Based on the bio-psycho-social approaches, various studies have recently been carried out on dietary patterns and other health-linked behaviors in patients with psychiatric disorders. The purpose of this study was to investigate dominant dietary patterns in patients with bipolar spectrum disorders due to the great importance of dietary patterns in general health of people.
In this cross-sectional and case-control study, 90 patients, who referred to Nekoei-Hedayati Hospital and diagnosed with bipolar spectrum disorders by psychiatrists, were participated as well as 90 healthy individuals as controls using convenience sampling. The two groups were studied using demographic and food frequency questionnaires. Data were analyzed using factor analysis and independent t-test.
Factor analysis identified three dominant dietary patterns of 1) western dietary patterns, 2) healthy dietary patterns and 3) traditional dietary patterns. Results showed that people with bipolar disorders followed western and traditional dietary patterns, compared to the healthy group (p = 0/000).
Based on the findings, traditional and western dietary were dominant dietary patterns in patients with bipolar disorders. These eating habits might play important roles in health problems of these patients. Further longitudinal studies on the nutrition-health interactions within bipolar patients are suggested.
