Mobile technologies offer the potential for efficacious and cost-effective lifestyle interventions for weight loss. Extant research indicates that mobile health (mHealth) lifestyle interventions are potentially effective and practical methods of weight loss, but it is less known what intervention characteristics are associated with weight loss effects. This meta-analysis examined the effectiveness of mHealth physical activity interventions for weight loss compared with non-technology/usual care interventions and the moderating effects of behavioral change theories, techniques, and mobile technologies. A total of 24 studies were identified based on inclusion criteria. Weight loss was the primary outcome. The results showed a medium significant effect size ( d = 0.395; 95% CI  = 0.243, 0.546; Z = 5.107, p < 0.001; N = 5146) favoring mHealth interventions. Interventions were significantly more effective when wearable devices were used ( QB = 4.102, df = 1, p < 0.05) and when feedback was employed ( QB = 4.566, df = 1, p < 0.05). The implications for future mHealth intervention design are discussed.

Despite the impact that influential American political bloggers have had on public policies and the mainstream media agenda in recent years, very little research is currently available on the most widely read political bloggers.Through a survey of 66 top American political bloggers, the present study examines this elite group by analyzing their initial and current motivations for blogging as well as their online and offline behaviors. The findings demonstrate that nearly all motivations for blogging have increased over time, with the most substantial increases occurring in extrinsic motivations. The results also reveal a significant association between extrinsic motivations and blogger online and offline political participation. This study demonstrates that future research on political blogs needs to look beyond blog readers and blog content and investigate the influential political bloggers themselves.
