MATERNAL STRESS AND ENVIRONMENTAL RISK FACTORS OF CHILDHOOD ASTHMA

Area of Science:

• Pediatrics
• Environmental Health
• Epidemiology

Background:

• Childhood asthma is a prevalent respiratory condition with significant global health implications.
• Environmental factors and maternal health during pregnancy are increasingly recognized as crucial in asthma development.
• Existing research suggests a potential link between maternal stress and fetal lung development, impacting asthma risk.

Purpose of the Study:

• To investigate the association between maternal psychological stress during pregnancy and the incidence of childhood asthma.
• To identify environmental factors and maternal risk factors that correlate with childhood asthma.
• To explore the intrauterine effects of maternal conditions on the development of asthma in children.

Main Methods:

• A case-controlled retrospective study involving 84 children aged 6-8 years, with 40 diagnosed with asthma.
• Maternal risk factors and environmental correlates were assessed using a questionnaire.
• Statistical analyses were performed to determine correlations between various factors and childhood asthma.

Main Results:

• Severe maternal stress during pregnancy showed a significant positive correlation with childhood asthma (r=.532; p=0.000).
• Other positive correlations included low birth weight (<2500g), maternal and paternal history of asthma, allergies, and chronic bronchitis, as well as lower parental education levels.
• Negative correlations were observed with full-term birth, breastfeeding, moderate maternal stress, working parents, and higher family income.

Conclusions:

• Intrauterine exposure to maternal factors, particularly severe psychological stress, significantly influences the development of childhood asthma.
• Maternal stress during pregnancy may act as a trigger for wheezing and asthma in offspring.
• The findings underscore the importance of maternal well-being during pregnancy for preventing childhood respiratory diseases like asthma.
