We searched all published English studies to identify related articles in MEDLINE, EMBASE, and Google Scholar databases up to December 2015. Therefore, we aimed to conduct the present study to summarize the available data regarding the association of a posteriori dietary patterns and central obesity in adults to test the hypothesis of whether a highly healthy dietary pattern is associated with decreased risk of central obesity. However, findings of studies are inconclusive. In contrast, the adherence to the “Western dietary pattern” was associated with reduced MMI (p = 0.02).Īdherence to healthy dietary pattern might be associated with better muscle strength and greater adherence to Western pattern appears to reduce MMI.Ĭentral obesity is a pivotal component of metabolic syndrome, and several studies have investigated the association of dietary patterns and central obesity. Moreover, we found that those who were in the third tertile of “mixed dietary pattern” compared to those at the first tertile had no significant relationship with muscle strength (p = 0.42) and MMI (p = 0.36) even after controlling for potential confounders.
These factors were labeled as healthy, mixed and western dietary patterns.Īfter control for potential confounders, there were a positive trend between tertiles of “healthy dietary pattern” and muscle strength (p = 0.03). Factor analysis was conducted, and as a result, 3 factors were extracted. Dietary intake was assessed using a 168-item validated food frequency questionnaire. MMI was calculated by total fat free mass (FFM) (kg)/height 2 (m). Socio-demographic data, body composition and muscle strength were determined. We hypothesized that unhealthy dietary patterns are associated with reduced muscle mass and muscle strength.Īnd methods: The present cross-sectional study recruited 270 adults (118 males and 152 females) aged between 18 and 75 years' old.
Dietary patterns may affect muscle mass, strength, and function hence, we evaluated the association of major dietary patterns in relation to muscle mass index (MMI) and muscle strength in middle-aged adults.
