Efficacy of Behavioral Interventions on Biological Outcomes for Cardiovascular Disease Risk Reduction among Latinos: a Review of the Literature

Associations of Anxiety Symptoms With 6-Year Blood Pressure Changes and Incident Hypertension: Results From the Hispanic Community Health Study/Study of Latinos

BACKGROUND

Despite the high burden of anxiety and hypertension in Hispanic/Latino adults, little is known about their association in this population.

PURPOSE

To examine the associations of anxiety symptoms with 6-year changes in blood pressure (BP) and incident hypertension in Hispanic/Latino adults.

METHODS

We examined data from a probability sample of 10,881 Hispanic/Latino persons aged 18-74 who attended visits 1 (V1; 2008-2011) and 2 (V2; 2014-2017) of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a prospective cohort study. Anxiety symptoms were assessed at V1 using the 10-item Spielberger Trait Anxiety Scale (M = 17.1; Range = 10-40) and dichotomized using a cut-point of 20, the highest quartile in this cohort. BP was measured at both visits using a standardized protocol.

RESULTS

Adults with elevated anxiety symptoms had a 1.02 mm Hg greater increase in systolic (p = .02) and a 0.75 mm Hg greater increase in diastolic BP (p = .02) over 6.1 years than those with lower symptoms, after adjusting for sociodemographic and clinical covariates. These associations differed by sex. Elevated anxiety was associated with a greater increase in systolic and diastolic BP in men only. Among persons without hypertension at V1 (N = 7,412), those with elevated anxiety symptoms at V1 had a 22% higher incidence of hypertension (p = .02) 6.1 years later.

CONCLUSIONS

Our findings underscore the importance of screening for and treating elevated anxiety symptoms to help prevent hypertension. Further research on the role of sex and underlying mechanisms is warranted.

Feasibility and Outcomes of Meta Salud Diabetes Behavioral Health Intervention: A Pilot Study of a Community Health Worker-Administered Educational Intervention to Prevent Cardiovascular Disease and Its Complications among Hispanic Patients with Type-2 Diabetes

BACKGROUND

Hispanics in the United States experience a greater burden of type-2 diabetes (T2D), with a prevalence rate (17%) more than twice that of non-Hispanic whites (8%). Cardiovascular disease (CVD) is the leading cause of death among people with T2D. A culturally appropriate behavioral health intervention that addresses healthy lifestyle promotion is an impactful approach for health systems with scarce medical resources and a high prevalence of chronic conditions, including obesity and high blood pressure, which increase the likelihood of CVD mortality among type-2 diabetics.

PURPOSE

To assess the feasibility and outcomes of a behavioral intervention to decrease CVD and complications in a Hispanic diabetic population.

METHODS

Meta Salud Diabetes (MSD), a behavioral intervention effective in a Mexican population, consists of a 13-week intervention addressing CVD and T2D knowledge and risk reduction. It was implemented in a sample of Hispanic diabetic patients from two federally qualified health centers (FQHCs). Clinical and behavioral variables were measured at baseline, postintervention, and 1-year follow-up.

RESULTS

The feasibility of MSD was rated as successful by all FQHC staff and well-received by both staff and study participants, with positive remarks about the culturally relevant components of the intervention. The sample size was n = 30 (baseline), n = 23 (postintervention), and n = 19 (1-year follow-up). Of note, quantitative results showed trending decreases in Hba1c (7.06; 6.80; 6.30), blood pressure (132/83; 126/80; 123/78), and total cholesterol (160; 159; 154).

CONCLUSION

MSD is a feasible intervention and can address the need to improve health outcomes among Hispanic patients with T2D.

Delivering ADAPT+ to Latino Families Living in Rural Communities: Feasibility and Acceptability of Implementing a Health Promotion Program Including Mindfulness

BACKGROUND

Obesity is a major public health crisis in Latino youth. Mounting evidence implicates stress in the development and maintenance of obesity. This study examined the feasibility and acceptability of having community health workers, i.e., promotoras, deliver Adaptando Dieta y Acción Para Todos (ADAPT)+, a family-based health promotion program integrating mindfulness strategies for stress reduction to underserved Latino families in rural communities.

METHODS

In an ORBIT model Phase IIb longitudinal quasi-cluster feasibility study, promotoras delivered the 6-session ADAPT+ intervention and 1-session Enhanced Usual Care (EUC) in rural Florida. Feasibility was assessed via sample size and recruitment, randomization by community, data collection completion, and intervention fidelity. Acceptability was assessed via participant retention and program satisfaction. Effect sizes of differences in parent stress and mindful eating between conditions at baseline, end of treatment, and 3-month follow-up were calculated.

RESULTS

Feasibility and acceptability were demonstrated. The recruitment target was 99% met (n = 95 recruited). Randomization was limited to site level due to coronavirus disease 2019-related challenges. Data collection procedures were feasible (100% completion). Retention was 86% at post-assessment and 82.6% at 3-month follow-up. All sessions were completed (100% fidelity). Mean program satisfaction was 3.91/4.00. ADAPT+ parents reported lower stress (difference = -3.04, medium-to-large effect, d = .70) and more mindful eating (difference = 2.00, medium effect, d = .44) than EUC parents at 3-month follow-up.

CONCLUSION

Study implementation and intervention delivery to rural Latino families using promotoras were feasible and acceptable. Promising findings regarding parent stress and mindful eating support a larger (ORBIT Phase III) efficacy trial.

CLINICAL TRIAL REGISTRATION

This trial was registered with ClinicalTrials.gov under identifier NCT04800432.

Results from the Strong Families Start at Home/Familias Fuertes Comienzan en Casa: feasibility randomised control trial to improve the diet quality of low-income, predominantly Hispanic/Latinx children

OBJECTIVE

To describe the feasibility, acceptability and results of Strong Families Start at Home, a 6-month pilot trial of a home-based food parenting/nutrition intervention.

DESIGN

Pilot randomised controlled trial.

SETTING

Participants received six visits with a community health worker trained in motivational interviewing (three home visits, three phone calls); an in-home cooking or reading activity; personalised feedback on a recorded family meal or reading activity; text messages and tailored printed materials.

PARTICIPANTS

Parents and their 2-5-year-old child were randomised into intervention (responsive food parenting practices/nutrition) or control (reading readiness) groups.

RESULTS

Parents (n 63) were mostly mothers (90 %), Hispanic/Latinx (87 %), born outside the USA (62 %), with household incomes <$25 k (54 %). Despite delivery during COVID-19, 63 % of dyads were retained at 6 months. The intervention was delivered with high fidelity. All parents in the intervention group (n 24) expressed high levels of satisfaction with the intervention, which produced positive treatment effects for whole and total fruit component Healthy Eating Index-2015 scores (point estimate (PE) = 2·14, 95 % CI (0·17, 1·48); PE = 1·71, 95 % CI (0·16, 1·47), respectively) and negative treatment effects for sodium (PE = -2·09, 95 % CI (-1·35, -0·04)). Positive treatment effects also resulted for the following food parenting practices: regular timing of meals and snacks (PE = 1·08, 95 % CI (0·61, 2·00)), reducing distractions during mealtimes (PE = -0·79, 95 % CI (-1·52, -0·19)), using food as a reward (PE = -0·54, 95 % CI (-1·35, -0·04)) and providing a supportive meal environment (PE = 0·73, 95 % CI (0·18, 1·51)).

CONCLUSION

Given the continued disparities in diet quality among low-income and diverse families, continued efforts to improve child diet quality in fully powered intervention trials are needed.

The role of behavioral science in addressing cardiovascular health disparities: A narrative review of efforts, challenges, and future directions

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality in the United States. Despite improvements in the prevention and treatment of CVD over the past 20 years, racial/ethnic minority groups including non-Hispanic Blacks, Hispanic/Latinos, and some Asian subgroups (e.g., Asian Indians, Filipinos) experience higher rates of CVD risk factors and morbidity and mortality from CVD than non-Hispanic Whites. Therefore, addressing cardiovascular health disparities is an immediate priority. Behavioral science can play an important role in reducing disparities by capitalizing on expertise in human behavior change, social determinants of health, and implementation science. In this narrative review, we describe the efforts made within behavioral science to address CVD health disparities. We review current interventions to reduce CVD health disparities and provide practical recommendations that can be used as the field moves forward.

Effectiveness of a Promotores Network to Improve Health in an Emerging Latino Community

BACKGROUND

Latinos living in emerging communities (i.e., nontraditional destinations with a small but growing population) face obstacles to their mental and physical health. This study evaluated the effectiveness of a 6-month, promotor-led intervention on access to care, physical activity, dietary practices, and perceived social support among Latino adults living in an emerging community, compared with a nonrandomly assigned control group.

METHOD

Participants (n = 81 intervention; n = 86 control) were drawn from Allegheny county, Pennsylvania. Promotores used an intervention tool offering nondirective social support to assist participants in developing SMART goals to address their life concerns in eight domains (e.g., social, diet, and exercise/recreation); the control group received printed materials. Participants completed a survey in Spanish at baseline and follow-up to assess outcomes and had their height and weight measured. Adjusted linear mixed effects models compared change in outcomes over time.

RESULTS

There was a marginally significant improvement in dietary practices in the intervention group at follow-up, and no change in access to care. Both groups experienced an improvement in social support. There was a significant intervention-by-time interaction such that the intervention group increased physical activity by 259 minutes/week compared with the control group.

CONCLUSION

This study demonstrates the potential effectiveness of a promotores network in assisting individuals living in an emerging Latino community to address their life concerns and improve health behaviors. Future studies should include objective and more rigorous measures with a larger sample to replicate these results.

The Effects of Physical Activity on Arterial Stiffness during Pregnancy: An Observational Study

The objective of the present study was to investigate the relationship between moderate-to-vigorous physical activity (MVPA) and arterial stiffness in pregnancy. Thirty-nine women participated in this study resulting in 68 measurements in non-pregnant (NP; n=21), first (TM1; n=8), second (TM2; n=20), and third trimesters (TM3; n=19). Compliance, distensibility, elasticity, β-stiffness, and carotid to femoral (central) and carotid to finger (peripheral) pulse wave velocity (PWV) were assessed. MVPA was measured using accelerometry. Multilevel linear regressions adjusted for multiple tests per participant using random effects to generate β coefficients and 95% confidence intervals (CI) were performed. Distensibility, elasticity, β-stiffness, central- and peripheral-PWV did not differ between pregnant and non-pregnant assessments. Carotid artery compliance was higher in TM2 compared to NP. Central PWV (β Coef: -0.14, 95% CI: -0.27, -0.02) decreased from early to mid-pregnancy and increased in late pregnancy. Meeting the MVPA guidelines was significantly associated with central-PWV (Adj. β Coef: -0.34, 95% CI: -0.62, -0.06, p=0.016), peripheral-PWV (Adj. β Coef: -0.54, 95% CI: -0.91, -0.16, p=0.005), and distensibility (Adj. β Coef: -0.001, 95% CI: -0.002, -0.0001, p=0.018), in pregnancy. These results suggest that MVPA may be associated with improved (i.e. reduced) arterial stiffness in pregnancy. Novelty Bullets • Central PWV, distensibility, compliance, elasticity, and ß-stiffness, but not peripheral PWV, exhibited curvilinear relationships with gestational age • Central and peripheral PWV were lower in pregnant women who met the physical activity guidelines of 150 minutes of moderate-to-vigorous physical activity per week.

Unpacking the 'black box' of lay health worker processes in a US-based intervention

Prior studies have supported the effectiveness of the use of Lay Health Workers (LHWs) as an intervention model for managing chronic health conditions, yet few have documented the mechanisms that underlie the effectiveness of the interventions. This study provides a first look into how LHWs delivered a family-based intervention and the challenges encountered. We utilize observation data from LHW-led educational sessions delivered as part of a randomized controlled trial (RCT) designed to test a LHW outreach family-based intervention to promote smoking cessation among Vietnamese American smokers. The RCT included experimental (smoking cessation) and control (healthy living) arms. Vietnamese LHWs were trained to provide health information in Vietnamese to groups of family dyads (smoker and family member). Bilingual, bicultural research team members conducted unobtrusive observations in a subset of LHW educational sessions and described the setting, process and activities in structured fieldnotes. Two team members coded each fieldnote following a grounded theory approach. We utilized Atlas.ti qualitative software to organize coding and facilitate combined analysis. Findings offer a detailed look at the 'black box' of how LHWs work with their participants to deliver health messages. LHWs utilized multiple relational strategies, including preparing an environment that enables relationship building, using recognized teaching methods to engage learners and co-learners as well as using humor and employing culturally specific strategies such as hierarchical forms of address to create trust. Future research will assess the effectiveness of LHW techniques, thus enhancing the potential of LHW interventions to promote health among underserved populations.

Mujeres Fuertes y Corazones Saludables, a Culturally Tailored Physical Activity and Nutrition Program for Rural Latinas: Findings from a Pilot Study

In the United States, Latino adults, compared with non-Hispanic white adults, are less likely to meet physical activity and dietary recommendations, and have higher rates of obesity. There is an urgent need for culturally adapted health promotion programs that meet the needs of the growing Latino population in the United States. We systematically adapted StrongWomen-Healthy Hearts, an evidence-based physical activity and nutrition program, for rural Latinas. This paper reports results from a pilot study of the adapted program. We used mixed methods to assess the feasibility and efficacy of the adapted program, Mujeres Fuertes y Corazones Saludables, in a nonprofit community organization serving rural Latinos. The intervention consisted of sixty-minute classes held twice weekly for 12 weeks and included 30 minutes of physical activity and 30 minutes of nutrition education. To assess efficacy, we used a one-group, pre⁻post design with overweight/obese, sedentary, middle-aged or older, Spanish-speaking rural Latinas (n = 15). Outcome measures included weight, height, body mass index (BMI), waist circumference, cardiorespiratory fitness, physical activity, dietary behavior, and self-efficacy for diet and physical activity. Process outcomes included attendance, end of class surveys, mid-program evaluation survey, and a post-program focus group. We calculated means and standard deviations, paproired t-tests, and Cohen's D effect size. Qualitative data were analyzed using qualitative description. Significant changes pre- to post-program included weight (-1.5 kg; p = 0.009), BMI (-0.6; p = 0.005), waist circumference (-3.0 cm; p = 0.008), 6-minute walk test (69.7 m; p < 0.001), frequency of sugar-added drink consumption (-0.7 servings; p = 0.008), fruit and vegetable intake (1.3 servings; p = 0.035), and physical activity self-efficacy (0.9 points; p = 0.022). Participants found the program motivating and enjoyable, and on average participants attended 62% of classes and fidelity was maintained. This pilot study suggests that this culturally adapted physical activity and nutrition program for rural Latinas shows promise in improving physical activity, diet, and obesity.
