ABSTRACT
Seasons and Vitamin D are factors that are directly and indirectly related to ultraviolet (UV) radiations and can affect pregnancy. Therefore, the present study aims at investigating the effects of being exposed to direct UV radiation during pregnancy period and its effects on fetal growth, premature birth, and high blood pressure. This study was conducted by searching different websites such as Medline, Embase, ProQuest, Global Health, Google Scholar, and Scopus. Of the 430 papers found, between 1985 and 2017, seventeen related articles were used. The results showed that being exposed to UV radiation during the first 3 months of pregnancy is associated with improved fetal growth and causes high blood pressure during pregnancy. The literature shows that being women exposure to UV radiation had beneficial effects on fetal growth and blood pressure during pregnancy period. However, since this issue has not been extensively studied in the past, the results from previous studies should be generalized with extreme care and caution. Therefore, it is suggested that further studies be carried out in this area.
ABSTRACT
BACKGROUND: Self-medication is a serious health problem that leads to an increased per capita consumption of medications, drug resistance, lack of optimal treatment, drug poisoning, and other unwanted complications. This study was conducted to compare self-medication in pregnant and nonpregnant women presenting to Shahid Akbar Abadi Teaching Hospital in Tehran, Iran. MATERIALS AND METHODS: To conduct this cross-sectional study, 210 pregnant women and 210 nonpregnant women aged 15-45 years presenting to Shahid Akbar Abadi Teaching Hospital, Tehran, Iran, were selected through random sampling. Data were collected through interviews using a semi-structured questionnaire. The Chi-square test, t-test, and logistic regression model were used to analyze the data. RESULTS: The prevalence of self-medication was 34.8% in the pregnant and 77.1% in the nonpregnant women. The age group in which the most frequent instances of self-medication were observed (53.4%) was the 21-30 age group in the pregnant women and the 31-40 age group (44.4%) in the nonpregnant women, suggesting a statistically significant intergroup difference in terms of age (P = 0.0001). Medicinal plants were the most common medications used by the pregnant women (19.6%) and synthetic medications were the most common used by the nonpregnant women (38.1%). The reasons for using medications without a prescription included believing in the illness being mild (22.8%), not having health insurance (9%), easy access in the pregnant women, a previous history of the illness, and easy access in the nonpregnant women. CONCLUSIONS: As medicinal plants are the most common medications used by pregnant women and since assessing the risk of herbal substances is difficult, pregnant women should be advised against the arbitrary use of these substances.
ABSTRACT
INTRODUCTION AND OBJECTIVE: The majority of formerly conducted studies have focused on the prevalence of posttraumatic stress disorder merely during pregnancy period; however, pregnancy period is by itself accompanied with the stress of getting pregnant again; therefore, the present study was conducted to evaluate the prevalence of posttraumatic stress disorder (PTSD) during pregnancy and postpartum period. METHODS: A total of 3475 articles were found by searching keywords of PTSD, pregnancy, stress, and birth, through various research databases, including PubMed, Google Scholar, and Science Direct; 37 papers turned out to be completely relevant, 18 of which had provided through examination of the prevalence of intended disorder. RESULTS: The prevalence rate varied from 0% to 21% in community-related samples; this rate varied from 0% to 43% in high-risk samples. CONCLUSION: PTSD is a common phenomenon during pregnancy and postpartum period, and it might get worse and worse unless it is diagnosed and treated after delivery. Thus, it is recommended to assess pregnancy and postpartum services.
