Association between quality and quantity of carbohydrate intake with selected anthropometric indices among primary school girls in Kerman city, Iran: a cross-sectional study

BACKGROUND

The school-age is a crucial period of physical and cognitive growth, which requires an assessment of dietary intake and its influence on body weight and height. This study aims to determine the association between the quality and quantity of carbohydrate intake with selected anthropometric indices in primary school girls in Kerman City, Iran.

METHODS

This cross-sectional study was conducted on 330 primary school girls ages 6-12 years in Kerman. We used a validated and reliable dish-based 185-item food frequency questionnaire to evaluate people's food intake. We assessed the amount of carbohydrates in children's diets as the percentage of daily calories and grams per day. We used dietary fiber intake (grams/day), the glycemic load, the ratio of whole grain to total grain, and the ratio of solid carbohydrates to total carbohydrates to assess carbohydrate quality. Height, weight, and arm circumference were measured. We calculated body mass index (BMI) by dividing the weight in kilograms by the height in centimeters squared. We used the World Health Organization z-scores charts for girls 5 to 19 years old to assess z-scores for BMI-for-age (BAZ), height-for-age (HAZ), and weight-for-age (WAZ). Socioeconomic status and physical activity were assessed. We used ANOVA and ANCOVA statistical tests to assess the association between anthropometric indices and carbohydrate quantity and quality parameters.

RESULTS

Participants with the highest amount of carbohydrate intake had significantly higher anthropometric indices, including arm circumference, BMI-for-age z score (BAZ), and Height-for-age z score (HAZ) (p < 0.001, p < 0.001, and p = 0.009, respectively). With the increase in glycemic load (GL) and dietary fiber intake, anthropometric indices including arm circumference (GL: p < 0.001, Fiber: p < 0.001), BAZ (GL: p < 0.001, Fiber: P < 0.001), and HAZ (GL: P = 0.009, Fiber: p < 0.001) increased significantly.

CONCLUSIONS

We concluded that there was a positive association between the amount of carbohydrate intake and anthropometric indices (MUAC, BAZ, and HAZ). Also, with the increase in glycemic load and dietary fiber intake, the anthropometric indices including MUAC, BAZ, and HAZ increased.

Association of healthy eating index and anthropometric indices among primary school girls in southeast of Iran: a cross-sectional study

BACKGROUND

The school-age period is marked by substantial advancements in physical and cognitive development, highlighting the importance of assessing the diet quality and its impact on body weight and height. The main objective of this study was to evaluate the association between diet quality and selected anthropometric indices of primary school girls in southeast of Iran using the healthy eating index-2015 (HEI-2015).

METHODS

This cross-sectional study involved 330 students aged 6-12 years from 10 primary schools in Kerman City. Standard protocols and a dish-based food frequency questionnaire were employed to evaluate anthropometric indices and dietary intake. The HEI-2015 was utilized to assess the quality of participants' diets, with a total score ranging from zero to 100, based on thirteen food score components.

RESULTS

In the present study, older participants had higher HEI scores (p = 0.02). Additionally, participants in the highest tertile of HEI score had greaterodds of being overweight (OR: 2.13; CI = 1.17-3.85, P = 0.011) and had higher intakes of whole fruits, total fruits including fruit juice, whole grains, total protein foods, seafood and plant proteins, greens, and beans (p < 0.05). However, no significant association was found between HEI score and other anthropometric indices, obesity, and thinness.

CONCLUSIONS

The study found no significant association between HEI scores and the likelihood of being thin or obese. However, children with the highest HEI scores were more likely to beoverweight. Therefore, it is recommended to implement health programs for primary school girls in Kerman to improve their eating habits and reduce the risk of overweight and obesity.

Adherence to plant-based dietary patterns and anthropometric indices among primary school girls in Kerman: A cross-sectional study

The objective of the study was to evaluate the association between adherence to plant-based dietary patterns and anthropometric indices among primary school girls in Kerman. This cross-sectional study included 330 girls aged 6-12. A reliable and validated dish-based food frequency questionnaire was used to collect dietary data. Weight, height, and mid-arm circumference were measured, and z-score charts from the World Health Organization for girls between the ages of 5 and 19 were utilized. We used Satija et al. method to calculate plant-based diet index scores. After adjusting for age and energy, participants in the higher tertile of the overall plant-based diet index (PDI) had a lower height-for-age z score (HAZ) (0.38±0.12 vs. 0.59±0.12 kg; P = 0.033). Higher unhealthful plant-based diet index (uPDI) scores were significantly associated with decreased HAZ in models 2 (p = 0.028) and 3 (p = 0.035). A higher PDI score was associated with lower odds of being underweight and overweight, respectively (Model 1: P trend = 0.007, <0.001; Model 2: P trend = 0.010, 0.001). A significant inverse association was found between healthful plant-based diet index (hPDI) scores and underweight risk in the crude and adjusted models. (Model 1: P trend = 0.021; model 2: P trend = 0.018; Model 3: P trend = 0.031). Higher uPDI scores were associated with increased odds of being overweight and obese in all three models (Model 1: p trend<0.001; Model 2: p trend<0.001; Model 3: p trend = 0.001). We concluded that children who followed a plant-based diet had lower odds of being overweight and obese. Higher scores on the hPDI were linked to a decreased risk of being underweight, while higher scores on the uPDI were associated with an increased risk of being overweight and obese. The study suggests healthy plant-based diet may benefit children's weight and growth.

A217 A REVIEW OF MOBILE HEALTH APPLICATIONS FOR INDIVIDUALS LIVING WITH INFLAMMATORY BOWEL DISEASE USING MOBILE APPLICATION RATING SCALE (MARS)

Background

Inflammatory bowel disease (IBD) is a chronic disorder that can be managed but not cured. The relapsing and remitting symptoms of IBD impact patients' quality of life and is associated with considerable healthcare costs. Different mobile health apps have been developed around the world for IBD and other chronic medical conditions. These apps can potentially decrease healthcare utilization and the burden of the disease.

Purpose

We aimed to review IBD mobile health apps available in English and evaluate their quality and content.

Method

We searched the Apple Store and Play Store in July 2022 using IBD-related keywords (e.g., “IBD,” “Crohn,” “Crohns,” “colitis,” “ulcerative colitis,” and “inflammatory bowel disease.”) to identify apps for iOS and Android devices, respectively. We included apps available in English, designed specifically for IBD, and free to download and use. Two researchers reviewed, rated, and evaluated the retrieved apps independently. The Mobile App Rating Scale (MARS) was used to rate the included apps. The MARS rates apps on a scale of 1 to 5 and includes an overall score as well as scores for engagement, functionality, information, aesthetics, and subject quality. A score ≥3 is deemed acceptable.

Result(s)

Search queries yielded 88 relevant apps, of which 38 met the inclusion criteria and were included in this review. The included apps for IBD were most tracking and monitoring symptoms of the disease (n=22). Two of the apps were affiliated with universities, and three of the apps were specifically developed for children. In addition, 11 apps were designed for IBD, regardless of disease subtype (Crohn’s disease [CD] or ulcerative colitis [UC]), and 27 apps were designed specifically for either UC or CD. The mean MARS score for IBD apps was 3.3 (SD=0.6), with more than half deemed acceptable. Apps scored highest on the functionality (mean=3.7, SD=0.6) and information (mean=3.6, SD=0.5) dimension of MARS and lowest on the engagement dimension (mean=3, SD=0.8).

Conclusion(s)

Most IBD-related apps provide acceptable information and functionality but should improve their engagement to be welcomed by users. This review provides a roadmap for improving available apps and future app development for individuals with IBD. App developers in the field of IBD must ensure they create high-quality, engaging, esthetic and evidence-based apps.

Optimization low-fat and low cholesterol mayonnaise production by central composite design

In this study, the optimized process variables for mayonnaise low in cholestrol and fat, which contained soy milk as a yolk substitute with different levels of Xanthan gum, Zodo gum, and oil, were determined by response surface methodology using a central composite design. Polynomial equation was fitted with an insignificant lack of fit factor in order to study the relationship between variables and responses including apparent viscosity, consistency coefficient, flow index, firmness, and stability of mayonnaise sauces. Results showed that increased amounts of Xanthan gum, Zodo gum and oil led to an increase in the apparent viscosity, the consistency coefficient, the firmness/emulsion stability of the mayonnaise, while the mayonnaise flow index was reduced. The interaction effects between Xanthan gum and Zodo gum, and between Xanthan gum and oil were significant on apparent viscosity. Optimum conditions of variables were obtained due to response ranges of commercial mayonnaise as following ingredients: 0.25% Xanthan gum, 3.84% Zodo gum, 37.50% oil, and with the replacement of 63.61% soy milk. Yolk, however, was replaced with soy milk without emulsion fracture up to 100%. This study showed good potential for Zodo gum native mixed with Xanthan gum and soy milk to be used as a fat and yolk substitute in mayonnaise, respectively.
