Association between children's caregivers time preferences and childhood overweight and obesity in Mexico.

Background: Parents or children's primary caregivers are a key influence on child weight as both decision makers and role models for eating patterns, physical activity, and other social behaviors. It is unknown whether caregivers' time preferences are associated with overweight or obesity in children. The primary objective was to estimate the association between parents' or caregivers' time preferences and children having overweight or obesity in Mexico.

A review of implementation and evaluation of Pan American Health Organization's policies to prevent childhood obesity in Latin America.

Rationale: To inform future policies, the study objectives were to determine to what extent the policies included in the 5-year Plan of Action for the Prevention of Obesity in Children and Adolescents-proposed by Pan American Health Organization (PAHO) and signed by 19 Latin America countries in 2014-have been implemented and evaluated.

Methods: A scoping review of the Governmental websites for Latin American countries and a literature review was conducted to identify whether policies have been implemented and evaluated. Key information was abstracted.

Effect of a Mobile Phone Intervention on Quitting Smoking in a Young Adult Population of Smokers: Randomized Controlled Trial.

Background: Digital mobile technology presents a promising medium for reaching young adults with smoking cessation interventions because they are the heaviest users of this technology.

Objective: The aim of this study was to determine the efficacy of an evidence-informed smartphone app for smoking cessation, Crush the Crave (CTC), on reducing smoking prevalence among young adult smokers in comparison with an evidence-informed self-help guide, On the Road to Quitting (OnRQ).

Methods: A parallel, double-blind, randomized controlled trial with 2 arms was conducted in Canada to evaluate CTC.
