In a large-scale disaster, medical professionals need to access medication records and provide medicines to people who cannot return home to take their daily medicines. We investigated the proportion of carrying the paper notebook or availability of the smartphone application of the medication record among people who are assumed to have difficulty in taking their medicines during large-scale disasters.

In Japan, a web-based survey was conducted in 2018 by randomly selecting adults ≥ 20 years of age.

There were 2286 medication record owners in 3082 participants. Of the medication record owners, 784 (34.3%) took medicines that could not be missed for even a day. Among them, 724 used paper notebooks alone, 26 used smartphone applications alone, and 34 used both. Among the 724, 208 (28.8%) always carried a paper notebook. Among the 26, 16 (61.5%) could use their applications anytime. Therefore, among the 784, at least 560 (71.4%) could not always access their medication information.

An awareness campaign to carry paper notebooks and install applications for medication records should be held, since only a limited number of people carry their medication records and always have access to their medication information.

The association between high sugar-sweetened beverages (SSB) intake during pregnancy and offspring overweight/obesity has been reported only from Western countries. The objective of this study was to examine the association between SSB intake before and during pregnancy and offspring overweight/obesity among Japanese women.

Japanese prospective birth cohort study.

We analysed mother–offspring pairs who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study from 2013 to 2017. SSB intake during pregnancy was evaluated using the FFQ and classified into three groups: none (0 g/d), medium (<195 g/d) and high (>195 g/d). Overweight or obesity at 1 year of age in offspring was defined as having a BMI Z-score greater than 2 sd, calculated based on the BMI reference data for Japanese children. Multiple logistic regression analyses were performed to examine the associations between SSB intake before and during pregnancy and offspring overweight/obesity, after adjusting for covariates.

Japanese mother–offspring pairs (n 7114).

The overweight/obesity rate of the offspring was 8·8 %. Pregnant women with a high intake of SSB in early to mid-pregnancy had a higher risk of overweight/obesity in their offspring compared with those who did not; the OR was 1·52 (95 % CI (1·09, 2·12)).

High SSB intake in early to mid-pregnancy was associated with an increased risk of offspring overweight/obesity at 1 year of age.

We aimed to investigate the association between types of housing and allergic symptoms at 3–4 years following the Great East Japan Earthquake.

Our study was based on the ToMMo Child Health Study conducted in 2014 and 2015, a cross-sectional survey of public school children in Miyagi Prefecture, Japan. Of the 46 648 invited schoolchildren in the 2nd to 8th grades, 9884 were included. Presence of eczema, wheezing, and mental health symptoms was defined with questionnaires. To calculate odds ratios (ORs) and 95% CIs for the associations between types of housing and eczema or respiratory symptoms, we fitted generalized linear mixed models, included a random effect for municipality of residence, and adjusted for sex, school grade, survey year, and mental health symptoms.

Prefabricated temporary housing was significantly associated with eczema symptoms (OR, 1.46; 95% CI, 1.06–2.02). Even after adjusting for the presence of mental health symptoms, our analysis produced similar results (OR, 1.42; 95% CI, 1.03–1.96). Conversely, it was not significantly associated with respiratory symptoms (OR, 0.97; 95% CI, 0.61–1.54).

Children living in prefabricated temporary housing had a higher prevalence of eczema symptoms; however, prevalence of respiratory symptoms was not significantly higher.

We aimed to clarify the correlation between the 2011 Great East Japan Earthquake and pregnant women’s awareness of social capital 3 to 9 months after the tsunami disaster.

We analyzed data on responses to a questionnaire by 7451 pregnant women in their second to third trimesters. The proportions of social capital–related items were calculated in the north and south coastal areas of Miyagi Prefecture and were compared with national samples. The factors associated with social capital were estimated by use of multivariate logistic regression analyses.

The proportion of women feeling that they had helpful neighbors was higher (69.0% vs 56.7%, P=0.0005), the proportion of women regarding their communities as safe and secure was lower (51.7% vs 62.4%, P=0.002), and the proportion of women feeling that most people were trustworthy was lower (23.7% vs 32.9%, P=0.006) in the north coastal area than nationwide. Such differences were not observed in the less severely affected south coastal area. Age of 35 years or older, extended family, college or university graduation, and being multiparous were associated with the feeling of having helpful neighbors.

The current status of pregnant women’s awareness of social capital in disaster-affected areas was revealed. Continuous monitoring and support may be necessary to address this issue.(Disaster Med Public Health Preparedness. 2017;11:355–364)

This study aimed to clarify the correlation between the 2011 Great East Japan Earthquake and domestic violence (DV) against pregnant females after the disaster in Miyagi Prefecture, an area damaged by the earthquake and tsunami.

We analyzed 7600 pregnant females from June to December 2011. The incidence of physical and mental DV and the proportions in the inland, north coastal, and south coastal areas of Miyagi Prefecture and nationwide were calculated, and a chi-square test was conducted for comparison. The risk factors for DV were estimated with multivariate logistic regression analyses on a prefecture-wide basis.

The incidence levels for physical DV were found to be 5.9% in the north coastal area, which was significantly higher than in the inland area (1.3%, P=0.0007) and nationwide (1.5%, P<0.0001). There were no significant differences in the incidence of mental DV between the 3 areas in Miyagi Prefecture (inland 15.2%, north coast 15.7%, and south coast 18.8%) or nationwide (13.8%). Experiencing disease or injury in someone close and changes in the family structure were significantly associated with mental DV in Miyagi Prefecture.

Continuous monitoring and support for pregnant females may be necessary to address this issue in disaster-affected areas. (Disaster Med Public Health Preparedness. 2017;11:216–226)

The Great East Japan Earthquake of March 11, 2011 may have influenced the long-term health of those in the disaster area. It is important to collect current and future health information of the people living in the post-disaster area to provide appropriate health support and quality-oriented care. However, public perceptions of health and genomic studies in the Great East Japan Earthquake disaster area are still unknown.

A questionnaire survey was conducted in one town affected by the Great East Japan Earthquake and subsequent tsunami. The results of the questionnaire were tailed and the differences in responses to each question were assessed by sex and age.

In 284 eligible people (137 men, 147 women), almost all participants agreed to join a health survey investigating the adverse effects of the disaster, and over 80% of the total participants agreed to genomic analysis. Over 70% of the participants wanted to receive pharmacogenetic testing and to receive feedback on which medications were suitable or unsuitable for them.

Most people living in the disaster area are interested in health surveys. Most of the participants also showed interest in genomic analysis.

This study aimed to explore the correlation between the 2011 Great East Japan Earthquake and postpartum depression among perinatal subjects in the Miyako region of Iwate, an area damaged by earthquakes and tsunamis.

We retrospectively compared the percentages of women with scores ≥9 on the Japanese version of the Edinburgh Postnatal Depression Scale (EPDS) among 3 groups of women who gave birth prior to the disaster (before-disaster group: n=141), within 3 months after the disaster (within-3-months group: n=70), and 4-6 months after the disaster (4-6-months group: n=89) at the Iwate Prefectural Miyako Hospital. The risk factors for EPDS scores ≥9 were estimated with multivariate logistic regression analyses.

Compared with the before-disaster group, a significantly greater number of women in the within-3-months group had EPDS scores ≥9 at hospital discharge (31.4% versus 9.9%, P<.0001), whereas women in the 4-6-months group did not (10.1% versus 9.9%, P=.96). In both the after-disaster groups, the destruction of their home (adjusted odds ratio [AOR], 3.68; 95% confidence interval [CI], 1.46-9.26) and dissatisfaction with their living conditions (AOR, 3.02; 95% CI, 1.20-7.59) were significantly associated with EPDS scores ≥9.

An increase in postpartum depression was observed after the Great East Japan Earthquake among perinatal women. (Disaster Med Public Health Preparedness. 2015;9:307-312)

Adequate fruit and vegetable intake has been suggested to protect against colorectal cancer. However, several recent prospective studies have reported no association. We therefore examined the association between fruit and vegetable intakes and the risk of colorectal cancer in a prospective cohort study in Japan.

Between June and August 1990, 47 605 Japanese men and women completed a self-administered questionnaire, including a food-frequency questionnaire. We divided the subjects into quartiles based on their self-reported fruit and vegetable consumption. There were 165 colon cancer and 110 rectal cancer incidences identified during 7 years of follow-up, to the end of December 1997. We used Cox proportional hazards models to estimate the relative risk (RR) of developing colorectal cancer according to the level of fruit and vegetable consumption, applying adjustments for potential confounders.

No statistically significant association was observed between fruit and vegetable consumption and the risk of colorectal cancer. The multivariate RR of colon cancer in the highest quartile of fruit and vegetable intake compared with the lowest was 1.13 (95% confidence interval (CI) 0.73–1.75), the RR for vegetables alone was 1.24 (95% CI 0.79–1.95) and that for fruit alone was 1.45 (95% CI 0.85–2.47). The corresponding multivariate RRs for rectal cancer were 1.12 (95% CI 0.67–1.89), 1.14 (95% CI 0.67–1.93) and 1.41 (95% CI 0.73–2.73).

We found no association between the consumption of fruit and vegetables and the risk of colorectal cancer among the Japanese population.
