Dietary diversity, an important component of diet quality, is associated with an increased probability of adequate micronutrient intake. Women of childbearing age (WCA) are particularly vulnerable to micronutrient inadequacy. The Minimum Dietary Diversity for Women (MDD-W) has been used widely as a proxy measurement of micronutrient adequacy. This study aimed to assess the association between MDD-W and nutrients adequacy among WCA of eight Latin American countries. Nutrient intakes from 3704 WCA were analyzed with two 24-hour dietary recalls. Dietary diversity was calculated based on ten food groups with a cut-off point of intake ≥5 groups. The mean dietary diversity score was 4.72 points, and 57.7% of WCA achieved MDD-W. Vitamin D and E showed a mean Nutrient Adequacy Ratio (NAR) of 0.03 and 0.38, respectively. WCA with a diverse diet (MDD-W > 5) reported a significantly higher intake of most micronutrients and healthy food groups with less consumption of red and processed meats and sugar-sweetened beverages. MDD-W was significantly associated with the mean adequacy ratio (MAR) of 18 micronutrients evaluated. Nevertheless, even those women with a diverse diet fell short of meeting the Estimated Average Requirements (EAR) for vitamins D and E. MDD-W is an appropriate tool to evaluate micronutrients adequacy in WCA from Latin America, showing that women who achieved the MDD-W reported higher adequacy ratios for most micronutrients and an overall healthier diet.

AbstractObjectiveTo assess whether a food variety score (FVS) and/or a dietary diversity score (DDS) are good indicators of nutrient adequacy of the diet of South African children.MethodsSecondary data analyses were undertaken with nationally representative data of 1–8-year-old children (n = 2200) studied in the National Food Consumption Study in 1999. An average FVS (mean number of different food items consumed from all possible items eaten) and DDS (mean number of food groups out of nine possible groups) were calculated. A nutrient adequacy ratio (NAR) is the ratio of a subject's nutrient intake to the estimated average requirement calculated using the Food and Agriculture Organization/World Health Organization (2002) recommended nutrient intakes for children. The mean adequacy ratio (MAR) was calculated as the sum of NARs for all evaluated nutrients divided by the number of nutrients evaluated, expressed as a percentage. MAR was used as a composite indicator for micronutrient adequacy. Pearson correlation coefficients between FVS, DDS and MAR were calculated and also evaluated for sensitivity and specificity, with MAR taken as the ideal standard of adequate intake. The relationships between MAR and DDS and between anthropometric Z-scores and DDS were also evaluated.ResultsThe children had a mean FVS of 5.5 (standard deviation (SD) 2.5) and a mean DDS of 3.6 (SD 1.4). The mean MAR (ideal = 100%) was 50%, and was lowest (45%) in the 7–8-year-old group. The items with the highest frequency of consumption were from the cereal, roots and tuber group (99.6%), followed by the ‘other group’ (87.6%) comprising items such as tea, sugar, jam and sweets. The dairy group was consumed by 55.8%, meat group by 54.1%, fats by 38.9%, other vegetables by 30.8%, vitamin-A-rich by 23.8%, other fruit by 22%, legumes and nuts by 19.7% and eggs by 13.3%. There was a high correlation between MAR and both FVS (r = 0.726; P < 0.0001) and DDS (r = 0.657; P < 0.0001), indicating that either FVS or DDS can be used as an indicator of the micronutrient adequacy of the diet. Furthermore, MAR, DDS and FVS showed significant correlations with height-for-age and weight-for-age Z-scores, indicating a strong relationship between dietary diversity and indicators of child growth. A DDS of 4 and an FVS of 6 were shown to be the best indicators of MAR less than 50%, since they provided the best sensitivity and specificity.ConclusionEither FVS or DDS can be used as a simple and quick indicator of the micronutrient adequacy of the diet.

Dietary Diversity, with foods from all food groups is necessary to meet the requirements for essential nutrients which lead to good health. This study examines whether different dietary diversity indices have relationship with the nutritional status of school children aged 6 to 12 years, in two different regions of India: Wardha district, Maharashtra and Koraput district, Odisha. Dietary diversity was calculated using three methods: Individual food scores calculated using 24 hour diet recall (FS<sub>24hr</sub>) data; household dietary diversity using Berry's index (DDI) and food scores calculated using food frequency data (FS<sub>FFQ</sub>). Anthropometric indices were used to assess the nutritional status of school aged children. The Nutrient Adequacy Ratio (NAR) and the Mean Adequacy Ratio (MAR) were calculated as indicators of nutrient adequacy. The relationship between NAR, MAR and three different diversity indices, dietary diversity and anthropometric indices were analyzed. Overall, 38% of 6 to 12 year school aged children were found to be undernourished. The NAR was &lt;70% for all nutrients except protein, energy, thiamine and niacin and MAR was found to be &lt;70% of requirement with mean of 60.5% in both locations. The dietary diversity was found to be relatively better in Wardha when compared with Koraput. The mean diversity indices in both the locations were FS<sub>24hr</sub> 7.56, DDI 89 and FS<sub>FFQ</sub> 62.9. Overall most of the nutrient adequacy and mean adequacy were correlated with all three dietary diversity indices when both locations were studied together. However all three dietary diversity indices failed to show any relationship with nutritional status of school children aged 6-12 years from both locations taken together.

Background: Nephrolithiasis is a global health problem that is growing exponentially in the developed and developing countries. This study aimed to determine the dietary diversity score (DDS) and its association with nutrient adequacy in patients with calcium oxalate kidney stone. Methods: The present cross-sectional study was conducted on 276 male patients with calcium oxalate kidney stone. The validity and reliability of dietary intake was assessed by the 147-item food frequency questionnaire. Based on the USDA Food Guide Pyramid, the five food groups (grains, vegetables, fruits, meats, and dairy products) were used to determine the DDS. The nutrient adequacy ratio and the mean adequacy ratio were calculated using the Recommended International Standards. Results: The mean of the body mass index of the participants was 27.49 ± 4.01 kg/m2. Mean of the total DDS was also 5.62 ± 1.29. Participants in the highest DDS tertile had higher energy and fat intake than those in the lowest tertile (P-trend < 0.05). The highest and lowest DDS were observed in the fruit and vegetable groups: 1.58 ± 0.53 and 0.91 ± 0.29, respectively. The total DDS had a positive correlation with the adequacy of energy intake and macronutrients including protein and fats (P < 0.05). Furthermore, a significant positive correlation was found between the total DDS and the mean adequacy ratio (P < 0.01, r = 0.2). Conclusion: The findings showed that patients with calcium oxalate kidney stone did not have an appropriate level of total DDS (DDS < 6), indicating that they did not receive diverse nutrients.

Micronutrient inadequacy remains a nutritional problem in Chinese children. However, the associations between dietary diversity and inadequate micronutrient intake have not been extensively studied. A total of 2012 children aged 3–17 years from the China Health and Nutrition Survey were included for analysis. Dietary diversity score (DDS) and food variety scores (FVS) were assessed based on three 24-h recall periods. The nutrient adequacy ratio (NAR) was used to determine the micronutrient adequacy of the diet. The mean adequacy ratio (MAR, %) was defined as the sum of each NAR divided by the number of involved micronutrients. Overall micronutrient inadequacy (OMI) was defined as having a MAR below 0.75. Micronutrient inadequacy was defined as the proportion of individuals whose nutrient intake was less than the estimated average requirement. After adjustment confounders, DDS and FVSs were positively associated with MAR and NAR of most nutrients except sodium (p < 0.05). A higher DDS was negatively associated with the prevalence of inadequate intake of vitamin A, riboflavin, vitamin C, iron, zinc, selenium, niacin, phosphorus, magnesium and OMI. Similar results were found for FVSs. In conclusion, this study indicates that poor dietary diversity and food variety in Chinese children are directly associated with inadequate micronutrient intake.

SummaryDietary diversity is associated with household or individual food availability and intake of nutrients from different food groups and is an important component of nutritional outcome. This study examined the Nutrient Adequacy Ratio (NAR) and the Mean Adequacy Ratio (MAR) of three dietary diversity indices and their relationship with the nutritional status of adolescents and adults in rural regions of two states in India, Wardha district in Maharashtra and Koraput district in Odisha, in 2014. Individual dietary diversity was calculated using 24-hour diet recall (FS24hr) data and household dietary diversity was measured with food frequency data using Berry’s index (DDI) and food scores (FSFFQ). The nutritional status of individuals was assessed using anthropometric indices. The diets in both locations were cereal dominated. It was observed that 51% of adolescent boys and 27% of adolescent girls had ‘thinness’ and stunting. The prevalence of undernutrition was higher among adult women (48%) than adult men (36%). The mean diversity indices were FS24hrof 8, DDI of 89–90 and FSFFQof 64–66 in the two locations. The FS24hrwas found to be positively correlated with the NAR of all nutrients while DDI and FSFFQwere correlated with seven and six nutrients, respectively. The DDI and FS24hrshowed an association with MAR if the two locations were combined together. Sensitivity and specificity analysis showed that FS24hrgave more true positives than false positives and the area under the Receiver Operating Characteristic curve was 0.68, implying that this measure truly differentiates individuals having low dietary diversity with low MAR from those with low dietary diversity and a high MAR. All three measures of dietary diversity showed a linear association with the nutritional outcomes of adults, while in the adolescent group only DDI showed a relationship. It is concluded that 24-hour diet recall is a good measure for studying the relationship between dietary diversity and nutritional status in adults.

Introdução: O tromboembolismo venoso (TEV) incide em mulheres de idade fértil e a identificação dos fatores de risco é ponto crucial para sua prevenção. Objetivos: Identificar e correlacionar os fatores de risco mais comuns para o desencadeamento de TEV em mulheres de 14 a 50 anos. Métodos: Analisadas 30 mulheres com diagnóstico recente de trombose venosa profunda (TVP) de membros inferiores por meio de ultrassonografia com Doppler colorido e de seus prontuários, no período de julho de 2011 a julho de 2016. Os fatores de risco foram descritos em proporções e comparados através de teste exato de Fisher. Resultados: A média de idade foi de 37,4 anos. O índice de massa corpórea médio foi de 27,4 kg/m2 e a média de gestações foi de 2,3 por paciente. Setenta por cento apresentaram TVP, e a prevalência em ambos os membros foi igual. Cirurgias recentes, história familiar de TEV, doenças associadas e uso de contraceptivos orais (CO) foram os mais prevalentes na população estudada (53,8%, 42,3%, 42,3% e 38,5%, respectivamente). Uso de CO, cirurgia recente e varizes de grosso calibre foram os fatores mais relacionados à recorrência da trombose (p<0,05). Conclusão: Pode-se concluir que a presença de varizes, cirurgia recente e história familiar são os fatores de risco mais associados à presença de TVP em mulheres de idade fértil. Uso de CO, cirurgia recente e presença de varizes são os fatores de risco mais estatisticamente relacionados à recorrência da TVP.Palavras-Chave: Tromboembolia venosa; Saúde da mulher; Fatores de riscoABSTRACTIntroduction: Venous thromboembolism (VTE) affects women of childbearing age and the identification of risk factors is a key point for preventing its development. Aims: To identify and correlate the most common risk factors for the development of VTE in women aged 14-50 years. Meth-ods: We analyzed 30 women with recent diagnosis of deep venous thrombosis (DVT) of the lower limbs using Doppler color ultrasonography and their medical records from July 2011 to July 2016. Risk factors were described as proportions and compared using Fisher’s exact test. Re-sults: The mean age was 37.4 years. The mean body mass index was 27.4 kg/m2 and the mean gestation rate was 2.3 per pa-tient. Seventy percent presented DVT, and the prevalence in both limbs was the same. Recent surgeries, familiar historical of VTE, associated diseases and use of oral contraceptives (OC) were the most preva-lent factors in the studied population (53.8%, 42.3%, 42.3% and 38.5%, respec-tively). Use of OC, recent surgery and varicose veins were the factors most related to recurrence of thrombosis (p<0.05). Conclusion: It can be concluded that the presence of varicose veins, recent surgery and family history are the risk factors that are most associated with the presence of DVT in women of childbearing age. Use of OC, recent surgery and presence of varicose veins are the risk factors more statistically related to recurrence of DVT.Keywords: Venous thromboembolism; Women’s health; Risk factors

AbstractObjectiveDiet in adolescence is important not only because of adolescents’ rapid growth but also due to its influence on future chronic diseases. On the other hand, dietary quality indices are noteworthy and useful approaches to evaluate dietary intakes. Thus the present study was conducted to assess dietary quality indices in adolescents.DesignCross-sectional.SettingsThe data were collected from schools in Isfahan, Iran.SubjectsFemale students (n 265) aged 11–13 years were enrolled using systematic cluster-random sampling in Isfahan (Iran). Dietary intakes were assessed by a validated FFQ. Diet quality indices including dietary diversity score (DDS), the Healthy Eating Index (HEI) and mean adequacy ratio (MAR) across ten nutrients were calculated.ResultsMean DDS, HEI score and MAR were 6·15 (sd 1·61) out of 10 points, 63·90 (sd 19·86) out of 100 points and 1·32 (sd 0·61), respectively. Mean nutrient adequacy ratio of all nutrients was above 1 except for vitamin D (0·53 (sd 0·51)). Those in the highest tertile of DDS had the most favourable anthropometric variables in comparison to the lowest tertile. There were no significant associations between HEI score and BMI, central or abdominal obesity and blood pressure. Those in the highest tertile of MAR had higher BMI, waist circumference and hip circumference.ConclusionsDiet quality of Isfahani adolescents needs improvement. It may imply the necessity of implementing nutritional instructive policies in this age group and their parents.

We examined the intra- and interindividual variability in selected measures of overall diet quality in relation to socio-demographic, lifestyle, and health-related characteristics. Three days of dietary data from the Continuing Survey of Food Intakes by Individuals (CSFII), 1989–91 (7841 respondents, 3337 men and 4504 women, aged ≥ 19 years), were examined. Measures of overall diet quality were: 1. the Dietary Diversity Score (DDS), a measure of variety among the major food groups; 2. the Overall Variety Score (OVS), examined the number of nutrient-dense foods reported; and 3. the Nutrient Adequacy Score (NAS100), evaluated the number of nutrients consumed at least at the level of the RDA from a total of 11. The ratio of intra- to interindividual variance for DDS, OVS, and NAS100 was 1.66, 1.09, and 1.21, respectively, indicating higher intraindividual variability relative to interindividual variability. For each of the three scores, gender, income, education, and smoking were associated with greater intraindividual variability; however, age, and special diet status were associated with lower variability. Thus, the reliability of a given dietary assessment protocol for evaluating “usual” diet quality is likely to vary by the socio-demographic and lifestyle characteristics of the study population.

Background: Lack of dietary diversity in complementary feeding contributes to nutrient gaps leading to undernutrition. Food-based strategies have been successfully used to enrich the complementary diets of infants and young children. However, context-specific recommendations based on an objective diet optimization is needed to formulate sound and practical nutritional guidelines. Objectives: The present study aimed to identify problem nutrients in complementary diets and formulate complementary feeding recommendations (CFRs) using linear programming analysis for children aged 6 to 23 months in the rural Philippines. Methods: A cross-sectional survey was conducted in the municipality of Mercedes, Philippines. Dietary intakes of breastfed children 6 to 8, 9 to 11, and 12 to 23 months of age (n = 297) were assessed using a multipass 24-hour recall method with 7-day food consumption frequency. A linear programming tool was used to identify the recommended nutrient intakes that could not be met within the existing local food patterns and develop CFRs that would best fulfil nutrient adequacy for 11 modelled micronutrients. Results: Problem nutrients in the current diets were iron and calcium in any age-group, zinc for 6 to 8 and 9 to 11 months old, and thiamine and folate for 12 to 23 months old children. Adoption of CFRs with 4 to 5 food groups in the diet would ensure the adequacy of 7 to 8 nutrients, depending on the age-group. Conclusion: Within the boundaries of local dietary patterns, adequacy for most nutrients could be achieved by promoting realistic servings of nutrient-dense foods and food groups. The linear programming results provide an evidence-based strategy in designing interventions to improve the quality of Filipino complementary diets.
