Recent media attention has been given to an apparent shift away from hormonal methods of contraception. While an increase in fertility awareness-based or 'natural' family planning methods is reported in the grey literature, there are no robust data to determine any such trend in the UK.
We compared self-reported contraceptive use at conception among patients presenting for abortion at British Pregnancy Advisory Service from January to June 2018 (N=33 495) and January to June 2023 (N=55 055) using chi-square (χ) tests of association.
Reported use of fertility awareness-based methods of contraception around the time of conception increased from 0.4% in 2018 to 2.5% in 2023 (p<0.001). In contrast, use of hormonal methods of contraception decreased from 18.8% in 2018 to 11.3% in 2023 (p<0.001) and use of long-acting reversible contraception fell from 3% to 0.6% (p<0.001). Those reporting using no contraception at the time of conception significantly increased by 14% (p<0.001) when comparing data from 2018 (55.8%) with data from 2023 (69.6%).
Significantly fewer abortion patients report using effective methods of contraception around conception while also reporting an increased use of fertility awareness-based methods. Further research is needed to understand the reasons for this change.
近期，媒体关注的焦点明显转向了非激素避孕方法。虽然灰色文献报道了基于生育意识或“自然”计划生育方法的使用有所增加，但在英国，尚无有力数据来确定是否存在这样的趋势。
我们使用卡方（χ）关联检验，比较了2018年1月至6月（N = 33495）和2023年1月至6月（N = 55055）在英国怀孕咨询服务中心寻求堕胎的患者在受孕时自我报告的避孕方法使用情况。
据报告，受孕前后使用基于生育意识的避孕方法的比例从2018年的0.4%增至2023年的2.5%（p<0.001）。相比之下，激素避孕方法的使用从2018年的18.8%降至2023年的11.3%（p<0.001），长效可逆避孕方法的使用从3%降至0.6%（p<0.001）。将2018年（55.8%）和2023年（69.6%）的数据进行比较时，报告在受孕时未采取任何避孕措施的人数显著增加了14%（p<0.001）。
明显更少的堕胎患者报告在受孕前后使用有效避孕方法，同时报告基于生育意识的方法使用有所增加。需要进一步研究以了解这一变化的原因。
