Nutrient Patterns

Dietary pattern analyses allow assessment of the diet as a whole. Limited studies include both a priori and a posteriori dietary pattern analyses. This study aimed to explore the diet of pregnant women in urban South Africa through both a priori and a posteriori dietary pattern analyses and associated maternal and household factors. Dietary data were collected during early pregnancy using a quantified food frequency questionnaire from 250 pregnant women enrolled in the Nutrition During Pregnancy and Early Development (NuPED) cohort. A priori dietary patterns were determined using the Diet Quality Index-International (DQI-I), and a posteriori nutrient patterns using exploratory factor analysis. Based on the DQI-I, the study population followed a borderline low-quality diet. Three a posteriori nutrient patterns were identified: Pattern 1 “plant protein, iron, thiamine, and folic acid”; pattern 2 “animal protein, copper, vitamin A, and vitamin B12”; pattern 3 “fatty acids and sodium”. Pattern 1 was associated with higher dietary quality (p < 0.001), lower maternal educational level (p = 0.03) and socioeconomic status (p < 0.001). Pattern 3 was significantly associated with lower dietary quality. The low dietary quality among pregnant women residing in urban South Africa should be addressed to ensure optimal maternal and offspring health outcomes.

Diet Score

Background: Previous studies have investigated the association of dietary patterns with risk of diabetes, but have not compared a priori and a posteriori dietary scores in the same diverse population. The objective of this study was to evaluate a priori and a posteriori dietary patterns associations with incident diabetes in the REGARDS study. Methods: This study included 8,875 Black and White adults with available dietary data, without diabetes (defined as fasting glucose>=126 mg/dL, random glucose>=200 mg/dL, or use of diabetes medications) at baseline (2003-2007), and with follow-up (2013-2016) status of diabetes. Dietary patterns were examined by quintile and included a posteriori Plant-based and Southern, as well as a priori scores of Mediterranean Diet Score, Dietary Approaches to Stop Hypertension (DASH) Diet Score, Dietary Inflammatory Index (DII) and Dietary Inflammation Score (DIS). Modified Poisson regression was used to obtain risk ratios for incident diabetes with models adjusted for total energy intake, demographics, and lifestyle factors. Results: The mean (SD) age at baseline was 63.2 (8.5) years, 27.1% were Black, 56.2% were female, and 11.7% had incident diabetes at follow-up. Adherence to the Southern dietary pattern was positively associated with incident diabetes for all models (figure). After adjustment for demographic factors, the highest quintiles of DII and DIS were associated with incident diabetes and the highest quintiles of DASH scores were protective of development of incident diabetes. Conclusion: The Southern dietary pattern derived in REGARDS showed the strongest association with incident diabetes of all the dietary scores and of the a priori scores the DIS showed the strongest association with incident diabetes. The lack of association in adjusted models with the Mediterranean Diet and Plant-based pattern show these scores to be less pertinent. The DIS demonstrates food based dietary inflammation as one of the potential pathways for incident diabetes.

Healthy Dietary Pattern

Abstract Objectives Diet is an important lifestyle factor that may prevent or slow the onset and progression of neurodegeneration. Recent studies suggest that adherence to a healthy dietary pattern is associated with reduced risk of cognitive decline. Few studies have examined the relationships between dietary patterns and risk of clinical neurodegenerative disease outcomes. In this meta-analysis, we examined the associations between overall dietary patterns, assessed a priori and a posteriori, and risk of major neurodegenerative disease including dementia, Alzheimer's disease, and Parkinson's disease. Methods We systematically searched in the PubMed, Web of Science, and Cumulative Index for Nursing and Allied Health databases starting from 1981 to October 10, 2018. Observational cohort studies published in English with prospective and case-control designs were included. Diet assessment approaches (a priori or a posteriori) were utilized to assist in determining whether the exposure was dietary pattern score or diet quality. Generic inverse variance method was used to calculate the pooled risk ratios and 95% confidence intervals (CIs) among the highest versus the lowest diet quality/dietary pattern score groups in random effect models. Results Seventeen studies with 173,283 participants were identified. Various diet quality indexes or dietary pattern scores, such as the Healthy Eating Index, the Mediterranean diet score, and dietary pattern scores generated by principal component analysis or reduced rank regression, were used among studies. Our meta-analysis of cohorts showed significant associations between adherence to high diet quality or healthy dietary pattern and lower risk of dementia (pooled risk ratio = 0.70; 95% CI: 0.56-0.86) and Parkinson's disease (pooled risk ratio = 0.72; 95% CI: 0.54-0.97) relative to those with low diet quality or unhealthy dietary pattern. Conclusions Adherence to high diet quality or healthy dietary pattern may provide protective effects on risk of neurodegenerative diseases. Additional observational studies and randomized controlled trials are needed to address our study limitations and provide further evidence about the role of a poor diet on the development and progression of neurodegenerative diseases as well as the benefits of a healthy diet on the prevention of major neurodegenerative diseases.

The aim of this study was to identify dietary patterns in pregnant women and to assess the relationships between sociodemographic, lifestyle-related, and pregnancy-related factors. This is a descriptive, correlational study involving 306 pregnant women in Melilla (Spain) in any trimester of pregnancy. A validated food frequency questionnaire was used. Dietary patterns were determined via exploratory factor analysis and ordinal logistic regression using the proportional odds model. Three dietary patterns were identified: Western, mixed, and prudent. Sociodemographic, lifestyle-related, and pregnancy-related factors influencing dietary quality were established. The Western dietary pattern was considered the least recommended despite being the most common among women who live in Melilla (p = 0.03), are Christian (p = 0.01), are primiparous women (p < 0.001), and are in their first or second trimester (p = 0.02). Unemployed pregnant women were also more likely to have a less healthy dietary pattern (β = −0.716; p = 0.040). The prudent dietary pattern, the healthiest of the three, was most commonly observed among Muslim women (p = 0.01), women with more than two children (p < 0.001), and women in the third trimester of pregnancy (p = 0.02). Pregnant women who engaged in no physical activity or a low level of physical activity displayed a mixed pattern (p < 0.001). This study provides evidence on the factors influencing dietary patterns during pregnancy and suggests that more specific nutrition programmes should be developed to improve the nutritional status of pregnant women.

AbstractThe metabolic syndrome (MetS) is a key indicator of two main causes of death worldwide: CVD and diabetes. The present paper aimed to perform a review of the population-based research on the association of dietary patterns and the MetS in terms of methodology and findings. For the purpose of the present study, a scoping literature review was conducted using MEDLINE and EMBASE databases and hand searching in Google Scholar. Thirty-nine population-based studies were selected. Most of these studies used the factor analysis method and the a priori dietary approach, which had been initially extracted via a posteriori methods such as using the Mediterranean dietary pattern. The main finding was that following the Mediterranean or similar ‘healthy’ pattern reduced risk of the MetS, while following a ‘Western’ pattern increased risk of the MetS. The methodological approach in determining the dietary pattern of a population, whether a priori or a posteriori, should be chosen based on the purpose of the research. Overall, evidence suggests a diet based on the components of the Mediterranean diet and the avoidance of the ‘Western’ diet can aid in preventing the MetS.

Bone Mineral Status

Studies of individual nutrients or foods have revealed much about dietary influences on bone. Multiple food or nutrient approaches, such as dietary pattern analysis, could offer further insight but research is limited and largely confined to older adults. We examined the relationship between dietary patterns, obtained by a posteriori and a priori methods, and bone mineral status (BMS; collective term for bone mineral content (BMC) and bone mineral density (BMD)) in young adults (20–25 years; n 489). Diet was assessed by 7 d diet history and BMD and BMC were determined at the lumbar spine and femoral neck (FN). A posteriori dietary patterns were derived using principal component analysis (PCA) and three a priori dietary quality scores were applied (dietary diversity score (DDS), nutritional risk score and Mediterranean diet score). For the PCA-derived dietary patterns, women in the top compared to the bottom fifth of the ‘Nuts and Meat’ pattern had greater FN BMD by 0·074 g/cm2 (P = 0·049) and FN BMC by 0·40 g (P = 0·034) after adjustment for confounders. Similarly, men in the top compared to the bottom fifth of the ‘Refined’ pattern had lower FN BMC by 0·41 g (P = 0·049). For the a priori DDS, women in the top compared to the bottom third had lower FN BMD by 0·05 g/cm2 after adjustments (P = 0·052), but no other relationships with BMS were identified. In conclusion, adherence to a ‘Nuts and Meat’ dietary pattern may be associated with greater BMS in young women and a ‘Refined’ dietary pattern may be detrimental for bone health in young men.

Several epidemiologic studies have shown an association between Gestational Weight Gain (GWG) and offspring complications. The GWG is directly linked to maternal dietary intake and women’s nutritional status during pregnancy. The aim of this study was (1) to assess, in a sample of Spanish pregnant women, the association between maternal dietary patterns and GWG and (2) to assess maternal dietary patterns and nutrient adequate intake according to GWG. A retrospective study was conducted in a sample of 503 adult pregnant women in five hospitals in Eastern Andalusia (Spain). Data on demographic characteristics, anthropometric values, and dietary intake were collected from clinical records by trained midwives. Usual food intake was gathered through a validated Food Frequency Questionnaire (FFQ), and dietary patterns were obtained by principal component analysis. Nutrient adequacy was defined according to European dietary intake recommendations for pregnant women. Regression models adjusted by confounding factors were constructed to study the association between maternal dietary pattern and GWG, and maternal dietary patterns and nutritional adequacy. A negative association was found between GWG and the Mediterranean dietary pattern (crude β = −0.06, 95% CI: −0.11, −0.04). Independent of maternal dietary pattern, nutrient adequacy of dietary fiber, vitamin B9, D, E, and iodine was related to a Mediterranean dietary pattern (p < 0.05). A Mediterranean dietary pattern is related to lower GWG and better nutrient adequacy. The promotion of healthy dietary behavior consistent with the general advice promoted by the Mediterranean Diet (based on legumes, vegetables, nuts, olive oil, and whole cereals) will offer healthful, sustainable, and practical strategies to control GWG and ensure adequate nutrient intake during pregnancy.

The purpose of the present study was to conduct a systematic review of the literature on the value of the methods used to assess dietary patterns for measuring nutrient intake adequacy in the population. Systematic review on Pubmed database up to April 2008. The search included specific key words and MeSH terms. No language limit was set. Only studies that compared food patterns with nutrient intake adequacy or nutrient biomarkers were included in the analysis. The search resulted in 1504 articles. The inclusion and exclusion criteria limited the selection to thirty articles. Nineteen studies evaluated the usefulness of the dietary patterns, eithera prioridefined (thirteen studies), or defined by factor analysis (four studies) or by cluster analysis (two studies), but only nine of them tested their validity (foura prioridefined and foura posterioridefined). Diet indices showed moderate to good validity results for measuring the adequacy of intakes for α-carotene, β-carotene, vitamin C, vitamin B6, Ca, folic acid, Fe and Mg. The factor analysis approach showed moderate to good validity correlations with the adequacy of intake of α-carotene, β-carotene, lutein, lycopene, vitamin C, vitamin B6and folic acid. Vitamin B12and vitamin E are the micronutrients with less probability of being adequately assessed with dietary patternsa prioriora posterioridefined. Diet indices are tools with fair to moderate validity to assess micronutrient intake adequacy.

AbstractObjectiveObservational studies reported potential associations between different dietary patterns and the risk of metabolic syndrome (MetS); however, a consistent perspective has not been established to date. The current systematic review and meta-analysis aimed to evaluate the relationship between a posteriori dietary patterns and MetS by pooling available data.DesignMEDLINE and EMBASE databases were searched for relevant articles published up to July 2015 with no time restriction and with English language restriction. Two independent reviewers completed study selection and data extraction. Random-effects models (DerSimonian–Laird method) were used to pool effect sizes of eligible studies. The potential sources of heterogeneity were assessed using the I2 statistic.ResultsNineteen papers that identified dietary patterns using an a posteriori method were selected and included in the meta-analysis. The ‘Healthy/Prudent’ dietary pattern was inversely associated with risk of MetS (OR=0·89; 95 % CI 0·84, 0·94, P=0·002). In contrast, the ‘Unhealthy/Western’ dietary pattern had a significant positive association with risk of MetS (OR=1·16; 95 % CI 1·11, 1·22, P<0·001).ConclusionsOur findings provide evidence that greater adherence to a healthy/prudent dietary pattern is associated with a lower risk of MetS, while an unhealthy/Western dietary pattern is associated with increased risk of MetS. These data suggest that a diet based on healthy food choices is also beneficial for prevention of MetS.
