RESUMEN

BACKGROUND: Diabetes-related multi-morbidity and cultural factors place Latinas with diabetes at increased risk for stress, which can threaten illness management. Families provide an ideal focus for interventions that seek to strengthen interpersonal resources for illness management and, in the process, to reduce stress. The current study sought to examine whether participating in a dyadic intervention was associated with reduced perceived stress and, furthermore, whether this association was mediated by persuasion and pressure, two forms of health-related social control. METHOD: Latina mothers with diabetes and their at-risk adult daughters participated in either (1) a dyadic intervention that encouraged constructive collaboration to improve health behaviors and reduce stress, or (2) a usual-care minimal control condition. Actor-partner interdependence model analysis was used to estimate the effect of the intervention on dyads' perceived stress, and mother-daughter ratings of health-related social control as potential mediators. RESULTS: Results revealed that participating in the intervention was associated with significantly reduced perceived stress for daughters, but not for mothers (ß = - 3.00, p = 0.02; ß = - 0.57, p = 0.67, respectively). Analyses also indicated that the association between the intervention and perceived stress was mediated by persuasion, such that mothers' who experienced more health-related persuasion exhibited significantly less post-intervention perceived stress (indirect effect = - 1.52, 95% CI = [- 3.12, - 0.39]). Pressure exerted by others, however, did not evidence a mediating mechanism for either mothers or daughters. CONCLUSION: These findings buttress existing research suggesting that persuasion, or others' attempts to increase participants' healthy behaviors in an uncritical way, may be a driving force in reducing perceived stress levels.

RESUMEN

BACKGROUND: Millions of traumatized refugees worldwide have resettled in the United States. For one of the largest, the Cambodian community, having their mental health needs met has been a continuing challenge. A multicomponent health information technology screening tool was designed to aid provider recognition and treatment of major depressive disorder and posttraumatic stress disorder (PTSD) in the primary care setting. METHODS: In a clustered randomized controlled trial, 18 primary care providers were randomized to receive access to a multicomponent health information technology mental health screening intervention, or to a minimal intervention control group; 390 Cambodian American patients empaneled to participating providers were assigned to the providers' randomized group. RESULTS: Electronic screening revealed that 65% of patients screened positive for depression and 34% screened positive for PTSD. Multilevel mixed effects logistic models, accounting for clustering structure, indicated that providers in the intervention were more likely to diagnose depression [odds ratio (OR), 6.5; 95% confidence interval (CI), 1.48-28.79; P=0.013] and PTSD (OR, 23.3; 95% CI, 2.99-151.62; P=0.002) among those diagnosed during screening, relative to the control group. Providers in the intervention were more likely to provide evidence-based guideline (OR, 4.02; 95% CI, 1.01-16.06; P=0.049) and trauma-informed (OR, 15.8; 95% CI, 3.47-71.6; P<0.001) care in unadjusted models, relative to the control group. Guideline care, but not trauma-informed care, was associated with decreased depression at 12 weeks in both study groups (P=0.003), and neither was associated with PTSD outcomes at 12 weeks. CONCLUSIONS: This innovative approach offers the potential for training primary care providers to diagnose and treat traumatized patients, the majority of whom seek mental health care in primary care (ClinicalTrials.gov number, NCT03191929).

RESUMEN

OBJECTIVES: Recently, there has been a call to better understand Latino health and arrive at effective approaches for achieving health equity via research focusing on the association between cultural factors and health. This study examined whether familism, a cultural value that emphasizes warm and close family relationships, would attenuate the negative effects that perceived stress, a psychological process that can worsen health, can have on two physical health indicators- number of health conditions and bodily pain. METHOD: Latina mothers (n = 85, Mage = 52.68, SD = 6.60) with Type 2 diabetes and their daughters (n = 86, Mage = 27.69, SD = 7.61) whose weight put them at risk for also developing the condition were recruited to take part in a larger intervention study aimed at improving weight loss/dietary intake. Participants completed measures of familism, perceived stress, health conditions, and bodily pain. RESULTS: Results indicated that in the daughters, familism and perceived stress interacted to predict health conditions and bodily pain. As familism decreased, stress was associated with more health conditions and more bodily pain. These interactions were not significant for the mothers. CONCLUSIONS: First, familism has the potential to buffer the negative effect of stress in ways that are protective for health among Latinas at risk for diabetes. Second, this buffering effect has boundary conditions, suggesting that a better understanding is needed of how, for whom, and under what circumstances familism can be beneficial for health.

RESUMEN

BACKGROUND: Despite declining cancer incidence and mortality rates, Latina patients continue to have lower 5-year survival rates compared to their non-Hispanic white counterparts. Much of this difference has been attributed to lack of healthcare access and poorer quality of care. Research, however, has not considered the unique healthcare experiences of Latina patients. METHODS: Latina women with prior diagnoses of stage 0-III breast cancer were asked to complete a cross-sectional survey assessing several socio-demographic factors along with their experiences as cancer patients. Using a series of linear regression models in a sample of 68 Mexican-American breast cancer survivors, we examined the extent to which patients' ratings of provider interpersonal quality of care were associated with patients' overall healthcare quality, and how these associations varied by acculturation status. RESULTS: Findings for Latina women indicated that both participatory decision-making (PDM) (ß = 0.62, p < .0001) and trust (ß = 0.53, p = .02) were significantly associated with patients' ratings of healthcare quality. The interaction between acculturation and PDM further suggested that participating in the decision-making process mattered more for less acculturated than for more acculturated patients (ß = -0.51, p ≤ .01). CONCLUSIONS: The variation across low and high acculturated Latinas in their decision-making process introduces a unique challenge to health care providers. Further understanding the relationship between provider-patient experiences and ratings of overall healthcare quality is critical for ultimately improving health outcomes.

RESUMEN

BACKGROUND AND OBJECTIVES: Cancer-related cognitive impairment has been acknowledged as a substantial limiting factor in quality of life among cancer patients and survivors. In addition to deficits on behavioral measures, abnormalities in neurologic structure and function have been reported. In this paper, we review findings from the literature on cognitive impairment and cancer, potential interventions, meditation and cognitive function, and meditation and cancer. In addition, we offer our hypotheses on how meditation practice may help to alleviate objective and subjective cognitive function, as well as the advantages of incorporating a meditation program into the treatment of cancer patients and survivors for cancer-related cognitive deficits. FINDINGS: Various factors have been hypothesized to play a role in cancer-related cognitive impairment including chemotherapy, reduced hormone levels, proinflammatory immune response, fatigue, and distress. Pharmacotherapies such as methylphenidate or modafinil have been suggested to alleviate cognitive deficits. While initial reports suggest they are effective, some pharmacotherapies have side effects and may not relieve other symptoms associated with multimodal cancer treatment including sleep disturbance, nausea and pain. Several recent studies investigating the effects of meditation programs have reported behavioral and corresponding neurophysiological modulations that may be particularly effective in alleviating cancer-related cognitive impairment. Such programs also have been shown to reduce stress, fatigue, nausea and pain, and improve mood and sleep quality. CONCLUSIONS: With the increasing success of cancer treatment and the ability to return to previous family, social, and work activities, symptom management and quality of life are an essential part of survivorship. We propose that meditation may help to improve cancer-related cognitive dysfunction, alleviate other cancer-related sequelae, and should be fully investigated as an adjuvant to cancer treatment.

RESUMEN

Asian Americans are understudied in health research and often aggregated into one homogenous group, thereby disguising disparities across subgroups. Cambodian Americans, one of the largest refugee communities in the United States, may be at high risk for adverse health outcomes. This study compares the health status and healthcare experiences of Cambodian American refugees and immigrants. Data were collected via questionnaires and medical records from two community clinics in Southern California (n = 308). Chi square and t-tests examined the socio-demographic differences between immigrants and refugees, and ANCOVA models compared the mean differences in responses for each outcome, adjusting for age at immigration, education level, and clinic site. Cambodian American refugees reported overall lower levels of health-related quality of life (all p's < 0.05 in unadjusted models) and self-rated health [unadjusted means (SD) = 18.2 (16.8) vs. 21.7 (13.7), p < 0.05], but either similar or more positive healthcare experiences than Cambodian American immigrants. In adjusted analyses, refugees had higher rates of diabetes and cardiovascular disease risk (e.g. heart condition and hypertension; p's < 0.05) compared to Cambodian American immigrants. There were minimal differences in self-reported health behaviors between the two groups. There is a need for more health promotion efforts among Cambodian American refugees and immigrants to improve their health outcomes and perceived wellbeing.

RESUMEN

BACKGROUND: Half of Mexican-American women are under-active and nearly 78% are overweight/obese. The high lifetime risk of developing type 2 diabetes necessitates a culturally appropriate lifestyle intervention. PURPOSE: Unidas por la Vida is a novel dyadic intervention that capitalizes on the centrality of family in Latino culture to mobilize an existing family dyad as a resource for health behavior change. The intervention aims to improve health behaviors and promote weight loss in two at-risk members of the same family: mothers with type 2 diabetes and their overweight/obese adult daughters who are at risk for developing diabetes. METHODS: Participants (N = 460 mother-adult daughter dyads) will be randomized into one of three conditions: 1) dyadic participation (mothers-daughters) in a lifestyle intervention; 2) individual participation (mothers alone; unrelated daughters alone) in a lifestyle intervention; and 3) mother-daughter dyads in a minimal intervention control group. RESULTS: The primary outcome is weight loss. Secondary outcomes include physical activity, dietary intake, physiological measures (e.g. HbA1c), and body composition. Both the dyadic and individual interventions are expected to produce greater weight loss at 6, 12, and 18 months than those in minimal intervention control group, with women assigned to the dyadic intervention expected to lose more weight and to maintain the weight loss longer than women assigned to the individual intervention. CONCLUSION: Because health risks are often shared by multiple members of at-risk families, culturally appropriate, dyadic interventions have the potential to increase the success of behavior change efforts and to extend their reach to multiple family members.

RESUMEN

OBJECTIVES: This study examined potential barriers to mental healthcare use of older adults from diverse ethnic and racial backgrounds. DESIGN: Data were obtained from the 2007, 2009, 2011-12, and 2013-14 California Health Interview Survey (CHIS), a population-based survey representative of California's noninstitutionalized population. PARTICIPANTS: The total sample consisted of 75,324 non-Hispanic white (NHW), 6,600 black, 7,695 Asian and Pacific Islander (API), and 4,319 Hispanic adults aged 55 and older. RESULTS: Results from logistic regression analyses that controlled for multiple demographic and health status characteristics revealed ethnic and racial differences in reasons for not seeking treatment and for terminating treatment. Specifically, API and Hispanic adults had greater odds than NHWs of endorsing feeling uncomfortable talking to a professional as a reason for not seeking treatment. Hispanic respondents had lower odds of endorsing concerns about someone finding out than APIs, and APIs and blacks had significantly greater odds of endorsing this concern as a reason for not seeking treatment than NHWs. When asked about reasons for no longer receiving treatment, all respondents, irrespective of race or ethnicity, endorsed that they no longer needed treatment as the most frequent reason for terminating treatment, although specific ethnic and racial differences emerged with respect to perceptions of not getting better, lack of time or transportation, and lack of insurance coverage as reasons for no longer seeking treatment. CONCLUSION: Understanding how barriers to mental health treatment differ for older adults from diverse ethnic and racial backgrounds is an important step toward designing interventions to overcome these obstacles and improve mental health outcomes.

RESUMEN

The prevalence rate of depression in primary care is high. Primary care providers serve as the initial point of contact for the majority of patients with depression, yet, approximately 50% of cases remain unrecognized. The under-diagnosis of depression may be further exacerbated in limited English-language proficient (LEP) populations. Language barriers may result in less discussion of patients' mental health needs and fewer referrals to mental health services, particularly given competing priorities of other medical conditions and providers' time pressures. Recent advances in Health Information Technology (HIT) may facilitate novel ways to screen for depression and other mental health disorders in LEP populations. The purpose of this paper is to describe the rationale and protocol of a clustered randomized controlled trial that will test the effectiveness of an HIT intervention that provides a multi-component approach to delivering culturally competent, mental health care in the primary care setting. The HIT intervention has four components: 1) web-based provider training, 2) multimedia electronic screening of depression and PTSD in the patients' primary language, 3) Computer generated risk assessment scores delivered directly to the provider, and 4) clinical decision support. The outcomes of the study include assessing the potential of the HIT intervention to improve screening rates, clinical detection, provider initiation of treatment, and patient outcomes for depression and post-traumatic stress disorder (PTSD) among LEP Cambodian refugees who experienced war atrocities and trauma during the Khmer Rouge. This technology has the potential to be adapted to any LEP population in order to facilitate mental health screening and treatment in the primary care setting.

RESUMEN

Older Hispanic Americans are a rapidly growing minority group who are disproportionately affected by diabetes mellitus and obesity. Given the importance of physical activity, particularly leisure-time activity, in the management of diabetes mellitus and obesity, the current study examined ethnic and sex differences in walking for transportation, leisure-time walking, moderate activity (not including walking), and vigorous activity between Hispanic and non-Hispanic white (NHW) older adults (age 55 and older) using the 2009 California Health Interview Survey, a population-based survey representative of California's noninstitutionalized population. The total sample consisted of 21,702 participants (20,148 NHW (7,968 men, 12,180 women) and 1,554 Hispanic (609 men, 945 women)). Multivariable logistic and linear regression analyses were adjusted for sociodemographic characteristics. The findings revealed that Hispanic men and women were significantly less likely to engage in self-reported leisure-time walking and vigorous activity than NHW men (adjusted odds ratio (aOR) = 0.71, 95% confidence interval (CI) = 0.51-0.99) and women (aOR = 0.60, 95% CI = 0.42-0.87). Regardless of ethnic group, men were more likely than women to engage in self-reported walking for transportation (aOR = 0.71, 95% CI = 0.58-0.87), moderate activity (aOR = 0.68, 95% CI = 0.57-0.81), and vigorous activity (aOR = 0.58, 95% CI = 0.50-0.68). All types of self-reported physical activity were associated with lower body mass index (BMI; P < .001), although significant interactions between sex and leisure time walking (P < .001), moderate activity (P < .001), and vigorous activity (P < .001) indicated that women who engaged in these activities reported the lowest BMIs. The findings highlight the importance of emphasizing walking in efforts to increase moderate and vigorous activity, particularly for older women.

RESUMEN

OBJECTIVE: This study sought to evaluate the feasibility of a pilot, dyad-based lifestyle intervention, the Unidas por la Vida program, for improving weight loss and dietary intake among high-risk Mexican American mothers who have Type 2 diabetes and their overweight/obese adult daughters. METHOD: Mother-daughter dyads (N = 89) were recruited from two federally qualified health centers and randomly assigned to either the Unidas intervention or to the control condition. The 16-week Unidas intervention consisted of the following: (a) four group meetings, (b) eight home visits, and (c) booster telephone calls by a lifestyle community coach. The control condition consisted of educational materials mailed to participants' homes. Participants completed surveys at T1 (baseline) and T2 (16 weeks) that assessed various demographic, social network involvement, and dietary variables. RESULTS: Unidas participants lost significantly more weight at T2 (p < .003) compared with the control participants. Furthermore, intervention participants also were more likely to be eating foods with lower glycemic load (p < .001) and less saturated fat (p = .004) at T2. Unidas participants also reported a significant increase in health-related social support and social control (persuasion control only) and a decrease in undermining. CONCLUSIONS: The Unidas program promoted weight loss and improved dietary intake, as well as changes in diet-related involvement of participants' social networks. The results from this study demonstrate that interventions that draw upon multiple people who share a health-risk have the potential to foster significant changes in lifestyle behaviors and in social network members' health-related involvement. Future research that builds on these findings is needed to elucidate the specific dyadic and social network processes that may drive health behavior change.

RESUMEN

Shortened telomere length is associated with increased cancer incidence and mortality. Populations experiencing chronic stress have accelerated telomere shortening. In this exploratory study, we examined associations between longitudinal changes in patient reported outcomes (PRO) of psychologic distress and peripheral blood mononuclear cell (PBMC) telomere length to test the hypothesis that modulation of the chronic stress response would also modulate telomere dynamics. Archived PBMC specimens (N = 22) were analyzed from a completed and reported randomized, longitudinal trial that showed a psychosocial telephone counseling intervention improved quality of life (QOL) and modulated stress-associated biomarkers in cervical cancer survivors. PROs and biospecimens were collected at baseline and 4 months postenrollment. Telomere length of archived PBMCs was evaluated using the flow-FISH assay. Longitudinal changes in psychologic distress, measured by the Brief Symptom Inventory-18, were significantly associated with increased telomere length within the CD14(+) (monocyte) population (r = -0.46, P = 0.043); a similar trend was observed for the CD14(-) population. Longitudinal changes in telomere length of the CD14(-) subset, primarily T lymphocytes, were associated with longitudinal increases in the naive T-cell population (r = 0.49, P = 0.052). Alterations in the chronic stress response were associated with modulation of telomere length in PBMCs, with evidence for mobilization of "younger" cells from progenitor populations. These data provide preliminary support for the (i) capacity to modulate the chronic stress response and the associated accelerated telomere shortening, (ii) inclusion of telomere length in the biobehavioral paradigm, and (iii) potential link between the chronic stress response and biologic mechanisms responsible for genomic integrity and carcinogenesis.

RESUMEN

The present study examined the associations between religion and spirituality (R/S), presurgical distress, and other psychosocial factors such as engagement coping, avoidant coping, and social support. Participants were 115 men scheduled for surgery for urologic cancer. Before surgery, participants completed scales measuring intrinsic religiosity, organized religious activity, and nonorganized religious activity (IR, ORA, NORA); social support (Medical Outcomes Study Social Support Survey); and distress (Impact of Event Scale [IES], Perceived Stress Scale [PSS], Brief Symptom Inventory-18 [BSI-18], and Profile of Mood States [POMS]). R/S was positively associated with engagement coping. Social support was positively associated with engagement coping and inversely associated with POMS and PSS scores. Engagement coping was positively associated with IES and BSI scores, and avoidant coping was positively associated with all distress measures. R/S moderated the association between engagement coping and IES scores, such that the association between engagement coping and IES was not significant for men with high R/S scores (greater religious belief). R/S moderated the association between social support and distress; the inverse association between social support and PSS and POMS scores was only significant for men who scored high on R/S. This study replicated findings from previous studies suggesting that engagement and avoidant types of coping can lead to increased distress prior to surgery. Although R/S was associated with engagement coping, it was not associated with any of the distress measures. The finding that R/S moderated the associations between engagement coping and distress and social support and distress suggests that the association between R/S, coping style, social support, and adjustment to stressful life situations is not simplistic, and indirect associations should be explored.

RESUMEN

We investigated the semantic blocking effect in picture naming and word-picture matching for two nonfluent aphasic patients who show evidence of a deficit in inhibiting verbal representations (M.L. and B.Q), one fluent aphasic patient (K.V.), and neurologically intact control participants. In two picture-naming tasks (Experiments 1A and 1B), M.L. and B.Q, relative to controls, showed a greatly exaggerated semantic blocking effect in naming latencies that increased dramatically across repeated presentations. On two corresponding word-picture matching tasks (Experiments 2A and 2B), both also showed an increasing semantic blocking effect, though the effects were not as large nor as consistent as those in naming. The fluent patient, K.V., showed a pattern like controls on both tasks. On an associated word-picture matching task, both M.L. and B.Q showed results paralleling those of controls. The contrast between the production and comprehension patterns for M.L. and B.Q. supports the conclusion that their exaggerated blocking effect in production arises during lexical rather than semantic selection. We postulate that M.L.'s (and potentially B.Q's) production effect is due to difficulties in postselection inhibition, which results in overactivation of lexical representations. This overactivation is likely to be one source of their nonfluency in spontaneous speech.

RESUMEN

Speech error data and empirical studies suggest that the scope of planning is larger for semantic than for phonological form representations in speech production. Previous results have demonstrated that some patients show dissociable impairments in the retention of semantic and phonological codes. The effect of these STM deficits on speech production was investigated using a phrase production paradigm that manipulated the semantic relatedness of the words in the phrase. Subjects produced a conjoined noun phrase to describe two pictures (e.g., "ball and hat") or produced the same phrases in response to pairs of written words. For the picture naming condition, control subjects showed an interference effect for semantically related pictures relative to unrelated pictures. This interference effect was greatly exaggerated for two patients with semantic short-term memory deficits but not for a patient with a phonological STM deficit. For the written words, control subjects showed a small facilitatory effect for the onset of phrases containing semantically related words. One of the patients with a semantic STM deficit who was tested on picture naming was also tested on these materials and showed a small facilitatory effect within the range of controls. The findings support the contention that speech planning is carried out at a phrasal level at the lexical-semantic level and that the capacities that support semantic retention in list recall support speech production planning.
