“…Despite these limitations, in contrast to a prior review that concentrated on responsive feeding behaviors exclusively, this review explores the application of observations for various IYCF behaviors [ 10 ]. Another strength of this review was the study team who has decades of combined experience using diverse observational methods to study child eating behaviors in both laboratory and field settings [ 23 , 69 , 70 , 71 , 72 ]. We believe that this level of expertise aided in the synthesis and interpretation of findings.…”

This narrative review describes the observational approaches used to study infant and young child feeding (IYCF) practices in low- and middle-income countries (LMICs) published between 2001 and 2021. Articles were included in this narrative review if they were (1) original peer-reviewed articles published in English in PubMed and Web of Science; (2) published between 1 January 2001, and 31 December 2021; (3) conducted in an LMIC; and (4) employed observations and focused on IYCF practices among children aged 6–59 months. The studies (n = 51) revealed a wide-ranging application of direct meal and full-day observations, as well as indirect spot checks, to study IYCF. The findings revealed that meal observations were typically conducted during a midday meal using precise recording approaches such as video and aimed to understand child–caregiver interactions or specialized nutritious food (SNF) usage. Conversely, full-day observations lasted between 6 and 12 h and often used a field notes-based recording approach. Behaviors occurring outside of mealtime, such as snacking or interhousehold food sharing, were also a primary focus. Finally, spot checks were conducted to indirectly assess SNF compliance during both announced and unannounced visits. This review highlights the adaptability of observations across contexts and their versatility when used as a primary data collection tool to help monitor and evaluate nutrition programs.

“…The use of continuous food weight measurement is uncommon in children ( 2 ) due, in part, to two key challenges. First, behavioral protocols required to continuously measure food weight during eating may be difficult for children to follow (e.g., not touching the plate) and restrict typical eating behaviors (e.g., playing with food).…”

“…Second, it is uncommon to use multi-item meals with Universal Eating Monitors ( 14 , 15 ) and the “drinkometer” requires the use of liquid meals ( 8 ). This limits the utility of these protocols in studies with children, where the standard is to serve multi-item meals ( 2 ). Some studies have utilized multiple scales or added observational coding to continuous weight measurement when using multi-item meals ( 16 , 17 ), however, this substantially increases researcher burden.…”

“…A possible solution is to use observational coding to characterize cumulative intake curves from bite timing and average bite size. Observational coding is common in studies of eating behavior ( 2 ). In the case of children, this approach commonly relies on recording the precise timing of each bite of food in the meal videos ( 2 ).…”

“…Observational coding is common in studies of eating behavior ( 2 ). In the case of children, this approach commonly relies on recording the precise timing of each bite of food in the meal videos ( 2 ). Although the size/weight of each bite can only be approximated from video, it remains unclear if average bite sizes can be used to accurately characterize cumulative intake curves.…”

IntroductionObservational coding of eating behaviors (e.g., bites, eating rate) captures behavioral characteristics but is limited in its ability to capture dynamic patterns (e.g., temporal changes) across a meal. While the Universal Eating Monitor captures dynamic patterns of eating through cumulative intake curves, it is not commonly used in children due to strict behavioral protocols. Therefore, the objective of this study was to test the ability of computational models to characterize cumulative intake curves from video-coded meals without the use of continuous meal weight measurement.MethodsCumulative intake curves were estimated using Kisslieff’s Quadratic model and Thomas’s logistic ordinary differential equation (LODE) model. To test if cumulative intake curves could be characterized from video-coded meals, three different types of data were simulated: (1) Constant Bite: simplified cumulative intake data; (2) Variable Bite: continuously measured meal weight data; and (3) Bite Measurement Error: video-coded meals that require the use of average bite size rather than measured bite size.ResultsPerformance did not differ by condition, which was assessed by examining model parameter recovery, goodness of fit, and prediction error. Therefore, the additional error incurred by using average bite size as one would with video-coded meals did not impact the ability to accurately estimate cumulative intake curves. While the Quadratic and LODE models were comparable in their ability to characterize cumulative intake curves, the LODE model parameters were more distinct than the Quadradic model. Greater distinctness suggests the LODE model may be more sensitive to individual differences in cumulative intake curves.DiscussionCharacterizing cumulative intake curves from video-coded meals expands our ability to capture dynamic patterns of eating behaviors in populations that are less amenable to strict protocols such as children and individuals with disordered eating. This will improve our ability to identify patterns of eating behavior associated with overconsumption and provide new opportunities for treatment.
