Food Avoidance beyond the Gluten-Free Diet and the Association with Quality of Life and Eating Attitudes and Behaviors in Adults with Celiac Disease

Background: The only treatment for Celiac Disease (CeD), which affects about 1% of the population, is a gluten-free diet (GFD). Studies have indicated an association between the GFD, a diminished quality of life (QOL), and maladaptive eating patterns. This study aims to explore food avoidance behaviors in adults with CeD. Methods: This cross-sectional study assessed 50 adults with biopsy-confirmed CeD who completed validated surveys evaluating demographics, psychological factors, QOL, eating pathology, and food avoidance. Results: Overall CDQOL scores were good (mean: 62.7 out of 100). However, 58.0% of the participants self-elected to avoid one or more additional foods without diagnosed allergies or intolerances. Those avoiding one or more other foods had lower QOL scores (57.4 (23.2) vs. 70.2 (15.9)) compared to those only avoiding gluten (p = 0.034). The mean depression score (CESD) for the group avoiding foods beyond gluten was in the depressive range, unlike those avoiding only gluten (16.0 (4.9) vs. 13.6 (4.0), p = 0.078), with 77% of those avoiding more than gluten scoring above the CESD cut-off point of 15, indicating clinical depression. Conclusions: Over half of participants (58%) reported avoiding additional foods beyond the GFD, a behavior associated with decreased QOL and increased depression.

Negative emotional eating patterns in Chinese adolescents: A replication and longitudinal extension with latent profile and transition analyses

This study, which is a longitudinal extension of previous cross-sectional studies in Chinese and American college students and general adults (Dixit et al., 2023; He et al., 2020; Xu et al., 2024), used latent profile and latent transition analyses to investigate negative emotional eating patterns and the stability of these patterns in 1462 Chinese adolescents (41% boys, aged 11−17 years) at baseline and 18 months later. We also explored baseline demographic predictors of negative emotional eating patterns and the associations between these patterns and outcome variables measured 18 months later. Negative emotional eating was measured with the Adult Eating Behavior Questionnaire (emotional undereating and emotional overeating subscales). Latent profile analysis (LPA) replicated the four patterns of negative emotional eating in each wave of assessment: low emotional eating (Low-EE), emotional overeating (EOE), emotional undereating (EUE), and emotional over- and under-eating (EOE-EUE). Latent transition analysis (LTA) showed that the EE patterns had transition probabilities of <55% remaining in the same class across 18 months. Furthermore, relative to adolescents in the stable Low-EE group, adolescents in all other stable or unstable emotional eating groups in LTA were linked to higher eating disorder psychopathology and psychological distress measured 18 months later. Thus, emotional eating, regardless of type (i.e., EOE, EUE, and EOE-EUE) and stability (i.e., stable or unstable), may be a viable research and treatment target in improving adolescents’ eating behaviors and mental health.

The association between appetite and eating behaviors among Chinese female university students

BackgroundYoung females are at a higher risk of developing unhealthy eating behaviors. This study investigated the relationship between appetitive traits and eating behaviors among female university students. MethodsThe study participants were 520 female university students from a public university in Eastern China. Appetitive traits were assessed using the Chinese version of the Adult Eating Behavior Questionnaire (C-AEBQ). Data on eating behaviors, including food intake frequency, meal regularity, and dieting behavior, were collected using self-administered questionnaires. The body mass index (BMI) was calculated using self-reported data. Pearson's and Spearman's correlations were used to correlate appetitive traits with BMI and eating behaviors. Latent profile analysis (LPA) was used to identify different appetitive patterns, and logistic regression was used to analyze the relationship between different appetitive patterns and eating behaviors. ResultsTwo food-approach traits (food enjoyment and emotional over-eating) were positively correlated with BMI, while two food-avoidance traits (slowness in eating and satiety responsiveness) showed negative correlations. Food responsiveness was linked to a higher intake of delivered food, spicy food, and sugar-sweetened beverages, whereas satiety responsiveness was correlated with more frequent meal skipping. The LPA identified four appetitive patterns: food approachers, food approachers with emotional under-eating, food avoiders, and food avoiders with emotional over-eating. Food avoiders had significantly lower BMI than the other groups. Compared to food approachers, food avoiders skipped breakfast more frequently, and food avoiders with emotional over-eating skipped both breakfast and lunch more often. After adjusting for BMI, appetitive patterns showed no significant relationship with dieting behavior. ConclusionAmong female university students, appetitive patterns correlated with eating behaviors, and students with food-avoidance patterns had a higher risk of meal irregularity. These findings emphasize the importance of implementing trait- and pattern-specific approaches to promote healthy eating behaviors among female university students.

Validation of the Adult Eating Behavior Questionnaire (AEBQ) in a young adult Black sample in the U.S.: Evaluating the psychometric properties and associations with BMI

The Adult Eating Behavior Questionnaire (AEBQ) is an instrument developed in the UK and used to examine appetitive traits in adults. The AEBQ is divided into four Food Approach subscales, namely; Enjoyment of Food, Emotional Overeating, Food Responsiveness and Hunger, and four Food Avoidance subscales, namely; Emotional Undereating, Food Fussiness, Slowness in Eating, and Satiety Responsiveness. The instrument has been validated in a number of countries. However, there is limited evidence to show the validation of the AEBQ in predominantly Black populations. The aim of this cross-sectional study was to validate the AEBQ in a Black young adult sample in the U.S.A. Participants (n = 229) consisted of young adults with an average age (20.97 ± 4.31) attending a Central Virginia Historically Black University. Reliability Analysis and Confirmatory Factor Analysis (CFA) were conducted. Correlations, as well as multivariate multiple linear regression models were estimated. Food Avoidance subscales demonstrated more internal consistency than the Food Approach subscales. The CFA results indicated a 7-factor model in which the Hunger subscale was eliminated to fit the data better overall. The Food Approach subscales demonstrated more convergent validity than the Food Avoidance subscales. BMI significantly predicted both Emotion Overeating and Emotional Undereating, as well as Food Fussiness. Moreover, both sex and age significantly predicted Emotional Undereating, Food Responsiveness and Hunger. Further, sex significantly predicted Emotional Overeating and Satiety Responsiveness. Lastly, depression predicted Emotional Undereating. In conclusion, this study provided some evidence to support the use of the AEBQ as a reliable and valid measure of adult eating behavior.

The significance of cultural context in the classification of preferred mouth behavior: Exploring eating behavior using causal network analysis

AbstractPreferred mouth behavior studies have mostly focused on Western populations using the JBMB tool to determine how food is manipulated in the mouth. The objective of this study was to determine the relationship between preferred mouth behavior and eating behavior among the diverse group of 209 Malaysians participants. A series of Analysis of Variances and an unsupervised machine learning technique known as Latent Class Clustering were utilized to determine individual's oral behavior. The Adult Eating Behavior Questionnaire was later modeled using causal networks, specifically Partial Least Squares‐Confirmatory Factor Analysis, to uncover relationship between appetitive qualities. The results from this study showed that cultural context and appropriateness play an essential role when classifying preferred mouth behavior using behavioral questionnaires and models. Furthermore, this study also determined the relationship between eating behavior and preferred mouth behavior, as well as unique differences in eating behavior observed among the mouth behavior groups.

Exploring Adult Eating Behaviors and Food Neophobia: A National Study in Romania.

Food neophobia involves avoiding new foods due to reluctance, aversion, or disgust. The Food Neophobia Scale (FNS) is the most reliable and common adult food neophobia test. It helps compare food neophobia across cultures by being translated into numerous languages. This study adapted, translated, and validated the FNS for Romania. This translated version was piloted in November 2023 on 59 students in the medical field from two distinct Romanian cities. Between December 2023 and February 2024, 375 adults were surveyed, representing Romania's population within a 90% confidence interval. The average age of responders was 38.07 years, with a standard deviation of 10.75 and a 4:1 female-to-male sex ratio. The Cronbach's alpha test was used to validate the questionnaire. Our study found that the mean FNS value was 31.86; most Romanian respondents (69.20%) were neutral towards trying new foods, with a significant portion being neophobes (18.21%) outnumbering neophiles (12.59%). When compared to international study results, Romanian adults, on average, exhibited a higher percentage of neophobes compared to those in Korea (13%), Hungary (16.8%), Italy (17%), and Brazil (17.5%), but a lower percentage than those in Lebanon (21.5%). The findings indicate that the translated scale can be utilized to assess neophobia among Romanian speakers.

Validation of the Adult Eating Behavior Questionnaire in an Italian Community Sample.

(1) Background: Appetitive traits in adults can be measured through the Adult Eating Behavior Questionnaire (AEBQ), a questionnaire adapted from the Child Eating Behavior Questionnaire (CEBQ). The AEBQ has been validated in several countries. The aim of the present study was to explore and validate the factor structure of the Italian version of the AEBQ. Furthermore, convergent validity and correlations between factors and BMI were explored to assess its criterion validity. (2) Methods: Participants (N = 624, mean age of 32.08 ± 14.94 years) completed the AEBQ, the Eating Attitude Test (EAT-40), and the Dutch Eating Behavior Questionnaire (DEBQ). They also self-reported demographic and anthropometric data. A Confirmatory Factor Analysis (CFA) was used to test three different alternative models that emerged in previous validations. (3) Results: The CFA revealed a good model fit (RMSEA = 0.0634, TLI = 0.894, CFI = 0.907) for the 7-factor structure, without the Hunger items, showing a valid and reliable (Cronbach's α > 0.7) structure. Convergent and divergent validity of the AEBQ yielded favorable results, and relationships between the AEBQ and BMI factors revealed that the Food Approach traits were positively associated with BMI. (4) Conclusions: Finally, this study provides initial support for the use of the AEBQ as a valid and reliable tool to measure a wide range of appetitive traits in the adult Italian population.

Examining measurement invariance of appetitive trait and ARFID symptom measures by food security status

ObjectiveMeasures assessing appetitive traits (i.e., individual differences in the desire to consume food) and disordered eating have generally been developed in predominantly food-secure populations. The current study aims to test measurement invariance (MI) for a measure of appetitive traits and a measure of Avoidant Restrictive Food Intake Disorder (ARFID) symptomology across food security status. MethodData from a sample of mothers (n = 634) and two undergraduate samples (n = 945 and n = 442) were used to assess MI for the Adult Eating Behavior Questionnaire (AEBQ), which measures appetitive traits, and the Nine Item ARFID Screen (NIAS), which measures ARFID symptomology. Current food security was assessed using the 18-item USDA Household Food Security Survey Module, which was dichotomized into two groups: 1) the ‘food insecure’ group included marginal, low, and very low food security and 2) the ‘food secure’ group included high food security. Overall and multi-group confirmatory factor analyses were conducted separately for each measure in each sample. ResultsResults demonstrated scalar (i.e., strong) MI for both measures across samples, indicating that these measures performed equivalently across food-secure and food-insecure individuals. ConclusionFindings suggest that differences in appetitive traits by food security status observed in prior research are not artifacts of measurement differences, but instead reflect true differences. Additionally, past mixed results regarding the relationship between food insecurity (FI) and ARFID symptomology are not likely driven by measurement error when using the NIAS.

Your Body Is Your Home: The feasibility of an intuitive eating intervention for early adolescents.

Intuitive eating (IE) is an emerging health promotion framework which has shown promise in the prevention and early intervention of disordered eating (DE) behavior in adults. This study sought to extend this work by assessing the feasibility and preliminary efficacy of a 5-week IE intervention, "Your Body is Your Home," delivered in school classrooms for early adolescents aged 11-13. The present study utilized a quasi-experimental design. Eligibility criteria were defined a priori and published in a registered protocol. Four classrooms (n = 128 student participants) were recruited into two streams, and self-report questionnaires were administered at pre-test, post-test, and 4-week follow-up. The questionnaires included the Intuitive Eating Scale for Early Adolescents (IES-2-EA), the Body Appreciation Scale (BAS-2), and the WHO Wellbeing Index (WHO-5). Linear mixed models were used to conduct preliminary efficacy testing. The results indicate that a brief classroom-based IE intervention is feasible and acceptable for both students and teaching staff; retention, fidelity, and attendance targets were achieved. Students and teachers rated all five sessions of the intervention as a highly feasible method of health promotion. Further, preliminary efficacy data suggest IE interventions aimed at early adolescents may be a feasible way of improving certain aspects of IE (p < .001) in male and female participants, and body appreciation (p < .001) in male participants. The study provides preliminary support for the implementation and evaluation of an IE intervention as part of school-based health promotion and offers preliminary effect size estimates for a larger-scale randomized trial. Existing evidence suggests that IE may be a useful framework through which relationships with food and the body can be improved. The present study seeks to extend this work by adapting the framework for early adolescents (among whom the framework is not well understood) and examining feasibility, acceptability, and preliminary changes to several health and well-being metrics following a 5-week school-based intervention.

Assessing the relationship between nutrition literacy and eating behaviors among nursing students: a cross-sectional study

BackgroundEating behavior is an essential aspect of life that can have long-term effects on health outcomes. Nutrition literacy is crucial for better health and well-being. It empowers individuals to make informed decisions about their nutrition and take control of their eating habits.ObjectivesThis study aimed to assess the relationship between nutritional literacy and eating behavior among nursing students at the nursing faculties of Ardabil University of medical sciences.MethodsA cross-sectional correlational study was conducted in Ardabil province, northwest Iran. The study collected data through simple random sampling at nursing schools in Ardabil province, with 224 nursing students participating. The study collected data from a demographic information form, the nutritional literacy self-assessment questionnaire for students (NL-SF12), and the adult eating behavior questionnaire (AEBQ). The data were analyzed using SPSS version 14.0 software.ResultsBased on the results, nutritional literacy explains 44% of the variance in eating behavior and shows significant explanatory power in two sub-scales of eating behavior. The adjusted R2 values for food approach and food avoidance scales were 0.33 and 0.27, respectively.ConclusionGiven the significant relationship between nutritional literacy and eating behaviors among nursing students, nursing faculty managers and health policymakers should develop new public health strategies to increase nutritional literacy among nursing students.

Validation of the adult eating behavior questionnaire in a Norwegian sample of adolescents

Eating behaviors are related to health and well-being. To examine stability and change in eating behaviors throughout life, developmentally appropriate measures capturing the same eating behavior dimensions are needed. The newly developed Adult Eating Behavior Questionnaire (AEBQ) builds on the well-established parent-reported Children's Eating Behavior Questionnaire (CEBQ), and together with the corresponding Baby Eating Behavior Questionnaire (BEBQ), these questionnaires cover all ages. However, validation studies on adolescents are relatively sparse and have yielded somewhat conflicting results. The present study adds to existing research by testing the psychometric properties of the AEBQ in a sample of 14-year-olds and examining its construct validity by means of the parent-reported CEBQ. The current study uses age 14 data (analysis sample: n = 636) from the ongoing Trondheim Early Secure Study, a longitudinal study of a representative birth cohort of Norwegian children (baseline: n = 1007). Confirmatory factor analysis (CFA) was conducted to test the factorial validity of AEBQ. Construct validity was examined by bivariate correlations between AEBQ subscales and CEBQ subscales. CFAs revealed that a 7-factor solution of the AEBQ, with the Hunger scale removed, was a better-fitting model than the original 8-factor structure. The 7-factor model was respecified based on theory and model fit indices, resulting in overall adequate model fit (χ2 = 896.86; CFI = 0.924; TLI = 0.912; RMSEA = 0.05 (90% CI: 0.043, 0.051); SRMR = 0.06). Furthermore, small-to-moderate correlations were found between corresponding AEBQ and CEBQ scales. This study supports a 7-factor solution of the AEBQ without the Hunger scale and provide evidence of its construct validity in adolescents. Several of the CEBQ subscales were significantly associated with weight status, whereas this was the case for only one of the AEBQ scales.

Mediating role of weight concerns in the relationship between seasonality and eating behavior among community-dwelling older adults: A path analysis

BackgroundWeight concerns are common among older adults, and it is unclear how they may impact the relationship between seasonality and eating behaviors, which can contribute to various health-related issues. AimThis study investigated the mediating role of weight concerns in the relationship between seasonality and eating behavior among community-dwelling older adults. MethodA descriptive correlational analytical design was used on 200 randomly chosen participants who completed the Personal Inventory for Depression and Seasonal Affective Disorder Self-Assessment Version, the Adult Eating Behavior Questionnaire, and the Weight Concern Subscale. A path analysis was conducted to test the hypothesized model. ResultsThe study findings indicated that most older adults reported moderate-to-severe seasonal variations, moderate enjoyment of food, emotional overeating, emotional undereating, and food fussiness. Weight concern partially mediated the relationship between seasonality and eating behavior. ConclusionBy understanding the complex interplay between these factors, weight concerns may play an essential role in mediating the effects of seasonal changes on eating behavior, while seasonal winter symptoms may directly impact eating behavior. These results have potential implications for nurses' efforts to develop interventions to promote healthy eating behaviors and manage weight concerns during seasonal variations, especially in the winter.

Postprandial Increases in Liver-Gut Hormone LEAP2 Correlate with Attenuated Eating Behavior in Adults Without Obesity.

The novel liver-gut hormone liver-expressed antimicrobial peptide-2 (LEAP2) is a centrally acting inverse agonist, and competitive antagonist of orexigenic acyl ghrelin (AG), at the GH secretagogue receptor, reducing food intake in rodents. In humans, the effects of LEAP2 on eating behavior and mechanisms behind the postprandial increase in LEAP2 are unclear, though this is reciprocal to the postprandial decrease in plasma AG. Plasma LEAP2 was measured in a secondary analysis of a previous study. Twenty-two adults without obesity attended after an overnight fast, consuming a 730-kcal meal without or with subcutaneous AG administration. Postprandial changes in plasma LEAP2 were correlated with postprandial changes in appetite, high-energy (HE) or low-energy (LE) food cue reactivity using functional magnetic resonance imaging, ad libitum food intake, and plasma/serum AG, glucose, insulin, and triglycerides. Postprandial plasma LEAP2 increased by 24.5% to 52.2% at 70 to 150 minutes, but was unchanged by exogenous AG administration. Postprandial increases in LEAP2 correlated positively with postprandial decreases in appetite, and cue reactivity to HE/LE and HE food in anteroposterior cingulate cortex, paracingulate cortex, frontal pole, and middle frontal gyrus, with similar trend for food intake. Postprandial increases in LEAP2 correlated negatively with body mass index, but did not correlate positively with increases in glucose, insulin, or triglycerides, nor decreases in AG. These correlational findings are consistent with a role for postprandial increases in plasma LEAP2 in suppressing human eating behavior in adults without obesity. Postprandial increases in plasma LEAP2 are unrelated to changes in plasma AG and the mediator(s) remain uncertain.

Patterns of Eating Behavior among 13-Year-Old Adolescents and Associated Factors: Findings from the Generation XXI Birth Cohort.

Eating behavior adopted during adolescence may persist into adulthood. The aims of this study were to identify eating behavior patterns among Portuguese adolescents and to explore whether groups differ in terms of early life and family characteristics, severity of depressive symptoms, and body mass index (BMI) z-score. Participants were 3601 13-year-olds enrolled in the birth cohort Generation XXI. Eating behavior was assessed using the self-reported Adult Eating Behavior Questionnaire (AEBQ), validated in this sample. The severity of depressive symptoms was measured through the Beck Depression Inventory (BDI-II), and data on sociodemographic and anthropometrics were collected at birth and 13-years-old. Latent class analysis was conducted, and associations were estimated using multinomial logistic regression models. Five patterns of individuals were identified: "Picky eating", "Disinterest towards food", "Food neophilia", "Emotional eating", and "Food attractiveness". The adolescents' sex, maternal education, BMI z-score, and severity of depressive symptoms were significantly associated with the identified patterns. In particular, adolescents with a higher BMI z-score were more likely in "Food neophilia" while individuals with more severe depressive symptoms were in the "Picky eating", "Emotional eating", and "Food attractiveness" patterns. These findings suggest a starting point for the development and planning of targeted public health interventions.

Negative emotional eating patterns among American university students: A replication study

Emotional eating (EE) has been consistently associated with obesity, weight gain, and certain eating disorders (EDs). Given the cultural influence on food consumption and eating styles, comparison of EE patterns of individuals in culturally distinct nations (e.g., USA and China) could yield interesting differences in findings. However, given the increasing convergence in eating practices between the above-mentioned nations (e.g., higher reliance on outdoor eating at restaurants among Chinese adolescents), EE patterns might share significant similarities. The present study examined EE patterns of American college students and is a replication of the study done by He, Chen, Wu, Niu, and Fan (2020) on Chinese college students. Responses of 533 participants (60.4% women, 70.1% White, aged 18–52 (mean age = 18.75, SD = 1.35), mean self-reported body mass index = 24.22 kg/m2 and SD = 4.77) on the Adult Eating Behavior Questionnaire (Emotional overeating and emotional undereating subscales) were examined using Latent Class Analysis to identify specific patterns of EE. Participants also completed questionnaire measures of disordered eating and associated psychosocial impairment, depression, stress, and anxiety symptoms, and a measure of psychological flexibility. A solution with four classes emerged, i.e., emotional over- and undereating (18.3%), emotional overeating (18.2%), emotional undereating (27.8%), and non-emotional eating (35.7%). Current findings replicated and extended findings from He, Chen, et al. (2020) in that the emotional over- and undereating class exhibited the highest risks for depression, anxiety, stress, and psychosocial impairment due to disordered eating symptoms as well as lower psychological flexibility. Individuals who have difficulty with awareness and acceptance of their emotions appear to engage in the most problematic form of EE and could benefit from Dialectical behavior therapy and Acceptance and commitment therapy skills training.

Exploring differences in disordered eating and related appetitive traits among women based on childhood and current food security status

Despite emerging evidence that food insecurity (FI) is associated with elevated rates of eating pathology, little is known about the lasting impact of FI on eating behaviors. Studies that have explored the association between FI during childhood and eating behavior in adulthood have not accounted for current FI. The present study explored differences in disordered eating (DE) and related appetitive traits among four groups of cisgender female mothers: individuals who (1) endorsed childhood FI only (n = 96), (2) endorsed current FI only (n = 134), (3) endorsed both childhood and current FI (n = 257), and (4) denied both childhood and current FI (n = 146). Participants responded to online questionnaires including items from the USDA Household Food Security Survey Module, the 7-item Eating Disorder Examination-Questionnaire, the Eating Disorder Diagnostic Scale, and the Adult Eating Behavior Questionnaire. Adjusting for age and race/ethnicity, ANCOVAs explored mean differences between groups in DE and appetitive traits, and a modified Poisson regression model examined differences in binge-eating prevalence across the four FI groups. The “current FI only” group consistently endorsed the highest levels of DE and related appetitive traits followed by the “current and childhood FI” group, suggesting newly food-insecure women may be at highest risk for DE. Interestingly, across almost all constructs, the “childhood FI only” group did not differ significantly from the “no FI” group. These findings suggest that improved access to food may help offset risk for adult DE related to experiences of FI in childhood.

The role of stress in the association among food insecurity, eating disorder pathology, and binge eating-related appetitive traits

PurposeGrowing literature demonstrates a positive association between food insecurity (FI) and eating disorder pathology. Additionally, FI has been associated with two appetitive traits strongly linked to binge eating, food responsiveness and emotional overeating. However, little research has investigated factors that might help to explain these associations. One hypothesis is that experiencing FI may increase stress, and that eating disorder pathology, particularly binge eating-related phenotypes, may serve as a coping strategy. This study explores stress as a potential mechanism in the association between FI and general eating disorder pathology, as well as two appetitive traits strongly associated with binge eating (food responsiveness and emotional overeating). MethodsCis-gender women (N = 634) completed online questionnaires assessing FI, stress, eating disorder pathology (measured via the total score on the Short Eating Disorder Examination Questionnaire), and binge eating-related appetitive traits (measured via the Adult Eating Behavior Questionnaire). Cross-sectional indirect effects analyses with a 1000-sample bootstrap were used to test pathways among FI, stress, and eating-related constructs. ResultsFI was significantly associated with eating disorder pathology and associated appetitive traits (ps < 0.001). Stress explained a significant proportion of the correlation between FI and each eating-related construct. ConclusionsOur findings extend prior research on the relationships between FI, eating disorder pathology, and binge eating-related appetitive traits to provide preliminary evidence that stress may act as an underlying mechanism. Future studies should use longitudinal designs to assess the prospective relationships among these constructs.

Effect of Mid-Adolescent Dietary Practices on Eating Behaviors and Attitudes in Adulthood

This paper aimed to clarify the association of mid-adolescent dietary practices and experiences with adult eating behavior and attitudes using individual data from the "Survey of Attitudes toward Shokuiku (food and nutrition education), 2019" put forth by the Ministry of Agriculture, Forestry and Fisheries of Japan. We applied conditional mixed-process models to estimate the parameters simultaneously, and used them to predict current eating consciousness, current eating behaviors in a balanced diet, dietary behavior, and attitudes toward preventing or improving lifestyle-related diseases as dependent variables. As a result, compared to those who did not have good dietary practices and experiences in mid-adolescence, participants who had good dietary practices and experiences in the same period displayed greater interest in practicing a healthier diet. These participants frequently consumed a combination of staple foods, main dishes, and side dishes, and were more concerned about preventing or improving lifestyle-related diseases. In conclusion, mid-adolescent dietary practices and experiences had a lasting influence on adult eating behaviors and attitudes in Japanese participants.

Eating behaviors, dietary patterns and weight status in emerging adulthood and longitudinal associations with eating behaviors in early childhood

BackgroundEating behaviors may contribute to differences in body weight and diet over time. Our study aims to examine how eating behaviors of young adults relate to their current weight status and dietary patterns and to explore longitudinal associations with eating behaviors in early childhood.MethodsStudy participants are young adults (n = 698) taking part in the Quebec Longitudinal Study of Child Development. At age 22, eating behaviors were assessed using the Adult Eating Behavior Questionnaire. Dietary patterns were derived from information collected by food frequency questions. Weight status was based on self-reported data. Information on eating behaviors in childhood had been collected when participants were 2.5 to 6 years old. Pearson’s correlations were used to determine associations between adult eating behaviors and body mass index. Simple and multivariate linear regression analyses were used to examine associations between eating behaviors and dietary patterns at age 22, and longitudinal associations with behaviors in early childhood. Ordinal logistic regression analyses were used to assess associations between overeating and fussy eating in childhood and weight status at age 22.ResultsBody mass index was positively correlated with Emotional overeating, Enjoyment of food, and Food responsiveness and negatively correlated with Satiety responsiveness, Emotional undereating, Slowness in eating and Hunger. A Healthy dietary pattern was positively associated with both Enjoyment of food and Hunger, and negatively associated with Food fussiness. Inversely, a Beverage-rich dietary pattern was negatively associated with Enjoyment of food and positively associated with Food fussiness. A Protein-rich pattern was positively associated with Enjoyment of food, while a High energy density pattern was positively associated with Food fussiness. Young adults with higher scores for fussy eating in early childhood were more likely to manifest Food fussiness and Emotional undereating, and less likely to adopt a Healthy dietary pattern. Young adults with higher scores for overeating in early childhood were less likely to show traits such as Slowness in eating and more likely to be overweight.ConclusionsOur findings suggest that eating behaviors in childhood have long-term influence on diet and weight status, thereby reinforcing the importance of early interventions that promote healthy eating.
