This study was a cross-sectional study to examine problematic mealtime behaviors among children with autism spectrum disorder (ASD) in Florida. Forty-one parents completed a 48-item survey. The mean age of their children was 8.1 years and 73% were male. The data were divided and compared by age group: Ages 2–6, 7–11, and 12–17. Data from the 3- to 6-year-old children were extracted and compared with the references from Provost et al. (2010). There were age differences in eating difficulties at home (p = 0.013), fast food restaurants (p = 0.005), and at regular restaurants (p = 0.016). The total mealtime behavior score was significantly higher in early childhood (p < 0.001) and mid-childhood (p = 0.005) than adolescents. More parents of ages 3–6 with ASD reported difficulties with breastfeeding (p < 0.01); concerns about eating (p < 0.001); difficulties related to mealtime locations (p < 0.05), craving certain food (p < 0.05), and being picky eaters (p < 0.01) compared to typically developing children. The total mealtime behavior score was significantly higher in children with ASD than typically developing children (p < 0.001). The results indicate that early childhood interventions are warranted and further research in adolescents is needed.

This study investigates the link between process evaluation components and the outcomes of a school-based nutrition curriculum intervention, ‘Choice, Control and Change’. Ten New York City public middle schools were recruited and randomly assigned into intervention or control condition. The curriculum was to improve sixth to seventh grade students’ energy balance related behaviors, based on social cognitive and self-determination theories, and implemented during the 2006–2007 school year (n = 1136). Behaviors and psychosocial variables were measured by self-reported questionnaires. Process components were evaluated with classroom observations, teacher interviews, and a student questionnaire. Using ‘Teacher Implementation’ (dose delivered) and ‘Student Reception’ (dose received) process data; intervention group was further categorized into medium- and high-implementation groups. Analysis of covariance revealed that, compared with control group, only high-implementation group showed significant improvement in students’ behavior and psychosocial outcomes. Hierarchical linear models showed that ‘Teacher Implementation’ and ‘Student Reception’ significantly predicted students’ sweetened beverage outcomes (P < 0.05). ‘Student Satisfaction’ was also greater when these implementation components were higher, and significantly associated with behavior and psychosocial outcomes (P < 0.05). Implementation process influenced the effectiveness of the ‘Choice, Control and Change’ intervention study. It is important to take into account the process components when interpreting the results of such research.

Understanding dietary patterns in the study of diet-disease relationships is crucial for designing dietary behaviour interventions. This study aimed to determine associations between dietary patterns and background characteristics among school age children (9–15 years) in Ghana. A cross-sectional sample of 487 urban-dwelling children age 9–15 years was recruited using simple random sampling from 24 schools (12 private and 12 public) in the Ga-East Municipality in Southern Ghana. A 7-day food frequency questionnaire was used to record children’s consumption of over 100 unique food items. Principal component analyses based on 14 food groups was used to describe emerging dietary patterns (DP). BMI-for-age z-scores segregated by sex were derived using WHO Anthro plus software. Linear regression was used to test associations between ‘diet factor’ scores, and weight status controlling for age. Four DPs were identified that explained 53.2% of variation in the diets of children: (1) energy dense; (2) starchy root staple and vegetables; (3) cereal-grain staples and poultry; and (4) fish & seafoods. Energy dense DP characterised by processed meat, fried foods, and sugary foods was associated with child overweight/obese status after controlling for age, sex, SES and school type [F(5, 484) = 6.868, p < 0.001]. Starchy root with vegetable DP was negatively associated with overweight/obese status, private school attendance and higher SES after controlling for age at bivariate level. However, relationship between ‘starchy root staples and vegetables’ DP and overweight/obese status lost significance after controlling for other covariates. Our data identified energy-dense dietary pattern to be significantly associated with childhood overweight and obesity. Targeted dietary messages are required to address energy-dense dietary patterns among school-age children.
