Hispanic Patient Perspectives of the Physician's Role in Obesity Management

Perceived intrinsic, social, and environmental barriers for weight management in older Hispanic/Latino adults with obesity

Background

The burden of obesity and chronic disease is increasing in the older US Hispanic/Latino adult population. There is limited evidence on successful weight management strategies as perceived by this population. Assessing barriers and opportunities for weight management using mixed methods is a robust approach to collect in-depth information that can be applied to the development of well-tailored weight management interventions for this population.

Objective

The objective of this study was to assess perceived individual, interpersonal, and environmental factors that influence weight management in older Hispanic/Latino adults.

Methods

This community-based cross-sectional study included 23 Hispanic/Latino older (>50y) adults with obesity (BMI >30 kg/m²). Perceived barriers and opportunities for weight management were assessed through validated questionnaires and focus groups. Prospectively registered on ClinicalTrials.gov (NCT03978416) on 7 June 2019.

Results

In this demographically heterogeneous population, language acculturation was generally low, and the frequency of poor dietary behaviors was high. Participants linked financial strain to lower diet quality, as well as anxiety to uncontrolled eating and food cravings. Social support and trust in healthcare professionals were perceived as priorities for healthy eating. Structural and environmental barriers such as affordability and availability of culturally preferred foods were also identified as influences on food choices and eating behavior.

Conclusions

This study revealed opportunities for culturally tailored weight management interventions in older Hispanic/Latino adults with obesity.

Delivering the Same Intervention to Hispanic/Latinos With Pre-diabetes and Diabetes. Early Evidence of Success in a Longitudinal Mixed Method Study

BACKGROUND

Despite nationwide efforts to address the diabetes epidemic and reduce prevalence disparities, higher rates persist among the poor, especially those with limited literacy. Currently, individuals with abnormal glycemia who have pre-diabetes and diabetes qualify for different programs. However, evidence suggests that, for low-income Hispanic/Latinos, offering a single intervention to all those with abnormal glycemia may provide a more culturally acceptable and effective approach. Our objective was to explore the feasibility of such an intervention led by community health workers (CHWs) among low-income Hispanic/Latinos with diabetes and at risk for diabetes.

METHODS

Using a quasi-experimental mixed method design, we assessed weight, glycosylated hemoglobin, diabetes knowledge, and behavior changes of Hispanic/Latinos participants with pre-diabetes and diabetes living in Southern California. Biometric measurements, blood tests, and surveys were collected at baseline and 3 months post-intervention. Interviews and focus group discussions provided qualitative data.

RESULTS

Although the program was less costly, results exceeded those reported for low-income H/L attending the National Diabetes Prevention Program and did not differ between pre-diabetes and diabetes groups. Instead, including individuals at different stages of the dysglycemic spectrum seemed to have enhanced the intervention. Physician referral and attendance of family/friends were associated with better outcomes.

CONCLUSION

Our findings indicate that a joint prevention/self-management intervention led by CHWs for low-income Hispanic/Latinos with diabetes and with pre-diabetes is feasible and cost-effective, providing results that could help reduce the success gap. Incorporating suggestions and replicating this study on a larger scale could help determine whether or not results are reproducible.

A Qualitative Study on the Perspectives of Latinas Enrolled in a Diabetes Prevention Program: Is the Cost of Prevention Too High?

Introduction: Latinas are among the groups most affected by diabetes health disparities, yet they often benefit less from diabetes interventions even when these are culturally adapted. The purpose of this qualitative study was to explore readiness of Latinas enrolled in a diabetes prevention program to adopt recommended preventive behaviors, and to identify factors associated with the adoption and maintenance of these recommended lifestyle changes. Insights gained will be used to inform future efforts at reducing diabetes disparities and the burden of chronic diseases among Latinas. Methods: Nine focus group discussions (FGDs) and 3 key informant interviews (KIIs) were conducted after the completion of a culturally adapted diabetes prevention program led by Latino community health workers. A grounded theory approach by Charmaz informed by the transtheoretical model guided the questions. Discussions and interviews were audio-taped with participants’ permission, transcribed, coded, and themed. Results: Forty low-income Latinas contributed to FGDs and KIIs. Baseline readiness to engage in new behaviors varied. Negative personal and family health events and physician referral impacted most readiness to enroll and to adopt preventive behaviors. Built environment, financial constraints, and threat of social alienation constituted major barriers to behavior adoption and maintenance, while physician involvement, awareness of diabetes complications, and social support partially mitigated these impediments. Conclusions: Our results suggest that timing of enrollment, physician-patient dynamics, and the emotional personal/family cost of behavior modification should all be considered when planning diabetes prevention programs for low-income Latinas. Besides appropriately timing referrals to accessible culturally informed prevention programs, health educators and health care providers should be aware of the potentially negative impact of behavior modification on family dynamics and be prepared to address resulting repercussions. Future research on Latinas should also include and report data on physician involvement, family context, and social determinants of health for more consistent program comparisons.

Letter to the Editor Re: Kipperman, B.S. and German, A.J. Animals 2018, 8, 143

A recent opinion paper by Kipperman and German (2018) discussed the increasing prevalence of pet obesity, the risk factors contributing to this increase, and the role of veterinarians in helping manage pet obesity. They described the problem as a One Health problem as it has been previously characterized. Kipperman and German also reported a sample of medical records from their referring veterinarians wherein a surprisingly small number of veterinarians recorded information about pets' body weight or discussions with owners about pet obesity. From their sample, they concluded that general practice veterinarians are not meeting their professional and ethical obligations to recognize and address pet obesity. This letter discusses reasons why veterinarians may not be adequately addressing the pet obesity problem. A similar situation exists in human medicine. Numerous studies in the human field have revealed some of the reasons many physicians do not address obesity with their patients. As it is likely that veterinarians have similar reasons for avoiding the obesity issue, obstacles identified by physicians in encountering overweight obesity are reviewed in this letter.

Physical Activity in Older Mexican Americans Living in Two Cities on the U.S.-Mexico Border

BACKGROUND

There is limited information on physical activity in marginalized older populations like that on the U.S.-Mexico border. This study aims to understand physical activity engagement among older Hispanics residing in two U.S.-Mexico Border counties.

METHODS

The International Physical Activity Questionnaire (IPAQ) was used to measure physical activity in El Paso and Cameron County, Texas. Physical activity levels were reported for vigorous, moderate, and walking met/mins. Adjusted and unadjusted modeling was conducted to determine county differences and sociodemographic covariates.

RESULTS

There were 784 participants and 92.9% were less than 65 years of age. El Paso participants reported a significantly greater natural log met/mins of vigorous (β = 1.34, p = 0.000) and walking (β = 0.331, p = 0.006). Significant sociodemographic covariates in El Paso for vigorous met/mins were gender (females β = -1.20, p = 0.003), having a regular doctor (β = -0.779, p = 0.029), and acculturation (β = 0.513, p = 0.019). Significant associations in Cameron County were having a regular doctor (β = -1.03, p = 0.000) and fair/poor health status (β = -0.475, p = 0.001).

CONCLUSION

Level of physical activity may differ in older Hispanics by urban context on the U.S.-Mexico border. Future physical activity programs to promote physical activity should take context into consideration.

Body mass index and mobility limitations: An analysis of middle-aged and older Black, Hispanic, and White women in the U.S

INTRODUCTION

While the Body Mass Index (BMI) did not change significantly for men from 2005 to 2014 in the United States, women exhibited an upward linear trend. Hispanic and Black women, in particular, showed a dramatic increase. Therefore, the objective of this study was to examine the association between BMI and mobility limitations for non-institutionalised middle-aged and older Black, Hispanic, and White women.

METHODS

The International Classification of Functioning, Disability, and Health model was applied to a sample of 2865 Black, 1846 Hispanic, and 9721 White women categorised as middle-aged and older (i.e., at least 50 years of age) from the 2010 and 2014 Rand Health and Retirement Study. A random effects ordered logit was employed.

RESULTS

After accounting for personal/activity characteristics, the analyses revealed Black women with greater BMI were associated with a higher likelihood for mobility limitations with an odds ratio of 1.11 [1.06-1.16, 95% CI]. A significant association was also found for Hispanic women with an odds ratio of 1.16 [1.11-1.23, 95% CI] and White women with an odds ratio of 1.16 [1.13-1.19, 95% CI]. Even after accounting for the possibility of endogeneity, BMI remained robust.

CONCLUSION

Higher-levels of BMI were associated with an increased probability for mobility limitations for Black, Hispanic, and White middle-aged and older women. Those with a vigorous exercise regimen were less likely to be in this category across all ranges of BMI. These results are useful for prioritising minority health policy, particularly given the limited amount of existing research in this specific area.
