Randomized Controlled TrialEffectiveness of a 12-month randomized clinical trial to increase physical activity in multiethnic postpartum women: results from Hawaii's Nā Mikimiki Project.
Few postpartum ethnic minority women perform leisure-time moderate-to-vigorous physical activity (MVPA). The study tested the effectiveness of a 12-month tailored intervention to increase MVPA in women with infants 2-12months old. ⋯ A tailored intervention effectively increased MVPA over 12months in multiethnic women with infants, particularly those with more than one child.

Overcoming the challenges of conducting physical activity and built environment research in Latin America: IPEN Latin America.
There is evidence linking the built environment (BE) with physical activity (PA), but few studies have been conducted in Latin America (LA). State-of-the-art methods and protocols have been designed in and applied in high-income countries (HIC). In this paper, we identify key challenges and potential solutions to conducting high-quality PA and BE research in LA. ⋯ Conducting high-quality PA and BE research in LA is challenging but feasible. Networks of institutions and researchers from both HIC and LMIC play a key role. The lessons learned from the IPEN LA study may be applicable to other LMIC.

Comparative StudyHow far from home? The locations of physical activity in an urban U.S. setting.
Little is known about where physical activity (PA) occurs, or whether different demographic groups accumulate PA in different locations. ⋯ A large proportion of MVPA time is spent at "near" locations, corresponding to the home neighborhood studied in previous PA research. "Away" locations also host time spent in MVPA and should be the focus of future research.

Comparative StudyImpact of trained champions of comprehensive school physical activity programs on school physical activity offerings, youth physical activity and sedentary behaviors.
A quasi-experimental cluster-controlled design was used to test the impact of comprehensive school physical activity program (CSPAP) professional development on changes in school physical activity (PA) offerings, moderate-to-vigorous physical activity (MVPA) and sedentary behaviors of 9-14 year-old children during school. ⋯ This study provides preliminary evidence for CSPAP professional development programs to influence school-level PA offerings and offset student-level declines in MVPA and increases in sedentary behavior.

Comparative StudyEffects of breastfeeding on postpartum weight loss among U.S. women.
The aim of this study is to evaluate the effects of breastfeeding on maternal weight loss in the 12months postpartum among U.S. women. ⋯ Our study provides evidence that exclusive breastfeeding for at least three months has a small effect on postpartum weight loss among U.S. women.
