Rate of feed consumption and daily eating duration were similar in the three treatments.
This positive interaction between distance travelled and eating duration means that, for a set of available resources, chimpanzees bypass less productive resources to select more productive ones, as has been previously shown in Saki monkeys (Cunningham and Janson 2007).
We then ran a linear regression to test whether social factors (female ratio and party size), tree density, and eating duration at the tree influenced going to the next closest resource or travelling longer distances.
The correlation coefficients were 0.98 (total length of eating), 0.99 (duration of eating, rumination and resting phases, total length of rumination and resting) and 1.00 (number of eating, rumination and resting phases).
Other variables of interest including age, gender, diagnosis, psychiatric and medical comorbidity, prior treatment, age at first symptoms, eating disorder duration, and current program treatment duration were collected from the health record at baseline using a standard, pre-tested abstraction form.
There were no statistically significant relationships between study site, age, eating disorder duration or BMI and whether or not the patient completed treatment.
Specifically, we investigated sleep duration, eating behaviour and circadian characteristics as well as ghrelin and leptin plasma values as possible markers of sleep and intake-related processes.
The aim was to investigate the behavioral (sleep duration, eating patterns and chronobiological characteristics) and hormonal (plasma ghrelin and leptin concentrations) factors which could explain the previously reported association between the CLOCK 3111T/C SNP and weight loss.
Psychosomatic syndromes correlated differently with both severity of eating symptomatology and duration of illness: therefore, DCPR could be effective to achieve tailored treatments.
However, the duration of eating, number of eating bouts, and timing of those bouts were not consistent across animals.
During each feeding bout of a focal animal, we recorded species and types of food eaten along with duration of feeding on that particular food item.
