Data for: Age and an obesogenic diet affect mouse behaviour in a sex-dependent manner

Behavioural data from the open field, elevated plus maze and social preference tasks was collected using a ceiling mounted webcam over the testing apparatus followed by manual experimenter counting, blind to cohort where possible. Food, calorie and protein intake for a cage of mice was determined by measuring food weekly over a 24 hour period and expressed as intake per day per gram of the total weight of mice in each cage. Body weight of individual mice was monitored weekly from weaning to the end of the experimental period. A subset of the females and males in the two diet groups were used to quantify total body fat and lean mass by Dual Energy X-ray Absorptiometry (DEXA) scanning (Lunar PIXImus densitometer; GE Healthcare) and/or to measure the weights of the individual fat deposits and body organs. All data sets were added to an Excel spreadsheet and statistical comparisons between groups were made using GraphPad Prism (version 9).
