A pilot and feasibility study to assess children's consumption in quick-service restaurants using plate waste methodology.

BACKGROUND: Children regularly consume foods from quick-service restaurants (QSR), but little is known about the foods that children order, the calories and nutrients consumed, the accuracy of stated calorie information, or the ability to assess food orders and consumption in QSRs. This study evaluated the feasibility of plate waste collection in QSRs and examined children's orders and consumption of meals from the standard and children's menus. Additional aims were to examine if the meals ordered met healthier standards for children's menu items and determine the accuracy of the QSR-stated energy content of foods. METHODS: Fifteen QSRs, two malls, and 116 eligible parents were approached to participate in the study in 2015. Among the families recruited, children's meal orders and consumption were analyzed using plate waste methodology, and a subsample of foods was analyzed using bomb calorimetry in 2015. RESULTS: Two individual QSRs and one mall food court with two QSRs agreed to participate, and n = 50 participants (parents with children between the ages of 5-10 years) were recruited. Children consumed on average 519 calories, 5.7 g saturated fat, 957 mg sodium, 3.7 g fiber, and 22.7 g sugar. Children ordered and consumed significantly fewer calories and less sodium and sugar with meals ordered exclusively from the children's menu compared with the standard menu. Overall there were no significant differences between the measured and stated energy contents of the QSR foods. CONCLUSIONS: Conducting plate waste research in QSRs is feasible and there is concordance with stated calorie information. Consuming foods exclusively from the children's menu may help limit overconsumption in QSRs.

White matter injury and the inflammatory response following neonatal cardiac surgery.

White matter injury (WMI) is a known complication following neonatal heart surgery in term infants. In preterm infants, WMI has been associated with the degree of systemic inflammation. It is not known whether inflammation is an important mechanism of WMI as documented by magnetic resonance imaging (MRI) following neonatal heart surgery with cardiopulmonary bypass. Term neonates with congenital heart disease were enrolled in a prospective study with postoperative MRI. White matter injury was recorded by the number of T1 hyperintense foci with >5 foci consistent with significant WMI. Eleven candidate cytokine markers (INF-gamma, TNF-alpha, IL-1 beta, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, and IL-13) were assayed preoperatively and daily for 5 days following surgery. Multiple clinical factors were recorded and correlated with WMI. Ninety-two subjects were enrolled in the study. The median age at surgery was 5 days (interquartile range 4-7 days). Compared with the presurgery level, there were statistically significant increases (p < 0.005) for 8 out of 11 inflammatory markers. In all, 64 postoperative MRIs were performed. No significant correlation was detected between WMI and clinical variables or inflammatory markers assessed immediately postoperative and on postoperative days 1 and 3, with exception of IL-1 beta on postoperative day 1. WMI correlates poorly with the systemic inflammatory response after congenital heart surgery and a number of herein measured clinical factors. WMI following neonatal heart surgery is a complex, still incompletely understood phenomenon that warrants continued investigation.

Reliability and Validity of Digital Images to Assess Child Dietary Intake in a Quick-Service Restaurant Setting.

BACKGROUND: Development of methods to accurately measure dietary intake in free-living situations-restaurants or otherwise-is critically needed to understand overall dietary patterns. OBJECTIVE: This study aimed to develop and test reliability and validity of digital images (DI) for measuring children's dietary intake in quick-service restaurants (QSRs), validating against weighed plate waste (PW) and bomb calorimetry (BC). DESIGN: In 2016, cross-sectional data were collected at two time points within a randomized controlled trial assessing children's leftovers in QSRs from parents of 4- to 12-year-old children. PARTICIPANTS/SETTING: Parents (n = 640; mean age = 35.9 y; 70.8% female) consented and agreed to provide their child's PW for digital imaging, across 11 QSRs in Massachusetts in areas with low socioeconomic status and ethnically diverse populations. OUTCOME MEASURES: Outcome measures were interrater reliability for DIs, correspondence between methods for energy consumed and left over, and correspondence between methods across varying quantities of PW. ANALYSES PERFORMED: Intraclass correlations, percent agreement, Spearman correlations, Wilcoxon signed rank tests, and Bland-Altman plots were used. RESULTS: Interrater reliability ratings for DIs had substantial intraclass correlations (ICC = 0.94) but not acceptable exact percent agreement (80.2%); DI and PW energy consumed were significantly correlated (r = 0.96, P < 0.001); DI slightly underestimated energy consumed compared with PW (Mdiff = -1.61 kcals, P < 0.001). Bland-Altman plots showed high DI-PW correspondence across various energy amounts and revealed few outliers. Energy left over by BC was highly correlated with DI (r = 0.87, P < 0.001) and PW (r = 0.90, P < 0.001); and mean differences were not significantly different from DI (Mdiff = 9.77 kcal, P = 0.06) or PW (Mdiff = -2.84 kcal, P = 0.20). CONCLUSIONS: Correspondence was high between PW and DI assessments of energy consumed, and high with BC energy left over. Results demonstrate reliability and practical validity of digital images for assessing child meal consumption in QSR settings.

Using a Marketing Evaluation Tool to Optimize a Social Marketing Campaign: Insights From a Copy Test of a You're the Mom Campaign Ad.

A copy test is a business tool for assessing advertisements. This report provides an example of how copy test may be used within nutrition education practice and research. A public health nutrition advertisement for You're the Mom was copy tested with a market research firm. Mothers (n = 300) were aged 22-49years, had a household income <$50,000 and ≥1 child aged 4-8years and bought fast food ≥2-3times/mo. Compared with advertisements for for-profit goods, the advertisement scored high on impact (77th percentile) and moderate on persuasiveness (46th percentile) and communicated 2 key messages at higher rates than norms (51% and 46%) and a third at a lower rate (37%). Copy test results can best inform campaign development when the distinct purpose of the ad (versus the overall campaign) is clear; and when evaluation tools are designed to align directly with that purpose.

Inflammatory response after neonatal cardiac surgery and its relationship to clinical outcomes.

BACKGROUND: Cardiac surgery in infants results in a profound inflammatory response secondary to cardiopulmonary bypass (CPB) and the need for blood products. It is not clear how this inflammatory response modulates postoperative course or whether quantification of proinflammatory cytokines can aid with risk stratification. In this study, we prospectively assessed a panel of candidate markers to determine the time course for inflammation and the association of specific markers with clinical outcomes defined as intensive care unit length of stay (LOS). METHODS: We obtained preoperative blood samples from 92 neonates undergoing surgery with CPB and then serially for 5 days after surgery. Numerous interleukins were assayed along with tumor necrosis factor (TNF)-alpha and interferon (INF)-gamma. The most common surgical procedures were arterial switch procedure (n = 35) and Norwood operation (n = 34). Multivariate analysis was performed to determine if inflammatory mediators could independently predict prolonged intensive care unit LOS. RESULTS: Compared with the presurgery level, there were statistically significant increases (p < 0.005) for 8 out of 11 inflammatory markers: INF-gamma, interleukin (IL)-10, IL-13, IL-2, IL-5, IL-8, TNF-alpha, and IL-6 after surgery. The only cytokine on the first postoperative day that was independently associated with prolonged length of stay was IL-8 (p = 0.002). Cytokine values measured on postoperative day 3 were most valuable in predicting prolonged LOS. A model that included use of circulatory arrest, and day 3 measures of IL-6 and IL-8 yielded an area under of the curve of 0.88 (95% confidence interval 0.79 to 0.96) for predicting a prolonged LOS. CONCLUSIONS: In summary, neonatal heart surgery for complex lesions elicits a broad inflammatory response. This early inflammatory response appears nonspecific and did not predict clinical course. Persistence of specific inflammatory mediators on the third day after surgery, however, provided important prognostic information. As such, select cytokines may serve as valuable biomarkers in this population. Whether strategies targeting specific cytokines can alter clinical course is not known.
