Nausea and vomiting of pregnancy (NVP) is a common problem for pregnant women. Researchers have recently paid special attention to complementary medicine methods for the treatment of NVP. Regarding the high prevalence of NVP as well as maternal and fetal adverse effects of chemical drugs, the present study, focusing on clinical trials carried out in Iran, was conducted to assess safety and efficacy of different nonpharmacological methods in relieving NVP. This systematic review focused on randomized controlled trials (RCTs) and assessed complementary medicine on NVP for which databases including MedLib, Magiran, Iran Medex, SID, PubMed, Scopus, and Google Scholar search engines from 2000 to 2015 were searched. Those articles that gained score 3 or higher, according to Jadad criteria, were recruited for the study. In this study, 31 clinical trials assessing NVP were conducted on Iranian pregnant women. After removing ten articles, 21 articles with scores 3 and higher, according to Jedad criteria, were assessed. Out of 21 papers, 10 papers were about ginger, one was about cardamom, one was about lemon, two were about peppermint aromatherapy, six were about pericardium 6 (P6) acupressure, and one article about KID21 acupressure. Most studies have demonstrated a positive effect on reducing NVP; however, no adverse effect was reported. According to the results of this review, the majority of methods employed were effective in reducing the incidence of NVP, among which ginger and P6 acupressure can be recommended with more reliability.

The relationship between households' socioeconomic situation (SES) and children dental caries has been assessed in many Iranian studies to evaluate the effect of public dental care programs supporting the poor. Hence, this study through systematic review and meta-analysis has presented a conclusion in this regard. Domestic and foreign databases were searched using keywords designed by concept map. Time limit to search the databases included articles published from 1994 to 2017. Twenty-five articles were entered to the final step of the study, in which 49 relationships between SES and dental caries were assessed. Heterogeneity between studies was assessed using I2. Publication bias has been assessed using funnel plot and Egger's test. The data were assessed by STATA 13.1. Odds ratio and mean difference of children dental caries in high SES households in comparison with low SES households were 0.41 (confidence interval [CI]: 0.30, 0.52) and −0.49 (CI: −0.85, −0.13), respectively. The CI in both cases did not include “null or no effect line,” so there was a significant inverse relation between SES and dental caries. Despite the emphasis on upstream documents on equity in access to dental health services, there was high difference between SES groups in this regard. It is necessary to revise dental health programs at the country level to decrease these differences.
