To study the relationship of soy foods and nuts consumption during early pregnancy with the risk of gestational diabetes mellitus (GDM).This was a prospective observational study conducted in Southwest China. Dietary information was assessed through 3-day 24-h dietary recalls at 6-14 gestational weeks. For soy foods and nuts, non-consumers were used as the reference category and the consumers were categorized into tertiles. GDM was assessed with the 75-g, 2-h oral glucose tolerance test at 24-28 gestational weeks. Log-binomial models were used to assess the effects of soy foods and nuts on GDM.Of the 1495 pregnant women, 529 were diagnosed with GDM. Median (IQRs) intakes of soy foods and nuts were 2.9 (0.0, 10.3) and 5.0 (0.0, 15.0) g/d, respectively. Our study found that, compared with the non-consumers, the highest tertile of soy foods intake was associated with a decrease in risk of GDM (RR = 0.73, 95%CI: 0.54-0.99,Consumption of soy foods and nuts are independently inversely associated with the risk of GDM during early pregnancy.

To examine the association between fruit intake and blood glucose metabolism.Healthy singleton pregnant women with 6-14 weeks of gestation were selected in a maternal-and-child health care institution in Chengdu from February to July 2017. Dietary information was obtained by 3-day 24-hour dietary recall during each trimester, and the average daily total fruit intake per person were calculated. According to the Dietary guidelines for Chinese pregnant women(2016), insufficient rates of fruits were calculated, and the participants were divided into insufficient intake group, suitable intake group and higher intake group. Multiple linear regression was used to analyze the association between fruit intake during pregnancy and fasting blood glucose, 1-h plasma glucose and 2-h plasma glucose. Log-binomial regression model was used to analyze the association between fruit intake during pregnancy and the risk of gestational diabetes mellitus(GDM).Valid samples of 1453 cases in early pregnancy, 1049 cases in middle pregnancy were included, the age was(28.5±4.0)years old. The average fruit intake during the early and middle pregnancy(M(P25, P75)) were 279.7(180.8, 415.2) g/d and 232.0(100.0, 390.0) g/d, respectively. The insufficient rates were 18.8% and 43.2%, respectively. After adjusting for age, pre-pregnancy BMI, education level, family income, family history of diabetes, parity, physical activity, energy, vegetables, grains, red meat, and beverages, multiple linear regression result showed that compared with the insufficient fruit intake group, in the suitable fruit intake group, the fasting blood glucose level was decreased(β=-0.071, 95%CI-0.111--0.003). Results of log binomial regression analysis showed that when compared with the fruit suitable intake group during the second trimester, the insufficient intake group may increase the risk of GDM(RR=1.13, 95% CI 1.11-1.58); no association between fruit intake during the early pregnancy and blood glucose metabolism was observed.Fruit intake during pregnancy is associated with blood glucose metabolism. The appropriate amount of fruit intake may improve fasting blood glucose and insufficient intake of fruits during the second trimester may increase the risk of GDM.

Background: More than one-fifth of the world’s population consumes Chinese cuisines regularly, but no evidence-based healthy diets fitting the Chinese food culture are available for implementation. Methods: A multicenter, patient- and outcome assessor–blind, randomized feeding trial was conducted among 265 participants with 130 to 159 mm Hg baseline systolic blood pressure (SBP) for 4 major Chinese cuisines (Shangdong, Huaiyang, Cantonese, Szechuan). After a 7-day run-in period on a control diet matching the usual local diets, participants were randomized to continue with the control diet or the cuisine-based Chinese heart-healthy diet for another 28 days. The primary outcome was SBP, and secondary outcomes included diastolic blood pressure and food preference score. Linear regression models were used to estimate the intervention effects and adjustments for the center. The incremental cost per 1 mm Hg reduction in SBP was also calculated. Results: A total of 265 participants were randomized (135 on the Chinese heart-healthy diet and 130 on the control diet), with 52% women, mean age of 56.5±9.8 years, and mean SBP and diastolic blood pressure of 139.4±8.3 and 88.1±8.0 mm Hg, respectively, at baseline. The change in SBP and diastolic blood pressure from baseline to the end of the study in the control group was –5.0 (95% CI, –6.5 to –3.5) mm Hg and –2.8 (95% CI, –3.7 to –1.9) mm Hg, respectively. The net difference of change between the 2 groups in SBP and diastolic blood pressure were –10.0 (95% CI, –12.1 to –7.9) mm Hg and –3.8 (95% CI, –5.0 to –2.5) mm Hg, respectively. The effect size did not differ among cuisines ( P for interaction=0.173). The mean food preference score was 9.5 (with 10 the best preferred) at baseline, and the net change during intervention was 0.1 (95% CI, –0.1 to 0.2; P =0.558). The incremental cost-effectiveness ratio per 1 mm Hg SBP reduction was CNY 0.4 (USD 0.06) per day. No difference in the number of adverse events was found between the 2 groups ( P =0.259), and none of the adverse events was associated with the intervention. Conclusions: The Chinese heart-healthy diet is effective, palatable, and cost-effective in reducing blood pressure in Chinese adults with high blood pressure, with a clinically significant effect applicable across major Chinese cuisine cultures.

The purpose of this study was to evaluate the association between starchy vegetable consumption and subgroup consumption in the first trimester and the risk of gestational diabetes mellitus (GDM).A prospective study (Among the 1444 participants in our study, 520 were diagnosed with GDM. The adjusted RRs (95% CIs) for GDM from the lowest to the highest quartiles of total starchy vegetable consumption were 1.00 (reference), 1.29 (1.06, 1.57), 1.13 (0.93, 1.40), and 1.26 (1.02, 1.56), respectively;A higher consumption of total starchy vegetables and potatoes in the first trimester is associated with a greater risk of GDM.

Objectives:Fruit intake may influence gestational diabetes mellitus (GDM) risk. However, prospective evidence remains controversial and limited. The current study aimed to investigate whether total fruit and specific fruit intake influence GDM risk.Design:A prospective cohort study was conducted. Dietary information was collected by a 3-d 24-h dietary recall. All participants underwent a standard 75-g oral glucose tolerance test at 24–28 gestational weeks. Log-binomial models were used to estimate the association between fruit intake and GDM risk, and the results are presented as relative risks (RR) and 95 % CI.Setting:Southwest China.Participants:Totally, 1453 healthy pregnant women in 2017.Results:Total fruit intake was not associated with lower GDM risk (RR of 1·03 (95 % CI 0·83, 1·27) (Ptrend = 0·789)). The RR of GDM risk was 0·73 for the highest anthocyanin-rich fruit intake quartile compared with the lowest quartile (95 % CI 0·56, 0·93; Ptrend = 0·015). A higher grape intake had a linear inverse association with GDM risk (Q4 v. Q1: RR = 0·65; 95 % CI 0·43, 0·98; Ptrend = 0·044), and after further adjustment for anthocyanin intake, the inverse association tended to be non-linear (Q4 v. Q1: RR = 0·65; 95 % CI 0·44, 0·98; Ptrend = 0·079). However, we did not find an association between glycaemic index-grouped fruit, glycaemic load-grouped fruit or other fruit subtype intake and GDM risk.Conclusions:In conclusion, specific fruit intake (particularly anthocyanin-rich fruit and grapes) but not total fruit intake was inversely associated with GDM risk.

We aimed to examine the association between low-carbohydrate diet (LCD) scores during the first trimester and gestational diabetes mellitus (GDM) risk in a Chinese population. A total of 1455 women were included in 2017. Dietary information during the first trimester was collected by 24-h dietary recalls for 3 d. The overall, animal and plant LCD scores, which indicated adherence to different low-carbohydrate dietary patterns, were calculated. GDM was diagnosed based on the results of a 75-g, 2-h oral glucose tolerance test at 24–28 weeks gestation. Log-binomial models were used to estimate relative risks (RR) and 95 % CI. The results showed that the multivariable-adjusted RR of GDM from the lowest to the highest quartiles of the overall LCD score were 1·00 (reference), 1·15 (95 % CI 0·92, 1·42), 1·30 (95 % CI 1·06, 1·60) and 1·24 (95 % CI 1·01, 1·52) (P = 0·026 for trend). Multivariable-adjusted RR (95 % CI) of GDM from the lowest to the highest quartiles of the animal LCD score were 1·00 (reference), 1·20 (95 % CI 0·96, 1·50), 1·41 (95 % CI 1·14, 1·73) and 1·29 (95 % CI 1·04, 1·59) (P = 0·002 for trend). After additional adjustment for gestational weight gain before GDM diagnosis, the association of the overall LCD score with GDM risk was non-significant, while the association of animal LCD score with GDM risk remained significant. In conclusion, a low-carbohydrate dietary pattern characterised by high animal fat and protein during the first trimester is associated with an increased risk of GDM in Chinese women.

To investigate the folate intake level of early pregnant women and its influencing factors in Chengdu.The healthy singleton pregnant women with 8-14 weeks of pregnancy in an obstetrical clinic of maternal-and-child health care institution in Chengdu in 2017 were selected as the object of the study. The basic information of pregnant women was collected by questionnaire survey, and the dietary intake of all kinds of food in early pregnancy was collected by 3-day 24-hour dietary recall method, and the average daily intake of folate was calculated according to China Food Composition(2018). A self-designed questionnaire was used to collect the use of folic acid supplements in pregnant women in the past one month, and the average daily intake of folic acid supplements was calculated. According to the Chinese Dietary Reference Intakes(2013), the folate intakelt;600 μg DFE/d was defined as insufficient, and folic acid supplements intake ≥1000 μg/d was defined as excessive. The influencing factors of folate intake were analyzed by binary Logistic regression model.A total of 1579 valid samples were included. The average folate intake of early pregnant women in Chengdu was 865.8(778.6, 1461.0) μg DFE/d, the average dietary folate intake was 145.4(101.9, 200.7) μg/d, and the average folic acid supplements intake was 400.0(400.0, 800.0) μg/d. The rate of insufficient intake of folate in early pregnancy was 12.1%, and the rate of excessive intake of folic acid supplements was 13.0%. Compared with the primiparous group, the risk of insufficient folate intake was higher in the multiparous group(OR=1.708, 95%CI 1.175-2.482). Compared with the low income group, risk of insufficient folate intake in the medium and high income group was lower(OR=0.660, 95%CI 0.477-0.913); taking folic acid supplements before pregnancy has a lower risk of overdose of folic acid than the non-taking group(OR=0.594, 95%CI 0.423-0.835).The phenomenon of insufficient intake of total folate and excessive intake of folic acid supplements coexists among women in early pregnancy in Chengdu, and the rational use of folic acid supplements is worthy of attention.

To evaluate the red meat intake of pregnant women in Chengdu area and explore the effect of red meat intake in the first and second trimesters on gestational diabetes mellitus(GDM).From February to July 2017, a prospective study was conducted among healthy singleton pregnant women within 8-14 weeks of gestation in a prenatal clinic of maternal-and-child medical institution in Chengdu City through purposive sampling. Data on maternal demographic characteristics was collected through questionnaire in early pregnancy. 3-day 24 hour dietary recall was used to collect dietary intake information in the first and second trimesters. The 75 g oral glucose tolerance test(OGTT)was conducted at 24 to 28 weeks of gestation, and GDM was diagnosed according to the Guidelines for the Diagnosis and Treatment of Pregnancy Diabetes in China(2014). Multivariate unconditional Logistic regression model was used to explore the association between tertiles of red meat intake and the risk of GDM in the first and second trimesters.A total of 985 valid samples were followed up. The mean intake of total meat and red meat in middle pregnancy(102. 9 g/d and 74. 6 g/d) was higher than that in early pregnancy(70. 7 g/d and 52. 0 g/d). The difference was statistically significant(Plt;0. 05). Red meat accounted for 73. 6% and 72. 5% of total meat intake in early and middle pregnancy, respectively. After adjusting the confounding factors, multivariate unconditional Logistic regression analysis showed the risk of GDM was 1. 499 times(95%CI 1. 028-2. 185) in the highest red meat intake(gt;86 g/d)women compared with the lowest red meat intake(lt;44 g/d) women in the second trimester. No association was found between red meat intake in the first trimester and the occurrence of GDM(OR=1. 029, 95%CI 0. 716-1. 481).Pregnant women in Chengdu area have excessive intake of red meat in the second trimester. Higher intake of red meat in the second trimester(gt;86 g/d) may increase the risk of gestational diabetes.

To investigate the effects of anxiety and depression on gestational diabetes mellitus(GDM) in early pregnancy.A prospective study was conducted in 2017 to select 1426 single-child healthy pregnant women of 8-14 weeks from the Sichuan Provincial Hospital for Women and Children through a deliberate sampling method. The age was(28. 6±4. 0) years old. Basic information such as age, pre-pregnancy weight, parity, and gravidity of pregnant women was collected through questionnaire survey. The anxiety self-rating scale(SAS) and depression self-rating scale(SDS) were used to collect information of anxiety and depression in pregnant women, and their anxiety and depressive symptoms were evaluated according to the result of Chinese norm. At 24 to 28 weeks of gestation, the oral glucose tolerance test(OGTT) was conducted. GDM was diagnosed according to the Guidelines for the Diagnosis and Treatment of Pregnancy Diabetes in China(2014). Multivariate unconditional Logistic regression was adopted to analyze the effects of anxiety and depression on GDM in pregnant women.The incidence of GDM in early pregnancy anxiety group and depression group was 41. 8% and 33. 6%, respectively. The incidence of anxiety, depression, and anxiety combined with depression were 7. 7%, 10. 5% and 4. 8%, respectively. The incidence of anxiety and depression in the group of pregnant women younger than 30 years old(9. 0% and 11. 7%) was higher than that in the group of pregnant women older than 30 years old(5. 3% and 8. 1%). The prevalence of anxiety and depression in the group of nulliparous women(8. 8% and 11. 9%) was higher than that in the group of multiparous women(5. 4% and 6. 4%). The difference was statistically significant(Plt;0. 05). After adjusting the confounding factors such as age, pre-pregnancy body mass index, family history of diabetes, gravidity, parity, energy intake, conception, education, occupation, smoking and drinking, the result showed that the risk of GDM in anxious pregnant women was increased, compared with that in non-anxious pregnant women in early pregnancy(OR=1. 556, 95% CI 1. 014-2. 387). However, the association between early pregnancy depression and the occurrence of GDM was not found(Pgt;0. 05). Compared with the non-anxiety group in the early pregnancy, the risk of GDM in the anxiety group was increased both in pregnant women under 30 years old(OR=1. 654, 95% CI 1. 004-2. 726) and nulliparous women(OR=1. 633, 95% CI 1. 013-2. 634). No correlation between anxiety and risk of GDM was observed in pregnant women over 30 years old and multiparous women(Pgt;0. 05).Anxiety in early pregnancy increases the risk of GDM. Pregnant women under 30 years old and and nulliparous women are at high risk of anxiety.

Objective To investigate whether plasma lipid profiles are independently associated with pregnancy complications including gestational diabetes mellitus (GDM), hypertensive disorder complicating pregnancy (HDCP), and intrahepatic cholestasis of pregnancy (ICP). Study Design A prospective study was conducted among 1,704 pregnant women at three medical institutions in Chengdu, China. The concentrations of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were measured at gestational weeks 12 ± 1, 24 ± 1, and 34 ± 1. Logistic regression models were used to estimate the association between lipid profiles and pregnancy complications. Receiver operating characteristic analysis was performed to determine the value of lipid profiles to predict GDM and HDCP. Results After adjusting for potential confounders, TG, TC, and LDL-C in the first trimester were independently associated with GDM (TG: odds ratio [OR] =2.00, 95% confidence interval [CI]: 1.57–2.56; TC: OR = 1.38, 95% CI: 1.16–1.64; LDL-C: OR = 1.43, 95% CI: 1.14–1.79) and HDCP (TG: OR = 2.42, 95% CI: 1.56–3.78, TC: OR = 1.64, 95% CI: 1.04–2.57; LDL-C: OR = 1.87, 95% CI: 1.07–3.25). The TC concentration during the whole pregnancy (first trimester: OR = 1.53, 95% CI: 1.13–2.08; second trimester: OR = 1.31, 95% CI: 1.06–1.61; third trimester: OR = 1.39, 95% CI: 1.17–2.04) and LDL-C in the last two trimesters (second trimester: OR = 1.62, 95% CI: 1.30–2.04; third trimester: OR = 1.56, 95% CI: 1.29–1.88) were positively associated with ICP. HDL-C in the third trimester was negatively associated with the risk of ICP (OR = 0.46, 95% CI: 0.22–0.98). Combining lipid profiles in the first trimester with the other common predictors to predict GDM or HDCP owned stronger predictive power with the largest area under the curve (GDM: 0.643 [95% CI: 0.613–0.673], HDCP: 0.707 [95% CI: 0.610–0.804]) than either indicator alone. Conclusion Maternal lipid profiles during the whole pregnancy are significantly associated with GDM, HDCP, and ICP. Combining lipid profiles in the first trimester with the other common predictors could effectively improve the power of predicting GDM and HDCP.

Nicotinamide phosphoribosyltransferase (Nampt) is a key enzyme in the nicotinamide adenine dinucleotide (NAD+) biosynthetic pathway. Exogenous extra cellular Nampt has been reported to increase the synthesis of pro-fibrotic molecules in various types of renal cells. However, the role of endogenous Namptenzymatic activity in diabetic renal cells, particularly those associated with inflammation and fibrosis through the nuclear factor (NF)-κB p65 and sirtuin 1 (Sirt1) pathway is still unknown. In the present study, a possible mechanism by which endogenous Nampt upregulation affects the expression of pro-inflammatory and pro-fibrotic cytokines in vivo and in vitro, is reported. The present results demonstrate that the expression of vimentin and fibronectin was directly implicated in endogenous Nampt upregulation. The expression levels of Poly(ADP-ribose) polymerase-1, NF-κB p65, forkhead box protein O1 and B-cell lymphoma 2-like protein 4 were also significantly increased at 96 h compared with control group (P
