Development of Social Life Impact for Mother (SLIM) scale at first trimester to identify mothers who need social support postpartum: a hospital-based prospective study in Japan

Social life impact for mother scale at first trimester predicts postpartum suicide risk: A prospective study

OBJECTIVE

To examine whether the Social Life Impact for Mother (SLIM) scale in the first trimester predicts postpartum suicide risk.

METHODS

We used part of the hospital-based prospective study conducted in obstetric clinics and hospitals in four populous prefectures in Japan (N = 7,462). Participants completed the SLIM scale, including nine risk factors in the first trimester, and postpartum suicide risk was assessed as item-10 in the Edinburgh Postnatal Depression Scale, self-harm ideation, at one month after delivery (N = 5,697).

RESULTS

The weighted total score of the SLIM scale which was calculated using the results of odds ratio predicted postpartum suicide risk with moderate accuracy. Pregnant women with 6+ scores of the new SLIM score were 4.26 (95%CI = 3.12-5.01) times more likely to have postpartum suicide risk. The original SLIM score also predicted postpartum suicide risk. The new SLIM score showed higher accuracy than the original score.

CONCLUSION

The SLIM scale at the first trimester of prenatal checkups may be useful for obstetricians to predict postpartum suicide risk and start to provide support for the expecting mothers. Both weighted total scores could be utilized according to the purpose of implementing the SLIM scale at obstetric institutions.

Association between adverse childhood experiences and pregnancy morbidities: A nationwide online-based cross-sectional study

OBJECTIVE

To examine the association between adverse childhood experiences (ACEs) and pregnancy morbidities, including preterm birth (PTB), gestational diabetes (GDM), preeclampsia, and small-for-gestational-age (SGA) among the general population in Japan.

METHODS

The data were from the JACSIS study, an online-based nationwide survey conducted from July to August 2021 in Japan (N = 5444). ACEs included physical, sexual, and psychological abuse, neglect, childhood poverty, bully victimization, domestic violence, parental death, and parental divorce. Pregnancy morbidities, including PTB, GDM, preeclampsia, and SGA were identified through questionnaires. A multivariable logistic regression model was applied.

RESULTS

Of 5444 women, 2778 (51.0%) had no ACEs, and 374 (6.9%) had four or more ACEs. A dose-response association was found between total ACE score and PTB and preeclampsia (p-value: 0.016 and 0.001). Women with four or more ACE scores showed higher risks of preeclampsia (adjusted odds ratio [aOR] [95% confidence interval, CI]: 3.06 [1.57-5.94], p-value: 0.001). Besides, those with two or three ACEs had higher risks of PTB (aOR [95%CI]: 1.42 [1.01-2.02], p-value: 0.046, and aOR [95%CI]: 1.61 [1.04-2.50], p-value: 0.041), and women with one ACE showed a higher risk of GDM (aOR [95%CI]: 1.34 [1.02-1.77], p-value: 0.035). SGA was not associated with ACEs.

CONCLUSION

ACEs were associated with an increased risk of PTB, preeclampsia, and GDM, but not SGA among the general population in Japan.

Years of education mediate the association between adverse childhood experiences and unintended pregnancy: A population-based study in Japan

BACKGROUND

Adverse childhood experiences (ACEs) have been associated with unintended pregnancies, including mistimed pregnancies (MP) and unwanted pregnancies (UWP). However, it remains unknown which cluster of ACEs (i.e., child maltreatment/household dysfunction and deprivation/threat) are associated with MP/UWP and whether years of education mediate these associations.

OBJECTIVE

To investigate the association of the clusters of ACEs with MP and UWP, while also examining the mediating effect of education years.

PARTICIPANTS AND SETTING

A retrospective cohort study among 7652 postpartum women in Chiba, Japan.

METHODS

MP/UWP was defined by emotional responses to confirming pregnancy. Multinomial logistic regression analyses with multiple imputed datasets estimated the relative risk ratio (RRR) of MP/UWP by cumulative scores and each cluster of ACEs. Causal mediation analysis assessed the indirect effects of years of education.

RESULTS

Women with 4 or more ACEs were at a 2.4 times higher risk of MP (95 % confidence interval (CI): 1.6-3.8) and a 5.0 times higher risk of UWP (95 % CI: 3.1-8.2). Among ACE clusters, having 3 or more household dysfunction showed the strongest association with MP (RRR: 1.91, 95 % CI: 1.23-2.95), and having 3 or more deprivation showed the strongest association with UWP (RRR: 3.69, 95 % CI: 2.00-6.83). Education years mediated 16 % and 11 % of the association between total ACEs and MP/UWP, respectively, with a similar trend observed in each cluster.

CONCLUSIONS

Not only ACEs score but also each cluster of ACEs was associated with MP and UWP. The mediating effects of years of education were modest.

Association between poor parent-daughter relationships and the risk of hyperglycemia in pregnancy: a hospital-based prospective cohort study in Japan

BACKGROUND

Adverse child experiences (ACEs), childhood maltreatment and household dysfunction, are risk factors of hyperglycemia in pregnancy (HIP), including diabetes before pregnancy, gestational diabetes (GDM), and overt diabetes in pregnancy, through increased risk of unhealthy behaviors, obesity, and stress response system dysfunction. While ACEs are often difficult to be assessed in hospital settings, parent-daughter relationship, that is, pregnant women's relationship with their parents can be considered as a measurable maker for ACEs that may be associated with HIP. The purpose of this study is to examine the association between poor parent-daughter relationship and HIP.

METHODS

Hospital-based prospective cohort study was conducted in Japan (N = 6,264). Women visiting participating 58 facilities for delivery between April 2019 and March 2020 were included. Parent-daughter relationship was assessed by a questionnaire asking whether participants were satisfied with their relationship with their parents. HIP was diagnosed based on the criteria used in Japan. A multiple logistic regression model was applied to adjust for covariates.

RESULTS

Pregnant women who were not very satisfied and not satisfied at all with the relationship with their parents, and HIP were 343 (5.5%), 74 (1.2%), and 274 (4.4%), respectively. Pregnant women who were not very satisfied with their parent-daughter relationship showed a significant positive association with HIP in the crude model (odds ratio (OR): 1.71, 95% confidence interval (CI): 1.11-2.63). When stratified by psychiatric disease history, we found a significant positive association among those without psychiatric disease history (OR: 1.77, 95% CI: 1.11-2.84), but not among those with psychiatric disease history (OR: 0.61, 95% CI: 0.16-2.28).

CONCLUSIONS

Poor parent-daughter relationship was associated with the risk of HIP among pregnant women without psychiatric disease history, suggesting that this simple question could be used to estimate the risk of HIP when it was challenging to inquire directly about ACEs. Further research is needed to elucidate the mechanism of the association.

Impact of adverse childhood experience on physical and mental health: A life-course epidemiology perspective

Adverse childhood experiences (ACEs) have been shown to have long-term effects on physical and mental health, not only in the US, but also other countries, including Japan. In this paper, measurement of assessment of ACEs has been discussed, that is, concept (what is ACEs), inquiry (how to ask about ACEs), scoring (how to count the number of ACEs), and prevalence (how many ACEs do we have). In addition, a possible mechanism on how ACEs affect health was summarized from a life-course perspective, using the critical/sensitive period model, pathway model, and cumulative model with recent evidence on neurological findings. Intergenerational transmission, that is, maternal ACEs affecting the health of the offspring was also reviewed. Finally, future directions on how to prevent and remedy the impact of ACEs on health was discussed.
