Eating behaviors, which are shaped during childhood, are one of the important factors influencing children\'s growth. This study aimed to investigate the variations in eating behaviors among Vietnamese preschool children aged 3 to 6 years using the Children Eating Behavior Questionnaire (CEBQ) and their association with anthropometric Z-scores. A cross-sectional study was conducted on 10 172 children from 36 to 72 months old, recruited from three different socioeconomic regions of Hanoi. Differentiation of eating behaviors between two sexes was observed across all age groups, but most obvious at 36 to 48 months of age. The subscales of emotional overeating (EOE), enjoyment of food (EF), and desire to drink (DD) were higher in 60- to 72-month age groups and vice versa for slowness in eating (SE) and emotional undereating (EUE) subscales. Analyses using the general linear model showed that CEBQ subscales were associated with anthropometric Z-scores in both girls and boys.

OBJECTIVE: Anorexia nervosa (AN) is characterized by a tendency to limit intake of food, with specific restriction of foods that are generally considered highly palatable. This observation raises questions about whether reward processing is disturbed in AN. This study examined whether adolescents with AN differ from healthy control peers (HC) in anticipatory and consummatory reward processing.
METHODS: Adolescents with AN (n = 71) and HC (n = 41) completed the Temporal Experience of Pleasure Scale (TEPS). The TEPS Anticipatory Pleasure scale was divided into two further subscales (Food and Non-food). Anticipatory (Food and Non-food) and Consummatory Pleasure (Non-food) scores were compared between adolescents with AN and HC using independent t-tests.
RESULTS: TEPS scores were significantly lower among adolescents with AN than HC in Anticipatory Pleasure Food (t(110) = 7.80, p < 0.001) and Non-food (t(110) = 4.36, p < 0.001), and Consummatory Pleasure (t(110) = 2.60, p = 0.01) subscales. When controlling for BDI score, there was no significant group difference in TEPS Consummatory Pleasure scores (t(108) = 0.88, p = 0.38). Among adolescents with AN, Food Anticipatory Pleasure was significantly negatively correlated with all EDE-Q subscales and global score (r(68) = -0.38, p = 0.002) and positively correlated with food intake at a laboratory buffet meal (r(61) = 0.53, p < 0.001).
CONCLUSIONS: Measures of both anticipatory and consummatory reward were reduced among adolescents with AN with a short duration of illness. In this study, eating disorder symptoms were related to diminished reward responses in anticipation of food. Dampened anticipatory reward response may comprise a mechanism of illness in AN that should be subject to further study.

Sweet and salty tastes are highly palatable and drive food consumption and potentially uncontrolled eating, but it remains unresolved whether the ability to recognize sweet and salty affects food reward and uncontrolled eating. We investigate the association of sweet and salty taste recognition with liking and wanting and uncontrolled eating. Thirty-eight, mainly female (68%) participants of the Obese Taste Bud study, between 22 and 67 years old, with a median BMI of 25.74 kg/m2 (interquartile range: 9.78 kg/m2) completed a taste test, the Leeds Food Preference Questionnaire to assess food reward, the Power of Food Scale (PFS) and the Three-Factor Eating Questionnaire to assess different aspects of uncontrolled eating. Better salty taste recognition predicted greater implicit wanting for high-fat savory foods (β = 0.428, p = 0.008) and higher PFS total (β = 0.315; p = 0.004) and PFS present subscale scores (β = 0.494, p = 0.002). While neither sweet nor salty taste recognition differed between lean individuals and individuals with obesity, those with greater trait uncontrolled eating showed significantly better salty taste recognition (U = 249.0; p = 0.009). Sweet taste recognition did not associate with food reward or uncontrolled eating. Better salty but not sweet taste recognition associates with a greater motivation for, but not liking of, particularly savory high-fat foods and further relates to greater loss of control over eating. Salty taste perception, with taste recognition in particular, may comprise a target to modulate food reward and uncontrolled eating.

BACKGROUND: Evidence assessing the relationship between chronotype and disordered eating in adolescents is scarce. The current study tried to evaluate the association between chronotype and disordered eating in a sample of Spanish adolescents.
METHODS: This secondary cross-sectional study analyzed data from the Eating Healthy and Daily Life Activities (EHDLA) study. The sample consisted of 703 adolescents (56.3% girls) aged between 12 and 17 years from the Valle de Ricote (Region of Murcia, Spain). Chronotype was assessed using the Morningness/Eveningness Scale in Children (MESC). Disordered eating was evaluated by two psychologists using the Sick, Control, One, Fat, and Food (SCOFF) questionnaire.
RESULTS: Adolescents with an eveningness chronotype showed a higher SCOFF score (estimated marginal mean [M] = 1.1; 95% confidence interval [CI] 0.7 to 1.5) in comparison with adolescents with a morningness chronotype (M = 0.7; 95% CI 0.5 to 0.8) (p = 0.010), as well as with those with an intermediate chronotype (M = 0.6; 95% CI 0.5 to 0.8) (p = 0.032). A higher predictive probability of having disordered eating was identified in adolescents with an eveningness chronotype (39.5%; 95% CI 22.8% to 59.1%), compared to adolescents with an intermediate chronotype (14.9%; 95% CI 10.8% to 20.1%) (p = 0.008) and with their counterparts with a morningness chronotype (16.9%; 95% CI 11.6% to 24.0%) (p = 0.021).
CONCLUSIONS: This study reveals that adolescents with an eveningness chronotype are more likely to exhibit disordered eating behaviors compared to those with morningness or intermediate chronotypes. These findings highlight the importance of considering chronotype in adolescent health, particularly in developing targeted interventions to prevent eating disorders.

OBJECTIVE: This study aimed to investigate the association of body mass index (BMI) with the weekly frequency of moderate-intensity physical activity, eating behavior, and the use of the Internet or games among Korean middle school students.
METHODS: The data of 23,583 Korean middle school students were collected from the 2023 Korean Student Health Examination. The collected data were analyzed using frequency, chi-square, and multivariate logistic regression analyses.
RESULTS: The results also showed that the higher the BMI, the greater the likelihood of moderate-intensity physical activity. The likelihood of breakfast intake reduced as the BMI increased. However, the likelihood of using the Internet or games increased with an increase in BMI. The results revealed that 28% (6594 of 23,583) of middle school students rarely participate in moderate-intensity physical activity, while 32% (7553 of 23,583) participate only once or twice a week. The results also showed that the higher the BMI, the higher the likelihood of moderate-intensity physical activity. Among those who were underweight, the odds ratio (OR) of 3-4 days of participation in moderate-intensity physical activity was 0.764 (95% confidence interval [CI]: 0.664-0.880; p < 0.001). Among those who were healthy, the OR of more than 5 days of participation was 1.279 (95% CI: 1.131-1.446; p < 0.001). Among those who were overweight, the OR of 3-4 days and more than 5 days of participation was 1.172 (95% CI: 1.019-1.348; p = 0.026) and 1.181 (95% CI: 1.011-1.380; p = 0.036), respectively. The likelihood of the use of the Internet or games increased with an increase in BMI. The OR of the use of the Internet or games was 0.876 (95% CI: 0.806-0.952; p = 0.002) and 0.824 (95% CI: 0.743-0.913; p < 0.001) among those who were healthy and those who were overweight, respectively. However, the likelihood of breakfast intake reduced as the BMI increased. Among those who were underweight, the OR of always eating breakfast and mostly eating breakfast was 1.299 (95% CI: 1.114-1.515; p < 0.001) and 1.236 (95% CI: 1.045-1.461; p = 0.013), respectively. Among those who were healthy, the OR of always eating breakfast was 1.157 (95% CI: 1.026-1.305; p = 0.018). Among those who were overweight, the OR of mostly eating breakfast was 1.215 (95% CI: 1.030-1.433; p = 0.021).
CONCLUSIONS: Given this, outdoor sports may increase adolescents\' participation in physical activities by helping them break away from repetitive ball games and increasing their overall interest and participation in physical activities. Overall, our results suggest the need to move away from traditional physical education and develop engaging physical activity programs that motivate students to participate in moderate-intensity physical activities.

Food addiction (FA) is associated with greater severity on many eating-related correlates when comorbid with binge eating disorder (BED) but no study has established this relation across the whole spectrum of binge eating, i.e., from no BED to subthreshold BED to BED diagnosis. This study aims to examine the effect of the presence of FA on the severity of eating behaviors and psychological correlates in patients without BED, subthreshold BED or BED diagnosis. Participants (n = 223) were recruited at a university center specialized in obesity and eating disorder treatment and completed a semi-structured diagnostic interview and questionnaires measuring eating behaviors, emotional regulation, impulsivity, childhood interpersonal trauma, and personality traits. They were categorized by the presence of an eating disorder (no BED, subthreshold BED, or BED) and the presence of FA. Group comparisons showed that, in patients with BED, those with FA demonstrated higher disinhibition (t(79) = -2.19, p = 0.032) and more maladaptive emotional regulation strategies (t(43) = -2.37, p = 0.022) than participants without FA. In patients with subthreshold BED, those with FA demonstrated higher susceptibility to hunger (t(68) = -2.55, p = 0.013) and less cooperativeness (t(68) = 2.60, p = 0.012). In patients without BED, those with FA demonstrated higher disinhibition (t(70) = -3.15, p = 0.002), more maladaptive emotional regulation strategies (t(53) = -2.54, p = 0.014), more interpersonal trauma (t(69) = -2.41, p = 0.019), and less self-directedness (t(70) = 2.14, p = 0.036). We argue that the assessment of FA provides relevant information to complement eating disorder diagnoses. FA identifies a subgroup of patients showing higher severity on many eating-related correlates along the binge eating spectrum. It also allows targeting of patients without a formal eating disorder diagnosis who would still benefit from professional help.

OBJECTIVE: This study aims to explore obesity-related behaviors (ORB) and health-related quality of life (HRQoL) in socioeconomically vulnerable children, while also examining potential associations between these variables.
METHODS: A total of 721 children enrolled in after-school care programs for socioeconomically vulnerable children participated in this study. Height (in cm) and weight (in kg) were measured directly by trained research assistants. ORB, including eating behaviors and physical activity, was assessed utilizing the Nutrition Quotient Questionnaire. HRQoL was measured utilizing the PedsQL™ 4.0. Data were analyzed using logistic regression.
RESULTS: The findings revealed that participants exhibited lower levels of ORB and reduced HRQoL, particularly in the physical health dimension of HRQoL. Inadequate physical activity and poor dietary habits were strongly associated with a 2.625-fold (OR = 2.625, 95% CI = 1.867-3.691) and a 4.251-fold (OR = 4.251, 95% CI = 2.466-7.328) increase, respectively, in the likelihood of having low HRQoL. Surprisingly, the study did not find a significant link between ORB levels and obesity, and obesity status did not predict a higher probability of low HRQoL.
CONCLUSIONS: This study underscores the need for tailored interventions designed specifically for children from socioeconomically vulnerable families to address their unique challenges.
CONCLUSIONS: This research provides valuable insights for pediatric nurses and healthcare providers, highlighting the crucial role of promoting healthy ORB in socioeconomically vulnerable children to address disparities in childhood obesity and HRQoL.

UNASSIGNED: Genetic variants that control dopamine have been associated with obesity in children through loss of control of satiety and impulses, the manifestation of addictive eating behaviors, and specific personality traits. The variants include FTO-rs9939609 and the MAO-A 30 pb u-VNTR low-transcription alleles (LTA).
UNASSIGNED: To evaluate the genetic association of FTO-rs9939609 and the MAO-A LTA, along with personality traits and eating behavior with obesity in Mayan children from Mexico.
UNASSIGNED: We cross-sectionally evaluated 186 children (70 with obesity and 116 with normal weight) 6-12 years old from Yucatan, Mexico. Nutritional status was defined with body mass index (BMI) percentiles. Personality traits were evaluated with the Conners and TMCQ tests; eating behavior was evaluated with the CEBQ test. Genotyping with real-time PCR and TaqMan probes was used for FTO-rs9939609, whereas PCR amplification was used for MAO-A u-VNTR.
UNASSIGNED: High-intensity pleasure (p = 0.013) and moderate appetite (p = 0.032) differed according to nutritional status. Heterozygous FTO-rs9939609 T/A children showed higher mean scores of low-intensity pleasure (p = 0.002) and moderate appetite (p = 0.027) than homozygous T/T. Hemizygous boys having MAO-A LTA showed significantly higher mean scores of anxiety (p = 0.001) and impulsivity (p = 0.008). In multivariate models, only LTA alleles of MAO-A explained obesity in boys (OR = 4.44; 95% CI = 1.18-16.63).
UNASSIGNED: In the present study, MAO-A u-VNTR alleles were associated with obesity in multivariate models only in boys. These alleles might also have a role in personality traits such as anxiety and impulsivity, which secondly contribute to developing obesity in Mayan boys.

UNASSIGNED: In patients with diabetes, obesity is an aggravating factor for glycemic control and its vascular complications. However, the psychological and behavioral characteristics of those patients with obesity have not been fully clarified. This study investigated eating and coping behavior, personality traits, quality of life (QOL), and depression status in patients with diabetes with or without obesity.
UNASSIGNED: Questionnaires obtained from 567 patients with diabetes at Dokkyo Medical University were analyzed. Eating behavior, coping behavior, personality traits, QOL, and depression status were evaluated by the Eating Behavior Questionnaire, Brief COPE, Japanese Ten-Item Personality Inventory, EuroQol 5 Dimensions-5 Level, and Patient Health Questionnaire-9, respectively. Participants were divided according to body mass index (BMI) into a non-obese group (BMI < 25), obese group (BMI 25-35), and high-degree obese group (BMI ≥ 35), and results were compared between groups.
UNASSIGNED: On all items of the Eating Behavior Questionnaire, scores were higher in the obese and high-degree obese groups than non-obese group, indicating worse eating behavior. In coping behavior, significant intergroup differences were found in self-distraction, substance use, using emotional support, using instrumental support, and venting. As for personality traits, the obese group had significantly lower conscientiousness and higher emotional instability than the non-obese group. There was no significant difference in QOL or depression status.
UNASSIGNED: These results suggest that there are some characteristics in eating and coping behaviors and some personality traits between obese and non-obese patients with diabetes. Treatment based on such characteristics may be useful for patients with diabetes and obesity.
