“…No significant difference was identified in terms of demographic, socioeconomic and anthropometric characteristics between the participants with accelerometer data for reduction (n=176) and those who remained in the sample (n=65) when the most rigorous criteria to define a valid monitoring time was used (5+ days with at least 10 hours/day). These results are in accord with findings that were reported in a validation study of accelerometer measurements to assess physical activity in toddlers 18 . However, these results are in contrast with Mattocks et al 19 , who performed a large field-based study of children and found that the participants who provided valid measures of activity were slightly different from those who did not.…”

Influence of number of days and valid hours using accelerometry on the estimates of physical activity level in preschool children from Recife, Pernambuco, Brazil Abstract -A few studies have proposed the number of hours/day and the number of days of monitoring that should be completed to obtain good quality accelerometry data for preschool children. The aim of this study was to analyze how the estimates of physical activity levels and sample profiles (demographic and anthropometric data) vary according the use of different criteria to define valid monitoring periods. Children (n=180) aged three to five years were randomly selected among participants from a longitudinal study performed in Recife, Brazil. Children wore a GT1M Actigraph accelerometer on the right waist during a period of seven days, including the weekend days, using 15 s epochs. A total of 176 children were included in the study (52.8% boys; mean age of 4.3 years [s=0.8]). Using the criterion of 10+ hours/day of wearing time to define a valid monitoring day, 67.0% (n=118) and 36.9% (n=65) of the children showed 3+ and 5+ valid days, respectively. When the criterion of 5+ hours/day was used, the time spent in moderate activity was approximately 10 minutes shorter than when the criterion of 10+ hours/day was used. The criterion of 10+ hours/day for defining a valid monitoring day leads to a sample size reduction and the criterion of 5+ hours/day underestimates the moderate activity level.

O objetivo deste estudo foi analisar a influencia em se usar diferentes critérios para definir períodos de monitoramento válido na estimativa nos níveis de atividade física e no perfil da amostra.

Childhood obesity is a global health issue. To identify research trends and gaps of childhood obesity research, we reviewed MEDLINE publications from January 2011 to May 2012 and qualitatively analyzed the major domains and themes of research focus. Major domains are: measurements, obesity correlates, prevention interventions, treatment interventions, and policy issues. Key advances and innovations are highlighted within each domain. Emerging areas include the advancement of measurement methodologies that simultaneously capture individual and contextual information across time, analysis of policy problems, and the development of multilevel, community interventions. However, few effective and sustainable interventions are exemplified; some strategies are promising. Recommendations for future research includes the adoption of a systems approach that integrates individual, environmental, and policy change, the scale up and diffusion of innovations, studies of intended and unintended policy impacts, and the design and testing of effective social marketing strategies.

“…17 Children wore the accelerometer over the right hip for 8 days, removing only for sleeping and bathing. Those with $4 days of valid data were included in analyses (n = 286) as 4 days of data ($7.4 hours per day) in this sample provided an acceptable reliability estimate (intraclass correlation coefficient [ICC] .0.70) for light-to vigorousintensity physical activity.…”

WHAT'S KNOWN ON THIS SUBJECT: While obesity-promoting eating, sedentary and physical activity behaviors, and increased prevalence of adiposity are evident from early life, few highquality studies have evaluated interventions that seek to influence the development of these behaviors in very early childhood. WHAT THIS STUDY ADDS:This study highlights the receptivity of first-time parents to interventions focused on their new infant' s eating and active play and provides evidence of effectiveness on some obesity-promoting behaviors in very early childhood. abstract OBJECTIVE: To assess the effectiveness of a parent-focused intervention on infants' obesity-risk behaviors and BMI.METHODS: This cluster randomized controlled trial recruited 542 parents and their infants (mean age 3.8 months at baseline) from 62 first-time parent groups. Parents were offered six 2-hour dietitiandelivered sessions over 15 months focusing on parental knowledge, skills, and social support around infant feeding, diet, physical activity, and television viewing. Control group parents received 6 newsletters on nonobesity-focused themes; all parents received usual care from child health nurses. The primary outcomes of interest were child diet (3 3 24-hour diet recalls), child physical activity (accelerometry), and child TV viewing (parent report). Secondary outcomes included BMI z-scores (measured). Data were collected when children were 4, 9, and 20 months of age. RESULTS:Unadjusted analyses showed that, compared with controls, intervention group children consumed fewer grams of noncore drinks (mean difference = -4.45; 95% confidence interval [CI]: -7.92 to -0.99; P = .01) and were less likely to consume any noncore drinks (odds ratio = 0.48; 95% CI: 0.24 to 0.95; P = .034) midintervention (mean age 9 months). At intervention conclusion (mean age 19.8 months), intervention group children consumed fewer grams of sweet snacks (mean difference = -3.69; 95% CI: -6.41 to -0.96; P = .008) and viewed fewer daily minutes of television (mean difference = -15.97: 95% CI: -25.97 to -5.96; P = .002). There was little statistical evidence of differences in fruit, vegetable, savory snack, or water consumption or in BMI z-scores or physical activity.
