A measurement scale to assess responsive feeding among Cambodian young children

Development and validation of a tool to assess underlying factors of iron-rich food consumption among pregnant women

Anaemia among pregnant women remains a public health concern globally. One major cause of this persistent problem is iron deficiency, which may be the result of limited iron intake in the diet. Using the extended version of the theory of planned behaviour (eTPB), this study aims to develop and validate a questionnaire assessing psychosocial and environmental factors that could influence the consumption of iron-rich foods (IRFs) among Senegalese pregnant women. A three-step procedure was used. Six focus group discussions (FGDs) were held with 10 pregnant women each from a different region to identify salient beliefs related to each of the four constructs of the eTPB using a structured guide. Information from FGDs was used to develop a questionnaire, which was administered to the first group (n = 200) of pregnant women. Principal component analyses and exploratory factorial analyses were performed on the first set of data to identify latent factors for each construct namely the attitude, subjective norm and perceived behavioural control. A revised and shorter version of the questionnaire was administered to a second sample of pregnant women (n = 226) and confirmatory factorial analyses were conducted using this second set of data. Hancock and Muller's H reliability index was computed on the final model. The final questionnaire included 44 items. Most criteria for fit indices were met and H values were satisfactory. This study proposes a tool that could be used to explore determinants of the consumption of IRF among pregnant women. Further validation is still warranted in other contexts.

Observational Methods in Studies of Infant and Young Child Feeding Practices in Low- and Middle-Income Countries: A Twenty-Year Retrospective Review

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.

A Responsive Feeding Questionnaire Based on Self-Determination Theory for Caregivers of Chinese Toddlers

OBJECTIVE

To develop and test the psychometric properties of a responsive feeding questionnaire (RFQ) on the basis of Self-Determination Theory for caregivers of toddlers aged 12-24 months in China.

DESIGN

Item generation, preliminary evaluation items, refinement questionnaire, and psychometric properties testing.

SETTING

Toddlers' caregivers from Shandong Province, China, were surveyed online between June 2021 and February 2022 (n = 616).

MAIN OUTCOME MEASURE

Content, face, and construct validity and reliability of the RFQ.

ANALYSIS

Content validity was performed on the basis of expert panel feedback and cognitive interviews among caregivers. Construct validity was evaluated using principal component analysis with varimax rotation. Test-retest reliability was conducted with a sample of 105 caregivers.

RESULTS

Over 3 phases of testing, a new instrument was developed to measure responsive feeding in toddler caregivers. The instrument was reliable, with an internal consistency of 0.87 and an intraclass correlation of 0.92. The principal component analysis identified a 3-factor solution (autonomy support, positive involvement, appropriate response) aligning with a theoretical framework from Self-Determination Theory. The final version of the instrument included 23 items.

CONCLUSIONS AND IMPLICATIONS

The 23-item RFQ has been validated in a Chinese population. Future research needs to validate this instrument in other countries and with children of different ages.

Rethinking Responsive Feeding: Insights from Bangladesh

Young children’s growth is influenced by food and feeding behavior. Responsive feeding has been shown to promote healthy growth and development, to prevent under- and overfeeding, and to encourage children’s self-regulation. However, most measures of responsive feeding do not incorporate bidirectional mother-infant responsivity or early learning principles and have not been validated against observations. To overcome these gaps, we laid the groundwork for a responsive feeding measure based on a community sample of 67 mothers and their 6–18-month-old children in Bangladesh. Children were weighed and measured. Mothers reported on their child’s dietary intake and responded to a 38-item responsive feeding questionnaire developed through a 2-phase Delphi procedure. Based on a video-recorded feeding observation, mother-child dyads were categorized into proximal (43%) and distal (57%) responsivity groups. Using stepwise logistic regression, a 9-item model from the responsive feeding questionnaire had excellent fit (AUC = 0.93), sensitivity (90%), specificity (89%), positive predictive value (87%), and negative predictive value (93%). Proximal responsivity was characterized by maternal concerns about children’s dietary intake. Distal responsivity was characterized by maternal perception of children’s happy mood during feeding. Findings support responsive feeding as modulating between proximal and distal responsivity, promoting autonomy, self-regulation, and enabling children to acquire and practice healthy eating behaviors.

Observation of Traditional Caregiver-Infant Feeding Behaviours and Porridge and Energy Intakes during One Meal to Define Key Messages for Promoting Responsive Feeding in the Amparafaravola District, Rural Madagascar

Undernutrition is highly prevalent in young children in Madagascar and insufficient intake per meal could be one of the main causes. A cross-sectional survey of infant feeding practices including video-recorded meal observations was carried out with 101 caregiver-infant pairs in the Amparafaravola district, Northeast Madagascar. The objective was to quantify the porridge/energy intake of 9-11-month-old children and assess its association with the caregiver-infant feeding behaviours. Then, key messages for promoting responsive feeding (RF) were developed and tested through focus group discussions. The mean porridge intake was 12.8 ± 7.5 g/kg body weight (BW)/meal, corresponding to hardly one-third of the 300 kcal recommended from complementary foods for 9-11-month-old children. Analysis of meal videos suggested that mothers practiced the five positive feeding behaviours (self-feeding, responsive, active, social, and distraction), and rarely the negative ones. Only 6.9% of mothers used positive RF "very frequently", although it was associated with higher intakes (p < 0.05), with mean intake reaching 21 g/kg BW. In focus groups, caregivers approved the six RF messages and related counselling cards. They suggested some modifications to improve their understanding, and counselling cards were revised accordingly. The long-term impact of RF-promoting card use on the meal intakes and the nutritional status of young children must now be assessed.

Scoping review of nutrition intervention and dietary assessment studies in Khmer populations living in Cambodia

BACKGROUND

This scoping review aims to describe the body of nutrition intervention and dietary assessment research undertaken with Khmer populations in Cambodia, as well as summarise the nutrition knowledge base and highlight priority areas for future research.

METHODS

Five databases and the grey literature were searched, following PRISMA-ScR guidelines. Studies involving dietary assessment or nutrition interventions published after 1992 were identified using specific search terms and extracted to a customised data extraction table for categorisation and analysis. Study participants were Khmer people of any age and gender, living in rural or urban Cambodia.

RESULTS

Of the 100 included studies, 58 were dietary assessment only studies, 24 were nutrition interventions only, and 18 studies involved both assessment of intake and an intervention. Sixty-eight percent of study populations were mothers and young children, of which 52 studies focused on children aged under 5 years. Nineteen interventions involved supplementation and six trialled fortification of rice or fish sauce. Anaemia was the most common nutrition condition studied (n = 17), followed by malnutrition (n = 15) and malnutrition risk factors (n = 11). General nutrition status was explored in 25 studies, and individual micronutrients that were studied included iron (n = 27), zinc (n = 6), vitamin A (n = 4) and thiamine (n = 3).

CONCLUSIONS

Diet-related research in Khmer populations in Cambodia has predominantly focused on dietary assessment or evaluation of interventions aimed at reducing malnutrition and resolving micronutrient deficiencies. Areas identified as emerging needs included non-communicable diseases, the ageing population and non-iron deficiency anaemia.

Measuring Responsive Feeding in Sri Lanka: Development of the Responsive Feeding Practices Assessment Tool

OBJECTIVE

To develop and validate a tool focusing on responsive feeding (RF) practices among mothers and infants aged between 6 and 12 months in Sri Lanka.

DESIGN

A comprehensive review, an in-depth qualitative study, and a cross-sectional study were carried out.

SETTING

Anuradhapura District, Sri Lanka.

PARTICIPANTS

Sample of mother-infant pairs (n = 170).

VARIABLES MEASURED

Items were developed by extracting data from a previous in-depth qualitative study on RF, informed by currently available RF items.

ANALYSIS

Content validation was performed among experts using standard techniques, followed by cognitive interviews among mothers. Structural validity was assessed using principal component analysis. Test-retest reliability was done with a sample of 50 mothers.

RESULTS

Cognitive validation with mothers confirmed the applicability and comprehensiveness of the tool. The tool possessed good reliability with an intraclass correlation of 0.80 and internal consistency of 0.79. The principal component analysis showed a clear 3 factor solution. The 3 factors were interpreted as responsive communication during feeding, appropriate feeding, attentive to child's signals, and proactive preparation of the feeding environment. The final version of the tool consisted of 15 items.

CONCLUSIONS AND IMPLICATIONS

The 15-item Responsive Feeding Practices Assessment Tool is a valid tool to assess RF.

Responsive Feeding Recommendations: Harmonizing Integration into Dietary Guidelines for Infants and Young Children

Responsive feeding (RF) involves reciprocal nurturing feeding practices between the caregiver and the child that encourage the child to develop preferences for healthy foods and beverages and to eat autonomously. In this commentary, we summarize RF-related findings from a recent US National Academies of Sciences, Engineering, and Medicine (National Academies) consensus study report examining consistency in infant and young child feeding (IYCF) recommendations in guidelines from high-income countries, and we discuss implications for future IYCF guidelines. Although existing guidelines included generally consistent messages about several RF behaviors, such as the importance of encouraging self-feeding and self-regulation in infants and toddlers, they generally did not present the recommendations as part of a cohesive RF interdisciplinary framework. Moving forward, evidence-based RF recommendations should be routinely incorporated and identified in dietary guidance for IYCF based on a consensus definition of RF grounded in sound responsive parenting and feeding frameworks. We recommend replicating the National Academies' scoping review in low- and middle- income countries and mixed-methods implementation science research to improve our understanding of how best to disseminate and implement RF-related recommendations across settings (e.g., home and early care and education centers), taking the social determinants of health into account.

A measurement scale to assess responsive feeding among Cambodian young children

The caregiver-child interaction during mealtime, which refers to responsive feeding (RF), influences child's dietary intake. In Cambodia, given the level of malnutrition, getting better knowledge of RF among young children is essential, but to do so, using an appropriate assessment tool is necessary. We aim to develop and to validate a measurement tool to assess RF in two different situations (before and after an intervention) among children 6-23 months old. This research is part of a larger trial assessing the impact of nutrition education combined or not with the provision of complementary foods on child nutritional status. The "Opportunistic Observation Form" from the Process for the Promotion of Child Feeding package was used to collect data on RF through direct observations of child's meal episodes. Data were used to define an initial scale composed of four constructs and 15 indicators. Confirmatory factor analyses (CFA) and Hancock and Mueller's H reliability indices were computed to assess the validity and reliability of the scale. The final tool was applied to baseline and endline data. At baseline, the sample included 243 pairs and, at endline, 248 pairs. The final scale included two latent constructs (RF and active feeding) that comprise three indicators for active feeding and five for RF. Criteria for fit indices of CFA were met for both constructs though better at baseline. Reliability coefficients were above 0.80 for each construct at baseline and endline. This research proposes a scale that could be used to assess active feeding and RF. Further validation is warranted in different contexts.

Responsive Feeding, Infant Growth, and Postpartum Depressive Symptoms During 3 Months Postpartum

Responsive feeding is crucial to the formation of life-long healthy eating behavior. Few studies have examined maternal responsive feeding in early infancy among a Chinese population. This prospective study describes maternal responsive feeding and factors associated with maternal responsive feeding, with emphasis on infant growth and maternal depressive symptoms, during the first 3 months postpartum in Taiwan. From 2015 to 2017, 438 pregnant women were recruited and followed at 1 and 3 months postpartum. Maternal responsive feeding at 3 months was measured on a 10-item 5-point Likert-type scale. Maternal depressive symptoms were measured using the Edinburgh Postnatal Depression Scale with a cutoff score of 10. Infant growth was categorized into four groups based on weight-for-length Z scores from birth to 3 months: no change, increase but in the normal range, increase to overweight, and decrease to underweight. Multiple regression revealed that postpartum depressive symptoms, primipara, and decreased infant weight-for-length Z score were negatively associated with maternal responsive feeding, while exclusive breastfeeding and maternal age younger than 29 years were positively associated with maternal responsive feeding. Heath professionals should educate mothers on responsive feeding, with emphases on first-time and non-exclusive breastfeeding mothers, as well as those with depressive symptoms, advanced maternal age, and infants who are becoming underweight.

Can a pragmatic responsive feeding scale be developed and applied globally?

Responsive feeding (RF) has been recognized as necessary to prevent all forms of malnutrition including stunting and childhood obesity. Specific RF guidelines have been developed, but it is unclear how RF behaviours can be monitored systematically. Therefore, developing valid and reliable abbreviated and pragmatic RF scales is an important global priority. This is challenging, as RF is a construct with multiple dimensions including recognizing and responding to hunger and satiety cues, providing a nurturing environment during feeding episodes, and understanding how feeding needs evolve as a function of the developmental stage of the young child. Further, RF is embedded within the responsive parenting framework that in addition to RF includes sleep, soothing and play routines and the interconnections between them. A recent pioneer study conducted in a rural area of Cambodia validated an 8‐item RF scale through direct feeding observations of 6‐ to 23‐month‐old infants at home, as part of two cross‐sectional surveys conducted before and after a complementary feeding intervention. It is important for similar research to be conducted elsewhere to find out if it is possible or not to develop a core RF scale that is valid and reliable and that has adequate specificity and sensitivity for application in community studies and population surveys globally. As highlighted in this article, different definitions of RF have been used in the field; thus, it is important to reach consensus on a single definition to help move this research area forward.
