Although functional gastrointestinal disorders (FGIDs) are very common in pediatric patients, there is a scarcity of published epidemiologic data, characteristics, and management patterns from Saudi Arabia, which is the 2nd largest Arabic country in terms of area and the 6th largest Arabic country in terms of population, with 10% of its population aged <5 years. Functional constipation (FC) is an FGID that has shown a rising prevalence among Saudi infants and children in the last few years, which urges us to update our clinical practices. Nine pediatric consultants attended two advisory board meetings to discuss and address current challenges, provide solutions, and reach a Saudi national consensus for the management of pediatric constipation. The pediatric consultants agreed that pediatricians should pay attention to any alarming signs (red flags) found during history taking or physical examinations. They also agreed that the Rome IV criteria are the gold standard for the diagnosis of pediatric FC. Different therapeutic options are available for pediatric patients with FC. Dietary treatment is recommended for infants with constipation for up to six months of age. When non-pharmacological interventions fail to improve FC symptoms, pharmacological treatment with laxatives is indicated. First, the treatment is aimed at disimpaction to remove fecal masses. This is achieved by administering a high dose of oral polyethylene glycol (PEG) or lactulose for a few days. Subsequently, maintenance therapy with PEG should be initiated to prevent the re-accumulation of feces. In addition to PEG, several other options may be used, such as Mg-rich formulas or stimulant laxatives. However, rectal enemas and suppositories are usually reserved for cases that require acute pain relief. In contrast, infant formulas that contain prebiotics or probiotics have not been shown to be effective in infant constipation, while the use of partially hydrolyzed formula is inconclusive. These clinical practice recommendations are intended to be adopted by pediatricians and primary care physicians across Saudi Arabia.

Objective: Due to current selection practices for increased egg production and peak persistency, the production profile, age at maturity, and body weight criteria for commercial layers are constantly changing. Body weight and age at the time of photostimulation will thus always be the factors that need to be adequately addressed among various production systems. The current study was carried out to determine the effects of pullets' body weight (low, medium, and heavy) on their performance, welfare, physiological response, and hormonal profile. Methods: With regard to live weight, 150 16-week-old pullets were divided into three groups using a completely randomized design (CRD) and held until the 50th week. One-way analysis of variance was used to evaluate the data under the CRD, and the least significant difference test was used to distinguish between treatment means. Results: In comparison to the medium and light birds, the heavy birds had higher body weight at maturity, an earlier age at maturity, and higher egg weight, eggshell weight, eggshell thickness, egg yolk index, breaking strength, egg surface area, egg shape index, egg volume, and hormonal profile except corticosterone. However, the medium and light birds had lower feed consumption rates per dozen eggs and per kilogram of egg mass than the heavy birds. Light birds showed greater body weight gain, egg production, and egg specific gravity than the other categories. At 20 weeks of age, physiological response, welfare aspects, and catalase were non-significant; however, at 50 weeks of age, all these factors-aside from catalase-were extremely significant. Conclusion: The findings of this study indicate that layers can function at lower body weights during photostimulation; hence, dietary regimens that result in lighter pullets may be preferable. Additionally, the welfare of the birds was not compromised by the lighter weight group.

In this study, we examined family history of chronic diseases, food group intake and physical activity in $5^{th}\;and\; 6^{th}$ grade elementary school children. Food group intake was compared with the KDRI food guides for children. The measurements of daily physical activity, television viewing, computer use, and daily servings of five food groups, including grains, meats, dairy products, fruits, and vegetables, were based on child and parent self-reports. As indices of obesity, the obesity index(%) and BMI(Body Mass Index) were used. The results were as follows. In boys, 83.2% were normal weight with 7.4% slightly obese, 7.4% moderately obese, and 2.0 were highly obese while the percentages of normal and slightly obese in girls were 89.9% and 6.2% respectively (p<0.05). The boys had more hours of daily physical activity(p<0.05) and more hours of computer usage(Internet searching or games)(p<0.05) than the girls. Slightly over 50% of the subjects met the daily recommended servings of grains, dairy products, fruits, and vegetables according to the KDRI food guides. However, only 26% of boys and 27% of girls met the recommended daily servings of protein foods such as meats, beans, and eggs. Thirty two percent(32%) of girls consumed high fat snacks everyday while 32% consumed high sugar snacks every day. The girls consumed more vegetables(p<0.05) and more high sugar snacks(p<0.05) than the boys. The children with family histories of obesity showed greater obesity rates(p<0.05) and sedentary lifestyles(p< 0.05) than those children without a family history of obesity. Children with family histories of high blood pressure consumed more sewings of vegetables and high fat snacks than the controls(p<0.05). The children with family histories of obesity consumed more high sugar or high fat snacks than the controls(p<0.05).

Purpose: This study was conducted to examine the prevalence of food allergy, food allergy knowledge, and perception on food allergen labelling along with management of substitute meals in school foodservice in elementary school students in Jeju, South Korea. Methods: Six elementary schools in Jeju-si were randomly selected, and the higher grade elementary school students (n=1,500), from fourth graders to sixth graders, were surveyed using a questionnaire in July 2014. A total of 1,000 responses were used for data analysis. Results: The percentage of students who had experienced food allergy was 16.7%; 26.4% had been diagnosed as having a food allergy by doctors. Milk, crabs, and shrimps were the most frequent allergenic foods with common symptoms including urticaria followed by itching, and vomiting. As the student's grade went up, the knowledge scores on food allergy showed a significant increase. Although students with and without food allergy experience had a similar level of knowledge on food allergy and perception on food allergen labelling, students with food allergy experience had a significantly lower level of healthy dietary practices. Last, only 20.4% of students with food allergies were offered substitute meals by school foodservices, and 30.8% of students received food allergy education. Conclusion: For prevention and management of food allergies in school foodservice, schools should provide an individualized substitute meal plan and food allergy education to students, parents, and teachers.

The purpose of this study was to develop a workbook that can support the class and evaluation of the subject, 「Food safety and health」 and to verify its validity. The development direction of the workbook was set by analyzing the 「Food safety and health」 curriculum, dietary education materials, and previous studies related to the workbook, and the overall structure was designed by deriving the activity ideas for each area. Based on this, the draft was developed, and the draft went through several rounds of cross-review by the authors and the examination and revision by the Ministry of Food and Drug Safety, before the final edited version was developed. The workbook was finalized with corrections and enhancements based on the advice of 9 experts and 44 home economics teachers. The workbook consists of 4 areas: the 'food selection' area, with 10 learning topics and 36 lessons, the 'food poisoning and food management' area, with 10 learning topics and 36 lessons, the 'cooking' area, with 11 learning topics and 43 lessons, and the 'healthy eating' area, with 11 learning topics and 55 lessons, resulting in a total of 42 learning topics, 170 lessons. The workbook was designed to evenly cultivate practical problem-solving competency, self-reliance capacity, creative thinking capacity, and community capacity. In-depth inquiry-learning is conducted on the content, and the context is structured so that self-diagnosis can be made through evaluation. According to the validity test of the workbook, it was evaluated to be very appropriate for encouraging student-participatory classes and evaluations, and to create a class atmosphere that promotes inquiry by strengthening experiments and practices. In the current situation where the high school credit system is implemented and individual students' learning options are emphasized, the results of this study is expected to help expand the scope of home economics-based elective courses and contribute to realizing student-led classrooms with a focus on inquiry.
