ABSTRACT
Obesity is a recognized public health epidemic with a prevalence that continues to increase dramatically in nearly all populations, impeding progress in reducing incidence rates of cardiovascular disease. Over the past decade, obesity science has evolved to improve knowledge of its multifactorial causes, identifying important biological causes and sociological determinants of obesity. Treatments for obesity have also continued to develop, with more evidence-based programs for lifestyle modification, new pharmacotherapies, and robust data to support bariatric surgery. Despite these advancements, there continues to be a substantial gap between the scientific evidence and the implementation of research into clinical practice for effective obesity management. Addressing barriers to obesity science implementation requires adopting feasible methodologies and targeting multiple levels (eg, clinician, community, system, policy) to facilitate the delivery of obesity-targeted therapies and maximize the effectiveness of guideline-driven care to at-need patient populations. This scientific statement (1) describes strategies shown to be effective or promising for enhancing translation and clinical application of obesity-based research; (2) identifies key gaps in the implementation of obesity science into clinical practice; and (3) provides guidance and resources for health care professionals, health care systems, and other stakeholders to promote broader implementation and uptake of obesity science for improved population-level obesity management. In addition, advances in implementation science that hold promise to bridge the know-do gap in obesity prevention and treatment are discussed. Last, this scientific statement highlights implications for health research policy and future research to improve patient care models and optimize the delivery and sustainability of equitable obesity-related care.

Family caregivers are at high risk of psychological distress and low sleep efficiency resulting from their caregiving responsibilities. Although psychological symptoms are associated with sleep efficiency, there is limited knowledge about the association of psychological distress with variations in sleep efficiency. We aimed to characterize the short- and long-term patterns of caregivers' sleep efficiency using Markov chain models and compare these patterns between groups with high and low psychological symptoms (i.e., depression, anxiety, and caregiving stress). Based on 7-day actigraphy data from 33 caregivers, we categorized sleep efficiency into three states, < 75% (S1), 75-84% (S2), and ≥ 85% (S3), and developed Markov chain models. Caregivers were likely to maintain a consistent sleep efficiency state from one night to the next without returning efficiently to a normal state. On average, it took 3.6-5.1 days to return to a night of normal sleep efficiency (S3) from lower states, and the long-term probability of achieving normal sleep was 42%. We observed lower probabilities of transitioning to or remaining in a normal sleep efficiency state (S3) in the high depression and anxiety groups compared to the low symptom groups. The differences in the time required to return to a normal state were inconsistent by symptom levels. The long-term probability of achieving normal sleep efficiency was significantly lower for caregivers with high depression and anxiety compared to the low symptom groups. Caregivers' sleep efficiency appears to remain relatively consistent over time and does not show rapid recovery. Caregivers with higher levels of depression and anxiety may be more vulnerable to sustained suboptimal sleep efficiency.

BACKGROUND: Chronic stress is associated with promotion of inflammation and development of metabolic syndrome, as well as deterioration of diet quality. Inflammation can be modified by changes in dietary intake. OBJECTIVE: The aim of this study was to test the hypothesis that diet quality mediates the relationship of chronic stress with inflammation in patients with metabolic syndrome. METHODS: Participants with metabolic syndrome (n = 73, 62 ± 12 years old, 71% female) completed questionnaires on chronic stress (Perceived Stress Scale-10) and diet quality (Healthy Eating Index-2020). The Perceived Stress Scale-10 was dichotomized. The Healthy Eating Index-2020 score was used as a continuous variable, and higher scores indicate better diet quality. Inflammation was assessed using plasma high-sensitivity C-reactive protein (log-transformed). We used PROCESS in SPSS to test the hypothesis. RESULTS: Patients in the higher stress group had lower Healthy Eating Index-2020 scores (worse diet quality) than those in the lower stress group (57 ± 13 vs 64 ± 10, P = .01). Diet quality mediated the relationship between chronic stress and inflammation (indirect effect, 0.211; 95% bootstrap confidence interval, 0.006-0.496). Higher stress was associated with lower diet quality (effect, -7.152; 95% confidence interval, -13.168 to -1.137) that was associated with increased inflammation (effect, -0.030; 95% confidence interval, -0.052 to -0.007). CONCLUSIONS: Our findings show the important role of diet quality in the relationship of chronic stress with inflammation in patients with metabolic syndrome. Healthcare providers should encourage patients with higher stress to improve diet quality, which can decrease inflammation.
ABSTRACT
BACKGROUND: Health-related quality of life (HRQoL) is poor in patients with heart failure. Psychological (ie, depressive symptoms [DS], anxiety, and perceived control) and physical (ie, functional status) factors are associated with HRQoL. The dynamic relationships among these variables and their impact on HRQoL remain unclear, limiting the ability to design effective interventions. PURPOSE: Our aim was to evaluate a moderated mediation model, in which the association between perceived control and HRQoL was hypothesized to be mediated by DS and anxiety in the presence of a moderator, functional status. METHODS: Patients (N = 426) with heart failure completed the Control Attitudes Scale-Revised to measure perceived control, Duke Activity Status Index for functional status, Patient Health Questionnaire-9 for DS, Brief Symptom Inventory for anxiety, and Minnesota Living with Heart Failure Questionnaire for HRQoL. We performed a moderated parallel mediation analysis. RESULTS: Higher levels of perceived control were associated with better HRQoL through lower levels of anxiety and DS in the presence of functional status (index of moderated mediation for DS, b = 0.029; 95% confidence interval, 0.016-0.045; for anxiety: b = 0.009, 95% confidence interval, 0.002-0.018). The effect of perceived control on psychological symptoms was stronger at low and moderate functional statuses; however, this effect diminished with increasing functional status. CONCLUSION: Functional status moderated the indirect effects of perceived control on HRQoL through DS and anxiety in patients with heart failure. Efforts to improve HRQoL by targeting perceived control may be more effective when considering DS and anxiety in patients with low to moderate levels of functional status.
ABSTRACT
BACKGROUND: The Patient Activation Measure (PAM) is used clinically and in research to measure an individual's knowledge, skills, and confidence related to their health management engagement. Despite the use of "patient" in the title, the instrument can be used in nonpatient populations. A group at high risk for low activation concerning their own health is family caregivers of patients with chronic illnesses. The psychometric properties of the PAM have not been established in family caregivers. OBJECTIVES: This study aimed to examine the psychometric properties of the PAM 10-item version (PAM-10) in a sample of family caregivers of patients with chronic illnesses. Our focus was on family caregivers' health activation of their own healthcare needs. METHODS: We evaluated the internal consistency reliability of the PAM-10 in a sample of 277 family caregivers. Item-total correlations and interitem correlations were used to assess item homogeneity. Construct validity of the PAM-10 was examined using exploratory factor analysis and testing hypotheses on known relationships. RESULTS: The PAM-10 demonstrated adequate internal consistency. Item-total correlation coefficients and interitem correlation coefficients were acceptable. Construct validity of the instrument was supported. Factor analysis yielded two factors that explained 62.3% of the variance in the model. Lower levels of depressive symptoms were significantly associated with better activation, providing evidence of construct validity. Caregivers with high activation levels were significantly more likely to engage in and adhere to self-care behaviors such as regular exercise, eating a healthy diet, and engaging in stress reduction strategies. DISCUSSION: This study demonstrated that the PAM-10 is a reliable and valid measure for family caregivers of patients with chronic illnesses to measure caregivers' health activation of their own healthcare needs.

BACKGROUND: Family caregivers are at a high risk for low quality of life due to caregiving-related stress. Caregivers' stress is commonly assessed using self-reported measures, which reflect relatively subjective and long-term stress related to caregiving, but objective biological markers of stress are rarely used for caregivers. The purposes of this study were (1) to determine whether caregiver characteristics were associated with stress assessed using a stress biomarker (serum cortisol) and a self-reported caregiving distress measure (Caregiver Burden Inventory) and (2) to determine the predictability of both stress measures for quality of life in caregivers of patients with heart failure. METHODS: Taiwanese family caregivers (N = 113; mean age, 54.5 years; 70.8% female) of patients with heart failure completed surveys including caregiving distress and quality of life measured by the Caregiver Burden Inventory and the Short Form-36 (physical and psychological well-being subscales), respectively, and provided blood samples for serum cortisol. Independent t tests, correlation, and hierarchical regression were conducted. RESULTS: Single caregivers had higher serum cortisol levels than married caregivers (P = .002). Men had significantly higher serum cortisol levels than women (P = .010), but men reported lower caregiving distress than women (P = .049). Both serum cortisol (ß = -0.32, P = .012) and caregiving distress (ß = -0.29, P = .018) were significant predictors of quality of life in the physical well-being scale while controlling for caregivers' characteristics and depressive symptoms. Serum cortisol (ß = -0.28, P = .026) and caregiving distress (ß = -0.25, P = .027) also predicted quality of life in the psychological well-being scale. CONCLUSIONS: Serum cortisol and self-reported caregiving distress have similar predictability for quality of life in family caregivers of patients with heart failure. Reducing stress and caregiving distress is critical to improving quality of life in this population.
ABSTRACT
BACKGROUND: Clinicians and researchers often assume that symptom burden is associated with self-care management (SCM) in patients with heart failure (HF). However, that association is often not borne out in simple regression analyses and may be because another variable mediates the association. Fatalism is an appropriate candidate for mediation and is the belief that circumstances are predetermined without opportunity for control by individuals. OBJECTIVE: Our objective was to determine whether fatalism mediated the relationship of symptom burden with SCM among adults with HF. METHODS: We conducted a secondary analysis (N = 95) from a clinical trial. We used Self-care of HF Index to measure SCM, the Memorial Symptom Assessment Scale-HF for symptom burden, and the Cardiovascular Disease Fatalism Instrument to measure fatalism. We used the PROCESS macro to evaluate mediation. RESULTS: Symptom burden was not directly associated with SCM (effect coefficient [C'] = 0.0805; 95% confidence interval, -0.048 to 0.209; P = .217). There was, however, an indirect pathway between symptom burden and SCM through fatalism (ab = -0.040; 95% confidence interval, -0.097 to -0.002). Those with higher symptom burden were more fatalistic (a = 0.004, P = .015), and greater fatalism was associated with worse SCM (b = -9.132, P = .007). CONCLUSION: Symptom burden, not directly associated with SCM, is associated through the mediator of fatalism. Interventions to improve SCM should include strategies to mitigate fatalistic views. Self-care management interventions should focus on promoting internal locus of control or increasing perceptions of perceived control to decrease fatalism and improve engagement in self-care.
ABSTRACT
BACKGROUND: Depressive symptoms are substantial among stroke survivors and their caregivers in poststroke management. Optimism and social support are known to protect against depressive symptoms. However, little is known about how optimism and social support contribute to depressive symptoms among stroke survivor-caregiver dyads. The study's purpose was to examine actor and partner effects of optimism on depressive symptoms through perceived social support among stroke survivors and caregiver dyads in the chronic stage of rehabilitation. METHODS: Stroke survivors and caregivers (N = 105 dyads) completed the survey at 2 years of follow-up after the first stroke. Depressive symptoms, optimism, and perceived social support were assessed using the Center for Epidemiologic Studies-Depression, the Life Orientation Test, and the Interpersonal Support Evaluation List. The Actor-Partner Interdependence Model Extended to Mediation analysis was used to test the indirect effect of optimism on depressive symptoms through perceived social support. RESULTS: Higher optimism was significantly associated with lower depressive symptoms for caregivers (direct actor effect, -0.6844; 95% confidence interval [CI], -0.9844 to -0.3844) and stroke survivors (direct partner effect, -0.4189; 95% CI, -0.0789 to -0.0889). Perceived social support availability significantly mediated the association between optimism and depressive symptoms for stroke survivors (indirect effect, -0.1957; 95% CI, -0.3923 to -0.0670). Caregiver perceived social support availability was also a significant mediator between caregivers' optimism and stroke survivors' depressive symptoms (indirect effect, 0.1658; 95% CI, 0.0559-0.3128). CONCLUSIONS: Intervention improving dyad members' optimism and social support would be beneficial to improve depressive symptoms of the stroke survivors and caregivers in chronic stroke management.
ABSTRACT
BACKGROUND: High levels of perceived control and lower levels of depressive symptoms are associated with better well-being in both patients with heart failure and their spouses at an individual level. However, there is a knowledge gap about how these individual factors have reciprocal influences on partners' well-being within the patient-spouse dyads. OBJECTIVE: The aims of this study were to examine dyads of patients with heart failure and their spouses on whether the patients' perceived control over the management of heart failure and depressive symptoms predicts their own and their spouses' physical and emotional well-being and to examine whether patients' perceived control predicts their own and their spouses' depressive symptoms. METHODS: A total 155 patient-spouse dyads (patients: 75% male, mean age of 71 years, 53% classified as New York Heart Association III; spouses: 75% female, mean age of 69 years) were recruited from 2 hospital-based outpatient heart failure clinics. Participants completed the Control Attitude Scale, the Beck Depression Inventory, and the Short-Form 36. Dyadic data were analyzed using multilevel regression of the actor-partner interdependence model. RESULTS: Perceived control had an actor effect on emotional well-being only for patients, and there were partner effects of perceived control on emotional well-being for both patients and their spouses. Depressive symptoms exhibited an actor effect on physical and emotional well-being for patients and spouses, but there were no partner effects of depressive symptoms on emotional well-being. Perceived control had partner effects on depressive symptoms for patients and spouses, but an actor effect of depressive symptoms was only found for patients. CONCLUSION: In an interdependent relationship within the patient-spouse dyads, each dyad member's perceived control influenced their partner's emotional well-being as well as depressive symptoms. The findings suggest development of dyadic interventions that can increase perceived control over the heart condition.

BACKGROUND: Adherence to a low-sodium diet is essential to self-care of heart failure (HF). Genetic determinants of preference for high-sodium foods may impede adherence but have not been well-studied. OBJECTIVE: Our purpose was to examine if TAS2R38 haplotype predicted salt taste sensitivity and dietary sodium intake among patients with HF. METHOD: This pilot study used baseline data from a large interventional randomized control trial to support adherence to a low-sodium diet in patients with HF and their family caregivers. Participants were tested for salt taste sensitivity and provided a 24-hour urinary sodium sample and a blood sample for DNA analysis at baseline. Fungiform papillae were counted. χ2 Test and 1-way analysis of variance were used to compare haplotype groups. Linear regression was performed to examine predictors of salt taste sensitivity and 24-hour urinary sodium excretion, controlling for age, gender, ethnicity, smoking status, and fungiform papillae density. RESULTS: There were 42 patients with HF and their family caregivers (age, 64.6 ± 13.4 years, 46.5% male, 97.7% white, and 90.7% nonsmoker). Pronine-alanine-valine homozygous haplotype predicted lower urinary sodium excretion (b = -1780.59, t41 = -2.18, P = .036), but genotype was not a significant predictor of salt taste sensitivity. CONCLUSIONS: The results of our study partially supported our hypothesis that PAV homozygous haplotype predicts 24-hour urinary sodium excretion. With our small sample size, more research is needed. Understanding genetic influences on taste can lead to development of educational interventions tailored to patients with HF and their family caregivers to better support dietary adherence.

BACKGROUND: The purpose of this study was to identify patterns of depressive symptom trajectory and examine the associations of the symptom trajectory with caregiving burden, family function, social support, and perceived health status of caregivers of stroke survivors during the first year of caregiving after discharge from rehabilitation center. METHODS: Caregivers of stroke survivors completed a survey of depressive symptoms, caregiving burden, family function, perceived availability of social support, and perceived health status at postdischarge and 1 year. Patterns of depressive symptom trajectory (ie, symptom-free, symptom relieved, symptom developed, and persistent symptom groups) were identified by grouping depressive symptoms based on 2 assessments using the Center for Epidemiologic Studies-Depression. Repeated-measures analysis of variance and multinomial logistic regression were used to examine the associations. RESULTS: Of the 102 caregivers, 57.8% were symptom-free, 20.6% experienced persistent depressive symptoms, 11.8% relieved depressive symptoms, and 9.8% developed depressive symptoms. There were significant changes in family function (Wilks λ = 0.914, P = .038) and perceived health status (Wilks λ = 0.914, P = .033) among the groups during the first year of caregiving. The persistent symptom group reported the highest level of burden and the lowest level of family function and perceived availability of social support at both assessment times. Compared with symptom-free caregivers, caregivers with persistent depressive symptoms were 7 times more likely to have fair/poor health rather than excellent/very good health at 1 year (odds ratio, 7.149; P = .012). CONCLUSION: Caregivers with persistent depressive symptoms are the most vulnerable to negative psychosocial outcomes and poor perceived health status during the first year of caregiving from discharge for stroke survivors.

Purpose The purpose of this study was to explore how adaptive patterns of religiousness/spirituality and hope predict adult life satisfaction in adults, even if they had childhood loss experiences.Design and Methods Using a cross-sectional survey design with132 adult participants (mean age 33.8 ± 15.2, 82% female, 78% Caucasian) we estimated two hierarchical regression models to examine how dimensions of religiousness/spirituality (Brief Multidimensional Measure of Religiousness/Spirituality) and hope (Herth Hope Index) predicted adult life satisfaction (Satisfaction with Life Scale) after controlling for effects of adverse childhood experiences (Adverse Childhood Experiences Study Questionnaire) or chronic sorrow from childhood loss (Kendall Chronic Sorrow Instrument).Results When effects of adverse childhood experiences (ACE) were controlled, higher levels of hope (ß = .416, p < .001) and forgiveness (ß = .273, p = .023) and lower levels of religious/spiritual values/beliefs (ß = -.298, p = .014) predicted higher levels of adult life satisfaction. ACE remained a significant predictor of adult life satisfaction in the final model. When controlling for effects of chronic sorrow, higher life satisfaction was predicted only by forgiveness (ß = .379, p = .003), values/beliefs (ß = -.354, p = .007), and hope (ß = .357, p < .001), with chronic sorrow not a significant predictor of adult life satisfaction in the final model.Conclusion: Greater life satisfaction for adult survivors of childhood loss experiences could be promoted by interventions to enhance hope and foster forgiveness. These adult survivors may also need support as they engage with religious/spiritual struggle to reconcile their values and beliefs with childhood loss.

BACKGROUND: Patients' negative illness perceptions and beliefs about cardiac rehabilitation (CR) can influence uptake and adherence to CR. Little is known about the interpartner influence of these antecedent variables on quality of life of patients with coronary artery disease (CAD) and their family caregivers. The aims of the study were: 1) to assess differences in illness perceptions, beliefs about CR and quality of life between patients with CAD and their family caregivers upon entry to a CR programme and at 6 months follow-up; and 2) to examine whether patients' and caregivers' perceptions of the patient's illness and beliefs about CR at baseline predict their own and their partner's quality of life at 6 months. METHODS: In this longitudinal study of 40 patient-caregiver dyads from one CR service, patients completed the Brief Illness Perception Questionnaire and Beliefs about Cardiac Rehabilitation Questionnaire at baseline and 6 months; and caregivers completed these questionnaires based on their views about the patient's illness and CR. The Short-Form 12 Health Survey was used to assess patients' and caregivers' perceived health status. Dyadic data were analysed using the Actor-Partner Interdependence Model. RESULTS: Most patients (70%) were men, mean age 62.45 years; and most caregivers (70%) were women, mean age 59.55 years. Caregivers were more concerned about the patient's illness than the patients themselves; although they had similar scores for beliefs about CR. Patients had poorer physical health than caregivers, but their level of mental health was similar. Caregivers' poorer mental health at 6 months was predicted by the patient's perceptions of timeline and illness concern (i.e. partner effects). Patient's and caregiver's illness perceptions and beliefs about CR were associated with their own physical and mental health at 6 months (i.e. actor effects). CONCLUSIONS: Overall, the patients and caregivers had similar scores for illness perceptions and beliefs about CR. The actor and partner effect results indicate a need to focus on specific illness perceptions and beliefs about CR, targeting both the individual and the dyad, early in the rehabilitation process to help improve patients and caregivers physical and mental health (outcomes).

BACKGROUND: Men with heart failure are reported to be less adherent to low-sodium diets than women are. One potential reason may be that men consume more food and, consequently, more sodium than women do. OBJECTIVES: The aims of this study were to compare dietary sodium intake, urine sodium excretion, and sodium density of diet consumed between men and women with heart failure and to determine whether sex moderated the relationship of kilocalories (kcals) consumed with dietary and urine sodium. METHODS: A total of 223 patients with heart failure (mean age, 62 ± 12 years; 70% men, 46% New York Heart Association class III-IV) completed detailed 4-day food diaries and provided 24-hour urine sodium samples. To account for sodium density of food, dietary sodium and urine sodium were referenced to sodium per 1000 kcal. RESULTS: On an absolute basis, men consumed 23% more kcals and 28% more sodium than women did; 24-hour sodium excretion was 16% higher in men than in women. There were no differences between men and women when dietary sodium and urinary sodium were referenced to 1000 kcal, indicating they consumed foods with similar sodium density. However, both moderation analyses showed that the dietary sodium intake of men and women with lower kcal intake was similar, whereas men with higher kcal intake consumed more sodium-dense foods than women did. CONCLUSION: The results suggest that the men with higher sodium intake than women had 2 reasons for nonadherence. They consumed more food and foods with higher sodium density than women did.

BACKGROUND: To improve the health outcomes of survivors of stroke, it is critical that they are highly motivated to engage in rehabilitation activities. Despite the increasing prevalence of strokes among middle-aged adults, there is limited knowledge regarding factors that may affect survivors' motivation to engage in rehabilitation. OBJECTIVE: The aim of this study was to examine the relationship among factors that predict the rehabilitation motivation of middle-aged survivors after a stroke through structural equation modeling. METHODS: A total of 200 middle-aged (40-64 years) survivors of stroke from 9 rehabilitation hospitals in Korea completed questionnaires on depressive symptoms, self-efficacy, social support, and rehabilitation motivation. Information on clinical characteristics, including physical function (activities performed during daily life), was collected through the review of medical records. Structural equation modeling was used to construct a prediction model of rehabilitation motivation. RESULTS: The average subject's age was 56.2 ± 6.6 years, and the mean time since the event of their stroke was 15.02 ± 8.95 months. Subjects' self-efficacy (being able to live everyday life) after their stroke (ß = .500, P < .001) and the social support provided by family and medical personnel (ß = .284, P < .010) directly affected their rehabilitation motivation. The bootstrapping method showed that depressive symptoms indirectly affected rehabilitation motivation through self-efficacy, as did physical function. CONCLUSIONS: In middle-aged survivors of stroke, self-efficacy and social support play a critical role in maintaining intrinsic motivation to engage in rehabilitation activities. Self-efficacy should be evaluated periodically and improved by encouraging individuals to achieve goals, emphasizing their self-regulation, especially among those who reported depressive symptoms and low physical function.

BACKGROUND: Patients with heart failure (HF) and their family caregivers usually consume similar diets, but there is a lack of evidence about diet quality of patients with HF and their family caregivers. OBJECTIVE: The specific aim of this study was to compare diet quality of patients with HF with that of their family caregivers. METHODS: In this cross-sectional study, 40 patients with HF and their 40 family caregivers completed a VioScreen Food Frequency Questionnaire from which Healthy Eating Index-2010 (HEI) diet quality scores (consisting of the total HEI score and 12 component scores) were calculated. RESULTS: None of the 40 patient-caregiver dyads had a high diet quality score (ie, total HEI > 80), whereas 21% of participants had poor diet scores (ie, total HEI ≤ 50). There were no differences in total HEI scores (58.5 vs 59.4, P = .58) or the 12 component scores of the HEI within dyad members. Mean scores of 6 of the 12 components (ie, total fruit, greens and beans, total protein foods, seafood and plant proteins, fatty acids, empty calories) for both members of the HF dyad were lower than the national average. Interestingly, scores for the sodium component were similarly low in patients and caregivers (4.1 vs 3.4, P = .24), indicating high sodium intake. CONCLUSION: Both patients and caregivers consume poor-quality diets that are high in sodium. These findings suggest that nutrition interventions to improve diet quality for patients with HF need to be targeted at the family as a unit.

BACKGROUND: Cardiovascular disease (CVD) and risk factors for CVD are prevalent among Appalachians from Kentucky. Appalachian men and women have high rates of engagement in unhealthy behaviors and poor physical health measures that increase their risk for CVD. OBJECTIVE: In this study, the relationship among gender, CVD risk factors, and health perception in Appalachians from Kentucky was explored. METHODS: This cross-sectional secondary analysis is from a randomized controlled trial on CVD health in rural Kentucky. To assess gender differences in smoking history, χ was used. Independent t tests compared the mean between participants 50 years or younger and those older than 50 years with differences in body mass index (BMI), waist circumference, systolic and diastolic blood pressure, hemoglobin A1C, total cholesterol, and physical activity. A multivariate linear regression analysis assessed variables predicting the outcome of health perception. RESULTS: Most participants had a mean BMI of 33 kg/m and 94.3% of men used smokeless tobacco compared to 5.7% of the women. Differences existed between gender and current, ever, or never smoked (P < .001). Women had higher total cholesterol levels but men had higher waist circumference. Participants older than 50 years had higher engagement in physical activity than did those 50 years or younger. Higher BMI and hemoglobin A1C level were significant predictors of worse health perception (P ≤ .05). For every unit increase in the physical activity scale, there was a 0.2-unit improvement in health perception (P ≤ .001). CONCLUSION: Appalachians from Kentucky have many CVD risk factors. Minimal engagement in preventative measures against CVD can worsen patient outcomes.

BACKGROUND: Self-efficacy is a critical factor for quality of life in patients who undergo coronary artery bypass grafting, as well as for their family caregivers. However, there is lack of knowledge about whether patients' self-efficacy and caregivers' perceptions of patient self-efficacy are associated with quality of life in patient and caregiver dyads. OBJECTIVES: The aims of this study were to compare self-efficacy and quality of life between patients and family caregivers and to examine whether patients' and caregivers' perceptions of patient self-efficacy were associated with their own and their partner's quality of life in patient and caregiver dyads who were waiting for patients' coronary artery bypass grafting. METHODS: In this cross-sectional study, 84 dyads (85% male patients and 87% female caregivers) completed the Cardiac Self-efficacy Scale, which consists of self-efficacy for controlling symptoms and self-efficacy for maintaining function subscales, and the Short-Form 12 Health Survey for quality of life. Data were analyzed using the Actor-Partner Interdependence Model. RESULTS: Caregivers rated patient self-efficacy for maintaining function higher than did patients themselves and caregivers' perceptions were positively correlated with patients' physical health. Patients' self-efficacy for maintaining function exhibited an actor effect on their own mental health. There were no other actor or partner effects of self-efficacy on quality of life. CONCLUSIONS: Differences between patients' and caregivers' perceptions of patient self-efficacy for maintaining function should be addressed before surgery to reduce discordance. Patients' self-efficacy for maintaining function was associated with their own quality of life. There was no partner (relationship) effect of self-efficacy on quality of life. More research is needed in this area.

BACKGROUND: Low-sodium diet adherence is foundational to heart failure (HF) self-management. Altered salt taste perception caused by angiotensin-converting enzyme (ACE) inhibitors commonly prescribed to patients with HF may increase sodium consumption. We hypothesized sodium intake, indicated by dietary sodium density, would be significantly higher among patients with HF prescribed ACE inhibitors compared with those not prescribed the drug. OBJECTIVE: The aim of this study was to assess the association between prescribed ACE inhibitors and dietary sodium density in patients with HF. METHODS: We conducted a secondary analysis of baseline data from patients with HF in an observational longitudinal study. Sodium density was derived by dividing averaged daily sodium intake from 4-day food diaries by averaged kilocalories consumed. Medical chart review was conducted to ascertain prescribed medications. Patients were categorized as prescribed and not prescribed an ACE inhibitor. t Tests were conducted to compare sodium intake between groups, and linear regression was conducted to examine whether prescribed ACE inhibitors independently predicted sodium density controlling for age, gender, New York Heart Association class, prescribed diuretics, and ß-blockers. RESULTS: Analyses included 255 patients with HF aged 61 ± 12 years, with 67% male, 44% New York Heart Association class III/IV, and 68% prescribed an ACE inhibitor. Compared with those not prescribed an ACE inhibitor, 13% more sodium per kilocalorie was consumed by patients prescribed an ACE inhibitor. Prescribed ACE inhibitor independently predicted dietary sodium density (ß = 0.238, P = .009). CONCLUSIONS: Sodium intake was higher among patients prescribed ACE inhibitors. Interventions to assist patients with HF with dietary sodium adherence can be informed by assessing medication regimens.

BACKGROUND: Heart failure (HF) patient-caregiver dyads experience severe psychological problems, such as anxiety and depression. A variable that has been found to be associated with anxiety and depression in patients and caregivers in severe chronic conditions is mutuality. However, this association has not been explored in HF patient-caregiver dyads to date. OBJECTIVE: The aim of this study was to evaluate the associations among mutuality, anxiety, and depression in HF patient-caregiver dyads. METHODS: This was a cross-sectional study. Mutuality, anxiety, and depression in HF patient-caregiver dyads were assessed using the Mutuality Scale (MS) total and 4 dimension scores and the Hospital Anxiety and Depression Scale, respectively. Data were analyzed using the actor-partner interdependence model to examine how mutuality of patients and caregivers was associated with both the patients' own (actor effect) and their partners' anxiety and depression (partner effect). RESULTS: A sample of 366 dyads of patients with HF (mean age, 72 years; 56% male) and caregivers (mean age, 54 years; 73.3% female) was enrolled. Regarding patient anxiety, we observed only an actor effect between the MS dimension scores of "love and affection" and "reciprocity" and anxiety in patients (B = -1.108, P = .004 and B = -0.826, P = .029, respectively). No actor and partner effects were observed concerning caregiver anxiety. Regarding depression, we observed that only the MS dimension of "love and affection" in patients had both an actor (patient: B = -0.717, P = .032) and a partner (caregiver: B = 0.710, P = .040) effect on depression. CONCLUSIONS: The assessment of MS in HF patient-caregiver dyads is important to formulate interventions aimed at improving anxiety and depression in patients and caregivers.
