    BACKGROUND: The COVID-19 pandemic has affected every aspect of our lives, including the decision to become pregnant. Existing literature suggests that infertility and the decision to delay childbearing at a younger age are associated with a lower level of well-being and regrets when women start to desire a baby. Thus, the decision to delay childbearing due to the pandemic could negatively affect the well-being of women. This study focuses on how pregnancy decisions affect the well-being of women during the COVID-19 pandemic. METHODS: From the Japan COVID-19 and Society Internet Survey, a nationally representative web-based survey, 768 observations of married women aged 18 to 50 years who had the intention of getting pregnant during the pre-pandemic period (conducted in 2020 and 2021) were used. Loneliness, severe psychological distress, and suicidal ideation were used as well-being indicators. For pooled data, a generalised estimated equation (GEE) model was used to estimate how pregnancy decision related to well-being indicators. For a sub-analysis, the sample was divided by the survey year and a Poisson regression model was used. RESULTS: The GEE analysis showed an association between delaying childbearing and severe psychological distress, with the prevalence ratio (PR) being 2.06 [95% CI (1.40-3.03)]. Furthermore, loneliness and suicidal ideation that occurred after the beginning of the pandemic were significantly related to the decision to delay childbearing-1.55 [95% CI (1.03,2.34)] and 2.55 [95% CI (1.45-4.51)], respectively. Moreover, these PRs were larger for 2021 compared to 2020. CONCLUSION: During the COVID-19 pandemic, approximately one-fifth of married women who had childbearing intentions before the pandemic decided to postpone pregnancy. They exhibited a deteriorated mental health state. Furthermore, the negative associations were larger in 2021 compared to 2020. Loneliness has negative consequences for both mental and physical health, as well as elevated severe psychological distress and suicidal ideation among those who decided to postpone pregnancy. Therefore, the current results should not be overlooked by society.

    <jats:title>Abstract</jats:title><jats:sec>
    <jats:title>Background</jats:title>
    <jats:p>Although many conventional healthcare services to prevent postpartum depression are provided face-to-face, physical and psychosocial barriers remain. These barriers may be overcome by using mobile health services (mHealth). To examine the effectiveness of mHealth professional consultation services in preventing postpartum depressive symptoms in real-world settings, we conducted this randomized controlled trial in Japan, where universal free face-to-face perinatal care is available.</jats:p>
    </jats:sec><jats:sec>
    <jats:title>Methods</jats:title>
    <jats:p>This study included 734 pregnant women living in Yokohama city who could communicate in Japanese, recruited at public offices and childcare support facilities. The participants were randomized to the mHealth group (intervention, <jats:italic>n</jats:italic> = 365), where they could use a free app-based mHealth consultation service with gynecologists/obstetricians, pediatricians, and midwives whenever and as many times as they wanted between 6 p.m. and 10 p.m. on weekdays throughout their pregnancy and postpartum periods (funded by the City of Yokohama government) or the usual care group (control, <jats:italic>n</jats:italic> = 369). The primary outcome was the risk of elevated postpartum depressive symptoms, defined as Edinburgh Postnatal Depression Scale score ≥ 9. Secondary outcomes were self-efficacy, loneliness, perceived barriers to healthcare access, number of clinic visits, and ambulance usage. All outcomes were collected three months post-delivery. We also conducted subgroup analyses assessing the differences in the treatment effect by sociodemographic status.</jats:p>
    </jats:sec><jats:sec>
    <jats:title>Results</jats:title>
    <jats:p>Most women completed all questionnaires (<jats:italic>n</jats:italic> = 639 of 734, response rate: 87%). The mean baseline age was 32.9 ± 4.2 years, and 62% were primipara. Three months post-delivery, women in the mHealth group had a lower risk of elevated postpartum depressive symptoms (47/310 [15.2%]) compared to the usual care group (75/329 [22.8%], risk ratio: 0.67 [95% confidence interval: 0.48–0.93]). Compared with the usual care group, women in the mHealth group had higher self-efficacy, less loneliness, and fewer perceived barriers to healthcare access. No differences were observed in the frequency of clinic visits or ambulance usage. Furthermore, in the subgroup analyses, we did not find differences in the treatment effect by sociodemographic status.</jats:p>
    </jats:sec><jats:sec>
    <jats:title>Conclusions</jats:title>
    <jats:p>Local government-funded mHealth consultation services have a preventive effect on postpartum depressive symptoms, removing physical and psychological barriers to healthcare access in real-world settings.</jats:p>

    Japan has faced a decline in fertility since the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to investigate the rate of pregnancy postponement and its contributing factors, with a particular focus on economic- and COVID-19 infection-related indicators. This study used data from 768 observations of married women aged 18 to 50 years with pregnancy intentions. The data were obtained from two rounds of a large web-based survey conducted by the Japan COVID-19 and Society Internet Survey (JACSIS) in 2020 and 2021. A generalised estimating equation (GEE) model was employed, as well as Poisson regression models for sub-sample analysis divided by year to estimate the year differential magnitude of the contributing factors' impacts. Approximately 20% of married women with childbearing intentions postponed their childbearing. The analyses revealed that declining income and anxiety about future household finances were significantly related to delayed childbearing, while fear of COVID-19 and infection rate were not. Additionally, the adverse effects of unfavourable economic conditions were stronger in 2021. Notably, age did not influence the decision of pregnancy postponement. Older women postponed pregnancy just as much as younger women. In conclusion, this study confirmed that the COVID-19 pandemic, particularly its related adverse economic conditions, contributed to Japan's current baby bust. Considering that advanced maternal age is already common in Japan, this decreased fertility may result in the long-term negative consequence of further population decline.

    <jats:p>We investigated the effects of enabling Osekkai, the traditional Japanese behavior of creating a helping culture, on social participation among rural people in rebuilding social connections that can be vital during the coronavirus diseases 2019 (COVID-19) pandemic. The subjects of this cross-sectional study were people interested in the Osekkai conference (control group) and those actively involved in Osekkai activities (exposure group). The primary outcome of social participation was measured as the frequency of meeting and the number of friends or acquaintances. The demographic data of the participants and process outcomes were measured using a questionnaire provided to all 287 registered participants. The effective response rate was 64.5% (185 responses). The involvement in Osekkai conferences was statistically associated with a high frequency and number of meetings with friends or acquaintances (p &lt; 0.001 and 0.048, respectively). A health check was significantly associated with the number of friends or acquaintances met in the previous month, while high social support was significantly associated with loneliness. Thus, we confirm that Osekkai contributes to high social participation, although we see no relationship with loneliness. Future studies should investigate this cause-and-effect relationship and promote culturally sensitive activities to improve social and health outcomes in rural Japan.</jats:p>
