Vicarious Experience to Affect Physical Activity in Women: A Randomized Control Trial.

People compare themselves to others for self-evaluation, practical information, and motivation for healthy behaviors. The effect of active peer models on comparative thinking is unknown. The purpose of this 12-week, randomized, two-group pilot study was to evaluate the effect of a workplace peer modeling intervention on self-efficacy, motivation, and comparative thinking. The attention control group (ACG; n = 24) received general health information. The intervention group (n = 26) met with active peer models, received an exercise prescription and information. No significant group by time interaction effects were found. Comparisons on ability (how well am I doing), opinions (what should I think or believe), future self (think about my future), and modeling (be like someone else) all increased in the intervention group (n = 21) but decreased in the ACG (n = 22). Active peer models may support physical activity behavior change through specific lines of comparative thinking.

Perceptions of a Peer Modeling Workplace Physical Activity Intervention for Women.

A workplace physical activity (PA) study tested a novel use of peers to deliver the intervention. Peer models provided vicarious experience for living physically active lifestyles to a group of inactive women. The purpose of this study was to describe participants' perceptions of the peer modeling intervention. Nine women from the intervention group ( n = 26) participated in a 90-minute focus group. Qualitative description using thematic analysis was used to identify themes from the focus group transcript. Two themes about the intervention were "I am left wanting more" and "focus on food." Two themes about the peer models were "real people" and "it is doable." Focus group participants perceived the peer modeling PA intervention favorably; however, they desired more attention to healthy eating and more time with peer models. Replication of the study accounting for themes identified by focus group participants is needed to strengthen the peer modeling intervention.

Feasibility and Effect of a Peer Modeling Workplace Physical Activity Intervention for Women.

Most working women do not meet current guidelines for physical activity (PA). A 12-week pilot study tested a workplace, peer modeling PA intervention. Inactive female employees from a health system were randomized to an attention control group (ACG; n = 26) or an intervention group (IG; n = 26). The ACG received health information. The IG participated in six group sessions with an active peer model and received an exercise prescription and PA information. Pre and post measures were PA (ActiGraph), Estimated VO2max (cycle ergometer), resting heart rate (HR), glucose and lipids, and cardiovascular risk. Using hierarchical linear modeling, no significant group by time effects were found. Although PA increased in both groups, F( df = 1) = 11.4, p = .002, the IG had greater improvements in fitness (VO2max, HR) and cardiovascular risk (total cholesterol, triglyceride, low density lipoprotein [LDL], calculated risk score) compared with ACG. Results support repeating this intervention in a fully powered study.

A Qualitative Study of Experiences of Participants in Cardiac Rehabilitation.

PURPOSE: Maintenance of lifestyle changes after cardiac rehabilitation (CR) is suboptimal. In addition, partners of cardiac patients are invited to participate in CR educational sessions and implicitly expected to assist patients with their lifestyle changes. The purpose of this study was to qualitatively examine patient and partner perceptions of phase 2 CR 3 mo after completion of the program. METHODS: A purposive sample of 11 couples (patients post-heart surgery and their spouses) was interviewed following completion of CR. Semistructured, in-person interviews were conducted with patients and spouses separately. Data were analyzed using line-by-line coding to identify themes. RESULTS: Themes were identified in relation to program elements of CR. Exercise themes were as follows: (1) benefitted from exercise and (2) felt held back. Education themes were as follows: (1) received basic education and (2) needed more personalized information. CR environment themes were as follows: (1) developed confidence; (2) made social comparisons; and (3) helped to have partner there. CONCLUSION: Overall, participant perceptions of exercise, education, and the CR environment were very positive. Nevertheless, there is a need to improve educational efforts within CR to rely less on "canned" presentations and more on participants developing their own self-management methods to maintain a healthy lifestyle after CR.

Changes over time in caregiving demand and difficulty in spousal caregivers of coronary artery bypass graft surgery patients.

Patients who undergo coronary artery bypass graft (CABG) surgery are often dependent on spouses or family members for care during their recovery. The purpose of this study was to examine changes over time in spousal caregivers of coronary artery bypass graft (CABG) patients in caregiving demand and caregiving difficulty and to identify the key demands and difficulties at each time point. Spouses (n=34) of CABG patients comprised the sample. Caregiving demand and caregiving difficulty were measured using the Caregiving Burden Scale at three time points (baseline [early hospital discharge] and 3 and 6months later) and analyzed using repeated measures analysis of variance. Mean scores of each item were used to identify the top four caregiving demands and difficulties at each time point. There was a significant decrease over time in caregiving demands (F [1.696]=13.62, p<0.001) and caregiving difficulties (F [1.613]=4.52, p=0.02). The most demanding and/or difficult caregiving activities at all time points were providing social support, managing behavior problems, taking on additional household tasks, and monitoring symptoms. Early in recovery, providing transportation was a top ranked demand and difficulty. Later in recovery (3 and 6months), managing finances became a top ranked demand and difficulty. In conclusion, caregiving demands and difficulties declined significantly over six months for the caregivers in this study. These results indicate that caregiving demands and difficulties change over time and ongoing assessments of spouses and family members are needed to help them manage the caregiving situation.

Couples' Experiences With Healthy Lifestyle Behaviors After Cardiac Rehabilitation.

PURPOSE: Many cardiac patients discontinue heart-healthy eating and physical activity (PA) behaviors in the months following cardiac rehabilitation (CR). Involving the spouse in CR with the patient may be 1 strategy to increase the maintenance of these behaviors after CR. Assisting patients and spouses with the maintenance of healthy eating and PA behavior following CR begins with a better understanding of the couple-focused factors, impacting their experiences with these behaviors. The purpose of this study was to qualitatively examine couple-focused facilitators and barriers to maintaining changes in healthy eating and PA behavior from the perspectives of both cardiac patients and their spouses following phase 2 CR. METHODS: A purposive sample of 11 couples (patients undergoing postcoronary artery bypass graft surgery and their spouses) were selected from a larger randomized control trial. Semistructured, in-person interviews were conducted with patients and their spouses separately following CR. Data were analyzed using line-by-line coding to identify facilitator and barrier themes. RESULTS: Two couple-focused barrier themes emerged: unnegotiated situations and unshared behaviors. Two couple-focused facilitator themes emerged: supportive exchanges and partnerships. CONCLUSION: These findings will help guide interventions targeting changes in diet and PA behavior in both patients and their spouses through minimizing unnegotiated situations, fostering supportive exchanges, and creating a partnership for the couple to work together on shared diet and PA goals. Targeting both patients and their spouses may be an innovative and effective way to intervene to increase adherence to healthy eating and PA behaviors post-CR.

Social Support, Parenting Competence, and Parenting Satisfaction Among Adolescent, African American, Mothers.

This secondary analysis explored how social support changed during the first 6 months postpartum and examined the relationships among social support, parenting competence, and parenting role satisfaction. Single, low-income, adolescent, new mothers ( N = 34) completed measures of perceived parenting competence, parenting role satisfaction, and four types of received social support (emotional, informational, tangible, problematic) from the entire social network at 1 week, 6 weeks, 3 months, and 6 months postpartum. Results indicated that social support did not change over time. Emotional, informational, and tangible social support were significantly correlated, concurrently and predictively, with perceived competence and satisfaction at most data collection points. Future social support intervention studies using social support as a modifiable variable with this high-risk group of African American adolescent new mothers are advocated. Health care professionals are encouraged to examine existing social support within these mothers' identified family units.

Are Heart Failure and Coronary Artery Bypass Surgery Patients Meeting Physical Activity Guidelines?

PURPOSE: The purpose of this study was to describe subjective and objective physical activity (PA) levels of two groups of cardiovascular patients who were either post-coronary artery bypass graft (CABG) surgery or diagnosed with heart failure (HF). DESIGN: A descriptive comparative design was used for this secondary analysis of data from two prior studies. METHODS: A convenience sample of 62 outpatients was used to examine PA objectively (Actiheart accelerometer) and subjectively (PA interview). FINDINGS: Objectively, 33% of CABG patients and no HF patients met PA recommendations of ≥ 150 min/week. Subjectively, 56% of CABG and 38% of HF patients reported meeting PA recommendations. CONCLUSIONS: Few patients in the current study met PA recommendations. CLINICAL RELEVANCE: Innovative rehabilitation nursing practice strategies are needed (e.g., use of activity trackers, making PA a vital sign) to assist patients in gaining the knowledge and skills to be more active and adhere to PA recommendations.

Cardiovascular risk factors among college students: Knowledge, perception, and risk assessment.

OBJECTIVE: To assess college students' knowledge and perception of cardiovascular risk factors and to screen for their cardiovascular risks. PARTICIPANTS: The final sample that responded to recruitment consisted of 158 college students from a midwestern university. METHODS: A cross-sectional, descriptive study was performed using convenience sampling. RESULTS: College students were knowledgeable about cardiovascular risk factors but did not perceive themselves at risk for cardiovascular disease (CVD). Knowledge of cardiovascular risk factors was correlated with the lifetime risk estimates (ρ = .17, p = .048), and perception of cardiovascular risk was positively associated with 30-year CVD risk estimates (ρ = .16, p = .048). More than 50% of the participants had 1 or more cardiovascular risk factors. CONCLUSIONS: High knowledge level of cardiovascular risk factors was not sufficient to lower cardiovascular risks within this study population, but changing perception of cardiovascular risk factors may play a bigger role in reducing long-term cardiovascular risks.

Social Support and Psychosocial Well-being Among Low-Income, Adolescent, African American, First-Time Mothers.

AIMS: The aims of this study are to describe for single, low-income, adolescent, African American new mothers how (1) primary sources of social support changed over time, (2) the level of social support (emotional, informational, tangible, and problematic) from these primary sources changed over time, and (3) social support from the primary supporter was associated with mothers' psychosocial well-being (self-esteem and loneliness) over time. DESIGN: A secondary analysis was conducted of data from a previous social support intervention study. SAMPLE: The sample consisted of 35 single, low-income, adolescent (mean [SD] age, 18.3 [1.7] years), African American new mothers. METHODS: Mothers completed social support, self-esteem, and loneliness instruments at 1 and 6 weeks and 3 and 6 months postpartum. RESULTS: Most mothers (64.7%) had changes in their primary social support provider during the first 6 months postpartum. The combination of the adolescent's mother and boyfriend provided the highest level of support, no matter the type, relative to any other source of support. At every time point, positive correlations were found between emotional support and self-esteem and between problematic support and loneliness. CONCLUSION: Single, low-income, African American, adolescent new mothers are at risk for not having a consistent source of support, which may lead to lower self-esteem and greater loneliness. IMPLICATIONS: Clinical nurse specialists could facilitate care guidelines for these new mothers to identify their sources of support at each home visit and advocate for the adolescent's mother and boyfriend to work together to provide support. Bolstering the mothers' natural sources of support can potentially improve self-esteem and reduce loneliness. Improvement in these sources of support could prevent a decline in the mothers' psychosocial well-being. Development and testing support interventions are advocated; findings could guide clinical nurse specialists in addressing these new mothers' needs.

Behavior-Specific Influences for Physical Activity Among African American Women.

The purpose of this study was to describe physical activity (PA) behaviors and physical functioning of prehypertensive and Stage I hypertensive African American Women (AAW) and to examine the relationships between PA behavior, physical functioning, personal factors, and behavior-specific influences. Pender's Health Promotion Model was the conceptual framework for the study. A cross-sectional design and convenience sample were used. The PA domain where the greatest amount of time was spent was in work-related activity, followed by household, leisure time, and transportation activity. Personal factors most strongly correlated to lower PA were greater body mass index and waist circumference. AAW perceived moderate barriers to PA and minimal family and friend social support for PA. Future interventions need to focus on removing barriers to and improving social support for PA among AAW.

Spousal Caregivers of Coronary Artery Bypass Surgery Patients: Differences between Caregivers with Low vs. High Caregiving Demands.

PURPOSE: Compared to non-caregivers, caregivers have higher rates of depressive symptoms, caregiver strain, less mutuality, and health care visits. However, few investigators have examined family caregivers after coronary artery bypass (CAB) surgery. The purpose of this study was to examine differences in caregiving difficulties, mutuality (i.e., open communication; avoiding sad thoughts), and depressive symptoms based on low vs. high caregiving demands among spousal caregivers. DESIGN: A descriptive, comparative design was used to examine 33 spousal caregivers of CAB surgery patients (16 in low and 17 in high caregiving demand groups). METHODS: Measures included: Caregiving Burden Scale, Mutuality and Interpersonal Sensitivity Scale, and Patient Health Questionnaire-9. Groups were compared using Mann-Whitney U statistics. FINDINGS: It was found that caregivers with high caregiving demands reported more caregiving difficulties and more open communication about the surgery compared to caregivers with low demands. CONCLUSION: Caregivers with greater caregiving demands may need additional support to assist them with the caregiving situation. CLINICAL RELEVANCE: Priority should be given to family caregivers, who take care of patients in cardiac rehabilitation, with higher caregiving demand.

Eating Self-Regulation in Overweight and Obese Adults: A Concept Analysis.

BACKGROUND: Poor eating behaviors greatly influence the development of becoming overweight or obese. Learning to better self-regulate eating is one area in which individuals can positively influence their own health. PURPOSE: The purpose of this concept analysis is to provide an in-depth analysis of the concept eating self-regulation as it pertains to overweight and obese adults using Walker and Avant's method. RESULTS: The definition for eating self-regulation formulated as a result of this concept analysis and based on the critical attributes is the ability to initiate goal-related behaviors, to consistently self-monitor dietary intake, to regularly apply willpower to resist temptations, to self-evaluate where one stands in relationship to goal attainment, and finally to maintain motivation to positively change eating behaviors. Cognitive restraint, moderation, mindfulness, disinhibition, delayed gratification, emotions and moods, self-efficacy, social support, the environment, and physical activity are the antecedents that may influence eating self-regulation. CONCLUSION: Examining an individual's weight, body mass index, lipid levels, or blood pressure are some ways to determine if self-regulation of eating behavior is achieved. With a consistent definition of self-regulation and a better understanding of the critical factors that influence eating behaviors, research can better explore how to help individuals change their eating behaviors more effectively.

Motivational Factors Predict Weight Loss in Rural Adults.

OBJECTIVE: The objective was to: (a) describe the changes over time in motivational factors of weight loss and (b) to examine predictors of weight loss in rural adults enrolled in a weight loss program. DESIGN AND SAMPLE: A longitudinal study was conducted in a convenience sample of 50 adults recruited from a rural Young Men's Christian Association. MEASURES: Questionnaires were completed at baseline (preprogram), 1, 2 and 3 months (end of program). RESULTS: Mean age was 42.4 (SD ± 11.8); 84% were female and mean BMI was 32.9 (SD ± 4.3). Individuals lost an average of 12.1 pounds. Barriers to healthy eating decreased significantly over time (p < .001). Significant predictors of weight loss included gender (ß = .501, p < .001), and the amount of change between baseline and 3 months in controlled regulation (ß = .270, p < .05), barriers to healthy eating (ß = -0.225, p < .05), and physical activity (ß = .238, p < .05) explaining 45% of the variance (F[(8, 41] = 5.92, p < .001) in weight loss. CONCLUSIONS: Rural adults were more likely to lose weight if they had higher levels of controlled regulation, if barriers were reduced, and if physical activity levels increased during the 3-month weight loss program.

Functional Status and Search for Meaning After Percutaneous Coronary Intervention.

The purpose of this study was to determine the differences in the search for meaning and functional status (psychological and physical) between persons who undergo percutaneous coronary intervention and have recurrent angina symptoms and those who do not have recurrent symptoms. Participants (224; 147 male, 77 female) who underwent PCI completed the following study materials: Meaning in Heart Disease instrument, Hospital Anxiety and Depression Scale, and SF36v2™. Persons with recurrent angina symptoms (40% of the sample) were more likely to have higher disrupted meaning, greater anxiety, greater depression, lower physical functioning, and greater use of meaning-based coping (searching for answers and refocusing global meaning) compared with individuals without recurrent symptoms. Interventions are needed to identify the risk of recurrent symptoms after percutaneous coronary intervention and provide coping and cognitive behavioral interventions focused on managing the psychological and physical disruptions.

Low-Income, African American, Adolescent Mothers' Depressive Symptoms, Perceived Stress, and Social Support.

The purpose of this descriptive repeated-measures study was to describe depressive symptom patterns and report changes over time in levels of perceived stress and social support depending on patterns of depressive symptoms in single, low-income, African American, adolescent mothers during the initial, 6-month postpartum period. Thirty-five adolescent subjects between the ages of 16 and 22 years old were recruited at health care clinics in two Midwestern cities. Data collections by advanced practice nurses were completed at 1 week, 6 weeks, 3 months, and 6 months postpartum at mothers' homes. Established instruments were used to measure depressive symptoms, perceived stress and social support. Results indicated 63% of adolescent mothers' experienced depressive symptoms sometime during this transition period and 11.4% of these subjects had depressive symptoms at all 4 time points. Depressive symptoms were associated with perceived stress at each time point. Emotional support was inversely associated with depressive symptoms at 2 of the 4 time points. Depressive symptoms and problematic support were significantly related at 3 months and 6 months. Although single, low-income, African American, adolescent mothers are considered a high risk group, some are at even greater risk. This extremely high risk group have depressive symptoms throughout the first 6 months postpartum with the highest level of perceived stress and the most variability in social support relative to groups that were never depressed or were in and out of depression. More studies are needed to understand how to best help these high risk adolescents successfully transition to motherhood.

Reducing cardiovascular risk in spouses of cardiac patients: a randomized controlled trial.

Few studies have examined risk-reducing interventions in spouses of coronary artery bypass patients. This study examined the effects of the Partners Together in Health (PaTH) intervention versus usual care on cardiovascular risk factors. Spouses in the experimental group (n = 17/group) attended cardiac rehabilitation with patients and made the same physical activity and healthy eating changes as patients. Spouses in the usual care group attended educational classes with patients. Spouses' 30-year cardiovascular risk was calculated using the Lifetime Risk Scale before and after cardiac rehabilitation (3 months), and at 6 months. Spouses in both groups significantly reduced 30-year risk scores at 3 and 6 months. Exercise was the key ingredient in lowering risk. There was a trend toward reduction in systolic blood pressure and an increase in high-density lipoprotein cholesterol in both groups. Although there were no group differences, having spouses participate in cardiac rehabilitation with the patient was effective for reducing spouses' cardiovascular risk.

Effects of partners together in health intervention on physical activity and healthy eating behaviors: a pilot study.

BACKGROUND: Despite proven efficacy of cardiac rehabilitation (CR) in helping patients initiate physical activity and healthy eating changes, less than 50% of CR participants maintain changes 6 months later. OBJECTIVE: The objective of this feasibility study was to test the Partners Together in Health (PaTH) intervention versus usual care in improving physical activity and healthy eating behaviors in coronary artery bypass graft surgery patients and their spouses. METHODS: An experimental, 2-group (n = 17 couples/group), repeated-measures design was used. Coronary artery bypass surgery patients in both groups participated in phase II outpatient CR. Spouses in the PaTH group attended CR with the patient and were asked to make the same physical activity and healthy eating changes as patients did. Spouses in the usual care attended educational classes with patients. It was theorized that "2 persons would be better than 1" at making changes and sticking with them in the long-term. Physical activity behavior was measured using the Actiheart accelerometer; the activity biomarker was an exercise tolerance test. Eating behavior was measured using 3-day food records; the biomarker was the lipid profile. Data were collected at baseline (entrance in CR), at 3 months (post-CR), and at 6 months. Changes over time were examined using Mann-Whitney U statistics and effect sizes. RESULTS: The PaTH intervention was successful primarily in demonstrating improved trends in healthy eating behavior for patients and spouses. No differences were found between the PaTH and usual care patients or spouses at 3 or 6 months in the number of minutes per week of physical activity. By 6 months, patients in both groups were, on average, below the national guidelines for PA recommendations (≥150 min/wk at >3 metabolic equivalents). CONCLUSIONS: The couple-focused PaTH intervention demonstrated promise in offsetting the decline in dietary adherence typically seen 6 months after CR.

Health promotion text blasts for minority adolescent mothers.

PURPOSE: To examine use of technology for delivering a health promotion intervention via text blasts in single, low-income, adolescent, minority mothers and to describe their perceptions and experiences with the intervention. STUDY DESIGN AND METHODS: A qualitative descriptive design was used for this study. Health promotion information was sent weekly in the form of text blasts and/or pictures to five mothers during the first 6 months postpartum. Topics included promotion of breastfeeding, effects of breast milk on infant growth and development, information about infant immunizations, and reminders about infant and maternal follow-up and well-being. Qualitative interviews occurred monthly with mothers about their perceptions and experiences with the health promotion intervention and their health promotion behaviors. Data were analyzed using qualitative analytic techniques to generate themes from the mothers' interviews. RESULTS: Four themes emerged: (a) Trustworthy Support System, (b) Overcoming Barriers to Health Promotion, (c) Parenting Validation, and (d) Preferred Mode of Communication. All mothers used breast milk through 6 months postpartum and were adherent with childhood immunizations and maternal and infant follow-up appointments, unlike lower proportions in the general population. CLINICAL IMPLICATIONS: Health promotion text blasts can improve single, low-income, adolescent, minority mothers' health behavior outcomes such as adherence with recommended immunizations for their infants, breastfeeding success, and recommended maternal and infant healthcare visits. Further, it is the preferred mode of communication for these mothers. Future studies are needed for examining the use of technology to deliver healthcare to a larger sample of minority adolescent mothers.
