520 body composition analyzer

Four visits were required at the CHU de Quebec—Université Laval Research Center after an 8-h overnight fast, at week 0 and week 6 for the first intervention period, and at week 12 and week 18 for the second intervention period. Measurements and clinical investigations were identical for each study visit. Body weight and BMI were collected; waist circumference was measured using the mean of 2 measures at the top of the iliac crest, while the subject was standing. Body composition was evaluated, in the fasting state and at the same time across visits, using a 4-electrode bioimpedance scale (InBody 520 Body Composition Analyzer). At each visit, subjects were instructed to complete a validated FFQ containing 91 items and 33 subquestions (18 (link)). Energy and nutrient intake were analyzed using the Nutrition Data System for Research and the Canadian Nutrient File 2015 (19 ). Foods consumed were categorized into the following food groups: fruits and vegetables, cereals and grains, dairy products, and meats and substitutes, as per Canada's Food Guide for Healthy Eating 2007 (17 ). Physical activity was assessed using an auto-administered questionnaire containing 10 items; however, the data were deemed unsuitable for analysis owing to multiple inconsistencies in reporting and missing values.
