Depression is one of the most common mental disorders worldwide and has been reported as a consequence of stressful work environments including hospitals. The aim of this study was to investigate the relationship between diet quality and depression in Baqiyatallah Al-Azam Hospital staff in Tehran, Iran.

This cross-sectional study was performed with the participation of 100 female staff working in Baqiyatallah Al-Azam Hospital in Tehran with mean age of 37.28 ± 7.98 years and mean body mass index of 26.54±4.27 kg/m2. Depression symptoms were assessed using the Beck Depression Inventory-II questionnaire. Food frequency questionnaire and Healthy Eating Index (HEI) were used to assess the quality of the diet. Nutritionist 4, SPSS software and Pearson correlation coefficient were used for data analysis. The significant level was considered less than 0.05.

The findings of the study revealed that the mean and standard deviation of depression score in the subjects was 11.71±7.7. The mean and standard deviation of HEI index in women under study was 64.5±8.1. The correlation coefficient between diet quality and depression in employees was -0.592, which was significant at the level of 0.01.

The results of the study showed that the quality of diet has a significant and inverse effect on employee depression. Further studies, especially prospective ones, are needed to confirm these findings in military communities.

Dietary acid load affects acid–base homeostasis, which may be associated with overweight and obesity as well as dietary quality index international (DQI-I), mean adequacy ratio (MAR), energy density (ED). This study was done to determine the association between dietary acid load with weight status and dietary quality indices among women. This descriptive-analytic study was randomly performed on 306 women aged 20 to 55years. Dietary acid load was calculated by potential renal acid load (PRAL), net endogenous acid production (NEAP) and dietary acid load (DAL). DQI-I, MAR, ED were estimated for the participants. The probability of obesity (95% CI=0.97-5.50, OR=2.33, P=0.04), as well as abdominal adiposity (95% CI=1.21-4.50, OR=2.4, P=0.005) was significantly increased with tertile of DAL (P<0.05). While even after control of confounder variables, other dietary acid load indices (PRAL and NEAP) showed no significant association between dietary acid load and obesity, overweight or abdominal obesity. Also ,with increasing dietary acid load scores, DQI-I and MAR significantly decreased whereas energy density showed a significant increased across tertile categories of dietary acid load indices (P<0.05). DAL was associated with increased risk of obesity and abdominal obesity. PRAL, NEAP and DAL were good indicators of diet quality indices.

Earlier studies have shown a protective association between adherence to healthy eating guidelines and mental disorders in western nations; however, data in this regard are limited from the understudies region of Middle-East. We aimed to examine the association between adherence to healthy eating guidelines, as measured by AHEI, and prevalence of anxiety and depression in a large sample of Iranian adults.
In this cross-sectional study, data on dietary intakes of 3363 adult participants were collected using a validated dish-based 106-item semi-quantitative Food Frequency Questionnaire (FFQ). Adherence to healthy eating was quantified using AHEI as suggested by earlier publications. The Iranian validated version of Hospital Anxiety and Depression Scale (HADS) was used to assess anxiety and depression in study participants. Data on other covariates were gathered using a pre-tested questionnaire.
Overall, the frequency of anxiety and depression was 15.2% and 30.0%, respectively. After taking potential confounders into account, participants with greater adherence to AHEI had 48% lower odds of depression compared with those in the bottom quartile (OR = 0.52; 95% CI: 0.39-0.70). Those in the highest quartile of AHEI had a 29% lower odds of anxiety, compared with those in the lowest quartile (OR=0.71; 95% CI: 0.54-0.94); however, adjustment for dietary intakes and body mass index attenuated the association (OR = 0.75, 95% CI: 0.52-1.09).
Adherence to healthy eating was inversely associated with a lower chance of depression in Iranian adults. Further studies, especially with prospective design, are required to confirm these associations in Middle-Eastern populations.

One of the most important factors in maintaining and improving children's health is the quality of diet. Given the importance of this issue and that so far the quality of children's diets has not been studied in Mashhad, this study was conducted to assess the quality of children's diets in Mashhad using the Healthy Eating Index (HEI).
The diet of 723 children of 3 to 6 years old was collected by food frequency questionnaire (FFQ). FFQ information was evaluated with Nutritionist 4 software and the quality of children's diets was analyzed by HEI. SPSS software was used for statistical analysis, to examine the normality of data, and for comparison between parts of HEI on three levels, respectively, Kolmogorov-Smirnov and Chi-square test were used.
Overall90.6% of children did not have good quality of diet. However, 75.5% percent of children were receiving recommended amounts of bread and cereals. This diat for food groups of dairy, vegetables, fruits, and meat, was respectively, 73.6, 72.9, 73.7 and 87.6 percent, and 88.3 percent of children were consuming too much fat. This diet was, respectively, 69.9 and 71.8 percent for saturated fat and cholesterol. Only 19.4% of children had good food variety.
Most children's diet quality was less than desirable. Low quality diet of children in the population studied was due to the high consumption of fat, saturated fat and cholesterol, and low variability of diet. Thus, probably, by focusing on these issues, one can improve the quality of children's diets.

The “Dietary Guidelines for Americans Adherence Index (DGAI)” was developed based on the adherence to the dietary recommendations of the Dietary Guidelines for Americans 2005 (DGA-2005) to assess the contribution of dietary patterns to chronic diseases. The objective of this study was to evaluate the association of dietary patterns as measured by the modified DGAI with the prevalence of metabolic syndrome (MetS) and its components in Tehranian adolescents. In this cross-sectional study، 706 adolescents aged 10 to 19 years، participated from the fourth phase of the Tehran Lipid and Glucose Study. Usual dietary intake was assessed using a valid food frequency questionnaire، and the DGAI score was calculated for all participants. MetS was defined according to de Ferranti criteria. The most prevalent risk factor for MetS was high waist circumference (51. 8%). After adjusting for confounding variables، those in the highest quartile category of DGAI had a 36% lower risk of low HDL-C (odds ratio=64%، 95% CI: 0. 41-0. 98 and P for trend=0. 03) and 50% lower risk of hypertension (odds ratio=50%، 95% CI: 0. 25-0. 99 and P for trend=0. 02)، compared with the lowest quartile. Increasing adherence to DGAI showed no significant difference in risk of hypertriglyceridemia، hyperglycemia، high waist circumference، MetS، mean body mass index (BMI) or physical activity scores. In adolescents، increasing adherence to Dietary Guidelines for Americans 2005 (DGA-2005) had only an inverse association with low HDL-C and hypertension، but had no relationship with the risk of MetS and its other components.

The risk factors of cardiovascular disease (CVD) can be tracked from childhood into adult life. Diet quality exerts a great influence on incidence of these risk factors. The aim of the present study, conducted within the framework of the Tehran Lipid and Glucose Study, was to assess the trend of diet quality in relation to the recommendations for prevention of cardiovascular disease during a 6.7 year follow up among children and adolescents. Longitudinal study dietary data for 113 children and adolescents was collected using two 24-hour dietary recalls and a food frequency questionaire during the three study phases of study. Diet quality was compared with dietary recommendations for prevention of cardiovascular disease in children and adolescents(poor, moderate, good diet quality). Trends in diet quality score, were assessed during a 6.7 y of follow up. Mean±SD age of participants was 11.45±4.2. The distribution of subjects in the category of “poor diet quality”increased from 8.8% at the start of the study period to 28.3% and 32.4% in the second and third phases respectively. At the beginning of the study, over 80% of subjects had “moderate quality diet” which decreased to 70% and 65% in the 2nd and 3rd phases respectively. More than 10% of subjects had “good diet quality” which decreased to less than 3% in the 2nd and 3rd phases of the study. A significant decrease was also observed in diet quality of participants in phases 2 and 3 compared to the beginning of the study (p<0.05). Results showed that trend of diet quality of children and adolescent compared to reccomendations for prevention of CVD seem unfavorable.
