Abstract
The methods for controlling weight play a central role in formally diagnosed eating disorders (EDs) and appear to be important in the context of other nonformally recognized disorders, such as orthorexia nervosa (ON). These methods also have an impact on eating behaviors, including dietary variety. Our study aimed to: (i) assess the intensity of ON tendency by sex and BMI groups, (ii) evaluate the associations between ON tendency, weight control methods, and dietary variety, and (iii) determine the extent to which weight control methods and dietary variety contribute to the ON tendency among both females and males. Data were gathered from a sample of 936 Polish adults (463 females and 473 males) through a cross-sectional quantitative study conducted in 2019. Participants were requested to complete the ORTO-6, the Weight Control Methods Scale, and the Food Intake Variety Questionnaire (FIVeQ). Multiple linear regression analysis was employed to evaluate associations between ON tendency, weight control methods, and dietary variety. Females exhibited a higher ON tendency than males (14.4 ± 3.4 vs. 13.5 ± 3.7, p < 0.001, d = 0.25). In the regression model, the higher ON tendency was predicted by more frequent use of weight control methods, such as restricting the amount of food consumed, using laxatives, and physical exercise among both females and males as well as following a starvation diet in females, and drinking teas to aid bowel movements among males. Moreover, the higher ON tendency was predicted by higher dietary variety, lower age in both sexes, and higher level of education among males. However, there were no differences in ON tendency across BMI groups. In conclusion, the findings showed that ON tendency was predicted by a higher frequency of weight control methods commonly used by individuals with anorexia nervosa (AN) and bulimia nervosa (BN). The resemblance to these two EDs is also suggested by the higher intensity of ON tendency among females and younger people. However, the prediction of ON tendency by dietary variety indicates that the obsessive preoccupation with healthy eating may not be advanced enough to observe a decrease in the dietary variety among these individuals.

Abstract
OBJECTIVE Food anxiety and limited dietary variety often persist after intensive treatment for eating disorders (EDs) and may contribute to relapse. Prior studies demonstrate decreased meal-related anxiety with residential or inpatient treatment, but less is known about changes in dietary variety and anxiety associated with specific foods. The current study assessed change in food anxiety and dietary variety in inpatients with EDs (anorexia nervosa and bulimia nervosa) in relation to discharge outcomes from meal-based behavioral treatment. METHOD Patients (N = 128) admitted to a specialized, hospital-based behavioral treatment program completed measures of food anxiety, dietary variety, and ED symptoms at admission and discharge. Demographic and clinical data were abstracted from electronic medical records. A novel network community analysis identified three food anxiety groups: fruit-veg, animal-based, and carb-based foods. RESULTS High-energy density combination foods were most anxiety-provoking and most avoided. Food anxiety decreased, and dietary variety increased from admission to discharge. Reduction in food anxiety was associated with lower ED symptom scores and higher normative eating self-efficacy at discharge. For animal-based foods, increased dietary variety was associated with lower food anxiety at discharge. Neither variety nor anxiety was associated with weight restoration. DISCUSSION Findings highlight the importance of broadening dietary variety and targeting food anxiety during the nutritional rehabilitation and weight restoration phase of ED treatment. Increasing dietary variety may contribute to reduced food anxiety, which, in turn, may increase normative eating self-efficacy. These results may help inform nutritional guidelines for meal-based treatment programs. PUBLIC SIGNIFICANCE Consuming a greater variety of foods during meal-based intensive treatment may help alleviate food anxiety in patients with eating disorders.

Abstract
Diet is considered as a major driver of gut microbiota composition. However, little is known about the relationship between overall dietary balance and gut microbiota, especially in the elderly. Here, using the Quantitative Index for Dietary Diversity (QUANTIDD), we analysed the relationships between dietary diversity and gut microbiota diversity in 445 Japanese subjects aged 65-90 years. We also examined the effect of age by comparing the young-old group aged 65 to 74 years (<75 years group; n=246) and the old-old group aged 75 years and older (≥75 years group; n=199). QUANTIDD showed significant positive relationships with Pielou's evenness and Shannon indices, two α-diversity indices related to the uniformity of species distribution. This suggests that a more diverse diet is associated with a more uniform abundance of various bacterial groups, rather than a greater variety of gut bacteria. QUANTIDD also showed significant positive associations with the abundance of Anaerostipes, Eubacterium eligens group, and Eubacterium ventriosum group, which produce short-chain fatty acids (SCFAs) and are beneficial to health. Negative association was found with the abundance of Ruminococcus gnavus group, which produces inflammatory polysaccharides. Positive associations between QUANTIDD and α-diversity indices or the abundance of specific bacterial groups were identified among all subjects and in the <75 years group, but not in the ≥75 years group. Our results suggest that dietary diversity contributes to the diversity of the gut microbiota and increases the abundance of SCFAs-producing bacteria, but only up to a certain age. These findings help to understand the complex relationship between diet and gut microbiota, and provide hints for specific dietary interventions to promote beneficial gut microbiota in the elderly.

Abstract
The validity of dietary variety score (DVS) using a short-form questionnaire has not been investigated using dietary diversity based on a quantitative distribution of consumed foods in older Japanese. We examined the association between DVS and objective dietary diversity using a Quantitative Index for Dietary Diversity (QUANTIDD) based on the quantitative distribution of foods consumed by older Japanese community dwellers. The subjects were 65 older Japanese community dwellers aged 60?79 years. We used two kinds of scores for assessment of dietary diversity. At first, dietary diversity was determined using DVS calculated from answers to a questionnaire about frequencies of intake of 10 food groups. Second, dietary intake was assessed using a 3-day dietary record with photographs, and dietary diversity was determined using QUANTIDD. The relationships between DVS and QUANTIDD were assessed using partial correlation coefficients controlling for confounders. The correlation coefficient between DVS and QUANTIDD was moderate (r=0.212-0.458). After controlling for confounders, those correlation coefficient between DVS and QUANTIDD remained moderate. The findings suggest that there was a moderate relationship between DVS and QUANTIDD, and DVS using a short-form questionnaire may be useful for assessing dietary diversity in older Japanese community dwellers.

Abstract
OBJECTIVES To examine whether eating status and dietary variety were associated with functional disability during a 5-year follow-up analysis of older adults living in a Japanese metropolitan area. DESIGN A 5-year follow-up study. SETTING Ota City, Tokyo, Japan. PARTICIPANTS A total of 10,308 community-dwelling non-disabled adults aged 65-84 years. MEASUREMENTS Eating status was assessed using a self-reported questionnaire. Dietary variety was assessed using the dietary variety score (DVS). Based on the responses, participants were classified according to eating alone or together and DVS categories (low: 0-3; high: 4-10). Functional disability incidence was prospectively identified using the long-term care insurance system's nationally unified database. Multilevel survival analyses calculated the adjusted hazard ratio (HR) and 95% confidence interval (CI) for incident functional disability. RESULTS During a 5-year follow-up, 1,991 (19.3%) individuals had functional disabilities. Eating status or DVS were not independently associated with incident functional disability. However, interaction terms between eating status and DVS were associated with functional disability; HR (95% CI) for eating together and low DVS was 1.00 (0.90-1.11), eating alone and high DVS was 0.95 (0.77-1.17), and eating alone and low DVS was 1.20 (1.02-1.42), compared to those with eating together and high DVS. CONCLUSION Older adults should avoid eating alone or increase dietary variety to prevent functional disability. This can be ensured by providing an environment of eating together or food provision services for eating a variety of foods in the community.

Abstract
Nutritional factors, including low protein intake and poor dietary variety, affect age-associated impairment in physical performance resulting in physical frailty. This cross-sectional study investigated the association between intake frequency of major high protein foods and both physical performance and higher-level functional capacity using the food frequency score (FFS) and high protein food frequency score (PFFS) among community-dwelling older adults. The data of 1185 older adults categorized into quartiles based on FFS and PFFS were analyzed. After adjusting for covariates, FFS and PFFS were significantly associated with physical performance [FFS, usual gait speed (p for trend = 0.007); PFFS, usual gait speed (p for trend < 0.001), maximum gait speed (p for trend = 0.002), timed up and go (p for trend = 0.025)], and higher-level functional capacity [FFS (p for trend < 0.001); PFFS (p for trend < 0.001)]. After excluding PFFS data, the participants’ scores were associated with only higher-level functional capacity. Multi-regression analysis with higher-level functional capacity as the covariate showed that FFS and PFFS were significantly correlated with physical performance. Hence, improving food intake frequency, particularly that of high protein foods, and dietary variety may help maintain higher-level functional capacity and physical performance in community-dwelling older adults.

Abstract
BACKGROUND This 3.6-year prospective study examined combined impacts of physical activity, dietary variety, and social interaction on incident disability and estimated population-attributable fraction for disability reduction in older adults. METHODS Participants were 7,822 initially non-disabled residents (3,966 men; 3,856 women) aged 65-84 years of Ota City, Tokyo, Japan. Sufficiency of moderate-to-vigorous-intensity physical activity (MVPA) ≥150 min/week, dietary variety score (DVS) ≥3 (median), and social interaction (face-to-face and/or non-face-to-face) ≥1 time/week was assessed using self-administered questionnaires. Disability incidence was prospectively identified using the long-term care insurance system's nationally unified database. RESULTS During a follow-up of 3.6 years, 1,046 (13.4%) individuals had disabilities. Independent multivariate-hazard ratios (HRs) and 95% confidence intervals of MVPA, DVS, and social interaction sufficiency for incident disability were 0.68 (0.59-0.78), 0.87 (0.77-0.99), and 0.91 (0.79-1.03), respectively. Incident disability HRs (95% CIs) gradually reduced with increased frequency of satisfying these behaviors (any one: 0.82, 0.65-1.03; any two: 0.65, 0.52-0.82; and all three behaviors: 0.54, 0.43-0.69), in an inverse dose-response manner (P < 0.001 for trend). Population-attributable fraction for disability reduction in satisfying any one, any two, and all three behaviors were 4.0% (-0.2, 7.9), 9.6% (4.8-14.1), and 16.0% (8.7-22.8), respectively. CONCLUSION Combining active physical activity, dietary variety, and social interaction substantially enhances the impacts on preventing disability among older adults, with evidence of an inverse dose-response manner. Adding the insufficient behavior element to individual habits and preexisting social group activities may be effective in preventing disability in the community.

Abstract
Objectives This study examined the effects of checking the "Tabepo Check Sheet," which has 10 food groups, on changes in dietary variety among older adults living in Japanese metropolitan areas.Methods We used baseline and two-year follow-up data from a community-wide intervention to prevent frailty in Ota City, Tokyo. A total of 8,635 non-disabled residents (4,145 men and 4,490 women) aged 65-84 years who responded to the self-administered questionnaire surveys in 2016 and 2018, were included in the two analyses. In 2018, we asked about their experience with the "Tabepo Check Sheet," which had been distributed among participating communities from three districts in Ota City since July 2017. The "checked group" consists of those who answered "habitually check" or "have checked." Dietary variety was assessed using the Dietary Variety Score (DVS). We performed propensity score matching with a 1:1 ratio (checked group vs. non-checked group) for the following variables: demographic, socioeconomic, physical, medical, and lifestyle variables, and DVS. After propensity score matching, 876 participants from the checked and non-checked groups were selected. We used a two-way ANOVA to examine the changes in DVS over two years. We also compared the rates of DVS ≤3 and ≥7 points in 2018 using multivariate adjusted logistic regression analysis.Results In 2018, 11.9% of the respondents had checked the "Tabepo Check Sheet." The DVS mean±standard deviation in the checked and non-checked groups were 3.9±2.2 points and 3.9±2.3 points in 2016, respectively, and 4.5±2.4 points and 4.1±2.4 points in 2018, respectively. The DVS showed a significant interaction between checking experience and time (p<0.001). The rates of DVS ≤3 points in 2018 were 35.2% and 43.8% among the checked and non-checked groups, respectively. The multivariate adjusted odds ratio (OR) of DVS ≤3 points was 0.68 (95% confidence interval [95% CI] 0.56-0.83) in the checked group versus the non-checked group. The rates of DVS ≥7 points in 2018 were 21.7% and 16.8% among the checked and non-checked groups, respectively. The multivariate adjusted OR (95% CI) of DVS ≥7 points was 1.40 (1.10-1.78) in the checked versus the non-checked group.Conclusions These results suggest that checking the "Tabepo Check Sheet" may improve dietary variety. However, the effects of dietary variety improvement may be weakened by the incidence of skipped meals, social isolation, frailty, and lack of social participation.

Abstract
OBJECTIVES This study aimed to investigate the influences of living arrangements on the association between dietary variety and frailty by gender in community-dwelling older people. DESIGN A cross-sectional study. SETTING Nishinomiya city, Hyogo prefecture, Japan. PARTICIPANTS A total of 4,996 randomly selected community-dwelling older people aged 65 years and older and living in Nishinomiya City. MEASUREMENTS Survey questionnaires were distributed via mail. The frailty score was evaluated by the 5-item frailty screening index. Dietary variety was assessed using the dietary variety score developed for the general older Japanese population. RESULTS A total of 2,764 community-dwelling participants aged ≥ 65 years responded to the questionnaires. After excluding missing data, 1,780 participants were included in the study analysis. The frailty scores in older men living alone were significantly higher than those in older men living with someone (P < 0.001). The dietary variety scores in older men living alone were significantly lower than those in older men living with someone (P < 0.001). However, differences in the frailty and dietary variety scores between living alone and living with someone were not were observed in older women (P = 0.360 and P = 0.265, respectively). In the multivariable regression analysis, the associations between dietary variety score and frailty score in living alone (β= -0. 271, P = 0.011) were stronger than those in living with someone in the case of older men (β= -0.131, P = 0.045). Similar associations between dietary variety and frailty were presented in older women living alone than in those living with someone (β -0.114, P = 0.002; β -0.088, P = 0.012, respectively). CONCLUSIONS Older men who live alone had higher frailty score and lower dietary variety. The associations between dietary variety and frailty were different according to living arrangements in both older men and older women.

Abstract
BACKGROUND The dietary variety score (DVS), a simple dietary survey method for older adults, investigates the weekly frequency of consumption of the 10 food groups in Japan. The DVS is also associated with nutritional status. The original scoring method applied only to community-dwelling older adults, not to older patients receiving home care, who have little dietary variety. AIM Using three different scoring methods for the DVS, we examined which method was most likely to reflect the nutritional status of older patients receiving home care. METHODS This cross-sectional study was carried out on older patients receiving home care. Participant characteristics, the DVS (evaluated using three different scoring methods), and the Mini Nutritional Assessment-Short Form (MNA® -SF) survey were researched. A receiver operating characteristic (ROC) analysis was performed to find the cut-off value for the DVS. Multivariate analysis was performed, with malnutrition as the outcome, to investigate the extent to which the DVS is associated with malnutrition. RESULTS We studied 317 participants. The DVS could produce significant ROC curves using modified scoring methods A and B (p = .028 and .042) with nutritional status as the outcome. Cut-off value, sensitivity and specificity were 30 points, 60.9% and 55.9% in modified scoring method A and 5 points, 79.1%, and 35.6% in modified scoring method B. Results of the multivariate logistic regression analysis, in Model 1 dysphagia (odds ratio [95% confidence interval]: 3.85 [1.70-8.71]) and the DVS of modified scoring method A (2.00 [1.11-3.62]) were significant independent factors. In Model 2, dysphagia (3.57 [1.58-8.07]) and the DVS based on modified scoring method B (2.36 [1.24-4.47]) were significant independent factors. CONCLUSIONS Modified scoring method B was found to be most suitable for the dietary assessment of older patients receiving home care. IMPLICATIONS FOR PRACTICE Even in the absence of registered dietitians, any care staff member who is involved in providing nursing services during home-visits is capable of administering a dietary survey, when using the easy DVS scoring method.

Abstract
Objectives This study aimed to investigate the practice of eating alone, including its frequency, among urban older Japanese adults and to clarify its association with dietary variety.Methods In June 2016, self-reported questionnaires were mailed to 15,500 men and women aged 65 years or older living in Ota City, Tokyo without nursing care certification. Of these, 11,925 questionnaires were returned (a 76.9% response rate), and responses from 8,812 subjects were analyzed (a 56.9% valid response rate). The frequency of eating alone, defined as the number of days per week eating alone for each meal, was reported as zero, one to three, four to six, or seven days. A Dietary Variety Score (DVS) was obtained based upon consumption frequencies per week of 10 food groups. Total points were calculated, and three or fewer points indicated low dietary variety. The association between eating alone and low dietary variety was analyzed by binomial logistic regression, with adjustments for potential confounding variables including age, body mass index (BMI), location, educational history, equivalent income, employment, living alone, medical history, and smoking and drinking habits.Results The results indicated that 47.1% of men and 48.5% of women ate alone at least one day per week, and 14.9% of men and 16.9% of women ate alone every day. For men, after adjusting for potential confounders (ORs=1.51-2.00), the odds ratios (ORs) of low DVSs were significantly higher among those who ate alone one to three days, four to six days, or seven days per week compared to those who ate with others. For women, adjusted ORs were not significant among those who ate alone every day (OR=1.15, 95% CI=0.92-1.43). Men and women who ate alone had significantly lower ORs of eating green or yellow vegetables, fruits, and fats/oils almost every day compared to those who ate with others.Conclusion Among urban Japanese older adults, about 50% of subjects reported eating alone. Eating alone was associated with lower dietary variety scores regardless of age, income, and family status. Therefore, the present findings might be useful for developing strategies for addressing undernutrition among urban older adults eating alone.

Abstract
OBJECTIVES This study evaluated associations of score-based and nutrient-derived dietary patterns with depressive symptoms in community-dwelling older Japanese. DESIGN Cross-sectional study. SETTING Community-based. PARTICIPANTS 982 community-dwelling adults aged 65 years or older. MEASUREMENTS Score-based pattern was assessed by using dietary variety score (DVS), which covers 10 food group items in Japanese meals. Nutrient-derived dietary patterns were identified by using reduced rank regression (RRR), with folate, vitamin C, magnesium, calcium, iron, and zinc intakes as response variables. Depressive symptoms were assessed with the Geriatric Depression Scale. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for these dietary patterns in multivariate logistic regression analyses with potential confounders. The lowest consumption category was used as the reference group. RESULTS The prevalence of depressive symptoms was 13.5%. Higher DVS was associated with fewer depressive symptoms (OR=0.52, 95% CI=0.27-1.03 for the highest vs the lowest DVS; P for trend=0.031). The first RRR dietary pattern score was characterized by high intakes of fish, soybean products, potatoes, most vegetables, mushrooms, seaweeds, fruits, and green tea and a low intake of rice and was inversely associated with the prevalence of depressive symptoms (OR=0.53, 95% CI=0.30-0.92; P for trend=0.030). CONCLUSION Greater dietary variety and a dietary pattern characterized by high intakes of fish, soybean products, potatoes, most vegetables, mushrooms, seaweeds, fruit, and green tea and a low intake of rice were consistently associated with lower prevalence of depressive symptoms in community-dwelling older Japanese. Therefore, both patterns identified the components of dietary habits essential to depression prevention.

Abstract
Defining dietary guidelines requires a quantitative assessment of the influence of diet on the development of diseases. The aim of the study was to investigate how dietary patterns were associated with mortality in a general population sample of Switzerland. We included 15,936 participants from two population-based studies (National Research Program 1A (NRP1A) and Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA)—1977 to 1993) who fully answered a simplified 24-h dietary recall. Mortality data were available through anonymous record linkage with the Swiss National Cohort (follow-up of up to 37.9 years). Multiple correspondence analysis and hierarchical clustering were used to define data-driven qualitative dietary patterns. Mortality hazard ratios were calculated for all-cause, cancer and cardiovascular mortality using Cox regression. Two patterns were characterized by a low dietary variety (“Sausage and Vegetables”, “Meat and Salad”), two by a higher variety (“Traditional”, “High-fiber foods”) and one by a high fish intake (“Fish”). Males with unhealthy lifestyle (smokers, low physical activity and high alcohol intake) were overrepresented in the low-variety patterns and underrepresented in the high-variety and “Fish” patterns. In multivariable-adjusted models, the “Fish” (hazard ratio = 0.82, 95% CI (0.68–0.99)) and “High-fiber foods” (0.85 (0.72–1.00)) patterns were associated with lower cancer mortality. In men, the “Fish” (0.73 (0.55–0.97)) and “Traditional” (0.76 (0.59–0.98)) patterns were associated with lower cardiovascular mortality. In summary, our results support the notion that dietary patterns affect mortality and that these patterns strongly cluster with other health determinants.

Abstract
BACKGROUND Dietary variety is defined as the number of different foods or food groups consumed over a given reference period, the consensus being that dietary variety and dietary quality are positively correlated. Recently there has been considerable interest in the association between infant dietary variety and atopic disease. METHODS This was a cross-sectional study of 8- to 27-month-old children from the Isle of Wight, UK, including two groups: a group of children consuming a cows' milk exclusion (CME) diet and a control group of children consuming an unrestricted diet. Parents completed a validated food frequency questionnaire, from which dietary variety and consumption of food groups were calculated. Growth measurements were recorded. RESULTS A total of 126 participants of mean age 13.0 months were recruited. In addition to the expected differences in dairy and soya consumption, the CME group consumed sweet foods 1.6 times less frequently, non-water drinks seven times less frequently (p < 0.05) and ready-made baby foods 15 times more frequently (p < 0.01) than the control group. Overall dietary variety was significantly lower in the CME group (p < 0.01) as was variety of meat and sweet foods consumed. There was a greater concern with healthy eating in the CME group (p < 0.05). CONCLUSIONS Children consuming an exclusion diet for cows' milk allergy have an overall less varied diet, including a less varied consumption of meat and sweet foods. Efforts should be made to ensure exclusion diets are as varied as possible to optimize nutritional intake.

Abstract
BACKGROUND Consuming a wider variety of nutrient-dense foods may promote adherence to healthful dietary patterns, leading to improved dietary quality and enhanced metabolic health. OBJECTIVE We used the US Healthy Food Diversity (HFD) index to simultaneously measure dietary variety, quality, and proportionality, hypothesizing a priori that race/ethnicity may moderate associations between diet and health. METHODS A representative sample of adults (n = 7470) aged 20+ y with two 24-h recalls and complete outcome data from the cross-sectional NHANES 2003-2006 were selected. US HFD values were generated using a previously validated equation with a theoretical range from 0 to nearly 1, with higher scores indicative of more varied diets with a higher proportion of healthful food groups. Metabolic syndrome (MetS) was defined using the most recent harmonized definition. Survey-weighted multivariable linear and logistic regression, adjusted for demographic factors, smoking, energy, screen time, and leisure activity, were used to compute means and ORs (95% CIs). RESULTS Adults in the third vs. first US HFD tertile had 21% lower odds of MetS [OR (95% CI): 0.79 (0.64, 0.98)] as well as lower odds of hypertension [0.83 (0.70, 0.995] and elevated waist circumference [0.75 (0.66, 0.86] after multivariable adjustment (P-trend < 0.05). The age- and sex-adjusted odds of low serum HDL cholesterol and impaired fasting plasma glucose (P-trend < 0.05) were lower in the highest vs. lowest US HFD tertile but attenuated with multivariable adjustment (P = 0.06 and 0.22, respectively). Notably, the US HFD index was only protective against adiposity among non-Hispanic white (NHW) and non-Hispanic black (NHB) adults, and MetS associations were driven by NHW adults. No associations were observed among Hispanic adults for any MetS components. CONCLUSIONS Greater healthful food variety was associated with lower odds of MetS and some MetS components in the total population, NHW adults, and NHB adults. This study provides preliminary evidence that healthful food diversity may protect against MetS and highlights the need for longitudinal and experimental research.

Abstract
BACKGROUND Consuming a variety (vs. monotony) of energy-poor, nutrient-dense foods may help individuals adhere to dietary patterns favorably associated with weight control. OBJECTIVE The objective of this study was to examine whether greater healthful food variety quantified using the US Healthy Food Diversity (HFD) index favorably influenced body adiposity. METHODS Men and nonpregnant, nonlactating women aged ≥20 y with two 24-h recalls from the cross-sectional NHANES 2003-2006 (n = 7470) were included in this study. Dietary recalls were merged with the MyPyramid Equivalent database to generate the US HFD index, which ranges from 0 to ∼1, with higher scores indicative of diets with a higher number and proportion of healthful foods. Multiple indicators of adiposity including BMI, waist-to-height ratio, android-to-gynoid fat ratio, fat mass index (FMI), and percentage body fat were assessed across US HFD index quintiles. ORs and 95% CIs were computed with use of multivariable logistic regression (SAS v. 9.3). RESULTS The US HFD index was inversely associated with most adiposity indicators in both sexes. After multivariable adjustment, the odds of obesity, android-to-gynoid ratio >1, and high FMI were 31-55% lower (P-trend < 0.01) among women in quintile 5 vs. quintile 1 of the US HFD index. Among men, the odds of obesity, waist-to-height ratio ≥0.5, and android-to-gynoid ratio >1 were 40-48% lower (P-trend ≤ 0.01) in quintile 5 vs. quintile 1 of the US HFD index. CONCLUSIONS Higher US HFD index values were inversely associated with indicators of body adiposity in both sexes, indicating that greater healthful food variety may protect against excess adiposity. This study explicitly recognizes the potential benefits of dietary variety in obesity management and provides the foundation to support its ongoing evaluation.

Abstract
BACKGROUND/OBJECTIVES Neophobia, pickiness and diet variety are associated with diet quality and health outcomes in young children. Limited research has examined these associations among youth with type 1 diabetes (T1D), a population at risk for poor health outcomes when dietary quality is inadequate. SUBJECTS/METHODS Youth (n=252, age 13.2 ± 2.8 years, 92% white, diabetes duration 6.3 ± 3.4 years) with T1D and their parents completed 3-day youth diet records; parents completed questionnaires regarding youth neophobia, pickiness and diabetes management adherence. Medical records provided biomedical data. Dietary quality indicators included Nutrient-Rich Foods Index 9.3 (NRF9.3), Healthy Eating Index-2005 (HEI-2005), Whole Plant Food Density (WPFD) and key single nutrients. Dietary variety was operationalized as a count of 20 recommended food groups consumed. Relationships of dietary quality and diabetes management adherence with neophobia, pickiness and dietary variety as independent variables were examined using multiple linear regression analyses adjusted for total energy intake, age, height and weight. RESULTS In multiple linear regression analyses, NRF9.3 and HEI-2005 were each inversely associated with neophobia and pickiness, and positively associated with dietary variety. WPF and potassium were each positively associated and saturated fat was inversely associated with dietary variety. However, in models simultaneously including neophobia, pickiness and dietary variety as independent correlates of dietary quality, only relationships with dietary variety remained significant. Diabetes management adherence was negatively associated with both neophobia and pickiness and positively associated with dietary variety. CONCLUSIONS Findings suggest that increasing dietary variety may contribute toward improved dietary quality among youth with T1D, despite potentially adverse influences of neophobia and pickiness.

Abstract
OBJECTIVE The purpose of these studies was to test the hypothesis that dietary variety decreases the rate of habituation and increases energy intake in children. DESIGN In Experiment 1, salivation in response to the same or a variety of food cues was measured followed by consumption of the study food(s). In Experiment 2, children responded in a computer task to earn points for the same or a variety of low or high energy density foods, which were then consumed. MAIN OUTCOME MEASURES Salivation, number of responses, and energy intake were measured. RESULTS Participants in the same groups habituated faster than those in the variety groups (p = .05), and in Experiment 2, the effect of variety was independent of energy density. Participants in the variety groups also consumed more energy than those in the same groups in both experiments (p = .05). CONCLUSIONS Dietary variety disrupted habituation and increased energy intake in children. In addition, the response to dietary variety was independent of energy density, suggesting that increasing variety of low energy density foods may increase consumption.

Abstract
CONTEXT Increased dietary variety has been associated with increased body weight; however, diet variety is not measured using a standardized methodology. OBJECTIVE We developed a new dietary variety score (DVS) based on food macronutrient content, and determined the relationship between DVS and measures of adiposity. DESIGN Cross-sectional, observation study. SETTING University of Alabama at Birmingham (UAB), EatRight Weight Management Program. PATIENTS Study subjects (n = 74) were former participants of UAB's EatRight Weight Management Program who completed the program at least 1 year ago. MAIN OUTCOME MEASURES Unique items from 4-day food records were converted to macronutrient categories using the diabetic exchange. Foods were categorized as a source of carbohydrate if containing > or = 5 g carbohydrate and > or = 20 calories; fat if containing > or = 5 g fat; protein if containing > or = 7 g protein. Height and weight were measured; BMI (kg/m2) was calculated. Dual energy X-ray absorptiometry measured body fat. Generalized linear modeling in SAS (Ver.9) determined relationships between adiposity and DVS. RESULTS On average, participants weighed 92.7 -/+ 30.9 kg (BMI = 32.5 kg/m2). Men and women's body fat were 37.4 -/+ 6.4% and 47.3 -/+ 6.4%, respectively. Separate linear regression models containing terms for sex and DVS showed significant relationships between macronutrient DVS and BMI. In a multivariate model controlling for each of the macronutrient DVS, BMI was not related to fat DVS, but was found to be positively related to protein DVS (beta = 0.87, P = .04). Sex modified the relationship between carbohydrate DVS and BMI, with an inverse relationship between BMI and carbohydrate DVS among women, and a positive relationship among men. Percent body and trunk fat were not related to DVS for either gender. CONCLUSIONS The new DVS, based on macronutrient content of foods, had significant associations with BMI. These dietary variety scores may provide another way to evaluate the impact of consuming a variety of food types on energy intake and BMI.
