1. Kimiyo Kikuchi, Takehiro Michikawa, Seiichi Morokuma, Norio Hamada, Yoshiko Suetsugu, Kazushige Nakahara, Kiyoko Kato, Masafumi Sanefuji, Eiji Shibata, Mayumi Tsuji, Masayuki Shimono, Toshihiro Kawamoto, Shouichi Ohga, Koichi Kusuhara; Japan Environment and Children’s Study Group, Association of sleep quality with temperament among one-month-old infants in The Japan Environment and Children's Study, PLos One, 10.1371/journal.pone.0274610, 17, 9, 2022.09, This study aimed to examine the association between infant sleep quality and temperament in one-month-old infants using a large cohort study data. We used data from the Japan Environment and Children's Study, a cohort study which follows around 100,000 women from pregnancy until their children's development. The mothers were asked about their infants' sleep and temperament using a structured questionnaire. Frequent crying (adjusted odds ratio [AOR]: 1.05, 95% confidence interval [CI]: 1.00-1.10) and intense crying (AOR: 1.19, 95% CI: 1.13-1.25) were positively associated with longer sleep periods during the day than at night. Female infants with longer daytime sleep periods than that at nighttime were more likely to cry frequently (AOR: 1.11, 95% CI: 1.04-1.20). Parous women with infants who had frequent night awakening believed their infants cried more intensely (AOR: 1.17, 95% CI: 1.03-1.31). The study demonstrated a specific association between sleep quality and temperament in one-month-old infants. Based on the results of this study, further sleep intervention studies are required to improve infant temperament..

Minami Noda, Yoko Sato, Yoshiko Suetsugu, Seiichi Morokuma, Interoception is associated with anxiety and depression in pregnant women: A pilot study, PLos One, 10.1038/s41598-021-03717-7, 11, 1, 2022.05, Pregnancy and postpartum are periods in which women develop psychosocially. However, becoming a mother is stressful, and mood disorders related to anxiety and depression often develop. In recent years, research on interoception-sensations related to the body's internal physiological state-has attracted attention. Interoception has multifaceted characteristics. It involves directly perceiving information in the body while also inferring and evaluating it. In this study, we examined interoception, anxiety, and depression in Japanese pregnant women. Empirical examinations and questionnaire surveys were used to measure interoception in 32 pregnant women not at high risk of pregnancy. A Japanese adaption of the Multidimensional Assessment of Interoceptive Awareness was used to measure interoceptive sensibility, and a heartbeat counting task performance was used to measure interoceptive accuracy. Anxiety and depression were measured using the Japanese versions of the State-Trait Anxiety Inventory and the Edinburgh Postnatal Depression Scale, respectively. A correlation analysis was performed between interoception, anxiety and depression and between differences between sensibility and accuracy of interoception, anxiety and depression. We revealed that interoceptive sensibility and differences between sensibility and accuracy of interoception were associated with anxiety. Based on results of this pilot study, it is necessary to investigate using longitudinal studies whether interoception might be an effective predictor tool for early detection of anxiety during pregnancy and postpartum..

Momoka Kuroda,Yoshiko Suetsugu, Sachiko Iwata, Masahiro Kinoshita, Fumie Fujita, Yoko Sato, Shinji Saitoh, Osuke Iwata, Seiichi Morokuma, Influence of mothers' nighttime responses on the sleep-wake rhythm of 1-month-old infants, Journal of Psychosomatic Research, 10.1038/s41598-021-03717-7, 11, 1, 2021.12, The purpose of this study was to analyze the influence of the mothers' nighttime responses on the sleep-wake rhythm of their 1-month-old infants. This study used an anonymous self-administered survey questionnaire with 1133 mothers of 1-month-old infants. The questionnaire investigated basic information about the parents, growth environment of infants, mothers' sleep patterns during pregnancy, and infants' sleep patterns at the age of one month. Logistic regression analysis was used to analyze the influence of nighttime responses on the risk of infants sleeping longer during the day than at night. Regarding nighttime response behavior, it was found that immediately picking up 1-month-old infants results in longer sleep during the day than at night (OR 1.616 [1.017 - 2.566], p = 0.042), compared to delaying picking up the infant. It was suggested that the stimulation due to picking up an infant may affect sleep-wake rhythm formation..
4. Yoshiko Suetsugu, Shuji Honjo, Mari Ikeda, Kiyoko Kamibeppu, The Japanese version of the Postpartum Bonding Questionnaire
Examination of the reliability, validity, and scale structure, Journal of Psychosomatic Research, 10.1016/j.jpsychores.2015.02.008, 79, 1, 55-61, 2015.07, Objective: The purpose of this study was to develop the Japanese version of the Postpartum Bonding Questionnaire (PBQ) to gather data on Japanese mothers for comparison with other cultures and to examine the scale structure of the PBQ among Japanese mothers. Methods: We administered the PBQ to a cross-section of 244 mothers 4. weeks after delivery and again 2. weeks later to 199 mothers as a retest to examine reliability. We used exploratory factor analysis to evaluate the factor structure of the PBQ. Correlations with the Mother-to-Infant Bonding Scale (MIBS), the Maternal Attachment Inventory (MAI), Edinburgh Postnatal Depression Scale (EPDS), and sociodemographic variables were calculated for validation. Results: The 14-item version of the PBQ extracted by exploratory analysis consisted of four factors: 'impaired bonding', 'rejection and anger', 'anxiety about care', and 'lack of affection'. We found significant correlations of the total scores of the PBQ and the 14-item version of the PBQ positively with the MIBS and negatively with the MAI. Moderate significant correlations with total scores were also found with the EPDS. Total scores for primiparous and depressed mothers were higher than those for multiparous mothers and mothers without depression. Conclusion: The results of this study demonstrated the reliability and validity of the PBQ and the 14-item version of the PBQ in Japanese mothers 4. weeks after delivery..
5. Yoshiko Suetsugu Megumi Haruna Kiyoko Kamibeppu, A longitudinal study of bonding failure related to aspects of posttraumatic stress symptoms after childbirth among Japanese mothers, BMC Pregnancy Childbirth, 10.1186/s12884-020-03099-0., 20, 1, 434, 2020.07, Background: Posttraumatic stress symptoms (PTSS) after childbirth may affect mother-infant bonding. This study examined the relationship between aspects of PTSS after childbirth and bonding failure for mothers at 1 month and 4 months after delivery.

Methods: This longitudinal study surveyed 130 mothers at 1 month (T1) and 4 months (T2) after delivery. We performed multiple regression analysis with the Postpartum Bonding Questionnaire (PBQ) as the dependent variable and the Impact of Event Scale-Revised (IES-R), Edinburgh Postnatal Depression Scale (EPDS), Relationship Questionnaire (RQ), Family Adaptation, Partnership, Growth, Affection, and Resolve score (F.APGAR), and demographic data as independent variables.

Results: The rate of mothers with an IES-R score of ≥ 25 was 6.2% at T1 and 3.8% at T2. The IES-R and the EPDS were relevant factors for the PBQ at T1. The IES-R was not a relevant factor, but the EPDS was a relevant factor for the PBQ at T2. The IES-R at T1 was not a predictor for the PBQ at T2. The PBQ at T1 was the largest predictor for the PBQ at T2, when compared with the EPDS, F.APGAR, and dismissive attachment pattern (RQ) at T1.

Conclusions: PTSS after childbirth had a strong influence on bonding failure at T1. However, the important factor affecting bonding failure was not PTSS after childbirth, but depression at T2. If PTSS after childbirth are accompanied by depression at T2, bonding failure may be affected. Bonding failure affected by PTSS after childbirth at T1 could affect bonding failure at T2. Health professionals should assess the degree of PTSS after childbirth and start to care for mothers at T1.
