BACKGROUND
Sedentary behaviors such as TV viewing are associated with childhood obesity, while physical activity promotes healthy weight. The role of the home environment in shaping these behaviors among youth is poorly understood. The study purpose was to examine the reliability of brief parental proxy-report and adolescent self-report measures of electronic equipment and physical activity equipment in the home and to assess the construct validity of these scales by examining their relationship to physical activity, sedentary behavior, and weight status of children and adolescents.
METHODS
Participants were adolescents (n = 189; mean age = 14.6), parents of adolescents (n = 171; mean age = 45.0), and parents of younger children (n = 116; parents mean age = 39.6; children's mean age = 8.3) who completed two surveys approximately one month apart. Measures included a 21-item electronic equipment scale (to assess sedentary behavior facilitators in the home, in the child or adolescent's bedroom, and portable electronics) and a 14-item home physical activity equipment scale. Home environment factors were examined as correlates of children's and adolescents' physical activity, sedentary behavior, and weight status after adjusting for child age, sex, race/ethnicity, household income, and number of children in the home.
RESULTS
Most scales had acceptable test-retest reliability (intraclass correlations were .54 - .92). Parent and adolescent reports were correlated. Electronic equipment in adolescents' bedrooms was positively related to sedentary behavior. Activity equipment in the home was inversely associated with television time in adolescents and children, and positively correlated with adolescents' physical activity. Children's BMI z-score was positively associated with having a television in their bedroom.
CONCLUSIONS
The measures of home electronic equipment and activity equipment were similarly reliable when reported by parents and by adolescents. Home environment attributes were related to multiple obesity-related behaviors and to child weight status, supporting the construct validity of these scales.
背景
久坐行为，如看电视，与儿童肥胖有关，而身体活动则有助于保持健康体重。家庭环境在塑造青少年这些行为方面的作用尚未得到充分了解。本研究旨在检验青少年父母代报告和青少年自我报告的家庭电子设备和体育活动设备的简短测量工具的可靠性，并通过考察这些量表与儿童和青少年身体活动、久坐行为和体重状况的关系来评估这些量表的结构效度。
方法
参与者包括青少年（n=189；平均年龄=14.6 岁）、青少年的父母（n=171；平均年龄=45.0 岁）和年龄较小的儿童的父母（n=116；父母平均年龄=39.6；儿童平均年龄=8.3），他们大约在一个月的时间内完成了两次调查。测量包括 21 项电子设备量表（评估家庭中、青少年卧室中以及便携式电子设备中的久坐行为促进因素）和 14 项家庭体育活动设备量表。在调整了儿童年龄、性别、种族/民族、家庭收入和家中儿童人数等因素后，考察家庭环境因素与儿童和青少年的身体活动、久坐行为和体重状况的相关性。
结果
大多数量表的重测信度都较好（组内相关系数为.54-.92）。父母和青少年的报告呈正相关。青少年卧室中的电子设备与久坐行为呈正相关。家庭中的活动设备与青少年和儿童的看电视时间呈负相关，与青少年的身体活动呈正相关。儿童的 BMI z 分数与卧室里有电视呈正相关。
结论
当由父母和青少年报告时，家庭电子设备和活动设备的测量工具具有相似的可靠性。家庭环境属性与多种肥胖相关行为和儿童体重状况相关，支持这些量表的结构效度。
