Correlation between diet quality and metabolic syndrome

Background: The metabolic syndrome [MetS] is increasing with an alarming rate world wide. Since diet components' studies that focus on MetS have produced largely inconsistent results, assessing the whole diet than single nutrients on health can be more practical. The purpose of this study was to determine the association between diet quality and MetS components

Methods: This cross-sectional study included a total of 152 participants aged 20-55 years recruited from the endocrinology center of Tehran University of medical sciences. Dietary intake assessed by food frequency questionnaire [FFQ] was used to calculate healthy eating index 2010 [HEI-2010]. Body mass index [BMI], weight, height, waist circumference, high density lipoprotein-cholesterol [HDL-c], triglycerides [TG], fasting blood glucose [FBG], and blood pressure were measured

Results: In this study HEI mean score was 55.26. Based on HEI-2010 values, diet quality was good in 0.7% of participants, needed improvement in 55.9%, and was poor in 43.4% of cases. Diet quality [HEI] was significantly and linearly related with systolic and diastolic blood pressure, TG, and BMI [P < 0.05]

Conclusions: According to this study, low diet quality can be related to MetS components

Relation of healthy eating index with body composition parameters in Iranian adult

Background: Obesity as the excessive accumulation of adipose in adipocytes has still remained equivocal. Since diets contain many components to prevent from or promote diseases, assessing effects of the whole diet on health can be more practical. The purpose of this study was to investigate the association between quality of diets through healthy eating index [HEI], and body composition parameters in Iranian adults

Methods: This cross-sectional study included a total of 138 participants in the age range of 20-55 years, who referred to Endocrinology Center of Tehran University of Medical Sciences to receive health care services and fulfilled the eligibility criteria to participate in this study. Food frequency questionnaire [FFQ] was used to calculate HEI scores. Body composition data included: Fat mass [FM], fat free mass [FFM], abdominal fat [AF], muscle mass [MM], and total body water [TBW] that were collected by bioelectrical impedance instrument

Results: In this study the mean HEI score was 55.26. Based on HEI-2010 values, diet quality was good in 0.7% of participants, needed improvement in 55.9%, and was poor in 43.4% of the cases. There were significant linear trends between quality of diets and body composition parameters [P < 0.05]

Conclusion: According to our study poor diet quality can be related to FM and obesity in Iranian adults
