millions of adults, effective control of asthma requires a regimen of care that may be compromised by psychological factors, such as anxiety and depression. This study estimated the prevalence and risk factors for serious psychological distress (SPD) and explored their relationship to health-related quality of life (HRQOL) among adults with asthma in the United States. METHODS We analyzed data from 186,738 adult respondents from the 2001-2007 US National Health Interview Survey. We calculated weighted average prevalence estimates of current asthma and SPD by demographic characteristics and health-related factors. We used logistic regression analysis to calculate odds ratios for factors that may have predicted asthma, SPD, and HRQOL. RESULTS From 2001 to 2007, the average annual prevalence of current asthma was 7.0% and the average prevalence of SPD was 3.0%. Among adults with asthma, the prevalence of SPD was 7.5% (95% CI, 7.0%-8.1%). A negative association between HRQOL and SPD was found for all adults, independent of asthma status. A similar pattern of risk factors predicted SPD and the co-occurrence of SPD and asthma, although adults with asthma who reported lower socioeconomic status, a history of smoking or alcohol use, and more comorbid chronic conditions had significantly higher odds of SPD. CONCLUSION This research suggests the importance of mental health screening for persons with asthma and the need for clinical and community-based interventions to target modifiable lifestyle factors that contribute to psychological distress and make asthma worse.

Racial and Ethnic Disparities in Current Asthma and Emergency Department Visits: Findings from the National Health Interview Survey, 2001–2010

Objectives. Racial/ethnic disparities in current asthma prevalence and medical care are a major public health concern. We examined the differences in asthma prevalence and morbidity among major racial/ethnic populations in the US. Methods. We analyzed data from the 2001–2010 National Health Interview Survey for adults (≥18 years) and children and adolescents (<18 years). Outcome variables were current asthma prevalence, at least one attack in the past 12 months, and at least one asthma-related emergency department/urgent care center (ED/UCC) visit in the past 12 months. We used multivariate logistic regression to calculate the model-adjusted prevalence and risk ratios (ARR). Results. In our study, 9.0% of the children and 7.2% of the adults had current asthma. Non-Hispanic black and Puerto Rican children were more likely to have current asthma (ARR 1.46, 1.66, respectively) and to visit the ED/UCC (ARR 1.61, 1.67, respectively) than non-Hispanic whites. American Indian/Alaskan Native children were more likely to have current asthma (ARR 1.76) than non-Hispanic whites. Mexican/Mexican American children and adults had lower prevalence of current asthma but higher ED/UCC use (adults only) than non-Hispanic whites. Among adults, Puerto Ricans and American Indian/Alaskan Natives were more likely to have current asthma (ARR 1.60, 1.39, respectively) than non-Hispanic whites, and all the studied racial/ethnic groups except Asians were more likely to have visited the ED/UCC than non-Hispanic whites. Adults and children who received emergency care for asthma in the past 12 months more frequently received multiple components of asthma management and control (e.g., taking long-term medication, having an asthma management plan) compared to those without emergency care. Conclusions. Racial/ethnic differences in current asthma prevalence, asthma attacks, and increased utilization of emergency room visits for asthma among minorities persist among children and adults. Appropriate and effective asthma management and education may lead to better asthma control and reduce emergency care utilization.

Complementary and alternative medicine (CAM) use among children with current asthma.

OBJECTIVE To estimate the prevalence of complementary and alternative medicine (CAM) use among children with current asthma. DESIGN We analyzed data from the Asthma Call Back Survey (ACBS) 2006-2008. ACBS is a follow-up to the state-based Behavioral Risk Factor Surveillance System (BRFSS) survey that collects information on asthma and related factors including CAM use for asthma. The survey is administered to the parents who report in a subset of BRFSS states that their children have asthma. 5435 children had current asthma and were included in this analysis. RESULTS Overall, 26.7% (95% confidence interval [CI]=24.5-29.0) of children with current asthma reported CAM use in the previous 12 months. Among them, the three most commonly used therapies were breathing techniques (58.5%; 95% CI=53.6-63.5), vitamins (27.3%; 95% CI=23.0-31.5), and herbal products (12.8%; 95% CI=9.2-16.4). Multivariate analysis of CAM use revealed higher adjusted odds ratios (aOR) among children who experienced cost barriers to conventional health care compared with children with no cost barrier (aOR=1.8; 95% CI=1.2-2.8). Children with poorly controlled asthma were most likely to use all types of CAM when compared to their counterpart with well-controlled asthma: aOR=2.3 (95% CI=1.6-3.3) for any CAM; aOR=1.7 (95% CI=1.2-2.6) for self-care based CAM; and aOR=4.4 (95% CI=1.6-9.3) for practitioner-based CAM. CONCLUSIONS Children with poorly controlled asthma are more likely to use CAM; this likelihood persists after controlling for other factors (including parents education, barriers to conventional health care, and controller medication use). CAM is also more commonly used by children who experienced cost barriers to conventional asthma care. CAM use could be a marker to identify patients who need patient/family education and support thus facilitate improved asthma control.

Asthma prevalence among US elderly by age groups: age still matters.

Objective. For over three decades, the greatest burden of asthma deaths has occurred among persons aged 65 years and older. This study analyzed the association between increasing age and asthma prevalence among age groups within the US elderly population. Methods. We analyzed aggregated data on 54,485 civilian, noninstitutionalized US adults aged 65 years and older from the 2001–2010 National Health Interview Survey (NHIS). We estimated the prevalence of current asthma, lifetime asthma, and chronic obstructive pulmonary disease (COPD) among US elderly by 5-year age groups and age stages (“young elderly” aged 65–84 years and “oldest old” aged ≥85 years). We calculated adjusted odds ratios (AOR) and 95% confidence intervals (CI) to identify asthma prevalence patterns among elderly populations. Results. From 2001 to 2010, the estimated average annual prevalence of current asthma among US elderly was 7.0%. Estimates of lifetime asthma, COPD, and co-occurring current asthma and COPD were 9.9%, 9.7%, and 3.0%, respectively. Prevalence of asthma decreased with advancing age while prevalence of COPD increased with advancing age. When controlling for study variables and significant interactions (p = .05) with COPD, the odds of reporting current asthma decreased with advancing age: 0.87 (95% CI, 0.76–1.01) for 70- to 74-year-olds; 0.76 (95% CI, 0.66–0.87) for 75- to 79-year-olds; 0.62 (95% CI, 0.51–0.75) for 80- to 84-year-olds; and 0.45 (95% CI, 0.36–0.55) for ≥85-year-olds, as compared to 65- to 69-year-olds. Conclusions. Asthma continues to affect a substantial proportion of the US elderly population. Increased diagnosis of COPD may overshadow correct diagnosis and treatment in populations with advancing age. Treatment guidelines should focus on preventable risk behaviors to increase the quality of life within this population.

A Multisite Study of the Prevalence of HIV With Rapid Testing in Mental Health Settings

OBJECTIVES We estimated HIV prevalence and risk factors among persons receiving mental health treatment in Philadelphia, Pennsylvania, and Baltimore, Maryland, January 2009 to August 2011. METHODS We used a multisite, cross-sectional design stratified by clinical setting. We tested 1061 individuals for HIV in university-based inpatient psychiatric units (n = 287), intensive case-management programs (n = 273), and community mental health centers (n = 501). RESULTS Fifty-one individuals (4.8%) were HIV-infected. Confirmed positive HIV tests were 5.9% (95% confidence interval [CI] = 3.7%, 9.4%) for inpatient units, 5.1% (95% CI = 3.1%, 8.5%) for intensive case-management programs, and 4.0% (95% CI = 2.6%, 6.1%) for community mental health centers. Characteristics associated with HIV included Black race, homosexual or bisexual identity, and HCV infection. CONCLUSIONS HIV prevalence for individuals receiving mental health services was about 4 times as high as in the general population. We found a positive association between psychiatric symptom severity and HIV infection, indicating that engaging persons with mental illness in appropriate mental health treatment may be important to HIV prevention. These findings reinforce recommendations for routine HIV testing in all clinical settings to ensure that HIV-infected persons receiving mental health services are identified and referred to timely infectious disease care.

The Role of Income in Reducing Racial and Ethnic Disparities in Emergency Room and Urgent Care Center Visits for Asthma—United States, 2001–2009

Objective. To examine racial/ethnic disparities and associated factors in asthma-related emergency room (ER) and urgent care center (UCC) visits among US adults and determine whether disparities vary across increasing income strata. Methods. We analyzed data from 238,678 adult respondents from the 2001 to 2009 National Health Interview Survey and calculated the weighted annual prevalence of an ER/UCC visit for persons with current asthma. We used logistic regression to calculate adjusted odds ratios (AORs) for asthma-related ER/UCC visits by race/ethnicity and income, adjusting for demographics, socioeconomic, and other health-related factors. Results. The average annual prevalence of asthma-related ER/UCC visits among adults with current asthma was highest for Puerto Ricans (24.8%, 95% confidence interval [CI]: 20.3–29.9) followed by non-Hispanic American Indian/Alaskan Natives (22.1%, 95% CI: 14.4–32.4), non-Hispanic blacks (20.4%, 95% CI: 18.5–22.4), other Hispanics (17.3%, 95% CI: 15.0–19.9), Asians (11.0%, 95% CI: 7.8–15.4), and non-Hispanic whites (10.1%, 95% CI: 9.4–10.9). Puerto Ricans (AOR: 2.01; 95% CI: 1.54–2.62), non-Hispanic blacks (AOR: 1.72; 95% CI: 1.46–2.03), and other Hispanics (AOR: 1.55; 95% CI: 1.25–1.92) with current asthma had significantly higher odds of an asthma-related ER/UCC visit than non-Hispanic whites. Lower socioeconomic status, obesity, and serious psychological distress were also associated with higher odds of asthma-related ER/UCC visits. Puerto Ricans with the lowest income (AOR: 3.52; 95% CI: 2.27–5.47), non-Hispanic American Indian/Alaskan Natives with the highest income (AOR: 5.71; 95% CI: 1.48–22.13), and non-Hispanic blacks in every income stratum had significantly higher odds of asthma-related ER/UCC visits compared to non-Hispanic whites in the highest income stratum. Conclusions. Racial/ethnic disparities in asthma-related ER/UCC visits persist after accounting for income and other socioeconomic factors. Further research is needed to identify modifiable risk factors directly associated to race/ethnicity to decrease the asthma burden on minority populations.

Association Between Birthplace and Current Asthma: The Role of Environment and Acculturation

OBJECTIVES We evaluated associations between current asthma and birthplace among major racial/ethnic groups in the United States. METHODS We used multivariate logistic regression methods to analyze data on 102,524 children and adolescents and 255,156 adults in the National Health Interview Survey (2001-2009). RESULTS We found significantly higher prevalence (P < .05) of current asthma among children and adolescents (9.3% vs 5.1%) and adults (7.6% vs 4.7%) born in the 50 states and Washington, DC (US-born), than among those born elsewhere. These differences were among all age groups of non-Hispanic Whites, non-Hispanic Blacks, and Hispanics (excluding Puerto Ricans) and among Chinese adults. Non-US-born adults with 10 or more years of residency in the United States had higher odds of current asthma (odds ratio = 1.55; 95% confidence interval = 1.25, 1.93) than did those who arrived more recently. Findings suggested a similar trend among non-US-born children. CONCLUSIONS Current asthma status was positively associated with being born in the United States and with duration of residency in the United States. Among other contributing factors, changes in environment and acculturation may explain some of the differences in asthma prevalence.

Estimating the Number of Heterosexual Persons in the United States to Calculate National Rates of HIV Infection

Background This study estimated the proportions and numbers of heterosexuals in the United States (U.S.) to calculate rates of heterosexually acquired human immunodeficiency virus (HIV) infection. Quantifying the burden of disease can inform effective prevention planning and resource allocation. Methods Heterosexuals were defined as males and females who ever had sex with an opposite-sex partner and excluded those with other HIV risks: persons who ever injected drugs and males who ever had sex with another man. We conducted meta-analysis using data from 3 national probability surveys that measured lifetime (ever) sexual activity and injection drug use among persons aged 15 years and older to estimate the proportion of heterosexuals in the United States population. We then applied the proportion of heterosexual persons to census data to produce population size estimates. National HIV infection rates among heterosexuals were calculated using surveillance data (cases attributable to heterosexual contact) in the numerators and the heterosexual population size estimates in the denominators. Results Adult and adolescent heterosexuals comprised an estimated 86.7% (95% confidence interval: 84.1%-89.3%) of the U.S. population. The estimate for males was 84.1% (CI: 81.2%-86.9%) and for females was 89.4% (95% CI: 86.9%-91.8%). The HIV diagnosis rate for 2013 was 5.2 per 100,000 heterosexuals and the rate of persons living with diagnosed HIV infection in 2012was 104 per 100,000 heterosexuals aged 13 years or older. Rates of HIV infection were >20 times as high among black heterosexuals compared to white heterosexuals, indicating considerable disparity. Rates among heterosexual men demonstrated higher disparities than overall population rates for men. Conclusions The best available data must be used to guide decision-making for HIV prevention. HIV rates among heterosexuals in the U.S. are important additions to cost effectiveness and other data used to make critical decisions about resources for prevention of HIV infection.

Rapid HIV Testing at Gay Pride Events to Reach Previously Untested MSM: U.S., 2009-2010

We offered rapid HIV testing at social events frequented by young men who have sex with men (MSM), a group disproportionately affected by the HIV epidemic. We tested 1,312 MSM; of those MSM, 1,072 (81.7%) reported HIV testing history. Of those reporting HIV testing history, 550 (51.3%) were non-Hispanic black and 404 (37.7%) were aged <25 years. One hundred twenty-eight (11.9%) had never tested for HIV; 77 (7.2%) were preliminarily positive, with 15 (19.5%) being first-time testers. Factors associated with no previous HIV test included young age (13–24 years) (adjusted odds ratio [AOR] = 3.5, 95% confidence interval [CI] 1.9, 6.5) and non-Hispanic black (AOR=3.2, 95% CI 1.6, 6.4) or Hispanic (AOR=2.8, 95% CI 1.2, 6.3) race/ethnicity. HIV testing at Gay Pride events reaches young, previously untested MSM. This venue-based HIV testing approach at nonclinical sociocultural events is an additional strategy for HIV prevention goals to increase the number of people aware of their HIV infection with subsequent linkage to HIV care.

Nonvolitional sex and HIV-related sexual risk behaviours among MSM in the United States.

Objective:We estimated the prevalence of lifetime nonvolitional sex (NVS) among MSM by demographic characteristics, and characterized its association with HIV-related sexual risk behaviours among MSM in the United States. Design:The National Survey of Family Growth (NSFG) is a nationally representative cross-sectional survey of the United States. Methods:NSFG data from recent cycles 2002, and 2006–2010 were weighted and analysed for men aged 18–44 years who reported ever having anal or oral intercourse with another male. Associations of lifetime NVS (forced sex by men or women) and age of first NVS experience (<18 vs. ≥18 years), with HIV-related sexual risk behaviour outcomes in the past 12 months (i.e. sex with two or more male sex partners; exchanged sex for money or drugs; sex with IDU; sex with HIV-positive person; sex with two or more female sex partners) were assessed using adjusted prevalence ratios (aPR). Results:An estimated 3 226 872 or 5.8% of men aged 18–44 years were identified as MSM with 24.6% of them reporting ever experiencing NVS. MSM reporting NVS at age 18 years or older were more likely to have had sex with an IDU [aPR = 4.40; 95% confidence interval (95% CI) 1.78–10.88] and exchanged sex for money or drugs (aPR = 2.52; 95% CI 1.17–5.43) in the past 12 months compared with those not reporting NVS. NVS for MSM less than 18 years of age was associated with exchanging sex for money or drugs. Conclusion:Effective interventions to raise awareness of NVS among MSM and to offer support for MSM who have experienced NVS are needed.
