The prevalence of no leisure-time physical activity (LTPA) among US adults is estimated to be between 24% and 30%. Such information, however, usually does not include prevalence estimates for non-Hispanic blacks, Mexican Americans, and the elderly.
To assess the prevalence of participation in leisure-time physical activity among US adults.
Between 1988 and 1991, 9488 adults aged 20 years and older were interviewed in their home as part of the third National Health and Nutrition Examination Survey. A clinic examination in a mobile center was also included. Mexican Americans, non-Hispanic blacks, and the elderly were oversampled to produce reliable estimates for these groups. Questions were asked about the type and frequency of physically active hobbies, sports, and exercises.
The prevalence of no LTPA for US adults aged 20 years or older from 1988 through 1991 was 22%. The rate was higher in women (27%) than in men (17%). Mexican-American men (33%) and women (46%) and non-Hispanic black women (40%) had the highest rates of no LTPA. Participation in moderate to vigorous LTPA five or more times per week decreased with age, with the largest decreases observed among non-Hispanic black men and women. In almost all subpopulations, gardening and/or yard work and walking were stated as the two top LTPAs of choice.
Many Americans are inactive or irregularly active during their leisure time. Rates of inactivity are greater for women, older persons, non-Hispanic blacks, and Mexican Americans. Intervention strategies meant to promote lifetime physical activities among all Americans represents a major health priority.
据估计，美国成年人中无休闲时间体育活动（LTPA）的比例在24%至30%之间。然而，此类信息通常不包括非西班牙裔黑人、墨西哥裔美国人以及老年人的患病率估计。
评估美国成年人参与休闲时间体育活动的患病率。
1988年至1991年期间，作为第三次全国健康与营养检查调查的一部分，对9488名20岁及以上的成年人进行了家访。还包括在流动中心进行的临床检查。对墨西哥裔美国人、非西班牙裔黑人以及老年人进行了过度抽样，以便对这些群体得出可靠的估计。询问了有关体育活动爱好、运动和锻炼的类型及频率的问题。
1988年至1991年期间，20岁及以上美国成年人无LTPA的患病率为22%。女性（27%）的患病率高于男性（17%）。墨西哥裔美国男性（33%）和女性（46%）以及非西班牙裔黑人女性（40%）无LTPA的比例最高。每周进行五次或更多次中度至剧烈LTPA的比例随年龄增长而下降，在非西班牙裔黑人男性和女性中下降幅度最大。在几乎所有亚群体中，园艺和/或庭院工作以及散步被列为最常选择的两项LTPA。
许多美国人在休闲时间不活动或活动不规律。女性、老年人、非西班牙裔黑人以及墨西哥裔美国人的不活动率更高。旨在促进所有美国人终身体育活动的干预策略是一项重大的健康优先事项。
