[Research on the life stress and hypertension among young couples of childbearing age].

To investigate the current status of life stress and hypertension among couples of childbearing age across diverse economic regions in China, and to explore relevant influencing factors. This study was a cross-sectional study, with subjects from the "Research on the standardized system of comprehensive prevention and control of birth defects based on preconception-prenatal-postnatal whole chain". From February to May 2021, urban and rural couples of childbearing age (18-49 years old) from Beijing, Henan, and Gansu provinces were enrolled, representing the eastern, central, and western regions of China, respectively. The detection rate, cognition and control of hypertension in the general population, as well as the detection rate of hypertension in different genders and regions were analyzed. Subjects were divided into hypertensive group and non-hypertensive group based on whether their blood pressure was≥140/90 mmHg (1 mmHg=0.133 kPa), and the general clinical data of the two groups were compared. Subjects were also divided into prehypertension and hypertension group and normal blood pressure group based on whether their blood pressure was≥130/80 mmHg, and the general clinical data of the two groups were compared, with subgroup analyses conducted by gender. Multifactorial logistic regression model was applied to identify factors associated with prehypertension and hypertension in both males and females. A total of 1 942 couples of childbearing age, comprising 3 884 individuals, aged (29.8±5.2) years were enrolled, with 1 942 males (50.0%). The overall hypertension detection rate was 6.3% (246/3 884), with a detection rate of 10.5% (203/1 942) in males and 2.2% (43/1 942) in females. The hypertension detection rates in Beijing, Henan, and Gansu were 6.2% (92/1 482), 11.6% (139/1 200), and 1.2% (15/1 202), respectively. The overall detection rate of prehypertension and hypertension was 40.5% (1 574/3 884). Multifactorial logistic regression analysis showed that life pressure factors had no effect on female blood pressure levels (>0.05), while a significant or high level of life/work pressure was a risk factor for prehypertension and hypertension in males (=2.30, 95% 1.06-4.99, <0.05). The detection rate of prehypertension and hypertension among young couples of childbearing age in China is high, with poor awareness and control of hypertension. There are sex differences in the relationship between life pressure and blood pressure levels. Comprehensive consideration of individual living environments and mental health factors is crucial in blood pressure management. Measures to reduce life stress and enhance mental resilience should be implemented to address this public health issue.
