The International Journal of Behavioral Nutrition and Physical Activity, vol. 14, p. 1-11.
Intentions : «[T]he objective of the present study was to [...] assess the impact of a web-based version of Team Nutriathlon, an innovative web-based nutrition intervention, on the consumption of V/F [vegetables and fruit] and M/A [milk and alternatives] and [...] identify facilitators and/or barriers influencing its success among high school students.» (p. 3)
Échantillon/Matériau : «A total of 282 students (61% female) participated in the study with 193 students (62% female) in the intervention and 89 students (58% female) in the control group.» (p. 6) Authors recruited «10 classes of grades secondary I and II (grades 7 and 8) from three different high schools in Québec City, Canada.» (p. 3)

«Throughout the duration of Team Nutriathlon, students were introduced to strategies that enabled them to more easily achieve their goals. In our study, students reported that the strategies provided by teachers, parents, researchers and those discovered by themselves were factors facilitating the consumption of V/F and M/A. Developing strategies or “practical skills” (e.g. adding more V/F in the lunch box) and obtaining support from teachers and parents would allow students to increase their V/F consumption.» (p. 8) «During interviews, [s]everal students mentioned the importance of parental input during the program. Moreover, parents were involved in different ways with the adolescents by encouraging them to eat more V/F and M/A, reminding them to note their results on the website, increasing the amount of V/F during meals at home and in lunch boxes and buying more healthy foods at the grocery store.» (p. 7) Indirectly, this study indicates that «[p]arents, through their influence on food accessibility, support and being a role model may directly influence the consumption of certain foods.» (p. 8)

Obesity Research, vol. 13, no 9, p. 1624-1629.
Intentions : « It is commonly recognized that genetic, environmental, behavioral, and social factors are involved in the development of obesity. The family environment may play a key role in shaping children’s eating behaviors. The purpose of this study was to estimate the degree of familial resemblance in eating behavioral traits (cognitive dietary restraint, disinhibition, and susceptibility to hunger). » (p. 1624)
Échantillon/Matériau : « 282 men and 402 women (202 families) from the Quebec Family Study. » (p. 1624)
Instruments : « Eating behavioral traits were assessed with the Three-Factor Eating Questionnaire [...] » (p. 1624)

« The pattern of familial correlation showed significant spouse correlation for the three eating behavior phenotypes, as well as significant parent-offspring and sibling correlations for disinhibition and susceptibility to hunger. According to the most parsimonious model, generalized heritability estimates (including genetic and shared familial environmental effects) reached 6%, 18%, and 28% for cognitive dietary restraint, disinhibition, and susceptibility to hunger, respectively. [...] These results suggest that there is a significant familial component to eating behavioral traits but that the additive genetic component appears to be small, with generalized heritability estimates ranging from 6% to 28%. Thus, non-familial environmental factors and gene-gene and gene-environmental interactions seem to be the major determinants of the eating/behavioral traits. » (p. 1624)
