Consultation patterns and provision of contraception in general practice before teenage pregnancy: case-control study

Abstract

Objectives: To determine patterns of consultation in general practice and provision of contraception before teenage pregnancy.

Design: Case-control study, with retrospective analysis of case notes.

Setting: 14 general practices in Trent region.

Subjects: 240 registered patients (cases) with a recorded conception before the age of 20. Three controls per case were matched by age and practice.

Main outcome measures: Consultations in general practice and provision of contraception in the 12 months before conception and recorded provision of contraception at any time before conception.

Results: Overall, 223 cases (93%) had consulted a health professional at least once in the year before conception, 171 (71%) had discussed contraception in this time, and 121 (50%) had been prescribed oral contraception. Cases were more likely to have consulted in the year before conception than controls (odds ratio 2. 70, 95% confidence interval 1.56 to 4.66). Most of the difference was owing to consultation for contraception. Overall, 53 cases (22%) resulted in a termination of pregnancy. Cases whose pregnancy ended in a termination were more likely to have received emergency contraception than either their controls (3.21, 1.32 to 7.79) or cases resulting in other outcomes (3.01, 1.06 to 8.51).

Conclusions: Most teenagers who became pregnant attended general practice in the year before pregnancy, and many had sought contraceptive advice. The reluctance of teenagers to attend general practice for contraception may be less than previously supposed. The association between provision of emergency contraception and pregnancy ending in termination emphasises the need for continuing follow up of teenagers consulting for this form of contraception.

PIP: In western Europe, UK has the highest teenage pregnancy rate among 15-19 year olds. Although general practice is one source of provision of contraception, it has been suggested that teenagers are reluctant to seek advice because of difficulty in gaining access and fears about confidentiality. This case-control study determined patterns of consultation in general practice and provision of contraception before teenage pregnancy. A total of 240 cases with a recorded conception before age 20 and 719 matched controls were identified. Overall, results show that most teenagers who became pregnant attended a general practice in the year before pregnancy, and many had sought contraceptive advice. Cases were more likely to have consulted a doctor in the year before conception than controls (odds ratio, 2.70; 95% confidence interval, 1.56-4.66). An association between provision of emergency contraception and pregnancy ending in termination was found. This finding emphasizes the need for continuing follow-up of teenagers consulting for this form of contraception.
