BACKGROUND: Several studies have been done to evaluate the relationship between month of birth and atopic diseases but the results are contradictory.
OBJECTIVE: We aim to evaluate the correlation between the month of birth and the prevalence of AD in Malagasy children less than 3 years.
METHODS: A case-control study was conducted based on patients' data of the department of Dermatology in the University Hospital Joseph Raseta Befelatanana (UH/JRB) Antananarivo. It included 438 children less than 3 years seen in this department between January 2010 and December 2019. For each atopic dermatitis (AD) patient, two age-and sex-matched controls without a history of AD were selected from the same period.
RESULTS: This study included 146 AD cases and 292 non-AD controls. Our case-control study found that there is a statistically significant correlation between birth month and risk of AD in Malagasy children <3 years. Compared with people born in December, people born in April had the highest risk of AD (OR: 2.11, 95% CI 0.93-4.78), followed by people born in March (OR: 1.52, 95% CI 0.79-2,88). Asthma, allergic rhinitis and allergic conjunctivitis were significantly correlated with AD in our patients.
CONCLUSION: Our case-control study found that being born in April and March (dry season) may be associated with an increased risk of AD.
