Abstract

<p><b>目的</b> 本研究では,若年層(25-49歳)と高年層(65-84歳)における世代内/世代間交流ならびにそれらの組み合わせと精神的健康との関連について検討することを目的とした。</p><p><b>方法</b> 2016年に地域住民を対象とした質問紙調査を実施した。有効回答を得た若年層3,334人(回収率24.6%)および高年層3,116人(回収率46.0%)を本研究の解析対象者とした。精神的健康については,WHO-5を用いて,合計点数が13点未満もしくはいずれかの設問に対し1点以下の回答をした者を「不良な健康状態」と判定した。世代内/世代間交流については,親族や仕事関係の人を除いた者との交流頻度を調査した。若年層においては「20-40代」,高年層においては「70代以上」との交流を「世代内交流」,若年層における「70代以上」,高年層における「20-40代」との交流を「世代間交流」とした。また,これらの組み合わせとして両世代との交流がある者は「両世代交流あり」,両世代とも交流がない者を「交流なし」とした。統計解析においては,精神的健康を目的変数,世代内/世代間交流を説明変数,性別,年齢,最終学歴,婚姻状態,同居者,主観的経済状況,地域活動への参加,就労,健康度自己評価,手段的日常生活動作能力を調整変数としたロジスティック回帰分析を行った。</p><p><b>結果</b> 若年層3,334人のうち,精神的健康が良好な者が61.5%,「世代内交流あり」は51.3%,「世代間交流あり」は21.9%,「両世代交流あり」が16.5%,「交流なし」が42.7%であった。一方,高年層3,116人のうち,精神的健康が良好な者は65.8%,「世代内交流あり」は67.9%,「世代間交流あり」は34.3%,「両世代交流あり」は29.9%,「交流なし」は21.1%であった。ロジスティック回帰分析の結果,いずれの世代においても「世代内交流あり」,「世代間交流あり」は交流していない者と比較して精神的健康状態が良好であった。世代内/世代間交流の組み合わせと精神的健康との関連では,両世代において,「世代内交流のみ」と比較して「交流なし」は精神的健康が有意に劣り,「両世代交流あり」は良好であることが示された。</p><p><b>結論</b> 若年層と高年層において世代内交流ならびに世代間交流が良好な精神的健康と関連し,両世代と交流している者はさらに精神的健康が良好であることが示唆された。</p>

<p><b>Objective</b> The purpose of this study was to examine the relationship between intra- and inter-generational exchange and mental health among young adults aged 25-49 years and older adults aged 65-84 years.</p><p><b>Methods</b> In 2016, a community-based, cross-sectional survey was conducted. A total of 3,334 young adults (valid response rate: 24.6%), and 3,116 older adults (valid response rate: 46.0%) completed the survey and were included in the analysis. Their mental health was evaluated using the World Health Organization-Five Well-Being Index (WHO-5), and those who scored under 13 or scored less than one on any item were considered to have poor mental health. To evaluate the intra- or inter-generational exchange, participants were asked about their frequency of interaction with people aged 20-49 years or aged ≥70, excluding family and co-workers. Young adults who interacted with people aged 20-49 years or older adults who interacted with people ≥70 were classified as "having intra-generational exchange," while young adults who interacted with people ≥70 years or older adults who interacted with people aged 20-49 years were classified as "having intergenerational exchange." Therefore, individuals who interacted with both generations were classified as "having multi-generational exchange," and those who did not interact with any generation were categorized as "no exchange." We conducted a logistic regression analysis that included mental health as a dependent variable, intra- and inter-generational exchange as independent variables, and gender, age, educational attainment, marital status, living situation, subjective economic status, social participation, employment, self-rated health, and Instrumental Activity of Daily Living as covariates.</p><p><b>Results</b> Of the 3,334 young adults, 61.5% were mentally healthy, 51.3% had intra-generational exchange, 21.9% had inter-generational exchange, 16.5% had multi-generational exchange, and 42.7% did not have any exchange. Of the 3,116 older adults, 65.8% were mentally healthy, 67.9% had intra-generational exchange, 34.3% had inter-generational exchange, 29.9% had multi-generational exchange, and 21.1% did not have any exchange. A logistic regression analysis revealed that "having intra-generational exchange" and "having intergenerational exchange" were significantly related to better mental health in both young adults (intra-generational; Odds ratios (OR) 1.19, 95% confidence intervals (CI) 1.10-1.30: inter-generational; OR 1.13, 95% CI 1.03-1.25) and older adults (intra-generational; OR 1.15, 95% CI 1.02-1.29: inter-generational; OR 1.46, 95% CI 1.30-1.65). Therefore, "having multi-generational exchange" was more strongly related to better mental health compared with "only having intra-generational exchange."</p><p><b>Conclusion</b> Among young and older adults, intra- and inter-generational exchange were related to better mental health, and multi-generational exchange showed the strongest relationship with better mental health.</p>
