IntroductionMultimorbidity may confer higher risk for cognitive decline than any single constituent disease. This study aims to identify distinct trajectories of cognitive impairment probability among middle-aged and older adults, and to assess the effect of changes in mental-somatic multimorbidity on these distinct trajectories.
MethodsData from the Health and Retirement Study (1998–2016) were employed to estimate group-based trajectory models identifying distinct trajectories of cognitive impairment probability. Four time-varying mental-somatic multimorbidity combinations (somatic, stroke, depressive, stroke and depressive) were examined for their association with observed trajectories of cognitive impairment probability with age. Multinomial logistic regression analysis was conducted to quantify the association of sociodemographic and health-related factors with trajectory group membership.
ResultsRespondents (N = 20,070) had a mean age of 61.0 years (SD = 8.7) at baseline. Three distinct cognitive trajectories were identified using group-based trajectory modelling: (1) Low risk with late-life increase (62.6%), (2) Low initial risk with rapid increase (25.7%), and (3) High risk (11.7%). For adults following along Low risk with late-life increase, the odds of cognitive impairment for stroke and depressive multimorbidity (OR:3.92, 95%CI:2.91,5.28) were nearly two times higher than either stroke multimorbidity (OR:2.06, 95%CI:1.75,2.43) or depressive multimorbidity (OR:2.03, 95%CI:1.71,2.41). The odds of cognitive impairment for stroke and depressive multimorbidity in Low initial risk with rapid increase or High risk (OR:4.31, 95%CI:3.50,5.31; OR:3.43, 95%CI:2.07,5.66, respectively) were moderately higher than stroke multimorbidity (OR:2.71, 95%CI:2.35, 3.13; OR: 3.23, 95%CI:2.16, 4.81, respectively). In the multinomial logistic regression model, non-Hispanic Black and Hispanic respondents had higher odds of being in Low initial risk with rapid increase and High risk relative to non-Hispanic White adults.
ConclusionsThese findings show that depressive and stroke multimorbidity combinations have the greatest association with rapid cognitive declines and their prevention may postpone these declines, especially in socially disadvantaged and minoritized groups.
To describe stakeholder characteristics and perspectives about experiences, challenges and information needs related to the use of environmental scans (ESs).
Cross-sectional study.
A web-based survey platform was used to disseminate an online survey to stakeholders who had experience with conducting ESs in a health services delivery context (eg, researchers, policy makers, practitioners). Participants were recruited through purposive and snowball sampling. The survey was disseminated internationally, was available in English and French, and remained open for 6 weeks (15 October to 30 November 2022).
Descriptive statistics were used to describe the characteristics and experiences of stakeholders. Thematic analysis was used to analyse the open-text questions.
Of 47 participants who responded to the survey, 94% were from Canada, 4% from the USA and 2% from Australia. Respondents represented academic institutions (57%), health agency/government (32%) and non-government organisations or agencies (11%). Three themes were identified: (a) having a sense of value and utility; (b) experiencing uncertainty and confusion; and (c) seeking guidance. The data suggest stakeholders found value and utility in ESs and conducted them for varied purposes including to: (a) enhance knowledge, understanding and learning about the current landscape or state of various features of health services delivery (eg, programmes, practices, policies, services, best practices); (b) expose needs, service barriers, challenges, gaps, threats, opportunities; (c) help guide action for planning, policy and programme development; and (d) inform recommendations and decision-making. Stakeholders also experienced conceptual, methodological and practical barriers when conducting ESs, and expressed a need for methodological guidance delivered through published guidelines, checklists and other means.
ESs have value and utility for addressing health services delivery concerns, but conceptual and methodological challenges exist. Further research is needed to help advance the ES as a distinct design that provides a systematic approach to planning and conducting ESs.
