“…12 Self-referral during pregnancy, which was considered a disaster-related factor, did not affect the duration of gestation in the 2011 data. 14 Further analysis comparing outcomes between pregnancies conceived before and after the disaster is currently ongoing. 15 The incidence of small-for-gestational age infants was affected by neither area in Fukushima nor trimester of pregnancy at the time of the disaster.…”

The Pregnancy and Birth Survey was started by Fukushima Medical University as part of the Fukushima Health Management Survey in 2011 in order to assess the physical and mental health of mothers and provide parenting support (telephone counseling) for those in need. The present study reviewed the major findings from 4 annual surveys conducted from 2011 to 2014. Overall proportions of preterm deliveries, low birth weight infants, and congenital anomalies in the first year were almost the same as those in national surveillance data. The prevalence of depressive symptoms among the mothers held steady at about 25% over the 4 years. Regarding the content of parenting counseling, the proportion of mothers who voiced concerns about radiation decreased each year. This survey should be continued to provide support to mothers in Fukushima.

“…We noticed an overall decrease in the absolute number of patients admitted in the Obstetrics ward and for reasons related to ‘Pregnancy, childbirth and the puerperium’, of which 94% consists of deliveries, after Haiyan compared to baseline (Tables 1 and 2 ). The evidence about the effects of disasters on pregnancy is mixed: one study suggests that disasters do not influence the gestational period [ 19 ], while another suggests that they can cause preterm labour [ 20 ]. Therefore, we expected the number of deliveries to either remain stable over time or increase within the study period.…”

The impact of Typhoon Haiyan on admissions in two hospitals in Eastern Visayas, Philippines

ObjectivesWe investigated the short-term impact of Typhoon Haiyan, one of the strongest typhoons ever to make landfall, on the pattern of admissions in two hospitals in Eastern Visayas, the Philippines.MethodsThis study took place at Eastern Visayas Regional Medical Center (EVRMC) in Tacloban, and Ormoc District Hospital (ODH) in Ormoc. We determined whether there were differences in the pattern of admissions between the week before and the three weeks after Haiyan by using information on sex, age, diagnosis, ward and outcome at discharge from patient records.ResultsThere was a drop in admissions in both hospitals after Haiyan as compared to before. Admissions climbed back to the baseline after ten days in EVRMC and after two weeks in ODH. When comparing the period after Haiyan to the period before, there was a relative increase in male versus female admissions in ODH (OR 2.8, 95%CI 1.7–4.3), but not in EVRMC. Patients aged ≥50 years and 0–14 years had the highest relative increase in admissions. There was a relative decrease in admissions for the ICD10 group ‘Pregnancy, childbirth and the puerperium’ (OR 0.4, 95%CI 0.3–0.6), and an increase in ‘Certain infectious and parasitic diseases’ (OR 2.1, 95%CI 1.2–3.5), mainly gastroenteritis, and ‘Diseases of the respiratory system’ (OR 1.8, 95%CI 1.0–3.0), mainly pneumonia, compared to all other diagnosis groups in ODH. Out of all reasons for admission within the study period, 66% belong to these three ICD-10 groups. Data on reasons for admission were not available for EVRMC.ConclusionsThe observed reduction in patients after the Typhoon calls for ensuring that hospital accessibility should be protected and reinforced, especially for pregnant women, by trying to remove debris in the direct hospital vicinity. Hospitals in areas prone to tropical cyclones should be prepared to treat large numbers of patients with gastroenteritis and pneumonia, as part of their disaster plans.

“…They experienced the earthquake between the fourth and 37th weeks of their gestational period. 11 The results showed that pregnant women who changed perinatal checkup institutions due to medical indications had a significantly shorter gestation duration and more preterm births than those who visited only one institution. However, self-referral, which could indicate post-disaster relocation, was not significantly associated with shorter gestation and preterm birth, 11 suggesting that the GEJE and the subsequent accident at the Fukushima Daiichi Nuclear Power Plant did not have a direct impact on gestational duration.…”

There are limited studies on the long-term effects of natural/environmental disasters, especially nuclear disasters, on obstetric outcomes. This study aimed to review the results of perinatal outcomes immediately after the Great East Japan Earthquake (GEJE) and the Fukushima Daiichi Nuclear Power Plant accident, as well as their long-term trends over 8 years, in the Fukushima Health Management Survey. The annual population-based Pregnancy and Birth Survey is conducted as part of the Fukushima Health Management Survey. The Fukushima Prefecture government launched it to assess the health conditions of pregnant women and their neonates after the GEJE. The self-reported questionnaire was sent to 115,976 pregnant women by mail from January 2012, with 58,344 women responding to the questionnaire (50.3% response rate). Pregnancy complications, such as gestational hypertension, respiratory diseases, and mental disorders, increased in some women who were pregnant at the time of the earthquake and immediately after the earthquake. However, the direct effects on newborns, such as preterm birth, low birth weight, and congenital anomalies, were not immediately clear after the earthquake. Although there were significant differences in the occurrence of preterm birth and low birth weight among the districts, there was no change in the occurrences of preterm birth, low birth weight, or anomalies in newborns in Fukushima Prefecture from the fiscal year 2011 to the fiscal year 2018. Therefore, the long-term effects of the post-disaster radiation accident on perinatal outcomes are considered to be very small.
