Poor respiratory health outcomes associated with high illness worry and alexithymia: Eleven-year prospective cohort study among the working-age population.

OBJECTIVE: Poor respiratory health outcomes have been associated with poorer physical health and higher psychological distress. The aim of this study was to investigate whether illness worry, alexithymia or low sense of coherence predict i) the onset of new respiratory disease, ii) respiratory symptoms or iii) lung function among the working-age population, independently of comorbidity mood-, anxiety, or alcohol abuse disorders. METHODS: The study was conducted among a nationally representative sample of the Finnish population (BRIF8901) aged 30-54 years (N = 2310) in 2000-2001 and was followed up in 2011. Individuals with a diagnosed respiratory disease or a severe psychiatric disorder at baseline were excluded. Lung function was measured by a spirometry test and psychiatric disorders were diagnosed using a structured clinical interview. Structured questionnaires were used to measure self-reported respiratory symptoms and diseases, illness worry, alexithymia, and sense of coherence. RESULTS: High illness worry predicted an 11-year incidence of asthma (OR 1.47, 95% CI 1.09-1.99, p = 0.01). Alexithymia predicted shortness of breath (OR 1.32, 95% CI 1.13-1.53, p < 0.01) and 11-year incidence of COPD (OR 2.84, 95% CI 1.37-5.88, p < 0.01), even after several adjustments for physical and mental health. Psychological dispositions did not associate with lung function in 2011. CONCLUSIONS: In the general population, psychological factors that modify health behaviour predicted adverse respiratory health outcomes independently of lung function after 11 years of follow-up. This indicates that considering them part of personalized treatment planning is important for promoting health-related behaviour among the working-age population.

The association of psychological factors and healthcare use with the discrepancy between subjective and objective respiratory-health complaints in the general population.

BACKGROUND: We examined the prevalence of self-perceived respiratory symptoms (SRS) in the absence of any objective findings of respiratory pathology, and the association of such prevalence with psychological factors and healthcare use in the general population. METHODS: The study was conducted among a nationally representative sample of Finnish adults (BRIF8901). Respiratory functioning was measured by a spirometry test. Structured questionnaires were used to measure SRS, physician visits and psychological factors of alexithymia, sense of coherence, illness worry and common mental disorders. Individuals with a diagnosed respiratory disease or a severe psychiatric disorder, determined in a diagnostic interview, were excluded, giving a sample comprising 4544 participants. RESULTS: Twenty-six per cent of the general population and 36% of those with no diagnosed severe psychiatric disorder or respiratory disease experienced SRS despite a normal spirometry result. Psychological factors were associated with SRS (0.0001 < p < 0.032), and on the number of physician visit explaining 42.7% of the difference in visits between individuals with and without SRS, respectively. Illness worry was associated most strongly with SRS [odds ratio (OR) 1.29, 95% confidence interval (CI) 1.19-1.41, p < 0.0001] and higher numbers of physician visits (OR 1.35, CI 1.32-1.38, p < 0.00001), even after several adjustments. CONCLUSIONS: Respiratory symptoms without objective findings are common in the general population. The study results underline the role of psychological factors in the reporting of respiratory symptoms and the associated medical burden, thereby indicating the functional nature of the symptomatology.

Association between all-cause and cause-specific mortality and the GOLD stages 1-4: A 30-year follow-up among Finnish adults.

BACKGROUND: Mortality correlates with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria of airway obstruction. Yet, little data exist concerning the long-term survival of patients presenting with different levels of obstruction. METHODS: We studied the association between all-cause and cause-specific mortality and GOLD stages 1-4 in a 30-year follow-up among 6636 Finnish men and women aged 30 or older participating in the Mini-Finland Health Study between 1978 and 1980. RESULTS: After adjusting for age, sex, and smoking history, the GOLD stage of the subject showed a strong direct relationship with all-cause mortality, mortality from cardiovascular and respiratory diseases, and cancer. The adjusted hazard ratios of death were 1.27 (95% confidence interval (CI) 1.06-1.51), 1.40 (1.21-1.63), 1.55 (1.21-1.97) and 2.85 (1.65-4.94) for GOLD stages 1-4, respectively, with FEV1/FVC ≥70% as the reference. The association between GOLD stages 2-4 and mortality was strongest among subjects under 50 years of age at the baseline measurement. Cardiovascular mortality increased consistently for all GOLD stages. CONCLUSIONS: Airway obstruction indicates an increased risk for all-cause mortality according to the severity of the GOLD stage. We found that even stage 1 carries a risk for cardiovascular death independently of smoking history and other known risk factors.

Lung function and respiratory diseases in people with psychosis: population-based study.

BACKGROUND: There is little information on lung function and respiratory diseases in people with psychosis. AIMS: To compare the respiratory health of people with psychosis with that of the general population. METHOD: In a nationally representative sample of 8028 adult Finns, lung function was measured by spirometry. Information on respiratory diseases and symptoms was collected. Smoking was quantified with serum cotinine levels. Psychotic disorders were diagnosed utilising the Structured Clinical Interview for DSM-IV (SCID-I) and medical records. RESULTS: Participants with schizophrenia and other non-affective psychoses had significantly lower lung function values compared with the general population, and the association remained significant for schizophrenia after adjustment for smoking and other potential confounders. Schizophrenia was associated with increased odds of pneumonia (odds ratio (OR) = 4.9), chronic obstructive pulmonary disease (COPD, OR = 4.2) and chronic bronchitis (OR = 3.8); and with high cotinine levels. CONCLUSIONS: Schizophrenia is associated with impaired lung function and increased risk for pneumonia, COPD and chronic bronchitis.

Low socioeconomic status is associated with chronic obstructive airway diseases.

BACKGROUND: Worldwide, asthma and COPD are common causes of disability or death. Few studies have been made concerning the association with socioeconomic status (SES) and these diseases. PURPOSE AND METHODS: The aim of this nationwide population-based study was to determine the association with educational and income levels (SES) and chronic airway diseases (CAD), i.e., asthma or COPD (FEV1/FVC < 0.70). Univariate and multivariate logistic regression were used to estimate odds ratios in relation to education and household income, using age, gender, smoking in lifetime and body mass index as possible confounders. RESULTS: In this population-based cohort aged ≥30 years the prevalence of asthma was 9% (588/6525). COPD was observed in 5% (338/6525) of research subjects. In the multivariate logistic regression analysis when adjusted for gender, age, smoking history and BMI, the basic educational level remained an independent risk factor for COPD (OR 1.8, 95% CI 1.2-2.6) and the low household income for asthma (OR 1.4, 95% CI 1.0-1.9). CONCLUSIONS: In this large survey low SES measured by educational and income levels are risk factors of asthma and COPD.

COPD, chronic bronchitis and capacity for day-to-day activities: negative impact of illness on the health-related quality of life.

The aim of this study was to investigate the negative impact of illness on health-related quality of life (HRQoL) of people with chronic obstructive pulmonary disease (COPD) or chronic bronchitis. The study population consisted of the participants (N = 8028) of a health examination survey conducted in Finland. The sample in the present substudy was composed of 4718 participants who had complete information about spirometry. Variables age, gender, body mass index (BMI), illnesses, smoking in lifetime, education, FEV1% and incomes were entered in blockwise bivariate regression analysis to examine the relationships between capability for day-to-day activities (physical, psychological and social functioning) of those with COPD. Also, COPD (n = 277) and chronic bronchitis (n = 630) were compared with the general population (n = 3817). Study results showed that women with COPD had worse HRQoL than men, regarding the activities in daily living (ADL; odds ratio [OR] 2.63, 95% confidence interval [Cl] 1.15-5.99), instrumental activities of daily living (IADL; OR 4.23, 95% Cl 1.92-9.29) and exercise (OR 2.66, 95% Cl 1.21-5.84). Compared with the general population, people with chronic bronchitis were associated with poor ADL, IADL and exercise, (OR 1.58, 95% Cl 1.32- 1.92). Those with COPD, had difficulties managing in ADL (OR 4.02, 95% Cl 2.98-5.44), IADL (OR 3.27, 95% Cl 2.43-4.39), exercise (OR 3.35, 95% Cl 2.47 to 4.53). In this representative population-based sample, COPD and chronic bronchitis mean a significantly poor capability in physical functioning. People with chronic bronchitis experienced their daily life to be worse compared with the general population. Reductions in physical functioning for women and especially with COPD were also noteworthy.

Family dynamics in families of severe COPD patients.

AIM AND OBJECTIVES: The purpose of this study was to describe family dynamics in families with severe chronic obstructive pulmonary disease (COPD) on the basis of Barnhill's framework for healthy family systems. The sample consisted of 35 severe COPD patients and 30 family members at Tampere University Hospital, Finland or in the neighbouring regions. BACKGROUND: Chronic obstructive pulmonary disease is a public health problem worldwide. It is a slowly progressive airway disease, producing a decline in lung function which is not fully reversible. DESIGN: The sample included the families of patients without oxygen therapy and the families of patients who had long-term oxygen therapy (LTOT). The data were collected using the Family Dynamics Measure 2 (FDM2) and the Family Dynamics Questionnaire (FDQ). METHOD: A quantitative research method was employed in the study. Frequency and percentage distributions, as well as cross-tabulations, were used to describe the data. Mean values and standard deviations were calculated for the sum variables of six dimensions of the FDM2. RESULTS: In the dimensions of individuation, mutuality and flexibility, dynamics in the families of patients with LTOT was significantly better than of the patients without oxygen therapy. Especially in the dimension of mutuality, the families of LTOT patients functioned very well, while in the dimensions of communication and roles, family dynamics in these families was notably worse, although still good. CONCLUSION: Poor self-identity--enmeshment, isolation from others and lack of flexibility to varying conditions--in families with severe COPD can weaken the ability of the families to manage in everyday life. RELEVANCE TO CLINICAL PRACTICE: Families need family nursing to adapt to alterations occurring when a family member has severe COPD. Nurses can give support and help for these families for their roles of patient and caregiver, as well as opportunities to speak with someone about their situation.

Severe chronic obstructive pulmonary disease in a family's everyday life in Finland: perceptions of people with chronic obstructive pulmonary disease and their spouses.

The aim of this study is to describe the experiences of people with severe chronic obstructive pulmonary disease (COPD) in their everyday lives by using the World Health Organization's International Classification of Functioning, Disability, and Health. Five people with COPD and four spouses participated in the study. The data were collected by thematic personal interviews and were analyzed by deductive content analysis. The findings describe the impairment of body function of people with COPD, they provide knowledge of those factors that promote the well-being of people with COPD, how they cope on a daily basis, and the importance of their spouse. Knowledge about COPD for all health-care professionals is a precondition to ensure that people receive the help they need. People with COPD found it important to have a care relationship with their own treatment unit. The findings of the present study showed that peer support was an important matter.

Impact of chronic obstructive pulmonary disease on family functioning.

PURPOSE: The purpose of this study was to ascertain family dynamics of Finnish patients with severe chronic obstructive pulmonary disease (COPD) on the basis of Barnhill's framework for healthy family functioning. DESIGN AND METHOD: This study used description and comparison and an interview-administered questionnaire and survey. SAMPLE: Participants were patients with COPD and their family members (n = 65) living in the Tampere University Hospital catchment area. The sample consisted of families of home oxygen therapy patients (n = 36) and families of inpatients (n = 29). Families consisted of patients and their family members. INSTRUMENTS: Data were collected from patients by interview-administered questionnaires and from family members by survey. The instrument used was the Family Dynamics Measure 2, operationalized and tested by the American Family Research Group. RESULTS: Families of home oxygen therapy patients experienced significantly more mutuality (P =.03) and made decisions about their illness and life significantly more independently (P =.05) than families of inpatients. Families of home oxygen therapy patients handled change significantly more flexibly (P =.03) than families of inpatients. DISCUSSION: For the most part, families of both patient groups functioned well, but overall family functioning was clearly better in families of home oxygen therapy patients. The sample included some dysfunctional and even severely dysfunctional families. The results of this study cannot be generalized beyond the study sample because of the small sample size, but they provide suggestions for developing the care of patients with COPD and their families.
