Psychosocial influences on upper respiratory infectious illness in children
1St. George's Hospital Medical School, University of London, UK.
Insights
Psychological coping and social support influence children's susceptibility to infections. Stressful life events and daily hassles impact illness occurrence and duration, highlighting the importance of psychosocial factors in pediatric health.
Area of Science:
- Psychology
- Epidemiology
- Pediatrics
Background:
- Childhood stress is linked to illness, but the interplay of psychosocial factors requires further investigation.
- Understanding moderators of stress-induced vulnerability in children is crucial for public health.
- Previous research has not fully elucidated the combined effects of life events, social support, and coping styles on pediatric infectious illness.
Purpose of the Study:
- To examine the relationship between psychosocial factors and upper respiratory infectious illness in children.
- To investigate how life events, social support, and psychological coping influence the occurrence and duration of infections.
- To determine if daily hassles and coping strategies predict illness onset and symptom duration.
Main Methods:
- A 15-week longitudinal study involving 116 children aged 5-16 years.
- Assessment of life events, social support, psychological coping, daily hassles, and mood.
- Daily recording of upper respiratory symptoms, with clinical verification of infections.
Main Results:
- Life events and social support interacted to predict infection occurrence.
- Hassles interacted with avoidant coping to predict infection occurrence, independent of other factors.
- Problem-focused coping reduced infection duration, while avoidant coping increased it.
- Elevated hassle levels preceded symptom onset by three weeks.
Conclusions:
- Psychosocial factors, including coping strategies and social resources, significantly moderate children's vulnerability to infectious illness.
- Different psychosocial elements influence both the likelihood and the duration of pediatric infections.
- Targeting coping mechanisms and social support may be key interventions for reducing illness burden in children.
Abstract:
Fifty-five boys and 61 girls, aged 5-16 years, took part in a 15-week longitudinal study of stress and upper respiratory infectious illness. Life events, social support, and psychological coping were measured, and hassles and mood were assessed repeatedly throughout the study period. Upper respiratory symptoms were recorded daily, and episodes of upper respiratory infection were verified by clinical examination. Forty-eight verified episodes of infection were recorded from 41 participants (35.3% of the total sample). Life events and social support interacted in predicting the occurrence of infection, whereas hassles interacted with avoidant psychological coping, independently of age, gender, family composition, social class, negative affect, parental perceived stress, parental smoking, or alcohol consumption. The duration of symptomatic episodes was negatively associated with problem-focused coping, and positively related to avoidant coping. Hassle levels were elevated 3 weeks prior to symptom onset. These results indicate that the impact of life stress on vulnerability to infectious illness in children is moderated by psychological coping and social resources, and that different psychosocial factors influence the occurrence and duration of infections.
