成人市民を対象とした公開講座の短期的効果の検証

The Short-term Effect of Open College for Adult Citizens

要旨

目的：成人市民を対象として健康的なライフスタイルの獲得を目指した公開講座を実施し，参加者の健康に対する意識や行動変容に及ぼす短期的な効果を検証した．

方法：対照群を置かない前後比較デザインとした．公募により募った35名を対象として，週1回の公開講座を5週連続で実施した．効果指標には日本語版健康増進ライフスタイルプロフィールII（JLV-HPLP II），健康関連QOL（SF-8）を用い，介入の前後3時点において質問紙調査を行った．

結果：研究協力に同意が得られた32名を分析対象とした．一般線形混合モデルを用いて，一元配置の反復測定による分散分析を行った結果，全講座終了直後の時点において有意差が認められた下位尺度項目は，JLV-HPLP IIの総合，下位尺度の健康意識，精神的成長，身体運動，栄養，SF-8の全体的健康感であった．

結論：5週連続で実施した公開講座は，参加者の健康に対する意識と健康的な行動変容に対して短期的な効果をもたらすことが示唆された．

Objectives: In this study, we aimed to examine the short-term effects of open college on health awareness and behavioral change for healthy lifestyles.

Methods: This was an uncontrolled before-and-after trial of adult participants invited by open recruitment. The open college were held weekly for five weeks, with questionnaire surveys provided at three points for examining the effect of the intervention. Two scales were used for measuring the outcomes: the Japanese Language Version of the Health-Promoting Lifestyle Profile (JLV-HPLP II) and the Health-Related Quality of Life Short Form (SF-8).

Results: In total, 32 out of 35 approached individuals agreed to complete the surveys. Findings of one-way repeated measure analysis of variance, using general linear modelling, indicated significant differences in several subscales. In the JLV-HPLP II, differences were present in the total score as well as in the following elements: health responsibility, spiritual growth, physical activity, and nutrition. On the contrary, we noted only a difference in the general health element of the SF-8.

Conclusion: These results suggest that open college had a positive short-term effect on health awareness and the requirement for behavioral change for achieving a healthy lifestyle among participants.
