RESUMO

There are limited reports of community-based nutrition education with culinary instruction that measure biomarkers, particularly in low-income and underrepresented minority populations. Teaching kitchens have been proposed as a strategy to address social determinants of health, combining nutrition education, culinary demonstration, and skill building. The purpose of this paper is to report on the development, implementation, and evaluation of Journey to Health, a program designed for community implementation using the RE-AIM planning and evaluation framework. Reach and effectiveness were the primary outcomes. Regarding reach, 507 individuals registered for the program, 310 participants attended at least one nutrition class, 110 participants completed at least two biometric screens, and 96 participants attended at least two health coaching appointments. Participants who engaged in Journey to Health realized significant improvements in body mass index, blood pressure, and triglycerides. For higher risk participants, we additionally saw significant improvements in total and LDL cholesterol. Regarding dietary intake, we observed a significant increase in cups of fruit and a decrease in sugar sweetened beverages consumed per day. Our findings suggest that Journey to Health may improve selected biometrics and health behaviors in low-income and underrepresented minority participants.

RESUMO

Purpose: The objective of this study was to conduct a secondary data analysis of clinical information documented in the electronic medical record to assess the clinical outcomes of patients who received three different treatment approaches on clinical outcomes for treatment of patients with anorexia nervosa (AN). Patients and methods: Historical electronic medical record (EMR) data on patients aged 6 to 80 years diagnosed with AN seen in a healthcare system between 2007 and 2017 were stratified, according to services received, into three groups: Group A (n = 48) received hospital-based services; Group B (n = 290) saw one or two provider types; Group C (n = 26) received outpatient coordinated multidisciplinary care from three provider types. Clinical outcomes [body mass index for adults (BMI), body mass index percentile (BMI%ile) for pediatric patients] defined AN severity and weight restoration. EMR data were analyzed using a generalized mixed-effects model and a Markov Transition model to examine the odds of weight restoration and the change in odds of weight restoration across the number of provider visits, respectively. Results: Patients receiving coordinated multidisciplinary care had significantly higher odds of weight restoration compared with patients receiving hospital-based services only (OR = 3.76, 95% CI [1.04, 13.54], p = 0.042). In addition, patients receiving care from 1 to 2 providers (OR = 1.006, 95% CI [1.003, 1.010], p = 0.001) or receiving coordinated multidisciplinary care (OR = 1.005, 95% CI [1.001, 1.011], p = 0.021) had significantly higher odds of weight restoration per provider visit day compared with patients receiving hospital-based services only. Conclusion: This retrospective chart review supports the coordinated, multidisciplinary care model for the weight restoration in patients with AN in an outpatient setting.

RESUMO

OBJECTIVE: To develop and validate a questionnaire to assess diabetes knowledge, attitudes, beliefs, and intent to change among middle school students. DESIGN: A cross-sectional validation analysis. SETTING: Students in 3 urban middle schools in Utah participated in this study. PARTICIPANTS: The 25-item questionnaire was validated in independent samples of 277 and 304 students in the seventh and eighth grades. VARIABLES MEASURED: The questionnaire includes the following variables: diabetes knowledge, attitudes, beliefs, and intent to change dietary and physical activity behaviors. ANALYSIS: Rigorous statistical approaches, including Cronbach's α (goodness of fit) calculation, test-retest reliability, and exploratory and confirmatory factor analyses, were employed to examine the reliability and construct validity. RESULTS: The Cronbach's α coefficients were 0.7 for both subscales demonstrating acceptable internal consistency. All factor loadings were > 0.4, revealing close relations between factors and items. The confirmatory factor analysis model fit was 0.9 for the comparative fit index and Tucker-Lewis Index, indicating a reasonable model-data fit. CONCLUSIONS AND IMPLICATIONS: This study demonstrated the validity of a diabetes questionnaire for middle school students. Future work is needed to validate its use in a diabetes prevention program, given the growing need for diabetes education among young adolescents.

RESUMO

BACKGROUND: Eosinophilic oesophagitis (EoE) is associated with elevated IgG4 in oesophageal tissue and serum. Previously, we showed brush-collected oesophageal secretions of EoE patients contained food antigen-specific antibodies IgA and IgG4. It is unknown whether other food-specific antibodies are present along the surface of the oesophagus in EoE. AIM: To identify whether immunoglobulins other than IgG4 and food-specific antibodies are elevated along the oesophageal mucosal surface in oesophageal secretions in EoE patients METHODS: Concentrations of total IgA, IgG1, IgG2, IgG3, IgG4, IgM and IgE were measured in oesophageal secretions from patients with active (n = 19) and inactive EoE (n = 9), and non-EoE controls (n = 10). Food-specific antibodies were measured using beads coupled to protein components from dairy, wheat and egg. Total immunoglobulin and cytokine and chemokine concentrations were measured in serum, saliva and oesophageal secretions of four patients with active EoE. RESULTS: Oesophageal secretions have a unique immune profile. Patients with active EoE had elevated IgG2, IgG4 and IgM concentrations in oesophageal secretions compared to those with inactive EoE. Food-specific IgG1, IgG2, IgG4 and IgM were significantly increased in patients with active EoE compared to inactive EoE and non-EoE patients. Furthermore, active patients with a known dairy trigger display higher dairy-specific IgG1, IgG2, IgG4, IgM, IgA and IgE. CONCLUSIONS: There is a distinct localised profile of immunoglobulins and food-specific antibodies found within oesophageal secretions in EoE. These findings expand our knowledge about the currently identified immune responses in EoE and suggest possible roles for multiple immunoglobulins and food-specific antibodies in the pathophysiology of EoE.

RESUMO

Evidence suggests a positive association between sugar intake and colorectal cancer (CRC) outcomes. We sought to investigate inflammation and angiogenesis as underlying mechanisms behind increased sugar intake and worse CRC outcomes. Pre-surgery serum samples were obtained from 191 patients diagnosed with primary invasive stage I-IV CRC. Biomarkers of inflammation (CRP, SAA, IL-6, IL-8, MCP-1, TNFα) and angiogenesis (VEGFA, VEGFD, sICAM-1 and sVCAM-1) were analyzed (Meso-Scale-Discovery). Fructose, glucose, sucrose, and total sugar intake (calories/day, % total calories) were assessed by FFQ. Pearson's correlation and multiple linear regression analyses were performed. Patients were on average 64 years old, 64% were male, the majority was diagnosed with stage II-III (58%) cancers, and 67% were either overweight or obese. Among normal-weight individuals (BMI <25 kg/m2), we observed a significant inverse association between VEGFD and any type of sugar intake in cal/day (sucrose: p = 0.01, glucose and fructose: p < 0.001) and MCP-1 and fructose intake (p = 0.05). The magnitude of reduction in VEGF ranged between -1.24 for sucrose to 4.49 for glucose intake, and -2.64 for fructose intake for MCP-1 levels. Sugar intake was associated with some inflammation or angiogenesis biomarkers, among CRC patients; differences were observed by adiposity that warrant further investigation.Supplemental data for this article is available online at at 10.1080/01635581.2021.1957133.

RESUMO

OBJECTIVES: Previous studies have reported that maternal prepregnancy body mass index (BMI), gestational weight gain (GWG), and child birth weight are positively associated with metabolic dysfunction (a broader term than metabolic syndrome) in children and adolescents. Physical activity habits may play a role in reducing these risk factors. The objectives of this study were to investigate the association of prepregnancy BMI, GWG, child birth weight, physical activity, and sedentary time with metabolic dysfunction in a cohort of children and adolescents with obesity. METHODS: Participants (N = 117; 53% Hispanic) were children and adolescents, aged 8 to 17 years, with obesity. Fasting serum glucose, insulin, and a complete lipid profile were obtained. Body weight, height, waist circumference, and blood pressure were measured. A self-reported survey assessed prepregnancy BMI, GWG, child birth weight, physical activity, and sedentary time. The χ2 test and the Mantel-Haenzel test statistic were used to examine the differences in proportions for the outcome of metabolic dysfunction. RESULTS: In this sample, 76.9% of children and adolescents had metabolic dysfunction. Prepregnancy BMI and GWG were not associated with metabolic dysfunction. Child birth weight and sedentary behavior were positively correlated (P = 0.033 and P = 0.015, respectively) with a diagnosis of metabolic dysfunction. Physical activity levels were not associated with metabolic dysfunction. Hispanic and non-Hispanic youth were similar for all risk factors. CONCLUSIONS: Contrary to previous studies, prepregnancy BMI and GWG were not correlated with metabolic dysfunction. These findings support the need for lifestyle interventions, particularly in reducing sedentary behaviors, in obese children and adolescents.

RESUMO

No study to date has examined the effect of a multicomponent school-based physical activity program on health behavior knowledge in a large sample of low-income children from the US. The purpose of this study was to explore the change in physical activity and nutrition knowledge during a Comprehensive School Physical Activity Program (CSPAP) in children. Participants were a convenience sample of 789 children recruited from the 4th to 6th grades from five low-income Title I schools located within the Mountain West Region of the US. Students completed two questionnaires consisting of a physical activity and a nutrition knowledge assessment. Questionnaires were administered at baseline before the commencement of CSPAP and at a 36-week follow-up. Data were analyzed using a 3 × 2 × 2 doubly MANOVA test. Physical activity knowledge scores significantly improved from pretest to posttest during the intervention (p = 0.045, Cohen's d = 0.18). Grade level modified the time effects, with older children in grades 5 and 6 displaying greater improvements in physical activity knowledge than younger children in grade 4 (p = 0.044, Cohen's d = 0.33). There were no significant improvements in nutrition knowledge scores during the CSPAP (p = 0.150). These findings demonstrate that improvements in physical activity knowledge can occur during a multicomponent school-based intervention. Improvements in physical activity knowledge may translate to improvements in habitual physical activity behaviors and positively influence children's health outcomes, especially in older children.

RESUMO

Coordinated, multidisciplinary treatment for women with eating disorders is consistently recommended as maximally effective, but few studies have considered the patient experience. This qualitative study examined the experiences of women receiving such care in an outpatient setting. Using an interpretive description methodology, we conducted 12 in-depth interviews with participants who were diagnosed with an eating disorder and were receiving team-based treatment. Patients uniformly advocated for the coordinated, multidisciplinary treatment approach. Analysis of participants' experiences yielded four categories: relying on the lifeline of communication, supporting autonomy, drawing on individual strengths, and valuing synergy. These findings build on previous research emphasizing the importance of autonomy support and connectedness in the recovery process from an eating disorder. Findings highlight the importance of nurses to support a multidisciplinary care approach to working with this patient population; these women's voices also support a treatment approach that, despite being widely recommended, is vastly understudied and underutilized.

RESUMO

BACKGROUND: Elementary teachers have the potential to influence children's eating habits. This study examined teacher views and practices regarding nutrition education. METHODS: An online survey was administered to K-6 teachers (N = 628) in 55 public elementary schools in a large city in the western United States. Three indices were created based on responses. Indices included: (1) attitudes and beliefs about nutrition education; (2) self-efficacy regarding nutrition education; and (3) personal health behaviors. Relationships between indices, classroom practices, and teacher characteristics were tested. Teacher comments were categorized into themes. RESULTS: Most teachers agreed they can make a difference in the eating behaviors of their students (68%). Correlations between hours of nutrition taught and teachers' attitudes and beliefs (r = .37, p < .01), nutrition self-efficacy (r = .38, p < .01), and personal health practices (r = .15, p < .01) were weak, yet statistically significant. Number of years teaching was inversely related to frequency of food rewards (r = -119, p < .01). Few teachers (21%) agreed they have support to teach nutrition in the classroom. CONCLUSION: Teachers understand the importance of nutrition education but provision is limited by competing demands. Teachers suggest tailored nutrition materials, qualified nutrition personnel, and school stakeholder support to promote nutrition education.

RESUMO

OBJECTIVES: Increased adiposity increases leptin and decreases adiponectin concentrations, resulting in an increased leptin:adiponectin ratio (LAR). In adults, components of the metabolic syndrome and other cardiometabolic risk factors, what we classify here as "metabolic dysfunction," are associated with both a high LAR and a history of being breast-fed. The relation among breast-feeding, LAR, and degree of metabolic dysfunction in obese youth is unknown. The purpose of our pilot study was to explore this relation and estimate the effect size of the relations to determine the sample size needed to power future prospective studies. METHODS: We obtained fasting levels of leptin, adiponectin, lipids, insulin, and glucose from obese youth (aged 8-17 years). Weight, height, waist circumference, blood pressure, and breast-feeding history also were assessed. RESULTS: Of 96 participants, 78 were breast-fed as infants, 54% of whom were breast-fed for >6 months. Wide variation was observed in LARs among children who were and were not breast-fed (>100% coefficient of variation). Overall, prevalence of metabolic dysfunction in the cohort was 94% and was not proven to be associated with higher LAR. CONCLUSIONS: In this cohort of obese youth, we found a high prevalence of breast-feeding, metabolic dysfunction, and wide variation in the LARs. Based on the effect size estimated, future studies would need to enroll >1500 patients or identify, stratify, and selectively enroll obese patients without metabolic dysfunction to accurately determine whether breast-feeding in infancy influences LARs or metabolic dysfunction among obese youth.

RESUMO

BACKGROUND: Premature birth is associated with increased adipose deposition after birth. Standard anthropometry (body weight, length, and head circumference) may not adequately assess fat deposition. Validated methods to assess adiposity are needed to optimize growth quality in preterm infants. The purpose of this study was to identify covariates of infant body fat. METHODS: Air displacement plethysmography (ADP), standard anthropometry, and body circumferences were measured at hospital discharge in preterm (n = 28; 31-35 wk postmenstrual age (PMA)) and term (n = 28; 38-41 wks PMA) infants. RESULTS: Body weight, length, and head circumference were lower for preterm infants (P < 0.05) at hospital discharge compared with that of term infants. Despite smaller body size and younger PMA, preterm infant percent body fat (%BF) by ADP was 12.33 ± 4.15% vs. 9.64 ± 4.01% in term infants (P = 0.01). Mid-arm circumference (MAC) is a covariate of %BF in both preterm and term infants (adjusted R(2) = 0.49; P < 0.001). In preterm infants alone, MAC accounted for 60.4% of the variability of percent body fat (%BF) by ADP (P < 0.01). CONCLUSIONS: Preterm infants have increased body fat deposition as they approach term-corrected age, and MAC is a reliable, low-cost measure for monitoring infant body fat deposition in preterm and term infants.

RESUMO

Nutrition care and metabolic control contribute to clinical patient outcomes. Biomedical informatics applications represent a way to potentially improve quality and efficiency of nutrition management. We performed a systematic literature review to identify clinical decision support and computerized provider order entry systems used to manage nutrition care. Online research databases were searched using a specific set of keywords. Additionally, bibliographies were referenced for supplemental citations. Four independent reviewers selected sixteen studies out of 364 for review. These papers described adult and neonatal nutrition support applications, blood glucose management applications, and other nutrition applications. Overall, results indicated that computerized interventions could contribute to improved patient outcomes and provider performance. Specifically, computer systems in the clinical setting improved nutrient delivery, rates of malnutrition, weight loss, blood glucose values, clinician efficiency, and error rates. In conclusion, further investigation of informatics applications on nutritional and performance outcomes utilizing rigorous study designs is recommended.

RESUMO

Children with type I spinal muscular atrophy commonly demonstrate reduced bone mineral density. Our objectives were to evaluate and assess adequacy of vitamin D intake, serum levels, and association with bone mineral density. Assessments were completed using 3-day food records and dual energy x-ray absorptiometry scans. The spinal muscular atrophy type I cohort included 22 males and 18 females (N = 40), with a mean age of 18.6 months. Data collection occurred from 2001 to 2011. Seventy-five percent of patients had inadequate intake of vitamin D at the initial visit. Using mixed-effects analyses, vitamin D and calcium intakes correlated positively with bone mineral density (r = 0.31 and r = 0.53, respectively). Increased vitamin D and calcium consumption were associated with an increase in bone mineral density (P = .04 and P = .01, respectively). Vitamin D intake correlated positively with serum levels (r = 0.65). Further study is needed to determine optimal intakes of vitamin D and calcium in the spinal muscular atrophy type I population.

RESUMO

The United States, indeed the world, struggles with a serious obesity epidemic. The costs of this epidemic in terms of healthcare dollar expenditures and human morbidity/mortality are staggering. Surprisingly, clinicians are ill-equipped in general to advise patients on effective, longitudinal weight loss strategies. We argue that one factor hindering clinicians and patients in effective shared decision-making about weight loss is the absence of a metric that can be reasoned about and monitored over time, as clinicians do routinely with, say, serum lipid levels or HgA1C. We propose that a dietary quality measure championed by the USDA and NCI, the HEI-2005/2010, is an ideal metric for this purpose. We describe a new tool, the quality Dietary Information Extraction Tool (qDIET), which is a step toward an automated, self-sustaining process that can link retail grocery purchase data to the appropriate USDA databases to permit the calculation of the HEI-2005/2010.

RESUMO

Grocery sales are a data source of potential value to dietary assessment programs in public health informatics. However, the lack of a computable method for mapping between nutrient and food item information represents a major obstacle. We studied the feasibility of linking point-of-sale data to USDA-SR nutrient database information in a sustainable way. We analyzed 2,009,533 de-identified sales items purchased by 32,785 customers over a two-week period. We developed a method using the item category hierarchy in the supermarket's database to link purchased items to records from the USDA-SR. We describe our methodology and its rationale and limitations. Approximately 70% of all items were mapped and linked to the SR; approximately 90% of all items could be mapped with an equivalent expenditure of additional effort. 100% of all items were mapped to USDA standard food groups. We conclude that mapping grocery sales data to nutritional information is feasible.

RESUMO

BACKGROUND: The National Children's Study proposes to investigate biological, chemical, physical, and psychosocial environmental exposures and their role on health outcomes in pregnant women and children. One specific area of concern is contaminant exposure through the ingestion of solid foods. National food contaminant databases may miss dietary exposures unique to specific communities and sources of food. OBJECTIVE: The purpose of this study was to evaluate the feasibility of community food item collection for the assessment of pesticide exposure in pregnant women and young children. METHODS: A prospective observational design was used to test the food collection protocol in mothers (n=45) of children aged 15-24 months in Salt Lake City, Utah. Foods for collection were based on: 1) frequency of different foods consumed by the target population as determined by the National Health and Nutrition Examination Survey data; 2) child food frequency questionnaire; and 3) likelihood of pesticide contamination in the foods. Assessment measures included: demographics, environmental health survey, quality assurance checklist, and participant evaluation form. RESULTS: An average of three food items were obtained from 44 households, yielding a collection rate of 97.8%. Overall, 100% of the food samples were rated as acceptable. Moreover, a vast majority of mothers reported that the study was not burdensome (95.5%) and that preparing the food sample was easy (93.2%). CONCLUSIONS: This study suggests that the community food item collection methodology shows promise as a low-burden approach for capturing dietary exposures on a household level, and appears to be a feasible tool for large population studies to assess dietary exposures unique to specific communities.

RESUMO

Metabolic syndrome is a group of disorders involving obesity, insulin resistance, dyslipidemia and hypertension. Obesity is the most crucial risk factor of metabolic syndrome, because it is known to precede other risk factors. Obesity is also associated with disturbances in the metabolism of the trace mineral, zinc. The overall purpose of this study was to investigate the effects of short-term weight loss on plasma zinc and metabolic syndrome risk factors. An 8-week weight loss intervention study was conducted with 90 low-income overweight/obese mothers, whose youngest child was 1-3 years old. Plasma levels of zinc, glucose, insulin, leptin, triglycerides, total, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol were measured and compared at weeks 0 and 8 of the weight loss program. At pre-study, plasma zinc was low in 39% and, within normal values in 46%, of obese/overweight mothers. By the end of intervention, plasma zinc rose by 22% and only 5% of the mothers continued to exhibit low plasma zinc. At post-study, the metabolic syndrome risk factors of waist circumference, HDL cholesterol, and diastolic blood pressure (p<0.05) showed significant improvements. Plasma zinc increased by a greater margin (67%) in women with low zinc, as compared to those with normal zinc (18%); weight reduction was similar in both the groups. Finally, changes in % body fat were related negatively with changes in plasma zinc (r=- 0.28, p<0.05). The circulating levels of zinc, as well as the metabolic syndrome components, showed significant improvements in overweight/obese low-income women after weight loss.

RESUMO

Limited surveys are available to assess the nutrition knowledge of children. The goals of this study were to test the validity and reliability of a computer nutrition knowledge survey for elementary school students and to evaluate the impact of the "Fit Kids 'r' Healthy Kids" nutrition intervention via the knowledge survey. During survey development, a sample (n=12) of health educators, elementary school teachers, and registered dietitians assessed the survey. The target population consisted of first- through fourth-grade students from Salt Lake City, UT, metropolitan area schools. Participants were divided into reliability (n=68), intervention (n=74), and control groups (n=59). The reliability group took the survey twice (2 weeks apart); the intervention and control groups also took the survey twice, but at pre- and post-intervention (4 weeks later). Only students from the intervention group participated in four weekly nutrition classes. Reliability was assessed by Pearson's correlation coefficients for knowledge scores. Results demonstrated appropriate content validity, as indicated by expert peer ratings. Test-retest reliability correlations were found to be significant for the overall survey (r=0.54; P<0.001) and for all subscales: food groups, healthful foods, and food functions (r=0.51, 0.65, and 0.49, respectively; P<0.001). Nutrition knowledge was assessed upon program completion with paired samples t tests. Students from the intervention group demonstrated improvement in nutrition knowledge (12.2+/-1.9 to 13.5+/-1.6; P<0.001), while scores for the control group remained unchanged. The difference in total scores from pre- to post-intervention between the two groups was significant (P<0.001). These results suggest that the computerized nutrition survey demonstrated content validity and test-retest reliability for first- through fourth-grade elementary school children. Also, the study results imply that the Fit Kids 'r' Healthy Kids intervention promoted gains in nutrition knowledge. Overall, the computer survey shows promise as an appealing medium for assessing nutrition knowledge in children.

RESUMO

INTRODUCTION: Few studies have evaluated the accuracy of parental perceptions of their child's weight status. METHODS: A cross-sectional sample of children aged 5 to 12 years and their parents (n = 576 parent-child pairs) was enrolled from four schools. Child height and weight were measured. The parents classified their child on Likert scales ranging from "extremely overweight" to "extremely underweight." Parental perceptions were compared with their child's weight status according to body mass index (BMI) age-gender percentiles. Fisher-Halton-Freeman tests, chi(2), and logistic regression were used to compare demographic factors between parents who inaccurately estimated and those who accurately estimated child weight status. RESULTS: Misclassification occurred 25% of the time (95% confidence interval: 21.4-28.5). All parents of children with a BMI greater than or equal to the 95th percentile classified their child in a category other than "extremely overweight," and 75% of children with a BMI from the 85th to less than the 95th percentile were misclassified as "about right" or "underweight." Boys were more likely to be misclassified than were girls (29% vs 21%, P = .03). CONCLUSIONS: The majority of parents of obese and overweight children underestimate their child's weight status. Parents of boys are more likely to perceive their child's weight incorrectly.

RESUMO

The purpose of this study was to evaluate a nutrition and physical activity program for reducing body weight and improving nutrition attitudes in mothers of young children. A convenience sample of 114 intervention mothers and 33 comparison mothers was recruited from public health clinics and community centers. Eligibility criteria included Hispanic, African American, or white ethnicity; body mass index of at least 25 kg/m(2); low income (< 200% of the federal poverty index); and youngest child aged 1 to 4 years. For intervention participants, height, weight, percentage of body fat, waist circumference, demographics, nutrition attitudes, and dietary intake were measured at weeks 0 and 8; height, weight, percentage of body fat, and waist circumference were reassessed at 6 months. Overweight mothers in the comparison group provided anthropometric and demographic data at weeks 0 and 8. Changes in anthropometrics, attitudes, and dietary intake were evaluated in intervention mothers. Anthropometric data of intervention vs comparison group mothers were examined. Differences in anthropometrics and attitude scores between weight loss responders (> or = 2.27 kg) and nonresponders (< 2.27 kg) were assessed at week 8. Intervention participants lost weight (x = -2.7 kg; P < .001), whereas comparison mothers gained a slight amount of weight (x = 0.1 kg) by week 8. Weight loss responders had healthier eating attitudes (5.6 vs 5.2; P < .01) and fewer perceived barriers (2.4 vs 2.9; P < .05) than nonresponders postintervention. In conclusion, this dietary and physical activity curriculum is a valuable resource for weight management programs serving low-income women.
