Comparing lifestyle of people remaining sedentary during longer periods of their life with those favourably changing their behaviour can provide cues to optimize interventions targeting sedentary behaviour. The objective of this study was to determine lifestyle predictors of sustained leisure time sedentary behaviour and assess whether these predictors were dependent on gender, age, socioeconomic position and occupational sedentary behaviour. Data from a large longitudinal population-based cohort of adults (aged 18-97years) in Stockholm responding to public health surveys in 2010 and 2014 were analysed (n=49,133). Leisure time sedentary behaviour was defined as >3h per day of leisure sitting time e.g. watching TV, reading or using tablet. Individuals classified as sedentary at baseline (n=9562) were subsequently categorized as remaining sedentary (n=6357) or reduced sedentary behaviour (n=3205) at follow-up. Lifestyle predictors were unfavourable alcohol consumption, smoking, nutrition, and physical activity. Odds ratios (OR) and corresponding 95% Confidence Intervals (CI) were calculated, adjusting for potential confounders. Unfavourable alcohol consumption (OR=1.22, CI:1.11-1.34), unfavourable candy- or cake consumption (OR=1.15, CI:1.05-1.25), and unfavourable physical activity in different contexts were found to predict sustained sedentary behaviour, with negligible differences according to gender, age, socioeconomic position and occupational sedentary behaviour. People with unfavourable lifestyle profiles regarding alcohol, sweets, or physical activity are more likely to remain sedentary compared to sedentary persons with healthier lifestyle. The impact of combining interventions to reduce leisure time sedentary behaviour with reducing alcohol drinking, sweet consumption and increasing physical activity should be tested as a promising strategy for behavioural modification.
比较生活方式久坐的人在他们的生活与那些有利改变他们的行为可以提供线索来优化干预措施针对久坐行为。本研究的目的是确定生活方式久坐行为的预测因子，并评估这些预测因子是否依赖于性别、年龄、社会经济地位和职业久坐行为。从斯德哥尔摩的一个大型纵向基于人群的成年人队列（年龄 18-97 岁）中分析了对 2010 年和 2014 年公共卫生调查的反应数据（n=49133）。休闲时间久坐行为定义为每天>3 小时的休闲坐姿时间，例如看电视、阅读或使用平板电脑。在基线时被归类为久坐的个体（n=9562）随后在随访时被归类为持续久坐（n=6357）或减少久坐行为（n=3205）。生活方式预测因素是不良的饮酒、吸烟、营养和体力活动。计算了优势比（OR）和相应的 95%置信区间（CI），并调整了潜在的混杂因素。不良的饮酒（OR=1.22，CI：1.11-1.34）、不良的糖果或蛋糕消费（OR=1.15，CI：1.05-1.25）以及不同环境下的不良体力活动被发现可预测持续久坐行为，性别、年龄、社会经济地位和职业久坐行为的差异可忽略不计。与生活方式更健康的久坐者相比，在饮酒、甜食或体力活动方面生活方式不佳的人更有可能保持久坐不动。应该测试减少休闲时间久坐行为与减少饮酒、减少甜食摄入和增加体力活动相结合的干预措施的影响，作为行为改变的一种有前途的策略。
