Health and Wellness Literacy Initiatives for Immigrant Populations Delivered Through Faith-Based Entities

Background: Health literacy has been shown to be low among immigrant populations globally, leading to limited ability to locate, access and use health information. Religious entities are often the initial contact for many immigrants regarding health and social supports, there are a lack of knowledge about how initiatives to improve health literacy of the immigrant population may be offered through faith-based entities. The objective of this proposed scoping review is to identify available evidence on health literacy initiatives delivered through faith-based entities for immigrant populations. Methods/Design: Using a scoping review framework we will complete a comprehensive search of relevant keywords in major academic and grey literature databases. Eligible articles will be identified through screening by two independent reviewers according to predefined inclusion and exclusion criteria to include articles relevant to our research question. Selected articles will be charted into data extraction tables for analysis, synthesis and presentation of narrative description and visual graphics. Discussion: This scoping review will identify and assess existing health literacy initiatives delivered through faith-based entities to improve health literacy of immigrant communities. This review will inform which initiatives are commonly practiced, and which immigrant groups are most benefitted from and can potentially be benefitted. It will also describe how to conduct those initiatives and what resources are needed and identify the stakeholders of such initiatives those needed to be engaged with to conduct a successful and acceptable program. The challenges and facilitators of those initiatives will also be identified

Undergraduate students’ perceptions of community engagement: A snapshot of a public research university in Canada

Students who participate in regular community engagement (CE) often experience benefits in different areas of their lives. Many academic institutions have implemented action plans to increase CE within the student population. At the University of Calgary, Canada, this is done primarily through its broader Eyes High strategy. As there remains a gap in the literature about students' perceptions of CE and their awareness of university CE strategies, this study aims to identify undergraduate students’ awareness of the Eyes High strategy, attitudes towards and levels of engagement, and challenges and potential methods to increase CE participation. Data was collected through a voluntary online survey (n=528). Participants were recruited through posters, social media, online faculty platforms and by faculty members. Survey results indicated students lacked knowledge regarding the Eyes High strategy. It was noted that students’ knowledge, attitudes and practices of CE increased as they spent more time at the university. The top perceived challenges to CE were lack of time, accessible information, support and incentives. To increase accessibility and student participation, we suggest introducing the Eyes High Strategy and CE activities early to the undergraduate population through workshops, credit-based courses and/or professional development requirements. Our data suggests that students are not well informed about the Eyes High strategy. There is thus a need for the university to build a campus-wide, student-informed initiative to proactively engage students. This research will serve as a gateway to further explore communicative methods that might better convey university priorities to students

Linking cohort data with administrative health data to develop a new hypertension prediction model to aid precision health approach

Introduction Hypertension is a common medical condition, affecting 1 in 5 Canadians, and is a major risk factor for heart attack, stroke, and kidney disease. Predicting the risk of developing incident hypertension may help to inform targeted preventive strategies. Objectives and Approach Identification of major risk factors and incorporation into a multivariable model for risk stratification may help to identify individuals who are at highest risk for developing incident hypertension and would potentially benefit most from intervention. The goal of the proposed research is to develop a robust hypertension prediction model for the general population using the Alberta Tomorrow Project (ATP) cohort data linked with Alberta’s administrative health data. ATP is Alberta's largest population health cohort, contains baseline data on socio-demographic characteristic, personal and family history of disease, medication use, lifestyle and health behavior, environmental exposures, physical measures and bio samples. Results Alberta’s administrative health data additionally provides information on health care utilization, enrollment, drugs, physician services, and hospital services. A prediction model for hypertension will be developed using logistic regression where information on candidate variables for the model will be gathered from ATP data and outcome (incident hypertension) will be ascertained from administrative health data (physicians/practitioner claim data and hospital discharge abstract data). Lacking follow-up information in current ATP data has laid the foundation of linking the two data sources through an anonymous unique person identifier (e.g. PHN) that will eventually provide follow-up information on ATP participants who are free of hypertension at baseline developed the disease as well as information on other potential variables. Conclusion/Implications The proposed prediction model will help to identify individuals at highest risk for developing hypertension and those who may benefit most from targeted healthy behavioral interventions and/or treatment. Such identification of high risk people may help prevent hypertension as well as the continuing costly cycle of managing hypertension and its complications

Color Coded Health Data: Factors related to willingness to share health information in South Asian community members in Canada

Introduction Data unavailability poses multiple challenges in many health fields, especially within ethnic subgroups in Canada, who may be hesitant to share their health data with researchers. Since health information availability is controlled by the participant, it is important to understand the willingness to share health information by an ethnic population to increase data availability within ethnocultural communities. Methods We employed a qualitative descriptive approach to better understand willingness to share health information by South Asian participants and operated through a lens that considered the cultural and sociodemographic aspect of ethnocultural communities. A total of 22 in-depth interviews were conducted between March and July 2020. Results The results of this study show that health researchers should aim to develop a mutually beneficial information-sharing partnership with communities, with an emphasis on the ethnocultural and socio-ecological aspects of health within populations. Conclusion The findings support the need for culturally sensitive and respectful engagement with the community, ethically sound research practices that make participants feel comfortable in sharing their information, and an easy sharing process to share health information feasibly

Kidney Function, Albuminuria and Life Expectancy

Background: Lower estimated glomerular filtration rate is associated with reduced life expectancy. Whether this association is modified by the presence or absence of albuminuria, another cardinal finding of chronic kidney disease, is unknown. Objective: Our objective was to estimate the life expectancy of middle-aged men and women with varying levels of eGFR and concomitant albuminuria. Design: A retrospective cohort study. Setting: A large population-based cohort identified from the provincial laboratory registry in Alberta, Canada. Participants: Adults aged ≥30 years who had outpatient measures of serum creatinine and albuminuria between May 1, 2002 and March 31, 2008. Measurements: Predictor : Baseline levels of kidney function identified from serum creatinine and albuminuria measurements. Outcomes : all cause mortality during the follow-up. Methods: Patients were categorized based on their estimated glomerular filtration rate (eGFR) (≥60, 45–59, 30–44, and 15–29 mL/min/1 · 73 m 2 ) as well as albuminuria (normal, mild, and heavy) measured by albumin-to-creatinine ratio or urine dipstick. The abridged life table method was applied to calculate the life expectancies of men and women from age 40 to 80 years across combined eGFR and albuminuria categories. We also categorized participants by severity of kidney disease (low risk, moderately increased risk. high risk, and very high risk) using the combination of eGFR and albuminuria levels. Results: Among men aged 50 years and with eGFR ≥60 mL/min/1.73 m 2 , estimated life expectancy was 24.8 (95% CI: 24.6–25.0), 17.5 (95% CI: 17.1–17.9), and 13.5 (95% CI: 12.6–14.3) years for participants with normal, mild and heavy albuminuria respectively. Life expectancy for men with mild and heavy albuminuria was 7.3 (95% CI: 6.9–7.8) and 11.3 (95% CI: 10.5–12.2) years shorter than men with normal proteinuria, respectively. A reduction in life expectancy was associated with an increasing severity of kidney disease; 24.8 years for low risk (95% CI: 24.6–25.0), 19.1 years for moderately increased risk (95% CI: 18.7–19.5), 14.2 years for high risk (95% CI: 13.5–15.0), and 9.6 years for very high risk (95% CI: 8.4–10.8). Among women of similar age and kidney function, estimated life expectancy was 28.9 (95% CI: 28.7–29.1), 19.8 (95% CI: 19.2–20.3), and 14.8 (95% CI: 13.5–16.0) years for participants with normal, mild and heavy albuminuria respectively. Life expectancy for women with mild and heavy albuminuria was 9.1 (95% CI: 8.5–9.7) and 14.2 (95% CI: 12.9–15.4) years shorter than the women with normal proteinuria, respectively. For women also a graded reduction in life expectancy was observed across the increasing severity of kidney disease; 28.9 years for low risk (95% CI: 28.7–29.1), 22.5 years for moderately increased risk (95% CI: 22.0–22.9), 16.5 years for high risk (95% CI: 15.4–17.5), and 9.2 years for very high risk (95% CI: 7.8–10.7). Limitations: Possible misclassification of long-term kidney function categories cannot be eliminated. Possibility of confounding due to concomitant comorbidities cannot be ruled out. Conclusion: The presence and degree of albuminuria was associated with lower estimated life expectancy for both gender and was especially notable in those with eGFR ≥30 mL/min/1.73 m 2 . Life expectancy associated with a given level of eGFR differs substantially based on the presence and severity of albuminuria

Polymorphisms in PPAR

Chronic kidney disease (CKD) is well known as a strong risk factor for both end stage renal disease and cardiovascular disease. To clarify the association of polymorphisms in the PPAR genes (PPARD, PPARG, and PPARGC1A) with the risk of CKD in Japanese, we examined this association among the Japanese subjects using the cross-sectional data of J-MICC (Japan Multi-Institutional Collaborative Cohort) Study. The subjects for this analysis were 3,285 men and women, aged 35–69 years, selected from J-MICC Study participants; genotyping was conducted by multiplex polymerase chain reaction-based Invader assay. The prevalence of CKD was determined for CKD stages 3–5 (defined as eGFR < 60 ml/min/1.73 m2). Participants with CKD accounted for 17.3% of the study population. When those with PPARD T-842C T/T were defined as reference, those with PPARD T-842C T/C and C/C demonstrated the OR for CKD of 1.26 (95%CI 1.04–1.53) and 1.31 (95%CI 0.83–2.06), respectively. There were no significant associations between the polymorphisms in other PPAR genes and the risk of CKD. The present study found a significantly increased risk of CKD in those with the C allele of PPARD T-842C, which may suggest the possibility of personalized risk estimation of this life-limiting disease in the near future

Mendelian Randomization on hs-CRP and eGFR

Background: Inflammation is thought to be a risk factor for kidney disease. However, whether inflammatory status is either a cause or an outcome of chronic kidney disease remains controversial. We aimed to investigate the causal relationship between high-sensitivity C-reactive protein (hs-CRP) and estimated glomerular filtration rate (eGFR) using Mendelian randomization (MR) approaches. Methods: A total of 10,521 participants of the Japan Multi-institutional Collaborative Cohort Study was analyzed in this study. We used two-sample MR approaches (the inverse-variance weighted (IVW), the weighted median (WM), and the MR-Egger method) to estimate the effect of genetically determined hs-CRP on kidney function. We selected four and three hs-CRP associated single nucleotide polymorphisms (SNPs) as two instrumental variables (IV): IVCRP and IVAsian, based on SNPs previously identified in European and Asian populations. IVCRP and IVAsian explained 3.4% and 3.9% of the variation in hs-CRP, respectively. Results: Using the IVCRP, genetically determined hs-CRP was not significantly associated with eGFR in the IVW and the WM methods (estimate per 1 unit increase in ln(hs-CRP), 0.000; 95% confidence interval [CI], −0.019 to 0.020 and −0.003; 95% CI, −0.019 to 0.014, respectively). For IVAsian, we found similar results using the IVW and the WM methods (estimate, 0.005; 95% CI, −0.020 to 0.010 and −0.004; 95% CI, −0.020 to 0.012, respectively). The MR-Egger method also showed no causal relationships between hs-CRP and eGFR (IVCRP: −0.008; 95% CI, −0.058 to 0.042; IVAsian: 0.001; 95% CI, −0.036 to 0.036). Conclusion: Our two-sample MR analyses with different IVs did not support a causal effect of hs-CRP on eGFR
