Long-term effects on health of air pollution in children
Insights
Childhood respiratory diseases are influenced by factors like early infections, passive smoking, and air pollution. Understanding these risks is key to prevention and management of Chronic Non-Specific Respiratory Diseases (CNSRD).
Area of Science:
- Pediatrics
- Environmental Health
- Epidemiology
Background:
- Chronic Non-Specific Respiratory Diseases (CNSRD) pose a significant health burden in children.
- Identifying endogenous and exogenous factors is crucial for understanding disease development.
Purpose of the Study:
- To review and analyze the role of various factors in the development of pediatric CNSRD.
- To determine the relative importance of predisposing, provoking, and facilitating factors.
Main Methods:
- Literature review synthesizing existing research.
- Analysis of original clinical studies.
- Longitudinal epidemiological study involving 12,708 children, with a cohort of 1,303 followed over time.
Main Results:
- History of obstructive bronchitis in infancy and frequent early childhood respiratory infections are significant risk factors.
- Passive tobacco smoking, parental education, and early childhood care attendance impact disease development.
- Living in areas with high air pollution levels is strongly associated with increased respiratory symptoms.
Conclusions:
- Multiple factors, including early life exposures and environmental conditions, contribute to pediatric CNSRD.
- Interventions targeting passive smoking, air pollution, and socioeconomic factors may reduce disease incidence.
- Further research into the interplay of these factors is warranted for effective prevention strategies.
Abstract:
A literature review is presented showing the role and relative importance of various endogenous and exogenous factors, classified into predisposing, provoking and facilitating factors, in the development of Chronic Non-Specific Respiratory Diseases (CNSRD) in children. The review is also based on the results of own clinical studies and a longitudinal epidemiological study. In total, 12,708 children were examined in the epidemiological study, including a cohort of 1,303 children examined three times. In the analysis of the frequency and the dynamics of respiratory symptoms, significant contribution of various factors was demonstrated, including history of obstructive bronchitis in the first year of life, frequency of respiratory infections in early childhood, passive tobacco smoking, socioeconomic conditions such as education of parents, day nursery and kindergarten attendance and living in an area with high levels of air pollution.
