Participant education, spousal education and dementia risk in a diverse cohort of members of an integrated health care delivery system in Northern California.

ABSTRACT:

Objective

The role of spousal education on dementia risk and how it may differ by gender or race/ethnicity is unknown. This study examines the association between one's own education separate from and in conjunction with spousal education and risk of dementia.

Design

Cohort.

Setting

Kaiser Permanente Northern California (KPNC), an integrated health care delivery system.

Participants

8835 members of KPNC who were aged 40-55, married and reported own and spousal education in 1964-1973.

Primary outcome measure

Dementia cases were identified through medical records from 1 January 1996 to 30 September 2017.

Methods

Own and spousal education was self-reported in 1964-1973 and each was classified as four indicator variables (≤high school, trade school/some college, college degree and postgraduate) and as ≥college degree versus ResultsThe cohort was 37% non-white, 46% men and 30% were diagnosed with dementia during follow-up from 1996 to 2017 (mean follow-up=12.7 years). Greater participant education was associated with lower dementia risk independent of spousal education, demographics and health indicators. Greater spousal education was associated with lower dementia adjusting for demographics but became non-significant after further adjustment for participant education. The same pattern was seen for spousal education ≥college degree (not adjusting for participant education HR_{spousal education≥college degree}=0.83 (95% CI: 0.76 to 0.90); adjusting for participant education HR_{spousal education≥college degree}=0.92 (95% CI: 0.83 to 1.01)). These associations did not vary by gender or race/ethnicity.

Conclusion

In a large diverse cohort, we found that higher levels of participant's own education were associated with lower dementia risk regardless of spousal education. An inverse association between spousal education and dementia risk was also present, however, the effects became non-significant after adjusting for participant education.

Project description:IntroductionIn an effort to identify improvement opportunities for earlier dementia detection and care within a large, integrated health care system serving diverse Medicare Advantage (MA) beneficiaries, we examined where, when, and by whom Alzheimer's disease and related dementias (ADRD) diagnoses are recorded as well as downstream health care utilization and life care planning.MethodsPatients 65 years and older, continuously enrolled in the Kaiser Foundation health plan for at least 2 years, and with a first ADRD diagnosis between January 1, 2015, and December 31, 2018, comprised the incident cohort. Electronic health record data were used to identify site and source of the initial diagnosis (clinic vs hospital-based, provider type), health care utilization in the year before and after diagnosis, and end-of-life care.ResultsADRD prevalence was 5.5%. A total of 25,278 individuals had an incident ADRD code (rate: 1.2%) over the study period-nearly half during a hospital-based encounter. Hospital-diagnosed patients had higher comorbidities, acute care use before and after diagnosis, and 1-year mortality than clinic-diagnosed individuals (36% vs 11%). Many decedents (58%-72%) received palliative care or hospice. Of the 55% diagnosed as outpatients, nearly two-thirds were diagnosed by dementia specialists; when used, standardized cognitive assessments indicated moderate stage ADRD. Despite increases in advance care planning and visits to dementia specialists in the year after diagnosis, acute care use also increased for both clinic- and hospital-diagnosed cohorts.DiscussionSimilar to other MA plans, ADRD is under-diagnosed in this health system, compared to traditional Medicare, and diagnosed well beyond the early stages, when opportunities to improve overall outcomes are presumed to be better. Dementia specialists function primarily as consultants whose care does not appear to mitigate acute care use. Strategic targets for ADRD care improvement could focus on generating pragmatic evidence on the value of proactive detection and tracking, care planning, and the role of specialists in chronic care management.

Project description:Background: Dementia does not merely affect individuals, the carer and the person living with dementia, but also has a profound impact on their spousal relationship. As such, this study aimed to gain a deeper understanding of how dementia affects spousal relationships with a focus on interpersonal (i.e. relationship adjustment, communication engagement and emotional connection between two individuals) and intrapersonal (i.e. loss of self within the context of relationships) dynamics using a qualitative approach. The study also explored how carers adapt to such relationship challenges in the context of dementia care.Methods: A phenomenological approach was used to capture the subjective experiences of female spousal carers, who regularly support their partner living with dementia. A total of nine semi-structured interviews were conducted.Results: Relationship adjustment theme highlighted how learning to acknowledge role shifts from a spouse to a carer is critical for carers to manage relationship difficulties. Emotional connection theme demonstrated the importance of reminiscing about the shared history between dyads to cope with feelings of loss of affective intimacy. Communication engagement theme revealed carers' need to learn a new way of communicating due to the decrease in meaningful communication and two-way interaction. Sense of self theme highlighted the importance of self-compassion to overcome feelings of self-loss and isolation.Conclusion: Findings suggest that improving the relationship between female spousal carers and their partner living with dementia may require targeted interventions addressing different factors. Such interventions can include a couple's life story approach to enable couples to reminisce about their shared experiences, interactive communication training to enhance meaningful engagements, and a psychological approach such as compassion-focused therapy to overcome emotional challenges and facilitate self-compassion.

Project description:Ecologic analyses, case-case comparisons, and animal experiments suggest positive associations between air pollution and tuberculosis.We evaluated this hypothesis in a large sample, which yielded results that are applicable to the general population.We conducted a case-control study nested within a cohort of Kaiser Permanente of Northern California members. All active pulmonary tuberculosis (TB) cases newly diagnosed between 1996 and 2010 (n = 2,309) were matched to two controls (n = 4,604) by age, sex, and race/ethnicity on the index date corresponding with the case diagnosis date. Average individual-level concentrations of carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), and particulate matter with aerodynamic diameter ? 2.5 ?m (PM2.5) and 10 ?m (PM10) for 2 years before diagnosis/entry into the study were estimated using measurements from the California Air Resources Board monitor closest to the participant's residence.In single-pollutant adjusted conditional logistic regression models, the pulmonary TB odds ratios (95% confidence intervals) for the highest quintile (vs. lowest) were 1.50 (95% CI: 1.15, 1.95) for CO and 1.42 (95% CI: 1.10, 1.84) for NO2. Corresponding estimates were higher among never [1.68 (95% CI: 1.26, 2.24)] than ever [1.19 (95% CI: 0.74, 1.92)] smokers for CO. In contrast, for NO2, estimates were higher among ever [1.81 (95% CI: 1.13, 2.91)] than never [1.29 (95% CI: 0.97, 1.71)] smokers. O3 was inversely associated for smokers [0.66 (95% CI: 0.43, 1.02)] and never smokers [0.65 (95% CI: 0.52, 0.81)]. No other consistent patterns were observed.In this first, to our knowledge, U.S. nested case-control study on air pollution and pulmonary TB, we observed positive associations with ambient CO and NO2, which require confirmation.Smith GS, Van Den Eeden SK, Garcia C, Shan J, Baxter R, Herring AH, Richardson DB, Van Rie A, Emch M, Gammon MD. 2016.
