In our recent dietary assessment field studies on passive dietary monitoring in Ghana, we have collected over 250k in-the-wild images. The dataset is an ongoing effort to facilitate accurate measurement of individual food and nutrient intake in low and middle income countries with passive monitoring camera technologies. The current dataset involves...

Background Preschool-aged children’s physical activity (PA) and screen time (ST) are important health-related behaviours likely influenced by PA opportunities, parental perceptions of neighbourhood safety and parenting practices pertaining to PA and ST. How these factors interact to impact on young children’s PA and ST, and whether their effects ar...

Objective Passive, wearable sensors can be used to obtain objective information in infant feeding, but their use has not been tested. Our objective was to compare assessment of infant feeding (frequency, duration, duration and cues) by self-report and that of the Automatic Ingestion Monitor-2 (AIM-2). Design A cross-sectional pilot study was condu...

Background: While children have been shown to have increased BMI during the summer compared to the school year, it is not known if this may be due to seasonal variations in height or weight separately. Methods: Trained nurses measured heights (cm) and weights (kg) in a cohort of Kindergarteners ( n = 7648) twice per year from the beginning of kinde...

Knowing the amounts of energy and nutrients in an individual’s diet is important for maintaining health and preventing chronic diseases. As electronic and AI technologies advance rapidly, dietary assessment can now be performed using food images obtained from a smartphone or a wearable device. One of the challenges in this approach is to computatio...

Background Caregivers’ influence on young children’s eating behaviors is widely recognized. Nutritional interventions that focus on the promotion of children’s healthy diet should actively involve parents, focusing on their feeding behaviors and practices. Methods This work aims to describe the development and study protocol of the SmartFeeding4Ki...
Article
The optimal approach to feeding preschool children balances expectation setting (demandingness) with responsivity to the child (responsiveness), and ideal feeding practices use environmental structuring and covert, non-directive control strategies while maintaining responsiveness. However, research has not examined the extent to which demandingness...
Article
Parents influence their child's vegetable intake through their feeding style, i.e. the emotional tone established around feeding, and vegetable parenting practices (VPPs), i.e. the specific behaviors employed to influence their child's vegetable intake. A model of precision food parenting proposes that child healthy dietary intake could be optimize...
Article
Full-text available
Precision medicine, nutrition and behavioral interventions are attempting to move beyond the specification of therapies applied to groups, since some people benefit, some do not and some are harmed by the same therapy. Instead, precision therapies are attempting to employ diverse sets of data to individualize or tailor interventions to optimize the...
Article
There is little information on the determinants of healthy sleep habits (HSH) among women of childbearing age (WOCBA). The objective was to identify WOCBA’s beliefs on HSH based on the Reasoned Action Approach. Thirty WOCBA (18–41 years) were randomly assigned to answer questions regarding one of three HSH: avoiding screen use in bed; avoiding caff...

Obesity prevention interventions generally have either not worked or had effects inadequate to mitigate the problem. They have been predicated on the simple energy balance model, which has been severely questioned by biological scientists. Numerous other etiological mechanisms have been proposed, including the intestinal microbiome, which has been...

Camera-based passive dietary intake monitoring is able to continuously capture the eating episodes of a subject, recording rich visual information, such as the type and volume of food being consumed, as well as the eating behaviours of the subject. However, there currently is no method that is able to incorporate these visual clues and provide a co...

Purpose There has been a call to improve measurement rigour and standardization of food parenting practices measures, as well as aligning the measurement of food parenting practices with the parenting literature. Drawing from an expert-informed conceptual framework assessing three key domains of food parenting practices (autonomy promotion, control...
Article
Full-text available
Background Many tools have been developed to measure physical activity parenting practices (PAPP). Currently, there is little standardization on how PAPP constructs are operationalized for 5–12 year-old children. Given this lack of consistency our team have started the process of standardizing the measurement of PAPP by developing an item bank whic...

Being able to draw accurate conclusions from childhood obesity trials is important to make advances in reversing the obesity epidemic. However, obesity research sometimes is not conducted or reported to appropriate scientific standards. To constructively draw attention to this issue, we present 10 errors that are commonly committed, illustrate each...
Article
Background Although physical activity (PA) has been shown in helping prevent and treat obesity, current PA interventions are still not effective in ameliorating the obesity epidemic. Additional forms of PA need to be investigated to improve PA engagement and outcomes. We hypothesize that pairing a narrative (i.e., story) with an active video game (...

Objective Survival rates for paediatric cancers have increased dramatically since the 1970s, but childhood cancer survivors (CCS) are at increased risk for several chronic diseases throughout life. Nutrition interventions promoting healthy family meals may support wellness for survivors, but little research has explored CCS family food preparation...
Article
Careful consideration of the validity and reliability of methods intended to assess dietary intake is central to the robustness of nutrition research. A dietary assessment method with high validity is capable of providing useful measurement for a given purpose and context. More specifically, a method with high validity is well grounded in theory; i...

Despite our best efforts, pediatric obesity remains an important public health issue. Although many different approaches to address this condition have been utilized, few have achieved long-term success. Technology is increasingly being explored as a convenient and accessible method for delivering behavioral interventions. Stephens and colleagues r...
Article
Background: Previous research indicates games for health have substantial promise in promoting change in children's diet and physical activity (PA) behavior for obesity and diabetes prevention, but the research has generally not been rigorous. The study reported here was an efficacy trial of two role-playing videogames played in sequence, "Escape...

Abstract Children gain weight at an accelerated rate during summer, contributing to increases in the prevalence of overweight and obesity in elementary-school children (i.e., approximately 5 to 11 years old in the US). Int J Behav Nutr Phys Act 14:100, 2017 explained these changes with the “Structured Days Hypothesis” suggesting that environmental...

Full-text available
Purpose of Review The simple energy balance model of obesity is inconsistent with the available findings on obesity etiology, prevention, and treatment. Yet, the most commonly stated causes of pediatric obesity are predicated on this model. A more comprehensive biological model is needed upon which to base behavioral interventions aimed at obesity...

Architects strive to design functional and fashionable buildings, but they struggle with subjects beyond their expertise—such as anticipating and influencing how users respond to built environments. This knowledge gap is crucial because the world's most serious design problems are behavioral, not architectural, from climate change to crime to hunge...

Obesity raises blood pressure (BP) in children and adults. Nevertheless, as obesity increased around the globe, population systolic and diastolic blood pressures were flat or fell. Examining children is insightful because pediatric trends are largely unconfounded by antihypertensive therapy. Decomposing BP into arterial types, large artery measures...
