BackgroundLittle is known about how factors within the general family environment are associated with weight and related behaviors among adolescents/young adults.MethodsWe studied 3768 females and 2614 males, 14–24 years old in 2011, participating in the Growing Up Today Study 2. We used generalized mixed models to examine cross-sectional associations of family functioning and quality of mother- and father-adolescent relationship with adolescent/young adult weight status, disordered eating, intake of fast food and sugar-sweetened beverages, screen time, physical activity, and sleep duration. In all models, we included participant’s age and family structure.ResultsEighty percent of participants reported high family functioning and 60 % and 50 % of participants reported high-quality mother and father relationship, respectively. Among both males and females, high family functioning was associated with lower odds of disordered eating (adjusted odds ratio [AOR] females = 0.53; 95 % Confidence Interval [CI] = 0.45–0.63; AOR males = 0.48; CI = 0.39–0.60), insufficient physical activity, i.e., less than 1 h/day, (AOR females = 0.74; CI = 0.61–0.89; AOR males = 0.73; CI = 0.58–0.92), and insufficient sleep, i.e., less than 7 h/day, (AOR females = 0.56; CI = 0.45–0.68; AOR males = 0.65; CI 0.5–0.85). High family functioning was also associated with lower odds of being overweight/obese (AOR = 0.73; CI = 0.60–0.88) and eating fast food one or more times/week (AOR = 0.74; CI = 0.61–0.89) among females only. Among females, high-quality mother and father relationship were both associated with lower odds of being overweight/obese and disordered eating, eating fast food, and insufficient sleep and the magnitude of associations were similar for mother and father relationship quality (AOR range 0.61–0.84). Among males, high-quality mother and father relationship were both associated with lower odds of disordered eating, insufficient physical activity and insufficient sleep, but only father relationship quality was associated with lower odds of overweight/obesity.ConclusionsAdolescents/young adults reporting high family functioning and more positive relationships with their parents reported better weight-related behaviors. For weight status, females appear to be affected equally by the quality of their relationship with both parents, whereas males may be more affected by their relationship with fathers.

BackgroundEstimates of picky eating are quite high among young children, with 14-50% of parents identifying their preschoolers as picky eaters. Dietary intake and preferences during the preschool years are characterized by slowing growth rates and children developing a sense of autonomy over their feeding and food selection. We argue that the current conceptualization of picky eating defines acts of resistance or expressions of preference (acts of autonomy) by a child as deviant behaviour. This conceptualization has guided research that uses a unidirectional, parent to child approach to understanding parent-child feeding interactions.ObjectivesBy reviewing the current feeding literature and drawing parallels from the rich body of child socialization literature, we argue that there is a need to both re-examine the concept and parent/clinician perspectives on picky eating. Thus, the objective of this paper is two-fold: 1) We argue for a reconceptualization of picky eating whereby child agency is considered in terms of eating preferences rather than categorized as compliant or non-compliant behaviour, and 2) We advocate the use of bi-directional relational models of causality and appropriate methodology to understanding the parent-child feeding relationship.DiscussionResearchers are often interested in understanding how members in the parent-child dyad affect one another. Although many tend to focus on the parent to child direction of these associations, findings from child socialization research suggest that influence is bidirectional and non-linear such that parents influence the actions and cognitions of children and children influence the actions and cognitions of parents. Bi-directional models of causality are needed to correctly understand parent-child feeding interactions.ConclusionsA reconceptualization of picky eating may elucidate the influence that parental feeding practices and child eating habits have on each other. This may allow health professionals to more effectively support parents in developing healthy eating habits among children, reducing both stress around mealtimes and concerns of picky eating.

BackgroundParents influence their children’s obesity risk through feeding behaviours and modeling of weight-related behaviours. Little is known about how the general home environment, including parental stress, may influence children’s weight. The objective of this study was to explore the association between parenting stress and child body mass index (BMI) as well as obesity risk factors, physical activity and television (TV) viewing.MethodsWe used cross-sectional data from 110 parent–child dyads participating in a community-based parenting intervention. Child heights and weights were measured by trained research assistants. Parents (93% mothers) reported level of parenting stress via the Parenting Stress Index- Short Form (PSI-3-SF) as well as children’s activity behaviours and TV viewing. This was an ethnically diverse (55% Hispanic/Latino, 22% Black), low-income (64% earning < $45,000/year) sample.ResultsLevel of parenting stress was not associated with children’s risk of being overweight/obese. Children with highly stressed parents were less likely to meet physical activity guidelines on weekdays than children with normally stressed parents (OR = 0.33, 95% CI, 0.12-0.95). Parents experiencing high stress were less likely to set limits on the amount of TV their children watched (OR = 0.32, 95% CI, 0.11, 0.93).ConclusionResults suggest stress specific to parenting may not be associated with increased obesity risk among children. However, future interventions may need to address stress as a possible underlying factor associated with unhealthful behaviours among preschoolers.

OBJECTIVE: To test the feasibility, acceptability and preliminary impact of Parents and Tots Together (PTT), a family-based obesity prevention intervention, in Canada.PARTICIPANTS: Canadian parents of preschoolers (aged 2-5 years).SETTING: Ontario Early Years centres in southwestern Ontario. INTERVENTION:A pilot randomized controlled trial involving 48 parents who received either the PTT intervention (n = 27) or an attention-matched control home safety intervention (n = 21). To evaluate the feasibility of PTT, we assessed participant retention and outcome evaluation completion rates. To evaluate acceptability, we assessed program attendance and parents' responses to program satisfaction surveys. To evaluate preliminary impact, we assessed children's body mass index (BMI) at baseline, after intervention (end of 9-week intervention) and at 9-month follow-up. As well, at each time point, parents completed surveys assessing stress and self-efficacy related to parenting, children's sleep, activity, TV viewing and diet. OUTCOMES: Retention rates were high in the intervention (93%) and control (84%) study arms, and 87% of parents reported that they would highly recommend PTT to a friend. At 9-month follow-up, intervention parents reported lower parenting stress (β = 15.83, 95% confidence interval [CI] 29.57, 2.07, p = 0.02) and greater self-efficacy in managing their child's behaviour (β = 0.16, 95% CI 0.002, 0.33, p = 0.05) than control parents. PTT had minimal influence on children's weight-related behaviours and BMI. CONCLUSIONS:The results suggest that PTT can feasibly be implemented and tested in the Canadian context. Preliminary impact results suggest that the program may be effective in changing general parenting; however, program content should be modified to adequately address children's weight-related behaviours.

Nutrigenetics research is anticipated to lay the foundation for personalized dietary recommendations; however, it remains unclear if providing individuals with their personal genetic information changes dietary behaviors. Our objective was to evaluate if providing information for a common variant in the fatty acid desaturase 1 (FADS1) gene changed omega-3 fatty acid (FA) intake and blood levels in young female adults (18–25 years). Participants were randomized into Genetic (intervention) and Non-Genetic (control) groups, with measurements taken at Baseline and Final (12 weeks). Dietary intake of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) was assessed using an omega-3 food frequency questionnaire. Red blood cell (RBC) FA content was quantified by gas chromatography. Implications of participation in a nutrigenetics study and awareness of omega-3 FAs were assessed with online questionnaires. Upon completion of the study, EPA and DHA intake increased significantly (p = 1.0 × 10−4) in all participants. This change was reflected by small increases in RBC %EPA. Participants in the Genetic group showed increased awareness of omega-3 terminology by the end of the study, reported that the dietary recommendations were more useful, and rated cost as a barrier to omega-3 consumption less often than those in the Non-Genetic group. Providing participants FADS1 genetic information did not appear to influence omega-3 intake during the 12 weeks, but did change perceptions and behaviors related to omega-3 FAs in this timeframe.

This cross-sectional study explores associations between mothers’ and fathers’ food parenting practices and children’s nutrition risk, while examining whether family functioning modifies or confounds the association. Home observations assessed parents’ food parenting practices during dinnertime (n = 73 families with preschoolers). Children’s nutrition risk was calculated using NutriSTEP®. Linear regression models examined associations between food parenting practices and NutriSTEP® scores. An interaction term (family functioning × food parenting practice) explored effect modification; models were adjusted for family functioning to explore confounding. Among mothers, more frequent physical food restriction was associated with higher nutrition risk in their children (β = 0.40 NutriSTEP® points, 95% Confidence Interval (CI) = 2.30, 7.58) and among both mothers and fathers, positive comments about the target child’s food were associated with lower nutrition risk (mothers: β = −0.31 NutriSTEP® points, 95% CI = −0.54, −0.08; fathers: β = −0.27 NutriSTEP® points, 95% CI = −0.75, −0.01) in models adjusted for parent education and child Body Mass Index (BMI) z-score. Family functioning did not modify these associations and they remained significant after adjustment for family functioning. Helping parents to use positive encouragement rather than restriction may help to reduce their children’s nutrition risk.

BackgroundEating meals, particularly dinner, with family members has been found to be associated with improved dietary intake, lower prevalence of disordered eating behaviors, lower levels of substance abuse, and improved academic outcomes among adolescents. Limited research has examined how the frequency of family meals has changed over time. The objective of this study was to examine secular trends in family dinner frequency over a 12-year period using a large, nation-wide sample of adolescents.MethodsUsing data from two cohorts of the Growing up Today study (GUTS; n = 18,075 observations for 14,79,714 and 15 year olds), we compared family dinner frequency among 14–15-year-olds in 1996 (GUTS1) through 2008 (GUTS2) and rate of change in family dinner frequency from 1996 to 1998 (GUTS1) and 2004–2008 (GUTS2). We fit logistic models using generalized estimating equations with independence working correlation and empirical variance to account for correlation within individual and between siblings.ResultsFrom 1996 to 2008, the number of family dinners per week among males decreased from 5.3 to 4.6 (p = 0.04) and among females from 5.0 to 4.4 (p = 0.03). We found that the rate of decline in frequency of family meals was consistent in GUTS1 (1996–1998) and GUTS2 (2004–2008) among both males and females.ConclusionsFrom 1996 to 2008, frequency of family dinners decreased among adolescents. Future research should explore reasons for this decline as well as strategies to increase family meals among adolescents.
