Abbreviations, MET-mins/week = MET level × minutes per day × days per week, where 1 MET is equivalent to resting energy expenditure (MET level, walking, 3.3, moderate 4.0 and vigorous 8.0) a P values from 2-sample t tests for continuous variables or from chi2 tests for categorical variables b Body mass index, measured as weight in kilograms divided by height in meters squared c Numbers may vary due to missing values or incorrectly completed surveys as participants were given a 'prefer not to answer' option for income. d n = 110 intervention and n = 106 controls correctly completed food frequency questionnaires e n = 89 intervention and n = 89 controls correctly completed IPAQ activity questionnaires |
