Body dissatisfaction and disordered eating among Portuguese and Spanish adolescents: The role of individual characteristics and internalisation of sociocultural ideals.

The aim of this study was to explore the differences in patterns of risk factors for body dissatisfaction and disordered eating attitudes in both female and male adolescents from Portugal and Spain. The sample included 455 adolescents aged 12-16 years (M = 13.28, SD = 0.65) from two urban areas of each country. Body mass index, self-reported self-esteem, perfectionism, internalisation of sociocultural ideals, body dissatisfaction and disordered eating attitudes were assessed. Path analyses provided partial support for a cross-cultural model of body dissatisfaction and disordered eating in Western countries due to the presence of certain differences in the patterns of relationships across sex and country. The findings suggest the importance not only of identifying cultural specificities, even in "neighbouring" countries, but also of developing a global and comprehensive preventive approach that focuses on the influence of the ideal of beauty transmitted by Western societies.

Assessment of two school-based programs to prevent universal eating disorders: media literacy and theatre-based methodology in Spanish adolescent boys and girls.

AIMS: To evaluate the long-term effects of two school-based prevention programs administered to a universal mixed-sex sample of school-going adolescents on disturbed eating attitudes, aesthetic ideal internalization, and other eating disorder risk factors, when compared to a control group. METHODS: Participants were 200 adolescents aged 12-15 selected by means of incidental sampling from second-year compulsory secondary education at schools. An interactive multimedia media literacy program (ML + NUT, Media Literacy and Nutrition) and a program focused on the same topics using dramatic arts (Theatre Alive) were applied and compared with a control group. Pretest, posttest (1 month later), and 5- and 13-month follow-up measurements were taken. Analyses were conducted with two-way mixed 3 × 3 ANCOVA (group × phase) adjusted by baseline levels, body mass index, and sex. RESULTS: Participants in both experimental groups showed significantly higher self-esteem scores than the control group over time. The ML + NUT group also presented lower aesthetic ideal internalization scores than the control group. DISCUSSION: Both programs can benefit students' self-esteem. Moreover, ML + NUT program was useful in reducing thin-ideal internalization. However, differences in body dissatisfaction and disordered eating attitudes were not found. The programs may be protective on the core psychological variables, which are essential to adaptive adolescent development.

Pilot assessment of two disordered eating prevention programs. Preliminary findings on maladaptive beliefs related to eating disorders.

AIMS: As eating disorders have severe consequences, they require prevention. We aimed to compare maladaptive beliefs related to eating disorders by following two programs based on media literacy in adolescents at post-test intervention, and after 6 and 12month-follow-ups. The Male and Female Nutrition and Media Literacy Model preventive program (NUT+MEF+MEM+ML in Spanish) and the Theater Alive program are both based on the same contents, the former being presented in a multimedia and interactive format and the latter in a drama format. Both were compared to a control group without intervention, whose participants received usual classes before the assessments. METHOD: Participants were 178 adolescents in the second year of compulsory secondary education from fours schools of Terrassa (Catalonia, Spain). All participants in each school were assigned to the same group, depending on school schedules. A mixed 3 (group: Theater Alive, NUT+MEF+MEM+ML, control)×3 (time: post-test, 6-month-follow-up, 12-month-follow-up) factorial design was used to evaluate the effect on maladaptive beliefs measured using a CE-TCA tool. RESULTS: When compared to the control group, both Theater Alive (d=0.88) and NUT+MEM+MEF+ML (d=0.60) obtained lower scores over time, the latter being not statistically significant. DISCUSSION: The Theater Alive program may produce an effect of cognitive dissonance that might eliminate the discrepancy between the contents of the play and those that are internalized, thus modifying maladaptive beliefs. Participants in the Theater Alive program, as actors in front of an audience, had to defend certain content that was rehearsed over and over again to the point until it became internalized.

Association of biological, psychological and lifestyle risk factors for eating disturbances in adolescents.

We aimed to assess the association of several risk factors for eating disturbances in adolescents. Participants were 448 girls and boys aged 12-15 years. Being female, higher body mass index, internalisation of standard of appearance, perfectionism, body dissatisfaction, number of lifetime addictive behaviours and lower self-esteem were associated with higher eating disturbance scores, whereas frequency of sedentary behaviours and physical activity were not (R(2) ⩾ 41%). Findings suggest the need to guide prevention efforts towards the broad spectrum of individual potentially modifiable factors. A non-specific comprehensive perspective may be adequate to prevent problems related to weight, body image and drug use.

Gender differences found in a qualitative study of a disordered eating prevention programme: What do boys have to say?

Qualitative studies examining gender differences of eating disorder prevention programmes are scarce. We aimed to evaluate gender differences in adolescents who participated in a larger study on effectiveness of a disordered eating prevention programme. Perceptions of eating, female and male aesthetic models, media influences, prevention programmes and emerging topics from 12 school-going boys who received a media-literacy programme (n = 4), media-literacy plus nutrition-awareness programme (n = 4) or neither (n = 4) were explored using Interpretative Phenomenological Analysis and compared with previous results in girls. Findings suggest that the prevention programme is effective for both genders. Gender differences and consumer-culture influences may be considered in future interventions.

Moderate-vigorous physical activity across body mass index in females: moderating effect of endocannabinoids and temperament.

BACKGROUND: Endocannabinoids and temperament traits have been linked to both physical activity and body mass index (BMI) however no study has explored how these factors interact in females. The aims of this cross-sectional study were to 1) examine differences among distinct BMI groups on daytime physical activity and time spent in moderate-vigorous physical activity (MVPA), temperament traits and plasma endocannabinoid concentrations; and 2) explore the association and interaction between MVPA, temperament, endocannabinoids and BMI. METHODS: Physical activity was measured with the wrist-worn accelerometer Actiwatch AW7, in a sample of 189 female participants (43 morbid obese, 30 obese, and 116 healthy-weight controls). The Temperament and Character Inventory-Revised questionnaire was used to assess personality traits. BMI was calculated by bioelectrical impedance analysis via the TANITA digital scale. Blood analyses were conducted to measure levels of endocannabinoids and endocannabinoid-related compounds. Path-analysis was performed to examine the association between predictive variables and MVPA. RESULTS: Obese groups showed lower MVPA and dysfunctional temperament traits compared to healthy-weight controls. Plasma concentrations of 2-arachidonoylglyceryl (2-AG) were greater in obese groups. Path-analysis identified a direct effect between greater MVPA and low BMI (b = -0.13, p = .039) and high MVPA levels were associated with elevated anandamide (AEA) levels (b = 0.16, p = .049) and N-oleylethanolamide (OEA) levels (b = 0.22, p = .004), as well as high Novelty seeking (b = 0.18, p<.001) and low Harm avoidance (b = -0.16, p<.001). CONCLUSIONS: Obese individuals showed a distinct temperament profile and circulating endocannabinoids compared to controls. Temperament and endocannabinoids may act as moderators of the low MVPA in obesity.

Qualitative findings in a long-term disordered eating prevention programme follow-up with school-going girls.

The assessment of eating disorder prevention-programmes has mainly been addressed quantitatively excluding complexity that may improve prevention. We compared perceptions of eating, female and male aesthetic-models, media influences, prevention-programmes and emerging topics among 12 young females who received a media literacy programme (N = 4), media literacy plus nutrition awareness programme (N = 4) or were assigned to a control condition (N = 4). Interpretative Phenomenological Analysis highlighted ego-syntonic eating-patterns and signs of internalization of the thin ideal. Findings provide invaluable and rich information to improve future iterations of the programme.
