Psychosocial factors and asthma in a community sample of older adults

Health and financial costs of adverse childhood experiences in 28 European countries: a systematic review and meta-analysis

BACKGROUND

Adverse childhood experiences (ACEs) are associated with increased health risks across the life course. We aimed to estimate the annual health and financial burden of ACEs for 28 European countries.

METHODS

In this systematic review and meta-analysis, we searched MEDLINE, CINAHL, PsycINFO, Applied Social Sciences Index and Abstracts, Criminal Justice Databases, and Education Resources Information Center for quantitative studies (published Jan 1, 1990, to Sept 8, 2020) that reported prevalence of ACEs and risks of health outcomes associated with ACEs. Pooled relative risks were calculated for associations between ACEs and harmful alcohol use, smoking, illicit drug use, high body-mass index, depression, anxiety, interpersonal violence, cancer, type 2 diabetes, cardiovascular disease, stroke, and respiratory disease. Country-level ACE prevalence was calculated using available data. Country-level population attributable fractions (PAFs) due to ACEs were generated and applied to 2019 estimates of disability-adjusted life-years. Financial costs (US$ in 2019) were estimated using an adapted human capital approach.

FINDINGS

In most countries, interpersonal violence had the largest PAFs due to ACEs (range 14·7-53·5%), followed by harmful alcohol use (15·7-45·0%), illicit drug use (15·2-44·9%), and anxiety (13·9%-44·8%). Harmful alcohol use, smoking, and cancer had the highest ACE-attributable costs in many countries. Total ACE-attributable costs ranged from $0·1 billion (Montenegro) to $129·4 billion (Germany) and were equivalent to between 1·1% (Sweden and Turkey) and 6·0% (Ukraine) of nations' gross domestic products.

INTERPRETATION

Availability of ACE data varies widely between countries and country-level estimates cannot be directly compared. However, findings suggest ACEs are associated with major health and financial costs across European countries. The cost of not investing to prevent ACEs must be recognised, particularly as countries look to recover from the COVID-19 pandemic, which interrupted services and education, and potentially increased risk factors for ACEs.

Depressive Symptoms and Overperception of Airflow Obstruction in Older Adults With Asthma

OBJECTIVE

Older adults are at increased risk for depression and poor asthma outcomes. We examined whether depressive symptoms are associated with overperception of airflow obstruction and a pattern of worse asthma control, but not pulmonary function.

METHODS

We recruited a cohort of adults with asthma 60 years and older in East Harlem and the Bronx, New York. Baseline measures included the Geriatric Depression Scale, Asthma Control Questionnaire, and Mini Asthma Quality of Life Questionnaire. Spirometry was conducted at baseline to assess pulmonary function. Perception of airflow obstruction was assessed for 6 weeks following baseline by participants entering estimates of peak expiratory flow (PEF) into a programmable peak flow meter followed by PEF blows. Participants were blinded to actual PEF values. The percentage of time that participants were in the overperception zone was calculated as an average.

RESULTS

Among the 334 participants (51% Hispanic, 25% Black), depressive symptoms were associated with overperception of airflow obstruction (β = 0.14, p = .029), worse self-reported asthma control (β = 0.17, p = .003), and lower asthma-related quality of life (β = -0.33, p < .001), but not with lung function (β = -0.01, p = .82). Overperception was also associated with worse self-reported asthma control (β = 0.14, p = .021), but not lung function (β = -0.05, p = .41).

CONCLUSIONS

Depressive symptoms were associated with greater perceived impairment from asthma, but not pulmonary function. Overperception of asthma symptoms may play a key role in the relationship between depression and asthma outcomes in older adults.

Asthma Across the Ages: Adults

Asthma is a common disease affecting approximately 300 million people worldwide, across all age ranges. Despite advances in asthma outcomes of the last few decades, there remains room for improvement in asthma management and for patient outcomes, particularly in older patients. The heterogeneity of asthma is now well recognized, and is known to complicate response to treatment and patient behavior and impact health outcomes. Asthma and its heterogeneity change according to age. Asthma affects people differently across the life span. In adults, prevalence is highest among those in middle age; however, mortality is greater in the older age group. In this clinical commentary, we describe how age impacts asthma prevalence and incidence, outcomes, disease expression, and approach to management in adulthood and in older patients.

Adverse childhood experiences and chronic lung diseases in adulthood: a systematic review and meta-analysis

Background: Adverse childhood experiences (ACE) affect physical and mental health and may appear as risk factors for the development of different conditions in adult life. Objective: To perform a literature review and meta-analysis on risk indicators for the development of chronic lung diseases in adulthood associated with ACE. Method: We conducted a systematic literature review according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using the online databases PubMed, PsycINFO, and Web of Science. Quantitative studies involving male and female adults were included. Fixed- and random-effect models were used in the estimation of meta-analytical measures. The heterogeneity between studies was assessed using I² statistics and Cochran's Q test. Results: A total of 19 studies were selected for the meta-analysis. The analyses showed statistically significant associations between ACE and lung diseases in general (OR = 1.41; CI 95%: 1.28-1.54), besides specific associations with asthma (OR = 1.32; CI 95%: 1.13-1.50) and COPD (OR = 1.44; CI 95%: 1.13-1.76). When the mediating effect of smoking was assessed separately we found a significant - although not quite expressive - association (OR = 1.06; CI 95%: 1.02 to 1.10), which weakens the hypothesis that a direct relationship exists between childhood trauma and the occurrence of lung diseases. Conclusions: ACE are an important risk factor for the development of lung diseases in adulthood, whether through direct or indirect contribution to this outcome, which highlights the relevance of increasing the awareness of health staff for the early detection and intervention in situations of vulnerability or risk in childhood as an important preventative measure.

Life course health consequences and associated annual costs of adverse childhood experiences across Europe and North America: a systematic review and meta-analysis

BACKGROUND

An increasing number of studies are identifying associations between adverse childhood experiences (ACEs) and ill health throughout the life course. We aimed to calculate the proportions of major risk factors for and causes of ill health that are attributable to one or multiple types of ACE and the associated financial costs.

METHODS

In this systematic review and meta-analysis, we searched for studies in which risk data in individuals with ACEs were compared with these data in those without ACEs. We searched six electronic databases (MEDLINE, CINAHL, PsycINFO, Applied Social Sciences Index and Abstracts, Criminal Justice Databases, and the Education Resources Information Center) for quantitative studies published between Jan 1, 1990, and July 11, 2018, that reported risks of health-related behaviours and causes of ill health in adults that were associated with cumulative measures of ACEs (ie, number of ACEs). We included studies in adults in populations that did not have a high risk of ACEs, that had sample sizes of at least 1000 people, and that provided ACE prevalence data. We calculated the pooled RR for risk factors (harmful alcohol use, illicit drug use, smoking, and obesity) and causes of ill health (cancer, diabetes, cardiovascular disease, respiratory disease, anxiety, and depression) associated with ACEs. RRs were used to estimate the population-attributable fractions (PAFs) of risk attributable to ACEs and the disability-adjusted life-years (DALYs) and financial costs associated with ACEs. This study was prospectively registered in PROSPERO (CRD42018090356).

FINDINGS

Of 4387 unique articles found following our initial search, after review of the titles (and abstracts, when the title was relevant), we assessed 880 (20%) full-text articles. We considered 221 (25%) full-text articles for inclusion, of which 23 (10%) articles met all selection criteria for our meta-analysis. We found a pooled prevalence of 23·5% of individuals (95% CI 18·7-28·5) with one ACE and 18·7% (14·7-23·2) with two or more ACEs in Europe (from ten studies) and of 23·4% of individuals (22·0-24·8) with one ACE and 35·0% (31·6-38·4) with two or more ACEs in north America (from nine studies). Illicit drug use had the highest PAFs associated with ACEs of all the risk factors assessed in both regions (34·1% in Europe; 41·1% in north America). In both regions, PAFs of causes of ill health were highest for mental illness outcomes: ACEs were attributed to about 30% of cases of anxiety and 40% of cases of depression in north America and more than a quarter of both conditions in Europe. Costs of cardiovascular disease attributable to ACEs were substantially higher than for most other causes of ill health because of higher DALYs for this condition. Total annual costs attributable to ACEs were estimated to be US$581 billion in Europe and $748 billion in north America. More than 75% of these costs arose in individuals with two or more ACEs.

INTERPRETATION

Millions of adults across Europe and north America live with a legacy of ACEs. Our findings suggest that a 10% reduction in ACE prevalence could equate to annual savings of 3 million DALYs or $105 billion. Programmes to prevent ACEs and moderate their effects are available. Rebalancing expenditure towards ensuring safe and nurturing childhoods would be economically beneficial and relieve pressures on health-care systems.

Are asthma patients at increased risk of clinical depression? A longitudinal cohort study

OBJECTIVE

In this study, we assessed whether adult patients with asthma are more likely to be diagnosed with depression than diabetes patients or "healthy" controls during follow-up in primary care.

METHODS

Data from the Nijmegen Continuous Morbidity Registration were used to assess the risk for a first depression. Patients with asthma were compared with patients with diabetes and with two healthy controls matched on age, gender, socioeconomic status and attending general practice. With Cox proportional hazard analysis, we compared the risk of depression between these groups. These analyses were corrected for relevant covariates including a time-depending variable for multimorbidity. Explorative subgroup analyses were done for age, gender, socioeconomic status and multimorbidity.

RESULTS

Cumulative incidence of depression in asthma patients was 5.2%, in DM patients 4.1% and in control subjects 3.3%. The hazard ratios for a first episode of depression in the asthma patients (n = 795) compared to DM patients (n = 1033) and control subjects after correction for covariates were 1.11 (95% CI 0.60-2.04) and 1.18 (95% CI 0.78-1.79), respectively. Exploratory analyses showed that asthma patients without multimorbidity were at higher risk for a depression compared to reference groups, while asthma patients with multimorbidity were at lower risk for depression.

CONCLUSION

Asthma patients were not more likely to be diagnosed with a first depression compared to "healthy" control subjects or diabetes patients. The influence of multimorbidity on depression risk in asthma patients warrants further study.

Coping and social support in asthma and allergy: the Västerbotten Environmental Health Study

OBJECTIVES

Asthma and allergy are stressful conditions that require coping strategies and social support to reduce stress and enhance health-promoting behavior. However, research is limited regarding coping and social support in asthma and allergy. The aim was to better understand the use of different coping strategies and perceived social support in low and high severity (exacerbation frequency) of asthma and allergy.

METHODS

Population-based data were used to provide ratings of coping strategies (Study I) and social support (Study II) from 124 and 94 participants, respectively, with asthma and/or allergy, categorized as low or high in severity. Problem- and emotion-focused coping strategies were assessed as well as emotional, instrumental and informative social support from seven sources.

RESULTS

Study I showed that avoiding certain environments (problem-based coping) and trying to accept one's situation (emotion-based) were the most commonly used coping strategies. These behaviors did not differ due to severity. Study II showed that more emotional than instrumental and informative support was perceived. The highest rated support sources were the partner, family members and the healthcare system. More social support was reported in low asthma/allergy severity compared to high asthma/allergy severity.

CONCLUSION

The most commonly used coping strategies in the population of persons with these four types of asthma and allergy are avoiding certain environments and trying to accept one's situation. More emotional support than instrumental and informative is perceived to be received, and most of the support is received from one's partner and other family members and least from authorities and patient associations/support groups.

Confidant Relations in Italy

Confidants are often described as the individuals with whom we choose to disclose personal, intimate matters. The presence of a confidant is associated with both mental and physical health benefits. In this study, 135 Italian adults responded to a structured questionnaire that asked if they had a confidant, and if so, to describe various features of the relationship. The vast majority of participants (91%) reported the presence of a confidant and regarded this relationship as personally important, high in mutuality and trust, and involving minimal lying. Confidants were significantly more likely to be of the opposite sex. Participants overall were significantly more likely to choose a spouse or other family member as their confidant, rather than someone outside of the family network. Familial confidants were generally seen as closer, and of greater value, than non-familial confidants. These findings are discussed within the context of Italian culture.

Psychiatric morbidity in chronic respiratory disorders in an Indian service using GMHAT/PC

OBJECTIVE

The study aimed to assess psychiatric morbidity in stable chronic respiratory disorders and to examine the pattern of psychiatric illness in specific respiratory disorders in Northern India.

METHODS

All consecutive patients with stable chronic respiratory illnesses who attended the respiratory disease clinic were recruited in the study. Their healthy attendants were interviewed as a control group. The research clinician, trained in the use of the Global Mental Health Assessment Tool, Primary Care Version (GMHAT/PC), interviewed all the participants. The respiratory consultant made the respiratory illness diagnosis. The data were analyzed comparing the patient and the control group by using relative risk and adjusted odds ratios.

RESULTS

Of 391 patients with respiratory illness, 44.8% had a mental illness identified by GMHAT/PC interview compared with 24.3% of 177 attendants (controls). Anxiety (20.6%), depression (13.2%) and obsessive compulsive disorders (4.6%) were the most frequently identified mental disorders in the respiratory disease group. Chronic obstructive pulmonary disease and bronchial asthma when combined with rhinitis had a significantly higher prevalence of comorbid mental illness than those illnesses alone.

CONCLUSION

Patients with chronic respiratory illness have high mental health comorbidity. Physicians and practitioners can be trained to identify mental illness using computer-assisted tools such as GMHAT/PC (which is easy to use by clinicians and well accepted by patients). A holistic approach of providing care to such patients may improve their overall outcome and quality of life.

Childhood adversities and adult-onset asthma: a cohort study

OBJECTIVES

Childhood adversities may be important determinants of later illnesses and poor health behaviour. However, large-scale prospective studies on the associations between childhood adversities and the onset of asthma in adulthood are lacking.

DESIGN

Prospective cohort study with 7-year follow-up.

SETTING

Nationally representative study. Data were collected from the Health and Social Support (HeSSup) survey and national registers.

PARTICIPANTS

The participants represent the Finnish population from the following age groups: 20-24, 30-34, 40-44, and 50-54 years at baseline in 1998 (24 057 survey participants formed the final cohort of this study). The occurrence of childhood adversities was assessed at baseline with a six-item survey scale. The analyses were adjusted for sociodemographic characteristics, behavioural health risks and common mental disorders.

PRIMARY AND SECONDARY OUTCOMES

The survey data were linked to data from national health registers on incident asthma during a 7-year follow-up to define new-onset asthma cases with verified diagnoses.

RESULTS

A total of 12 126 (59%) participants reported that they encountered a childhood adversity. Of them 3677 (18% of all) endured three to six adversities. During a follow-up of 7 years, 593 (2.9%) participants were diagnosed with incident asthma. Those who reported three or more childhood adversities had a 1.6-fold (95% CI 1.31 to 2.01) greater risk of asthma compared to those without childhood adversities. This hazard attenuated but remained statistically significant after adjustment for conventional risk factors (HR 1.33; 95% CI 1.06 to 1.67).

CONCLUSIONS

Adults who report having encountered adversities in childhood may have an increased risk of developing asthma.

Relationship between posttraumatic stress disorder and asthma among New York area residents exposed to the World Trade Center disaster

OBJECTIVE

The heightened prevalence rates of respiratory problems and posttraumatic stress disorder (PTSD) among New York area residents following the World Trade Center disaster on September 11, 2001, have received national attention. Although there is some evidence suggesting that PTSD is associated with increased risk for asthma, this relationship has not been well documented in this population at high risk for both disorders. There is also a need to examine this relationship while controlling for notable confounds, including dust exposure and smoking.

METHOD

This study examined the association between symptoms indicative of probable PTSD and the diagnosis of asthma following 9/11 among the individuals who participated in the World Trade Center Health Registry (WTCHR) baseline study between September 2003 and November 2004. A total of 71,437 participants enrolled in this study and completed questionnaires pertaining to exposure, physical health symptoms before and after 9/11, and self-reported PTSD symptoms.

RESULTS

Logistic regression revealed that, compared to participants without probable PTSD, individuals with probable PTSD were 1.65 times more likely to be diagnosed with asthma following 9/11, which was significant after controlling for the effects of gender, ethnicity, income, smoking status, dust exposure, and nonspecific psychological distress [Wald χ(2) (1)=52.375, P<.001].

CONCLUSION

These results suggest that PTSD symptoms are associated with the development of asthma following 9/11 and that this relationship is not explained by sociodemographic, environmental, and lifestyle factors.

Relationship between current psychological symptoms and future risk of asthma outcomes: a 12-month prospective cohort study

BACKGROUND

Subjects with asthma are more susceptible to psychological symptoms, but it is uncertain whether psychological symptoms are linked to future risk of asthma outcomes.

OBJECTIVE

To investigate the relationship between current psychological symptoms and future risk of asthma outcomes.

METHODS

We conducted a prospective cohort study with a 12-month follow-up period of 297 patients with asthma. Psychological symptoms, lung function, asthma control test, and Asthma Quality of Life Questionnaire at baseline were assessed. Asthma outcomes including exacerbations, unplanned visits, emergency visits, hospital admissions, intensive care unit admissions, and length of hospital stays were monitored monthly. The time to the first asthma outcomes was analyzed. Furthermore, the association between psychological symptoms and future risk of asthma outcomes was calculated as adjusted relative risk (RR) using logistic regression models.

RESULTS

The asthma patients were assigned to one of three groups: neither anxiety nor depression symptoms (NAD, n = 102), either anxiety or depression symptoms (A/D, n = 68), or anxiety and depression symptoms (AD, n = 120). Logistic regression models indicated that asthma patients in the AD group, but not the A/D group, had an increased adjusted RR for unplanned visits and emergency visits (RR = 2.33, 95% confidence interval (CI) = [1.50, 3.61]; and RR = 3.13, 95% CI = [1.90, 5.17], respectively). The time to the first asthma outcomes including exacerbations, unplanned visits, and emergency visits was shorter in patients with psychological symptoms than those without (all p < .001).

CONCLUSION

Current psychological symptoms, especially anxiety combined with depression, independently predict the future risk of asthma outcomes. Ting Zhou and Lan Wang contributed equally to this study.

Effect of age on asthma control: results from the National Asthma Survey

BACKGROUND

two million US citizens older than 65 years have asthma, but little is known about asthma control in this population.

OBJECTIVE

to compared short- and long-term asthma control in elderly (≥ 65 years old) and young adult (18-64 years old) populations from the National Asthma Survey.

METHODS

data from the National Asthma Survey (sponsored by the Centers for Disease Control and Prevention) were analyzed. Demographic variables, health insurance status, smoking status, indoor allergen exposure, and asthma education were compared between the young adult and elderly populations. Asthma control was examined based on short-term measures (recent oral corticosteroid bursts or symptoms) and long-term measures (asthma attacks, urgent care visits, hospitalizations, and activity limitation in the previous year).

RESULTS

a total of 2,557 young and 398 elderly asthmatic patients were included. Elderly patients had a lower income, were less educated, were more obese, were more insured, had less indoor exposure, and were more likely to be former smokers. They were less educated about asthma attack interventions and asthma action plans (P < .05 for both). On multivariate analysis, elderly patients had worse control of asthma based on short-term measures (daytime symptoms in the previous month [odds ratio (OR), 1.73; 95% confidence interval (CI), 1.25-2.35] and any short-term measure [OR, 1.48; 95% CI, 1.11-1.97]) and long-term measures (activity limitation in the previous year [OR, 1.50; 95% CI, 1.12-2.01]).

CONCLUSIONS

elderly asthmatic patients have worse short- and long-term asthma control compared with the young adult population. Further studies are needed to elucidate whether these findings are due to pathophysiologic differences and whether tailored education or other novel strategies can provide better asthma control.

Onset of depressive symptoms among adults with asthma: results from a longitudinal observational cohort

AIMS

Individuals with asthma may be at increased risk of depression, but few studies have identified precursors to the onset of depression. The study goal was to identify risk factors for depression onset among a community-based sample of adults with asthma.

METHODS

Data were obtained from three telephone interviews conducted at 2-yearly intervals on a longitudinal cohort of adults with asthma (n=439). The Center for Epidemiologic Studies Depression scale (CESD) was used to measure depressive symptoms. Multiple regression analyses tested associations of sociodemographic and health-related variables with depression prevalence (cross-sectional analyses) and incident depression (longitudinal analyses).

RESULTS

15% of subjects were classified as "depressed" (CESD> or =23) at each interview. Individuals depressed at baseline were more likely to drop out (OR=1.76 [95% CI 1.05, 2.96]). Low perceived control of asthma (measured with the Perceived Control of Asthma Questionnaire [PCAQ]) exhibited the most consistent association with depression. Lower PCAQ was cross-sectionally associated with depression (OR=0.51 per 0.5 SD difference in PCAQ [0.35, 0.75]). Onset of depression was noted in 38 individuals. Decrease in perceived control at follow-up was associated with depression onset (OR=7.47 [2.15, 26.01]).

CONCLUSIONS

Low perceived control of asthma predicted depression onset among adults with asthma. This risk factor may respond to self-management education.

Cancer in working-age is not associated with childhood adversities

BACKGROUND

Early life events are studied as potential causes of cancer. The objective here was to study childhood adversities in the etiology of cancer.

METHODS

The material comprised a population based random sample of 25 898 individuals among the Finnish working-aged population. In 1998 they were requested through six questions in a postal questionnaire to recall their childhood adversities. The cases consisted of people with cancer diagnosed 2000-2006 and registered in the Finnish Cancer Registry (n = 384). The rest of the sample consisted of cancer-free controls.

RESULTS

The most common adversities were prolonged financial difficulties, serious conflicts in the family and someone in the family having been seriously or chronically ill. The cancer patients reported more prolonged financial difficulties and someone seriously or chronically ill in the family. They reported less parental divorce than the controls. The associations were not statistically significant after adjusting for age, sex, education, and health behaviour. Nor was there a significant difference in the total number of childhood adversities between the study group and the controls.

CONCLUSION

On the whole, these cancer patients had not experienced more childhood adversities than the controls. According to our findings, there is no cause to attribute development of cancer in working age to childhood adversities. This information may also give relief to other family members.

Does insular stroke disrupt the self-medication effects of nicotine?

This paper explores the relationship between insular stroke and the disruption of tobacco use. A functional analysis of the role of the insula in maintaining homeostasis suggests that the insula monitors hypoxia and applies dyspnea to motivate the individual to regulate breathing. From its' early usage, nicotine has been used to treat respiratory disorders. It increases respiratory drive, promoting better breathing. Insular stroke likely interferes with this self-regulation. A new self-medication model is proposed for tobacco use. The effect on public policy is discussed.

The asthma/mental health nexus in a population-based sample of the United States

BACKGROUND

Asthma is one of the most prevalent chronic medical conditions in the United States. The relationship of asthma with psychological factors has been known for centuries, and recently there has been a resurgence of interest in this topic. This study investigates the relationship between current asthma and poor mental health in a nationally representative sample of the US population.

METHODS

This study utilizes data from the 2006 Behavioral Risk Factor Surveillance System survey (n = 355,710). A multinomial logistic regression model was constructed to assess the relationship between current asthma and poor mental health. The relationship between formerly having asthma and poor mental health was also investigated.

RESULTS

Persons reporting poor mental health have increased risk of currently having asthma compared to persons reporting good mental health. Additionally, this asthma/mental health relationship has a "dose-response" relationship. For every incremental increase in days of poor mental health, there is a corresponding increase in risk of currently having asthma. Previously reported risk factors for asthma (ie, age, gender, race, marital, smoking, overall health, exercise, obesity, and socioeconomic status) were all found to be important covariates of asthma. The relationship between former asthma and poor mental health is less clear.

CONCLUSIONS

This large, nationally representative sample confirms the relationship between asthma and mental health symptoms. Any degree of poor mental health appears to increase one's risk for asthma. Future research is needed to determine the causal and/or physiologic relationship between asthma and mental health symptoms.

Psychosocial predictors of physical activity in older aged asthmatics

BACKGROUND

there is little information available on physical activity (PA) patterns and the psychosocial determinants of PA in older adults with asthma.

OBJECTIVE

to quantify the prevalence of PA in older asthmatics and to explore the potential psychosocial determinants of PA in this population.

STUDY DESIGN AND SETTING

cross-sectional data available from the Canadian Community Health Survey (CCHS), cycle 2.1, were used. There was a total of 1,772 older asthmatics in the sample.

RESULTS

there were significant differences in the prevalence of PA between older asthmatic females compared to middle-aged asthmatic females (chi(2) = 23.65, P < 0.0001) and older asthmatics compared to older non-asthmatics (chi(2) = 38.1, P < 0.0001). Logistic regression revealed a significant association between PA and perceived health in older asthmatic males (OR = 5.39, CI = 1.36-21.33) and females (OR = 4.81, CI = 1.41-16.38). Being a member of a volunteer organisation was also significantly associated with PA in older asthmatic females (OR = 1.59, CI = 1.11-2.30).

CONCLUSION

older asthmatics were less active than their non-asthmatic peers. Perceived health was an important predictor of PA in both older asthmatic males and females. Exercise interventions in this population should make an effort to improve self-perceived health.

Psychosocial factors and incident asthma hospital admissions in the EPIC-Norfolk cohort study

BACKGROUND

Case series and case-control studies have shown high rates of psychosocial and behavioural risk factors amongst patients admitted to hospital with severe asthma. General population studies have shown associations between psychosocial factors and prevalent asthma but few have investigated incident asthma outcomes.

METHODS

Data on psychosocial factors and asthma hospital admissions were available for 20 854 participants, aged 41-80 years, in the Norfolk cohort of the European Prospective Investigation into Cancer study. Postal assessments included details of physical functioning, mood disorder history, social adversity and social support.

RESULTS

A total of 686 asthma hospital admissions were recorded. Psychosocial factors present at baseline, including current mood disorders, adverse circumstances in childhood, the impact of life events experienced during adulthood and negative perceived support from a close confidant, were associated with increased rates of hospital admission independent of age, sex, indicators of socio-economic status, physical functional health, and obesity. Restricted to those participants who reported lifetime doctor-diagnosed asthma at baseline, the reported impact of adverse life events experienced in adulthood, and both confiding and negative aspects of support quality, were associated with asthma hospital admission. The magnitude of these associations was comparable to those involving indicators of socio-economic status and physical health.

CONCLUSIONS

These results show that psychosocial factors are associated with incident asthma hospital admissions and highlight the potential importance of taking account of psychosocial factors, including availability and quality of support networks, in guiding long-term asthma management.
