Racial and Ethnic Variation in Complementary and Integrative Health Therapy Use Among US Veterans.

Importance: White individuals are the greatest users of complementary and integrative health (CIH) therapies in the general population, but this might partially be due to differences in age, health condition, and location. Identifying the nuances in racial and ethnic differences in care is one important step to addressing them. Objective: To evaluate racial and ethnic differences in Veterans Affairs (VA)-covered CIH therapy use in a more nuanced manner by examining the association of 5 demographic characteristics, health conditions, and medical facility locations with those differences. Design, Setting, and Participants: Retrospective cross-sectional observational study of VA health care system users, using electronic health record and administrative data at all VA medical facilities and community-based clinics. Participants included veterans with nonmissing race and ethnicity data using VA-funded health care between October 2018 and September 2019. Data were analyzed from June 2022 to April 2023. Main Outcome and Measure: Any use of VA-covered acupuncture, chiropractic care, massage therapy, yoga, or meditation/mindfulness. Results: The sample consisted of 5 260 807 veterans with a mean (SD) age of 62.3 (16.4) years and was 91% male (4 788 267 veterans), 67% non-Hispanic White (3 547 140 veterans), 6% Hispanic (328 396 veterans), and 17% Black (903 699 veterans). Chiropractic care was the most used CIH therapy among non-Hispanic White veterans, Hispanic veterans, and veterans of other races and ethnicities, while acupuncture was the most commonly used therapy among Black veterans. When not accounting for the location of the VA medical facilities in which veterans used health care, Black veterans appeared more likely to use yoga and meditation than non-Hispanic White veterans and far less likely to use chiropractic care, while those of Hispanic or other race and ethnicity appeared more likely to use massage than non-Hispanic White veterans. However, those differences mostly disappeared once controlling for medical facility location, with few exceptions-after adjustment Black veterans were less likely than non-Hispanic White veterans to use yoga and more likely to use chiropractic care. Conclusions and Relevance: This large-scale, cross-sectional study found racial and ethnic differences in use of 4 of 5 CIH therapies among VA health care system users when not considering their medical facility location. Given those differences mostly disappeared once medical facilities were accounted for, the results demonstrated the importance of considering facilities and residential locations when examining racial differences in CIH therapy use. Medical facilities could be a proxy for the racial and ethnic composition of their patients, CIH therapy availability, regional patient or clinician attitudes, or therapy availability.

Beyond depression: correlates of well-being in young adult survivors of childhood cancers.

PURPOSE: This study investigated the correlates of well-being with psychosocial and clinical factors in young adult childhood cancer survivors (YACCS) above and beyond depressive symptoms. METHODS: Participants were from the Project Forward Cohort, a population-based study of young adult survivors of childhood cancers. Participants (n = 1166, Mage = 25.1 years) were recruited through the Los Angeles Cancer Surveillance Program (Cancer Registry covering Los Angeles County). A majority received a diagnosis of leukemia (36.1%) or lymphoma (21.7%). Participants completed self-reported questionnaires at one timepoint. Multiple regression analyses were performed with well-being as the outcome variable and psychosocial and clinical variables (social support, sense of adulthood, posttraumatic growth, treatment intensity, and self-rated health) as the independent variables. Covariates included demographics (age, gender, relationship status, race/ethnicity) and depressive symptoms. RESULTS: In the multivariable model, posttraumatic growth, social support, sense of adulthood, and self-rated health were significantly associated with well-being (all ps < .05), when controlling for depressive symptoms. Treatment intensity and years since diagnosis were not significantly associated with well-being, when controlling for depressive symptoms. CONCLUSIONS: There are unique correlates of well-being above and beyond depressive symptoms among YACCS. This finding illuminates individual differences that may be associated with well-being and provides targets for intervention. IMPLICATIONS FOR CANCER SURVIVORS: Psychosocial interventions and survivorship care for YACCS should consider the broad aspects of well-being, independent of depressive symptoms.

Examining the Factor Structure of an Adapted Posttraumatic Growth Inventory in a Sample of Childhood Cancer Survivors: A Brief Report.

Posttraumatic growth (PTG) represents positive changes following a trauma, crisis, and/or psychologically distressing event. Experiencing cancer can serve as a traumatic event for patients, resulting in life changes among survivors. Various PTG measures have been used to assess post-cancer change among childhood cancer survivors (CCS), but few have been evaluated for use in this population. This study examined the factor structure of an adapted, 11-item version of the Posttraumatic Growth Inventory (PTGI) among CCS. A randomly selected subgroup of participants (N = 332) was selected from the Los Angeles Cancer Surveillance Program (mean age of 26.5 years at time of survey, mean age at diagnosis of 12 years, primarily male [53.6%], and Hispanic [51.5%]). Participants indicated the degree to which they experienced positive, negative, or no change in their life because of their cancer experience. An exploratory factor analysis (EFA) identified two factors: Appreciation of New Possibilities and Spiritual Change. The adapted, 11-item PTGI was deemed appropriate for use among CCS. Additional research is needed to confirm the use of the two-factor model with confirmatory factor analysis in an independent sample. Future research on PTG among CCS can consider spiritual change as a potential independent factor.

Insurance coverage change and survivorship care among young adult survivors of childhood cancer.

OBJECTIVE: To (1) characterize change in type of insurance coverage among childhood cancer survivors from diagnosis to survivorship and (2) examine whether insurance change is associated with cancer-related follow-up care utilization. DATA SOURCES: Participants in this study were derived from the Project Forward study, a population-based, observational study of childhood cancer survivors in Los Angeles County that used California Cancer Registry data to identify participants. STUDY DESIGN: Multivariable logistic regression models incorporating survey nonresponse weights estimated the change in the marginal predicted probabilities of insurance change and survivorship care, adjusting for demographic, socioeconomic, and clinical covariates and clustering by treating hospital. DATA COLLECTION/EXTRACTION METHODS: Study participants were diagnosed with cancer who were younger than age 20 years while living in Los Angeles County from 1996 to 2010 and were older than the age 18 years at the time of survey participation, from 2015 to 2017 (N = 1106). PRINCIPAL FINDINGS: Most participants were 18-26 years of age, male, diagnosed before 2004, Hispanic/Latino race/ethnicity, single, without children, highly educated, not employed full time, and lived with their parents at survey. Almost half (N = 529) of participants experienced insurance change from diagnosis to survivorship. Insurance change was associated with insurance coverage at diagnosis, as those who were uninsured were most likely to experience change and gain coverage during survivorship (by 51 percentage points [ppt], standard error [SE] of 0.05). Survivors who experienced any change had decreased probability of reporting a recent cancer-related follow-up care visit, a disparity that was magnified for those who lost insurance coverage (-5 ppt, SE 0.02 for those who gained coverage; -15 ppt, SE 0.04 for those who lost coverage). CONCLUSIONS: Insurance coverage change was associated with lower cancer-related follow-up care utilization. Indeed, survivors who experienced any insurance coverage change had decreased probability of having a cancer-related follow-up care visit, and this was magnified for those who lost their insurance coverage.

Acculturation, Mental Health, and Wellbeing Among Hispanic/Latinx Young Adult Survivors of Childhood Cancer.

Purpose: Ethnic disparities in childhood cancer survivor (CCS) mental health have been identified, although prior survivorship research has focused predominantly on non-Hispanic/Latinx (H/L) white survivors. Methods: This study examined the association of acculturation with depressive symptoms and wellbeing among 582 young adult H/L CCS recruited to a population-based study of CCS in Southern California. Results: In multivariable regression models adjusted for covariates, greater identification with both the Hispanic and Anglo cultures was positively associated with wellbeing (p = 0.007 and p < 0.0001, respectively), and Hispanic cultural identification was associated with fewer depressive symptoms (p = 0.04). Conclusions: Greater understanding of unique protective factors among minority CCS may inform tailored interventions promoting mental health.

Project Forward: A Population-Based Cohort Among Young Adult Survivors of Childhood Cancers.

Background: Childhood cancer survivors (CCS) face increased risk of morbidity and are recommended to receive lifelong cancer-related follow-up care. Identifying factors associated with follow-up care can inform efforts to support the long-term health of CCS. Methods: Eligible CCS (diagnosed between 1996 and 2010) identified through the Los Angeles County Cancer Surveillance Program responded to a self-report survey that assessed demographic, clinical, health-care engagement, and psychosocial risk and protective factors of recent (prior 2 years) cancer-related follow-up care. Weighted multivariable logistic regression was conducted to identify correlates of care. All statistical tests were 2-sided. Results: The overall response rate was 44.9%, with an analytical sample of n = 1106 (54.2% Hispanic; mean [SD] ages at survey, diagnosis, and years since diagnosis were 26.2 [4.9], 11.6 [5.4], and 14.5 [4.4] years, respectively). Fifty-seven percent reported a recent cancer-related visit, with lower rates reported among older survivors. Having insurance, more late effects, receipt of a written treatment summary, discussing long-term care needs with treating physician, knowledge of the need for long-term care, having a regular source of care, and higher health-care self-efficacy were statistically significantly associated with greater odds of recent follow-up care, whereas older age, Hispanic or Other ethnicity (vs non-Hispanic White), and years since diagnosis were associated with lower odds of recent care (all Ps < .05). Conclusions: Age and ethnic disparities are observed in receipt of follow-up care among young adult CCS. Potential intervention targets include comprehensive, ongoing patient education; provision of written treatment summaries; and culturally tailored support to ensure equitable access to and the utilization of care.

A Community-Based Mindfulness Intervention Among Latino Adolescents and Their Parents: A Qualitative Feasibility and Acceptability Study.

Few studies have evaluated the effectiveness of mindfulness-based meditation interventions (MBMIs) among Latino youth. Furthermore, joint parent-child participation in such programs is rare. Utilizing a community-based participatory research approach, this study evaluated the feasibility of a pilot bilingual MBMI among Latino adolescents and their parents in Los Angeles. Qualitative interviews were conducted to assess the practicality, implementation, and acceptability of the program. Challenges to attendance included health issues or conflicts with work. Several adolescents struggled with distractions from peers. However, overall responses suggest that parents and children found the program convenient and enjoyable, and perceived benefits from the curriculum. This study supports the feasibility of a MBMI among Latino family dyads.

Estimating cancer treatment intensity from SEER cancer registry data: methods and implications for population-based registry studies of pediatric cancers.

OBJECTIVE: The Intensity of Treatment Rating (ITR) Scale condenses treatment and clinical characteristics into a single measure to study treatment effects on downstream health outcomes across cancer types. This rating was originally developed for clinicians to determine from medical charts. However, large studies are often unable to access medical charts for all study participants. We developed and tested a method of estimating treatment intensity (TI) using cancer registry and patient self-reported data. METHODS: We estimated two versions of TI for a cohort of pediatric cancer survivors-one utilized information solely available from cancer registry variables (TIR) and the other included registry and self-reported information (TIS) from survey participants. In a subset of cases (n = 135) for whom the gold standard TI (TIC) was known, both TIR and TIS were compared to TIC by calculating percent agreement and weighted Cohen's kappa, overall and within cancer subtypes. RESULTS: In comparison to TIC, 71% of TI scores from both methods were in agreement (k = 0.61 TIR/0.54 TIS). Among subgroups, agreement ranged from lowest (46% TIR/39% TIS) for non-defined tumors (e.g., "Tumor-other"), to highest (94% TIR/94% TIS) for acute lymphoblastic leukemia (ALL). CONCLUSIONS: We developed a methodology to estimate TI for pediatric cancer research when medical chart review is not possible. High reliability was observed for ALL, the most common pediatric cancer. Additional validation is needed among a larger sample of other cancer subgroups. The ability to estimate TI from cancer registry data would assist with monitoring effects of treatment during survivorship in registry-based epidemiological studies.

Greater Levels of Self-Reported Adherence to Pre-Exposure Prophylaxis (PrEP) are Associated with Increased Condomless Sex Among Men Who Have Sex with Men.

The effectiveness of pre-exposure prophylaxis (PrEP) against HIV acquisition depends on treatment adherence; however, within-person associations between levels of PrEP adherence and engagement in condomless sex have not been well studied. In the context of a demonstration project, 372 men who have sex with men received once-daily PrEP and completed six study visits over 48 weeks. Two-part growth mixture modeling was used to examine the longitudinal trajectory of condomless anal intercourse (CAI) and self-reports of PrEP adherence, controlling for relevant covariates. Over time, greater PrEP adherence was contemporaneously associated with both a higher likelihood of engaging in any CAI and with a greater number of CAI acts. Substance use was also associated with a higher likelihood of engaging in CAI. Contemporaneous associations between self-reported PrEP adherence and CAI suggest that adherence behaviors may be motivated by the desire to mitigate risk of HIV infection; however, exact directionality is unknown.

RESUMEN: La eficacia de la profilaxis Pre-exposición (PrEP) contra la adquisición del VIH depende de la adherencia al tratamiento; sin embargo, las asociaciones dentro de la persona entre los niveles de adherencia a PrEP y la participación en el sexo sin condón no han sido bien estudiadas. En un proyecto de demostración, 372 hombres que tienen relaciones sexuales con hombres recibieron PrEP diariamente y completaron seis visitas de estudio durante 48 semanas. El modelado de mezclas de crecimiento en dos partes se utilizó para examinar la trayectoria longitudinal de las relaciones sexuales anales sin condonación (CAI) y los autoinformes de adherencia a PrEP, controlando las covariables pertinentes. Con el tiempo, una mayor adherencia a PrEP se asoció a la misma vez con una mayor probabilidad de participar en cualquier CAI y tambien con un mayor número de CAI. El consumo de sustancias también se asoció con una mayor probabilidad de participar en CAI. Las asociaciones contemporáneas entre la adherencia a PrEP autoinformada y CAI sugieren que los comportamientos de adherencia pueden estar motivados por el deseo de mitigar el riesgo de infección por el VIH; sin embargo, se desconoce la direccionalidad exacta.

Childhood Cancer Survivorship and Substance Use Behaviors: A Matched Case-Control Study Among Hispanic Adolescents and Young Adults.

PURPOSE: This case-control study compared substance use behaviors between Hispanic adolescent and young adult survivors of childhood cancers (cases) and a community sample of participants without cancer (controls). METHODS: A total of 100 cases were matched to controls (200 participants) one to one by ethnicity, age, and sex (mean age at survey 19.27, standard deviation = 1.92). Differences in self-reported previous 30-day use of tobacco, alcohol, binge drinking of alcohol, and marijuana were examined using conditional multivariable logistic regression. RESULTS: The odds of tobacco, alcohol, binge drinking, and marijuana use were significantly lower for cases than for controls (all p's <.05). When stratified by age, cases (vs. controls) under 21 years of age reported lower levels of substance use (all p's <.05), whereas differences over the age of 21 were nonsignificant. CONCLUSIONS: Lower levels of substance use among Hispanic adolescent and young adult survivors of childhood cancers (vs. controls) are most apparent at younger ages. Future work needs to examine a potential delay in initiation of use among survivors.

Acculturation, Mental Health, and Quality of Life among Hispanic Childhood Cancer Survivors: A Latent Class Analysis.

Objective: Acculturation appears to be an important aspect of the association between ethnicity and disease, but it has not been explored in depth among childhood cancer survivors (CCS). The purpose of our study was to identify distinct acculturative profiles among Hispanic CCS and to assess differences in quality of life and depressive symptoms. Design: Latent class analysis was used to identify distinct acculturative profiles using 9 indicator items reflecting Hispanic and Anglo cultural orientation. Multinomial logistic regression was performed to explore differences in depressive symptoms and quality of life between acculturation classes. Setting and Participants: Participants were diagnosed in Los Angeles County, California, USA between 2000-2007 and were recruited for the study in 2009. Main Outcome Measures: Center for Epidemiologic Studies depression scale and the PedsQL 4.0 quality of life scale. Results: Three distinct acculturation classes emerged. All classes displayed a high probability of endorsing all Anglo orientation items. One class additionally demonstrated a high probability of endorsing all Hispanic orientation items and was labeled bicultural 40%); another demonstrated low probability of endorsing the Hispanic items so was labeled assimilated (32%); and the last demonstrated a high probability of endorsing only the Hispanic items related to language use and was labeled linguistically Hispanic/culturally Anglo (LH) (28%). Conclusions: The assimilated group had significantly more depressive symptoms and lower quality of life than the other two groups. This may indicate that loss of the Hispanic culture may be associated with poorer psychosocial health among CCS.

Posttraumatic growth among childhood cancer survivors: Associations with ethnicity, acculturation, and religious service attendance.

This study assessed the association between ethnicity, religious service attendance (RSA), and acculturation with posttraumatic growth (PTG) in a diverse sample of 235 childhood cancer survivors (CCS). PTG scores were estimated for each ethnicity, and by level of RSA and acculturation. There was a significant curvilinear relationship (inverted U) between RSA and PTG, such that moderate levels of RSA were associated with the highest PTG scores. Hispanics reported the highest PTG, and both Hispanic and Anglo cultural orientation were significantly positively associated with PTG. CCS with high or low frequency of RSA as well as Hispanic CCS who lack a strong sense of cultural identity may benefit from targeted efforts to promote psychosocial adaptation in the aftermath of cancer.

Intrauterine Device Use and Cervical Cancer Risk: A Systematic Review and Meta-analysis.

OBJECTIVE: To estimate the association between use of an intrauterine device (IUD) and risk of cervical cancer by subjecting existing data to critical review, quantitative synthesis, and interpretation. DATA SOURCES: We searched PubMed, Web of Science, ClinicalTrials.gov, and catalogs of scientific meetings and abstracts, theses, and dissertations queried from inception through July 2016. METHODS OF STUDY SELECTION: Examination of abstracts from 225 reports identified 34 studies with individual-level measures of use of an IUD and incident cervical cancer. By critically assessing the full text of these reports, independent reviewers identified 17 studies conducted without recognized sources of systematic error, of which 16 could be harmonized for meta-analysis. TABULATION, INTEGRATION, AND RESULTS: Point and interval estimates of the association between use of an IUD and incident cervical cancer were extracted from original reports into a structured database along with key features of study design and implementation. A random-effects meta-analysis was implemented to quantitatively synthesize extracted estimates and assess likely influence of publication bias, residual confounding, heterogeneity of true effect size, and human papillomavirus prevalence and cervical cancer incidence in source populations. Women who used an IUD experienced less cervical cancer (summary odds ratio 0.64, 95% CI 0.53-0.77). Neither confounding by recognized risk factors nor publication bias seems a plausible explanation for the apparent protective effect, which may be stronger in populations with higher cervical cancer incidence. CONCLUSION: Invasive cervical cancer may be approximately one third less frequent in women who have used an IUD. This possible noncontraceptive benefit could be most beneficial in populations with severely limited access to screening and concomitantly high cervical cancer incidence.
