Drive for muscularity and disordered eating behaviors and its relationship with anthropometric indicators and physical activity in Mexican adolescent men

PURPOSE

Adolescent men have been identified as a risk population to develop eating disorders and other psychopathologies as drive for muscularity (DM) recently considered as muscularity-oriented disordered eating. It is important to identify risk factors as precursors of these pathologies. The aim of this study was to determine the risk of developing disordered eating behaviors (DEB) and DM and its relationship with anthropometric indicators and physical activity (PA) in adolescent men (high-school students, age 15-19) from Hidalgo, Mexico.

METHODS

A cross sectional, descriptive, and correlational field study was carried out in a non-probabilistic sample of 267 Mexican adolescents aged 15-19 years. Participants completed measures of DM, DEB, and PA. Each subject was weighted and heighted to calculate body mass index (BMI), body fat percentage, and fat-free mass index (FFMI).

RESULTS

Adolescents in the DM risk category (OR 8.28, CI 2.71-25.22) had significantly greater odds of developing DEB, while adolescents with higher BMI scores (OR 1.28, CI 1.14-1.45) tended to be more likely of developing DEB. The results showed that DEB and moderate PA were associated with DM; adolescents who engaged in DEB had an 8.64 times (CI 3.05-24.52) higher risk of developing DM. Participants classified in the category of highest moderate PA (OR 2.66, CI 1.26-5.59) had significantly greater odds of developing DM.

CONCLUSION

Important percentages of the risk of developing DEB and DM were determined in Mexican adolescent men. In agreement with other findings, there were no associations between anthropometric indicators and DM.

Translation and validation of the Diabetes Eating Problem Survey to screen eating disorders in patients with type-1 diabetes mellitus

INTRODUCTION

The treatment of type-1 diabetes mellitus (T1DM) requires changes in patients' eating habits and lifestyles which could lead to the development of an eating disorder (ED). An early detection of these disorders in subjects with T1DM is necessary. However, there is no specific questionnaire concerning the presence of an ED in these patients.

OBJECTIVES

To translate and validate for the Spanish population a specific questionnaire aimed at detecting the risk of onset of an ED on a sample of subjects with T1DM. To analyze its agreement with its shortened version and with the gold standard tool, EAT-26.

MATERIAL AND METHODS

Cross-sectional study. The study population consisted of 112 adults with T1DM. The EAT-26 tool and DEPS-R questionnaire were used to detect subjects at risk for developing ED. In addition, several characteristics such as weight, height, BMI, age and age of onset were assessed by means of self-administered questionnaires, in order to study their correlation with test scoring.

RESULTS

Structural properties of the tests were evaluated through methodological procedures aimed at calculating reliability and validity. The translated and adapted version had a high consistency in both its complete and summarized version (α=0,821).The test-retest also yielded consistent results (intraclass correlation coefficient 95.8% for EPAD and 92.3% for EPAD-R). The factor analysis yielded 5 factors: 1) Eating attitudes; 2) Bulimic behavior; 3) Weight control; 4) Avoidance, and 5) Restriction.

CONCLUSIONS

We have developed a questionnaire in Spanish capable of identifying the risk of onset of a specific ED in patients with T1DM. The EPAD-R questionnaire detected 10% more cases and different ones than those detected by the EAT-26 test. It is necessary to use specific screening tools to correctly identify eating disorders in patients with T1DM.
