Prevalence of Premature Thelarche at 18 Months of Age: A Population- and Hospital-Based Study of Prevalence and Incidence in Girls Born at Northern Älvsborg County Hospital in Sweden

Conclusion: This is the first prospective population-based study of PT and it shows a prevalence of PT at age 18 months of 1.6/1,000. The incidence of clinically evaluated PT was 1.1/1,000. Our result is in line with other studies reporting the incidence of PT from medical records (0.4 –40/1,000). The outcome of PT in our study, as in the other studies, is that the great majority of girls show only benign symptoms.Horm Res Paediatr 2019;91:1 –7
