The roles of child temperament, parent stress, and parenting style in family mealtimes.

Family mealtimes are associated with benefits for children, including healthy eating, fewer behavior problems, and healthy psychological well-being. However, the interactions during family mealtimes, and the parent and child characteristics, which may affect both the family mealtime environment and the associated benefits in children are not fully understood. The goal of this study was to examine the role of child and parent characteristics on the family mealtime environment. We tested several mediation models to explain how child temperament (negative affectivity), parent stress, and the dimensions of parent feeding style (responsiveness and demandingness) interact and influence each other to impact the structure and quality of the mealtime environment. Parents (68 mothers; 82 fathers) of children between 2 and 6 years completed an online survey. Measures included the Children's Behavior Questionnaire, Perceived Stress Scale, Caregiver's Feeding Styles Questionnaire, and The Meals in Our Household Questionnaire. Child negative affectivity was associated with poorer mealtime quality and structure. These associations were mediated through parent responsiveness, but not demandingness. The role of demandingness in family mealtimes may depend on parent responsiveness. When examined together in a serial mediation model, child negative affectivity increased parent stress, which reduced responsiveness, and led to poorer mealtime quality and structure. These results emphasize the complex relationships between child temperament, parent stress, and the dimensions of parenting styles that occur within the mealtime context. This line of research is essential for understanding family mealtime dynamics and informing future studies aimed at creating positive interactions between parents and children during mealtimes.

BMI and disordered eating in urban, African American, adolescent girls: The mediating role of body dissatisfaction.

OBJECTIVE: This study examined the mediating role of body dissatisfaction between Body Mass Index (BMI) and subsequent disordered eating (e.g. dieting and restricting/purging) among early adolescent African American girls. STUDY DESIGN: Participants included 701 African American girls in 6th and 7th grades in urban schools serving low-income communities, mean age 12.15 (SD = 0.72) years. Participants were assessed at baseline and approximately 6 months later. Objectively measured height and weight were used to calculate BMI z-score. Participants completed questionnaires on body size dissatisfaction and recent dieting and restricting/purging behaviors. RESULTS: At baseline, 51.5% of participants were overweight/obese, and 60.4% expressed body dissatisfaction and a desire to be smaller. Path analytic analyses revealed change in body dissatisfaction significantly mediates the relation between initial BMI z-score and increases in dieting behaviors (B = 0.924, SE = 0.280, p = 0.001) but not restricting/purging behaviors (p = 0.05). CONCLUSIONS: Body dissatisfaction explains some associations between excess body weight and subsequent disordered eating symptoms among early adolescent, African American girls. Body dissatisfaction, identified by screening, may be an indicator of further negative consequences, including disordered eating behaviors.

The perceived and built environment surrounding urban schools and physical activity among adolescent girls.

BACKGROUND: Neighborhood perceived/built environment and physical activity (PA) associations have been examined for adolescents around homes, but not surrounding schools. PURPOSE: The purpose of this paper is to examine if positive perceptions/built environment in neighborhoods surrounding schools predict PA among low-income, urban adolescent girls. METHODS: Measures include: minutes in moderate-vigorous PA (MVPA, ankle accelerometry), perceptions of the school environment (questionnaire), built environment (neighborhood audit). Analyses include multi-level models. RESULTS: Two hundred twenty-four sixth and seventh grade girls [mean(sd) age = 12.1(0.7) years] from 12 schools serving low-income, primarily African American communities; mean MVPA 35.4 min (mean days assessed = 5.8). Girls in schools with more positive perceptions of the neighborhood environment surrounding the school were less active (ß = 7.2, p = 0.043). Having "places to go within walking distance" (perceptions) and number of food stores near school (built environment) positively relate to MVPA (ß = 5.5, p = 0.042 and ß = 0.59, p = 0.047). CONCLUSIONS: Among neighborhoods surrounding urban schools, positive perceptions do not predict PA; accessibility, via both perceived and built environment, support PA.
