Title: efficacy of a food parenting intervention for mothers with low income to reduce preschooler's solid fat and added sugar intakes: a randomized controlled trial

Effectiveness of a food literacy and positive feeding practices program for parents of 0 to 5 years olds in Western Australia

ISSUE ADDRESSED

Lifelong eating behaviours are established in childhood. Improving parents' food literacy skills is essential, as parents play a fundamental role in establishing their children's healthy eating behaviours and preferences for nutritious food. This paper describes the development and evaluation of an innovative program that combines food literacy with positive parent feeding practices, targeting parents in disadvantaged areas of Western Australia.

METHODS

The Food Sensations® for Parents five-week program was delivered to participants from community-based parenting organisations during 2020 and 2021. Formative research and a pre-post evaluation design were adopted.

RESULTS

Pre- and post-evaluation data were collected from 224 participants (96% female). There was a statistically significant improvement in the mean score for 13 food literacy behaviours, 10 positive parenting feeding practices and a mean increase in parents' daily vegetable intake of 1/3 serve. Participants reported significantly greater net improvements in food literacy behaviours than feeding practices, the largest being the Use a nutrition information panel to make food choices (33.1%). Multivariate logistic regression analyses found English as a first language, being older than 35, and from a higher Socio-Economic Index for Areas resulted in a higher likelihood of positive changes in behaviours and practices.

CONCLUSIONS

The findings indicate that the program is effective in improving the frequency of use of food literacy behaviours, positive parenting feeding practices and increasing vegetable consumption. SO WHAT?: Analysing improvements in food literacy behaviours and feeding practices provides clarity on what change can be expected with a five-week parent program.

Systems map of interventions to improve dietary intake of pre-school aged children: A scoping review

Implementation and sustaining impact of early childhood nutrition interventions in practice remains a challenge. An understanding of the extent to which determinants across multiple levels of the food system are being addressed may improve success. This literature review aimed to synthesise the evidence on interventions targeting dietary intake and eating behaviours in preschool children using a systems approach. Eligible studies included intervention studies targeting the dietary intake of preschool children aged 2-5 years in high income countries, published in English after January 2000. Interventions were categorised to the Determinants of Nutrition and Eating (DONE) framework for children developed and evaluated by experts across multiple fields. The framework maps and ranks 411 factors driving eating behaviours and nutrition and can be used to systematically summarise determinants. DONE ranks each determinant for its perceived research priority. A total of 160 eligible studies were identified. Most interventions targeted interpersonal (n = 101, 63.1%) and individual (n = 85, 53.1%) level determinants, with fewer targeting environmental (n = 55, 34.4%) and policy level (n = 17, 10.6%) determinants. The most frequently addressed determinants were Parental Resources and Risk Factors (n = 85) and Children's Food Knowledge, Skills and Abilities (n = 67). These determinants had a Moderate research priority rating. Home Food Availability and Accessibility at the environmental level is classified as the highest research priority, however, only 15 of 160 interventions addressed this determinant. This review highlights home food availability and accessibility as potential leverage points for future interventions to improve children's dietary intake and eating behaviours.

Eating Behaviours, Oral Hygiene, and Caries in a Population of Spanish Children with Divorced Parents: A Cross-Sectional Study

Dental caries are a public health problem that is influenced by dietary habits. This cross-sectional study aimed to investigate the feeding and hygiene habits that divorced parents exercise over their children compared to non-divorced parents, and how this may influence the rate of caries in their children. The data of participants (n = 174) with an average age of 12.17 ± 2.04 years were examined to assess the mean decayed/missing/filled teeth (DMFT) index, and they were asked questions about their oral hygiene habits. At the same time, their parents answered the parental feeding style questionnaire. A moderation analysis was conducted with family control of oral hygiene habit levels as an independent variable, decayed teeth as a dependent variable, and feeding control as a moderating variable. Results showed that divorced parents were found to have more problems in controlling their children's hygiene and dietary habits, have less control over their children's feeding, and make more use of instrumental feeding, which led to children of divorced parents having more caries. Despite the limitations linked to the cross-sectional design of the study and considering both the convenience sample and the impossibility of controlling for all aetiological factors linked to the development of caries, it can be concluded that children of divorced parents have an increased risk of tooth decay. However, parental controlled feeding interferes with the effect of family controlled oral hygiene habits on the decayed tooth, decreasing the rate of caries.

Healthy Snacks and Drinks for Toddlers: A Qualitative Study of Caregivers' Understanding of Expert Recommendations and Perceived Barriers to Adherence

BACKGROUND

Despite expert recommendations, most toddlers consume sugary drinks and more sweet and salty snack foods than fruits and vegetables as snacks. Studies have examined toddler caregivers' reasons for providing sugary drinks, but few have examined the reasons for providing nutritionally poor snack foods.

METHODS

Researchers conducted focus groups in one low-income community to assess caregivers' familiarity, understanding and attitudes regarding healthy drink and snack recommendations for toddlers. A convenience sample of 24 caregivers of toddlers (12-36 months) participated. Researchers conducted a descriptive analysis of the participants' familiarity with recommendations and a thematic analysis of the barriers to adherence.

RESULTS

Most participants were familiar with recommendations, but many were surprised that some drinks and snack foods are not recommended, and most believed recommendations were not realistic. Common barriers to adhering to recommendations included beliefs about their child's innate preferences, family modeling and others' provision of drinks and snacks in and outside the home. Practical barriers included the higher cost and inconvenience of serving fruits and vegetables on-the-go.

CONCLUSION

Similar barriers limited caregivers' adherence to expert recommendations about healthy snacks and drinks for toddlers. Nutrition education interventions should provide practical strategies for addressing these barriers and enlist childcare and health providers to reinforce recommendations.

Results from the Strong Families Start at Home/Familias Fuertes Comienzan en Casa: feasibility randomised control trial to improve the diet quality of low-income, predominantly Hispanic/Latinx children

OBJECTIVE

To describe the feasibility, acceptability and results of Strong Families Start at Home, a 6-month pilot trial of a home-based food parenting/nutrition intervention.

DESIGN

Pilot randomised controlled trial.

SETTING

Participants received six visits with a community health worker trained in motivational interviewing (three home visits, three phone calls); an in-home cooking or reading activity; personalised feedback on a recorded family meal or reading activity; text messages and tailored printed materials.

PARTICIPANTS

Parents and their 2-5-year-old child were randomised into intervention (responsive food parenting practices/nutrition) or control (reading readiness) groups.

RESULTS

Parents (n 63) were mostly mothers (90 %), Hispanic/Latinx (87 %), born outside the USA (62 %), with household incomes <$25 k (54 %). Despite delivery during COVID-19, 63 % of dyads were retained at 6 months. The intervention was delivered with high fidelity. All parents in the intervention group (n 24) expressed high levels of satisfaction with the intervention, which produced positive treatment effects for whole and total fruit component Healthy Eating Index-2015 scores (point estimate (PE) = 2·14, 95 % CI (0·17, 1·48); PE = 1·71, 95 % CI (0·16, 1·47), respectively) and negative treatment effects for sodium (PE = -2·09, 95 % CI (-1·35, -0·04)). Positive treatment effects also resulted for the following food parenting practices: regular timing of meals and snacks (PE = 1·08, 95 % CI (0·61, 2·00)), reducing distractions during mealtimes (PE = -0·79, 95 % CI (-1·52, -0·19)), using food as a reward (PE = -0·54, 95 % CI (-1·35, -0·04)) and providing a supportive meal environment (PE = 0·73, 95 % CI (0·18, 1·51)).

CONCLUSION

Given the continued disparities in diet quality among low-income and diverse families, continued efforts to improve child diet quality in fully powered intervention trials are needed.

Asia-Pacific consensus statement on integrated 24-hour activity guidelines for the early years

Background

Early childhood is a vital period for development and growth. Promoting beneficial lifestyle behaviours in early childhood can help optimise children's health, development and learning, shape their behaviours in adulthood and offer the best protection against future non-communicable diseases (NCDs). In the Asia-Pacific region, NCDs are significant causes of healthcare burden and mortality. Furthermore, there is also a high prevalence of adverse metabolic risk factors and unhealthy lifestyle behaviours among these children.

Method

Representatives from 19 Asia-Pacific nations and/or jurisdictions developed a consensus statement on integrated 24-hour activity guidelines for the early years using the GRADE-ADOLOPMENT framework.

Findings

These guidelines apply to all infants, toddlers and pre-schoolers below 5 years of age. The guidelines aim to provide a holistic and practical approach to lifestyle activities by framing physical activity, sedentary behaviour and sleep within a 24-hour period. Dietary patterns were included as they play an integral role in metabolic health and energy balance.

Interpretation

Aligned with the World Health Organization's Global Action Plan for the Prevention and Control of NCDs through health promotion interventions in early life, through cultivating healthy lifestyle behaviours in the children's early years, we aim to provide children with the best start in life and reduce the burden of future NCDs in the Asia-Pacific region.

Funding

Funded by Integrated platform for research in advancing metabolic health outcomes of women and children.

A Narrative Review of Dietary Assessment Tools for Preschool-Aged Children in the Home Environment

Preschool-aged children in the U.S. have suboptimal diets. Interventions to improve child nutrition focus on parents and their role in shaping social and physical home environments, which influence children's eating behaviors. Dietary assessment tools selected to measure intervention objectives, and how results are interpreted in key findings, are essential when examining children's diets. The objectives of this review were to (1) describe dietary assessment tools used in intervention studies in young children focused within the home environment; and (2) examine how the application of these dietary assessment tools addressed intervention objectives. PubMed and Web of Science were searched for English-language nutrition intervention studies that included children aged 2-5 years, had a home environment component, used a dietary assessment tool, and reported on diet-related outcomes. Seventeen studies were included. Intervention objectives focused on overall diet, specific food groups, eating occasions, and obesity prevention/treatment. Concordance of key findings with intervention objectives, type of tool used, and multiple tools within the same study varied with 8 studies aligning in objective and tool, 1 discordant in both, and 8 partially concordant or too broad to determine. This review highlights current challenges in measuring dietary intake in preschoolers and provides recommendations for alternative applications and strategies.

Exploring the application of behaviour change technique taxonomies in childhood obesity prevention interventions: A systematic scoping review

•

Novel critique of BCT taxonomy applications in childhood obesity prevention trials.

•

Large variation in BCT methods and reporting of BCT-related methods and results.

•

Scarce detail reported in selection of BCTs in prospective taxonomy applications.

•

Need for guidance to standardise processes and reporting of taxonomy applications.

Behaviour change technique (BCT) taxonomies provide one approach to unpack the complexity of childhood obesity prevention interventions. This scoping review sought to examine how BCT taxonomies have been applied to understand childhood obesity prevention interventions targeting children aged 12 years or under and/or their caregivers. A systematic search was conducted in Medline, Embase, PsycINFO, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, CINAHL and PROSPERO, to capture all eligible research up to February 2021. No limits were placed on country, language, publication dates, or full text availability. Eligible studies included any study design that applied a BCT taxonomy and evaluated behavioural childhood obesity prevention interventions targeting children aged 12 years or under and/or their parents or caregivers. Sixty-three records, describing 54 discrete studies were included; 32 applied a BCT taxonomy prospectively (i.e., to design interventions) and 23 retrospectively (i.e., to assess interventions), 1 study did both. There was substantial variation in the methods used to apply BCT taxonomies and to report BCT-related methods and results. There was a paucity of detail reported in how BCTs were selected in studies applying BCT taxonomies prospectively. Our review provides important insight into the application of BCT taxonomies in childhood obesity prevention and several ongoing challenges, pointing to the need for best practice reporting guidance.

Parent and child dietary changes in a 6-month mobile-delivered weight loss intervention with tailored messaging for parents

Objective

To examine changes in parent and child dietary intake, associations between program adherence and parent dietary changes, and the association between parent and child dietary changes in a mobile-delivered weight loss intervention for parents with personalized messaging.

Methods

Adults with overweight or obesity and who had a child aged 2-12 in the home were recruited for a randomized controlled trial comparing two types of dietary monitoring: calorie monitoring (Standard, n = 37) or "red" food monitoring (Simplified, n = 35). Parents received an intervention delivered via a smartphone application with lessons, text messages, and weekly personalized feedback, and self-monitoring of diet, activity, and weight. To measure associations between parent and child dietary changes, two 24-h recalls for parents and children at baseline and 6 months measured average daily calories, percent of calories from fat, vegetables, fruit, protein, dairy, whole grains, refined grains, added sugars, percent of calories from added sugars, and total Healthy Eating Index-2015 score.

Results

Higher parent engagement was associated with lower parent percent of calories from fat, and greater days meeting the dietary goal was associated with lower parent daily calories and refined grains. Adjusting for child age, number of children in the home, parent baseline BMI, and treatment group, there were significant positive associations between parent and child daily calories, whole grains, and refined grains. Parent-child dietary associations were not moderated by treatment group.

Conclusions

These results suggest that parent dietary changes in an adult weight loss program may indirectly influence child diet.

Preventing and treating childhood overweight and obesity in children up to 5 years old: A systematic review by intervention setting

The prevalence of childhood obesity is increasing worldwide with long-term health consequences. Effective strategies to stem the rising childhood obesity rates are needed but systematic reviews of interventions have reported inconsistent effects. Evaluation of interventions could provide more practically relevant information when considered in the context of the setting in which the intervention was delivered. This systematic review has evaluated diet and physical activity interventions aimed at reducing obesity in children, from birth to 5 years old, by intervention setting. A systematic review of the literature, consistent with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, was performed. Three electronic databases were searched from 2010 up to December 2020 for randomised controlled trials aiming to prevent or treat childhood obesity in children up to 5 years old. The studies were stratified according to the setting in which the intervention was conducted. Twenty-eight studies were identified and included interventions in childcare/school (n = 11), home (n = 5), community (n = 5), hospital (n = 4), e-health (n = 2) and mixed (n = 1) settings. Thirteen (46%) interventions led to improvements in childhood obesity measures, including body mass index z-score and body fat percentage, 12 of which included both parental/family-based interventions in conjunction with modifying the child's diet and physical activity behaviours. Home-based interventions were identified as the most effective setting as four out of five studies reported significant changes in the child's weight outcomes. Interventions conducted in the home setting and those which included parents/families were effective in preventing childhood obesity. These findings should be considered when developing optimal strategies for the prevention of childhood obesity.

Family‐based interventions for preventing overweight or obesity among preschoolers from racial/ethnic minority groups: A scoping review

Objective

This scoping review aimed to synthesize the published literature on family‐based childhood obesity prevention interventions from 2015 to 2021 that focused on children 2–5 years of age from racial and/or ethnic minority households.

Methods

A PICOS (population, intervention, comparison, outcome, and setting) framework was used to guide the development of the research question, search strategy, and inclusion/exclusion criteria. To be included, the study must have been a randomized controlled trial or quasi‐experimental trial that enrolled participants 2–5 years of age and their caregivers who identified as being from a racial and/or ethnic minority group in the United States. The study must have also examined a family‐based intervention that incorporated components to prevent childhood obesity (i.e., fruits and vegetable intake, parental responsive feeding, physical activity), be conducted in a remote (i.e., online, text, mail), home, community, primary care setting, or early childhood education institution setting, and report on body mass index (BMI, kg/m²), BMI z‐score, anthropometric measures (weight, waist circumference, fat mass, etc.), changes in health behaviors, or increase in nutritional knowledge.

Results

Fourteen individual studies were identified. Most interventions used multiple components for promoting nutritional knowledge and behavioral changes among families. Eight interventions included culturally tailored components targeting four aspects: (1) language barriers, (2) food choices, (3) relationships between family members, and (4) rapport building.

Conclusions

There is limited research in this field focusing on children from racial and/or ethnic minority groups. Future efforts should invest in developing culturally appropriate interventions for these groups.

Parental Feeding Practices in Families Experiencing Food Insecurity: A Scoping Review

Parental feeding practices and styles influence child diet quality and growth. The extent to which these factors have been assessed in the context of disadvantage, particularly household food insecurity (HFI), is unknown. This is important, as interventions designed to increase responsive practices and styles may not consider the unique needs of families with HFI. To address this gap, a scoping review of studies published from 1990 to July 2021 in three electronic databases was conducted. A priori inclusion criteria were, population: families with children aged 0–5 years experiencing food insecurity and/or disadvantage; concept: parental feeding practices/behaviours/style; and context: high income countries. The search identified 12,950 unique papers, 504 full-text articles were screened and 131 met the inclusion criteria. Almost all the studies (91%) were conducted in the United States with recruitment via existing programs for families on low incomes. Only 27 papers assessed feeding practices or styles in the context of HFI. Of the eleven interventions identified, two assessed the proportion of participants who were food insecure. More research is required in families outside of the United States, with an emphasis on comprehensive and valid measures of HFI and feeding practices. Intervention design should be sensitive to factors associated with poverty, including food insecurity.

Parental Food Communication and Child Eating Behaviours: A Systematic Literature Review

AIM

To review current evidence for parental food communication practices and their association with child eating behaviours.

METHODS

The PRISMA framework guided the reporting of the review; registered with Prospero in July 2020 (blinded for peer review). Eligible studies were critically appraised using the Joanna Briggs Institute tools. Only quantitative studies that included a parental measure of food communication and a child measure of eating behaviour were included.

RESULTS

From 11063 articles 23 were eligible for synthesis. The vast majority (82%) of studies used observational cross-sectional designs. Three involved observing parent-child dyads, with the remainder using questionnaires. Two quasi-experimental designs tested interventions and two randomised control trial were reported. The majority of measures assessing parental food communication were subscales of larger questionnaires. The Caregiver's Feeding Style Questionnaire (CFSQ) was the most direct and relevant measure of parental food communication. Findings of reviewed studies highlighted that "how" parents communicate about food appears to impact child eating behaviours. Using child-centred communication provided promising outcomes for positive child eating behaviours, while parental "diet" communication was found to be associated with poorer dietary outcomes in children.

CONCLUSIONS

Food communication research is in its infancy. However, evidence for the importance of parents' child-focused food communication is emerging, providing a focus for future research and interventions. SO WHAT?: Given the gaps in our understanding about prevention of disordered eating, there is a significant opportunity to explore what food communication strategies may assist parents to communicate about food in a positive way.

Development of a Food Frequency Questionnaire for Assessing Habitual Intake of Free Sugar Among Children in Saudi Arabia

The World Health Organization emphasizes the urgency to assess and limit the intake of free sugar (FS) among individuals in order to prevent several non-communicable diseases. However, data regarding intake of FS are lacking in Saudi Arabia and in the Middle East. A reliable valid tool is needed to assess children's habitual intake of FS. Thus, we aimed to develop and validate a food frequency questionnaire (FFQ) that assesses children's habitual intake of FS in Saudi Arabia. In this cross-sectional study, 424 healthy Saudi children ages 6–12 years were included using river sampling method. Sociodemographic data and contact information were collected from mothers using an online survey. Dietary data were collected using 24-h dietary recalls (reference method) and a semi-quantitative FFQ through phone interviews. Items and food groups included in the initial draft of the FFQ were adopted from previous work. Content validity was done to the FFQ with total of 12 food groups and 41 food items. Next, a pilot study was conducted to estimate the sample size needed for the study and to ensure that all items reported in the 24-h dietary recalls were included in the final draft of the FFQ. Finally, data were collected to assess the validity and reliability of the FFQ at the population level. Mean intake of FS assessed by the FFQ was significantly higher than that assessed by the 24-h dietary recalls. Spearman's correlation between total FS assessed by the FFQ and 24-h dietary recall was positively low (rs = 0.30, p &lt; 0.001). The coefficient alpha indicated an acceptable level of internal consistency (α = 0.74, p &lt; 0.001). Test-retest reliability for total FS intake assessed by the FFQ was positively high (rs = 0.82). A slight agreement between FS intake assessed by the FFQ and the 24-h dietary recall was seen among the study sample (κ = 0.21, p &lt; 0.001). The newly developed FFQ was found to be reasonably valid in assessing children's habitual intake of FS in Saudi Arabia. Validating the instrument among older population in Saudi Arabia is warranted.

Parental feeding and childhood genetic risk for obesity: exploring hypothetical interventions with causal inference methods

BACKGROUND

Parental-feeding behaviors are common intervention targets for childhood obesity, but often only deliver small changes. Childhood BMI is partly driven by genetic effects, and the extent to which parental-feeding interventions can mediate child genetic liability is not known. Here we aim to examine how potential interventions on parental-feeding behaviors can mitigate some of the association between child genetic liability and BMI in early adolescence, using causal inference methods.

METHODS

Data from the Avon Longitudinal Study of Parents and Children were used to estimate an interventional disparity measure for a child polygenic score for BMI (PGS-BMI) on BMI at 12 years. The approach compares counterfactual outcomes for different hypothetical interventions on parental-feeding styles applied when children are 10-11 years (n = 4248). Results are presented as adjusted total association (Adj-Ta) between genetic liability (PGS-BMI) and BMI at 12 years, versus the interventional disparity measure-direct effect (IDM-DE), which represents the association that would remain, had we intervened on parental-feeding under different scenarios.

RESULTS

For children in the top quintile of genetic liability, an intervention shifting parental feeding to the levels of children with lowest genetic risk, resulted in a difference of 0.81 kg/m² in BMI at 12 years (Adj-Ta = 3.27, 95% CI: 3.04, 3.49; versus IDM-DE = 2.46, 95% CI: 2.24, 2.67).

CONCLUSIONS

Findings suggest that parental-feeding interventions have the potential to buffer some of the genetic liability for childhood obesity. Further, we highlight a novel way to analyze potential interventions for health conditions only using secondary data analyses, by combining methodology from statistical genetics and social epidemiology.

Occasions, purposes, and contexts for offering snacks to preschool-aged children: Schemas of caregivers with low-income backgrounds

OBJECTIVE

Snacking among preschool aged children is nearly universal and has been associated with overconsumed nutrients, particularly solid fats and added sugars (SoFAS). This research examined caregivers' schemas, or cognitive frameworks, for offering snacks to preschool-aged children.

METHODS

A qualitative design utilizing card sort methods was employed. Participants were 59 Black, Hispanic, and White caregivers of children aged 3-5 years with low-income backgrounds. Caregivers sorted 63 cards with images of commonly consumed foods/beverages by preschool-aged children in three separate card sorts to characterize snacking occasions, purposes, and contexts. The mean SoFAS content (kcal/100 g) of foods/beverages was evaluated by occasions (snacks vs. not-snacks), purposes, and contexts.

RESULTS

Just under two-thirds (38/63 food cards) of foods/beverages were classified as snacks with moderate to high agreement. Snacks were offered for non-nutritive (e.g., requests, rewards) and nutritive (e.g., hunger/thirst) purposes in routine (e.g., home, school) and social contexts (e.g., with grandparents). Snacks offered for non-nutritive purposes and in social contexts were higher in SoFAS than those offered for nutritive reasons and in routine contexts.

CONCLUSIONS

Caregivers of young children offered various types of foods/beverages as snacks, with higher SoFAS snacks given for non-nutritive purposes and in social contexts. Understanding of caregivers' schemas for offering snacks to young children may inform targets for obesity prevention and anticipatory guidance to promote the development of healthful eating behaviors.

Effectiveness of healthy eating interventions among children: A quantitative systematic review

AIMS

This review aimed to evaluate the effectiveness of healthy eating interventions among normal-weight children.

DESIGN

A systematic review of randomized controlled trials.

DATA SOURCES

Seven databases were searched from the inception of each database until September 2019.

REVIEW METHODS

A systematic review of quantitative studies was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the PRISMA extension for reporting a synthesis without a meta-analysis.

RESULTS

Fifteen studies were included in this review. A meta-analysis could not be conducted because of the observed heterogeneity across studies. There were mixed effects of the included interventions on healthy eating habits, ranging from effective to not effective. Only a few studies found behavioural determinants effective in enhancing healthy eating.

CONCLUSION

Because of the observed heterogeneity and varied outcome variables, a meta-analysis could not be conducted, and the overall effectiveness of the included interventions could not be verified. Interventions that were theory based, parent focused, and delivered through the multimodal interactive approach were found to be effective in enhancing healthy eating habits among children. More studies involving peers that are institution based need to be conducted.

Fathers' food parenting: A scoping review of the literature from 1990 to 2019

BACKGROUND

While food parenting is a robust area of inquiry, studies have largely focused on mothers. Given the diversity of family structures today and increases in fathers' engagement in caregiving, fathers' food parenting warrants attention.

OBJECTIVE

We present a scoping review of research on fathers' food parenting (1990-2019). Eligible studies included peer-reviewed research published in English documenting fathers' food parenting and presenting results for fathers separate from mothers.

RESULTS

Seventy-seven eligible studies were identified. Most studies were based in the U.S (63.6%) and utilized a cross-sectional design (93.5%). Approximately half of studies used a validated measure of food parenting (54.5%) and slightly less than 30% utilized theory (28.6%). Many studies did not report information on fathers' residential status (37.7%) or their relationship to the target child (biological vs social) (63.6%). Content analysis of study findings showed that: fathers are involved in food parenting, but at lower levels than mothers; there are few consistent mother-father differences in food parenting practices; and fathers' controlling food parenting is linked with negative nutrition outcomes in children while responsive food parenting is linked with positive child outcomes.

CONCLUSION

To better inform family interventions to prevent childhood obesity, future food parenting research with fathers should recognize the diversity of family structures and utilize prospective, theory-based, designs.

Positive parenting approaches and their association with child eating and weight: A narrative review from infancy to adolescence

Parents play a critical role in the development of children's eating behaviours and weight status, serving as providers, models and regulators of the food environment. Many research reviews have focused on the robust body of evidence on coercive control in feeding: how parenting practices such as restriction and pressure to eat increase children's risk for developing undesirable eating behaviours and unhealthy weight outcomes. Fewer reviews adopt a strengths-based perspective focusing on the ways that parents can actively support the development of healthy eating behaviours and weight trajectories. Emerging research on such positive parenting styles and practices offers solutions beyond the avoidance of coercive control, as well as opportunities to highlight parallels between research on food parenting and the broader, well-established developmental literature on positive parenting. The focus of this review is to summarize what is known regarding benefits of positive parenting styles and practices for child eating and weight outcomes and discuss recommendations for future research. Current evidence supports starting with responsive feeding and parenting during infancy and incorporating structure and limit setting in early childhood, with monitoring and mealtime structure remaining important during middle childhood and adolescence. Areas for future research include: (1) further examination of the implications of identified food parenting practices and styles among diverse groups and caregivers; (2) increased consideration of child factors (eg, temperament) as moderators or mediators; and (3) further clarification of the relationship between general parenting and food parenting.

Childhood Obesity Evidence Base Project: A Systematic Review and Meta-Analysis of a New Taxonomy of Intervention Components to Improve Weight Status in Children 2-5 Years of Age, 2005-2019

Objective: To evaluate the efficacy of childhood obesity interventions and conduct a taxonomy of intervention components that are most effective in changing obesity-related health outcomes in children 2-5 years of age. Methods: Comprehensive searches located 51 studies from 18,335 unique records. Eligible studies: (1) assessed children aged 2-5, living in the United States; (2) evaluated an intervention to improve weight status; (3) identified a same-aged comparison group; (4) measured BMI; and (5) were available between January 2005 and August 2019. Coders extracted study, sample, and intervention characteristics. Effect sizes [ESs; and 95% confidence intervals (CIs)] were calculated by using random-effects models. Meta-regression was used to determine which intervention components explain variability in ESs. Results: Included were 51 studies evaluating 58 interventions (N = 29,085; mean age = 4 years; 50% girls). Relative to controls, children receiving an intervention had a lower BMI at the end of the intervention (g = 0.10, 95% CI = 0.02-0.18; k = 55) and at the last follow-up (g = 0.17, 95% CI = 0.04-0.30; k = 14; range = 18-143 weeks). Three intervention components moderated efficacy: engage caregivers in praise/encouragement for positive health-related behavior; provide education about the importance of screen time reduction to caregivers; and engage pediatricians/health care providers. Conclusions: Early childhood obesity interventions are effective in reducing BMI in preschool children. Our findings suggest that facilitating caregiver education about the importance of screen time reduction may be an important strategy in reducing early childhood obesity.

Economic hardship and child intake of foods high in saturated fats and added sugars: the mediating role of parenting stress among high-risk families

OBJECTIVE

Economic hardship (EH) may link to poorer child diet, however whether this association is due to resource limitations or effects on family functioning is unknown. This study examines whether parenting stress mediates the association between EH and child consumption of foods high in saturated fats and added sugars (SFAS).

DESIGN

Data were collected from the Fragile Families and Child Wellbeing study. EH was assessed using eight items collected when children were between 1-9 years old. Mothers reported parenting stress and frequency of child consumption of high SFAS foods when children were 9 years old. Latent growth curve modelling (LGCM) and structural equation modelling tested direct associations between the starting level/rate of change in EH and high SFAS food consumption, and parenting stress as a mediator of the association.

SETTING

Twenty US cities.

PARTICIPANTS

Mothers/children (n 3846) followed birth through age 9 years, oversampled 'high-risk', unmarried mothers.

RESULTS

LGCM indicated a curvilinear trend in EH from ages 1-9, with steeper increases from ages 3-9 years. EH did not directly predict the frequency of high SFAS foods. Average EH at 3 and 5 years and change in EH from ages 1-9 predicted higher parenting stress, which in turn predicted more frequent consumption of high SFAS foods.

CONCLUSIONS

Findings suggest it may be important to consider parenting stress in early prevention efforts given potential lasting effects of early life EH on child consumption of high SFAS foods. Future research should explore how supports and resources may buffer effects of EH-related stress on parents and children.

Interventions to increase the consumption of water among children: A systematic review and meta-analysis

The aim of this study was to conduct a systematic review and meta-analysis on the effectiveness of interventions to increase children's water consumption. A systematic literature search was conducted in seven electronic databases. Studies published in English before 18 February 2019 that evaluated any type of intervention that measured change in water consumption among children aged 2 to 12 years by applying any type of design were included. Of the 47 interventions included in the systematic review, 24 reported a statistically significant increase in water consumption. Twenty-four interventions (17 randomized controlled trials and seven studies with other controlled designs) were included in the meta-analysis. On average, children in intervention groups consumed 29 mL/d (confidence interval [CI] = 13-46 mL/d) more water than did children in control groups. This effect was larger in eight interventions focused specifically on diet (MD = 73 mL/d, CI = 20-126 mL/d) than in 16 interventions focused also on other lifestyle factors (MD = 15 mL/d, CI = 1-29 mL/d). Significant subgroup differences were also found by study setting and socioecological level targeted but not by children's age group, intervention strategy, or study design. In conclusion, there is evidence that, on average, lifestyle interventions can lead to small increases in children's daily water consumption. More research is needed to further understand the specific intervention elements that have the greatest effect.

Waist Circumference and Healthy Lifestyle Preferences/Knowledge Monitoring in a Preschool Obesity Prevention Program

Weight and body mass index (BMI) changes appear to be poor measures for assessing the success of most pediatric obesity prevention programs (POPP). The aim of this study is to evaluate the effectiveness of the preschool-age prevention program (3P) in improving and maintaining overtime preschoolers' knowledge/preferences about healthy nutrition and physical activity (PA), and the relationship between acquired healthy behaviors and anthropometrics including waist circumference (WC). Twenty-five preschoolers underwent a 24-month healthy lifestyle multi-component pilot intervention followed by a one-year wash-out period; 25 age-matched served as controls. Anthropometric/behavioral data were monitored. After the 2-year study and wash-out, the rates of children overweight and with obesity decreased only in the intervention group, where, also, normal-weight children with visceral obesity attained WC normal values (p = 0.048). While mean values of BMI Z-scores remained unchanged in both the intervention and control groups, WC (values and percentiles) showed a significant reduction only in the intervention group. Children's adherence to the Mediterranean diet remained acceptable among the entire sample. Although daily sweet beverage consumption remained unchanged in both groups, knowledge/preferences improved significantly more in the intervention group. In conclusion, WC may be more sensitive than BMI for monitoring preschoolers in POPP and reflects healthy behavioral changes acquired during the intervention.
