A Structural Equation Modelling Approach to Understanding Influences of Maternal and Family Characteristics on Feeding Practices in Young Children

Sibship Composition and BMI Z-Score Among Saudi Preschoolers: A Cross-Sectional Study

Background and objective The association between sibship composition and child body mass index (BMI) has not been investigated in any Arab/Middle Eastern populations. In light of this, this study aimed to examine the association of the number of siblings, number of older siblings, and number of younger siblings with child BMI z-score (BMIz) among preschoolers in the Kingdom of Saudi Arabia (KSA). Methods A total of 209 mothers and their children were recruited from preschools in Jeddah, KSA. Mothers reported their responses to the study questionnaire via telephone. Child anthropometry was objectively measured; BMIz was calculated based on age- and sex-specific World Health Organization (WHO) growth standards and reference data. We used hierarchical multiple linear regression to examine the association between sibship composition variables and child BMIz, independent of the effect of potential confounders, and to evaluate changes in model fit. Results The number of siblings was negatively associated with child BMIz [b = -0.18, 95% confidence interval (CI) = -0.35, -0.06, p<0.01, adjusted R2 = 0.16]. There was a negative association between the number of older siblings and child BMIz (b = -0.23, 95% CI = -0.38, -0.11, p<0.01, adjusted R2 = 0.21) as well as between the number of older sisters and child BMIz (b = -0.18, 95% CI = -0.52, -0.09, p<0.01, adjusted R2 = 0.19). However, there were no significant associations between the number of older brothers or the number of younger siblings and child BMIz. Conclusions Based on our findings, sibship composition was found to be associated with BMIz among a sample of preschoolers in KSA. More research is needed to further establish this association and to understand the underlying mechanism of the association of the greater number of older siblings and older sisters with lower BMIz.

Exploring Depression and Nutritional Covariates Amongst US Adults using Shapely Additive Explanations

Background

Depression affects personal and public well-being and identification of natural therapeutics such as nutrition is necessary to help alleviate this public health concern.

Objective

The study aimed to identify feature importance in a machine learning model using solely nutrition covariates.

Methods

A retrospective analysis was conducted using a modern, nationally representative cohort, the National Health and Nutrition Examination Surveys (NHANES 2017-2020). Depressive symptoms were evaluated using the validated 9-item Patient Health Questionnaire (PHQ-9), and all adult patients (total of 7929 individuals) who completed the PHQ-9 and total nutritional intake questionnaire were included in the study. Univariable regression was used to identify significant nutritional covariates to be included in a machine learning model and feature importance was reported. The acquisition and analysis of the data were authorized by the National Center for Health Statistics Ethics Review Board.

Results

7929 patients met the inclusion criteria in this study. The machine learning model had 24 out of a total of 60 features that were found to be significant on univariate analysis (p < 0.01 used). In the XGBoost model the model had an Area Under the Receiver Operator Characteristic Curve (AUROC) = 0.603, Sensitivity = 0.943, Specificity = 0.163. The top four highest ranked features by gain, a measure of the percentage contribution of the covariate to the overall model prediction, were Potassium Intake (Gain = 6.8%), Vitamin E Intake (Gain = 5.7%), Number of Foods and Beverages Reported (Gain = 5.7%), and Vitamin K Intake (Gain 5.6%).

Conclusion

Machine learning models with feature importance can be utilized to identify nutritional covariates for further study in patients with clinical symptoms of depression.

Examining the associations between mothers' motivation to regulate their own eating behaviors, food parenting practices and perceptions of their child's food responsiveness

Based on the Self-Determination Theory, this study examined: 1) how mothers' autonomous and controlled motivation to regulate their own eating behaviors relate to their food parenting practices, and 2) whether and how child food responsiveness (i.e., reactivity and attraction to food) interact with mothers' motivation to predict maternal food parenting practices. Participants were 296 French Canadian mothers of at least one child aged between 2 and 8 years old. Results of partial correlation analyses (controlling for demographics and controlled motivation) showed that maternal autonomous motivation to regulate their own eating behaviors was positively related to autonomy-promoting (i.e., child involvement) and structure-based (i.e., modeling, creating a healthy environment, monitoring) food parenting practices. In contrast, controlling for demographics and autonomous motivation, maternal controlled motivation was positively associated with food-related practices based on coercive control (i.e., the use of food to regulate the child's emotions, the use of food as a reward, pressure to eat, restriction for weight reasons, and restriction for health reasons). Furthermore, the child's food responsiveness was found to interact with mothers' motivation to regulate their own eating behaviors in the prediction of maternal food parenting practices such that mothers with high autonomous motivation or low controlled motivation were found to react with more structure-based (i.e., creating a healthy environment) and autonomy-based (i.e., child involvement) practices, as well as less controlling practices (i.e., the use of food to regulate the child's emotions), to a child who is highly responsive to food. In conclusion, findings suggest that guiding mothers toward developing a more autonomous and less controlled motivation to regulate their own eating behaviors might help them adopt more autonomy-promoting and structure-based and less controlling feeding practices, especially with children who are highly responsive to food.

The association between parents' stress and parental feeding practices and feeding styles: Systematic review and meta-analysis of observational studies

In the extended UNICEF framework of early childhood nutrition, parents' stress is associated with parental feeding style. However, no comprehensive review has examined the association between parents' stress and feeding styles and practices. The objective of our review was to synthesise the current literature examining the association between parents' stress and their feeding practices and/or styles, among parents of children ≤ 5 years old. We searched; MEDLINE, EMBASE, PSYCHINFO and CINAHL from 2019 to 2021. Two investigators independently extracted relevant data and assessed the study quality and the certainty of evidence. Data were pooled using generic inverse variance with fixed effects (<5 comparisons) or random effects (≥5 comparisons) and expressed as correlation coefficients with 95% confidence intervals (CI). Between study heterogeneity was assessed using Cochran's Q and quantified with I² . We identified 6 longitudinal and 11 cross-sectional studies, of which 4 studies provided sufficient data to be pooled. A very small correlation between general stress and restrictive feeding practices was observed (r = 0.06 [95% CI: 0.01-0.12]; no substantial heterogeneity (I²  = 0.00%, P_Q  < 0.85, very low certainty). No correlation between general stress and feeding pressure was identified (r = 0.06 [95% CI: -0.02 to 0.15]). Results showed that both general and parenting stress were associated with suboptimal breastfeeding practices and unresponsive feeding styles. Conclusion: This study demonstrated a low-to-moderate quality of literature for the inclusion of parents' stress in the extended UNICEF care model of child nutrition. Future research needs to explore this relationship longitudinally and in ethnic diverse populations to inform tailored interventions that promote responsive feeding practices.

Clinical strategies for addressing obesity in infants and toddlers

ABSTRACT

Babies' earliest food experiences have a lifelong impact on eating preferences and dietary habits, laying the foundation for obesity risk. NPs have the opportunity to provide education about healthy infant feeding practices before the growth trajectory becomes abnormal and focus intensive education on at-risk families.

Family Eating Behavior and Child Eating Patterns Differences Between Children With and Without Siblings

OBJECTIVE

To examine the differences in family eating behaviors and child eating patterns in children with siblings (nonsingletons) and without siblings (singletons).

METHODS

Cross-sectional analysis of mother-child dyads of 5-7-year-old children, (nonsingletons with a 2-to-4-year-old sibling) was conducted. Anthropometrics were measured. Mothers completed questionnaires and a child dietary log. Healthy Eating Index 2010 (HEI) score was calculated. Linear regression models adjusting for child age, child sex, maternal body mass index, and hours-away-from-home were conducted, with a revised P < .021.

RESULTS

Sixty-eight mother-child dyads (27 singletons, 41 nonsingletons) participated. Singletons exhibited less healthy family eating behaviors (β = -4.98, SE = 1.88, P = .003), and lower total HEI scores than did nonsingletons (average: β = -8.91, SE =2.40, P = .001). On average, singletons had lower scores in 3 HEI components compared with nonsingletons (P < .021 for all).

CONCLUSION

In this sample, singleton children exhibited less healthy eating behaviors. Additional investigation into parent-level differences is warranted.

Association between Sociodemographic Factors and Dietary Patterns in Children Under 24 Months of Age: A Systematic Review

BACKGROUND

Understanding early-life complementary feeding dietary patterns and their determining factors could lead to better ways of improving nutrition in early childhood. The purpose of this review was to evaluate evidence of the association between sociodemographic factors and dietary patterns (DPs) in children under 24 months.

METHODS

Medline (PubMed), Cochrane Central, NICE guidelines, and Trip database were searched for observational studies that evaluated sociodemographic factors and their associations with DP.

RESULTS

Seven studies were selected for the present review. High education level among mothers was inversely associated with unhealthy DPs and positively associated with healthy DPs. Higher household income was negatively associated with unhealthy DPs. Four studies showed a positive association between low household income and unhealthy DPs and three studies showed a positive association between higher household income and healthy DPs. Additionally, in younger mothers, body mass index (BMI ≥ 30.0 kg/m2) and number of children were positively associated with unhealthy DPs.

CONCLUSIONS

This review provides evidence of a positive association between mothers' higher education level, higher household income, higher maternal age, and healthy dietary patterns as well as a negative association between these factors and unhealthy dietary patterns. Further studies from low- and middle-income countries are needed for comparison with associations showed in this review.

Difference in Objectively Measured Physical Activity and Obesity in Children With and Without Siblings

Background/Context: Children without siblings (singletons) have higher rates of obesity than do children with siblings (nonsingletons). Higher moderate to vigorous physical activity (PA) and less sedentary behavior (SB) are associated with lower childhood obesity.

PURPOSE

To examine the difference in PA and SB between singleton and nonsingleton children.

METHODS

Mothers of children ages 5.0-7.9 years old who were singletons or nonsingletons with a sibling between the ages of 2.0 and 4.9 years old were recruited. Height, weight, and waist circumference of the 5.0- to 7.9-year-old children were measured, and age and sex percentiles were calculated. Accelerometry measured SB and PA, including light PA, moderate to vigorous PA, and counts per minute.

RESULTS

Fifty-six mother-child dyads (23 singletons and 33 nonsingletons) with an average child age of 5.7 (0.7) years participated. More singletons were classified as overweight or obese than were nonsingletons (49% vs 17%, P = .04). In adjusted linear models, singletons had less light PA per day (β = -38.1, SE = 19.2, P = .001) and more SB (β = 38.0, SE = 16.5, P = .02) than did nonsingletons, with no difference in moderate to vigorous PA or counts per minute.

CONCLUSION

In this sample, singletons had higher obesity and lower light PA than did nonsingleton children. Investigation into differences in singleton/nonsingleton families, including family health behaviors, may help assess sibling influence in early behavior development.
