Background: The Nova classification system categorizes foods into 4 processing levels, including ultraprocessed foods (UPFs). Consumption of UPFs is extensive in the United States, and high UPF consumption is associated with chronic disease risk. A reliable and valid method to Nova-categorize foods would advance understanding of UPF consumption and its relationship to health outcomes.

Efficacious treatments for children with obesity have not been broadly disseminated. The Stanford Pediatric Weight Control Program (SPWCP) is grounded in behavioral theory and prior observations, follows a proven treatment model, and is consistent with the US Preventive Services Task Force (USPSTF) recommendations. It has shown high levels of participation and retention and reductions in BMI and percent of median BMI for age and sex comparable to many studied programs, as well as improvements in physiological risk factors, psychological measures, and diet, activity, and screen time behaviors in children with obesity when delivered as a real-world clinical program with sociodemographically diverse families in multiple clinic and community settings.

Background: The recruitment of participants into community-based randomized controlled trials studying childhood obesity is often challenging, especially from low-income racial/ethnical minorities and when long-term participant commitments are required. This paper describes strategies used to recruit and enroll predominately low-income racial/ethnic minority parents and children into the Childhood Obesity Prevention and Treatment Research (COPTR) consortium.

Methods: The COPTR consortium has run four independent 3-year, multi-level (individual, family, school, clinic, and community) community-based randomized controlled trials.

Deconstructing interventions into the specific techniques that are used to change behavior represents a new frontier in behavioral intervention research. This paper considers opportunities and challenges in employing the Behavior Change Techniques Taxonomy (BCTTv1) developed by Michie and colleagues, to code the behavior change techniques (BCTs) across multiple interventions addressing obesity and capture dose received at the technique level. Numerous advantages were recognized for using a shared framework for intervention description.

Evidence from laboratory and field studies indicates that large portions lead to greater food and energy intake relative to small portions. However, most children and adults demonstrate limited abilities to estimate and control the amounts of food they serve and consume. Five potential environmental strategies appear promising for improving portion control in children: (1) using tall, thin, and small volume glasses and mugs, (2) using smaller diameter and volume plates, bowls and serving utensils, (3) using plates with rims, (4) reducing total television and other screen watching and (5) reducing or eliminating eating while watching television and/or other screens.

Western medicine is intrinsically tied with modern Western culture, and as such is foreign to many African cultures. Relying on personal observations from working in Angola as a physiotherapist as well as secondary research, the author explores the divide between Angolan culture and medical practices which are deeply rooted in scientific research. Most strikingly, the author finds that concepts of evidence-based medicine as well as individual human or patients' rights contain aspects foreign to Angolan culture.
