体育活动可以改善健康，并可能延缓几种慢性疾病的发病。特别是对妇女来说，这些疾病的发病率在中年时加速；因此，确定中年人群中促进健康的体力活动的决定因素是很重要的。在这项研究中，我们关注的是女性独有的决定因素，如生育和更年期。研究的主要目的是确定芬兰中年妇女身体活动水平的特征，以及活跃和不活跃妇女之间的差异。此外，我们还研究了体力活动与女性中年生殖因素的关系。研究人群包括647名年龄在48至55岁之间的女性，她们在2015年至2016年期间参加了我们的雌激素调节肌肉凋亡（ERMA）研究。连续7天使用穿戴在臀部的加速度计客观地测量身体活动。结果测量包括在至少10分钟的回合中积累的轻度体力活动和中度至剧烈体力活动的量（MVPA(10)）。MVPA（10）用于确定女性是处于运动（>= 150分钟/周）还是不运动(
Physical activity improves health and may delay the onset of several chronic diseases. For women in particular, the rate of these diseases accelerates at middle age; therefore it is important to identify the determinants of health-enhancing physical activity during midlife in this population. In this study, we focused on determinants that are unique to the female sex, such as childbearing and menopause. The main objective was to characterize the level of physical activity and differences between active and inactive middle-aged Finnish women. In addition, we examined the association of physical activity with female reproductive factors at midlife. The study population consisted of 647 women aged 48 to 55 years who participated in our Estrogenic Regulation of Muscle Apoptosis (ERMA) study during the period from 2015 to 2016. Physical activity was measured objectively using hip-worn accelerometers for seven consecutive days. The outcome measures included the amounts of light intensity physical activity and moderate to vigorous intensity physical activity accumulated in bouts of at least 10 minutes (MVPA(10)). MVPA(10) was used to determine whether women were placed in the active (>= 150 min/week) or inactive (
