ABSTRACT

Objectives: This paper is an examination of cancer/health communication factors (i.e. cancer/health information seeking, patient-provider communication (PPC), cancer screening information from providers) and screening for breast and cervical cancer among Asian Americans and five Asian ethnic groups (Chinese, Filipinos, Japanese, Koreans, Vietnamese) in comparison to Whites. Additionally, the relationship between cancer/health communication disparity and cancer screening gaps between Asian Americans and Whites was investigated.

Design: Data comes from a nationally representative sample of 2011–2014 Health Information National Trends Surveys (HINTS).

Results: Asian Americans and most Asian ethnic-groups reported significantly lower rates of cancer/health information seeking and lower evaluations for PPC as compared to Whites, though differences within Asian ethnic groups were observed (Koreans’ greater cancer/health information seeking, Japanese’ higher PPC evaluation). When the cancer/health communication factors were controlled, Asian Americans’ odds of cancer screening were increased. Especially, Asian Americans’ odds of adhering to the breast cancer screening guideline became nearly 1.4 times greater than Whites.

Conclusion: This research demonstrates that health organizations, providers, and Asian American patients’ collaborative efforts to increase the access to quality cancer information, to make culturally competent but straightforward screening recommendations, and to practice effective communication in medical encounters will contribute to diminishing cancer disparities among Asian Americans.  相似文献

BackgroundHigher vitamin D status has been associated with symptom improvement and decreased risk of various autoimmune disorders. Our objective was to determine whether higher serum 25-hydroxyvitamin D (25OHD) concentration correlated with less severe first-diagnosed bullous pemphigoid (BP) in older inpatients.MethodsThis cross-sectional study was performed from November 2012 to February 2014 among 30 consecutive older inpatients (21 women; mean ± SD, 83 ± 7 years; all Caucasian) with a de novo diagnosis of active BP recruited in the Department of Dermatology of Angers University Hospital, France. The severity of BP was graded clinically on the basis of i) the number of bullae during the first three days of hospitalization (grade 0–4, worse), and ii) the extent of the lesions (grade 0–5, worse).ResultsSixteen participants had ≤ 5 bullae at the time of diagnosis, 8 had 6–20 bullae, 3 had 20–50 bullae, and 3 had >50 bullae. The lesions were spread over 5 cutaneous areas in 5 participants (17%). The median 25OHD concentration was 23 [IQR, 16–42] nmol/L. Serum 25OHD concentration was inversely correlated with the bullae grade (ρ = − 0.38, p = 0.04) and the lesion extension grade (ρ = − 0.50, p = 0.005).ConclusionsHigher serum 25OHD concentration correlated with less severe BP prior to initiation of treatment among our sample of older inpatients. This result suggests that vitamin D may be involved in the pathophysiology of BP and could serve as prognostic biomarker of BP.  相似文献

BackgroundGrowing research documents associations between neighborhood social cohesion with better health and well-being. However, other work has identified social cohesion's “dark side” and its ability to promote negative outcomes. It remains unclear if such diverging findings are attributable to differences in study design, or other reasons. To better capture its potential heterogeneous effects, we took an outcome-wide analytic approach to examine perceived neighborhood social cohesion in relation to a range of health and well-being outcomes.MethodsData were from 12,998 participants in the Health and Retirement Study—a large, diverse, prospective, and nationally representative cohort of U.S. adults age >50. Multiple regression models evaluated if social cohesion was associated with physical health, health behavior, psychological well-being, psychological distress, and social well-being outcomes. All models adjusted for sociodemographics, personality, and numerous baseline health and well-being characteristics. To evaluate the effects of change in cohesion, we adjusted for prior social cohesion. Bonferroni correction was used to account for multiple testing.ResultsPerceived neighborhood social cohesion was not associated with most physical health outcomes (except for reduced risk of physical functioning limitations and better self-rated health) nor health behavior outcomes (except for more binge drinking). However, it was associated with numerous subsequent psychosocial well-being (i.e., higher: positive affect, life satisfaction, optimism, purpose in life, mastery, health mastery, financial mastery; reduced likelihood of infrequent contact with friends) and psychological distress outcomes (i.e., lower depression, hopelessness, negative affect, loneliness) over the 4-year follow-up period.ConclusionsWith further research, these results suggest that perceived neighborhood social cohesion might be a valuable target for innovative policies aimed at improving well-being.  相似文献

Ageing in place raises pressing questions about medication practices at home. Understanding how medication practices are integrated into older adults’ domestic settings requires an interest in where activities linked to medication take place and why. This study aimed to describe the medication practices and spatial dimensions of medication management for home-dwelling older adults after hospital discharge, using a qualitative research design. Semi-structured interviews were carried out with ten older adults aged 65 years old or more and discharged home from hospital, together with nine informal caregivers. Thematic content analysis identified two main themes dealing with the spatial dimensions of medication management in this specific context: the process of integrating medication changes into routines and familiar spaces, and the individual and collective management of medication changes linked to a renegotiation of the boundaries between public and private spaces.  相似文献
