High intake of fruit and vegetables and being physically active are associated with reduced risk of chronic diseases. In the current study, we examined the associations of physical activity, fruit and vegetable consumption, and TV/video watching (indicator for physical inactivity) with perceived quality of life (QOL) in a sample of free living adults.
A cohort (N = 139) from a random, multi-ethnic sample of 700 adults living in Hawaii was evaluated at 3-month intervals for the first year and 6-month intervals for the second year. QOL was assessed from self-reports of mental or physical health at the end of the study.
Overall, the cohort participants appeared to maintain relatively constant levels of physical activity, fruit and vegetable intake, and TV/video watching. Physical activity was positively related to mental health (p-values < 0.05), but not physical health, at all time points regardless of participants' fruit and vegetable consumption and hours of TV/video watching. Neither mental nor physical health was associated with fruit and vegetable intake or TV/video watching.
Our study supports that physical activity is positively associated with mental health. Fruit and vegetable consumption and TV/video watching may be too specific to represent an individual's overall nutritional status and physical inactivity, respectively.
摄入大量水果和蔬菜并积极参加体育锻炼与降低慢性病风险有关。在本研究中，我们在一个由自由生活的成年人组成的样本中，研究了体育活动、水果和蔬菜摄入以及看电视/视频（久坐不动的指标）与感知生活质量（QOL）之间的关联。
在夏威夷，对一个由 700 名成年人组成的随机多民族样本中的队列（N=139）进行了为期一年的每三个月一次和第二年每六个月一次的评估。在研究结束时，通过自我报告心理健康或身体健康来评估 QOL。
总体而言，队列参与者的体育活动、水果和蔬菜摄入量以及看电视/视频的时间似乎保持相对稳定的水平。无论参与者的水果和蔬菜摄入量以及看电视/视频的时间如何，体育活动与心理健康在所有时间点均呈正相关（p 值均<0.05），但与身体健康无关。心理健康或身体健康均与水果和蔬菜摄入或看电视/视频观看无关。
我们的研究支持体育活动与心理健康呈正相关。水果和蔬菜的摄入和看电视/视频可能过于具体，无法代表个人的整体营养状况和身体活动不足。
