BACKGROUND
It has been pointed out that prolonged television (TV) viewing is one of the sedentary behaviors that is harmful to health; however, the association between socioeconomic status (SES) and prolonged TV viewing time has not been sufficiently investigated in Japan.
METHODS
The study population are the participants of NIPPON DATA2010, which is a prospective cohort study of the National Health and Nutrition Survey 2010 in Japan. They were residents in 300 randomly selected areas across Japan. This study included 2752 adults. SES was classified according to the employment status, educational attainment, living status, and equivalent household expenditure (EHE). Prolonged TV viewing time was defined as more than or equal to 4 h of TV viewing per day. Multivariable logistic regression analyses were conducted to examine the association of SES with prolonged TV viewing time.
RESULTS
The mean TV viewing time was 2.92 h in all participants. Of 2752 participants, 809 (29.4%) prolonged TV viewing, and the mean TV viewing time of them was 5.61 h. The mean TV viewing time in participants without prolonged TV viewing time was 1.81 h. The mean TV viewing time was prolonged as age classes increased and significantly longer in aged ≥60 years. Prolonged TV viewing time was associated with not working for all age classes and sexes. Only among women, education attainment and living status were also associated with prolonged TV viewing time. For education attainment, the lower the received years of education, the higher odds ratios (OR) of prolonged TV viewing time. For living status, in women aged <60 years, living with others had a significantly higher OR compared to living with spouse. On the other hand, in women aged ≥60 years, living alone had a significantly higher OR. EHE did not have any significant associations with prolonged TV viewing time.
CONCLUSIONS
In a general Japanese population, it should be noted that the association between SES and prolonged TV viewing time differed by age and sex. Particularly, it must draw attention to the prolonged TV viewing in elderly. The intervention in order to shorten TV viewing time needs to consider these attributes.
背景
长时间看电视（TV）被认为是对健康有害的久坐行为之一；然而，在日本，社会经济地位（SES）与长时间看电视之间的关系尚未得到充分研究。
方法
本研究的研究对象是日本 2010 年全国健康和营养调查的前瞻性队列研究 NIPPON DATA2010 的参与者。他们是日本 300 个随机选定地区的居民。本研究共纳入 2752 名成年人。SES 根据就业状况、受教育程度、居住状况和家庭等效支出（EHE）进行分类。长时间看电视被定义为每天看电视超过或等于 4 小时。采用多变量逻辑回归分析SES 与长时间看电视之间的关系。
结果
所有参与者的平均电视观看时间为 2.92 小时。在 2752 名参与者中，有 809 人（29.4%）长时间看电视，他们的平均电视观看时间为 5.61 小时。没有长时间看电视的参与者的平均电视观看时间为 1.81 小时。随着年龄组的增加，平均电视观看时间延长，年龄≥60 岁的参与者的电视观看时间显著延长。所有年龄组和性别的人不工作都与长时间看电视有关。只有女性的受教育程度和居住状况也与长时间看电视有关。对于受教育程度，受教育年限越低，长时间看电视的几率比（OR）越高。对于居住状况，在年龄<60 岁的女性中，与配偶同住的人比与其他人同住的人 OR 更高。另一方面，在年龄≥60 岁的女性中，独居的人 OR 更高。EHE 与长时间看电视之间没有任何显著关联。
结论
在日本普通人群中，应注意 SES 与长时间看电视之间的关系因年龄和性别而异。特别是，必须注意老年人长时间看电视的问题。为了缩短看电视的时间，需要考虑这些因素。
