Age differences in the associations of behavioral and psychosocial factors with stroke

Exploring the Impact of Illness Perceptions, Self-efficacy, Coping Strategies, and Psychological Distress on Quality of Life in a Post-stroke Cohort

This study evaluated the mediating role of self-efficacy, coping, depression and anxiety on the relationship between illness perceptions and quality of life in stroke survivors (n = 72; 32 females; mean [SD] age 65.09 [14.14] years; male mean [SD] age 69.83 [11.81]). Illness perceptions (Brief Illness Perceptions Questionnaire; BIPQ), coping styles (Carver Brief-COPE scale; B-COPE), depression/anxiety (Hospital Anxiety and Depression Scale; HADS), self-efficacy (General Self-Efficacy Scale; GSE) and quality of life (Assessment of quality of life; AQOL-6D) were analysed. Correlation analyses showed illness perception, maladaptive coping, self-efficacy, depression and anxiety to have a significant negative relationship with quality of life. Mediation analyses showed that while maladaptive coping and self-efficacy did not mediate the relationship between illness perception and quality of life, depression and anxiety did. The final model explained 76.74% of the variance in quality of life. Although based on a relatively small sample size, these results provide evidence for the important role of psychosocial factors in quality of life in post-stroke cohorts.

Differences in healthcare visit frequency and type one year prior to stroke among young versus middle-aged adults

Background

The incidence and prevalence of stroke among the young are increasing in the US. Data on healthcare utilization prior to stroke is limited. We hypothesized those < 45 years were less likely than those 45–65 years old to utilize healthcare in the 1 year prior to stroke.

Methods

Patients 18–65 years old who had a stroke between 2008 and 2013 in MarketScan Commercial Claims and Encounters Databases were included. We used descriptive statistics and logistic regression to examine healthcare utilization and risk factors between age groups 18–44 and 45–65 years. Healthcare utilization was categorized by visit type (no visits, inpatient visits only, emergency department visits only, outpatient patient visits only, or a combination of inpatient, outpatient or emergency department visits) during the year prior to stroke hospitalization.

Results

Of those 18–44 years old, 14.1% had no visits in the year prior to stroke compared to 11.2% of individuals aged 45–65 [OR = 1.30 (95% CI 1.25,1.35)]. Patients 18–44 years old had higher odds of having preventive care procedures associated with an outpatient visit and lower odds of having cardiovascular procedures compared to patients aged 45–65 years. Of stroke patients aged 18–45 and 45–65 years, 16.8 and 13.2% respectively had no known risk for stroke.

Conclusions

Patients aged 45–65 were less commonly seeking preventive care and appeared to be seeking care to manage existing conditions more than patients aged 18–44 years. However, as greater than 10% of both age groups had no prior risk, further exploration of potential risk factors is needed.

Race, Marital History, and Risks for Stroke in US Older Adults

Stroke is among the leading causes of disability and death in the United States, and racial differences are greater for stroke than for all other major chronic diseases. Considering the equally sizeable racial disparities in marital life and associated risks across adulthood, the current study hypothesizes that black-white differences in marital history play an important role in the large racial inequalities in the incidence of stroke. The major objective are to (i) demonstrate how marital history is associated with the incidence of stroke, (ii) examine how marital factors mediate and/or moderate racial disparities in stroke, and (iii) examine the factors that may explain the associations. Using retrospective and prospective data from the Health and Retirement Study (n = 23,289), the results show that non-Hispanic (NH) blacks have significantly higher rates of marital instability, greater numbers of health-risk factors, and substantially higher rates of stroke compared with NH whites. Contrary to the cumulative disadvantage hypothesis, findings from discrete-time-hazard models show that the effects of marital history are more pronounced for NH whites than for NH blacks. Risks for stroke were significantly higher in NH whites who were currently divorced, remarried, and widowed, as well as in those with a history of divorce or widowhood, compared with NH whites who were continuously married. In NH blacks, risks for stroke were elevated only in those who had either never married or had been widowed-with no significant risks attributable to divorce. The potential mechanisms underlying the associations are assessed, and the implications of the findings are discussed.
