This study analyzed health and lifestyle characteristics of those with diagnosed and possible PCOS in a large, digital cohort.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We analyzed data from female participants who enrolled in the Apple Women\u2019s Health Study-a mobile-application-based cohort in the United States and provided informed consent from 11\/14\/2019\u201312\/14\/2024. Specific analyses were further restricted to those who responded to relevant survey questions. Self-reported sociodemographic, health (conditions and age at diagnosis), and lifestyle characteristics were evaluated, stratified by PCOS status: PCOS (self-reported physician diagnosed PCOS), possible PCOS (self-reported irregular menses and androgen excess), and no PCOS. Among those with PCOS\/possible PCOS, we further evaluated potential predictors of not reporting a PCOS diagnosis using multivariable logistic regression.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of participants providing medical history at enrollment, 12.6% (n=11,022) reported PCOS, and among the subset without a PCOS diagnosis and with relevant survey data, 17.4% (n=7,152) were assigned possible PCOS. The median baseline age was 35 years. Most participants self-identified as non-Hispanic White (74.2%). The possible PCOS group was slightly less educated (\u2264high school: possible PCOS 14.5%, PCOS 17.3%, no PCOS 14.0%). The PCOS\/possible PCOS groups reported lower socioeconomic status (SES) than the no PCOS group (low SES: PCOS 32.7%, possible PCOS 31.6%, no PCOS 23.5%). The PCOS and possible PCOS groups displayed a high burden of disease (cardiometabolic, endometrial hyperplasia\/cancer, pregnancy complications, mental health conditions). Compared to those without PCOS, those with PCOS reported less healthy lifestyle behaviors relevant to physical activity\/sleep\/stress\/smoking and more healthy lifestyle behaviors relevant to alcohol intake\/diet. The age at diagnosis for multiple health conditions was earlier for participants with PCOS compared to those without PCOS. Young\/old age (18\u00a0-\u00a029\/40\u201350 years), lower educational attainment, lower SES, and lower BMI were positive predictors of not reporting a PCOS diagnosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This study demonstrated significant differences in health and lifestyle characteristics across PCOS status (PCOS, possible PCOS, no PCOS), identifying populations that could benefit from early risk reduction counseling.
