The General Practice Research Database was used to examine prescribing of the combined oral contraceptive pill for females aged under 16 in England and Wales in 1997. From these data, calculations were made to estimate prevalence for these countries; family planning clinic return data were combined with the general practice estimates to give an overall figure of 4.2 per 100. This extent of use ...

We previously described how data from family planning research can be presented and summarised.1 In this paper we will describe how to use data obtained from a sample to answer questions about the population. For example, we might use data from a survey to estimate how many women purchase hormonal emergency contraception over-thecounter from pharmacies. Or we might seek to answer the question, ...

To study the problem of nausea and vomiting in early pregnancy an epidemiological survey was undertaken, obtaining information from 500 consecutive antenatal patients. Seventy-six percent of women complained of symptoms during the first trimester, and in only 27% had the symptoms resolved by the twelfth week. Job efficiency was markedly impaired. Women who suffered nausea premenstrually, or on ...

Title: Adherence to the oral contraceptive pill: a cross-sectional survey of modifiable behavioural determinants Author's response to reviews: I was advised to resubmit this paper by the BMC Family Practice editorial team, as BMC Public Health seems like a more appropriate venue. We have made minor changes to make the manuscript more appropriate to a Public Health audience. The manuscript was n...

INTRODUCTION By the age of 35 years, most women would have completed their families and contraception then becomes an important consideration. In the next one or two decades, other health concerns such as osteoporosis, dysfunctional uterine bleeding, ovarian, endometrial, colorectal and breast cancers and cardiovascular diseases will assume prominence in the lives of women. We review the role o...

BACKGROUND Over 100 million women worldwide are using oral contraceptives pills (OCP) and mood changes were being as the primary reason for OCP discontinuation. The purpose of this study was to determine the prevalence and predicting factors of mood changes in oral contraceptive pills users. METHODS This was a cross-sectional study of 500 women aged 15-49 years old using low dose (LD) pills a...

BACKGROUND Extended use of the combined oral contraceptive pill (COC), defined as taking active pills for at least 28 days, has been used in order to avoid bleeding at important times and to treat gynaecological conditions such as endometriosis. We examined the main issues involved in extended use of the COC and how it has evolved from being one of medicine's best-kept secrets to becomin...

In the past few years the more liberal attitude to therapeutic abortion and the widespread use of the oral contraceptive pill have led to a decrease in the number of babies available for adoption. Donor artificial insemination (AID) has been practised in Britain for some years, mainly in the private sector. Owing to a change in the influence of legal, ethical, and theological considerations it ...

based on epidemiologic data, women who take oral contraceptives seem to have an increased risk of developing thromboembollic disease. the thrombotic effects of oral contraceptive (oc) are probably mediated, at least partly through their effects on the coagulation system. plasma levels of several clotting factors have been shown to be elevated in oc users, and this increase is graduated accordin...

E1278 CMAJ, December 13, 2011, 183(18) © 2011 Canadian Medical Association or its licensors The lifetime incidence of venous thromboembolism for both men and women is estimated at 1 per 1000. Increasing our understanding of the precipitating risk factors, as well as optimizing the prevention of this condition in high-risk populations, could help to reduce the burden of venous thromboembolism.
