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.

The association of early feeding practices with eating behaviors and maternal indulgent feeding behaviors among Saudi preschoolers

Evidence from previous work suggest that feeding practices during the first years of life may influence the development of eating behaviors later in childhood. Early feeding practices may also predict later maternal feeding behaviors. Mothers from an Arab/Middle Eastern background may adopt unique early feeding practices. The objective of this study was to examine the association of offering fruit juice and date syrup-milk mixture in a baby bottle during infancy with: 1) Child eating behaviors during preschool years; 2) Maternal indulgent feeding practices during preschool years. Mothers of preschoolers (n = 115) completed questions adopted from the Children's Eating Behavior Questionnaire (CEBQ), Child Feeding Questionnaire-Arabic (CFQ-A), as well as questions assessing early feeding practices and demographic characteristics. Unadjusted and adjusted logistic regression models were tested to examine the association of early feeding practices with child eating behaviors and maternal indulgent feeding behaviors. Odds ratios (ORs) and respective 95% confidence intervals (CI) were derived. Adjusting for covariates, children who were ever offered fruit juice in a baby bottle as infants were more likely to have high food responsiveness at preschool, compared to children who were not (OR = 2.93, 95% CI = 1.16, 7.42). Mothers who reported ever offering fruit juice in a baby bottle when their children were infants were more likely to adopt greater use of food as a reward when their children were at preschool (OR = 3.25, 95% CI = 1.22, 8.68). Early feeding practices are associated with child eating and maternal feeding behaviors later in childhood. Future longitudinal studies are needed to further establish these associations. Findings from this study can help inform community awareness and education programs to prevent maladaptive feeding practices and promote appropriate feeding strategies throughout childhood.

Arabic translation and validation of a pediatric sleep questionnaire to assess the prevalence of sleep-disordered breathing among Saudi pre-school children

OBJECTIVES

(1) To translate to Arabic a validated pediatric sleep questionnaire, (2) To assess the validity and reliability of the translated questionnaire, and (3) To assess the prevalence of sleep-disordered breathing (SDB) among a group of pre-school children in Jeddah, Saudi Arabia.

METHODS

Using forward and back-translation, a set of 6 hierarchically arranged questions that comprise the Gozal sleep questionnaire was translated into Arabic. Validity was assessed using face validity and content validity for consistency and clarity, using both item-level and scale-level content validity indices (I-CVI, S-CVI). Consent forms were sent to 1783 mothers recruited from 8 different pre-schools in Jeddah between October 2017 and April 2018, and 209 signed and returned the consent forms. Out of this sample, 34 mothers were contacted to assess internal consistency using Cronbach's alpha, and test-retest reliability using Interclass correlation coefficient (ICC). Finally, all 209 mothers were contacted to answer the questionnaire to obtain the prevalence of SDB.

RESULTS

Using face validity and content validity, the translated questionnaire proved to be valid with perfect I-CVI and S-CVI. Internal consistency (Cronbach's Alpha 0.64-0.89) and test-retest reliability (ICC=0.87, p<0.001) showed the translated questionnaire to have good to favorable reliability. Depending on the severity of SDB, the prevalence of SDB was 7.7%, 5.7%, and 3.8% for mild, moderate and severe cut-off values respectively.

CONCLUSION

A validated pediatric sleep questionnaire to assess SDB was translated into Arabic and the translation proved to be valid and reliable. The prevalence of SDB was found to be very comparable to other areas in the world.

Early feeding practices and body mass index z-score among Saudi preschoolers: a cross-sectional study

Background:

Feeding practices during early years may have long-lasting influences on eating behaviors, growth patterns and body mass index (BMI) trajectory. The objectives of this study were to characterize early feeding practices among mothers in Saudi Arabia and examine their associations with child birthweight and BMI z-score (BMIz) at preschool.

Methods:

This is a cross-sectional study including 209 mother-child dyads who were recruited from different preschools around the city of Jeddah, Saudi Arabia. Mothers completed the study questionnaire over the telephone and preschoolers’ anthropometric measurements were objectively measured using standardized procedures. Primary predictors included variables pertaining to breastfeeding initiation, breastfeeding duration, formula milk introduction, complementary feeding, and offering fruit juice, date syrup-milk mixture, and soda drinks in a baby bottle. The study’s primary outcome was BMIz at preschool. Mothers reported child’s birthweight and sociodemographic characteristics. Descriptive statistics were used to characterize early feeding practices. Bivariate analyses and linear regression analysis were used to examine the association of early feeding practices with child birthweight and BMIz at preschool.

Results:

About half of the mothers reported that they have offered fruit juice and/or date syrup-milk mixture in a baby bottle (52.2% and 45.9% respectively), with an average duration of 11.5 months (SD = 7.73) and 5.90 months (SD = 6.13), respectively. Children who were offered fruit juice and/or date syrup-milk mixture in a baby bottle had significantly lower birthweights compared to children who were not (M = 2.79, SD = 0.59 vs. M = 3.06, SD = 0.69, P < 0.01 and M = 2.79, SD = 0.67 vs. M = 3.03, SD = 0.62, P < 0.01, respectively). There was a negative association between introducing fruit juice in a baby bottle and child BMIz at preschool (β: -0.18, 95% confidence interval (CI): -0.83, -0.11); This association was not significant after adjusting for child birthweight and other covariates (β: -0.10, 95% CI: -0.64, 0.09).

Conclusion:

A large proportion of mothers reported offering fruit juice and date syrup-milk mixture in a baby bottle. Additional research is needed to understand associations with child birthweight and BMIz. Longitudinal and interventions studies can help inform counseling guidelines and community campaigns in order to improve early feeding practices in the region.

Oral health-related quality of life in children with celiac disease

PURPOSE

There is limited knowledge about oral health-related quality of life (OHRQoL) in children with celiac disease (CD). This study aimed to assess OHRQoL in children with CD compared to healthy controls.

METHODS

This case-control study included children with CD and healthy controls. Three scales were used to assess OHRQoL in different age groups: 6-7 years, 8-10 years, and 11-14 years. The OHRQoL scores were compared between cases and controls to examine the possible associations between OHRQoL and demographics, socioeconomic status, and oral health.

RESULTS

Overall, 104 children with CD and 104 healthy children (controls) were included. The mean age was 10.67 ± 2.39 years in CD patients and 10.69 ± 2.36 in controls (P = 0.971). Male and female children constituted 50% of each group. Children with CD had significantly higher OHRQoL scores than controls (P = 0.003). Low education levels of parents of children with CD and a higher number of siblings in controls were associated with high OHRQoL scores (P = 0.002, P < 0.020, and P = 0.010, respectively). Recurrent aphthous stomatitis (RAS) increased the OHRQoL scores by 7.5 on average (P = 0.016).

CONCLUSION

Children with CD had poor OHRQoL compared with healthy controls. Poor OHRQoL in children with CD was associated with RAS and with lower parental income and education. RAS was an independent predictor of poor OHRQoL in children with CD.

Changes in Feeding Behavior and Feeding Stress Among Mothers of Preschoolers Before and During the Novel Coronavirus Pandemic

Objective

To examine changes in maternal feeding behaviors (MFB) and maternal feeding stress (MFS) among mothers of preschoolers in Saudi Arabia before and during the novel coronavirus pandemic.

Methods

This is a prospective cohort study including 64 mothers of preschoolers who were drawn from a sample of a 2019 study. Study questionnaire was completed during November–December 2020. MFB were assessed using the Child Feeding Questionnaire-Arabic (CFQ-A) and MFS was assessed using the MFS-mealtimes index and the MFS-maternal resentment/difficult child index. Paired samples t-tests were used to examine changes in MFB and MFS.

Results

Mothers have reported an increase in perceived responsibility (M = 4.09, SD = 0.87 vs. M = 4.33, SD = 0.59, P-value < 0.05) and monitoring (M = 4.23, SD = 0.73 vs. M = 4.48, SD = 0.66, P-value < 0.05) during the pandemic period compared to the period prior to the pandemic. Mothers have reported a decrease in use of food as a reward (M = 4.11, SD = 0.87 vs. M = 2.30, SD = 0.88, P-value < 0.001) and concern about child's diet (M = 3.34, SD = 1.12 vs. M = 2.55, SD = 1.04, P-value <0.001). There was an increase in MFS-maternal resentment/difficult child (M = 2.47, SD = 0.68 vs. M = 2.71, SD = 0.72, P-value < 0.01).

Conclusions

Findings can help inform future research aiming to measure the long-term effects of the pandemic on child outcomes.

The Association between Sibship Composition and Child Eating Behaviors

Development of eating habits and patterns during childhood can have life-long effects on weight and health status. Family structure, functioning, and interactions during mealtimes may influence the development of eating behaviors among children. The objective of this study was to examine the association between sibship composition and child eating behaviors among preschoolers in Saudi Arabia. One hundred and fifteen mothers were recruited through various preschools around the city of Jeddah, Saudi Arabia. A previously validated Arabic version of the Children's Eating Behavior Questionnaire (CEBQ) was completed over the telephone along with questions assessing sibship composition and demographic characteristics. Spearman correlations and adjusted linear regression models were examined to assess the association between sibship composition and child eating behaviors. Adjusting for covariates, number of older siblings was positively associated with emotional over eating, food responsiveness, and the desire to drink. Number of older sisters was positively associated with the desire to drink but negatively associated with food fussiness. Having a greater number of older (rather than younger) siblings may be associated with food-approach eating behaviors. Having a greater number of older sisters may be associated with less food fussiness. Focusing on older siblings in encouraging healthy eating habits and appropriate food choices may be beneficial in promoting adaptive eating behaviors and prevention of excessive energy intake and weight gain. Future longitudinal and mixed-methods research studies with larger sample sizes are needed in order to better understand the underlying mechanisms for the associations between sibship composition and child eating behaviors.

Microbiome-Targeted Therapies as an Adjunct to Traditional Weight Loss Interventions: A Systematic Review and Meta-Analysis

OBJECTIVE

This study evaluated the effect of microbiome-targeted therapies (pre-, pro-, and synbiotics) on weight loss and other anthropometric outcomes when delivered as an adjunct to traditional weight loss interventions in overweight and obese adults.

METHODS

A systematic review of three databases (Medline [PubMed], Embase, and the Cochrane Central Register of Controlled Trials) was performed to identify randomized controlled trials published between January 1, 2010 and December 31, 2020, that evaluated anthropometric outcomes following microbiome-targeted supplements in combination with dietary or dietary and exercise interventions. The pooled mean difference (MD) between treatment and control groups was calculated using a random effects model.

RESULTS

Twenty-one trials with 1233 adult participants (76.4% female) with overweight or obesity were included. Separate meta-analyses were conducted for probiotics (n=11 trials) and synbiotics (n=10 trials) on each anthropometric outcome; prebiotics were excluded as only a single study was found. Patient characteristics and methodologies varied widely between studies. All studies incorporated some degree of caloric restriction, while only six studies included recommendations for adjunct exercise. Compared with dietary or dietary and exercise interventions only, probiotics resulted in reductions in body weight (MD: -0.73 kg; 95% confidence interval [CI]: -1.02 to -0.44, p < 0.001), fat mass (MD: -0.61 kg; 95% CI: -0.77 to -0.45; p<0.001) and waist circumference (MD: -0.53 cm; 95% CI: -0.99 to -0.07, p=0.024) while synbiotics resulted in reductions in fat mass (MD: -1.53 kg; 95% CI: -2.95 to -0.12, p=0.034) and waist circumference (MD: -1.31 cm; 95% CI: -2.05 to -0.57, p<0.001).

CONCLUSION

This analysis indicates that microbiome-targeted supplements may enhance weight loss and other obesity outcomes in adults when delivered as an adjunct to dietary or dietary and exercise interventions. Personalized therapy to include microbiome-targeted supplements may help to optimize weight loss in overweight and obese individuals.

Maternal feeding stress during mealtimes as a mediator between child food fussiness and maladaptive feeding behaviors among mothers of preschoolers

Parenting stress has been linked to maladaptive feeding behaviors and adverse child outcomes. Maternal stress that is specific to child feeding during mealtimes has not been previously explored. We sought to examine our hypothesis that maternal feeding stress during mealtimes (MFS-mealtimes) mediates the association of child food fussiness and concern about child's diet with maladaptive feeding behaviors. Mothers (n = 100) were recruited through different preschoolers around the city of Jeddah, Saudi Arabia. Participants completed an online questionnaire, which included a newly developed MFS-mealtimes index (Cronbach's α = 0.89), the Child Feeding Questionnaire- Arabic (CFQ-A), and the child food fussiness scale. We conducted path analysis to test our hypothesis, and we used bivariate analyses to inform our path model. Mean child age was 4.76 years (SD = 0.62), and 62% of children were female. Mean maternal age was 33.9 years (SD = 5.83). Results from path analysis showed that concern about child's diet and child food fussiness were each associated with higher MFS-mealtimes (B = 0.11, 95% confidence interval (CI) = 0.01, 0.20, p < 0.05, and B = 0.29, 95% CI = 0.05, 0.53, p < 0.01, respectively). MFS-mealtimes was in turn associated with higher pressure to eat (B = 0.45, 95% CI = 0.18, 0.71, p < 0.05). Goodness of fit indices showed good model fit (p > X² = 0.83, SRMR = 0.005, and CFI = 1.00). Our findings suggest a novel approach for promoting a favorable mealtime environment. Parenting stress reduction interventions have been shown to be successful in reducing stress levels and may be utilized for minimizing feeding stress during mealtimes. Mothers of picky eaters may be specifically targeted for intervention programs. Long term consequences of excessive MFS-mealtimes, as well as variations between cultures need further evaluation.

Dental maturity in children with celiac disease: a case-control study

Background

Celiac disease (CD) is an immune-related enteropathy triggered by gluten ingestion in susceptible individuals. Oral manifestations of CD have been frequently described, although reports on dental maturity (DM) are scant. Thus, the aim of this study is to assess the prevalence of DM in CD patients and to test for possible predictors.

Methods

This is a case–control study of children with CD and healthy controls between 2017 and 2020. A panoramic radiograph and comprehensive oral examination were performed for each participant. Dental age (DA) was measured according to Demirjian’s method and DM was calculated by subtracting the chronological age (CA) from the DA. Statistical analysis was performed to compare the DM between CD patients and controls, and a multivariate analysis was utilized to look for predictors of DM.

Results

Two-hundred and eight participants (104 children with CD, and 104 healthy controls) were incorporated. The mean age for CD patients was 10.67 ± 2.40 years, and 10.69 ± 2.37 years for healthy controls (P = 0.971). CD patients had a higher prevalence of delayed DM than controls (62.5% vs. 3%, respectively). They also had a greater delay in DM than controls (− 7.94 ± 10.94 vs. 6.99 ± 8.77, P < 0.001). A multivariate analysis identified age between 6 and 7 years (β ± SE = 16.21 ± 2.58, P < 0.001), as the only predictor for DM.

Conclusions

CD patients had a greater prevalence of delayed DM than controls. No predictors for DM could be found, except young age.

Understanding the Interrelationship between Education, Income, and Obesity among Adults in Saudi Arabia

OBJECTIVE

To examine the association of sociodemographic variables with the odds of being obese among adults in Saudi Arabia, and to examine whether or not the association between the educational level and the odds of being obese among adults in Saudi Arabia is modified by the income level.

METHODS

A total of 3,925 participants were recruited for this cross--sectional study. Sociodemographic and anthropometric data were collected using standardized procedures. Unadjusted and adjusted logistic regression models were examined, with a dichotomous obesity status variable as the outcome. Furthermore, an interaction term for income level with educational level was tested and appeared significant. Thus, additional regression models were run in order to examine the association between educational level and obesity status separately among the low- and higher-income groups.

RESULTS

Compared to participants with a college degree or higher, illiterate participants and those with an elementary education had higher odds of obesity (OR: 2.76, 95% CI: 1.81-4.22, and OR: 2.68, 95% CI: 1.89-3.82, respectively). However, participants with a low income had lower odds than participants who had a higher income (OR: 0.84, 95% CI: 0.70-0.99). Examining the association between educational level and obesity while stratifying by income revealed that a negative association between education and obesity exists among both income groups. However, the magnitude of the ORs was higher among participants with higher income, suggesting a stronger association between education and obesity among wealthier individuals.

CONCLUSION

Individuals in the highest income bracket with lower levels of education may have greater odds of obesity. Targeting them in intervention programs is warranted.

Evaluation of growth chart use among clinicians in Saudi Arabia: Is there a need for change?

Objective

To identify types of growth charts and practices employed by clinicians to assess pediatric patients in Saudi Arabia; To assess clinicians' interpretation and comprehension of growth charts.

Methods

This is a Cross-sectional study including 105 pediatricians and dietitians residing in Saudi Arabia. Participants completed an online questionnaire which assessed: region of residence, work facility, typical practices in pediatric patient assessment, and ability to correctly interpret and comprehend growth chart data. Data were analyzed using descriptive and chi-square statistics.

Results

Majority of respondents (70.5%) reported typically using either the CDC or WHO growth charts. Only 52.4% reported always using growth charts and discussing weight status of pediatric patients during annual/regular visits, and 54.3% reported discussing the patient's weight status with his/her caregiver(s) under all circumstances. Only 23.8% correctly answered the interpretation question, while 50.5% correctly answered the comprehension question. A higher percentage of clinicians residing in the Southern, Central, and Western regions reported that they always or often discuss the patient's weight status with his/her caregiver(s) (100%, 89.2% and 81.4%, respectively) (P value = 0.004). Clinicians who worked in private hospitals only, and who typically used the Saudi growth charts were least likely to report that they always or often discuss the patient's weight status with his/her caregiver(s) (50% and 61.5%, respectively) (All Ps < .05).

Conclusion

Growth chart utilization among clinicians in Saudi Arabia needs further evaluation. Clinicians residing in the Northern and Eastern regions, who worked in private hospitals only, and who typically used the Saudi growth charts showed poorer practices with regards to growth chart utilization.

Obesity and morbid obesity associated with higher odds of hypoalbuminemia in adults without liver disease or renal failure

BACKGROUND AND OBJECTIVE

Studies are needed in order to inform recommendations for interpreting albumin levels among obese individuals without known medical conditions associated with hypoalbuminemia. The objective of this study was to examine the association of obese and morbidly obese status with hypoalbuminemia, while adjusting for age, sex, diabetes, prediabetes, diabetic nephropathy, and nephrotic syndrome.

PATIENTS AND METHODS

Retrospective data collection from adult patients presenting to the outpatient Endocrinology and Metabolism Clinic was performed between January 2015 and December 2015. An initial sample of 180 patients was selected. After excluding patients who were younger than 18 years, who had known cases of liver disease or renal failure, or who had missing data, a final sample of 122 subjects was identified. Serum albumin and objectively measured weight and height data were retrieved from hospital records. A board-certified endocrinologist reviewed patient records to identify the presence of renal and diabetic conditions. Descriptive statistics were used to examine sample characteristics. Multiple logistic regression analysis was used to examine the association of obesity and morbid obesity with hypoalbuminemia (serum albumin < 34 g/L) while adjusting for age, sex, diabetes, prediabetes, diabetic nephropathy, and nephrotic syndrome.

RESULTS

Approximately 43% of the sample were categorized as obese and 13% were categorized as morbidly obese. The mean serum albumin level was 38.00 g/L (standard deviation [SD] = 4.26) among subjects who were neither overweight nor obese, 38.35 g/L (SD = 0.48) among overweight subjects, 34.57 g/L (SD = 4.71) among obese subjects, and 33.81 g/L (SD = 3.71) among morbidly obese subjects. Adjusting for age, sex, diabetes, prediabetes, nephrotic syndrome, and diabetic nephropathy, obese subjects had significantly higher odds of hypoalbuminemia (odds ratio [OR]: 4.10, 95% confidence interval [CI]: 1.50-11.27, P-value = 0.006), as did morbidly obese subjects (OR: 6.94, 95% CI: 1.91-25.23, P-value = 0.003).

CONCLUSION

The findings suggest that obesity and morbid obesity can be considered as independent predictors of hypoalbuminemia. The findings can be used to inform future studies aiming to better understand the association of obesity and morbid obesity with hypoalbuminemia and to help inform guidelines for clinicians on how to correctly interpret and utilize serum albumin data for obese individuals.

Effect of Sibling Birth on BMI Trajectory in the First 6 Years of Life

BACKGROUND AND OBJECTIVE

This study examined the longitudinal association between birth of a sibling and changes in body mass index z-score (BMIz) trajectory during the first 6 years of life.

METHODS

Children (n = 697) were recruited across 10 sites in the United States at the time of birth. Sibship composition was assessed every 3 months. Anthropometry was completed when the child was age 15 months, 24 months, 36 months, 54 months, and in first grade. Children were classified based on the timing of their sibling's birth. A piecewise quadratic regression model adjusted for potential confounders examined the association of the birth of a sibling with subsequent BMIz trajectory.

RESULTS

Children whose sibling was born when they were 24 to 36 months or 36 to 54 months old, compared with children who did not experience the birth of a sibling by first grade, had a lower subsequent BMIz trajectory and a significantly lower BMIz at first grade (0.27 vs 0.51, P value = 0.04 and 0.26 vs 0.51, P value = 0.03, respectively). Children who did not experience the birth of a sibling by the time they were in first grade had 2.94 greater odds of obesity (P value = 0.046) at first grade compared with children who experienced the birth of a sibling when they were between 36 to 54 months old.

CONCLUSIONS

A birth of a sibling when the child is 24 to 54 months old is associated with a healthier BMIz trajectory. Identifying the underlying mechanism of association can help inform intervention programs.

Maternal behavior as a predictor of sibling interactions during mealtimes

Children who frequently experience encouragement or pressure to eat are more likely to exhibit less favorable eating behaviors and dietary outcomes. Siblings can encourage or pressure each other to eat during mealtimes, but the role of mothers in shaping sibling mealtime interactions is not understood. The objective of this study was to examine the association between the behavior of mothers and siblings during mealtimes. The associations of maternal presence and maternal engagement with children during mealtimes with encouragements to eat delivered by the child to his/her sibling were examined. Children aged 4-8years (n=73) were videotaped while eating a routine evening meal at home with one sibling present. Encouragement to eat delivered by the index child to the sibling, maternal presence, and non-food-related and food-related maternal engagement were coded from the videotapes. Poisson regression showed that maternal presence was associated with fewer encouragements to eat from the index child to the sibling (rate ratio (RR): 0.40, 95% confidence interval (CI): 0.26, 0.62). Each type of maternal engagement was independently associated with the number of encouragements to eat from the index child to the sibling: maternal engagement that was not food-related was associated with fewer encouragements to eat (RR: 0.62, 95% CI: 0.53, 0.73), while maternal engagement that was food-related was associated with more encouragements to eat (RR: 1.49, 95% CI: 1.22, 1.81). Future studies may explore how sibling interactions may mediate links between maternal behavior during mealtimes and children's health-related outcomes.

Sibling feeding behavior: Mothers as role models during mealtimes

Siblings may act as caregivers and role models during mealtimes, and develop caregiving skills by observing and imitating the behavior of their mothers. The objective of this study was to examine the association between maternal feeding behaviors and encouragements to eat delivered from the sibling to the index child during mealtimes. Index children aged 4-8 years (n = 69) were videotaped while eating a routine evening meal at home with one sibling present. Encouragements to eat delivered from the sibling to the index child were coded from the videotapes. Mothers completed the Child Feeding Questionnaire and the Caregiver's Feeding Styles Questionnaire. Poisson regression was used to examine the association of maternal Pressure to Eat, Restriction, Monitoring, Verbal Direction, and Coercion with number of encouragements to eat delivered from the sibling to the index child. Models were adjusted for index child's age, sex, and race/ethnicity, and maternal education. Results showed that maternal Pressure to Eat (Rate Ratio (RR): 1.39, 95% confidence interval (CI): 1.19, 1.69), Restriction (RR: 1.31, 95% CI: 1.07, 1.60), Verbal Direction (RR: 2.04, 95% CI: 1.68, 2.47), and Coercion (RR: 1.58, 95% CI: 1.29, 1.92) were each positively associated with the number of encouragements to eat delivered from the sibling to the index child. Maternal Monitoring was not associated with the number of encouragements to eat delivered from the sibling to the index child (RR: 0.92, 97% CI: 0.78, 1.09). Findings suggest that maternal behavior during mealtimes may affect the index child indirectly by shaping the behavior of siblings. Since controlling feeding behaviors have been associated with greater child obesity risk, future studies may evaluate the compounded effect of experiencing controlling feeding behaviors from both mothers and siblings.

Higher weight status of only and last-born children. Maternal feeding and child eating behaviors as underlying processes among 4-8 year olds

Birth order has been associated with childhood obesity. The objective of this cross-sectional study was to examine maternal feeding and child eating behaviors as underlying processes for increased weight status of only children and youngest siblings. Participants included 274 low-income 4-8 year old children and their mothers. The dyads completed a videotaped laboratory mealtime observation. Mothers completed the Caregiver's Feeding Styles Questionnaire and the Children's Eating Behavior Questionnaire. Child weight and height were measured using standardized procedures. Path analysis was used to examine associations of birth order, maternal feeding behavior, child eating behavior, and child overweight/obese status. The association between only child status and greater likelihood of overweight/obesity was fully mediated by higher maternal Verbal Discouragement to eat and lower maternal Praise (all p values < 0.05). The association between youngest sibling status and greater likelihood of overweight/obesity was partially mediated by lower maternal Praise and lower child Food Fussiness (all p values < 0.05). Results provide support for our hypothesis that maternal control and support and child food acceptance are underlying pathways for the association between birth order and weight status. Future findings can help inform family-based programs by guiding family counseling and tailoring of recommendations for family mealtime interactions.

Mealtime behavior among siblings and body mass index of 4-8 year olds: a videotaped observational study

Background

Being a last-born child and having a sister have been associated with higher body mass index (BMI). Encouragement to eat that overrides children’s self-regulation has been reported to increase the risk of obesogenic eating behaviors. This study sought to test the hypothesis that encouragement to eat during mealtime from older siblings and sisters mediates associations of being last-born or having a sister with higher BMI.

Methods

Children aged 4–8 years (n = 75) were videotaped while eating a routine evening meal at home with one sibling present. Encouragement to eat (defined as direct prompts to eat or general positive statements about food) delivered to the index child (IC) from the sibling was coded from the videotape. Path analysis was used to examine associations between IC’s birth order, sibling’s sex, encouragement counts, and IC’s measured BMI z-score (BMIz).

Results

Being the younger sibling in the sibling dyad was associated with the IC receiving more encouragements to eat from the sibling (β: 0.93, 95 % confidence interval (CI): 0.59, 1.26, p < 0.0001). The IC having a sister compared with a brother was not associated with the IC receiving more encouragements to eat from the sibling (β: 0.18, 95 % CI: −0.09, 0.47, p = 0.20). The IC receiving more encouragements to eat from the sibling was associated with lower IC BMIz (β: −0.06, 95 % CI: −0.12, 0.00, p = 0.05).

Conclusions

Children were more likely to receive encouragements to eat from older siblings than younger siblings. Being the recipient of encouragements to eat from a sibling was associated with lower, not higher, child BMIz, which may reflect sibling modeling of maternal behavior. Future longitudinal studies are needed to examine whether encouragements to eat from siblings lead to increase in BMI over time. Encouragements from siblings may be a novel intervention target for obesity prevention.
