Feasibility of a Health Coach Intervention to Reduce Sitting Time and Improve Physical Functioning Among Breast Cancer Survivors: Pilot Intervention Study. JMIR Cancer 2023; 9:e49934. [PMID: 38113082 PMCID: PMC10762618 DOI: 10.2196/49934] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 11/16/2023] [Accepted: 11/23/2023] [Indexed: 12/21/2023] Open
Abstract
BACKGROUND Sedentary behavior among breast cancer survivors is associated with increased risk of poor physical function and worse quality of life. While moderate to vigorous physical activity can improve outcomes for cancer survivors, many are unable to engage in that intensity of physical activity. Decreasing sitting time may be a more feasible behavioral target to potentially mitigate the impact of cancer and its treatments. OBJECTIVE The purpose of this study was to investigate the feasibility and preliminary impact of an intervention to reduce sitting time on changes to physical function and quality of life in breast cancer survivors, from baseline to a 3-month follow-up. METHODS Female breast cancer survivors with self-reported difficulties with physical function received one-on-one, in-person personalized health coaching sessions aimed at reducing sitting time. At baseline and follow-up, participants wore the activPAL (thigh-worn accelerometer; PAL Technologies) for 3 months and completed physical function tests (4-Meter Walk Test, Timed Up and Go, and 30-Second Chair Stand) and Patient-Reported Outcomes Measurement Information System (PROMIS) self-reported outcomes. Changes in physical function and sedentary behavior outcomes were assessed by linear mixed models. RESULTS On average, participants (n=20) were aged 64.5 (SD 9.4) years; had a BMI of 30.4 (SD 4.5) kg/m2; and identified as Black or African American (n=3, 15%), Hispanic or Latina (n=4, 20%), and non-Hispanic White (n=14, 55%). Average time since diagnosis was 5.8 (SD 2.2) years with participants receiving chemotherapy (n=8, 40%), radiotherapy (n=18, 90%), or endocrine therapy (n=17, 85%). The intervention led to significant reductions in sitting time: activPAL average daily sitting time decreased from 645.7 (SD 72.4) to 532.7 (SD 142.1; β=-112.9; P=.001) minutes and average daily long sitting bouts (bout length ≥20 min) decreased from 468.3 (SD 94.9) to 366.9 (SD 150.4; β=-101.4; P=.002) minutes. All physical function tests had significant improvements: on average, 4-Meter Walk Test performance decreased from 4.23 (SD 0.95) to 3.61 (SD 2.53; β=-.63; P=.002) seconds, Timed Up and Go performance decreased from 10.30 (SD 3.32) to 8.84 (SD 1.58; β=-1.46; P=.003) seconds, and 30-Second Chair Stand performance increased from 9.75 (SD 2.81) to 13.20 completions (SD 2.53; β=3.45; P<.001). PROMIS self-reported physical function score improved from 44.59 (SD 4.40) to 47.12 (SD 5.68; β=2.53; P=.05) and average fatigue decreased from 52.51 (SD 10.38) to 47.73 (SD 8.43; β=-4.78; P=.02). CONCLUSIONS This 3-month pilot study suggests that decreasing time spent sitting may be helpful for breast cancer survivors experiencing difficulties with physical function and fatigue. Reducing sitting time is a novel and potentially more feasible approach to improving health and quality of life in cancer survivors.

Jesús OJ, Luis CP, Matilde MF. Effects of exercise on cancer-related cognitive impairment in breast cancer survivors: a scoping review. Breast Cancer 2023; 30:885-909. [PMID: 37480454 PMCID: PMC10587261 DOI: 10.1007/s12282-023-01484-z] [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: 12/27/2022] [Accepted: 07/09/2023] [Indexed: 07/24/2023]
Abstract
BACKGROUND Cancer-related cognitive impairment (CRCI) is one of the major long-term concerns reported by breast cancer survivors after overcoming the disease. The present study undertakes a scoping review of relevant research publications to explore the effect of increasing physical activity (PA) levels or the use of exercise (EX)-based programs on CRCI in female breast cancer survivors; who have completed neo/adjuvant chemotherapy treatment and are awaiting or receiving hormonal therapy. METHODS An electronic search of Pubmed, Embase, Scopus, WOS, and Cochrane databases has been conducted to identify published literature from January 2000 to December 2021. RESULTS Of 1129 articles, twenty met the inclusion criteria. The majority of the included observational studies (90%) reported cross-sectional design; meanwhile, 72% of experimental research reported randomized controlled trials (RCTs) or randomized crossover trials. 15 neuropsychological batteries and tests, and 5 self-reported validated questionnaires were employed. Only 27% of the included articles used a combination of the previously mentioned methods. The recorder of moderate-vigorous PA (MVPA), defined as more than 3 METs, or represented as average daily minutes spent (≥ 1952 counts/min) was the most analyzed variable in cross-sectional studies, and EX programs based on aerobic training (AT) were the most proposed by RCTs. CONCLUSIONS The exploratory approach of this review demonstrates modest but increasingly promising evidence regarding exercise's potential to improve brain health among breast cancer survivors although these findings highlight the importance of addressing methodological heterogeneity in the same direction with the view of using exercise within the clinic area.

Breast cancer and occupation: Non-parametric and parametric net survival analyses among Swiss women (1990-2014). Front Public Health 2023; 11:1129708. [PMID: 37089493 PMCID: PMC10115164 DOI: 10.3389/fpubh.2023.1129708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Accepted: 03/14/2023] [Indexed: 04/08/2023] Open
Abstract
Introduction Occupation can contribute to differences in risk and stage at diagnosis of breast cancer. This study aimed at determining whether occupation, along with skill level and the socio-professional category, affect the breast cancer survival (BCS) up to 10 years after diagnosis. Materials and methods We used cancer registry records to identify women diagnosed with primary invasive breast cancer in western Switzerland over the period 1990-2014 and matched them with the Swiss National Cohort. The effect of work-related variables on BCS was assessed using non-parametric and parametric net survival methods. Results Study sample included 8,678 women. In the non-parametric analysis, we observed a statistically significant effect of all work-related variables on BCS. Women in elementary occupations, with low skill level, and in paid employment not classified elsewhere, had the lowest BCS, while professionals, those with the highest skill level and belonging to top management and independent profession category had the highest BCS. The parametric analysis confirmed this pattern. Considering elementary occupations as reference, all occupations but Craft and related trades had a hazard ratio (HR) below 1. Among professionals, technicians and associate professionals, and clerks, the protective effect of occupation was statistically significant and remained unchanged after adjustment for age, calendar period, registry, nationality, and histological type. After adjusting for tumor stage, the HRs increased only slightly, though turned non-significant. The same effect was observed in top management and independent professions and supervisors, low level management and skilled laborers, compared to unskilled employees. Conclusion These results suggest that work-related factors may affect BCS. Yet, this study was conducted using a limited set of covariates and a relatively small study sample. Therefore, further larger studies are needed for more detailed analyses of at risk occupations and working conditions and assessing the potential interaction between work-related variables and tumor stage.
