General and food-specific parenting: measures and interplay

BACKGROUND: Parental influence on child food intake is typically conceptualized at three levels—parenting practices, feeding style, and parenting style. General parenting style is modeled at the most distal level of influence and food parenting practices are conceptualized as the most proximal level of influence. The goal of this article is to provide insights into contents and explanatory value of instruments that have been applied to assess food parenting practices, feeding style, and parenting style. METHODS: Measures of food parenting practices, feeding style, and parenting style were reviewed, compared, and contrasted with regard to contents, explanatory value, and interrelationships. RESULTS: Measures that are used in the field often fail to cover the full scope and complexity of food parenting. Healthy parenting dimensions have generally been found to be positively associated with child food intake (i.e., healthier dietary intake and less intake of energy-dense food products and sugar-sweetened beverages), but effect sizes are low. Evidence for the operation of higher-order moderation has been found, in which the impact of proximal parental influences is moderated by more distal levels of parenting. CONCLUSIONS: Operationalizing parenting at different levels, while applying a contextual higher-order moderation approach, is advocated to have surplus value in understanding the complex process of parent–child interactions in the area of food intake. A research paradigm is presented that may guide future work regarding the conceptualization and modeling of parental influences on child dietary behavior

The effect of time delay in plant-pathogen interactions with host demography

Background: There is a need for valid and comprehensive measures of parental influence on children's energy balance-related behaviours (EBRB). Such measures should be based on a theoretical framework, acknowledging the dynamic and complex nature of interactions occurring within a family. The aim of the Family & Dietary habits (F&D) project was to develop a conceptual framework identifying important and changeable family processes influencing dietary behaviours of 13-15 year olds. A second aim was to develop valid and reliable questionnaires for adolescents and their parents (both mothers and fathers) measuring these processes. Methods: A stepwise approach was used; (1) preparation of scope and structure, (2) development of the F&D questionnaires, (3) the conducting of pilot studies and (4) the conducting of validation studies (assessing internal reliability, test-retest reliability and confirmatory factor analysis) using data from a cross-sectional study. Results: The conceptual framework includes psychosocial concepts such as family functioning, cohesion, conflicts, communication, work-family stress, parental practices and parental style. The physical characteristics of the home environment include accessibility and availability of different food items, while family meals are the sociocultural setting included. Individual characteristics measured are dietary intake (vegetables and sugar-sweetened beverages) and adolescents' impulsivity. The F&D questionnaires developed were tested in a test-retest (54 adolescents and 44 of their parents) and in a cross-sectional survey including 440 adolescents (13-15 year olds), 242 mothers and 155 fathers. The samples appear to be relatively representative for Norwegian adolescents and parents. For adolescents, mothers and fathers, the test-retest reliability of the dietary intake, frequencies of (family) meals, work-family stress and communication variables was satisfactory (ICC: 0.53-0.99). Barratt Impulsiveness Scale-Brief (BIS-Brief) was included, assessing adolescent's impulsivity. The internal reliability (Cronbach's alphas: 0.77/0.82) and test-retest reliability values (ICC: 0.74/0.77) of BIS-Brief were good. Conclusions: The conceptual framework developed may be a useful tool in guiding measurement and assessment of the home food environment and family processes related to adolescents' dietary habits, in particular and for EBRBs more generally. The results support the use of the F&D questionnaires as psychometrically sound tools to assess family characteristics and adolescent's impulsivity

Measuring child temperament: Validation of a 3-item Temperament Measure and 13-item Impulsivity Scale

A 3-item Temperament Measure and a 13-item Impulsivity Scale were tested against the 36-item Children's Behaviour Questionnaire (CBQ). Overall, 229 caregivers completed the CBQ and the 3-item Temperament Measure based on the traits of Surgency, Negative Affectivity and Effortful Control as measured by the CBQ. Their children completed the Impulsivity Scale. Psychometrics of the CBQ and the Impulsivity Scale were examined, which were considered good in terms of internal consistency and factorial structure. The three temperament items correlated with the average scores on the corresponding CBQ factors. Furthermore, Surgency was highly related to Impulsivity. Findings provide evidence for the applicability of the Impulsivity and Temperament Measures for research

Moderators of the Relationship Between Physical Activity Enjoyment and Physical Activity in Children

BACKGROUND: Physical activity (PA) enjoyment may be an important determinant of long-term habitual, self-sustained PA behavior in children. The objective of the current study was to contribute toward a better understanding of how children's PA enjoyment is associated with PA behavior by examining the influence of age, gender, BMI, and impulsivity as theoretically hypothesized moderators of this relationship. METHODS: PA was measured in 171 children (77 boys, 91 girls) using accelerometers, and PA enjoyment was assessed with the validated Physical Activity Enjoyment Scale in 9-year-old children from the KOALA Birth Cohort Study, the Netherlands. Linear regressions were fitted. Moderation was tested by adding interaction terms between PA enjoyment and the potential moderators. RESULTS: We found a significant 3-way interaction (PA enjoyment x gender x impulsivity) for all intensities of PA behavior. In boys, impulsivity strengthened the relationship between PA enjoyment and PA behavior, whereas in girls impulsivity weakened this relationship. CONCLUSION: In girls, this may be explained by the relative automatic occurrence of PA behavior in impulsive girls (independent of PA enjoyment). In boys, the possibility that impulsivity is associated with hyperactivity may explain this moderation. The current study may encourage researchers to investigate these interactions in future studies

General parenting styles and children's obesity risk: Changing focus

Contains fulltext : 197324.pdf (publisher's version ) (Open Access)Increasing attention has been given to direct associations of general parenting styles with children's obesity. General parenting styles (i.e., authoritarian, authoritative, permissive, and uninvolved) refer to the broad emotional context reflecting childrearing across situations and domains (Darling and Steinberg, 1993). Parenting styles focus less on what parents do (i.e., behavior-specific parenting practices) and more on how they do it in general (Power, 2013). In this commentary, we argue that general parenting styles should be conceptualized as a contextual factor that may moderate the influence of weight-related (e.g., food) parenting practices on behavior and weight outcomes among children, as opposed to having direct effects on those outcomes.4 p

Longitudinal association of neighborhood variables with Body Mass Index in Dutch school-age children: The KOALA Birth Cohort Study

Changes in the neighborhood environment may explain part of the rapid increase in childhood overweight and obesity during the last decades. To date few theory-driven rather than data-driven studies have explored longitudinal associations between multiple neighborhood characteristics and child body weight development. We aimed to assess the relationship between physical, social and perceived safety related characteristics of the neighborhood and Body Mass Index (BMI) development in children during early school age, using a longitudinal design. We included an examination of moderating and confounding factors based on a conceptual model adapted from the EnRG framework (Environmental Research framework for weight Gain prevention) and empirical research. Analyses included 1887 children from the KOALA Birth Cohort Study followed from baseline age 4-5 years until 8-9 years. For children age 4-5 years, parents completed a questionnaire measuring characteristics of the neighborhood. Reliability and factor analyses were used to identify constructs for neighborhood characteristics. Linear regression analysis was performed to assess the relationship between neighborhood constructs and BMI z-scores cross-sectionally at age 4-5 years and longitudinally using Generalized Estimating Equations with BMI z-scores over 5 repeated measurements until age 8-9 years. Fourteen constructs were identified and grouped in three domains including perceived physical, social, or safety related characteristics of the neighborhood. Cross-sectionally, a lower BMI z-score was associated with higher perceived physical attractiveness of the neighborhood environment (standardized regression coefficient (β)-0.078, 95% CI-0.123 to-0.034) and a higher level of social capital (β-0.142,-0.264 to-0.019). Longitudinally, similar associations were observed with potentially even stronger regression coefficients. This study suggests that BMI in children is mainly related to the modifiable physical and social environment of the conceptual model and not related to safety as perceived by parents. © 2015 Elsevier Ltd
