背景了解影响体育活动行为的因素是重要的，在针对青少年的干预方案的设计。采用前瞻性研究设计，在202名农村儿童（主要是非洲裔美国儿童）中确定剧烈体力活动（VPA）（大于或等于6 MET）和中度和剧烈体力活动（MVPA）（大于或等于3 MET）的预测因子。在五年级，通过问卷调查对选定的体育活动的社会认知决定因素进行了评估。通过一年后的前一天体力活动回忆来评估六年级参与VPA和MVPA的情况。对于女孩来说，参加社区体育活动、克服障碍的自我效能、学校体育课的享受、种族（白色>黑色）和对母亲活动水平的感知（活跃与不活跃）是VPA的重要预测因素。对于MVPA，参与社区体育和克服障碍的自我效能是显着的预测因子。对男生而言，克服障碍的自我效能感是VPA的唯一显著预测因子，而对活动结果和参与社区体育的信念是MVPA的显著预测因子。社会认知结构，如体育活动自我效能，获得社区体育活动网点，以及积极的信念，体育活动的结果是未来的体育活动行为的重要预测因素在农村，主要是非洲裔美国儿童。(C)北京：科学出版社.
Background. Understanding the factors that influence physical activity behavior is important in the design of intervention programs targeted at youth.Methods. A prospective study design was used to identify the predictors of vigorous physical activity (VPA) (greater than or equal to 6 METs) and moderate and vigorous physical activity (MVPA) (greater than or equal to 3 METs) among 202 rural, predominantly African-American children. Selected social-cognitive determinants of physical activity were assessed via questionnaire in the fifth grade. Participation in VPA and MVPA was assessed via the previous day physical activity recall 1 year later in the sixth grade.Results. For girls, participation in community sports, self-efficacy in overcoming barriers, enjoyment of school physical education, race (white > black), and perception of mother's activity level (active vs inactive) were significant predictors of VPA. For MVPA, participation in community sports and self-efficacy in overcoming barriers were significant predictors. For boys, self-efficacy in overcoming barriers was the only significant predictor of VPA, while beliefs regarding activity outcomes and participation in community sports were significant predictors of MVPA.Conclusion. Social-cognitive constructs such as physical activity self-efficacy, access to community physical activity outlets, and positive beliefs regarding physical activity outcomes are important predictors of future physical activity behavior among rural, predominantly African-American children.
