Reprod Biomed Online 2024; 48:103700. [PMID: 38367594 DOI: 10.1016/j.rbmo.2023.103700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 10/17/2023] [Accepted: 11/06/2023] [Indexed: 02/19/2024]
Abstract
RESEARCH QUESTION What is the contribution of sociodemographic, psychosocial, lifestyle and reproductive factors up to the age of 11-12 years to the occurrence of dysmenorrhoea at age 15-16 years within the Amsterdam Born Children and their Development (ABCD) study? DESIGN Data of 1038 female adolescents were used. Participants' baseline characteristics were obtained using self-reported questionnaires up to the age of 11-12 years, as well as the obstetric information of their mothers during pregnancy. Dysmenorrhoea was assessed at the age of 15-16 years, and was deemed to be present if an adolescent reported menstrual abdominal and/or back pain and therefore took medication and/or hormonal contraception. Using a backward selection approach, potential determinants of dysmenorrhoea were selected and multivariable associations were determined. RESULTS The overall prevalence of dysmenorrhoea was 49.5% among the participants. Intake of 3-4.5 sugar-sweetened beverages/day (P = 0.035) and higher gynaecological age (i.e. years since menarche) (P < 0.001) were significantly associated with higher occurrence of dysmenorrhoea in the final model, which explained 8.1% of the total variance in the occurrence of dysmenorrhoea. No significant associations were found between the occurrence of dysmenorrhoea and sociodemographic or psychosocial factors. CONCLUSIONS This investigation of various potential risk factors for dysmenorrhoea suggests that diet and reproductive factors are particularly important predictors of the occurrence of dysmenorrhoea among young adolescents. Specifically, intake of sugar-sweetened beverages and higher gynaecological age were predictive of the occurrence of dysmenorrhoea. Other lifestyle factors were also identified as possible risk factors. Using this knowledge, effective strategies can be developed to reduce the burden of dysmenorrhoea among adolescents, and to provide appropriate care for those suffering from the condition.

Skipping breakfast and its association with sociodemographic characteristics, night eating syndrome, and sleep quality among university students in Bangladesh. BMC Nutr 2024; 10:46. [PMID: 38439041 PMCID: PMC10913273 DOI: 10.1186/s40795-024-00860-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 02/27/2024] [Indexed: 03/06/2024] Open
Abstract
INTRODUCTION Skipping breakfast has become more common, and it can significantly affect a person's health, performance, mood, and other physiological and psychological factors. In Bangladesh, university students often encounter unhealthy dietary habits, which raises questions about why many university students choose to skip breakfast. The purpose of this study was to investigate the prevalence of skipping breakfast among university students in Bangladesh and explore the contributing factors. METHODS Patuakhali Science and Technology University, Bangladesh was the location of this cross-sectional study. Breakfast consumption was measured with the single-question item, "How often do you eat breakfast?" (Almost every day, sometimes, rarely, or never). Skipping breakfast was classified as respondents selecting sometimes, rarely, or never having breakfast. Sociodemographic, behavioral, and sleep-related data were collected as key predictor variables. Multiple logistic regression models identified factors associated with skipping breakfast. RESULTS The prevalence of skipping breakfast among study participants (N = 502, 51.6% female and mean age 21.31 years) was 63.5%. Female students were more likely to skip breakfast compared to male students (adjusted odds ratio, AOR = 1.65, 95% CI: 1.06-2.55). Smoker participants had a higher likelihood of skipping breakfast compared to non-smokers (AOR = 3.92, 95% CI: 1.57-9.78). Students with night eating syndrome had a higher likelihood of skipping breakfast compared to their counterparts (AOR = 1.84, 95% CI: 1.06-3.22). Students with poor sleep quality were three times more likely to skip breakfast than their counterparts (AOR = 2.95, 95% CI: 1.93-4.51). Overweight/obese students were less likely to skip breakfast compared to their counterparts (AOR = 0.40, 95% CI: 0.20-0.82). CONCLUSION This study highlights a high prevalence of skipping breakfast among university students in Bangladesh. Specifically, students who are females, smokers, poor sleepers and who have night eating syndrome are more likely to skip breakfast compared to their counterparts. These findings underscore a need for targeted interventions and educational programs to promote healthy breakfast habits. Addressing these modifiable risk factors can have a positive impact on students' nutritional practices and their health and wellbeing.

Abstract
BACKGROUND Dysmenorrhea is associated with breakfast skipping in young women, suggesting that fasting in the early active phase disrupts uterine functions. OBJECTIVES To investigate the possible involvement of the uterine clock system in fasting-induced uterine dysfunction, we examined core clock gene expressions in the uterus using a 28-h interval-fed mouse model. METHODS Young female mice (8 wk of age) were divided into 3 groups: group I (ad libitum feeding), group II (time-restricted feeding, initial 4 h of the active period every day), and group III (time-restricted feeding for 8 h with a 28-h cycle). Groups II and III have the same fasting interval of 20 h. After analyzing feeding and wheel running behaviors during 2 wk of dietary restriction, mice were sacrificed at 4-h intervals, and the expression profiles of clock genes in the uterus and liver were examined by qPCR. RESULTS The mice in group I took food mainly during the dark phase and those in group II during the initial 4 h of the dark phase, whereas those in group III delayed feeding time by 4 h per cycle. In all groups, spontaneous wheel running was observed during the dark phase. There was no difference in the quantity of feeding and the amount of running exercise among the 3 groups during the second week. The mRNA expressions of peripheral clock genes, Bmal1, Clock, Per1, Per2, Cry1, Nr1d1, and Dbp and a clock-controlled gene, Fabp1, in the uterus showed rhythmic oscillations with normal sequential expression cascade in groups I and II, whereas their expressions decreased and circadian cycles disappeared in group III. In contrast, liver core clock genes in group III showed clear circadian cycles. CONCLUSIONS Fluctuations in the timing of the first food intake impair the uterine clock oscillator system to reduce clock gene expressions and abolish their circadian rhythms.

Front Nutr 2023; 10:1079069. [PMID: 36819675 PMCID: PMC9936822 DOI: 10.3389/fnut.2023.1079069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Accepted: 01/13/2023] [Indexed: 02/05/2023] Open
Abstract
Introduction Students in colleges are exposed to unhealthy lifestyles and poor dietary choices. They are at risk of being overweight, skipping meals, and developing eating disorders. However, there is a paucity of information on their chrononutrition behavior, which is very important, especially concerning the timing of food consumption across the day. Therefore, the present study aimed to investigate chrononutrition behavior and its potential association with body weight status among college students in Malaysia. Methods This cross-sectional study was conducted on 409 college students aged above 18 in Malaysia. The chrononutrition behavior was assessed using the validated Chrononutrition Profile Questionnaire (CP-Q). The questionnaire was distributed using an online platform. Participants self-reported their body weight and height, and the Body Mass Index (BMI) was computed. Data were analyzed using the SPSS software. Results A total of 409 participants were recruited, with a mean age of 21.5 ± 2.2 years. The prevalence of underweight, normal, and overweight was 24.7, 49.4, and 25.9%, respectively. The chrononutrition behavior revealed that participants ate breakfast about four times/week (mean 4.27 ± 2.43 days), and only 135 (33.0%) consumed breakfast daily. The largest meal consumed was during lunch (75.8%), and the mean of snacking after the last meal was 3.23 ± 2.01 days. The prevalence of night eating was low, and most participants (70.9) did not wake up at night to eat. The frequency, however, was significantly higher in the underweight group compared to the normal weight group (p < 0.05). We observed a significant association between BMI and eating window, evening latency, evening eating, and night eating. It was found that the underweight had a poor eating window (p < 0.01), poor evening latency (p < 0.01), poor evening eating (p < 0.01), and poor night eating (p < 0.05) compared to those with normal and overweight BMI groups. In contrast to predictions, poor chrononutrition behavior was more likely to predict being underweight compared to normal (p < 0.05). Conclusion Underweight young adults are more likely to have poor chrononutrition behavior. The results of the present study suggest that future nutrition education should also focus on the chrononutrition behavior of college students.

Abstract
The circadian rhythm, which is necessary for reproduction, is controlled by clock genes. In the mouse uterus, the oscillation of the circadian clock gene has been observed. The transcription of the core clock gene period (Per) and cryptochrome (Cry) is activated by the heterodimer of the transcription factor circadian locomotor output cycles kaput (Clock) and brain and muscle Arnt-like protein-1 (Bmal1). By binding to E-box sequences in the promoters of Per1/2 and Cry1/2 genes, the CLOCK-BMAL1 heterodimer promotes the transcription of these genes. Per1/2 and Cry1/2 form a complex with the Clock/Bmal1 heterodimer and inactivate its transcriptional activities. Endometrial BMAL1 expression levels are lower in human recurrent-miscarriage sufferers. Additionally, it was shown that the presence of BMAL1-depleted decidual cells prevents trophoblast invasion, highlighting the importance of the endometrial clock throughout pregnancy. It is widely known that hormone synthesis is disturbed and sterility develops in Bmal1-deficient mice. Recently, we discovered that animals with uterus-specific Bmal1 loss also had poor placental development, and these mice also had intrauterine fetal death. Furthermore, it was shown that time-restricted feeding controlled the uterine clock's circadian rhythm. The uterine clock system may be a possibility for pregnancy complications, according to these results. We summarize the most recent research on the close connection between the circadian clock and reproduction in this review.

Abstract
There is a growing consciousness about chrono-nutrition and its physiological functions. The human feeding pattern establishes three meals a day, meal timing however may not be adhered to. Previous studies have reported ovarian dysfunctions in breakfast skipping among females. In this study, the investigation was carried out on the effects of breakfast skipping on reproductive functions in the male rat and comparison, to the female rat. Eight-week-old animals (10 rats per group) were used to mimic post-adolescence. Rats are active at night thus the meal model was divided as follows. Female rats who had all three meals (ControlF), Female rats who had a no-first-active meal (NFAMF), Male rats who had all three meals (ControlM), and Male rats who had a no-first-active meal (NFAMM). All animals were fed the same amount of food every day. After the expiration of the four weeks experiment, serum testosterone, estrogen, Luteinising Hormone (LH) Follicle Stimulating Hormone (FSH), and prolactin (PRL) were quantified using ELISA. Sperm was also analyzed. There was a significant increase (p < 0.05) in the testosterone level and sperm count in the NFAMM compared to the ControlM while the estrogen level was significantly reduced in the NFAMF compared to the ControlF. LH, FSH, and PRL levels were significantly reduced in the NFAMF compared to the NFAMM. These findings further confirm that post-adolescent females are prone to breakfast skipping. The increase in testosterone levels and sperm count in the males establish that breakfast skipping might not interfere with the reproductive physiology in males as it does in females.

Abstract
Recently, it was demonstrated that the expression of BMAL1 was decreased in the endometrium of women suffering from recurrent spontaneous abortion. To investigate the pathological roles of uterine clock genes during pregnancy, we produced conditional deletion of uterine Bmal1 (cKO) mice and found that cKO mice could receive embryo implantation but not sustain pregnancy. Gene ontology analysis of microarray suggested that uterine NK (uNK) cell function was suppressed in cKO mice. Histological examination revealed the poor formation of maternal vascular spaces in the placenta. In contrast to WT mice, uNK cells in the spongiotrophoblast layer, where maternal uNK cells are directly in contact with fetal trophoblast, hardly expressed an immunosuppressive NK marker, CD161, in cKO mice. By progesterone supplementation, pregnancy could be sustained until the end of pregnancy in some cKO mice. Although this treatment did not improve the structural abnormalities of the placenta, it recruited CD161-positive NK cells into the spongiotrophoblast layer in cKO mice. These findings indicate that the uterine clock system may be critical for pregnancy maintenance after embryo implantation.

Abstract
Introduction: Normal and regular menstrual cycle is an important physiological function that indicates valuable information about women reproductive health, as well as the overall health. A lifestyle pattern could have influence on hormone activity and potential impact on menstrual regularity. Menstrual abnormalities are very common among adolescents. Aim: The aim of this study was to explore if the change of everyday habits, during pandemic, had an influence on hormone activity and menstrual regularity among young women. Material and methods: This study included 169 girls, from 15 to 25 years old, that were doing questionnaire based on menstruation characteristic and daily habits in period from December 2019 to October 2020. Average duration of menstrual cycle, before and during SARS-CoV-2 pandemic, was analyzed. Results: Average time of menarcha was age 12. During 2019, 17.2% of respondents had irregular menstrual cycle. Change of dietary habits, in the time of pandemic, was reported by 30% of girls and sleep habit by 35.5%. Additionally, 44% of them had less activities for school and 77% girls spent more time on their mobile phones. Conclusion: Analyzing data from menstrual history of examined girls, there was no statistically significant difference in menstrual cycle duration during pandemic, comparing it to previous period, despite the change of daily habits.

Abstract
OBJECTIVE The study was conducted to determine the prevalence of dysmenorrhea and investigate factors associated with dysmenorrhic pain among university students in Lahore, Pakistan. DESIGN AND SETTING A cross-sectional study was conducted across various public and private sector universities in Lahore. METHODS A self-administered structured questionnaire was used to collect data from 600 randomly selected female university students. RESULTS The prevalence of dysmenorrhea was 91.5%. Age at menarche (odds ratio [OR] = 1.96, 95% confidence interval [CI] = 1.10-3.50) was the only significant factor associated with dysmenorrhea. The mean pain severity score among dysmenorrhic students was 5.62 ± 2.28. Most of the participants (65.8%) were experiencing moderate/severe pain. Univariate analysis showed that irregular cycle (OR [95% CI] = 1.62 [1.13-2.33]), age at menarche of ≤14 years (OR [95% CI] = 1.46 [1.05-2.04]), duration of menses of more than 5 days (OR [95% CI] = 1.42 [1.02-1.99]), stress (OR [95% CI] = 2.16 [1.54-3.03]), moderate meat/protein consumption (OR [95% CI] = 1.55 [1.08-2.21]), and medical specialization (OR [95% CI] = 1.72 [1.17-2.52]) were significantly associated with pain severity among dysmenorrhic female students. Multivariate binary logistic regression analysis revealed that medical specialization (OR [95% CI] = 1.83 [1.22-2.73]), age at menarche (OR [95% CI] = 0.603 [0.42-0.86]), regularity of menses (OR [95% CI] = 1.52 [1.04-2.22]), moderate meat/protein consumption (OR [95% CI] = 1.69 [1.16-2.45]), and stress (OR [95% CI] = 1.87 [1.32-2.66]) were independent predictors of moderate/severe dysmenorrhic pain. CONCLUSION The study revealed an alarmingly high prevalence of dysmenorrhea among university students. High levels of stress and early menarche were the potent determinants of moderate/severe dysmenorrhea that disturbs quality of life.

Abstract
BACKGROUND Skipping breakfast is associated with dysmenorrhea in young women. This suggests that the delay of food intake in the active phase impairs uterine functions by interfering with circadian rhythms. OBJECTIVES To examine the relation between the delay of feeding and uterine circadian rhythms, we investigated the effects of the first meal occasion in the active phase on the uterine clock. METHODS Zeitgeber time (ZT) was defined as ZT0 (08:45) with lights on and ZT12 (20:45) with lights off. Young female mice (8 wk of age) were divided into 3 groups: group I (ad libitum consumption), group II (time-restricted feeding during ZT12-16, initial 4 h of the active period), and group III (time-restricted feeding during ZT20-24, last 4 h of the active period, a breakfast-skipping model). After 2 wk of dietary restriction, mice in each group were killed at 4-h intervals and the expression profiles of uterine clock genes, Bmal1 (brain and muscle aryl hydrocarbon receptor nuclear translocator-like protein 1), Per1 (period circadian clock 1), Per2, and Cry1 (cryptochrome 1), were examined. RESULTS qPCR and western blot analyses demonstrated synchronized circadian clock gene expression within the uterus. Immunohistochemical analysis confirmed that BMAL1 protein expression was synchronized among the endometrium and myometrium. In groups I and II, mRNA expression of Bmal1 was elevated after ZT12 at the start of the active phase. In contrast, Bmal1 expression was elevated just after ZT20 in group III, showing that the uterine clock rhythm had shifted 8 h backward. The changes in BMAL1 protein expression were confirmed by western blot analysis. CONCLUSIONS This study is the first to indicate that time-restricted feeding regulates a circadian rhythm of the uterine clock that is synchronized throughout the uterine body. These findings suggest that the uterine clock system is a new candidate to explain the etiology of breakfast skipping-induced uterine dysfunction.

Abstract
Objectives This study examined the influence of nutrition on the severity of menstrual pains and associated transient changes in blood pressure (BP) and vascular-health indicators. It has also investigated the influence of nutrition on angiotensin (ANG II) and vascular cell adhesion molecules (VCAM-1). Methods A total of 207 university students, aged between 18 and 25 years, were grouped into three groups: a no-dysmenorrhoea (control) group, a moderate dysmenorrhoea (MDys) group, and a severe dysmenorrhoea (SDys) group, using the NRS-11 scale and initial contactin-1 (CNTN-1) levels. The groups were separately fed vegetable, protein, and carbohydrate meals. The meal plan involved three different types of food served three times a day (for breakfast, lunch, and dinner), beginning 48 h before menstruation. Results We found that 73.9% and 100% of the MDys patients on the protein and carbohydrate diets, respectively, had severe dysmenorrhoea. As many as 69.6% of the SDys patients on vegetable diets experienced no dysmenorrhoea; the BP of 61% of SDys normalised to the standard values of 120/80. The BP of 87% MDys had systolic BP ≥ 130 and ≥90 diastolic BP after carbohydrate meals. On the other hand, 30% of SDys had higher BP after protein meals. With respect to the choice of food, the severity of menstrual pain was positively correlated with ANG II (r = 0.5158) and VCAM-1 (r = 0.5849). ANG-II. Similarly, VCAM-1 were significantly elevated (p < 0.05) in the dysmenorrhoeal participants. The mean VCAM-1 and ANG-II levels of dysmenorrhoeal participants placed on vegetable meals were comparable to the control baseline levels. Conclusions This study recommends the intake of a vegetable meal at least 48 h before menstruation as an effective nutritional approach to preventing and managing severe menstrual cramps. This approach can also prevent associated vascular changes. Carbohydrate meals should be avoided at least 48 h before menstruation.

Abstract
AIM Hypertensive disorders of pregnancy (HDP) are serious conditions that occur in 5-10% of pregnancies. Maternal factors, such as maternal age, obesity, and renal disease, have been described as risk factors. In order to extract the background lifestyle and gynecological characteristics for HDP, we conducted a prospective cohort study. METHODS Pregnant participants were administered a questionnaire on characteristics, menstrual abnormalities and lifestyle factors. The women were followed individually until 1-month postpartum. We used medical records to examine the relationship between menstrual abnormalities and the onset of HDP. RESULTS We collected data from 193 pregnant women, and excluding 3 who had miscarriage, examined the records of 190. A total of 26 patients developed HDP, of which 10 had early-onset HDP and 16 had late-onset HDP. Although there was no significant association between HDP and dysmenorrhea just prior to pregnancy, there was a significant increase in the incidence of HDP in patients who experienced dysmenorrhea around the age of 20 years (odds ratio 4.362 [95% CI 1.61-11.81]). CONCLUSION We found that patients with a history of dysmenorrhea around the age of 20 years have a significantly higher risk of developing HDP. Although dysmenorrhea in young adulthood is ameliorated, it may become apparent as a perinatal disease when a physical load such as pregnancy is applied.

Breakfast Skipping in Female College Students Is a Potential and Preventable Predictor of Gynecologic Disorders at Health Service Centers. Diagnostics (Basel) 2020; 10:diagnostics10070476. [PMID: 32668795 PMCID: PMC7400274 DOI: 10.3390/diagnostics10070476] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2020] [Revised: 07/03/2020] [Accepted: 07/06/2020] [Indexed: 11/23/2022] Open
Abstract
Inadequate dietary habits in youth are known to increase the risk of onset of various diseases in adulthood. Previously, we found that female college students who skipped breakfast had higher incidences of dysmenorrhea, suggesting that breakfast skipping interferes with ovarian and uterine functions. Since dietary habits can be managed by education, it is preferable to establish a convenient screening system for meal skipping that is associated with dysmenorrhea as part of routine services of health service centers. In this study, we recruited 3172 female students aged from 18 to 25 at Kanazawa University and carried out an annual survey of the status of students’ health and lifestyle in 2019, by a questionnaire. We obtained complete responses from 3110 students and analyzed the relationship between dietary habits, such as meal skipping and history of dieting, and menstrual disorders, such as troubles or worries with menstruation, menstrual irregularity, menstrual pain, and use of oral contraceptives. The incidence of troubles or worries with menstruation was significantly higher in those with breakfast skipping (p < 0.05) and a history of dieting (p < 0.001). This survey successfully confirmed the positive relationship between breakfast skipping and menstrual pain (p < 0.001), indicating that this simple screening test is suitable for picking up breakfast skippers who are more prone to gynecologic disorders. In conclusions, since dysmenorrhea is one of the important clinical signs, breakfast skipping may become an effective marker to predict the subsequent onset of gynecological diseases at health service centers. Considering educational correction of meal skipping, breakfast skipping is a potential and preventable predictor that will contribute to managing menstrual disorders from a preventive standpoint in the future.

Abstract
Diabetes mellitus is an important chronic disease causing economic and social burden. Insulin resistance is a determinant of diabetes, and regular eating patterns are an important factor in blood sugar control. This study investigated the association between breakfast frequency and the risk of increased insulin resistance in Koreans. Data for 12,856 participants without diabetes in the 2016–2018 Korea National Health and Nutrition Examination Survey were analyzed. Insulin resistance was assessed using the triglyceride-glucose (TyG) index, while the median TyG index value was used to define higher (≥8.5) vs. lower (<8.5) insulin resistance. Association between breakfast frequency and risk of increased insulin resistance was investigated using multiple logistic regression. Compared with those who had regular breakfast 5–7 times per week, the odds ratios (95% confidence intervals) of individuals who did not eat breakfast were the highest at 1.42 (95% CI = 1.24–1.64, p ≤ 0.0001). Those who had breakfast 1–4 times per week had an odds ratio of 1.17 (95% CI = 1.03–1.32, p = 0.0153). We found that a lower weekly breakfast consumption was associated with a higher risk of insulin resistance in Koreans. Promoting the benefits of breakfast can be an important message to improve the health of the population.

Abstract
There are growing concerns that poor dietary behaviors at young ages will increase the future risk of chronic diseases in adulthood. We found that female college students who skipped breakfast had higher incidences of dysmenorrhea and irregular menstruation, suggesting that meal skipping affects ovarian and uterine functions. Since dysmenorrhea is more prevalent in those with a past history of dieting, we proposed a novel concept that inadequate dietary habits in adolescence become a trigger for the subsequent development of organic gynecologic diseases. Since inadequate feeding that was limited during the non-active phase impaired reproductive functions in post-adolescent female rats, we hypothesize that circadian rhythm disorders due to breakfast skipping disrupts the hypothalamic–pituitary–ovarian axis, impairs the reproductive rhythm, and leads to ovarian and uterine dysfunction. To explain how reproductive dysfunction is memorized from adolescence to adulthood, we hypothesize that the peripheral clock system also plays a critical role in the latent progression of reproductive diseases together with the central system, and propose naming this concept “adolescent dietary habit-induced obstetric and gynecologic disease (ADHOGD)”. This theory will contribute to analyzing the etiologies of and developing prophylaxes for female reproductive diseases from novel aspects. In this article, we describe the precise outline of the above hypotheses with the supporting evidence in the literature.

Abstract
STUDY OBJECTIVE To examine prevalence and risk factors associated with primary dysmenorrhea among Chinese female university students in Hunan province, China. DESIGN A cross-sectional study. SETTING Female university students in Changsha city, Hunan province, China. PARTICIPANTS Four thousand six hundred six female individuals selected using a multistage cluster random sampling method. INTERVENTIONS A self-administered questionnaire, which included sociodemographic information, lifestyle habits, emotional characteristics, and menstruation pattern, was used to collect data. MAIN OUTCOME MEASURES Information about menarche, body mass index, cycle length and regularity, primary dysmenorrhea, physical exercise, depression, and anxiety. RESULTS The prevalence of primary dysmenorrhea was 41.7% (1921/4606) among Chinese female university students. Multivariate binary logistic regression indicated that being a minority (odds ratio [OR], 1.335; 95% confidence interval [CI], 1.083-1.646), underweight (OR, 1.249; 95% CI, 1.08-1.42), annual household income less than 80,000 CNY (OR, 1.169; 95% CI, 1.018-1.342), maternal history of dysmenorrhea (OR, 2.553; 95% CI, 2.236-2.915), age at menarche younger than 12 years (OR, 1.161; 95% CI, 1.013-1.329), irregular menstrual cycle (OR, 1.216; 95% CI, 1.063-1.391), and skipping breakfast (OR, 1.294; 95% CI, 1.124-1.490) were associated risk factors of primary dysmenorrhea. CONCLUSION The prevalence of primary dysmenorrhea among Chinese university students is relatively high. Various risk factors were identified that associated with primary dysmenorrhea. More effort and attention should therefore be directed toward this health problem in China.

Abstract
BACKGROUND We previously reported that skipping breakfast is associated with menstrual disorders of female college students during postadolescent maturation. OBJECTIVE In this study, we investigated the effects of meal timing during circadian cycle on the ovarian function using young female rats. METHODS Considering that rats are nocturnally active, 8-wk-old female Wistar rats were classified into 3 groups: fed during the daytime only (nonactive phase), night-time only (active phase), or control group I (without time or calorie restriction, free access to a standard caloric diet, 20.0% protein, 62.9% carbohydrate, and 7.0% fat, 3.95 kcal/g) for 4 wk. The changes in body weight and frequency of ovulation in each group were evaluated by a weight scale and a vaginal smear, respectively. At the end of the period of dietary restriction, ovaries were removed, and the numbers of growing follicles (mean diameter >250 µm) and corpora lutea (>600 µm) were examined using hematoxylin-eosin-stained tissue sections. In addition, 8-wk-old female rats were fed only during the night-time for 4 wk under a 20%-reduced food supply of the control group II (without any restriction). RESULTS In the daytime-fed group, the frequency and number of ovulations were significantly decreased compared with those in the control group I (P < 0.05), with a reduced body weight gain concomitant with about 20% of reduction in the daily food intake. In contrast, in the night-time-fed group, even when a 20% reduction in the daily food intake was loaded, their estrus cyclicity did not change despite significant reductions in weight gain and food intake compared with control group II. CONCLUSION These findings indicate that restricting food intake to the inactive phase impairs ovarian function in postadolescent female rats, suggesting that the timing of food intake during circadian cycle is one of the crucial factors interfering with the reproductive function.

MATERIALS AND METHODS In this study, cross-sectional questionnaires survey was conducted in different schools of Garhwal. These questionnaires were based on socioeconomic data, dietary and physical activities, and menstrual abnormalities. RESULTS The age of menarche was 13.5 ± 0.64 years. Dysmenorrhea (62.75%), premenstrual syndrome (PMS) (40.42%), and irregular cycle (28.72%) were observed common problems among adolescent girls. The result showed that dysmenorrhea, PMS, and menstrual irregularities were directly associated with dietary habits and physical activities. Dysmenorrhea was associated with eating junk food (66.10%), and PMS was associated with lacking of physical activities (78.94%). CONCLUSION The result suggests that feeding habit and physical activities directly affecting the menstrual health of adolescent girls.

Abstract
BACKGROUND The aim of this study was to investigate the relationship between lifestyle and overall health in high school children. METHODS Subjects were from the Toyama Birth Cohort Study, a prospective, longitudinal study of children born between 1989 and 1990, and who lived in Toyama Prefecture, Japan, at the time of the survey. This investigation used data from phase 5 of the Birth Cohort Study, which was conducted in 2005, when the children were in high school. Participants included 4,966 children (2,449 boys and 2,517 girls) aged 15-16 years old. A questionnaire was designed to measure lifestyle factors such as eating habits, physical activity, sedentary behavior, and sleeping pattern. A question from a validated Japanese version of the Dartmouth Primary Care Cooperative Information Project was used to evaluate overall health in children. Logistic regression analysis was used to determine if lifestyle factors are associated with overall health in high school children. RESULTS Boys who skipped breakfast and had short night-time sleep duration (≤6 h per night) were more likely to have poor health status. Girls who skipped breakfast, and had night-time eating patterns, personal computer use >4 h per day, and short night-time sleep duration (≤6 h/night) were more likely to have poor health status. CONCLUSIONS Undesirable lifestyle was associated with poor health status in high school boys and girls. Further understanding of these relationships is needed to facilitate the development of interventions that will help children with poor health status.

Abstract
BACKGROUND Few studies on gynaecological problems of young females in Arab countries were published. The aim of this study was to determine the prevalence of dysmenorrhea and predictors of its pain among university students in Palestine. METHODS A cross - sectional study was carried out on a randomly selected sample of An-Najah National University female students. A pre-designed questionnaire, which included questions regarding menstrual cycle, pain during menstruation, life style, nutritional habits, and symptoms associated with menstrual pain, was used. Pain intensity was measured using visual analogue scale. RESULTS A total of 956 female students were involved in the study. Of the total study sample, 846 (85.1%) reported having pain during menstruation; i.e. dysmenorrhea. Dysmenorrhea was significantly [(p = 0.027); OR = 1.5, 95% CI (1.05-2.19)] associated with age at menarche. The mean score of pain among dysmenorrhic females was 6.79 ± 2.64. The majority (654; 80.34%) of dysmenorrhic females reported having moderate/ severe pain. Univariate analysis using Chi-square test for factors associated with moderate/severe pain among dysmenorrhic females were irregular cycle [(p = 0.015); OR = 1.57, 95% CI = (1.09-2.30)], skipping breakfast [(p < 0.001); OR = 1.93, 95% CI = (1.33-2.79)], academic specialization [(p = 0.03; OR = 2.2, 95% CI = (1.21-3.98)] for medical specialization with reference to students in humanities), high stress level [(p = 0.036; OR = 1.53, 95% CI = (1.03-2.28)], and living in dormitories [(p = 0.034); OR = 1.72, 95% CI = (1.04-2.86)]. Multivariate analysis using binary logistic regression enter method showed that medical specialization [(p = 0.045); OR = 1.92, 95% CI = (1.02-3.64)] for medical students with reference to students in humanities), skipping breakfast [(p = 0.001); OR = 1.96, 95% CI = (1.35-2.86)], and irregular cycle [(p = 0.022); OR = 1.56, 95% CI = (1.07-2.29)] were the only significant predictors of moderate/severe dysmenorrhic pain. CONCLUSION There is a high proportion of dysmenorrhea among Palestinian female university students. Skipping breakfast was the strongest predictor for moderate/severe dysmenorrhea. Increased awareness regarding factors that might influence the intensity of dysmenorrhic pain is needed.

Abstract
BACKGROUND AND OBJECTIVES Breakfast skipping is prevalent among adolescents and young women, and deprives the body of important nutrients. This study was conducted to assess the correlation between breakfast eating and sociodemographic and lifestyle criteria. PARTICIPANTS AND METHODS A cross-sectional study was carried out on a convenient sample of 400 female students selected from the female sector of King Abdulaziz University, Jeddah, Saudi Arabia. Home breakfast habit and other lifestyle characteristics were studied using a standardized questionnaire. Logistic regression was used to examine the relationship between home breakfast habit and different predictors. RESULTS Home breakfast skippers constituted 71.75% of the whole sample. Breakfast eaters had a significantly higher BMI compared with breakfast skippers (22.66±4.88 vs. 21.58±4.09 in home breakfast skippers; P=0.025). Irrespective of other sociodemographic and lifestyle variables, fathers' education lower than university level negatively predicted home breakfast eating [Exp B=0.40, confidence interval (CI)=0.21-0.77], and being employed positively predicted breakfast eating (Exp B=2.31, CI=1.04-5.15). Likewise, consuming less amount of junk food and fewer soft drinks (Exp B=2.57, CI=1.54-4.28, and Exp B=2.59, CI=1.39-4.81, respectively) and consuming more milk and dairy products (Exp B=1.91, CI=1.16-3.15) correlated positively with home breakfast eating. CONCLUSION AND RECOMMENDATIONS Breakfast skipping was prevalent among adolescents and young women in the studied sample. Unhealthy dietary habits, father's education lower than university level, and father being unemployed positively predicted breakfast skipping of daughters at home. This implies that breakfast eating can be encouraged by approaching parents in addition to their daughters.

Abstract
Background: Primary dysmenorrhea seems to be one the most common gynecologic condition in women of childbearing age. Objectives: The aim of this research was to evaluate psychologic and nonpsychologic risk factors of primary dysmenorrhea. Materials and Methods: A cross-sectional study was conducted on medical sciences students of Babol University of Medical Sciences. In this study, 180 females with dysmenorrhea and 180 females without dysmenorrhea were enrolled. Psychological risk factors were evaluated in four domains including affect, social support, personality, and alexithymia. Four questionnaires were used to assessed aforementioned domains, namely, Social Support Questionnaire (SSQ), depression, anxiety, stress (DAS-21), 20-item Toronto Alexithymia Scale (TAS-20), and NEO-Five Factor Inventory of Personality (NEO-FFI). In addition, nonpsychologic factors were evaluated in three domains including demographic characteristics, habits, and gynecologic factors. Data were analyzed using the χ2 test and multiple logistic regression analysis. Results: The strongest predictor of primary dysmenorrhea was low social support (OR = 4.25; 95% CI, 2.43-7.41). Risk of dysmenorrhea was approximately 3.3 times higher in women with alexithymia (OR = 3.26; 95% CI, 1.88-5.62), 3.1 times higher in women with menstrual bleeding duration ≥ 7 days (OR = 3.06; 95% CI, 1.73-5.41), 2.5 times higher in women with a neurotic character (OR = 2.53; 95% CI, 1.42-4.50), 2.4 times higher in women with a family history of dysmenorrhea (OR = 2.43; 95% CI, 1.42-4.50), and twice higher in women with high caffeine intake (OR = 1.97; 95% CI, 1.09-3.59). Conclusions: Low social support, alexithymia, neuroticism trait, long menstrual bleeding, family history of dysmenorrhea, and high-caffeine diet are important risk factors for women with primary dysmenorrhea. This study recommended considering psychologic factors as an adjuvant to medical risks in evaluation and treatment of primary dysmenorrhea.

Abstract
Objectives Universal interventions may widen or narrow inequalities if disproportionately
effective among higher or lower socio-economic groups. The present paper examines
impacts of the Primary School Free Breakfast Initiative in Wales on inequalities in
children's dietary behaviours and cognitive functioning. Design Cluster-randomised controlled trial. Responses were linked to free school meal (FSM)
entitlement via the Secure Anonymised Information Linkage databank. Impacts on
inequalities were evaluated using weighted school-level regression models with
interaction terms for intervention × whole-school percentage FSM entitlement and
intervention × aggregated individual FSM entitlement. Individual-level regression models
included interaction terms for intervention × individual FSM entitlement. Setting Fifty-five intervention and fifty-six wait-list control primary schools. Subjects Approximately 4500 children completed measures of dietary behaviours and cognitive
tests at baseline and 12-month follow-up. Results School-level models indicated that children in intervention schools ate a greater
number of healthy items for breakfast than children in control schools
(b = 0·25; 95 % CI 0·07, 0·44), with larger increases observed in more
deprived schools (interaction term b = 1·76; 95 % CI 0·36, 3·16). An
interaction between intervention and household-level deprivation was not significant.
Despite no main effects on breakfast skipping, a significant interaction was observed,
indicating declines in breakfast skipping in more deprived schools (interaction term
b = −0·07; 95 % CI −0·15, −0·00) and households (OR = 0·67; 95 % CI
0·46, 0·98). No significant influence on inequality was observed for the remaining
outcomes. Conclusions Universal breakfast provision may reduce socio-economic inequalities in consumption of
healthy breakfast items and breakfast skipping. There was no evidence of
intervention-generated inequalities in any outcomes.

Effect of skipping breakfast on subsequent energy intake. Physiol Behav 2013; 119:9-16.

Abstract
The objective was to examine the effect of consuming breakfast on subsequent energy intake. Participants who habitually ate breakfast and those who skipped breakfast were recruited for two studies. Using a randomized crossover design, the first study examined the effect of having participants consume either (a) no breakfast, (b) a high carbohydrate breakfast (335 kcals), or (c) a high fiber breakfast (360 kcals) on three occasions and measured ad libitum intake at lunch. The second study again used a randomized crossover design but with a larger, normal carbohydrate breakfast consumed ad libtum. Intake averaged 624 kcals and subsequent food intake was measured throughout the day. Participants ate only foods served from the Cornell Human Metabolic Research Unit where all foods were weighed before and after consumption. In the first study, neither eating breakfast nor the kind of breakfast consumed had an effect on the amount consumed at lunch despite a reduction in hunger ratings. In the second study, intake at lunch as well as hunger ratings were significantly increased after skipping breakfast (by 144 kcal), leaving a net caloric deficit of 408 kcal by the end of the day. These data are consistent with published literature demonstrating that skipping a meal does not result in accurate energy compensation at subsequent meals and suggests that skipping breakfast may be an effective means to reduce daily energy intake in some adults.

Abstract
OBJECTIVES To prepare a dietary recommendation for young Japanese for the prevention of coronary heart disease, we surveyed the dietary habits, serum lipids, serum fatty acids and blood pressure levels among male and female students. METHODS In this study, 175 male and 246 female university students were interviewed for the frequency of consumption of selected food items and the habit of skipping breakfast. Serum fatty acids were analyzed by gas chromatography. RESULTS The frequencies of consumption of dishes cooked with oil and intake of vegetables were higher in female students than in male students. Serum n-6 polyunsaturated fatty acids were slightly higher in females students than in male students while that of serum n-3 polyunsaturated fatty acids was 6.4% in both sexes. For both males and females, those who skipped breakfast at least once a week were less likely to consume vegetables and fruits than those who did not. Female students who skipped breakfast were also less likely to consume fish and had lower composition of n-3 polyunsaturated fatty acid and higher systolic and diastolic blood pressure levels than males. For female, the intake of milk and dairy products correlated inversely with systolic blood pressure levels and the intake of n-3 polyunsaturated fatty acids correlated inversely with diastolic blood pressure levels. For males, the intake of fruits and consumption of dishes cooked with oil correlated inversely with systolic and diastolic blood pressure levels. CONCLUSION Our findings suggest that increased intake of fish, milk and dairy products, fruits and vegetables from early adulthood and a regular dietary pattern are important to reduce the risk factors for coronary heart disease.

Abstract
AbstractObjectiveThe present study evaluated the impact of a national school programme of universal free healthy breakfast provision in Wales, UK.DesignA cluster randomised controlled trial with repeated cross-sectional design and a 12-month follow-up. Primary outcomes were breakfast skipping, breakfast diet and episodic memory. Secondary outcomes were frequency of eating breakfast at home and at school, breakfast attitudes, rest-of-day diet and class behaviour.SettingPrimary schools in nine local education authority areas.SubjectsA total of 4350 students (aged 9–11 years) at baseline and 4472 at follow-up in 111 schools.ResultsStudents in intervention schools reported significantly higher numbers of healthy food items consumed at breakfast and more positive attitudes towards breakfast eating at 12 months. Parents in intervention schools reported significantly higher rates of consumption of breakfast at school and correspondingly lower rates of breakfast consumption at home. No other significant differences were found.ConclusionsThe intervention did not reduce breakfast skipping; rather, pupils substituted breakfast at home for breakfast at school. However, there were improvements in children’s nutritional intake at breakfast time, if not the rest of the day, and more positive attitudes to breakfast, which may have implications for life-course dietary behaviours. There was no impact on episodic memory or classroom behaviour, which may require targeting breakfast skippers.

Abstract
Many studies have found an association between breakfast skipping and either body mass index (BMI; calculated as kg/m(2)) or overweight/obesity among adolescents, but several studies have found no association. This cross-sectional study investigated the hypothesis that this discrepancy is partly due to three differences in methodology. First, some studies have examined BMI, but other studies have examined overweight/obesity. Second, some studies have controlled for potential confounders, but other studies have not. Third, different studies have used different definitions of breakfast skipping. This study examined both the relationship between breakfast skipping and BMI and the relationship between breakfast skipping and overweight/obesity, compared unadjusted results with results adjusted for potential confounders, and compared results for 24 definitions of breakfast skipping. The sample consisted of 811 students at high schools in Piraeus, Greece, who completed a questionnaire and had their height and weight measured. The results supported this hypothesis. First, fewer breakfast-skipping variables were associated with BMI than with overweight/obesity. Second, fewer associations were found when controlling than when not controlling for potential confounders. Third, fewer associations were found for variables corresponding to some definitions of breakfast skipping than for variables corresponding to other definitions.

Abstract
Recently many young women in Japan have been restricting their dietary intake for cosmetic purposes. In this study, the relation between diet and menstrual disorders was investigated by responses to a questionnaire. Subjects ranging from 18 to 20 years old were recruited from 716 female students at Ashiya College. Dietary habits were classified into group I (having no experience with dieting), group II (those currently on a diet) and group III (those with a history of dieting). The intensity of dysmenorrhea was classified into three grades. All participants were divided into two groups as having regular or irregular menstruation. The frequency of irregular menstruation in group II was higher than that in the other groups, while group III had higher intensity of dysmenorrhea than the other groups. These findings suggest that diet during adolescence has long-lasting adverse effects on reproductive function in young women.

Abstract
In this study, to estimate the current status of young women with menstrual disorders, the relation among dysmenorrhea, irregular menstruation and premenstrual symptoms was investigated by a questionnaire. Subjects ranging from 18 to 20 years old were recruited from 522 female students at Ashiya College in Japan. The intensity of dysmenorrhea was classified into 3 grades (score 1, not requiring analgesic; score 2, painful, requiring analgesic; score 3, painful, not relieved by analgesic). All participants were further divided into subsequent groups as having premenstrual symptoms or not and those having regular or irregular menstruation. Dysmenorrhea scores in the students with premenstrual symptoms or irregular menstruation were significantly higher than those without these symptoms (1.66±0.66 vs 1.41±0.59; 1.62±0.68 vs 1.49±0.61, respectively). There was no significant relation in the incidence between premenstrual symptoms and irregular menstruation. These findings suggest that considerable numbers of young women with dysmenorrhea are associated with premenstrual symptoms.

Abstract
Background School-based breakfast provision is increasingly being seen as a means of improving educational performance and dietary behaviour amongst children. Furthermore, recognition is growing that breakfast provision offers potential as a means of addressing social inequalities in these outcomes. At present however, the evidence base on the effectiveness of breakfast provision in bringing about these improvements is limited. Methods/Design This paper describes the research design of a large scale evaluation of the effectiveness of the Welsh Assembly Government's Primary School Free Breakfast Initiative. A cluster randomised trial, with school as the unit of randomisation was used for the outcome evaluation, with a nested qualitative process evaluation. Quantitative outcome measures included dietary habits, attitudes, cognitive function, classroom behaviour, and school attendance. The study recruited 111 primary schools in Wales, of which 56 were randomly assigned to control condition and 55 to intervention. Participants were Year 5 and 6 students (aged 9–11 years) in these schools. Data were collected for all 111 schools at each of three time points: baseline, 4 month and 12 month follow-up. This was achieved through a repeated cross-sectional survey of approximately 4350 students on each of these occasions. Of those students in Year 5 at baseline, 1975 provided data at one or both of the follow-ups, forming a nested cohort. The evaluation also included a nested process evaluation, using questionnaires, semi-structured interviews and case studies with students, school staff, and local authority scheme coordinators as key informants. Discussion An overview of the methods used for the evaluation is presented, providing an example of the feasibility of conducting robust evaluations of policy initiatives using a randomised trial design with nested process evaluation. Details are provided of response rates and the flow of participants. Reflection is offered on methodological issues encountered at various stages through the course of the study, focusing upon issues associated with conducting a randomised trial of a government policy initiative, and with conducting research in school settings.

Abstract
AbstractObjectivesTo examine school-level relationships between deprivation and breakfast eating behaviours (breakfast skipping and the healthfulness of foods consumed) in 9–11-year-old schoolchildren and to examine whether attitudes towards eating breakfast mediated these relationships.DesignCross-sectional survey.SettingOne hundred and eleven primary schools in Wales.SubjectsYear 5 and 6 pupils within the 111 primary schools. Measures were completed by 4314 children. Analysis was conducted at the group (school) level, with each school representing one group.ResultsDeprivation was positively associated with breakfast skipping and consumption of ‘unhealthy’ items (i.e. sweet snacks, crisps) for breakfast. A significant negative association was found between deprivation and consumption of ‘healthy’ items (i.e. fruit, bread, cereal, milk). Deprivation was significantly inversely associated with attitudes towards eating breakfast. The relationships between deprivation and (1) breakfast skipping and (2) consumption of ‘healthy’ items for breakfast were mediated by attitudes towards eating breakfast. The hypothesis that attitudes mediated the relationship between deprivation and consumption of ‘unhealthy’ breakfast items was unsupported.ConclusionsDeprivation is associated with adverse breakfast eating behaviours amongst children aged 9–11 years, in terms of breakfast skipping and the quality of breakfasts consumed. Socio-economic differences in attitudes towards eating breakfast are apparent amongst this age group, and appear to relate to social gradients in breakfast eating behaviours. Research is needed to examine the causal nature of these trends and to elucidate factors underlying the development of socio-economic differences in eating-related cognitions.

Abstract
The objective of this study is to assess the literature concerning the effect of diet on endometriosis and dysmenorrhea and to elucidate evidential support, to give dietary recommendations to women suffering from these conditions. A systematic search in electronic databases on a relationship between diet and endometriosis/dysmenorrhea was performed. Data on diet and endometriosis were limited to four trials of which two were animal studies. The articles concerning human consumption found some relation between disease and low intake of vegetable and fruit and high intake of vegetarian polyunsaturated fat, ham, beef and other red meat. Results concerning fish intake were not consistent. Eight trials of different design, with a total of 1097 women, investigated the relationship between diet and dysmenorrhea. Intake of fish oil seemed to have a positive effect on pain symptoms. This study concludes that literature on diet and endometriosis is sparse, whereas eight studies have looked at diet and dysmenorrhea. No clear recommendations on what diet to eat or refrain from to reduce the symptoms of endometriosis can be given, while a few studies indicate that fish oil can reduce dysmenorrhea. Further research is recommended on both subjects.

Abstract
Background Regular breakfast eating (RBE) is an important contributor to a healthy lifestyle and health status. The aims of the present study were to evaluate the relationships among irregular breakfast eating (IRBE), health status, and health promoting behavior (HPB) for Taiwanese adolescents. Methods A cross-sectional, descriptive design was used to investigate a cluster sample of 1609 (7th -12th grade) adolescents located in the metropolitan Tao-Yuan area during the 2005 academic year. The main variables comprised breakfast eating pattern, body weight, and health promoting behaviors. Data were collected by a self-administered questionnaire. Results A total of 1609 participants were studied, 64.1% in junior high school and 35.9% in high school, boys (47.1%) and girls (52.9%) ranging in age from 12–20 years. Of the total participant population, 28.8% were overweight and nearly one quarter (23.6%) reported eating breakfast irregularly during schooldays. The findings indicated that adolescents with RBE had a lower risk of overweight (OR for IRBE vs. RBE = 1.51, 95% CI: 1.12, 2.04), and that the odds of becoming overweight were 51% greater for IRBE than for RBE even after controlling for demographical and HPB variables. IRBE also was a strong indicator for HPB. However, the profile of the high-risk IRBE group was predominantly junior high schoolchildren and/or children living without both parents. Conclusion This study provides valuable information about irregular breakfast eating among adolescents, which is associated with being overweight and with a low frequency of health promoting behavior. School and family health promotion strategies should be used to encourage all adolescents to eat breakfast regularly.

Abstract
OBJECTIVE To evaluate the validity and reliability of a dietary recall questionnaire, designed for group-level comparisons of foods eaten at breakfast and intake of fruits, vegetables, sweet items and crisps. DESIGN Validity was assessed relative to 24-h dietary recall interviews, and reliability by comparing the baseline data with 4-month follow-up data. SUBJECTS AND SETTING Fifty-eight schools took part in the validity assessments, with 374 children completing both measures. Reliability was assessed using 29 schools, with 1233 children at baseline and 1033 at follow-up. Children were aged 9-11 years and schools were located in socio-economically deprived areas of Wales. RESULTS Results indicated moderate to substantial agreements for most foods eaten at breakfast on the day of reporting and fair to moderate agreements for breakfast foods the previous day. For items throughout the rest of the previous day, agreement was fair to substantial during school hours, but slight after school. Correlations were moderate in terms of 'healthy' items and 'unhealthy' items consumed at breakfast on the day of reporting, but weaker for the previous breakfast. Correlations between measures in terms of fruits, vegetables, sweet items and crisps throughout the rest of the previous day were fair to moderate. The measure demonstrated fair to substantial group-level reliability. CONCLUSIONS The questionnaire, while subject to a number of limitations, gives an adequately valid and reliable overview of selected aspects of children's diet. It is likely to be of value at group-level in randomized controlled trials of school-based interventions.

Abstract
OBJECTIVE Information on modifiable lifestyle factors associated with constipation is limited, especially among non-Western populations. We examined associations between dietary intake and self-reported constipation in young Japanese women. DESIGN Cross-sectional study. SUBJECTS A total of 1,705 female Japanese dietetic students aged 18-20 years and free of current disease and current dietary counseling. METHODS Dietary intake was estimated over a 1-month period with a validated, self-administered, diet history questionnaire, and lifestyle variables including self-reported constipation were assessed by a second questionnaire designed for this survey. RESULTS A total of 436 women (26%) reported themselves to be 'constipated'. A multivariate odds ratio (OR) for women in the highest quartile of rice intake was 0.47 (95% confidence interval (CI): 0.33, 0.68) compared with the lowest. Additionally, women in the highest category of coffee intake had a multivariate OR of 0.67 (0.47, 0.94) compared with women in the lowest. Conversely, women in the highest quartile of confectionery intake had a multivariate OR of 1.54 (1.12, 2.13) compared with women in the lowest. Moreover, a multivariate OR for constipation for women in the highest quartile of Japanese and Chinese tea intake was 1.49 (1.09, 2.05) compared with women in the lowest. Neither total dietary fiber intake nor other lifestyle factors examined were associated with constipation. CONCLUSIONS The consumption of rice and coffee was inversely associated with and that of confectioneries and Japanese and Chinese tea was positively associated with a prevalence of self-reported constipation.

Abstract
Breakfast has been labeled the most important meal of the day, but are there data to support this claim? We summarized the results of 47 studies examining the association of breakfast consumption with nutritional adequacy (nine studies), body weight (16 studies), and academic performance (22 studies) in children and adolescents. Breakfast skipping is highly prevalent in the United States and Europe (10% to 30%), depending on age group, population, and definition. Although the quality of breakfast was variable within and between studies, children who reported eating breakfast on a consistent basis tended to have superior nutritional profiles than their breakfast-skipping peers. Breakfast eaters generally consumed more daily calories yet were less likely to be overweight, although not all studies associated breakfast skipping with overweight. Evidence suggests that breakfast consumption may improve cognitive function related to memory, test grades, and school attendance. Breakfast as part of a healthful diet and lifestyle can positively impact children's health and well-being. Parents should be encouraged to provide breakfast for their children or explore the availability of a school breakfast program. We advocate consumption of a healthful breakfast on a daily basis consisting of a variety of foods, especially high-fiber and nutrient-rich whole grains, fruits, and dairy products.

Abstract
Accumulating evidence suggests that food customs are associated with quality of life in women of the reproductive age. In Japan, dietary limitation for cosmetic purposes, skipping food intake, intake of processed foods and the shift from Japanese to Westernized style food have increased among young women. These changes in food habits can cause inadequate intake of calories, micronutrients, unsaturated fat, phytestrogens and fiber as well as increasing environmental toxins. Furthermore, these food habits increase risk as a result of intake of food additives, anti-oxidants, processing agents and sweeteners, which have been demonstrated to be harmful to human health. These factors are speculated to not only influence the present lifestyle, but also to induce gynecologic disorders such as dysmenorrhea and irregular menstruation. The adverse effects of these dietary habits on pregnancy outcome and carcinogenesis of breast and ovarian cancers have also been demonstrated. In addition, latent development of organic diseases such as endometriosis, which are accompanied by dysmenorrhea, is a concern under the current nutritional environment in young women. Thus, it is an urgent issue to evaluate the present situation of eating habits in young Japanese women and estimate the influence of these habits on the quality of life including reproductive functions.
