摘要:
目的 探讨银川市大学生24 h活动时间分配的潜在分类及其与主动健康水平的关系,为优化活动时间分配,提升主动健康水平提供参考。 方法 于2024年11月18日—12月6日,采用分层整群随机抽样方法抽取银川市全日制本科院校的2 422名大一至大二年级学生为研究对象,采用中国大学生24 h活动行为问卷(24 h MBQ)和主动健康行为量表调查大学生24 h活动时间分配现状、评估主动健康水平,通过潜在剖面分析(LPA)判别活动类别,通过二元Logistic回归分析其与大学生主动健康水平的关联性。 结果 有1 087名(44.9%)大学生具备主动健康水平,不同年龄、年级、办学性质、生源地、学科类别大学生主动健康具备率差异均有统计学意义(χ2值分别为22.03,7.65,25.50,10.12,43.44,P值均<0.01);不同性别、年龄、年级、生源地、办学性质、学科类别大学生24 h活动时间分布差异均有统计学意义(t/Z/H/F=-5.70~111.39,P值均<0.05)。24 h活动时间分配模式可分为学屏双高型(6.9%)、低耗休眠型(8.8%)、轻度活跃型(67.8%)和高能动态型(16.4%)4种。不同年龄、办学性质和学科类别下大学生活动时间分配类别分布差异均有统计学意义(χ2=15.52~108.46,P值均<0.05)。以高能动态型为参照组,轻度活跃型(OR=0.39,95%CI=0.31~0.50)、低耗休眠型(OR=0.10,95%CI=0.06~0.15)和学屏双高型(OR=0.03,95%CI=0.02~0.07)大学生具备较低的主动健康水平(P值均<0.01)。 结论 银川市大学生24 h活动时间分配类别存在明显异质性,不同活动类别均与主动健康水平存在关联。 Abstract:Objective To explore the potential classification of 24-hour activity time allocation among college students in Yinchuan and its association with active health levels, so as to provide references for optimizing activity time allocation to enhance active health levels. Methods From November 18 to December 6, 2024, a stratified cluster random sampling method was used to select 2 422 first- and second-year college students from full-time undergraduate institutions in Yinchuan. The Chinese College Students' 24-hour Movement Behaviors Questionnaire (24 h MBQ) and Active Health Behavior Scale were used to assess 24-hour activity time allocation and evaluate active health levels. Latent profile analysis (LPA) was employed to categorize activity types, and a binary Logistic regression analysis was conducted to analyze the relationship between active health levels and activity types. Results A total of 1 087 students (44.9%) were found of meeting active health standards, and significant statistical differences were found in active health levels across different genders, grades, academic qualities, sources of origin and academic categories (χ2=22.03, 7.65, 25.50, 10.12, 43.44, all P < 0.01). Moreover, significant statistical differences could also be found among college students' 24-hour activity time across different genders, ages, grades, sources of origin, academic qualities, and academic categories (t/Z/H/F=-5.70-111.39, P < 0.05).The 24-hour activity time allocation was classified into four types: academic high (6.9%), low activity rest (8.8%), light activity (67.8%), and high activity dynamic (16.4%). Significant statistical differences were observed in activity time allocation categories across different ages, academic qualities and academic categories (χ2=15.52-108.46, all P < 0.05). Using the high activity dynamic type as a reference, the light activity type (OR=0.39, 95%CI=0.31-0.50), low activity rest type (OR=0.10, 95%CI=0.06-0.15), and academic high type (OR=0.03, 95%CI=0.02-0.07) had lower active health levels among college students (all P < 0.01). Conclusion There is a significant difference in 24-hour activity time allocation among college students in Yinchuan, and different activity types are associated with active health levels. -
