目標：探討不健康飲食行為與飲食偏好之於兒童與青少年的憂鬱情況相關性。方法：本研究以台灣北部及中部549位10－13歲的國中小學童為研究樣本。採用生活調適問卷（Center forEpidemiologic Studies Depression Scale），針對學童進行憂鬱情況分析，研究對象將分為憂鬱（分數＞21分）、中度憂鬱（分數15-21），及正常（分數＜15）族群。飲食行為內容包含不規律飲食、不良飲食經驗、不健康飲食習慣和飲食偏好。分組依據採用卡方檢定和ANOVA檢定，並以羅吉斯回歸檢定飲食行為與憂鬱情況的關聯性。結果：不健康的飲食習慣在國中小學童中相當盛行，最低由47.6%有攝取宵夜之習慣至高達70.5%攝取含糖飲品，且在平均在一周內有3.1餐為不規律飲食。卡方檢定的結果指出，憂鬱組（N=71, 14.4%）相較於中度憂鬱（N=77, 14.6%）與正常（N=379, 71.9%）組，有更不規律的飲食（p=0.005）、不健康的飲食習慣（P＜0.05，分項中宵夜攝取及含糖飲料攝取例外）及不良飲食經驗（p＜0.05，分項中僅食慾被零食影響例外）。在控制性別、年齡、地區下，羅吉斯回歸顯示隨著不健康飲食習慣與的項目累計，會使憂鬱或中度憂鬱的風險上升（ORadj：2.17-6.33）；相同控制背景之下，不良飲食經驗也同樣增加憂鬱的風險（ORadj：1.79-16.5）此外，若學童對蔬菜有較不佳的偏好，也會顯示與憂鬱情況有正相關（p=0.018）。結論：不健康的飲食行為與青少年的憂鬱情況呈現正相關，同時也是憂鬱情況的風險因子。此結果顯示，應更加重視學童飲食行為的改善，以遏止日後青少年憂鬱情況的盛行。

Objectives: Depression is prevalent in children and adolescents. We investigated whether unhealthy eating habits and eating preferences are associated with depression in Taiwanese youth. Methods: 549 students aged 10-13 years were enrolled from elementary and junior high schools in Taiwan. Using the Center for Epidemiologic Studies Depression Scale, three groups of depression were defined: depression (a score＞21), moderate depression (a score between 15-21) and normal (a score＜15) groups. We assessed irregular meal time, bad eating experiences, unhealthy eating habits and dietary preferences as their eating behaviors. Chi-square or ANOVA was used for group comparisons. Multivariate logistic regression was used to examine the relationship between eating behaviors and depression. Results: Unhealthy eating habits were common, ranged from 47.6% (midnight snack eating) to 70.5% (sugared beverages drinking). Taiwanese youth had on average 3.1 times per week of having irregular meal time. Depression group (N=71, 14.4%) reported to have more irregular eating meal time (p=0.005), unhealthy eating habits (p＜0.05 except for snack eating and sugar beverages drinking), and bad eating experiences to influence appetites (p＜0.05 except for appetite influenced by snack) than moderate depression (N=77, 14.6%) and normal (N=379, 71.9%) groups. The risk of depression or moderate depression increased with higher numbers of unhealthy eating habits (OR_(adj) ranged from 2.17-6.33) and bad eating experiences to influence appetites (OR_(adj) ranged from 1.79-16.5), with the irregular eating behavior subgroup showed a trend for a higher risk on depression. Additionally, students who had less preference for vegetables tended to be more depressed (p= 0.018). Conclusions: Commonly observed unhealthy eating behaviors are associated with higher risk of depression in youths. Interventions toward healthy eating behaviors could be considered as potential promoting strategies to reduce the burden of depression among children and adolescents.
