Physical activity counseling intervention to promote weight loss in overweight rural women

Physical activity promotion in rural health care settings: A rapid realist review

•

Rural communities have a unique health care and physical activity context.

•

We conducted a rapid realist review in partnership with knowledge users.

•

Check-ins from health care providers may lead to intervention success and are valued by participants.

•

A method for tracking progress is an important component of interventions delivered in rural health care settings.

Physical activity promotion in health care settings is poorly understood and has limited uptake among health care providers. The environmental and health care context of rural communities is unique from urban areas and may interact to influence intervention delivery and success. The aim of this rapid realist review was to synthesize knowledge related to the promotion of physical activity in rural health and social care settings. We searched Medline EBSCO, CINAHL, PsychINFO, and SPORTDiscus for relevant publications. We included qualitative or quantitative studies reporting on an intervention to promote physical activity in rural health (e.g., primary or community care) or social (e.g., elder support services) care settings. Studies without a rural focus or well-defined physical activity/exercise component were excluded. Populations of interest included adults and children in the general population or clinical sub-population. Intervention mechanisms from included studies were mapped to the Behaviour Change Wheel (capability, opportunity, motivation (COM-B)). Twenty studies were included in our review. Most interventions focused on older adults or people with chronic disease risk factors. The most successful intervention strategies leading to increased physical activity behaviour included wearable activity trackers, and check-ins or reminders from trusted sources. Interventions with mechanisms categorized as physical opportunity, automatic motivation, and psychological capability were more likely to be successful than other factors of the COM-B model. Successful intervention activities included a method for tracking progress, providing counselling, and follow-up reminders to prompt behaviour change. Cultivation of necessary community partnerships and adaptations for implementation of interventions in rural communities were not clearly described and may support successful outcomes in future studies.

Physical activity change after a promotora-led intervention in low-income Mexican American women residing in South Texas

BACKGROUND

The purpose of this study was to determine physical activity (PA) preferences associated with increases in moderate-to-vigorous physical activity (MVPA) and decrease in sedentary time in Mexican American (MA) women participating in a Promotora (community health worker)-led intervention on the U.S.-Mexico border.

METHODS

Enlace ('to link' in Spanish) was a randomized clinical trial to increase PA in low-income, MA women living in South Texas on the U.S.-Mexico border. A total of 620 participants were recruited into the study. The primary outcome was increase in moderate to vigorous physical activity (MVPA) using the Actigraph GT3X 16 Mb accelerometer. A modified version of the Community Health Activities Model Program for Seniors Physical Activity (CHAMPS) instrument was used to predict MVPA. Adjusted and unadjusted logistic regression models predicted change in MVPA by change in CHAMPS activities. ANOVA analysis determined the variance explained in change in MVPA by change in time engaged in activity. Individual effect sizes were then calculated for significant activity type change on MVPA increase.

RESULTS

There were significant increases in all CHAMPS activities except aerobic machines and errand walking. An increase in leisure walking (O.R. = 2.76, p = .046), errand (O.R. = 3.53, p = .051), and brisk walking (O.R. = 4.74, p = .011), dance (O.R. = 8.22, p = .003), aerobics class (O.R. = 32.7, p = .001), and light housework (O.R. = 6.75, p = .000), were associated with a decrease in sedentary time. Significant effect sizes for MVPA were observed for jogging (1.2, p = .050), general exercise (1.6, p = .024), and other exercise not specified (2.6, p = .003). Significant effect sizes for sedentary time were detected for leisure time (.031, p = .036), errands (.017, p = .022), brisk walking (.022, p = .003), dance (.042, p = .005), and aerobics class (.013, p = .009).

DISCUSSION

Participants who engaged in walking and aerobic activities through this intervention significantly increased their engagement in MVPA and decreased their sedentary time. These findings are novel, since preferences have not been examined in relation to MVPA or sedentary time in MA women.

CONCLUSION

PA preferences need to be considered when aiming to promote activities that reduce sedentary time and increase PA participation among marginalized groups, such as MA women.

Discrepancy in Motivation for Weight Loss and Exercise in Rural Patients

OBJECTIVES

We explored the extent to which discrepancy between motivation for weight loss and exercise is related to obesity among rural patients with chronic disease, and identified the psychosocial correlates of this discrepancy.

METHODS

497 patients with diabetes and/or hypertension were recruited from a network of Federally Qualified Health Centers in the rural South and completed a battery of assessments.

RESULTS

Most persons in the sample (83.1%) were overweight and 65.0% were obese. For motivation for change, 70.8% reported being in the Action stage or higher for weight loss, whereas only 24.9% reported being in the Action stage or higher for motivation for exercise. When controlling for age, education level, income, sex, and race/ethnicity, individuals who were motivated for weight loss but not exercise were twice as likely to be obese (p = .005). Race and sex were significantly associated with this discrepancy, with African-American patients 1.7 times as likely (p = .05) and women 2.3 times as likely to be discrepant (p = .001).

CONCLUSIONS

Findings underscore the importance of focusing not simply on weight loss among rural patients with chronic disease, but rather to incorporate specific activities designed to build simultaneous motivation for engaging in exercise.

Higher Motivation for Weight Loss in African American than Caucasian Rural Patients with Hypertension and/or Diabetes

OBJECTIVE

To examine the relationship between race/ethnicity and motivation for weight loss and motivation for exercise among patients with chronic disease.

DESIGN

Cross-sectional.

SETTING

Our study took place within a network of federally qualified health centers (FQHCs) in the rural southern United States.

PATIENTS OR PARTICIPANTS

463 active FQHC patients with diabetes and/or hypertension identifying as African American, White Hispanic, or non-Hispanic White participated in our study.

MAIN OUTCOME MEASURES

Primary outcomes were assessed using standardized measures of motivation for a) weight loss; and b) hypertension per the Transtheoretical Model.

RESULTS

Multivariate logistic regression revealed that, when controlling for age, sex, education status, employment status, poverty, comorbidity, and weight status, there were no significant differences in motivation for exercise among the different racial/ethnic groups (P=.361). However, when controlling for the same factors, there was a significant difference in motivation for weight loss, with African American participants more than twice as likely as non-Hispanic White participants to be motivated to lose weight (ORADJ = 2.430, P=.002).

CONCLUSIONS

Our study suggests that, among rural patients with obesity-related chronic disease, there is a significant variation in motivation to lose weight between racial/ethnic groups. This underscores the importance of culturally tailoring interventions and in considering motivation for change when promoting weight loss behaviors. Additional implications for intervention development and delivery are discussed.

A Peer-Led HIV Medication Adherence Intervention Targeting Adults Linked to Medical Care but without a Suppressed Viral Load

BACKGROUND

Non-adherence to antiretroviral (ART) treatment remains a prevalent problem even among the segment of the U.S. HIV population that is 'linked' to medical care.

METHODS

Controlled pilot feasibility study with ART experienced adult patients (n = 20) linked to HIV medical care without suppressed viral load. Patients were randomized to a peer-led HIV medication adherence intervention named `Ready' or a time equivalent `healthy eating' control arm. Lay individuals living with HIV were trained to facilitate `Ready'.

RESULTS

Patients had been prescribed a mean of three prior ART regimens. The group randomized to `Ready' had significantly improved adherence. MEMS and pharmacy refill data correlated with viral load log drop. Higher readiness for healthful behavior change correlated with viral load drop and approached significance.

CONCLUSION

A peer-led medication adherence intervention had a positive impact among adults who had experienced repeated non-adherence to HIV treatment. A larger study is needed to examine intervention dissemination and efficacy.
