Evaluating the relationship between physical activity and quality of life in a racially diverse sample of breast cancer survivors.

PURPOSE: Physical activity (PA) has been shown to improve quality of life (QoL) in predominantly White cancer survivors. Very few studies have examined the association between PA and QoL among Black breast cancer survivors (BCS). We investigated the association between PA and multiple QoL domains and the effects of race on the proposed association in a racially diverse group of BCS. METHODS: This was an exploratory study using secondary data from a completed 12-month randomized controlled  trial (RCT). Mixed effects models were tested on a subset of participants in the control and exercise groups of the RCT. The primary outcomes were changes in the QoL domains (baseline to 12 months post baseline). RESULTS: There were 173 participants included in this analysis, averaging 59 years of age; about 33% of the participants were Black women. There were no significant differences in the QoL outcomes between the control and exercise groups at 12 months post baseline. Race was not a significant moderator. Exercise improved emotional/mental wellbeing and body image as it relates to social barriers at 12 months post baseline in Black and White BCS, but the changes in these outcomes were only statistically significant in White BCS (p < 0.05). CONCLUSIONS: Results show that exercise can improve multiple QoL domains over time in Black BCS. However, the significance of the effect on QoL was isolated to White BCS. The small sample size in Black women could constrain the statistical significance of observed effects. Future studies are warranted to assess associations between exercise and QoL in larger samples of Black women.

Exploring Quality of Life Experiences and Concerns of Black Breast Cancer Survivors: a Narrative Approach.

Black breast cancer survivors (BCS) in comparison with White BCS are more likely to experience suboptimal quality of life (QoL). QoL is a multi-dimensional concept that focuses on different aspects of well-being (e.g., emotional well-being). There is limited evidence on the perspectives and experiences of QoL (e.g., the influence of breast cancer on QoL) and the QoL concerns (e.g., negative perceptions of body appearance) among Black BCS. The purpose of this study was to explore the QoL experiences and QoL concerns of Black BCS. Primary data was collected in semi-structured interviews and analyzed using a thematic analysis. A narrative approach (detailed stories or life experiences of a small group of people) was used to better understand the research topic among the target group. Ferrell's Conceptual Framework on QoL in Breast Cancer was used to guide the development of the interview questions, codes, and themes. There were 10 Black BCS, averaging 58 years of age. Two coders achieved a moderate level of agreement (i.e., Kappa) of 0.77. Five major themes were identified: defining QoL (what QoL means to them), behavioral changes (e.g., altering behaviors due to cancer), phases of cancer (e.g., breast cancer diagnosis), QoL experiences and factors affecting QoL, and impactful statements from cancer survivors (other meaningful information shared by the participants). The survivors reported multiple QoL concerns and body image issues. The study findings warrant cancer education interventions or programs to address the relevant survivorship issues of Black BCS.

Race, Gender, and Socioeconomic Variations in C-Reactive Protein Using the Health and Retirement Study.

OBJECTIVES: To clarify the relationships among race, gender, and socioeconomic status (SES) with C-reactive protein (CRP). METHOD: The present study analyzed data from 6,521 Black and White respondents aged 51 and older in the Health and Retirement Study, a nationally representative sample of midlife and older adults, to address two aims. We sought to (i) assess the independent associations between race, gender, and SES with CRP concentrations and (ii) test whether race, gender, and SES interacted to produce unequal CRP concentrations cross-sectionally and over a 4-year follow-up. RESULTS: The results demonstrated that race, gender, and SES were each independently associated with baseline CRP, but only SES was associated with CRP at follow-up. Furthermore, race, gender, and education interacted to produce differential CRP levels at baseline. There were incremental benefits for each additional level of education for White men and women, but the relationship between education and CRP was more complicated for Black men and women. Compared with other race/gender groups with less than high school, Black women had the highest and Black men had the lowest levels of CRP. There were no apparent benefits to CRP for Black women with college compared with Black women with high school, while Black men with less than high school and college had similar concentrations of CRP. DISCUSSION: In clarifying the complexity inherent in CRP disparities, this work contributes to a greater understanding of the biological mechanisms underlying racial disparities in leading causes of morbidity and mortality in the United States.

Racial Differences in Elevated C-Reactive Protein Among US Older Adults.

OBJECTIVES: To investigate racial differences in elevated C-reactive protein (CRP) and the potential factors contributing to these differences in US older men and women. DESIGN: Nationally representative cohort study. SETTING: Health and Retirement Study, 2006 to 2014. PARTICIPANTS: Noninstitutionalized non-Hispanic black and white older adults living in the United States (n = 13 517). MEASUREMENTS: CRP was categorized as elevated (>3.0 mg/L) and nonelevated (≤3.0 mg/L) as the primary outcome. Measures for demographic background, socioeconomic status, psychosocial factors, health behaviors, and physiological health were examined as potential factors contributing to race differences in elevated CRP. RESULTS: Median CRP levels (interquartile range) were 1.67 (3.03) mg/L in whites and 2.62 (4.95) mg/L in blacks. Results from random effects logistic regression models showed that blacks had significantly greater odds of elevated CRP than whites (odds ratio = 2.58; 95% confidence interval [CI] = 2.20-3.02). Results also showed that racial difference in elevated CRP varied significantly by sex (predicted probability [PP] [white men] = 0.28 [95% CI = 0.27-0.30]; PP [black men] = 0.38 [95% CI = 0.35-0.41]; PP [white women] = 0.35 [95% CI = 0.34-0.36]; PP [black women] = 0.49 [95% CI = 0.47-0.52]) and remained significant after risk adjustment. In men, the racial differences in elevated CRP were attributable to a combination of socioeconomic (12.3%) and behavioral (16.5%) factors. In women, the racial differences in elevated CRP were primarily attributable to physiological factors (40.0%). CONCLUSION: In the US older adult population, blacks were significantly more likely to have elevated CRP than whites; and the factors contributing to these differences varied in men and women.

Do Race and Everyday Discrimination Predict Mortality Risk? Evidence From the Health and Retirement Study.

Everyday discrimination is a potent source of stress for racial minorities, and is associated with a wide range of negative health outcomes, spanning both mental and physical health. Few studies have examined the relationships linking race and discrimination to mortality in later life. We examined the longitudinal association among race, everyday discrimination, and all-cause mortality in 12,081 respondents participating in the Health and Retirement Study. Cox proportional hazards models showed that everyday discrimination, but not race, was positively associated with mortality; depressive symptoms and lifestyle factors partially accounted for the relationship between everyday discrimination and mortality; and race did not moderate the association between everyday discrimination and mortality. These findings contribute to a growing body of evidence on the role that discrimination plays in shaping the life chances, resources, and health of people, and, in particular, minority members, who are continuously exposed to unfair treatment in their everyday lives.

Understanding the Meaning of Food in People With Type 2 Diabetes Living in Northern Appalachia.

PURPOSE: Food and eating convey memories and feelings and serve important functions in creating and maintaining relationships. Given the increasing rate of diabetes in the United States, research understanding the meaning of food may shed light on how patients negotiate everyday food choices while managing type 2 diabetes. The purpose of this qualitative study was to explore the meaning of food among adults with type 2 diabetes living in Northern Appalachia. METHODS: In-depth, face-to-face interviews were conducted with type 2 diabetes patients. Interviews were coded and analyzed via thematic analysis. RESULTS: Nineteen adults with type 2 diabetes (mean age 68.7 ± 10.6 years, mean A1C 7.4 ± 1.4%, mean diabetes duration 10.9 ± 11.9 years, 52.6% female, 100% white) participated in the study. Qualitative analysis revealed three themes: 1) "Sustaining Life:" Food and the Demands of Diabetes Management, in which participants described the role of food as operational and said that eating was dictated by time rather than hunger or pleasure; 2) "Diabetes Feels Like a Yield Sign:" Diabetes Changes Perceptions of Food, Enjoyment, and Social Relationships, in which most participants described a negative or ambivalent relationship with food after their diabetes diagnosis; and 3) "Food is Everywhere; It's Seducing:" Struggling With Diabetes Management in a Fast-Food Culture, in which participants discussed how the American fast-food culture was in direct conflict with the demands of diabetes and described how they struggled to follow a healthful diet in a culture that advertised the opposite in many venues. CONCLUSION: Adults with diabetes may benefit from education that addresses both the personal and sociocultural factors that guide food choices.

The Role of Leisure Activities in the Relationship Between Marital Transition in Later Midlife and Psychological Well-Being Trajectories.

This study examined the levels and rates of changes in psychological well-being for middle-aged adults of different statuses or marital transitions. The moderating effects of different leisure activities were also tested. Longitudinal data on 1,270 persons aged 50 to 65 years at baseline from the Taiwan longitudinal study on aging were analyzed. Adults who were stably unmarried or unpartnered reported worse mental health at baseline, but their psychological well-being improved over time. The trajectory of depressive symptoms fluctuated markedly in adults who became widowed during our observation period. Engagement in physical, cognitive, or social activities was significantly associated with participants' psychological well-being. Participation in religious activities was significantly associated with life satisfaction and decreased depressive symptoms for those undergoing bereavement. Findings from this study suggest that social and physical activities, among the four selected leisure activities, have the greatest association between decreasing depressive symptoms and increasing life satisfaction, respectively. Religious activities, in particular, may improve psychological well-being in bereaved middle-aged and older adults.

Depressive symptom trajectories in the first 10 years of diabetes diagnosis: antecedent factors and link with future disability in Taiwan.

PURPOSE: This study identified depressive symptom trajectories in the years after diabetes diagnosis, examined factors that predict the probability for people following a specific trajectory, and investigated how the trajectories are associated with subsequent disability. METHODS: We drew data from a nationally representative survey in Taiwan to identify adults aged 50 and older diagnosed with diabetes; 487 patients newly diagnosed with diabetes during 1996-2007 were included. Time axis was set to zero when diabetes was first reported in any given wave in the survey, and data related to depressive symptoms after that were recorded. We used group-based semi-parametric mixture models to identify trajectories of depressive symptoms and multinomial logistic regressions to examine factors associated with the trajectories. RESULTS: Older adults with newly diagnosis of diabetes in Taiwan follow different trajectories of depressive symptoms over time. Being female, lower educated, not married/partnered, with lower self-rated health, hospitalizations, more limitations in physical function, less regular exercise before diagnosis, and not regularly using anti-diabetic medication at the beginning of their diagnosis were factors associated with increasing or high stable depressive symptom trajectories. Those who experienced high depressive symptoms were more likely than individuals with stable depressive symptoms to have physical limitations in the last follow-up interview. CONCLUSIONS: Depressive symptom trajectories after diabetes diagnosis were associated with select sociodemographic, health, and lifestyle factors before diagnosis, and also predicted subsequent disability. Risk groups identified in the present study may be used for personalized diabetes care that prevents diabetes-related distress and future disability.

The Short- and Long-Term Effects of Psychobehavioral Correlates in Buffering Diabetes-Related Cognitive Decline.

BACKGROUND/PURPOSE: The short- and long-term impacts of behavioral and psychological factors on the diabetes and cognitive function relationship are not fully understood. This study examined levels and rates of change in age trajectories of cognitive function in middle-aged and older adults with and without diabetes who participated in different health behaviors. METHODS: Participants aged 53 and above with and without diabetes were drawn from the 1999 Taiwan Longitudinal Study of Aging (N = 4076, mean age 69.3, SD = 9.1). Cognitive function was measured with the 9-item Short Portable Mental Status Questionnaire (SPMSQ) in 1999, 2003, and 2007. Lifestyle and psychosocial variables were measured in 1996, 1999, and 2003 as lagged time-varying covariates in random effects model analyses. RESULTS: Adults with diabetes had significantly lower levels of (ßdiabetes = -.212, p < .001) cognitive function, compared to those without diabetes, net of the effects of key sociodemographic and comorbidity covariates. The addition of exercise, social support, and depressive symptoms to the analytic models reduced the diabetes impact to non-significance. Exercise alone explained 33 % of the variation in the age trajectory. Only diet behavior showed a significant interaction effect with age (ßdiet*age = .011, p < .05). CONCLUSIONS: This population-based longitudinal study provides evidence for the prospective effects of psychobehavioral factors in preserving cognitive function for at least 3 to 4 years in adults with or without diabetes, a result supporting psychoneuroendocrinology studies linking stress and stress hormones to cognitive function, potentially informing treatment options for diabetes care.

Impact of traditional Chinese medicine on age trajectories of health: evidence from the Taiwan Longitudinal Study on Aging.

Although traditional Chinese medicine (TCM) is widely used, its effect on health outcomes is not well understood. This study employed a cohort sequential design to investigate levels and rates of change in health from midlife to older adulthood in TCM users and nonusers. A sample of 1,302 community-dwelling adults aged 53 to 80 was selected from individuals interviewed in the 1999 Taiwan Longitudinal Study on Aging (TLSA) and reinterviewed in 2003 and 2007. TCM users were identified as participants who reported visiting a Chinese medicine clinic in the year before each of the three interviews. Health outcomes included physical function, self-rated health, cognitive function, and depressive symptoms. Approximately one in five adults reported that they used TCM in at least one wave of the 3 interview years, but less than one in twenty across all waves. Controlling for time-varying sociodemographic and health conditions, levels and rates of change in physical and cognitive function did not differ according to TCM use. Although adults who reported using TCM had higher depressive symptoms (ßTCM = 0.979, 95% confidence interval (CI) = 0.200-1.758) and poorer self-rated health (ßTCM = -0.267, 95% CI = -0.267 to -0.081) at baseline, their rates of change in these outcomes did not differ from those who did not use TCM. Subgroup analyses revealed that TCM use benefited adults with higher depressive symptoms by attenuating worsening depressive symptoms (ßTCM ×Age = -0.221, 95% CI = -0.434 to -0.007). Further research aimed at understanding the specific mechanisms by which TCM affects health outcomes is warranted.

Prevalence of diabetes and associated obesity in Pennsylvania adults, 1995-2010.

INTRODUCTION: This study examined trends in the prevalence and sociodemographic distributions of diabetes and the associations of diabetes with obesity over time in adult Pennsylvanians from 1995 through 2010. METHODS: We used Behavioral Risk Factor Surveillance Survey data collected from 1995 through 2010. Diabetes prevalence was assessed by self-report of physician diagnosis. Obesity was assessed by body mass index computed from self-report of height and weight. State-level data for diabetes and associated obesity prevalence from 1995 through 2010 were collected for each year. Data on sociodemographic factors (age, sex, race, income, education) and 1 known disease risk factor (obesity) were also collected. Logistic regression modeling was used to examine associations between diabetes, sociodemographic factors, and obesity. RESULTS: Diabetes prevalence in Pennsylvania, which increased from 5.6% in 1995 to 10.5% in 2010, followed national trends but exceeded the national prevalence each year by approximately 0.6 percentage points for 12 of the 16 years. The increase in prevalence was not equal across all socioeconomic groups. Obesity became a more dominant risk factor for diabetes during these 16 years. CONCLUSION: The burden of diabetes and obesity in Pennsylvania is substantial and increasing. Program managers and policy makers in Pennsylvania should consider these trends when allocating limited resources and designing programs for reducing diabetes-related illness. Other states may consider similar studies to monitor the prevalence of diabetes and determine whether disparities are changing and whether programs and resources should also shift.

Fundamental resource dis/advantages, youth health and adult educational outcomes.

Recent studies find lasting effects of poor youth health on educational attainment but use young samples and narrow life course windows of observation to explore outcomes. We apply a life course framework to three sets of Health and Retirement Study birth cohorts to examine early health status effects on education and skills attainment measured late in life. The older cohorts that we study were the earliest recipients of U.S. policies promoting continuing education through the GI Bill, community college expansions and new credentials such as the GED. We examine a wide range of outcomes but focus on GEDs, postsecondary school entry and adult human capital as job-related training. We find that older U.S. cohorts had considerable exposure to these forms of attainment and that the effects of youth health on them vary by outcome: health selection and ascription group effects are weak or fade, respectively, in outcomes associated with delayed or adult attainment. However, poorer health and social disadvantage in youth and barriers associated with ascription carry forward to limit attainment of key credentials such as diplomas and college degrees. We find that the human capital - health gradient is dynamic and that narrow windows of observation in existing studies miss much of it. National context also matters for studying health-education linkages over the life course.

Older Adults' Perceived Challenges With Health Care Providers Treating Their Type 2 Diabetes and Comorbid Conditions.

Type 2 diabetes and comorbidity represent serious health problems to the aging population. This qualitative study aimed to describe older adults' perceived challenges with providers treating their type 2 diabetes and other chronic conditions. Older adults perceived a general unwillingness from their providers to treat their multiple health conditions and address their individual preferences for care. Older adults may require more in-depth communication with their providers in addition to individualized treatment plans that address their preferences for comorbidity management.

Listening to Older Adults' Values and Preferences for Type 2 Diabetes Care: A Qualitative Study.

Individuals' values and preferences have a considerable impact on their motivation and, therefore, their willingness to follow treatment recommendations. This qualitative study aimed to describe older adults' values and preferences for type 2 diabetes care. Older adults valued an effective physician-patient treatment relationship and quality of life in their diabetes care. They preferred physicians who knew them as a person and were honest about their diabetes treatment and progression of the illness. When developing treatment plans, providers should assess the effect that treatment will likely have on older adults' health, while explicitly acknowledging their values and preferences for care as a prelude to better patient-centered care and potentially shared decision-making.

BMI change patterns and disability development of middle-aged adults with diabetes: a dual trajectory modeling approach.

BACKGROUND: Few longitudinal studies have examined associations between body mass index (BMI) changes in adults with diabetes and the development of disability. OBJECTIVE: To investigate association patterns between BMI and disability in middle-aged adults with diabetes. DESIGN AND SETTING: Retrospective cohort design with data from the 1992-2006 Health and Retirement Study (HRS). A group-based joint trajectory method identified distinct BMI change trajectories and their link to subsequent disability trajectories. PARTICIPANTS: U.S. nationally representative adults aged 51-61 who reported a diagnosis of diabetes in the 1992 HRS (N = 1,064). MEASUREMENTS: BMI and self-reported disability score were the main variables. Sociodemographic, clinical, behavioral, and diabetes-related factors were also examined. RESULTS: Four distinct weight trajectories (stable normal weight, 28.7 %; stable overweight, 46.2 %; loss and regain obese, 18.0 %; weight cumulating morbidly obese, 7.1 %) and three disability trajectories (little or low increase, 34.4 %; moderate increase, 45.4 %; chronic high increase, 20.2 %) best characterized the long-term patterns of BMI and disability change in middle-aged adults with diabetes. Adults in stable normal weight had the highest probability of being in the little/low increase disability group; however, one in five adults in that group progressed into chronic high disability, a higher proportion compared to the stable overweight group. CONCLUSIONS: Although there were various ways in which the two trajectories were linked, the beneficial impacts of optimizing weight in adults with diabetes were supported. In addition, the complexity of diabetes control in those with relatively normal weight was highlighted from this study.

Barriers to CRC screening among Latino adults in Pennsylvania: ACCN results.

OBJECTIVES: To describe knowledge of and barriers to colorectal cancer (CRC) screening by sex and geography among Latino adults in Pennsylvania. METHODS: Eighty-two Latinos >50 years old engaged in one of 8 focus groups. Focus groups consisted of 4 components. Focus group data were audiotaped, transcribed, and grouped into thematic units using content analysis. RESULTS: We found significant differences in the reported barriers to CRC screenings by sex and geography. Identified barriers were placed into 5 domains: (1) physical environment, (2) structural, (3) sociocultural, (4) individual level, and (5) physician related. CONCLUSIONS: A targeted approach for CRC screening among Latinos may be better than the nontargeted approach.

Diabetes-related change in physical disability from midlife to older adulthood: evidence from 1996-2003 Survey of Health and Living Status of the Elderly in Taiwan.

One in five older adults in Taiwan have been diagnosed with diabetes. This study drew on disability data for 5121 nationally representative middle-aged and older adults from the 1996-2003 Survey of Health and Living Status of the Elderly in Taiwan (SHLSET). By employing cohort sequential design and multilevel models, it combined cross-sectional and longitudinal evidence to characterize the age trajectory of physical disability from midlife to older adulthood and to discern the extent to which diabetes contributes to the variation in that trajectory. The main effects of diabetes and diabetes × age interaction in the fully controlled model provide evidence that diabetes independently and consistently changes physical functioning over and above natural aging processes in Taiwanese adults. In addition, while adding diabetes in the age trajectory of physical disability explained 3.2% and 1.6% of the variance in levels of and linear changes in physical disability trajectory, respectively, further adding follow-up status, sociodemographic factors and comorbidities altogether explained 40.5% and 29.1% of the variance in levels of and linear changes in that trajectory. These results imply that preventing the incidence of diabetes-related comorbidities may reduce the deterioration in both levels of and rates of change in physical disability.

Physical disability trajectories in older Americans with and without diabetes: the role of age, gender, race or ethnicity, and education.

PURPOSE: This research combined cross-sectional and longitudinal data to characterize age-related trajectories in physical disability for adults with and without diabetes in the United States and to investigate if those patterns differ by age, gender, race or ethnicity, and education. DESIGN AND METHODS: Data were examined on 20,433 adults aged 51 and older from the 1998 to 2006 Health and Retirement Study. Multilevel models and a cohort-sequential design were applied to quantitatively depict the age norm of physical disability after age 50. RESULTS: Adults with diabetes not only experience greater levels of physical disability but also faster rates of deterioration over time. This pattern is net of attrition, time-invariant sociodemographic factors, and time-varying chronic disease conditions. Differences in physical disability between adults with and without diabetes were more pronounced in women, non-White, and those of lower education. The moderating effects of gender and education remained robust even after controlling for selected covariates in the model. IMPLICATIONS: This study highlighted the consistently greater development of disability over time in adults with diabetes and particularly in those who are women, non-White, or adults of lower education. Future studies are recommended to examine the mechanisms underlying the differential effects of diabetes on physical disability by gender and education.

Gender differences in functional limitations in adults living with type 2 diabetes: biobehavioral and psychosocial mediators.

BACKGROUND: Differences in functional limitations between adults with and without diabetes are more evident in women than they are in men. PURPOSE: This study aims to investigate if there are gender differences in biological, behavioral, and psychosocial variables, and how these gender-related variables explain the gender-functional limitations relationship in adults with type 2 diabetes. METHODS: We drew data on 1,619 adults with type 2 diabetes from the Health and Retirement Study and its diabetes-specific mail survey. The fit of a series of mediation models to the data was assessed by structural equation modeling. RESULTS: Although women had better diet and blood glucose self-monitoring behaviors than did men, they reported less favorable body mass index, glycosylated hemoglobin (HbA1c) value, blood pressure, early complications, exercise behaviors, perceived control, self-efficacy, coping, depressive symptoms, and family support than did men. Psychosocial factors made an indirect contribution in the gender-functional limitations relationship by way of their strong association with biological and behavioral factors, two factors that directly and completely mediated the gender-functional limitations relationship. CONCLUSIONS: Interventions promoting psychosocial well-being and empowering perceived diabetes control, coping, and self-efficacy in women with type 2 diabetes may help improve biological and behavioral determinants, and further, their long-term functional health.
