Assess Weight Status Research Articles

Nutrition, Physical activity and Obesity in Moroccan High School students

Obesity is epidemic in Morocco and on the rise in adolescents. Low physical exercise is mostly associated with weight gain and high incidence of obesity. The consequences of physical inactivity and poor diet produce an obese state in students. This study aims to assess the role of nutrition and physical activity in the prevention of obesity in the high school students in Meknes city-Morocco. 100 high school students aged 14 to 18 years have surveyed to assess weight status, physical activity and dietary habits. By using body mass index (BMI) > 25 kg/m2 and BMI > 30kg/m2 to estimate overweight and obesity. The results show that overweight rates are 23% and obesity rates are 12%. Over 69% of participants indicated consuming less than five servings of vegetables and fruits per day, with over 67% reporting less than 20grams of fibre intake. Additionally, the majority reported engaging in physical exercise on fewer than three days per week. These findings highlight a concerning trend among high school students, indicating a significant gap in meeting physical activity and dietary recommendations. This underscores the necessity for preventive interventions and a deeper understanding of overweight issues in this demographic. Physical activity and dietary changes contribute to weight loss. Overweight and obesity can be prevented by a regular physical activity and healthy diet.

Exploring the Link between Oxidative Stress, Selenium Levels, and Obesity in Youth.

Obesity is a worldwide increasing concern. Although in adults this is easily estimated with the body mass index, in children, who are constantly growing and whose bodies are changing, the reference points to assess weight status are age and gender, and need corroboration with complementary data, making their quantification highly difficult. The present review explores the interaction spectrum of oxidative stress, selenium status, and obesity in children and adolescents. Any factor related to oxidative stress that triggers obesity and, conversely, obesity that induces oxidative stress are part of a vicious circle, a complex chain of mechanisms that derive from each other and reinforce each other with serious health consequences. Selenium and its compounds exhibit key antioxidant activity and also have a significant role in the nutritional evaluation of obese children. The balance of selenium intake, retention, and metabolism emerges as a vital aspect of health, reflecting the complex interactions between diet, oxidative stress, and obesity. Understanding whether selenium status is a contributor to or a consequence of obesity could inform nutritional interventions and public health strategies aimed at preventing and managing obesity from an early age.

Screening of Prediabetic Patients by using HbA1c in District Narowal Pakistan

Background: The prevalence of prediabetes is on the rise globally, with lifestyle factors and obesity being key contributors to the development of the condition. Studies have consistently shown a link between higher Body Mass Index (BMI) and an increased risk of progressing from prediabetes to type 2 diabetes mellitus (T2DM). Objective: This study aimed to determine the prevalence of prediabetes and its association with BMI and lifestyle factors in District Narowal, Pakistan. Methods: A cross-sectional study was conducted with 200 participants from District Narowal. HbA1c levels were measured to classify participants into non-diabetic (4-7%), prediabetic (7-10%), and diabetic (10-13% and 13-16%) groups. BMI was calculated for each participant to assess weight status. Lifestyle factors were evaluated using a standardized questionnaire. Statistical analyses included the independent t-test for mean comparison and standard deviation assessment, with a significance level set at P < 0.05. Results: Out of 200 participants, 81 (40.5%) were non-diabetic, 60 (30%) were prediabetic, and 16 (8%) were classified as diabetic. The mean HbA1c levels for non-diabetic, prediabetic, and diabetic individuals were 5.7%, 8.5%, and 14.5%, respectively. BMI assessment revealed that higher HbA1c levels were associated with higher BMI, and lifestyle analysis indicated a high consumption of ultra-processed foods among prediabetic individuals. Conclusion: The study found a notable prevalence of prediabetes in District Narowal, with a significant association between higher BMI and poor dietary habits with elevated HbA1c levels. These findings suggest the necessity of public health strategies focusing on weight management, nutritional education, and lifestyle modification to prevent the progression of prediabetes to T2DM.

Academic achievement prediction in secondary education by decision tree analysis

The aim of the present study was to develop a predictive model of academic achievement (school success or failure) by applying a decision tree analysis. A cross-sectional study was carried out to design a system for the early detection of academic failure. 219 adolescents (aged 14 to 16) participated and information on their socioeconomic status, body mass index (BMI) percentile, physical activity, leisure time spent in front of screens, enjoyment, hope, anger, anxiety, boredom, behavioral engagement, emotional engagement, cognitive engagement, self-perceived school performance and intention to go to university was collected as input variables in decision tress analysis. 6 failure and 3 success groups were found able to predict academic performance. Good accuracy was obtained in the training (80.11 %) and validation (81.40 %) datasets of the decision tree. It is possible to predict academic failure or success by assessing weight status, physical activity, anger and hope during school attendance, intention to go to university and self-perceived school performance.

Perceived Quality of Life Is Related to a Healthy Lifestyle and Related Outcomes in Spanish Children and Adolescents: The Physical Activity, Sedentarism, and Obesity in Spanish Study.

Maintaining a healthy lifestyle is crucial for safeguarding the well-being and quality of life perception, appropriate growth, and development of children and adolescents, while also mitigating the risk of future adult-onset diseases. To assess associations between perceived quality of life and healthy lifestyle and related outcomes in Spanish children and adolescents. Cross-sectional analysis of 8-16-year-old children and adolescents (n = 3534) were included in the nationwide study of Physical Activity, Sedentarism, and Obesity in Spanish Youth (PASOS). Data were collected through (1) questionnaires on health-related quality of life (HRQoL), healthy lifestyle outcomes (dietary intake, physical fitness, sleep, and screen time), and (2) anthropometric measurements for weight status assessment. Data were analysed by logistic regression, using the health-related quality of life (HRQoL) as the grouping variable. Participants with a lower HRQoL were those with a lower adherence to the MedDiet and lower achievement of the recommended daily intake of fruit and vegetables. They were also less likely to follow the recommendations for screen time and sleep (with the exception of the weekend) compared to participants with a higher HRQoL. Participants with a lower HRQoL showed a lower healthy weight status and poorer physical fitness than those with a higher HRQoL. Healthy eating habits, healthy weight status (normal weight), appropriate sleep time, physical fitness, and limited screen time play a crucial role in the perceived quality of life in children and adolescents.

Сравнительная характеристика перинатальных исходов у женщин с семейной средиземноморской лихорадкой и в контроле

The aim of the study is to compare the reproductive outcome of women with familial Mediterranean fever (FMF) and a control sample. An observational cohort study compares the outcomes in 251 women with FMF to 312 without FMF. A study of perinatal outcomes showed that weight, height and neonatal status assessment at birth were comparable in both groups. The average body weight of the newborn was 2800±500g in the FMF group and 2770±580g in the control group (p≤0,05), the average height was 48±2,5cm and 49±3,0cm (p≤0,001), respectively. Apgar score in the first and fifth minutes of life: 7,6±0,6 and 7,7±0,7 points, (p≤0,05) and 8,4±0,2 and 8,7±0,5 points, (p≤0,01) respectively. Fetal distress was detected in 2,0% in group 1 and in 2,5% in group 2; CDF – 1,6% and 2,6, PS – 31,5% versus 45,5% (p≤0,001); postpartum hemorrhage – 0% and 0.8%; maternal mortality – 0% and 0%, respectively. Perinatal outcomes were comparable in patients with Familial Mediterranean fever and control group.

Accuracy of Assessing Weight Status in Adults by Structured Observation

The assessment of weight status is important in many epidemiological studies, but its direct measurement is not always possible. Self-reported weight and height are often used, although previous research reported low accuracy. This study aimed to test the ability of trained observers to accurately estimate weight status in adults using structured observation. A cross-sectional study was conducted. For each participant, height and weight were estimated in categories, and weight status was recorded using Stunkard’s body figures, by two trained observers. Height and weight were also measured, using standardized procedures. Subjects were classified according to World Health Organization body mass index (BMI) cut-offs from objective measurements and from the BMI assigned to each body figure. Sensitivity, specificity, and likelihood ratios were calculated to assess the accuracy of estimating weight status by observation. Kappa was used to test inter-observer reliability. A total of 127 participants were assessed, 70 women and 57 men, aged between 19 and 89 years (mean ± standard deviation: 50.3 ± 16.3 years). Most participants were overweight or obese (64.3% women; 78.9% men). The sensitivity and specificity of overweight/obesity status identification were 72.8% and 78.4%, respectively. Observers’ gender, participants’ gender, and participants’ age were significantly associated with the estimation of overweight/obesity. The agreement between observers was moderate for BMI estimates (κ = 0.52) but substantial when distinguishing normal weight from overweight/obesity (κ = 0.67). Trained observers were able to distinguish normal weight from overweight/obesity with high sensitivity and specificity, and substantial interrater reliability. This innovative methodology showed potential for improvement through enhanced training techniques. The use of structured observation may be a useful and accurate alternative to self-reported weight status assessment, whenever anthropometric measurement is not achievable.

EPH5 Validity and Accuracy of Weight Status-Related Diagnosis Codes Among Hospitalized Patients in the United States: 2017−2021

Real-world administrative databases are increasingly used to generate evidence to support clinical and healthcare decision making. Abnormal weight status is associated with many health outcomes and needs to be considered in epidemiological and health outcomes research. Due to the lack of vitals data in administrative databases, assessment of abnormal weight status is often dependent on International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) diagnosis codes. We evaluated the validity and accuracy of weight status-related ICD-10-CM codes against vital measurements.

Assessment of Weight Status, Food Security Level, and Fiber Intake Among Hispanic/Latino Adults Residing in New Hampshire

ObjectivesTo assess weight status, food security level, and dietary intake, emphasizing consumption of fiber-rich foods, among adults of Hispanic/Latino background. MethodsThis cross-sectional phone-based survey was administered in English or Spanish, and included questionnaires on weight history, dietary intake (NHANES Dietary Screener Questionnaire), and food security (USDA Household Food Security Survey Module) as experienced before and during the COVID-19 pandemic. Eligible participants were New Hampshire adult residents who identified as Hispanic/Latino. Responses were scored using protocols by questionnaire developers. Analysis of covariance was applied to determine the relationship between weight status, food security level, and dietary intake. Age and gender were included as covariates. ResultsParticipants (N = 73; mean (SD) age = 44 (15) years; 84% female) were predominantly immigrants (85%) who had lived in the US for 12.1 (9.4) years or were US citizens of Puerto Rican origin (11%). Self-perception of health status noted as ‘good,’ ‘very good,’ or ‘excellent’ was reported by 81% of participants. There was a high prevalence of overweight (35%) and obesity (33%), with an average self-reported body mass index (BMI) of 28.7 (5.5) kg/m2. Weight gain during the pandemic was reported by 44% of participants, particularly those with obesity (67%), while weight status was perceived to be in the healthy range by 49% of participants. Perceived weight status and BMI category matched for 48% of subjects with overweight and 88% for subjects with obesity. Estimated daily consumption of dietary fiber was lower (15 (2.4) g/d) than recommended levels (22–34 g/d) but was not correlated with food security level or BMI. On average, men consumed more fiber (18.7 vs. 14.7 g/d, p < .0001) and vegetables (1.8 vs. 1.5 cup equivalents/d, p < .0001) than women. Low and very low food security increased from 25% pre-pandemic to 27% during the pandemic, while marginal food security increased from 10% to 16%. ConclusionsThe exacerbation of food insecurity during the pandemic, along with a high burden of overweight/obesity, low awareness of overweight status, and low fiber intake among NH Hispanics warrant the development of interventions to enhance nutrition security and weight management in this population.

The Sleep-Obesity Nexus: Assessment of Multiple Sleep Dimensions and Weight Status Among Victorian Primary School Children.

PurposeTo examine the association between sleep and weight status across multiple dimensions of sleep (duration, efficiency, quality and timing) and assess the cumulative influence of these dimensions on the overall sleep-obesity association.Participants and MethodsCross-sectional data from 2253 students aged 8.8 to 13.5 years participating in two monitoring studies across regional Victoria was analyzed. Students were invited to have measures of height and weight taken and to complete a self-report electronic questionnaire on demographic characteristics and health behaviors. Logistic regression models were used to assess association between sleep dimensions and BMI z-scores.ResultsBeyond sleep duration, poor perceived sleep quality, delayed sleep initiation, later bed times and sleep-wake timing, all significantly increased the odds of overweight/obesity (OR 1.47, 95% CI: 1.07–2.01; OR 1.25, 95% CI: 1.02–1.55; and OR 1.70. 95% CI: 1.28–2.28, respectively). Additionally, a cumulative effect of having multiple poorly scored sleep dimensions was found, where four or more poorly scored sleep dimensions more than doubled the odds of overweight/obesity among children (OR 2.25, 95% CI: 1.41–3.58).ConclusionThis study highlights the importance of measuring and considering multiple dimensions of sleep, along with the individual and additive influence of the sleep dimension on the sleep-obesity nexus.

Symptoms and Comorbidities Differ Based on Race and Weight Status in Persons with HIV in the Northern United States: a Cross-Sectional Study

BackgroundPersons with HIV (PWHIV) on highly active antiretroviral treatments (HAART) may require specialized care based on health and demographic indicators. This study investigated the association of comorbidities, race, weight status, and gastrointestinal (GI) and cardiovascular (CV) symptoms among PWHIV.MethodsThe Symptom Checklist, Co-Morbidity Questionnaire, and Sociodemographic Questionnaire were used to assess weight status and GI and CV symptoms among 283 PWHIV. Data were analyzed using latent class analysis on John’s Macintosh Project 13 Platform.ResultsParticipants were majority Black (50%), 69% male, and 35% AIDS diagnosed. Ages were 25 to 66. Clusters included least symptomatic status, weight gain, and weight loss by Black and non-Black participants. The non-Black weight gain cluster reported a higher incidence of AIDS (70.6% vs 38.2%), nausea (70.6% vs 17.6%), diarrhea (70.6% vs 26.5%), and shortness of breath (58.8% vs 20.6%) compared to the Black weight gain cluster. The Black weight loss cluster reported a higher incidence of CV symptoms such as chest palpitations (42.2% vs 2.7%), chest pain (44.4% vs 8.1%), and shortness of breath (73.3% vs 35.1%). Moreover, the Black weight loss cluster reported a higher incidence of all GI symptoms with the most prominent being diarrhea (71.1% vs 48.6%) compared to the non-Black weight loss cluster.ConclusionsThe existing racial disparities in health-related quality of life for PWHIV may be improved through precision health and nutrition modifications. Continued research is needed investigating differential health outcomes among PWHIV on HAART.Clinical Trial Registration NumberNCT00222716. Registered 22 September 2005.

Poor sleep quality, excessive daytime sleepiness and association with mental health in college students

Aim To estimate the prevalence of poor sleep quality and excessive daytime sleepiness (EDS) among college students and to analyse their association with aspects of mental health. Subjects and methods A cross-sectional study carried out with 1113 college students, enrolled in full-time courses at a public university in the Mid-West region of Brazil. Data were collected through a self-administered questionnaire with questions about demographics, socioeconomics, mental health, sleep quality, and EDS. Measurements of weight and height were taken to assess weight status using the body mass index. Multivariate logistic regression models were used to estimate the associations between perceived stress (classified as light, moderate, and high) and presence of depressive symptoms with poor sleep quality and presence of EDS. Results High prevalence of poor sleep quality (65.5%) and EDS (55%) was observed. In the adjusted models, poor sleep quality was significantly associated with moderate and high perceived stress and presence of depressive symptoms. For EDS, there was also a significant association with moderate and high perceived stress and presence of depressive symptoms. Conclusions High prevalence of poor sleep quality and EDS was found among college students. Perceived stress and presence of depressive symptoms were significantly associated with both evaluated outcomes.

Predicting height from ulna length for the determination of weight status in New Zealand adolescents: A cross-sectional study.

The measurement of height is crucial for weight status assessment. When standing height is difficult to measure, ulna length may offer a convenient and accurate surrogate of height measure. Adolescence is a period of accelerated linear growth; hence, the validation of age-specific equations that predict height from ulna length in adolescents is warranted. The present study aimed to develop and validate age- and sex-specific equations for predicting height from ulna length in New Zealand adolescents. Height, weight and ulna length were measured in 364 adolescents (n=110males, n=254 females) aged 15.0-18.8years, who were enrolled in the SuNDiAL (Survey of Nutrition Dietary Assessment and Lifestyle) project, a cross-sectional survey performed in 2019 and 2020. Regression models were used to determine equations to predict height from ulna length. Agreement between measured and predicted height, body mass index (BMI) and BMI z-score was assessed with intra-class correlation coefficients (ICC) and Bland-Altman plots. Sensitivity and specificity were calculated for classifying obesity. Strong agreement was found between predicted and measured height (ICC=0.78; mean difference=0; 95% confidence interval=-0.5 to 0.5cm) and BMI (ICC=0.95; mean difference=0; 95% confidence interval=-0.1 to 0.1kgm-2 ). Predicted height was 88.1% accurate when classifiying weight status, showing high sensitivity (93.8%) and specificity (99.4%) for classifying obesity. Ulna length measurement can accurately estimate height and subsequently weight status in New Zealand adolescents aged 15-18years.

Involvement of children in hands-on meal preparation and the associated nutrition outcomes: A scoping review.

Emerging research has explored hands-on meal preparation as a strategy to improve children's nutrition-related outcomes. This scoping review was conducted to describe the extent of studies on children's involvement in hands-on meal preparation and the related psychosocial outcomes, actual nutrition behaviour/food consumption and weight status. Scoping review methodology was used to select relevant studies, as well as extract and collate the data. Four databases (PubMed, Google Scholar, Science Direct and Cochrane Database of Systematic Reviews) were searched from the earliest available time up to December 2020. Observational studies, experimental studies and reviews that were conducted among children aged 5-12years old and published from 2010 to 2020 were retrieved. Studies extracted involved children in hands-on healthy meal preparation activities and explored the associated nutrition outcomes. In total, 28 studies (5 observational studies, 21 experimental studies, 2 reviews) were included in the final review. Studies conducted demonstrated improvement in children's psychosocial outcomes and actual nutrition behaviour/food consumption after participating in hands-on meal preparation activities, despite differences in methodology, programme content and settings (countries/cultural origins). Limited studies assessed children's nutrients intake and weight status. The current review suggests that hands-on meal preparation comprises approach for instilling positive perceptions towards nutrition/healthy foods, potentially improving children's diet. Future studies should include the assessment of nutrient intake and weight status. The long-term sustainability of these nutrition outcomes should be explored.

Discordance between Body-Mass Index and Body Adiposity Index in the Classification of Weight Status of Elderly Patients with Stable Coronary Artery Disease.

Background and Aims: Body-mass index (BMI) is a popular method implemented to define weight status. However, describing obesity by BMI may result in inaccurate assessment of adiposity. The Body Adiposity Index (BAI) is intended to be a directly validated method of estimating body fat percentage. We set out to compare body weight status assessment by BMI and BAI in a cohort of elderly patients with stable coronary artery disease (CAD). Methods: A total of 169 patients with stable CAD were enrolled in an out-patient cardiology clinic. The National Research Council (US) Committee on Diet and Health classification was used for individuals older than 65 years as underweight BMI < 24 kg/m2, normal weight BMI 24–29 kg/m2, overweight BMI 29–35 kg/m2, and obesity BMI > 35 kg/m2. In case of BAI, we used sex- and age-specific classification of weight status. In addition, body fat was estimated by bioelectrical impedance analysis (BImpA). Results: Only 72 out of 169 patients (42.6%) had concordant classification of weight status by both BMI and BAI. The majority of the patients had their weight status either underestimated or overestimated. There were strong positive correlations between BMI and BImpA (FAT%) (R = 0.78 p < 0.001); BAI and BImpA (FAT%) (R = 0.79 p < 0.001); and BMI and BAI (R = 0.67 p < 0.001). BMI tended to overestimate the rate of underweight, normal weight or overweight, meanwhile underestimating the rate of obesity. Third, BMI exhibited an average positive bias of 14.4% compared to the reference method (BImpA), whereas BAI exhibited an average negative bias of −8.3% compared to the reference method (BImpA). Multivariate logistic regression identified independent predictors of discordance in assessing weight status by BMI and BAI: BImpA (FAT%) odds ratio (OR) 1.29, total body water (%) OR 1.61, fat mass index OR 2.62, and Controlling Nutritional Status (CONUT) score OR 1.25. Conclusions: There is substantial rate of misclassification of weight status between BMI and BAI. These findings have significant implications for clinical practice as the boundary between health and disease in malnutrition is crucial to accurately define criteria for intervention. Perhaps BMI cut-offs for classifying weight status in the elderly should be revisited.

Development of a BMI-Assigned Stunkard Scale for the Evaluation of Body Image Perception Based on Data of the SOS Reference Study

Introduction: Stunkard’s figure rating scale is a widely used tool to assess weight status and, more recently, body image perception in people with obesity. However, large population-based studies on Europeans linking this scale’s silhouettes with measured BMI values are lacking. Therefore, we used measured weight and height data from the Swedish Obese Subjects (SOS) reference cohort to assign a mean BMI to each of the 9 Stunkard Scale silhouettes and to define silhouette cutoff values for categorizing people with obesity and overweight. Methods: A total of 1,128 participants from the SOS reference cohort were included (54% females, BMI = 25.2 [ranging from 17.6 to 45.4] ±3.8 kg/m2, and age = 50 [ranging from 36 to 62] ±7 years [means ± standard deviation]). Patients estimated their own body size by choosing a silhouette of the Stunkard Scale. A mean BMI, based on measured weight and height, was assigned to each male and female silhouette of the Stunkard Scale. Measured BMI values were compared with BMI values calculated by simple linear regression analysis. ROC analysis was used to test accuracy of discrimination and the Youden index to assess optimal cutoff. Results: Figure ratings and BMI were strongly correlated in men, r (518) = 0.76, p < 0.001 and women, r (606) = 0.80, p < 0.001. Silhouette selection significantly predicted BMI values in men, β = 16.03, t (518) = 25.30, p < 0.001, and women, β = 12.06, t (606) = 32.98, p < 0.001, and explained a significant proportion of variance in BMI values in men, R2 = 0.55, F (1, 518) = 639.98, p < 0.001, and women, R2 = 0.64, F (1, 606) = 1,087.88, p < 0.001. ROC curve analyses resulted in an optimal cutoff value of 6 for identifying people with obesity and 5 for overweight. Conclusion: Stunkard’s figure rating scale can be used with confidence to assess weight status. Silhouette selection accurately classifies subjects as overweight or obese.

Determination of Body Fat Ratio Standards in Children at Early School Age Using Bioelectric Impedance.

Background and objectives: Body mass index (BMI) is commonly used to assess the proportionality of body mass; however, there are currently no standards for assessing the weight status of the child population for the needs of epidemiological studies. This study aims to establish bioelectric impedance analysis (BIA) standards for assessing the body weight of children (body fat, visceral fat) using BMI percentile growth charts. Materials and Methods: The study was implemented in a group of 1674 children (816 boys and 858 girls), ages 6 to 11. To classify the subjects at a percentile level, the percentile growth charts from the 6th national anthropological study in the Czech Republic were used. Body composition parameters were ascertained by BIA. Results: Body fat (%) and visceral fat standard values were determined for all age categories. The standards were in three-stages, enabling the determination of underweight, normal weight and overweight children aged 6–11 years. For boys with proportionate body mass, standard body fat values ranging from 14.3–16.0% to 15.5–18.0% were determined, while for girls’ values ranging from 16.7–19.4% to 18.3–20.5% were determined, depending on age. As far as visceral fat is concerned, standard values in boys ranging from 30.3–36.9 cm2 to 36.1–44.9 cm2 and in girls 30.3–36.9 cm2 to 36.1–44.9 cm2 were determined, depending on age. Conclusions: Standards for assessing weight status are applicable to children aged 6–11 years, while it can be confirmed that BMI can be considered as an objective tool in assessing body mass and body composition in children.

"What's a normal weight?" - Origin and receiving country influences on weight-status assessment among 1.5 and 2nd generation immigrant adolescents in Europe.

Many adolescents struggle with adequately assessing their weight-status, often leading to unnecessary weight-related interventions or preventing necessary ones. The prevalence of weight-status over- and underestimation differs considerably cross-nationally, suggesting that individual weight-status assessment is informed by cross-nationally differing standards of evaluation. For adolescents with a migration background, this brings up the possibility of a simultaneous influence of origin- and receiving country standards. The current study examines the magnitude of both influences using data from the 2014 Health Behaviour in School-Aged Children study. The cross-national design of the study enabled us to aggregate weight-evaluation standards for 41, primarily European, countries. Subsequently, we identified a sample of 8 124 adolescents with a migration background whose origin as well as receiving country participated in the study. Among those adolescents, we assessed the effects of origin and receiving country weight-evaluation standards using cross-classified multilevel regression analyses. Descriptive analyses revealed considerable differences in weight-evaluation standards between the countries. Regression analyses showed that both origin- and receiving country weight-evaluation standards were significantly associated cross-sectionally with weight-status assessment among the immigrant adolescents, with a stronger impact of receiving country standards. Results illustrate the context-sensitivity of adolescent weight-status assessment and reinforce the theoretical notion that immigrant adolescent development is not only informed by factors pertaining to their receiving country but also, albeit to a lesser extent, by those pertaining to their origin country.

P33 Assessment of Dietary Behaviors and Weight Status Among Adolescents from Multicultural Families and Non-Multicultural Families in Korea

<h3>Background</h3> As Korean adolescents in multicultural families (MF) might experience health disparities, assessing their specific nutritional health status is necessary to design effective and tailored nutrition education programs. <h3>Objectives</h3> This study was the first step to develop a nutrition education program for the Korean adolescent in MF. The aim of this study was to identify nutritional health problems of MF' adolescents through comparing dietary and lifestyle behaviors and weight status among Korean adolescents from MF and non-multicultural families (non-MF). <h3>Study Design, Setting, Participants</h3> This study included 111,067 adolescents aged 12–18 years (MF = 1,751, non-MF = 109,316) from the 2017–2018 Korea Youth Risk Behavior Surveys. <h3>Measurable Outcome/Analysis</h3> Data on dietary and lifestyle behaviors were self-reported using a web-based questionnaire and included foods consumption, alcohol drinking, smoking, physical activity, weight control efforts, and perceived health status. Body mass index (BMI) was calculated using the self-reported height and weight (kg/m²). Weight status was determined based on the 2017 Korean National Growth Chart: underweight (weight-for-age <5th percentiles), overweight (85th≤ BMI-for-age <95th percentiles), and obesity (BMI-for-age ≥95th percentiles). <h3>Results</h3> Using a multiple logistic regression after adjustment for sex, school level, residence, and household income, adolescents from MF showed higher odds ratios (ORs) for having underweight (OR = 1.60, 95% CI = 1.29–1.99) and obesity (OR = 1.22, 95% CI = 1.03–1.43) compared to those from non-MF. Adolescents from MF were less likely to intake fruit ≥5 times/week (OR = 0.86, 95% CI = 0.76–0.96) compared to adolescents from non-MF. Boys in MF showed a lower OR for having vegetable ≥5 times/week (OR = 0.74, 95% CI = 0.60–0.92) than boys in non-MF. Compared to non-MF' adolescents, the OR for engaging in physical activity ≥3 days/week was 0.83 (95% CI = 0.74–0.94) in MF' adolescents. <h3>Conclusions</h3> Korean adolescents in MF showed higher risks for having underweight and obesity as well as unhealthy dietary behaviors compared to those in non-MF. Our findings can be used to develop nutrition education programs for adolescents from MF.
