ABSTRACT

Objective To evaluate the effects of vitamin D supplementation on serum lipid profiles and neonatal prognosis in gestational diabetes mellitus(GDM)patients.Methods The electronic databases including PubMed,Web of Science,Embase,CNKI,and Wanfang Data were searched from inception to February 1,2020.All randomized controlled trials that compared vitamin D supplementation with placebo or without supplementation for GDM women were included.Paper selection,data extraction,meta-analysis and sensitivity analysis were conducted independently by two authors.Risk of bias was assessed using the Cochrane Risk of Bias Tool.The data were analyzed in RevMan 5.3 software and Stata 12.0.Results Totally 17 randomized controlled trials involving 1432 patients(704 in the intervention group and 728 in the control group)were included in the meta-analysis.The results showed that vitamin D supplementation significantly reduced serum total cholesterol [MD=-6.11,95% CI=(-7.17,-5.04)],low-density lipoprotein cholesterol [MD=-10.80,95% CI=(-14.72,-6.89)],and triglyceride [MD=-8.11,95% CI=(-10.09,-6.13)],while significantly increased serum 25-hydroxyvitamin D3 level [MD=45.45,95% CI=(41.98,48.92)] and high-density lipoprotein cholesterol [MD=2.77,95% CI=(1.59,3.96)].In addition,vitamin D supplementation significantly reduced the incidence rate of hyperbilirubinemia [RR=0.49,95% CI=(0.35,0.68)],premature birth [RR=0.44,95% CI=(0.27,0.72)],and neonatal hospitalization [RR=0.44,95% CI=(0.29,0.67)].Conclusions Vitamin D supplementation may regulate the serum lipid profiles in patients with GDM and reduce the incidence of adverse neonatal outcomes.More high-quality RCTs are needed to confirm the findings in our study.

ABSTRACT

<p><b>OBJECTIVE</b>To measure lutein, zeaxanthin and β-carotene level in foods commonly consumed in Beijing, and compare the content difference between raw and cooked food.</p><p><b>METHODS</b>Forty-six commonly consumed foods of 8 classes were collected in Haidian district of Beijing from September to October in 2009. A high performance liquid chromatography method was used to determine the content of lutein, zeaxanthin and β-carotene in both raw and cooked samples.</p><p><b>RESULTS</b>Lutein was abundant in cucurbitaceous and solanaceous, allium and nuts, especially in Chinese chive (18 226.9 µg/100 g) and pumpkin (13 265.2 µg/100 g). Major sources of zeaxanthin included round pumpkin, green garlic shoot, corn and eggs, whose level of zeaxanthin were 444.6, 283.5, 279.7, 118.6 - 377.9 µg/100 g, respectively. Zeaxanthin level of those cooked foods changed to 483.9, 239.3, 279.1, 149.5 - 594.7 µg/100 g, respectively. The zeaxanthin level of cooked Chinese chive reached 1081.2 µg/100 g, while we did not detect any zeaxanthin in raw Chinese chive. β-carotene was present in a wide variety of vegetables and fruits. Carrot (17 234.3 µg/100 g) was a good source of β-carotene, while its level in cooked carrot was 17 013.5 µg/100 g.</p><p><b>CONCLUSION</b>Consuming the proper kinds of foods and changing the method of food processing were beneficial to increase the intake of lutein, zeaxanthin and β-carotene.</p>
