Abstract: Most studies that link neighbourhoods to disease outcomes have represented neighbourhoods as area-level socioeconomic status. Where objective contextual attributes of urban environments have been measured, few studies of food availability have evaluated mortality as an outcome. We sought to estimate associations between the availability of fast-food restaurants (FFR), fruit and vegetable stores (FVS), and cardiovascular mortality in an urban area. Food business data were extracted from a validated commercial database containing all businesses and services in the Montréal Census Metropolitan Area (MCMA). Mortality data (1999-2003) were obtained for the MCMA (3.4 million residents). Directly standardised mortality rates for cardiovascular deaths (n = 30,388) and non-cardiovascular deaths (all causes - cardiovascular deaths) (n = 91,132) and FFR and FVS densities (n/km²) were analysed for 845 census tracts. Generalised additive models and generalised linear models were used to analyse food source-mortality relationships. FVS density was not associated with cardiovascular or non-cardiovascular mortality (relative risk (RR) = 1.02, 95% confidence interval (CI): 0.76, 1.36, and RR = 1.14, 95% CI: 0.87, 1.50, respectively). Higher FFR density was associated with mortality in bivariate and multivariable analyses. Relative risks of death (95% CI) per 10% increase in FFR density were similar for both cardiovascular and non-cardiovascular mortality: 1.39 (1.19, 1.63) and 1.36 (1.18, 1.57), respectively, accounting for socio-demographic covariates. FFR density is associated with cardiovascular mortality but this relationship is no different in magnitude than that for non-cardiovascular mortality. These results together with null associations between FVS density and mortality do not support a major role for food source availability in cardiovascular outcomes.

Abstract: This study assessed relationships between built environmental exposures measured within components of in idual activity spaces (i.e., travel origins, destinations and paths in-between), and use of active transportation in a metropolitan setting. In iduals (n=37,165) were categorised as using active or sedentary transportation based on travel survey data. Generalised Estimating Equations analysis was used to test relationships with active transportation. Strength and significance of relationships between exposures and active transportation varied for different components of the activity space. Associations were strongest when including travel paths in expression of the built environment. Land use mix and greenness were negatively related to active transportation.

Abstract: Local fast-food environments have been increasingly linked to obesity and related outcomes. In iduals who are more sensitive to reward-related cues might be more responsive to such environments. This study aimed to assess the moderating role of sensitivity to reward on the relation between residential fast-food restaurant exposure and fast-food consumption. Four hundred fifteen in iduals (49.6% men mean age: 34.7 y) were s led from 7 Montreal census tracts stratified by socioeconomic status and French/English language. The frequency of fast-food restaurant visits in the previous week was self-reported. Sensitivity to reward was self-reported by using the Behavioral Activation System (BAS) scale. Fast-food restaurant exposure within 500 m of the participants' residence was determined by using a Geographic Information System. Main and interactive effects of the BAS and fast-food restaurant exposure on fast-food consumption were tested with logistic regression models that accounted for clustering of observations and participants' age, sex, education, and household income. Regression results showed a significant interaction between BAS and fast-food restaurant exposure (P < 0.001). Analysis of BAS tertiles indicated that the association between neighborhood fast-food restaurant exposure and consumption was positive for the highest tertile (odds ratio: 1.49 95% CI: 1.20, 1.84 P < 0.001) but null for the intermediate (odds ratio: 1.03 95% CI: 0.80, 1.34 P = 0.81) and lowest (odds ratio: 0.84 95% CI: 0.51, 1.37 P = 0.49) tertiles. Reward-sensitive in iduals may be more responsive to unhealthful cues in their immediate environment.

Abstract: Although the needs of the bereaved have been identified widely in the literature, how these needs translate into meaningful, appropriate, and client-centered programs needs further exploration. The application of receptivity to support is a critical factor in participation by the bereaved in palliative care bereavement programs. Receptivity is a complex multifactorial phenomenon influenced by internal and external factors that ultimately influences engagement in psychosocial support in bereavement. This study explored factors that influence receptivity to bereavement support from palliative care services in rural, regional, and remote Western Australia. The study comprised a qualitative descriptive research design using semistructured interviews with 24 bereaved in iduals, nine palliative care health professionals, and four Aboriginal Health Professionals. Participants were recruited via palliative care services in country Western Australia. Interviews were transcribed verbatim and thematically analyzed. Findings revealed that a range of in idual, social, and geographical factors influence receptivity to bereavement support and can impact on utilization of bereavement support services. Receptivity provides a frame of reference to enhance understanding of factors influencing engagement in psychosocial support in bereavement. Receptivity promotes a shift of service provider perspectives of effective supportive care to consumer-centric reasons for engagement.

Abstract: Sleep is important for the physical, social and mental well-being of both children and adults. Over the years, there has been a general presumption that sleep will inevitably decline with the increase in technology and a busy 24-hour modern lifestyle. This narrative review discusses the empirical evidence for secular trends in sleep duration and the implications of these trends.

Abstract: A systematic review was conducted, following PRISMA guidelines, to examine the application of finite mixture models (FMMs) in the study of neighbourhoods and health. Two reviewers screened 814-studies identified through database searches and citation tracking. Data were extracted from 19-studies that met the inclusion criteria, and a risk of bias analysis undertaken. Data were synthesised narratively, with a focus on methodological issues idiosyncratic to FMMs. Motivated by a desire to account for neighbourhood heterogeneity, studies sought to identify meaningful neighbourhood-level typologies that explained the distributional nature of health outcomes. Neighbourhood-centred applications of FMMs were promising but there remains scope for advancement. Research-based recommendations are outlined to strengthen prospective neighbourhood-centred studies applying FMMs.

Abstract: Sleep is essential for children's health and well-being. Characteristics of children's sleep such as sleep duration, timing, quality and variability are increasingly being associated with a wide range of health outcomes. The purpose of this study is to conduct a meta-review (systematic review of systematic reviews) to examine the relationship between sleep and health in children. A systematic search of four electronic databases (Medline, PsychInfo, Scopus, and Embase) was conducted to identify systematic reviews that examine the association between characteristics of children's sleep and health. Key findings, as well as areas in need of further research were synthesised descriptively. A total of 39 systematic reviews were identified for inclusion, covering areas of cognition, psychosocial health, cardiometabolic health, adiposity and other outcomes such as musculoskeletal pain. There is substantial and consistent evidence relating sleep duration to adiposity and emotional outcomes. The relationships between sleep quality and timing and blood lipids and glycaemic control merit further research. Links between sleep and metabolic syndrome in children appear to be weak and inconsistent. Key areas identified in need for further research included studies that objectively assess children's sleep and move beyond cross-sectional study designs and consider characteristics of sleep other than duration. It was also noted that covariates applied across studies varied considerably and the issue of residual confounding was raised in a number of reviews. Lastly, all reviews reported studies adopted a traditional approach of examining only one aspect of children's sleep. Systematic reviews support the notion that sleep is important for children's health. However, further studies that objectively assess sleep and consider characteristics of sleep other than duration and outcomes other than adiposity are needed. An understanding of sleep as a multidimensional construct and as a component of the 24-h d, is also needed to better understand the relationship between sleep and health in children.

Abstract: Food- and activity-related establishments are increasingly viewed as neighbourhood resources that potentially condition health-related behaviour. The primary objective of the current study was to establish, using ground truthing (on-site verification), the validity of measures of availability of food stores and physical activity establishments that were obtained from commercial database and Internet searches. A secondary objective was to examine differences in validity results according to neighbourhood characteristics and commercial establishment categories. Lists of food stores and physical activity-related establishments in 12 census tracts within the Montreal metropolitan region were compiled using a commercial database (n = 171 establishments) and Internet search engines (n = 123 establishments). Ground truthing through field observations was performed to assess the presence of listed establishments and identify those absent. Percentage agreement, sensitivity (proportion of establishments found in the field that were listed), and positive predictive value (proportion of listed establishments found in the field) were calculated and contrasted according to data sources, census tracts characteristics, and establishment categories. Agreement with field observations was good (0.73) for the commercial list, and moderate (0.60) for the Internet-based list. The commercial list was superior to the Internet-based list for correctly listing establishments present in the field (sensitivity), but slightly inferior in terms of the likelihood that a listed establishment was present in the field (positive predictive value). Agreement was higher for food stores than for activity-related establishments. Commercial data sources may provide a valid alternative to field observations and could prove a valuable tool in the evaluation of commercial environments relevant to eating behaviour. In contrast, this study did not find strong evidence in support of commercial and Internet data sources to represent neighbourhood opportunities for active lifestyle.

Abstract: Stroke is a leading cause of death and disability. It is a complex and largely heterogeneous condition. Prognosis for variations in impairment and recovery following stroke continues to be challenging and inaccurate, highlighting the need to examine the influence of other currently unknown variables to better predict and understand interin idual differences in stroke impairment and recovery. The concept of “cognitive reserve,” a feature of brain function said to moderate the relationship between brain pathology and clinical outcomes, might provide a partial explanation. This review discusses the potential significance of cognitive reserve in the context of stroke, with reference to reduced burden of disability poststroke, health promotion, intervention and secondary prevention of cognitive impairment, ease and challenges of translation into clinical practice, prognosis and prediction of recovery, and clinical decisions and trial stratification. Discussions from the review aim to encourage stroke clinicians and researchers to better consider the role of premorbid, lifestyle-related variables, such as cognitive reserve, in facilitating successful neurological outcomes and recovery following stroke.

Abstract: The present study sought to investigate the associations of total n -3 fatty acid and SFA intakes with insulin resistance in a Canadian First Nation s le at risk for type 2 diabetes. Fasting values for glucose and insulin were used to estimate insulin resistance by homeostasis model assessment (HOMA-IR). Intakes of n -3 fatty acids and SFA were computed from dietary food and drink data obtained using 3 d food records. Associations between HOMA-IR and dietary n -3 and SFA consumption were tested using linear regression models accounting for age, sex, community, education, physical activity, waist circumference, fibre, protein and carbohydrate intakes, and HDL-cholesterol and TAG concentrations. Rural Okanagan region of British Columbia, Canada. On-reserve First Nation in iduals (Interior Salishan) aged 18 years and over, recruited for community-based diabetes screening and determined to be normoglycaemic ( n 126). HOMA-IR was negatively associated with dietary n -3 fatty acid intake ( β = −0·22 95 % CI −0·39, −0·04 P = 0·016) and positively associated with dietary SFA intake ( β = 0·34 95 % CI 0·15, 0·53 P = 0·0 0 1). Intake of dietary n -3 fatty acids may be protective against whereas SFA intake may promote insulin resistance in this high-risk Canadian First Nation s le. Reduced dietary SFA intake and greater n -3 fatty acid intake may assist the prevention of glycaemic disease among First Nations peoples. More rigorous, controlled trials are required to test whether dietary supplementation with n -3 fatty acids in natural or supplement-based form might reduce diabetes risk in high-risk aboriginal groups.

Abstract: The Dyspnoea-12 (D-12) and Multidimensional Dyspnea Profile (MDP) were specifically developed for assessment of multiple sensations of breathlessness. This systematic review aimed to identify the use and measurement properties of the D-12 and MDP across populations, settings and languages. Electronic databases were searched for primary studies (2008-2020) reporting use of the D-12 or MDP in adults. Two independent reviewers completed screening and data extraction. Study and participant characteristics, instrument use, reported scores and minimal clinical important differences (MCID) were evaluated. Data on internal consistency (Cronbach's α) and test-retest reliability (intraclass correlation coefficient, ICC) were pooled using random effects models between settings and languages. A total 75 publications reported use of D-12 (n = 35), MDP (n = 37) or both (n = 3), reflecting 16 chronic conditions. Synthesis confirmed two factor structure, internal consistency (Cronbach's α mean, 95% CI: D-12 Total = 0.93, 0.91-0.94 MDP Immediate Perception [IP] = 0.88, 0.85-0.90 MDP Emotional Response [ER] = 0.86, 0.82-0.89) and 14 day test-rest reliability (ICC: D-12 Total = 0.91, 0.88-0.94 MDP IP = 0.85, 0.70-0.93 MDP ER = 0.84, 0.73-0.90) across settings and languages. MCID estimates for clinical interventions ranged between -3 and -6 points (D-12 Total) with small variability in scores over 2 weeks (D-12 Total 2.8 (95% CI: 2.0 to 3.7), MDP-A1 0.8 (0.6 to 1.1) and six months (D-12 Total 2.9 (2.0 to 3.7), MDP-A1 0.8 (0.6 to 1.1)). D-12 and MDP are widely used, reliable, valid and responsive across various chronic conditions, settings and languages, and could be considered standard instruments for measuring dimensions of breathlessness in international trials.

Abstract: Hypertriglyceridemic waist (HTgW) is predictive of cardiovascular disease. The HTgW relationship with diabetes is little studied. This study analysed data from diabetes and cardiovascular risk factor screening programmes in remote Indigenous Australian settlements. Elevated waist girth (EW) was defined as ≥90 cm for men (n = 1134) or ≥80 cm for women (n = 1313). Hypertriglyceridemia (ETg) was defined as ≥1.7 mmol/L. Diabetes was defined as fasting plasma glucose ≥7.0 mmol/L. Body mass index (BMI) was categorised as 25.0 kg/m(2). Logistic regression was used to analyse the odds of newly-diagnosed diabetes for in iduals with either HTgW, ETg or EW, relative to in iduals with values below cut-offs. The prevalence of HTgW was 33.2% for men and 34.8% for women. Accounting for age-group and gender, newly-diagnosed diabetes was associated (odds ratio (OR) (95% confidence interval)) with HTgW: 9.6 (6.6, 13.8). The relationship remained strong after accounting for the covariates BMI and smoking (OR = 4.9 (2.7, 8.8)). In BMI-stratified analyses the strongest odds were observed for the lowest category (<22 kg/m(2): OR = 12.9 (4.0, 41.7)). HTgW has a high prevalence and is associated with newly-diagnosed diabetes in Indigenous people, particularly those with BMI <22 kg/m(2), whom clinicians might not normally consider for screening.

Abstract: Evidence exists of an increasing prevalence of chronic conditions within developed and developing nations, notably for priority population groups. The need for the collection of geospatial data to monitor the health impact of rapid social-environmental and economic changes occurring in these countries is being increasingly recognized. Rigorous accuracy assessment of such geospatial data is required to enable error estimation, and ultimately, data utility for exploring population health. This research outlines findings from a field-based evaluation exercise of the SOMAARTH DDESS geospatial-health platform. Participatory-based mixed methods have been employed within Palwal-India to capture villager perspectives on built infrastructure across 51 villages. This study, conducted in 2013, included an assessment of data element position and attribute accuracy undertaken in six villages, documenting mapping errors and land parcel changes. Descriptive analyses of 5.1% ( n = 455) of land parcels highlighted some discrepancies in position (6.4%) and attribute (4.2%) accuracy, and land parcel changes (17.4%). Furthermore, the evaluation led to a refinement of the existing geospatial health platform incorporating ground-truthed reflections from the participatory field exercise. The evaluation of geospatial data accuracies contributes to understandings on global public health surveillance systems, outlining the need to systematically consider assessment of environmental features in relation to lifestyle-related diseases.

Abstract: Walkability of residential environments has been associated with more walking. Given the health benefits of walking, it is expected that people living in locations with higher measured walkability should have a lower risk of cardiometabolic diseases. This study tested the hypothesis that higher walkability was associated with a lower cardiometabolic risk (CMR) for two administrative spatial units and three road buffers. Data were from the North West Adelaide Health Study first wave of data collected between 2000 and 2003. CMR was expressed as a cumulative sum of six clinical risk markers, selected to reflect components of the metabolic syndrome. Walkability was based on an established methodology and operationalised as dwelling density, intersection density, land-use mix and retail footprint. Walkability was associated with lower CMR for the three road buffer representations of the built environment but not for the two administrative spatial units. This may indicate a limitation in the use of administrative spatial units for analyses of walkability and health outcomes.

Abstract: In patients with COPD, psychological interventions usually target generalized anxiety and depression rather than the sensation of breathlessness. The objectives of this pilot study were to develop and implement a cognitive behavioral therapy (CBT) program specific to the perceptual experience of breathlessness, identify practical issues in the study protocol, and estimate beneficial effects of combining the CBT program with comprehensive pulmonary rehabilitation. The CBT program for the sensation of breathlessness (Breathing: Recognize sensations, Explore thoughts and beliefs, Validate thoughts as useful or harmful, Evolve and change behavior [BREVE]) was developed as a sequential series of 8 modules enabling it to be embedded within an 8-week comprehensive pulmonary rehabilitation program. When appropriate, outcomes from the pilot group (comprehensive pulmonary rehabilitation program + BREVE) were compared with those from a retrospective control group (comprehensive pulmonary rehabilitation program only). Outcomes included feedback provided by pilot study subjects, sensation of breathlessness (volunteered and endorsed descriptors of breathlessness), 6-min walk distance (6MWD), and St George Respiratory Questionnaire (SGRQ) total score. Within-group analyses were undertaken for descriptors of breathlessness (the McNemar test), whereas between-group analyses (repeated-measures analysis of variance, effect-size comparison) were conducted for the 6MWD and SGRQ total score. Pilot (n = 11) and control (n = 58) groups were not significantly different at baseline. Feedback indicated that the program structure and content were positively received. No significant changes were evident for the sensation of breathlessness or the SGRQ score (< 4 points). The 6MWD improved significantly in both groups, with the pilot group demonstrating greater gains compared with the control group (mean change of 57 m and effect size of 0.73 vs mean change of 27 m and effect size of 0.23 between groups, P = .03, effect size of 0.69). The CBT program for the perceptual experience of breathlessness was feasible and well accepted by subjects, although the protocol raised a number of methodological limitations warranting modification. A larger randomized controlled trial is needed to determine the effectiveness and longer-term outcomes.

Abstract: Sleep is important for the physical, social and mental well-being of both children and adults. In this paper, we discuss the need to consider sleep as a multidimensional construct and as a component of total 24-hour activity. First, we make a case for considering sleep as a multidimensional construct, whereby all characteristics of sleep (including duration, quality, timing, and variability) and their links with health are examined. Second, we argue that sleep should also be conceptualized as part of the daily spectrum of time-use, along with other types of activity. We propose novel statistical models, in particular compositional data analysis (CoDA), as appropriate analytical methods for a new sleep paradigm.

Abstract: Few studies have examined the contribution of life-course factors in explaining familial aggregation of chronic lung conditions. Using data from the 1958 British Birth Cohort, a life-course approach was used to examine whether, and how, exposure to risk factors through one's life explained the association between parental respiratory disease history and symptomatic airflow obstruction (AO). Cohort participants (n=6212) were characterised in terms of parental respiratory disease history and symptomatic AO at 45 years. Life-course factors ( e.g. smoking, asthma and early-life factors) were operationalised as life period-specific and cumulative measures. Logistic regression and path analytic models predicting symptomatic AO adjusted for parental respiratory disease history were used to test different life-course models (critical period, accumulation- and chain-of-risks models). While some life-course factors ( e.g. childhood passive smoking and occupational exposure) were in idually associated with parental respiratory disease history and symptomatic AO, asthma (OR 6.44, 95% CI 5.01–8.27) and persistent smoking in adulthood (OR 5.42, 95% CI 4.19–7.01) had greater impact on the association between parental respiratory disease history and symptomatic AO. A critical period model provided a better model fit compared with an accumulation-of-risk model and explained 57% of the effect of parental respiratory disease history on symptomatic AO. Adulthood asthma and smoking status explained around half of the effect of parental respiratory disease history on chronic obstructive pulmonary disease. Beyond smoking history, the combination of parental respiratory disease history and adulthood asthma may provide an opportunity for early diagnosis and intervention.

Abstract: Research on traumatic stress has focused largely on in idual risk factors. A more thorough understanding of risk factors may require investigation of the contribution of neighborhood context, such as the associations between perceived neighbourhood disorder and social cohesion with reported trauma exposure (yes/no) and posttraumatic stress disorder (PTSD) diagnostic status (past-year PTSD, remitted). To examine these associations, we used a cross-sectional analysis of an epidemiological catchment area survey (N = 2,433). Visible cues, indicating a lack of order and social control in the community (neighbourhood disorder), were associated with increased trauma exposure (adjusted odds ratio [AOR] = 1.21, 95% confidence interval [CI] [1.12, 1.31]). For trauma-exposed in iduals, neighbourhood disorder was associated with greater odds of lifetime PTSD (AOR = 1.38, 95% CI [1.10, 1.75]), and the willingness of residents who realize common values to intervene for the common good (social cohesion), was associated with lower likelihood of past-year PTSD (AOR = 0.64, 95% CI [0.42, 0.97]). For participants with a lifetime diagnosis of PTSD (including past-year), increased social cohesion was associated with higher odds of remission (AOR = 2.59, 95% CI [1.55, 4.30]). Environmental contexts play a role in the development and progression of PTSD. As such, traumatic stress outcomes may be better understood through a perspective that integrates in idual and contextual risk factors.

Abstract: The health inequalities experienced by Aboriginal and Torres Strait Islander Australians are well documented but there are few empirical data outlining the burden, consequences, experience and expression of depressive illness. This paper seeks to address the lack of accessible, culturally specific measures of psychosocial stress, depression or quality of life developed for, and validated within, this population. Building on an extensive qualitative phase of research, a psychosocial questionnaire comprising novel and adapted scales was developed and piloted with 189 Aboriginal men across urban and remote settings in central Australia. With a view to refining this tool for future use, its underlying structure was assessed using exploratory factor analysis, and the predictive ability of the emergent psychosocial constructs assessed with respect to depressive symptomatology. The latent structure of the psychosocial questionnaire was conceptually aligned with the components of the a priori model on which the questionnaire was based. Regression modelling indicated that depressive symptoms were driven by a sense of injury and chronic stress and had a non-linear association with socioeconomic position. This represents the first community-based survey of psychosocial stress and depression in Aboriginal men. It provides both knowledge of, and an appropriate process for, the further development of psychometric tools, including quality of life, in this population. Further research with larger and more erse s les of Aboriginal people is required to refine the measurement of key constructs such as chronic stress, socioeconomic position, social support and connectedness. The further refinement, validation against criterion-based methods and incorporation within primary care services is essential.
