Combined Insights from Leachate Structure and Microstructure Characteristics for Eating Quality of Convenience Rice Processed by Super-Heated and Pressurized Steam Technologies

Convenience rice has become widely popular due to its easy availability for cooking. This study investigated the starch structure and composition of leachate and the microstructure of reheated convenience rice using novel processing technologies: super-heated steaming(SHS), auto-electric cooking(AEC), and pressurized-steam cooking(PSC). Additionally, the effect of two different target water contents(58% and 63%) was also evaluated. The PSC_63% sample had the highest total solids and amylopectin amount in the leachate. The amylopectin amount in the leachate differed significantly based on the targeted water content. Morphological characterization revealed that the swelling of starch and the coated layer on the surface of rice grains were most pronounced in the PSC_63% sample due to the pressure processing. The textural hardness of the AEC_58% sample was much higher than that of the other samples. The PSC_63% sample had the highest textural adhesiveness value, which can be attributed to the highest amylopectin amount in the leachate. Sensory characterization showed that the PSC_63% sample had the highest glossiness, whiteness, moistness, and overall acceptability. The principal component analysis score plots presented substantial differences in the leachate and textural and sensory characteristics of reheated convenience rice among the different processing technologies.

Eating Disorders and Pregnancy: The Case of Anorexia

The question of the link between pregnancy and eating disorders is an important question. At the moment, there are few concrete answers for these patients. Despite common fertility challenges, patients who suffer from ED are able to access maternity. ED and pregnancy can either have an easy evolution or experience a lot of trouble. Many studies describe obstetrical and foetal complications (low birthweight, inadequate intra-uterine growth, small head circumference, miscarriage, caesarean section). Those patients are frequently reluctant to address their disease with their specialist, who also often doesn’t know how to screen the signs. The lack of official data to train the specialists further increases these difficulties. However, ED are frequent in the general population and young patients are likely to eventually want to become mothers. It is thus essential to know how to screen those patients early and accurately to improve their treatment and care. Eating disorders impact the pregnancy, the delivery and the postpartum as well as the growth of the baby. It is an important public health problem. The evolution from being a woman to becoming a mother is a difficult one, and even more so when the women is suffering from ED. Those patients must handle their nutritional fears, the anxiety about their body changing with pregnancy and the daily challenges. The early interactions with their baby have consequences on their development. It seems necessary to evaluate how to improve the screening and the patient care in ED patients. Screening should begin from the pregnancy desire to the postpartum. This patient care should be based on a multidisciplinary care team.

Racial and Ethnic Differences in Orthorexia Nervosa Symptomatology and Other Disordered Eating

While some research has explored racial and ethnic differences in disordered eating, this study may be the first to examine these differences in orthorexia nervosa, involving obsessive-compulsive thoughts and behaviors concerning healthy eating, which negatively impact one’s life. Adult participants, recruited from college courses and social media, completed an online survey with the Orthorexia Nervosa Inventory (ONI) and the Eating Attitudes Test-26 (EAT-26). Regarding racial and ethnic background, 743 were White, 249 were Hispanic, 87 were Black, 61 were Asian or Pacific Islander, and 110 were biracial/multiracial. A MANCOVA revealed that the racial and ethnic groups did not differ on the ONI subscales assessing orthorexic behaviors, impairments, and emotions, after accounting for gender, BMI, and EAT-26 total scores that were covariates. In contrast, a second MANCOVA did reveal group differences on the EAT-26 subscales, after accounting for gender, BMI, and ONI total scores that were covariates. Black participants scored significantly lower than the other racial and ethnic groups on the subscale assessing dieting behaviors characteristic of anorexia nervosa, and the subscale assessing binge-eating and purging behaviors characteristic of bulimia nervosa. Further, Hispanic participants scored significantly lower than White participants on the latter subscale. These findings suggest that while orthorexic symptomatology does not differ based on race and ethnicity, a Black race and Hispanic ethnicity may be protective factors against disordered eating, perhaps related either to cultural norms concerning body image or to the resiliency and social support among the Black and Hispanic communities.

Biopsychosocial Review of Eating Disorders

Eating disorders are among the deadliest mental illnesses known to occur. Eating disorders directly cause 10,200 deaths each year, which is one death every 52 minutes. About 9% of the global population is affected by eating disorders at some point during their lifetime. This paper aims to provide a better understanding of the factors that contribute to the onset of eating disorders. Specifically, we examine biological factors, such as genetics, family history and the neuroscience behind eating disorders;furthermore, we explore psychological factors including other mental health conditions and their correlation, personality traits and behavioral risk factors;lastly, we consider social factors related to the onset of eating disorders, such as childhood and social environment, the media, and demographic factors.

Eating Disorders among Students in Northern Benin (2023)

Introduction: From their earliest hours, human beings are able to identify a source of food and to feed themselves. Feeding is therefore one of the most instinctive human functions. It is regulated by several factors (physiological, psycho-affective and environmental) whose disruption can lead to eating disorders. Objective: The aim of this study was to investigate eating disorders among students in the town of Parakou in 2023. Method: Descriptive cross-sectional study conducted from January to July 2023 in various universities in the city of Parakou, Benin. The study population consisted of all students in grades 1 to 7 at these universities. A two-stage non-proportional stratified sampling technique combined with a simple random draw was adopted. The Eating Attitude Test-26, Bulimia Inventory Test Edinburgh and a set of questions focusing on the diagnostic criteria for pica were used to screen for pica and other disorders such as anorexia, bulimia nervosa and binge eating disorder. Data were analyzed using SPSS (Statistical Package for Social Sciences) version 25. Results: A total of 607 students were surveyed, 323 of whom had eating disorders. A prevalence of 53.21% of students at risk of eating disorders was found. In relation to the total population, the prevalences of anorexia, bulimia nervosa, binge eating disorder and pica were 45.96%, 0.82%, 15.48% and 12.68% respectively. In multivariate analysis, seven factors explained the risk to develop at least one eating disorder among the students surveyed. These were: urban area of residence (OR (95% CI) = 5.059 (1.75 - 14.65);p = 0.003);year of study (OR (95% CI) = 0.47 (0.28 - 0.79);p = 0.035);type of university attended (private university: OR (95% CI) = 1.63 (1.08 - 2.44);p = 0.019);parents’ marital status (couple or not) (OR (95% CI) = 1.50 (1.01 - 2.24);p = 0.046);father’s level of education: secondary (OR (CI 95%) = 3.85 (1.96 - 7.54);p 0.001)/higher (OR (CI 95%) = 2.83 (1.36 - 5.86);p = 0.005);mother’s one: secondary (OR (CI 95%) = 0.30 (0.18 - 0.51);p 0.001)/superior (OR (CI 95%) = 0.31 (0.16 - 0.61);p = 0.001);the presence of doubtful (OR (CI95% = 1.69 (1.11 - 2.58);p = 0.009) or certain anxiety symptomatology (OR (CI 95%) = 1.69 (1.11 - 2.58);p = 0.009). Conclusion: More than half the students in Parakou had at least one eating disorder. Diagnostic studies are needed, even if preventive actions are already necessary.

Advances in the Study of Psychological Stress and Eating Behavior in Children and Adolescents

With the rapid development and change in society,children and adolescents are facing more and more psychological pressure,which comes not only from academic performance and interpersonal relationships but also from family environment,social expectations and other aspects.Psychological stress not only affects the mental health of children and adolescents but is also closely related to their eating behavior.Therefore,exploring the relationship between psychological stress and eating behaviors is of great significance in promoting the physical and mental health development of children and adolescents.Based on this,the study reviewed the research progress on the relationship between psychological stress and eating behavior of children and adolescents in recent years.The relationships between psychological stress and general eating behaviors,abnormal eating behaviors and eating disorders were successively reviewed,and the related physiological mechanisms were explored with a view to providing a scientific basis for mental health education and eating behavior intervention for children and adolescents.

A causal model of eating behaviors among Thai pregnant women working in industrial factories

Objective:This study aimed to examine the causal model of eating behaviors among pregnant women working in industrial factories.Methods:This cross-sectional study was conducted on 210 participants,attending 4 healthcare centers,at a tertiary care hospital in Chonburi province,Thailand.Data were collected using 7 questionnaires:demographic form,eating behavior questionnaire,perceived benefits of the healthy eating questionnaire,perceived barriers to the healthy eating questionnaire,perceived self-efficacy questionnaire,social support questionnaire,and accessibility to healthy foods questionnaire.Descriptive statistics and path analysis were used for data analysis.Results:The participants had relatively high mean scores for eating behaviors.The final model fitted well with the dataχ^(2)=12.86,df=10,P=0.23;χ^(2)/df=1.29;comparative fit index(CFI)=0.98;goodness-of-fit index(GFI)=0.98;adjusted goodness-of-fit index(AGFI)=0.95;root mean square error of approximation(RMSEA)=0.04.Four factors-perceived benefits(β=0.13,P<0.05),perceived self-efficacy in healthy eating(β=0.22,P<0.001),pregnancy planning(β=0.28,P<0.001),and accessibility to healthy foods in the factory(β=0.12,P<0.05)-positively affected eating behavior,while only perceived barriers to healthy eating had a negative effect on eating behavior(β=−0.24,P<0.001).All the above factors explained 27.2%of the variance in eating behaviors.Conclusions:Nurses or healthcare providers can apply these findings to create an eating behavior modification program,focusing on pregnancy planning,behavior-specific variables,and interpersonal and situational influence,to promote the nutritional status of pregnant women working in industrial factories.

Analysis of the Relationship between Eating and Swallowing Function and Lifestyle of the Elderly Living in the Community-A Secondary Publication

Objectives:The relationship between eating and swallowing function,and lifestyle among community-dwelling elderly people has not been extensively studied.This study aimed to analyze the characteristics of eating and swallowing function and their association with the lifestyle among the elderly.Methods:A self-administered questionnaire survey was conducted on 419 elderly people who participated in the oral function improvement project operated by the Community Comprehensive Support Center.A total of 288 valid responses(58 males,230 females,average age 73.6 years)were analyzed.The survey items included basic demographics,health status,lifestyle,and eating and swallowing functions.The chi-square(χ2)test was used to compare for a difference in the risk of dysphagia.Results:72 patients(25.0%)were judged to be at risk for dysphagia,and 216(75.0%)were judged to be not at risk for dysphagia using the revised dysphagia risk assessment scale.The mean score for oral preparatory dysphagia was the highest,while the mean score for pharyngeal dysphagia was the lowest.The group at risk of dysphagia had significant difficulty in chewing and had bad sleep quality as compared to the group that was not at risk.Conclusion:Concerning the risk of dysphagia,there is a need to maintain and improve masticatory function.In addition,improving the swallowing function of the elderly may prevent insomnia and improve sleep quality.

Psychological flexibility, occupational burnout and eating behavior among working women

Background: Occupational burnout is associated with diminished psychological flexibility and higher emotional (EE) and uncontrolled eating (UE). Psychological flexibility could be a mediating factor between burnout and eating behaviour. Objectives: To investigate differences in eating behaviour between those with different levels of psychological flexibility, and the association of the interaction between psychological flexibility and occupational burnout with eating behaviour. Design: The participants were working women (n = 263), who took part in the randomized controlled health intervention trial. Analyses were performed in a cross-sectional setting at baseline. Methods: Eating behaviour was measured using the Three Factor Eating Behaviour Questionnaire-18 [which evaluates EE, UE and cognitive restraint (CR)], psychological flexibility using Acceptance and Action Questionnaire-II and occupational burnout using Bergen Burnout Indicator-15. Participants were divided into four groups based on the quartile points of psychological flexibility. Results: The EE of those who were inflexible was higher than that of those whose flexibility was high moderate (p = 0.013) and who were flexible (p = 0.001). The UE of those who were inflexible was higher than the UE in the other groups with higher flexibility [low moderate (p = 0.034), high moderate (p een occupational burnout and EE and UE. Multivariate analysis of variances revealed that the combination of psychological flexibility and burnout had a stronger association with the variances of EE and UE than psychological flexibility alone. Conclusions: Persons who are psychologically inflexible have higher EE and UE. Future studies should investigate if increasing psychological flexibility helps decrease EE and UE.

Mapping the landscape and structure of global research on binge eating disorder:Visualization and bibliometric analysis

BACKGROUND Binge-eating disorder(BED)is a clinical syndrome and is considered the most common type of eating disorder.However,our understanding of the global performance and progress of BED research is limited.AIM To describe and perform a bibliometric analysis of the state of BED research.METHODS The term‘Binge eating’was searched in the title throughout the previous year’s up to December 31,2020.We searched the Scopus and Reference Citation Analysis for publications on Binge eating.The VOSviewer software version 1.6.17 was used to produce the network visualization map of the most frequent author,collaborative relationships between countries/regions,and to determine the hotspots related to binge eating research.In addition,conventional bibliometric indicators were generated.RESULTS The search strategy found 2713 total articles and an average of 62 articles per year.Among them,‘Article’represented 82.49%of the publications(n=2238 articles)and was the most frequent type,followed by reviews(n=243;8.96%).The number of publications increased steadily during the last decade of the study period.One hundred and thirty-two countries contributed to binge eating research,with 1495(55.11%)articles published in the United States,followed by Italy with 256(9.44%),the United Kingdom with 183(6.75%),and Germany with 182(6.71%).Currently,the main hot topics related to BED are‘type of treatment and management and treatment provided to BED”;“processes and pathways to binge eating”;and‘diagnosis,signs and symptoms,comorbidities and prevalence and associated factors with BED’.CONCLUSION The number of publications has increased noticeably during the previous decade.There are indeed relatively few publications on BED from low-and middle-income nations,so much is to be learned from the experience of all countries.Studies on this topic are critical in all countries to discover risk factors and effective intervention measures.Although our findings are preliminary,they imply that the future prospects for interventions aimed at BED management are bright,focusing on complex models of care and long-term maintenance of therapeutic gains.

Does food addiction distinguish a specific subgroup of overweight/obese overeating women?

Neurophysiological and behavioral similarities have been evidenced between excessive food consumption leading to obesity and addiction to other substances. In accordance, food addiction was defined following the DSM-IV diagnostic criteria for substance dependence. The aim of this pilot study was to identify a subgroup of women suffering from food addiction (n = 11), and to compare them to women suffering from substance-use disorder (n = 23), and to women seeking treatment for compulsive overeating but free from food addiction (n = 12) on addiction-related characteristics (reward sensitivity, impulsivity, personality traits, depression, emotion dysregulation). We hypothesized that women with food addiction would be similar to women with substance-use disorders, and different from women with compulsive overeating without food addiction. Participants completed self-reported questionnaires assessing food addiction and other variables related to addiction. Almost half (47.8%) of women with compulsive overeating fulfilled the criteria for food addiction. Although food addiction does not account for every case of compulsive overeating, it characterizes a specific subgroup of overweight/obese women who show more severe overeating. Women with food addiction seem to be more similar to women suffering from substance-use disorders than to other women with overeating difficulties, particularly regarding impulsivity and self-directedness.

Normalizing the Neural Correlates of Binge-Eating Disorder with Lisdexamfetamine: A Case Report and Literature Review

The brain regions associated with binge-eating disorder (BED) and those targeted by Lisdexamfetamine (LDX) overlap. The present paper reviews the psychobehavioural and neuropharmacological mechanisms at play in BED and compulsive eating behaviours, along with the mechanisms of action LDX is thought to play. We present one case of chronic BED and highlight the EEG scans pre- and post-LDX treatment. The normalization of the patient’s electroencephalogy (EEG) activity associated with BED after LDX supports theorized mechanisms of LDX action, further explaining its efficacy in treatment. A significant decrease in theta band power was observed in the patient after treatment with LDX. Specifically, this decrease was modulated by changes in the F8 electrode corresponding to the orbitofrontal cortex (OFC)—An area associated with deficits in inhibitory function, seen in addictions and BED. A better understanding of the psychobehavioural and neuropharmacological mechanisms involved in BED and LDX treatment has the potential to significantly enhance our knowledge of the underlying pathogenesis, potential prevention, and optimal treatment options for patients.

Prevalence of Disordered Eating among Non-elite Multisport Endurance Athletes

The prevalence of concerns about food and body weight among non-elite multisport endurance athletes is unknown. This study aimed to evaluate the prevalence of symptoms and concerns related to disordered eating and their association with performance among 162 non-elite athletes involved in multisport endurance summer and winter events. Self-reported symptoms and concerns related to disordered eating were assessed using the Eating Attitudes Test-26 （EAT-26） questionnaire. The mean EAT-26 score （~ SEM） was 6.5 ~ 0.5 and only 9 athletes （5.6%） scored 20 arbitrary units or above. In multivariate regression stepwise analyses, the EAT-26 score （~ = 0.145, P = 0.0003） significantly predicted percent ranking. These findings suggest that the prevalence of self-reported symptoms of disordered eating is low among non-elite multisport endurance athletes. However, greater concerns regarding food intake and body weight may be associated with poorer performance even among non-elite athletes with normal BMI values and at the lower end of the EAT-26 score.

Eating Behavior of Students at the Technical University of Moldova during the Isolation Period

Appetizing peculiarities are formed from childhood and can vary throughout life. Although they are conditioned by genetic factors, over time, the internal regulation of eating behaviors is reduced, being influenced by a complex interaction of various external factors. According to the Behavioral Susceptibility (BST) Theory of Obesity, Food Sensitivity in Response to Food Stimuli (such as Food Sight and Smell) and Satiety Responsiveness (i.e. the ability to adjust diet in response to internal feelings of satiety) contribute to individual differences in terms of energy intake and weight status. The present research intended to assess the eating patterns and behavior of Moldovan students, especially those from Technical University of Moldova during the social isolation imposed by the COVID-19 pandemic. The study was conducted, based on the questionnaires (AEBQ—Adult Eating Behavior Questionnaire), on a group of 602 students from Technical University of Moldova. Participation in the survey was entirely voluntary, did not involve any invasive procedure, nor did it induce changes in participants’ food patterns. The obtained results could contribute to the formation of the database for the study of the behavioral phenotype associated with the risk of obesity, but also for the study of eating behavior in crises. The questionnaire was distributed, in the form of a link, on the corporate emails of all TUM students. Respondents completed the questionnaire on the Google platform between 13.10.2021 - 25.11.2021, and the final database has been downloaded as a Microsoft Excel file. It was established a positive correlation between, Emotional Over-Eating and Emotional Under-Eating. Nervousness and anger were the most incriminating emotions of students that would cause both overeating and under eating. The results of the AEBQ questionnaire appear to be largely in line with previous studies, and the collected data present interest, in particular to prevent the risk of obesity.

Characterization of eating quality and starch properties of two Wx alleles japonica rice cultivars under different nitrogen treatments

To understand the effect of nitrogen(N) fertilizer on rice(Oryza sativa L.) eating and cooking quality(ECQ). Here, we investigated the ECQ attributes, physicochemical foundation of ECQ, and amylopectin fine structure of two Waxy(Wx) alleles japonica rice cultivars Nanjing 9108(NJ9108) and Huaidao 5(HD5) under four N rates(0, 150, 300, and 450 kg ha^-1). Sensory and pasting properties of the two cultivars varied depending on N rates. Compared with the control(0 kg ha^-1), the overall eating quality and sensory value were significantly decreased under the N rates of 300 and 450 kg ha^-1. Further, conventional descriptive analysis showed that the stickiness and retrogradation of cooked rice were significantly decreased. These results indicated that application of N fertilizer seems to affect the texture of cooked rice, causing it to be less sticky, lowering its retrogradation, and consequently reducing its palatability. Results from rapid visco analyzer(RVA) revealed that the peak and breakdown viscosities significantly decreased, while the setback viscosity and peak time increased under the N rates of 300 and 450 kg ha^-1. However, no significant difference was observed when the N rate was 150 kg ha^-1, indicating that less N fertilization can maintain rice ECQ. As the N rate increasing, protein content increased, whereas apparent amylose content, starch content, and gel consistency almost unchanged. Interestingly, compared with the control, under N treatments, the percentage of short amylopectin branches in NJ9108 was decreased, but increased in HD5, as controlled by amylopectin synthesis-related genes. Notably, SSI and BEIIb were down-regulated in NJ9108, whereas BEIIb was up-regulated in HD5. Thus, the palatability of both rice cultivars was significantly decreased under excessive N fertilization as a consequence of reduced stickiness and retrogradation of the cooked rice, which might have resulted from an elevated protein content and altered amylopectin fine structure. In addition, amylopectin synthesis appeared to be affected by N fertilizer and the genotype of the rice cultivar.

Effects of Chalkiness on Cooking,Eating and Nutritional Qualities of Rice in Two indica Varieties

An experiment was conducted to investigate the effects of chalkiness on cooking, eating and nutrition qualities of rice using Gangyou 527 （indica hybrid rice） and Zhaiyeqing 8 （conventional indica rice） as materials. Compared with the milled rice without chalkiness, amylose content, final viscosity, setback and consistence increased significantly, while gel consistence, peak viscosity and breakdown decreased remarkably and other RVA values did not have significant changes in the chalky rice of Gangyou 527. The differences in the above indices between the chalky and non-chalky rice was not remarkable in Zhaiyeqing 8. The crude protein content of chalky rice in Zhaiyeqing 8 was significantly lower than that of non-chalky rice, but there was no remarkable change between the chalky and non-chalky rice in Gangyou 527. Glutelin content fell significantly, and albumin, globulin, prolamine and lysine contents did not change significantly in chalky rice compared with non-chalky rice in the two varieties.

Correlation Between Physicochemical Properties and Eating Qualities of Rice

Correlation among physicochemical properties, which include amylose content, alkali spreading values, gel consistency, water absorption, expansion rate, solid content of rice-water, protein content and fat content, and eating qualities of six kinds of rice samples planted in Heilongjiang Province were studied. Correlation analysis showed that amylose content, water absorption and expansion rate were negatively correlated with eating qualities, yet gel consistency, alkali spreading values, solid content of rice-water and fat content were positively correlated with eating qualities. Among them, eating quality had an obvious correlation with amylose content and gel consistency, but no significant correlation with protein content. The regression equation, which described the relationship of the eating quality scores and physicochemical indexes, was Y=94.439–12.711X1–23.721X2–0.701X3＋0.570X4＋186.938X5（X1, X2, X3, X4 and X5 represented amylose content, water absorption, expansion rate gel, consistency and fat content）. The single factor analysis of variance showed that six kinds of rice existed significant differences in quality category.

Genetic Improvement of Japonica Rice Variety Wuyujing 3 for Stripe Disease Resistance and Eating Quality by Pyramiding Stv-b^i and Wx-mq

Japonica rice variety Kanto 194 as the donor of resistance gene Stv-b^i and Iow-amylose content gene Wx-mq was used to improve the resistance and eating quality of Wuyujing 3 by the breeding strategy of backcross. In continuous backcross and selfcross generations, the related molecular markers with Stvobi and Wx-mq genes were utilized for genotypic detection by associated with resistance identification of rice stripe disease and agronomic traits selection. Finally, 10 improved lines with homozygous genotype Stv-b^i Stv-b^iWx-mqWx-mq were obtained from BC3F4 generation. The results of comparative analysis indicated that most characters of these lines were consistent with those of recipient parent Wuyujing 3, except for the improved resistance, appearance and eating quality. By evaluation of the comprehensive performance of them, two excellent lines K01 and K04 were selected for further experiments.

Functional gastrointestinal disorders in eating disorder patients:Altered distribution and predictors using ROME Ⅲ compared to ROME Ⅱ criteria

AIM:To compare the prevalence of Functional gastrointestinal disorders(FGIDs)using ROMEⅢand ROMEⅡand to describe predictors of FGIDs among eating disorder(ED)patients.METHODS:Two similar cohorts of female ED inpatients,aged 17-50 years,with no organic gastrointestinal or systemic disorders,completed either the ROMEⅢ(n=100)or the ROMEⅡ(n=160)questionnaire on admission for ED treatment.The two ROME cohorts were compared on continuous demographic variables(e.g.,age,BMI)using Student’s t-tests,and on categorical variables(e.g.,ED diagnosis)usingχ2-tests.The relationship between ED diagnostic subtypes and FGID categories was explored usingχ2-tests.Age,BMI,and psychological and behavioural predictors of the common(prevalence greater than 20%)ROMEⅢFGIDs were tested using logistic regression analyses.RESULTS:The criteria for at least one FGID were fulfilled by 83%of the ROMEⅢcohort,and 94%of the ROMEⅡcohort.There were no significant differences in age,BMI,lowest ever BMI,ED diagnostic subtypes or ED-related quality of life(QOL)scores between ROMEⅡand ROMEⅢcohorts.The most prevalent FGIDs using ROMEⅢwere postprandial distress syndrome(PDS)(45%)and irritable bowel syndrome(IBS)(41%),followed by unspecified functional bowel disorders(U-FBD)(24%),and functional heartburn(FH)(22%).There was a 29%or 46%increase(depending on presence or absence of cyclic vomiting)in functional gastroduodenal disorders because of the introduction of PDS in ROMEⅢcompared to ROMEⅡ.There was a 35%decrease in functional bowel disorders(FBD)in RomeⅢ(excluding U-FBD)compared to ROMEⅡ.The most significant predictor of PDS was starvation(P=0.008).The predictor of FH(P=0.021)and U-FBD(P=0.007)was somatisation,and of IBS laxative use(P=0.025).Age and BMI were not significant predictors.The addition of the 6-mo duration of symptoms requirement for a diagnosis in ROMEⅢadded precision to many FGIDs.CONCLUSION:ROMEⅢconfers higher precision in diagnosing FGIDs but self-induced vomiting should be excluded from the diagnosis of cyclic vomiting.Psychological factors appear to be more influential in ROMEⅡthan ROMEⅢ.
