Association between depression and stroke and the role of sociodemographic factors: A study among hypertensive populations

OBJECTIVES

Studies have shown that depression increases the risk of stroke, and that this relationship can be modified by sex. However, few studies have explored this relationship in a hypertensive population, and an examination of sociodemographic factors may be useful in determining whether depression and stroke are related.

MATERIALS AND METHODS

We used data from the National Health and Nutrition Examination Survey conducted between 2005-2018. The relationship between depression and stroke was investigated using a multivariate logistic regression. Effect modification by sex was examined using an interaction analysis model.

RESULTS

Participants with mild or moderate depression had a 53 % (odds ratio, [OR] 1.53; 95 % confidence interval [CI], 1.15-2.04) higher risk of stroke than those without depression, with 1.76 times (95 % CI, 1.14-2.72) greater risk for major depression. Interaction analysis indicated that sex had no effect on this relationship (OR, 1.30; 95 % CI, 0.85-1.47, P=0.430). In comparison with Hispanics, non-Hispanic blacks and others/mixed-race individuals with depression had a greater risk of stroke (OR, 2.26; 95 % CI, 1.5-3.14; OR, 2.67, 95 % CI, 1.29-5.55).

CONCLUSIONS

Our study found that the degree of depression was positively correlated with stroke in a hypertensive population, and that this relationship was not affected by sex.

Association between hypertension and stroke in US adults in the National Health and Nutrition Examination Surveys (NHANES) 2007 to 2018

BACKGROUND

Hypertension is associated with stroke events. The purpose of this study was to analyze the correlation between hypertension and stroke in American adults from 2007 to 2018 in National health and Nutrition Examination Survey (NHANES) database.

METHODS

28528 individuals in the NHANES from 2007 to 2018 were included in the cross-sectional analysis. The independent variable was blood pressure (BP) and the outcome variable was stroke. Multivariate linear regression model was used to study the correlation between BP and stroke.

RESULTS

In each multivariate linear regression model, BP level was positively correlated with stroke, and this positive correlation was stable in both men and women (man OR: 1.36, 95% CI: 0.95 to 1.69; woman OR: 1.45, 95% CI: 1.12 to 1.78).

CONCLUSION

Our results show that there is a significant positive correlation between BP and stroke. When the systolic blood pressure (SBP) is about 140 mmHg, the risk of stroke is the lowest; Male patients with diastolic blood pressure (DBP) of about 80 mmHg have a lower risk of stroke.
