Complementary health approaches for health and wellness in midlife and older US adults

OBJECTIVES To characterize the use of complementary health approaches (CHA) and examine the perceived benefits of using CHA by reason for use among midlife and older adults. STUDY DESIGN Analysis of 2012 National Health Interview Survey data, a nationally representative US sample using cross-tabulations with design-based F-tests and multiple logistic regression. The analytic sample included adults aged over 50 years (N=14,849). MAIN OUTCOME MEASURES The proposed benefits of using CHA included: (1) better control over health, (2) reduced stress/relaxation, (3) better sleep, (4) feeling better emotionally, (5) coping with health problems, (6) improved health/feeling better, and (7) improved relationships. RESULTS Overall, 31% of this sample of midlife and older US adults had used CHA in the past year. Among users, 15% had used CHA for treatment only, 40% for wellness only, and 45% for combined wellness and treatment. Herbs (60%), chiropractic (28%), massage (22%), and yoga (19%) were the most common CHA. Wellness-only and combined users had significantly higher odds of reporting that CHA conferred benefit compared with treatment-only users. CONCLUSIONS CHA are used by nearly a third of midlife and older adults and are perceived to provide substantial benefit. Integrating CHA as part of a healthy lifestyle has the potential to contribute to healthy aging among midlife and older adults.

Validating pharmaceutical product claims: questions a formulary committee should ask.

Abstract Claims, justifying the acceptance and placement of new products on health system formularies, are all too often presented in terms that are either unverifiable or only verifiable in a timeframe that is of no practical benefit to formulary committees. One solution is for formulary committees to request that (i) all predictive claims made should be capable of empirical testing and (ii) manufacturers in making submissions should be asked to submit a protocol that details how their claims are to be assessed. Evaluation of claims can provide not only a significant input to ongoing disease area and therapeutic reviews, but can also provide a needed link to comparative effectiveness research and value-based healthcare. This paper presents a set of protocol standards (PROST) together will questions that should be addressed in a protocol review.

Gender Differences in the Use of Complementary and Alternative Medicine and Their Association With Moderate Mental Distress in U.S. Adults With Migraines/Severe Headaches

We examined whether the prevalence of complementary and alternative medicine (CAM) use varies by gender, and assessed the interaction of gender and CAM use on moderate mental distress (MMD) in U.S. adults with migraines/severe headaches.

Racial/Ethnic Differences in the Use of Complementary and Alternative Medicine in US Adults With Moderate Mental Distress: Results From the 2012 National Health Interview Survey

Objectives: To examine the prevalence of complementary and alternative medicine (CAM) use by race/ethnicity and to identify sociodemographic and health-related factors associated with CAM use among US adults with moderate mental distress (MMD). Methods: We analyzed data from the 2012 National Health Interview Survey (NHIS). We used data for 6016 noninstitutionalized US adults with MMD (3492 non-Hispanic whites, 953 non-Hispanic blacks, 1078 Hispanics, 268 Asians, and 225 others consisted of American Indian, Alaska Native, and those reporting multiple races). The 2012 NHIS asks about 36 types of CAM use in the past 12 months. We constructed (1) overall, any CAM use; (2) 5 major types of CAM use; and (3) individual types of CAM use indicators. Using a cross-sectional design with complex survey techniques, we estimated race/ethnicity-specific CAM prevalence, and odds of past year CAM use by race/ethnicity, sociodemographic, and health-related factors. Results: Nearly 40% of adults with MMD used CAM in the past year compared with 32% of those without MMD (P < .001). In adults with MMD, past year CAM use differed by race/ethnicity, ranging from 24.3% (blacks) to 44.7% (Asians) and 46.8% (others) (P < .001). Being younger, female, living in the west, higher education, being employed, more than 4 ambulatory care visits, and functional limitations were associated with higher odds of CAM use (P < .01). Conclusions: Adults with MMD use CAM more frequently than those without MMD. In addition, CAM use was significantly differed by race/ethnicity in adults with MMD. This underscores the need for good patient-provider communication and suggests opportunity for dialogue about integration between conventional providers and CAM practitioners to facilitate optimal mental health care.

Health Literacy as a Social Determinant of Health in Asian American Immigrants: Findings from a Population-Based Survey in California

BackgroundAsian American immigrants have a lower level of health literacy than non-Latino whites, but their level of health literacy and its impact on health outcomes may differ among subgroups.ObjectiveWe investigated the level of health literacy across five subgroups of Asian American immigrants and explored the association between health literacy and self-rated health status and symptoms of depression.DesignWe utilized a cross-sectional survey research design and a population-based sampling strategy using the 2007 California Health Interview Survey (CHIS).ParticipantsWe sampled 30,615 non-Latino whites and 3,053 Asian American immigrants (1,058 Chinese, 598 Koreans, 534 Filipinos, 416 South Asians, and 447 Vietnamese).Main MeasuresWe used two questions as proxy measures to assess the level of health literacy in non-Latino whites and in both aggregated and disaggregated Asian American immigrant groups. We then investigated the effect of health literacy on two main health outcomes: self-rated health status and depression symptoms.Key ResultsThe level of health literacy varied across the five subgroups of Asian American immigrants. Chinese, Korean, and Vietnamese groups had the lowest levels of health literacy, while Filipinos showed the highest level. Health literacy was positively correlated with health status in Chinese and Korean immigrants, and negatively correlated with depression symptoms in Korean and South Asian immigrants.ConclusionWe found heterogeneity in health literacy among Asian American immigrants and found that health literacy had varying associations with health outcomes. The aggregated Asian American immigrant group results may mask the true health disparities that each Asian American immigrant group faces. Koreans were the only group found to have a significant association between the proxy for health literacy and both health outcomes. Further research is needed to better understand the causes of heterogeneity and to investigate health literacy as a critical determinant of immigrant health.Asian American immigrants have a lower level of health literacy than non-Latino whites, but their level of health literacy and its impact on health outcomes may differ among subgroups.

Effects of depression screening on diagnosing and treating mood disorders among older adults in office-based primary care outpatient settings: An instrumental variable analysis

Existing literature shows mixed findings regarding the efficacy and effectiveness of depression screening, and relatively little is known about the effectiveness of depression screening among older adults in primary care visits in the U.S. This study examines the effects of depression screening on the three following outcomes: mood disorder diagnoses, overall antidepressant prescriptions, and potentially inappropriate antidepressant prescriptions among older adults ages 65 or older in office-based outpatient primary care settings. We used data from 2010-2012 National Ambulatory Medical Care Survey (NAMCS), a nationally representative sample of office-based primary care outpatient visits among older adults (n=9,313 unweighted). We employed an instrumental variable approach to control for selection bias in our repeated cross-sectional population-based study. Injury prevention and stress management were selected as instrumental variables, as they were considered completely exogenous to outcomes of interests using conceptual and statistical criteria. We conducted multivariate bivariate probit (biprobit) regression analyses to investigate the effect of depression screening on each outcome, when controlled for other covariates. We found that depression screening was negatively associated with potentially inappropriate antidepressant prescriptions (β=-2.17; 95% CI -2.80 to -1.53; p<0.001). However, no significant effect of depression screening on diagnosis of mood disorders and overall antidepressant prescriptions was found. Overall, depression screening had a negative effect on potentially inappropriate antidepressant prescriptions. Primary care physicians and other healthcare providers should actively utilize depression screening to minimize potentially inappropriate antidepressant prescriptions in older adult patients.

Racial Differences in Minnesota Nursing Home Residents’ Quality of Life: The Importance of Looking Beyond Individual Predictors

Objectives: The aim of this study is to investigate racial differences in nursing home (NH) residents’ quality of life (QOL) at the resident and facility levels. Method: We used hierarchical linear modeling to identify significant resident- and facility-level predictors for racial differences in six resident-reported QOL domains. Data came from the following: (a) resident-reported QOL (n = 10,929), (b) the Minimum Data Set, and (c) facility-level characteristics from the Minnesota Department of Human Services (n = 376). Results: White residents reported higher QOL in five of six domains, but in full models, individual-level racial differences remained only for food enjoyment. On the facility level, higher percentage of White residents was associated with better scores in three domains, even after adjusting for all characteristics. Discussion: Racial differences in QOL exist on individual and aggregate levels. Individual differences are mainly explained by health status. The finding that facility racial composition predicts QOL more than individual race underscores the importance of examining NH structural characteristics and practices.

Cancer literacy as a mediator for cancer screening behaviour in Korean adults

This study investigates the cancer literacy level in Korean adults and examines whether cancer literacy plays a mediating role in the relationship between population characteristics and cancer screening behaviours. We collected data from 585 community-dwelling adults in Korea using self-administered surveys and face-to-face interviews from October to December in 2009. Guided by Andersens behavioural model, we used a structural equation model to estimate the effect of cancer literacy as a mediator and found that cancer literacy mediated cancer screening behaviour. In the individual path analysis models, cancer literacy played a significant mediating role for the use of eastern medicine, fatalism, health status and the number of chronic diseases. When controlling for other relevant covariates, we found that in the optimal path model, cancer literacy played a mediating role in the relationship between the use of eastern medicine and self-rated health status as well as cancer screening behaviour. Thus, developing community-based cancer education programmes and training clinical practitioners in eastern medicine clinics about the importance of informing their patients about regular cancer screening may be an option to boost cancer literacy and screening behaviour in Korea.

Complementary and Alternative Medicine in U.S. Adults with Diabetes: Reasons for Use and Perceived Benefits.

Although complementary and alternative medicine (CAM) is increasingly used, little is known about the reasons for CAM use (treatment, wellness, or both), or the self‐reported perceived benefits among US adults with diabetes. In this study we estimated prevalence rates of overall and specific types of CAM, as well as the perceived benefits of CAM, by reason for use among US diabetic adults.

Complementary and integrative healthcare for patients with mechanical low back pain in a U.S. hospital setting

OBJECTIVES Complementary and integrative healthcare (CIH) is commonly used to treat low back pain (LBP). While the use of CIH within hospitals is increasing, little is known regarding the delivery of these services within inpatient settings. We examine the patterns of CIH services among inpatients with mechanical LBP in a hospital setting. METHODS This is a retrospective, practice-based study conducted at Abbot Northwestern hospital in Minnesota. Using electronic health record data from July 2009 to December 2012, 8095 inpatients with mechanical LBP were identified using ICD-9 codes. We classified patients by reason for hospitalization. We examined demographic and clinical characteristics by receipt of CIH services. Then, we estimated the prevalence of types of CIH delivered and clinical foci for CIH visits among inpatients with mechanical LBP. RESULTS Most inpatients with mechanical LBP (>90%) were hospitalized for surgical procedures. Overall, 14.2% received inpatient CIH services. All demographic and clinical characteristics differed by receipt of CIH (P<0.001), except race/ethnicity. CIH recipients were in poorer health than those who did not. Most commonly delivered CIH services were massage (62.1%), relaxation techniques (42.0%) and acupuncture (25.7%). Pain (45.1%), relaxation (17.5%), and comfort (8.2%) were the top three reasons for CIH visits. CONCLUSION There are important differences between CIH recipients and non-CIH recipients among patients with mechanical LBP within a hospital setting. The reasons documented for CIH visits included addressing physical, emotional and/or mental conditions of patients. Future studies are needed to determine the effectiveness of CIH services health and wellbeing outcomes in this population.
