“…For a planned subanalysis, before- and after-school MVPA served as the outcome variable in an adjusted model. Differences between intervention and control groups at Time 1 were not tested as per expert recomendations 59 (e.g., the 2010 CONSORT statement). 60 Analyses were intention to treat, except where noted.…”

Introduction Increasing children’s cycling to school and physical activity are national health goals. The objective was to conduct an RCT of a bicycle train program to assess impact on students’ school travel mode and moderate to vigorous physical activity (MVPA). Study design Pilot cluster RCT with randomization at the school level and N=54 participants. Setting/participants Fourth–fifth graders from four public schools serving low-income families in Seattle, WA in 2014 with analyses in 2015–2016. All participants were provided and fitted with bicycles, safety equipment (helmets, locks, and lights), and a 2 to 3–hour bicycle safety course. Intervention The intervention was a bicycle train offered daily (i.e., students volunteered to cycle with study staff to and from school). Main outcome measures Time 1 assessments occurred prior to randomization. Time 2 assessments occurred after 3–5 weeks of the intervention (i.e., during Weeks 4–6 of the intervention period). The primary outcome was the percentage of daily commutes to school by cycling measured by validated survey. MVPA, measured by accelerometry and GPS units and processed by machine learning algorithms, was a secondary outcome. Results For two separate adjusted repeated measures linear mixed effects models in which students (N=54) were nested within schools (N=4), intervention participants had: (1) an absolute increase in mean percentage of daily commutes by cycling of 44.9%, (95% CI=26.8, 63.0) and (2) an increase in mean MVPA of 21.6 minutes/day, (95% CI=8.7, 34.6) from Time 1 to Time 2 compared with controls. Conclusions A pilot bicycle train intervention increased cycling to school and daily MVPA in the short term among diverse, inner-city elementary school students. The bicycle train intervention appears promising and warrants further experimental trials among large, diverse samples with longer follow-up.

“…Non-wear time was defined as at least 60 minutes of 0 activity counts (Troiano et al, 2008). To be considered valid for the analysis, at least 10 hours of wear time must have been available for 3 or more of 7 days, which is similar to the wear time requirements of the National Health and Nutrition Examination Study (Evenson, Wen, Metzger, & Herring, 2015). Wear time was validated utilizing ActiLife 6 v5.5 and algorithm developed by Troiano and colleagues (ActiGraph, LLC, 2012; Troiano et al, 2008).…”

Cognitive impairment in older Latinos is a concerning issue due to the rapid growth of this population and their increased risk for dementia due to chronic disease. Evidence, primarily from studies of non-Latino Whites, suggests that physical activity (PA) may reduce cognitive decline. Few longitudinal studies have included older Latinos, objective measures of PA, or neurocognitive tests that assess domains of cognition. The purpose of this longitudinal study was to explore the relation between changes in PA and cognitive decline in older Latinos over an average of five years. Inclusion criteria for the baseline sample were age ≥50 years, Latino ethnicity (English- or Spanish-speaking), no ambulation disability, no evidence of dementia, and Chicago address. Of the 174 baseline participants, 59 (33.9%) participated at follow-up. PA was measured by questionnaire and accelerometer worn for seven days. A battery of neurocognitive tests assessed episodic memory, perceptual speed, and semantic memory. Change in cognitive function was dichotomized to represent maintenance versus decline. Binary logistic regression results indicated that those who had less decline from baseline to follow-up in self-reported light PA maintained episodic memory, OR = 1.16 (95% CI 1.03 – 1.32), while those who had less decline in accelerometer moderate-vigorous bouts maintained semantic memory, OR = 16.08 (95% CI 1.53 – 168.89), controlling for baseline age, chronic health problems, depressive symptoms, and acculturation. These findings suggest that maintenance of PA with aging may prevent cognitive decline. This work can inform future intervention development that aims to maintain PA in order to prevent cognitive decline.

Background Family meal frequency has been consistently and significantly associated with positive youth dietary and psychosocial outcomes but less consistently associated with weight outcomes. Family meal frequency measurement has varied widely and it is unclear how this variation may impact relationships with youth weight, dietary, and psychosocial outcomes. Objective This study assesses how five parent/caregiver-reported and four child-reported family dinner frequency measures correlate with each other and are associated with health-related outcomes. Design/Participants This secondary, cross-sectional analysis uses baseline, parent/caregiver (n=160) and 8–12 year old child (n=160) data from the Healthy Home Offerings via the Mealtime Environment (HOME) Plus trial (collected 2011–2012). Data were obtained from objective measurements, dietary recall interviews, and psychosocial surveys. Outcome measures Outcomes included child body mass index z-scores (BMIz), fruit, vegetable and sugar-sweetened beverage intake, dietary quality (Healthy Eating Index-2010 [HEI-2010]), family connectedness, and meal conversations. Statistical analyses performed Pearson correlations and general linear models were used to assess associations between family dinner frequency measures and outcomes. Results All family dinner frequency measures had comparable means and were correlated within and across parent/caregiver- and child-reporters (r=0.17–0.94, p<0.01). In unadjusted analyses, 78% of family dinner frequency measures were significantly associated with BMIz scores and 100% were significantly associated with fruit/vegetable intake and HEI-2010. In adjusted models, most significant associations with dietary and psychosocial outcomes remained but associations with child BMIz remained significant only for parent/caregiver- (β±SE= −0.07±0.03; p<0.05) and child-reported (β±SE= −0.06+0.02; p<0.01) family dinner frequency measures asking about ‘sitting and eating’ dinner. Conclusions In spite of phrasing variations in family dinner frequency measures (e.g., which family members were present and how meals were occurring), few differences were found in associations with dietary and psychosocial outcomes but differences were apparent for child BMIz, which suggests phrasing of family dinner frequency measures may influence associations found with weight outcomes.
