Clinical Trial Summary

Randomized, controlled, double-blind intervention study, with four parallel branches depending on the product consumed, to analyze the efficacy of different types of milks on the improvement of sleep quality.

Description:

The duration of the study will be 90 days (12 weeks). Each day they will have to consume the product under investigation. The subjects who meet the selection criteria will be randomly distributed in each of the study groups (A, B, C or D, depending on the group in which they have been randomized). Each day the subjects will have to fill in a diary on sleep quality and concomitant medication. They will make a total of two visits to the research laboratory and the tests preestablished in the protocol will be performed. Subsequently, a statistical analysis will be performed with the variables measured in the study to obtain the results.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Variation in sleep quality from baseline at 12 weeks.	Visual analog scale from 0 to 10. The higher the value, the more quality.	The evolution of sleep quality after consumption during 12 weeks will be measured.
Secondary	Change in Sleep Quality from baseline at 12 weeks	Visual analog scale from 0 to 10. The higher the value, the more quality.	Sleep quality will be measured with a daily scale, from baseline to 12 weeks.
Secondary	Sleep quality	Measured by Pittsburgh test	It will be measured twice, once at baseline or at the end of the study after 12 weeks of use
Secondary	Insomnia severity	Measured by Insomnia severity index - ISI test	It will be measured twice, once at baseline or at the end of the study after 12 weeks of use
Secondary	Sleepiness	Measured by Epworth test	It will be measured twice, once at baseline or at the end of the study after 12 weeks of use
Secondary	Matutinity - Verpertinity	Measured by Matutinity - Verpertinity questionnaire	It will be measured twice, once at baseline or at the end of the study after 12 weeks of use
Secondary	Anxiety questionnaire	Test STAI, to measure the level of anxiety of the subjects	Day 1, at 12 weeks later
Secondary	Body composition	It is a control variable. Measured by bioimpedance	The test will be measured at baseline and after 12 weeks of consumption.
Secondary	Adverse events	It will be evaluated at each of the visits.	At 12 weeks after consumption
