タイトル: Relationship between menstrual cycle and glucose metabolism in healthy young Japanese women 著者: Kiho, Miyoshi; Yuuki, Hama; Miyawaki, Takashi 抄録: Background: The menstrual cycle, which is regulated by estrogen and progesterone, may influence glucose metabolism. Previous findings have remained inconsistent, and few studies have focused on Japanese women.Methods: We investigated seven healthy young Japanese women with regular menstrual cycles (25–38 d). Each participant underwent a 75-g oral glucose tolerance test (OGTT) during both the follicular and luteal phases as determined by self-reported cycles. Fasting and post-load glucose and insulin levels were measured at 0, 30, 60, and 120 min. Estrogen, progesterone and HbA1c levels were also measured. Glucose tolerance was classified according to the Japan Diabetes Society criteria, and indices of insulin resistance (HOMA-IR), β-cell function (HOMA-β), and the insulinogenic index were evaluated.Results: Estrogen and progesterone levels were significantly higher during the luteal phase than those during the follicular phase. Thirty minutes after glucose loading, plasma glucose values were high during the luteal phase (P=0.02), whereas insulin showed a tendency towards increasing values at 30 and 120 min (P=0.06). Although no significant differences were found in fasting indices of HOMA-IR or HOMA-β, the insulinogenic index was significantly lower during the luteal phase (P=0.03) compared to that during follicular phase.Conclusions: The luteal phase is associated with impaired postprandial glucose handling and reduced early insulin secretion. Therefore, menstrual cycle phase should be considered when evaluating glucose metabolism in young premenopausal Japanese women.

タイトル: 石川県奥能登地方 災害ボランティア活動記「被災された方々との関わりから感じたこと」 著者: 安田, 玲伊子; 坂口, 晴香; 毛利, 美結 抄録: 2024年1月1日，石川県能登半島で地震が発生した。私たちは京都女子大学家政学部食物栄養学科に所属し，管理栄養士を志している学生として，震災発生後から食を通じた支援に微力ながらも尽力したいとの思いが強くあった。2025年8月22～26日，石川県奥能登にて災害ボランティア活動に参加した。奥能登は幾度となく自然災害に見舞われ，震災後の過疎化が急速に進行している。それでもなおこの地を離れず生き続ける人々，その多くは高齢者である。住み慣れた家には倒壊の恐れがあるため戻れず，見知らぬ人々と肩を寄せ合う避難所や，ようやく与えられた仮設住宅で暮らす日々が続いている。心と身体の健康を思えば，食を通じて人々を支える管理栄養士の存在意義はきわめて大きいと感じた。今回，真宗大谷派 奥能登ボランティアセンターが主催する「コミュニティ居酒屋」に参加した。この活動では人と人との繋がりをとても重要視されており，被災された方々と食事を共にすることで，普段は耳にすることのできない貴重なお話を伺うことができた。食を介した語りの場は気持ちを和やかにし，これまで話すことの出来なかった現状や震災当時の出来事を共有する機会となることが分かった。また，被災者自身が状況を把握し整理する助けにもなる機会を食事と共に提供することが，被災者支援の一つとなることを学んだ。管理栄養士は災害時の栄養確保に加え，心理的支援や地域の防災力強化にも寄与する専門職として，その多面的役割の重要性が示唆された。From August 22 to 26, 2025, We participated in volunteer activities in Oku-Noto area, Ishikawa Prefecture, Japan. Oku-Noto area has been suffering from rapid depopulation ever since the numerous natural disasters.However, many people continued to live there, and the fact is almost all those are elderly. In the evacuation center,they slept next to the strangers, even they got temporary housing though those people lost their home either going back home and living is too risky to collapse. Dietary management is one of the main roles of the registered dietitian,on top of that caring for health physically and mentally is extremely important. The “Community Izakaya” hosted by the Oku-Noto Volunteer Center provides an opportunity to connect the distressed people. Sharing a table for eating made people in Oku-Noto feel relaxed to pull out their real feelings so that we were able to hear their stories that we would never reach out normally. Providing a place and opportunity for disaster victims to talk about their circumstances allows them to adjust their own situation and share with others. We learned that this can be a support for disaster victims. We believe that Registered dietitians need to fulfill their role multifunctionally, not only by ensuring nutritional intake during disasters, but also in charge of contributing psychological support to strengthen the local community for preventing a future natural disaster.

タイトル: 日本人若年女性における月経周期と月経随伴症状がもたらす食行動および食嗜好の変化 著者: 三好, 希帆; 明保能, 舞子; 藤原, 舞香; 川添, 禎浩; 宮脇, 尚志 抄録: 【背景】月経周期は心身の健康や生活に影響を及ぼし，月経随伴症状は食行動とも関連することが示唆されているものの，月経随伴症状に対する食事療法や食行動に関する報告は乏しい。本研究では，月経周期と月経随伴症状および食行動との関連を検討し，月経随伴症状に対する食事療法を検討する際の参考とすることを目的とした。【方法】日本の女子大学生110名（19～21歳）を解析対象とし，2023年度に質問紙調査を実施した。調査項目は，属性，月経随伴症状（PMDD/PMS評価尺度：PSST，月経随伴症状日本語版：MDQ），摂食障害（SCOFF），月経周期に伴う食行動・食嗜好の変化の調査（自由記述式）であり，自由記述はテキストマイニングで解析した。【結果】対象者のBMIの中央値は20.0㎏/m2であった。MDQ分類では，正常群は31.8%，月経前症状有群は32.7%，月経前後ともに症状有群は35.5%であった。PSSTでは，PMS軽症が66.4%，中等症が16.4%，重症（PMDD）が17.3%であり，83%が月経前に食欲増加および特定の飲食品を欲していた。「月経前に食べたくなるもの」のテキストマイニングの結果，出現回数の最多語は「甘いもの」（53回），次いで「チョコレート」（27回）であり，高糖質・高脂質食品が特徴的であったが，PSSTやMDQ，摂食障害との関連は認められなかった。【結論】月経前には食欲や食行動が変化する者が多く，特に高糖質・脂質食品やチョコレートへの嗜好が強まる可能性が示唆され，それらの成分が月経周期との関連がある可能性が考えられた。Background: The menstrual cycle influences both physical and mental health. Although menstrual-related symptoms have been suggested to be associated with eating behaviors, few past studies have examined dietary interventions or eating patterns related to the menstrual cycle. This study aimed to investigate the associations between the menstrual cycle, menstrual-related symptoms, and eating behaviors to provide insights for dietary management.Methods: We analyzed 110 female Japanese university students aged 19-21 years using a questionnaire survey conducted in 2023. Items included demographics, menstrual-related symptoms [Premenstrual Symptoms Screening Tool (PSST), Menstrual Distress Questionnaire (MDQ, Japanese version)], disordered eating (SCOFF), and changes in eating behavior and food preferences across the cycle (open-ended responses). Free-text responses were analyzed using text mining.Results: The median body mass index was 20.0 kg/m². The MDQ classified 31.8% as normal, 32.7% as premenstrual-symptom, and 35.5% as pre- and post-menstrual symptom groups. The PSST identified 66.4% with mild premenstrual syndrome (PMS), 16.4% with moderate PMS, and 17.3% with severe PMS (PMDD). Overall, 83% of the participants reported increased appetite or cravings before menstruation. Text mining revealed “sweets” (53 mentions) and “chocolate” (27 mentions) as the most frequent terms, indicating a preference for high-carbohydrate, high-fat foods. No significant associations were found between food preferences and the PSST, MDQ, or SCOFF.Conclusion: Many young Japanese women reported increased appetite and specific cravings before menstruation, particularly for chocolate and other high-carbohydrate, high-fat foods. These findings suggest potential links between the menstrual cycle and dietary components, with implications for cycle-based dietary management.

タイトル: 短時間・低強度の運動が身体組成及び体力に与える影響 : 健常若年女性におけるパイロット研究 著者: 橘田, 薫; 樋口, 友紀; 宮脇, 尚志; 梶山, 静夫; 梶山, 真太郎; 今井, 佐恵子 抄録: 目的：2型糖尿病患者に対するパイロット研究として，若年健常女性を対象に短時間かつ低強度の食後運動の身体組成及び体力に与える影響を調べた。方法　研究1：若年健常女性18名を対象に，朝食及び夕食30分後の運動を2か月間継続し，介入前後の身体組成，握力，5回椅子立ち上がりテストのタイムの変化を調べた。握力を鍛えるためハンドグリップトレーニングを1日朝夕2回に加え，朝食後は有酸素運動（ラジオ体操第一・第二）を週3回以上，夕食後はレジスタンス運動（スクワット，フロントランジ，サイドランジ）を週3日程度実施した。運動強度は30%HRRを目標とした。研究2：研究1に参加した18名のうち9名は休暇期間の後さらに2か月間同様の運動を実施し，再介入後の体力テスト，体組成を調べた。運動強度はハンドグリップの強度およびレジスタンス運動の回数を増やして調整した。結果：各運動の遵守率は研究1及び2いずれも80%以上であった。介入2か月後（研究1）の5回椅子立ち上がりテストのタイムは介入前と比較して有意に改善したが，研究1, 2ともに握力に有意な変化は認められなかった。一方で，骨格筋指数は低下がみられた。結論：有酸素運動とレジスタンス運動を組み合わせた運動の介入の結果，短時間・低強度の運動であっても下肢筋機能の向上につながることが示唆された。Objective: As a pilot study for individuals with type 2 diabetes this study investigated the effects of short-duration, low-intensity postprandial exercise on body composition and physical fitness in healthy young women.Methods Study 1: Eighteen young women performed postprandial exercise 30 minutes after breakfast and dinner for two months. Changes in body composition, handgrip strength, and the time required for a five-time sit-to-stand test were evaluated before and after the intervention. To improve grip strength, handgrip training was performed twice daily. In addition, aerobic exercise (Radio calisthenics 1 & 2) was conducted at least three times per week after breakfast, and resistance exercises were performed three times per week after dinner. Exercise intensity was set at 30% of heart rate reserve. Study 2: After the vacation period, 9 of the 18 participants from Study 1 continued the same exercise regimen for an additional two months, and their physical fitness and body composition were re-evaluated. In the latter half, exercise intensity was adjusted by increasing handgrip resistance and the number of repetitions for resistance training.Results: Exercise adherence exceeded 80% in both studies. The time for the five-time sit-to-stand test significantly improved after 2 months compared to baseline in Study 1. However, no significant changes were observed in handgrip strength in both Study 1 and 2. In contrast, skeletal muscle mass index showed a decrease.Conclusion: These findings suggest that even short-duration, low-intensity combined aerobic and resistance exercise can improve lower limb muscle function in healthy young women.
