Microbes, Allergy, Asthma, and Pets birth cohort (MAAP)
The Microbes, Asthma, Allergy and Pets (MAAP) birth cohort is designed to study the effects of indoor dog exposure on early-life gut microbiome development and the risk of asthma and allergies in children. Pregnant women aged 18-49, receiving healthcare from Henry Ford Health System, were recruited if they lived with indoor dogs or in pet-free households for at least 2 years before pregnancy. MAAP includes 141 maternal–child pairs from southeastern Michigan in the United States of America. Participants were followed up at four time points: prenatal, 1-week post-delivery, 6 months post-delivery, and 18 months post-delivery.
