Skipping breakfast is associated to inadequate nutrient intakes among Tunisian children: a cross-sectional study.

Breakfast is widely acknowledged as a crucial meal of the day, particularly for children, owing to its role in supplying essential nutrients and energy necessary for optimal growth and cognitive function. This study aims to examine differences in nutrient intake between breakfast skippers and non-skippers among children. A representative sample of 1,200 Tunisian preschool and schoolchildren, aged 3-9 years, was randomly selected from kindergartens and primary schools in the Greater Tunis region which includes four governorates (Tunis, Ariana, Manouba and Ben Arous) using a two-stage cross-sectional design. Stratification was carried out depending on each of the selected governorates and urban/rural areas. Dietary intake was evaluated using the 24-hour recall method and a diet history covering the week preceding the survey. Nutritional food composition was derived from a specific Tunisian food composition database. Nutrient intake below age- and sex-specific reference values was considered inadequate. The findings indicate that the daily intake of energy and nutrients was lower among breakfast skippers compared to regular breakfast eaters. After adjusting for energy, gender, age, BMI and household economic proxy, the daily consumption of total sugar, riboflavin, vitamin B-5, phosphorus and calcium was higher among breakfast consumers while saturated fatty acid intake was higher among skippers. A comparative analysis of daily mean food category intake between the two groups revealed a higher consumption of milk and dairy products among breakfast consumers. Regular breakfast consumption is an important part of maintaining a balanced diet and healthy weight.

Increased self-regulation of eating behavior is associated with reduced generalized anxiety disorder in Saudi Arabia.

There is a growing body of evidence suggesting that self-regulation of eating behavior (SREB) is closely linked to dietary habits and mental health. However, little is known about these relationships within the Saudi Arabian population. This study aimed to address this gap. A digital cross-sectional study was conducted utilizing the SREB and generalized anxiety disorder (GAD-7) questionnaires, along with a brief survey about dietary habits. Linear and logistic regression analyses were employed to examine these associations, with a total of 651 Saudi participants enrolled in the study. The results showed that only 15.5% of participants demonstrated a high capacity for SREB, while 65% experienced moderate or severe symptoms of GAD. Greater SREB was significantly associated with reduced GAD scores (β = -0.13, 95% CI; -0.12 to -0.03; p < 0.001) and lower BMI (β = -0.10, 95% CI; 0.08 to -0.00; p = 0.01). Additionally, predictive factors for high capacity for SREB included higher daily intake of fruits (OR = 2.90, 95% CI; 1.44 to 5.84; p = 0.003) and regular breakfast consumption (OR = 1.64, 95% CI; 1.01 to 2.63; p = 0.04). These findings suggest that enhancing SREB may be a promising strategy for obesity prevention and improving mental health outcomes among the Saudi population. Implementing interventions aimed at promoting healthier dietary habits could support the physical and mental well-being of this population.

Associations of regular consumption of breakfast, lunch and dinner with Body Mass Index during adolescence: longitudinal findings by weight status among the Eating and Activity over Time 2010-2018 cohort.

To examine how the associations between meal consumption and BMI over 8 years differ by weight status in a sample of adolescents. Longitudinal, population-based study. Breakfast, lunch and dinner consumption and BMI were self-reported. Linear regressions were used to examine how the associations between meal consumption and BMI differed by weight status. Adolescents in the Minneapolis/St. Paul metropolitan area. Adolescents (n 1,471) were surveyed as part of the EAT 2010-2018 in 2009-2010 (Mage = 14·3 years) and 2017-2018 (Mage = 22·0 years). The prevalence of regular breakfast, lunch and dinner consumption (≥ 5 times/week) ranged from 45 to 65 %, 75 to 89 % and 76 to 94 %, respectively, depending on weight status category. Among adolescents with a sex- and age-specific BMI < 15th percentile, regular consumptions of breakfast, lunch and dinner during adolescence were positively associated with BMI in emerging adulthood compared with irregular consumption of breakfast, lunch and dinner (<5 times/week) after adjustment for socio-demographic characteristics (β = 5·43, β = 5·39 and β = 6·46, respectively; all P-values <0·01). Among adolescents in the BMI 15-85th and 85-95th percentiles, regular consumptions of breakfast, lunch and dinner were positively associated with BMI but to a lesser extent (P-values <0·01). For participants with a BMI ≥ 95th percentile, regular consumptions of breakfast, lunch and dinner were positively associated with BMI, but the associations were not statistically significant (P-values > 0·05). The relationship between meal consumption during adolescence and BMI in emerging adulthood differs by adolescent weight status. Future studies should investigate underlying factors related to meal consumption routines and BMI.

The mediating role of dietary inflammatory index on the association between eating breakfast and depression: Based on NHANES 2007–2018

BackgroundDepression is a significant, pervasive, global public health problem, associated with many factors, such as diet, social factors, and lifestyle habits. We aimed to evaluate the association between eating breakfast, dietary inflammatory index (DII) and depression, and to verify the mediating role of DII on the effect of eating breakfast on depression. Methods21,865 participants from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2018 were included in this study. Binary logistic regression and mediated effect analysis were conducted to analyze the associations between eating breakfast, DII and depression. Dietary inflammation was divided into pro-inflammatory diet and anti-inflammatory diet according to the DII. ResultsBoth pro-inflammatory diet and skipping breakfast were risk factors for depression. After adjusting for covariables, compared with participants reporting breakfast in both recalls, reporting breakfast in one recall had a higher OR 95%CI (1.54(1.20, 1.98)) of depression. These associations in stratified analysis and sensitivity analysis without cardiovascular diseases (CVD) and diabetes were robust. DII mediated the association between eating breakfast and depression, the proportion of participants who reported breakfast in one recall and no recall was 26.15 % and 26.67 %, respectively. LimitationsThis was a cross-sectional study that couldn't argue for the cause-effect relationship. Moreover, the confounding factor regarding medication use was not accounted for due to limited data. ConclusionsSkipping breakfast may increase the risk of depression by raising DII. And our study supported the essential role of regular breakfast and the anti-inflammatory diet in reducing the risk of depression.

The Relationship between Breakfast and Sleep and Cardiovascular Risk Factors.

Despite extensive research on the individual effects of breakfast and sleep on health outcomes, there has been limited investigation into their combined effects. We aimed to evaluate the relationship between breakfast-eating behavior and sleep timing on cardiovascular disease (CVD) risk factors. A total of 16,121 participants (6744 men and 9377 women) aged 19 years or older were selected from the Korea National Health and Nutrition Examination Surveys (2016-2018, 2021). We classified participants into four groups: early sleep + regular breakfast eaters (group 1), late sleep + regular breakfast eaters (group 2), early sleep + infrequent breakfast eaters (group 3), and late sleep + infrequent breakfast eaters (group 4). In men, group 4 had a lower prevalence of obesity than group 1 (OR 0.78, 95%CI 0.62-0.97), and groups 2, 3, and 4 had a higher prevalence of metabolic syndrome (MetS) than group 1 (OR 1.43, 1.62, and 1.47, respectively). In women, group 4 had a lower prevalence of dyslipidemia than group 1 (OR 0.59, 95%CI 0.44-0.80), and group 2 had a higher prevalence of MetS than group 1 (OR 1.24, 95%CI 1.03-1.50). The combination of skipping breakfast and late sleep timing was associated with the higher prevalence of MetS particularly in men. Moreover, the relationship between breakfast and sleep timing on CVD risk factors differed by sex and age group.

Association between Perceived Psychological Stress and Exercise Behaviors: A Cross-Sectional Study Using the Survey of National Physical Fitness.

Perceived psychological stress and exercise are bidirectionally related, and the effects of exercise on stress relief are well documented. However, research on the influence of stress on exercise remains scarce. This study examined the association between perceived psychological stress and exercise participation among Korean adults and older adults as well as the relationship between exercise frequency and perceived stress. Data on 3440 participants (2813 adults aged 19-64 and 627 older adults aged 65 or more) were collected from the Survey of National Physical Fitness conducted by the Korea Institute of Sport Science and the Korean Ministry of Culture, Sports and Tourism in 2015. We compared the participants' health-related behaviors, including exercise, regular breakfast consumption, and smoking, according to their perceived psychological stress levels. Those who perceived a higher level of psychological stress reported lower levels of exercise participation, regular breakfast consumption, and smoking, with the exception of older male participants. The study also found that a higher frequency of exercise participation corresponded with a lower perceived level of psychological stress (β = -0.080, p < 0.001) and that engaging in physical activity even once a week yields a substantial reduction in stress levels. In a large sample of Koreans, high levels of perceived psychological stress were significantly associated with less physical activity and infrequent weekly exercise. This study found a dose-response relationship between exercise frequency and reduced stress and suggested that psychological stress should be considered crucial in promoting physical activity.

Association between shift work in early pregnancy, snacking, and inappropriate weight gain during pregnancy: The Japan Environment and Children's Study.

This study aimed to investigate the relationship between night shifts and snacking behaviors during pregnancy using Japanese maternal-infant longitudinal data from a large-scale study. This study used the Japan Environment and Children's Study dataset jecs-ta-20190930, released in October 2019. After simple analysis using analysis of variance and multiple comparisons, crude odds ratios (cOR) and adjusted odds ratios (aORs) were calculated. To evaluate eating habits, we examined habitual fast food and snacks (e.g., potato chips, corn puffs and tortilla chips) consumption, midnight snacks, and regular missing breakfast. There was no significant association between inappropriate weight gain during pregnancy and night shift work in early pregnancy. The aOR for consuming snacks more than once a week after noticing pregnancy for shift workers was 1.34 (95% confidence interval 1.27-1.41; p < 0.001) compared with worker without night shiftwork. The aOR for shift workers consuming fast food more than three times a week during pregnancy was 1.40 (95% confidence interval 0.79-2.33; p > 0.05). Pregnant night shift workers did not show excessive weight gain but had an increased frequency of consumption of snack foods compared with pregnant dayshift workers.

Association between regular breakfast consumption and academic performance among 6th-grade elementary school male students in Makkah, Saudi Arabia

Objectives: To determine the association between regular breakfast consumption and academic performance among 6th-grade elementary school male students in Makkah, Saudi Arabia.&#x0D; Methods: Our cross-sectional study used a questionnaire for public and private elementary school children in Makkah, Saudi Arabia. Participants with known mental retardation, language barriers, and chronic diseases were excluded. The data analysis was performed using IBM SPSS V.26.&#x0D; Results: In our study, 412 students were included. Most students (74.3%) obtained a high final degree between 80 - 100%. Most students (67.2%) believed having breakfast helps in obtaining high degrees. In addition, those who never had breakfast had a lower academic degree (p-value &lt;0.001).&#x0D; Conclusion: The results of our study emphasized the significance of having breakfast on a daily basis for academic success, as students who reported consuming breakfast regularly were found to be more likely to achieve high academic scores.

Eating Behavior and Factors of Metabolic Health in Primary Schoolchildren: A Cross-Sectional Study in Greek Children.

Childhood obesity has been associated with altered blood lipids and bad eating habits. In this cross-sectional study, we assessed cardiorespiratory fitness and metabolic health markers in regard to weight status and dietary habits in schoolchildren. In 134 children (6-11 years), we conducted: (1) Anthropometry, namely z-score BMI (z-BMI), waist-to-height ratio (WHtR), and body composition analysis. (2) Measurements of handgrip strength (HGS), resting metabolic rate (RMR) and VO2max. (3) Quantification of blood lipids and antioxidant vitamins A, E, C. (4) Eating breakfast assessment. About 35% of children were overweight/obese. The z-BMI positively correlated with WHtR (r = 0.637, p < 0.001), and adversely correlated with fat-free mass (r = -0.728, p < 0.001) and vitamin E (r = -0.286, p < 0.001). RMR and VO2max were greater in normal weight children compared to those with overweight/obesity (p < 0.001). HGS did not differ between these groups, but was negatively correlated with dyslipidemia as shown by TG/HDL-C ratio (r = -0.224, p = 0.037). According to regression analysis, eating breakfast routinely at home was positively associated with RMR and adversely associated with z-BMI. Hence, regular breakfast consumption at home may improve RMR in kids. Cardiorespiratory fitness and physical strength are key modulators of metabolic health in Greek children added to a social determinant of health i.e., eating breakfast at home.

Household socio-economic determinants of food security in Limpopo Province of South Africa: a cross sectional survey

BackgroundDespite the strong commitment at both national and international levels to eradicate hunger and achieve household food security, by 2030 food insecurity remains a public health problem. South Africa is amongst the countries with the highest rate of income inequality in the world and extremely high levels of absolute poverty. The Gini coefficient in South Africa is estimated at 0.68 Although South Africa may be food secure at a national level, large numbers of households within the country are food insecure approximately 52% of the rural households in Limpopo Province of South Africa were considered severely food insecure. It has been noted that the majority of households in South African informal settlements and rural areas were moderately or severely food insecure due to lack of access to food which was directly related to income. Rural areas have assets that can be explored to support households. The adult population above 18 years in South Africa make up 78% of the 5.9 million population with about 40% living in rural areas, this study explored household food insecurity in adults in rural environments. The current study aimed to explore the socioeconomic and dietary determinants of household food insecurity among the adult population in the Limpopo Province.MethodsA cross-sectional survey design was used, and data were collected using a validated pre-tested questionnaire. The participants were recruited from households in Limpopo province. Multiple linear regression was computed to explore the influence of socioeconomic and dietary practices on food insecurity.ResultsThe study included 699 randomly selected participants of which the majority earned a monthly income ≤ 3000 ZAR, and 31.8% experiencing hunger in the past 30 days at the time of study. The dietary practices of the participants were found to be associated with household food insecurity. The study found that large family size, being female in South Africa, low household income and low rate of regular breakfast intake were significant determinants of household food insecurity (p < 0.05).ConclusionIn summary, most of the households were poor and approximately one-third were food insecure. The implementation of sustainable employment policies, and food-based approaches and targeting rural household food production could significantly reduce food insecurity in the rural area.

Breakfast Frequency and Sleep Quality in College Students: The Multiple Mediating Effects of Sleep Chronotypes and Depressive Symptoms.

Sleep disorders, which are prominent problems among college students, may be associated with skipping breakfast. Therefore, we aimed to explore the role of sleep chronotypes and depressive symptoms as mediators in the relationship between breakfast frequency and sleep quality. A cross-sectional survey enrolling random samples of 712 college students was conducted by the Questionnaire Star online platform. Statistical description and correlation analysis were performed by SPSS 25.0, and a chain mediation test was performed by model 6 in PROCESS 3.5. The result of the article demonstrated that breakfast frequency can affect sleep quality through two mediating pathways: ① sleep chronotypes, with a mediating effect of 32%; and ② depressive symptoms, with a mediating effect of 52.4%. However, the chain mediating effects of sleep chronotypes and depressive symptoms was not significant, and neither was the direct effect of breakfast frequency on sleep quality. Breakfast frequency can indirectly affect sleep quality by adjusting sleep chronotypes and depressive symptoms. Regular breakfast can increase morning and intermediate sleep chronotypes, reduce depressive symptoms, and thus improve sleep quality.

Longitudinal Changes in Body Composition and Resting Metabolic Rate in Male Professional Flat Jockeys: Preliminary Outcomes and Implications for Future Research Directions

Jockeys are unique given that they make weight daily and, therefore, often resort to fasting and dehydration. Through increasing daily food frequency (during energy deficit), we have reported short-term improvements in jockey's body composition. While these changes were observed over 6-12weeks with food provided, it is unclear whether such improvements can be maintained over an extended period during free-living conditions. We, therefore, assessed jockeys over 5years using dual X-ray absorptiometry, resting metabolic rate, and hydration measurements. Following dietary and exercise advice, jockeys reduced fat mass from baseline of 7.1 ± 1.4kg to 6.1 ± 0.7kg and 6.1 ± 0.6kg (p < .001) at Years 1 and 5, respectively. In addition, fat-free mass was maintained with resting metabolic rate increasing significantly from 1,500 ± 51kcal/day at baseline to 1,612 ± 95kcal/day and 1,620 ± 92kcal/day (p < .001) at Years 1 and 5, respectively. Urine osmolality reduced from 816 ± 236mOsmol/L at baseline to 564 ± 175mOsmol/L and 524 ± 156mOsmol/L (p < .001) at Years 1 and 5, respectively. The percent of jockeys consuming a regular breakfast significantly increased from 48% at baseline to 83% (p = .009) and 87% (p = .003) at Years 1 and 5, alongside regular lunch from 35% to 92% (p < .001) and 96% (p < .001) from baseline to Years 1 and 5, respectively. In conclusion, we report that improved body composition can be maintained in free-living jockeys over a 5-year period when appropriate guidance has been provided.

Factors Associated with Breakfast Skipping among Undergraduate Medical Students of a Selected Medical College in Bangladesh

Background: Breakfast is a commonly skipped meal especially for young adult during their university study period. Objective: This study aimed to determine the factors related to skipping breakfast among medical students in this study. Methods: This cross-sectional study was conducted among the 4th year medical students of Sher-e-Bangla Medical College, Barishal in January 2022 using a self-administered questionnaire recording the demography, breakfast consumption habits, and other factors like physical condition, appetite, sleep quality, social relation with others and learning. Results: A good proportion of the students (63.3%, 95% CI: 56.18-70.38%) skip breakfast. Waking up late (OR-11), sleeping late (OR-7), and staying in hostels (OR- 8) were the important factors significantly associated (p&lt;0.05) with breakfast skipping. Conclusions: Breakfast skipping behavior is high among undergraduate medical students. The students should be encouraged to eat regular breakfast through health promotion campaigns.

Socioeconomic Disparities in Adolescents' Caries Prevalence

Introduction: Policymakers and academics have explored the behavioral approach in their attempts to explain and address the socioeconomic disparities in adolescents' oral health. However, evidence regarding this issue is scarce in the Korean adolescent population. This study aimed to examine whether socioeconomic status is associated with dental caries and whether oral health-related behaviors (OHRBs) explain or moderate the hypothesized association in Korean adolescents. Methods: A secondary analysis was conducted using the Korea National Health and Nutrition Examination Survey data from 2016 to 2019. Adolescents (n = 1062) aged 13–18 years were included in the analysis. The association between income and untreated decayed permanent teeth (DT) was investigated, focusing on the intermediary roles of OHRBs, using hierarchical negative binomial regression models. Results: Higher income (incidence rate ratio [IRR] 0.70, P &lt; 0.001), regular breakfast intake (IRR 0.64, P &lt; 0.001), higher fruit and vegetable consumption (IRR 0.93, P &lt; 0.001), preventive dental check-ups (IRR 0.84, P &lt; 0.001), and frequent toothbrushing (IRR 0.73, P &lt; 0.001) were associated with lower DT. The income-DT association remained significant and its magnitude was only slightly attenuated, after adjusting for OHRBs (IRR 0.74, P &lt; 0.001). Significant interaction effects were found between income and each OHRB on DT (all with P &lt; 0.001), and interaction patterns differed by behavior type: The income-DT association was stronger in the presence of unfavorable dietary-and favorable dental care-behaviors. Conclusion: The study findings suggested that adolescent oral health equity interventions should prioritize the structural approach and give more thorough consideration to the interactions between socioeconomic and behavioral factors.

Do family characteristics contribute to a socioeconomic gradient in overweight in early childhood? – Single mediation analyses of data from German preschool children

Children’s overweight is strongly associated with family socioeconomic position (SEP) and family characteristics (FC). There is limited research on the extent to which FC account for a socioeconomic gradient in childhood overweight. This study examined whether FC explain SEP differences in the prevalence of overweight. The study used baseline data of preschool-aged children from the German ‘PReschool INtervention Study’. The sample (n = 872, 48% girls) was recruited at kindergartens in Baden-Württemberg, Germany. Data included children’s measured weight status and parents’ reports on socioeconomic indicators (e.g., school education, vocational education, income) and FC. Variables represent main determinants of overweight (nutrition: sweets consumption in front of TV, soft drink consumption, regular breakfast, child sets table; physical activity: outdoor sports; parental role model). In single mediation analyses indirect effects of SEP on overweight were analysed (OR[95%CI]). Preschool girls and boys with low parental education had higher odds for overweight than children with high parental education. Among boys, low levels of parental education contributed to the odds of overweight via indirect effects by both factors ‘sweets consumption in front of TV’ (OR = 1.31[1.05–1.59]) and ‘no sports’ (OR = 1.14[1.01–1.38]). Among girls, FC measured did not explain SEP differences in overweight. Family nutrition and parental/family physical activity contribute to inequalities in overweight among preschool boys, but not girls. Research is needed to identify FC that explain inequalities in overweight for both.

A hypothetical intervention of the timing of dietary intake on weight and body composition after initial weight loss.

This study estimated the effect of hypothetical interventions of higher and lower frequency of breakfast and post-dinner snack consumption (breakfast consumption 0-4 vs. 5-7 times/week and post-dinner snack consumption 0-2 vs. 3-7 times/week) on changes in body weight and composition over 18 months after a successful 6-month standard behavioral weight-loss program. The study analyzed data from the Innovative Approaches to Diet, Exercise and Activity(IDEA) study. If all participants consumed a breakfast meal 5 to 7 times/week over 18 months, they would have regained 2.95 kg of body weight on average (95% CI: 2.01 to 3.96), which is 0.59 kg (95% CI: -0.86to -0.32) lower than if all participants consumed breakfast 0 to 4 times/week. If all participants consumed a post-dinner snack 0 to 2 times/week, they would have regained 2.86 kg of body weight on average (95% CI: 0.99 to 5.25), which is 0.83 kg (95% CI: -1.06 to -0.59) lower than if all consumed a post-dinner snack 3 to 7 times/week. Regular breakfast consumption and minimizing post-dinner snacking may modestly mitigate weight and body fat regain over 18 months after initial weight loss.

Breakfast intake and associated factors and barriers among tertiary institution students in the Western Region, Ghana

BackgroundBreakfast is considered the day’s most important meal. Skipping breakfast consumption is detrimental to health and intellectual performance. University life has tight schedules and rigorous intellectual activities often very early in the morning. This study aimed at assessing breakfast intake and its associated factors among the students of Takoradi Technical University (TTU).MethodsThis was a descriptive cross-sectional study. Data was collected from 347 students in TTU using pre-tested questionnaire. Data collected were analysed using STATA v17. It employed descriptive and inferential statistics such as logistic regression. P-value less than 0.05 was set as statistical significance at 95% confidence interval.ResultsRegular breakfast was taken by 35.7% of the students. Higher odds of regular breakfast intake were found among respondents aged 25–29 years (AOR = 3.13, 95%CI = 1.57–6.24) and those who buy their breakfast (AOR = 5.13, 95%CI = 2.16–12.19). However, lower odds of regular breakfast consumption were found among respondents who were females (AOR = 0.40, 95%CI = 0.18–0.85). Barriers to regular breakfast intake included negative mood, insufficient funds, health condition, weight management, religious reasons such as fasting, limited time/unfavourable academic schedules, daily activities/workload, and cost of food on campus.ConclusionThe study stressed on the need for external and personal factors such as sex, age, religion, limited time/unfavourable academic schedules among others that hinder habitual breakfast intake to be addressed adopting innovative approach such as peer education and campaigns. University management should implement favourable policies on academic schedules, canteens/cafeterias, less stringent regulation on cooking at halls of residence.

Breakfast Eating Habits and their Association with Academic Performance: A Cross-sectional Study among Medical Students

Introduction: Breakfast has long been considered the most important meal of the day, yet the frequency of breakfast consumption has declined in recent decades. Adequate breakfast habits are related to optimal physiological, psychological, and social health. Aim: To assess the breakfast eating habits of medical students and find the association between breakfast habits and academic performance. Materials and Methods: A cross-sectional, observational study was carried out in the Department of Physiology at Shaheed Hasan Khan Mewati (SHKM) Government Medical College, Nuh, Haryana, India. The duration of the study was three months from July 2022 to September 2022. A total of 350 apparently healthy medical undergraduates from the second year to final year participated in the study. Breakfast eating patterns and other characteristics of the morning meal consumed by participants were assessed using a structured proforma. Participants were divided into three groups (regular, irregular, and skippers) based on the frequency of breakfast consumption. Academic performance was assessed based on the aggregate marks (%) obtained in the university examination. Data were compiled and analysed using Statistical Package for Social Sciences (SPSS) software version 20.0 (SPSS Inc., Chicago, IL, USA). One-way Analysis of Variance (ANOVA) was used to compare academic performance (% marks) among the breakfast groups, and the relationship between the aforementioned variables was determined using Pearson’s Chi-square test. A p-value of &lt;0.05 was considered statistically significant. Results: The mean age of the study participants was 20.95±1.10 years. Present study showed that only around one-third, 121 (34.6%) students ate breakfast regularly (6-7 days/week), while the remaining either consumed it irregularly or skipped it altogether. A significant association (p=0.02) was found between breakfast habits and academic performance, with regular breakfast eaters performing better compared to skippers. Conclusion: Irregular consumption of breakfast is quite prevalent among medical students. Poor time management emerged as the main reason for this behaviour. Breakfast habits may influence academic performance, but it warrants further investigation using a multivariate approach.

Meal patterns and the quality of breakfast and snacks in relation to adolescents' dental health in southeast of Iran.

Aim: The objective was to determine the frequency pattern and nutritional quality of breakfast and snacks in Iranian adolescents and to investigate these dietary habits in relation to tooth decay and tooth erosion. Methods: A multistage cluster random sampling method was adopted to recruit 600 adolescents with equal sex distribution in the city of Kerman/southeast of Iran. Decayed, Missing and Filled Teeth (DMFT) and Tooth Wear Index (TWI) were recorded for each subject. Snacking and breakfast quality, frequency of snacking and regular/irregular use of main meals were also recorded. Poisson regression and Firth's bias-reduced penalized-likelihood logistic regression were used for data analysis. Results: DMFT score of adolescents who consumed low-quality snacks were 1.13 times more than those who consumed high-quality snacks. Regular use of all three main meals was associated with a lower DMFT score. DMFT score of adolescents who did not have regular use of breakfast was 1.19 times more than those who consumed breakfast on a regular basis. Also, regarding adolescents who had an irregular use of lunch, the DMFT score was 1.3 times more than those who had a regular lunch schedule. In addition, participants with irregular dinner consumption had 1.24 times more DMFT scores compared to those with a regular dinner schedule. Conclusions: Regular breakfast consumption, decreased snacking occasions, use of higher nutritional quality snacks, and increased nutritional education are important in order to prevent a higher chance of dental caries and promote dental health status.
