Association of change in the school travel mode with changes in different physical activity intensities and sedentary time: A International Children's Accelerometry Database Study.
Our aim was to assess the association between changes in active travel to school and changes in different intensities of physical activity (i.e. moderate - MPA and vigorous - VPA) and time spent sedentary (SED) among adolescents and assess the moderating effect of children's sex, age and weight status. Data from six cohort studies in the International Children's Accelerometry Database were used (4108 adolescents aged 10-13y at baseline, with 1.9±0.7y of follow-up). Participants self-reported travel mode to school at baseline and follow-up. ⋯ There were no associations with SED. An interaction was observed, age group moderated the association with change in VPA: among 12-13y-olds a greater increase in VPA was observed for the passive/active group compared to active/active. Promoting active travel to school can be a strategy to attenuate the decline in physical activity through adolescence.

Should physical activity calorie equivalent (PACE) labelling be introduced on food labels and menus to reduce excessive calorie consumption? Issues and opportunities.
PACE food labelling seeks to provide kilocalorie information with an interpretation of what the kilocalorie content of the food item or meal means for energy expenditure. For example, "the kilocalories in this pizza require 110 minutes of walking to expend". ⋯ However, several criticisms of this labelling system have been raised. This commentary explores both the issues and opportunities related to PACE food labelling, arguing that the benefits of implementation outweigh potential unintended consequences.

Impact of geographic access to primary care providers on pediatric behavioral health screening.
Behavioral Health (BH) screening is critical for early diagnosis and treatment of pediatric mental disorders. The objective of this study was to assess the impact of geographic access to primary care providers (PCP) on pediatric BH screening in children with different race/ethnicity. A retrospective cohort study was conducted using the 2013-2016 administrative claims data from a large pediatric Medicaid Managed Care Plan that have been linked to 2010 US Census data and the 2017 National Provider Identifier (NPI) Registry. ⋯ Multivariable analysis stratified by individual race/ethnicity revealed that Hispanic and Black children were more vulnerable to the geographic access barriers than their non-Hispanic White counterparts. The increase in travel distance to the nearest PCP was negatively associated with screening uptake only among Hispanics (10-20 miles vs. 0-10 miles: OR = 0.78, 95% CI [0.71-0.86]; 20-30 miles vs. 0-10 miles: OR = 0.35, 95% CI [0.23-0.54]). In a subgroup that had access to at least one PCP within 10 miles of travel distance, the variation in PCP density had a greater impact on the screening uptake among Hispanics and Blacks than that in non-Hispanic Whites.

Risk of hypertension in school-aged children undergoing a long-term community-based lifestyle intervention: Tehran lipid and glucose study.
Childhood hypertension which increases the risk of cardiovascular diseases in adulthood is becoming more prevalent. For the first time in the Middle-East region, this study aimed to assess the long-term effectiveness of a community-based lifestyle intervention on the incidence of hypertension in school-aged children during 16 years of follow-up. This study was conducted within the framework of the Tehran Lipid and Glucose Study (TLGS). ⋯ Although the risk of hypertension in boys was more than twice that observed in girls, the effectiveness of the recent community-based healthy lifestyle intervention was observed only in girls and not in boys. Further studies are needed to understand gender differences in promoting the effectiveness of similar future programs. The TLGS is registered at Iran Registry for Clinical Trials, a WHO primary registry (http://irct.ir; IRCTID: IRCT138705301058N1).

Changes in parental smoking behavior and children's health status in Chile.
Studies on parental smoking behavior have mostly been conducted for developed countries and show that current parental smoking is negatively associated with children's current health. Using four waves of a Chilean longitudinal survey (Encuesta de Protección Social), we estimate probit and ordinary least squares models relating parents' self-report of their children's current health status to several covariates, including current parental smoking status and change (transitions) in parental smoking status across the waves of the survey. The data were collected in the years 2004, 2006, 2009, and 2015. ⋯ Cessation among mothers who are unemployed or inactive is also associated with a more positive assessment of their children's health status. The findings suggest that cessation programs may have health benefits not only for smoking parents, but also for their children. Improving coverage or establishing a national cessation program may have important present and future effects on population health and well-being.
