Adolescence, with its change in dietary habits, is likely to be a vulnerable period in the onset of obesity. It is considered that peers have an important role to play on adolescents’ diet, however, limited research has examined the role of peers in this context. This study examined the relationship between self-efficacy for healthy eating, parent and peer support for healthy and unhealthy eating and food intake patterns. Participants were 264 boys and 219 girls (N = 483), aged 13-18 years, recruited from post-primary schools in Ireland. Self-report measures assessed self-efficacy, parent and peer support for healthy eating, and for unhealthy eating. Dietary pattern analysis, a popular alternative to traditional methods used in nutritional research, was conducted on a FFQ to derive food intake patterns. Two patterns were identified labeled ‘healthy food intake’ and ‘unhealthy food intake’. Multi-group modelling was used to evaluate whether the hypothesized model of factors related to dietary patterns differed by gender. The multi-group model fit the data well, with only one path shown to differ by gender. Lower self-efficacy for healthy eating and higher peer support for unhealthy eating were associated with ‘unhealthy food intake’. Higher self-efficacy was associated with ‘healthy food intake’. Prevention programs that target self-efficacy for eating and peer support for unhealthy eating may be beneficial in improving dietary choices among adolescents.

ABSTRACT: BACKGROUND: Levels of knowledge about diabetes mellitus (DM) among newly diagnosed diabetics in Bangladesh are unknown. This study assessed the relationship between knowledge and practices among newly diagnosed type 2 DM patients. METHODS: Newly diagnosed adults with type 2 diabetes (N = 508) were selected from 19 healthcare centers. Patients’ knowledge and self-care practices were assessed via interviewer-administered questionnaires using a cross-sectional design. Knowledge questions were divided into basic and technical sections. Knowledge scores were categorized as poor (mean + 1 SD). Chi square testing and multivariate logistic regression were conducted to examine the relationship between diabetes-related knowledge and self-care practices. RESULTS: Approximately 16%, 66%, and 18% of respondents had good, average, and poor (GAP) basic knowledge respectively and 10%, 78%, and 12% of respondents had GAP technical knowledge, about DM. About 90% of respondents from both basic and technical GAP did not test their blood glucose regularly; a significant relationship existed between basic knowledge and glucose monitoring. Technical knowledge and foot care were significantly related, though 81% with good technical knowledge and about 70% from average and poor groups did not take care of their feet. Approximately 85%, 71%, and 52% of the GAP technical knowledge groups, consumed betel nuts; a significant relationship existed between technical knowledge and consumption of betel nuts. Around 88%, 92%, and 98% of GAP technical knowledge groups failed to follow dietary advice from a diabetes educator. About 26%, 42%, and 51% of GAP basic and technical sometimes ate meals at a fixed time (p < 0.05). Approximately one-third of respondents in each basic knowledge group and 29%, 32%, and 32% of GAP technical knowledge groups partially followed rules for measuring food before eating. Total basic knowledge (TBK) and business profession were significant independent predictors of good practice. OR for TBK: 1.28 (95% CI: 1.03 to 1.60,); OR for business profession 9.05 (95% CI: 1.17 to 70.09). CONCLUSIONS: Newly diagnosed type 2 diabetics had similar levels of basic and technical knowledge of DM. Health education and motivation should create positive changes in diabetes-control-related self-care practices. HubMed – eating

This study had two objectives. First, to determine links between levels of eating psychopathology and beliefs about exercise among young women. Second, to determine the predictive effects of unhealthy core beliefs on exercise beliefs.A convenience sample of 185 young female exercisers completed the Eating Disorders Inventory (EDI), the Exercise Beliefs Questionnaire (EBQ) and the Young Schema Questionnaire (YSQ).The participants’ mean scores on the EDI were as follows: drive for thinness=0.69 (SD=0.82); body dissatisfaction=1.30 (SD=0.86); and bulimia=0.33 (SD=0.42). There were significant, positive correlations of all three EDI scales with EBQ social and EBQ appearance subscales. In addition, YSQ Defectiveness/Shame beliefs predicted EBQ social scores, while YSQ Unrelenting Standards predicted EBQ appearance scores.Those women with relatively unhealthy eating attitudes are likely to believe that exercise will prevent negative social consequences, and are likely to be motivated to exercise in order to preserve or enhance their physical appearance. These same types of exercise belief (regarding social consequences and appearance) are predicted by feelings of defectiveness and shame and by unrelenting high personal standards.

Examining the moderating role of social norms between body dissatisfaction and disordered eating in college students.

Filed under: Eating Disorders

Eat Behav. 2013 Jan; 14(1): 73-8
Forney KJ, Ward RM

Body dissatisfaction is a well-replicated risk factor for disordered eating, yet not all individuals with body dissatisfaction exhibit disordered eating. This study examined the role of perceptions of social norms on the relationship between body dissatisfaction and disordered eating. Perceptions of descriptive and injunctive peer norms, body dissatisfaction, and disordered eating were examined in a non-clinical sample of college men and women using cross-sectional survey methods. For women, perceptions of the injunctive norms of peer thinness and peer acceptability moderated the relationship between body dissatisfaction and disordered eating with an additive effect; perceptions of the descriptive norm peer prevalence of disordered eating behaviors did not. In men, norms did not moderate the relationship between body dissatisfaction and disordered eating. Endorsement of injunctive norms is associated with reported disordered eating in women with high body dissatisfaction. Norm-based interventions may be best suited for women with high body dissatisfaction.
