Association between age at menarche and prehypertension in female college students / 中国学校卫生

ABSTRACT

Objective@#To explore the correlation of age at menarche and prehypertension in female college students.@*Methods@#Age at menarche of 558 female college students was collected, while blood pressure, height and weight were measured, and body mass index(BMI) was calculated.@*Results@#Average age at menarche was (12.48±0.95) years, prevalence of prehypertension was 17.56% (98/558). The age of menarche was 8-11, 12, 13, 14, 15-19, and the prevalence of hypertension was 30.95%, 10.00% , 17.31%, 10.81%, 31.58% respectively, U shape association was observed in the association between prehypertension with age at menarche, lowest when age at menarche was <12 years. There was no significant difference in prehypertension between age at menarche was 13, 14 years old with 12-year-old group, those age at menarche 8-11 or 15-19 had a significantly higher risk of developing prehypertension than those 12-year-old( OR =4.03, 4.15, P <0.05).@*Conclusion@#Early or late menarche is associated with high blood pressure, appropriate intervention for girls with early menarche and obesity may be beneficial in reducing their future hypertension.
