To determine the prevalence of achieving new recommended levels of physical activity, the types of activity involved, and their determinants among elderly British women.
National cross sectional survey.
2341 women aged 60 to 79 from 15 British towns.
Prevalence of subjects achieving recommended levels of physical activity.
Over two thirds of the participants were active at new recommended levels. This was mainly achieved through participation in heavy housework. If domestic activities were excluded only 21% were regularly active. Women who participated in brisk walking for at least 2.5 hours per week had reduced odds of being overweight: odds ratio (95% confidence intervals) 0.5 (0.3 to 0.6) after adjustment for other forms of activity, health status, smoking, and socioeconomic position. Participating in at least 2.5 hours of heavy housework was not associated with reduced odds of being overweight 1.1 (0.8 to 1.4). Age, self reported poor health status, coronary heart disease, and respiratory disease were independently associated with reduced odds of participating in all types of activity. In addition participation in brisk walking and physical exercise were less likely in current smokers, those from the lowest socioeconomic class, and those living in the north of the country. Participation in heavy housework was less likely in women reporting depression but was not associated with smoking, socioeconomic class, or area of residence.
If new physical activity recommendations, which include domestic activities, are used to assess population levels of physical activity then it seems that the majority of elderly women are sufficiently active. Heavy housework is not associated with reduced levels of being overweight and prospective studies are necessary to demonstrate an independent health benefit of participating in domestic activities.
确定达到新推荐身体活动水平的老年英国女性的患病率、所涉及的活动类型及其决定因素。
全国横断面调查。
来自英国15个城镇的2341名60至79岁的女性。
达到推荐身体活动水平的受试者患病率。
超过三分之二的参与者达到了新的推荐活动水平。这主要是通过参与繁重的家务劳动实现的。如果排除家务活动，只有21%的人经常进行身体活动。每周至少快走2.5小时的女性超重几率降低：在对其他形式的活动、健康状况、吸烟和社会经济地位进行调整后，优势比（95%置信区间）为0.5（0.3至0.6）。参与至少2.5小时的繁重家务劳动与超重几率降低无关，优势比为1.1（0.8至1.4）。年龄、自我报告的健康状况差、冠心病和呼吸系统疾病与参与所有类型活动的几率降低独立相关。此外，当前吸烟者、社会经济阶层最低的人群以及居住在该国北部的人群参与快走和体育锻炼的可能性较小。报告有抑郁症的女性参与繁重家务劳动的可能性较小，但与吸烟、社会经济阶层或居住地区无关。
如果使用包括家务活动在内的新身体活动建议来评估人群的身体活动水平，那么似乎大多数老年女性的身体活动量足够。繁重的家务劳动与超重水平降低无关，需要进行前瞻性研究来证明参与家务活动对健康的独立益处。
