The hazards of urban life in late Stalinist Russia : health, hygiene, and living standards, 1943-1953
\"This is the first detailed study of the standard of living of ordinary Russians following World War II. It examines urban living conditions under the Stalinist regime with a focus on the key issues of sanitation, access to safe water supplies, personal hygiene and anti-epidemic controls, diet and nutrition, and infant mortality. Comparing five key industrial regions, it shows that living conditions still lagged some fifty years behind Western European norms. Yet, despite this, the book reveals that the years preceding Stalin's death saw dramatic improvements in mortality rates thanks to the application of rigorous public health controls and Western medical innovations. While tracing these changes, the book also analyzes the impact that the absence of an adequate urban infrastructure had on peoples' daily lives and on the relationship between the Stalinist regime and the Russian people and, finally, how the Soviet experience compared to that of earlier industrializing societies\"--Provided by publisher.

Understanding meal patterns: definitions, methodology and impact on nutrient intake and diet quality
Traditionally, nutrition research has focused on individual nutrients, and more recently dietary patterns. However, there has been relatively little focus on dietary intake at the level of a ‘meal’. The purpose of the present paper was to review the literature on adults' meal patterns, including how meal patterns have previously been defined and their associations with nutrient intakes and diet quality. For this narrative literature review, a comprehensive search of electronic databases was undertaken to identify studies in adults aged ≥ 19 years that have investigated meal patterns and their association with nutrient intakes and/or diet quality. To date, different approaches have been used to define meals with little investigation of how these definitions influence the characterisation of meal patterns. This review identified thirty-four and fourteen studies that have examined associations between adults' meals patterns, nutrient intakes and diet quality, respectively. Most studies defined meals using a participant-identified approach, but varied in the additional criteria used to determine individual meals, snacks and/or eating occasions. Studies also varied in the types of meal patterns, nutrients and diet quality indicators examined. The most consistent finding was an inverse association between skipping breakfast and diet quality. No consistent association was found for other meal patterns, and little research has examined how meal timing is associated with diet quality. In conclusion, an understanding of the influence of different meal definitions on the characterisation of meal patterns will facilitate the interpretation of the existing literature, and may provide guidance on the most appropriate definitions to use.

Review of Validated Methods to Evaluate Diet History in Diet Therapy and Counselling: An Overview and Analysis of Screeners Based on Food-Based Dietary Guidelines
Evidence-based dietetic practice calls for systematically developed assessment methods for nutritional assessment in dietetic counselling and therapy (DCT). Screeners can provide a quick and easy way to determine a client’s diet quality and contribute to quality assurance in DCT. The aim of this systematic review was to give a comparative overview of screeners based on national food-based dietary guidelines (FBDGs) and to derive recommendations for developing an FBDG-based screener for DCT. The literature search in PubMed (MEDLINE), embase and Web of Science was conducted between May and July 2022, and updated in March 2023, in accordance with the consensus-based standards for the selection of health measurement instruments (COSMIN). The analysis focused on characteristics of screener design and measurement properties for screener testing. In total, 13 studies on 11 screeners based on FBDGs were included; 7 screeners were targeted to DCT. The content and scoring of screeners were based on the corresponding national FBDGs. The validity and/or reliability of screeners were investigated in 11 studies; responsiveness was not tested for any screener and practicality was considered in all studies. Based on the screeners reviewed, a systematic rationale to develop, enhance and test screeners based on national FBDGs was established.

A critical review of predefined diet quality scores
The literature on predefined indexes of overall diet quality is reviewed. Their association with nutrient adequacy and health outcome is considered, but our primary interest is in the make-up of the scores. In total, twenty different indexes have been reviewed, four of which have gained most attention, and many others were based on those four. The various scores differ in many respects, such as the items included, the cut-off values used, and the exact method of scoring, indicating that many arbitrary choices have been made. Correlations in intake between dietary components may not be adequately addressed. In general, diet quality scores show an association with mortality or disease risk, but these relations are generally modest. Existing indexes do not predict morbidity or mortality significantly better than individual dietary factors. Although conclusions from the review may provide guidance in the construction of a diet quality score, it is questionable whether a dietary score can be obtained that is a much better predictor of health outcome.

Development of the Scores for Traditional and Modified Japanese Diets
Increasing attention is being paid to the role of diet quality in the prevention and management of non-communicable diseases. We developed a scoring system for the traditional Japanese diet and its modified version considering the dietary culture in Japan, dietary guidelines for the Japanese, and updated evidence for disease prevention. The traditional Japanese diet comprises white rice, miso soup, soybean products, vegetables, mushrooms, seaweeds, fish and shellfish, high-sodium foods, and green tea. In the modified Japanese diet, unprocessed or minimally refined rice and raw vegetables, milk and dairy products, and fruits were additionally considered, while salty food was reverse-scored. The cutoff for the intake frequency of each food/food group was determined with reference to a health survey of >12,000 workers. Among the participants in the validation study, we confirmed the nutritional gradient with increasing scores in the expected direction. The scores were closely correlated with the respondents’ backgrounds, including occupational factors. This simple scoring system can be used for diet quality assessments and epidemiological research.

Diet quality indices and their associations with health-related outcomes in children and adolescents: an updated systematic review
Background
To describe a-priori diet quality indices used in children and adolescents, appraise the validity and reliability of these indices, and synthesise evidence on the relationship between diet quality and physical and mental health, and growth-related outcomes.
Methods
Five electronic databases were searched until January 2019. An a-priori diet quality index was included if it applied a scoring structure to rate child or adolescent (aged 0–18-years) dietary intakes relative to dietary or nutrient guidelines. Diagnostic accuracy studies and prospective cohort studies reporting health outcomes were appraised using the Academy of Nutrition and Dietetics Quality Criteria Checklist.
Results
From 15,577 records screened, 128 unique paediatric diet quality indices were identified from 33 countries. Half of the indices’ scores rated both food and nutrient intakes (
n
= 65 indices). Some indices were age specific: infant (< 24-months;
n
= 8 indices), child (2–12-years;
n
= 16), adolescent (13–18 years;
n
= 8), and child/adolescent (
n
= 14). Thirty-seven indices evaluated for validity and/or reliability. Eleven of the 15 indices which investigated associations with prospective health outcomes reported significant results, such as improved IQ, quality of life, blood pressure, body composition, and prevalence of metabolic syndrome.
Conclusions
Research utilising diet quality indices in paediatric populations is rapidly expanding internationally. However, few indices have been evaluated for validity, reliability, or association with health outcomes. Further research is needed to determine the validity, reliability, and association with health of frequently utilised diet quality indices to ensure data generated by an index is useful, applicable, and relevant.

The association of global and prime diet quality scores with sperm quality parameters: a cross-sectional study
Background
Diet can directly affect the quality of semen. According to our knowledge, no study has assessed the relationship between the global diet quality score (GDQS) and the prime diet quality score (PDQS) with infertility. Therefore, the purpose of this study was to investigate the relationships between GDQS and PDQS and sperm quality parameters.
Methods
In the present cross-sectional study, 260 men with infertility were selected from a major infertility clinic in Isfahan Province, Iran. Four semen parameters were evaluated: semen volume, normal sperm morphology, sperm concentration, and total sperm motility. Also, a validated food frequency questionnaire (FFQ) comprising 168 items was employed to assess the food intake of participants. Moreover, logistic regression was used to evaluate the relationship between GDQS and PDQS with sperm parameters.
Results
The findings showed lower odds of abnormal sperm concentration associated with each unit increase in GDQS (odds ratio (OR) = 0.854, 95% confidence interval (CI): 0.764–0.954,
p
= 0.005), health-positive foods of GDQS (GDQS+) (OR = 0.816, 95% CI: 0.717–0.928,
p
= 0.002), PDQS (OR = 0.892, 95% CI: 0.814–0.978,
p
= 0.015), and healthy food groups of PDQS (PDQS+) (OR = 0.825, 95% CI: 0.734–0.926,
p
= 0.001).
Conclusions
The findings of this cross-sectional study suggest a potential association between adherence to a healthy and high-quality diet and higher sperm concentration among men with infertility. Further research, particularly well-designed prospective and interventional studies, is needed to better understand the temporal and causal relationships between diet quality and male reproductive health.

Looking Beyond Nutrients, How to Assess Diet Quality in an Inflammatory Bowel Disease Population—A Narrative Review
Background: Dietary assessment in inflammatory bowel disease (IBD) is moving away from individual food and nutrient analyses and towards dietary patterns (e.g., Mediterranean diet, Western diet) and diet quality assessment that are increasingly implicated in IBD onset and course. However, an IBD-specific diet quality index (DQI) does not exist. This review aimed to identify current DQIs and assess their suitability for an IBD population. Methods: MEDLINE and EmCare databases were systematically searched for a-priori, food-based DQI reflecting current dietary guidelines and/or nutrition science. Data extracted were adapted from optimal DQI criteria, including quality measures of adequacy, moderation, variety and balance and DQI evaluation. Results: Twenty-four DQI were identified. No DQI included all optimal DQI criteria. The Dietary Guideline Index 2013 (DGI-2013) most closely met the criteria, followed by the Dutch Healthy Diet Index-2015 (DHD-Index 2015), Planetary Health Diet Index (PHDI) and Healthy Eating Index for Australian Adults-2013 (HEIFA-2013). Most DQI assessed adequacy (22/24, 92%) and moderation (21/24, 88%), half assessed balance (12/24) while few assessed variety (8/24, 33%). Application of other optimal DQI criteria varied. Food frequency questionnaire (13/24) and 24 h diet recall (12/24) were the most common dietary assessment methods used. Most DQI (17/24, 71%) were validated; however, not for an IBD population. Few were evaluated for reliability (6/24) or reproducibility (1/24). Conclusions: No DQI meets all optimal criteria for an IBD-specific DQI. The DGI-2013 met the most criteria, followed by the DHD Index-2015, PHDI and HEIFA-2013 and may be most appropriate for an IBD population. An IBD-specific DQI is lacking and needed.

Diet cost and quality using the Healthy Eating Index-2015 in adults from urban and rural areas of Mexico
To assess the association between diet cost and quality by place of residence.
We analysed cross-sectional data of the National Health and Nutrition Survey-2012. Diet cost was estimated by linking dietary data, obtained from a 7-d SFFQ, with municipality food prices, which were derived from a national expenditure survey. Diet quality was assessed using the Healthy Eating Index-2015 (HEI-2015). Association between quintiles of diet cost and HEI-2015 was assessed using linear regression analysis.
Mexico.
2438 adults (18-59 years).
Diet cost was positively associated with diet quality (HEI-2015) in urban but not in rural areas. Compared with quintile (Q1) of cost, the increment in diet quality score was 1·17 (95 % CI -0·06, 4·33) for Q2, 2·14 (95 % CI -0·06, 4·33) for Q3, 4·70 (95 % CI 2·62, 6·79) for Q4 and 6·34 (95 % CI 4·20, 8·49) for Q5 (
-trend < 0·001). Individuals in rural
. urban areas on average have higher quality diets at lower cost with higher intakes of whole grains and beans and lower intakes of Na, added sugars and saturated fats. Living in the South, being indigenous and having low socio-economic status were also associated with higher quality diets.
Diet cost was positively associated with diet quality, but only in urban areas. Further studies are needed to understand the relation between diet cost and quality in rural areas. To improve overall diet quality in Mexico, strategies that aim to reduce the cost of high-quality diets should consider the heterogeneity by place of residence.

Quality and validity of diet quality indices for use in Australian contexts: a systematic review
Diet quality indices (DQIs) are tools used to evaluate the overall diet quality against dietary guidelines or known healthy dietary patterns. This review aimed to evaluate DQIs and their validation processes to facilitate decision making in the selection of appropriate DQI for use in Australian contexts. A search of CINAHL, PubMed and Scopus electronic databases was conducted for studies published between January 2010 and May 2020, which validated a DQI, measuring > 1 dimension of diet quality (adequacy, balance, moderation, variety) and was applicable to the Australian context. Data on constructs, scoring, weighting and validation methods (construct validity, criterion validity, reliability and reproducibility) were extracted and summarised. The quality of the validation process was evaluated using COnsensus-based Standards for the selection of health Measurement INstruments Risk of Bias and Joanna Briggs Appraisal checklists. The review identified twenty-seven indices measuring adherence to: national dietary guidelines (n 13), Mediterranean Diet (n 8) and specific population recommendations and chronic disease risk (n 6). Extensiveness of the validation process varied widely across and within categories. Construct validity was the most strongly assessed measurement property, while evaluation of measurement error was frequently inadequate. DQIs should capture multiple dimensions of diet quality, possess a reliable scoring system and demonstrate adequate evidence in their validation framework to support use in the intended context. Researchers need to understand the limitations of newly developed DQIs and interpret results in view of the validation evidence. Future research on DQIs is indicated to improve evaluation of measurement error, reproducibility and reliability.
