"In small places, close to home": Urban environmental impacts on child rights across four global cities.

Urban environments influence child behaviours, exposures and experiences and may affect health, development, achievement and realization of fundamental human rights. We examined the status of eleven UN Convention on the Rights of the Child articles, in a multi-case study across four global cities. Within all study cities, children experienced unequal exposure to urban environmental risks and amenities. Many violations of child rights are related to car-based transportation systems and further challenged by pressures on urban systems from rapid population increases in the context of climate change. A child rights framework provides principles for a collective, multi-sectoral re-imagination of urban environments that support the human rights of all citizens.

Neighborhood infrastructure-related risk factors and non-communicable diseases: a systematic meta-review.

BACKGROUND: With rapid urbanization, the urban environment, especially the neighborhood environment, has received increasing global attention. However, a comprehensive overview of the association between neighborhood risk factors and human health remains unclear due to the large number of neighborhood risk factor-human health outcome pairs. METHOD: On the basis of a whole year of panel discussions, we first obtained a list of 5 neighborhood domains, containing 33 uniformly defined neighborhood risk factors. We only focused on neighborhood infrastructure-related risk factors with the potential for spatial interventions through urban design tools. Subsequently, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic meta-review of 17 infrastructure-related risk factors of the 33 neighborhood risk factors (e.g., green and blue spaces, proximity to major roads, and proximity to landfills) was conducted using four databases, Web of Science, PubMed, OVID, and Cochrane Library, from January 2000 to May 2021, and corresponding evidence for non-communicable diseases (NCDs) was synthesized. The review quality was assessed according to the A MeaSurement Tool to Assess Systematic Reviews (AMSTAR) standard. RESULTS: Thirty-three moderate-and high-quality reviews were included in the analysis. Thirteen major NCD outcomes were found to be associated with neighborhood infrastructure-related risk factors. Green and blue spaces or walkability had protective effects on human health. In contrast, proximity to major roads, industry, and landfills posed serious threats to human health. Inconsistent results were obtained for four neighborhood risk factors: facilities for physical and leisure activities, accessibility to infrastructure providing unhealthy food, proximity to industry, and proximity to major roads. CONCLUSIONS: This meta-review presents a comprehensive overview of the effects of neighborhood infrastructure-related risk factors on NCDs. Findings on the risk factors with strong evidence can help improve healthy city guidelines and promote urban sustainability. In addition, the unknown or uncertain association between many neighborhood risk factors and certain types of NCDs requires further research.

Influence of Neighborhood Built Environments on the Outdoor Free Play of Young Children: a Systematic, Mixed-Studies Review and Thematic Synthesis.

Urban environments shape early childhood exposures, experiences, and health behaviors, including outdoor free play, influencing the physical, cognitive, social, and emotional development of young children. We examined evidence for urban or suburban built environment influences on outdoor free play in 0-6-year-olds, considering potential differences across gender, culture, and geography. We systematically searched seven literature databases for relevant qualitative, quantitative, and mixed methods studies: of 5740 unique studies, 53 met inclusion criteria. We assessed methodological quality and thematically synthesized findings from included studies. Three broad themes, features of spaces for play, routes, and social factors intersected to influence the availability, accessibility, and acceptability of neighborhoods for young children's outdoor free play across diverse cultural and geographic contexts. Proximity to formal or informal space for play, protection from traffic, pedestrian environment, green and natural environments, and opportunity for social connection supported outdoor free play. Family and community social context influenced perceptions of and use of space; however, we did not find consistent, gendered differences in built environment correlates of outdoor free play. Across diverse contexts, playable neighborhoods for young children provided nearby space for play, engaging routes protected from traffic and facilitated frequent interaction between people, nature, and structures.

Characterisation of urban environment and activity across space and time using street images and deep learning in Accra.

The urban environment influences human health, safety and wellbeing. Cities in Africa are growing faster than other regions but have limited data to guide urban planning and policies. Our aim was to use smart sensing and analytics to characterise the spatial patterns and temporal dynamics of features of the urban environment relevant for health, liveability, safety and sustainability. We collected a novel dataset of 2.1 million time-lapsed day and night images at 145 representative locations throughout the Metropolis of Accra, Ghana. We manually labelled a subset of 1,250 images for 20 contextually relevant objects and used transfer learning with data augmentation to retrain a convolutional neural network to detect them in the remaining images. We identified 23.5 million instances of these objects including 9.66 million instances of persons (41% of all objects), followed by cars (4.19 million, 18%), umbrellas (3.00 million, 13%), and informally operated minibuses known as tro tros (2.94 million, 13%). People, large vehicles and market-related objects were most common in the commercial core and densely populated informal neighbourhoods, while refuse and animals were most observed in the peripheries. The daily variability of objects was smallest in densely populated settlements and largest in the commercial centre. Our novel data and methodology shows that smart sensing and analytics can inform planning and policy decisions for making cities more liveable, equitable, sustainable and healthy.

Neighbourhood, Built Environment and Children's Outdoor Play Spaces in Urban Ghana: Review of Policies and Challenges.

Although a great deal of research work has been done by social scientists on walkability and playability, the focus to a large extent has been on the global north. Research work on the urban built environment and children's play has not engaged Africa in general and Ghana in particular. More importantly, there is limited evidence of policies in terms of community-based practices and governmental policies and programmes for the promotion of play. The limited effort in promoting physical activities have to a large extent focused on walkability, yet evidence to date indicates that walking only constitutes a small proportion of the physical activities of children. This is against the backdrop of growing urbanization and the increasing reported incidence of sedentary lifestyles, less physical activity and obesity among children and the youth. Our main objective in this paper is to contribute to the literature on Ghana, and by extension Sub-Saharan Africa, by examining the extent to which playability features in city and national policies and strategies in urban Ghana. We conclude that while there is dearth of public policies on children's play, with the situation in communities compounded by weak city government capacity to plan, implement and enforce development control to protect open spaces for children's play and recreational purposes. The paper recommends a change in policy and practice on creating spaces in urban built-environments for children's play in urban Ghana.

Building a Methodological Foundation for Impactful Urban Planetary Health Science.

Anthropogenic environmental change will heavily impact cities, yet associated health risks will depend significantly on decisions made by urban leaders across a wide range of non-health sectors, including transport, energy, housing, basic urban services, and others. A subset of planetary health researchers focus on understanding the urban health impacts of global environmental change, and how these vary globally and within cities. Such researchers increasingly adopt collaborative transdisciplinary approaches to engage policy-makers, private citizens, and other actors in identifying and evaluating potential policy solutions that will reduce environmental impacts in ways that simultaneously promote health, equity, and/or local economies-in other words, maximising 'co-benefits'. This report presents observations from a participatory workshop focused on challenges and opportunities for urban planetary health research. The workshop, held at the 16th International Conference on Urban Health (ICUH) in Xiamen, China, in November 2019, brought together 49 participants and covered topics related to collaboration, data, and research impact. It featured research projects funded by the Wellcome Trust's Our Planet Our Health (OPOH) programme. This report aims to concisely summarise and disseminate participants' collective contributions to current methodological practice in urban planetary health research.

Perinatal health care providers' approaches to recommending and providing pertussis vaccination in pregnancy: a qualitative study.

BACKGROUND: In 2018, the Canadian National Advisory Committee on Immunization and the Society of Obstetricians and Gynaecologists of Canada recommended a single dose of tetanus toxoid, reduced diphtheria toxoid and reduced acellular pertussis (Tdap) vaccine in every pregnancy. To understand how perinatal health care providers in Canada are translating recent recommendations for universal antenatal Tdap vaccine into routine clinical practice, we examined health care providers' perceptions of what influences their ability to recommend and provide Tdap vaccine consistently to pregnant women. METHODS: Between June 2018 and July 2019, we conducted semistructured telephone interviews with perinatal health care providers (nurses, midwives, family physicians and obstetricians) from 5 provinces (British Columbia, Manitoba, Ontario, Quebec and Nova Scotia) representing diverse educational experiences, practice settings and models of care. We analyzed the data using interpretive description. RESULTS: We interviewed 44 perinatal health care providers (13 family physicians, 12 midwives, 10 obstetricians and 9 nurses) practising in a variety of settings. Health care providers' ability to recommend and provide antenatal Tdap vaccine was strongly influenced by structural constraints in the Canadian perinatal health care system. The participants' clinical training varied, which resulted in different knowledge and practices. Participants felt hindered by a lack of lay information resources. Consistent and convenient vaccine access was perceived to be key to promoting confidence and encouraging uptake, yet antenatal Tdap vaccine was not easily accessible for all women. INTERPRETATION: Our findings suggest that Canada's fragmented health care model has a detrimental effect on health care providers' ability to recommend and ensure access to antenatal Tdap vaccine. Lessons from this study are pertinent to the implementation of successful pertussis vaccine programs and future pregnancy vaccination initiatives.

Evaluation of an Information Pamphlet for Women Considering Epidural Analgesia in Labour.

OBJECTIVE: This study sought to assess change in knowledge and preference for epidural use associated with use of an information pamphlet and to explore women's decision-making and information needs regarding pain relief in labour. METHODS: Six focus groups with women who were pregnant or had given birth during the past 12 months were conducted in three northern communities in British Columbia. Following completion of a 10-item knowledge pretest, women were randomly assigned to read either a short version or a detailed version of the pamphlet and then complete a post-test. After reading the alternate pamphlet they participated in a moderated discussion. Pretest and post-test knowledge scores were compared, and a thematic analysis of focus group data was conducted. RESULTS: Knowledge scores increased (2.12 points out of a possible total of 10; standard deviation 2.38; 95% CI 1.38 to 2.87). There was no difference in knowledge change or epidural preferences according to which version participants read first. Women preferred the detailed version and indicated that its information was more balanced. Four themes related to decision-making and information needs arose from the focus groups: making an informed choice, being open-minded, wanting comprehensive information, and experiencing pressure to have/not have an epidural. CONCLUSION: An illustrated information pamphlet can significantly increase women's knowledge of benefits and risks of epidural analgesia, but it is not associated with change of preference. Women prefer to receive comprehensive information prenatally to support informed choices in labour.

SmartMom Text Messaging for Prenatal Education: A Qualitative Focus Group Study to Explore Canadian Women's Perceptions.

BACKGROUND: We engaged Canadian women in the development of a prenatal education program delivered via one-way text messaging called SmartMom. SmartMom is the first peer-reviewed, evidence-based mHealth program for prenatal education in Canada and the first to be endorsed by the Society of Obstetricians and Gynaecologists of Canada. OBJECTIVE: To explore women's preferences for a prenatal education program by text messaging. METHODS: We conducted a qualitative focus group study in three Canadian communities in the Northern Health Authority. Women completed a demographic questionnaire, participated in a guided discussion about their pregnancy information-seeking behavior, reviewed a printed copy of the SmartMom text messages, and then engaged in a moderated discussion about their perceptions of the usability of the SmartMom program. Open-ended questions explored women's perceptions regarding the message content, acceptability of receiving information by text message, positive health behaviors they might engage in after receiving a message, modifiable program factors, and intention to use the program. Thematic analysis of transcribed audio recordings was undertaken and modifications were made to the SmartMom program based on these findings. RESULTS: A total of 40 women participated in seven focus groups in three rural northern communities. The vast majority had a mobile phone (39/40, 98%), used text messages "all the time" (28/40, 70%), and surfed the Internet on their phone (37/40, 93%). Participants perceived SmartMom to be highly acceptable and relevant. The text message modality reflected how participants currently sought pregnancy-related information and provided them with local information tailored to their gestational age, which they had not received through other pregnancy resources. Women recommended adding the opportunity to receive supplemental streams of messages tailored to their individual needs, for example, depression, pregnancy after previous cesarean, >35 years of age, new immigrants, and harm reduction for smoking and alcohol. CONCLUSIONS: This formative qualitative evaluation provides evidence that a prenatal education program by text messaging, SmartMom, is acceptable to the end users. These findings support the usability of the SmartMom program at a population level and the development of an evaluation program exploring the effects of the text messages on adoption of health-promoting behaviors and maternal-child health outcomes.
