Skipping Breakfast and Progression of Chronic Kidney Disease in the General Japanese Population: The Iki City Epidemiological Study of Atherosclerosis and Chronic Kidney Disease (ISSA-CKD).

INTRODUCTION: Breakfast-skipping habits are associated with adverse health outcomes including coronary heart disease, metabolic syndrome, and diabetes mellitus. However, it remains uncertain whether skipping breakfast affects chronic kidney disease (CKD) risk. This study aimed to examine the association between skipping breakfast and progression of CKD. METHODS: We retrospectively conducted a population-based cohort study using the data from the Iki City Epidemiological Study of Atherosclerosis and Chronic Kidney Disease (ISSA-CKD). Between 2008 and 2019, we included 922 participants aged 30 years or older who had CKD (estimated glomerular filtration rate <60 mL/min/1.73 m2 and/or proteinuria) at baseline. Breakfast skippers were defined as participants who skipped breakfast more than 3 times per week. The outcome was CKD progression defined as a decline of at least 30% in the estimated glomerular filtration rate (eGFR) from the baseline status. Cox proportional hazards models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for CKD progression, adjusted for other CKD risk factors. RESULTS: During a follow-up period with a mean of 5.5 years, CKD progression occurred in 60 (6.5%) participants. The incidence rate (per 1,000 person-years) of CKD progression was 21.5 in the breakfast-skipping group and 10.7 in the breakfast-eating group (p = 0.029), respectively. The multivariable-adjusted HR (95% CI) for CKD progression was 2.60 (95% CI: 1.29-5.26) for the breakfast-skipping group (p = 0.028) compared with the group eating breakfast. There were no clear differences in the association of skipping breakfast with CKD progression in subgroup analyses by sex, age, obesity, hypertension, diabetes mellitus, baseline eGFR, and baseline proteinuria. CONCLUSION: Skipping breakfast was significantly associated with higher risk of CKD progression in the general Japanese population.

Longitudinal associations of skipping breakfast and night eating with 4-year changes in weight and waist circumference among Chinese adults.

BACKGROUND: The longitudinal association between specific eating behaviors, such as skipping breakfast and night eating, and changes in weight and waist circumference (WC) has been understudied. OBJECTIVES: The objective of this study was to investigate whether skipping breakfast and night eating were individually or jointly associated with the annual changes in weight and WC. METHODS: In the current longitudinal study, included were 48,150 Chinese adults (mean age: 50.1 ± 13.9 y) who were free of diabetes, cardiovascular diseases, and cancer in 2014, when data on dietary intake and the presence of night-eating behavior and skipping breakfast were collected via questionnaires. Weight and WC were measured repeatedly in 2014, 2016, and 2018. The associations between night eating and/or skipping breakfast and annual changes in weight and WC were evaluated using the generalized estimating equation models, adjusting for age, sex, total energy, diet quality, and other potential confounders. RESULTS: During 4-y of follow-up, among people who had both 2 unhealthy eating behaviors, the mean difference in annual weight change was 0.53 kg (95% confidence interval: 0.43, 0.63 kg) and 0.41 cm (95% confidence interval: 0.27, 0.55 cm) in annual WC change, compared with participants without either behavior. The associations of eating behaviors and change in weight and WC were more pronounced in participants with higher baseline body mass index (in kg/m2) relative to their counterparts. Similarly, the associations between these eating behaviors and WC change were stronger in those with poorer diet quality relative to those with better diet quality. CONCLUSIONS: Individuals with frequent skipping breakfast and/or night eating experienced faster gains in weight and WC, even after adjusting for diet quality and energy intake.

Association between breakfast patterns and executive function among adolescents in Shanghai, China.

Introduction: The aim of this cross-sectional study was to investigate the association between breakfast patterns and executive function among adolescents in Shanghai, China. Methods: In 2022, we randomly recruited 3,012 adolescents aged 12-13 years from all administrative districts in Shanghai. Breakfast information was collected by parents using a one-day recall method. Executive function was measured using the Behavior Rating Inventory of Executive Function-Parent Version. Latent Class Analysis was performed to identify breakfast patterns based on the food groups in the Diet Quality Questionnaire for China. Results: Breakfast patterns were classified into three categories: "Egg and milk foods", "Grain foods", and "Abundant foods", except for adolescents who skipped breakfast. Logistic regression was used to estimate the multivariate odds ratio (ORs) and 95% confidence intervals (95% CI) for the association between breakfast patterns and potential executive dysfunction. Adolescents in the "Abundant foods" class had a lower risk of executive dysfunction in terms of initiate (OR: 0.36; 95% CI: 0.17-0.76), and organization of materials (OR: 0.18; 95% CI: 0.04-0.94), compared to those who skipped breakfast. Similarly, the breakfast patterns of "Grain foods" and "Egg and milk foods" were associated with a lower risk of executive dysfunction, including initiate and working memory. Discussion: Our findings suggest that breakfast patterns were associated with executive function. The improvement of breakfast patterns among adolescents should be a significant public health intervention.

Association between breakfast consumption, breakfast quality, mental health and quality of life in Turkish adolescents: A high school-based cross-sectional study.

This study aimed to determine the frequency of breakfast consumption and breakfast quality among adolescents and to evaluate the relationships between breakfast consumption, breakfast quality, mental health, and health-related quality of life. This cross-sectional study included 449 students from 17 high schools between December 2022 and May 2023. A face-to-face questionnaire measuring the frequency of breakfast consumption, Mediterranean diet quality index (KIDMED), health-related quality of life (KIDSCREEN), and depression, anxiety and stress scales (DASS-21) was performed. Of the students, 54.1% skipped breakfast 2 or more times a week and 75.9% had poor breakfast quality. There were significant differences in breakfast quality classification according to the frequency of breakfast consumption (p = 0.003). Breakfast consumption ≤1 time/week or 2-5 times/week was associated with depression, anxiety and low adherence to the Mediterranean diet. No relationship was observed between breakfast quality and stress, depression or anxiety (p = 0.620, p = 0.586, p = 0.539, respectively) or between breakfast quality and the KIDSCREEN-27 subscales (p > 0.05). However, those eating poor-quality breakfasts had better results in physical wellbeing (p = 0.022), psychological wellbeing (p = 0.024), autonomy and parent relations (p = 0.017) than breakfast-skippers and also scored lower for depression, stress and anxiety (all p < 0.001). In conclusion, the frequency of breakfast consumption had a stronger association with reduced symptoms of stress, depression and anxiety, as well as improvements in all dimensions of health-related quality of life, compared to the quality of breakfast consumed. Given the association of breakfast consumption with mental health outcomes in adolescents, our findings are of great importance, especially to parents, clinicians and nutritional educators.

Examining the association of breakfast skipping with sleep disturbance, mental health, and health-related quality of life: data from the 2018 Korean community health survey.

Objectives: This study aimed to explore the relationship between breakfast skipping and its effects on sleep disorders, mental health, and health-related quality of life among Korean adults.Methods: Utilizing data from the 2018 Korea Community Health Survey, this cross-sectional analysis included 173,272 adults aged 19 years and older. Instruments used for assessment included the Patient Health Questionnaire-9 for depression, the EuroQol 5-dimension (EQ-5D) for health-related quality of life, and the Pittsburgh Sleep Quality Index for sleep disorders. The complex sample logistic regression analysis was employed to adjust for potential confounders.Results: Breakfast skipping was found to be significantly associated with delayed mid-sleep time, an increased propensity for daytime sleepiness, and a notable decline in sleep quality. Additionally, it was linked to a significant increase in depression risk, compromised health-related quality of life, and elevated stress levels across both genders. All five dimensions of the EQ-5D were negatively impacted by breakfast skipping.Discussion: The findings highlight the detrimental effects of skipping breakfast on sleep patterns, mental health, and overall quality of life, stressing the importance of regular breakfast consumption for enhancing these health outcomes. The study suggests the need for further research to uncover the mechanisms behind these associations and to devise targeted interventions to mitigate the negative impacts of breakfast skipping.

Effect of skipping breakfast on cardiovascular risk factors: a grade-assessed systematic review and meta-analysis of randomized controlled trials and prospective cohort studies.

Skipping breakfast is one of the most prevalent irregular eating habits. Several pieces of evidence have reported the association between breakfast omission and a higher risk of cardiovascular diseases. Numerous publications have focused on the impact of skipping breakfast on various cardiovascular risk factors. Therefore, the current systematic review and meta-analysis aimed to assess this impact, especially with regard to anthropometric measurements, serum lipid profiles, blood pressure, and glycemic control indicators. A comprehensive search was performed in PubMed, Web of Science, Embase, Scopus, and the Cochrane Central Register of Controlled Trials up to 1 April 2023. A total of 11 eligible trials were identified to evaluate the combined effects of skipping breakfast. Final integrated results demonstrated that breakfast omission significantly decreased the body weight (mean difference = -0.66, 95% CI: -1.09 to -0.24, p = 0.002, I2 = 0.0) and increased the level of serum low-density lipoprotein cholesterol (LDL-C) (mean difference = 9.89, 95% CI: 5.14 to 14.63, p = 0.000, I2 = 17.3). Subgroup analysis also revealed potential factors that may affect the outcomes, for example, the physiological condition of participants, duration, gender, and type of breakfast. In conclusion, skipping breakfast may reduce body weight while increasing the level of serum LDL-C at the same time. In view of the limited trials, further studies are needed to expound the role of breakfast omission in cardiovascular diseases.

Association of gastrointestinal symptoms and skipping breakfast with anxiety and depressive symptoms in quarantined Chinese college students during the Shanghai 2022 lockdown: a cross sectional survey.

BACKGROUND: This study aimed to evaluate the prevalence of anxiety and depressive symptoms among quarantined college students at school in Shanghai 2022 lockdown during the COVID-19 pandemic and investigate the association of gastrointestinal discomfort related-factors and skipping breakfast with anxiety and depressive symptoms. METHODS: 384 quarantined college students in Shanghai China were recruited in this cross-sectional study from April 5th to May 29th, 2022. Generalized Anxiety Disorder (GAD-7) and Patient Health Questionnaire (PHQ-9) were used to assess anxiety and depressive symptoms, respectively. RESULTS: The prevalence of anxiety and depressive symptoms were 56.8% and 62.8%, respectively. Longer quarantine duration, higher education level, skipping breakfast, stomachache or abdominal pain, and nausea or dyspepsia were significantly associated with anxiety symptoms. Moreover, longer quarantine duration, being woman, skipping breakfast, stomachache or abdominal pain, and nausea or dyspepsia were markedly related to depressive symptoms. Notably, regularly physical exercising and taking positive attitude towards COVID-19 were negatively correlated with anxiety and depressive symptoms. CONCLUSIONS: More attention should be paid to anxiety and depressive symptoms of quarantined college students and universities should provide timely psychological monitoring and intervention services to mitigate the impact of negative emotions on students. Effectively relieving gastrointestinal symptoms, insisting on eat breakfast, regularly exercising, and taking a positive attitude towards to COVID-19 might contribute to preventing the anxiety and depressive symptoms for those college students experiencing a long-term quarantine.

The association between skipping breakfast and chronic kidney disease.

BACKGROUND/OBJECTIVES: There are few reports on the relationship between skipping breakfast and chronic kidney disease (CKD). We examined the skipping breakfast-CKD relationship and the mediation effects of metabolic diseases (obesity, hypertension, and diabetes) on this relationship. SUBJECTS/METHODS: We analyzed the data of 21,138 participants aged ≥ 40 years from the Korea National Health and Nutrition Examination Survey 2013-2018. Skipping breakfast was defined as rarely eating breakfast over the past year. CKD was defined as decreased kidney function expressed by an estimated glomerular filtration rate of < 60 mL/min/1.73 m2. We used a complex sample logistic regression model to examine the relationship between skipping breakfast and CKD. We used Baron and Kenny's approach to examine whether metabolic diseases work as a mediator within the skipping breakfast-CKD relationships. RESULTS: About 7.6% of participants skipped breakfast, and 5.5% had CKD. After adjusting for confounders, participants who skipped breakfast were at higher odds of having CKD (odds ratio 1.61; 95% confidence interval 1.07-2.42; p value 0.021) compared to those who did not skip breakfast. With full adjustments for confounders, skipping breakfast was not significantly associated with any metabolic diseases, while CKD was significantly associated with diabetes and hypertension. CONCLUSION: We found that middle-aged or older people who skipped breakfast had a significantly higher odds of having CKD compared to those who did not skip breakfast. However, metabolic diseases did not mediate the relationship between skipping breakfast and CKD.

Association between skipping breakfast and prediabetes among adolescence in Japan: Results from A-CHILD study.

Objective: Adolescents with prediabetes are at high risk of developing type 2 diabetes in later life. It is necessary to identify risk factors for prediabetes in adolescents. This study aimed to examine the association between skipping breakfast and prediabetes among adolescents in Japan. Study design: We used the population-based cross-sectional data of eighth grade in junior high school students from the Adachi Child Health Impact of Living Difficulty (A-CHILD) study conducted in Adachi City, Tokyo, Japan, in 2016, 2018, and 2020. Skipping breakfast was assessed using self-reported questionnaires (N=1510). Prediabetes was defined as hemoglobin A1c (HbA1c) levels of 5.6-6.4%. The association between skipping breakfast and prediabetes was evaluated using multivariate logistic regression analysis. Stratified analysis was also performed using BMI, 1 SD or more, or less than 1SD, as overweight was defined as 1SD or more. Results: Students who skipped breakfast were 16.4% (n=248). The prevalence of prediabetes was 3.8% (n=58). Skipping breakfast exhibited a significant association with prediabetes (OR:1.95, 95% CI: 1.03 to 3.69) after adjusting for sex, annual household income, family history of diabetes mellitus, BMI, and survey year. Stratified analysis showed stronger association among students with overweight (BMI ≥1SD) (OR=4.31, 95% CI 1.06-17.58), while non-sigificant among students without overweight (BMI<1SD) (OR=1.62, 95% CI 0.76-3.47). Conclusions: Skipping breakfast in Japanese adolescents, especially those with overweight, was associated with prediabetes. The promotion of avoiding skipping breakfast may help to prevent prediabetes.

Consumption and Breakfast Patterns in Children and Adolescents with Congenital Heart Disease.

Little is known about skipping breakfast and breakfast patterns (BP) and their evaluation according to sociodemographic, clinical, lifestyle, cardiometabolic and nutritional data in children and adolescents with congenital heart disease (CHD). This cross-sectional study with 232 children and adolescents with CHD identified the prevalence and patterns of the breakfast, described these according to sociodemographic, clinical and lifestyle characteristics, and assessed their association with cardiometabolic and nutritional markers. Breakfast patterns were identified by principal components, and bivariate and linear regression analysis were applied. Breakfast consumption was observed in 73% of participants. Four BP were identified: pattern 1 "milk, ultra-processed bread, and chocolate milk", pattern 2 "margarine and processed bread", pattern 3 "cold meats/sausages, cheeses and butter/cream" and pattern 4 "fruits/fruit juices, breakfast cereals, yogurts, and homemade cakes/pies and sweet snacks". Family history for obesity and acyanotic CHD were associated with breakfast skipping. Younger participants and greater maternal education were associated with greater adherence to pattern 1 and pattern 4. Older participants and longer post-operative time showed greater adherence to pattern 3. No association between skipping breakfast or BP and cardiometabolic and nutritional markers was observed. Nonetheless, the findings reinforce the need for nutritional guidance for healthy breakfast, aiming to reduce the consumption of ultra-processed foods and to prioritize fresh and minimally processed foods.

Skipping breakfast is associated with being overweight among Brazilian adolescents

Objective: To evaluate the association between skipping breakfast and overweight among Brazilian adolescents. Methods: A total of 16,556 Brazilian students (aged 11-19 years) who participated in the National School Health Survey in 2015 were evaluated. The omission of breakfast (consumption frequency <5 days/week) was determined using the question, "Do you usually have breakfast"? The participants' weight and height were measured, and excess weight was classified according to the body mass index for sex and age. The covariates analyzed were sociodemographic and economic characteristics (sex, age group, socioeconomic status, skin color, maternal schooling, paid work, and living with parents); variables related to school (administrative dependence, study shift, and presence of a canteen); lifestyle (physical activity, alcohol consumption, smoking, sedentary behavior, consumption of industrialized foods, meals with parents, and school meals); and self-perception of body image. The association between skipping breakfast and being overweight was analyzed using a Poisson regression model with adjustment for covariates. Results: The prevalence of skipping breakfast and being overweight were 33.8% and 25.2%, respectively. After adjustment, skipping breakfast was associated with being overweight (OR:1.02; 95% CI:1.01; 1.04). Conclusion: Skipping breakfast is associated with being overweight among Brazilian adolescents. Thus, encouraging regular consumption of meals should be part of health promotion and healthy eating actions aimed at preventing diseases and chronic noncommunicable diseases.

Objetivo: Evaluar la asociación entre la omisión del desayuno y el sobrepeso entre adolescentes brasileños. Métodos: Fueron evaluados 16.556 estudiantes brasileños (de 11 a 19 años) que participaron en la Encuesta Nacional de Salud Escolar en 2015. La omisión del desayuno (frecuencia de consumo < 5 días/semana) se determinó mediante la pregunta "¿Desayuna habitualmente"? Se midió el peso y la talla de los participantes, y se clasificó el exceso de peso según el índice de masa corporal para el sexo y la edad. Las covariables analizadas fueron características sociodemográficas y económicas (sexo, grupo de edad, nivel socioeconómico, color de piel, escolaridad materna, trabajo remunerado y convivencia con los padres); variables relacionadas con la escuela (dependencia administrativa, turno de estudio y presencia de comedor); estilo de vida (actividad física, consumo de alcohol, tabaquismo, sedentarismo, consumo de alimentos procesados, comidas con los padres y alimentación escolar); y autopercepción de la imagen corporal. La asociación entre saltarse el desayuno y tener sobrepeso se analizó mediante un modelo de regresión de Poisson con ajuste por covariables. Resultados: La prevalencia de saltarse el desayuno y tener sobrepeso fue de 33,8% y 25,2%, respectivamente. Después del ajuste, saltarse el desayuno se asoció con sobrepeso (OR: 1,02; IC 95 %: 1,01; 1,04). Conclusión: Saltarse el desayuno está asociado con el sobrepeso entre los adolescentes brasileños. Por lo tanto, fomentar el consumo regular de comidas debe ser parte de las acciones de promoción de la salud y alimentación saludable dirigidas a la prevención de enfermedades y enfermedades crónicas no transmisibles.

Assessment of skipping breakfast at home among adolescent school students in Badia Region, Jordan

@#Introduction: Healthy meals play an essential role in the healthy physical and mental development of adolescents. Breakfast at home is associated with improved nutritional choices, and skipping breakfast is detrimental. This study assessed prevalence of skipping breakfast at home among adolescent students in the Badia Region of Jordan, identifying the reasons and characteristics associated with such behavioural choice. Methods: A cross-sectional survey among adolescent students (aged 13-16 years, in 8th-9th grades) from six public schools in Badia Region, Mafraq Governorate, Jordan, was conducted through self-administered questionnaire from February to March 2022. Results: Results showed that 68.1% of 552 student participants regularly skipped breakfast at home (72.4% boys vs. 61.3% girls; p=0.007). Among those who regularly skipped breakfast, three main rationales for this choice were not feeling hungry (5.3%), lack of time (2.7%), and lack of appetite (3.5%). Conclusion: The prevalence of skipping breakfast at home among adolescents in Badia Region was high for various reasons, including lack of time, not feeling hungry, seeking to manage weight, and insufficient knowledge on the importance of healthy breakfast. Therefore, understanding the reasons and factors that contribute towards breakfast skipping may help in solving the problem, underscoring that positive beliefs should be reinforced in schools, with parents encouraging adolescents to eat healthy breakfast.

Skipping breakfast during pregnancy and hypertensive disorders of pregnancy in Japanese women: the Tohoku medical megabank project birth and three-generation cohort study.

BACKGROUND: Hypertensive disorders of pregnancy (HDP) adversely affect the prognosis of mother and child, and the prognosis depends on the subtype of HDP. Skipping breakfast may be associated with increased blood pressure due to disruption of the circadian clock, but the association with the development of HDP has not been studied. The purpose of this study was to examine the association between skipping breakfast and the development of HDP and HDP subtypes in Japanese pregnant women. METHODS: Of the pregnant women who participated in the Tohoku Medical Megabank Project Three-Generation Cohort Study, 18,839 who answered the required questions were included in the analysis. This study had a cross-sectional design. The breakfast intake frequency from pre-pregnancy to early pregnancy was classified into four groups: daily, 5-6 times per week, 3-4 times per week, and 0-2 times per week. HDP was classified into gestational hypertension (GH), chronic hypertension (CH), preeclampsia (PE), and severe preeclampsia (SuPE). Multiple logistic regression analysis and multinomial logistic analysis were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for breakfast intake frequency and development of HDP or HDP subtypes. We performed a stratified analysis based on energy intake. RESULTS: Of the participants, 74.3% consumed breakfast daily, and 11.1% developed HDP. Women who consumed breakfast 0-2 times per week had a higher risk of HDP (OR: 1.33, 95% CI: 1.14-1.56), CH (OR: 1.63, 95% CI: 1.21-2.19), and PE (OR: 1.68, 95% CI: 1.27-2.21) than those who consumed breakfast daily. No association was found between skipping breakfast and the risk of developing GH (OR: 1.26, 95% CI: 0.99-1.61) and SuPE (OR: 0.91, 95% CI: 0.55-1.49). Stratified analysis showed that the risk of developing HDP due to skipping breakfast was highest in the group with the highest daily energy intake. CONCLUSIONS: Skipping breakfast during pre-to early pregnancy is associated with the development of HDP. Further longitudinal studies are required to clarify the causal association between skipping breakfast and HDP.

Lower body mass index potentiates the association between skipping breakfast and prevalence of proteinuria.

Background: Proteinuria is an important predictor of cardiovascular disease and mortality. Several studies reported the association between skipping breakfast and the prevalence of proteinuria. Furthermore, skipping breakfast was associated with an increased risk of obesity. Although proteinuria is highly prevalent in obese individuals, the association between the prevalence of proteinuria and low body mass index (BMI) was reported in a previous cross-sectional study in asymptomatic individuals without known kidney diseases. The aim of this cross-sectional study was to assess the clinical impact of BMI on the association between skipping breakfast and the prevalence of proteinuria in normal renal function subjects. Methods: The present study included 26,888 subjects (15,875 males and 11,013 females) with an estimated glomerular filtration rate ≥60 ml/min/1.73 m2 and no history of kidney disease who underwent a health checkup in Sumitomo Hospital. The association between skipping breakfast and the prevalence of proteinuria (defined as dipstick proteinuria of ≥1+) was assessed using logistic regression models adjusted for clinically relevant factors. Results: Skipping breakfast was reported in 3,306 males (20.8%) and 1,514 females (13.8%). Multivariable adjusted logistic regression models showed that skipping breakfast was significantly associated with the prevalence of proteinuria above 1+. This association was evident in lower BMI subjects, even after adjusting for clinically relevant factors (adjusted odds ratios of males and females were 1.67 [1.17-2.38] and 1.92 [1.31-2.82], respectively), whereas this association was not evident in higher BMI subjects. Conclusion: Lower BMI subjects with proteinuria might need to be careful about skipping breakfast.

Sustained effect of habitual feeding time on daily rhythm of core body temperature in mice.

Background and aim: Circadian clocks in most peripheral tissues are entrained mainly by feeding. Therefore, this study aimed to investigate whether the daily rhythm of core body temperature (CBT), including the effect of diet-induced thermogenesis, varies according to habitual feeding time. Methods: Wild-type and uncoupling protein 1 (UCP1) knockout mice were fed only during the first 4 h (Breakfast group) or the last 4 h of the dark period (Dinner group) for 17 days. On day 18, both groups were fed twice for 2 h, at the same starting times. Locomotor activity and CBT were measured continuously during the experiment. Results: On day 18, CBT increased at the beginning of each feeding period, regardless of the group and strain. However, the CBT increase induced by the first meal decreased sharply in the Breakfast group and mildly in the Dinner group; the opposite was observed after the second meal. In UCP1 knockout, but not wild-type, mice, the total amount of CBT was significantly lower in the Dinner group than in the Breakfast group. These effects were mostly independent of the locomotor activity and food intake. Conclusion: These results reveal that the effect of habitual feeding time on the daily rhythm of CBT is sustained at least until the following day. These effects may be mediated by both UCP1-dependent and -independent mechanisms.

Skipping Breakfast and Incidence of Frequent Alcohol Drinking in University Students in Japan: A Retrospective Cohort Study.

Frequency of alcohol drinking is a potential predictor of binge drinking of alcohol, a serious social problem for university students. Although previous studies have identified skipping breakfast as a predictor of various health-compromising behaviors and cardiometabolic diseases, few studies have assessed the association between skipping breakfast and the incidence of frequent alcohol drinking. This retrospective cohort study included 17,380 male and 8799 female university students aged 18-22 years admitted to Osaka universities between 2004 and 2015. The association between breakfast frequency (eating every day, skipping occasionally, and skipping often/usually) and the incidence of frequent alcohol drinking, defined as drinking ≥4 days/week, was assessed using multivariable-adjusted Cox proportional hazards models. During the median observational period of 3.0 years, 878 (5.1%) men and 190 (2.2%) women engaged in frequent alcohol drinking. Skipping breakfast was significantly associated with the incidence of frequent alcohol drinking (adjusted hazard ratios [95% confidence interval] of eating every day, skipping occasionally, and skipping often/usually: 1.00 [reference], 1.02 [0.84-1.25], and 1.48 [1.17-1.88] in men; 1.00 [reference], 1.60 [1.03-2.49], and 3.14 [1.88-5.24] in women, respectively). University students who skipped breakfast were at a higher risk of frequent alcohol drinking than those who ate breakfast every day.

The Association Between Lifestyle and Abdominal Obesity Among Postmenopausal Women: A Cross-Sectional Study.

Background: This study examined the association between sedentary behavior, sleep duration, breakfast skipping, and abdominal obesity among postmenopausal women in South Korea. Materials and Methods: A total of 7,270 postmenopausal women were included in this cross-sectional, secondary analysis study, using a nationally representative dataset from the Korea National Health and Nutrition Examination Survey. Results: Sleep duration of fewer than 5 hours/day was associated with an increased risk of abdominal obesity (odds ratio [OR] = 1.29; 95% confidence interval [CI], [1.02-1.63]), compared to sleep duration of 6-8 hours/day after controlling for covariates. Additionally, breakfast skipping was associated with an increased risk of abdominal obesity (OR = 1.45; 95% CI [1.02-2.06]), compared to breakfast eating after covariate adjustment. There was no significant association between sedentary behavior and abdominal obesity. Conclusions: The findings of this study demonstrate that special consideration should be given to behavior modification strategies to improve sleep duration and decrease breakfast skipping to decrease the risk of abdominal obesity in postmenopausal women.

Skipping breakfast regimen induces an increase in body weight and a decrease in muscle weight with a shifted circadian rhythm in peripheral tissues of mice.

Meal timing is a key factor in synchronising the circadian clock in peripheral tissues. Circadian disorders are associated with the metabolic syndrome. Previously, we demonstrated that a skipping breakfast regimen (SBR) with a high-fat diet increased body weight gain in rats. In this study, we investigated whether SBR with a normal diet led to abnormal lipid metabolism and muscle metabolism in mice. Male C57BL/6 mice were fed during zeitgeber time (ZT) 12-24 in the control group and ZT 16-24 in the SBR group for 2 weeks. SBR mice showed increased body weight gain and perirenal adipose tissue weight. The plantar muscle weight was decreased in the SBR group compared with that in the control group. Furthermore, SBR delayed the circadian oscillations in clock gene expression in peripheral tissues, such as the liver, adipose tissue and muscle, as well as the oscillations in the expression of lipid metabolism-related genes in the liver and adipose tissue. These results suggest that skipping breakfast over a long period of time is associated with a risk of obesity, the metabolic syndrome and muscle loss, such as sarcopenia.

Investigating the Association between Unhealthy Dietary Habits and Obesity among Libyan Adults.

BACKGROUND: Although an increasing number of studies have reported on nutrition transition and unhealthy eating habits (UEHs) worldwide, there is a paucity of studies on UEHs in the Arab region, particularly in Libya. Aim: This study investigated the associations between obesity among Libyan adults and UEHs. Methods: A cross-sectional survey was conducted at the five major districts in Benghazi, Libya. A multistage cluster sampling strategy was implemented to choose and recruit Libyan adults. Anthropometric measurements were gathered by highly qualified nurses, using the Segmental Body Composition Monitor and a portable Stadiometer. The study used and adapted the two Self-administered questionnaires: the WHO STEPS Instrument and eating behaviors linked with obesity questionnaire. Results: Among a total of 401 participants who were successfully recruited in this study, 253 (63%) were female (aged 20-65 years), the response rate achieved was 78%. The prevalence of obesity amongst Libyan adults was estimated to be 42.4%. The results revealed the presence of a significant association between obesity (BMI ≥ 30 kg/m2) and five UEHs for Libyan men and six UEHs for Libyan women. For Libyan men, an association was found between obesity and the following five explanatory factors: fast food intake in a day and a week, which were (OR: 2.52, 95% CI: 4.04-12.32) and (OR: 4.65, 95% CI: 1.04-9.46), respectively; large food portion sizes consumed at one sitting (OR: 19.54, 95% CI: 1.41-27.74); a high frequency of skipping breakfast either in a typical day or a week, which were (OR: 0.02, 95% CI: 0.01-0.77) and (OR: 0.03, 95% CI: 0.01-0.24), respectively. For Libyan women, a significant association was found between obesity and the following six explanatory factors: fast food intake in a day and a week, which were (OR: 2.14, 95% CI: 3.32-11.12) and (OR: 5.5, 95% CI: 1.88-16.11), respectively; intake of sugar-sweetened beverages in a typical week (OR: 4.02, 95% CI: 1.35-11.99); and large food portion sizes consumed at one sitting at one sitting (OR: 3.40, 95% CI: 1.18-9.84); and a high frequency of skipping breakfast either in a typical day or a week, which were (OR: 0.11, 95% CI: 0.03-0.43) and (OR: 0.12, 95% CI: 0.08-0.63), respectively. Conclusions: The findings of the study reveal areas of action for Libyan researchers, clinicians, policymakers, and government officials about UEHs in the Libyan context. This could inform establishing and developing new interventions for preventing and controlling the obesity epidemic through food system improvements.

Eating habits are associated with subjective sleep quality outcomes among university students: findings of a cross-sectional study.

PURPOSE: This study investigated the relationships between eating habits and sleep quality among university students. METHODS: In a cross-sectional study, university students completed a self-report questionnaire to assess eating habits and meal timing. We assessed subjective sleep quality using the Pittsburgh Sleep Quality Index (PSQI) questionnaire and examined the associations between eating habits and overall sleep quality and its components. RESULTS: Four hundred ninety-eight students participated in the study. Students who used to skip breakfast, ate late-night snacks, and replaced meals with snacks were at 1.20 times, 1.24 times, and 1.25 times higher likelihood of having poor overall sleep quality, respectively. Multiple logistic regression analysis showed that skipping breakfast (r = - 0.111, P = 0.007), late-night snacks (r = - 0.109, P = 0.007), replacing meals with snacks (r = - 0.126, P = 0.002), and irregular mealtimes (r = - 0.094, P = 0.018) were the best correlates with poor sleep quality. After adjustment to demographic variables, replacing meals with snacks followed by skipping breakfast were the best independent associations with poor sleep quality by the PSQI. CONCLUSIONS: Eating habits and meal timing were significantly associated with sleep quality. We speculate that healthy eating habits may lead to improved sleep quality and sleep components among university students.
