The influence of housing characteristics on leisure-time sitting. A prospective cohort study in Danish adults

Life-Space Mobility and Objectively Measured Movement Behavior in Older Adults with Hypertension after Receiving COVID-19 Vaccination

This study examined the changes in life-space (LS) mobility and objectively measured movement behavior in older adults with hypertension after receiving the COVID-19 vaccine and their associations with housing type. A total of 32 participants were included in this exploratory longitudinal study with a 1-year follow-up. LS mobility and accelerometer-based physical activity (PA) and sedentary behavior (SB) were assessed before and ~2 months after receiving COVID-19 vaccination. Participants residing in apartment/row housing showed an increase in LS mobility composite score (β = 14, p < 0.05). In addition, they showed an increase in light PA on weekdays and the weekend (β = 3.5%; β = 6.5%; p < 0.05) and a decrease in SB on weekdays and the weekend (β = -3.7%; β = -6.6%; p < 0.05). Furthermore, changes in SB pattern were found (less time spent in bouts of ≥10 and 30 min, more breaks/day and breaks/hour). Significant associations were found between changes in LS mobility composite score and PA (positive association) and SB (negative association) in older adults residing in apartment/row housing (p < 0.05). Older adults with hypertension, particularly those who resided in houses with limited outdoor space (apartment/row housing), showed positive changes in LS mobility and objectively measured movement behavior in a period after receiving the COVID-19 vaccine and characterized by social distancing policies without mobility restrictions when compared with the period of social distancing policies with high mobility restrictions and without vaccine.

Distributions and determinants of time spent outdoors among school-age children in China

BACKGROUND

The outdoor time is a key factor that determines children's exposure to environmental contaminants. Meanwhile, children reap numerous physical and mental health benefits from playing outdoors.

OBJECTIVE

This study aimed to characterize the distributions and identify determinants of the time spent outdoors among school-age children in China.

METHODS

The study recruited 41,439 children aged 6-17 years in Mainland China using a multi-stage cluster random sampling method. This sample was nationally representative with sample weights created to account for the complex survey design. Information on time-activity patterns were collected with a standard questionnaire through face-to-face interviews. Frequency distributions of time outdoors were created by age group, gender, region, and other sociodemographic factors with sample weights. The key factors influencing time outdoors were identified using multivariable linear regression models.

RESULTS

The grand mean (±standard deviation) time outdoors was 101 ± 51 min/day for all the study participants, 22.3% having <60 min/day. Children spent longer time outdoors in warm seasons and on weekends. Children's outdoor time was significantly influenced by gender, age, urbanicity, region, annual total household expenditure, building environment, and meteorological conditions (annual mean temperature, sunshine time, and precipitation). Girls, 15-17 year old, and urban children had 6 min/day, 8 min/day, and 13 min/day less outdoor time than boys, 6-8 year old, and rural children, respectively. Most significantly, urban girls and high school students had the shortest outdoor time. The cement ground was the most important type of ground for children playing outside.

SIGNIFICANCE

This was the first national-scale study that characterized the time outdoors and where is it spent among school-age children in China. It revealed that one-fifth of Chinese children spent less than one hour outdoors every day, and urban girls had particular "indoor tendencies". The findings provide bases for future interventions and guidelines aimed at promoting children's physical activities.

Individual, Sociodemographic, and Environmental Factors Related to Physical Activity During the Spring 2020 COVID-19 Lockdown

Background: Research has shown important between-individual variations in physical activity (PA) during the COVID-19 lockdown. Objectives: The objectives of this is study are to examine the individual, sociodemographic, and environmental factors related to PA during the spring 2020 COVID-19 lockdown in France and to explore the mediating and moderating role of intention and self-efficacy toward PA in the relationships between sociodemographic/environmental variables and PA. Design: In this cross-sectional study, participants living in France (N = 386) completed an online survey between March 30 and April 10, 2020. Method: Minutes per week of moderate-to-vigorous PA during the lockdown; usual physical activity before the lockdown; and psychological (e.g., intention, self-efficacy, and autonomous and controlled motivation), sociodemographic (gender, age, and number of children), and environmental (habitat surface area and type of housing) factors were measured in the survey. Multiple linear regressions were used to investigate the role of these predictors on PA. Intention and self-efficacy were also examined as moderators and mediators of the association between sociodemographic/environmental factors and PA. Results: Usual physical activity before the COVID-19 lockdown, intention toward PA, habitat surface area, and controlled motivation significantly predicted PA during the lockdown. No mediating effects of intention or self-efficacy were found. Intention significantly moderated the association between gender and PA and the association between part-time work and PA. Conclusions: PA during the COVID-19 lockdown was mainly predicted by individual factors and notably usual PA. These results highlight the important role of habits in a highly changing context.

Housing type is associated with objectively measured changes in movement behavior during the COVID-19 pandemic in older adults with hypertension: An exploratory study

Purpose

To investigate the association between housing characteristics with objectively measured changes in physical activity (PA) and sedentary behavior (SB) during the COVID-19 pandemic in older adults with hypertension.

Methods

Thirty-five older adults with hypertension were included in this exploratory study. Accelerometer-based PA and SB measures were assessed before and during a period of social distancing policy imposed due to the COVID-19 pandemic. Housing type, housing surface area and household size were tested as predictors of changes in PA and SB. A generalized linear mixed model was used for the analysis.

Results

Housing type was associated with changes in PA and SB. Individuals residing in an apartment showed a greater decrease in light PA on weekdays (β= –65 min/day, p=0.035) and a trend for an increase in SB (β= 55 min/day, p=0.056) compared to those residing in a detached house. Individuals residing in a row house showed a greater decrease in moderate-vigorous PA (β= –10 min/day, p=0.037) and steps/day (β= –2064, p=0.010) compared to those residing in a detached house. Individuals residing in an apartment showed a greater decrease in light PA on the weekends (β= –83 min/day, p=0.015) and an increase in SB (β= 72 min/day, p=0.036) compared to those residing in a detached house. No association was found for housing surface area and household size.

Conclusions

Older adults with hypertension residing in an apartment or row house have greater unhealthy changes in movement behavior during the COVID-19 pandemic. Further studies are needed to confirm our preliminary findings.

Built form and depression among the Chinese rural elderly: a cross-sectional study

OBJECTIVES

Few data on the association between housing structure and depression among rural elders in China are available. We examined the impact of built forms on depression.

DESIGN

This is a cross-sectional study.

SETTING

A representative sample of rural residents aged 60 years or older in China.

PARTICIPANTS

A total of 5090 older adults in 2019 in rural Suzhou, China.

OUTCOME MEASURES

Associations of built form with odds of probable and possible depression.

RESULTS

There was significant difference among elders living in varied sizes of house. Older age (vs 60-64 years: 75-79 years AdjOR, 1.737; 95% CI, 1.309 to 2.305; ≥80 years AdjOR, 2.072; 95% CI, 1.439 to 2.981), male sex (AdjOR, 0.719; 95% CI, 0.593 to 0.871), single (AdjOR, 1.303; 95% CI, 1.032 to 1.646), self-care disability (AdjOR, 4.761; 95% CI, 3.960 to 5.724), three or more chronic diseases (AdjOR, 2.200; 95% CI, 1.657 to 2.920), living alone (AdjOR, 1.443; 95% CI, 1.059 to 1.966), living in cottage (AdjOR, 1.426; 95% CI, 1.033 to 1.967), living space (vs <50 m2: 201-250 m2 AdjOR, 0.566; 95% CI, 0.359 to 0.893; >250 m2 AdjOR, 0.337; 95% CI, 0.223 to 0.511) and space per person (vs <30 m2: 30- m2 AdjOR, 0.502; 95% CI, 0.362 to 0.697; 40- m2 AdjOR, 0.473; 95% CI, 0.347 to 0.646; 50- m2 AdjOR, 0.418; 95% CI, 0.339 to 0.515) were associated with risk of depression among Chinese rural elders.

CONCLUSION

The built form was significantly and meaningfully associated with depression among Chinese rural elders. More attention should be paid to preventing mental illness among the rural elderly living in the small housing area and cottages in China.

Association between the living environment and the risk of arterial hypertension and other components of metabolic syndrome

Background

Metabolic syndrome (MS) is characterized by numerous metabolic risk factors. We investigated the associations between a long-term exposure to ambient air pollution and the residential distance to green spaces (GS) and major roads with the development of arterial hypertension (AH) and some components of MS. These associations were assessed among persons living in private and multi-story houses (MH).

Methods

We selected 1354 participants for the population study from MONICA (Multinational Monitoring of Trends and Determinants in Cardiovascular Disease Program). The exposures to PM10, PM2.5, and NO2 levels were assessed by using the LUR models for Kaunas City.

Results

In the participants who lived in MH, the residential distance to a major road closer than 200 m and the residential exposure to PM10 and PM2.5 levels above the median were associated with a higher risk of AH (the adjusted relative risks (RRs), respectively, were 1.41(1.10–1.81), 1.19(1.01–1.42) and 1.27(1.07–1.52)). In these participants, the residential exposure to a PM10 level above the median was associated with a higher risk of reduced high density lipoprotein (RHDL) (RR = 1.46(1.05–2.05)). A negative impact of the traffic air pollutants on the incidence of AH, RHDL cholesterol and high triglyceride levels was observed only in the participants who lived in MH.

Associations of neighborhood environmental attributes with adults' objectively-assessed sedentary time: IPEN adult multi-country study

Neighborhood environmental attributes have been found to be associated with residents' time spent walking and in physical activity, in studies from single countries and in multiple-country investigations. There are, however, mixed findings on such environmental relationships with sedentary (sitting) time, which primarily have used evidence derived from single-country investigations with self-reported behavioral outcome measures. We examined potential relationships of neighborhood environmental attributes with objectively-assessed sedentary time using data from 5712 adults recruited from higher and lower socio-economic status neighborhoods in 12 sites in 10 countries, between 2002 and 2011. Ten perceived neighborhood attributes, derived from an internationally-validated scale, were assessed by questionnaire. Sedentary time was derived from hip-worn accelerometer data. Associations of individual environmental attributes and a composite environmental index with sedentary time were estimated using generalized additive mixed models. In fully adjusted models, higher street connectivity was significantly related to lower sedentary time. Residential density, pedestrian infrastructure and safety, and lack of barriers to walking were related to higher sedentary time. Aesthetics and safety from crime were related to less sedentary time in women only. The predicted difference in sedentary time between those with the minimum versus maximum composite environmental index values was 71 min/day. Overall, certain built environment attributes, including street connectivity, land use mix and aesthetics were found to be related to sedentary behavior in both expected and unexpected directions. Further research using context-specific measures of sedentary time is required to improve understanding of the potential role of built environment characteristics as influences on adults' sedentary behavior.

Promoting physical activity in high-poverty neighborhood parks: A cluster randomized controlled trial

Although physical activity can help mitigate or prevent multiple chronic diseases, most people in the U.S., especially high-poverty minority groups, engage in insufficient levels of physical activity. To test ways to promote more physical activity in high-poverty area public parks we conducted a randomized controlled intervention trial. After completing baseline measures of park-based physical activity using systematic direct observation three times/day each month for six months and assessing preferences for park programming among 1445 residents living within 1 mile of study parks, we randomized 48 parks in high poverty neighborhoods in the City of Los Angeles, California during 2013-2014 to four study arms: 1) free physical activity classes over a 6-month period, 2) a frequent user program where participants could win prizes based upon the number of visits they made to the park, 3) both the programs, and 4) neither one (control condition). We re-measured park use in 2014-2015 using the same methods during the six months the intervention programs were in operation. A total of 2047 free park classes were offered attracting 16,718 participants. The frequent user programs enrolled 1452 individuals and prizes were awarded to 830. Residents in the two study arms with free classes were more likely to report being aware of and participating in park-based physical activity programs; however, overall observed park-based physical activity increased similarly across all study arms. The process evaluation uncovered several barriers to program implementation, including inconsistent scheduling of classes, partly due to safety concerns among instructors. Multiple social factors interfere with leisure time physical activity among low-income populations, suggesting modest interventions may be insufficient to overcome these issues. Although new park programs can attract users, new programs alone may be insufficient to increase overall park use in low-income neighborhoods at times when the programs are not taking place.

A systematic review of correlates of sedentary behaviour in adults aged 18-65 years: a socio-ecological approach

Background

Recent research shows that sedentary behaviour is associated with adverse cardio-metabolic consequences even among those considered sufficiently physically active. In order to successfully develop interventions to address this unhealthy behaviour, factors that influence sedentariness need to be identified and fully understood. The aim of this review is to identify individual, social, environmental, and policy-related determinants or correlates of sedentary behaviours among adults aged 18–65 years.

Methods

PubMed, Embase, CINAHL, PsycINFO and Web of Science were searched for articles published between January 2000 and September 2015. The search strategy was based on four key elements and their synonyms: (a) sedentary behaviour (b) correlates (c) types of sedentary behaviours (d) types of correlates. Articles were included if information relating to sedentary behaviour in adults (18–65 years) was reported. Studies on samples selected by disease were excluded. The full protocol is available from PROSPERO (PROSPERO 2014:CRD42014009823).

Results

74 original studies were identified out of 4041: 71 observational, two qualitative and one experimental study. Sedentary behaviour was primarily measured as self-reported screen leisure time and total sitting time. In 15 studies, objectively measured total sedentary time was reported: accelerometry (n = 14) and heart rate (n = 1). Individual level factors such as age, physical activity levels, body mass index, socio-economic status and mood were all significantly correlated with sedentariness. A trend towards increased amounts of leisure screen time was identified in those married or cohabiting while having children resulted in less total sitting time. Several environmental correlates were identified including proximity of green space, neighbourhood walkability and safety and weather.

Conclusions

Results provide further evidence relating to several already recognised individual level factors and preliminary evidence relating to social and environmental factors that should be further investigated. Most studies relied upon cross-sectional design limiting causal inference and the heterogeneity of the sedentary measures prevented direct comparison of findings. Future research necessitates longitudinal study designs, exploration of policy-related factors, further exploration of environmental factors, analysis of inter-relationships between identified factors and better classification of sedentary behaviour domains.
