Independent Correlates of Glycemic Control among Adults with Diabetes in South Africa

BACKGROUND

Globally, the prevalence of diabetes is increasing, especially in low- and middle-income countries (LMICs), including those in the sub-Saharan African region. However, the independent socioeconomic correlates of glycemic control as measured by hemoglobin A1C have yet to be identified. Therefore, the aim of this analysis was to understand the independent correlates of glycemic control in South Africa.

METHODS

Data from the 2016 South Africa Demographic and Health Survey on adults with diabetes were used for this analysis. The dependent variable, glycemic control, was defined using hemoglobin A1c (HbA1c). Independent variables included: age, gender, ethnicity, marital status, region, urban/rural residence, ability to read, education, insurance, wealth, occupation, and employment in the last year. Analysis of variance was used to test for differences in mean HbA1c for each category of all independent variables, and a fully adjusted linear regression model was used to identify independent correlates of glycemic control (HbA1c).

RESULTS

Among the 772 people included in this analysis, there were significant differences in mean HbA1c by age (p < 0.001), ethnicity (p < 0.001), place of residence (p = 0.024), wealth index (p = 0.001), and employment in the last year (p = 0.008). Independent correlates of HbA1c included age, ethnicity, and wealth index.

CONCLUSIONS

This study used data from a large diverse population with a high prevalence of diabetes in sub-Saharan Africa and provides new evidence on the correlates of glycemic control and potential targets for interventions designed to lower HbA1c and improve diabetes-related health outcomes of adults in South Africa.

Differential Effect of Patient- and Provider-Level Factors on Patient Satisfaction Scores in Academic General Internal Medicine Clinics

OBJECTIVE

Determine whether patient-level or provider-level factors have greater influence on patient satisfaction scores in an academic general internal medicine clinic.

METHODS

Two years of data (2017-2019) from the Clinician and Group Consumer Assessment of Healthcare Providers and Systems (CGCAHPS) surveys from ambulatory internal medicine clinic visits in an academic health center located in the Midwest United States were used. Patient satisfaction was measured using the overall provider satisfaction score (0-10), dichotomized with 9-10 defined as satisfactory and 0-8 as unsatisfactory. Provider-level independent variables included age, sex, race/ethnicity, provider type, service type, clinical effort, academic rank, and years since graduation. Patient-level factors included age, sex, race/ethnicity, education, and Epic Risk Score. Generalized mixed-effects logistic regression models were used to investigate associations between top-box satisfaction score and patient- and provider-level factors, accounting for the nesting of patients within providers.

RESULTS

Thirty-three providers and 4597 patients were included in the analysis. Male providers (OR, 1.57; 95% CI, 1.00, 2.47), minority group 2 (OR, 3.54; 95% CI, 1.24, 10.07) and minority group 3 (OR, 6.04; 95% CI, 1.45, 25.12), faculty (OR, 3.83; 95% CI, 1.56, 9.36), and primary care providers (OR, 5.60; 95% CI, 1.62, 19.34) had increased odds of having a top-box rating compared with females, minority group 1, advanced practice providers, and perioperative providers respectively. Age was the only patient independent correlate of top-box rating with a 3% increased odds of top-box rating for every year increase in age (OR, 1.03; 95% CI 1.02, 1.03).

CONCLUSIONS

In this academic general internal medicine clinic, top-box satisfaction scores were more strongly associated with provider-level factors, including provider race/ethnicity, provider type, and service type, as opposed to patient-level factors. Further research is needed to confirm these findings and identify potential system-level interventions.

Understanding the Relationship Between Wealth and Cognitive Function by Race/Ethnicity Among Older United States Adults with Diabetes

Background

The prevalence of type 2 diabetes is increasing with the burden disproportionately falling on older adults and racial/ethnic minorities. Older adults with diabetes show greater cognitive decline and there are disparities in cognitive function by race/ethnicity that can be explained by social determinants such as wealth.

Objective

To understand whether there is a differential relationship between wealth and cognitive function by race/ethnicity among older U.S. adults with diabetes.

Methods

Data on 9,006 adults aged 50+ with diabetes from the Health and Retirement Study (2006-2016) were analyzed. The primary outcome, cognitive function, was a score ranging from range 0-27 categorized as: normal [12-27], mild cognitive impairment (MCI) [7-11], and dementia including Alzheimer's disease [0-6]. Three modeled outcomes were: 1) normal versus MCI, 2) normal versus dementia, 3) MCI versus dementia. Wealth was log transformed and used as continuous and binary (≥median,

Results

In adjusted models, greater wealth was significantly associated with lower odds of MCI and dementia for all groups. Similarly, having wealth less than the sample median was associated with higher odds of MCI and dementia compared to wealth≥sample median.

Conclusions

Increased wealth was significantly protective against MCI and dementia for all ethnic groups. Wealth less than the sample median was associated with greater odds of dementia for NHB and NHW.

Randomized controlled trial of technology-assisted case management in low-income adults with type 2 diabetes: Effect on quality of life and blood pressure

INTRODUCTION

A novel randomized controlled trial tested the efficacy of a technology-assisted case management program in a low income, rural population previously where nurses titrated medication over the phone instead of in a clinic. The primary analysis showed significant improvement in glycemic control at 6 months post-randomization decreasing hemoglobin A1c by 1%. This study aimed to test if the intervention was also effective at decreasing blood pressure without compromising quality of life.

METHODS

A total of 113 adults with poorly controlled diabetes (hemoglobin A1c ≥ 8%) were randomly assigned to the technology-assisted case management intervention or usual care. Participants received a 2-in-1 telehealth system to monitor glycemic and blood pressure control, which was uploaded daily to a central server. A nurse case manager was trained to titrate medication under physician supervision every 2 weeks based on the readings. Outcomes were blood pressure and quality of life (12-item Short-Form Health Survey) at 6 months. Baseline adjusted mixed models using a random intercept were used to evaluate change at 6 months for the technology-assisted case management intervention group compared to usual care.

RESULTS

There were no statistically significant differences in systolic blood pressure, physical component of quality of life, or mental component of quality of life between the technology-assisted case management and control group. However, there was a significant change in diastolic blood pressure over time, with the technology-assisted case management group decreasing at 6 months (p = .05), whereas the control group remained stable.

CONCLUSIONS

Technology-assisted case management by a nurse with medication titration under physician supervision was efficacious in improving diastolic blood pressure without compromising quality of life in low-income rural adults with diabetes.

Incidence of Esophageal Adenocarcinoma, Mortality, and Esophagectomy in Barrett's Esophagus Patients Undergoing Endoscopic Eradication Therapy

INTRODUCTION

Endoscopic eradication therapy (EET) is the preferred treatment for Barrett's esophagus (BE)-related neoplasia patients. However, the impact of EET on critical outcomes, outside of clinical trials and registry data, remains scarcely studied. We aimed to assess real-world practice patterns and clinical outcomes among BE patients undergoing EET.

METHODS

TriNetX is a large research network comprising linked inpatient and outpatient electronic-health record-derived data from over 80,000,000 patients. Patients with a diagnosis of BE from 2015 to 2020 were identified and included if they underwent EET during the study period. The primary outcome was the progression to EAC after index EET. Secondary outcomes included rate of esophagectomy, and all-cause mortality. All outcomes were stratified by baseline histology. The incidence of EAC and all-cause mortality were reported in person-years and adjusted for age and sex.

RESULTS

A total of 4114 patients were analyzed. Distribution of baseline histology was as follows: NDBE (11.8%), LGD (21.4%), HGD (26.4%), EAC (20.8%), and unspecified (19.6%). The total incidence of EAC after index EET was 6.01 per 1000 person-years (PY) for the entire cohort with the highest rate in HGD patients (12.9/1000 PY). The incidence of all-cause mortality was 13.23 per 1000 PY with the highest rates in EAC patients (25.1 per 1000 PY). Rates of esophagectomy were < 1% for all grades of dysplasia.

CONCLUSION

The results of this study provide "real-world" data on critical outcomes for BE patients undergoing EET, demonstrating a low risk of incident EAC, all-cause mortality, and need for esophagectomy.

Prevalence and correlates of pre-diabetes in Sub-Saharan Africa using Demographic and Health Survey Data: a cross-sectional study

OBJECTIVE

The objective is to investigate the prevalence of pre-diabetes in Namibia and South Africa and to determine sociodemographic correlates of disease using population data.

DESIGN

Cross-sectional study.

SETTING

Demographic and Health Survey for emerging (Namibia) and established (South Africa) economies in Sub-Saharan Africa collected laboratory data that allowed determination of pre-diabetes status.

PARTICIPANTS

3141 adults over age 18 from the 2013 Namibia survey, weighted to a population of 2176, and 4964 adults over age 18 from the 2016 South Africa survey, weighted to a population of 4627 had blood glucose/glycated haemoglobin (HbA1c) and diabetes information were included in the analysis.

OUTCOME MEASURES

Pre-diabetes was defined as not being diagnosed with diabetes and having a blood sugar measurement of 100-125 mg/dL in Namibia or an HbA1c measurement of 5.7%-6.4%. Logistic models were run for each country separately, with pre-diabetes as the outcome and a series of sociodemographic variables (age, gender, urban/rural residence, number of children, employment status, wealth index, education level, and ethnicity (in South Africa) or religion (in Namibia)) entered as variables to investigate the independent relationship of each.

RESULTS

The weighted prevalence of pre-diabetes was 18.7% in Namibia and 70.1% in South Africa. Rural residence was independently associated with higher odds of pre-diabetes in Namibia (1.47, 95% CI 1.05 to 2.06), while both younger age (0.98, 95% CI 0.97 to 0.99) and urban residence (0.80, 95% CI 0.66 to 0.99) were independently associated with odds of pre-diabetes in South Africa.

CONCLUSIONS

The prevalence of pre-diabetes was 18.7% in Namibia and 70.1% in South Africa. Correlates of pre-diabetes differed between the two countries with rural residents having higher odds of pre-diabetes in Namibia and urban residents with higher odds in South Africa. Aggressive interventions, including population level education and awareness programmes, and individual level education and lifestyle interventions that account for country-specific contextual factors are urgently needed to prevent progression to diabetes.

Relationship between Satisfaction Scores and Racial/Ethnic and Sex Concordance in Primary Care

Racial/ethnic and sex concordance between patients and providers has been suggested as an important consideration in improving satisfaction and increasing health equity. We aimed to guide local efforts by understanding the relationship between satisfaction with care and patient-provider racial/ethnic and sex concordance within our academic medical center's primary care clinic.

METHODS

Satisfaction data for encounters from August 2016 to August 2019 were matched to data from the medical record for patient demographics and comorbidities. Data on 33 providers were also obtained, and racial/ethnic and sex concordance between patients and providers was determined for each of the 3672 unique encounters. The primary outcome was top-box scoring on the CGCAHPS overall satisfaction scale (0-8 vs. 9-10). Generalized mixed-effects logistic regression, including provider- and patient-level factors as fixed effects and a random intercept effect for providers, were used to determine whether concordance had an independent relationship with satisfaction.

RESULTS

89.0% of the NHW-concordant pairs and 90.4% of the Minority Race/Ethnicity-concordant pairs indicated satisfaction, while 90.1% of the male-concordant and 85.1% of the female-concordant pairs indicated satisfaction. When fully adjusted, the female-concordant (OR = 0.58, 95% CI 0.35-0.94) and male-discordant (OR = 0.68, 95% CI 0.51-0.91) pairs reported significantly lower top-box satisfaction compared to the male-concordant pairs. Significant differences did not exist in racial/ethnic concordance.

CONCLUSIONS

In this sample, differences in sex concordance were noted; however, patient- and provider-level factors may be more influential in driving patient satisfaction than race/ethnicity in this health system.

Examining the Relationship between Social Determinants of Health and Adverse Pregnancy Outcomes in Black Women

OBJECTIVE

 Our objective was to examine associations between social determinants of health (cultural, neighborhood, and psychosocial factors) and adverse pregnancy outcomes (gestational age at birth [GAB], preterm birth [PTB], and preeclampsia) in Black women.

STUDY DESIGN

 Cross-sectional data (n = 204) comprised adult Black women aged ≥18 years who delivered between 2013 and 2022 in Milwaukee,Wisconsin. Sequential unadjusted linear and logistic regression models were run to evaluate associations between social determinants of health and pregnancy outcomes. Stepwise regressions with forward selection were run to test the contribution of the social determinants of health to adverse pregnancy outcomes, independent of the contribution of established risk factors.

RESULTS

 Mean GAB was 37.9 weeks, 19.6% had a PTB and 17.7% had preeclampsia. In all fully adjusted models, education (β0.15, 95% confidence interval [CI]: 0.005, 0.29), nulliparity (β -1.26, 95%CI: -2.08, -0.44), multifetal gestation (β -2.67, 95% CI: -4.29, -1.05), and exposure to neighborhood violence (β -0.13, 95%CI: -0.25, -0.005) were associated with shortened GAB. Education (adjusted odds ratio [aOR]: 0.83, 95%CI: 0.69, 0.99), provider trust (aOR: 0.94, 95%CI: 0.88, 0.99), chance health locus of control (aOR: 0.88, 95%CI: 0.78, 0.99), and anxiety (aOR: 0.81, 95%CI: 0.69, 0.95) were associated with reduced odds of PTB. Powerful others health locus of control (aOR: 1.16, 95%CI: 1.03, 1.32), depression (aOR: 1.17, 95%CI: 1.01, 1.34), nulliparity (aOR: 4.73, 95%CI: 1.79, 12.55), multifetal gestation (aOR: 17.78, 95%CI: 3.49, 90.50), diabetes (aOR: 4.71, 95%CI: 1.17, 19.00), and obstructive sleep apnea (aOR: 44.28, 95%CI: 2.50, 783.12) were associated with increased odds of PTB. Internal health locus of control (aOR: 1.13, 95%CI: 1.01, 1.25), depression (aOR: 1.09, 95%CI: 1.01, 1.17), preeclampsia in a previous pregnancy (aOR: 5.96, 95% CI: 2.22, 16.01), and kidney disease (aOR: 34.27, 95% CI: 1.54, 763.75) were associated with preeclampsia.

CONCLUSION

 Provider trust, health locus of control, neighborhood violence, depression, and anxiety were associated with adverse pregnancy outcomes in Black women, independent of demographic and clinical risk factors.

KEY POINTS

· We identified associations between exposure to neighborhood violence and gestational age at birth.. · Trust, locus of control, depression, and anxiety were associated with preterm birth and preeclampsia.. · Future research should focus on interventions that address social and clinical factors..

Understanding the relationship between perceived discrimination, allostatic load, and all-cause mortality in US older adults: A mediation analysis

OBJECTIVE

To understand the relationship between perceived discrimination, allostatic load, and all-cause mortality; and to determine whether allostatic load is a mediator in the relationship between perceived discrimination and all-cause mortality among an older adult US population.

METHODS

Data from the Health and Retirement Study (2006-2012) was analyzed. Cox proportional hazard models were used to investigate the relationship between all-cause mortality and perceived discrimination, and all-cause mortality and allostatic load. Linear regression models were used to investigate the relationship between perceived discrimination and allostatic load. A mediation model with perceived discrimination and allostatic loads as independent variables was used to determine the association with all-cause mortality.

RESULTS

There were 5062 adults over the age of 50 included in the analysis. The relationship between perceived discrimination and allostatic load was statistically significant (b:0.14, [95%CI 0.10,0.19]; p < 0.001). The relationship between perceived discrimination and all-cause mortality was statistically significant (HR: 1.12, [95%CI 1.03,1.22]; p = 0.01). The relationship between allostatic load and all-cause mortality was statistically significant (HR: 1.11, [95%CI 1.08,1.13]; p < 0.001). The mediation model resulted in a decrease in hazard ratio and loss of statistical significance for perceived discrimination (HR: 1.09, [95%CI 0.98,1.21]; p = 0.13) when allostatic load (HR: 1.17, [95%CI 1.10,1.24]; p < 0.001) was added to the Cox regression model, indicating full mediation.

CONCLUSIONS

Allostatic load fully mediates the relationship between perceived discrimination and all-cause mortality. Understanding the role of allostatic load in this relationship provides an additional implication for screening and indications for tighter control of the modifiable components of allostatic load by healthcare providers, especially among individuals who experience discrimination.

Dose response relationship between food insecurity and quality of life in United States adults: 2016-2017

BACKGROUND

Food insecurity is associated with worse general health rating, but little research exists investigating whether there is a dose response relationship across levels of food security and mental and physical health domains at the population level.

METHODS

Data from the Medical Expenditure Panel Survey (2016-2017) with US adults aged 18 years and older was used. The physical component score (PCS) and mental component score (MCS) of Quality of Life, served as the outcome measures. Four categories of food insecurity (high, marginal, low, very low food security) served as the primary independent variable. Linear regression was used to run unadjusted followed by adjusted models. Separate models were run for PCS and MCS.

RESULTS

In a sample of US adults, 16.1% reported some degree of food insecurity. For PCS, marginal (β = - 2.54 (p < 0.001), low (β = - 3.41, (p < 0.001), and very low (β = - 5.62, (p < 0.001) food security was associated with worse PCS scores, compared to adults with high food security. For MCS, marginal (β = - 3.90 (p < 0.001), low (β = - 4.79, (p < 0.001), and very low (β = - 9.72, (p < 0.001) food security was associated with worse MCS scores, compared to adults with high food security.

CONCLUSION

Increasing levels of food insecurity were associated with decreased physical and mental health quality of life scores. This relationship was not explained by demographic factors, socioeconomic factors, insurance, or comorbidity burden. This study suggests work is needed to mitigate the impact of social risk, such as food insecurity, on quality of life in adults, and understand pathways and mechanisms for this relationship.

Relationship between mental health diagnoses and COVID-19 test positivity, hospitalization, and mortality in Southeast Wisconsin

BACKGROUND

There is a paucity of literature on the relationship between pre-existing mental health conditions and coronavirus disease-2019 (COVID-19) outcomes. The aim was to examine the association between pre-existing mental health diagnosis and COVID-19 outcomes (positive screen, hospitalization, mortality).

METHODS

Electronic medical record data for 30 976 adults tested for COVID-19 between March 2020 and 10th July 2020 was analyzed. COVID-19 outcomes included positive screen, hospitalization among screened positive, and mortality among screened positive and hospitalized. Primary independent variable, mental health disorders, was based on ICD-10 codes categorized as bipolar, internalizing, externalizing, and psychoses. Descriptive statistics were calculated, unadjusted and adjusted logistic regression and Cox proportional hazard models were used to investigate the relationship between each mental health disorder and COVID-19 outcomes.

RESULTS

Adults with externalizing (odds ratio (OR) 0.67, 95%CI 0.57-0.79) and internalizing disorders (OR 0.78, 95% CI 0.70-0.88) had lower odds of having a positive COVID-19 test in fully adjusted models. Adults with bipolar disorder had significantly higher odds of hospitalization in fully adjusted models (OR 4.27, 95% CI 2.06-8.86), and odds of hospitalization were significantly higher among those with externalizing disorders after adjusting for demographics (OR 1.71, 95% CI 1.23-2.38). Mortality was significantly higher in the fully adjusted model for patients with bipolar disorder (hazard ratio 2.67, 95% CI 1.07-6.67).

CONCLUSIONS

Adults with mental health disorders, while less likely to test positive for COVID-19, were more likely to be hospitalized and to die in the hospital. Study results suggest the importance of developing interventions that incorporate elements designed to address smoking cessation, nutrition and physical activity counseling and other needs specific to this population to improve COVID-19 outcomes.

Understanding the relationship between perceived discrimination and mortality in United States adults

OBJECTIVE

To understand the relationship between mortality and three types of perceived discrimination (lifetime, daily, chronic job) using a nationally representative sample of U.S. adults.

METHODS

Data from 4562 adults in the Midlife in the United States (MIDUS) between 2004 and 2006 (MIDUS II and MIDUS African American sample) were analyzed. Unadjusted associations between primary independent discrimination variables (lifetime, chronic job, daily) and mortality were analyzed using univariate Cox's proportional hazards regression models. Covariates were added to the models by group: predisposing (sex, age, race/ethnicity, education, marital status); enabling (household income, employment status, insurance status); and need factors (body mass index, diabetes, hypertension, stroke, cancer) to estimate hazard ratios.

RESULTS

After adjusting for all covariates, hazard ratios for lifetime discrimination (HR: 1.09, p = 0.034) and daily discrimination (HR: 1.03, p = 0.030) were statistically significant. There was no relationship between mortality and chronic job discrimination (HR:1.03, p = 0.15).

CONCLUSIONS

Adults experiencing lifetime and daily discrimination had significantly increased risk of mortality after adjusting for predisposing, enabling, and need factors. The findings highlight the importance of screening patients during clinical encounters for experiences of discrimination and providing appropriate resources to mitigate the negative impact of discriminatory events on mortality. Future research should work to fully understand the mechanism by which discrimination increases risk of mortality. These future findings should be used to develop targets for interventions designed to decrease mortality among adults who have experienced discrimination.

Contributions of social determinants of health to systolic blood pressure in United States adult immigrants: Use of path analysis to validate a conceptual framework

OBJECTIVE

Validate a conceptual framework and identify pathways between antecedent (life-course socioeconomic status (L-SES)), predisposing (age, sex, married, homeless as a child), enabling (health literacy, acculturation), and need (disability) social determinants of health (SDoH) and systolic blood pressure (SBP) in US immigrants.

METHODS

181 immigrants were enrolled in the study. Path analysis was used to identify paths by which SDoH influence SBP and to determine if antecedents, predisposing, enabling, and need factors have direct and indirect relationships with SBP.

RESULTS

The final model(chi2(5)=14.88, p = 0.011, RMSEA = 0.070, pclose = 0.17, CFI = 0.96) showed L-SES was directly associated with age (0.12, p = 0.019) and disability(0.17, p = 0.001); and indirectly associated with disability (0.29, p < 0.001) and SBP (0.31, p < 0.001). Age (0.31, p < 0.001) and sex(0.25, p < 0.001) were directly associated with SBP, and age was directly associated with disability (0.29, p < 0.001) and indirectly associated with SBP(0.14, p = 0.018). Other predisposing factors such as being married (-0.32, p < 0.001) and being homeless as a child alone (0.16, p < 0.001) were directly associated with disability and indirectly associated (0.14, p = 0.018) with SBP. Enabling factor of health literacy (0.16, p = 0.001) was directly associated with disability and indirectly associated (0.14, p = 0.018) with SBP. Need factor of disability (0.14, p = 0.018) was directly associated with SBP.

CONCLUSIONS

This study provides the first validation of a conceptual model for the relationship between SDoH and SBP among immigrants and identifies potential targets for focused interventions.

Mentoring strategies to support diversity in research-focused junior faculty: A scoping review

Objective

The purpose of this scoping review is two-fold: to assess the literature that quantitatively measures outcomes of mentorship programs designed to support research-focused junior faculty and to identify mentoring strategies that promote diversity within academic medicine mentoring programs.

Methods

Studies were identified by searching Medline using MESH terms for mentoring and academic medicine. Eligibility criteria included studies focused on junior faculty in research-focused positions, receiving mentorship, in an academic medical center in the USA, with outcomes collected to measure career success (career trajectory, career satisfaction, quality of life, research productivity, leadership positions). Data were abstracted using a standardized data collection form, and best practices were summarized.

Results

Search terms resulted in 1,842 articles for title and abstract review, with 27 manuscripts meeting inclusion criteria. Two studies focused specifically on women, and four studies focused on junior faculty from racial/ethnic backgrounds underrepresented in medicine. From the initial search, few studies were designed to specifically increase diversity or capture outcomes relevant to promotion within academic medicine. Of those which did, most studies captured the impact on research productivity and career satisfaction. Traditional one-on-one mentorship, structured peer mentorship facilitated by a senior mentor, and peer mentorship in combination with one-on-one mentorship were found to be effective strategies to facilitate research productivity.

Conclusion

Efforts are needed at the mentee, mentor, and institutional level to provide mentorship to diverse junior faculty on research competencies and career trajectory, create a sense of belonging, and connect junior faculty with institutional resources to support career success.

Effect of cognitive impairment on risk of death in Hispanic/Latino adults over the age of 50 residing in the United States with and without diabetes: Data from the Health and Retirement Study 1995-2014

OBJECTIVE

To understand the relationship between mortality and cognitive function among older US Hispanic adults with and without diabetes.

METHODS

Data from the Health and Retirement Study (1995-2014) were analyzed. Cox proportional hazard models were used to estimate the association between mortality and cognitive function. Models were stratified by diabetes.

RESULTS

Four thousand thirteen older US Hispanic adults were included. Fully adjusted models for individuals with diabetes showed those with mild cognitive impairment (MCI; hazard ratio [HR]: 1.61; 95% confidence interval [CI]: 1.06, 2.45; P = .025) and dementia (HR: 2.14; 95% CI: 1.25, 3.67; P = .006) had increased mortality compared to normal cognition. Fully adjusted models for individuals without diabetes showed those with MCI (HR: 1.87; 95% CI: 1.28, 2.74; P = .001) and dementia (HR: 3.25; 95% CI: 1.91, 5.55; P < .001) had increased mortality compared to normal cognition.

CONCLUSIONS

Cognitive impairment is associated with increased mortality in older US Hispanic adults with and without diabetes. Clinicians should regularly assess cognitive function in this group to quickly identify declines and make appropriate referrals for support to optimize health and reduce mortality.

Short-term impact of COVID-19 on quality of life, perceived stress, and serious psychological distress in an adult population in the midwest United States

PURPOSE

This study aimed to investigate changes over time in quality of life, perceived stress, and serious psychological distress for individuals diagnosed with COVID-19 in an urban academic health system.

METHODS

Phone-based surveys were completed with adult patients tested for COVID-19 during emergency department visits, hospitalizations, or outpatient visits at the Froedtert and Medical College of Wisconsin Health Network. Data were then matched to medical record data. Unadjusted and adjusted mixed effects linear models using random intercept were run for each outcome (physical health-related quality of life, mental health-related quality of life, perceived stress, and serious psychological distress) with time (baseline vs 3-month follow-up) as the primary independent variable. Individuals were treated as a random effect, with all covariates (age, sex, race/ethnicity, payor, comorbidity count, hospitalization, and intensive care unit (ICU) stay) treated as fixed effects.

RESULTS

264 adults tested positive for COVID-19 and completed baseline and 3-month follow-up assessments. Of that number, 31.8% were hospitalized due to COVID-19, and 10.2% were admitted for any reason to the ICU. After adjustment, patients reported higher physical health-related quality of life at 3 months compared to baseline (0.63, 95% CI 0.15, 1.11) and decreased stress at 3 months compared to baseline (- 0.85, 95% CI - 1.33, - 0.37). There were no associations between survey time and mental health-related quality of life or serious psychological distress.

CONCLUSIONS

Results suggest the influence of COVID-19 on physical health-related quality of life and stress may resolve over time, however, the influence of mental health on daily activities, work, and social activities may not.

Interventions to Reduce Hospital Readmissions in Older African Americans: A Systematic Review of Studies Including African American Patients

OBJECTIVES

This systematic review aims to summarize interventions that effectively reduced hospital readmission rates for African Americans (AAs) aged 65 and older.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed for this review. Studies were identified by searching PubMed for clinical trials on reducing hospital readmission among older patients published between 1 January 1990 and 31 January 2020. Eligibility criteria for the included studies were mean or median age ≥ 65 years, AAs included in the study, randomized clinical trial or quasi-experimental design, presence of an intervention, and hospital readmission as an outcome.

RESULTS

There were 5270 articles identified and 11 were included in the final review based on eligibility criteria. The majority of studies were conducted in academic centers, were multi-center trials, and included over 200 patients, and 6-90% of participants were older AAs. The length of intervention ranged from 1 week to over a year, with readmission assessed between 30 days and 1 year. Four studies which reported interventions that significantly reduced readmissions included both inpatient (e.g., discharge planning prior to discharge) and outpatient care components (e.g., follow-ups after discharge), and the majority used a multifaceted approach.

CONCLUSION

Findings from the review suggest successful interventions to reduce readmissions among AAs aged 65 and older should include inpatient and outpatient care components at a minimum. This systematic review showed limited evidence of interventions successfully decreasing readmission in older AAs, suggesting a need for research in the area to reduce readmission disparities and improve overall health.

Nonmedical Interventions For Type 2 Diabetes: Evidence, Actionable Strategies, And Policy Opportunities

This systematic review identified studies of nonmedical interventions designed to reduce risk for and improve clinical outcomes for type 2 diabetes. Specifically, this review sought to identify interventions that target structural racism and social determinants of health. To be included, studies were published in English; published between database initiation and January 2022; conducted in the United States; measured an intervention effect using a clinical trial, quasi-experimental, or pre-post design; included a population of adults at risk for or with type 2 diabetes; and targeted hemoglobin A1c levels, blood pressure, lipids, self-care, or quality of life as outcomes. The findings of our review indicate that interventions with targeted, multicomponent designs that combine both medical and nonmedical approaches can reduce risk for and improve clinical outcomes for type 2 diabetes. HbA1c levels improved significantly with the use of food supplementation with referral and diabetes support; the use of financial incentives with education and skills training; the use of housing relocation with counseling support; and the integration of nonmedical interventions into medical care using the electronic medical record. Our findings demonstrate that the literature on nonmedical interventions designed to address relevant social factors and target structural racism is limited. The article offers actionable strategies and identifies policy opportunities for targeting structural inequalities and decreasing social risk among adults with type 2 diabetes.

Trends in Healthcare Expenditures among Adults in the United States by Cancer Diagnosis Status, 2008-2016: A Cross Sectional Study

BACKGROUND

This study aims to assess trends in direct medical expenditures and indirect costs between adults with and without a prior cancer diagnosis from 2008-2016.

METHODS

Nine years of data (2008-2016) from the Medical Expenditure Panel Survey (weighted N=236,811,875) were used. The outcomes included medical expenditures (total expenditure, inpatient, office-based, medications, outpatient, dental, emergency room visits, home health, other) and health-related missed workdays. The predictor was prior cancer diagnosis. Covariates included demographic characteristics, comorbidities, and calendar year at time of survey completion. Two-part statistical modeling with a combination of binomial and positive distributions was used to estimate medical expenditures and missed workdays. Data were clustered into five timepoints: 2008-2009, 2010-2011, 2012-2013, 2014-2015, and 2016.

RESULTS

Eleven percent of the sample (n=25,005,230) had a prior cancer diagnosis. Compared to those without a prior cancer diagnosis, those with a prior cancer diagnosis had higher mean incremental total expenditures across all years. Between 2008-2016, the adjusted annual incremental total expenditures were $3,522 (95%CI $3,072, $3,972); office-based visits ($1,085;95% CI $990, $1180); inpatient hospitalizations ($810;95%CI $627, $992); outpatient appointments ($517;95%CI $434, $600); and medications ($409;95%CI $295, $523); and health-related missed workdays (0.75;95%CI 0.45, 1.04) compared to adults without a prior cancer diagnosis.

CONCLUSIONS

Adults with a prior cancer diagnosis had significantly increased healthcare expenditures and health-related missed workdays compared to those with no cancer diagnosis.

IMPACT

Our findings highlight the need for increasing strategies to remedy the impact of increasing direct and indirect costs associated with cancer survivorship as the population grows and ages.

Differences in the relationship between social capital and hypertension in emerging vs. established economies in Sub-Saharan Africa

Background

The global burden of hypertension is growing, particularly in low- and middle-income countries. This study aimed to investigate differences in the relationship between social capital and hypertension between regions in Sub-Saharan Africa (West vs. South Africa) and within regions (rural vs. urban residence within each country).

Methods

Data for 9,800 adults were analyzed from the Study on Global Ageing and Adult Health (SAGE) 2007-2010 for Ghana (West African emerging economy) and South Africa (South African established economy). Outcomes were self-reported and measured hypertension. The primary independent variable was social capital, dichotomized into low vs. medium/high. Interaction terms were tested between social capital and rural/urban residence status for each outcome by country. Linear and logistic regression models were run separately for both countries and each outcome.

Results

Those with low social capital in the emerging economy of Ghana were more likely to have hypertension based on measurement (OR=1.35, 95% CI=1.18,1.55), but the relationship with self-reported hypertension lost significance after adjustment. There was no significant relationship in the relationship between social capital and hypertension in the established economy of South Africa after adjustment. No significant interactions existed by rural/urban residence status in either country.

Conclusion

Low social capital was associated with worse hypertension outcomes, however, the relationship differed between South Africa and Ghana. Further investigation is needed to understand differences between and within countries to guide development of programs targeted at leveraging and promoting social capital as a positive component of overall health.

Manual therapy interventions in the management of adults with prior cervical spine surgery for degenerative conditions: a scoping review

Objective

Cervical spine surgeries for degenerative conditions are rapidly increasing. Cervical post-surgery syndrome consisting of chronic pain, adjacent segment disease, recurrent disc herniation, facet joint pain, and/or epidural scarring is common. Repeat surgery is regularly recommended, though patients are often unable to undergo or decline further surgery. Manual therapy is included in clinical practice guidelines for neck pain and related disorders, however clinical guidance for utilization of manual therapy in adults with prior cervical spine surgery is lacking. This study aimed to synthesize available literature and characterize outcomes and adverse events for manual therapy interventions in adults with prior cervical spine surgery due to degenerative conditions.

Methods

Preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews was followed. PubMed, Cumulative Index of Nursing and Allied Health Literature, physiotherapy evidence database, and Index to Chiropractic Literature were searched from inception through October 2021. English-language literature comprised of randomized clinical trials (RCT), case–control, cohort, and case report designs were included. Adults undergoing manual therapy, with or without combination of other interventions, with prior cervical spine surgery due to degenerative conditions were included.

Results

Twelve articles were identified, including 10 case reports, 1 low-quality RCT, and 1 acceptable-quality RCT. Eight case reports described 9 patients with history of fusion surgery. Two case reports described 2 patients with history of discectomy. One case report described one patient with separate operations of a discectomy at one level and a fusion at another level. One case report described 2 patients with history of cervical disc replacement surgery. The two RCTs included 63 and 86 participants, respectively. Use of manual joint mobilization/manipulation, table/instrument assisted mobilization/manipulation, and multimodal interventions were described in eligible studies. Favorable clinical outcomes were reported in 10 studies. Six case reports/series involving 8 patients described use of unclassified forms of manual therapy. Eight studies described the use of multimodal interventions along with manual therapy. One study described high patient satisfaction. Two studies, accounting for 3 patients, reported serious adverse events.

Conclusions

There is a lack of literature informing evidence related to clinical outcomes, patient satisfaction, and adverse events associated with manual therapy for patients with prior cervical spine surgery due to degenerative conditions. High-quality studies of higher-level hierarchical study design are needed to understand the clinical utility and safety profile of manual therapy for this population.

Explanatory role of sociodemographic, clinical, behavioral, and social factors on cognitive decline in older adults with diabetes

BACKGROUND

The aim of the study was to examine the explanatory role of sociodemographic, clinical, behavioral, and social factors on racial/ethnic differences in cognitive decline among adults with diabetes.

METHODS

Adults aged 50+ years with diabetes from the Health and Retirement Survey were assessed for cognitive function (normal, mild cognitive impairment [MCI], and dementia). Generalized estimating equation (GEE) logistic regression models were used to account for repeating measures over time. Models were adjusted for sociodemographic (gender, age, education, household income and assets), behavioral (smoking), clinical (ie. comorbidities, body mass index), and social (social support, loneliness, social participation, perceived constraints and perceived mastery on personal control) factors.

RESULTS

Unadjusted models showed non-Hispanic Blacks (NHB) and Hispanics were significantly more likely to progress from normal cognition to dementia (NHB OR: 2.99, 95%CI 2.35-3.81; Hispanic OR: 3.55, 95%CI 2.77-4.56), and normal cognition to MCI (NHB OR = 2.45, 95%CI 2.14-2.82; Hispanic OR = 2.49, 95%CI 2.13-2.90) compared to non-Hispanic Whites (NHW). Unadjusted models for the transition from mild cognitive decline to dementia showed Hispanics were more likely than NHW to progress (OR = 1.43, 95%CI 1.11-1.84). After adjusting for sociodemographic, clinical/behavioral, and social measures, NHB were 3.75 times more likely (95%CI 2.52-5.56) than NHW to reach dementia from normal cognition. NHB were 2.87 times more likely (95%CI 2.37-3.48) than NHW to reach MCI from normal. Hispanics were 1.72 times more likely (95%CI 1.17-2.52) than NHW to reach dementia from MCI.

CONCLUSION

Clinical/behavioral and social factors did not explain racial/ethnic disparities. Racial/ethnic disparities are less evident from MCI to dementia, emphasizing preventative measures/interventions before cognitive impairment onset are important.

Prevalence and sociodemographic correlates of diabetes among adults in Namibia and South Africa

OBJECTIVE

The aims of this study were to understand the prevalence and sociodemographic characteristics associated with diabetes among adults in Namibia and South Africa.

METHODS

Data from the Demographic and Health Survey for Namibia (2013) and South Africa (2016) were analyzed. The dependent variable, diabetes, was defined using lab values for blood glucose≥ 126 for Namibia, and hemoglobin A1c (HbA1c) ≥ 6.5% for South Africa. Logistic regression was used to identify independent correlates of diabetes for each country. Demographic (age, sex, geographic location, number of children), economic (wealth index, education level), and cultural (religion - Namibia, ethnicity - South Africa) factors were added in blocks to the models.

RESULTS

In Namibia, 4.6% had diabetes based on blood glucose, and 14.6% had diabetes based on HbA1c in South Africa. In Namibia, after adjustment, higher wealth was independently associated with diabetes (OR:1.67; 95% CI: 1.11, 2.50). In South Africa, after adjustment, those who were older (OR: 1.06; 95% CI: 1.04, 1.07), female (OR: 1.25; 95% CI: 1.03, 1.52), lived in a rural area (OR: 1.54; 95% CI: 1.20, 1.96), and Black (OR: 2.27; 95% CI: 1.17, 4.42) or Other (OR: 5.74; 95% CI: 2.50, 13.20) compared to White, had increased odds of diabetes.

CONCLUSIONS

Prevalence of diabetes is high in South Africa and relatively low in Namibia using reliable laboratory diagnostic indices. Strategies to address the rising burden of non-communicable diseases like diabetes are needed in sub-Saharan Africa.

HOME DM-BAT: home-based diabetes-modified behavioral activation treatment for low-income seniors with type 2 diabetes-study protocol for a randomized controlled trial

BACKGROUND

About 13% of African Americans and 13% of Hispanics have diabetes, compared to 8% of non-Hispanic Whites (NHWs). This is more pronounced in the elderly where about 25-30% of those aged 65 and older have diabetes. Studies have found associations between social determinants of health (SDoH) and increased incidence, prevalence, and burden of diabetes; however, few interventions have accounted for the context in which the elderly live by addressing SDoH. Specifically, psychosocial factors (such as cognitive dysfunction, functional impairment, and social isolation) impacting this population may be under-addressed due to numerous medical concerns addressed during the clinical visit. The long-term goal of the project is to identify strategies to improve glycemic control and reduce diabetes complications and mortality in African Americans and Hispanics/Latinos with type 2 diabetes.

METHODS

This is a 5-year prospective, randomized clinical trial, which will test the effectiveness of a home-based diabetes-modified behavioral activation treatment for low-income, minority seniors with type 2 diabetes mellitus (T2DM) (HOME DM-BAT). Two hundred, aged 65 and older and with an HbA1c ≥8%, will be randomized into one of two groups: (1) an intervention using in-home, nurse telephone-delivered diabetes education, and behavioral activation or (2) a usual care group using in-home, nurse telephone-delivered, health education/supportive therapy. Participants will be followed for 12 months to ascertain the effect of the intervention on glycemic control, blood pressure, and low-density lipoprotein (LDL) cholesterol. The primary hypothesis is low-income, minority seniors with poorly controlled type 2 diabetes randomized to HOME DM-BAT will have significantly greater improvements in clinical outcomes at 12 months of follow-up compared to usual care.

DISCUSSION

Results from this study will provide important insight into the effectiveness of a home-based diabetes-modified behavioral activation treatment for low-income, minority seniors with uncontrolled type 2 diabetes mellitus and inform strategies to improve glycemic control and reduce diabetes complications in minority elderly with T2DM.

The Relationship Between Patient Satisfaction and Healthcare Expenditures in Adults with Spine Related Disorders: An Analysis of the 2008 to 2015 Medical Expenditures Panel Survey (MEPS)

STUDY DESIGN

Cross-sectional study.

OBJECTIVE

The aim of this study was to investigate the relationship between patient satisfaction (PS) and healthcare expenditures (HCE) in adults with spine related disorders (SRDs).

SUMMARY OF BACKGROUND DATA

SRDs are widespread and pose a high cost to society. PS and HCE have yet to be studied in this population.

METHODS

Fifteen thousand eight hundred fifty adults with SRDs from the Medical Expenditures Panel Survey (MEPS) (2008-2015) were analyzed. The MEPS medical conditions files were used to identify SRDs based on International Classification of Diseases-9 codes. Frequencies and percentages of sample demographics were calculated. HCE was measured as total direct payments for care provided during the survey year. A composite PS score was constructed using a 0 to 10 rating of their healthcare providers combined with the frequency in which patients felt they were listened to, were given understandable explanations, were respected, and were given enough time. Mean unadjusted HCE were calculated for each year and by quartile of PS. A two-part model consisting of a probit model and subsequent generalized linear model with gamma distribution was performed, adjusting for relevant covariates. Margins command was used to calculate incremental estimates of HCE.

RESULTS

Mean unadjusted HCE increased annually from $7057 (95% confidence interval [CI], $6516, $7597) in 2008 to $9820 (95% CI, $8811, $10,830) in 2015 for adults with SRDs. Adjusting for predisposing factors, individuals in second, third, and fourth quartiles of PS were significantly different from the first quartile. Adjusting for predisposing and enabling factors, only fourth quartile was significantly different from first quartile. After adjusting for predisposing, enabling and need factors, second, third, and fourth quartiles were no longer significantly different from the first quartile.

CONCLUSION

Expenditures have increased over time in adults with SRDs. PS is significantly associated with expenditures after controlling for predisposing and enabling factors, but not significant after controlling for need factors. Need factors appear to explain the relationship between lower levels of PS and higher HCE in adults with SRDs.Level of Evidence: 2.

The Relationship Between Immigration Status and Chronic Kidney Disease Risk Factors in Immigrants and US-Born Adults

Objective:

To understand the relationship between nativity and measures of kidney function including estimated glomerular filtration rate (eGFR) and albumin-to-creatinine ratio (ACR).

Methods:

Seven waves of data from the National Health and Nutrition Examination Survey (2001 – 2014) was analyzed. General linear regression methods were used to assess the relationship between eGFR, ACR and nativity (foreign-born vs US-born). Models were adjusted for length of time in the US, demographic variables, comorbidities, lifestyle factors, and access to healthcare.

Results:

There were 27,111 individuals representing 217,842,257 US adults included in the study. Approximately 26.1% were immigrants, with 40.4% of immigrants having resided <15 years in the US. Among immigrants with <15 years of residence, 51% were Hispanic, and 54.4% had high school or below education. After controlling for demographics and length of time in the US, immigrants were 26% more likely to have an ACR >= 30mg/g (OR=1.26, 95% CI: 1.08 – 1.47); however, after controlling for demographics, length of time, comorbidities, and lifestyle factors the results were no longer significant. Immigrants were significantly less likely to have an eGFR < 60 (OR=0.42, 95%CI: 0.36 – 0.50), which remained after adjustment (OR=0.75, 95%CI: 0.61 – 0.93).

Conclusions:

Immigrants had significantly lower odds of having an eGFR < 60 compared to US-born adults. Additionally, immigrants with >= 15 years in the US had mean eGFR values that were less than immigrants < 15 years in the US, indicating that there is some decrease in kidney function as the length of US residence increases.

Trends in Food Insecurity in the United States from 2011-2017: Disparities by Age, Sex, Race/Ethnicity, and Income

The number of individuals in the United States who report food insecurity doubled between 2005 and 2012, with little research investigating possible disparities across time in food-insecure populations. The aim of this study was to investigate trends in food insecurity between 2001-2017 by sex, race/ethnicity, income, and age. Adults participating in the National Health Interview Survey (NHIS) between 2011-2017 were included in the study. Food insecurity was dichotomized based on affirmative responses to the Food Security Survey Module. Statistical analysis included logistic regression to investigate trends in food insecurity over time by each demographic variable (age, sex, race/ethnicity, income) adjusted by survey year and demographic variables. After adjustment, those ages ≥65 years were 39% less likely (OR = 0.61, 95% CI [0.57,0.65]) to report food insecurity compared to those ages 18-34; females were 23% more likely to be food insecure than males (OR = 1.23, 95% CI [1.19,1.27]); non-Hispanic blacks were 1.7 times more likely (OR = 1.69, 95% CI [1.62,1.76]) to be food insecure than non-Hispanic whites; and a clear gradient existed by income, with lower incomes more likely to be food insecure. Disparities in food insecurity exist across age, race/ethnicity, sex, and income and were consistent over time. These results suggest that targeted programs may be necessary to decrease food insecurity in particularly vulnerable subpopulations, and barriers to access and use of existing programs need to be investigated.

HIV and cardiovascular disease in sub-Saharan Africa: Demographic and Health Survey data for 4 countries

Background

Investigate the relationship between two common cardiovascular diseases and HIV in adults living in sub-Saharan Africa using population data provided through the Demographic and Health Survey.

Methods

Data for four sub-Saharan countries were used. All adults asked questions regarding diagnosis of HIV, diabetes, and hypertension were included in the sample totaling 5356 in Lesotho, 3294 in Namibia, 9917 in Senegal, and 1051 in South Africa. Logistic models were run for each country separately, with self-reported diabetes as the first outcome and self-reported hypertension as the second outcome and HIV status as the primary independent variable. Models were adjusted for age, gender, rural/urban residence and BMI. Complex survey design allowed weighting to the population.

Results

Prevalence of self-reported diabetes ranged from 3.8% in Namibia to 0.5% in Senegal. Prevalence of self-reported hypertension ranged from 22.9% in Namibia to 0.6% in Senegal. In unadjusted models, individuals with HIV in Lesotho were 2 times more likely to have self-reported diabetes (OR = 2.01, 95% CI 1.08–3.73), however the relationship lost significance after adjustment. Individuals with HIV were less likely to have self-reported diabetes after adjustment in Namibia (OR = 0.29, 95% CI 0.12–0.72) and less likely to have self-reported hypertension after adjustment in Lesotho (OR = 0.63, 95% CI 0.47–0.83). Relationships were not significant for Senegal or South Africa.

Discussion

HIV did not serve as a risk factor for self-reported cardiovascular disease in sub-Saharan Africa during the years included in this study. However, given the growing prevalence of diabetes and hypertension in the region, and the high prevalence of undiagnosed cardiovascular disease, it will be important to continue to track and monitor cardiovascular disease at the population level and in individuals with and without HIV.

Conclusions

The odds of self-reported diabetes in individuals with HIV was high in Lesotho and low in Namibia, while the odds of self-reported hypertension in individuals with HIV was low across all 4 countries included in this study. Programs are needed to target individuals that need to manage multiple diseases at once and should consider increasing access to cardiovascular disease management programs for older adults, individuals with high BMI, women, and those living in urban settings.

Team Science, Population Health, and COVID-19: Lessons Learned Adapting a Population Health Research Team to COVID-19

Our multidisciplinary research team is composed of 6 faculty with expertise in internal medicine, nephrology, maternal/fetal medicine, health services research, statistics, and community-based research, and 36 program staff including biostatisticians, nurses, program coordinators, program assistants, and medical assistants/phlebotomists. With the emergence of the COVID-19 pandemic and the impact it was having on our community, especially the ethnic minority population in inner-city Milwaukee, we felt it was critical to stay engaged and figure out how to ask meaningful research questions that are important to the community, are relevant to the times, and will lead to lasting change. While navigating this unprecedented challenge, our research team made difficult decisions but were able to engage our staff and respond to community needs. We organized our lessons learned to serve as a perspective on how to effectively remain committed to vision and serve our communities, while collecting evidence that can inform policy in difficult times.

AKI in Hospitalized Patients with COVID-19 and Seasonal Influenza: A Comparative Analysis

Background

Coronavirus disease 2019 (COVID-19) is often compared with seasonal influenza and the two diseases have similarities, including the risk of systemic manifestations such as AKI. The aim of this study was to perform a comparative analysis of the prevalence, risk factors, and outcomes of AKI in patients who were hospitalized with COVID-19 and influenza.

Methods

Retrospective cohort study of patients who were hospitalized with COVID-19 (n=325) or seasonal influenza (n=433). AKI was defined by Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Baseline characteristics and hospitalization data were collected, and multivariable analysis was performed to determine the independent predictors for AKI.

Results

AKI occurred in 33% of COVID-19 hospitalizations (COV-AKI) and 33% of influenza hospitalizations (FLU-AKI). After adjusting for age, sex, and comorbidity count, the risk of stage 3 AKI was significantly higher in COV-AKI (OR, 3.46; 95% CI, 1.63 to 7.37). Pre-existing CKD was associated with a six- to seven-fold increased likelihood for FLU-AKI and COV-AKI. Mechanical ventilation was associated with a higher likelihood of developing AKI in the COVID-19 cohort (OR, 5.85; 95% CI, 2.30 to 15.63). Black race, after adjustment for comorbidities, was an independent risk for COV-AKI.

Conclusions

Pre-existing CKD was a major risk factor for AKI in both cohorts. Black race (independent of comorbidities) and mechanical ventilation were associated with a higher risk of developing COV-AKI, which is characterized by a higher burden of stage 3 AKI and overall poorer prognosis.

Using a Diabetes Risk Score to Identify Patients Without Diabetes at Risk for New Hyperglycemia in the Hospital

OBJECTIVE

To assess the value of a validated diabetes risk test, the Cambridge Risk Score (CRS), to identify patients admitted to hospital without diabetes at risk for new hyperglycemia (NH).

METHODS

This retrospective cross-sectional study included adults admitted to a hospital over a 4-year period. Patients with no diabetes diagnosis and not on antidiabetics were included. The CRS was calculated for each patient, and those with available glycated hemoglobin (HbA1C) results were investigated in a second analysis. Multivariate regression analyses were performed to assess the association among CRS, HbA1C, and the risk for NH.

RESULTS

A total of 19,830 subjects comprised the sample, of which 38% were found to have developed NH, defined as a blood glucose level ≥140 mg/dL. After accounting for covariates, the CRS was significantly associated with NH (odds ratio [OR], 1.19 [1.16, 1.22]; P < .001). Only 17% of patients had their HbA1C values checked within 6 months of admission. Compared with patients without diabetes, patients with prediabetes based on their HbA1C level (OR, 1.59 [1.37, 1.86]; P < .001) and patients with undiagnosed diabetes (OR, 5.95 [3.50, 10.65]; P < .001) were also significantly more likely to have NH.

CONCLUSION

Results of this study show that the CRS and HbA1C levels were significantly associated with the risk of developing NH in inpatient adults without diabetes. Given that an HbA1C level was missing in most medical records of hospitalized patients without diabetes, the CRS could be a useful tool for early identification and management of NH, possibly leading to better outcomes.

Age and Gender Differences in Trends and Impact of Depression on Quality of Life in the United States, 2008 to 2016

BACKGROUND

We aimed to examine age and gender differences in the relationship between depression and quality of life among United States adults.

METHODS

Medical Expenditure Panel Survey data for 2008 to 2016 on 227,663 adults were analyzed. The dependent variable, quality of life, included physical component summary scores and mental component summary scores from the Short Form Health Survey. The key independent variable, depression, was measured using the two-item Patient Health Questionnaire. General linear regression models examined the relationship between quality of life and depression. Models were adjusted for individual and environmental characteristics, symptom status, functional and biological status, and health perceptions and were stratified by gender and age.

RESULTS

In adjusted models, mental component summary scores were significantly lower among those with depression compared with those without depression (β = -0.39; 95% confidence interval [CI], 0.38 to -1.16) and lower among women compared with men (β = -0.10; 95% CI, 0.10 to -1.31). Models stratified by gender and age found women with depression ages 40 to 64 (β = -0.07; 95% CI, 0.07 to -0.20) and 65 or older (β = -0.08; 95% CI, 0.08 to -0.24) had significantly lower physical component summary scores compared with those without depression. Among men with depression, those ages 18 to 39 (β = -0.03; 95% CI, 0.03 to -0.10) and 40 to 64 (β = -0.09, 95% CI, 0.08 to -0.26) had lower physical component summary scores compared with those without depression. Women and men of all ages with depression had significantly lower mental component summary scores compared with those without depression.

CONCLUSIONS

Public health interventions and clinical approaches to address depression in women and men should target functional status in men and perceptions of health in women.

Cost-effectiveness of financial incentives to improve glycemic control in adults with diabetes: A pilot randomized controlled trial

Purpose

Determine the cost-effectiveness of three financial incentive structures in obtaining a 1% within group drop in HbA1c among adults with diabetes.

Methods

60 African Americans with type 2 diabetes were randomized to one of three financial incentive structures and followed for 3-months. Group 1 (low frequency) received a single incentive for absolute HbA1c reduction, Group 2 (moderate frequency) received a two-part incentive for home testing of glucose and absolute HbA1c reduction and Group 3 (high frequency) received a multiple component incentive for home testing, attendance of weekly telephone education classes and absolute HbA1c reduction. The primary clinical outcome was HbA1c reduction within each arm at 3-months. Cost for each arm was calculated based on the cost of the intervention, cost of health care visits during the 3-month time frame, and cost of workdays missed from illness. Incremental cost effectiveness ratios (ICER) were calculated based on achieving a 1% within group drop in HbA1c and were bootstrapped with 1,000 replications.

Results

The ICER to decrease HbA1c by 1% was $1,100 for all three arms, however, bootstrapped standard errors differed with Group 1 having twice the variation around the ICER coefficient as Groups 2 and 3. ICERs were statistically significant for Groups 2 and 3 (p<0.001) indicating they are cost effective interventions.

Conclusions

Given ICERs of prior diabetes interventions range from $1,000-$4,000, a cost of $1,100 per 1% within group decrease in HbA1c is a promising intervention. Multi-component incentive structures seem to have the least variation in cost-effectiveness.

Relationship between physical and mental health comorbidities and COVID-19 positivity, hospitalization, and mortality

BACKGROUND

Understanding the association between separate and combined mental and physical health diagnoses and COVID-19 outcomes is greatly needed to address the severity of illness.

METHODS

Data on 24,034 patients screened for COVID-19 as of July 2020 were extracted from the Froedtert/Medical College of Wisconsin Epic medical record. COVID-19 outcomes were defined as positive screens, proportion hospitalized among positive screens, and proportion that died among positive and hospitalized population. The primary independent variable was a 3-category variable: physical health diagnosis alone, mental health diagnosis alone, and combined mental and physical health diagnoses. Logistic regression and Cox proportional hazard models were used to examine the independent relationship between separate and combined diagnoses and COVID-19 outcomes.

RESULTS

Compared to physical health diagnosis alone, mental health diagnosis alone had lower odds of screening positive (OR=0.68, CI=0.51;0.92) and was not associated with hospitalization or mortality among positive screens. Combined had lower odds of screening positive (OR=0.78, CI=0.69;0.88) and higher odds of hospitalization among positive screens after adjusting for demographics (OR=1.58, CI=1.20;2.08) but lost significance in the fully adjusted model. No category of diagnoses was associated with mortality.

LIMITATIONS

Analysis is cross-sectional and cannot speak to any causal relationships.

CONCLUSIONS

Overall, compared to physical health diagnosis alone, mental health diagnosis and combined had lower odds of positive screens. However, individuals with combined were more likely to be hospitalized, after adjusting for demographics only. These findings add new evidence for risk of COVID-19 and related hospitalization in individuals who have a physical and mental health diagnosis.

Association between Health and Wealth among Kenyan Adults with Hypertension

Background:

This paper examines the relationship between hypertension and wealth in a national sample of Kenyan adults.

Methods:

Data from 27,552 individuals from the Demographic and Health Survey Program (DHS) for Kenya were analyzed. Wealth index, a cumulative measure of household standard of living, was the outcome. The final analysis was stratified by gender with covariates added in blocks (demographics, economic, and cultural) to investigate the independent association of hypertension with wealth index.

Results:

Approximately 7.6% of those with hypertension had a wealth index above the median. For women and men, hypertension was significantly associated with higher wealth index (women ß=0.26; CI=0.19; 0.34; men ß=0.36; CI=0.19; 0.53). After adjusting for age, rural location, children, employment, education, ethnicity, and religion, hypertension maintained statistical significance with wealth index for both women and men (women ß=0.06; CI=0.01; 0.11; men ß=0.20; CI=0.08; 0.31).

Conclusions:

As Kenya as a nation undergoes health care reform while also experiencing a high burden of hypertension, the results presented here provide preliminary evidence that may be used in support for decision makers for the wealth effects of health interventions. Additional work is needed to understand the longitudinal relationship between hypertension and wealth at the national level.

Association between pregestational diabetes and mortality among appropriate-for-gestational age birthweight infants

BACKGROUND/OBJECTIVE

Existing studies have shown that pregestational diabetes is a significant risk factor for adverse birth outcomes. However, it is unclear, whether pregestational diabetes and neonatal birthweight that is appropriate for the gestational age (AGA), a proxy for overall adequate glycemic control, is associated with higher infant mortality. To address this controversy, this study investigated the relationship between pregestational diabetes and infant mortality in appropriate-for-gestational age infants in the United States.

METHODS

Data from the National Vital Statistics System-Linked Birth-Infant Death dataset, including 6,962,028 live births between 2011 and 2013 were analyzed. The study was conducted in the US and data were analyzed in Milwaukee, Wisconsin. The outcome was mortality among AGA newborns, defined as annual deaths per 1000 live births with birthweights between the 10th and 90th percentiles for gestational age delivering at ≥37 weeks. The exposure was pregestational diabetes. Covariates were maternal demographics, behavioral/clinical, and infant factors. Logistic regression was used with p values <.05 considered statistically significant.

RESULTS

A total of 6,962,028 live births met inclusion criteria. Of these, a total of 11,711 (1.0%) term AGA birthweight infants died before their first birthday. About 35,689 (0.5%) mothers were diagnosed with pregestational diabetes prior to pregnancy with 0.3% of infants whose mothers had diabetes dying in their first year of life. In the unadjusted model, pregestational diabetes had a significant association with increased odds of mortality in term AGA infants (OR: 1.9, 95% CI: 1.6 - 2.3). AGA mortality remained significantly higher for women with pregestational diabetes compared to controls, after adjusting for maternal demographics (OR: 1.9, 95% CI: 1.6-2.3), behavioral/clinical characteristics (OR: 1.6, 95% CI: 1.3-2.0), and infant factors (OR: 1.3, 95% CI: 1.1-1.6).

CONCLUSIONS

In term pregnancies, pregestational diabetes was significantly associated with 30% higher mortality among AGA birthweight infants. Our study is innovative in its focus on AGA infants that overall is associated with good maternal glycemic control during pregnancy and in theory should confer a risk for infant mortality that is similar to pregnancies not complicated by pregestational diabetes. Despite this, we still found that even term AGA infants have higher risk of mortality in the setting of maternal pregestational diabetes. Implications of our findings underscore the importance of close antepartum surveillance and optimization of glycemic control preconception, identification of treatment targets, and health policies to reduce infant mortality. The results from this study may assist other researchers and clinicians understand how best to target future interventions to reduce term infant mortality and the burden of pregestational diabetes in the United States.

Financial incentives to improve glycemic control in African American adults with type 2 diabetes: a pilot randomized controlled trial

Background

Financial incentives is emerging as a viable strategy for improving clinical outcomes for adults with type 2 diabetes. However, there is limited data on optimal structure for financial incentives and whether financial incentives are effective in African Americans with type 2 diabetes. This pilot study evaluated impact of three financial incentive structures on glycemic control in this population.

Methods

Sixty adults with type 2 diabetes were randomized to one of three financial incentive structures: 1) single incentive (Group 1) at 3 months for Hemoglobin A1c (HbA1c) reduction, 2) two-part equal incentive (Group 2) for home testing of glucose and HbA1c reduction at 3 months, and 3) three-part equal incentive (Group 3) for home testing, attendance of weekly telephone education classes and HbA1c reduction at 3 months. The primary outcome was HbA1c reduction within each group at 3 months post-randomization. Paired t-tests were used to test differences between baseline and 3-month HbA1c within each group.

Results

The mean age for the sample was 57.9 years and 71.9% were women. Each incentive structure led to significant reductions in HbA1c at 3 months with the greatest reduction from baseline in the group with incentives for multiple components: Group 1 mean reduction = 1.25, Group 2 mean reduction = 1.73, Group 3 mean reduction = 1.74.

Conclusion

Financial incentives led to significant reductions in HbA1c from baseline within each group. Incentives for multiple components led to the greatest reductions from baseline. Structured financial incentives that reward home monitoring, attendance of telephone education sessions, and lifestyle modification to lower HbA1c are viable options for glycemic control in African Americans with type 2 diabetes.

Trends in prevalence of depression and serious psychological distress in United States immigrant and non-immigrant populations, 2010 - 2016

OBJECTIVE

To examine the prevalence of depression and serious psychological distress (SPD) among adult United States (US) immigrants and US-born; and to investigate trends in depression and SPD.

METHODS

National Health Interview Survey data (2010 - 2016) was analyzed. Chi-square tests were used to measure differences in prevalence of SPD between US-born and immigrants, and differences in prevalence of depression. Logistic regression models were used to measure the association between mental health outcomes (depression, SPD) and predictors (nativity, length of residence). General linear models were used to investigate depression and SPD trends.

RESULTS

101,142 US adults were included in the analysis. Immigrants were found to be 11% (OR 0.89, 95% CI [0.85,0.95]) less likely to suffer from depression compared to US-born. US-born (p<0.0001) had a higher prevalence of depression compared to immigrants, and prevalence of depression decreased overtime (p=0.011) for immigrants and US-born individuals. Immigrants who lived in the US 15+ years were 17% (OR 1.17, 95% CI [1.00,1.36]) more likely to have SPD compared to those who were born in the US. Among immigrants, as length of residence increased the prevalence of SPD (p=0.002) and depression (p<0.0001) increased.

LIMITATIONS

This study examines immigrants as an entire population, not accounting for differences in immigrant status or immigrant ethnicity.

CONCLUSIONS

While the prevalence of depression is lower in immigrants compared to US-born, being an immigrant in the US for more than 15 years increases risk of SPD to the point of surpassing that of US-born individuals and increases risk of depression.

Trends in Medical Expenditures by Race/Ethnicity in Adults with Type 2 Diabetes 2002-2011

OBJECTIVE

The objective of the study was to examine racial/ethnic differences in medical expenditures (prescription, office-based, in-patient, out-patient, emergency room, total) over time, overall and by type of expenditure, in a nationally representative sample of adults with diabetes.

METHODS

A weighted sample of 17,820,243 adults aged ≥18 with diabetes from the Medical Expenditure Panel Survey (MEPS) dataset from 2002 to 2011 were analyzed for this study. Multiple comparison testing and general linear model (GLM) were used to test for differences in expenditures by race. Total unadjusted expenditures by racial/ethnic category stratified by different insurance categories (privately insured, publicly insured, uninsured and overall) were also estimated.

RESULTS

Non-Hispanic Whites (NHW) had more than $4000 higher expenditures than Hispanics and Other races (p < 0.0001). Prescription costs were about $410 less for Non-Hispanic Blacks (NHB) (p < 0.0001), and more than $600 less for Hispanics (p < 0.0001) and Others (p < 0.0001) compared to NHW.

CONCLUSION

Minority groups with type 2 diabetes were found to have significantly less total expenditures, with the exception of total expenditures for NHB compared to NHW. These findings indicate minorities with type 2 diabetes may be receiving less care than NHW, which has implications for the known disparities in health outcomes and complications in individuals with diabetes.

Examining racial and ethnic trends and differences in annual healthcare expenditures among a nationally representative sample of adults with arthritis from 2008 to 2016

BACKGROUND

Disparities in health care utilization and outcomes for racial and ethnic minorities with arthritis are well-established. However, there is a paucity of research on racial and ethnic differences in healthcare expenditures and if this relationship has changed over time. Our objectives were to: 1) examine trends in annual healthcare expenditures for adults with arthritis by race and ethnicity, and 2) determine if racial and ethnic differences in annual healthcare expenditures were independent of other factors such as healthcare access and functional disability.

METHODS

We used the Medical Expenditures Panel Survey (2008-2016) to examine trends in annual healthcare expenditures within and between racial and ethnic groups with arthritis (n = 227,663). A two-part model was used to estimate the marginal differences in expenditures by race and ethnicity after adjusting for relevant covariates, including the impact of healthcare access.

RESULTS

Between 2008 and 2016, there were no significant changes in unadjusted healthcare expenditures within any of the racial and ethnic groups, but the trend among non-Hispanic whites did differ significantly from Hispanics and Other. In fully adjusted analysis, mean annual expenditures for non-Hispanic whites was $946, $939, and $1178 more than non-Hispanic blacks, Hispanics, and Other, respectively (p < .001). Healthcare access also independently explained expenditure differences in this population with adults who delayed care spending significantly more ($2629) versus those who went without care spending significantly less (-$1591).

CONCLUSIONS

Race and ethnicity are independent drivers of healthcare expenditures among adults with arthritis independent of healthcare access and functional disability. This underscores the need for ongoing research on the factors that influence persistent racial and ethnic differences in this population.

Examination of the Association Between Latent Variables for Social Determinants of Health and Blood Pressure Control in Immigrants using Structural Equation Modeling

BACKGROUND

Hypertension is responsible for about 12.8% of deaths around the world. Immigrants' risk of developing hypertension increases with length of residency. There is limited work on the role of social determinants of health and blood pressure control in immigrants. We created a theory-based conceptual model for immigrant-specific and general social determinants variables and their relationship to blood pressure.

PURPOSE

Use a theory-based model to identify latent variables for immigrant-specific social determinants using confirmatory factor analysis (CFA) and structural equation modeling (SEM) to test theoretical validity and relationship with blood pressure (BP).

METHODS

CFA was used to identify latent variables for global socioeconomic status, stressors of immigration, adaptation to immigration, acculturation, and burden of disease. SEM was used to test the structural relationships between latent variables and BP.

RESULTS

181 immigrants were included in the analysis. The final model (chi2 (68, n = 181) = 149.87, p < 0.001, RMSEA = 0.055, CFI = 0.94, TLI = 0.91, CD = 0.99) found burden of disease was significantly related to BP (r = 0.35, p < 0.001).

CONCLUSIONS

One latent variable measuring need was significantly associated with BP in an immigrant sample. This suggests that interventions targeting burden of disease are likely to be effective in controlling blood pressure in immigrants.

Telehealth and indigenous populations around the world: a systematic review on current modalities for physical and mental health

Approximately 370-500 million Indigenous people live worldwide. While Indigenous peoples make up only 5% of the world's population, they account for 15% of the extreme poor and have life expectancy that is 20 years shorter than that of non-Indigenous people. Access to healthcare has been identified as an important social determinant of health and key driver of health outcomes. Indigenous populations often face barriers to accessing healthcare including living in remote areas, lacking financial resources, and having cultural differences. Telehealth, the utililzation of any synchronous modality, including phone, video, or teleconferencing technology used to support the provision of long-distance health care and health education, is a feasible and cost-effective treatment delivery mechanism that has successfully addressed access barriers faced by vulnerable populations globally, however, few studies have included indigenous populations and the application of this technology to improve physical and mental health outcomes. This systematic review aims to identify trials that were conducted among Indigenous adults, and to summarize the components of interventions that have been found to effectively improve the health of Indigenous peoples. The PRISMA guidelines for reporting of systematic reviews were followed in preparing this manuscript. Studies were identified by searching PubMed, Scopus, and PsychInfo databases for clinical trial articles on Indigenous peoples and mental and physical health, published between January 1, 1998 and December 31, 2018. Eligibility criteria for determining studies to include in the analysis were as follows: (I) ≥18 years of age; (II) indigenous peoples; (III) any technology-based intervention; (IV) studies included at least one of the following mental health (depression, post-traumatic stress disorder, suicide) and physical health (mortality, blood pressure, hemoglobin A1C, cholesterol, quality of life) outcomes; (V) clinical trials. A total of 2,662 articles were identified and six were included in the final review based on pre-specified eligibility criteria. Three were conducted in the United States, one study was conducted in Canada, and two were conducted in New Zealand. Study sample sizes ranged from 20 to 762, intervention delivery times ranged from three to 20 months and utilized telephone, internet and SMS messaging as the type of technology. There is a paucity of evidence on the use of telehealth programs to increase access to chronic disease programs in Indigenous populations. This review highlights the importance of culturally tailoring programs despite the modality in which they are delivered, and recommends telephone-based delivery facilitated by a trained health professional. Telehealth has great promise for meeting the health needs of highly marginalized Indigenous populations around the world, however, at this point more research is needed to understand how best to structure and deliver these programs for maximum effect.

Prevalence of psychological distress, depression and suicidal ideation in an indigenous population in Panamá

OBJECTIVE

The aim of this study was to investigate the prevalence of serious psychological distress (SPD), depression, and suicidal ideation in an adult Indigenous population in Panamá.

METHODS

Data were collected from 211 Kuna adults using a paper-based survey. Depression and suicidal ideation were measured using the Patient Health Questionnaire (PHQ-9), and SPD was measured using the Kessler-6. Univariate analyses were used to describe demographic variables, followed by chi² tests to compare differences in demographic variables for each of the mental health outcomes (depression, serious psychological distress, suicidal ideation). A regression model, adjusted for all demographic variables, was then run for each mental health outcome to understand independent correlates.

RESULTS

Within the sample surveyed, 6.2% (95% CI 3.4-10.4) reported serious psychological distress, 32.0% (95% CI 25.7-38.9) reported depression, and 22.9% (95% CI 17.4-29.1) reported suicidal ideation. Significant demographic differences existed with 14% of individuals between the age of 60-90 and 17% of individuals with no education reporting SPD. Women were nearly 5 times more likely to report depression than men (OR 4.90, 95% CI 1.27-19.00) and those with higher incomes were less likely to report depression (OR 0.32, 95% CI 0.13-0.78).

CONCLUSION

High levels of depression, SPD, and suicidal ideation were present in an Indigenous Kuna community in Panamá. Women and individuals with low income were more likely to report depression, and SPD was more common in older individuals and those with low levels of education. Suicidal ideation was high across all demographic factors, suggesting that a community-wide program to address suicide may be warranted.

Relationship between social determinants of health and systolic blood pressure in United States immigrants

This study examined the relationship between immigrant specific social determinants of health (SDoH) and blood pressure control. Data on 181 adult immigrants from the Midwestern United States was analyzed. SDoH variables were categorized based on antecedents, predisposing, enabling, and need factors. Systolic blood pressure (SBP) was the primary outcome. Pearson's correlations for the association between SBP and SDoH variables were assessed. Then three different regression approaches were used to assess the relationship of SDoH variables with SBP: sequential model, stepwise regression with backward selection, and all possible subsets regression. About 66% were female and mean age was 45.4 years. Age (r ​= ​0.34, p ​< ​0.001), disability (r ​= ​0.20, p ​= ​0.0001), comorbidities (r ​= ​0.30, p ​< ​0.001), and chronic pain (r ​= ​0.12, p ​= ​0.02) were positively correlated with SBP, and number of hours worked per week (r ​= ​-0.11, p ​= ​0.028) was negatively correlated with SBP. The final sequential model found life-course socioeconomic status (SES) (β ​= ​1.40, p ​= ​0.039), age (β ​= ​0.39, p ​< ​0.001), and male sex (β ​= ​13.62, p ​< ​0.001) to be positively associated with SBP. Stepwise regression found that life-course SES (β ​= ​1.70, p ​= ​0.026), age (β ​= ​0.36, p ​< ​0.001), male sex (β ​= ​13.38, p ​< ​0.001), and homelessness as a child (β ​= ​13.14, p ​= ​0.034) were positively associated SBP. All possible subsets regression found that age (β ​= ​0.44, p ​< ​0.001), male sex (β ​= ​14.50, p ​< ​0.001), and homelessness as a child (β ​= ​14.08, p ​= ​0.027) were positively associated with SBP. This is the first study to use a theory-based model that incorporates social determinants of health and immigrant specific factors to examine the relationship between SDoH and blood pressure control and identifies potential targets for interventions to control BP in immigrants.

Examination of dietary habits among the indigenous Kuna Indians of Panama

Background

Evidence for dietary habits among the Kuna Indians of Panama outside of cacao consumption is limited. Global trends suggest an uptake in processed foods conferring risk for chronic disease. This paper aims to provide information on dietary habits and investigate sociodemographic correlates of diet for the indigenous population living off the coast of Panama.

Methods

This sample included 211 Kuna Indians ages 18 years or older living within the island communities of Ustupu and Ogobsucum. Cross-sectional data was collected using a paper-based survey to assess dietary patterns. Categories of food included: fruits, vegetables, cacao, fish, sodas, fried, junk, and fast foods. Univariate analyses were used to describe demographic variables, followed by chi-squared tests to understand individual correlates of food types.

Results

About 85% reported eating fast food at least weekly, 47% reported eating fried food daily, and 11% reported eating junk food daily. Forty-three percent of the sample population reported eating fish daily. Those with poor incomes reported more fish consumption than any other income group (51%, p = 0.02). After adjusting for all covariates, those in higher income categories were less likely to eat fruits, cacao, and fish daily, but were also less likely to eat fast food weekly and junk food daily. Elderly populations (age 60–90 OR = 12.17, 95%CI 2.00, 73.84), women (OR = 3.43, 95%CI 1.23, 9.56), and those with primary education (OR = 4.83, 95%CI 1.01, 23.0) were also more likely to eat fast food weekly.

Conclusion

This is the first dietary survey study of the Kuna that focuses on food groups outside of cacao. Results suggest the community could benefit from efforts to increase cultivation of fruits and vegetables and reduce the percentage of energy consumption contributed by fast food, fried food, and junk food.

Prevalence and correlates of diagnosed and undiagnosed hypertension in the indigenous Kuna population of Panamá

BACKGROUND

To determine the prevalence of hypertension and investigate sociodemographic correlates in an indigenous Kuna community living on the San Blas islands of Panama.

METHODS

Data was collected from adults using a paper-based survey using a cross sectional study design. Blood pressure was measured, and hypertension defined at two cut-points: 130/80 mmHg and 140/90 mmHg. Individuals with undiagnosed hypertension had a blood pressure measurement that indicated hypertension, however, the individual had not been told by a doctor they had hypertension. Whereas individuals with diagnosed hypertension had been told by a healthcare provider that they had hypertension. Univariate tests compared diagnosed and undiagnosed hypertension by sociodemographic categories and logistic regression models tested individual correlates adjusting for all sociodemographic factors.

RESULTS

Two hundred and eleven adult indigenous Kuna participated in the study. Overall prevalence of hypertension was 6.2% (95%CI:3.32-10.30) as defined by 140/90 mmHg, and 16.6% (95%CI:11.83-22.31) as defined by 130/80 mmHg. Hypertension was significantly higher in men (31.6, 95% CI:19.90-45.24, compared to 11.0, 95% CI:6.56-17.09). Individuals with low income were 3 times more likely to be hypertensive (OR = 3.13, 95% CI:1.02-9.60) and 3.5 times more likely to have undiagnosed hypertension (OR = 3.42, 95% CI:1.01-11.52); while those with moderate income were 6 times more likely to be hypertensive (OR = 7.37, 95% CI:1.76-30.90) compared to those who were poor.

CONCLUSION

The prevalence of diagnosed and undiagnosed hypertension is higher in men and those with higher income. Investigating these factors remains vitally important in helping improve the health of the Kuna through targeted interventions to address chronic disease.

Racial and Ethnic Differences in Out-of-Pocket Expenses among Adults with Diabetes

BACKGROUND

Racial and ethnic minority groups have a higher prevalence of diabetes, increased risk for adverse complications, and worse health outcomes compared to Non-Hispanic Whites. Evidence suggests they also have higher healthcare expenses associated with diabetes care. Therefore, the objective of this study was to assess racial and ethnic differences in out-of-pocket (OOP) costs among a nationally representative sample of adults with diabetes.

METHODS

Cross-sectional study of 17,702 adults (aged ≥18 years) with diabetes from years 2002-2011 in the Medical Expenditure Panel Survey Household Component. The outcome was OOP expenditures, and the primary predictor was race/ethnicity. Descriptive statistics summarized the sample population. Unadjusted mean values were computed to compare OOP expenses over time. A two-part model was used to estimate adjusted incremental OOP expenses.

RESULTS

For the overall sample, OOP expenditures decreased significantly over time. In addition, compared to NHWs, racial and ethnic minority groups had significantly lower OOP costs per year when adjusted for sociodemographic characteristics, comorbid conditions, and time. NHBs paid $481 less than NHWs; Hispanics paid $591 less than NHWs; and individuals in the 'Other' racial/ethnic category paid nearly $645 less compared to NHWs (p < 0.001).

CONCLUSIONS

Racial/ethnic minority patients with diabetes had significantly less OOP expenses compared to NHWs, possibly due to differences in healthcare utilization. OOP expenses decreased significantly over time for all racial and ethnic groups. Additional research is needed to understand the factors associated with differences in OOP expenditures among racial groups.

Source of Education, Source of Care, Access to Glucometers, and Independent Correlates of Diabetes Knowledge in Ethiopian Adults with Diabetes

BACKGROUND

Knowledge, self-care and access to diabetes-related resources is critical to diabetes management. However, there is paucity of data on source of education, source of care, and access to diabetes-related resources in the developing world, including Ethiopia.

OBJECTIVE

To examine source of education, source of care, access to diabetes-related resources, and correlates of diabetes knowledge in a random sample of adults with diabetes in Ethiopia.

METHODS

A sample of 337 subjects was selected using systematic random sampling. Validated questionnaires were used to obtain data on source of education, source of care, access to diabetes-related resources, and diabetes knowledge. Multiple logistic and linear models were used to assess independent correlates of owning a glucometer and good diabetes knowledge.

RESULTS

Response rate was 91.1%. Correlates of access to glucometer were being ≥55 years of age (OR = 2.6 95% CI 1.0 to 6.73), having high school (OR = 3.5; 95% CI: 1.17 to 10.41) and college education (OR = 5.2; 95% CI: 1.67 to 16.27), higher income (OR = 3.3; 95% CI: 1.19 to 9.19), and receiving DM care in private hospital/clinics (OR = 9.4; 95% CI: 2.24 to 39.31). Independent correlates of poor diabetes knowledge were being age 40-54, being single, lack of education, lower monthly income (0-499 birr or $0 - $18.11), getting DM care from public hospitals, treatment with oral medications, and not owning a glucometer.

CONCLUSIONS

This study provides new insights on source of education, source of care, access to diabetes-related resources (e.g. glucometers, test strips), and correlates of diabetes knowledge in developing countries like Ethiopia that are experiencing an increasing prevalence of diabetes.

Differential Relationships Between Diabetes Knowledge Scales and Diabetes Outcomes

Background Diabetes affects more than 29 million people in the US and requires daily self-management in addition to knowledge of the disease. Three knowledge assessments used are the Michigan Brief Diabetes Knowledge Test (DKT), Starr County Diabetes Knowledge Questionnaire (DKQ), and Kaiser DISTANCE Survey (DISTANCE). Purpose The purpose of the study was to test the discriminate validity of 3 diabetes knowledge scales and determine which is best associated with diabetes self-care and glycemic control. Methods Three hundred sixty-one adults with type 2 diabetes were recruited from primary care clinics. Four analyses were conducted to investigate the validity and relationships of the scale: alpha statistic to test internal validity, factor analysis to determine how much of the variance was explained, Pearson's correlation between the 3 scales, and Pearson's correlation between each scale, self-care, and outcomes. Results The DKQ had an alpha of 0.75, the DKT had an alpha of 0.49, and DISTANCE had an alpha of 0.36. The DKQ was significantly correlated with glycemic control. The DKT scale was significantly associated with general diet, the DISTANCE survey was significantly associated with exercise, and both DKT and DISTANCE were significantly associated with foot care. Conclusion Correlations among the 3 scales were modest, suggesting the scales are not measuring the same underlying construct. These findings indicate that researchers should carefully select scales appropriate for study goals or to appropriately capture the information being sought to inform practice.
