Title: UpdateonAnalyticalMethodsandResearchGaps intheUseofHouseholdConsumptionand ExpenditureSurveyDatatoInformtheDesignof Food-FortificationPrograms Authors: Adams, Katherine P; Vosti, Stephen A; Mbuya, Mduduzi NN; Friesen, Valerie M; Engle-Stone, Reina Abstract: The lack of nationally representative, individual-level dietary intake data has led researchers to increasingly turn to household-level data on food acquisitionsand/orconsumptiontoinformthedesignoffood-fortiﬁcationprogramsinlow-andmiddle-incomecountries(LMICs).Thesenationally representative, household-level data comefromhousehold consumptionand expenditure surveys (HCESs), which are collected regularly in many LMICs and are often made publicly available. Our objectives were to examine the utility of HCES data to inform the design of food-fortiﬁcation programsandtoidentifybest-practicemethodsforanalyzingHCESdataforthispurpose.Tothisend,wesummarizedinformationneededtodesign fortiﬁcation programs and assessed the extent to which HCES data can provide corresponding indicators. We concluded that HCES data are well suitedtoguidetheselectionofappropriatefoodvehicles,butbecauseindividual-levelestimatesofapparentnutrientintakesrelyonassumptions abouttheintrahouseholddistributionoffood,morecautionisadvisedwhenusingHCESdatatoselectthetargetmicronutrientcontentoffortiﬁed foods. We also developed a checklist to guide analysts throughthe use of HCES data and, where possible, identiﬁed research-based, best-practice analyticalmethodsforanalyzingHCESdata,includingselectingthenumberofdaysofrecalldatatoincludeintheanalysisandconvertingreported unitstostandardunits.Moreresearchisneededonhowbesttodealwithcompositefoods,foodsconsumedawayfromhome,andextremevalues, as well as the best methods for assessing the adequacy of apparent intakes.

EatingBehaviors,CaregiverFeedingInteractions, andDietaryPatternsofChildrenBornPreterm: ASystematicReviewandMeta-Analysis

Title: EatingBehaviors,CaregiverFeedingInteractions, andDietaryPatternsofChildrenBornPreterm: ASystematicReviewandMeta-Analysis Authors: Walton, Kathryn; Daniel, Allison I; Mahood, Quenby; Vaz, Simone; Law, Nicole; Unger, Sharon L; O’Connor, Deborah L Abstract: Infantsbornpreterm(<37weeksofgestation)oftenexperiencefeedingproblemsduringhospitalization.Whetherdiﬃcultiespersistorhavelongterm sequelae on childhood eating is unclear. We aimed to describe the oromotor eating skills (e.g., chewing/swallowing), eating behaviors (e.g., food neophobia), food parenting practices (e.g., pressure to eat), and dietary patterns of preterm children during late infancy (6–12 mo) and early childhood (>12 mo–7 y) and to determine whether these diﬀered from those of term-born peers. We identiﬁed 67 articles (57 unique studies) for inclusion.Weusedrandom-eﬀectsmeta-analysisofproportionstoexaminetheprevalenceoforomotoreatingskillandeatingbehaviorchallenges among preterm children, standard meta-analysis for comparisons with term-born peers, and the Grading of Recommendations, Assessment, Development and Evaluation approach to assess the certainty of evidence. Forty-three percent (95% CI: 24%, 62%) of infants and 25% (95% CI: 17%,33%)ofchildrenbornpretermexperiencedoromotoreatingdiﬃcultiesand16%(95%CI:4%,27%)and20%(95%CI:11%,28%),respectively, exhibitedchallengingeatingbehaviors.Duringlateinfancyandearlychildhood,oromotoreatingdiﬃculties(OR:2.86;95%CI:1.71,4.77;I2=67.8%) and challenging eating behaviors (OR: 1.52; 95% CI: 1.11, 2.10; I2 = 0.0%) were more common in those born preterm than in those born term: however, the certainty of evidence was very low. Owing to the low number and heterogeneity of studies, we narratively reviewed literature on food parenting and dietary patterns. Mothers of preterm infants appeared to have heightened anxiety while feeding and utilized coercive food parenting practices; their infants reportedly received less human milk, started solid foods earlier, and had poorer diet quality than term-born peers. In conclusion, meta-analyses show preterm children experience frequent oromotor eating diﬃculties and challenging eating behaviors throughout the early years. Given preterm birth increases risk of later obesity and diet-related chronic disease, research examining the eﬀects of caregiver–childinteractionsonsubsequentdietiswarranted.Thisreviewwasregisteredatwww.crd.york.ac.uk/prospero/asCRD42020176063
