To identify and evaluate the trend of meal-skipping rates among Korean adolescents with their contributing causes and the influence of household income level on meal skipping.
Using 2008, 2010, and 2012 data from the Korea Youth Risk Behavior Web-based Survey of 222 662 students, a cross-sectional study with subgroup analysis was performed. We calculated odds ratios for skipping each meal 5 or more times in a week by household socio-economic status using a multiple logistic regression model. The secular change in the meal-skipping rates by the students' family affluence scale was analyzed by comparing the meal-skipping students within each subgroup and odds ratios for the same event over time.
Through 2008 to 2012, most of the meal-skipping rates generally showed a continuous increase or were almost unchanged in both sexes, except for breakfast skipping in several subgroups. Students in low-income households not living with both parents had the highest meal-skipping rates and odds ratios for frequent meal skipping. In a time-series subgroup analysis, the overall odds ratios for the same event increased during 2008 to 2012, with a slight reduction in the gap between low and higher income levels with regard to meal skipping during 2010 to 2012.
Household socio-economic status and several other factors had a significant influence on Korean adolescent meal-skipping rates. Although the gap in eating behavior associated with household socio-economic differences is currently decreasing, further study and appropriate interventions are needed.
确定并评估韩国青少年不规律就餐率的趋势及其成因，以及家庭收入水平对不规律就餐的影响。
利用韩国青少年风险行为网络调查2008年、2010年和2012年的数据，对222662名学生进行了横断面研究及亚组分析。我们使用多元逻辑回归模型，按家庭社会经济状况计算一周内每餐跳过5次及以上的比值比。通过比较各亚组内不规律就餐的学生以及同一事件随时间变化的比值比，分析了学生家庭富裕程度量表中不规律就餐率的长期变化。
从2008年到2012年，除了几个亚组中的不吃早餐情况外，大多数不规律就餐率在两性中总体呈持续上升或几乎不变。父母不全的低收入家庭学生不规律就餐率最高，频繁不规律就餐的比值比也最高。在时间序列亚组分析中，同一事件的总体比值比在2008年至2012年期间有所增加，在2010年至2012年期间，不规律就餐方面低收入和高收入水平之间的差距略有缩小。
家庭社会经济状况和其他几个因素对韩国青少年不规律就餐率有显著影响。尽管目前与家庭社会经济差异相关的饮食行为差距正在缩小，但仍需要进一步研究和采取适当干预措施。
