Adherence to Mediterranean Diet and Diet Quality in Patients with Inflammatory Bowel Disease: A Single-Center, Observational, Case-Control Study.

The nutritional status in inflammatory bowel disease (IBD) is often impaired, and adherence to the Mediterranean diet (MedDiet) remains under-investigated. The aim of this study was to assess diet quality (DQ) and adherence to MedDiet in a cohort of Sardinian IBD patients. We conducted a case-control study in which 50 Crohn's disease (CD) and 50 ulcerative colitis (UC) patients were matched with 100 healthy controls each. The Diet Quality Index (DQI-I) and Medi-Lite were used to assess DQ and adherence to MedDiet, respectively. Subgroup analysis by disease characteristics and use of advanced therapies were also carried out. DQI-I scored significantly lower in IBD, independently of disease localization and behavior (CD) and disease extent (UC): [DQI-I: CD 34.5 (IQR 33-37) vs. CTRL 40 (IQR 38.5-43) p < 0.0001; UC 34.5 (IQR 33-37) vs. CTRL 42 (IQR 40-44) p < 0.0001]. Medi-Lite scores were significantly lower in stricturing and ileo-colonic CD and in extensive UC: [Medi-Lite CD 7.5 (IQR 7-9)] vs. CTRL 9 (IQR 7-10) p = 0.0379]; [UC 8 (IQR7-10) vs. CTRL 9 (IQR 8-10.5) p = 0.0046]. IBD patients had a low DQ independently of disease type and phenotype. Patients with ileo-colonic stenosing CD or extensive UC had lower MedDiet adherence, suggesting that its benefits may be mitigated by low acceptance in specific subgroups.

Quality of diet and odds of metabolic syndrome in Iranian adults: Baseline results from the PERSIAN Kavar cohort study (PKCS).

BACKGROUND AND AIMS: Metabolic Syndrome (MetS) is a major risk factor for cardiovascular diseases and type 2 diabetes mellitus. Diet quality has been associated with multiple chronic diseases. We aimed to investigate the association between the quality of diet and the odds of being diagnosed with MetS. METHODS AND RESULTS: This study was conducted cross-sectionally on baseline data of 2225 individuals from the PERSIAN Kavar Cohort Study (PKCS). The quality of diet was measured based on the Diet Quality Index - International (DQI-I), using Food Frequency Questionnaires. The association between DQI-I and MetS and its components was measured via logistic regression models in crude and adjusted models. We did not observe any association between DQI-I and MetS in the overall population. However, after adjustment for potential confounders, we found that male participants with higher DQI-I scores had a lower risk of MetS [adjusted odds ratio (OR) 95% confidence interval CI) = 0.62 (0.42-0.93)]. Moreover, analogous trends were observed with respect to some components of MetS, including elevated triglyceride (TG) [crude OR (95% CI) = 0.89 (0.70-0.98); adjusted OR = 0.82 (0.65-0.93)], lowered high-density lipoprotein cholesterol (HDL-c) [crude OR (95% CI) = 0.79 (0.57-0.99); adjusted OR = 0.76 (0.55-0.97)], and abnormal glucose homeostasis [crude OR (95% CI) = 0.80 (0.55-0.94); adjusted OR = 0.73 (0.51-0.91)] only in male participants, both before and after adjustment for potential confounders. CONCLUSION: In this study, we showed that higher adherence to a high-quality diet was associated with a lower chance of developing MetS in men. Biological gender might be responsible for the observed discrepancies.

The association between diet quality index-international and inflammatory markers in Iranian overweight and obese women.

Objectives: The present study was conducted to evaluate whether there is a link between the diet quality index (DQI) and markers of systemic inflammation in Iranian overweight and obese women. Methods: This cross-sectional study included 200 Iranian overweight and obese women aged 18-48 years. The DQI-international (DQI-I) comprises four main components: variety, adequacy, moderation, and overall balance. Blood samples were collected in a fasted state to measure inflammatory markers. Results: After adjusting for age, body mass index (BMI), physical activity, total energy intake, economic status, education, supplement intake, age of starting obesity, and history of body mass loss, a marginally significant negative association was observed between the homeostasis model assessment of insulin resistance (HOMA-IR) and the DQI-I (ß: -0.015, 95% CI: -0.03, 0.000; p = 0.061). The results after adjustment showed that DQI-I has a negative association with high-sensitivity C-reactive protein (hs-CRP) concentrations (ß: -0.031, 95% CI: -0.104, -0.031; p = 0.023). Furthermore, negative associations were observed between the adequacy component and levels of HOMA-IR (ß: -0.025, 95% CI: -0.100, 0.047, p = 0.050) and hs-CRP (ß: -0.615, 95% CI: -1.191, -0.020; p = 0.045). In addition, negative associations were found between transforming growth factor-ß (TGF-ß) and balance score (ß: -6.270, 95% CI: -39.211, -3.661, p = 0.020), as well as HOMA-IR (ß: -0.080, 95% CI: -0.202, -0.000, p = 0.041) and chemoattractant protein-1 (MCP-1) (ß: -0.562, 95% CI: -11.414, -0.282, p = 0.021), with the various component. A marginally significant negative association between galectin 3 (Gal-3) and moderation score (ß: -0.451, 95% CI: -1.171, 0.060, p = 0.060) was found. In addition, a marginally significant inverse association was also established between hs-CRP and variety score (ß: -0.311, 95% CI: -0.970, 0.001, p = 0.052). The Receiver Operating characteristic (ROC) curve analysis demonstrated that DQI-I might better predict HOMA-IR with a cut point of 3.13 (AUC = 0.698, 0.511-0.699, p = 0.050). Conclusion: These findings showed that a higher adherence to diet quality and its components could probably be related to lowering the inflammatory markers considerably in overweight and obese women.

Estimation of the Quality of the Diet of Mexican University Students Using DQI-I.

The quality of diet can be measured using diet quality indices, based on knowledge of associations between diet and health. The objective of this work was to evaluate whether the International Diet Quality Index is suitable for use as a diet quality index in populations of Mexican university girls. A cross-sectional nutritional survey was conducted at the University of Chihuahua (Mexico), collecting semi-quantitative nutritional information and socio-economic and lifestyle data from a representative sample of 400 women. Mean (Standard Deviation (SD)) age was 21.43 years (SD: 3.72); 59.1% were normal weight, 26.6% overweight, 15.3% obesity. The Diet Quality Index-International (DQI-I) was developed according to the method of Kim et al. (2003) and focused on major aspects of a high-quality diet (variety, adequacy, moderation and overall balance). The total score of Diet Quality Index-International reached 53.86% (SD: 11.43), indicating that the general diet of Mexican women a poor-quality diet. Adequacy scored highest, followed by moderation and variety. Overall balance scored the lowest. Variety: 26.3 % consumed less than 4 food groups daily, only 12.8% take more than 1 serving from each food group, and 50.6% consumed only one source of protein daily. Regarding adequacy, a large proportion of the population reported an intake of proteins, vitamin C, calcium, iron, and fruit greater than 50% of recommendation; the vegetables, fiber and grain groups were less 50%. Poor scores were obtained for total fat and SFA consumption (moderation). No statistically significant differences are observed for any of the variables under study and score of the Diet Quality Index-International: body mass index, weight, physical activity level, education level of father and mother, location of lunch, breakfast considered important, knowledge of nutrition, which allows us to consider a relatively uniform population in its eating habits. These people are close to a Westernized diet, and an intervention in nutritional education would be advisable to improve the intake of unprocessed foods, consume a greater variety of protein sources and significantly reduce consumption of sugary foods and soft drinks. Due to different methodological and cultural factors, the proposed Diet Quality Index-International dietary assessment method does not seem to be useful in the assessment of diet quality in the Mexican university population, so further research is needed to develop a diet quality index adapted to the Mexican population.

The association between meal-based diet quality index-international (DQI-I) with obesity in adults.

BACKGROUND AND OBJECTIVE: Due to the growing global trend of obesity, it is necessary to study the diet quality as a modifiable factor to reduce the dangerous consequences of obesity. Therefore, the aim of this study was to evaluate the association between meal-based diet quality index-international (DQI-I) with obesity in adults. METHODS: This cross-sectional study was performed on 850 men and women in Tehran (aged 20-59 y). Dietary intakes were assessed using three 24-h dietary recalls. Meal-based Diet quality was assessed based on the construction of DQI-I. The total DQI-I score ranged from 0 to 100, with higher scores denoting better diet quality. Multiple linear regression analysis was used to examine the association of DQI-I and BMI in each meal and Logistic regression analysis was used to examine the association of DQI-I and obesity in each meal. RESULTS: The mean (± SD) of age, body mass index (BMI), waist circumference (WC) and waist to hip ratio (WHR) were 42.35(± 10.90) years, 27.32(± 5.61) kg/m2, 89.09 (± 12.04) cm and 0.86 (± 0.11), respectively. In none of the meals, after adjusting for confounders, no significant difference in BMI was observed in the both women and men groups. After controlling of confounders, there was not any relationship between meal-based DQI-I and BMI resulted from multiple linear regression analysis also there was not any significant association between meal-based DQI-I and obesity resulted from Logistic regression analysis. CONCLUSION: In this study, we did not find any significant association between meal-specified DQI with obesity. To reach the better evaluation, more prospective studies with large sample size are needed.

Certain dietary patterns are associated with GLIM criteria among Chinese community-dwelling older adults: a cross-sectional analysis.

Disease-related malnutrition is prevalent among older adults; therefore, identifying the modifiable risk factors in the diet is essential for the prevention and management of disease-related malnutrition. The present study examined the cross-sectional association between dietary patterns and malnutrition in Chinese community-dwelling older adults aged ≥65 years in Hong Kong. Dietary patterns, including Diet Quality Index International (DQI-I), Dietary Approaches to Stop Hypertension (DASH), the Mediterranean Diet Score, 'vegetable-fruit' pattern, 'snack-drink-milk product' pattern and 'meat-fish' pattern, were estimated and generated from a validated food frequency questionnaire. Malnutrition was classified according to the modified Global Leadership Initiative on Malnutrition (GLIM) criteria based on two phenotypic components (low body mass index and reduced muscle mass) and one aetiologic component (inflammation/disease burden). The association between the tertile or level of adherence of each dietary pattern and modified GLIM criteria was analysed using adjusted binary logistic regression models. Data of 3694 participants were available (49 % men). Malnutrition was present in 397 participants (10⋅7 %). In men, a higher DQI-I score, a higher 'vegetable-fruit' pattern score and a lower 'meat-fish' pattern score were associated with a lower risk of malnutrition. In women, higher adherence to the DASH diet was associated with a lower risk of malnutrition. After the Bonferroni correction, the association remained statistically significant only in men for the DQI-I score. To conclude, a higher DQI-I score was associated with a lower risk of malnutrition in Chinese older men. Nutritional strategies for the prevention and management of malnutrition could potentially be targeted on dietary quality.

Diet Quality: A Neglected Parameter in Children With Food Allergies. A Cross-Sectional Study.

Background-Objective: With recent evidence suggesting that growth is no longer considered a major issue in children with food allergies (FA) on elimination diet, priority has shifted to diet quality to establish healthy eating patterns and prevent non-communicable diseases. The Diet Quality Index - International (DQI-I) could be useful for assessing the overall diet quality of FA-children. This study aimed to evaluate the impact of elimination diet on DQI-I in children with FA and the accuracy of DQI-I in reflecting nutrient intake. Materials-methods: In a prospective, cross-sectional, cohort study of FA-children (2-14 years), nutritional intake was evaluated using a 7-day food frequency questionnaire, 24-h dietary recall, and the DQI-I. Results: Of the 76 children recruited, 44.7% had multiple allergies. Mean overall DQI-I score was 52 points, with only 28% of participants having good overall DQI-I (≥60 points). DQI-I moderation and balance were the most affected domains. Participants with multiple allergies had higher DQI-I moderation and balance and lower vitamin D and Ca intake. Compared to toddlers, schoolchildren had higher DQI-I variety and lower moderation and received higher vitamin B2, vitamin B12, Ca, P, and Zn. The number of allergies, age, and milk avoidance were independently associated with adjusted DQI-I moderation and balance, energy, and certain micronutrient intake. Higher percentages of participants with good DQI-I received adequate amounts of Mn and vitamins A, B6, C, and folate than those with poor DQI-I. Conclusions: In children with FA on elimination diet, the DQI-I accurately captured the deflection of diet quality related to the development of chronic, non-communicable diseases through its moderation and balance components. This is DQI-I's main purpose as a healthy diet indicator and as such it would be a useful tool responding to the needs of the contemporary shifting of priorities in FA-children's diet from quantity to quality. Nevertheless, it does not accurately reflect the intake of certain micronutrients potentially compromised by elimination diets. Therefore, regular nutritional assessment utilizing both the DQI-I and tools assessing individual nutrient intakes along with professional nutrition counseling should be integral parts of the individualized management of children with FA to ensure adequate nutrient intake and establish healthy dietary patterns.

Association between Ag-RP, alpha-MSH and cardiovascular risk factors regarding adherence to diet quality index-international (DQI-I) among obese individuals.

Introduction: Obesity is a strong promoter of cardiometabolic risk factors and is associated with several chronic comorbidities. Recently, the role of α-melanocyte stimulating hormone (α-MSH) and agouti related peptide (Ag-RP) in regulation of energy balance has attracted much attention. In current study, we evaluated the association between α-MSH and Ag-RP with cardiometabolic factors among obese individuals with different adherence to Diet Quality Index-International (DQI-I) values. Methods: In this research, 188 obese adults aged between 20 and 50 years old and body mass index (BMI) between 30 and 40 kg/m2 were recruited. Dietary intakes of participants and DQI-I calculation was performed using a semi-quantitative food frequency questionnaire (FFQ) with 132 food items. Serum glucose, lipids, insulin, and plasma α-MSH and Ag-RP levels were measured using ELISA kits. Homeostasis model assessment for insulin resistance index (HOMA-IR) and quantitative insulin sensitivity check index (QUICKI) were also calculated. Results: Among those with the lowest adherence to DQI-I, Ag-RP was positively associated with systolic blood pressure (SBP) (P = 0.03) among males, which was associated with waist circumference (WC) (P = 0.01) and diastolic blood pressure (DBP) (P = 0.01). Moreover, among males with low and moderate adherence to DQI-I, α-MSH was positively associated with insulin (P = 0.04), weight (P = 0.03), WC (P < 0.01), SDP (P = 0.02) and DBP (P = 0.01). Also, Ag-RP showed a positive association with BMI values (R2 = 0.03; P = 0.03). Conclusion: According to our findings, in obese subjects with poor to moderate adherence to DQI-I, Ag-RP and α-MSH were in positive correlation with cardiometabolic risk factors. These findings further clarify the clinical importance of these parameters as prognostic factors of cardiometabolic abnormalities.

Comparison of diet quality among female students in different majors at Taibah University.

BACKGROUND: Diet quality is a term used to assess both the quality and variety of food intake by comparing dietary guidelines. The quality of dietary intake can be used to determine the association between food intake and health status. Studies comparing diet quality among students from different departments are limited. AIM: The aim of this study was to determine the dietary quality of female college students with majors in different departments at Taibah University, Madinah, Kingdom of Saudi Arabia. METHODS: This study was a cross-sectional study conducted with 658 female participants. The Diet Quality Index-International (DQI-I) was used to describe dietary quality. RESULTS: The total DQI-I score of the College of Applied Medical Sciences (CAMS) students (55.5%) was higher than those of the College of Sciences (CS) (52.3%) and College of Arts and Humanities (CAH) (50.4%) students. The risk of having a poor diet was higher among the CS (odds ratio (OR) = 1.154, 95% confidence interval (CI) (95% CI) = 1.007-1.879) and CAH students (OR = 1.624, CI = 1.012-2.604) than among the CAMS students. Having a low DQI-I score was associated with a high risk of obesity (OR= 2.478, 95% CI = 1.007-3.879) and a high body fat % (OR = 3.920, 95% CI = 1.757-8.749). CONCLUSION: This study showed the need to raise awareness among the younger population about the importance of healthy eating, which involves implementing healthy habits to improve one's quality of life.

Gender inequalities in diet quality and their socioeconomic patterning in a nutrition transition context in the Middle East and North Africa: a cross-sectional study in Tunisia.

BACKGROUND: In a context of nutrition transition and major shifts in lifestyle and diet, the Middle East and North Africa features a marked gender excess adiposity gap detrimental to women. In this setting, where gender issues are especially acute, we investigated gender differences in dietary intake with a focus on diet quality, and how the differences varied with the area of residence and socio-demographic characteristics. METHODS: The study was conducted in 2009-2010 in the Greater Tunis region (Tunisia), as a case study of an advanced nutrition transition context in the region. A cross-sectional survey used a random, stratified, clustered sample of households: 1689 women and 930 men aged 20-49 years were analyzed. Dietary intake was assessed using a 3-day food record. Nutrient content was derived from a specific Tunisian food composition database. We analysed the Diet Quality Index-International (DQI-I) and sub-scores (variety, adequacy, moderation and balance). A score of DQI-I > 60 defined good diet quality. Inequality measures were women vs. men differences in means for interval variables and odds-ratios (OR) for DQI-I > 60. Their variation with socio-demographic characteristics was estimated using models featuring gender x covariate interactions. RESULTS: Mean energy intake/day was 2300 ± 15 kcal for women vs. 2859 ± 32 kcal for men. By 1000 g/kcal/d women consumed more fruits and sweets but less red meat and soft drinks than men. Women had a higher mean moderation sub-score than men (+ 1.8[1.4, 2.2], P < 0.0001) but lower variety (- 2.0[- 2.3, - 1.6], P < 0.0001) and adequacy (- 1.8[- 2.0, - 1.5], P < 0.0001). Thus, the overall mean DQI-I was lower among women than men (58.6 ± 0.3 vs. 60.4 ± 0.3, - 1.8[- 2.6, - 1.0], P < 0.0001) as was the proportion of DQI-I > 60 (45.2% vs. 55.7%, OR = 0.7[0.5, 0.8], P < 0.0001). Adjusted gender differences in DQI-I decreased with age but were higher in larger households and extreme categories of education (no-schooling and university) vs. the middle categories. CONCLUSION: In this nutrition transition context with only average diet quality, it was somewhat lower for women. Socioeconomic patterning of gender contrasts was mild. Beyond, that women had lower adequacy and variety scores but better moderation is a possible pathway for gender specific prevention messages.

Prospective association between adherence to dietary recommendations and incident depressive symptoms in the French NutriNet-Santé cohort.

A posteriori healthier dietary patterns and several nutrients have been associated with lower risks of depression in various studies; however, evidence is lacking with regard to the prospective association between adherence to nutritional recommendations (food-based and nutrient-based recommendations) and incident depression or depressive symptoms. In this study, we investigate such associations in the NutriNet Santé cohort. The study sample included 26 225 participants (aged 18-86 years) who were initially free of depressive symptoms. Adherence to nutritional recommendations was measured by four scores namely modified French Programme National Nutrition Santé-Guideline Score (mPNNS-GS), Alternative Healthy Eating Index-2010 (AHEI-2010), Probability of Adequate Nutrient Intake Dietary Score (PANDiet) and Diet Quality Index-International (DQI-I), using non-consecutive dietary record data during the first 2 years of follow-up (mean number of recording days=8, sd 2). Depressive symptoms were defined by a Center for Epidemiologic Studies Depression Scale (CES-D) score ≥17 for men and ≥23 for women. We used Cox proportional hazards models to estimate hazard ratios and 95 % CI, modelling the dietary scores as standardised continuous variables and as tertiles. Over a mean follow-up of 6 years, we identified 2166 incident cases of depressive symptoms. All dietary scores with the exception of the AHEI-2010 were significantly inversely associated with incident depressive symptoms. In the fully adjusted model, an increase of 1 sd in the mPNNS-GS, PANDiet and DQI-I was, respectively, associated with an 8 % (95 % CI 4, 13), 5 % (95 % CI 1, 9) and 9 % (95 % CI 5, 13) reduction in the risk of depressive symptoms. Overall, these findings suggest that diet in accordance with national or international guidelines could have beneficial effects with regard to mental health.

Differences of Socio-psychology, Eating Behavior, Diet Quality and Quality of Life in South Korean Women according to Their Weight Status.

We aimed at assessing psychological variables and eating behaviors on quality of diet and life in South Korean women according to their weight status. Socio-psychology, eating behavior, quality of diet and quality of life data were assessed in 114 women (mean age: 34.5 ± 8.09 years). NEO Personality Inventory (NEO-PI-RS) and coping styles questionnaire were used to assess socio-psychology variables, and eating behavior was assessed using the Eating Attitudes Test-26 (EAT-26), Dutch Eating Behavior Questionnaire (DEBQ), and General Food Craving Questionnaire Test (G-FCQ-T). Quality of diet was analyzed by Diet Quality Index-international (DQI-I), and obesity-related quality of life was evaluated using the Korean Obesity-related Quality of life Scale (KOQOL). Significant differences were in the psychological variables and eating behaviors in the obese group than the normal and overweight groups (p < 0.05). The overall score of DQI-I was significantly lower in the obese group than that of their counterparts (p < 0.05). BMI was positively correlated with neuroticism, emotional eating, and obesity-related quality of life, and negatively correlated with diet quality. Neuroticism was positively correlated with emotional eating and food craving. Emotional eating was positively correlated with obesity-related quality of life. In conclusion, women with a higher BMI had significantly more problematic eating behaviors, poor diet quality and quality of life.

Dietary scores at midlife and healthy ageing in a French prospective cohort.

Although nutrition has been advocated as a major determinant of healthy ageing (HA), studies investigating the link between dietary quality and HA are scarce. We investigated the association between adherence to French food-based and nutrient-based guidelines at midlife, as assessed by three dietary scores, and HA. HA was assessed in 2007-2009, among 2329 participants of the SUpplémentation en Vitamines et Minéraux AntioXydants study aged 45-60 years at baseline (1994-1995) and initially free of diabetes, CVD and cancer. HA was defined as not developing any major chronic disease, good physical and cognitive functioning, no limitations in instrumental activities of daily living, no depressive symptoms, no health-related limitations in social life, good overall self-perceived health and no function-limiting pain. Data from repeated 24-h dietary records provided at baseline permitted the computation of the modified French Programme National Nutrition Santé-Guideline Score (mPNNS-GS), the Probability of Adequate Nutrient Intake Dietary Score (PANDiet) and the Diet Quality Index-International (DQI-I). Associations of these scores with HA were assessed by logistic regression. In 2007-2009, 42 % of men and 36 % of women met our criteria of HA. After adjustment for potential confounders, higher scores of the mPNNS-GS (ORquartile 4 v. quartile 1 1·44; 95 % CI 1·10, 1·87; P trend=0·006) and the PANDiet (1·28; 95 % CI 1·00, 1·64; P trend=0·03) were associated with higher odds of HA. We observed no association between DQI-I and HA. In conclusion, this study suggests a beneficial long-term role of high adherence to both food-based and nutrient-based French dietary guidelines for a HA process.

Differences of Socio-psychology, Eating Behavior, Diet Quality and Quality of Life in South Korean Women according to Their Weight Status

We aimed at assessing psychological variables and eating behaviors on quality of diet and life in South Korean women according to their weight status. Socio-psychology, eating behavior, quality of diet and quality of life data were assessed in 114 women (mean age: 34.5 ± 8.09 years). NEO Personality Inventory (NEO-PI-RS) and coping styles questionnaire were used to assess socio-psychology variables, and eating behavior was assessed using the Eating Attitudes Test-26 (EAT-26), Dutch Eating Behavior Questionnaire (DEBQ), and General Food Craving Questionnaire Test (G-FCQ-T). Quality of diet was analyzed by Diet Quality Index-international (DQI-I), and obesity-related quality of life was evaluated using the Korean Obesity-related Quality of life Scale (KOQOL). Significant differences were in the psychological variables and eating behaviors in the obese group than the normal and overweight groups (p < 0.05). The overall score of DQI-I was significantly lower in the obese group than that of their counterparts (p < 0.05). BMI was positively correlated with neuroticism, emotional eating, and obesity-related quality of life, and negatively correlated with diet quality. Neuroticism was positively correlated with emotional eating and food craving. Emotional eating was positively correlated with obesity-related quality of life. In conclusion, women with a higher BMI had significantly more problematic eating behaviors, poor diet quality and quality of life.

The Effect of Repeated Nutrition Education on Health Improvement Program by Diet Quality Index-International (DQI-I) Evaluation in Office Workers / 대한지역사회영양학회지

The purpose of this study was to investigate the effect of 3-month nutrition education (First Time Intervention, FI) + additional 3-month nutrition education (Repeated Intervention, RI) which was performed after the 8-month follow-up. FI was conducted during 0-3 months and RI for 11-14 months. Ninety-two subjects completed FI program, and 38 out of 92 subjects who received FI finished the RI. Anthropometric data, dietary assessment (24hr recall) and fasting blood analysis were measured at 0 month, 3 months, 11 months and 14 months time points. After FI (3 mo), waist circumference, triglycerides, total cholesterol were significantly decreased. At 11 month follow-up, body weight, BMI, hip circumference, SBP, DBP were significantly rebounced and HDL cholesterol was significantly decreased. Therefore, the effect of short-term nutrition education was not being sustained. After the secondary nutrition intervention (14 mo), waist circumference and hip circumference were again significantly decreased. Total diet quality index-international (DQI-I) score was significantly increased in both FI group and RI group. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.129, p < 0.05) and counts of nutrition education (r = 0.159, p < 0.05), indicating that effective nutrition education helps improve the diet quality leading to a possible role in CVD prevention among male workers. Although a short-term intervention seems to be a success, the effect was not retained in this study. Therefore, we suggest incorporating nutrition education as a routine program for male worker at worksite.

Evaluation of Diet Quality of Children and Adolescents Based on Nutrient and Food Group Intake and Diet Quality Index-International (DQI-I) / 대한지역사회영양학회지

It is suggested that evaluation of diet quality may be a great indicator of nutritional assessment. The aim of this study was to evaluate the diet quality of children and adolescents based on nutrient and food group intake and Diet Quality Index-International (DQI-I). This survey was conducted through questionnaires and diet record survey to 477 students (elementary school students; n = 131, middle school students; n = 136, and high school students; n = 210). The results showed that high school students were significantly more often to skip breakfast compared with the other groups. The middle and high school students consumed significantly higher intakes of food and energy compared to the elementary school students. Also the number of nutrients in Index of Nutritional Quality (INQ) < 1.0 of high school students were significantly higher than that of elementary and middle school students. The Korean's dietary diversity score (KDDS) of elementary school, middle school and high school students were 4.1, 4.4 and 4.3 respectively. The average DQI-I of elementary school, middle school and high school students were 66.7, 65.5, and 63.7, respectively and there was significant difference. Also, middle school students showed to have higher score in variety and adequacy category compared with the other groups, and elementary school students appeared to have higher score in moderation category. In conclusion, high school students appeared to have unhealthy dietary habits in terms of high frequency of skipping breakfast and lower INQ and DQI-I score compared to the elementary school and middle school students. Therefore, the proper dietary management should be needed for high school students.
