To determine coital incidence at term and to estimate its effect on labor onset and mode of delivery.
Healthy women with uncomplicated pregnancies and established gestational age were recruited to keep a diary of coital activity from 36 weeks of gestation until birth and to answer a short questionnaire. Two hundred women with complete coital diaries were available for analysis. Outcome measures include coitus, postdate pregnancy (defined as pregnancy beyond the estimated date of confinement), gestational length of at least 41 weeks, labor induction at 41 weeks of gestation, and mode of delivery
Reported sexual intercourse at term was influenced by a woman's perception of coital safety, her ethnicity, and her partner's age. After multivariable logistic regression analysis controlling for the women's ethnicity, education, occupation, perception of coital safety, and partner's age, coitus at term remained independently associated with reductions in postdate pregnancy (adjusted odds ratio [AOR] 0.28, 95% confidence interval [CI] 0.13-0.58, P = .001), gestational length of at least 41 weeks (AOR 0.10, 95% CI 0.04-0.28, P < .001), and requirement for labor induction at 41 weeks of gestation (AOR 0.08, 95% CI 0.03-0.26, P < .001). At 39 weeks of gestation, 5 (95% CI 3.3-10.3) couples needed to have intercourse to avoid one woman having to undergo labor induction at 41 weeks of gestation. Coitus at term had no significant effect on operative delivery (adjusted P = .15).
Reported sexual intercourse at term was associated with earlier onset of labor and reduced requirement for labor induction at 41 weeks.

- "As most activities are transient in nature, the timing of these activities may be important as a possible acute trigger of pregnancy complications such as preterm birth, placental abruption, premature spontaneous rupture of membranes and preeclampsia. Pregnant women have been asked to report the frequency of performing every-day activities during specific trimesters[4,9,11-13] or any time during pregnancy[3,14-16]; however, to investigate these activities as acute triggers it is important to know their prevalence in a smaller window of time. The aim of this study is to ascertain the prevalence of selected activities in any seven day period during pregnancy. "

ABSTRACT: Research into the effects of common activities during pregnancy is sparse and often contradictory. To examine whether common activities are an acute trigger of pregnancy complications the prevalence of these activities are necessary to determine sample size estimates. The aim of this study is to ascertain the prevalence of selected activities in any seven day period during pregnancy.
The study was conducted in the antenatal clinic of a teaching hospital with tertiary obstetric and neonatal care in Sydney, Australia between August 2008 and April 2009. Women who were at least 20 weeks pregnant and able to read English completed a questionnaire to assess whether they had performed a list of activities in the seven days prior to survey completion. Results were analysed using frequency tabulations, contingency table analyses and chi square tests.
A total of 766 surveys were completed, 29 surveys were excluded as the women completing them were less than 20 weeks pregnant, while 161 women completed the survey more than once. Ninety seven per cent of women completed the survey when approached for the first time, while 87% completed the survey when approached a subsequent time. In the week prior to completing the survey 82.6% of women had consumed a caffeinated beverage, 42.1% had had sexual intercourse, 32.7% had lifted something over 12 kilograms, 21.4% had consumed alcohol and 6.4% had performed vigorous exercise. The weekly prevalence of heavy lifting was higher for multiparous women compared to nulliparous women.
The results of this study can be used to inform future research into activities as acute triggers of pregnancy complications.

ABSTRACT: The aim of this study is to assess the opinions and the practice of pregnant women on sexuality during pregnancy in an african setting. It is a voluntary and anonymous cross sectional survey conducted in September 2004 in an antenatal clinic in Bobo Dioulasso, Burkina Faso. Data collected are analyzed using EPI INFO 2000. A total of 95 pregnant women were interviewed. The profile of the woman who participated in the study is as followed: a mean age of 25 years, having no formal literacy, mainly housewife and Muslim, engaged in a monogamous marriage in 50% of the cases and bearing a pregnancy of 5 months of gestational age. The women's opinions on sexuality during pregnancy are stated as followed: for 92.6% sexual intercourse is possible during pregnancy and that is not related to their instruction level (χ2=4.4 and p=0.81). In 85% of the cases, the women say that they have sexual intercourse during the time of the survey and that is related to the fact that they thought that sexual intercourse is possible during pregnancy (χ2=14.47 and p=0.005) but not related to the gestational age (χ2=13.2 and p=0.67). The majority of the women (60%) say that sexual intercourse has no harmful effect on the baby to be born. The two main reasons given by the women for sexual activity during pregnancy are the pleasure of the couple follow az ed by the pleasure of their partner.
