The moderating role of recreational substance use in the association of Mediterranean diet with academic performance among adolescents

No study has examined the potential moderating role of recreational substance use in the relationship between the Mediterranean diet (MedDiet) and academic performance. The aim of this study was to test the potential moderating role of recreational substance use (i.e., alcohol, tobacco, and cannabis) in the association of adherence to the MedDiet with academic performance among adolescents. This cross-sectional study included a sample of 757 adolescents (55.6% girls) aged 12–17 years from the Valle de Ricote (Region of Murcia). The Region of Murcia is an autonomous community of Spain located in the southeast of the Iberian Peninsula, along the coast of the Mediterranean Sea. Adherence to the MedDiet was assessed by the Mediterranean Diet Quality Index for Children and Teenagers (KIDMED). Recreational substance use (i.e., tobacco, alcohol, cannabis) was self-reported by adolescents. Academic performance was assessed by the school records at the end of the academic year. The relationship between adherence to the MedDiet and academic performance was moderated by both tobacco and alcohol use (for grade point average and all school records). In conclusion, higher adherence to the MedDiet was related to greater academic performance in adolescents, but recreational substance use could moderate this association.

Aim: The COVID -19 pandemic has changed the way people live, and children are particularly at risk because of their vulnerable age. The aim of this work was to evaluate the changes in nutritional status, physical activity, and eating habits of elementary school- aged children during the Covid 19 pandemic. Methods: The study was conducted from February to April 2021 and included 197 primary school children, 100 boys, and 97 girls. A questionnaire was used to collect data on lifestyle, eating habits, and physical activity outside school. The Mediterranean Diet Qual- ity Index for children and adolescents was used to determine membership in the Mediterranean diet. The kinanthropological and anthropological data of the students were obtained from the diary of the physical education and health teacher. Results: The average rating of the quality of the children’s diet, as determined by the Mediterranean Diet Quality Index for Children and Adolescents, showed a moderate affiliation with the Mediterranean diet. Before online instruction, 65.9% of students ate break- fast daily, whereas during online instruction, 75.7% ate breakfast (p< 0.001). Results showed that students exercised statistically sig- nificantly more before online instruction than during online instruction (p< 0.05). Students had weaker kinanthropological scores than before beginning online instruction. Conclusions: According to the results, students’ diet is of average quality, and some habits, such as breakfast, have improved, while physical activities have decreased significantly during the pandemic. Therefore, the promotion of proper nutrition and physical ac- tivity through public health programs should be emphasized to educate both children and parents about the importance of proper nutrition, physical activity, and responsible use of various media.

Systemic and Oral Health Parameters in Eutrophic and Overweight/Obese Adolescents: A Cross-Sectional Study.

To date, studies focusing on oral health in obese adolescents have provided controversial data. The aim of this cross-sectional study was to investigate systemic and oral health parameters in eutrophic and overweight/obese adolescents. In total, 100 adolescents, mean aged 13.33 ± 2.04 years, were divided into two groups: 59 overweight/obese adolescents in the study group (SG) and 41 eutrophic-weight adolescents in the control group (CG). Chi-squared and Fisher exact tests were performed to compare dichotomous and categorical variables between the two groups. The subjects in the SG (mean aged 13.21 ± 2.21) reported a body mass index (BMI) of 29.05 ± 4.09 kg/m2, corresponding to over 95° percentile for both genders, and the subjects in the CG (mean aged 13.49 ± 1.77) reported a BMI of 18.26 ± 4.81 kg/m2, corresponding to 25° percentile for both genders. In the SG, the serum level of 25-hydroxy-vitamin D was significantly lower (p-value < 0.001), whereas fasting blood glucose (p = 0.006), waist circumference, and hip circumference were significantly higher (p-value < 0.001). Plaque Index (PI), Plaque Control Record (PCR), Oral Hygiene Index (OHI), Gingival Index (GI), and Gingival bleeding index (GBI) depicted a significantly worse level of oral health in the SG. Moreover, the number of subjects with caries was significantly higher in the SG. Nutritional and physical activity status according to the Mediterranean Diet Quality Index for children and teenagers (KIDMED test) and the International Physical Activity Questionnaire (IPAQ-Adolescent) were reported to be significanlty better in the CG. In light of our results, obesity and poor oral health coexist in a cohort of adolescents. A screening of oral health status should be considered in obese subjects to focus resources on therapeutic interventions aiming at improving oral health.

Diet Quality Index and Food Choice Motives in Vietnam: The Roles of Sensory Appeal, Mood, Convenience, and Familiarity.

Food choices that shape human diets and health are influenced by various socio-economic factors. Vietnam struggles to meet many nutrition targets where links between food choice and diet have not been widely explored. This study assesses the food choice motives, based on a 28-item food choice questionnaire (FCQ), and the diet quality of 603 adults in three sites (urban, peri-urban, and rural) in northern Vietnam. We assess diet quality using the Diet Quality Index-Vietnam (DQI-V) which consists of variety, adequacy, moderation, and balance components. Using factor analysis, we grouped FCQ items into five factors: health focus, sensory appeal, mood ethics, convenience, and familiarity. The structural equation modeling indicates that food choice motives significantly impact the DQI-V and its components but in different directions. The results show that sensory appeal has a positive association with the overall DQI-V score, while having a negative impact on the variety component. Findings present a potential trade-off issue for interventions and policies related to food products. Nutrition knowledge is positively associated with all elements of diet quality across all three study sites. Vietnamese agrobiodiversity could be better utilized to increase dietary diversity. Differentiated policies are necessary to address the poor dietary diversity and adequacy in northern Vietnam.

Mediterranean Dietary Pattern and Psychosocial Health Problems in Spanish Adolescents: The EHDLA Study.

The aims of the present study were twofold: to determine the association between adherence to the Mediterranean diet (MedDiet) and psychological problems and to assess the relationship between different food groups of the MedDiet and different patterns of psychosocial health problems in a sample of Spanish adolescents from the Valle de Ricote (Region of Murcia, Spain). This cross-sectional study included a representative sample of 700 adolescents (57% girls) between 12 and 17 years of age. Adherence to the MedDiet was assessed by the Mediterranean Diet Quality Index for Children and Teenagers (KIDMED). Psychosocial health problems were measured by the 25-item self-report version of the Strengths and Difficulties Questionnaire (SDQ). ANCOVA models were used to test the mean differences in psychosocial health problems (SDQ subscales) by adherence to MedDiet categories (low, medium, and high). Multiple linear regression was used to determine the association between different food groups of the MedDiet and psychosocial health problems. Adolescents with low adherence to the MedDiet had significantly higher scores in SDQ total difficulties, conduct problems, and hyperactivity problems and lower scores in pro-social behavior (p < 0.05) than their peers with medium and high adherence to the MedDiet. In relation to specific MedDiet food groups, fruit, nut, and legume intake were associated with higher psychosocial health. However, sweets, skipping breakfast, or high consumption of pasta or rice (≥5 weeks) were associated to higher psychosocial health problems. Our results show that adolescents with higher adherence to the MedDiet could benefit from greater psychosocial health. Individually, some patterns of MedDiet, such as fruit, nut, and legume intake, may reduce psychosocial health problems. These cross-sectional results should be confirmed in longitudinal and intervention studies.

Mediterranean Diet Quality Index (MDQI) of the pregnant women

Introduction: This study aimed to determine pregnant women's nutritional status and habits in the middle and low-income groups and the level of compliance with the Mediterranean diet. The Mediterranean diet supports healthy fetal growth and development by providing sufficient nutrients for pregnant women and protecting against the development of obstetrical pathologies. Materials and Methods: One hundred and thirty-two pregnant women aged 17-45 were included. The demographic characteristics and anthropometric measurements, systolic blood pressure, fasting, and postprandial blood glucose values were noted.24-hour recall was determined and The Mediterranean Diet Quality Index (MDQI) developed by Gerber et al. was used to assess nutritional status. Nutritional habits and food attitude changes during gestation were recorded. Results: Overall, 15.2% of the pregnant women had good, 54.5% had medium-good, and %29.5 had medium-poor adherence to MDQI. The dietary macronutrient intakes were close to the daily dietary recommended intakes (DRI); however, micronutrient intakes were below the recommendations. Pre-pregnancy mean BMI was found to be 26.4 kg/m2. Conclusions: According to the mean pre-pregnant BMI, the pregnant women were overweight, and their adherence to the Mediterranean diet needed to be improved. General measures should be taken to improve pregnant women's diets and micronutrient intakes, even in the Mediterranean countries where this diet is the daily nutrition habit of local inhabitant pregnant women.

Poor Quality Diets Characterized by Low-Nutrient Density Foods Observed in One-Quarter of 2-Year-Olds in a High Resource Setting

BackgroundYoung children have high nutritional requirements relative to their body size, making healthy diets critical for normal growth and development. ObjectiveWe aimed to integrate analysis of dietary patterns among 2-y-old children with indicators of dietary quality, micronutrient status, and body weight status. MethodsData from the 2-y follow-up of the Cork BASELINE Birth Cohort included dietary assessment using a 2-d weighed food diary, vitamin D and iron status biomarkers, and anthropometry (n = 468). K-means cluster analysis identified predominant dietary patterns based on energy contributions and associations with nutrient intakes and status and body weight were investigated. ResultsFour dietary patterns emerged: “Cows’ milk” (unmodified cows’ milk: 32% of total energy (TE)); “Traditional” (wholemeal breads, butter, fresh meat, fruit); “Low Nutrient Density (LND) foods” (confectionary, processed meat, convenience foods) and “Formula” (young child formula: 23%TE). The LND pattern was associated with excessive free sugar intake (14%TE) and salt intake (153% of daily limit). No differences in patterns of overweight were observed between the 4 groups; however, the LND group had 3-fold higher odds of being underweight [aOR (95% CI): 3.2 (1.2, 8.5)]. Children consuming >400ml/d of cows' milk or formula exhibited lower dietary variety, fewer family-type meals, and continued use of feeding bottles (75% and 81%, respectively, vs. 35-37% in the other groups). ConclusionsUnhealthy eating habits are common among young children. Dietary guidance to support families to provide healthy diets needs to maintain currency with eating habits and focus on food choices for meals, snacks, and beverages.

Greenhouse Gas Emission and Water Footprint of the National Diet in Turkey: Results from Turkey Nutrition and Health Survey 2017

The study aimed to assess and characterize the sustainability of the national diet in Turkey and its association with diet quality, dietary requirements, and sociodemographic factors. Dietary intake was assessed using 24 h recalls from the Turkey Nutrition and Health Survey 2017 (TNHS-2017) (n = 12,527). The environmental footprints were assessed with two environmental indicators: greenhouse gas emissions (GHGEs) and water footprint (WF). Diet quality was assessed using the diet quality index (DQI) and dietary diversity score (DDS). The dietary GHGEs was 3.21 ± 2.07 kg CO2-eq/person/day and the dietary total WF was 2832 ± 1378 L/person/day. The DQI and DDS were 62.26 ± 8.28 and 6.66 ± 1.31, respectively. Total energy intake was significantly higher in the highest GHGEs and total WF tertiles (2238 ± 722 and 2383 ± 701 kcal, respectively) compared to lower GHGEs and total WF tertiles. Individuals with higher diet-related GHGEs and total WF had a higher daily intake of nutrients with the exception of the percentages of energy supplied from carbohydrates, percentages of meeting nutrients according to the recommended dietary allowance (RDA), DQI (excluding DQI total, moderation, and overall balance score), and DDS scores (p &lt; 0.001). GHGEs and total WF value of the national diet in Turkey are lower than the world average. The results would help develop dietary guidelines to encourage sustainable dietary choices.

Socioeconomic status, lifestyle characteristics and adherence to the Mediterranean diet among Greece adolescents

ObjectiveThe study aims to assess the relationship between socioeconomic status, lifestyle characteristics and adherence to the Mediterranean diet within a representative sample of secondary school children from Attica, Greece. Research methods & proceduresIn this cross-sectional school-based study, 2088 adolescents aged 12–18 from different socioeconomic status areas of Attica in Greece have been recruited. The study occurred in May-December 2021 when schools reopened due to COVID-19 closure. Socioeconomic status was determined using Family Affluence Scale (FAS) III questionnaire. The Mediterranean Diet Quality Index for children and adolescents (KIDMED test) was used to assess the adherence to the Mediterranean diet. The empirical investigation was based on bivariate analysis following chi-square tests and multivariate approaches employing Generalized Ridge Regression models and Blinder-Oaxaca decomposition techniques. ResultsA very low percentage of 9.1% of the adolescents had optimal adherence to the Mediterranean diet, while 57.9% and 33% had moderate and low adherence, respectively. Boys, younger adolescents, adolescents from two parents' families, with higher maternal education and socioeconomic status had higher adherence to the Mediterranean diet. Additionally, healthier lifestyle with more studying, efficient night sleep, frequent physical activity, going out, and having hobbies were positively associated with adherence to the Mediterranean diet. On the contrary, more screen viewing was related negatively. ConclusionsSeveral demographic, lifestyle, and socioeconomic characteristics significantly affect adherence to the Mediterranean diet. In particular, findings showed that higher socioeconomic status and a healthier lifestyle are associated with optimal adherence. Greek adolescents move away from the traditional Mediterranean Diet.

Nutrition knowledge, diet quality and orthorexic behaviors in Polish students-a pre-post repeated cross-sectional study.

Nutrition knowledge acquired in college students may not only help in promoting an adequate diet, but also lead to excessive preoccupation with healthy eating, which is referred to as orthorexic behaviors. This study aimed to assess the relationship between nutrition knowledge, diet quality and orthorexic behaviors among college students of food and nutrition majors. Data were collected from a sample of 131 college students through a pre-post repeated cross-sectional study conducted from 2018 to 2021. The participants were asked to complete the ORTO-6 questionnaire, the nutrition knowledge test "GAROTA", and the Beliefs and Eating Habits Questionnaire (KomPAN). The results indicated that students' preoccupation with healthy eating (orthorexic behaviors score) during the study period did not change, in contrast nutrition knowledge and diet quality increased. There was no correlation between the orthorexic behaviors score and the nutrition knowledge score, both at the beginning and end of the study. At the beginning of the study, the orthorexic behaviors score correlated positively with "Pro-Healthy Diet Index" and "Diet-Quality Index", and inversely with "Non-Healthy Diet Index". However, at the end of the study, no significant correlations were observed between these variables. It can be concluded that nutrition knowledge determined positively the quality of the diet of students in food and nutrition majors, while did not affect the occurrence of orthorexic behaviors.

Dietary Quality and Circulating Lipidomic Profiles in 2 Cohorts of Middle-Aged and Older Male Finnish Smokers and American Populations

BackgroundHigher dietary quality is associated with lower disease risks and has not been examined extensively with lipidomic profiles. ObjectivesOur goal was to examine associations of the Healthy Eating Index (HEI)-2015, Alternate HEI-2010 (AHEI-2010), and alternate Mediterranean Diet Index (aMED) diet quality indices with serum lipidomic profiles. MethodsWe conducted a cross-sectional analysis of HEI-2015, AHEI-2010, and aMED with lipidomic profiles from 2 nested case-control studies within the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial (n = 627) and the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study (n = 711). We used multivariable linear regression to determine associations of the indices, derived from baseline food-frequency questionnaires (Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial: 1993–2001, Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study: 1985–1988) with serum concentrations of 904 lipid species and 252 fatty acids (FAs) across 15 lipid classes and 28 total FAs, within each cohort and meta-analyzed results using fixed-effect models for lipids significant at Bonferroni-corrected threshold in common in both cohorts. ResultsAdherence to HEI-2015, AHEI-2010, or aMED was associated positively with 31, 41, and 54 lipid species and 8, 6, and 10 class-specific FAs and inversely with 2, 8, and 34 lipid species and 1, 3, and 5 class-specific FAs, respectively. Twenty-five lipid species and 5 class-specific FAs were common to all indices, predominantly triacylglycerols, FA22:6 [docosahexaenoic acid (DHA)]-containing species, and DHA. All indices were positively associated with total FA22:6. AHEI-2010 and aMED were inversely associated with total FA18:1 (oleic acid) and total FA17:0 (margaric acid), respectively. The identified lipids were most associated with components of seafood and plant proteins and unsaturated:saturated fat ratio in HEI-2015; eicosapentaenoic acid plus DHA in AHEI-2010; and fish and monounsaturated:saturated fat ratio in aMED. ConclusionsAdherence to HEI-2015, AHEI-2010, and aMED is associated with serum lipidomic profiles, mostly triacylglycerols or FA22:6-containing species, which are related to seafood and plant proteins, eicosapentaenoic acid-DHA, fish, or fat ratio index components.

Adherence to diet with higher dietary diabetes risk reduction score is associated with reduced risk of type 2 diabetes incident in Iranian adults

BackgroundThe Dietary diabetes risk reduction score (DDRRS) has recently been considered by researchers as a diet quality index to predict the risk of chronic diseases, such as type 2 diabetes (T2D). In this study, we aimed to assess the association of DDRRS with T2D risk in Iranian adults.MethodsSubjects aged ≥ 40 years without T2D (n = 2081) were selected for the current study from participants of the Tehran Lipid and Glucose Study (2009–2011) and followed for a mean of 6.01 years. We used the food frequency questionnaire to determine the DDRRS that is characterized by eight components, including higher consumption of nuts, cereal fiber, coffee, and polyunsaturated to saturated fat ratio and lower consumption of red or processed meats, trans fats, sugar-sweetened beverages, and high glycemic index foods. The multivariable logistic regression analysis was used to determine the odds ratio (ORs) and 95% confidence interval (CI) of T2D across the DDRRS tertiles.ResultsThe mean ± SD age of individuals was 50.4 ± 8.2 years at baseline. The Median (25–75 interquartile range) DDRRS of the study population was 24(22–27). During the study follow-up, 233(11.2%) new cases of T2D were ascertained. In the age and sex-adjusted model, the odds of T2D were decreased across tertiles of DDRRS (OR = 0.68; 95%CI: 0.48–0.97, P for trend = 0.037). Based on the multivariable-adjusted model, after controlling all potential confounders, the risk of T2D is reduced across tertiles of DDRRS (OR = 0.66; 95%CI: 0.44–0.98, P for trend = 0.047). Also, higher scores (lower consumption) of red and processed meat (OR = 0.59; 95%CI: 0.39–0.88, P = 0.012) and sugar-sweetened beverages (OR = 0.49; 95%CI: 0.32–0.76, P = 0.002) as DDRRS components were associated with decreased T2D incident.ConclusionsOur findings suggested that a diet with a higher score of DDRRS may be related to reducing the risk of T2D in Iranian adults.

Is Adherence to the Mediterranean Diet Associated with Eating Behaviour and Emotional Appetite in Young Women?

Introduction: This study aimed to evaluate the effects of adherence to the Mediterranean Diet (MD) on eating attitudes and emotional appetite in young females aged 18-24. Methodology: A cross-sectional study (n=306) was conducted on young females. A questionnaire including demographic characteristics, Eating Attitudes Test-26 (EAT-26), Emotional Eating Questionnaire (EMAQ), and International Physical Activity Questionnaire (IPAQ) was applied. Daily food consumption was obtained from the 24-hour- food records and used to calculate the Mediterranean Diet Quality Index (MAI). The researchers measured the body weight (kg) and height (cm). Results: Half of the participants (50.7%) have low adherence to the MD, moderate in 25.2%, and high in 24.2%. There is no statistical difference in MAI scores between EAT-26 groups (p&gt;0.05). The dieting status was higher (28.2%) in the disordered eating tendencies group compared to the group without disordered eating tendencies (11.1%) (χ2 =12.490, p&lt;0.001). The scores of the negative total scores were higher in the group with disordered eating risk (p=0.004). Conclusions: Young females’ low adherence to Mediterranean Diet might be associated with future health problems. No effect of MAI on disordered eating behavior was determined but EMAQ-negative sub and total scores were determined as a component of EAT-26. Early detection of diet quality and conditions associated with emotional eating disorders is thought to be important in preventing future health problems.

Diets of Men and Women in Rural Bangladesh Are Equitable but Suboptimal

BackgroundRecent evidence suggests that diet inequities between men and women may have diminished within rural Bangladeshi households. However, this has not been directly tested with appropriate physiologic adjustments and it is unclear whether changes have occurred across socioeconomic strata. Understanding intrahousehold dietary patterns at different points on the income and food-security distribution in rural Bangladesh—particularly, within ultrapoor and farm households—is important for appropriate design of gender-sensitive and nutrition-sensitive interventions, which often target these groups. ObjectiveUsing 2012 and 2016 data, we aimed to examine gender differences in diet quantity and quality among ultrapoor and farm households in rural Bangladesh. MethodsThe study used baseline 24-h dietary data from 2 randomized control trials conducted in rural Bangladesh: the Transfer Modality Research Initiative (ultrapoor households) and the Agriculture, Nutrition, and Gender Linkages project (farm households). Ordinary least squares regressions with household-level fixed effects tested for gender differences among constructed diet measures, such as caloric intake, caloric adequacy ratio, dietary diversity score, global diet quality score, and probability of consuming moderate or high levels of healthy food groups. ResultsIn both samples, on average, women consumed fewer calories than men in the same households but consumed near equal or more in reference to their caloric needs. Women scored <1% lower than men on diet quality indicators and showed similar probabilities to men of consuming healthy foods. Most men and women in both samples were calorically inadequate (>60%) and recorded poor diet quality scores that indicated high risk of nutrient inadequacy and chronic disease (>95%). ConclusionsIn both ultrapoor and farm households, although men record higher intake quantities and diet quality scores, the apparent male advantage disappear when energy requirements and the magnitudes of difference are considered. Diets of men and women in these rural Bangladeshi households are equitable but suboptimal.

Effects of dietary sugar restriction on hepatic fat in youth with obesity.

Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease in children. Like adults, children can develop the progressive form of NAFLD, nonalcoholic steatohepatitis (NASH), which is characterized by hepatic inflammation, often in the presence of fibrosis. Children with NAFLD are at higher risk of liver-related complications, metabolic dysfunction, and cardiovascular disease in adulthood. Many factors contribute to the escalating prevalence of NAFLD in the pediatric population, among which are an array of dietary patterns such as overnutrition, poor diet quality, and heavy consumption of fat and sugar, including fructose. Findings from an increasing number of epidemiological studies support a connection between high habitual sugar consumption and NAFLD, especially within the context of obesity, but these studies are not able to demonstrate whether sugar is a contributing factor or instead an indicator of an overall poor diet (or lifestyle) quality. To date, only four randomized controlled dietary interventions assessing the effects of sucrose/fructose restriction on hepatic fat fraction in youth with obesity have been published. The objectives of this review are to summarize the key findings from these dietary interventions to achieve a better understanding of the strength of the relationship between dietary sugar restriction and liver fat reduction, despite their inherent limitations, and to discuss the potential impact of weight loss and fat mass reduction on improvement in hepatic steatosis.

0235 Social Jetlag and Diet Quality Among US Young Adults

Abstract Introduction Young adults are among the populations with the lowest quality diets in the US, and poor sleep could be a contributing factor. Social jetlag, the lack of consistent sleep timing from weekdays to weekends, is also more common among young adults. Our objective was to examine associations between social jetlag and diet quality among US young adults, and to evaluate effect modification by sex or race/ethnicity. Methods The study population included 1,308 adults aged 20-39 who participated in the 2017-2018 National Health and Nutrition Examination Survey. Social jetlag was considered as ≥2-hour difference in sleep midpoint (median of bedtime and wake time) between weekends and weekdays. Diet quality was assessed with the Healthy Eating Index (HEI)-2015, which is comprised of 13 dietary components and ranges from 0 to 100 (higher scores=better diet quality). Scores were binned into three groups based on tertile cutoffs. Ordinal logistic regression analyses were utilized to evaluate the relationship between social jetlag and HEI-2015 scores as well as the individual HEI components, adjusting for age, sex, race/ethnicity, educational attainment, recent tobacco use and physical activity. Effect modification by sex and race/ethnicity were also considered. Results In the analytic sample, 31% of young adults had social jetlag. Overall, there were no associations between social jetlag and diet quality. However, interaction analysis revealed several associations were race-specific (P, interaction&amp;lt; 0.05). Among Black adults, social jetlag was associated with lower overall diet quality (OR = 0.4, 95% CI 0.2, 0.8; i.e., less likely to be in higher diet quality tertiles) and more unfavorable scores on total vegetables (OR = 0.6, 95% CI 0.3, 1.0) and added sugar (i.e., OR = 0.6, 95% CI 0.4, 0.9). For Hispanic adults, social jetlag was associated with higher intakes of sodium (OR=0.6, 95% CI 0.4, 0.9) However, White adults with social jetlag had higher intake of greens and beans (OR = 1.9, 95% CI 1.1, 3.2). Conclusion Within a nationally-representative sample of US young adults, social jetlag was related to certain indicators of lower diet quality among Black and Hispanic Americans. Support (if any) Dr. Jansen was supported by K01HL151673.

Prevalence of functional gastrointestinal disorders in Italian children living in different regions: analysis of the difference and the role of diet

BackgroundFunctional Gastrointestinal Disorders (FGIDs) are common in pediatric age. AimsTo estimate the prevalence of FGIDs in Italian children and evaluate the impact of diet. MethodsHealthy children aged 4–18 years were recruited in a multicenter cross-sectional study. We evaluated their eating habits and the presence of FGIDs, using Rome IV criteria, 3-day food diaries and Mediterranean Diet Quality Index (KIDMED) questionnaires. ResultsSeven hundred forty subjects were enrolled:369 children aged 4–9 years (Group A), and 371 adolescents 10–18 years old (Group B). The overall prevalence of FGIDs was 26.4% in Group A and 26.2% in Group B, with a significant higher prevalence in females in both groups. The most frequent disorders were functional constipation, functional dyspepsia, and abdominal migraine. No significant difference in FGIDs prevalence was found between Northern and Southern Italy, despite significant variation in diet. In Group A there was a significant difference in KIDMED between North and South (5.3 ± 1 vs 6 ± 1.2, respectively; p = 0.001). A significant association between FGIDs and KIDMED was found in Group A (OR=0.83, p = 0.034), but not in Group B (OR=0.89, p = 0.166). ConclusionsFGIDs are common in Italian children, with a higher prevalence in females. Despite significant differences in dietary habits between North and South, FGIDs prevalence does not vary significantly.
