【目的】日本におけるパーキンソン病（PD）患者のヘスリテラシーを調査し，その実態を明らかにする．さらにPD患者のヘルスリテラシーがセルフマネジメントと健康関連Quality of life（HRQOL）にどのような影響を与えるのかを明らかにすることを目的とする．

【方法】PD患者を対象に自記式質問紙法を用いて横断研究を実施した．回収した203部のうち，182部を分析対象とした．調査項目は人口統計学的情報に加え，functional, communicative and critical health literacy，セルフマネジメント関連因子，HRQOLとしてParkinson’s disease questionnaire-8（PDQ-8）を測定した．

【結果】基本属性の平均（SD）は年齢71.95（8.45），罹病期間11.17（8.33），男性42.9％，女性57.1％であった．ヘルスリテラシーの平均（SD）は機能的ヘルスリテラシー2.76（.68），相互作用ヘルスリテラシー3.05（.60），批判的ヘルスリテラシー2.71（.68）であった．セルフマネジメントを従属変数とした重回帰分析の結果，機能的ヘルスリテラシーのみが症状のセルフマネジメント（β＝.24, p＝.006），社会生活のセルフマネジメント（β＝.23, p＝.005）と関連を認めた．PDQ-8SIとも機能的ヘルスリテラシーのみがセルフマネジメントスキルの影響を除いても関連を認めた（β＝-.19, p＝.013）．

【結論】機能的ヘルスリテラシーはPD患者のHRQOLに影響を与える可能性があり，ヘルスリテラシーのレベルを考慮したアプローチが必要である．

[Purpose] To examine the moisturizing effects of applying and spraying a moisturizer composed of a mixture of urea, glycerin, and purified water on dry skin in community-dwelling older adults.

[Methods] This before-after comparative design in quasi-experimental study included 8 adults aged 60 years and older. The stratum corneum hydration was measured using Mobile Moisture HP10-N®. First, both lower legs were allowed to acclimate to the environment for 15 min, after which the stratum corneum hydration was measured. Second, moisturizer was applied to one leg and sprayed on the other leg. Stratum corneum hydration was measured immediately after moisturizer use and 5, 15, 30, and 60 min after use.

[Results] Regarding moisturizing habit, it was found that 7 participants did not habitually moisturize. Skin dryness of the lower legs was observed in 6 participants. No differences were observed between the two methods in terms of the degree or duration of the moisturizing effect. Stratum corneum hydration significantly increased immediately after application and significantly decreased after 5 min for both methods.

[Conclusions] There was no difference in the moisturizing effects between applying and spraying. However, spraying is a simple procedure, it may lead to the development of a moisturizing habit.
