Post hoc analysis of food costs associated with Dietary Approaches to Stop Hypertension diet, whole food, plant-based diet, and typical baseline diet of individuals with insulin-treated type 2 diabetes mellitus in a nonrandomized crossover trial with meals provided.

BACKGROUND: Americans consume diets that fall short of dietary recommendations, and the cost of healthier diets is often cited as a barrier to dietary change. We conducted a nonrandomized crossover trial with meals provided utilizing 2 diets: Dietary Approaches to Stop Hypertension (DASH) and whole food, plant-based (WFPB), and thus had intake data from baseline and both intervention diets. OBJECTIVES: Using actual diet records, describe food costs of baseline diets of individuals with type 2 diabetes (T2DM) as well as therapeutic DASH and WFPB diets. METHODS: Three-day food records were collected and analyzed for each 7-d diet phase: baseline, DASH, and WFPB. Nutrient content was analyzed using the Nutrient Data System for Research and cost was determined using Fillet, an application to manage menu pricing. Food costs were calculated for each diet as consumed and adjusted to a standardized 1800 kcal/d. Ingredient-only costs of food away from home (FAFH) were approximated and analyzed. Costs were analyzed using linear mixed-effect models as a function of diet. RESULTS: Fifteen subjects enrolled; 12 completed all dietary phases. The baseline, DASH, and WFPB diets, as consumed, cost $15.72/d (95% CI; $13.91, $17.53), $12.74/d ($11.23, $14.25), and $9.78/d ($7.97, $11.59), respectively. When adjusted to an 1800 kcal/d intake, the baseline, DASH, and WFPB diets cost $15.69/d ($13.87, $17.52), $14.92/d ($13.59, $16.26), and $11.96/d ($10.14, $13.78), respectively. When approximated ingredient-only costs of FAFH were analyzed, as consumed baseline [$11.01 ($9.53, $12.49)] and DASH diets [$11.81 ($10.44, $13.18)] had similar costs; WFPB diet [$8.83 ($7.35, $10.31)] cost the least. CONCLUSIONS: In this short-term study with meals provided, the food costs of plant-predominant diets offering substantial metabolic health benefits were less than or similar to baseline food costs of adults with insulin-treated T2DM. Longer-term data without meal provision are needed for more generalizable results. This trial was registered at clinicaltrials.gov as NCT04048642.

Using Community-Based Participatory Research Methods to Inform the Development of Medically Tailored Food Kits for Hispanic/Latine Adults with Hypertension: A Qualitative Study.

The Dietary Approaches to Stop Hypertension (DASH) eating plan is the most effective dietary intervention for cardiovascular disease (CVD), but it excludes the consideration of culture and cost. The Hispanic/Latine population is disproportionately affected by CVD, with risks increasing if persons are accustomed to a Westernized diet. This research aims to understand the cultural dietary practices aligned with a DASH eating plan and the social determinants of health impacting fruit and vegetable (F/V) consumption among immigrant Hispanic/Latine individuals at a community-based clinic in Minnesota. Utilizing community-based participatory research methods, a community survey informed the development of DASH-focused, medically tailored food kits of varying F/V modalities. Qualitative feedback was sought out regarding the kits when presented to 15 individuals during in-depth interview sessions to validate the cultural appropriateness of food kits for clinical use. Box A was the highest rated kit (66.7%) and consisted of fresh F/V. The average F/V consumption per day was 2.6 ± 1.4 servings. The food insecurity questionnaires showed high/marginal (40%), low (53.3%), and very low (6.7%) food security. The barriers to consuming F/V were money, time, and transportation. Understanding cultural dietary practices related to the DASH eating plan is necessary to mitigate CVD risk and provide inclusive medical nutrition therapy for Hispanic/Latine populations.

Relation of the Dietary Approaches to Stop Hypertension Dietary Pattern to Heart Failure Risk and Socioeconomic Status (from the Southern Community Cohort Study).

The Dietary Approaches to Stop Hypertension (DASH) dietary pattern has been associated with a lower risk of incident heart failure (HF); however, previous studies were conducted in mostly middle-income White populations. The association between DASH and incident HF risk in lower income and Black individuals is less well understood. We analyzed 25,300 White and Black adults without a history of HF at enrollment (2002 to 2009) in the Southern Community Cohort Study receiving Centers for Medicare and Medicaid Services. Alignment with DASH was assessed at enrollment using a validated food frequency questionnaire. Incident HF was ascertained from Centers for Medicare and Medicaid Services claims through 2016. The association between DASH diet alignment and incident HF was examined in multivariable-adjusted Cox proportional hazards regression models, including an interaction term testing effect modification by income. The cohort was predominantly middle-aged (median 54 years), Black (68%), female (63%), and low-income (88% <$25,000/year/household). Socioeconomic factors, including education and annual income, were larger contributors to the variance in DASH score than were cardiovascular co-morbidities. The association between DASH dietary alignment and HF risk was not significant overall (hazard ratio [HR] 1.00; 95% confidence interval [CI] 0.96 to 1.04) or in race-sex groups. However, the association between alignment with the DASH diet and HF risk significantly varied by income (interaction p = 0.030), with neutral and inverse associations in lower (<$25,000/year) and higher ($≥25,000) income participants, respectively. In conclusion, income modified the association between healthier dietary patterns and risk of incident HF. In lower income participants, greater alignment with the DASH diet was not associated with lower HF risk.

Development, Validation, and Reproducibility of Food Group-Based Frequency Questionnaires for Clinical Use in Brazil: A Pre-Hypertension and Hypertension Diet Assessment.

The Blood pressure control diet is well described; however, it has not been implemented in clinical care, possibly due to the impracticability of the diet assessment in these contexts. In order to facilitate the dietary assessment, we developed and assessed the validity and reproducibility of two food group-based food frequency questionnaires (FG-FFQs), with a one-week (7-day FG-FFQ) and a one-month (30-day FG-FFQ) period of coverage for patients with pre-hypertension or hypertension. In 2010, 155 men and women, 30-70 years old, were invited to participate in a prospective study in two outpatient clinics in Porto Alegre, southern Brazil. The participants responded to two 30-day, two 7-day FG-FFQ, four 24-h dietary recalls, and underwent demographic, anthropometric, and blood pressure assessments. The validity and reproducibility were assessed using partial correlation coefficients adjusted for sex and age, and the internal validity was tested using the intra-class correlation coefficient. The participants were aged 61 (±10) years and 60% were women. The validity correlation coefficient was higher than r = 0.80 in the 30-day FG-FFQ for whole bread (r = 0.81) and the 7-day FG-FFQ for diet/light/zero soda and industrialized juices (r = 0.84) in comparison to the 24-h dietary recalls. The global internal validity was α = 0.59, but it increased to α = 0.76 when 19 redundant food groups were excluded. The reproducibility was higher than r = 0.80 for pasta, potatoes and manioc, bakery goods, sugar and cocoa, and beans for both versions. The 30-day had a slightly higher validity, both had good internal validity, and the 7-day FG-FFQ had a higher reproducibility.

[Assessment of the professional community awareness about innovative diets prescribed for hypertension].

Due to the fact of constantly increasing incidence of arterial hypertension and the large role of nutrition in the treatment and prevention of this disease, the assessment of the awareness of the medical community and patients about the trends in the development of therapeutic and prophylactic diets is relevant. The aim of the research was to assess the physician and patient awareness on the trends in the development of therapeutic and prophylactic diets and different rations prescribed for hypertension prevention. Material and methods. On the SurveyMonkey platform, questionnaires were created for different medical specialties and patient of various departments. Access to the survey was free, the mailing list was carried out through the professional communities of physicians on the Internet. In turn, the doctors-respondents were asked to distribute the link for patients among those who were undergoing treatment or were on dispensary observation for the pathology of the cardiovascular system. Respondents were asked about their attitudes, knowledge, and compliance with existing dietary guidelines. The number of respondents was 300 doctors of various specialties and 300 patients. Results. The most recognizable dietary recommendations among patients were: low-calorie (41.1%), low-carbohydrate (39.4%), vegetarian (39.0%). However, the most popular (the commitment to them was the greatest) were: low in calories (27.6%), low in carbohydrates (25.6%), low in fat (24.4%). Among the doctors, the distribution was as follows - in addition to the classic therapeutic and prophylactic diets prescribed for certain diseases, the most recognizable diets were: Mediterranean (59.8%), low-calorie (59.0%), low-fat (57.3%); and the most commonly prescribed: Mediterranean (47.0%), low-carb (44.4%), low-fat (40.2%). The most recognizable dietary pattern among patients was the low-calorie diet (adherence to it was also maximum). As for physicians, the most recognized and most recommended preventively was the Mediterranean eating pattern. At the same time, the prevalence and recognition of the DASH diet, which, according to the opinion of the world community, has the most pronounced preventive and therapeutic properties, according to the survey, was low (7.3% of the respondents were aware of this diet). Conclusions. According to the results of this work, it is necessary to consider the possibility of combining three diets (low-calorie, Mediterranean and DASH diets) to achieve the maximum therapeutic and preventive effect while maintaining popularity among patients.

Modelling the Cost-Effectiveness of Implementing a Dietary Intervention in Renal Transplant Recipients.

BACKGROUND: The Dietary Approach to Stop Hypertension (DASH) and potassium supplementation have been shown to reduce the risk of death with a functioning graft (DWFG) and renal graft failure in renal transplant recipients (RTR). Unfortunately, a key problem for patients is the adherence to these diets. The aim of this study is to evaluate the cost-effectiveness and budget impact of higher adherence to either the DASH or potassium supplementation. METHODS: A Markov model was used to simulate the life course of 1000 RTR in the Netherlands. A societal perspective with a lifetime time horizon was used. The potential effect of improvement of dietary adherence was modelled in different scenarios. The primary outcomes are the incremental cost-effectiveness ratio (ICER) and the budget impact. RESULTS: In the base case, improved adherence to the DASH diet saved 27,934,786 and gained 1880 quality-adjusted life years (QALYs). Improved adherence to potassium supplementation saved €1,217,803 and gained 2901 QALYs. Both resulted in dominant ICERs. The budget impact over a five-year period for the entire Dutch RTR population was €8,144,693. CONCLUSION: Improving dietary adherence in RTR is likely to be cost-saving and highly likely to be cost-effective compared to the current standard of care in the Netherlands.

Visceral adiposity index and its association with Dietary Approaches to Stop Hypertension (DASH) diet scores among older adults: National Health and Nutrition Examination Surveys 2011-2014.

BACKGROUND & AIMS: The visceral adiposity index (VAI) has been shown to be a reliable estimate of visceral adiposity, but little is known about its association with specific dietary patterns such as the Dietary Approaches to Stop Hypertension (DASH) diet, particularly in older adults. Many studies have shown the DASH diet to be beneficial for cardiometabolic health. The purpose of this study was to investigate the relationship between DASH diet scores and the VAI in older adults using a nationally representative dataset. METHODS: Using the National Health and Nutrition Examination Surveys (NHANES) from 2011 to 2014, data from 508 community-dwelling older adults were examined, and dietary intake was evaluated using the Dixon's DASH diet index. Using multiple linear regression analysis, the relationship between VAI and DASH diet score was assessed while controlling for demographic variables. RESULTS: Participants' average DASH diet score was 2.41 (SE = 0.07), and the average VAI was 1.55 (SE = 0.08). The results suggest a significant inverse relationship between the DASH diet and VAI (ß = -0.19, t = -2.73, p = 0.009). CONCLUSIONS: Results of this study suggest that protective properties of the DASH diet pattern may be due in part to its inverse relationship with visceral adiposity. This information supports practitioners' use of the VAI with older adults in addition to providing nutrition counseling with the DASH diet to reduce patients' cardiometabolic risk.

Adherence to healthy and sustainable diets is not differentiated by cost, but rather source of foods among young adults in Albania.

High cost of nutritious foods and eating out of home (OH) might be barriers to healthy and sustainable diets. We examined adherence to Dietary Approaches to Stop Hypertension (DASH), EAT-Lancet reference diet (EAT) and Mediterranean diet score (MDS) and the associations with dietary cost and eating OH. We evaluated cross-sectional data from single multiple-pass 24-h diet recalls from 289 young adults (18-24 years) in Tirana, Albania. Dietary cost (in Albanian Lek (ALL)) was estimated by matching food consumption data with retail prices from local fast-food chains, supermarkets, restaurants and food vendors. Poisson regression was fitted to models that included DASH, EAT and MDS as dependent variables to assess associations between healthy sustainable diet indicators and dietary cost and eating OH. Adjusted models were controlled for BMI, sex and total energy intake (kJ) using the residual method. Our findings indicate relatively poor adherence to healthy and sustainable dietary patterns among young men and women in Albania. Furthermore, better adherence to DASH, EAT or MDS was not associated with dietary cost (per 100 ALL; range incidence rate ratios (IRR): 0·97-1·00; all (un-)adjusted P > 0·05). Nonetheless, eating OH was related to lower adherence to DASH (IRR: 0·79; P = 0·003) and MDS (IRR: 0·69; P < 0·001). In conclusion, adherence to health and sustainable dietary patterns was poor and not differentiated by cost, but rather source of foods (i.e. OH or at home). Further research on the potential public and environmental health effects of these findings is warranted in Albania.

Chronobiologic assessment of the effect of the DASH diet on blood pressure.

This study compares the effect of three diets on the circadian rhythm of blood pressure (BP). Hypertension and abnormal BP variability (BPV) are major risk factors leading to morbidity and mortality from cardiovascular disease. When detected early, a dietary approach may be preferred to medication. Data stemming from ambulatory BP monitoring (ABPM) from the Dietary Approaches to Stop Hypertension (DASH) study were re-analyzed from a chronobiologic perspective. Compared to the control diet (N = 112) that had no effect on BP (from 131.2/83.5 to 131.0/83.6 mmHg), both the Fruit and Vegetable (FV; N = 113) diet and the DASH (N = 113) diet were associated with a decrease in BP (FV: from 132.6/84.4 to 129.0/82.1 mmHg; DASH: from 131.9/83.6 to 127.2/80.9 mmHg). The decrease in BP was found to be circadian stage-dependent, and to differ between men and women. Nighttime BP was decreased to a larger extent with the DASH than with the FV diet, a difference observed in women but not in men. Study participants who had a higher BP during the reference stage were more likely to decrease their BP to a larger extent after the 8-week dietary intervention. The FV and DASH diets had different effects on BPV. In view of the relatively large day-to-day variability in BP in both normotensive and hypertensive people, it is recommended to monitor BP around the clock for longer than 24 h, and to individualize the optimization of dietary or other intervention.

Diet Quality as Assessed by the Healthy Eating Index, Alternate Healthy Eating Index, Dietary Approaches to Stop Hypertension Score, and Health Outcomes: A Second Update of a Systematic Review and Meta-Analysis of Cohort Studies.

BACKGROUND: Suboptimal diet quality has a large impact on noncommunicable disease burden. OBJECTIVE: This study aimed to update the body of evidence on the associations between diet quality, as assessed by the Healthy Eating Index, Alternate Healthy Eating Index, and the Dietary Approaches to Stop Hypertension score, and health status. Moreover, results of the previous systematic reviews and meta-analyses were extended by evaluating the credibility of the evidence. METHODS: PubMed, Embase, and Scopus databases were searched to identify eligible studies published between May 15, 2017 and March 14, 2020. Pooled relative risk (RR) with 95% CI for highest vs lowest category of diet quality were estimated using a random-effects model. Heterogeneity was explored using Cochran's Q test and I2 statistic with 95% CI. Presence of publication bias was detected by using funnel plots and Egger's regression test. The NutriGrade tool was used to assess the credibility of evidence. RESULTS: The current update identified 47 new reports, resulting in a total of 113 reports including data from 3,277,684 participants. Diets of the highest quality, as assessed by the Healthy Eating Index, Alternate Healthy Eating Index, and Dietary Approaches to Stop Hypertension scores, were inversely associated with risk of all-cause mortality (RR 0.80, 95% CI 0.79 to 0.82, I2 = 68%, n= 23), cardiovascular disease incidence or mortality (RR 0.80, 95% CI 0.78 to 0.82, I2 = 59%, n= 45), cancer incidence or mortality (RR 0.86, 95% CI 0.84 to 0.89, I2 = 73%, n= 45), incidence of type 2 diabetes (RR 0.81, 95% CI 0.78 to 0.85, I2 = 76%, n= 16), and incidence of neurodegenerative diseases (RR 0.82, 95% CI 0.75 to 0.89, I2 = 71%, n= 12). In cancer survivors, the highest diet quality was linked with lower risk of all-cause (RR 0.83, 95% CI 0.77 to 0.88, I2 = 45%, n= 12) and cancer mortality (RR 0.82, 95% CI 0.75 to 0.89, I2 = 44%, n= 12). The credibility of evidence for identified associations between overall healthy dietary patterns and included health outcomes was moderate. CONCLUSION: This updated systematic review and meta-analysis suggests that high diet quality (assessed by the Healthy Eating Index, Alternate Healthy Eating Index, and Dietary Approaches to Stop Hypertension) is inversely associated with risk of all-cause mortality, cardiovascular disease incidence or mortality, cancer incidence or mortality, type 2 diabetes, and neurodegenerative disease, as well as all-cause mortality and cancer mortality among cancer survivors. Moderate credibility of evidence for identified associations complements the recent 2020 Dietary Guidelines Advisory Committee report recommending healthy dietary patterns for disease prevention.

Association between diet quality and obesity indicators among the working-age adults in Inner Mongolia, Northern China: a cross-sectional study.

BACKGROUND: Obesity is a major risk factor for the global burden of disease in countries that are economically developed or not. This study aimed to investigate the association between diet quality and obesity indicators applying DASH and aMed. METHODS: This cross-sectional study on adult nutrition and chronic disease in Inner Mongolia (n = 1320). Dietary data were collected using 24-h diet recall for 3 consecutive days and weighing method. DASH and aMed were used to assess the dietary quality. WC, BMI and WC-BMI were used as obesity indicators. Logistic regression models were used to examine the associations between diet quality and obesity indicators. RESULTS: Higher diet quality, assessed by DASH, was only associated with WC. The odds ratio (OR) for abdominal obesity in the highest tertile of DASH scores compared with the lowest was 0.71 (95% confidence interval (CI) 0.53, 0.96; Ptrend = 0.03). Furthermore, aMed was inversely associated with obesity indicators. OR for abdominal obesity in the highest tertile of aMed score compared with the lowest were 0.63 (95% CI 0.47, 0.87; Ptrend = 0.005) and 0.57 (95% CI 0.41, 0.77; Ptrend = 0.02) for overweight and obesity, respectively, and 0.60 (95% CI 0.44, 0.81; Ptrend = 0.02) for high obesity risk. CONCLUSIONS: Our findings suggest that dietary quality assessed using aMed is more closely associated with obesity than assessment using DASH in working-age adults in Inner Mongolia. The Mediterranean diet can be recommended as a healthy diet to control weight.

Dietary Approaches to Stop Hypertension (DASH) diet and associated socio-economic inequalities in the UK.

The Dietary Approaches to Stop Hypertension (DASH) diet is an effective measure in the prevention and treatment of CVD. We evaluated recent trends in socio-economic differences in the DASH score in the UK population, using education, occupation and income as proxies of socio-economic position (SEP). We analysed data on 6416 subjects aged 18 years and older collected in the National Diet and Nutrition Survey (2008-2016). The DASH score was calculated using sex-specific quintiles of DASH items. Multiple linear regression and quantile regression models were used to evaluate the trend in DASH score according to SEP. The mean DASH score was 24 (sd 5). The estimated mean difference between people with no qualification and those having the highest level of education was -3·61 (95 % CI -4·00, -3·22) points. The mean difference between subjects engaged in routine occupations and those engaged in high managerial and professional occupations was -3·41 (95 % CI -3·89, -2·93) points and for those in the first fifth and last fifth of the household income distribution was -2·71 (95 % CI -3·15, -2·28) points. DASH score improved over time, and no significant differences in the trend were observed across SEP. The widest socio-economic differences emerged for consumption of fruit, vegetables, whole grains, nuts, seeds and legumes. Despite an overall increase in the DASH score, a persisting SEP gap was observed. This is an important limiting factor in reducing the high socio-economic inequality in CVD observed in the UK.

Association of DASH and Depressive Symptoms with BMI over Adulthood in Racially and Socioeconomically Diverse Adults Examined in the HANDLS Study.

Adherence to the Dietary Approaches to Stop Hypertension (DASH) diet is linked to slower weight gain over time. Elevated depressive symptoms may lead to poor quality diets, potentially increasing Body Mass Index (BMI). This study explored these pathways using longitudinal data extracted from 1201-1458 Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study participants. DASH mean score was computed using four 24 h recalls [visits(v)1 + v2/2: 2004-2013] and depressive symptoms using the Center for Epidemiologic Studies Depression (CES-D) scale (v1 + v2/2: 2004-2013). BMI was measured at v2: 2009-2013 and v3: 2013-2017. Multiple linear mixed regression and mediation modeling were conducted, linking CES-D(mean) and DASH(mean) to BMI [v2 and annualized change ΔBMI (v3-v2)] and exploring mediation of the CES-D(mean)-BMI(v3) and DASH(mean)-BMI(v3) associations through DASH(mean) and CES-D(mean), respectively. Models were further stratified by sex, race and poverty status. Inverse cross-sectional and longitudinal relationships of DASH(mean) with BMI(v2) and ΔBMI were detected, mainly in women and <125% of poverty participants. CES-D(mean) was not associated with BMI(v3); no mediation was detected through DASH(mean) in all socio-demographic strata. Moreover, the inverse DASH(mean)-BMI(v3) total effect was not mediated through CES-D(mean). Future studies should explore other pathways aside from depressive symptoms by which DASH can have a preventive effect on weight status over time.

Longitudinal Associations between Monetary Value of the Diet, DASH Diet Score and the Allostatic Load among Middle-Aged Urban Adults.

Lower cost can lead to poorer-quality diets, potentially worsening metabolic profiles. We explored these pathways among urban adults. Longitudinal data were extracted from 1224-1479 participants in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study. DASH(mean) (Dietary Approaches to Stop Hypertension) score was computed using four 24 h recalls (v1/v2: 2004-2013) linked with a national food price database to estimate monetary value of the diet [MVD(mean)]. Allostatic load (AL) was measured at visits 2 (v2) and 3 (v3) in 2009-2018. Mixed-effects regression and structural equation modeling (SEM) were conducted, linking MVD(mean)/DASH(mean) to AL [v2 and annual change(v3-v2)] and exploring mediating pathways between MVD(mean) and AL(v3) through DASH(mean), stratifying by sex, race and poverty status. MVD(mean) tertiles were linearly associated with contemporaneous DASH(mean), after energy adjustment. In mixed-effects regression models, DASH(mean) was consistently linked to lower AL(v2). DASH(mean) and MVD(mean) were positively associated with higher serum albumin(v2). In SEM, MVD(mean) was linked to AL(v3) through DASH(mean), mainly among Whites and specifically for the cholesterol and Waist-Hip-Ratio AL components. In summary, energy and other covariate-adjusted increase in MVD may have a sizeable impact on DASH which can reduce follow-up AL among urban White middle-aged adults. More studies are needed to replicate findings in comparable samples of urban adults.

Empiric therapy for kidney stones.

Careful phenotyping of patients to classify those with kidney stones has a long and important history in revealing the chemical basis for stone formation. Advances in our genetic understanding of kidney stones will lead to incredible insights regarding the pathophysiology of this common disorder. At this time, both evaluation of urine chemistry and genotyping of patients are extremely useful in the setting of a university and research-based kidney stone clinic. For much of the world, in a more clinically focused setting, these techniques are neither available nor absolutely necessary. Careful implementation of an empiric prescription based on stone composition would have an important effect to reduce stone recurrence in the world's many stone formers. Increased fluid intake, generic dietary manipulations, and prescription of potassium citrate and thiazides are all appropriate empiric therapies for people with calcium and uric acid kidney stones.

Dietary gap assessment: an approach for evaluating whether a country's food supply can support healthy diets at the population level.

OBJECTIVE: Dietary diversity, and in particular consumption of nutrient-rich foods including fruits, vegetables, nuts, beans and animal-source foods, is linked to greater nutrient adequacy. We developed a 'dietary gap assessment' to evaluate the degree to which a nation's food supply could support healthy diets at the population level. Design/Setting In the absence of global food-based dietary guidelines, we selected the Dietary Approaches to Stop Hypertension (DASH) diet as an example because there is evidence it prevents diet-related chronic disease and supports adequate micronutrient intakes. We used the DASH guidelines to shape a hypothetical 'healthy' diet for the test country of Cameroon. Food availability was estimated using FAO Food Balance Sheet data on country-level food supply. For each of the seven food groups in the 'healthy' diet, we calculated the difference between the estimated national supply (in kcal, edible portion only) and the target amounts. RESULTS: In Cameroon, dairy and other animal-source foods were not adequately available to meet healthy diet recommendations: the deficit was -365 kcal (-1527 kJ)/capita per d for dairy products and -185 kcal (-774 kJ)/capita per d for meat, poultry, fish and eggs. Adequacy of fruits and vegetables depended on food group categorization. When tubers and plantains were categorized as vegetables and fruits, respectively, supply nearly met recommendations. Categorizing tubers and plantains as starchy staples resulted in pronounced supply shortfalls: -109 kcal (-457 kJ)/capita per d for fruits and -94 kcal (-393 kJ)/capita per d for vegetables. CONCLUSIONS: The dietary gap assessment illustrates an approach for better understanding how food supply patterns need to change to achieve healthier dietary patterns.

Accessibility and Affordability of Supermarkets: Associations With the DASH Diet.

INTRODUCTION: It is unknown whether there is an interplay of affordability (economic accessibility) and proximity (geographic accessibility) of supermarkets in relation to having a Dietary Approaches to Stop Hypertension (DASH)-accordant diet. METHODS: Data (collected: 2005-2015, analyzed: 2016) were from the cross-sectional, population-based Fenland Study cohort: 9,274 adults aged 29-64 years, living in Cambridgeshire, United Kingdom. Dietary quality was evaluated using an index of DASH dietary accordance, based on recorded consumption of foods and beverages in a validated 130-item, semi-quantitative food frequency questionnaire. DASH accordance was defined as a DASH score in the top quintile. Dietary costs (£/day) were estimated by attributing a food price variable to the foods consumed according to the questionnaire. Individuals were classified as having low-, medium-, or high-cost diets. Supermarket affordability was determined based on the cost of a 101-item market basket. Distances between home address to the nearest supermarket (geographic accessibility) and nearest economically-appropriate supermarket (economic accessibility) were divided into tertiles. RESULTS: Higher-cost diets were more likely to be DASH-accordant. After adjustment for key demographics and exposure to other food outlets, individuals with lowest economic accessibility to supermarkets had lower odds of being DASH-accordant (OR=0.59, 95% CI=0.52, 0.68) than individuals with greatest economic accessibility. This association was stronger than with geographic accessibility alone (OR=0.85, 95% CI=0.74, 0.98). CONCLUSIONS: Results suggest that geographic and economic access to food should be taken into account when considering approaches to promote adherence to healthy diets for the prevention of cardiovascular diseases and other chronic disease.

Smoking status is inversely associated with overall diet quality: Findings from the ORISCAV-LUX study.

BACKGROUND & AIMS: Relationships between food consumption/nutrient intake and tobacco smoking have been described in the literature. However, little is known about the association between smoking and overall diet quality. This study examined the associations between eight diet quality indices, namely, the Diet Quality Index-International (DQI-I), Recommendation Compliance Index (RCI), Dietary Approach to Stop Hypertension (DASH) score, Energy Density Score (EDS), Dietary Diversity Score (DDS), Recommended Food Score (RFS), non-Recommended Food Score (non-RFS), and Dietary Inflammatory Index (DII), and smoking status with a focus on smoking intensity. METHODS: Analyses were based on a sample of 1352 participants in the Observation of Cardiovascular Risk Factors in Luxembourg (ORISCAV-LUX) survey, a nationwide population-based cross-sectional study of adults aged 18-69 years. Nutritional data from food frequency questionnaire (FFQ) were used to compute selected diet quality indices. Participants were classified as never smoker, former smoker (≥12 months cessation period), occasional or light smokers (≤1 cig/d), moderate smokers (≤20 cig/d) and heavy smokers (>20 cig/d). Descriptive and linear regression analyses were performed, after adjustment for several potential covariates. RESULTS: Compared to the other groups, heavy smokers had significantly higher prevalence of dyslipidemia (83%), obesity (34%), and elevated glycemic biomarkers. About 50% of former smokers had hypertension. Diet quality of heavy smokers was significantly poorer than those who never smoked independent of several socioeconomic, lifestyle, and biologic confounding factors (all p < 0.001). Heavy smokers were less compliant with national or international dietary recommendations, expressed by RCI, DQI-I, and RFS. In addition, they consumed a more pro-inflammatory diet, as expressed by higher DII scores (P < 0.001) and self-reported less dietary diversity in their food choices, as expressed by DDS. CONCLUSION: This study provides new evidence concerning an inverse relationship between the intensity of tobacco consumption and overall diet quality. The implication is that efforts aimed at tobacco control should target heavy smokers and intervention on smoking cessation should take into account diet quality of smokers and their nutritional habits, to increase effectiveness and relevance of public health messages.
