title: Dietary Patterns and Chronic Obstructive Pulmonary Disease: A Meta-analysis.
abstract: Investigation of the relationship between dietary patterns and some chronic noncommunicable diseases has become appealing in nutritional epidemiology. Some studies have reported potential associations between dietary patterns and the risk of chronic obstructive pulmonary disease; however, the results remain conflicting. Thus, we conducted this meta-analysis to pool the results of studies to clarify the associations between dietary patterns and the risk of chronic obstructive pulmonary disease. A literature search of MEDLINE and EBSCO databases was performed to identify relevant studies published from January 1990 up to June 2015. A total of 13 studies met the inclusion criteria and were included in this meta-analysis. The highest category of healthy/prudent dietary patterns when compared with the lowest category was apparently associated with a decreased risk (OR = 0.55; CI: 0.46, 0.66; P < 0.0001). An increase in the risk of chronic obstructive pulmonary disease was shown for the highest compared with the lowest categories of "unhealthy/western-style" dietary patterns (OR = 2.12; CI: 1.64, 2.74; P < (0.0001). The results of this meta-analysis indicate that different dietary pattern may be associated with the risk of chronic obstructive pulmonary disease.
