RESUMEN
OBJECTIVE: Outcomes from produce prescription (PPR) programs, an exemplar of a Food is Medicine intervention, have not been synthesized. The objective of this study was to conduct a systematic review to examine the impact of PPR programs on food security, fruit and vegetable (FV) intake, and/or cardiovascular risk factors (HbA1c, blood pressure, and blood lipids). DESIGN: Searches were conducted across three databases (PubMed, CINAHL, and Web of Science). Eligible studies were published between August 2012 and April 2023, conducted in the US in child/family, or adult populations, written in English and had a PPR program as an exposure. OUTCOMES VARIABLES MEASURED: Food security, FV intake, and/or cardiovascular risk factors. RESULTS: Twenty studies ranging from a duration of between 6 weeks to 24 months were included. Of the 5 studies (3 in child/family and 4 in adult populations) that analyzed changes in food security status, all reported significant (P < 0.05) improvements after the PPR program. Approximately half of the included studies found significant (P < 0.05) increases in fruit, vegetable, and/or FV intake. Only studies in adult populations included cardiovascular risk factor outcomes. In these studies, mixed findings were reported; however, there were significant (P < 0.05) improvements in HbA1c when PPR programs enrolled individuals with type 2 diabetes. CONCLUSIONS AND IMPLICATIONS: PPR programs provide an opportunity to improve food security in child/family, and adult populations. Evidence to support whether PPR programs increase FV intake and improve cardiovascular disease risk factors outside of HbA1c in adult populations with high HbA1c upon enrollment is less known.
RESUMEN
BACKGROUND: Muscle assessment is an important component of nutrition assessment. The Global Leadership Initiative on Malnutrition (GLIM) consortium recently underscored the need for more objective muscle assessment methods in clinical settings. Various assessment techniques are available; however, many have limitations in clinical populations. Computed tomography (CT) scans, obtained for diagnostic reasons, could serve multiple purposes, including muscle measurement for nutrition assessment. Although CT scans of the chest are commonly performed clinically, there is little research surrounding the utility of pectoralis muscle measurements in nutrition assessment. The primary aim was to determine whether CT-derived measures of pectoralis major cross-sectional area (PMA) and quality (defined as mean pectoralis major Hounsfield units [PMHU]) could be used to identify malnutrition in patients who are mechanically ventilated in an intensive care unit (ICU). A secondary aim was to evaluate the relationship between these measures and clinical outcomes in this population. METHODS: A retrospective analysis was conducted on 33 pairs of age- and sex-matched adult patients who are being mechanically ventilated in the ICU. Patients were grouped by nutrition status. Analyses were performed to determine differences in PMA and mean PMHU between groups. Associations between muscle and clinical outcomes were also investigated. RESULTS: Compared with nonmalnourished controls, malnourished patients had a significantly lower PMA (P = 0.001) and pectoralis major (PM) index (PMA/height in m2; P = 0.001). No associations were drawn between PM measures and clinical outcomes. CONCLUSION: These findings regarding CT PM measures lay the groundwork for actualizing the GLIM call to action to validate quantitative, objective muscle assessment methods in clinical settings.

BACKGROUND: Although infants with congenital heart disease (CHD) are able to breastfeed successfully, the factors that affect feeding human milk across the first year are not well established. PURPOSE: The objective of this study was to examine breastfeeding characteristics and their relationships to the exclusivity and duration of feeding human milk among infants with CHD. METHODS: Breastfeeding characteristics data from a cohort of 75 infants with CHD enrolled in a study that examined relationships among milk type and infant growth in the first year of life were analyzed. RESULTS: Infants whose mothers reported not having enough milk were exclusively fed human milk for a shorter duration than those who did not have this challenge ( P = .04); however, the duration of feeding any human milk did not differ ( P = .18). Average daily volume expressed at 1 month was positively related to the duration of exclusive human milk (ß = .07, P = .04) and any human milk (ß = .07, P = .04) feeding. CONCLUSIONS: Future efforts to support feeding human milk in infants with CHD should emphasize practices that support maximal human milk production.

BACKGROUND: Malnutrition in the hospital negatively impacts outcomes, including readmissions, mortality, and cost. Starvation-related malnutrition (SRM) is a state of chronic undernutrition with little to no inflammation. Research on SRM within the hospital setting is lacking. Our objective was to determine the prevalence and characteristics of malnutrition within the hospital, focusing on characteristics associated with readmissions in those with SRM. METHODS: We conducted a retrospective cohort study analyzing characteristics of adult in patients with acute disease-related malnutrition (ADM) and chronic disease-related malnutrition (CDM) compared with patients with SRM. Prevalence of all malnutrition types was calculated as the total number of malnourished patients divided by the total number of hospital discharges. Analysis of variance with Tukey post hoc analysis was performed to determine differences between characteristics of patients with SRM and other forms of malnutrition. RESULTS: Total prevalence of malnutrition was 2.8%. Of malnourished patients, 17.6%, 79.9%, and 2.5% had ADM, CDM, and SRM, respectively. Patients with SRM had lower body mass index (BMI) (P < .001) and higher rates of readmission (P = 0.046), infectious disease (P < .001), psychiatric disease (P < .001), and substance abuse (P < .001) than patients with ADM or CDM. Readmitted patients with SRM had lower BMI and higher rates of infection and drug abuse than those without readmission. CONCLUSION: The high incidence of comorbid substance abuse and mental illness in patients with SRM provide important targets for treatment that might reduce readmission and improve outcomes.

OBJECTIVES: Bacterial vaginosis (BV), a clinical condition characterized by decreased vaginal Lactobacillus spp., is difficult to treat. We examined associations between micronutrient intake and a low-Lactobacillus vaginal microbiota as assessed by molecular methods (termed "molecular-BV"). METHODS: This cross-sectional analysis utilized data collected at the baseline visit of the Hormonal Contraception Longitudinal Study, a cohort of reproductive-aged women followed over 2 years while initiating or ceasing hormonal contraception (HC). The Block Brief 2000 Food Frequency Questionnaire was administered and micronutrient intakes were ranked. Vaginal microbiota composition was assessed using 16S rRNA gene amplicon sequencing and clustered into community state types (CSTs) based on the types and relative abundance of bacteria detected. Associations between the lowest estimated quartile intake of nutrients and having a low-Lactobacillus CST (molecular-BV) were evaluated by logistic regression. Separate models were built for each nutrient controlling for age, body mass index, behavioral factors, HC use and total energy intake. We also conducted a literature review of existing data on associations between micronutrient intakes and BV. RESULTS: Samples from 104 women were included in this analysis. Their mean age was 25.8 years (SD 4.3), 29.8% were African American, 48.1% were using HC, and 25% had molecular-BV. In adjusted multivariable analyses, the lowest quartile of betaine intake was associated with an increased odds of molecular-BV (aOR 9.2, p value < 0.01, [CI 2.4-35.0]). CONCLUSIONS: This is the first study to assess the association between estimated micronutrient intake and molecular-BV. Lower energy-adjusted intake of betaine was associated with an increased risk of molecular-BV. Betaine might have direct effects on the vaginal microenvironment or may be mediated through the gut microbiota. Additional research is needed to determine reproducibility of this finding and whether improved intake of select micronutrients such as betaine decreases the risk of BV and its sequelae.

OBJECTIVE: Gastrointestinal disturbances are common in people with cystic fibrosis (CF); however, motility studies in this population have yielded inconsistent results. This study examined gastric emptying (GE) and small bowel transit (SBT) time in children with CF and pancreatic insufficiency compared with a healthy adult reference group. METHODS: Participants consumed an 8-ounce liquid test meal (approximately 550 calories, 32 g of fat) labeled with 300 µCi 99m technetium (Tc) sulfur colloid. Subjects with CF received a standard dose of pancreatic enzymes before consuming the test meal. GE and SBT were measured using a standard nuclear medicine scan. GE was determined after correcting for 99mTc decay in both anterior and posterior images. SBT was determined by following the movement of the tracer from the stomach to the cecum. The percentage arrival of total small bowel activity at the terminal ileum and cecum/ascending colon at 6 hours was used as an index of SBT. A 1-way analysis of covariance was performed for comparisons between groups after adjustment for age, sex, and body mass index. RESULTS: Subjects with CF (n = 16) had similar GE compared with the healthy reference group (n = 12); however, subjects with CF had significantly prolonged SBT time. At 6 hours, 37.2% ± 25.4% (95% CI 23.7-50.7) of the tracer reached the terminal ileum and colon compared with 68.6% ± 13.1% (95% CI 60.2-76.9) for the reference group (P < 0.001). After controlling for sex, age, and body mass index, this difference remained statistically significant (F = 12.06, adjusted R = 0.44, P < 0.002). CONCLUSIONS: Children with CF and pancreatic insufficiency had unaltered GE but delayed SBT time when taking pancreatic enzymes.

OBJECTIVE: The purpose of this study was to develop a survey of general and diabetes-specific nutrition knowledge for youth with type 1 diabetes and their parents and to assess the survey's psychometric properties. RESEARCH DESIGN AND METHODS: A multidisciplinary pediatric team developed the Nutrition Knowledge Survey (NKS) and administered it to youth with type 1 diabetes (n = 282, 49% females, 13.3 ± 2.9 years) and their parents (82% mothers). The NKS content domains included healthful eating, carbohydrate counting, blood glucose response to foods, and nutrition label reading. Higher NKS scores reflect greater nutrition knowledge (score range is 0-100%). In youths, glycemic control was assessed by A1C, and dietary quality was determined by the Healthy Eating Index-2005 (HEI-2005) derived from 3-day diet records. Validity was based on associations of NKS scores with A1C and dietary quality. Reliability was assessed using the Kuder-Richardson Formula 20 (KR-20) and correlations of domain scores to total score. RESULTS: Mean NKS scores (23 items) were 56.9 ± 16.4% for youth and 73.4 ± 12.5% for parents. The KR-20 was 0.70 for youth and 0.59 for parents, representing acceptable internal consistency of the measure. In multivariate analysis, controlling for youth age, family income, parent education, diabetes duration, and insulin regimen, parent NKS scores were associated with corresponding youth A1C (ß = -0.13, P = 0.03). Both parent (ß = 0.20, P = 0.002) and youth (ß = 0.25, P < 0.001) NKS scores were positively associated with youth HEI-2005 scores. CONCLUSIONS: The NKS appears to be a useful measure of general and diabetes-specific nutrition knowledge for youth with type 1 diabetes and their parents.

Bacterial vaginosis (BV) is a common condition of unknown etiology and has been linked to adverse reproductive and obstetric health outcomes. Prior dietary research on BV has focused on specific macro- and micronutrients, but not dietary indices. We assessed the relationship between BV and selected dietary indicators among a cohort of 1735 nonpregnant women ages 15-44 y from Birmingham, Alabama. Annual intake was assessed with the Block98 FFQ, and the glycemic index, glycemic load (GL), and Healthy Eating Index were calculated by the Block Dietary Data System. The Naturally Nutrient Rich (NNR) score was also calculated. Vaginal flora was evaluated using Nugent Gram-stain criteria. Crude OR and adjusted OR were determined by multinomial and logistic regression in cross-sectional and prospective analyses, respectively. Participants were predominantly African American (85.5%) aged 25.3 ± 6.8 y (mean ± SD). Per 10-unit increase, GL was positively (adjusted OR = 1.01, 95% CI = 1.00-1.03) and NNR was negatively (adjusted OR = 0.93, 95% CI = 0.88-0.99) associated with BV compared to normal vaginal flora. In prospective analyses, only GL was associated with BV progression (adjusted OR = 1.03, 95% CI = 1.00-1.05) and persistence (adjusted OR = 1.02, 95% CI = 1.01-1.04) after adjustment. Both GL and NNR were associated with greater BV prevalence and GL was associated with an increase in BV persistence and acquisition. These results suggest that diet composition may contribute to vaginal flora imbalances and be important for elucidating the etiology of BV.

Dominant hand maximal handgrip strength evaluated with a handgrip dynamometer and peak power evaluated with a force plate, adjusted for body size and composition, were compared in African-American children aged 5 to 13 years, with and without type SS sickle cell disease (SCD-SS). Children with SCD-SS (n = 35; age, 9.0 ± 2.0 y) compared with healthy control children (n = 103; age, 8.6 ± 1.8 y) did not differ by age, sex, or pubertal status, yet had significantly lower Z scores for height, weight, body mass index, upper arm muscle area, upper arm fat area, fat mass-for-height and lean mass-for-height. Children with SCD-SS had significantly lower handgrip strength (12.7 ± 3.3 vs. 15.2 ± 5.1 kg, P < 0.008), peak power (882 ± 298 vs. 1167 ± 384 W, P < 0.001), and growth and body composition adjusted Z scores for handgrip strength (0.6 ± 1.3 standard deviations, P < 0.004) and peak power (male children = 1.0 ± 0.8 standard deviations, P < 0.0002; female children = 1.0 ± 1.7 standard deviations, P < 0.006). Maximal muscle strength and peak power are attenuated in children with SCD-SS compared with healthy control children beyond expectation for growth and body composition deficits suggesting that additional factors contribute to attenuation in anaerobic performance.

PURPOSE: To examine the association between food sold in school vending machines and the dietary behaviors of students. METHODS: The 2005-2006 U.S. Health Behavior in School-aged Children survey was administered to 6th to 10th graders and school administrators. Dietary intake in students was estimated with a brief food frequency measure. School administrators completed questions regarding food sold in vending machines. For each food intake behavior, a multilevel regression analysis modeled students (level 1) nested within schools (level 2), with the corresponding food sold in vending machines as the main predictor. Control variables included gender, grade, family affluence, and school poverty index. Analyses were conducted separately for 6th to 8th and 9th-10th grades. RESULTS: In all, 83% of the schools (152 schools; 5,930 students) had vending machines that primarily sold food of minimal nutritional values (soft drinks, chips, and sweets). In younger grades, availability of fruit and/or vegetables and chocolate and/or sweets was positively related to the corresponding food intake, with vending machine content and school poverty index providing an explanation for 70.6% of between-school variation in fruit and/or vegetable consumption and 71.7% in sweets consumption. Among the older grades, there was no significant effect of food available in vending machines on reported consumption of those food. CONCLUSION: Vending machines are widely available in public schools in the United States. In younger grades, school vending machines were either positively or negatively related to the diets of the students, depending on what was sold in them. Schools are in a powerful position to influence the diets of children; therefore, attention to the food sold at school is necessary to try to improve their diets.

BACKGROUND: A Mediterranean diet has been associated with a reduced risk of cardiovascular disease and mortality. A possible mechanism is through a decrease in lipid peroxidation (LPO); however, evidence linking the Mediterranean diet with lower LPO in premenopausal women is sparse. OBJECTIVE: We investigated whether adherence to a Mediterranean diet was associated with lower LPO concentrations in premenopausal women. DESIGN: Two hundred fifty-nine healthy women aged 18-44 y were followed for ≤ 2 menstrual cycles. Plasma concentrations of F(2)-isoprostane (8-iso-PGF2α), 9-hydroxyoctadecadieneoic acid (9-HODE), and thiobarbituric acid reactive substances (TBARS) were measured ≤ 8 times per cycle at visits scheduled by using fertility monitors. Diet was assessed ≤ 4 times per cycle by using 24-h dietary recalls. The alternate Mediterranean Diet Score (aMED) (range: 0-9) was calculated on the basis of intake of vegetables, legumes, fruit, nuts, whole grains, red and processed meat, fish, and alcohol and the ratio of monounsaturated to saturated fat. RESULTS: A 1-unit increase in aMED was associated with a 4.50% decrease in 8-iso-PGF2α concentrations (95% CI: -6.32%, -2.65%) and a 14.01% decrease in 9-HODE concentrations (95% CI: -17.88%, -9.96%) after adjustment for energy intake, age, race, body mass index, plasma ascorbic acid, and serum cholesterol. No significant association was observed between aMED and TBARS. A 1-unit increase in aMED was associated with a 1.39% increase (95% CI: 0.07%, 2.72%) in plasma ascorbic acid concentrations. CONCLUSIONS: Adherence to a Mediterranean diet is associated with lower LPO and higher ascorbic acid concentrations. These results confirm that decreased LPO is a plausible mechanism linking a Mediterranean diet to reduced cardiovascular disease risk.

Dietary management of type 1 diabetes mellitus has become much less restrictive and more flexible in recent years due to contemporary insulin regimens, which may afford families of children with type 1 diabetes mellitus greater ease in sharing family meals. Although these treatment advancements might facilitate family meals, overall demands of diabetes management can influence family's perceived or actual ability to do so. Youths with type 1 diabetes mellitus (ages 8 to 20 years) and parents participated in separate focus groups. Thirty-five youths with type 1 diabetes mellitus (mean age=15.1+/-3.6 years) and their parents participated in 21 focus groups (12 youth groups, nine parent groups). Although there was substantial variability in how often family meals occurred, both parents and youths consistently perceived family meals as valuable and enjoyable. The major barrier to family meals discussed by both youths and parents was busy schedules. Strategies for having family meals that were discussed by parents included shopping to ensure availability of the foods needed to prepare meals, planning, and cooking meals in advance, and using simplified cooking methods. These findings suggest that a family-focused approach to nutrition interventions in this population, as opposed to one targeting the child with diabetes only, can improve the chance for successful dietary change.

In premenopausal women, elevated C-reactive protein (CRP) concentrations have been associated with an increased risk of negative reproductive outcomes. Whole grain consumption has been associated with lower CRP concentrations in older women; however, less is known about this relationship in younger women. We investigated whether whole grain intake was associated with serum high sensitivity CRP (hs-CRP) concentrations in young women. BioCycle was a prospective cohort study conducted at the University of Buffalo from 2005 to 2007, which followed 259 healthy women aged 18-44 y for

OBJECTIVE: The purpose of the present analysis was to examine secular trends in school performance indicators in relationship to the implementation of a programme targeting the school food and physical activity environment. DESIGN: Data on available school performance indicators were obtained; retrospective analyses were conducted to assess trends in indicators in association with programme implementation; each outcome was regressed v. year, beginning with the year prior to programme implementation. SETTING: The Healthy Kids, Smart Kids programme, a grass-roots effort to enhance the school food and physical activity environment in the Browns Mill Elementary School in Georgia. SUBJECTS: Data included publicly available school records from the years 1995 to 2006. RESULTS: The number of nurse, counselling and disciplinary referrals per 100 students demonstrated a downward trend, while standardized test scores demonstrated an upward trend beginning in the year of programme implementation. School year was a significant predictor of all indicators. CONCLUSIONS: Promoting nutrition and physical activity within the school environment may be a promising approach for enhancing both student health and educational outcomes.

OBJECTIVE: To assess perceptions of healthful eating and the influence of diabetes management on dietary behaviors among youth with type 1 diabetes and parents. RESEARCH DESIGN AND METHODS: Youth with type 1 diabetes (n = 35), ages 8-21 years, and parents participated in focus groups. Focus group recordings were transcribed and coded into themes. Clinical data were abstracted from the electronic medical record. RESULTS: Central topics were perceptions of healthful eating and the impact of diabetes management on diet. An emphasis on limiting postprandial glycemic excursions occasionally contradicted the traditional perception of healthful eating, which emphasized consumption of nutrient-dense whole foods in favor of prepackaged choices. Whereas fixed regimens required more rigid diets, basal-bolus regimens provided more opportunities for unhealthful eating. Most youth perceived "refined" grains as more healthful grains. CONCLUSIONS: For youth with type 1 diabetes and parents, an emphasis on carbohydrate quantity over quality may distort beliefs and behaviors regarding healthful eating.

PURPOSE: This pilot study investigated the acceptability of whole grain and legume foods in youths with type 1 diabetes and determined demographic and behavioral factors associated with their acceptability. METHODS: Youths with type 1 diabetes (7.0 to 16.9 years) were recruited during a diabetes camp and completed self-report measures of food acceptability, eating behaviors, and demographics. An overall acceptability score for whole grains and for legumes was calculated as the sum of foods in each category rated as either "tried and liked" or "not tried and willing to try." Correlations of whole grain and legume acceptability with demographic characteristics were examined. RESULTS: One hundred twenty-eight youths participated (70% females, mean age 11.6 +/- 2.3 years). Whole grain foods with the highest acceptability were corn bread (85% tried/liked and 11% willing to try) and whole wheat bread (72% tried/liked and 3% willing to try). Total whole grain acceptability was negatively associated with days per week of fast food consumption (r = -0.21; P < .02) and living in an urban environment (r = -0.24; P < .01). Chili with beans (66% tried/liked and 8% willing to try) and baked beans (57% tried/liked and 19% willing to try) were the legume-containing foods with the highest acceptability. There were no significant associations between demographic factors and total legume acceptability. CONCLUSIONS: These findings demonstrate the variability in acceptability among whole grains and legumes in youths with type 1 diabetes and the importance of addressing acceptability when counseling youths or designing nutrition interventions to improve consumption of these foods.

PURPOSE: The purpose of this study is to review the literature on usual dietary intake in children with type 1 diabetes (T1D) and to discuss approaches to promote dietary change with potential efficacy. METHODS: Search strategies included a MEDLINE search for English-language articles that estimated usual dietary intake in children with T1D and a screening of the reference lists from original studies. The keywords used were diet, dietary intake, nutrition, type 1 diabetes, children, adolescents, and youth. Studies were included if they were observational, contained a sample of children with T1D, and estimated usual dietary intake. RESULTS: Nine studies fulfilled the criteria (6 US, 3 European). Of the 4 studies with a control group, 3 reported that both total fat and saturated fat intake were higher in the children with T1D. Six studies examined the percent of total calories from saturated fat; mean intake ranged from 11 to 15%, exceeding ADA recommendations (< 7%). Fruit, vegetable, and fiber intakes were low among children with T1D. No prior studies have addressed dietary change in this population. The behavior-change literature suggests that nutrition education alone is unlikely to be adequate, but that incorporation of behavioral approaches offers potential efficacy in promoting healthful dietary change. CONCLUSIONS: Children with T1D are not meeting dietary guidelines, and in some areas their diets are less healthful than children without diabetes. As these dietary behaviors may affect the risk of long-term complications, the incorporation of behavioral approaches promoting healthy eating into routine clinical practice is warranted.

A low-glycemic index (GI) diet may lower postprandial hyperglycemia and decrease the risk for postabsorptive hypoglycemia in people with type 1 diabetes. However, insufficient evidence exists on the efficacy of a low-GI diet to support practice recommendations. The goal of this study was to examine the blood glucose response to and the macronutrient composition of low-GI meals vs usual meals consumed ad libitum at home in children with type 1 diabetes. A within-subject, crossover design was employed. Twenty-three participants were recruited between June and August 2006. Participants wore a continuous blood glucose monitoring system and completed diet diaries on 2 days. On 1 day, participants consumed their usual meal; on another day, participants consumed low-GI meals ad libidum. Order of the 2 days was counterbalanced. The mean GI was 34+/-6 for the low-GI day and 57+/-6 for the usual meal day (P<0.0001). During the low-GI day, mean daytime blood glucose values (125+/-28 mg/dL [6.9+/-1.5 nmol/L] vs 185+/-58 mg/dL [10.3+/-3.2 nmol/L], P<0.001), blood glucose area above 180 mg/dL (4,486+/-6,138 vs 26,707+/-25,038, P<0.006), and high blood glucose index (5.1+/-5.1 vs 13.6+/-7.6, P<0.001) were lower compared to the usual mean day. During the low-GI day, subjects consumed more fiber (24.5+/-12.3 g vs 14.5+/-6.1 g, P<0.007) and less fat (45.7+/-12.2 g vs 76.8+/-32.4 g, P<0.005); however, there were no differences in energy, carbohydrate, or protein intake. In this pilot study, a low-GI diet was associated with improved diet quality and a reduction in hyperglycemia.

OBJECTIVE: To develop and test a youth-report measure of collaborative parent involvement in type 1 diabetes management. METHODS: Initial item development and testing were conducted with 81 youths; scale refinement and validation were conducted with 122 youths from four geographic regions. Descriptive statistics, Cronbach's alpha, and factor analyses were conducted to select items comprising the scale. Correlations with parenting style and parent diabetes responsibility were examined. Multiple regression analyses examining associations with quality of life, adherence, and glycemic control were conducted to assess concurrent validity. RESULTS: The measure demonstrated strong internal consistency. It was modestly associated with parenting style, but not with parent responsibility for diabetes management. A consistent pattern of associations with quality of life and adherence provide support for the measure's concurrent validity. CONCLUSIONS: This brief youth-report measure of parent collaborative involvement assesses a unique dimension of parent involvement in diabetes management associated with important youth outcomes.
