Variability in sleep disturbance, physical activity and quality of life by level of depressive symptoms in women with Type 2 diabetes.

AIMS: To examine (1) the prevalence of depressive symptoms in women with Type 2 diabetes, (2) the associations between depressive symptoms and the following dependent variables: sleep disturbance; physical activity; physical health-related; and global quality of life, and (3) the potential moderating effects of antidepressants and optimism on the relationship between depressive symptoms and dependent variables. METHODS: Participants in the Women's Health Initiative who had Type 2 diabetes and data on depressive symptoms (N=8895) were included in the analyses. In multivariable linear regression models controlling for sociodemographic, medical and psychosocial covariates, we examined the main effect of depressive symptoms, as well as the interactions between depressive symptoms and antidepressant use, and between depressive symptoms and optimism, on sleep disturbance, physical activity, physical health-related quality of life; and global quality of life. RESULTS: In all, 16% of women with Type 2 diabetes reported elevated depressive symptoms. In multivariable analyses, women with depressive symptoms had greater sleep disturbance (P<0.0001) and lower global quality of life (P<.0001). We found evidence of significant statistical interaction in the models for quality-of-life outcomes: the increased risk of poor physical health-related quality of life associated with antidepressant use was stronger in women without vs with depressive symptoms, and the association between greater optimism and higher global quality of life was stronger in women with vs without depressive symptoms. CONCLUSIONS: To improve health behaviours and quality of life in women with Type 2 diabetes, sociodemographic and medical characteristics may identify at-risk populations, while psychosocial factors including depression and optimism may be important targets for non-pharmacological intervention.

Association of Dynamics in Lean and Fat Mass Measures with Mortality in Frail Older Women.

OBJECTIVE: The relationship between body composition and mortality in frail older people is unclear. We used dual-x-ray absorptiometry (DXA) data to examine the association between dynamics in whole-body composition and appendicular (4 limbs) and central (trunk) compartments and all-cause mortality in frail older women. DESIGN: Prospective study with up to 19 years of follow up. SETTING: Community dwelling older (≥65) women. PARTICIPANTS: 876 frail older participants of the Women's Health Initiative Observational Study with a single measure of body composition and 581 participants with two measures. MEASUREMENTS: Frailty was determined using modified Fried's criteria. All-cause mortality hazard was modeled as a function of static (single-occasion) or dynamic changes (difference between two time points) in body composition using Cox regression. RESULTS: Analyses adjusted for age, ethnicity, income, smoking, cardiovascular disease, diabetes, stroke, number of frailty criteria and whole-body lean mass showed progressively decreased rates of mortality in women with higher appendicular fat mass (FM) (P for trend=0.01), higher trunk FM (P for trend=0.03) and higher whole-body FM (P for trend=0.01). The hazard rate ratio for participants with more than a 5% decline in FM between two time points was 1.91; 1.67 and 1.71 for appendicular, trunk and whole-body compartment respectively as compared to women with relatively stable adiposity (p<0.05 for all). Dynamics of more than 5% in lean mass were not associated with mortality. CONCLUSION: Low body fat or a pronounced decline in adiposity is associated with increased risks of mortality in frail older women. These results indicate a need to re-evaluate healthy weight in persons with frailty. .

Study design and baseline description of the BMI2 trial: reducing paediatric obesity in primary care practices.

OBJECTIVES: This study will test the efficacy of motivational interviewing (MI) conducted by primary care providers and dieticians among children ages 2-8 years old with a body mass index (BMI) ≥ 85th and ≤ 97th percentile. METHODS: Forty-two practices from the American Academy of Pediatrics, Pediatric Research in Office Settings Network were assigned to one of three groups. Group 1 (usual care) measures BMI percentile at baseline, and at 1- and 2-year follow-ups and receives standard health education materials. Group 2 providers deliver three proactive MI counselling sessions with a parent of the index child in Year 1 and one additional 'booster' visit in Year 2. Group 3 adds six MI counselling sessions from a trained dietician. The primary outcome is the child's BMI percentile at 2-year follow-up. Secondary outcomes include parent report of the child's screen time, physical activity, intake of fruits and vegetables, and sugar-sweetened beverages. RESULTS: We enrolled 633 eligible children whose mean BMI percentile was 92.0 and mean age of 5.1. The cohort was 57% female. Almost 70% of parents reported a household income of ≥ $40,000 per year, and 39% had at least a college education. The cohort was 63% white, 23% Hispanic, 7% black and 7% Asian. Parent self-reported confidence that their child will achieve a healthy weight was on average an 8 (out of 10). CONCLUSION: To date, several aspects of the study can inform similar efforts including our ability to use volunteer clinicians to recruit participants and their willingness to dedicate their time, without pay, to receive training in MI.

Effect of long term low-fat dietary intervention on change in hemostatic factors: results from the Women's Health Initiative.

Low-fat diet may play a role in prevention of cardiovascular disease (CVD) by altering the levels of hemostatic factors. There are yet limited data on the effects of low-fat diet on the circulating levels of these factors and existing studies are limited by small sample size and short duration of follow-up. We conducted an analysis in a subset of women (active arm = 723; control arm = 1036) within the Women's Health Initiative Dietary Modification Trial to investigate the long term effect of a low-fat diet on circulating levels of fibrinogen, factor VII concentration and factor VII activity among postmenopausal women aged 50-79 years. Using linear mixed effects model with random intercept and data from three follow-up visits (years 1, 3 and 6) we evaluated the change in each factor over time. Overall, the changes in these factors were small (less than 5%) in both the arms of the trials at the end of intervention and there was no significant difference in mean change between the two arms. Our results indicate that the low-fat dietary intervention was not associated with significant changes in hemostatic factors among postmenopausal women.

Predictors of adherence in the Women's Health Initiative Calcium and Vitamin D Trial.

The authors analyzed data from the Women's Health Initiative (WHI) Calcium and Vitamin D Supplementation Trial (CaD) to learn more about factors affecting adherence to clinical trial study pills (both active and placebo). Most participants (36,282 postmenopausal women aged 50-79 years) enrolled in CaD 1 year after joining either a hormone trial or the dietary modification trial of WHI. The WHI researchers measured adherence to study pills by weighing the amount of remaining pills at an annual study visit; adherence was primarily defined as taking > or = 80% of the pills. The authors in this study examined a number of behavioral, demographic, procedural, and treatment variables for association with study pill adherence. They found that relatively simple procedures (ie, phone contact early in the study [4 weeks post randomization] and direct social contact) later in the trial may improve adherence. Also, at baseline, past pill-use experiences, personal supplement use, and relevant symptoms may be predictive of adherence in a supplement trial.

Age group differences in diet and physical activity-related behaviors among rural men and women.

OBJECTIVES: Age group variations in dietary intake and physical activity have been noted in large epidemiologic studies. In this study, specific measures of behavioral strategies add depth to our understanding of these variations and can contribute to the design of effective behavioral interventions. DESIGN: Cross-sectional, behavioral epidemiologic study. SETTING: Rural Midwestern US. PARTICIPANTS: 407 adults. MEASUREMENTS: Measures included dietary intake, physical activity, body mass index (BMI), and specific behavioral strategies related to diet and physical activity. RESULTS: Use of most strategies related to diet increased across age groups, which was consistent with declining caloric intake and a decline in the proportion of total caloric intake from fat. The same patterns were not found with regard to physical activity. Greater use of diet-related strategies was noted in the oldest age groups compared to the others even though BMI was lower. CONCLUSIONS: In the oldest age group at least, strategy use may be more related to attempts to control health conditions than body weight. The findings provide a unique perspective on age group differences in diet and physical activity behavior. Longitudinal tracking of these specific behaviors and their measurement in other populations is warranted.

A brief motivational intervention to improve dietary adherence in adolescents. The Dietary Intervention Study in Children (DISC) Research Group.

Motivational interviewing offers health care professionals a potentially effective strategy for increasing a patient's readiness to change health behaviors. Recently, elements of motivational interviewing and the stages of change model have been simplified and adapted for use with patients in brief clinical encounters. This paper describes in detail a brief motivational intervention model to improve and renew dietary adherence with adolescents in the Dietary Intervention Study in Children (DISC). DISC is a randomized, multi-center clinical trial assessing the efficacy and safety of lowering dietary fat to decrease low-density lipoprotein cholesterol in high-risk children. In the first 3 years of follow-up covering ages 8-13, intervention participants (n = 334) were exposed to a family-based group intervention approach to change dietary choices. To address adherence and retention obstacles as participants moved into adolescence (age 13-17), an individual-level motivational intervention was implemented. The DISC motivational intervention integrates several intervention models: stages of change, motivational interviewing, brief negotiation and behavioral self-management. A preliminary test of the intervention model suggests that it was acceptable to the participants, popular with interventionists and appeared to be an age-appropriate shift from a family-based intervention model.

Effect of a ketoacid-aminoacid-supplemented very low protein diet on the progression of advanced renal disease: a reanalysis of the MDRD feasibility study.

BACKGROUND: We reanalyzed the data of the Modification of Diet in Renal Disease (MDRD) feasibility study to ascertain the effects of ketoacid- and aminoacid-supplemented very low protein diets. METHODS: Sixty-six patients with advanced renal disease (Study B, baseline glomerular filtration rate (GFR) 7.5-24 ml/min/1.73 m2) were randomly assigned to a low protein diet (L, 0.575 g/kg/d), or a very low protein diet (0.28 g/kg/d) supplemented either with a ketoacid-aminoacid mixture (diet K) or with a mixture of essential aminoacids (diet J). Thirty patients with moderate renal disease (Study A, baseline GFR 25-80 ml/min/1.73 m2) were randomly assigned to a usual protein diet (M, 1.2 g/kg/d), diet L, or diet K. Mean follow-up was 14 months. RESULTS: In Study B, GFR decline differed among the three diets (p = 0.028). Pairwise comparisons showed that the mean +/- SE GFR decline in ml/min/mo in diet K [-0.250+/-0.072] was slower than in diet J [-0.533+/-0.074] (p = 0.008) despite similar achieved protein intakes. The mean GFR decline in diet L [-0.394+/-0.068] was intermediate between, and did not differ significantly from the rates of decline in the other two groups. In Study A, consistent with a hemodynamic effect, the mean GFR decline varied directly with the reduction in protein intake in diets M, L and K (p = 0.028) during the first four months of follow-up, but thereafter did not differ among the diet groups (p = 0.76). CONCLUSION: The study suggests that supplementation of a very low protein diet with the ketoacid-aminoacid mixture used in this feasibility study slowed the progression of advanced renal disease more than supplementation with an amino acid mixture.

Maternal acceptability of a dietary intervention designed to lower children's intake of saturated fat and cholesterol: the Dietary Intervention Study in Children (DISC).

OBJECTIVE: This report examined the acceptability to mothers of a dietary educational and behavioral intervention for preadolescent children with elevated levels of serum low-density lipoprotein cholesterol (LDL-C) who were enrolled in the Dietary Intervention Study in Children (DISC). DESIGN: DISC is a randomized, controlled clinical trial. Subjects were randomly assigned to either an intervention or usual-care (control) group. SUBJECTS/SETTING: To be eligible for the study, participants were required to have the average of 2 fasting LDL-C values fall between the 80th and 98th sex-specific percentiles. Three hundred thirty-four 8-to 10-year-old children and their families were randomly assigned to an intervention group, and 329 were assigned to a usual-care (control) group. This study examined data from 232 subjects in the intervention group. Data were collected at 6 intervention sites around the United States. INTERVENTION: Those assigned to the intervention group participated in a multidisciplinary dietary intervention that included a series of group and individual sessions over a 3-year period. Children and their caretakers were taught to follow a nutritionally adequate diet that was low in total fat, saturated fat, and cholesterol and high in polyunsaturated fat. MAIN OUTCOME MEASURES: Three nonconsecutive 24-hour diet recalls were collected at baseline and at 1 year by trained and certified dietitians. A questionnaire designed to assess diet acceptability was administered at months 4, 8, 11, and 15. Demographic measures were collected at the onset of the study. STATISTICAL ANALYSIS PERFORMED: Statistical procedures included factor analysis and regression analysis. RESULTS: Regression analysis suggested that perceived effectiveness of the dietary intervention and mothers' having few concerns about disadvantages of the diet were significantly related to higher overall fat intake in children in one-parent families. Maternal willingness to implement the diet was significantly related to lower saturated fat intake. APPLICATIONS/CONCLUSIONS: In attempts to change eating behavior of children, interest and cooperation of the parents are essential to achieving successful results. These analyses further suggest that maternal acceptability translates into willingness to implement the diet and may facilitate changes that are associated with reduced saturated fat intake in children.

Nutrition Practice Guidelines for Type 1 Diabetes Mellitus positively affect dietitian practices and patient outcomes. The Diabetes Care and Education Dietetic Practice Group.

OBJECTIVES: Assess the acceptance and ease of use of Nutrition Practice Guidelines for Type 1 Diabetes Mellitus by dietitians in a variety of settings; determine if nutrition care activities of dietitians change when practice guidelines are available; measure changes in patient control of blood glucose level, measured as glycated hemoglobin (HbA1c); compare patient satisfaction with care and perceptions about quality of life. DESIGN: Using the approach of outcomes research, volunteer dietitians were recruited and assigned randomly to a usual care group or a practice guidelines group. Patients with type 1 diabetes were enrolled by dietitians and followed up for a 3-month period. Outcome measures included dietitian care activities, changes in patient HbA1c levels, and patient satisfaction and perceptions about quality of life. SUBJECTS/SETTINGS: Dietitians from across the United States who responded to a recruitment notice participated. Their work settings included diabetes referral centers, endocrinology clinics, primary care and community health clinics, hospitals, and a worksite clinic. They recruited patients from their setting for the study. Outcome data were available from dietitians providing care to 24 patients using the new practice guidelines and dietitians providing care to 30 patients using more traditional methods. STATISTICAL ANALYSIS: chi 2 Test, t test, and analysis of covariance. RESULTS: Dietitians in the practice guidelines group spent 63% more time with patients and were more likely to do an assessment and discuss results with patients than dietitians in the usual care group. Practice guidelines dietitians paid greater attention to glycemic control goals. Levels of HbA1c improved at 3 months in 21 (88%) of practice guidelines patients compared with 16 (53%) of usual care patients. Practice guidelines patients achieved greater reductions in HbA1c level than usual care patients (-1.00 vs -0.33). This difference was statistically significant and clinically meaningful. CONCLUSIONS/APPLICATIONS: Dietitians responded positively to practice guidelines for type 1 diabetes. Use of guidelines resulted in changes in dietitian practices and produced greater improvements in patient blood glucose outcomes at 3 months compared with usual care. Practice guidelines did not significantly influence patient satisfaction with care of perceived quality of life.

Effects of diet and sexual maturation on low-density lipoprotein cholesterol during puberty: the Dietary Intervention Study in Children (DISC).

BACKGROUND: The Dietary Intervention Study in Children (DISC) is a multicenter, randomized, controlled clinical trial designed to examine the efficacy and safety of a dietary intervention to reduce serum LDL cholesterol (LDL-C) in children with elevated LDL-C. METHODS AND RESULTS: The effects of dietary intake of fat and cholesterol and of sexual maturation and body mass index (BMI) on LDL-C were examined in a 3-year longitudinal study of 663 boys and girls (age 8 to 10 years at baseline) with elevated LDL-C levels. Multiple linear regression was used to predict LDL-C at 3 years. For boys, LDL-C decreased by 0.018 mmol/L for each 10 mg/4.2 MJ decrease in dietary cholesterol (P<.05). For girls, no single nutrient was significant in the model, but a treatment group effect was evident (P<.05). In both sexes, BMI at 3 years and LDL-C at baseline were significant and positive predictors of LDL-C levels. In boys, the average LDL-C level was 0.603 mmol/L lower at Tanner stage 4+ than at Tanner stage 1 (P<.01). In girls, the average LDL-C level was 0.274 mmol/L lower at Tanner stage 4+ than at Tanner stage 1 (P<.05). CONCLUSIONS: In pubertal children, sexual maturation, BMI, dietary intervention (in girls), and dietary cholesterol (in boys) were significant in determining LDL-C. Sexual maturation was the factor associated with the greatest difference in LDL-C. Clinicians screening for dyslipidemia or following dyslipidemic children should be aware of the powerful effects of pubertal change on measurements of lipoproteins.

Low-fat diet practices of older women: prevalence and implications for dietary assessment.

OBJECTIVE: To evaluate the importance of information on low-fat diet practices and consumption of reduced-fat foods for accurate assessment of energy and fat intakes using a semiquantitative food frequency questionnaire (FFQ). SUBJECTS: Subjects were 7,419 women, aged 50 to 79 years, who filled out an FFQ as part of eligibility screening for a diet modification component and/or a hormone replacement trial in a multicenter study of chronic disease prevention in postmenopausal women (Women's Health Initiative). STATISTICAL ANALYSIS: For 26 FFQ questions, we recoded the low-fat diet choices of participants to a high-fat counterpart and recalculated energy and fat intakes. We then determined the decrease in energy and nutrient estimates attributable to adding low-fat options to the FFQ. RESULTS: Low-fat diet practices were widespread in this population. For example, 69% of respondents rarely or never ate skin on chicken, 76% rarely or never ate fat on meat, 36% usually drank nonfat milk, 52% usually ate low-fat or fat-free mayonnaise, 59% ate low-fat chips/snacks, and 42% ate nonfat cheese. These low-fat choices had substantial effects on energy and nutrient estimates. Absolute decreases (and mean percentage decreases) for energy and nutrient measures attributable to adding low-fat diet options to the FFQ were 196 kcal (11.4%) energy, 9 percentage points in percentage energy from fat (22.3%), 23.2 g fat (29.0%), and 9.6 g saturated fat (32.5%). Black and Hispanic women and women of lower socioeconomic status reported significantly fewer low-fat diet practices than white women and women of higher socioeconomic status. CONCLUSION: Failure to collect information on low-fat diet practices with an FFQ will result in an upward bias in estimates of energy and fat intake, and the amount of error will vary by the personal characteristics of respondents.

Factors associated with adherence to the dietary protein intervention in the Modification of Diet in Renal Disease Study.

OBJECTIVE: To determine the characteristics and behaviors associated with adherence to dietary protein interventions among participants with chronic renal disease in the Modification of Diet in Renal Disease (MDRD) Study. DESIGN: Participants were categorized as consistent adherers or nonadherers on the basis of urinary urea nitrogen excretion and dietary protein intake data from self-reports. Psychosocial and behavioral factors were compared between groups. SUBJECTS: Subgroups of consistently adherent and non-adherent participants in the MDRD Study. SETTING: 15 clinical centers in the United States. INTERVENTION: In the nutrition intervention program, participants were assigned randomly to a usual-, low-, or very-low-protein diet group. Each eating pattern also specified a phosphorus goal. STATISTICAL ANALYSIS: Analysis of variance. RESULT: Psychosocial factors significantly related to adherence included participant knowledge, attitude, support, satisfaction, and self-perception of success. Behavioral strategies including participant self-monitoring of protein intake and the provision of feedback by the dietitian were also significantly related to adherence. APPLICATION: Nutrition interventions for patients with renal disease should focus on psychosocial factors and behavioral approaches. Such approaches can be successfully incorporated into treatment programs and will assist the dietitian in promoting adherence to usual-, low-, and very-low-protein eating patterns.

Protein calculation from food diaries of adult humans underestimates values determined using a biological marker.

We evaluated the ability of a biological marker (nitrogen excretion expressed as protein) to accurately reflect the protein intake of 12 healthy subjects consuming a low protein diet (0.6 g protein/kg standard body wt). In this crossover study, protein intake was confirmed by chemically analyzing a duplicate of the constant diet each subject consumed for 3 d and by calculating protein content of self-selected diets recorded during two additional 3-d periods. Diet analysis matched excretion (difference 0.03 +/- 0.04 g protein/kg standard body wt, means +/- SEM). Self-selected intake manually calculated by subjects using educational materials matched the prescription [0.60 (0.42, 0.86) g protein/kg standard body wt, median (range)], but underestimated excretion by 0.18 +/- 0.02 g protein/kg standard body wt (means +/- SEM). Self-selected intake recalculated by the authors using a computerized database was only +0.05 (-0.08, +0.44) g protein/kg standard body wt higher than subjects' calculations, suggesting that discrepancies between databases and/or subject calculation errors only partially accounted for how greatly self-selected intake underestimated excretion. In a secondary analysis of self-selected intake, the three dietitian subjects consumed more energy and excreted less protein than nondietitians (137 +/- 4.9 vs. 94 +/- 3.5 kJ/standard body wt; 0.72 +/- 0.02 vs. 0.83 +/- 0.02 g protein/kg standard body wt), suggesting that adequate energy intake and/or additional training might improve agreement between intake and excretion. Thus, discrepancies between protein excretion and reported intake may reflect factors other than willful noncompliance.

Serum lipid changes associated with modified protein diets: results from the feasibility phase of the Modification of Diet in Renal Disease Study.

The use of low-protein diets for the management of progressive renal insufficiency may require increases in dietary fats to maintain caloric balance. This raises the concern that such diets might exacerbate the lipid problems already prevalent in chronic renal insufficiency. We present a study in which protein-restricted diets were followed by a group of patients with renal insufficiency without a compensatory increase in fat calories and without adverse effects on serum lipids. Ninety-six patients with renal insufficiency were enrolled in the feasibility phase of the Modification of Diet in Renal Disease Study and were assigned to dietary protein intakes of 1.3, 0.575, or 0.28 g/kg body weight/d. The last diet was supplemented with amino acids or their keto analogs. Of this group, 25 participants were excluded from the present study of lipids because of changes in their intake of medications with known effects on serum lipids, three were excluded because of proteinuria increasing by more than 2 g/d, and seven were excluded because of incomplete measurements. For the remaining 61 participants, median serum total cholesterol at baseline was 215 mg/dL. In 72% of participants it exceeded the age- and sex-adjusted median of the Lipid Research Clinics Prevalence Study. Glomerular filtration rates varied from 8 to 56 mL/min/1.73 m2. The patients' serum lipid levels were stable by 6 months on assigned diets. Serum total and low-density lipoprotein cholesterol levels tended to decrease with reduced protein intake. The baseline to follow-up change in protein intake calculated from urinary urea measurements was significantly correlated with the change in serum total cholesterol (Spearman r = 0.31, P < 0.05) and also with change in low-density lipoprotein cholesterol (r = 0.34, P < 0.01). Surprisingly, correlations between change in serum cholesterol and intake of fats were small in magnitude and did not approach statistical significance. Protein intake did correlate, however, with intake of cholesterol. We conclude that the use of low-protein diets for patients with renal insufficiency did not adversely affect serum lipids.

The Dietary Intervention Study in Children (DISC): dietary assessment methods for 8- to 10-year-olds.

OBJECTIVES: The dietary assessment methods used in the Dietary Intervention Study in Children (DISC) are described and the rationale, validity, and/or general usefulness of each are discussed. DESIGN: DISC is the first multicenter, randomized, clinical trial to study the feasibility and long-term efficacy, safety, and acceptability of a fat-moderately diet in 8- to 10-year-old prepubescent children with moderately elevated plasma low-density lipoprotein cholesterol (LDL-C) levels. Final data collection for the original study (DISC I) occurred December 1, 1993; continued intervention and follow-up (DISC II) will extend beyond 1997. SETTING: Six clinical centers across the country participate in DISC. SUBJECTS: Preadolescent boys and girls with fasting LDL-C levels between the 80th and 98th age-specific and sex-specific percentiles established by the Lipid Research Clinics were eligible for the study. The feasibility phase included 140 children who were then enveloped into the full-scale trial. Baseline dietary data for 652 randomized children in the full-scale trial and 6-month results for the feasibility cohort are reported. INTERVENTIONS: Dietary assessment involved several elements: (a) determining eligibility based on consumption of more than 30% of energy from total fat, (b) monitoring adherence to and adequacy of the intervention diet, (c) evaluating acceptability of the diet in the intervention group, and (d) determining appropriate foods for the intervention diet. Methods are described for each purpose. MAIN OUTCOME MEASURES: LDL-C differences between the two groups and differences in total and saturated fat intakes as calculated from three 24-hour recalls were the primary outcome measures. Six-month dietary differences in the feasibility group are reported. STATISTICAL METHODS: Baseline group means and 6-month differences in dietary intake are reported for the full-scale trial and feasibility study, respectively. RESULTS: Baseline mean intake from three dietary recalls for the intervention (n = 328) and control (n = 324) groups, respectively, were as follows: energy = 1,759 kcal and 1,728 kcal; total energy from fat = 33.3% and 34.0%; total energy from saturated fat = 12.5% and 12.7%; and total dietary cholesterol = 209 mg and 195 mg. After 6 months of intervention, percentage of energy from total fat and saturated fat was reduced by 5.1% (P = .004) and 2.9% (P < .001), respectively, in this feasibility subset (n = 73) of the intervention group. Essentially no change in these parameters occurred in the control group (n = 67), which demonstrates a measurable difference in reporting between groups. APPLICATIONS/CONCLUSIONS: Results illustrate the feasibility of implementing a variety of dietary assessment methods among preadolescent children without relying primarily on parental reports.
