The Moderating Role of Collectivism on Physical Activity and Family Support: A Cross-Sectional Design.

BACKGROUND: An important value among Korean Americans is collectivism or giving a group priority over the individual. This value, family support, and demographic characteristics have been reported to influence health behaviors among this group. Yet, no study has examined how collectivism, family support, and demographic characteristics interact with each other and then influence physical activity among Korean American adults. The purpose of the study was to examine the association between family support and physical activity, and the moderating role of demographic characteristics and collectivism on this association among Korean American adults. METHODS: A descriptive, cross-sectional study was conducted with a sample of 110 Korean American adults 18 years and older, residing in a Southwestern city in the United States. Self-administered questionnaires were used to measure demographics, collectivism, family support, and physical activity. RESULTS: Data analysis using a zero-inflated negative binomial regression model revealed a positive relationship between family support and physical activity, while age and gender were moderators of the relationship between family support and physical activity. Collectivism was positively related to physical activity and moderated the relationship between family support and physical activity. CONCLUSION: These findings indicate the significance of collectivism and family support that influence Korean American adults' physical activity.

Feasibility Study of the Health Empowerment Intervention in Older Adults With Heart Failure.

BACKGROUND: Of almost 5.7 million Americans with heart failure, 80% are 65 years and older. Empowerment approaches facilitating recognition of personal and social contextual resources may improve well-being in this vulnerable population. OBJECTIVE: This research evaluated the feasibility of the Health Empowerment Intervention (HEI) in older adults with heart failure, including effects on health empowerment, purposeful participation, self-management, functional health, and well-being. METHODS: Twenty older adults with heart failure were randomly assigned to HEI or Attention Control conditions. The HEI consisted of 6 weekly sessions based on the Health Empowerment Theory. Outcomes were measured at baseline and at 6 weeks. RESULTS: Feasibility of the HEI was supported; participants realized significant improvement in health empowerment and purposeful participation in goal attainment.ConclusionsThis research supports the feasibility of the HEI and provides a basis for continued evaluation.

Body Composition Outcomes of Tai Chi and Qigong Practice: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

PURPOSE: Meditative movement (MM) practices are increasingly being studied, including examination of the potential for these modalities to contribute to weight management. METHODS: A search was conducted for randomized controlled trials testing one or both of two forms of MM, Tai Chi and Qigong, reporting effects on changes in body composition. Data from these studies were extracted and tabled, and a meta-analysis of studies with inactive control conditions was conducted. Risk of bias was assessed, and seven RCTs had a low risk of bias. Sources of bias include publication bias and selection of English only. RESULTS: Publications meeting inclusion criteria yielded 24 studies (N = 1621 participants). Significant improvements in body composition, primarily body mass index, were noted for 41.7% of studies. A synthesis table describes the distribution of design factors, including type of comparison condition (inactive vs. active) and baseline body composition status (whether or not overweight/obese). A meta-analysis was conducted on 12 studies with inactive controls (using a random effects model) finding a small-to-medium treatment effect (SMD = - 0.388, CI = [- 0.732, - 0.044], t = 2.48, p < 0.03) for TC or QG interventions with a high level of heterogeneity. CONCLUSIONS: Tai Chi and Qigong show demonstrable effects on body composition, when compared to inactive control conditions. Systematic evaluation and valid conclusions regarding the impact of Tai Chi and Qigong on body composition outcomes will require more targeted study designs and control of comparison conditions.

Physical activity, benefits, and barriers across the aging continuum.

BACKGROUND: A growing body of evidence indicates the importance of physical activity during midlife period linked to the likelihood of healthy aging, while the likelihood of an individual engaging in physical activity depends largely on their perceived benefits and barriers to being physically active. AIM: This study was to examine physical activity levels of midlife Korean American adults and their perceived benefits and barriers to physical activity compared with young and older adults. METHODS: We conducted a secondary analysis of data collected for a larger descriptive, cross-sectional study that was conducted with a sample of 517 Korean American adults in a Midwestern city. Data were collected using a survey questionnaire. RESULTS: A little more than half of the sample were women (57.1%), with a mean age of 41.6 (±â€¯13.4). The study sample met the current guidelines for physical activity far less than the general U.S. population (30.4% -34.6 vs. 51.7%). Less midlife adults met the guidelines for moderate-intensity physical activity than older adults (34.2% vs. 57.4%), while less midlife adults met the guidelines for vigorous-intensity physical activity than young adults (24.8% vs. 40.6%). Midlife adults perceived fewer benefits than did young and older adults. CONCLUSION: The findings indicate that midlife adults are less likely to engage in physical activity and probably more at risk for unhealthy ageing than young and older adults. Understanding benefits and barriers of target population is the first step in developing culturally and age-appropriate intervention to promote physical activity.

Linking childhood abuse and hypertension: sleep disturbance and inflammation as mediators.

The indirect association of childhood abuse with prevalent hypertension in adulthood through sleep disturbance and pro-inflammatory biomarkers was investigated in 589 community-dwelling, middle-aged adults. Participants completed the Childhood Trauma Questionnaire and self-reported current sleep disturbance and medical diagnoses including hypertension. Blood pressure was taken and blood samples were analyzed for C-reactive protein, interleukin-6, and fibrinogen. Hypertension was present in 41.3 % of the sample. In the full multiple mediation model, tested using structural equation modeling, all hypothesized pathways were significant (p's < 0.05). Childhood abuse was significantly related to both body mass index and sleep disturbance, which, both in turn, were significantly associated with inflammation, which was subsequently associated with hypertension status. The model demonstrated good fit [χ(2) (122) = 352.0, p < 0.001, CFI = 0.918, RMSEA = 0.057] and the indirect effect of all mediators was significant (indirect effect: 0.02, 95 % CI 0.005-0.03, p = 0.001). Sleep disturbance, body mass, and inflammation may be independent, intermediate steps between childhood abuse and subsequent hypertension that may be amenable to biobehavioral interventions.

Comparison and evaluation of dietary quality between older and younger Mexican-American women.

OBJECTIVE: To compare and evaluate the dietary quality of young and older sedentary Mexican-American women. Understanding key dietary concerns, while considering developmental transition periods and cultural relevance, can provide insight for developing appropriate nutrition interventions. DESIGN: Cross-sectional dietary data were collected using unannounced 24 h diet recalls to assess nutrient intake adequacy (Estimated Average Requirement cut-point method) and dietary quality (Healthy Eating Index (HEI) 2010). SETTING: Mujeres en Acción and Madres para la Salud, two community-based physical activity interventions. SUBJECTS: Participants were 139 young (28 (sd 6) years) and 124 older (55 (sd 7) years) overweight/obese sedentary Mexican-American women (BMI=25·0-35·0 kg/m2) of low socio-economic status. RESULTS: Older women consumed less Ca, Fe, folate, empty calories and energy from carbohydrate, but more fruit, vegetables, greens and beans, and fibre than younger women (all P<0·05). Over 60 % of all participants had an intake below recommendations for fibre, Ca, vitamin E, vitamin C and folate. Both groups had low total HEI-2010 scores (62 for older and 63 for younger women; NS), with 57 % of older and 48 % of younger women classified as having a poor diet. CONCLUSIONS: Despite differences in nutrient requirements according to developmental transition periods (childbearing v. perimenopausal), overall, older and younger Mexican-American women generally had low-quality diets and may benefit from dietary quality improvement.

Evaluating the Validity of an Automated Device for Asthma Monitoring for Adolescents: Correlational Design.

BACKGROUND: Symptom monitoring is a cornerstone of asthma self-management. Conventional methods of symptom monitoring have fallen short in producing objective data and eliciting patients' consistent adherence, particularly in teen patients. We have recently developed an Automated Device for Asthma Monitoring (ADAM) using a consumer mobile device as a platform to facilitate continuous and objective symptom monitoring in adolescents in vivo. OBJECTIVE: The objectives of the study were to evaluate the validity of the device using spirometer data, fractional exhaled nitric oxide (FeNO), existing measures of asthma symptoms/control and health care utilization data, and to examine the sensitivity and specificity of the device in discriminating asthma cases from nonasthma cases. METHODS: A total of 84 teens (42 teens with a current asthma diagnosis; 42 without asthma) aged between 13 and 17 years participated in the study. All participants used ADAM for 7 consecutive days during which participants with asthma completed an asthma diary two times a day. ADAM recorded the frequency of coughing for 24 hours throughout the 7-day trial. Pearson correlation and multiple regression were used to examine the relationships between ADAM data and asthma control, quality of life, and health care utilization at the time of the 7-day trial and 3 months later. A receiver operating characteristic (ROC) curve analysis was conducted to examine sensitivity and specificity based on the area under the curve (AUC) as an indicator of the device's capacity to discriminate between asthma versus nonasthma cases. RESULTS: ADAM data (cough counts) were negatively associated with forced expiratory volume in first second of expiration (FEV1) (r=-.26, P=.05), forced vital capacity (FVC) (r=-.31, P=.02), and overall asthma control (r=-.41, P=.009) and positively associated with daily activity limitation (r=.46, P=.01), nighttime (r=.40, P=.02) and daytime symptoms (r=.38, P=.02), and health care utilization (r=.61, P<.001). Device data were also a significant predictor of asthma control (ß=-.48, P=.003), quality of life (ß=-.55, P=.001), and health care utilization (ß=.74, P=.004) after 3 months. The ROC curve analysis for the presence of asthma diagnosis had an AUC of 0.71 (95% CI 0.58-0.84), which was significantly different from chance (χ(2) 1=9.7, P=.002), indicating the device's discriminating capacity. The optimal cutoff value of the device was 0.56 with a sensitivity of 51.3% and a specificity of 72.7%. CONCLUSIONS: This study demonstrates validity of ADAM as a symptom-monitoring device in teens with asthma. ADAM data reflect the current status of asthma control and predict asthma morbidity and quality of life for the near future. A monitoring device such as ADAM can increase patients' awareness of the patterns of cough for early detection of worsening asthma and has the potential for preventing serious and costly future consequences of asthma.

Correlates of depressive symptoms after birth for Latinas who are overweight or obese.

Depression symptoms and overweight/obesity are common concerns during childbearing. Both conditions are associated with poor outcomes at birth and can have long-lasting consequences. Predictors of depressive symptoms among overweight and obese low-income and ethnically diverse women are not known. Data are from the Madres para la Salud trial with 139 postpartum Latinas. Depressive symptoms during a prior pregnancy were positively related, while social support and moderate intensity physical activity (PA) were negatively related to depressive symptoms after birth. Social support and PA may be effective interventions, particularly for women who have experienced depressive symptoms in a prior pregnancy.

A comparison of a social support physical activity intervention in weight management among post-partum Latinas.

BACKGROUND: Weight gain during the childbearing years and failure to lose pregnancy weight after birth contribute to the development of obesity in postpartum Latinas. METHODS: Madres para la Salud [Mothers for Health] was a 12-month, randomized controlled trial exploring a social support intervention with moderate-intensity physical activity (PA) seeking to effect changes in body fat, fat tissue inflammation, and depression symptoms in sedentary postpartum Latinas. This report describes the efficacy of the Madres intervention. RESULTS: The results show that while social support increased during the active intervention delivery, it declined to pre-intervention levels by the end of the intervention. There were significant achievements in aerobic and total steps across the 12 months of the intervention, and declines in body adiposity assessed with bioelectric impedance. CONCLUSIONS: Social support from family and friends mediated increases in aerobic PA resulting in decrease in percent body fat. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01908959.

Worry Among Mexican American Caregivers of Community-Dwelling Elders.

This mixed methods, multi-site, National Institute of Nursing Research (NINR)-funded, interdisciplinary, descriptive study aimed to identify expressions of worry in qualitative data obtained from caregiving Mexican American (MA) families assisting older adults. The purpose of this portion of the inquiry was to determine how worry is expressed, what happens to caregivers when they worry, and what adaptive strategies they used. We examined semi-structured interviews completed during six in-home visits with 116 caregivers. We identified 366 worry quotations from 639 primary documents in ATLAS.ti, entered them into matrices, and organized findings under thematic statements. Caregivers expressed cultural and contextual worries, worried about transitions and turning points in care, and identified adaptive strategies. Despite these strategies, worry persisted. Constant worry may be an allied, important aspect of caregiver burden. We need additional longitudinal research to better understand the experience of MA caregivers for older adults and to provide empirically supported interventions, programs, and services that reduce worry.

Effects of a physical activity and healthy eating intervention to reduce stroke risk factors in older adults.

OBJECTIVE: To evaluate the effects of a theory-based physical activity and healthy eating intervention aimed at reducing stroke risk factors among overweight/obese and sedentary older adults. METHODS: Between 12/2009-1/2011, participants (n=69) were randomly assigned to an 8-week group motivational intervention or biweekly newsletters by mail. Physical activity (blinded pedometer, 7-day recall) body composition, theoretical mediator, and dietary (24-hour recall) variables were measured at pre-test and post-test. The physical activity and dietary outcomes are reported. RESULTS: For outcome measures, the follow-up was 90% for the intervention group (n=29) and 91% for the control group (n=34) for this sample. Statistically significant differences in the 7-day physical activity self-report were noted at post-test in the intervention group. The dietary measures were not statistically significant at post-test; however, the intervention group increased the quantity of vegetable servings. CONCLUSION: Limited efficacy testing was supported for a combined physical activity-dietary intervention, framed by a wellness-motivation theory, and designed to reduce stroke risk factors in older adults who are sedentary and overweight/obese. Limitations were identified and recommendations for additional research provided.

Evaluation of a peer-led asthma self-management program and benefits of the program for adolescent peer leaders.

BACKGROUND: Asthma is the leading chronic condition in adolescents. Nonetheless, research efforts to address adolescent asthma morbidity by applying a developmentally appropriate self-management intervention have been limited. Recently a peer-led asthma self-management program has been developed and implemented for adolescents. The purpose of the study was to assess the acceptability of a peer-led asthma program for adolescents based on participant feedback and to examine the program's impact on asthma outcomes in peer leaders. METHODS: Adolescents with persistent asthma (n = 91, 13-17 years) participated in a camp-based asthma program led by peer leaders (the intervention group) or healthcare professionals (the control group), and completed a set of program evaluation forms. Peer leaders (n = 14, 16-20 years) completed study questionnaires measuring asthma knowledge, self-efficacy, asthma control, and quality of life at baseline, immediately after camp, and 3, 6, and 9 months post-camp. RESULTS: The peer-led group reported more positive experience with the program than the adult-led group (P = .01, Cohen's d = 0.53), particularly in its usefulness in dealing with asthma. Peer leaders were rated by participants highly on knowledge (98%), attitudes (93-96%), personal skills (91%), and perceived similarities (80-86%). Significant improvements were found in peer leaders' knowledge (P < .001, η(2) = 0.87), self-efficacy (P < .001, η(2) = 0.74), asthma control (P = .01, η(2) = 0.66), and quality of life in emotional functioning (P = .002, η(2) = 0.82) and activity (P = .003, η(2) = 0.62). CONCLUSIONS: A peer-led asthma self-management program was successfully implemented and well received by adolescent learners. Asthma outcomes in peer leaders appear to have improved as a result of the program, although caution should be exercised in determining clinical meaningfulness, given the modest changes in mean scores. ClinicalTrials.gov registration NCT01161225.

Predicting physical activity and fruit and vegetable intake in adolescents: a test of the information, motivation, behavioral skills model.

Most adolescents do not meet national recommendations regarding physical activity and/or the intake of fruits and vegetables. The purpose of this study was to explore whether variables in the information, motivation, behavioral skills (IMB) model of health promotion predicted physical activity and fruit and vegetable intake in 404 adolescents from 2 high schools in the Southwest United States using structural equation modeling (SEM). The SEM models included theoretical constructs, contextual variables, and moderators. The theoretical relationships in the IMB model were confirmed and were moderated by gender and race. Interventions that incorporate cognitive-behavioral skills building may be a key factor for promoting physical activity as well as fruit and vegetable intake in adolescents.

Activities of daily living in Mexican American caregivers: the key to continuing informal care.

La familia drives elder care in Mexican-American (MA) families, but nursing home placement can result from day-to-day caregiving demands that increase caregiver difficulty with activities of daily living (ADLs). Using life course perspective, this article describes the initial data wave of 31 MA caregivers from a descriptive, longitudinal, mixed-methods study of 110 MA caregivers and care recipients over 15 months in their caregiving trajectories. Fifteen of 31 caregivers consistently indicated "no help needed" on the Katz ADL, whereas all but one reported "help needed" during semistructured interviews with cultural brokers. In addition to the discrepancy between results on the Katz ADL and interviews, findings include consideration of nursing home placement by moderately acculturated caregivers and minimization of their illnesses by caregivers. Additional methods of MA caregiver assessment may be needed due to the questionable accuracy of the Katz ADL; additional research should explore minimization and acculturation in MA caregivers.

Mujeres en accion: design and baseline data.

The majority of programs designed to promote physical activity in older Hispanic women includes few innovative theory-based interventions that address cultural relevant strategies. The purpose of this report is to describe the design and baseline data for Mujeres en Accion, a physical activity intervention to increase regular physical activity, and cardiovascular health outcomes among older Hispanic women. Mujeres en Accion [Women in Action for Health], a 12 month randomized controlled trial to evaluate the effectiveness of a social support physical activity intervention in midlife and older Hispanic women. This study tests an innovative intervention, Mujeres en Accion, and includes the use of a theory-driven approach to intervention, explores social support as a theoretical mediating variable, use of a Promotora model and a Community Advisory group to incorporate cultural and social approaches and resources, and use of objective measures of physical activity in Hispanic women.

Mexican-American Males Providing Personal Care for their Mothers.

We know little about Mexican-American (MA) family adaptation to critical events in the informal caregiving experience but, in these days of economic and social turmoil, sons must sometimes step up to provide personal care for their aging mothers. This article compares two empirically real cases of MA males who provided such care, in lieu of a female relative. The cases are selected from a federally-funded, descriptive, longitudinal, mixed methods study of 110 MA caregivers and their care recipients. In case-oriented research, investigators can generate propositions (connected sets of statements) that reflect their findings and conclusions, and can be tested against subsequent cases: Caregiving strain and burden in MA males may have more to do with physical and emotional costs than financial ones; MA males providing personal care for their mothers adopt a matter-of-fact approach as they act "against taboo"; and this approach is a new way to fulfill family obligations.

Randomized control trial of the Health Empowerment Intervention: feasibility and impact.

BACKGROUND: Older adults prefer to stay in their homes for as long as possible but are often unaware of the resources in their community to help them to remain in their home. Access to resources may be important among older adults, representing a critical area for intervention. OBJECTIVES: The study aim was to evaluate the feasibility of the Health Empowerment Intervention (HEI) and to explore the impact of the HEI on the theoretical mediating variables of health empowerment and purposeful participation in goal attainment and the outcome variable of well-being with homebound older adults. METHOD: Fifty-nine eligible homebound older adults were randomly assigned to the intervention group or the comparison group. The HEI consisted of 6 weekly visits, whereas the comparison group received a weekly newsletter for 6 weeks. Participants were measured at baseline, after the 6-week protocol, and at 12 weeks. Data were analyzed using descriptive statistics, t test, chi, and analysis of covariance. RESULTS: There was a significant difference between groups in education. The participants in the intervention found the sessions to be helpful in recognizing resources. In addition, participants in the intervention group had significantly higher scores in the mediator purposeful participation in goal attainment, F(2, 83) = 3.71, p = .03. There was no significant main effect for the mediator health empowerment; however, the intervention group increased in the subscale personal growth from baseline to 12 weeks, F(1, 83) = 3.88, p = .05. DISCUSSION: This randomized control trial provided initial support for the hypothesis that homebound older adults receiving the HEI would find the intervention acceptable and have significantly improved health empowerment, purposeful participation in goal attainment, and well-being than an attentional comparison group receiving a weekly newsletter.

ReadySteady intervention to promote physical activity in older adults with Parkinson's disease: Study design and methods.

The main motor impairments of gait and balance experienced by people with Parkinson's disease (PD) contribute to a sedentary lifestyle, resulting in poor physical conditioning, loss of functional independence, and reduced quality of life. Despite the known benefits of physical activity in PD, the majority of older adults with PD are insufficiently active. Few studies incorporate behavioral change approaches to promoting physical activity in PD. The main goal of this research is to foster community mobility in older adults with PD by promoting physical activity and improving gait patterns using a theory-based behavioral change intervention. The ReadySteady intervention combines wellness motivation theory with polestriding physical activity, which has been shown to be beneficial for people with PD. The intervention will be tested using a randomized controlled design, including inactive older adults diagnosed with PD. Participants will be randomly assigned the 12-week ReadySteady intervention, 12-week polestriding, and education intervention, or 12-week education intervention. Thirty-six older adults with PD will participate in each of the interventions. Level of physical activity, clinical scores, quantitative measures of gait and balance control, and motivational variables for each intervention will be measured at three time points: pre-intervention, post-intervention (12 weeks), and follow-up (24 weeks). If the intervention is beneficial, it may serve as a sustainable addition to current practice in health promotion efforts serving the PD population.

Interventions for Cardiovascular Disease Risk Reduction in Korean Americans: A Systematic Review.

This systematic review was to identify and synthesize literature that described the cultural appropriateness and effectiveness of interventions aimed at cardiovascular risk reduction in Korean Americans. We searched multiple electronic databases for studies published between January 2000 and August 2017 and identified 14 eligible research reports. All reviewed studies targeted first-generation Korean American adults. Most of the reviewed studies incorporated components of surface structure, and leveraged deep structure in those interventions. Significant changes in cardiovascular health outcomes were reported in most of the reviewed studies; however, the role of cultural factors in the outcomes was rarely evaluated, and few reported long-term effects. Future research needs to consider long-term effects. Deploying cultural factors and evaluating their contributions to the target outcomes will enhance the research on cardiovascular health disparities.

Testing women's propensities to leave their abusive husbands using structural equation modeling.

BACKGROUND: Many Korean women are just beginning to recognize that what they considered to be normal treatment is actually domestic violence. Many are becoming more intolerant of the abuse and more likely to desire to leave an abusive relationship. OBJECTIVE: The aim of this study was to test, using the framework of sociostructural and psychological-relational power (PRP), a model of Korean women's propensities to leave their abusive husbands. METHODS: Multigroup structural equation modeling was used to test relationships between variables chosen from the sociostructural power and PRP to explain intolerance to abuse. Married Korean women (n = 184) who self-identified as being abused physically, psychologically, sexually, or financially participated in the study. RESULTS: The multigroup analysis revealed that the relationship of abuse and Hwa-Byung (a culture-bound syndrome that denotes Korean women's anger) with intolerance was supported for women with low education (defined as having an education of high school or less: < or =12 years); also for this group, particularly among the younger women, high power was related to high levels of reported abuse and abuse intolerance. For women in the high-education group (education beyond high school: > or =13 years), high power was related to abuse, Hwa-Byung, and abuse intolerance; age did not influence power. Overall, the multigroup model adequately fitted the sample data (chi2 = 92.057, degree of freedom = 50, p = .000; normal fit index = .926, comparative fix index = .964, root mean square error of approximation = .068, Hoelter's critical number = 152), demonstrating that education is a crucial moderator of Korean women's attitude toward the unacceptability of abuse and propensity to terminate the marriage. DISCUSSION: This study found support for a model of abuse intolerance using the framework of sociostructural power and PRP, primarily for the low-education group. Hwa-Byung was a mediating factor that contributed to intolerance to abuse in women with low education. This study highlights the importance of understanding the cultural assumptions that guide Korean women's beliefs and behaviors about abuse intolerance, suggesting that effective intervention programs should be specific to age and education, including a focus on resource availability, which could clarify the variations in Korean women's responses to abuse intolerance.
