The purpose of this study was to identify correlates of physical activity behavior in a sample of rural, predominantly African American youth. Three hundred sixty-one fifth-grade students from two rural counties in South Carolina (69% African American, median age = 11 years) completed a questionnaire designed to measure beliefs and social influences regarding physical activity, physical activity self-efficacy, perceived physical activity habits of family members and friends, and access to exercise and fitness equipment at home. After school physical activity and television watching were assessed using the Previous Day Physical Activity Recall (PDPAR). Students were classified as physically active according to a moderate physical activity standard: two or more 30-min blocks at an intensity of 3 METs (metabolic equivalents) or greater, and a vigorous physical activity standard: one or more 30-min blocks at an intensity of 6 METs or greater. According to the moderate physical activity standard, 34.9% of students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and exercise equipment at home to be significant correlates of low activity status. According to the vigorous physical activity standard, 32.1% of the students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and self-efficacy with respect to seeking support for physical activity to be significant correlates of low activity status. In summary, gender and the amount of television watching were found to be the most important correlates of physical activity in rural, predominantly African American youth.
本研究旨在确定以非裔美国人为主的农村青少年样本中身体活动行为的相关因素。来自南卡罗来纳州两个农村县的361名五年级学生(69%为非裔美国人,中位年龄 = 11岁)完成了一份问卷,该问卷旨在测量关于身体活动的信念和社会影响、身体活动自我效能、对家庭成员和朋友身体活动习惯的认知,以及家中锻炼和健身设备的可及性。放学后的身体活动和看电视情况通过前一天身体活动回忆法(PDPAR)进行评估。根据适度身体活动标准(强度为3代谢当量或更高,两个或更多30分钟时间段)和剧烈身体活动标准(强度为6代谢当量或更高,一个或更多30分钟时间段),学生被分类为身体活跃。根据适度身体活动标准,34.9%的学生被分类为低活动水平。多变量分析显示年龄、性别、看电视情况和家中的健身设备是低活动状态的显著相关因素。根据剧烈身体活动标准,32.1%的学生被分类为低活动水平。多变量分析显示年龄、性别、看电视情况以及在寻求身体活动支持方面的自我效能是低活动状态的显著相关因素。总之,性别和看电视时间被发现是农村以非裔美国人为主的青少年身体活动最重要的相关因素。
