Regional, geographic, and racial/ethnic variation in glycemic control in a national sample of veterans with diabetes.

ABSTRACT:

Objective

We performed a retrospective analysis of a national cohort of veterans with diabetes to better understand regional, geographic, and racial/ethnic variation in diabetes control as measured by HbA(1c).

Research design and methods

A retrospective cohort study was conducted in a national cohort of 690,968 veterans with diabetes receiving prescriptions for insulin or oral hypoglycemic agents in 2002 that were followed over a 5-year period. The main outcome measures were HbA(1c) levels (as continuous and dichotomized at ?8.0%).

Results

Relative to non-Hispanic whites (NHWs), HbA(1c) levels remained 0.25% higher in non-Hispanic blacks (NHBs), 0.31% higher in Hispanics, and 0.14% higher in individuals with other/unknown/missing racial/ethnic group after controlling for demographics, type of medication used, medication adherence, and comorbidities. Small but statistically significant geographic differences were also noted with HbA(1c) being lowest in the South and highest in the Mid-Atlantic. Rural/urban location of residence was not associated with HbA(1c) levels. For the dichotomous outcome poor control, results were similar with race/ethnic group being strongly associated with poor control (i.e., odds ratios of 1.33 [95% CI 1.31-1.35] and 1.57 [1.54-1.61] for NHBs and Hispanics vs. NHWs, respectively), geographic region being weakly associated with poor control, and rural/urban residence being negligibly associated with poor control.

Conclusions

In a national longitudinal cohort of veterans with diabetes, we found racial/ethnic disparities in HbA(1c) levels and HbA(1c) control; however, these disparities were largely, but not completely, explained by adjustment for demographic characteristics, medication adherence, type of medication used to treat diabetes, and comorbidities.

Project description:Purpose: Equal-access health care systems such as the Veterans Health Administration (VHA) reduce financial and nonfinancial barriers to care. It is unknown if such systems mitigate racial/ethnic mortality disparities, such as those well documented in the broader U.S. population. We examined racial/ethnic mortality disparities among VHA health care users, and compared racial/ethnic disparities in VHA and U.S. general populations. Methods: Linking VHA records for an October 2008 to September 2009 national VHA user cohort, and National Death Index records, we assessed all-cause, cancer, and cardiovascular-related mortality through December 2011. We calculated age-, sex-, and comorbidity-adjusted mortality hazard ratios. We computed sex-stratified, age-standardized mortality risk ratios for VHA and U.S. populations, then compared racial/ethnic disparities between the populations. Results: Among VHA users, American Indian/Alaskan Natives (AI/ANs) had higher adjusted all-cause mortality, whereas non-Hispanic Blacks had higher cause-specific mortality versus non-Hispanic Whites. Asians, Hispanics, and Native Hawaiian/Other Pacific Islanders had similar, or lower all-cause and cause-specific mortality versus non-Hispanic Whites. Mortality disparities were evident in non-Hispanic-Black men compared with non-Hispanic White men in both VHA and U.S. populations for all-cause, cardiovascular, and cancer (cause-specific) mortality, but disparities were smaller in VHA. VHA non-Hispanic Black women did not experience the all-cause and cause-specific mortality disparity present for U.S. non-Hispanic Black women. Disparities in all-cause and cancer mortality existed in VHA but not in U.S. population AI/AN men. Conclusion: Patterns in racial/ethnic disparities differed between VHA and U.S. populations, with fewer disparities within VHAs equal-access system. Equal-access health care may partially address racial/ethnic mortality disparities, but other nonhealth care factors should also be explored.

Project description:ObjectiveTo examine whether there are: 1) regional differences in three perinatal interventions that reflect active treatment among periviable gestations and 2) racial-ethnic differences in the receipt of these perinatal interventions after accounting for hospital region.MethodsWe conducted a retrospective study on neonates born at 776 U.S. centers that participated in the Vermont Oxford Network (2006-2017) with a gestational age of 22-25 weeks. The primary outcome was postnatal life support. Secondary outcomes included maternal administration of antenatal corticosteroids and cesarean delivery. We examined rates and 99% CI of the three outcomes by region. We also calculated the adjusted relative risks (aRRs) and 99% CIs for the three outcomes by race and ethnicity within each region using modified Poisson regression models with robust variance estimation.ResultsMajor regional variation exists in the use of the three interventions at 22 and 23 weeks of gestation but not at 24 and 25 weeks. For example, at 22 weeks of gestation, rates of life support in the South (38.3%; 99% CI 36.3-40.2) and the Midwest (32.7%; 99% CI 30.4-35.0) were higher than in the Northeast (20.2%; 99% CI 17.6-22.8) and the West (22.2%; 99% CI 20.0-24.4). Particularly in the Northeast, black and Hispanic neonates born at 22 or 23 weeks of gestation had a higher provision of postnatal life support than white neonates (at 22 weeks: black: aRR 1.84 [99% CI 1.33-2.56], Hispanic: aRR 1.80 [1.23-2.64]; at 23 weeks: black: aRR 1.14 [99% CI 1.08-1.20], Hispanic: aRR 1.12 [1.05-1.19]). In the West, black and Hispanic neonates born at 23 weeks of gestation also had a higher provision of life support (black: aRR 1.11 [99% CI 1.03-1.19]; Hispanic: aRR 1.10 [1.04-1.16]).ConclusionMajor regional variation exists in perinatal interventions when managing 22- and 23-week neonates. In the Northeast and the West regions, minority neonates born at 22 and 23 weeks of gestation had higher provision of postnatal life support.

Project description:Significant racial/ethnic disparities in unintended pregnancy persist in the United States, with the highest rates observed among low-income black and Hispanic women. Differences in contraceptive preferences, beliefs, and self-efficacy may be instrumental in understanding contraceptive behaviors that underlie higher rates of unintended pregnancy among racial/ethnic minorities.Our objective was to understand how contraceptive preferences, beliefs, and self-efficacy vary by race and ethnicity among women veterans.We analyzed data from the Examining Contraceptive Use and Unmet Need Study, a national telephone survey of women veterans aged 18-44 years who had received primary care at the Veterans Administration in the prior 12 months. Participants rated the importance of various contraceptive characteristics and described their level of agreement with contraceptive beliefs using Likert scales. Contraceptive self-efficacy was assessed by asking participants to rate their certainty that they could use contraception consistently and as indicated over time using a Likert scale. Multivariable logistic regression was used to examine associations between race/ethnicity and contraceptive attitudes, controlling for age, marital status, education, income, religion, parity, deployment history, and history of medical and mental health conditions.Among the 2302 women veterans who completed a survey, 52% were non-Hispanic white, 29% were non-Hispanic black, and 12% were Hispanic. In adjusted analyses, compared with whites, blacks had lower odds of considering contraceptive effectiveness extremely important (adjusted odds ratio; 0.55, 95% confidence interval, 0.40-0.74) and higher odds of considering the categories of does not contain any hormones and prevents sexually transmitted infections extremely important (adjusted odds ratio, 1.94, 95% confidence interval, 1.56-2.41, and adjusted odds ratio; 1.99, 95% confidence interval, 1.57-2.51, respectively). Hispanics also had higher odds than whites of considering the category of does not contain any hormones and prevents sexually transmitted infections extremely important (adjusted odds ratio, 1.72, 95% confidence interval, 1.29-2.28, and adjusted odds ratio, 1.63; 95% confidence interval, 1.21-2.19, respectively). Compared with whites, blacks and Hispanics had higher odds of expressing fatalistic beliefs about pregnancy (adjusted odds ratio, 1.79, 95% confidence interval, 1.35-2.39, and adjusted odds ratio, 1.48, 95% confidence interval, 1.01-2.17, respectively); higher odds of viewing contraception as primarily a woman's responsibility (adjusted odds ratio, 1.92, 95% confidence interval, 1.45-2.55, and adjusted odds ratio, 1.77; 95% confidence interval, 1.23-2.54, respectively); and lower odds of being very sure that they could use a contraceptive method as indicated over the course of a year (adjusted odds ratio, 0.73, 95% confidence interval, 0.54-0.98, and adjusted odds ratio, 0.66, 95% confidence interval, 0.46-0.96, respectively).Women veterans' contraceptive preferences, beliefs, and self-efficacy varied by race/ethnicity, which may help explain observed racial/ethnic disparities in contraceptive use and unintended pregnancy. These differences underscore the need to elicit women's individual values and preferences when providing patient-centered contraceptive counseling.
