Perceived barriers are modifiable correlates of participation in physical activity. Associations of specific perceived barriers with participation in and level of walking for recreation, and other leisure-time physical activity (LTPA) were examined. Personal, social, and environmental factors associated with these perceived barriers were then examined.
From 2003 to 2004, 2 surveys collected data on recreational walking and other LTPA, perceived barriers to participation, and personal, social, and environmental attributes, from 2194 Australian adults. Zero-inflated negative binomial regression models examined associations of perceived barriers with walking and other LTPA. Generalized linear models identified the correlates of these perceived barriers.
The perceived barriers of lack of motivation and time were associated with level of LTPA, while lack of motivation, poor health, and lack of facilities were associated with the odds of nonparticipation in LTPA. Personal, social, and environmental factors independently contributed to variations in perceived barriers.
Level and likelihood of participation in LTPA are associated with different perceived barriers. Perceived barriers are a function of both nonmodifiable personal factors and potentially modifiable personal, social, and environmental factors. These findings suggest that the provision of relevant environmental opportunities and social support may effectively reduce perceived barriers to LTPA.
感知障碍是身体活动参与的可改变相关因素。本研究旨在检验特定感知障碍与娱乐性散步和其他闲暇时间身体活动（LTPA）的参与和水平之间的关系，并进一步探讨与这些感知障碍相关的个人、社会和环境因素。
2003 年至 2004 年，对来自 2194 名澳大利亚成年人的休闲散步和其他 LTPA、参与障碍感知以及个人、社会和环境属性数据进行了 2 次调查。零膨胀负二项回归模型检验了感知障碍与散步和其他 LTPA 的关系。广义线性模型确定了这些感知障碍的相关性。
缺乏动机和时间的感知障碍与 LTPA 的水平相关，而缺乏动机、健康状况不佳和缺乏设施与不参与 LTPA 的几率相关。个人、社会和环境因素独立影响感知障碍的差异。
LTPA 的参与水平和可能性与不同的感知障碍相关。感知障碍是不可改变的个人因素和潜在可改变的个人、社会和环境因素的综合作用。这些发现表明，提供相关的环境机会和社会支持可能有效地减少 LTPA 的感知障碍。
