Weight-based self-esteem (WBSE) is hypothesized to be the core cognitive feature of eating disorders. The Weight Influenced Self-Esteem Questionnaire (WISE-Q) was designed to measure the influence of a negatively perceived body image on multiple dimensions of self-esteem, which we believe to be one aspect of WBSE. Study 1 sought to determine the factor structure of the WISE-Q as well as to examine the reliability and concurrent validity of WISE-Q scores among eating disorder and undergraduate student participants. In Study 2, validity was further investigated by examining changes in WISE-Q scores with treatment. The WISE-Q has two factors representing generalized and expected WBSE. Evidence of internal and test-retest reliability was found. Also, the pattern of correlations between WISE-Q scores and other constructs was in line with predictions. As expected, WISE-Q scores improved with treatment yet remained high.

OBJECTIVE: To evaluate the association of sociodemographic factors and parental food consumption with children’s food intake. DESIGN: A cross-sectional survey. SETTING: A population-based study with a representative sample in a metropolitan region of Rio de Janeiro, Brazil. Parents’ socio-economic variables, age and education level and children’s age were obtained by face-to-face interviews. The parental food intake was assessed using an FFQ and the children’s food intake was assessed using two 24 h recalls. SUBJECTS: Children (n 366) aged 6-30 months and their parents. RESULTS: The hierarchical regression analysis indicated that parents’ age was positively associated with the intake of vegetables among children (? = 0·73, 95 % CI 0·11, 1·34), while parents’ educational level was positively associated with the intake of fats (? = 3·52, 95 % CI 0·04, 7·01) and negatively associated with the intake of beans (? = -13·98, 95 % CI -27·94, -0·03). The age of the children was positively associated with the intakes of meats and eggs (? = 2·88, 95 % CI 1·55, 4·22), sugars (? = 5·08, 95 % CI 1·85, 8·30) and coffee (? = 1·77, 95 % CI 0·71, 2·84), and negatively associated with the intake of vegetables (? = -2·12, 95 % CI -3·20, -1·05). The influence of parental food intake was observed for the food groups of breads, cereals and tubers (? = 0·06, 95 % CI 0·003, 0·12), beans (? = 0·11, 95 % CI -0·003, 0·22) and fruits (? = 0·10, 95 % CI 0·03, 0·16). Unfavourable socio-economic variables were associated with intakes of breads, cereals and tubers, vegetables, fruits, meats, sugars and coffee by children. CONCLUSIONS: Parental food intake is associated with children’s intake of cereals, beans and fruits independent of socio-economic status.

Increasing children’s lunchtime consumption of fruit and vegetables: an evaluation of the Food Dudes programme.

OBJECTIVES: Although previous research has shown that the Food Dudes programme increases children’s fruit and vegetable consumption at school, there has been limited evaluation of the extent to which changes are maintained in the long term. Furthermore, despite knowledge that the nutritional content of home-supplied meals is lower than that of school-supplied meals, little consideration has been given to the programme’s impact on meals provided from home. The present study therefore assessed the long-term effectiveness of the Food Dudes programme for both school- and home-supplied lunches. DESIGN: Two cohorts of children participated, one receiving the Food Dudes intervention and a matched control group who did not receive any intervention. Consumption of fruit and vegetables was assessed pre-intervention, then at 3 and 12 months post-intervention. Consumption was measured across five consecutive days in each school using weighed intake (school-provided meals) and digital photography (home-provided meals). SETTING: Fifteen primary schools, six intervention (n 1282) and seven control schools (n 1151). SUBJECTS: Participants were children aged 4-11 years. RESULTS: A significant increase in the consumption of fruit and vegetables was found at 3 months for children in the intervention schools, but only for those eating school-supplied lunches. However, increases were not maintained at 12 months. CONCLUSIONS: The Food Dudes programme has a limited effect in producing even short-term changes in children’s fruit and vegetable consumption at lunchtime. Further development work is required to ensure the short- and long-term effectiveness of interventions promoting fruit and vegetable consumption in children such as the Food Dudes programme.

The goal of the current study was to examine whether genetic and environmental influences on an important risk factor for disordered eating, weight and shape concern, remained stable over adolescence. This stability was assessed in 2 ways: whether new sources of latent variance were introduced over development and whether the magnitude of variance contributing to the risk factor changed. We examined an 8-item WSC subscale derived from the Eating Disorder Examination (EDE) using telephone interviews with female adolescents. From 3 waves of data collected from female-female same-sex twin pairs from the Australian Twin Registry, a subset of the data (which included 351 pairs at Wave 1) was used to examine 3 age cohorts: 12 to 13, 13 to 15, and 14 to 16 years. The best-fitting model contained genetic and environmental influences, both shared and nonshared. Biometric model fitting indicated that nonshared environmental influences were largely specific to each age cohort, and results suggested that latent shared environmental and genetic influences that were influential at 12 to 13 years continued to contribute to subsequent age cohorts, with independent sources of both emerging at ages 13 to 15. The magnitude of all 3 latent influences could be constrained to be the same across adolescence. Ages 13 to 15 were indicated as a time of risk for the development of high levels of WSC, given that most specific environmental risk factors were significant at this time (e.g., peer teasing about weight, adverse life events), and indications of the emergence of new sources of latent genetic and environmental variance over this period.
