This study aimed to determine the completion rate of the London Measure of Unplanned Pregnancy (LMUP) and identify socio-demographic characteristics associated with unplanned pregnancy. The results showed that 70.6% of women who completed the LMUP had planned pregnancies, but fewer than half had undertaken health-related actions prior to conceiving.
ObjectiveTo determine the completion rate for the London Measure of Unplanned Pregnancy (LMUP), a psychometrically validated measure of a woman's intention with regard to a current or recent pregnancy, during booking visits at two metropolitan antenatal care clinics; to identify socio-demographic characteristics associated with unplanned pregnancy.Design, setting, participantsRetrospective cohort study; analysis of LMUP data for women attending antenatal care booking consultations as public patients in the Sydney Local Health District, 31 December 2019 - 30 November 2020.Main outcome measuresProportions of women with LMUP scores indicating unplanned (0-9) or planned pregnancies (10-12); associations between planned pregnancy and socio-demographic characteristics, crude and adjusted for age, parity, and socio-economic status (Index of Relative Socioeconomic Disadvantage).ResultsOf 4993 women with antenatal care bookings, the LMUP was completed by 2385 (47.8%; 1142 of 3564 women at the tertiary referral hospital [32.0%], 1118 of 1160 at the secondary hospital [96.3%]). Planned pregnancies were indicated by the total LMUP scores of 1684 women (70.6%); 1290 women (59.1%) reported no health actions in preparation for pregnancy. In multivariable analyses, planned pregnancies were more likely in all age groups than for women aged 24 years or younger (30-34 years: adjusted odds ratio [aOR], 2.54; 95% confidence interval [CI], 1.76-3.66; 35-39 years: aOR, 2.91; 95% CI, 1.95-4.33). The likelihood of planned pregnancy declined with increasing parity (v no previous births: three previous births: aOR, 0.25; 95% CI, 0.16-0.40; four or more previous births: aOR, 0.10; 95% CI, 0.05-0.19).ConclusionSeven in ten women who completed the LMUP had planned their pregnancies, but fewer than half had undertaken health-related actions prior to conceiving. Higher parity was associated with unplanned pregnancy, indicating the importance of postpartum contraception advice. Overcoming barriers to implementing the LMUP more widely would enhance preconception health monitoring.
