Insights
Early exposure to artificial colorants and urban living significantly increase asthma risk in children. Maternal smoking and industrialized milk also contribute to childhood asthma development.
Area of Science:
- Pediatric Allergy and Immunology
- Environmental Health
- Epidemiology
Context:
- Asthma is a prevalent chronic respiratory disease in children.
- Identifying modifiable risk factors is crucial for prevention strategies.
- Previous research highlights various environmental and lifestyle influences on childhood asthma.
Purpose:
- To investigate the association between known risk factors and asthma in children aged 6-10 years.
- To quantify the magnitude of these risk factors in a specific pediatric population.
- To identify key environmental and early-life exposures contributing to childhood asthma.
Summary:
- A case-control study involving 58 asthmatic and 117 non-asthmatic children (6-10 years) identified significant asthma risk factors.
- Key risk factors included early ingestion of artificial colorants (OR=13.2), urban living (OR=7.74), and maternal smoking during pregnancy (OR=2.4).
- Other identified risks were wool contact, passive smoking, and industrialized milk feeding, while common allergens like egg and chocolate were not significant.
Impact:
- Findings underscore the critical role of environmental exposures and early-life diet in childhood asthma.
- Highlights the need for public health interventions targeting artificial colorant consumption and maternal smoking.
- Provides evidence for targeted asthma prevention programs in urban pediatric populations.
Objective:
To study the magnitude of risk factors known for asthma in 6-10 year-old children.
Material And Methods:
This is a case- and control-study with 6-10 year-old children; 58 were asthmatic and 117 were control, with a relation 2:1. Asthmatic patients were recruited from consult of immuno-allergies department and control patients, from familial medicine consult of Hospital de Especialidades 71, IMSS. Indirect (mother) and directed surveys were applied, they were of multiple option for exploring the most known in literature-risk factors. Statistical management was performed by odds ratio with confidence interval of 95%.
Results:
The following variables were considered risk factors: ingestion of artificial colorants before having 1 year old (OR = 13.2), living in an urban area (OR = 7.74), maternal smoking during pregnancy (OR = 2.4), wool contact before having 1 year old (OR = 2.11), passive smoking exposure during pregnancy (OR = 1.486) and feeding with industrialized milk (OR = 1.2).
Conclusions:
Environmental risk factors are very important in our population, as well as early ablactation; however, ingestion before having 1 year old of allergens as egg, chocolate, orange and mango was not considered risk factor.
