The REDB was quantified with the SCOFF questionnaire.
In relationship to REDB, a group of 852 students (32.5%; CI95%: 30.7%-34.3%) obtained risk scores for these disorders.
Except for socioeconomic level, religiosity, and level of physical activity, the remaining variables showed association among these risk factors and REDB.
Table 2 shows that in the multivariate analysis, the variables: problematic consumption of alcohol, female sex, consumption of any illegal substance at any moment in life, non-heterosexual sexual orientation, depressive symptoms with clinical importance, cigarette smoking at any moment in life, and family dysfunction were associated to REDB, with OR values between 1.84 and 1.24.
This study showed that approximately one third of adolescent students are under REDB. The risk is significantly higher in students with problematic consumption of alcohol and in women.
Likewise, this study showed that age was independent of REDB. The few studies available in this population are contradictory: Herpertz-Dahlmann et al., (4) and Unikel et al., (16) observed that REDB increased with age, while Gonzalez-Juarez et al., (17) and Vega et al., (18) found that this risk diminished with age.
In the current research it was noted that women showed a higher proportion of REDB compared to men; said data agrees with most.
Our results revealed that socio-economic level was independent of REDB, a similar observation to that reported by Angel et al.
Consumption of legal (alcohol and cigarettes) and illegal substances is related to REDB, although no studies were found with adolescent population exploring these associations, research with university students suggests that consumption of substances can be a strategy to lower anxiety and food intake.
In our research, religiosity and physical activity did not show statistically significant relationship with REDB. The religious beliefs or convictions can be important factors in REDB in some contexts, above all in that related to self-punishments and sacrifices in some religions.
The findings from the current study corroborate the complexity of the problem of eating behavior disorders in adolescent populations, which is why it is necessary for the strategies of promoting healthy eating behavior and prevention and reduction of REDB to be comprehensive, with an interdisciplinary approach and guaranteeing participation from different sectors to encompass all the aspects involving this problem.
(7) From this study, it may be concluded that the prevalence of REDB is high in adolescent students from Cartagena, Colombia.
