Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary objective of this study is to evaluate the efficacy of a daily intake of 300mg Lactium over a period of 4 weeks on subjectively perceived stress during an acute stressful situation as compared to a control product. Efficacy is defined as a lower increase in the Visual Analog Scale Stress of the test group in response to the Trier Social Stress Test as compared to the control group. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary objectives of this study are to evaluate the efficacy of a daily intake of 300mg Lactium over a period of 4 weeks as compared to a control product on - chronic stress levels as measured by the stress subscale of the Depression-Anxiety-Stress-Scales, assessed on visits 2, 3 and 4; efficacy is defined as a decrease in stress scores; - the dynamic of the post awakening cortisol secretion measured by the area under the curve with respect to the increase (AUCi), measured on two workdays before visit 2 and two workdays before visit 4; efficacy is defined as a decrease in the AUCi - anxiety as measured by the Visual Analog Scale (VAS) Anxiety during an acute stressful situation, measured on visit 4 before, during and after the Trier Social Stress Test (TSST); efficacy is defined as a lower increase in the VAS anxiety scale in response to the TSST - insecurity as measured by the VAS insecurity scale during an acute stressful situation, measured on visit 4 before, during and after the TSST; efficacy is defined as a lower increase in the VAS insecurity scale in response to the TSST - stress as measured by the VAS stress scale over visits, assessed on visits 2, 3 and 4; efficacy is defined as a decrease in the VAS stress scale - salivary cortisol during an acute stressful situation, assessed on visit 4 2 minutes before and 1, 10, 20, 30 and 45 minutes after the TSST; efficacy is defined as a lower increase in cortisol raw values in response to the TSST - Heart Rate during an acute stressful situation, assessed on visit 4 continuously starting 20 minutes before TSST and ending 20 minutes after TSST; efficacy is defined as a lower increase in HR in response to the TSST - Blood pressure during an acute stressful situation, assessed on visit 4 every 5 minutes starting 20 minutes before the TSST and ending 5 minutes after the TSST; efficacy is defined as a lower increase in blood pressure in response to the TSST - state anxiety as measured by the State-Trait-Anxiety-Inven | — |
