Treatment and study plan

Educational talk about physical activity and nutritional recommendations before a critical period of fat gain in university students

Other

An intervention was performed emulating a traditional nutritional session from a primary healthcare center (public health system). Traditionally, this session lasts around 20 minutes and includes a body composition measurement, nutritional assessment, and a brief educational talk about healthy eating. Just the intervention group received a series of healthy recommendations specially focused on the National Holiday.

Primary outcomes

  1. Body composition measurements

    Time frame: 3 weeks

    Changes on fat mass measured by Dual X-ray Absorptiometry (DXA)

Secondary outcomes

  1. Feeding questionnaires and food guide recommendations

    Time frame: 3 weeks

    Changes on the Global Food Index. The Global Food Index is a 12-item frequency questionnaire assessing adherence to the Chilean Food Guide. Each item is scored from 1 (least healthy) to 10 (most healthy); total score range = 12 - 120. Higher scores indicate a healthier diet. Change is calculated as Week 3 minus Baseline.

  2. Feeding questionnaires and food guide recommendations

    Time frame: 3 weeks

    Changes on the KIDMED index (questionnaire establishes the adherence to the Mediterranean diet). The Mediterranean Diet Quality Index (KIDMED) contains 16 yes/no items (12 positive = +1; 4 negative = -1). Total score range = 0 - 12; higher scores denote better adherence to the Mediterranean diet (0-3 poor, 4-7 average, 8-12 good). Change is calculated as Week 3 minus Baseline.

  3. Feeding questionnaires and food guide recommendations

    Time frame: 3 weeks

    Changes on the Food Guide Recommendation

  4. Physical activity level

    Time frame: 3 weeks

    Modification on physical activity level measured by accelerometry
