Sedentary behaviors, particularly television viewing (TV) time, are associated with adverse health outcomes in adults, independent of physical activity levels. These associations are stronger and more consistent for women than for men.
Multivariate regression models examined the sociodemographic correlates of 2 categories of TV time (≥ 2 hours/day and ≥ 4 hours/day); in a large, population-based sample of Australian adults (4950 men, 6001 women; mean age 48.1 years, range 25-91) who participated in the 1999/2000 Australian Diabetes, Obesity, and Lifestyle (AusDiab) study.
Some 46% of men and 40% of women watched ≥ 2 hours TV/day; 9% and 6% respectively watched ≥ 4 hours/day. For both men and women, ≥ 2 hours TV/day was associated with less than tertiary education, living outside of state capital cities, and having no paid employment. For women, mid and older age (45-64 and 65+) were also significant correlates of ≥ 2 hours TV/day. Similar patterns of association were observed in those viewing ≥ 4 hours/day.
Prolonged TV time is associated with indices of social disadvantage and older age. These findings can inform the understanding of potential contextual influences and guide preventive initiatives.
久坐行为，尤其是看电视（TV）时间，与成年人的健康结果不良有关，而与身体活动水平无关。这些关联在女性中比男性更强且更一致。
多变量回归模型研究了澳大利亚成年人（4950 名男性，6001 名女性；平均年龄 48.1 岁，范围 25-91 岁）中 2 类电视时间（≥2 小时/天和≥4 小时/天）的社会人口统计学相关性，他们参加了 1999/2000 年的澳大利亚糖尿病、肥胖和生活方式（AusDiab）研究。
分别有 46%的男性和 40%的女性每天观看≥2 小时的电视；分别有 9%和 6%的人每天观看≥4 小时的电视。对于男性和女性来说，每天观看≥2 小时的电视与未接受过高等教育、居住在州首府以外的地区以及没有带薪工作有关。对于女性来说，中年和老年（45-64 岁和 65 岁以上）也是每天观看≥2 小时电视的显著相关因素。每天观看≥4 小时电视的人也存在类似的关联模式。
长时间看电视与社会劣势和年龄较大有关。这些发现可以帮助理解潜在的环境影响，并指导预防措施。
