Do pre-transplant cultural factors predict health-related quality of life after kidney transplantation?

BACKGROUND: Post-transplant health-related quality of life (HRQOL) is associated with health outcomes for kidney transplant (KT) recipients. However, pretransplant predictors of improvements in post-transplant HRQOL remain incompletely understood. Namely, important pretransplant cultural factors, such as experience of discrimination, perceived racism in healthcare, or mistrust of the healthcare system, have not been examined as potential HRQOL predictors. Also, few have examined predictors of decline in HRQOL post-transplant. METHODS: Using data from a prospective cohort study, we examined HRQOL change pre- to post-transplant, and novel cultural predictors of the change. We measured physical, mental, and kidney-specific HRQOL as outcomes, and used cultural factors as predictors, controlling for demographic, clinical, psychosocial, and transplant knowledge covariates. RESULTS: Among 166 KT recipients (57% male; mean age 50.6 years; 61.4% > high school graduates; 80% non-Hispanic White), we found mental and physical, but not kidney-specific, HRQOL significantly improved post-transplant. No culturally related factors outside of medical mistrust significantly predicted change in any HRQOL outcome. Instead, demographic, knowledge, and clinical factors significantly predicted decline in each HRQOL domain: physical HRQOL-older age, more post-KT complications, higher pre-KT physical HRQOL; mental HRQOL-having less information pre-KT, greater pre-KT mental HRQOL; and, kidney-specific HRQOL-poorer kidney functioning post-KT, lower expectations for physical condition to improve, and higher pre-KT kidney-specific HRQOL. CONCLUSIONS: Instead of cultural factors, predictors of HRQOL decline included demographic, knowledge, and clinical factors. These findings are useful for identifying patient groups that may be at greater risk of poorer post-transplant outcomes, in order to target individualized support to patients.

Examination of ecological validity of intuitive eating.

BACKGROUND: Intuitive eating, which involves following internal cues of hunger and satiety to guide eating choices, would be better understood if studied at the individual momentary level instead of globally or cross-sectionally. The current study employed ecological momentary assessment (EMA) to examine the ecological validity of a popular intuitive eating measure, the Intuitive Eating Scale (IES-2). METHOD: College males and females completed a baseline assessment of trait levels of intuitive eating as measured by the IES-2. Participants then followed a seven-day EMA protocol where they completed brief smart phone assessments about intuitive eating and related constructs while in their natural daily environments. Participants were asked to complete recordings before and after eating about their state level of intuitive eating at that moment. RESULTS: Among 104 participants, 87.5% were female, mean age was 24.3, and mean BMI was 26.3. Baseline trait level intuitive eating was significantly correlated with state level intuitive eating reported across EMA recordings, with some evidence suggesting that correlations were stronger before eating compared to after eating. Intuitive eating generally was related to less negative affect, fewer eating restrictions, and more anticipated taste enjoyment before eating, as well as less guilt and regret after eating. DISCUSSION: Individuals who reported high trait levels of intuitive eating also reported following their internal cues for hunger and satiety and had less guilt, regret, and negative affect surrounding eating in their naturalistic environments, thereby supporting the ecological validity of the IES-2.

A qualitative exploration of perceived barriers and facilitators to following an intuitive eating style.

BACKGROUND: Intuitive eating involves following internal cues of hunger and satiety to guide eating choices as opposed to responding to external signals, strong emotions, or dietary rules. This style of eating has consistently been shown to be related to better physical and psychological health indicators, and more interventions are being designed and studied to promote this eating style. The current study aimed to identify anticipated facilitators and barriers to following this style of eating among a group of college students enrolled in a larger study of intuitive eating. METHOD: Following a week of tracking their current eating as part of a larger study, college students read a description of intuitive eating. They then answered three open-ended questions about following intuitive eating including facilitators, barriers, and perceived ability to follow long term. Responses were coded using thematic analysis to identify themes across responses. RESULTS: Among 100 participants, 86 % were female, 46 % were Hispanic (41 % non-Hispanic White, 13 % other race/ethnicity), mean age was 24.3 years, and mean body mass index was 26.2. The most commonly anticipated participant-reported facilitators of intuitive eating were being in touch with the body's needs and hunger cues, positive perceptions of intuitive eating, and health considerations. The most commonly anticipated barriers were logistical constraints (e.g., busyness and mealtimes), difficulty with hunger cues and reactions to food, and negative perceptions of intuitive eating. The majority of participants (64 %) would consider following this style of eating long term. DISCUSSION: This study provides information that can be used to improve efforts aimed at promoting intuitive eating to college students, including marketing intuitive eating interventions, and clarifying misunderstandings of its key tenets that might serve as barriers.

Assessing hedonic hunger among Chinese adults using the Power of Food Scale: Psychometric properties and cross-cultural invariance between China and the US.

Hedonic hunger refers to food consumption for pleasure without biological energy deficits. The Power of Food Scale (PFS) is a well-developed self-report instrument assessing hedonic hunger. The present study aimed to translate and validate the PFS into simplified Chinese (C-PFS) and examine its psychometric properties among Chinese adults. A total of 773 participants (51.1 % men, M age = 24.98 years, SD = 6.10) were recruited in the present study from college and community populations. Consistent with the previous studies, confirmatory factor analysis showed that the C-PFS had three factors: food present, food available, and food tasted. In addition, a Cronbach's alpha of 0.92 and an ICC of 0.86 suggested that the C-PFS has good internal consistency and test-retest reliability. In terms of convergent validity, the scores of C-PFS correlated significantly with disordered eating symptomatology and loss of control over eating. Measurement invariance tests showed that the C-PFS was invariant across gender and sample source groups in the Chinese sample. In addition, a U.S. sample of 490 college students (26.6 % men, M age = 21.41 years, SD = 5.45) was used to test the measurement invariance across countries, and results suggested a partial invariance across college students from China and those from the U.S. In conclusion, the C-PFS can be a useful tool for measuring hedonic hunger among adults in China, and there may be cultural differences in the measurement of the PFS in college students across China and the U.S.

Protocol for the AKT-MP trial: Access to Kidney Transplantation in Minority Populations.

Background: Kidney transplant (KT) is the optimal treatment for kidney failure (KF), and although completion of KT evaluation is an essential step in gaining access to transplantation, the process is lengthy, time consuming, and burdensome. Furthermore, despite similar referral rates to non-Hispanic Whites, both Hispanic/Latinos and American Indians are less likely to be wait-listed or to undergo KT. Methods: The Access to Kidney Transplantation in Minority Populations (AKT-MP) Trial compares two patient-centered methods to facilitate KT evaluation: kidney transplant fast track (KTFT), a streamlined KT evaluation process; and peer navigators (PN), a peer-assisted evaluation program that incorporates motivational interviewing. This pragmatic randomized trial will use a comparative effectiveness approach to assess whether KTFT or PN can help patients overcome barriers to transplant listing. We will randomly assign patients to the two conditions. We will track participants' medical records and conduct surveys prior to their initial evaluation clinic visit and again after they complete or discontinue evaluation. Conclusion: Our aims are to (1) compare KTFT and PN to assess improvements in kidney transplant (KT) related outcomes and cost effectiveness; (2) examine how each approach effects changes in cultural/contextual factors, KT concerns, KT knowledge, and KT ambivalence; and (3) develop a framework for widespread implementation of either approach. The results of this trial will provide key information for facilitating the evaluation process, improving patient care, and decreasing disparities in KT.
