A systematic review examining associations between physical activity, sedentary behaviour, and sleep duration with quality of life in older adults aged 65 years and above.

This systematic review examined the associations between movement behaviours (i.e., physical activity, sedentary behaviour, and sleep duration) and quality of life (QOL) in adults ≥65 years of age. Four databases were searched in June 2021. Studies were eligible for inclusion if published within the last 20 years, peer-reviewed, examined apparently healthy older adults, and analysed ≥2 movement behaviours together. QOL was represented by the World Health Organization Quality of Life measure which conceptualizes QOL by distinct domains. Study results were categorized and presented by domain. Risk of bias was completed for all included studies using methods described in the Cochrane Handbook. Thirty-one studies with 307 292 participants were included that examined QOL outcomes across seven domains: superdomain (composite measures), perceived physical health, mental and psychological states, level of independence, social relationships, environment, and general health. Findings indicated that moderate-to-vigorous intensity physical activity was favourably associated with QOL. Time re-allocation studies that showed moving time into physical activity from sedentary behaviour were associated with favourable QOL changes. The evidence regarding sedentary behaviour and sleep duration was inconsistent. The quality of evidence was very low for all domains. In conclusion, there is consistent evidence that physical activity improves QOL in adults ≥65 years of age.

Ambient air pollution and movement behaviours: A scoping review.

This scoping review summarizes the literature about how ambient (outdoor) air pollution impacts movement behaviours (i.e., physical activity, sedentary behaviour, and sleep), or beliefs about movement behaviours. Of 6552 potential documents, 58 documents and 218 findings were included in the final synthesis. Most studies were from the United States and China, involved cross-sectional designs, and included mixed age groups. Overall, unfavourable changes/associations (i.e., decreased/lower physical activity, increased/higher sedentary-related behaviour, and decreased/lower sleep duration and quality) or no change/association in movement behaviours in relation to ambient air pollution were identified. Our findings suggest that more attention should be given to understanding the impact of ambient air pollution on movement behaviours in general and in diverse countries and vulnerable populations such as children or older adults.

Climate change, 24-hour movement behaviors, and health: a mini umbrella review.

BACKGROUND: The worsening climate change and alarming prevalence of communicable and non-communicable diseases continue to threat human life and existence. Accumulating evidence suggests that favorable patterns of 24-h movement behaviors, high physical activity, low sedentary behavior, and adequate sleep, may positively contribute to achieving dual benefits of climate change mitigation and disease prevention. The purposes of this mini umbrella review were to summarize the most up-to-date, high-level evidence exploring the relationships between climate change, 24-h movement behaviors, and health and elaborate on the mechanisms linking the three variables of interest. METHODS: A systematic search of electronic databases was performed in PubMed and Google Scholar during March-October 2020. Inclusion criteria were: (1) systematic review; (2) reviewed relationships between climate change and movement behaviors and/or health in any directions; (3) written in English; (4) published in 2010-2020. Narrative synthesis was conducted to highlight the main relationships observed and address the current state of knowledge and priorities for future research. In order to illustrate the potential mechanisms between climate change, movement behaviors, and health, the main results from included systematic reviews were summarized and a conceptual framework was developed for future research. RESULTS: Based on the evidence from eight systematic reviews published in the past decade, multi-directional (i.e., uni-, bi-, or U-shaped) links were observed between climate change and varying human health outcomes. However, little is understood about the association between climate change and 24-h movement behaviors. Two reviews suggested the negative impact of climate change on sleep and bi-directional relationships between climate change and physical activity/sport. One review included two studies suggesting the unfavorable impact of climate change on sedentary behavior; however, the evidence was limited. Finally, no reviews examined the mechanisms by which climate change, movement behaviors, and health impact one another. Based on the findings of this mini umbrella review, a conceptual framework is proposed that could guide future work to unpack mechanisms between climate change, movement behaviors, and health. CONCLUSIONS: This mini umbrella review highlights the importance of better understanding the mechanisms between climate change, movement behaviors, and health in developing effective mitigation and adaptation strategies to climate change, while paying close attention to vulnerable countries/communities/population groups.

Systematic review of the correlates of outdoor play and time among children aged 3-12 years.

BACKGROUND: Due to the myriad of benefits of children's outdoor play and time, there is increasing concern over its decline. This systematic review synthesized evidence on the correlates of outdoor play and outdoor time among children aged 3-12 years. METHODS: A total of 12 electronic databases in five different languages (Chinese, English, Korean, Spanish, Portuguese) were searched between October 28, 2019 and July 27, 2020. Covidence software was used for screening and Microsoft Excel with a predesigned coding form was used for data extraction. Evidence was synthesized and correlates were categorized using the socioecological model framework. RESULTS: Based on 107 studies representing 188,498 participants and 422 childcare centers from 29 countries, 85 studies examined potential correlates of outdoor play while 23 studies examined that of outdoor time (one examined both). The duration of outdoor play and outdoor time ranged between 60 and 165 min/d and 42-240 min/d, respectively. Out of 287 (outdoor play) and 61 (outdoor time) potential correlates examined, 111 correlates for outdoor play and 33 correlates for outdoor time were identified as significant correlates. Thirty-three variables were identified as key/common correlates of outdoor play/time, including eight correlates at the individual level (e.g., sex/gender, race/ethnicity, physical activity), 10 correlates at the parental level (e.g., parental attitude/support/behavior, parenting practice), nine at the microsystem level (e.g., proximal home/social environment such as residence type, peer influence), three at the macrosystem/community level (e.g., availability of space children can play), and three at the physical ecology/pressure for macrosystem change level (e.g., seasonality, rurality). No key correlates were found at the institutional level. CONCLUSIONS: Individual, parental, and proximal physical (home) and social environments appear to play a role in children's outdoor play and time. Ecological factors (i.e., seasonality, rurality) also appear to be related to outdoor play/time. Evidence was either inconsistent or lacking at institutional and macrosystem/community levels. Standardizing terminology and measures of outdoor play/time is warranted. Future work should investigate the interactions and processes of multiple variables across different levels of socioecological modelling to better understand the mechanisms through which outdoor play/time opportunities can be optimized for children while paying special attention to varying conditions in which children are born, live, and play.

Sustainable by design: a systematic review of factors for health promotion program sustainability.

BACKGROUND: Sustaining health promotion programs (HPP) is critical to maintain their intended health benefits, community capacity, and to optimize resources and investment. However, not all programs are sustained beyond their initial implementation period. This is partly due to uncertainty regarding sustainability: lack of a clear definition; infrequent use of a sustainability framework; and lack of understanding of the factors that influence sustainability. The aim of this systematic review is to identify barriers and facilitators that promote or inhibit the sustainability of HPP, particularly those that can be considered in program planning. METHODS: Two search strategies were used: 1) electronic database searching; and 2) grey literature searching. Inclusion criteria included papers published since 1998, in English, focusing on the sustainability of HPP that explicitly used a sustainability framework and specifically reported on facilitators and barriers to sustainability. Exclusion criteria included papers that addressed environmental, system or sector sustainability. Quality assessment was conducted on all included papers and a quality assessment tool was developed for grey literature. Data analysis included a thematic analysis, using an a priori framework to initially code barriers and facilitators, which were then grouped into factors for HPP sustainability. Factors were then analyzed for frequency, importance, and relevance, and categorized into one of three tiers. RESULTS: Sixteen papers were included in this review. Eleven definitions of sustainability and 13 sustainability frameworks were used. A total of 83 barriers and 191 facilitators were identified and categorized into 14 factors: nine from the a priori framework, and five additional ones based on the results of our analysis. Tier 1 factors were the most important for sustainability with organizational capacity scoring the highest; tier 3, the least important. CONCLUSION: This review provides clarity regarding existing definitions of sustainability and sustainability frameworks. It identifies fourteen factors that influence program sustainability, which practitioners can consider when planning, developing and implementing HPP. In addition, it is important for practitioners to clearly articulate program elements that should be sustained, define sustainability as it relates to the context of their program, select a sustainability framework to guide their work, and consider these factors for sustainability.

Global region of birth is an independent risk factor for type 2 diabetes in Stockholm, Sweden.

Background: In Stockholm, type 2 diabetes (T2D) is a public health concern and much more prevalent in areas with a high proportion of foreign-born individuals. One in five individuals in Stockholm County are born outside of Sweden, and we therefore investigated if global region of birth was associated with diabetes risk, adjusting for established risk factors. Cross-sectional data from the population-based Stockholm Public Health Survey 2010 ( N = 69 115) was combined with registry-based information on country of birth grouped into eight global geographical regions. Cases of T2D were identified through self-reported physician-diagnosed diabetes and age at diagnosis. Region of birth was the independent risk factor and multivariable logistic regression analysis was performed adjusting for the risk factors age, sex, weight status, educational level, multiple dietary factors, tobacco, alcohol and physical activity. T2D prevalence was 5.1% in the sample. Relative to Swedish-born participants, higher odds ratio (OR) were found in those born in Asia [OR 3.2, 95% confidence interval (CI) 2.2-4.7], Sub-Saharan Africa (OR 2.5, 95% CI 1.5-4.1) and North Africa/the Middle East (OR 2.1, 95% CI 1.6-2.8), after adjustment for established risk factors. Participants from Eastern Europe and Latin America had an elevated risk but this did not remain after adjustment for other risk factors. Region of birth was found to be an independent risk factor for T2D for participants born in Asia, Africa and the Middle East. This increased risk should be taken into consideration when allocating resources for prevention, detection and care.
