Young Vegetarians Could Be At Risk For Disordered Eating

Using the results of Project EAT-II: Eating Among Teens, researchers from the College of Saint Benedict and Saint John's University, the University of Minnesota, and the University of Texas, Austin, analyzed the diets, weight status, weight control behaviors, and drug and alcohol use of 2,516 adolescents and young adults between the ages of 15 and 23. These participants had been part of Project EAT-I, an earlier survey of middle school and high school students from 31 Minnesota schools using in-class surveys, food frequency questionnaires, and anthropometric measures taken during the 1998-99 academic year.

Participants were identified as current (4.3%), former (10.8%), and never (84.9%) vegetarians. Subjects were divided into two cohorts, an adolescent (15-18) group and a young adult (19-23) group. They were questioned about binge eating and whether they felt a loss of control of their eating habits. More extreme weight control behaviors including taking diet pills, inducing vomiting, using laxatives, and using diuretics were also measured.

The authors found that among the younger cohort, no statistically significant differences were found with regard to weight status. Among the older cohort, current vegetarians had a lower body mass index and were less likely to be overweight or obese when compared to never vegetarians.

Among the younger cohort, a higher percentage of former vegetarians reported engaging in more extreme unhealthy weight control behaviors when compared to never vegetarians. Among the older cohort, a higher percentage of former vegetarians reported engaging in more extreme unhealthy weight control behaviors when compared to current and never vegetarians.

In the younger cohort, a higher percentage of current and former vegetarians reported engaging in binge eating with loss of control when compared to never vegetarians. In the older cohort, a higher percentage of current vegetarians reported engaging in binge eating with loss of control when compared to former and never vegetarians.

Writing in the article, Ramona Robinson-O'Brien, Assistant Professor, Nutrition Department, College of Saint Benedict and Saint John's University, St. Joseph, MN, states, “Study results indicate that it would be beneficial for clinicians to ask adolescents and young adults about their current and former vegetarian status when assessing risk for disordered eating behaviors. Furthermore, when guiding adolescent and young adult vegetarians in proper nutrition and meal planning, it may also be important to investigate an individual's motives for choosing a vegetarian diet.”

Behaviour therapy can calm irritable bowels

Lead researcher Dr. Jeffrey M. Lackner from the State University of New York, Buffalo said cognitive behavioral therapy was known to be a very promising treatment for IBS, with the current findings helping to identify which patients would likely maintain a positive response.

Lackner and his colleagues are conducting a larger, longer-term study, as the current study being a small one, it remains unclear how long the benefits of cognitive behavioral therapy may last i. e. do they carry over to 9 months, a year or more.

IBS symptoms include bouts of abdominal cramps, bloating and changes in bowel habits i. e. diarrhoea or constipation, or alternating episodes of both. While, no one knows the exact cause of the disorder, there are certain symptom triggers like particular foods, large meals and emotional stress.

Cognitive behavioral therapy helps IBS patients to recognize their symptom triggers and manage them. Other treatment options include general diet changes, like reducing gas-producing foods; fibre supplements, if constipation is a primary symptom; and anti-diarrhoeal medications, when diarrhoea is a primary symptom.

There are two prescription medications for specific IBS cases: Lotronex, for women with diarrhoea dominant IBS not responding to other treatments; and Amitiza, for constipation dominant IBS.

Around 20% of people have IBS symptoms, with women affected at about twice the rate of men
