Randomized Controlled Trial
Effectiveness of a multimodal online well-being intervention: a randomized controlled trial.
Well-being encompasses physical, psychological, and social aspects of health and predicts healthcare utilization and expenditures. Despite their potential clinical impact, interventions that leverage social network effects to target well-being are uncommon. ⋯ A multimodal online intervention leveraging social network effects significantly improved well-being over control. Higher levels of participation as well as increasing levels of social integration were associated with greater improvement in well-being.

Randomized Controlled Trial
Daily self-weighing and adverse psychological outcomes: a randomized controlled trial.
Despite evidence that daily self-weighing is an effective strategy for weight control, concerns remain regarding the potential for negative psychological consequences. ⋯ Results indicate that a weight-loss intervention that focuses on daily self-weighing does not cause adverse psychological outcomes. This suggests that daily self-weighing is an effective and safe weight-control strategy among overweight adults attempting to lose weight.

Randomized Controlled Trial Comparative Study
Workplace sitting and height-adjustable workstations: a randomized controlled trial.
Desk-based office employees sit for most of their working day. To address excessive sitting as a newly identified health risk, best practice frameworks suggest a multi-component approach. However, these approaches are resource intensive and knowledge about their impact is limited. ⋯ Australian New Zealand Clinical Trials Registry 00363297.

Review
Childhood obesity policy research and practice: evidence for policy and environmental strategies.
Investigators developed a review system to evaluate the growing literature on policy and environmental strategies to prevent childhood obesity. More than 2000 documents published between January 2000 and May 2009 in the scientific and grey literature were identified (2008-2009) and systematically analyzed (2009-2012). These focused on policy or environmental strategies to reduce obesity/overweight, increase physical activity, and/or improve nutrition/diet among youth (aged 3-18 years). ⋯ Among the evaluation study groupings, only 49% reported sufficient data for population impact ratings, and only 22% qualified for a rating of high population impact. Effectiveness and impact ratings were summarized in graphic evidence maps, displaying effects/associations with behavioral and obesity/overweight outcomes. This paper describes the results and products of the review, with recommendations for policy research and practice.

Tornadoes, with warnings usually issued just minutes before their touchdowns, pose great threats to properties and people's physical and mental health. Few studies have empirically investigated the association of family emergency preparedness planning and observed protective behaviors in the context of tornadoes. ⋯ This study provided empirical evidence on the importance of having a family emergency preparedness plan in mitigating the risk of tornadoes. The findings could be applied to other rapid-onset disasters.
