Abstract
Background—Limited data exist on the benefits of, barriers to, and potential strategies to
break up time spent sitting in cancer survivors. Such data will be meaningful given the
consequences of prolonged sitting.
Objectives—To conduct a mixed method research study consisting of semi-structured
telephone interviews to identify recurrent themes associated with prolonged sitting in cancer
survivors.
Author Manuscript
Methods—African American breast cancer survivors (N = 31) were recruited from a local
tumor registry. Telephone interviews were conducted and group consensus processes were used to
identify recurrent themes. The a priori categories were benefits, barriers, and potential strategies to
breaking up prolonged periods of sitting.
Results—Recurrent themes contributing most to prolonged sitting were leisure time interest
(45%: e.g., watching television and reading) and health challenges (27%: e.g., pain and fatigue).
Most (66%) women perceived improved health as benefits to breaking up time spent sitting.
Nonetheless, many (41%) survivors reported health (e.g., pain and fatigue) as the biggest
challenge to breaking up time spent sitting. Engaging in light intensity activities (e.g., staying
active, keep moving) was the most commonly reported strategy for breaking up prolonged sitting.
Conclusions—African American breast cancer survivors identified the benefits and barriers
to breaking up time spent sitting as well as potential strategies to breaking up time-spent sitting.
Author Manuscript
Implications for practice—Clinicians are integral in promoting breaks from prolonged
sitting throughout the initial phases of the cancer continuum. Successful studies will begin with
early intervention in the clinical setting, following with interventions during the recovery phase.

INTRODUCTION
Time spent sitting has emerged as a major risk factor for chronic disease. Prolonged periods
of sitting have been associated with an increased risk for developing colorectal, endometrial,
and ovarian cancer.1 Among cancer survivors, studies have found that prolonged sitting was
associated with diminished quality of life,2 weight gain,3 larger waist circumference,4
ischemic heart disease,5 and premature mortality.6 In a recent study of breast cancer
survivors, George et al.,7 found that survivors spent approximately 10.7 hours per day
sitting, 3 hours more than observed in national data.8 Similarly, recent studies indicate that
cancer survivors were more sedentary during waking hours than age-matched controls.9–11

Importantly, breaking up prolonged sitting may help to attenuate its adverse effects.12, 13
Breaks from sitting have been shown to improve metabolic and cardiovascular risk factors,
even after adjusting for total time spent sitting and physical activity.12–14 Despite the
potential significance of breaking up prolonged sitting, few studies have been developed and
most of the preliminary data on breaking up prolonged sitting have been epidemiological in
nature. In addition, prior studies have focused primarily on healthy samples. Therefore, there
is a need to extend this avenue of research to minority populations (i.e., those with chronic
and debilitating health conditions). Minority populations may experience the greatest
benefits from breaking up prolonged periods of sitting.
Author Manuscript
Cancer survivors have high rates of metabolic disorders and cardiovascular disease15 and are
a high priority group. Given that cancer survivors experience unique challenges that
contribute to prolonged sitting, this group is a unique population to study. Studies that
propose to understand the mechanisms related to prolonged sitting in cancer survivors may
help to create a dialogue in the field of cancer survivorship. Identifying the beliefs and
perceptions about prolonged sitting would be a necessary first step (i.e., formative research)
to designing interventions for cancer survivors that can be used to introduce breaks or
interrupt prolonged sitting throughout the day.
Author Manuscript
Developing a better understanding of perceptions of and benefits related to breaking up
prolonged sitting will provide a better understanding of the causes and conditions that
contribute to prolonged sitting in cancer survivors. African American breast cancer survivors
represent an important group to study the consequences of prolonged sitting. A number of
studies have indicated that they have greater rates of overweight and obesity,16–18 lower
compliance rates for physical activity,16, 19 and higher rates of comorbidities than women of
other racial and ethnic groups.20 In addition, because of having multiple risk factors and
cancers simultaneously, this population is at an elevated risk for cardiovascular injury,21
much more so that women of other racial and ethnic groups.
Further, African American breast cancer survivors may live in urban environments with
higher residential turnover, limited access to facilities for physical activity, unsafe
neighborhoods, and other living conditions that pose particular challenges to an active
lifestyle.22, 23 Understanding the perceptions of prolonged sitting in African American
breast cancer survivors may help to understand the unique opportunities and potential

challenges that will need to be considered prior to developing interventions to reduce
prolonged sitting.
METHODS
Author Manuscript
The purpose of this qualitative study was to identify beliefs, perceptions, and recurrent
themes associated with breaking up prolonged periods of sitting. The data collected in this
study addressed: (1) the factors that influence prolonged sitting, (2) the benefits of, and
barriers to breaking up prolonged sitting, and (3) potential strategies that can be adopted to
break up prolonged sitting. The Consolidated Criteria for Reporting Qualitative Research
(COREQ) checklist was used as the guiding framework for our study. The COREQ
constitutes a set of criteria that were designed to improve the quality of reporting of
qualitative studies.24 The methods and results of this study are presented using the three
domains of the COREQ checklist.24 All study participants were consented prior to
conducting the actual interview. The study was approved by the Institutional Review Board
of a large cancer center prior to conducting the interviews.
Study Population
Author Manuscript
African American breast cancer survivors who received treatment at a large cancer center in
Texas served as the participant pool. Inclusion criteria included being: (1) at least 18 years
and older at the time of diagnosis, (2) diagnosed with Stage I– IV breast cancer between
2002 and 2010, (3) currently residing in Houston, Texas or the surrounding metropolitan
area, and (4) having up-to-date contact information in the tumor registry. Data collection was
completed using telephone interviews. A total of 31 out of 91 telephone calls resulted in
actual interviews. The remainder of telephone calls ended in non-returned messages (n =
30), wrong numbers (n = 16), no messages (n = 7), no interest in participating (n = 6), and
an ineligible survivor (n = 1).
Procedures
Author Manuscript
In this study, qualitative telephone interviews were conducted to solicit the perceptions and
beliefs of breaking up prolonged sitting in a sample of African American breast cancer
survivors. The semi-structured telephone interviews occurred during the day, between
February 5th and March 5th of 2013. Each interview lasted approximately 10 to 15 minutes.
The interviews followed a script, consisting of: 1) an introduction of the interviewer; 2) an
introduction to the study; 3) information on breaking up sitting (definition and health
outcomes) and a series of open-ended questions to elicit information on attitudes toward
sitting (perceived benefits and challenges) and sitting habits. We identified a priori, four
general categories around the topic of time spent sitting, which included: (a) contributing
factors, (b) barriers to, (c) benefits of, and (d) strategies to reduce prolonged sitting.
Researchers took notes during and after the interview to ensure that all relevant content was
recorded. In the event that the interviewer did not hear or understand the participant, the
participant was asked to clarify her response.

Characteristics of the Telephone Interviewers
Author Manuscript
The study was conducted by two male professors and two female graduate students. At the
time of the study, the students were working toward a Master of Public Health degree and a
Doctoral degree in Public Health. The survivors had no prior knowledge of or interaction
with any of the interviewers. At the beginning of the interview, the interviewer introduced
her/himself as a researcher from an academic institution and survivors were informed about
the goals of the study. Following this introduction, the researcher asked a series of openended questions. The specific questions asked during the telephone interviews are reported
in the results section verbatim. Participants were allowed to provide multiple answers to
each question. All responses were recorded. Below is the framework for this portion of the
conversation:
Author Manuscript
•
How much time do you spend sitting while… (driving/riding in a car, watching
television or videos, talking on the telephone, talking with friends, listening to
music, reading, playing video games, or using a computer/Internet for leisure)?
•
What are your perceptions and beliefs about prolonged sitting?
Measures
Author Manuscript
Leisure-time sedentary behavior—Sedentary behavior was measured using a 7-item
modified version of the Sedentary Behavior Questionnaire (SBQ).25 The SBQ has
demonstrated adequate reliability and validity.25 The behaviors were identified on the basis
of time-use studies in Australia and metabolic equivalent values of 1.0 to ≤1.5 METS (i.e.,
sitting, reclining, lying down while awake).26, 27 The survey was administered over the
phone and participants were asked “on how many days did you do the activity in the past 7
days, and on average, how many minutes did you do the activity on the days that you did it?”
Sedentary behaviors included sitting while: driving/riding in a car, watching television or
videos, talking on the telephone, talking with friends, listening to music, reading, playing
video games, or using a computer/Internet for leisure. Sedentary behavior items were based
on activities performed before or after work, not during work. Similar sedentary behaviors
were assessed in a previous study.28 For the purposes of this study, estimates represented
average daily minutes spent in each sedentary behavior.
Sociodemographic and medical characteristics were extracted from the tumor registry. The
specific information used for this study included current age, age at cancer diagnosis, and
disease stage at diagnosis. Years out from diagnosis were computed from the differences
between ages. Employment status was ascertained during the interview process.

Mixed method data analysis
To ensure that the interviews were conducted consistently and accurate data were obtained,
the analysts (RJP, AA, and SS) received training from the senior faculty member (WCT)
who was experienced in qualitative research methods. The research team used a consensus
process guided by a specific protocol for qualitative content data analysis.24, 29 This process
consisted of entering the transcribed notes into an Excel spreadsheet for further coding and
abstracting. In the event that one or more members of the team did not understand the
participants’ response, an iterative process was used to clarify the statement in the context of

the study protocol. The two faculty (RJP and WCT) members were responsible for
identifying and categorizing notes into emerging themes. Once the themes were identified,
each team member was responsible for determining whether they agreed or disagreed with
the coding of each individual theme. When consensus could not be reached regarding the
coding of a statement, the data were recoded (or theme renamed) until 100% agreement was
achieved. Recurrent themes that captured the essence of participants’ ideas were retained,
whereas ambiguous themes were categorized as other. The researchers allowed for multiple
responses to a single question. After the themes were confirmed, we transferred the data to
SPSS, where the frequency for each theme could be computed to determine its relevance.
RESULTS
Descriptive Characteristics of Sample
Author Manuscript
Survivors were between the ages of 22 to 75 years old at the time of the interview and had a
mean of 4.2 years out from diagnosis. Most survivors were diagnosed with localized or
regional stage disease and were unemployed at the time of the interview. Survivors reported
sitting on average 430 minutes (7.2 hours) per day while at home. Survivors spent the most
time sitting more while watching television, talking on phone, riding/driving in a car, and
while reading (See Table 1).
What would you say are the factors that contribute most to the amount of time you
spend sitting?
Author Manuscript
A total of 5 themes were identified as factors associated with sitting. The recurrent themes
included leisure activities (45%), health challenges (27%), personal habits (12%), household
responsibilities (10%), and social activities (6%). The most commonly reported themes
associated with sitting were watching television, pain, and fatigue, laying down to relax,
paying bills, and talking on the phone (Table 2). Examples include:
Author Manuscript
•
Leisure activities: “Older people take a longer time on the Internet;” “I spend
too much time watching television;” “I like to sit and read.”
•
Health challenges: “When I move too much, my joints get stiff;” “I usually get
tired;” “I need to rest a little more.”
•
Personal habits: “ I usually sit down to eat dinner;” “Sitting down to do
homework with my son;” “I have a long commute to and from work.”
•
Household responsibilities: “I sit when I read my bills;” “managing finances;”
“I sit when I’m taking care of business.”
•
Social activities: “Talking;” “Being on the phone;” “Sitting with grandkids.”
What do you think are some of the benefits to breaking up or interrupting prolonged
sitting?
Three themes were identified, which related to the benefits of breaking up prolonged sitting.
Survivors reported health benefits (66%) and health problems (problem avoidance, 16%)
that can be avoided if time spent sitting was reduced. Common health benefits of breaking
up prolonged sitting were gaining more energy, and improvement in weight and memory.

Additional benefits reported by survivors were classified as other (17%). Examples are
below:
•
Health benefits: “It’s good to be active;” “It’s good for the heart;” “I will be
able to breathe better.”
•
Avoidance of health problems: “If I stand more, I’ll have fewer blood clots;”
“My hands and knees will be less stiff;” “It will stop the numbness in my legs.”
•
Other: “I’ll be able to finish what I get started,” “Be able to get a little
exercise;” “I can find things to do.” “Getting things done around the house.”
What are challenges that prevent you from breaking up or interrupting prolonged
periods of sitting? For example, some survivors have indicated that they were too tired
Author Manuscript
Four themes were identified related to the challenges of breaking up time spent sitting. The
majority reported health challenges (41%) as a barrier to breaking up prolonged sitting,
followed by challenges with emotional well-being (23%). Other challenges reported were
related to time constraints (16%) and a combination of other challenges (20%). Examples
are provided below:
Author Manuscript
•
Health challenges: “I could not get up. I had knee and back surgery;” “I just
don’t feel well all the time;” “The dialysis makes me tired.”
•
Emotional well-being: “Sometimes I’m stressed and need to lay down;” “I’m
just lazy;” “My personality has changed.”
•
Time constraints: “Being a wife and a parent, I don’t have a lot of time for
myself;” “The bills have to be paid;” “I’m constantly going to the doctor. I just
don’t have the time.”
•
Other: “Once you form a habit, it’s hard to change;” “I don’t have an active
life;” “Sometimes I need to just get off my feet.”
What are potential strategies that you can use to break up or interrupt prolonged periods
of sitting?
Potential strategies reported by survivors to reduce time spent sitting included engaging in
leisure and recreational activities (54%), household chores (33%), and activities classified as
other (13%). Examples include:
Author Manuscript
•
Recreational activities: “Going for a walk;” “Moving around the house;” “Do
some exercises.” “I could decorate.”
•
Household chores: “I can rake up leaves;” I could always do more chores;”
“Washing clothes.”
•
Other: “I can do things for others;” “I could try to make myself expendable;”
“When I don’t have to sit, I won’t sit.”

DISCUSSION
Author Manuscript
This study presented a unique opportunity to explore the behavioral habits and beliefs of
minority cancer survivors. African American breast cancer survivors were targeted for this
study because of their high vulnerability to health risk factors and complications compared
to other breast cancer survivors.16, 18 Our data suggest that African American breast cancer
survivors, especially those who are currently employed are sitting more that the general
population8 and more than other populations of cancer survivors.17 Differences between the
amount of time spent sitting reported by our women and those observed in other studies
could be due to the fact that we used a self-report instrument, rather than accelerometers to
capture these data. Often, individuals are not cognizant of the amount of time that they
spend sitting. In fact, highly active individuals can also engage in prolonged sitting (e.g.,
active couch potatoes). The use of accelerometers may help to account for the reporting
biases associated with self-report instruments. Despite these methodological differences, our
data paint a grim picture for this population, and suggest that African American breast
cancer survivors are in need of studies to help them transition gradually from prolonged
periods of sitting to incorporating brief segments of light intensity physical activities. A
gradual transition from prolonged sitting to such activities may help to shield African
American breast cancer survivors from the adverse consequences of prolonged
sitting.3, 6, 30–3216, 20

In this study, we collected quantitative data on the sedentary habits of African American
breast cancer survivors and qualitative data to identify their perceptions, beliefs, and
recurrent themes related prolonged sitting. Our data indicates that African American breast
cancer survivors were sitting approximately 7.1 hour per day during their leisure time and an
additional 5 hours per day if they were employed. Despite the habitual nature of their
sedentariness, survivors readily described the pros and cons of breaking up prolonged
sitting. Many of the beliefs were centered on health benefits and health challenges that they
experienced. Encouragingly, survivors expressed the need to engage in light intensity
activities during their leisure and recreational times to break up prolonged periods of sitting.
Overall, these data suggest that survivors were aware of the unhealthy consequences of
prolonged sitting as well as potential strategies to adopt to reduce prolonged sitting
throughout the day.
Leisure choice practices such as watching television and reading contribute to prolonged
sitting. Sitting while watching television is problematic for all and may facilitate further
adverse complications for African American breast cancer survivors. Prior studies have
indicated that sitting, while watching television is associated with consuming high fat, high
sugar, and energy dense foods.33 Although, we did not assess snacking behaviors in this
study, the combination of sitting and snacking may be the culprit behind excess weight gains
that African American breast cancer survivors experience following cancer treatment. Sitting
and watching television appears to be relaxing for this population and may provide an
opportunity for survivors to unwind after a stressful day. Although these behaviors may
appear to be relaxing, they elevate the risk for obesity and premature mortality for many
cancer survivors.1, 3, 6

Of interest was the emphasis placed on pain and fatigue as factors that contributed most to
prolonged sitting. Previous studies examining the relationship between time-spent sitting
and patient-reported outcomes have been decidedly mixed.31, 34, 35 For example, two recent
studies30, 31 observed no association between time spent sitting and patient reported
outcomes in cross-sectional or longitudinal analysis. In another recent study,7 objectively
measured sitting was associated with physical function and general health, but not pain or
fatigue (or vitality). Here, survivors perceived that breaking up sitting would improve
physical and mental well-being as well as prevent pain and stiffness in joints. Thus, pain and
fatigue may be antecedents of prolonged sitting and lower levels of pain and fatigue may be
a consequence of reducing prolonged sitting. The reciprocal nature between behavior and
psychological/physiological states have been proposed in the Social Cognitive Theory36 may
apply here. Education about the hazards are prolonged sitting should be discussed during the
treatment phase of the cancer control continuum because cancer-related fatigue and pain
may contribute to declines in cardiorespiratory fitness and functional status.37 Declines in
fitness may exacerbate prolonged periods of sitting throughout the treatment and recovery
phases of the cancer continuum. These habits may ultimately contribute to enjoying
sedentary hobbies and results in further functional decline over time as survivors proceed
through the distal phases of the cancer continuum. This hypothesis is supported by prior
studies, which indicate that lower levels of physical activity and physical functioning and
higher levels of sedentary behavior among African American breast cancer survivors when
compared to other racial and ethnic groups of cancer survivors.16, 17

Health challenges were perceived as the greatest barriers to breaking up time spent sitting.
Although survivors perceived that breaking up sitting would relieve pain and fatigue, these
were also the greatest barriers to breaking up time-spent sitting. Practitioners and researchers
should consider encouraging survivors to weigh the pros and cons to breaking up time-spent
sitting. Decisional balance sheets (i.e., weighing the pros and cons)38 have been effective in
physical activity research and may help cancer survivors see the tangible benefits of
breaking up the time they spend sitting throughout the day. Stress-related components were
also prevalent in this population. Many women reported that ‘just being too lazy’ or ‘feeling
mentally whipped’ were barriers to breaking up time spent sitting. We are not sure whether
feeling mentally whipped or lazy were components of fatigue or whether these comments
represented the daily life stressors of African American breast cancer survivors.
Author Manuscript
Survivors were queried about possible strategies that they could adopt to break up the time
they spent sitting. Surprisingly, survivors recommended light intensity leisure and
recreational activities around the home as possible strategies to break up prolonged sitting.
These activities included ‘staying active’ and doing chores. One potential strategy that
survivors could adopt would be to incorporate chores while watching television or during
commercial breaks.39 Being active during commercials could help survivors minimize the
amount of high-fats foods that men and women consume unconsciously while watching
television.40 Similarly, survivors may benefit from standing periodically while reading their
mail or books.39

Implications for Practice
Author Manuscript
Practitioners should recommend that survivors break up prolonged periods of sitting by
reallocating time from sedentary activities into light-intensity physical activity.41 Lightintensity physical activity has been associated with improved body mass index42 and
functional status.43–45 Additionally, breaking up sitting may be more acceptable and feasible
than promoting moderate-to-vigorous physical activity in cancer survivors.32, 46 Prior studies
have advocated for strategies such as walking or calisthenics exercises.47, 48 In particular,
calisthenics exercises were associated with greater energy expenditure and heart rate
response when compared to other light-intensity physical activities.47 Also, moving during
television commercials and while talking on the telephone can be easily incorporated into
one’s lifestyle. However, it should be noted that these strategies were implemented in
healthy samples and not cancer survivors. More research is needed to understand what
strategies are viable for cancer survivors to implement during and after treatment.

Strengths and Limitations
Author Manuscript
This study had a number of strengths including being among the first studies to examine
themes associated with breaking up time spent sitting and presenting information on a
underserved population of cancer survivors. In addition, there are a number of strengths
associated with qualitative studies. Primarily, these data were derived from participants’
perceptions of a priori determined categories; this study provides new data on the
antecedents and consequences of behaviors that remain relatively unexplored in the field of
cancer survivorship. Despite these strengths, there are a number of weaknesses that should
be acknowledged. In particular, hand-written notes were taken, which may have introduced
error in interpreting the responses. Further, no comorbidity data or other data that may
characterize the lifestyle habits (i.e., body mass index, physical activity, etc.) of this
population were collected; these data may not be generalizable to other groups of cancer
survivors; also, it is inappropriate to draw causal inferences from our data or test hypotheses.
However, these data provide a basis to better understand perceptions and misperceptions
about interrupting prolonged sitting and all responses were clarified before the telephone call
ended.
Conclusions
Author Manuscript
This study provides data related to benefits, challenges, and potential strategies for
interrupting prolonged sitting among African American breast cancer survivors. It would be
interesting to know to what extent these data are unique to the cultural beliefs of African
American women and to there specific experiences of breast cancer survivors. In the absence
of relevant data from other racial and ethnic groups and other types of cancers, there is an
insufficient basis to speculate. Future research can address whether prolonged sitting is
different for cancer survivors compared to those with other chronic conditions. Also, as
mentioned earlier, among cancer survivors are their racial, ethnic, and cultural differences
related to prolonged sitting? In addition, more research is needed to identify the specific
adverse consequences of prolonged sitting related to quality of life, years of life lost, and
monetary costs.

In summary, this study provides new data about the benefits and barriers of breaking up
prolonged sitting as well as potential strategies that African American breast cancer
survivors can adopt to break up prolonged sitting throughout the day. Navigating the
challenges associated with cancer and its treatment can be a constant struggle for cancer
survivors. If the perceptions of the benefits perceived by cancer survivors are true, breaking
up time spent siting may help survivors gain physical and psychological benefits. Future
studies are needed to ensure that these results can be generalized to other populations of
cancer survivors and expand the study of sedentary behavior in the field of cancer
survivorship.
