Study Overview
Brief Summary
Interventions to promote physical activity among women breast cancer survivors (BCS) in low to middle-income countries are limited. We conducted a study to assess the acceptability and preliminary effectiveness of an 8-week, 3 times/week group dance intervention for BCS delivered in Bogotá, Colombia. The effect of the intervention on participants' physical activity levels, motivation to engage in physical activity, and quality of life were evaluated, and interviews were thematically analyzed to assess program acceptability.
Detailed Description
This is a quasi-experimental study with a control group and an intervention group.
The study population are patients over 18 years of age with a diagnosis of breast cancer who have received management and are currently in remission phase (more than 1 year after finishing management with chemotherapy and radiotherapy) and who do not report having any medical contraindication for the practice of physical activity (angina, acute myocardial infarction, pulmonary embolism, arterial hypertension and uncontrolled diabetes mellitus, severe lymphedema). The control group will be patients who attend their medical check-ups at the National Cancer Institute of Colombia and the intervention group will be patients who are cared for by units of the Bogotá's medical service. It will have the written approval of the ethics committee of the respective hospitals.
Being an exploratory study that investigates the acceptability and main motivations for attending physical activity sessions on a regular basis, it is considered that a sample of 30 people in the control group and 30 people in the intervention group could provide the necessary information to have in mind to develop studies with more significant sample sizes in the future.
For 8 weeks the intervention group will be offered 24 classes of musicalized directed physical activity (through a training protocol adapted for patients with this underlying pathology), and 8 craft workshops, to be held in the same space as the physical activity sessions. Additionally, at the same time, healthy habits will be promoted with the control group through text messages during 8 weeks, with a two workshops (at the beginning and the end of this period). The classes and workshops will be held at the facilities of the health provider institution in a place that guarantees the privacy of the participants.
For the recruitment of patients in the intervention group, women who were diagnosed with altered BI-RADS will be contacted by telephone. For the recruitment of patients from the control group, the head nurse who coordinates the follow-up program for breast cancer patients will be asked to invite the women in the study to participate. Additionally, all invited patients will receive the information through an attached information sheet.

Outcomes
Primary Outcomes
Change in participants' quality of life
Time Frame: Quality of life was assessed at baseline and after the 8th week
To assess the change of quality of life, we used the official Colombian Spanish translation of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. It incorporates five functioning subscales, three symptom subscales, six single symptoms, an item for illness-related financial difficulties, and a two-item general health/global QoL subscale. Each item was reported on a 4-point scale ranging from 1 (not at all) to 4 (very much), except for the general health subscale, which response options range from 1 (very poor) to 7 (excellent). High scores on the functioning subscales and the global health status/QoL subscale represent higher quality of life, while high scores on the symptom subscales indicate high levels of symptomatology. We also used a subscale of the EORTC questionnaire specific to breast cancer patients regarding physical symptoms for lymphedema; it comprises seven items with responses also ranging from 1 (not at all) to 4 (very much).
Acceptability of My Body
Time Frame: Semi-structured interviews were conducted after the 8th week
We used a semi-structured interviewing technique to ensure in-depth insights about BCS' perspectives towards physical activity, their anticipated and actual experienced barriers and facilitators to engage in the physical activity intervention, their expected and reported benefits from the physical activity intervention, and the perceived positive and negative aspects of the program.
Change in participants' motivation to engage in physical activity
Time Frame: Motivational regulation for physical activity was assessed at baseline and after the 8th week
To assess the change from baseline participants´ motivational regulation for physical activity at 8 weeks, we used the validated Spanish version of the Behavioral Regulation in Exercise Questionnaire-3 \[BREQ-3\], a 23-item inventory assessing the Self-Determination Theory relevant constructs (which conceptualizes motivation as a continuum ranging from amotivation to a high level of intrinsic motivation). Responses to each item were reported on a 5-point scale ranging from 0 (not true for me) to 4 (very true for me).
Change in participants' physical activity levels
Time Frame: Physical activity levels were assessed at baseline and after the 8th week
To assess the change from baseline participants' physical activity levels at 8 weeks, participants wore accelerometers for 7 consecutive days from awakening to bedtime using an elasticized belt around the waist at the right mid-axillary line. For wear-time validation, a minimum of four weekdays and a weekend day with at least 10 hours of wear during the waking time was required. Accelerometers were initialized to collect data at a sampling frequency of 80 Hz, downloaded in one-second epochs and grouped in 60-second epochs for analysis.
Secondary Outcomes
- Body mass index(BMI was assessed at the baseline)
- Sociodemographic variables(Surveys were collected at the baseline)
