All comprehensive US cancer control plans mention physical activity and implement physical activity promotion objectives as part of these cancer plans. The purpose of this investigation was to describe the physical activities reported by Alabama adults in the 2013 Behavioral Risk Factor Surveillance System (BFRSS) and to compare these activities by age group and relative exercise intensity.
This investigation used data on 6503 respondents from the 2013 BRFSS sample of respondents from Alabama with landline and cellular telephones. Respondents were asked whether they engaged in any physical activities or aerobic exercises such as running, calisthenics, golf, gardening, or walking. Information was collected on strengthening activities such as yoga, sit-ups, push-ups, and using weight machines, free weights, and elastic bands. Relative exercise intensity was estimated for each aerobic activity by comparing the 60% maximal oxygen uptake with metabolic equivalent values.
Approximately two-thirds (63.7%) of respondents reported that they engaged in exercise in the past 30 days; 45.4% participated in enough aerobic activity per week to meet guidelines, and 25.9% met the muscle-strengthening guidelines. Only 10.1% of respondents 65 years old and older met both aerobic and muscle-strengthening guidelines, compared with 15.2% of those 18 to 64 years old (P < 0.05). The most common activity reported for ages 18 to 64 years was walking (53.3%), followed by running (12.7%), and gardening (4.7%). Among adults aged 65 and older, the top three activities were walking (63.2%), gardening (13.3%), and use of a bicycle machine (2.9%). The activity intensity was significantly greater for walking, gardening, and household activities among older adults compared with those younger than age 65.
Because the recommended levels of physical activity are not met by a majority of Alabama residents, it is important to incorporate this information into state cancer objectives. Older adults may have higher relative energy costs compared with younger adults. Future studies should discern whether activities previously classified as low intensity have adequate health benefits, especially for cancer survivors and older adults with comorbidities.
美国所有的癌症综合防控计划均提及身体活动,并将促进身体活动目标作为这些癌症计划的一部分予以实施。本调查旨在描述阿拉巴马州成年人在2013年行为危险因素监测系统(BFRSS)中报告的身体活动情况,并按年龄组和相对运动强度对这些活动进行比较。
本调查使用了2013年阿拉巴马州BFRSS样本中6503名通过固定电话和手机参与调查的受访者的数据。受访者被问及是否进行任何身体活动或有氧运动,如跑步、健身操、高尔夫、园艺或散步。收集了有关强化活动的信息,如瑜伽、仰卧起坐、俯卧撑以及使用健身器械、自由重量器械和弹力带等。通过将60%的最大摄氧量与代谢当量值进行比较,估算每项有氧运动的相对运动强度。
约三分之二(63.7%)的受访者报告称在过去30天内进行过锻炼;45.4%的人每周参与足够的有氧运动以达到指南要求,25.9%的人达到了肌肉强化指南要求。65岁及以上的受访者中只有10.1%同时达到了有氧运动和肌肉强化指南要求,而18至64岁的受访者中这一比例为15.2%(P<0.05)。18至64岁人群报告的最常见活动是散步(53.3%),其次是跑步(12.7%)和园艺(4.7%)。在65岁及以上的成年人中,排名前三的活动是散步(63.2%)、园艺(13.3%)和使用自行车健身器(2.9%)。与65岁以下的人群相比,老年人在散步、园艺和家务活动中的活动强度明显更大。
由于阿拉巴马州的大多数居民未达到推荐的身体活动水平,因此将此信息纳入该州癌症目标非常重要。与年轻人相比,老年人可能有更高的相对能量消耗。未来的研究应确定以前被归类为低强度的活动是否具有足够的健康益处,特别是对癌症幸存者和患有合并症的老年人。
