ABSTRACT
Background: The multiple pregnancy incidence is increasing worldwide. This increased incidence is concerning to the health care system. This study aims to determine the frequency of multiple pregnancy and identify factors that affect this frequency in Tehran, Iran
Materials and Methods: This cross-sectional study included 5170 mothers in labor between July 6-21, 2015 from 103 hospitals with Obstetrics and Gynecology Wards. The questionnaire used in this study consisted of five parts: demographic characteristics; information related to pregnancy; information related to the infant; information regarding the multiple pregnancy; and information associated with infertility. We recruited 103 trained midwives to collect data related to the questionnaire from eligible participants through an interview and medical records review. Frequencies and odds ratios [OR] for the association between multiple pregnancy and the selected characteristics [maternal age, economic status, history of multiple pregnancy in first-degree relatives, and repro-ductive history] were computed by multiple logistic regression. Stata software, version 13 [Stata Corp, College Station, TX, USA] was used for all statistical analyses
Results: Multiple pregnancy had a prevalence of 1.48% [95% confidence interval [CI]: 1.19-1.85]. After controlling for confounding variables, we observed a significant association between frequency of multiple pregnancy and mother's age [OR=1.04, 95% CI: 1.001-1.09, P=0.044], assisted reproductive technique [ART, OR=6.11, 95% CI: 1.7-21.97, P=0.006], and history of multiple pregnancy in the mother's family [OR=5.49, 95% CI: 3.55-9.93, P=0.001]
Conclusion: The frequency of multiple pregnancy approximated results reported in previous studies in Iran. Based on the results, we observed significantly greater frequency of multiple pregnancy in older women, those with a history of ART, and a history of multiple pregnancy in the mother's family compared to the other variables
ABSTRACT
Background: Few studies have been conducted on the infertility problems in Iran. This study aimed to investigate the prevalence of infertility problems and related factors in Iranian infertile patients
Materials and Methods: In this cross sectional study, 405 infertile patients referred to Royan Institute, Tehran, Iran, between 2014 and 2015, were selected by simple random sampling. Participants completed the Fertility Problem Inventory [FPI] including 46 questions in five domains [social concern, sexual concern, relationship concern, rejection of parenthood, and need for parenthood]. Mean difference between male and female was verified using independent-samples Student's t test. A generalized linear model [GLM] was also used for testing the effect of variables on the fertility problems. Data was analyzed using Stata software version 13
Results: The mean age [SD] of participants was 31.28 [5.42]. Our results showed that 160 infertile men [95.23%] were classified as very high prevalence of infertility problems. Among infertile women, 83 patients [35.02%] were as very high prevalence of infertility problems, and 154 patients [64.98%] were as high prevalence. Age [P<0.001], sex [P<0.001], a history of abortion [P=0.009], failure of previous treatment [P<0.001], and education [P=0.014] had a significant relationship with FPI scores
Conclusion: Bases on the results of current study, an younger male with lower education level, history of abortion and history of previous treatments failure experienced more infertility problems
