An interventional study of Educational talk about physical activity and nutritional recommendations before a critical period of fat gain in university students in Obesity, sponsored by Pontificia Universidad Catolica de Valparaiso. Completed at 1 site in Chile. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-07-28.
Sponsored by Pontificia Universidad Catolica de Valparaiso · Not applicable, Interventional, and Prevention
The present study aimed to investigate the effects of a single nutritional preventive session previous to a critical period linked to fat gain in university students with overweight and obesity, emulating a nutritional session of a public health system.
11,522 studies on the registry are indexed under Obesity; 2,033 are open to participants now.
This study's enrollment of 36 is below the median of 67 across 9,006 interventional studies indexed under Obesity.

Exclusion Criteria:
- Presente gastrointestinal problems (vomit or diarrheas) during the three weeks that last the experiment.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Other: Educational talk about physical activity and nutritional recommendations before a critical period of fat gain in university students
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.
Body composition measurements
Changes on fat mass measured by Dual X-ray Absorptiometry (DXA)
Time frame: 3 weeks
Feeding questionnaires and food guide recommendations
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.
Time frame: 3 weeks
Feeding questionnaires and food guide recommendations
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.

Ran from Aug 2017 to primary completion in Sep 2017, 0 months.
Of 3,680 non-industry interventional studies with no phase under Obesity, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 43. This study's 0 months is below that.
Counting every sponsor, half of 3,843 studies reached it within 22 months; a quarter within 10 and three quarters within 42.
