"Extreme dietary restraint" and "excessive exercise" were reported by 3.4%and4.9%9% of participants, respectively.
Under such an illness history, behavioral problems such as food refusal, food hoarding, falsification of dietary intake, and excessive exercise were more prominent in the S group.
The definition of excessive exercise was exercising on greater than 19 days out of 28 days, and was calculated using information on both intensity and duration (kcal/15 mins) [ 14].
For binge eating, self-induced vomiting, and purging behaviours, "regular" was defined as "at least weekly", whereas regular extreme dietary restriction and excessive exercise were recognised if these behaviours occurred, on average, 3 or more times per week [ 34].
Food refusal and purging were symptoms common to both eating disorder groups during hospitalization, but falsification of dietary intake amounts, food hoarding, and excessive exercise were observed more frequently in the S group.
Our data show that excessive exercising is significantly overrepresented in individuals in which ADHD symptoms in childhood have not persisted into adulthood.
Excessive exercising was significantly associated with childhood only ADHD compared to no ADHD with an odds ratio of 3.239 even after controlling for socio-demographic variables, BMI, eating related and general psychopathology.
Multinomial logistic regression analyses revealed that a mean score on the EDS-G above the proposed cutoff for excessive exercising was significantly associated with coADHD compared to noADHD with an odds ratio of 3.239 even after controlling for socio-demographic variables, BMI, eating related (EDE-Q) and general psychopathology (PHQ-4).
Last but not least, excessive exercise, which is typical in AN patients, may be considered a restless or hyperactive behavior.
