Validity of dietary assessment methods compared with doubly labeled water in children: A systematic review and meta-analysis. Obes Rev 2024; 25:e13768. [PMID: 38783784 DOI: 10.1111/obr.13768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 04/20/2024] [Accepted: 04/20/2024] [Indexed: 05/25/2024]
Abstract
OBJECTIVES We aimed to validate dietary assessment methods against the gold standard, doubly labeled water (DLW), for estimating total energy intake (TEI). METHODS PubMed, Scopus, Web of Science, and Google Scholar databases were searched until May 2023. Inclusion criteria encompassed studies involving participants aged 1-18 years, employing dietary assessment methods like food records, dietary histories, food frequency questionnaire (FFQ), or 24-h recalls estimating TEI alongside DLW to measure total energy expenditure (TEE). Data were pooled using random-effects meta-analysis models. RESULTS Thirty-three studies were identified, with sample sizes ranging from 9 to 118 participants. Meta-analysis of 22 studies identified underestimation of TEI (mean difference [MD] = -262.9 kcal/day [95% CI: -380.0, -145.8]; I2 = 93.55%) for food records compared with TEE estimated by DLW. Other dietary assessment methods, including food recalls (n = 9) (MD = 54.2 kcal/day [95% CI: -19.8, 128.1]; I2 = 49.62%), FFQ (n = 7) (MD = 44.5 kcal/day [95% CI: -317.8, 406.8]; I2 = 94.94%), and diet history (n = 3) (MD = -130.8 kcal/day [95% CI: -455.8, 194.1]; I2 = 77.48%), showed no significant differences in TEI compared with DLW-estimated TEE. All studies were of high quality. CONCLUSION Food records may underestimate TEI, yet additional research is needed to identify the most accurate methods for assessing children's dietary intake.

Abstract
Total energy expenditure (TEE) is essential for understanding the growth, development, and physical activity of children and adolescents. This study aimed to summarize the existing evidence on TEE measured using the doubly labeled water (DLW) technique in children and adolescents aged 1-18 years. Furthermore, this review compared TEE between obese and normal-weight participants. This systematic review used the PubMed, ScienceDirect, Web of Science, and EBSCO databases. These studies were limited to those published in English between January 2000 and December 2021. Articles presenting objectively measured data on the TEE of children and adolescents aged 1-18 years measured using the DLW method were included. Physical activity level (PAL; TEE/basal metabolic rate [BMR]) and BMR data were also obtained. The search strategy identified 2,351 articles, of which 63 (n=4,283 children and adolescents; 45.4% male) met the selection criteria. The participants in the 10 studies were overweight or obese (n=413). In our study, TEE increased in male and female participants aged 1-18 years. PAL increased with age in males (y=0.0272x+1.3887, r2=0.511) and females (y=0.0199x+1.401, r2=0.335), and the slope of PAL with age did not differ between males and females. The TEE of obese and overweight participants was higher than that of normal-weight participants, but the slope of TEE did not differ between normal-weight (y=132.99x+702.24, r2=0.877) and obese individuals (y=136.18x+1,037.9, r2=0.842). In conclusion, this review provides convincing evidence that daily TEE progressively increases with growth in males and females aged 1-18 years.

Abstract
OBJECTIVE Although research studies increasingly use children as primary reporters in dietary assessments, it is unclear how well children's self-reported intake correlates with independently validated reports of their intake; this meta-analysis assesses that correlation. DESIGN Moderators of the correlation between self-reported and independently validated intake were predicted a priori: type of dietary intake assessment (24 h recall, food diary and food frequency questionnaires), validation measures, parental assistance and age. Online databases were searched for articles published from 1990 to 2014 that compared children's self-reports of dietary intake to validated observations of food intake in children age 4-16. MAIN OUTCOME MEASURES Summary effect size Pearson r between children's self-reported dietary intake and independently validated dietary intake were calculated. RESULTS In k = 32 samples from 23 studies, a statistically significant correlation (r = .48, Z = 7.26, p < .001) was found between children's self-reported dietary intake and independently validated reports of dietary intake. Validation method (Q = 17.49, df = 2, p < .001) and parental assistance (Z = 2.03, p = .042) were significant moderators of this correlation. Self-report methodology (Q = 3.95, df = 2, p = .139) and age (Q = .02, p = .879) were not significant moderators of the distribution of effect sizes. CONCLUSION Together, these results provide baseline information about children's recall in dietary intake assessments conducted with children as primary reporters.

Abstract
Introduction: There is need for employing strategies to minimize measurement errors while administering semi-quantitative FFQ. The current study was planned to adapt and standardize locally available portion sizes for semi-quantitative FFQ to improve its validity and document the process of standardization of portion sizes. Methodology: The study was conducted in 9 villages of the INCLEN-SOMAARTH DDESS (Demographic, Development and Environmental Surveillance Site), Palwal district, Haryana, India. The subjects in these nine villages are part of a cohort study to assess the interaction between societal and household factors with food intake and physical activity of children. Systematic utensil survey was undertaken in 3 randomly chosen households per village i.e. 27 households and the portion sizes were derived from a total of 74 serving utensils. The derived sizes were classified as small (240 ml), medium (320 ml) and large (600 ml). The semi-quantitative FFQ with locally derived portion sizes was then administered to 63 children in 6-12 year age group. Results: The volume of food measured by the reference portion sizes generally being employed in the national surveys, would have been underestimated the food consumed by the child by 55-60% as compared to what was being consumed by the children in the study area. The correlation between food intake assessed by 24-hr recall method and FFQ using derived (local) portion sizes was better as compared to that obtained with the semi-quantitative FFQ done with reference portions. Conclusion: In conclusion, local portion size adaptation of FFQ for semi-quantification is useful to mitigate measurement errors associated with this technique.

Abstract
Mobile phones are becoming important instruments for assessing diet and energy intake. We developed the Tool for Energy Balance in Children (TECH), which uses a mobile phone to assess energy and food intake in pre-school children. The aims of this study were: (a) to compare energy intake (EI) using TECH with total energy expenditure (TEE) measured via doubly labelled water (DLW); and (b) to compare intakes of fruits, vegetables, fruit juice, sweetened beverages, candy, ice cream, and bakery products using TECH with intakes acquired by 24 h dietary recalls. Participants were 39 healthy, Swedish children (5.5 ± 0.5 years) within the ongoing Mobile-based Intervention Intended to Stop Obesity in Preschoolers (MINISTOP) obesity prevention trial. Energy and food intakes were assessed during four days using TECH and 24 h telephone dietary recalls. Mean EI (TECH) was not statistically different from TEE (DLW) (5820 ± 820 kJ/24 h and 6040 ± 680 kJ/24 h, respectively). No significant differences in the average food intakes using TECH and 24 h dietary recalls were found. All food intakes were correlated between TECH and the 24 h dietary recalls (ρ = 0.665-0.896, p < 0.001). In conclusion, TECH accurately estimated the average intakes of energy and selected foods and thus has the potential to be a useful tool for dietary studies in pre-school children, for example obesity prevention trials.

Abstract
BACKGROUND Lack of uniformity in outcome measures used in evaluations of childhood obesity treatment interventions can impede the ability to assess effectiveness and limits comparisons across trials. OBJECTIVE To identify and appraise outcome measures to produce a framework of recommended measures for use in evaluations of childhood obesity treatment interventions. DATA SOURCES Eleven electronic databases were searched between August and December 2011, including MEDLINE; MEDLINE In-Process and Other Non-Indexed Citations; EMBASE; PsycINFO; Health Management Information Consortium (HMIC); Allied and Complementary Medicine Database (AMED); Global Health, Maternity and Infant Care (all Ovid); Cumulative Index to Nursing and Allied Health Literature (CINAHL) (EBSCOhost); Science Citation Index (SCI) [Web of Science (WoS)]; and The Cochrane Library (Wiley) - from the date of inception, with no language restrictions. This was supported by review of relevant grey literature and trial databases. REVIEW METHODS Two searches were conducted to identify (1) outcome measures and corresponding citations used in published childhood obesity treatment evaluations and (2) manuscripts describing the development and/or evaluation of the outcome measures used in the childhood intervention obesity evaluations. Search 1 search strategy (review of trials) was modelled on elements of a review by Luttikhuis et al. (Oude Luttikhuis H, Baur L, Jansen H, Shrewsbury VA, O'Malley C, Stolk RP, et al. Interventions for treating obesity in children. Cochrane Database Syst Rev 2009;1:CD001872). Search 2 strategy (methodology papers) was built on Terwee et al.'s search filter (Terwee CB, Jansma EP, Riphagen II, de Vet HCW. Development of a methodological PubMed search filter for finding studies on measurement properties of measurement instruments. Qual Life Res 2009;18:1115-23). Eligible papers were appraised for quality initially by the internal project team. This was followed by an external appraisal by expert collaborators in order to agree which outcome measures should be recommended for the Childhood obesity Outcomes Review (CoOR) outcome measures framework. RESULTS Three hundred and seventy-nine manuscripts describing 180 outcome measures met eligibility criteria. Appraisal of these resulted in the recommendation of 36 measures for the CoOR outcome measures framework. Recommended primary outcome measures were body mass index (BMI) and dual-energy X-ray absorptiometry (DXA). Experts did not advocate any self-reported measures where objective measurement was possible (e.g. physical activity). Physiological outcomes hold potential to be primary outcomes, as they are indicators of cardiovascular health, but without evidence of what constitutes a minimally importance difference they have remained as secondary outcomes (although the corresponding lack of evidence for BMI and DXA is acknowledged). No preference-based quality-of-life measures were identified that would enable economic evaluation via calculation of quality-adjusted life-years. Few measures reported evaluating responsiveness. LIMITATIONS Proposed recommended measures are fit for use as outcome measures within studies that evaluate childhood obesity treatment evaluations specifically. These may or may not be suitable for other study designs, and some excluded measures may be more suitable in other study designs. CONCLUSIONS The CoOR outcome measures framework provides clear guidance of recommended primary and secondary outcome measures. This will enhance comparability between treatment evaluations and ensure that appropriate measures are being used. Where possible, future work should focus on modification and evaluation of existing measures rather than development of tools de nova. In addition, it is recommended that a similar outcome measures framework is produced to support evaluation of adult obesity programmes.

Abstract
BACKGROUND Methods for the assessment of changes in dietary intake across the life course are underdeveloped. METHODS We demonstrate the use of linear-spline multilevel models to summarize energy-intake trajectories through childhood and adolescence and their application as exposures, outcomes, or mediators. The Avon Longitudinal Study of Parents and Children assessed children's dietary intake several times between ages 3 and 13 years, using both food frequency questionnaires (FFQs) and 3-day food diaries. We estimated energy-intake trajectories for 12,032 children using linear-spline multilevel models. We then assessed the associations of these trajectories with maternal body mass index (BMI), and later offspring BMI, and also their role in mediating the relation between maternal and offspring BMIs. RESULTS Models estimated average and individual energy intake at 3 years, and linear changes in energy intake from age 3 to 7 years and from age 7 to 13 years. By including the exposure (in this example, maternal BMI) in the multilevel model, we were able to estimate the average energy-intake trajectories across levels of the exposure. When energy-intake trajectories are the exposure for a later outcome (in this case offspring BMI) or a mediator (between maternal and offspring BMI), results were similar, whether using a two-step process (exporting individual-level intercepts and slopes from multilevel models and using these in linear regression/path analysis), or a single-step process (multivariate multilevel models). Trajectories were similar when FFQs and food diaries were assessed either separately, or when combined into one model. CONCLUSIONS Linear-spline multilevel models provide useful summaries of trajectories of dietary intake that can be used as an exposure, outcome, or mediator.

Abstract
BACKGROUND & AIMS Little is known about the validity of repeated 24-h dietary recalls (24-HDR) as a measure of total energy intake (EI) in young children. This study aimed to evaluate the validity of proxy-reported EI by comparison with total energy expenditure (TEE) measured by the doubly labeled water (DLW) technique. METHODS The agreement between EI and TEE was investigated in 36 (47.2% boys) children aged 4-10 years from Belgium and Spain using subgroup analyses and Bland-Altman plots. Low-energy-reporters (LER), adequate-energy-reporters (AER) and high-energy-reporters (HER) were defined from the ratio of EI over TEE by application of age- and sex-specific cut-off values. RESULTS There was good agreement between means of EI (1500 kcal/day) and TEE (1523 kcal/day) at group level though in single children, i.e. at the individual level, large differences were observed. Almost perfect agreement between EI and TEE was observed in thin/normal weight children (EI: 1511 kcal/day; TEE: 1513 kcal/day). Even in overweight/obese children the mean difference between EI and TEE was only -86 kcal/day. Among the participants, 28 (78%) were classified as AER, five (14%) as HER and three (8%) as LER. CONCLUSION Two proxy-reported 24-HDRs were found to be a valid instrument to assess EI on group level but not on the individual level.

Abstract
The prevalence of childhood overweight and obesity has been shown to differ among regions, including rural–urban regional differences within nations. This study obtained simultaneous accelerometry-derived physical activity, 24 h activity, and food records to clarify the potential contributing factors to rural–urban differences in childhood overweight and obesity in Japan. Sixth-grade children (n = 227, 11–12 years old) from two urban elementary schools in Kyoto and four rural elementary schools in Tohoku participated in the study. The children were instructed to wear a pedometer that included a uniaxial accelerometer and, assisted by their parents, keep minute-by-minute 24 h activity and food records. For 12 children, the total energy expenditure was measured by the doubly labeled water method that was used to correct the Lifecorder-predicted activity energy expenditure and physical activity level. The overweight and obesity prevalence was significantly higher in rural than in urban children. The number of steps per day, activity energy expenditure, physical activity level, and duration of walking to school were significantly lower in rural than in urban children. In contrast, the reported energy intake did not differ significantly between the regions. The physical activity and duration of the walk to school were significantly correlated with body mass index. Rural children had a higher prevalence of overweight and obesity, and this may be at least partly caused by lower physical activity, especially less time spent walking to school, than urban children.

[PMID: 22957217 PMCID: PMC3431099 DOI: 10.1155/2012/247389] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2012] [Accepted: 06/28/2012] [Indexed: 11/18/2022] Open
Abstract
The objective was to evaluate overweight and obese children's ability to report reproducible and valid estimates of energy intake (EI) by using digital camera food records (FR) during a 2-year study, compared with objectively measured total energy expenditure (TEE). Seventy-three overweight/obese children, aged 8-12 years at inclusion, kept FR with the help of digital cameras for 16 days in total, on 7 occasions during a 2-year period. On the same days, their TEE was registered with SenseWear Armband (SWA). The children underestimated their EI by -2.8 (2.4) MJ/d on the first assessment occasion (95% CI: -3.3, -2.3). Reporting accuracy did not differ between the 7 assessment occasions (P = 0.15). Variables negatively associated with reporting accuracy relative to TEE were increased age (95% CI: -0.07, -0.01) and BMI z-score (95% CI: -0.18, -0.06). Further, reporting accuracy relative to TEE was lower for girls than boys (95% CI: -0.14, -0.01) and on weekdays compared with weekend days (95% CI: -0.08, -0.001). In conclusion, overweight and obese children were able to report their EI using a digital camera FR with good reproducibility over a 2-year period, even though their EI was underestimated compared with objectively measured TEE.

Abstract
OBJECTIVE The objective of this study was to assess the effects of a maintenance programme (monthly newsletters vs. monthly group classes and telephone behavioural sessions) on obesity and metabolic disease risk at 1 year in overweight minority adolescents. METHODS After a 4-month nutrition and strength training intervention, 53 overweight Latino and African-American adolescents (15.4 ± 1.1 years) were randomized into one of two maintenance groups for 8 months: monthly newsletters (n = 23) or group classes (n = 30; monthly classes + individualized behavioural telephone sessions). The following outcomes were measured at months 4 (immediately following the intense intervention) and 12: height, weight, blood pressure, body composition via BodPod™ (Life Measurement Instruments, Concord, CA, USA), lipids and glucose/insulin indices via frequently sampled intravenous glucose tolerance test. RESULTS There were no significant group by time interactions for any of the health outcomes. There were significant time effects in several outcomes for both groups from months 4 to 12: bench press and leg press decreased by 5% and 14%, respectively (P = 0.004 & P = 0.01), fasting insulin and acute insulin response decreased by 26% and 16%, respectively (P < 0.001 & P = 0.046); while high-density lipoprotein cholesterol and insulin sensitivity improved by 5% and 14% (P = 0.042 & P = 0.039). CONCLUSIONS Newsletters as opposed to group classes may suffice as follow-up maintenance programmes to decrease type 2 diabetes and cardiovascular risk in overweight minority adolescents.

Abstract
AbstractObjectiveTo examine: (i) children's food intake and adherence to both Canada's Food Guide for Healthy Eating and Dietary Reference Intakes; and (ii) the social and demographic factors related to children's food intake.DesignA cross-sectional study.SettingData were obtained through the Quebec Longitudinal Study of Child Development 1998–2010, a representative sample (n 2103) of children born in 1998 in the province of Quebec, Canada. Information on energy, macronutrient and food consumption was derived from responses to a 24 h dietary recall interview addressed to children's mothers and day-care staff when the children were 4 years old.SubjectsA total of 1549 children aged 4 years who participated in a nutritional sub-study.ResultsThe mean daily total energy intake was 6360 kJ (1520 kcal) for girls and 6916 kJ (1653 kcal) for boys. For boys and girls alike, energy intake was comprised of approximately 54 % carbohydrates, 31 % fats and 15 % proteins. The mean number of servings consumed from each of the four essential food groups closely approached the dietary recommendations made by Canada's Food Guide for Healthy Eating; however, <2 % of the children in the present study actually met the full dietary guidelines. The dietary intake of pre-school children was associated with socio-economic and demographic factors, most notably mother's level of education, mother's immigrant status and sex of the child.ConclusionsDiet-related disparities associated with socio-economic and demographic factors exist from as early as 4 years of age.

Abstract
Measuring dietary intake in children enables the assessment of nutritional adequacy of individuals and groups and can provide information about nutrients, including energy, food, and eating habits. The aim of this review was to determine which dietary assessment method(s) provide a valid and accurate estimate of energy intake by comparison with the gold standard measure, doubly labeled water (DLW). English-language articles published between 1973 and 2009 and available from common nutrition databases were retrieved. Studies were included if the subjects were children birth to age 18 years and used the DLW technique to validate reported energy intake by any other dietary assessment method. The review identified 15 cross-sectional studies, with a variety of comparative dietary assessment methods. These included a total of 664 children, with the majority having <30 participants. The majority of dietary assessment method validation studies indicated a degree of misreporting, with only eight studies identifying this to a significant level (P<0.05) compared to DLW estimated energy intake. Under-reporting by food records varied from 19% to 41% (n=5 studies) with over-reporting most often associated with 24-hour recalls (7% to 11%, n=4), diet history (9% to 14%, n=3), and food frequency questionnaires (2% to 59%, n=2). This review suggested that the 24-hour multiple pass recall conducted over at least a 3-day period that includes weekdays and weekend days and uses parents as proxy reporters is the most accurate method to estimate total energy intake in children aged 4 to 11 years, compared to total energy expenditure measured by DLW. Weighed food records provided the best estimate for younger children aged 0.5 to 4 years, whereas the diet history provided better estimates for adolescents aged≥16 years. Further research is needed in this area to substantiate findings and improve estimates of total energy expenditure in children and adolescents.

Abstract
OBJECTIVE To validate an FFQ designed to estimate energy intake in children against doubly labelled water (DLW). To investigate how quality control and standard beverage portion sizes affect the validity of the FFQ. DESIGN Thirty healthy children, aged 4-6 years, participated. Total energy expenditure (EE) was measured by the DLW method during an observation period of 15 d. At the end of this period parents filled out an FFQ designed to assess the child's habitual energy intake (EI) of the preceding four weeks. SETTING Validation study in The Netherlands. SUBJECTS Thirty healthy children (fifteen boys and fifteen girls), aged 4-6 years. RESULTS Mean EI (6117 (sd 1025) kJ/d) did not differ significantly from mean EE (6286 (sd 971) kJ/d; P = 0·15); the mean EI:EE ratio was 0·98. The Pearson correlation coefficient between EI and EE was 0·62. The Bland-Altman plot showed no systematic bias and a constant bias close to zero. Less intensive quality control of the FFQ maintained the mean EI:EE ratio and decreased the correlation slightly. Using standard instead of individually measured beverage portion sizes decreased the mean EI:EE ratio, but maintained the correlation. CONCLUSIONS It can be concluded that the developed FFQ is a valid instrument to estimate mean energy intake in a group of 4- to 6-year-old children and performs reasonably well to rank the subjects with respect to energy intake. It is therefore a useful instrument to estimate energy intake in children in surveys and epidemiological studies in The Netherlands.

Abstract
Data from a study concerning retention interval and school-meal observation on children's dietary recalls were used to investigate relationships of social desirability score (SDS) and body mass index percentile (BMI%) to recall accuracy for energy for observed (n = 327) children, and to reported energy for observed and unobserved (n = 152) children. Report rates (reported/observed) correlated negatively with SDS and BMI%. Correspondence rates (correctly reported/observed) correlated negatively with SDS. Inflation ratios (overreported/observed) correlated negatively with BMI%. The relationship between reported energy and each of SDS and BMI% did not depend on observation status. Studies utilizing children's dietary recalls should assess SDS and BMI%.

Abstract
BACKGROUND Water is an essential nutrient, but recommendations for total water requirements only emerged in 2005, in the context of estimated average population targets in the Dietary Reference Intakes (DRIs) for US and Canadian societies. OBJECTIVE To assess total daily water acquisition, and the contribution of water acquired from all possible sources, among Guatemalan children. METHODS A total of 449 urban Guatemalan schoolchildren, aged 8 to 11 years, evenly divided between two socioeconomic strata, completed a 1-day pictorial registry of all foods and beverages consumed. Estimated energy intake, total water intake, and the contributions of water from drinking water, beverages, intrinsic and extrinsic water in foods, and the oxidation of macronutrients were assessed. RESULTS The contribution of water from the examined water sources was 8% for drinking water, 49% for beverages, 29% for all foods, and 14% for metabolism of macronutrients, with only slight variance across sexes and social class. The average total daily water acquisition was 1,841 +/- 572 mL for boys and 1,834 +/- 484 mL for girls, which fall short of the North American DRI recommendations of 2.4 and 2.1 L, respectively There was correspondingly lower average consumption of dietary liquids. CONCLUSIONS Foods play an important role in the acquisition of water from their hydration and metabolic oxidation, contributing 43.8% of the daily supply to these children. There is still a calculated shortfall of daily water acquisition, as compared with the DRI recommendations, which could be overcome by greater intake of plain water and low-energy fresh produce.

Abstract
Schools are integral settings in which children can participate in moderate and vigorous physical activity. This study reports on the relationship between playground characteristics and child activity levels using a combination of quantitative and qualitative methods. The aim of the study is to increase understanding of how children respond to their school playground environments. Twenty-three primary schools located in a predominantly low socio-economic area of Melbourne, Australia were involved. SOPLAY (System for Observing Play and Leisure Activity in Youth) was administered in all 23 schools to measure the levels of student physical activity and playground environmental factors such as equipment provision. In 12 of the 23 schools, a sample of 9-11-year-old students participated in focus group discussions exploring perceptions of their school playgrounds using a photo ordering technique. A larger proportion of students participated in VPA when loose equipment (60% vs. 52%; p<0.001) and teacher supervision (62% vs. 52%; p<0.001) were present in activity settings, compared to when they were unavailable. Fixed play equipment and bitumen with court/play-line markings were seen by children as settings inviting active play but only had the greatest impact on moderate activity (fixed play equipment: 35% vs. 20%, p<0.001; court markings/goals: 62% vs. 52%, p<0.001; play-line markings: 25% vs. 20%, p=0.04). The mixed method design provided a greater understanding of the potential influence of environmental characteristics on children's lunch time activity levels and their perceptions of play areas. The findings indicate that relatively simple changes such as the provision of loose equipment, painting of court and play-line markings, and increased teacher presence on the playground, are likely to provide opportunities for increased physical activity.

Abstract
The incidence of distal forearm fractures peaks during the adolescent growth spurt, but the structural basis for this is unclear. Thus, we studied healthy 6- to 21-yr-old girls (n = 66) and boys (n = 61) using high-resolution pQCT (voxel size, 82 microm) at the distal radius. Subjects were classified into five groups by bone-age: group I (prepuberty, 6-8 yr), group II (early puberty, 9-11 yr), group III (midpuberty, 12-14 yr), group IV (late puberty, 15-17 yr), and group V (postpuberty, 18-21 yr). Compared with group I, trabecular parameters (bone volume fraction, trabecular number, and thickness) did not change in girls but increased in boys from late puberty onward. Cortical thickness and density decreased from pre- to midpuberty in girls but were unchanged in boys, before rising to higher levels at the end of puberty in both sexes. Total bone strength, assessed using microfinite element models, increased linearly across bone age groups in both sexes, with boys showing greater bone strength than girls after midpuberty. The proportion of load borne by cortical bone, and the ratio of cortical to trabecular bone volume, decreased transiently during mid- to late puberty in both sexes, with apparent cortical porosity peaking during this time. This mirrors the incidence of distal forearm fractures in prior studies. We conclude that regional deficits in cortical bone may underlie the adolescent peak in forearm fractures. Whether these deficits are more severe in children who sustain forearm fractures or persist into later life warrants further study.

Abstract
OBJECTIVE The Mediterranean diet is considered one of the healthiest dietary models. Recent changes in the actual Mediterranean diet include a reduction in energy intake and a higher consumption of foods with low nutrient density (e.g. soft drinks, candy, sweets, etc.). In Spain, in association with cultural and lifestyle changes, there has been a reduction in the intake of antioxidants and vitamins, an increase in the proportion of SFA and a decrease in the consumption of fibre, among other changes. Children and adolescents may be the age groups with the most deteriorated Mediterranean diet. The current paper presents the results of applying the Mediterranean Diet Quality Index for children and adolescents (KIDMED) to a large sample of Spanish schoolchildren. DESIGN Data from questionnaires were used to calculate the KIDMED index. SETTING Granada, Southern Spain. SUBJECTS Schoolchildren (n 3190) aged 8-16 years. RESULTS Among the 8-10-year-olds, the KIDMED index classification was 'good' in 48.6% of the population, 'average' in 49.5% and 'poor' in 1.6%. Among the 10-16-year-olds, the KIDMED index classification was good in 46.9% of the population, average in 51.1% and poor in 2.0%. CONCLUSIONS The nutritional behaviour of the present population of schoolchildren is similar to that found in the earlier KIDMED study.

Abstract
This pilot study investigated body mass index (BMI; calculated as kg/m(2)), sex, interview protocol, and children's accuracy for reporting kilocalories. Forty 4th-grade children (20 low-BMI: >or=5th and <50th percentiles, 10 boys, 15 African American; 20 high-BMI: >or=85th percentile, 10 boys, 15 African American) were observed eating school meals (breakfast, lunch) and interviewed either that evening about the prior 24 hours or the next morning about the previous day, with 10 low-BMI (5 boys) and 10 high-BMI (5 boys) children per interview protocol. Five kilocalorie variables were analyzed using separate four-factor (BMI group, sex, race, interview protocol) analyses of variance. No effects were found for reported or matched kilocalories. More kilocalories were observed (P<0.02) and omitted (P<0.05) by high-BMI than low-BMI children. For intruded kilocalories, means were smaller (better) for high-BMI girls than high-BMI boys, but larger for low-BMI girls than low-BMI boys (interaction P<0.04); low-BMI girls intruded the most while high-BMI girls intruded the least. For interview protocol, omitted and intruded kilocalories were higher (worse), although not significantly so (P values <0.11), for interviews about the previous day than the prior 24 hours. These results illuminate relations of BMI, sex, interview protocol, and children's reporting accuracy, and are consistent with results concerning BMI and sex from studies with adults.

Abstract
OBJECTIVE To evaluate energy balance and physical activity in obese preschool children attending day-care centres. DESIGN Cross-sectional study. SUBJECTS Twenty-four 3-5 years old obese children selected at random from four different day-care centres in Santiago City, Chile. Total energy expenditure (TEE) was measured by doubly labelled water and physical activity as recorded by TRITRAC R3D motion sensor. Energy intake was assessed by measuring food intake while at the centre, along with the recording of additional food intake in the home. RESULTS Obese children had a 5.4% higher weighed energy intake than their energy requirements 2001. Energy intake during the week was 7716+/-1092 kJ/day and 7401+/-1023 kJ/day in boys and girls, respectively. Minimal activity was higher in the day-care centres (62%) compared to 52% during the weekend at home. Light activity was higher during the weekend at home than during the week (25 versus 20%), but moderate-intense activity was similar (3-5%). CONCLUSIONS Reduction in dietary energy provided at the day-care centres helps to balance energy requirements during the week. Obese children had marked sedentary characteristics with regards to physical activity, although children are more active at home in weekends. This situation suggests that educators and parents need to improve children's physical activity levels and nutrition habits.

Abstract
This secondary analysis investigated the influence of body mass index (BMI) category and sex on reporting accuracy during multiple 24-hour dietary recalls. On three occasions, each of 79 children (40 girls) was observed eating school meals and interviewed the next morning about the previous day's intake, with ≥ 25 days between any two consecutive occasions for a child. Using age/sex BMI percentiles, we categorized 48 children as healthy weight (≥ 5(th) percentile <85(th)), 14 as at risk of overweight (≥ 85(th) percentile <95(th)), and 17 as overweight (≥95(th) percentile). A repeated-measures analysis was conducted for each of five outcomes (number of items observed eaten, number of items reported eaten, omission rate, intrusion rate, total inaccuracy). For items observed, BMI category x trial was marginally significant (P=0.079); over trials, this outcome was stable for healthy-weight children, decreased and stabilized for at-risk-of-overweight children, and was stable and decreased for overweight children. This outcome was greatest for overweight children and least for healthy-weight children (P=0.015). For items reported, no significant effects were found. For omission rate (P=0.028) and intrusion rate (P=0.083), BMI category x trial was significant and marginally significant; over trials, both decreased for healthy-weight children, decreased and stabilized for at-risk-of-overweight children, and increased and stabilized for overweight children. Total inaccuracy decreased slightly over trials (P=0.076); this outcome was greater for boys than for girls (P=0.049). Results suggest that children's dietary reporting accuracy over multiple recalls varies by BMI category. Validation studies with adequate samples for each BMI category, sex, and race are needed.

Abstract
OBJECTIVE To determine the extent of misreporting of energy intake (EI) and its anthropometric, demographic, and psychosocial correlates in a bi-racial cohort of young women. RESEARCH METHODS AND PROCEDURES This was a cross-sectional study of 60 black and 60 white young women, 18 to 21 years old, enrolled in a longitudinal study. Total energy expenditure was assessed using doubly labeled water. Self-reported EI was obtained from 3-day food records. BMI was computed from height and weight. Fat mass was assessed by DXA. Multivariate analyses examined racial differences on the extent of misreporting and its effect on other potential correlates of misreporting. Race-specific step-wise linear regression analysis was performed to examine the effect of BMI, parental education, and drive for thinness on misreporting of EI. RESULTS More white women tended to under-report EI than black women (22% vs. 13%, p = 0.07). In black women, under-reporting was significantly (p = 0.01) associated with drive for thinness score but was only marginally (p = 0.1) associated with BMI. Each point increase in drive for thinness score was associated with under-reporting by 40 kcal/d. In white women, under-reporting was significantly (p = 0.03) associated with higher parental education by 440 kcal/d and also only marginally (p = 0.09) with BMI. DISCUSSION This tendency for under-reporting of EI limits the use of self-reported EI in studying energy balance in free-living subjects. Most black and almost all white women in their late teens significantly under-reported their EI, whereas under-reporting was not as evident among lean young black women.

Abstract
OBJETIVO: Determinar a relação entre diferentes índices de atividade física e preditores de adiposidade em adolescentes de ambos os sexos. MÉTODOS: Foram avaliadas 111 crianças (57 meninos e 54 meninas), com idade média de 11,62 ± 0,72. Como preditores de adiposidade foram determinados o IMC, percentagem de gordura corporal e a relação cintura/quadril (RCQ). Quanto aos indicadores de atividade física, calcularam-se o gasto energético total (GET), nível de atividade física habitual (NAFH), nível de atividade física (NAF) e gasto energético com atividade física (GEat) através do questionário de Bouchard e, para a taxa metabólica basal (TMB), a equação de Schofield-HW. RESULTADOS: A amostra apresentou diferenças significativas entre os sexos para idade, % de gordura corporal, RCQ, NAFH, NAF, TMB com p < 0,05. Para os meninos o GET, NAF, TMB e GEat apresentaram correlação significativa com o IMC (r = 0,86; r = 0,70; r = 0,91; r = 0,78) e % de gordura (r = 0,78; r = 0,61; r = 0,90; r = 0,70) com p < 0,01, respectivamente, e o GET, TMB, GEat apresentaram correlação significativa com o RCQ (r = 0,28; r = 0,45 e r = 0,28) com p < 0,05. Para as meninas o GET, NAF, TMB, GEat apresentaram valores significativos com o IMC (r = 0,86; r = 0,82; r = 0,78; r = 0,85); em % de gordura todos os indicadores GET, NAFH, NAF, TMB e GEat foram significativos (r = 0,73; r = -0,29; r = 0,66; r = 0,74; r = 0,70) com p < 0,05. CONCLUSÃO: Os diferentes indicadores de nível de atividade física apresentaram significativa correlação com os preditores de adiposidade com exceção do RCQ para as meninas. O aumento da massa corporal demonstrou relação significância com o aumento do dispêndio energético em função da maior necessidade de energia para movimentar o corpo.

Abstract
BACKGROUND The Block98 food frequency questionnaire (FFQ) has been validated for dietary assessment of usual intakes in adults, but not in children. OBJECTIVE To assess the agreement of the Block98 FFQ and 3-day diet records for measuring dietary intakes in young girls. SUBJECTS/SETTING Healthy 4- to 9-year-old girls (N=61; 6.5+/-1.6 years) were recruited from the Athens/Clarke county area in Georgia. DESIGN Dietary intakes were measured using the Block98 FFQ and 3-day diet records, with nutrient analysis of the 3-day diet records conducted using the Food Processor computer program (ESHA; version 7.21, 1998, ESHA Research, Salem, OR). The Block98 FFQ was completed by a trained interviewer and parent, with input from the child, if able. Food models and portion size pictures were used to increase reporting accuracy. STATISTICAL ANALYSIS Paired sample t tests and simple regression were conducted to determine whether the two diet instruments reported similar values for energy and macronutrients. RESULTS Block98 FFQ overestimated intakes from 3-day diet records for energy (2,180+/-692 vs 1,749+/-328 kcal), protein (68.3+/-25.9 vs 57.9+/-14.8 g/day), carbohydrate (298.7+/-97.0 vs 244.7+/-46.1 g/day) and fat (83.6+/-30.5 vs 62.3+/-14.7 g/day) (P<.05). Furthermore, the nutrients assessed using the two different methods were only moderately correlated (range: r=0.40 to 0.55). APPLICATIONS/CONCLUSIONS The Block98 FFQ agreed weakly to moderately with the 3-day diet records, and resulted in consistently higher intakes of all nutrients. These findings suggest that additional work is needed to develop a FFQ that reflects young children's energy and macronutrient intakes.
