Effects of the Strong Hearts, Healthy Communities Intervention on Functional Fitness of Rural Women.

ABSTRACT:

Purpose

The purposes of these analyses were to determine whether Strong Hearts, Healthy Communities (SHHC), a multilevel, cardiovascular disease risk reduction program for overweight, sedentary rural women aged 40 or older, led to improved functional fitness, and if changes in fitness accounted for weight loss associated with program participation.

Methods

Sixteen rural communities were randomized to receive the SHHC intervention or a control program. Both programs involved groups of 12-16 participants. The SHHC program met 1 hour twice a week for 24 weeks where participants engaged in aerobic exercise and progressive strength training. Program content addressed diet and social and environmental influences on heart-healthy behavior. The control group met 1 hour each month for 6 months, covering current dietary and physical activity recommendations. Objective measures of functional fitness included the 30-second arm curl, 30-second chair stand, and 2-minute step test. Self-reported functional fitness was measured by the Physical Functioning Subscale of the MOS Short Form-36 (SF-36 PF).

Findings

The SHHC program was associated with increased strength and endurance, as represented by greater improvement in the chair stand and step test; and with increased physical function, as represented by the SF-36 PF. Adjustment for change in aerobic endurance, as measured by the step test, accounted for two-thirds of the intervention effect on weight loss at the end of the intervention.

Conclusions

SHHC participants experienced improved performance on objective measures of functional fitness and self-reported measures of physical function, and changes in weight were partially accounted for by changes in aerobic fitness.

Project description:BackgroundCardiovascular disease is the leading cause of death in the United States and places substantial burden on the health care system. Rural populations, especially women, have considerably higher rates of cardiovascular disease, influenced by poverty, environmental factors, access to health care, and social and cultural attitudes and norms.Methods/designThis community-based study will be a two-arm randomized controlled efficacy trial comparing a multi-level, community program (Strong Hearts, Healthy Communities) with a minimal intervention control program (Strong Hearts, Healthy Women). Strong Hearts, Healthy Communities was developed by integrating content from three evidence-based programs and was informed by extensive formative research (e.g. community assessments, focus groups, and key informant interviews). Classes will meet twice weekly for one hour for 24 weeks and focus on individual-level skill building and behavior change; social and civic engagement are also core programmatic elements. Strong Hearts, Healthy Women will meet monthly for hour-long sessions over the 24 weeks covering similar content in a general, condensed format. Overweight, sedentary women 40 years of age and older from rural, medically underserved communities (12 in Montana and 4 in New York) will be recruited; sites, pair-matched based on rurality, will be randomized to full or minimal intervention. Data will be collected at baseline, midpoint, intervention completion, and six-month, one-year, and eighteen months post-intervention. The primary outcome is change in body weight; secondary outcomes include physiologic, anthropometric, behavioral, and psychosocial variables. In the full intervention, engagement of participants' friends and family members in partnered activities and community events is an intervention target, hypothesizing that there will be a reciprocal influence of physical activity and diet behavior between participants and their social network. Family members and/or friends will be invited to complete baseline and follow-up questionnaires about their health behaviors and environment, height and weight, and attitudes and beliefs.DiscussionStrong Hearts, Healthy Communities aims to reduce cardiovascular disease morbidity and mortality, improve quality of life, and reduce cardiovascular disease-related health care burden in underserved rural communities. If successful, the long-term goal is for the program to be nationally disseminated, providing a feasible model to reduce cardiovascular disease in rural settings.Trial registrationClinicalTrials.gov Identifier: NCT02499731 Registered on July 1, 2015.

Project description:IntroductionRural women have higher rates of cardiovascular disease than their nonrural counterparts, partially because of their social and environmental contexts. The study objective is to test a refined version of the multilevel Strong Hearts, Healthy Communities intervention, which used extensive process and outcome evaluation data from the original randomized trial to optimize effectiveness as measured by improved Simple 7 score, a composite measure of cardiovascular disease risk.Study designThe intervention was implemented in a 6-month, delayed intervention, community-randomized trial; control participants received the program following 24-week outcome assessment. The study was conducted in 2017-2018; data analysis occurred in 2018-2019.Setting/participantsThe study was conducted in 11 rural, medically underserved towns in New York. Participants were women aged ≥40 years who were either (1) obese or (2) overweight and sedentary.InterventionThe intervention group received 24 weeks of hour-long, twice-weekly classes including strength training, aerobic exercise, and skill-based nutrition- and health-related education, as well as civic engagement activities focused on healthy food and physical activity environments.Main outcome measuresMeasures included weight and height; blood pressure; blood cholesterol; blood glucose; and self-reported smoking, diet, and physical activity behaviors. Individual Simple 7 components were examined, and mixed linear regression analyses were used to examine change in Simple 7 score.ResultsA total of 182 participants were randomized. Compared with control participants, the intervention group had greater improvements in Simple 7 score (difference=1.03, 95% CI=0.44, 1.61, p<0.001) and 3 of the Simple 7 components (physical activity, healthy diet score, and BMI).ConclusionsThese findings highlight the importance of rigorously evaluating programs in real-world community settings and, when appropriate, revising and retesting interventions to optimize dissemination potential.Trial registrationThis study is registered at www.clinicaltrials.gov NCT03059472.

Project description:BACKGROUND:Women living in rural areas face unique challenges in achieving a heart-healthy lifestyle that are related to multiple levels of the social-ecological framework. The purpose of this study was to evaluate changes in diet and physical activity, which are secondary outcomes of a community-based, multilevel cardiovascular disease risk reduction intervention designed for women in rural communities. METHODS:Strong Hearts, Healthy Communities was a six-month, community-randomized trial conducted in 16 rural towns in Montana and New York, USA. Sedentary women aged 40 and older with overweight and obesity were recruited. Intervention participants (eight towns) attended twice weekly exercise and nutrition classes for 24?weeks (48 total). Individual-level components included aerobic exercise, progressive strength training, and healthy eating practices; a civic engagement component was designed to address social and built environment factors to support healthy lifestyles. The control group (eight towns) attended didactic healthy lifestyle classes monthly (six total). Dietary and physical activity data were collected at baseline and post-intervention. Dietary data were collected using automated self-administered 24-h dietary recalls, and physical activity data were collected by accelerometry and self-report. Data were analyzed using multilevel linear regression models with town as a random effect. RESULTS:At baseline, both groups fell short of meeting many recommendations for cardiovascular health. Compared to the control group, the intervention group realized significant improvements in intake of fruit and vegetables combined (difference: 0.6 cup equivalents per day, 95% CI 0.1 to 1.1, p?=?.026) and in vegetables alone (difference: 0.3 cup equivalents per day, 95% CI 0.1 to 0.6, p?=?.016). For physical activity, there were no statistically significant between-group differences based on accelerometry. By self-report, the intervention group experienced a greater increase in walking MET minutes per week (difference: 113.5 MET-minutes per week, 95% CI 12.8 to 214.2, p?=?.027). CONCLUSIONS:Between-group differences in dietary and physical activity behaviors measured in this study were minimal. Future studies should consider how to bolster behavioral outcomes in rural settings and may also continue to explore the value of components designed to enact social and environmental change.

Project description:BackgroundIn the United States, cardiovascular diseases (CVD) are the leading cause of death and disability in women. CVD-modifiable risk factors, including poor diet quality and inadequate physical activity, can be addressed through evidence-based interventions (EBIs). Strong Hearts Healthy Communities (SHHC) is an EBI that has demonstrated effectiveness in reducing CVD risk and improving health outcomes among rural white women. The aims of this study were to understand the general health, diet, and physical activity-related needs and goals of women living in an urban community, to inform the tailoring and adaptation of the SHHC EBI to an urban setting and more diverse population.MethodsFocus groups (FGs) were conducted with African American/Black and Hispanic/Latinx women in the Dallas metropolitan area who had a BMI ≥ 25 kg/m2 and engaged in ≤ 150 min per week of moderate physical activity. The data were coded using a team-based, deductive, and thematic analysis approach, that included multiple coders and in-depth discussions.ResultsFour FGs with a total of 18 participants (79% Black and 21% Latinx) were conducted, and three themes were developed: (1) participants had adequate knowledge and positive attitudes towards healthy living but faced many barriers to practicing healthy behaviors; (2) culturally-based beliefs and community practices exerted a strong influence on behaviors related to food and stress, revealing barriers to healthy eating and generational differences in stress and stress management; (3) participants desired a more individualized approach to nutrition and physical activity interventions that included familiar and enjoyable activities and social support centered around shared health goals.ConclusionsThe SHHC intervention and similar health programs for Black/African American and Hispanic/Latinx women in urban settings should emphasize individualized nutrition and practical skills for healthy eating with accessible, familiar, and enjoyable exercises. Additionally, stress management strategies should be culturally and generationally sensitive and social support, whether through family, friends, or other program participants, should be based on shared health goals.

Project description:BackgroundPhysical inactivity is a risk factor for numerous adverse health conditions and outcomes, including all-cause mortality. Aging rural women are at particular risk for physical inactivity based on environmental, sociocultural, and psychosocial factors. This study reports on changes in physical activity and associated factors from a multicomponent community-engaged intervention trial.MethodsStrong Hearts, Healthy Communities 2.0 (SHHC-2.0) was a 24-week cluster (community) randomized controlled trial building on the results from the previous trial of SHHC-1.0. Rural women (n = 182) aged 40 and over living in 11 rural communities in upstate New York were recruited. The intervention consisted of twice-weekly experiential classes focused on exercise, nutrition, and civic engagement. Physical activity outcomes included accelerometry and self-report as well as related psychosocial measures at midpoint (12 weeks) and post-intervention (24 weeks). Data were analyzed using multilevel linear regression models with the community as the random effect.ResultsCompared to participants from the control communities, participants in the intervention communities showed a significant increase in objectively measured moderate to vigorous intensity physical activity: at 12 weeks (increase of 8.1 min per day, P < 0.001) and at 24 weeks (increase of 6.4 min per day; P = 0.011). Self-reported total MET minutes per week also increased: at 12 weeks (increase of 725.8, P = 0.003) and 24 weeks (increase of 955.9, P = 0.002). Several of the psychosocial variables also showed significant positive changes.ConclusionsThe SHHC-2.0 intervention successfully increased physical activity level and related outcome measures. Modifications made based upon in-depth process evaluation from SHHC-1.0 appear to have been effective in increasing physical activity in this at-risk population.Trial registrationClinicaltrials.gov: NCT03059472.
