However, there have been no studies on the association between WBC counts and the risk of hypertension in young adults.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This cohort study conducted in Taiwan included a total of 2351 military personnel who were aged 18\u201339 years, were free of baseline hypertension and were followed up for incident hypertension from 2014 to the end of 2020. Resting blood pressure (BP) was measured during each annual health examination, while blood WBC counts and a biochemical panel were checked at baseline (2014). Incident hypertension was diagnosed as a systolic BP\u2009\u2265\u2009130\u2009mmHg and\/or a diastolic BP\u2009\u2265\u200980\u2009mmHg and\/or the use of antihypertensive medications. Smooth curve fitting and multivariable Cox hazard proportional regression analysis, controlling for baseline sex, age, substance use, body mass index, BP, physical activity, serum uric acid level and kidney function, were used to determine the association between the baseline WBC count and incident hypertension.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      During a median follow\u2010up of 6.1 years, 885 participants (37.6%) developed incident hypertension.
