Mode shifting in school travel mode: examining the prevalence and correlates of active school transport in Ontario, Canada

<p>Abstract</p> <p>Background</p> <p>Studies examining the correlates of school transport commonly fail to make the distinction between morning and afternoon school trips. The purpose of this study was to examine the prevalence and correlates of mode shift from passive in the morning to active in the afternoon among elementary and secondary school students in Ontario, Canada.</p> <p>Methods</p> <p>Data were derived from the 2009 cycle of the Ontario Student Drug Use and Health Survey (OSDUHS). 3,633 students in grades 7 through 12 completed self-administered questionnaires. Socio-demographic, behavioural, psychological, and environmental predictors of active school transport (AST) were assessed using logistic regression.</p> <p>Results</p> <p>Overall, 47% and 38% of elementary school students reported AST to and from school, respectively. The corresponding figures were 23% and 32% for secondary school students. The prevalence of AST varied temporarily and spatially. There was a higher prevalence of walking/biking found for elementary school students than for secondary school students, and there was an approximate 10% increase in AST in the afternoon. Different correlates of active school transport were also found across elementary and secondary school students. For all ages, students living in urban areas, with a shorter travel time between home and school, and having some input to the decision making process, were more likely to walk to and from school.</p> <p>Conclusions</p> <p>Future research examining AST should continue to make the analytic distinction between the morning and afternoon trip, and control for the moderating effect of age and geography in predicting mode choice. In terms of practice, these variations highlight the need for school-specific travel plans rather than 'one size fits all' interventions in promoting active school transport.</p

What Role does the Built Environment Play in Determining School Travel in Ontario?

Given declines in physical activity among youth, active school travel (AST) is of increasing policy, practice and research interest. The effectiveness of the current interventions to promote AST is modest. Moreover, the current literature has little support on the associations between the built environment and AST. Therefore, to inform future interventions, this research program assesses in whom particular built environment attributes promote AST. My research program consists of three studies. The first study is a systematic review that identifies current knowledge on the associations between GIS-measures of the built environment attributes and AST and methodological limitations in the literature. Then, the second study identifies the prevalence, and individual, household, and environmental correlates of AST i) in the morning and ii) in the afternoon in Ontario, Canada. The third study identifies how objective measures (GIS-measures) of built environment attributes relate to AST and whether age, gender, and time of travel moderate such associations. The systematic review concluded that the associations between the GIS measures of the built environment and AST were weak except the distance to school. A number of methodological limitations contributed to these inconsistencies. The prevalence of AST varied by period of time (morning vs. afternoon) and across Ontario. Being involved in the decision-making process on school travel was an important individual correlate of AST. Moreover, a school neighbourhood with high residential density, and well connected street network with the presence of sidewalk and traffic controls around school was associated with walking school trips but such associations depend on age, gender, and time of travel. Future interventions should involve youth as advocates to promote AST. Moreover, intensifying school neighbourhoods, constructing well-connected street networks, and minor infrastructure improvements such as sidewalk and traffic control installment are recommended environmental strategies to promote AST together alongside interventions to address the age, gender, and temporal differences.Ph.D.2020-03-26 00:00:0

Perceived Benefits and Harms of the COVID-19 Pandemic on Family Well-Being and Their Sociodemographic Disparities in Hong Kong: A Cross-Sectional Study

We assessed the perceived benefits and harms of COVID-19 on family and their associations with sociodemographic factors in Chinese adults in Hong Kong. We conducted an online population-based survey and collected 4891 responses in 6 days. Prevalence estimates were weighted by sex, age, and education of the general population, and associations were analyzed using logistic regression. Our results showed both perceived benefits: 19.0% for family physical health, 7.2% family mental health, and 13.5% family relationships; and harms: 2.3% for family physical health, 37.9% family mental health, 18.6% family relationships, and 37.8% decreased family income. More female or older respondents reported perceived benefits but fewer of them reported perceived harms. More respondents with higher than lower socioeconomic scores (SES) reported perceived benefits on family physical and mental health and family relationships, but more respondents with lower than higher SES reported perceived harm on family income. As the pandemic continues with uncertainties, further studies on the dynamics of benefits and harms are needed. Urgent and additional assistance to underprivileged families and at-risk individuals are needed to reduce the inequities amidst the COVID-19 pandemic

Cardiovascular Health of Construction Workers in Hong Kong: A Cross-Sectional Study

Background: Given a shortage of construction workers, it is important to develop strategies to avoid early retirement caused by cardiovascular diseases in Hong Kong. Objectives: (1) to describe the cardiovascular health of construction workers in Hong Kong, (2) to examine the demographic differences in cardiovascular health, and (3) to examine the association between health behaviors and cardiovascular health factors. Methods: 626 registered construction workers were included in the analysis. Blood chemistry, blood pressure, weight, and height were measured. Face-to-face questionnaire interviews for health behaviors were conducted. Results: Approximately two-thirds of the construction workers achieved only three out of the seven “ideal” cardiovascular health metrics. The younger, more educated, and female subjects had better cardiovascular health scores than the older, less educated, and male counterparts. Fish and seafood consumption was associated with (1) ideal weight status and (2) ideal cholesterol level, whereas less soft drink consumption was associated with ideal cholesterol level. Conclusions: The findings highlighted the importance of promoting cardiovascular health in the construction industry. This study provided some insights for future interventions, which should include increasing fish and seafood intake, decreasing soft drink consumption, and enhancing the health literacy amongst older, less educated, and male construction workers

A Population Study on COVID-19 Information Sharing: Sociodemographic Differences and Associations with Family Communication Quality and Well-Being in Hong Kong

Family support through the sharing of information helps to shape and regulate the health and behaviours of family members, but little is known about how families are sharing COVID-19-related information, or about its associations with family communication quality and well-being. We examined the associations of COVID-19 information sharing methods with sociodemographic characteristics, the perceived benefits of information communication and technology (ICT) methods, and family communication quality and well-being in Hong Kong. Of 4852 respondents (53.2% female, 41.1% aged over 55 years), the most common sharing method was instant messaging (82.3%), followed by face-to-face communication (65.7%), phone (25.5%) and social media (15.8%). Female sex (adjusted prevalence ratio (aPR) 1.09), older age (aPRs 1.14&ndash;1.22) and higher household income (aPR 1.06) (all p &le; 0.04) were associated with instant messaging use, while post-secondary education was associated with face-to-face (aPR 1.10), video call (aPR 1.79), and email (aPR 2.76) communications (all p &le; 0.03). Each ICT sharing method used was associated with a higher likelihood of both reported benefits (aPRs 1.26 and 1.52), better family communication quality and family well-being (adjusted &beta;s 0.43 and 0.30) (all p &le; 0.001). We have first shown that COVID-19 information sharing in families using both traditional methods and ICTs, and using more types of methods, was associated with perceived benefits and better family communication quality and well-being amidst the pandemic. Sociodemographic differences in COVID-19 information sharing using ICTs were observed. Digital training may help enhance social connections and promote family well-being

Longitudinal relations of perceived availability of neighborhood sport facilities with physical activity in adolescents: an analysis of potential moderators

Background Little is known about the longitudinal relations of environment attributes and leisure-time physical activity (PA) in adolescents, and the moderating effects of individual characteristics. This study examined the longitudinal association of the perceived availability of neighborhood sport facilities with leisure-time PA, and the potential moderating effects of age, past PA behavior, and weight status in adolescents. Methods Among 20,933 follow-up subjects (60.9% of 34,369 baseline subjects), 9993 from 32 Hong Kong secondary schools were successfully matched with baseline (mean duration 16 months; SD 1.7) and had complete information. At baseline and follow-up, respondents reported their leisure-time PA, weight, height, and the presence of sport facilities in the neighborhood. Results Increased perceived availability of sport facilities from baseline to follow-up predicted more leisure-time PA at follow-up (&beta; = 1.029; 95% CI: 1.011&ndash;1.047) overall. This effect was modified by baseline PA, with a significant effect observed only among those who had engaged in leisure-time PA more than 3 times a week. Conclusions Increasing awareness of neighborhood sport facilities or building more such facilities may help active adolescents maintain or increase their leisure-time PA. However, more comprehensive multilevel interventions that aim at enhancing potential social, personal, and environmental PA-related factors may be needed to motivate inactive adolescents

Adolescents’ physical activity : competition between perceived neighborhood sport facilities and home media resources

Objective. To examine the independent, competing, and interactive effects of perceived availability of specific types of media in the home and neighborhood sport facilities on adolescents&rsquo; leisure-time physical activity (PA). Methods. Survey data from 34 369 students in 42 Hong Kong secondary schools were collected (2006&ndash;07). Respondents reported moderate-to-vigorous leisure-time PA, presence of sport facilities in the neighborhood and of media equipment in the home. Being sufficiently physically active was defined as engaging in at least 30 minutes of non-school leisure-time PA on a daily basis. Logistic regression and post-estimation linear combinations of regression coefficients were used to examine the independent and competing effects of sport facilities and media equipment on leisure-time PA. Results. Perceived availability of sport facilities was positively (ORboys = 1.17; ORgirls = 1.26), and that of computer/Internet negatively (ORboys = 0.48; ORgirls = 0.41), associated with being sufficiently active. A significant positive association between video game console and being sufficiently active was found in girls (ORgirls = 1.19) but not in boys. Compared with adolescents without sport facilities and media equipment, those who reported sport facilities only were more likely to be physically active (ORboys = 1.26; ORgirls = 1.34), while those who additionally reported computer/Internet were less likely to be physically active (ORboys = 0.60; ORgirls = 0.54). Conclusions. Perceived availability of sport facilities in the neighborhood may positively impact on adolescents&rsquo; level of physical activity. However, having computer/Internet may cancel out the effects of active opportunities in the neighborhood. This suggests that physical activity programs for adolescents need to consider limiting the access to computer-mediated communication as an important intervention component

Data_Sheet_1_Association of family wellbeing with forwarding and verifying COVID-19-related information, and mediation of family communication quality.docx

ObjectiveWe assessed the associations of family wellbeing with verifying and subsequently forwarding COVID-19-related information to family members and the mediating effect of the quality of family communication on these associations among Chinese adults in Hong Kong.MethodsUnder the Jockey Club SMART Family-Link Project, we conducted an online population-based survey, using Family wellbeing Scale and questions related to the family communication quality and forwarding and verifying COVID-19 information. Data were collected from 4,891 adults in May 2020. Prevalence estimates of forwarding and verifying COVID-19 information were weighted by sex, age, and education of the general population, and their associations with family wellbeing (ranged 0–10) were analyzed using generalized linear models with mutual adjustment. Their interactive effects on family wellbeing and the mediating effects of family communication quality were examined.ResultsIn total, 53.9% of respondents usually/always forwarded COVID-19 information related to their family, 68.7% usually/always verified it before forwarding, and 40.9% did both. Greater family wellbeing was associated with usually/always forwarding [adjusted β (95% CI): 0.82 (0.72–0.92)] and usually/always verifying [0.43 (0.32–0.55)] (both P ConclusionForwarding COVID-19 information to family, verifying such information, and especially doing both, were associated with greater family wellbeing, being strongly mediated by the quality of family communication. Individuals should be encouraged to verify COVID-19-related information before forwarding it to family members amidst the COVID-19 pandemic.</p
