Objectives Bonding failure is lack of parental emotional relationship between a parent and their infant. This study aims to investigate the association between father's involvements with their partner during pregnancy.Methods A total of 1,957 partners of pregnant women who had visited three maternity hospitals in Sapporo from May 2016 to December 2017 were included in the study. Self-administered questionnaires were distributed to participants at 2,435 weeks gestation and at 6-8 weeks postpartum. The fathers who responded to both the questionnaires were included in the analysis. The participants' relationship with their partners during pregnancy was rated using two questions- whether they help their partner with personal care and household chores, and whether they consult with their partner. Answers for both questions were given on a scale of 0 to 4. A total score of 6-8 points was defined as a high-score group, 3-5 points as a mid-score group, and 0-2 points as a low-score group. Bonding failure was evaluated using the Japanese version of the Mother-Infant Bonding Scale (MIBS-J). The cut-off value was the score that included the top 10% with the highest degree of bonding disorder. A logistic regression was used to analyse the association between involvement with a partner during pregnancy and bonding failure. The confounding variables were father's age, household income, father's average working hours, previous pregnancy, history of abortion/a stillbirth/the death of the child, and partner's prepartum depression during pregnancy.Results 391 fathers responded to the initial questionnaire, and 86.4% of them filled out the second questionnaire up to 2 months postpartum, 10.6% up to 3 months, 2.5% up to 4 months, and 1.0% up to 5 months. Of these, 375 were included, excluding those with missing questionnaire items. 255 fathers were in the high score group of the involvement with partner during pregnancy, 48 had bonding failure, 35 had LA, and 17 had AR. The OR based on the high score group of involvement with partner during pregnancy for bonding failure was 4.81 (1.88-12.33) for mid-score group, and 6.89 (1.40-33.93) for low-score group, and for LA, 2.21 (0.97-5.04) for mid-score group, and 6.40 (1.54-26.68) for low-score group; however, AR showed no respectively significant association (trend P 0.0005, 0.0053, 0.6859).Conclusions The results suggest that a father's unfavorable involvement with his partner affects the bonding with their infant. This suggests that involvement with a partner during pregnancy is an important factor in preventing bonding failure in fathers.
母婴情感联结失败是指父母与婴儿之间缺乏情感关系。本研究旨在调查孕期父亲与伴侣之间的互动关联。
本研究纳入了2016年5月至2017年12月期间在札幌市三家妇产医院就诊的1957名孕妇的伴侣。在妊娠24-35周及产后6-8周向参与者发放自填式问卷。对两份问卷均做出回应的父亲纳入分析。通过两个问题对参与者孕期与伴侣的关系进行评分，即是否帮助伴侣进行个人护理和家务，以及是否与伴侣商量。两个问题的答案均采用0至4分制。总分6-8分为高分组，3-5分为中分组，0-2分为低分组。采用日本版母婴情感联结量表（MIBS-J）评估母婴情感联结失败情况。临界值为情感联结障碍程度最高的前10%的得分。采用逻辑回归分析孕期与伴侣互动和母婴情感联结失败之间的关联。混杂变量包括父亲年龄、家庭收入、父亲平均工作时长、既往妊娠史、流产/死产/孩子死亡史以及伴侣孕期产前抑郁情况。
共有391名父亲对初始问卷做出回应，其中86.4%在产后2个月内填写了第二份问卷，10.6%在产后3个月内填写，2.5%在产后4个月内填写，1.0%在产后5个月内填写。其中，排除问卷项目缺失者后，375名父亲纳入分析。255名父亲在孕期与伴侣互动方面属于高分组，48名存在母婴情感联结失败，35名存在轻度情感联结失败，17名存在重度情感联结失败。基于孕期与伴侣互动高分组，母婴情感联结失败的中分组比值比为4.81（1.88-12.33），低分组为6.89（1.40-33.93）；轻度情感联结失败的中分组比值比为2.21（0.97-5.04），低分组为6.40（1.54-26.68）；然而，重度情感联结失败未显示出显著关联（趋势P值分别为0.0005、0.0053、0.6859）。
结果表明，父亲与伴侣互动不良会影响其与婴儿的情感联结。这表明孕期与伴侣互动是预防父亲母婴情感联结失败的重要因素。
