- چکیده انگلیسی: Background
The aim of this study was to determine the relationship between maternal anemia during pregnancy and pregnancy outcomes.
Materials and Methods
This systematic review was conducted in domestic (Sid, Iran.doc, Iran medex and Magiran) and international (PubMed, Science Direct, Cochrane, Medline, Web of Science, Scopus, Springer, Embase, Google scholar) databases from January 1, 1990 to April 10, 2016 with using standard key words "Pregnancy", "Pregnant women", "Hemoglobin/ haemoglobin", "Anemia/ anaemia", and "Pregnancy outcome". Relative risks (RR) and confidence intervals were extracted from each study.
Results
Overall 30 studies with a total sample size of 1,194,746 were entered into the final meta-analysis. Maternal anemia in the first trimester showed a significant relationship with low birth weight (RR: 1.28, 95% CI, 1.10 - 1.50, P<0.01), pre-term birth (RR: 1.26, 95% CI, 1.11- 1.44, P<0.01) and small for gestational age (RR: 1.12, 95% CI, 1.05 - 1.19, P<0.01`), that means maternal anemia in the first trimester raises the risk of these outcomes.
Even though, maternal anemia in the second trimester has no significant relationship with low birth weight (RR, 1.19, 95% CI, 0.65- 2.17, P>0.05) and pre-term birth (RR: 1.35, 95% CI, 0.54 - 3.24, P>0.05). Similarly, maternal anemia in the third trimester has also, no significant relationship with low birth weight (RR: 1.23, 95% CI, 0.97 - 1.55, P>0.05) and pre-term birth (RR: 1.55, 95% CI, 0.83 - 2.88, P>0.05).
Conclusion
Maternal anemia during pregnancy in the first trimester in particular can be considered as a risk factor for pregnancy outcomes and must be treated as an advance.- انتشار مقاله: 13-04-1395

- چکیده:
- چکیده انگلیسی: Background: Controversial results have been reported concerning the influence of calcium intake on prostate cancer
risk. The aim of this study was to determine any association between total calcium (in the diet and in supplements) intake
and prostate cancer. Materials and Methods: The present systematic review and meta-analysis study was carried out
following a PRISMA guidelines. Two reviewers independently using MeSH keywords searched international databases
including PubMed, Science Direct, Cochrane, EMBASE, Web of Science, CINAHL, EBSCO and search engines such
as Google Scholar. The searches were performed without any time limit until May 2016. The results were pooled
using a random effects model and homogeneity was confirmed using the Q test and I2 index. Subgroup analyses was
performed according to continents and study designs. The data were analyzed using STATA software version 3.2, with
pfinal meta-analysis. The main age range of the participants was 50 to 70 years. The relative risks (RR) for total calcium
with total prostate cancer, localized prostate cancer, and advance prostate cancer were estimated to be 1.15 (95% CI:
1.04-3.46), 1.05 (95% CI: 0.96-1.14), and 1.15 (95% CI: 0.89-1.50), respectively. Only the relationship between total
calcium and total prostate cancer was significant (P<0.05). Conclusions: High calcium intake can be considered as a
risk factor for total prostate cancer. Therefore, calcium intake might be a target for prevention.- انتشار مقاله: 04-07-1396
