A variety of study designs are used to measure the impact of an intervention on the weight and health of children with obesity. While the gold standard remains the randomized controlled trial, a common approach used in clinical practice because of convenience and ease is the ‘pre-post’ design. This includes following one group of participants and comparing changes over time, usually before and after a structured intervention. Continue reading
What’s more persuasive – definitive results from a double-blind, placebo-controlled RCT to show treatment A is superior to treatment B or one person’s journey in being diagnosed and treated for a chronic illness? In the end, it depends on context. Continue reading
In participatory research, individuals who have the potential to benefit and learn from research are included as partners in the research process. Continue reading
Over the years, we’ve published a few review articles. From narrative to integrative to systematic….what do the different terms mean, you ask? Continue reading
Not long ago, a biostatistics colleague of mine told me an interesting story. Continue reading
We’ve all heard that old saying: “It’s not just what you say, it’s how you say it.” Continue reading
A longstanding challenge in nutrition and obesity research (and weight management) is the accurate and reliable measurement of energy balance – energy in & energy out. Historically, these variables have been assessed using different self-report or proxy-report tools, such as diaries, recalls, and surveys. When used to approximate intake and expenditure, most clinicians and researchers have held the view that, while imperfect, gathering some information was better than nothing. Well, that viewpoint is changing.
A recent paper by leaders in the field provides a compelling argument to stop relying on subjective, self-report tools and start adhering to a higher ideal to measure energy balance using objective methods that provide more confidence in the quality of the data being collected.
This directive may not be easy, convenient, or inexpensive, but it’s fundamentally important to advancing the science in this field and informing guidelines/recommendations for individuals and families.

There’s growing interest in the use of wearable technology to facilitate lifestyle changes. A recent commentary in JAMA highlights the need to link emerging technologies with what we already know regarding concepts and theories in behavior change research to make the biggest impact.
