Glucometer Use and Glycemic Control Among Hispanic Patients With Diabetes in Southern Florida

BACKGROUND Self-monitoring of blood glucose (SMBG) has been deemed a critical component of diabetes care in the United States. To be effective, patients must have some diabetes knowledge, glucometer proficiency, and an ability to take appropriate actions when certain readings are obtained. However, most patients take no action in response to out-of-range glucometer readings, and in many populations, SMBG practices are not associated with improved glycemic control. Thus, SMBG utilization is being reconsidered in other countries. Nonetheless, SMBG behaviors are increasingly recommended in the United States, where the Hispanic population represents the fastest-growing minority group and is disproportionately affected by suboptimal diabetes outcomes. Because a growing number of interventions aim to reduce diabetes disparities by improving glycemic control among minorities, it is essential to determine whether efforts should focus on SMBG practices. We present data on SMBG behaviors and glycemic control among participants from the Miami Healthy Heart Initiative (MHHI), a National Institutes of Health/National Heart, Lung, and Blood Institute-sponsored trial assessing a community health worker (CHW) intervention among Hispanic patients with poorly controlled diabetes. OBJECTIVE This study examined the effects of a CHW intervention on SMBG practices, glycosylated hemoglobin (HbA1c), and knowledge of appropriate responses to glucometer readings among Hispanic patients with diabetes. METHODS This study was an ancillary investigation within MHHI, a randomized, controlled trial in 300 Hispanic patients. Participants were intervention-group members who received 12 months of CHW support. Assessments were administered at baseline and poststudy to determine potential barriers to optimal health. Items from validated instruments were used to determine knowledge of appropriate responses to different glucose readings. These data were linked to HbA1c values. Means and frequencies were used to describe population characteristics and glucometer proficiency. Paired-sample t tests examined potential differences in HbA1c outcomes and SMBG practices. Qualitative data were collected from the CHWs who worked with study participants. RESULTS Our population was diverse, representing several countries. Mean HbA1c improved significantly, from 10% to 8.8% (P ≤ 0.001). SMBG practices did not change. At baseline, 96% of patients reported owning a glucometer and 94% reported knowing how to use it. However, quantitative assessments and qualitative data suggested that participants had suboptimal knowledge regarding actions that could cause an out-of-range reading or how to respond to certain readings. CONCLUSIONS SMBG behaviors were not associated with glycemic control in our sample. We conclude that a CHW intervention may improve glycemic control without improving SMBG practices. Future interventions may reconsider whether efforts should be directed toward improving SMBG behaviors.

Effect of a Community Health Worker Intervention Among Latinos With Poorly Controlled Type 2 Diabetes: The Miami Healthy Heart Initiative Randomized Clinical Trial.

Importance Community health worker (CHW) intervention is a promising approach to address type 2 diabetes among Latinos. However, evidence from randomized clinical studies is limited. Objective To compare a CHW intervention with enhanced usual care. Design, Setting, and Participants This 52-week, single-blind, randomized clinical trial included 300 Latino adults aged 18 to 65 years who were treated in 2 public hospital outpatient clinics in Miami-Dade County, Florida, from July 1, 2010, through October 31, 2013. Eligible participants had a hemoglobin A1c (HbA1c) level of 8.0 or greater. Follow-up was completed January 31, 2015, and data were analyzed from March 10, 2015, to June 6, 2016. Interventions A 1-year CHW intervention consisted of home visits, telephone calls, and group-level activities. Main Outcomes and Measures Primary outcomes included systolic blood pressure (SBP), low-density lipoprotein cholesterol (LDLC) levels, and HbA1c levels. Secondary outcomes included body mass index, medication regimen intensification, and self-reported measures of diet, physical activity, and medication regimen adherence. Results Of the 300 participants randomized (135 men [45%] and 165 women [55%]; mean [SD] age, 55.2 [7.0] years), we obtained follow-up data on 215 (71.7%). Participants in the CHW group received a median of 4 home visits and 20 telephone calls. After adjusting for baseline values and covariates, participants in the CHW group had an HbA1c level that was 0.51% lower (95% CI, −0.94% to −0.08%) than that of participants in the enhanced usual care group. The reduction in SBP of 4.62 mm Hg (95% CI, −9.01 to −0.24 mm Hg) did not meet the preplanned target of 8 mm Hg and was not statistically significant in unadjusted models. No significant differences in LDLC levels (mean difference, −8.2 mg/dL; 95% CI, −18.8 to 2.3 mg/dL) or any of the preplanned secondary outcomes were observed. Post hoc analyses suggest that the intervention may be more beneficial among those with worse control of their type 2 diabetes at baseline. Conclusions and Relevance Among Latinos with poorly controlled type 2 diabetes, a 12-month CHW intervention lowered HbA1c levels by 0.51%. The intervention did not lead to improvements in LDLC levels, and the findings with respect to SBP were variable and half of what was targeted. Future studies should examine whether CHW interventions affect other measures, such as access to health care or social determinants of health.

A Community Needs Assessment of the Physical Activity and Food Environment in a Predominantly Hispanic U.S. City

Introduction: Hispanics suffer disproportionately compared with non-Hispanic Whites from health conditions that are affected by physical inactivity and poor dietary habits. Method: A needs assessment was conducted in Hialeah, Florida, the largest enclave of Cubans in the United States, to assess the perspectives of community stakeholders and members regarding the roles of physical activity and nutrition environments. Interviews were performed with community stakeholders (n = 21), and responses were grouped into major themes. Surveys were conducted with community members (n = 85). Descriptive analyses were used to categorize responses and potential differences across responses were explored. Results: Both community members and stakeholders reported that the local park system was a major asset to healthy living in Hialeah and agreed that traffic issues and a lack of walkability were major barriers to being physically active; however, there was variability in the response to the quality of the food environment. Conclusion: The perspectives of the community members and stakeholders will be valuable in highlighting pathways to enhancing the health and wellness of the residents of Hialeah.

Tales from the Miami Healthy Heart Initiative: The Experiences of Two Community Health Workers

Community health workers (CHWs) have been bridging the gap between under-served populations and health care systems for centuries; however, their experiences are rarely recounted. The Miami Healthy Heart Initiative is a randomized control trial designed to examine the effectiveness of CHWs on reducing the risk for cardiovascular disease among Hispanics with poorly controlled diabetes in South Florida. This manuscript, told from the perspective of CHWs, is a summary of cases that were successful and some that did not achieve optimal outcomes. These case summaries include anecdotal data and clinical variables that demonstrate each patient’s progress during the intervention.

A profile of Latinos with poorly controlled diabetes in South Florida

Introduction Latinos are the largest minority group in the United States and diabetes or pre-diabetes affects more than 70% of Latinos aged 45 years and older. Miami-Dade County is home to one of the highest populations of diverse Latinos. In this descriptive manuscript, we present baseline characteristics of participants enrolled in the Miami Healthy Heart Initiative (MHHI). This was a study conducted to determine the effects of a community health worker (CHW) intervention among Latinos with poorly controlled diabetes in South Florida. Methods We recruited 300 diverse Latino adults with suboptimal diabetes outcomes (HbA1c≥8) into MHHI. This randomized control trial examined the impact of a 1-year CHW-led intervention on glycemic control, blood pressure, and cholesterol levels. At baseline, physiologic measures, including HbA1c, LDL, blood pressure, and BMI, were assessed. Data on socio-demographic characteristics and additional determinants of health such as depression status, provider communication, diet, exercise, cigarette smoking, readiness to change diabetes management behaviors (stages of change), and confidence in ability to improve diabetes self-care (self-efficacy) were collected. Results Participants came from 20 different countries, with Cuban Americans representing 38% of the sample. Most had lived in the US for more than 10 years, had completed at least 12 years of school, and had high levels of health literacy, yet 48% had very low acculturation. Nearly 80% had poor self-efficacy, 80% met the criteria for depression, and 83% were not adherent to their medications. More than half the population was not at their target for blood pressure, 50% were above the recommended LDL goal, and most were obese. Conclusion In a diverse population of Latinos with poorly controlled diabetes in Miami, we found high rates of depression, obesity, medication non-adherence, poor self-efficacy, and provider communication. These may contribute to poor diabetes control, high blood pressure, and elevated cholesterol.

Familias Unidas for Health and Wellness: Adapting an Evidence-Based Substance Use and Sexual Risk Behavior Intervention for Obesity Prevention in Hispanic Adolescents

We describe the adaptation of Familias Unidas, an evidence-based substance use and sexual risk behavior intervention, for obesity prevention in Hispanic adolescents. Intervention developers and experts in pediatric obesity, exercise physiology, dietetics, and the local parks system provided input for changes. Hispanic families also provided input through a series of 21 focus groups conducted before, during, and after an initial pilot test of the adapted intervention. After transcribing audiotaped sessions, we used a general inductive approach and Dedoose qualitative software to derive themes. Results indicated the need for improved health-related family functioning, enhanced nutrition education and skill building, increased family engagement in physical activity, and stronger links between family and environmental supports. Parents who participated in the pilot test expressed high enthusiasm for hands-on nutrition training and reported improvements in family functioning. Adolescents liked outdoor physical activities but wanted parents to be more engaged in joint physical activity sessions. The adapted intervention maintains fidelity to Familias Unidas’ core theoretical elements and overall structure, but also includes content focused on physical activity and nutrition, adolescent participation in physical activity sessions led by park coaches, and joint parent-adolescent participation in physical activity and nutrition skill-building activities.

Effects of parent-adolescent reported family functioning discrepancy on physical activity and diet among Hispanic youth.

Research has shown that family functioning has been positively associated with physical activity and dietary intake, both of which are obesity-related risk factors. The most widely practiced methodological approach to assessing this construct in empirical studies relies on either parent or adolescent report. Yet, discrepancy in parent and adolescent report of family functioning may provide a fuller understanding of the effects of this construct on obesity-related health outcomes. This is especially important among Hispanics, a population that suffers from disproportionately high rates of obesity and its health-related consequences. The purpose of this study was to examine whether, and to what extent, parent-adolescent discrepancies in family functioning are associated with physical activity, and fruit and vegetable and added sugar intake. We estimated discrepancy scores between parents and adolescents (n = 280 dyads) in family functioning. Then, using structural equation modeling, we tested the effect of family functioning discrepancy on adolescent reports of physical activity, fruits and vegetables intake, and added sugar intake. After controlling for adolescent’s gender and BMI, family functioning discrepancy was significantly associated with reduced physical activity (&bgr; = −.14*, 95% CI ([−.26, −.05]) and fruits and vegetables intake (&bgr; = −.22*, 95% CI [−.38, −.09]) such that the larger the discrepancy between parent and youth reported family functioning, the fewer days of adolescent physical activity and the poorer the fruits and vegetables intake. Our findings provide insight for the role of the family in Hispanic adolescent health outcomes and rationale for capturing rich data to better understand that role.

Medication administration by caregiving youth: An inside look at how adolescents manage medications for family members

INTRODUCTION Children take on the role of family caregiver throughout the world. No prior published research exists surrounding the particular circumstances of the task of medication administration and management by these youth, which was explored in this study. METHODS A series of focus groups were conducted using semi-structured interviews of 28 previously identified caregiving youth ages 12-19 years old who live in the United States. Data analysis followed guidelines of conventional content analysis. RESULTS The following categories emerged about youth caregivers handling medications: 1) tasks involve organizational and administrative responsibilities; 2) youth have varying degrees of knowledge pertaining to these medications; 3) most share responsibility with other family members; 4) they lack formal education about their responsibilities; 5) multiple challenges exist relating to this task; 6) managing medications is associated with emotional responses; and 7) possible safety issues exist. CONCLUSIONS These responsibilities represent a unique hardship and merit support and research from the medical, healthcare, legislative, and public health communities, among others.

The Role of Physical Activity and Sedentary Behavior in Substance Use and Risky Sex Behaviors in Hispanic Adolescents

The purpose of our study was to investigate the potential relationships in Hispanic adolescents (n = 575) between substance use and/or risky sexual behaviors and (a) physical activity (PA) and (b) sedentary time and (c) the moderating effect of gender. PA levels and sedentary behaviors were assessed using the PA Questionnaire for Adolescents, while risky behaviors were assessed using items similar to those used in the national epidemiological study, Monitoring the Future. We found significant, positive associations between PA and smoking, drug use, and risky sex measures. Similar positive associations existed between sedentary time and risky behaviors. However, after stratifying by gender, most of the relationships remained significant only for males. Our study is among the first to examine these relationships in Hispanic adolescents. Given the emphasis on increasing PA and decreasing sedentary behavior in adolescents, more efforts should be dedicated to understanding the effect of these lifestyle habits on risky behaviors.

Beyond Sensitivity. LGBT Healthcare Training in U.S. Medical Schools: A Review of the Literature

ABSTRACT Purpose: Training future physicians to address the health needs of the lesbian, gay, bisexual, and transgender (LGBT) population can potentially decrease health disparities faced by such individuals. In this literature review, we examine the characteristics and impact of current LGBT healthcare training at U.S. medical schools. Methods: We performed a comprehensive literature search to identify studies on LGBT healthcare training in U.S. medical schools. Studies published between January 2000 and September 2016 that described the program and reported on at least one quantitative evaluative measure were included in our review. Results: We found 13 studies meeting our inclusion criteria. The programs had high levels of variability in curricular content, educational strategies used, duration, and evaluation methods. Many programs utilized an interactive experience involving a standardized patient. The majority of participants in such programs felt this approach was an effective learning strategy. All programs reported that participants felt the training improved their ability to provide more effective healthcare to LGBT patients. Conclusion: Despite wide variability in their training approaches, the 13 programs we reviewed provided data suggesting a positive impact of LGBT healthcare training.
