The association between diet quality index-international and dietary diversity score with preeclampsia: a case–control study

BackgroundPreeclampsia is a significant complication that occurs during the second half of pregnancy. Recent studies have indicated that dietary factors play a crucial role in the development of preeclampsia. The Diet Quality Index-International (DQI-I) and Dietary Diversity Score (DDS) are appropriate indices for assessing the quality of foods, meals, and diets. This study aimed to investigate the relationship between DQI-I, DDS, and preeclampsia.MethodsThis study utilized a case-control design. A total of 90 newly diagnosed preeclampsia cases and 90 healthy controls were included from a referral hospital in Tabriz, Iran. DQI-I and DDS were calculated based on information obtained from a reliable Food Frequency Questionnaire consisting of 168 food items, which assessed participants’ usual diet. Logistic regression analysis adjusted for age, body mass index, education, family history of preeclampsia, and total energy intake was used to estimate odds ratios (ORs).ResultsThe mean age and pre-pregnancy body mass index of the participants were: 27.14 ± 4.40 years and 26.09 ± 3.33 kg/m2, respectively. After adjusting for various confounders, we found significant inverse association between the risk of developing preeclampsia and both DQI-I and DDS. The highest quartile of DQI-I had a significantly lower risk of developing preeclampsia compared to the first quartile (OR = 0.02, 95% CI [0.005, 0.08]) (P < 0.001). Similarly, the highest quartile of DDS had a significantly lower risk of developing preeclampsia compared to the first quartile (OR = 0.09, 95% CI [0.03, 0.31]) (P = 0.001).ConclusionsOur findings suggest that maintaining a high-quality and diverse diet is associated with a lower risk of preeclampsia. Further studies are needed to confirm these associations and explore potential causal relationships.

Diet Quality and Mortality among Chinese Adults: Findings from the China Health and Nutrition Survey.

The association between diet quality and all-cause mortality in Chinese population is unclear. We aimed to study the associations of three a priori diet quality indices-including the Diet Quality Index-International (DQI-I), Chinese Healthy Eating Index (CHEI), and energy-adjusted Dietary Inflammatory Index (E-DII)-and their included components with all-cause mortality. We used baseline data from the 2004, 2006, 2009, and 2011 waves of the China Health and Nutrition Survey (CHNS). We used a multivariable-adjusted Cox model to examine the associations between DQI-I, CHEI, and E-DII with all-cause mortality. During a mean of 7 years of follow-up, a total of 461 deaths occurred among 12,914 participants. For DQI-I, there were significant inverse associations with mortality for the variety score (HRQ4 vs. Q1 = 0.69, 95%CI = 0.52-0.92) and overall balance score (HR>0 vs. 0 = 0.81, 95%CI = 0.66-0.91). The adequacy score of CHEI was associated with 40% less risk of all-cause mortality (HRQ4 vs. Q1 = 0.60, 95%CI = 0.43-0.84). E-DII was not associated with mortality. An estimated 20.1%, 13.9%, and 31.3% of total mortality would be averted if the DQI-I variety score, DQI-I overall balance score, and CHEI adequacy score improved from the bottom to the top quartile, respectively. Improving diet quality, especially improving diet variety and adequacy, and having a more balanced diet may reduce all-cause mortality in Chinese adults.

International diet quality index and revised diet quality index relationship with non-alcoholic fatty liver disease: a case-control study

Background/objectivesRecent studies show the potential role of dietary quality and quantity in predicting the risk of chronic diseases, such as liver disease, therefore, in the present study, we aimed to assess the association of diet quality index International (DQI-I) and diet quality index revised (DQI-R) and their main components with the odds of non-alcoholic fatty liver disease (NAFLD) in adult populations.MethodsThe current case-control study was conducted on 225 patients with NAFLD and 450 controls. Dietary intake was assessed using a validated 168-item food frequency questionnaire, and DQI-I and DQI-R were calculated in participants. Multi-variable logistic regression was used to examine the association of DQI-I and DQI-R and their components with the odds of NAFLD.ResultsThe mean (SD) age and BMI of participants (53% men) were 38.1 (8.8) years and 26.8 (4.3) kg/m2, respectively. In the final model, each one SD increment in the DQI-I score was associated with decreased odds of NAFLD (OR = 0.63; 95%CI = 0.40–0.98) (P = 0.040). Also, of DQI-I components, high adequacy score was related to lower odds of NAFLD (OR = 0.16; 95%CI = 0.06–0.40) (P < 0.001). Also, our findings showed that participants in the highest tertile of DQI-R score had lower odds of NAFLD compared to the lowest tertile of DQI-R (OR = 0.24; 95%CI = 0.10–0.53) (P < 0.001). Furthermore, of DQI-R components, high moderation score are linked to a lower risk of NAFLD (OR = 0.17;95%CI = 0.07–0.43) (P < 0.001).ConclusionOur findings suggested that greater adherence to diet with a higher score of DQI-I and DQI-R may be associated with lower odds of NAFLD.

The association between Diet Quality Index-International score and risk of diminished ovarian reserve: a case-control study.

Although limited evidence exists on the beneficial reproductive effects of diet quality indices, the association is still largely unknown. We aimed to investigate the association between Diet Quality Index-International (DQI-I) and antral follicle count (AFC) and serum antimullerian hormone (AMH) as precise and sensitive markers of ovarian reserve and to assess the risk of diminished ovarian reserve (DOR) in women seeking fertility treatments. In a case-control study, 370 women (120 women with DOR and 250 women with normal ovarian reserve as controls), matched by age and body mass index (BMI), were recruited. Dietary intake was obtained using a validated 80-item semi-quantitative food frequency questionnaire (FFQ). The quality of diets was assessed using DQI-I, which included four major dietary components: variety (0-20 points), adequacy (0-40 points), moderation (0-30 points), and overall balance (0-10 points). DQI-I score was categorized by quartiles based on the distribution of controls. AFC, serum AMH and anthropometric indices were measured. Logistic regression models were used to estimate multivariable odds ratio (OR) of DOR across quartiles of DQI-I score. Increased adherence to DQI-I was associated with higher AFC in women with DOR. After adjusting for potential confounders, the odds of DOR decreased with increasing DQI-I score (0.39; 95% CI: 0.18-0.86). Greater adherence to DQI-I, as a food and nutrient-based quality index, may decrease the risk of DOR and improve the ovarian reserve in women already diagnosed with DOR. Our findings, though, need to be verified through prospective studies and clinical trials.

Sociodemographic and Health Indicators of Diet Quality in Pre-Frail Older Adults in New Zealand.

We collected detailed dietary intake from pre-frail (FRAIL scale 1-2) older adults using NZ Intake24, an online version of 24 h multiple pass dietary recall. Diet quality was ascertained with the Diet Quality Index-International (DQI-I). We used regression generalized linear models to determine predictors of diet quality as well as classification and regression tree (CART) analysis to examine the complex relationships between predictors and identified profiles of sub-groups of older adults that predict diet quality. The median age in this sample (n = 468) was 80.0 years (77.0-84.0). Living with others, a high deprivation index and a higher BMI were independent predictors of poorer diet quality. With CART analysis, we found that those with a BMI > 29 kg/m2, living with others and younger than 80 years were likely to have a lower diet quality. We found that BMI, living arrangement and socioeconomic status were independent predictors of diet quality in pre-frail older adults, with BMI being the most important variable in this sample when the interaction of these variables was considered. Future research is needed to determine the similarities and/or differences in the profile of subgroups of older adults with poorer diet quality.

Nutritional Status and Physical Activity Level of White-Collar Workers: An Island Example

The conducted study aimed to determine the nutritional status and activity level of white-collar workers. &#x0D; 211 volunteers' demographic information, anthropometric measurements, and 3-day food recording were determined. The scales “Diet Quality Index-International (DQI-I)”, “Healthy Eating Index-2015 (HEI-2015)”, and “Dietary Approaches to Prevent Hypertension (DASH)” were used to determine the quality of the diets. The International Physical Activity Questionnaire-Short Form (IPAQ) was used to calculate the activity level of the participants.&#x0D; The average age of participants were 35.70 ± 9.36, while 70.6% were women. The average diet quality scores for DQI-I, HEI-2015, and DASH were 47.8 ± 9.79, 56.40±14.04, and, 2.70 ±1.29 respectively. The IPAQ average score was calculated as 851.44±1065.01 MET. The IPAQ results showed that only 13.3% of participants had sufficient activity levels. The physical activity level of the men was found to be significantly higher than that of the women (p

Dietary quality index and the risk of breast cancer: a case-control study

BackgroundDiet quality is a significant determinant in the etiology of breast cancer (BrCa), but further studies are required to explore this relationship. Therefore, we tried to assess if diet quality, assessed using the Diet Quality Index-International (DQI-I), was related to BrCa among the Iranian population.MethodsIn the present case-control research, 134 women with a recent diagnosis of BrCa and 267 without BrCa were selected as case and control groups. Individual food intake data from a food frequency questionnaire was used to compute DQI-I. Also, the multivariable logistic regression models were utilized to evaluate the association between DQI-I and BrCa odds .ResultsWe found a significant association between the last tertile of DQI-I and BrCa odds in the fully adjusted model (odds ratio (OR) = 0.30; 95% confidence interval (CI): 0.15–0.56). The subgroup analysis based on menopausal status also showed a significant decrease in BrCa odds in pre-and post-menopausal women (pre-menopausal: OR = 0.27; 95% CI: 0.10–0.70 – post-menopausal status: OR = 0.35; 95% CI: 0.13–0.92).ConclusionsOur findings indicated that a higher DQI-I score was related to a lower chance of BrCa. According to our research, a healthy diet pattern is crucial for BrCa prevention.

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

Background and aimsMetabolic 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 resultsThis 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. ConclusionIn 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.

Food insecurity, body mass index, socio-economic status, and food intake in lactating and non-lactating mothers with children under two years

Backgroundfood insecurity (FI) is considered as an essential public health problem which may have detrimental effects on people’s health. The aim of present study was to evaluate FI, body mass index, quantity and quality of food intake in lactating and non-lactating mothers with children under two years.Methodsin this cross-sectional study 307 mothers (237 lactating and 70 non-lactating) were participated. Socio-economic and demographic information were gathered by questionnaires. FI of families was evaluated by the questionnaire of the United States Department of Agriculture (USDA) Household Food Security. For assessing quality and quantity of food intake of mothers, dietary diversity score (DDS), diet quality index-international (DQI-I) and nutrient adequacy ratio (NAR) were calculated. Weight and height of participants were measured and body mass index (BMI) was calculated. Finally, Chi-squared test, analysis of variance (ANOVA) and linear regression were used for statistical analysis.Resultsin this study the rate of underweight, normal weight, overweight, and obesity in mothers was 0.3%, 39.2%, 42.3%, and 18.2%, respectively. Among the determinants of BMI, household food security status had the greatest effect (Beta=-1.584, P < 0.001) and mother age had the least effect (Beta = 0.101, P = 0.013). Mother’s occupational and educational status, having facilities, physiological status of mother, and house size had significant correlation with NAR. Mother’s occupational and educational status, and having facilities had significant relationship with DDS, too. Also, the significant correlation of Mother’s education, having facilities, and physiological status of mother with DQI-I were found.Conclusionswe found that Household food security status had the most effect on BMI of mothers. In this study, the best nutrient adequacy and dietary diversity were found in the obese group and the most diet quality was found in the normal weight group.

Association of diet quality indices with serum and metabolic biomarkers in participants of the ORISCAV-LUX-2 study

PurposeDiet quality is a critical modifiable factor related to health, including the risk of cardiometabolic complications. Rather than assessing the intake of individual food items, it is more meaningful to examine overall dietary patterns. This study investigated the adherence to common dietary indices and their association with serum/metabolic parameters of disease risk.MethodsDietary intakes of the general adult population (n = 1404, 25–79 years) were assessed by a validated food-frequency questionnaire (174 items). The French ANSES-Ciqual food composition database was used to compute nutrient intakes. Seven indicators were calculated to investigate participants’ diet quality: the Alternative Healthy Eating Index (AHEI), Dietary Approaches to Stop Hypertension Score (DASH-S), Mediterranean Diet Score (MDS), Diet Quality Index-International (DQI-I), Dietary Inflammatory Index (DII), Dietary Antioxidant Index (DAI), and Naturally Nutrient-Rich Score (NNRS). Various serum/metabolic parameters were used in the validity and association analyses, including markers of inflammation, blood glucose, and blood lipid status.ResultsFollowing linear regression models adjusted for confounders, the DASH-S was significantly associated with most metabolic parameters (14, e.g., inversely with blood pressure, triglycerides, urinary sodium, uric acid, and positively with serum vitamin D), followed by the DQI-I (13, e.g., total cholesterol, apo-A/B, uric acid, and blood pressure) and the AHEI (11, e.g., apo-A, uric acid, serum vitamin D, diastolic blood pressure and vascular age).ConclusionFood-group-based indices, including DASH-S, DQI-I, and AHEI, were good predictors for serum/metabolic parameters, while nutrient-based indices, such as the DAI or NNRS, were less related to biological markers and, thus, less suitable to reflect diet quality in a general population.

The relationship between diet quality indices and odds of breast cancer in women: a case–control study

Dietary quality is an important factor in the etiology of breast cancer (BrCa), but further studies are required to better elucidate this relationship. Accordingly, we sought to analyze if diet quality, assessed using the Diet Quality Index-International (DQI-I), Mean Adequacy Ratio (MAR), and Dietary Energy Density (DED), was related to BrCa. In this Hospital-based case–control study, 253 patients with BrCa and 267 non BrCa controls were enrolled. Individual food consumption data from a food frequency questionnaire was used to calculate the Diet Quality Indices (DQI). Employing a case–control design, odds ratios (ORs) and 95% confidence intervals (CIs) were obtained, and a dose–response analysis investigated. After adjusting for potential confounders, those in the highest quartile of the MAR index had significantly lower odds of BrCa than those in the lowest (OR = 0.42, 95% CI 0.23–0.78; P for trend = 0.007). Although there was no association between individual quartiles of the DQI-I and BrCa, there was evidence of a significant trend across all the quartile categories (P for trend = 0.030).There was no significant association was found between DED index and the odds of BrCa in the crude and fully adjusted models. We found that higher MAR indices were associated with decreased odds of BrCa, Therefore, the dietary patterns reflected by these scores may serve as a possible guide to preventing BrCa in Iranian women.

Abstract P134: Dietary Intake and Vascular Function and Myocardial Structure in Canadian Youth With and Without Type 1 Diabetes: The Cardea Study

Introduction: People living with T1D are disproportionally more affected by CVD than the general population. As emerging evidence points to direct effects of diet on vascular function and cardiac structure, dietary interventions may be effective strategies to mitigate CVD risk early on. Hypothesis: We tested the hypothesis that specific dietary components and diet quality are associated with early markers of vascular and cardiac structure and function in youth with T1D. We compared these to associations in healthy controls. Methods: Cross-sectional study of 100 youth with T1D aged 14-18 yrs recruited at the Diabetes Clinic at Sainte-Justine Hospital University Center (Montreal, Canada) and 97 age and sex-matched healthy controls. Pulse-wave velocity (PWV) estimated arterial stiffness; velocity time integral (VTI) and acceleration during a flow-mediated dilation test assessed endothelial function. We measured left ventricular mass/height (LVMH), papillary mass, and wall thickness with cardiac MRI. Diet was measured with 3 x 24-h dietary recalls. Nutrients and foods were analyzed with the CANDAT software based on the Canadian Nutrient File. We assessed daily consumption of fruits, vegetables, fish, red meat, sugar-sweetened beverages and juices (SBJs), and sweets and chips. Food groups were all adjusted for total energy intake. We used the Diet Quality Index-International (DQI-I) to assess overall diet quality. We estimated linear regression models for each diet variable/outcome combination separately in youth with T1D and healthy controls adjusting for age, sex, ethnicity, parental education, physical activity and sedentary time (by accelerometer), and heart rate. Results: Girls comprised 48% of the sample; the mean age was 16.3 yrs (SD=1.3). The T1D group included more youth having overweight or obesity (43% vs. 20%), and was more ethnically diverse (White: 60% vs. 72%), compared to controls. Average glycated hemoglobin was 8.5% (SD=1.4) and median diabetes duration 6 yrs (IQR=3-10) in youth with T1D. In youth with T1D : Consuming more fruits was associated with lower PWV (beta [95% CI] per serving: -0.21 [-0.40; -0.02] m/s). Greater SBJ intake was paradoxically associated with higher VTI (per % total energy intake: 0.34 [0.04; 0.65] cm). DQI-I was related to a higher LVMH (per unit: 0.5 [0.1; 0.9] g/m). In controls : Eating more fruit was associated with a greater LVMH (per serving: 2.5 [0.1; 4.7] g/m). Higher SBJ intake was associated with a lower wall thickness (per % total energy intake: -0.10 [-0.20; -0.01] mm). Conclusions: Findings suggest that consuming more fruit could prevent arterial stiffening in youth with T1D. We previously reported that youth with T1D had lower LVMH than controls, and findings herein suggest that better diet quality could help compensate for this deficit. Overall, our results provide evidence on diet as a potential strategy to lower CVD risk in youth with T1D.

Cross-Sectional Analysis of Family Factors Associated with Lifestyle Habits in a Sample of Italian Primary School Children: The I-MOVE Project

The acquisition of healthy dietary and exercise habits during childhood is essential for maintaining these behaviors during adulthood. In early childhood, parents have a profound influence on a child's lifestyle pursuits, serving as both role models and decision-makers. The present study examines family factors as potential contributors to healthy lifestyle habits and their child's overall diet quality among a sample of primary school children. A secondary aim is to evaluate several aspects of diet quality using the Mediterranean adaptation of the Diet Quality Index-International (DQI-I). This cross-sectional study involved 106 children enrolled in a primary school located in Imola, Italy. Data were collected from October to December 2019 using an interactive tool used to assess parent characteristics, children's lifestyle, food frequency (ZOOM-8 questionnaire), and actigraph accelerometers to capture children's physical activity and sedentary behavior. Adherence to the Mediterranean Diet (expressed by KIDMED Index) was positively associated with fathers' educational level, parental sport participation, and the parent's overall nutritional knowledge. Higher mothers' educational level was inversely associated with children's leisure screen time. Parents' nutritional knowledge was positively related to children's average daily minutes of organized sport activities. The better score for DQI-I was for consumption adequacy, followed by variety and moderation. The lowest score was for overall balance. The present study reinforces the importance of family factors in young children's lifestyle choices, particularly their dietary, leisure time, and exercise habits.

The integrative panel of fatty acid desaturase-2 (FADS2) rs174583 gene polymorphism and dietary indices (DQI-I and HEI) affects cardiovascular risk factors among obese individuals

BackgroundRecent studies have shown that dietary intakes and gene variants have a critical role in the obesity related comorbidities. This study aimed to evaluate the effects of the interactions between Fatty acid desaturase 2 (FADS2) gene rs174583 polymorphism and two dietary indices on cardiometabolic risk factors.MethodsThis cross-sectional study was carried out on 347 obese adults aged 20-50 years old in Tabriz, Iran. Healthy eating index (HEI) and Diet quality index-international (DQI-I) were evaluated by a validated semi-quantitative 147-item Food frequency questionnaire (FFQ). Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to determine FADS2 gene variants. Multivariate analysis of covariance (MANCOVA) was used to identify gene-diet interactions on metabolic parameters.ResultsWaist circumference (WC) and serum triglyceride (TG) levels were significantly higher among carriers of TT genotype of FADS2 gene (P < 0.05). In addition, the interactions between FADS2 gene rs174583 polymorphism and DQI-I had significant effects on weight (P interaction = 0.01), fat mass (P interaction = 0.04), fat free mass (P interaction = 0.03), and Body mass index (BMI) (P interaction = 0.02); the highest level of these parameters belonged to TT carriers. Similarly, the interactions between FADS2 gene variants and HEI had significant effects on insulin (P interaction < 0.001), Homeostasis model assessment of insulin resistance (HOMA-IR) (P interaction < 0.001), Quantitative insulin check index (QUICKI) (P interaction = 0.001), and alpha Melanocyte stimulating hormone (α-MSH) (P interaction = 0.03).ConclusionIn this study, for the first time, we reported the effects of gene-diet interactions on metabolic traits. Compliance with dietary indices (DQI-I and HEI) ameliorated the adverse effects of gene variants on metabolic risk factors, especially in heterogeneous genotypes. Further prospective cohort studies are needed to confirm these results.

P258 The association between dietary quality and disease severity in Korean young adult patients with Crohn’s disease: A pilot study

Abstract Background Although associations between various single nutrients and exacerbation of inflammatory bowel disease (IBD) have been reported, more recent attention has focused on overall dietary patterns and quality rather than a single nutrient. This study was to investigate the association of dietary inflammatory potential and dietary quality with disease severity in young adult Crohn’s disease (CD) patients. Methods Non-consecutive 3-day food records were investigated in 25 patients with CD aged 19-40 years. Patients with moderate or severe active disease were excluded to investigate their usual dietary habits. A survey on dietary behavior was conducted and clinical data including the disease progress were collected. To investigate potential pro-inflammatory dietary habits in a patient's usual diet, food-based index of dietary inflammatory potential score (FBDI), glycemic index (GI), and glycemic load (GL) were calculated. Diet quality was evaluated using a tool called Diet Quality Index-international (DQI). Results Although most patients showed adequate caloric intake, 72% of the enrolled patients had a potential pro-inflammatory pattern identified as FBDI. The FBDI was significantly associated with intake of mixed coffee and sweeten drinks, beef, and pork (P &amp;lt; 0.05). Patients who had a serious clinical course such as history of surgery or the use of biologics, tended to have a higher FBDI (6.45 vs 2.44, P = 0.08), and showed a higher proportion with a low DQI (53% vs 20%, P = 0.06). Only 30% of the high FBDI group showed deep remission after 12 to 18 months of follow-up endoscopic or image study, whereas 72.7% of the low FBDI group showed deep remission (P =0.05). A significantly positive correlation was derived between FBDI and GL (r =0.452, P = 0.02). Conclusion For the care of patients with CD, it is necessary to evaluate the dietary quality as well as the total nutrient intake, and we need to educate the patients that dietary habits can affect the disease prognosis.

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 objectiveDue 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.MethodsThis 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.ResultsThe 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.ConclusionIn 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.

Influence of Food Purchase Behaviour on Diet Quality of University Athletes during COVID-19 Lockdown

Lockdown order during the COVID-19 pandemic creates new norms of lifestyle, including food accessibility. To understand whether this situation might affect food purchase behaviour (FPB) and diet quality in exceptional people such as athletes, online FPB and diet quality index-international (DQI-I) questionnaires were distributed to 299 university athletes but only 195 responded. The survey found FPB score of respondents was 63.3±14.1, whereas the DQI-I score was 61.8±13.2. A strong relationship between FPB and DQI-I scores, r(193) = .64, p&lt;.00001, was determined. FPB and DQI-I were not affected by gender, age and college seniority differences. Keywords: Food purchase behaviour, diet quality index, athletes, COVID-19 eISSN: 2398-4287 © 2022. The Authors.

Avocado Intake Among Adolescents Is Associated with Higher Diet Quality and Healthier Dietary Intake

ObjectivesAvocado is a nutrient-rich food that has been shown to benefit the health and diet quality of adults. Our aim is to determine if habitual intake of avocado among adolescents is associated with their diet quality and food and nutrient intake.MethodsIn this cross-sectional study, participants aged 12–18 years old (n = 534) from selected public and middle-high schools near two major Adventist universities reported their dietary intake in a validated web-based food frequency questionnaire (FFQ). Intake of nutrients, food/food groups, and avocado were calculated from the FFQ; diet quality was determined using the Diet Quality Index-International (DQI-I). Data was analyzed with descriptive statistics, comparison tests, and general linear modeling using SAS 9.3 and R.ResultsCompared to non-consumers, avocado consumers had significantly higher covariate-adjusted mean scores on total DQI-I (68.3 vs. 64.6) and energy-adjusted mean scores on the DQI-I components variety (18.8 vs. 18.0) and adequacy (36.4 vs. 33.4). Avocado consumption was significantly associated with DQI-I components adequacy (β [SE] = 0.11 [.03]) and moderation (β [SE] = 0.06 [.03]). Mean intakes of fruits, vegetables, and plant protein foods, total and vegetable proteins, dietary fiber, retinol, vitamin C, calcium, magnesium, iron, and potassium were significantly higher for avocado consumers; saturated and trans fats intakes were significantly higher for non-consumers.ConclusionsIn our adolescent population, avocado consumption was associated with higher diet quality and intake of plant-based foods and the known shortfall nutrients in this population. Greater exposure to avocado may potentially improve dietary intake of adolescents.Funding SourcesHass Avocado Board.

Determinants of diet quality among mothers of young children in an urban slum area in Jakarta: Mother’s age, vegetables availability, and eating out frequency

Introduction: Poor diet quality is a major issue, and health concerns may be related to diet. Mothers with young children usually have their meals at home; thus, home food environment plays a role in determining dietary behaviours. This study examined the association between health concerns and diet quality among mothers; additionally, the effect of home food environment on this relationship was assessed. Methods: This cross-sectional study comprising 229 mothers (aged 19–49 years) with young children was conducted in an urban slum area in North Jakarta. Data were collected via interviews using a structured questionnaire. The General Health Interest Scale and Consumer Behaviour Questionnaire were used to assess health concern and home food environment, respectively. The 24-hour dietary recall method was used to calculate the Diet Quality Index-International (DQI-I) score. Spearman’s correlation, multiple linear regression, and path analysis were used to analyse the data. Results: Majority of the mothers had poor diet quality (mean DQI-I score, 41.44/100). No significant correlation between health concern and diet quality was observed. After adjusting for age, the relationship between health concern and diet quality was not mediated by vegetables availability or eating out frequency (indirect effect=0.012; p=0.096). Multiple linear regression analysis revealed age as a significant predictor of diet quality (B=0.196; p=0.024). Conclusion: Diet quality among mothers of young children differed with age and was related to both health concerns and home food environment. Thus, the development of strategies to promote healthy eating based on different age groups is warranted.
