We had seven prespecified primary outcomes: fibre intake, combined fruit and vegetable intake, Healthy Eating Index, moderate-to-vigorous physical activity, sedentary time, BMI, and waist circumference.For dietary intake, participants completed three unannounced, randomly timed, telephone-administered 24-h recall interviews with bilingual (English and Spanish) registered dietitians at each of the three data collection timepoints. We used Nutrient Data System for Research software (version 2020; Nutrition Coordinating Center (NCC), University of Minnesota, Minneapolis, MN, USA) to administer the dietary inter views and calculate dietary intake outcomes, including fibre. Estimates of combined fruit and vegetable intake excluded juice, avocados, French fries, and fried onion rings. The Healthy Eating Index (HEI-2010) was calculated on the basis of 13 dietary components, with higher scores indicating better compliance with national dietary guidelines.For anthropometrics, participant height was measured with a portable stadiometer (Seca 213 Portable Stadiometer; Seca, Hangzhou, China), accurate to the nearest 0·1 cm. Bodyweight was measured with a digital platform scale (Seca 876 Digital Scale; Seca) to the nearest 0·23 kg (0·5 lb). Waist circumference was measured at the superior border of the iliac crest, using a cloth tape to the nearest 0·1 cm, while the participant was standing. BMI was calculated as kg/mFor physical activity, participants wore thigh-mounted ActivPAL3 accelerometers (PAL Technologies, Glasgow, UK) for 7 days after each assessment timepoint.Our secondary outcomes were perceived stress and anxiety. Perceived stress was measured using the Perceived Stress Scale 10 (PSS-10). The range of PSS-10 is between 0 and 40, with lower scores denoting lower stress levels and higher scores higher stress levels.
