The explanatory role of maternal feeding practices: do they explain ethnic differences in body weight of preadolescents?

The influence of family characteristics on food parenting practices among parents with school-age children and adolescents: A systematic review

Family characteristics can influence parents' implementation of food parenting practices. However, with a growing body of research on family characteristics and food parenting practices, a systematic review of the related topic has yet to be found in the current literature. Hence, the study aimed to review existing studies on family characteristics and food parenting practices among parents with school-age children and adolescents. Family characteristics refer to the family background or demographics that involve race/ethnicity, family income, parents' education levels, food security, culture, acculturation, and family structure. The study used Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for the review process. The data was collected from EBSCOhost Discovery, PubMed, and Scopus databases. Forty-five relevant articles were analyzed and summarized, and the findings were presented in three themes, including (1) culture, races/ethnicities, and acculturation, (2) socioeconomic status and food security, and (3) family structure. The results showed that the family characteristics identified in this study can influence the engagement of food parenting practices among parents with school-age children and adolescents. Several issues have been addressed for the advancement of future research, which can lead to better suggestions and implementation of food parenting practices among parents. Therefore, parents can improve their food parenting experiences and enhance their children's health, growth, and development.

Child eating behavior predicts body mass index after 1 year: results from the Swiss Preschooler's Health Study (SPLASHY)

Child obesity is a growing global issue. Preventing early development of overweight and obesity requires identifying reliable risk factors for high body mass index (BMI) in children. Child eating behavior might be an important and malleable risk factor that can be reliably assessed with the parent-report Child Eating Behavior Questionnaire (CEBQ). Using a hierarchical dataset (children nested within child care centers) from a representative cohort of Swiss preschool children, we tested whether eating behavior, assessed with a 7-factor solution of the CEBQ, and BMI at baseline predicted the outcome BMI after 1 year, controlling for socioeconomic status (n = 555; 47% female; mean age = 3.9 years, range: 2.2-6.6; mean BMI = 16 kg/m2, range: 11.2-23; mean age- and sex-corrected z-transformed BMI, zBMI = 0.4, range -4 to +4.7). The statistical model explained 65.2% of zBMI at follow-up. Baseline zBMI was a strong positive predictor, uniquely explaining 48.8% of outcome variance. A linear combination of all CEBQ scales, taken together, explained 10.7% of outcome variance. Due to their intercorrelations, uniquely explained variance by any individual scale was of negligible clinical relevance. Only food responsiveness was a significant predictor, when accounting for all other predictors and covariates in the model, and uniquely explained only 0.4% of outcome variance. Altogether, our results confirm, extend, and refine previous research on eating behavior and zBMI in preschool children, by adjusting for covariates, accounting for intercorrelations between predictors, partitioning explained outcome variance, and providing standardized beta estimates. Our findings show the importance of carefully examining the contribution of predictors in multiple regression models for clinically relevant outcomes.

Associations between parental and pre-adolescents' physical activity and diet quality: The role of parental child care involvement and child's sex

BACKGROUND

Research has demonstrated the importance of the family environment in the eating and activity levels of offspring. We examined the cross-sectional associations between moderate-to-vigorous physical activity (MVPA) and diet quality of parents and the MVPA and diet quality of pre-adolescents. Interactions were tested to assess whether the child's sex and the parental level of involvement in daily child care moderated these associations.

METHODS

Data from 2467 pre-adolescents (age 11.5 ± 0.2 years; collected in 2015-2016) and their parents or caregivers from a large-scale prospective birth cohort study in Amsterdam (ABCD-study) was used. Parents and pre-adolescents individually reported their diet quality and physical activity. Child care involvement was assessed using the Caregiver Child Interaction Scale. With hierarchical linear regression analyses, we assessed the independent contribution of fathers and mothers.

RESULTS

An association between mother-child MVPA was found (β = 0.013; 95 % CI: 0.006;0.021). The association between father-child MVPA was only significant for highly involved fathers (β = 0.014; 95 % CI: 0.004;0.023). The child's sex did not change these MVPA associations. Regarding diet quality, associations were found between mother-child diet quality score (DQS) (β = 0.254; 95 % CI: 0.192;0.316) and father-child DQS, with stronger associations between fathers and sons (β = 0.234; 95 % CI: 0.169;0.298) than between fathers and daughters (β = 0.114; 95 % CI: 0.047;0.181). Parental levels of involvement did not change these associations.

CONCLUSION

These findings demonstrate that both parental behaviours represent an important factor in physical activity and diet quality in pre-adolescents in a sex-specific manner. As such, it is essential to include both parents in research to obtain the necessary insights for developing effective interventions to promote children's healthy eating and physical activity behaviours.

Associations Between Maternal Lipid Blood Levels at the 13th Week of Pregnancy and Offspring's Adiposity at Age 11-12 Years

CONTEXT

There is increasing evidence that intrauterine lipid metabolism influences the adiposity of the newborn and the first years thereafter. It remains unclear if these effects persist when these children grow older.

OBJECTIVE

This study examined the associations between maternal lipid blood levels during the 13th week of pregnancy and an offspring's adiposity, measured at age 11-12, and if these associations were moderated by the child's sex.

METHODS

Data were obtained from a community-based birth cohort, the Amsterdam Born Children and their Development (ABCD) study. At a median of 13 weeks' gestation, nonfasting blood samples of triglycerides (TGs), total cholesterol (TC), free fatty acids (FFAs), and apolipoprotein B/apolipoprotein A1 ratio (ApoB/ApoA1) were measured. An offspring's body mass index (BMI), subcutaneous fat (SCF), waist-to-height-ratio (WHtR), and fat percentage (fat%) were measured at age 11-12. Mothers with at-term born children were included (n = 1853). Multivariable linear regression analyses were performed to assess the associations between maternal lipids and each offspring's adiposity outcome separately. Sex differences were additionally evaluated.

RESULTS

TGs, TC, ApoB/ApoA1, and FFAs were significantly positively associated with BMI, WHtR, and fat% (adjusted for gestational age at blood sampling, child's age, sex, and sexual maturation). After additional adjustments for potential confounders and covariates, only TGs remained significantly associated with WHtR (0.45, 95% CI -0.007; 0.91). There were no associations between maternal lipids and SCF and no clear sex-specific results were found.

CONCLUSION

Overall, our results do not strongly support that maternal lipid profile during the 13th week of pregnancy has programming effects on adiposity in preadolescence.
