[Relationship of Cognitive Function With Menarche Age,Menopause Age, and Reproductive Period in Female Patients With...

Objective To explore the relationship of menarche age,menopause age,and reproductive period with cognitive function in the female patients with hypertension.Methods Hypertension screening was carried out in Wuyuan county of Jiangxi province from July to August in 2018.Data were collected through a face-to-face questionnaire survey,physical measurement,and biochemical tests.The cognitive function was scored according to the mini-mental state examination(MMSE)scale.Multiple linear regression and Logistic regression were employed to analyze the effects of menarche age,menopause age,and reproductive period on cognitive function,and the penalized spline regression to fit the curves.Results A total of 4595 postmenopausal women with hypertension were included in the analysis,with the mean age of(65.1±8.4)years,mean menarche age of(16.6±2.2)years,mean menopause age of(48.2±5.0)years,mean reproductive period of(31.7±5.5)years,mean MMSE score of(19.0±6.3)points,and total cognitive impairment detection rate of 40.4%(1859/4595).The detection rates of cognitive impairment were 28.4%,39.1%,and 45.8% in the females with the menarche ages of <15,15-16,and ≥17 years,47.9%,39.7%,and 38.3% in the females with the menopausal ages of <45,45-49,and ≥50 years,and 56.0%,44.4%,40.6%,and 32.6% in the females with the reproductive periods of <25,25-29,30-34,and ≥35 years,respectively.Moreover,the detection rates of cognitive impairment among different age groups were statistically significant(all P<0.05).Compared with the group with the menarche age <15 years,the groups with the menarche ages of 15-16 years and ≥17 years showed increased detection rates of cognitive impairment(OR=1.45,95%CI=1.19-1.75,P<0.001;OR=1.65,95%CI=1.37-1.98,P<0.001).Compared with the group with the menopausal age <45 years,the groups with the menopausal ages of 45-49 years and ≥50 years showed decreased detection rates of cognitive impairment(OR=0.80,95%CI=0.66-0.95,P=0.013;OR=0.78,95%CI=0.65-0.93,P<0.001).Compared with the group with the reproductive period <25 years,the groups with the reproductive periods of 25-29,30-34,and ≥35 years showed decreased detection rates of cognitive impairment(OR=0.66,95%CI=0.52-0.84,P<0.001;OR=0.62,95%CI=0.50-0.76,P<0.001;OR=0.51,95%CI=0.41-0.63,P<0.001).Conclusion The detection rate of cognitive impairment had a positive correlation with menarche age and negative correlations with menopause age and reproductive period in the female patients with hypertension.
