Six-Month Outcomes of a Theory- and Technology-Enhanced Physical Activity Intervention for Latina Women (Pasos Hacia La Salud II): Randomized Controlled Trial. J Med Internet Res 2024; 26:e51708. [PMID: 38842930 PMCID: PMC11190618 DOI: 10.2196/51708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 11/10/2023] [Accepted: 03/01/2024] [Indexed: 06/07/2024] Open
Abstract
BACKGROUND More than half (55%) of Latina women do not meet aerobic physical activity (PA) guidelines, and frequently cite time, childcare, and transportation as barriers to PA. In addition to linguistic adaptations for this population, successful PA interventions for Latina women addressed these barriers through remote intervention delivery approaches (eg, mail, phone, or web delivery). OBJECTIVE We aimed to evaluate 6-month outcomes of a randomized trial comparing a Spanish-language, individually tailored, web-delivered PA intervention (original) to an enhanced version with text messages and additional features (enhanced). Further, we evaluated if increases in PA at 6 months were moderated by baseline activity status. METHODS In total, 195 Latina women aged 18-65 years participated in a trial comparing the efficacy of the enhanced versus original interventions at initiating PA behavior change. We examined minutes per week of accelerometer-measured PA in the enhanced versus original arms, and the proportion of each arm meeting aerobic PA guidelines (150 min/wk at 6 mo). For moderator analyses, participants were classified as inactive (0 min/wk) or low active (1-90 min/wk) at baseline, measured via the 7 Day Physical Activity Recall interview. RESULTS PA increased from 19.7 (SD 47.9) minutes per week at baseline to 46.9 (SD 66.2) minutes per week at 6 months in the enhanced arm versus 20.6 (SD 42.7) minutes per week to 42.9 (SD 78.2) minutes per week in the original arm (P=.78). Overall, 30% (31/103) of the enhanced group met aerobic PA guidelines at 6 months, compared to 21% (19/92) of the original group (odds ratio [OR] 1.75, 95% CI 0.87-3.55). Baseline PA (inactive vs low active) moderated treatment effects on PA. For inactive participants, there were no group differences at 6 months (b=7.1; SE 22.8; P=.75), while low-active participants increased more in enhanced than original (b=72.5; SE 27.9; P=.01). For low-active participants, 45% (46/103) of the enhanced group met PA guidelines at 6 months, versus 20% (18/92) of the original arm (OR 3.29, 95% CI 1.05-11.31). For inactive participants, there were no group differences (25/103, 24% vs n=19/92, 21% for enhanced vs original, respectively; OR 1.28, 95% CI 0.54-3.06). CONCLUSIONS Intervention effects were conditional on baseline PA. For low-active Latina women, the enhanced intervention was more effective at increasing PA. Additional tailored intervention enhancements may be necessary to increase PA for inactive Latina women.

Pasos Hacia La Salud II: A Superiority RCT Utilizing Technology to Promote Physical Activity in Latinas. Am J Prev Med 2024:S0749-3797(24)00085-0. [PMID: 38490284 DOI: 10.1016/j.amepre.2024.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 03/07/2024] [Accepted: 03/08/2024] [Indexed: 03/17/2024]
Abstract
INTRODUCTION Latinas face an increased risk for chronic diseases associated with insufficient physical activity (PA). The researchers previously showed that a website-based intervention could increase PA among insufficiently active Latinas, yet rates of meeting national PA guidelines were low. The original intervention was enhanced by adding additional features, content, and points of contact, including via text messaging. This study tests the efficacy of the enhanced intervention compared with the original, aimed at maximizing and sustaining PA gains across 24 months. It also examines if increases in PA differed by baseline PA. STUDY DESIGN The researchers conducted a superiority randomized controlled trial (data collected 2018-2022, analyzed 2023). SETTING/PARTICIPANTS Participants were 195 Spanish-speaking Latinas ages 18-65 in the Providence, RI area. INTERVENTION The original intervention is an empirically supported Spanish-language, individually-tailored, website-delivered PA intervention. The enhanced intervention includes text messaging and additional data-driven content and interactive features. MAIN OUTCOME MEASURES Total weekly minutes of moderate to vigorous PA (MVPA) was measured via accelerometry and self-report at 6, 12, 18, and 24 months. RESULTS Participants in both groups increased their MVPA over 24 months. There were no significant between-group differences at 6 or 12 months; at 18 months the enhanced intervention group had higher levels of self-reported (mean (sd): 90.35 (43.55) vs 70.18 [9.99]) and accelerometer-measured (66.21 [18.26] vs 60.27 [16.00]) MVPA compared to the original intervention group. They also had higher levels of self-reported (111.17 [23.35] vs 81.44 [1.82]) and accelerometer-measured (63.76 [15.12] vs 54.86 [14.59]) MVPA at 24 months. Baseline PA moderated the intervention effect. CONCLUSIONS This study demonstrates the potential to enhance the efficacy of website-based PA interventions by utilizing text messaging, and adding more interactive features, content, and phone support. These enhancements may be particularly beneficial in supporting long-term PA maintenance. TRIAL REGISTRATION This study is registered at www. CLINICALTRIAL gov (NCT03491592).

Stigma and Social Determinants of Health Associated With Fidelity to Guideline-Concordant Therapy in Patients With Breast Cancer Living With and Without HIV in Botswana. Oncologist 2023; 28:e1230-e1238. [PMID: 37405697 PMCID: PMC10712728 DOI: 10.1093/oncolo/oyad183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Accepted: 06/01/2023] [Indexed: 07/06/2023] Open
Abstract
BACKGROUND Patients with breast cancer in sub-Saharan Africa (SSA) experience a disproportionate burden of mortality. Fidelity to treatment guidelines, defined as receiving optimal dose and frequency of prescribed treatments, improves survival. We sought to identify patient factors associated with treatment fidelity and how this may differ for people with HIV (PWH) and breast cancer. METHODS We conducted a qualitative study of women who initiated outpatient treatment for stages I-III breast cancer in Botswana, with deviance sampling of high- and low-fidelity patients. One-on-one interviews were conducted using semi-structured guides informed by the Theory of Planned Behavior. The sample size was determined by thematic saturation. Transcribed interviews were double coded with an integrated analytic approach. RESULTS We enrolled 15 high- and 15 low-fidelity participants from August 25, 2020 to December 15, 2020, including 10 PWH (4 high, 6 low fidelity). Ninety-three percent had stage III disease. Barriers to treatment fidelity included stigma, social determinants of health (SDOH), and health system barriers. Acceptance and de-stigmatization, peer and other social support, increased knowledge and self-efficacy were identified as facilitators. The COVID-19 pandemic amplified existing socioeconomic stressors. Unique barriers and facilitators identified by PWH included intersectional stigma, and HIV and cancer care integration, respectively. CONCLUSION We identified multilevel modifiable patient and health system factors associated with fidelity. The facilitators provide opportunities for leveraging existing strengths within the Botswana context to design implementation strategies to increase treatment fidelity to guideline-concordant breast cancer therapy. However, PWH experienced unique barriers, suggesting that interventions to address fidelity may need to be tailored to specific comorbidities.

Abstract
Pancreatic cancer (PCa) remains a formidable global health challenge, with high mortality rates and limited treatment options. While advancements in pharmacology have led to improved outcomes for various cancers, PCa continues to exhibit significant health disparities, disproportionately affecting certain populations. This paper explores the intersection of pharmacology and anthropology in understanding the health disparities associated with PCa. By considering the socio-cultural, economic, and behavioral factors that influence the development, diagnosis, treatment, and outcomes of PCa, pharmacologic anthropology provides a comprehensive framework to address these disparities and improve patient care.
