Reproducibility and Validity of a Semi-Quantitative Food Frequency Questionnaire for Children Aged 6-12 in Western China.

The Food Frequency Questionnaire (FFQ) is often used to assess dietary intake in large-scale epidemiological studies. This study aimed to evaluate the reproducibility and validity of the FFQ newly developed for children aged 6 to 12 in western China. A total of 133 children were included in the analysis, and all the children and their caregivers completed the FFQs twice with a three-month interval period, and three 24 h recalls were carried out one month after the first FFQ. We assessed the relative validity and reproducibility using various methods, such as the Spearman correlation coefficient, intra-class correlation coefficient, weighed Kappa, quartile agreement, and Bland-Altman analysis. The Spearman correlation coefficients for food ranged from 0.30 to 0.84, and for nutrients from 0.46 to 0.82 regarding reproducibility. The food intra-class correlation coefficients ranged from 0.20 to 0.85, while nutrients' ranged from 0.37 to 0.75. In terms of relative validity, the average Spearman correlation coefficients for food were 0.20, and 0.30 for energy and nutrients. The energy-adjusted and de-attenuation coefficients were calculated. Moreover, the average percentage of participants misclassified into the extreme quartile for food and nutrients was 8.0% and 7.0%, respectively. Weighted Kappa values indicated acceptable agreement between the FFQs and 24 h recalls. Furthermore, the percentage of results in the limits of agreement (LOA) were all above 93.0%. In conclusion, The FFQ showed good reproducibility and acceptable relative validity for assessing the dietary intake of children aged 6-12 in western China.

Does early fruit juice introduction influence anthropometric outcomes and food consumption at preschool age?

The aim of this study was to evaluate the impact of fruit juice consumption before 6 months of age on Body Mass Index-for-age (BMI-for-age) and food consumption in preschoolers. We conducted a longitudinal study with mothers and their children (n=103) at 6 months and 3-6 years. Weight and height were measured and converted into BMI-for-age z-scores. Food consumption was analyzed using the Food Frequency Questionnaire for Children. Groups were compared using the chi-squared and Student's t-tests. No differences in anthropometric measurements were found at preschool age between children who had been given fruit juice before 6 months and those who had not. Consumption of artificial juice (≥once/day) and sandwich cookies at preschool age was higher in children with early introduction of fruit juice (≤150 days of life) (63.8% versus 35.7%; p=0.028 and 21.3% versus 14.3%; p=0.001, respectively). The prevalence of the consumption of soda (1 to 4 times/week) and chocolate milk (at least once/day) was higher in children who had been given artificial juice before 6 months (69.2% versus 27.4%; p=0.014 and 38.5% versus 69.4%; p=0.027, respectively). It can be concluded that the consumption of sweet foods and sugary beverages was higher in children with early introduction of fruit juice.

Abstract The aim of this study was to evaluate the impact of fruit juice consumption before 6 months of age on Body Mass Index-for-age (BMI-for-age) and food consumption in preschoolers. We conducted a longitudinal study with mothers and their children (n=103) at 6 months and 3-6 years. Weight and height were measured and converted into BMI-for-age z-scores. Food consumption was analyzed using the Food Frequency Questionnaire for Children. Groups were compared using the chi-squared and Student’s t-tests. No differences in anthropometric measurements were found at preschool age between children who had been given fruit juice before 6 months and those who had not. Consumption of artificial juice (≥once/day) and sandwich cookies at preschool age was higher in children with early introduction of fruit juice (≤150 days of life) (63.8% versus 35.7%; p=0.028 and 21.3% versus 14.3%; p=0.001, respectively).

It can be concluded that the consumption of sweet foods and sugary beverages was higher in children with early introduction of fruit juice.

Unhealthy food options in the school environment are associated with diet quality and body weights of elementary school children in Canada.

Increasing evidence links unhealthy food environments with diet quality and overweight/obesity. Recent evidence has demonstrated that relative food environment measures outperform absolute measures. Few studies have examined the interplay between these two measures. We examined the separate and combined effects of the absolute and relative densities of unhealthy food outlets within 1600 m buffers around elementary schools on children's diet- and weight-related outcomes. This is a cross-sectional study of 812 children from thirty-nine schools. The Youth Healthy Eating Index (Y-HEI) and daily vegetables and fruit servings were derived from the Harvard Food Frequency Questionnaire for Children and Youth. Measured heights and weights determined BMI Z-scores. Food outlets were ranked as healthy, somewhat healthy and unhealthy according to provincial paediatric nutrition guidelines. Multilevel mixed-effects regression models were used to assess the effect of absolute (number) and relative (proportion) densities of unhealthy food outlets within 1600 m around schools on diet quality and weight status. Two urban centres in the province of Alberta, Canada. Grade 5 students (10-11 years). For children attending schools with a higher absolute number (36+) of unhealthy food outlets within 1600 m, every 10 % increase in the proportion of unhealthy food outlets was associated with 4·1 lower Y-HEI score and 0·9 fewer daily vegetables and fruit. Children exposed to a higher relative density of unhealthy food outlets around a school had lower diet quality, specifically in areas where the absolute density of unhealthy food outlets was also high.

Validation of a short food frequency questionnaire in small children

Introduction: validated food frequency questionnaires in children are scarce, mostly long, and only provide data about food consumption. Objectives: the aim of this study was to evaluate the reproducibility and validity of a short food frequency questionnaire that estimates energy, nutritional intake, and the frequency of food consumption in children aged between 3 and 6 years. Material and methods: in 49 children (57% boys), the reproducibility and validity of a frequency questionnaire with 41 items was assessed using Spearman's and intraclass correlations, both adjusted and not adjusted for energy. A 6-day record was used as a reference method. Results: reproducibility was high in food groups with correlations > 0.70 for most of them and between 0.5 and 0.7 for meat, fish, potatoes, sweets/soft drinks, and oil. For energy and nutrients correlations were > 0.9 and > 0.7, respectively. Validity was strong to moderate for foods with correlations > 0.7 (dairy and milk) and between 0.4 and 0.7 (sausages, eggs, yogur/cheese, vegetables and oil), and for nutrients with correlations > 0.5 (lipids, AGS, AGP, phosphorus, calcium, vitamin E and vitamin C) and between 0.3 and 0.5 (energy, starches, fiber, MUFA, cholesterol, sodium, magnesium, potassium, retinol, riboflavin, niacin, pantothenic acid, vitamin B6 and folates). All correlations were significant and increased after they had been adjusted for energy. Conclusions: the short food frequency questionnaire for children between 3 and 6 years old has high reproducibility and good validity with results that are as good as those of long food frequency questionnaires.

Soy isoflavone intake is associated with risk of Kawasaki disease

Kawasaki disease (KD) is an acute vasculitis affecting children. Incidence of KD varies according to ethnicity and is highest in Asian populations. Although genetic differences may explain this variation, dietary or environmental factors could also be responsible. The objectives of this study were to determine dietary soy and isoflavone consumption in a cohort of KD children just before disease onset and their mothers' intake during pregnancy and nursing. We tested the hypothesis that soy isoflavone consumption is associated with risk of KD in US children, potentially explaining some of the ethnic-cultural variation in incidence. We evaluated soy food intake and isoflavone consumption in nearly 200 US KD cases and 200 age-matched controls using a food frequency questionnaire for children and in their mothers. We used a logistic regression model to test the association of isoflavones and KD. Maternal surveys on soy intake during pregnancy and nursing showed no significant differences in isoflavone consumption between groups. However, we identified significantly increased KD risk in children for total isoflavone (odds ratio [OR], 2.33; 95% confidence interval [CI], 1.37-3.96) and genistein (OR, 2.46; 95% CI, 1.46-4.16) intakes, when comparing high soy consumers vs nonconsumers. In addition, significantly increased KD risk occurred in Asian-American children with the highest consumption (total isoflavones: OR, 7.29; 95% CI, 1.73-30.75; genistein: OR, 8.33; 95% CI, 1.92-36.24) compared to whites. These findings indicate that childhood dietary isoflavone consumption, but not maternal isoflavone intake during pregnancy and nursing, relates to KD risk in an ethnically diverse US population.

Development of a food frequency questionnaire for children from 7 to 10 years old.

To present and discuss the process of the development of a Quantitative Food Frequency Questionnaire (QFFQ) aimed to 7-10 year-old children. A methodological study was performed based on the application of a Food Diary (FD) fulfilled by 85 children. Based on registered foods, the diet composition in relation to energy and macronutrients was calculated. Foods were grouped into items and the percentage of the contribution of each item to the diet in terms of calories and macronutrients were calculated. The QFFQ was constructed with 92 food items, 76 were selected by Block's method and 16 were identified from other instruments from literature developed for children and adolescents. The food items were grouped in 17 food groups with 3 serving sizes and 7 categories to measure food frequency. Among the food items, the rice was the one that showed the biggest percentage of contribution for energy and carbohydrates. For other nutrients, the meat and the milk were the ones that contributed most to the consumption of proteins and lipids, respectively.

Abstract MP42: Intakes of Sugar-Sweetened Beverages and Total Sugars are Associated with Higher Triglycerides in a Multi-Ethnic Sample of Children

Background: Intakes of sugar-sweetened beverages (SSB) and added sugars have been targeted in efforts to reduce childhood obesity and cardiovascular disease risk factors in children. Although evidence is sparse in children, overconsumption of SSB and added sugars has been linked to greater dyslipidemia in adults. Objectives: To examine the association between intakes of SSB, added sugars, and total sugars, with blood lipids in a multi-ethnic sample of children with prevalent obesity. Methods: In this cross-sectional study, we examined associations between intakes of SSB, added sugars, and total sugars with high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG) in a sample of 276 children aged 8-15 y (mean age 11.8 y; 39% white, 14% black, 16% Hispanic/Latino, 12% Asian, and 19% multi-racial/other) with prevalent overweight/obesity (45% with ≥85 th BMI percentile and 25% with ≥95 th ). Percentage of daily calories from SSB, as well as intakes of added sugars (tsp) and total sugars (g), were estimated using the 2004 Block Food Frequency Questionnaire for Children. HDL-C and TG were obtained from a fasting blood sample. Percentage of calories from SSB, added sugars, and energy-adjusted total sugars were dichotomized at their upper tertile cut-points, specifically, at 7%, 13 tsp, and 116 g, respectively, creating two intake categories for each dietary exposure. ANCOVA was used to analyze the data; covariates were age, sex, race/ethnicity, obesity, total calories, and intakes of saturated fat and dietary fiber. TG was log-transformed prior to analysis; low HDL-C was defined as ≤45 mg/dL and borderline/high TG, as ≥75 (aged ≤9 y) or ≥90 mg/dL (≥10 y). Results: Median daily intake of total sugars was 94.2 g, 47% of which was derived from added sugars (median: 9.9 tsp, range: 1-76 tsp). Only 12% of children followed the American Heart Association calorie-specific recommendations for intake of added sugars. Median contribution of SSB to total calories was 4.4% (range: 0 to 51%), and SSB calories contributed 36% (range: 0 to 100%) of calories from added sugars. Both low HDL-C and borderline/high TG were prevalent (26-27% overall) and were more common in children classified as obese (61% and 53%, respectively) than in those who were not obese (16% and 17%, respectively, P<0.0001 for each); however, intakes of SSB, added sugars, and total sugars did not differ with obesity. In multivariate-adjusted models, higher TG was associated with high intakes of SSB (75.3 vs. 67.6 mg/dL, P=0.04) and total sugars (76.5 vs. 67.0 mg/dL, P=0.01), while the association with added sugars was not significant. There were no associations with HDL-C. Conclusions: Among children with prevalent obesity, higher intakes of SSB and total sugars were associated with higher TG concentrations, but not with lower HDL-C. Further research is needed on the health implications of lower SSB and sugar intakes in diverse samples.

Estado nutricional e consumo alimentar de pré-escolares e escolares de escola privada

Objective: To evaluate the nutritional status and dietary intake adequacy of preschool and school children from a private school. Materials and Methods: Cross-sectional study with 216 children from a private school located in the central region of the city of Sao Paulo, Brazil. Weight and height have been measured and the body mass index has been calculated. Data have been analyzed under the World Health Organization Child Growth Standards. Parents have been requested to fill out a food frequency questionnaire for children. Results: The prevalence of malnutrition was 0.9%, overweight 22.1% and obesity 18.9%. Almost all the food groups have shown inadequate intake, with the exception of oils and fats. The groups of vegetables, fruits, meats, eggs and sweets require special attention. The higher consumption of fruits and vegetables had a statistically significant association with low body mass index. Conclusions: The rates of overweight and obesity are high in this population, besides food inadequacy, highlighting the need of educational activities for this population.

Validation of a food frequency questionnaire for children and adolescents aged 4 to 11 years living in Salvador, Bahia.

To assess the validity of a food frequency questionnaire (FFQ) by applying it to children and adolescents living in Salvador, Bahia. The validity of this FFQ with 98 food items was investigated among 108 children and adolescents who were selected from a sample of 1445 that had been planned for a study on the risk factors for asthma and other allergic diseases. The adults responsible for these children and adolescents gave responses for a 24-hour recall (R24h) and an FFQ. The average energy and nutrient values from the FFQ were compared with those from the R24h by means of the paired t test and Pearson correlation coefficients. The concordance was evaluated using the Bland-Altman method and kappa statistics. The energy and nutrient intake estimated using the FFQ was significantly higher than what was obtained using the R24h. The correlation coefficients adjusted for energy were statistically significant for protein, fat, vitamin C and zinc. The weighted kappa values ranged from 0.06 for vitamin A (p = 0.24) to 0.34 for energy (p < 0.00). The results from the Bland-Altman plots for lipid, protein and zinc showed the most significant validity parameters, and zinc was found to show the best concordance. The results suggest that the FFQ showed satisfactory validity for use in studies involving children and adolescents.

Examining the Relative Validity of an Adult Food Frequency Questionnaire in Children and Adolescents

Dietary factors have been implicated in the pathogenesis of inflammatory bowel diseases (IBD). The aim of the study was to assess the accuracy of a food frequency questionnaire (FFQ) developed in French and English for adults 18 years and older, among subjects ages 7 to 18 years participating in a prospective cohort study. Healthy children and adolescents ages 7 to 18 years were recruited from outpatient orthopedic clinics in a Montréal pediatric hospital. Of the 131 recruits, 65 (86% Francophone) provided a complete 78-item semiquantitative FFQ and 3-day nonconsecutive food records (3D-FR). Parents of young children completed both instruments, whereas older children and adolescents completed them on their own. The FFQ were analyzed using Microsoft Access software for customized data entry and the 3D-FR were analyzed using CANDAT software, both based on the 2007b Canadian Nutrient File. The FFQ overestimated intakes relative to the 3D-FR by around 15%. Spearman rank correlation coefficients between test and reference methods were positive, largely ranged from 0.22 (vitamin C) to 0.57 (saturated fat), and were generally statistically significant (0.05< P < 0.0001). Stronger associations between test and reference methods were found for adolescents (13-18 years) and for girls. Some 77% of participants were jointly classified into the same half of the distribution, with 39% exact agreement and only 6% frank misclassification. The FFQ can be confidently used to rank young subjects on a range of nutrient intakes with the potential to provide useful information on dietary risk factors in the etiology of inflammatory bowel disease. Accuracy could be enhanced by improving completion quality of FFQs, notably by young adolescent boys.
