Caloric compensation in preschool children: relationships with body mass and differences by food category

Maintaining a healthy weight may involve compensating for previously consumed calories at subsequent meals. To test whether heavier children demonstrated poorer caloric compensation across a range of conditions, and to explore whether compensation failure was the result of inadequate adjustment of overall intake or specific over-consumption of highly palatable, high energy-density 'junk' foods, we administered two compensation tests to a sample of 4-5 y olds. For Test A, preloads varied only in carbohydrate content and were organoleptically indistinguishable (200 ml orange-flavored beverage [0 kcal vs. 200 kcal]). For Test B, the preloads varied substantially in both macronutrient composition and learned gustatory cues to caloric content (200 ml water [0 kcal] vs. 200 ml strawberry milkshake [200 kcal]). Each preload was followed 30 min later by a multi-item ad-libitum meal containing junk foods (chocolate cookies, cheese-flavored crackers) and core foods (fruits and vegetables, bread rolls, protein foods). Testing took place at the children's own school under normal lunch-time conditions. Children were weighed and measured. Caloric compensation occurred in both tests, in terms of total, junk and core food intake (RMANOVA, all p < 0.01). Higher BMI z scores were associated with greater average caloric compensation (r = -0.26p < 0.05), such that overweight/obese children showed least compensation (41%), children over the 50th centile the next least (59%), and children under the 50th centile (80%) the most. For Test A only, obese/overweight children compensated less well than normal weight children in terms of junk food intake (RMANOVA preload-by-weight group interaction p < 0.05), with no significant effect for core foods. Our results suggest that caloric compensation is consistently poorer in heavier children, and that overweight/obese children's preferences for junk foods may overwhelm intake regulation mechanisms within meals containing those foods.

Is comfort food actually comforting for emotional eaters? A (moderated) mediation analysis

Item does not contain fulltextAn important but unreplicated earlier finding on comfort eating was that the association between food intake and immediate mood improvement appeared to be mediated by the palatability of the food, and that this effect was more pronounced for high than for low emotional eaters [26]. This has not yet been formally tested using mediation and moderated mediation analysis. We conducted these analyses using data from two experiments on non-obese female students (n = 29 and n = 74). Mood and eating satisfaction in Study 1, and mood, tastiness and emotional eating in Study 2 were all self-reported. In Study 1, using a sad mood induction procedure, emotional eaters ate more food, and when mood was assessed immediately after food intake, 'eating satisfaction' acted as mediator between food intake and mood improvement (decrease in sadness or increase in happiness). In Study 2, where we measured the difference in actual food intake after a control or a stress task (modified Trier Social Stress Test), and assessed mood during the food intake after stress, we found significant moderated mediation. As expected, there was a significant positive mediation effect of tastiness between food intake and mood improvement in the high emotional eaters, but also a significant negative mediation effect of tastiness between food intake and mood improvement in the low emotional eaters. This suggests that tastiness promotes 'comfort' from food in female emotional eaters, but conflicts in non-emotional eaters with a tendency to eat less when stressed. In conclusion, palatable food may indeed provide comfort specifically for high emotional eaters during eating.10 p

Binge eating behaviours and food cravings in women with Polycystic Ovary Syndrome

Polycystic Ovary Syndrome (PCOS), the most common endocrine condition in women, is often anecdotally associated with binge eating behaviours and food cravings; however there is a paucity of research. This study aimed to report the prevalence of binge eating and food cravings and their relation to obesity risk in women with PCOS. Participants completed an online survey including the Bulimia Investigatory Test, Edinburgh, Food Cravings-Trait Questionnaire and the Three Factor Eating Questionnaire revised-18. The study included obese (n = 340), overweight (n = 70) and lean (n = 45) women with PCOS and lean healthy women (n = 40). Sixty percent of obese women with PCOS were categorised with binge-eating behaviour, with 39% presenting with clinically significant behaviour. Obese women with PCOS presented with high mean food cravings-trait scores (131.6 ± 28.9) that were significantly greater compared with lean (114.0 ± 34.9) and overweight women with PCOS (120.1 ± 29.5; p < 0.001). Multiple regression exploring relations between eating styles and adiposity explained 59% of the variance in binge eating symptom scores in women with PCOS (F = 173.8; p < 0.001, n = 463): significant predictors were food cravings total score (beta = 0.52; p < 0.001), emotional eating score (beta = 0.16; p < 0.001), BMI (beta = 0.13; p < 0.001) and uncontrolled eating score (beta = 0.10; p < 0.01). Compared with lean healthy women, lean women with PCOS exhibited significantly higher binge eating symptom scores (10.9 ± 7.8 versus 7.4 ± 6.0; p < 0.05), though similar total food craving scores (114.0 ± 34.9 versus 105.6 ± 26.6: NS). This study is the largest, to date, to robustly report that a high proportion of women with PCOS exhibit binge eating behaviours. We recommend screening women with PCOS for binge eating behaviours to help inform the choice of weight management approach for this clinical population

Influences of Parental Snacking-Related Attitudes, Behaviours and Nutritional Knowledge on Young Children's Healthy and Unhealthy Snacking:The ToyBox Study

This study investigated parental influences on preschool children’s healthy and unhealthy snacking in relation to child obesity in a large cross-sectional multinational sample. Parents and 3– 5 year-old child dyads (n = 5185) in a kindergarten-based study provided extensive sociodemographic, dietary practice and food intake data. Parental feeding practices that were derived from questionnaires were examined for associations with child healthy and unhealthy snacking in adjusted multilevel models, including child estimated energy expenditure, parental education, and nutritional knowledge. Parental healthy and unhealthy snacking was respectively associated with their children’s snacking (both p < 0.0001). Making healthy snacks available to their children was specifically associated with greater child healthy snack intake (p < 0.0001). Conversely, practices that were related to unhealthy snacking, i.e., being permissive about unhealthy snacking and acceding to child demands for unhealthy snacks, were associated with greater consumption of unhealthy snacks by children, but also less intake of healthy snacks (all p < 0.0001). Parents having more education and greater nutritional knowledge of snack food recommendations had children who ate more healthy snacks (all p < 0.0001) and fewer unhealthy snacks (p = 0.002, p < 0.0001, respectively). In the adjusted models, child obesity was not related to healthy or unhealthy snack intake in these young children. The findings support interventions that address parental practices and distinguish between healthy and unhealthy snacking to influence young children’s dietary patterns

Teachers’ and Parents’ Perspectives on the Feasibility of a Preschool-Based Behavioral Intervention to Prevent Obesity: An Embedded Qualitative Study within ToyBox Study Malaysia

The aim of this qualitative study, an embedded component of ToyBox Study Malaysia (TSM), was to elicit the perspectives of teachers and parents regarding the implementation of TSM. TSM is a preschool-based behavioral intervention program aimed at improving healthy energy balance-related behaviors among young children attending preschools. The qualitative study adopted a descriptive-interpretive methodology, and triangulated data collected through semi-structured focus groups with artifacts collected. The setting involved rural and metropolitan preschools in Sarawak and Peninsular Malaysia, respectively. In Sarawak, 11 teachers and 20 parents from six intervention preschools participated in this study. In Peninsular Malaysia, 14 preschool teachers and seven assistant teachers representing all 15 intervention preschools participated in the study. Data were analyzed thematically and four overarching themes were identifed: impact of TSM on the children’s knowledge and practices of healthy energy balance-related behaviors; spheres of infuence upon the children’s energy balance-related behaviors; constraints and afordances related to the implementation of TSM; and prospective sustainability of TSM. The triangulation of data from teachers, parents, and the artifacts related to TSM enabled the corroboration of evidence to support the themes identifed. This study provides evidence on the reciprocal interactions between the teachers and parents who played key roles in facilitating behavioral change in the children, and the children who, in turn, served as change agents beyond the preschool. Furthermore, the mediational tools such as the TSM crockery and availability of healthy food and water led to the reported behavioral changes at both rural and metropolitan settings

From ToyBox Study to eToyBox : Advancing Childhood Obesity Reduction in Malaysian Kindergartens

Prevention and treatment of childhood obesity is a global concern, and in Malaysia, it is considered a national public health priority. Determinants of childhood obesity are multifactorial and include factors that directly and indirectly influence energy balance-related behaviours, including energy intake and energy expenditure. Interventions to address childhood obesity that have multiple components at different levels have been shown to be the most influential. The ToyBox-study is a childhood obesity intervention aimed at preschool-aged children and their families that had been shown to be effective in several European countries and so was chosen for adaption for the Malaysian setting. Materials were translated and adjusted for the Malaysian context and audience and implemented in kindergartens in Peninsular Malaysia and Sarawak. However, during the COVID-19 pandemic and lockdown, teaching transitioned to being online. This brought an opportunity to reach a wider audience and consider the long-term sustainability of the intervention, and thus eToybox was born. eToybox aims to bring support for healthy energy balance behaviours directly to the teachers, into kindergartens and homes, to encourage families to be active and eat healthily, and prevent or reduce obesity. Through online innovation, the Toybox Study Malaysia programme has been expanded to enhance its potential to impact the promotion of healthy lifestyles among preschoolers and their families, highlighting the importance of a holistic approach to preventing and treating childhood obesity in Malaysia
