Abstract Aims  The incidence of type 1 diabetes has increased over the last decades. The pathological pathway is not yet clear, even if genetic and environmental risk factors are known. An early diagnosis can avoid ketoacidosis and its complications. This work aims to discuss the determinants of both ketoacidosis at the onset and access by hospital emergency departments without a suspected diagnosis. Methods  An observational bi-centric prospective study was conducted in Northern Italy, on a paediatric population including Italian and migrant patients at the diabetes onset. Seventy-four type 1 diabetes patients, both Italian and migrant, were included in the study. Anthropometric, socio-economic, behavioural, clinical data were collected, and microbiota analyses were performed using stool samples. Results  Regular physical activity is associated with lower ketoacidosis incidence at onset (OR 0.33 95% CI 0.12–0.95 p
