Fundamental Research on the Invention of Breast Support Underwear with a Focus on Women\u27s Comfort

The purpose of this study was to establish a system for measuring breast underling pressure, evaluate the degree of sustained underling pressure, and verify basic data on the breast lifting distance to improve it. We measured the lifting distance and force at which 24 adult women felt comfortable when their breasts were lifted with an uncovered cloth. The results revealed that the larger the breast size, the greater the pull-up distance and the wider the lifting distance perceived as comfortable. The validity of the measurement method in this study was determined to be useful for the measurement of breast ptosis pressure and breast ptosis position because the measurement was performed at least three times per participant, and the error was small. In the future, we would like to clarify the type of brassiere that supports the breast and gives women a sense of comfort

Education for appropriate seatbelt use required for early-phase pregnant women drivers.

Considerable numbers of pregnant women do not understand the correct way to use seatbelts; thus, they are inappropriately restrained when wearing seatbelts. To improve appropriate seatbelt wearing by pregnant women vehicle passengers, we examined their use by pregnant women drivers and the independent factors influencing appropriate use. We undertook a cross-sectional survey of 1,000 pregnant women in Shiga Prefecture, Japan. Among 774 returned questionnaires, we analysed those of 680 pregnant women who always wore a seatbelt. The mean participant age was 31.4 ± 5.0 years and mean gestational age 26.2 ± 8.2 weeks; 97.7% of subjects always wore a seatbelt; 86.9% wore a seatbelt correctly and 13.1% incorrectly. Multivariate analysis indicated that receiving information about correct seatbelt use (odds ratio, 2.25; P < 0.005) and gestational age (odds ratio, 1.06; P < 0.001) were significant independent factors for correct seatbelt use. Providing information about correct seatbelt use during the early term is required for pregnant women to protect both the mother and fetus

Effectiveness of aloe fomentation for nipple-related complications during the early puerperium period: a randomized, controlled, interventional study

Objective:Nipple-related complications are major factors that prevent breastfeeding for many new mothers. Hence, we tested the effects of aloe arborescens fomentation applied to the nipples as a treatment for nipple-related complications.Results:This study included 60 women who breastfed for the first time on day 1 after delivery. Every 24 h, all women breastfed six times and bottle-fed two times (at night). Women were classified into an intervention group (aloe arborescens fomentation) and a control group (no treatment). Aloe fomentation was applied after breastfeeding six times per day. We observed the nipples three times per day for 5 days after delivery. The most common nipple-related complication in this study was redness. A significant decrease was observed for women in the intervention group.

Common Pregnancy Complaints Can Lead to Motor Vehicle Collisions or Near-Miss Incidents

Pregnant women commonly report various health complaints during pregnancy, the occurrence of which is believed to cause human error. However, no study has examined the relationship between the occurrence of pregnancy complaints and the risk of motor vehicle collisions (MVCs). This study aimed to clarify the relationship between the frequency and severity of common pregnancy complaints and the occurrence of MVCs or near-miss incidents. We conducted a multicenter cross-sectional survey of 1000 pregnant women in Shiga Prefecture, Japan. The event group experiencing MVCs or near-miss incidents during pregnancy comprised 10.8% of respondents. The frequency of compression of the stomach or abdomen, tension and cramps in the lower abdomen, pelvic pain, irritability, depressed mood, distractedness, and hot flashes was significantly higher in the event group. The results of our multivariate logistic regression analysis revealed that tension and cramps in the lower abdomen, distractedness, and irritability were independent contributory factors to such events, with an odds ratio of 2.414, 1.849, and 1.746, respectively. Educating pregnant women to avoid driving when experiencing these symptoms would improve maternal and fetal safety

Changes in high school students’ perception of sexual education based on preconception care

This study examined the effect of sexual education, incorporating preconception care, through a text mining analysis. Between November 2018 and October 2019, we performed a cross-sectional study of 502 high school students in Japan. These two high schools had requested sexual education from midwives associated with Shiga University of Medical Science. The midwives conducted one 60–90-min presentation on sexual education at each school. After the intervention, an anonymous self-administered, paper-based questionnaire survey was administered to the students. Correspondence and cluster analyses were then performed using text mining software. After receiving sexual education taught by midwives, 50.1% of respondents answered that their sexual awareness and thoughts had ‘changed’ or ‘changed somewhat’. It became clear that students who felt that they had changed after taking sexual education also felt that it was important to think seriously about various things such as dating violence, sex, and life. On the other hand, among the students who answered that they did not experience any change in their sexual awareness and thinking, it became clear that this was owing to the content of the sexual education received at junior high school being similar to the current content (p < 0.05). The results of the correspondence and cluster analyses indicate that sexual education that includes instruction on preconception care can help raise students’ awareness, helping avoid unexpected pregnancies, and could possibly contribute to better reproductive health for both men and women (p < 0.05). The findings suggest that teaching preconception care is an important midwifery activity that will help improve the health of the next generation, including supporting the World Health Organization’s major goals of reducing perinatal and infant mortality rates

ニホン ニ オケル ニュウボウ シタギ ノ レキシテキ ヘンセン : ニュウボウ ケア ノ イミ オ フクム ブラジャー

【背景と目的】乳房ケアの担い手である助産師は、ケア用品としての乳房下着に関する研究に取り組んでこなかった。ブラジャーとしての定着とケア用品としての歴史的変遷を明らかとし、ブラジャーの意味について再考することを目的に文献研究に取り組んだ。【方法】2019年5月～9月、国立国会図書館デジタルコレクションにて関連書物を検索し、研究目的に該当する35文献を調査対象とした。【結果】乳房下着は、乳房を隠すことを目的に女性は着用していたが、社会進出によるライフスタイルの変化や洋装の定着により、乳房を美しく見せるための役割として変化していった。1800年頃(寛政12年頃)は、ブラジャーに乳房を支持する機能はなかったが、授乳期女性にとって、乳房の締め付けは乳汁産生と分泌を妨げることが理解されていた。1880年頃(明治13年頃)には、妊娠期女性のために、乳房を支えることは良いとされていたが、マタニティブラジャーが誕生したのは、70年後の1950年代(昭和25年)であった。【考察】女性が着用する乳房下着は、女性性の象徴として乳房を美しくみせるといった印象が時代とともに先行し、母乳栄養を行う女性のケア用品としての意味は、欠如していたことが示唆された。助産師として、授乳する女性のためのケア用品として、乳房変化に合わせた望ましいブラジャーの機能特性の見解を世に出すべく、研究に取り組んでいく必要性がある

Habitual dietary intake and glutamic acid in durable milk at one month postpartum

Glutamic acid (Glu), an umami component in human milk, has been suggested to play an important role in the prevention of allergies and infections in infants, but the relationship between mothers\u27 habitual diet and Glu in human milk is not clear. Therefore, we aimed to clarify the relationship between maternal dietary habits and Glu concentrations in durable milk during the first month postpartum in 41 lactating women using a cross-sectional prospective study. Metrics included habitual dietary intake at 1 month postpartum (Self-Reported Dietary History Questionnaire), Glu concentration in durable milk whey, and plasma at 1 month postpartum. There was no correlation between Glu concentration in plasma and durable milk Glu concentration at 1 month postpartum. Food items that were correlated with plasma and milk Glu concentrations were sparse in Glu or did not contain Glu; therefore, we could not determine the relationship between Glu concentrations in durable milk and maternal dietary intake. In addition, Glu concentration in durable milk was significantly higher among multipara than primipara and among mothers with a relatively high degree of physical activity. Although the study did not show that mothers\u27 habitual dietary intake affected milk Glu, Glu concentrations in durable milk were approximately 30 times higher than those found in plasma. Further research is needed to clarify the relationship between individual factors and milk or plasma Glu
