In recent years, obesity-related diseases have been on the rise globally resulting in major challenges for health systems and society as a whole. Emerging research in population health suggests that interventions targeting the built environment may help reduce the burden of obesity and type 2 diabetes. However, translation of the evidence on the built environment into effective policy and planning changes requires engagement and collaboration between multiple sectors and government agencies for designing neighborhoods that are more conducive to healthy and active living. In this study, we identified knowledge gaps and other barriers to evidence-based decision-making and policy development related to the built environment; as well as the infrastructure, processes, and mechanisms needed to drive policy changes in this area. We conducted a qualitative thematic analysis of data collected through consultations with a broad group of stakeholders (N = 42) from Southern Ontario, Canada, within various sectors (public health, urban planning, and transportation) and levels of government (federal, provincial, and municipalities). Relevant themes were classified based on the specific phase of the knowledge-to-action cycle (research, translation, and implementation) in which they were most closely aligned. We identified 5 themes including: 1) the need for policy-informed and actionable research (e.g. health economic analyses and policy evaluations); 2) impactful messaging that targets all relevant sectors to create the political will necessary to drive policy change; 3) common measures and tools to increase capacity for monitoring and surveillance of built environment changes; (4) intersectoral collaboration and alignment within and between levels of government to enable collective actions and provide mechanisms for sharing of resources and expertise, (5) aligning public and private sector priorities to generate public demand and support for community action; and, (6) solution-focused implementation of research that will be tailored to meet the needs of policymakers and planners. Additional research priorities and key policy and planning actions were also noted. Our research highlights the necessity of involving stakeholders in identifying inter-sectoral solutions to develop and translate actionable research on the built environment into effective policy and planning initiatives.

The global increase in obesity is a major contemporary health problem. The National Health and Nutrition Examination Survey estimated that 69% of US adults were overweight or obese in 2011-2012, whereas 35% met the definition of obesity, an increase in obesity prevalence from 15% in the late 1970s.^1,2 A parallel increase in diabetes prevalence among adults occurred during the latter half of this period, from less than 4% in 1990 to 8.3% in 2012.^3,4 Similar trends have been observed in Canada and other nations worldwide.^5,6

There is a consensus that interventions to prevent and treat childhood obesity should involve the family; however, the extent of the child's involvement has received little attention. The goal of the present study was to evaluate the relative efficacy of treating childhood obesity via a family-based health-centred intervention, targeting parents alonev. parents and obese children together. Thirty-two families with obese children of 6–11 years of age were randomised into groups, in which participants were provided for 6 months a comprehensive educational and behavioural programme for a healthy lifestyle. These groups differed in their main agent of change: parents-onlyv. the parents and the obese child. In both groups, parents were encouraged to foster authoritative parenting styles (parents are both firm and supportive; assume a leadership role in the environmental change with appropriate granting of child's autonomy). Only the intervention aimed at parents-only resulted in a significant reduction in the percentage overweight at the end of the programme (P=0·02) as well as at the 1-year follow-up meeting.The differences between groups at both times were significant (P<0·05). A greater reduction in food stimuli in the home (P<0·05) was noted in the parents-only group. In both groups, the parents' weight status did not change. Regression analysis shows that the level of attendance in sessions explained 28% of the variability in the children's weight status change, the treatment group explained another 10%, and the improvement in the obesogenic load explained 11% of the variability. These results suggest that omittingthe obese child from active participation in the health-centred programme may be beneficial for weight loss and for the promotion of a healthy lifestyle among obese children.

The design of suburban communities encourages car dependency and discourages walking, characteristics that have been implicated in the rise of obesity. Walkability measures have been developed to capture these features of urban built environments. Our objective was to examine the individual and combined associations of residential density and the presence of walkable destinations, two of the most commonly used and potentially modifiable components of walkability measures, with transportation, overweight, obesity, and diabetes. We examined associations between a previously published walkability measure and transportation behaviors and health outcomes in Toronto, Canada, a city of 2.6 million people in 2011. Data sources included the Canada census, a transportation survey, a national health survey and a validated administrative diabetes database. We depicted interactions between residential density and the availability of walkable destinations graphically and examined them statistically using general linear modeling. Individuals living in more walkable areas were more than twice as likely to walk, bicycle or use public transit and were significantly less likely to drive or own a vehicle compared with those living in less walkable areas. Individuals in less walkable areas were up to one-third more likely to be obese or to have diabetes. Residential density and the availability of walkable destinations were each significantly associated with transportation and health outcomes. The combination of high levels of both measures was associated with the highest levels of walking or bicycling (p<0.0001) and public transit use (p<0.0026) and the lowest levels of automobile trips (p<0.0001), and diabetes prevalence (p<0.0001). We conclude that both residential density and the availability of walkable destinations are good measures of urban walkability and can be recommended for use by policy-makers, planners and public health officials. In our setting, the combination of both factors provided additional explanatory power.

Background Prevalence rates of postpartum depression (PPD) are 10 to 20% among various populations. Little is known about the characteristics of PPD among populations experiencing cultural transition. This study aimed to assess PPD symptoms (PPDS) prevalence and to identify risk factors unique to Arab-Bedouin women in southern Israel. Methods The sample included 564 women who visited maternal and child health clinics. Sociodemographic characteristics were obtained using in-person interviews. PPDS were assessed using a validated Arabic translation of the Edinburgh Postnatal Depression Scale (EPDS). Prevalence of PPDS was estimated using the cut-off score of EPDS ≥10; a more stringent cut-off score of EPDS ≥13 was used to define women with moderate to severe PPDS. Results The prevalence of PPDS among women was 31%, of which 19.1% were assessed as having moderate to severe symptoms (EPDS ≥ 13). In a multivariate logistic regression, the variables associated with EPDS ≥10 were having an ill-infant odds ratio (OR) = 3.9, lack of husband's support (OR = 2.6), history of emotional problems (OR = 3.2), low income (OR = 1.6), low level of education (OR = 1.6), high marital conflicts (OR = 1.5), and an unplanned pregnancy (OR = 1.5). Conclusion In the generally understudied population of Arab-Bedouin women living in southern Israel, we found a high prevalence of PPDS. The unique risk factors described in our research can inform health care professionals in designing interventions for early detection and prevention of PPD.

Dietary patterns (DPs), usually established in adolescents, are important modifiable risk factors in the etiology of malnutrition and chronic diseases. This study aimed to identify DPs of adolescents and examine their associations with growth, sociodemographic, and lifestyle characteristics. A nationally representative, school-based, cross-sectional study was conducted in Israeli adolescents aged 11–18 years during 2015–2016. A self-administered survey queried sociodemographics, health behaviors, and diet. Weight and height were measured, and WHO height z-scores and BMI cutoffs were calculated. Food frequency questionnaire data were analyzed using principal components analysis (PCA) to identify DPs. Associations between growth, lifestyle, and sociodemographic characteristics and DPs were modeled using multivariable logistic regressions. A total of 3902 adolescents (46% males, mean age 15.2 ± 1.6 years) completed the survey. PCA identified five DPs, accounting for 38.3% of the total variance. The first two prominent DPs were the ‘plant-based food’ DP, which was associated with the female sex, higher socioeconomic status, overweight/obesity, and healthy lifestyle and the ‘junk food’ DP, which was associated with lower SES, unhealthy lifestyle, and lower height z-scores. Our results elucidate major DPs that strongly correlate with lifestyle risk behaviors and suboptimal growth among adolescents. Implementing screening for DPs should be further examined to identify higher risk health factors among youth.
