Depression, Anxiety, Dietary Behavior, Sleep, Stress
Conditions
Brief summary
The aim of this cross-sectional online study is to investigate the association between regular feeding behavior and stress, sleep as well as anxiety and depressive symptoms in healthy subjects.
Detailed description
The gut-microbiota-brain (GMB) axis has a multidirectional communication between the intestine, the microbiota, and the central nervous system (CNS). Over the past decade, there has been extensive research showing that the GMB axis has a profound influence not only on neurological disorders but also on neural development, activation of the neuroendocrine axis and neurotransmission, as well as modulation of complex human behaviors. Thus, the GBM-axis is involved in the regulation of stress, emotions, behaviour, and higher cognitive functions. As the GMB plays an essential role in human psychological functioning and mental health, the dietary manipulation of the microbiome may have direct effects on mental well-being, sleep, anxiety and depressive symptoms.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mental well-being and quality of life | At baseline | Subjective life-quality will be measured with the short version of the World Health Organization Quality of Life questionnaire (WHOQOL-BREF,). The WHOQOL-BREF is a self-administered questionnaire comprising 26 questions on the individual's perceptions of their health and well-being over the previous two weeks. Responses to questions are on a 1-5 Likert scale where 1 represents disagree or not at all and 5 represents completely agree or extremely. For the present study only the three subscales (physical and psychological health, and social relationships) will be assessed. |
| General Psychopathology | At baseline | Brief Symptom Checklist (BSCL former BSI), including various subscales such as depression, anxiety |
| Sleep | At baseline | Sleep quality is assessed with the Pittsburgh Sleep Quality Index (PSQI). Each of the sleep components yields a score ranging from 0 to 3, with 3 indicating the greatest dysfunction. The sleep component scores are summed to yield a total score ranging from 0 to 21 with the higher total score (referred to as global score) indicating worse sleep quality. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Stress and Coping | At baseline | Stress will be assessed with the Stress and Coping Inventory (SCI).The SCI is used to determine the current stress load and stress symptoms and to illustrate how to deal with stress using five coping strategies. It comprises 10 scales with 54 items: (A) Current stress load (1) Stress due to uncertainty, (2) Stress due to overload, (3) Stress due to loss and actual negative events, (4) Total stress: Total stress due to insecurity, threat, overload or loss in important areas of life, (5) Physical and psychological stress symptoms; (B) Stress coping (Coping) (1) Positive thinking, (2) Active stress coping, (3) Social support, (4) Keeping faith, (5) Increased alcohol and cigarette consumption. |
