Despite the negative health effects of too much sitting, the majority of adults are too sedentary. To develop effective interventions, insight is needed into home environmental correlates of adults' sedentary behaviors, and into the susceptibility of population subgroups to these home environmental cues. In total, 559 Flemish adults reported socio-demographics, weight and height, home environmental factors and domain-specific sedentary behaviors. Generalized linear modeling was conducted to examine main associations between home environmental factors and domain-specific sedentary behaviors, and to test the moderating role of socio-demographics and BMI on these associations. In case of significant interactions, stratified analyses were performed. Results showed that, among those who did use a computer/laptop during the last week, a one-unit increase in the number of computers or laptops was associated with 17% (OR = 1.17; 95% CI = 1.02, 1.34) and 24% (OR = 1.24; 95% CI = 1.08, 1.43) more minutes computer time per day, respectively. The proximity of the remote controller ( < 0.001) and the number of televisions ( = 0.03) were positively associated with television time, and the number of motorized vehicles (95% CI = 0.001, 0.12) was positively associated with the odds of participation in transport-related sitting time. The latter two associations were moderated by BMI, with significant positive associations limited to those not overweight. To conclude, home environmental factors were associated with domain-specific sedentary behaviors, especially in healthy weight adults. If confirmed by longitudinal studies, public health professionals should encourage adults to limit the number of indoor entertainment devices and motorized vehicles.
尽管久坐对健康有负面影响，但大多数成年人久坐不动。为了制定有效的干预措施，需要深入了解成年人久坐行为与家庭环境的相关性，以及不同人群亚组对这些家庭环境线索的易感性。共有559名弗拉芒成年人报告了社会人口统计学特征、体重和身高、家庭环境因素以及特定领域的久坐行为。采用广义线性模型来检验家庭环境因素与特定领域久坐行为之间的主要关联，并检验社会人口统计学特征和体重指数（BMI）对这些关联的调节作用。若存在显著交互作用，则进行分层分析。结果显示，在上周使用过电脑/笔记本电脑的人群中，电脑或笔记本电脑数量每增加一个单位，每天使用电脑的时间分别增加17%（OR = 1.17；95%置信区间 = 1.02, 1.34）和24%（OR = 1.24；95%置信区间 = 1.08, 1.43）。遥控器的 proximity（< 0.001）和电视机数量（= 0.03）与看电视时间呈正相关，机动车数量（95%置信区间 = 0.001, 0.12）与参与交通相关久坐时间的几率呈正相关。后两种关联受到BMI的调节，显著正相关仅限于非超重人群。总之，家庭环境因素与特定领域的久坐行为相关，尤其是在体重正常的成年人中。如果纵向研究证实这一点，公共卫生专业人员应鼓励成年人限制室内娱乐设备和机动车的数量。
