What are the characteristics and circumstances of pregnancies men report as unintended in France?
Pregnancies reported as unintended were most prevalent among young men with insecure financial situations, less stable relationships and inconsistent use of contraception or false assumptions about their partner's use of contraception.
Efforts to involve men in family planning have increased over the last decade; however, little is known about factors associated with men's pregnancy intentions and associated contraceptive behaviours.
STUDY DESIGN, SIZE, DURATION: The data presented in this study were drawn from the nationally representative FECOND study, a population-based survey conducted in France in 2010. The sample comprised 8675 individuals (3373 men), aged 15-49 years, who responded to a telephone interview about socio-demographics and topics related to sexual and reproductive health. The total refusal rate was 20%.
PARTICIPANTS/MATERIALS, SETTING, METHODS: This study included 2997 men, of whom 664 reported 893 recent pregnancies (in the 5 years preceding the survey). Multivariate Poisson's regression with population-averaged marginal effects was applied to assess the individual and contextual factors associated with men's intentions for recent pregnancies. The contraceptive circumstances leading to the unintended pregnancies were also assessed.
Of all heterosexually active men, 5% reported they had experienced an unintended pregnancy with a partner in the last 5 years. A total of 20% of recent pregnancies reported by men were qualified to be unintended, of which 45% ended in induced abortion. Of pregnancies following a previous unintended pregnancy, 68% were themselves unintended. Among all heterosexually active men, recent experience of an unintended pregnancy was related to age, mother's education, age at first sex, parity, contraceptive method history, lifetime number of female partners and the relationship situation at the time of survey. Recent unintended pregnancies were also related to pregnancy order and to the financial and professional situation at the time of conception. The majority of unintended pregnancies occurred when men or their partners were using contraceptives; 58% of contraceptive users considered that the pregnancy was due to inconsistent use and 39% considered that it resulted from method failure. Half of the non-users who reported an unintended pregnancy thought that their partner was using a contraceptive method. The relative risk of non-use of a contraceptive method during the month of conception of a recent unintended pregnancy was higher among those without a high school degree (IRR = 2.9, CI 1.6, 5.2) and higher among men for whom the pregnancy interfered with education (IRR = 1.8, CI 1.0, 3.1) or work (IRR = 1.9, CI 1.1, 3.6).
LIMITATIONS, REASONS FOR CAUTION: From the perspective of men, the unintended pregnancy rates may be underestimated due to a combination of underreporting of abortion and post-rationalization of birth intentions. Our use of a dichotomous measure of unintended pregnancy is unlikely to fully capture the multidimensional construct of pregnancy intentions.
These results call for gender-inclusive family planning programmes, which fully engage men as active participants in their own rights.
STUDY FUNDING/COMPETING INTERESTS: The FECOND study was supported by a grant from the French Ministry of Health, a grant from the French National Agency of Research (#ANR-08-BLAN-0286-01; PIs N.B., C.M.), and funding from National Institute of Health and Medical Research (INSERM) and the National Institute for Demographic Research (INED).

在法国,男性报告的意外怀孕有哪些特征和情况?
报告为意外的怀孕在经济状况不稳定、关系较不稳定、避孕措施使用不一致或对伴侣避孕情况存在错误认知的年轻男性中最为普遍。
在过去十年中,让男性参与计划生育的努力有所增加;然而,对于与男性怀孕意愿及相关避孕行为有关的因素知之甚少。
研究设计、规模、持续时间:本研究中的数据来自具有全国代表性的FECOND研究,这是2010年在法国进行的一项基于人群的调查。样本包括8675人(3373名男性),年龄在15至49岁之间,他们通过电话访谈回答了有关社会人口统计学以及性与生殖健康相关主题的问题。总拒绝率为20%。
参与者/材料、背景、方法:本研究纳入了2997名男性,其中664人报告了893次近期怀孕(在调查前的5年中)。应用具有总体平均边际效应的多变量泊松回归来评估与男性近期怀孕意愿相关的个体和背景因素。还评估了导致意外怀孕的避孕情况。
在所有有异性性行为的男性中,5%报告称在过去5年中与伴侣经历过意外怀孕。男性报告的近期怀孕中,共有20%被认定为意外怀孕,其中45%以人工流产告终。在之前意外怀孕后的怀孕中,则有68%本身也是意外怀孕。在所有有异性性行为的男性中,近期意外怀孕的经历与年龄、母亲的教育程度、初次性行为的年龄、生育状况、避孕方法使用史、女性伴侣的终身数量以及调查时的恋爱状况有关。近期意外怀孕还与怀孕顺序以及受孕时的经济和职业状况有关。大多数意外怀孕发生在男性或其伴侣正在使用避孕措施时;58%的避孕使用者认为怀孕是由于使用不一致,39%认为是方法失败导致。报告意外怀孕的非避孕使用者中有一半认为其伴侣正在使用避孕方法。在近期意外怀孕受孕当月未使用避孕方法的相对风险,在没有高中学历的人群中更高(发病率比值比=2.9,置信区间1.6,5.2);在怀孕影响到教育(发病率比值比=1.8,置信区间1.,0,3.1)或工作(发病率比值比=1.9,置信区间1.1,3.6)的男性中也更高。
局限性、谨慎理由:从男性的角度来看,由于人工流产报告不足和生育意愿事后合理化的综合影响,意外怀孕率可能被低估。我们对意外怀孕采用的二分法测量不太可能完全涵盖怀孕意愿的多维度结构。
这些结果呼吁实施性别包容的计划生育项目,让男性作为自身权利的积极参与者充分参与其中。
