Background and Objectives
To study associations in diet quality academic performance and weight status in urban adolescent high-school students.
Materials and MethodsThis study was a cross-sectional study in high schools in Tehran, Iran. A total of 629 students (317 boys and 309 girls), aging 17–19 years, from 49 high schools participated in the study. Dietary intake was measured using two 24-h recalls. Diet quality was measured using Healthy Eating Index-2015. Academic performance was assessed by evaluating scores achieved in national exams at the end of high-school junior year. Standard anthropometric measurements were used. Linear and multinomial regressions were used to assess the associations between weight status, diet quality and academic performance.
ResultsStudent’s scores in grammar and literature were significantly associated to diet quality (p < 0.05). After adjusting for sex and other socioeconomic confounders, the association was non-significant. Significant differences were seen in weight status between boys and girls; however, such differences were not based on the prosperity levels in weight statuses. The overall frequency of overweight was nearly 24%, while obesity was twice in boys (nearly 26%), compared to girls.
ConclusionsFindings verify needs of policies to improve student diet quality, leading to better health and educational achievements. Further studies are needed to investigate associations between diet quality and academic performance.

BackgroundObesity in school-aged children has become a major public health concern.ObjectivesThis study aimed to investigate the relationship between weight status, dietary behavior and diet diversity in 10 to 12- year-old students in the city of Tehran.MethodsThe sample included 487 students (51.8% girls) aged 10 - 12 years.Weight, height as well as age- and sex-specific BMI z-scores were determined. Demographics (sex, age, birth order and parental age) and socioeconomic characteristics (family size, parents’ educational level, occupation, ethnicity and housing status) were assessed by a questionnaire. Dietary intake was assessed through interview using 3-day 24-hours dietary recalls.ResultsBased on the BMI z-scores of the children, 1.9%, 47.9%, 27.2% and 22.8% were thin, normal, overweight and obese, respectively. In boys, mother’s educational level; and among girls, being at post-menarche stage and paternal job position were significantly associated with their weight status (P = 0.08, P = 0.05, P = 0.05, respectively). Boys in the lowest tertile for energy intake were at lower risk of obesity (OR = 0.04; 95% CI: 0.02 - 0.97) and those in the middle tertile of grains diversity score had a greater risk of obesity (OR = 5.84; 95% CI: 1.29 - 26.42) in comparison with those in the highest tertile. In girls, those in the lowest tertile of dairy diversity had higher risk of overweight compared to those in the highest tertile (OR = 9.77; 95% CI: 1.60 - 58.57).ConclusionsFindings indicate that energy intake and dietary diversity can affect the risk of overweight and obesity in preadolescents. Further studies are required to explore a more generalizable relationship between dietary intake and weight.Keywords: Children, Obesity, Weight Status, Dietary Diversity Score, Dietary Intake

Backgroundconsidering the increasing incidence of overweightness and obesity along with underweight among children, the investigation of the association between weight status and dietary pattern could provide valuable information about health of children. The aim of the present study was to assess the association between dietary pattern and weight status of rural school-aged children in Bijar County, Iran.MethodsThis cross-sectional study consisted of 255 rural school-aged children (aged 7 to 12 years) from Bijar county that were selected through simple random sampling. Dietary data were obtained by a semi-quantitative food frequency questionnaire. Also, assessment of anthropometric indices, physical activity, and demographic information was performed using standard procedures. Major dietary patterns were determined through the use of principal components analysis, and their association with child weight status was also investigated.ResultsThree dietary patterns, including traditional, modern, and mixed were identified. After adjustment based on age, physical activity, and energy intakes, P trend was significant and showed an upward trend for the chances of being overweight and obese in the quartile of the traditional dietary pattern (p for trend = 0.04). The risk of thinness and severe thinness significantly increased when "modern" dietary pattern was greatly followed (p for trend = 0.04).ConclusionsModern and mixed dietary patterns next to the traditional dietary pattern could be found among rural children. The current findings show that the traditional dietary pattern is associated with an increased risk of obesity; however, the modern dietary pattern leads to thinness in rural areas.Keywords: Children, Dietary Pattern, Rural, Weight Status

سابقه و هدفبا توجه به شیوع رو به افزایش اضافه وزن و چاقی در میان کودکان روستایی علی رغم بالا بودن شیوع کم وزنی، شناسایی الگوهای غذایی غالب و بررسی ارتباط آن با وضعیت وزن می تواند اطلاعات مفیدی را در مورد وضعیت سلامتی کودکان در اختیار قرار دهد. هدف از این مطالعه، تعیین الگوهای غذایی غالب و ارتباط آن با وضعیت وزنی کودکان روستایی سنین دبستان در شهرستان بیجار بود.مواد و روش هادر این مطالعه مقطعی 255 کودک روستایی سنین دبستان ساکن شهرستان بیجار به روش نمونه گیری تصادفی ساده انتخاب شدند. دریافت های غذایی در طول یک سال گذشته به وسیله پرسشنامه بسامد خوراک نیمه کمی مورد بررسی قرار گرفت. همچنین ارزیابی شاخص های تن سنجی (وزن، قد و نمایه توده بدنی)، فعالیت بدنی، اطلاعات عمومی و اقتصادی- اجتماعی به روش استاندارد انجام شد. الگوهای غذایی غالب به روش تحلیل عاملی تعیین گردید و ارتباط آنها با وضعیت وزنی کودکان مورد بررسی قرار گرفت.یافته هاسه الگوی غذایی سنتی، امروزی و مخلوط شناسایی شد. ارتباط معناداری بین الگوهای غذایی شناسایی شده و اضافه وزن یا چاقی پس از تعدیل اثر سن، فعالیت بدنی و انرژی دریافتی مشاهده نشد. در بالاترین چارک الگوی غذایی « سنتی» ، بعد از تعدیل بر اساس سن و فعالیت بدنی، شانس اضافه وزن و چاقی به طور معنی داری بیشتر بود (OR : 33/4 ، محدوده اطمینان 95 % :46/16 14/1) که بعد از تعدیل برای انرژی دریافتی معنی داری از بین رفت. روند شانس لاغری و لاغری شدید بعد از تعدیل برای سن، فعالیت بدنی و انرژی دریافتی با پیروی بیشتر از الگوی غذایی «امروزی» به طور معنی داری افزایش بود ( 04/0=p for trend).نتیجه گیریدر میان کودکان روستایی الگوی غذایی امروزی و مخلوط در کنار الگوی غذایی سنتی قابل شناسایی است که با پیروی بیشتر از الگوی غذایی سنتی شانس اضافه وزن و چاقی افزایش می یابد که این افزایش احتمالا به دلیل دریافت انرژی بالاتر در پیروی بیشتر از این الگو است. پیروی بیشتر از الگوی غذایی امروزی می تواند لاغری را به همراه داشته باشد.کلید واژگان: الگوی غذایی, روستا, کودکان, وضعیت وزنBackground And ObjectivesDue to the increasing incidence of overweight and obesity among rural children, despite the high prevalence of underweight, identification of dietary patterns and their association with weight status can provide valuable information about health of children. This study was conducted to detect major dietary patterns and their relationship with weight status in school age children in rural areas of Bijar, IranMaterials And MethodsIn this cross-sectional study, 255 rural school age children living in the rural areas of Bijar were selected by simple random sampling. Dietary intakes during the past year were examined by a semi-quantitative food frequency questionnaire. Assessment of anthropometric indicators, physical activity, and socioeconomic information was performed by standard methods. Dietary patterns were determined using factor analysis, and their relation to weight status of children was investigated.ResultsThree major dietary patterns, "traditional", "modern" and "mixed" were identified. There was no significant adjusted relationship between overweight or obese and identified dietary patterns. After adjustment for age and physical activity, individuals in the highest quartile of the traditional dietary pattern score were more likely to be overweight or obese (OR = 4.33, CI 95%: 1.14 -16.46). More adherence to modern dietary pattern resulted in a significant increase in the odds ratio of severe thinness and thinness (P for trend = 0.04).ConclusionModern and mixed dietary patterns next to the traditional dietary pattern can be found among rural children. While following the traditional dietary pattern probably due to higher energy is associated with an increased risk of obesity, modern dietary pattern leads to thinness in rural areas.Keywords: Dietary pattern, Rural, Children, Weight status

Healthy eating and physical activity habits formed during childhood can persist into adulthood and prevent or delay premature onset of a number of chronic diseases. The aim of this study was patterns of physical activity and dietary habit in relation to weight status in adolescent girls. In a cross sectional study, using two stage cluster sampling 256 adolescent girls were randomly selected from 8 Semnan secondary schools. Weigh and height were measured and Body Mass Index (BMI) was calculated. In adolescents, anthropometric indices were defined based on the CDC 2000 cut-off points for age and gender-specific BMI. Data of energy and nutrient intake was collected with the 24-hour dietary recall and food record questionnaires. The food frequency questionnaire was used to evaluate daily food consumption. Physical activity was determined using Baecke questionnaire. Data analyzed indicated that daily fat intake (p=0.003, r=+0.18), energy percent of fat (p=0.04, r=+0.01) and fast food frequency (p=0.026, r=+0.139) had significant relationship with BMI percentile. There was a significant relationship between snack frequency and weight status in high school adolescent girls (p=0.023). Data analyzed indicated that physical activity had significant relationship with weight status in adolescent girls (p= 0.0001). The findings suggest that make physical activity enjoyable and improvement food habit among adolescent girls are necessary to induct.Keywords: Physical Activity, Dietary Habit, Adolescent Girls, Weight Status
