Neurotic illness in the families of children with asthma and wheezy bronchitis: a general practice population study

Systematic Review and Meta-Analysis of Anxious and Depressive Symptoms in Caregivers of Children With Asthma

OBJECTIVE

To provide a review of the literature comparing anxious and depressive symptoms in caregivers of children with asthma with caregivers of healthy children.

METHOD

A systematic search identified 25 studies from 17 articles, reporting outcomes on 4,300 caregivers of children with asthma and 25,064 caregivers of healthy children.

RESULTS

Overall, anxious (d = 0.50) and depressive symptoms (d = 0.44) were higher in caregivers of children with asthma compared with caregivers of healthy children. Age, site of recruitment, and whether the asthma diagnosis was medically confirmed were included as potential moderators. The relationship between parental psychopathology and asthma was stronger in those with medically confirmed asthma and participants recruited from clinical settings. Other moderators were not significant.

CONCLUSIONS

Caregivers of children with asthma appear to have greater anxious and depressive symptoms than caregivers of healthy children, but the reasons are unclear. More research that investigates modifiable factors that may moderate this association is urgently needed.

Depression among caregivers of children with asthma and its impact on communication with health care providers

BACKGROUND

Caregiver depression is common, can negatively influence one's ability to communicate with health care providers, and may hinder appropriate care for children with asthma.

OBJECTIVE

To evaluate the impact of caregiver depression on communication and self-efficacy in interactions about asthma with their child's physician.

STUDY DESIGN

Cross sectional analysis using data from the Prompting Asthma Intervention in Rochester-Uniting Parents and Providers study.

METHODS

We enrolled caregivers of children (2-12 yrs) with persistent asthma prior to their health care visit. Caregivers were interviewed via telephone after the visit to assess depression, self-efficacy, and provider communication at the visit. Caregiver depression was measured using the Kessler Psychological Distress scale. We assessed caregiver self-efficacy using items from the Perceived Efficacy in Patient-Physician Interactions scale; caregivers rated their confidence for each item (range 0-10). We also inquired about how well the provider communicated regarding the child's asthma care. Bivariate and multivariate analyses were used.

RESULTS

We interviewed 195 caregivers (response rate 78%; 41% Black, 37% Hispanic), and 30% had depressive symptoms. Caregiver rating of provider communication did not differ by depression. Most caregivers reported high self-efficacy in their interactions with providers; however depressed caregivers had lower scores (8.7 vs. 9.4, p = .001) than non-depressed caregivers. Further, depressed caregivers were less likely to be satisfied with the visit (66% vs. 83%, p = .014), and to feel all of their needs were met (66% vs. 85%, p = .007). In multivariate analyses, depressed caregivers were >2× more likely to be unsatisfied with the visit and to have unmet needs compared to non-depressed caregivers.

CONCLUSIONS

Depressed caregivers of children with asthma report lower confidence in interactions with providers about asthma and are less likely to feel that their needs are met at a visit. Further study is needed to determine the best methods to communicate with and meet the needs of these caregivers.

High prevalence of depression amongst mothers of children with asthma

OBJECTIVE

To compare the prevalence of depression among mothers of children with asthma and mothers of children without asthma and to investigate the influence of severity and duration of childhood asthma on maternal depression.

METHOD

A cross-sectional study including 80 mothers of children with asthma and 160 mothers of children without asthma who attended the pediatric outpatient clinics of a teaching hospital in Southern Brazil. The main outcome measure was the presence of depression in these mothers, measured by the Beck Depression Inventory.

RESULTS

The prevalence of depression was higher among mothers of asthmatic children compared with mothers of non-asthmatic children (43.8% vs. 17.5%, p < 0.001), with an adjusted prevalence ratio of 2.74 (95% confidence interval [CI] 1.76-4.25). Mothers of children with persistent asthma had a higher prevalence of depression than mothers of children with intermittent asthma (62.8% vs. 21.6%, p < 0.001), with an adjusted prevalence ratio of 2.77 (95% CI: 1.46-5.27). No significant association was observed between duration of childhood asthma and maternal depression.

CONCLUSION

Mothers of children with asthma have a higher prevalence of depression than mothers of children without asthma. The severity but not duration of childhood asthma is associated with maternal depression.

A review of candidate pathways underlying the association between asthma and major depressive disorder

OBJECTIVE

To consider the mechanisms that may link asthma and major depressive disorder (MDD). Asthma and MDD co-occur at higher rates than expected, but whether this reflects shared underlying pathophysiological mechanisms is not known.

METHODS

A review of the epidemiological data linking asthma and MDD was conducted and the possible biological mechanisms that could account for the high rate of this comorbidity were reviewed.

RESULTS

MDD occurs in almost half of patients with asthma assessed in tertiary care centers. Dysregulation of the hypothalamic pituitary adrenal axis may predispose people to both MDD and asthma, and similar alterations in the immune, autonomic nervous, and other key systems are apparent and may contribute to this increased risk of co-occurrence.

CONCLUSIONS

High rates of MDD in asthma may result from the stress of chronic illness, the medications used to treat it, or a combination of the two. The high level of co-occurrence may also reflect dysregulation of certain stress-sensitive biological processes that contribute to the pathophysiology of both conditions.

Psychological factors in asthma

Asthma has long been considered a condition in which psychological factors have a role. As in many illnesses, psychological variables may affect outcome in asthma via their effects on treatment adherence and symptom reporting. Emerging evidence suggests that the relation between asthma and psychological factors may be more complex than that, however. Central cognitive processes may influence not only the interpretation of asthma symptoms but also the manifestation of measurable changes in immune and physiologic markers of asthma. Furthermore, asthma and major depressive disorder share several risk factors and have similar patterns of dysregulation in key biologic systems, including the neuroendocrine stress response, cytokines, and neuropeptides. Despite the evidence that depression is common in people with asthma and exerts a negative impact on outcome, few treatment studies have examined whether improving symptoms of depression do, in fact, result in better control of asthma symptoms or improved quality of life in patients with asthma.

Presence of atopy in first-degree relatives as a predictor of a female proband's depression: results from the Northern Finland 1966 Birth Cohort

BACKGROUND

Recent investigations suggest a common genetic rather than environmental cause to explain the association between IgE-mediated atopic allergies and depression.

OBJECTIVE

Taking into account psychosocial confounding factors, we investigated separately and at the epidemiologic level the effects of maternal, paternal, and sibling atopy on the cumulative incidence of a child's depression.

METHODS

We used an unselected, genetically homogenous, general population birth cohort of 12,058 live-born children in Finland. The 31-year prospective follow-up included questionnaire information on atopic disorders of the cohort members' parents and siblings. The probands' own atopic conditions were evaluated by means of skin prick tests, and information on lifetime depression diagnoses was gleaned from postal questionnaires and national hospital discharge registers. Potential confounders were mother's parity, father's social class, maternal smoking during pregnancy, proband's regular daily smoking, and proband's dwelling place. Total variable information was available from 4068 cohort members.

RESULTS

Among female probands, the presence of atopy in parents was the strongest predictor for lifetime depression (P <.001), and sibling atopy and parental atopy were the strongest predictors for hospital-treated depression (P =.018 and P =.036, respectively). After controlling for confounders, it was noticed that maternal atopy increased a female proband's risk of lifetime depression up to 1.9-fold (odds ratio, 1.9; 95% CI, 1.1-3.0). The corresponding risk increased over 4-fold if parental-maternal atopy was combined with proband's own atopy.

CONCLUSIONS

Our findings suggest that maternal inheritance could be a significant causative factor in the association between atopy and depression of female probands.

Association between skin test diagnosed atopy and professionally diagnosed depression: a Northern Finland 1966 Birth Cohort study

BACKGROUND

Several studies have suggested an association between IgE-mediated atopic allergies and depression, although thus far no epidemiologic evidence involving a large, unselected, general-population sample and valid methods in diagnosing atopy support this putative association.

METHODS

We used the Northern Finland 1966 Birth Cohort, which was followed prospectively to age 31. Of the total cohort, 5428 individuals underwent skin tests for three of the most common allergens (i.e., cat, birch, and timothy grass) and for dust mites (Dermatophagoides pteronyssinus). Data on doctor-diagnosed lifetime depression were obtained from questionnaires.

RESULTS

After adjusting for social class, mothers' parity, place of residence, and psychiatric morbidity, the logistic regression analysis showed that the risk of developing depression when compared with nonatopic subjects increased up to 1.8-fold in atopic women (adjusted odds ratio 1.8, 95% confidence interval [CI] 1.2-2.6) and, when compared with skin-test-negative female subjects without allergic symptoms, reached 2.7-fold increases (95% CI 1.6-4.6) in those suffering from clinically manifest atopic disorders. Corresponding associations were not found among male subjects.

CONCLUSIONS

Our results indicate that women suffering from atopic diseases may possess an elevated risk for developing depression during early adulthood. Possible background theories (i.e., genetic abnormalities in serotonin metabolism, hypothalamic-pituitary-adrenal axis dysfunction, and histamine theory) are discussed.

Depression and asthma in children

Genetic vulnerability, allergic sensitivity, immunological compromise, and psychological stressors all contribute to the onset and severity of asthma. When depression decreases compliance and worsens prognosis, caring for an asthmatic child becomes even more problematic. Early intervention to address comorbid depressive disorders increases compliance, improves outcome, and allows a child to continue to appropriately to meet developmental expectations. In cases of severe asthma, treatment of depression may also decrease mortality.

Chronic fatigue syndrome in psychiatric patients: lifetime and premorbid personal history of physical health

OBJECTIVE

This preliminary report compares a group of chronic fatigue syndrome (CFS) patients and controls on several variables of potential significance in the etiology of CFS.

METHOD

The lifetime prevalence of reported physical disorders was compared among 46 CFS psychiatric patients, 92 relatively physically healthy psychiatric patients (C-I), and 46 psychiatric patients selected without regard to physical health (C-II). All patients were matched on age, sex, and psychiatric diagnosis and were drawn from the same psychiatric practice. The same groups were compared on a 7-point scale of lifetime physical health by three raters independently evaluating physical health narratives of the CFS patients up to the time of onset of CFS and that of the controls up to the corresponding age.

RESULTS

The CFS patients had a significantly higher reported lifetime prevalence of irritable bowel syndrome (IBS), infectious mononucleosis-like syndromes (IM), infectious mononucleosis-like syndromes two or more times (IM x 2), and herpes (other than genital or perioral herpes) than one or both control groups. The CFS group also had a higher incidence of allergic rhinitis or asthma, IBS, IM, and IM x 2 than the combined controls. On the independent ratings, the CFS patients had significantly more impaired physical health up to the time of onset of the CFS than C-I at a comparable age.

CONCLUSIONS

The findings suggest that a general health factor may be involved in the pathogenesis of some cases of CFS.

Psychiatric family history in adolescents with severe asthma

OBJECTIVE

To examine the hypothesis that an association exists between severe asthma and familial affective and anxiety disorders.

METHOD

A parent, usually the mother, of 62 adolescents admitted to a tertiary care asthma center was administered the Family History-Research Diagnostic Criteria Interview. Lifetime prevalence rates of psychiatric disorders in first-degree relatives were compared with previously reported rates.

RESULTS

In relatives of asthmatic adolescents, rates for depression, mania (females only), substance abuse (males only), and antisocial personality disorder were significantly higher than the rates in the non-ill comparison sample. Rates for substance abuse (males only) and antisocial personality disorder were higher than the rates for relatives of the depressed comparison sample. Rates for anxiety disorders were not higher than rates in epidemiological samples. Rates of attention-deficit hyperactivity disorder (females only) and posttraumatic stress disorder in relatives were higher than in community samples.

CONCLUSIONS

These results support the presence of a link between severe asthma and familial affective disorders, posttraumatic stress disorder, antisocial personality disorder, and substance abuse. Whether these disorders are genetically associated with asthma or represent an association with severe asthma because of environmental effects on the growing child is discussed.

Parental pressure for tonsillectomy: attitudes and knowledge of parents accompanying their children to an ear, nose and throat clinic

The parents of 120 children referred for possible tonsillectomy to an ear, nose and throat (ENT) surgeon were studied. There was no evidence that a desire for the operation fulfilled 'psychological needs' for parents or was a means of coping with a 'deviant' child. Parents favouring tonsillectomy were less well informed, and the educational role of the general practitioner in reducing the small number of those who inappropriately pressurize medical services is highlighted.

The effectiveness of attached social workers in the management of depressed female patients in general practice

There is a pressing need to evaluate the different forms of treatment for depressive illness encountered in general practice. This study consists of a controlled, randomized, clinical trial designed to investigate the effectiveness of social work intervention with depressed women. Eighty women aged between 18 and 45 were included and assessed initially by means of a psychiatric and social interview. Those ascertained to be suffering from 'acute' or 'acute on chronic' depression were randomly allocated to an experimental group who were referred to a social worker attached to a general practice or to a control group for routine treatment by their doctor. They were re-assessed 6 months later. Over 60% of both groups were clinically improved at follow-up, with no statistically significant differences between the two groups in clinical, social or medical outcome. Further analyses suggested, however, that those women initially assessed as suffering from 'acute on chronic' depression with major marital difficulties were found to benefit from social work treatment. These patients could be distinguished from the others by their high degree of motivation, by the initial severity of their problems and by the amount of practical help provided by the social workers.

Morbidity and school absence caused by asthma and wheezing illness

A survey in the London Borough of Croydon was conducted among an entire school cohort, aged about 9 years, to describe the current morbidity from wheezing illness, its relation to social and family factors, and its effects on social and educational development. A postal screening questionnaire was sent to 5100 parents, and 11.1% of the children were reported to have had wheezing illness over the previous 12 months. A sample of 284 parents were subsequently interviewed at home about their child's illness. School absence over the past year caused by wheezing illness was reported by 58%; and in 12% of children this amounted to more than 30 school days. School absence was strongly associated with all other indicators of morbidity-- short and long term. The proportion described as having "asthma' rose from 22% in those with no absence, to 50% in those with more than 30 days absence. Compared with 92 randomly selected controls with no history of wheezing, wheezy children had more atopic conditions, recurrent headaches, and abdominal pains. School absence was associated with parental separation, non-manual occupation of the mother, more than three children in the household, poor maternal mental health, lack of access to a car, and renting of accommodation. The child's illness had substantial effects on the activities of the mother and the rest of the family, but not on the child's social and recreational activities. Children with over 6 weeks' school absence scored appreciably worse on a teacher's assessment of their social, psychological, and educational adjustment.

Concordance of atopic and affective disorders

The personal and family history of bronchial asthma and/or hay fever was obtained from a series of 82 psychiatric patients. We report a significantly higher incidence of atopic disorders in affective patients (16/48) than in schizophrenic patients (2/34) (chi-square = 8.754, P less than 0.005). There was also a significantly higher incidence of atopic disorders among the first-degree relatives of patients with affective disorders (48/356) than among the first-degree relatives of patients with schizophrenia (10/182) (chi-square 8.501, P less than 0.005).
