Depression can be caused by lifestyle factors in patients with multiple sclerosis, according to research published in BMC Psychiatry.
Modifiable lifestyle factors contribute to depression in multiple sclerosis (MS) patients, according to a study published in BMC Psychiatry.
Researchers from St. Vincent's Hospital Melbourne in Victoria, Australia examined nearly 2,500 MS patients in order to understand the association between lifestyle risk factors, medication, and depression risk through the analysis of self reported data. The researchers collected data about the participants' sociodemographics, diagnostic history, level of disability, comorbidities, fatigue, depression, body mass index (BMI), and an assortment of lifestyle and health behaviors. Patients were mainly female (82.4 percent) and middle aged (median age 45 years) and most patients (61.3 percent) had relapsing remitting MS. Most participants health either a bachelor (36.5 percent) or post graduate degrees (23.5 percent) and worked either full time (32.8 percent) or part time (21.3 percent). Diagnosis occurred at a median age of 37 years and half (45.2 percent) had been recently diagnosed within the last 5 years. Mild disability was reported in 54.8 percent of the patients.
About a fifth of the patients (19.3 percent, 429 patients) screened positive for depression and 21.8 percent were taking prescription medication for depression. However, 10 percent of those taking medication for depression stated they did not have depression. Of patients who screened positive for depression, 92.9 percent also screened for clinically significant fatigue. The patients reported the following symptoms:
The following lifestyle factors were associated with low risks of screening positive for depression:
“This study demonstrates a strong clinically and statistically significant association between modifiable lifestyle factors and risk of depression,” the authors concluded. “Diet, smoking, exercise, omega 3 supplementation - particularly flaxseed oil - fish consumption, social support, vitamin D supplementation, BMI, alcohol intake, meditation and choice of medication are important modifiable factors in depression risk for people with MS. It is important for clinicians and people with MS to be aware of the wide range of modifiable lifestyle factors that may reduce depression risk as part of a comprehensive secondary and tertiary preventive medical approach to managing MS.”
