Bonding is crucial to perinatal mental health. Despite an extensive body of literature on maternal bonding, few studies have focused on paternal bonding. This scoping review aimed to clarify the current state of the concept of paternal–infant/fetus bonding. The eligibility criteria were drawn from the population concept and context elements to answer the following questions: “what is paternal bonding?” and “what are the constructs of the concept of paternal bonding?” The review comprised 39 studies. Paternal bonding was associated with both positive and negative paternal behavior and thought and may be determined based on fathers’ beliefs and rearing history. Most studies showed that father–child interaction is one of the factors promoting paternal bonding. However, fathers generally felt more distant from their babies post-delivery than mothers. Only a few studies originally defined paternal bonding; most relied on the definitions of maternal bonding. We found different descriptions lacking consensus. Few studies examined the differences between paternal and maternal bonding. No consensus exists on the concept, constructs, and assessment of paternal bonding. The causal relationship between paternal bonding and other variables is unexplored. Future studies should explore fathers’ perspectives and experiences, focusing on the unknown aspects of paternal bonding identified in this review.

Gestational anemia (GA) is a global health concern with a remarkably high prevalence in Japan, which is associated with various maternal and neonatal outcomes. This study aimed to explore whether GA and non-anemic iron deficiency (NAID) during the third trimester is associated with maternal characteristics, nutrient intake, low birth weight (LBW), and preterm birth. Participants were categorized into GA, NAID, and normal groups, based on serum ferritin and hemoglobin levels. Nutrient intake was assessed using the Brief Diet History Questionnaire. Data from 317 pregnant women were analyzed, including 110 (34.7%), 151 (47.6%), and 56 (17.6%) women in the GA, NAID, and normal groups, respectively. Factors associated with GA included being multipara (p < 0.001) and not taking any type of iron supplements in the third trimester (p = 0.043). The normal group had a significantly higher proportion of preterm birth and LBW than the GA and NAID groups. The GA group had a significantly higher energy intake than the normal group (p = 0.044). Overall, energy and micronutrient intake were significantly below the estimated average requirement in the dietary reference intakes for Japanese. Health care professionals need to consider nutritional advice that can prevent GA by focusing on overall micronutrients, not just energy intake.

Intense fear of childbirth by expectant women is called tokophobia. Because there are no qualitative studies targeting women with an intense fear of childbirth in Japan, it is unknown whether there is any link between the type of fear of objects/situations among tokophobic women and their psychological/demographic background. Furthermore, there is no available summary of the lived experience of Japanese women with tokophobia. This study aims to identify the intensity patterns of various types of fear among the participants and summarize the lived experience of having intense fear of childbirth. A qualitative descriptive study was conducted using a semi-structured interview. Pregnant women with an intense fear of childbirth participated in individual interviews facilitated by a psychiatrist and a midwife. Audio recordings of the interviews were transcribed and analyzed using a content analysis approach. The number of participants was ten. The types of feared objects varied individually and these were categorized as being related to either prospective or retrospective fear. The participants’ experiences were grouped into three categories: difficulty in daily life, preoccupied negative expectation towards childbirth, and psychological adaptation to the upcoming childbirth. The results imply that women with tokophobia continuously suffer from fear in their daily life; hence, a special approach is needed to detect and reduce their fear.

Tokophobia is regarded as the intensive fear of childbirth that some pregnant women have. However, little is known about the psychopathological details of tokophobia (fear of childbirth). Between 2020 and 2021, a total of 10 pregnant women (nine nulliparae and one multipara) with a strong fear of childbirth were referred by obstetricians. Semi-structured psychopathological interviews were conducted, and two cases were judged to have obsession, three an overvalued idea, and one secondary delusion. Three were characterised by both obsession and overvalued idea and one by both obsession and secondary delusion. In total, six cases had features of an overvalued idea. All of the participants except one had a lifetime history of a specific phobia. In addition, their history included social phobia in two cases, panic disorder in one case, obsessive–compulsive disorder (other than tokophobia) in two cases, depressive disorder in two cases, bipolar disorder in two cases, and PTSD in six cases. To conclude, this study showed that tokophobia was not a phobic disorder but a kind of overvalued idea that requires specific assessment and treatment.

Aim: To describe national standard care for newborn bathing and its influential factors.Methods: A global survey was conducted using a web‐based questionnaire. The targeted countries were 166 member countries of either the International Confederation of Midwives (ICM) or the International Council of Nurses (ICN). An eligible person included someone well informed of midwifery education/training or neonatal care, including newborn bathing, in their country. To examine the factors associated with the standard care for newborn bathing, information on mean annual temperature, precipitation, gross domestic product per capita, and basic water coverage was collected as external factors. Student's t tests and Chi‐square tests were used for analysis.Results: Care standards were identified in 46 countries: seven from Africa, eight from the Americas, 15 from Asia, 14 from Europe, and two from Oceania. In most countries, newborns were bathed with warm water in a tub within 10 min. Bathing frequency, moisturization, and use of soap or cleanser varied by country. There were significant associations between bathing frequency and temperature and between moisturization and precipitation.Conclusion: The national standard care for newborn bathing in each country was unique. Standard bathing care was associated with the climate. More consideration should be given to the differences in standard care for newborn bathing between countries when interpreting existing studies and conducting future studies on neonatal skin care.
