Work, travel, or leisure: comparing domain-specific physical activity patterns based on rural-urban location in Canada

BACKGROUND

Physical activity occurs across various domains including leisure/recreation, for transportation, or for work or household reasons. Rural and urban active living environments are characterized by different opportunities for physical activity within each domain which may translate into different patterns of behavior. The aim of this study was to compare rural-urban differences in physical activity across different domains, and explore interactions between sociodemographic factors, physical activity domains, and rurality.

METHODS

We used self-reported data collected across three physical activity domains (active transportation, recreation, occupational/household) and relevant sociodemographic variables from the Canadian Community Health Survey. Adjusting for sociodemographic factors, we did two separate cross-sectional analyses: 1) binary logistic regression to determine the odds of reporting any activity in each domain, and 2) ordinary least squares regression using the sub-samples reporting > 0 min per week of activity to compare how much activity was reported in each domain.

RESULTS

Our final survey weighted sample of Canadian adults (mean age 47.4 years) was n = 25,669,018 (unweighted n = 47,266). Rural residents were less likely to report any active transportation (OR = 0.59, 95% CI [0.51, 0.67], p < .0001). For recreational physical activity, rural males had lower odds (OR = 0.75, 95% CI [0.67, 0.83], p < .0001) and rural females had higher odds (OR = 1.19, 95% CI [1.08, 1.30], p = .0002) of reporting any participation compared to urban residents. Rural males (OR = 1.90, 95% CI [1.74, 2.07], p < .0001) and females (OR = 1.33, 95% CI [1.21, 1.46], p < .0001) had higher odds of reporting any occupational or household physical activity.

CONCLUSIONS

Urban residents tend to participate in more active transportation, while rural residents participate in more occupational or household physical activity. Location-based differences in physical activity are best understood by examining multiple domains and must include appropriate sociodemographic interactions, such as income and sex/gender.

Can In-Task Affect During Interval and Continuous Exercise Predict 12-Month Physical Activity Behavior? Findings from a Randomized Trial

BACKGROUND

In-task affective responses to moderate-intensity continuous exercise training (MICT) have been shown to predict future physical activity behavior. However, limited research has investigated whether this affect-behavior relationship is similar for high-intensity interval training (HIIT) and whether it holds true over the longer term. This study aims to determine (1) if in-task affect during 2 weeks of supervised MICT and HIIT predicted changes to unsupervised moderate-to-vigorous physical activity (MVPA) behavior 12 months post-intervention and (2) if this predictive relationship was moderated by exercise type (MICT vs. HIIT).

METHOD

Ninety-nine adults (69.7% female; 50.9 ± 9.4 years) who were low active and overweight were randomized to 2 weeks of exercise training of MICT (n = 52) or HIIT (n = 47), followed by 12 months of accelerometry-assessed free-living MVPA.

RESULTS

The pooled moderation model was not significant, F(3, 94) = 2.54, p = .07 (R2 = 0.085), with a non-significant group by affect interaction (p = .06). The conditional effect for MICT was significant (B = 17.27, t = 2.17, p = .03), suggesting that 12-month change in MVPA increased by 17.27 min/week for every one-point increase in in-task affect. The conditional effect for HIIT was not significant (p = .85), suggesting that in-task affect was not predictive of 12-month change in MVPA.

CONCLUSION

The current findings raise important questions about whether the affect-behavior relationship may vary depending on exercise type. For HIIT-based exercise in particular, additional psychological constructs beyond in-task affect should be considered when attempting to predict future physical activity behavior.

[Lifestyle-integrated functional exercise for fall prevention : How and why do walking characteristics change?]

BACKGROUND

The lifestyle-integrated functional exercise (LiFE) program has been shown to increase physical activity. It remains unclear, however, how these changes translate into long vs. short walking episodes.

OBJECTIVE

The aim of this work was to investigate changes in short vs. long walking episodes between baseline and 6‑month follow-up and to determine which factors are associated with these changes.

MATERIAL AND METHODS

This was a two-arm randomized noninferiority study with 309 older adults (mean age 78.7 ± 0.3 years; 73.5% female) at risk of falling who exercised either in a group (gLiFE; n = 153) or individually (LiFE; n = 156). Walking episodes were measured using activPAL 4micro sensors: a distinction was made between walking episodes < 10s, < 20s, and > 60 s. Changes in walking episodes between baseline and 6‑month follow-up were analyzed, including calculation of effect sizes (Cohen's d). Determinants of changes in the walking episodes were analyzed using multiple regression.

RESULTS

The walking episodes < 10s and < 20 s showed a significant increase in both intervention groups but not for > 60 s. The overall daily walking duration and average steps per day had an influence on changes in the walking episodes between baseline and 6 months. Parameters of objective and subjective function explained a very small but significant amount of the variance.

CONCLUSION

The LiFE program seems to work on a behavioral rather than on a functional level. By accumulating short walking episodes, large gains in physical activity can potentially be achieved. This can be of health-promoting benefit especially for persons living in institutional settings or for those who are cautious or even anxious to undertake longer walking episodes (e.g., outdoors).

Physical activity counseling received throughout pregnancy and effect on behaviors: a quasi-experimental study

OBJECTIVE

The objective was to examine the frequency of physical activity counseling for pregnant women over the course of their pregnancies and the effect on the women's physical activity behaviors.

METHODS

A quasi-experimental study was conducted in the Maternity Unit of a hospital. Seventy-two pregnant women were randomized into a control or intervention group. Counseling about physical activity was dispensed to the women in the intervention group throughout pregnancy by health professionals who had been sensitized to its importance and the recommendations. The women in the control group received the usual consultation content. The physical activity behavior of the pregnant women in the intervention group who reported receiving physical activity counseling was evaluated. The counseling and physical activity levels were evaluated by Chi2 tests and repeated measures ANOVAs, respectively.

RESULTS

Overall, the women received little counseling in accordance with the recommendations, although the intervention group women received this counseling more frequently (p=0.049). All women in the intervention group who reported received counseling throughout pregnancy limited their decline in physical activity compared to those in the control group. The decline in total physical activity among normal-weight and overweight pregnant women was reduced in the intervention group (respectively, p=0.043 and p=0.044).

CONCLUSION

Our intervention showed the effectiveness of counseling on physical activity behaviors, although the effect was observed at the end of pregnancy. Training and sensitizing for professionals should be strengthened to ensure that counseling in line with the recommendations to maintain or increase physical activity levels throughout pregnancy is provided.

Feasibility and thematic analysis of narrative visualization materials with physical activity monitoring among breast cancer survivors

Background

Breast cancer survivors have a unique risk for negative health outcomes. Engaging in routine physical activity (PA) can reduce these risks. However, PA levels are low among this population. Narrative visualization (NV) is a technique that uses drawings, photographs, and text to contextualize data, which may increase integrated regulation, or motivation related to personal values and identity. A PA intervention targeting breast cancer survivors using an NV strategy may improve PA behavior. The purpose of this study was to determine whether scrapbooking activities could successfully be used as an NV strategy for older (55+) breast cancer survivors.

Methods

Breast cancer survivors were given workbooks, wearable electronic activity monitors, instant cameras, and art supplies including a variety of stickers (e.g., emojis, affirmations). Participants were instructed to use these materials for 7 days. The workbook pages prompted participants to re-draw their daily activity graphs from the wearable’s mobile app, then annotate them with text, photographs, stickers, etc. to reflect what the data meant to them. Hybrid thematic analysis was used to analyze the photographs, drawings, and written content to identify emergent themes. Content analysis was also used to investigate use of stickers and photographs.

Results

Of the 20 consented women (mean age 67 ± 5 years, 45% non-Hispanic white), 3 participants were lost to follow-up or unable to complete the procedures. The NV procedures were successfully utilized by the remaining 17 participants, who collectively used 945 stickers over 7 days, most of which were emojis. Emojis were both positively and negatively valanced. Participants took a mean of 9 photos over 7 days and completed workbook questions regarding current PA and PA goals. Themes within the photos included family, specific locations, everyday objects, religion, and friends. Themes within the written portions of the workbook included family, chores and obligations, health, personal reflection, hobbies, and shopping.

Conclusions

The materials provided allowed breast cancer survivors to successfully use NV techniques to reflect on their PA data and behavior. These techniques show promise for promoting integrated regulation in activity monitoring interventions.

Structured Exercise in Cancer Survivors: Is it Enough for Neural, Mental Health and Well-being?

The purpose of this cross-sectional study was to explore physical activity, depression, fatigue, and quality of life (QOL), and their relationship to brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in cancer survivors enrolled in a structured exercise program. Participants were recruited into two groups: in-treatment (IT), currently receiving chemotherapy and/or radiotherapy, and out of treatment (OT), not undergoing therapy. Participants wore accelerometers for 7 days and completed cardiorespiratory fitness, muscular strength, and depression, fatigue, and QOL assessments. Circulating BDNF and NGF concentrations were obtained using enzyme-linked immunosorbent assays. Thirty-two participants (IT: n = 13, OT: n = 19) with an average age of 63 years and BMI of 27.5, spent 78% of their waking hours engaged in sedentary behavior outside of exercise training. Significant correlations were observed between light physical activity (LPA) outside of exercise training and QOL in IT (r = 0.626, p = 0.030), and fatigue in OT (r = 0.553, p = 0.021). Moderate to vigorous physical activity (MVPA) outside of exercise training significantly correlated with leg press strength (r = 0.700, p = 0.008) in IT, and cardiorespiratory fitness (r = 0.440, p = 0.013) when groups were combined. Concentrations of NGF did not differ between groups, and in IT, BDNF was positively related to LPA outside of training and was significantly lower (87 ± 28.5 pg/mL) than in OT (137 ± 54 pg/mL; p=0.010). While structured exercise programs should focus on improving cardiorespiratory fitness and muscular strength during exercise training, these programs should consider physical activity outside of training, if well-tolerated, to potentially further lower fatigue and improve QOL in cancer survivors.

Children's physical activity behavior following a supervised physical activity program in pediatric oncology

BACKGROUND

The theory of planned behavior (TPB) model and its components have been applied to comprehend the adoption of physical activity along with informational and motivational parameters. Thus, the first aim of this exploratory study was to explore the evolution of children's physical activity levels over a supervised physical activity program. The second aim was to describe the evolution of TPB measures, self-reported fitness and self-esteem in the physical domain to better understand children's physical activity behavior over the course of the physical activity program.

METHODS

A total of 16 children (8 boys and 8 girls) with cancer answered psychosocial questionnaires before and after a supervised physical activity program to explore the TPB measures, self-reported fitness, self-esteem in the physical domain and their daily physical activities.

RESULTS

A significant increase of 13.8 min/day [95% CI (16.7; 10.8); p < 0.0001; d = 1.4] of daily MVLPA was observed between the time before (9.3 ± 9.1 min/day) and after (23.1 ± 10.8 min/day) the physical activity program. We found that the physical activity program positively impacted children's TPB measures (mean in attitude, identity, facilitating factors, self-confidence and intention) and MVLPA levels. The TPB model explained 36.2% of the variance in MVLPA by injunctive norms after the physical activity program.

CONCLUSION

This study highlighted the need to provide children with physical activity support as soon as the cancer is diagnosed and showed that children's physical activity behaviors were facilitated by familial support measured by injunctive norms.

The impact of cancer on theory of planned behavior measures and physical activity levels during the first weeks following cancer diagnosis in children

BACKGROUND

The theory of planned behavior (TPB) is used to document children's health behaviors linked to their physical activity. The TPB model and its components have been applied to comprehend the adoption of physical activity along informational and motivational parameters. Thus, this exploratory study aims to assess the evolution of children's physical activity levels (MVLPA) during the first weeks of their cancer, in addition to documenting the evolution of the TPB measures, self-reported fitness, and self-esteem in the physical domain to better understand children's physical activity behavior.

METHODS

A total of 16 children (8 boys and 8 girls) with cancer answered psychosocial questionnaires at the diagnosis of cancer (time 1) and at 6 to 8 weeks (time 2) to assess the TPB measures, self-reported fitness, self-esteem in the physical domain, and their daily physical activities.

RESULTS

A significant decrease of 41.2 min/days of daily MVLPA was observed between the time at cancer diagnosis (50.5 ± 32.8 min/days) and 6 to 8 weeks after the first interview (9.3 ± 9.1 min/days). We found that the time after the diagnosis of cancer negatively impacted children's TPB measures (mean in attitude, injunctive norms, identity, facilitating factors, self-confidence, and intention) and MVLPA levels. The TPB model explains 40% of the variance in MVLPA by the injunctive norms during the first weeks following cancer diagnosis in children.

CONCLUSION

The findings of this study highlight the negative impacts of cancer on children's TPB measures, self-reported fitness, and self-esteem in the physical domain and self-reported MVLPA levels over 4 to 6 weeks following the diagnosis. These findings help to better understand the effect of cancer diagnosis on children's physical activity behavior.

Peer-Based Strategies to Support Physical Activity Interventions for Older Adults: A Typology, Conceptual Framework, and Practice Guidelines

Despite the documented and well-publicized health and well-being benefits of regular physical activity (PA), low rates of participation have persisted among American older adults. Peer-based intervention strategies may be an important component of PA interventions, yet there is inconsistent and overlapping terminology and a lack of clear frameworks to provide a general understanding of what peer-based programs are exactly and what they aim to accomplish in the current gerontological, health promotion literature. Therefore, a group of researchers from the Boston Roybal Center for Active Lifestyle Interventions (RALI) collaborated on this paper with the goals to: (a) propose a typology of peer-based intervention strategies for use in the PA promotion literature and a variety of modifiable design characteristics, (b) situate peer-based strategies within a broader conceptual framework, and (c) provide practice guidelines for designing, implementing, and reporting peer-based PA programs with older adults. We advance clarity and a common terminology and highlight key decision points that offer guidance for researchers and practitioners in using peers in their health promotions efforts, and anticipate that it will facilitate appropriate selection, application, and reporting of relevant approaches in future research and implementation work.

Target population's requirements on a community-based intervention for stimulating physical activity in hard-to-reach physically disabled people: an interview study

Purpose: To explore ideas of the target population about a community-based intervention to stimulate physical activity in hard-to-reach physically disabled people. Materials and methods: Semi-structured interviews were performed with 21 physically disabled people, and analyzed using thematic analyses. Findings were interpreted using the integrated Physical Activity for People with a Disability and Intervention Mapping model. Results: The intervention should aim to stimulate intrinsic motivation and raise awareness for the health effects of physical activity. It should provide diverse activities, increase visibility of these activities, and improve image of physical activity for physically disabled people. Participants suggested to provide individual coaching sessions, increase marketing, present role models, and assign buddies. Potential users should be approached personally through intermediate organizations, or via social media and word of mouth promotion. Participants suggested that users, government, sponsors, and health insurers should finance the intervention. Self-responsibility for being physically active was strongly emphasized by participants. Conclusions: An intervention to stimulate physical activity in hard-to-reach physically disabled people should be individualized, include personal support, and should include marketing to improve image of physical activity of physically disabled people. The intervention that fulfills these requirements should be developed and tested for effects in future research. Implications for rehabilitation An intervention to stimulate physical activity in physically disabled people should aim to raise awareness for the health effects of physical activity, stimulate intrinsic motivation, offer diverse activities, increase the visibility of the possible activities, and improve the image of physical activity for physically disabled people. An intervention should include both individual- and environmental-level intervention methods. Physically disabled people most emphasized individual-level characteristics of an intervention. For intervention development, professionals should take into account that physically disabled people believe that being physically active is a person's own responsibility.

Motivational profiles, accelerometer-derived physical activity, and acute diabetes-related symptoms in adults with type 2 diabetes

Background

Using self-determination theory, the objective of this study was to examine, over a one-month period, how physical activity (PA) motivation would influence accelerometer-derived PA behavior, and ultimately, acute diabetes-related symptoms burden among adults with type 2 diabetes (T2D adults). Using both a person and variable-centered approach, this objective was attained by means of: 1) investigating the indirect effect of PA participation on the relationship between PA motivation and acute diabetes-related symptom burden and 2) examining whether participants who met PA recommendations (i.e., 150 min of moderate-to-vigorous PA per week) would experience less acute diabetes-related symptom burden over a one-month period.

Methods

A two-wave prospective longitudinal design was used. At time 1, participants completed a questionnaire assessing their PA motivation and were asked to wear an ActiGraph GT3x accelerometer for four consecutive weeks. At time 2, they completed a short questionnaire assessing their acute diabetes-related symptoms (i.e., symptoms related to fatigue, cognitive distress, hyperglycemia, and hypoglycemia). The final sample includes 165 adults (89 or 53.61% women) aged from 26 to 75 years (M = 62.05, SD = 8.75) with T2D, which provided at least 21 valid days of accelerometer-derived data.

Results

First, results of a path analysis demonstrated that over a one-month period, the average number of minutes spent practicing moderate to vigorous PA per week mediated the relationship between intrinsic and external PA motivation and the level of burden associated with the following diabetes-related symptoms: fatigue, cognitive distress, and hyperglycemia. In addition, results of covariance analyses showed that participants meeting PA recommendations also reported significantly less burden associated with these three symptoms over a month period. Then, the existence of four motivational profiles (Self-Determined, High Introjected, Low Motivation, and Non-Self-Determined) was confirmed using a k-means analysis. Results of covariance and chi-square analyses further showed, respectively, that compared to other motivational profiles, the Self-Determined profile was associated with a higher score on weekly PA participation and meeting PA recommendations.

Conclusions

The results highlight the importance of promoting autonomous motives for PA participation among T2D adults. They also suggest that T2D adults meeting PA recommendations experience less acute diabetes-related symptoms burden, which further support the importance of their PA motivation.

Self-regulation of eating and physical activity is lower in obese female college students as compared to their normal weight counterparts

OBJECTIVE

Obesity is characterized, among other features, by overeating, reduced physical activity and an abnormal accumulation of body fat. These features are thought to result, at least in part, from the individual's inability to self-regulate their eating and physical activity behaviors (E&PaB). Self-regulation of the E&PaB is a three-step sequential process: self-observation, self-evaluation and self-reaction. However, it is yet unclear whether deficient self-regulation of E&PaB could predispose, facilitate and/or consolidate obesity. Unraveling this issue is fundamental in order to more precisely define the role of self-regulation of E&PaB in the management of obesity.

METHODS

This research was focused on the question of whether or not self-regulation of E&PaB is related to obesity in female undergraduate students. This population segment seems especially vulnerable to developing obesity since they undergo a significant shift of their E&PaB upon their university enrollment. To address this question, a cross-sectional study with 108 female undergraduate students with normal weight (n = 80) or obesity (n = 28) was performed, in which self-regulation of eating habits and physical activity was measured by two validated scales and a personal data questionnaire.

RESULTS

Female undergraduate students displaying lower E&PaB self-reactions were consistently overweight or obese. In addition, a multivariate analysis identified high levels of self-reaction towards eating habits related to a minor presence of overweight issues or obesity.

CONCLUSION

Self-regulation should be an essential component in the strategies for obesity prevention as an integral approach that must include orientation about healthy eating and physical activity behaviors. In addition, further studies on the effect of self-regulation in the treatment of the obesity are needed.
