Factors associated with quality of life among newly diagnosed acute ischemic stroke patients: a community-based case-control study

Abstract

Background: Stroke burden is expected to increase and surviving a bout of stroke may leave one with a chronic or disabling outcome decreasing significantly the quality of life of the sufferer. The study aimed to explore the association between quality of life (QoL) in stroke and non-stroke individuals in a predominantly agricultural community. Method: A community-based case-control study was conducted among 154 cases aged 18 and 75 diagnosed with incident stroke. Controls were 554 non-stroke individuals (n = 554) recruited from a community where cases resided. Cases and controls were matched for age, gender and residential area. Using a self-reported questionnaire of the World Health Organization Quality of Life (WHOQOL-BREF), socio-demographic characteristics and lifestyle habits were measured in association with QoL. Statistical analyses included multivariable logistic regression models, adjusted odds ratio (aOR) and 95% confidence interval (CI). Results: Significant predictors associated with low-medium QoL were having a larger waist circumference (aOR = 1.619, 95%CI [1.003–2.612]) and being a farmer (aOR = 2.976, 95%CI [1.143–7.750]) but having a current smoking habit and being male were at lesser odds with low-medium QoL (aOR = 0.381, 95%CI [0.191–0.757]) and (aOR = 0.564, 95%CI [0.323–0.985]) respectively. In all domains, women were at a higher risk of low-medium QoL while in physical health and environment domains, it was having a larger waist circumference. In both physical health and psychological domains, being married was protective to low-medium QoL so also being age 39 or younger and having a higher education in social relationship domain. Conclusion: Waist circumference, occupation, smoking habit and gender are associated with low-medium QoL. Addressing the influence of such factors could create an additional therapeutic line in the primary prevention of stroke in at-risk populations.
