Plain English summary of protocol
Background and study aims
Depression is a common and disabling mental disorder. The number of people with depression is increasing in the developed world, which has been linked to lifestyle. The most common treatments fail to solve all cases, and there is a significant percentage of depressed patients who respond poorly to these treatments. Hygienic and dietary measures have proven effective when used in conjunction with standard treatments. However, this combination has not yet been proven to be effective in routine clinical practice conditions. We are carrying out a study of 300 major depression patients to test the effect of antidepressants combined with structured hygienic and dietary recommendations in primary care.
Who can participate?
Adult patients who have depression, can understand spoken and written Spanish and are able to give written informed consent to take part in the study.
What does the study involve?
The patient will be assigned randomly one of two groups:
a) hygienic-dietary recommendations
b) unspecific hygienic-dietary recommendations (control group)
Depression, quality of life and consumption of health and social services scales will be administered.
What are the possible benefits and risks of participating?
There is no guarantee that patients participating in this study have a benefit. We hope that one of the two groups have better outcomes in terms of depressive symptoms than the other, but there are no expected side effects or safety issues.
Where is the study run from?
From three research centers of three Spanish cities:
Universitat Illes Balears in Palma de Mallorca
Grupo Aragonés de Investigación en Salud Mental in Zaragoza
Parc Sanitari Sant Joan de Deu in Barcelona
When is study starting and how long is it expected to run for?
Recruitment will begin in September 2012 and data collection is expected to end in December 2013
Who is funding the study?
Instituto de Salud Carlos III (Spanish Government)

| Scientific title | Hygienic-dietary treatment of Depression in Primary Care: a randomised study |
| Study acronym | HDPC |
| Study objectives | Depressed patients who follow hygienic-dietary recommendations will experience an improvement in their clinical course compared with a control group |
| Ethics approval(s) | Research and clinical trials ethics committee of the Balearic Islands (CEIC), December 2011, ref: 1563-11 IB-PI |
| Health condition(s) or problem(s) studied | Major Depression |
| Intervention | Patients assigned to the active treatment group received an envelope containing a sheet of paper with the four hygienic-dietary recommendations under consideration. 1. Go to bed when sleepy and not before 11 pm. Use your bed and bedroom only for sleep and sex (do not read, watch TV or lie on the bed during the day). If you do not fall asleep after 15 or 20 minutes get up and start an activity until you feel sleepy enough to go back to bed. Get up early, never later than 9 a.m., no matter how well you have slept the night before. Do not lie down or take a nap during the day. 2. Walk at least 1 hour a day, at a good pace but without becoming short of breath or being unable to talk while walking. If you think you have a medical problem which makes walking difficult or uncomfortable consult your doctor. Use appropriate footwear for walking and have a shower or a bath afterwards. 3. Be exposed to environmental light at least 2 hours per day, taking precautions to avoid sunburn or sunstroke (sunscreen, hat, etc.). 4. Try to eat a healthy and balanced diet. Eat at regular hours without snacking between meals. Avoid especially sweet or sugary drinks. Eat fish at least three times per week, plus fruit, cereals, nuts and vegetables daily. The control group received an identical envelope, but in this case with unspecified recommendations: 1. Sleep the hours that you feel your body needs. 2. Adapt the pace of daily physical activity to meet your needs best. 3. If exposed to environmental light take precautions to avoid sunburn or sunstroke (sunscreen, hat, etc.). 4. Try to eat a healthy and balanced diet. |
