“…We found that participants in later pregnancy had a relatively higher overall diet quality compared to those in early pregnancy, which may be related to the stress of pregnancy. A cohort study from the FUDAN School of Public Health, which included 2634 participants, found that increased pregnancy-speci c stress in the middle and third trimesters may motivate pregnant women to follow a healthy balanced diet, and thus, equip them with more nutritional knowledge compared to novices in their rst trimester, which was thought as the weak association with poor birth outcomes in previous studies [24,25]. Compared to the chronic stress experienced during early pregnancy, the stress in the later trimesters is acute stress, characterized by increased blood sugar and poor appetite, which lure pregnant women to choose food that stimulates their appetite to meet their nutritional needs prior to labor [26,27].…”

Background: Good dietary quality among pregnant women is critical for maternal and fetal health. Comprehensive assessments of large representative samples are lacking. Methods: Pregnant women were enrolled using a multistage, stratified, random-sampling method in Shanghai. We used a personal food frequency questionnaire and a household condiment weighing method for dietary assessments. Participants’ scores on the China Healthy Diet Index (CHDI) were analyzed to evaluate diet quality.Results: Significant differences in the median daily intake of almost all food types were found across all trimesters, and all food types were found across all residential areas (urban, suburban and rural). Significant differences were found in the median total CHDI scores across trimesters, and on all CHID components, except whole grains, dry beans and tubers, across all residential areas; 13.7% of participants scored below 60 points, indicating “poor” dietary quality. Significant differences in CHDI scores were found across trimesters and residential areas. Participants in early and middle pregnancy had lower scores than those in late pregnancy. Women in urban areas had higher scores than those in suburban and rural areas.Conclusions: Pregnant women living in coastal areas of China suffer from an unbalanced diet of average quality. Pregnant women in the early and middle stages of pregnancy had worse scores than those in the late stage, while suburban and rural women had worse scores than urban women.

Dietary patterns and relative expression levels of PPAR-γ, VEGF-A and HIF-1α genes in benign breast diseases: case–control and consecutive case-series designs

Abstract We aimed to study dietary patterns in association with the relative expression levels of PPAR-γ, vascular endothelial growth factor-A (VEGF-A) and hypoxia-inducible factor-1α (HIF-1α) in women with benign breast disease (BBD). The study design was combinative, included a case-series and case–control compartments. Initially, eligible BBD patients (n 77, aged 19–52 years old) were recruited at Nour-Nejat hospital, Tabriz, Iran (2012–2014). A hospital-based group of healthy controls was matched for age (n 231, aged 20–63 years old) and sex. Dietary data were collected using a valid 136-item FFQ. Principal component analysis generated two main components (Kaiser–Meyer–Olkin = 0·684), including a Healthy pattern (whole bread, fruits, vegetables, vegetable oils, legumes, spices, seafood, low-fat meat, skinless poultry, low-fat dairy products, nuts and seeds) and a Western pattern (starchy foods, high-fat meat and poultry, high-fat dairy products, hydrogenated fat, fast food, salt and sweets). High adherence to the Western pattern increased the risk of BBD (ORadj 5·59; 95 % CI 2·06, 15·10; P < 0·01), whereas high intake of the Healthy pattern was associated with a 74 % lower risk of BBD (95 % CI 0·08, 0·81; P < 0·05). In the BBD population, the Western pattern was correlated with over-expression of HIF-1α (radj 0·309, P < 0·05). There were inverse correlations between the Healthy pattern and expressions of PPAR-γ (radj −0·338, P < 0·05), HIF-1α (radj −0·340, P < 0·05) and VEGF-A (radj −0·286, P < 0·05). In conclusion, new findings suggested that the Healthy pattern was associated inversely with the risk of BBD, and this could be correlated with down-regulation of PPAR-γ, VEGF-A and HIF-1α genes, which might hold promise to preclude BBD of malignant pathological transformation.

Abstract Background: Diet-based recommendations can be developed for preventing and treating non-alcoholic fatty liver disease (NAFLD) after investigating the effects of whole diets on NAFLD. The aim of this study was to identify major dietary patterns and their association with the risk of NAFLD.Methods: A total of 244 individuals (122 NAFLD patients and 122 controls) participated in this case-control study. The NAFLD patients were diagnosed by a gastroenterologist. The participants' dietary intake data were collected using a 147-item semi-quantitive food frequency questionnaire and major dietary patterns were identified by principal component analysis. Adherence to dietary patterns was divided into tertiles and its association with odds of NAFLD was investigated by multivariate logistic regression. Results: The results showed four major dietary patterns, among which adherence to the "ordinary pattern" was positively associated with NAFLD risk. After adjusting for all confounding factors, individuals in the highest tertile of "ordinary pattern" exhibited a significantly elevated risk of NAFLD compared to the lowest tertile (OR= 3.74, 95%CI= 1.23-11.42, P trend<0.001). As well as, Individuals in the second and third tertiles of the "traditional pattern" were associated with the risk of NAFLD compared to the lowest tertile (medium vs. lowest tertile OR= 2.37, 95%CI= 1.02-5.53; highest vs. lowest tertile OR=3.58, 95% CI= 1.48-8.68, P trend<0.001). The highest tertile of "vegetable and dairy pattern" compared to the lowest tertile was inversely associated with NAFLD risk (OR= 0.23, 95%CI= 0.09-0.58, P trend=0.02). No significant association was found between "fast food type pattern" and the risk of NAFLD.Conclusion: A significant association was observed between different dietary patterns and the risk of NAFLD. These results can potentially serve as a dietary strategy for preventing NAFLD in individuals who are at a high risk for progression of NAFLD.
