支持预防长期体重增加的体育活动指南的数据很少,特别是在体重增加风险最高的时​​期。评估20年来习惯性活动水平与体重指数(BMI)和腰围变化之间的关系。年轻人冠状动脉风险发展 (CARDIA) 研究是一项前瞻性纵向研究,从 1985 年 86 月到 2005 年 6 月进行了 20 年的随访。习惯性活动被定义为根据基线时特定性别的活动得分三分位数维持高、中和低的活动水平。参与者包括基于人口的多中心队列(伊利诺伊州芝加哥、阿拉巴马州伯明翰、明尼苏达州明尼阿波利斯和加利福尼亚州奥克兰),由 3554 名基线年龄为 18 至 30 岁的男性和女性组成。 BMI 和腰围的平均每年变化 20 多年来,在对种族、基线 BMI、年龄、教育程度、吸烟状况、饮酒和能量摄入进行调整后,与低活动水平相比,保持高活动水平与 BMI 和腰围的增加较小相关。保持高活动量的男性体重增加了 2.6 公斤(每年 + 0.15 BMI 单位;95 % 置信区间 [CI] 0.11-0.18 对比低活动量组的 +0.20;95% CI,0.17-0.23),保持较高活动量的女性体重增加了 6.1 公斤(每年 + 0.17 BMI 单位;95 % CI,0.12-0.21)相对于较低活动组的 +0.30;95% CI,0.25-0.34)。保持高活动量的男性腰围减少了 3.1 厘米(每年增加 0.52 厘米;95% CI,0.43-0.61 厘米,而低活动量组的腰围增加了 0.67 厘米;95% CI,0.60-0.75),而保持较高活动量的女性腰围减少了 3.8 厘米(每年增加 0.49 厘米;95% CI,低活动组为 0.39-0.58 vs 0.67 cm;95% CI,0.60-0.75)。当年轻人过渡到中年时,在成年早期保持高活动水平可能会减少体重增加,尤其是女性。
Data supporting physical activity guidelines to prevent long-term weight gain are sparse, particularly during the period when the highest risk of weight gain occurs. To evaluate the relationship between habitual activity levels and changes in body mass index (BMI) and waist circumference over 20 years. The Coronary Artery Risk Development in Young Adults (CARDIA) study is a prospective longitudinal study with 20 years of follow-up, 1985-86 to 2005-06. Habitual activity was defined as maintaining high, moderate, and low activity levels based on sex-specific tertiles of activity scores at baseline. Participants comprised a population-based multi-center cohort (Chicago, Illinois; Birmingham, Alabama; Minneapolis, Minnesota; and Oakland, California) of 3554 men and women aged 18 to 30 years at baseline. Average annual changes in BMI and waist circumference Over 20 years, maintaining high levels of activity was associated with smaller gains in BMI and waist circumference compared with low activity levels after adjustment for race, baseline BMI, age, education, cigarette smoking status, alcohol use, and energy intake. Men maintaining high activity gained 2.6 fewer kilograms (+ 0.15 BMI units per year; 95 % confidence interval [CI] 0.11-0.18 vs +0.20 in the lower activity group; 95% CI, 0.17-0.23) and women maintaining higher activity gained 6.1 fewer kilograms (+0.17 BMI units per year; 95 % CI, 0.12-0.21 vs. +0.30 in the lower activity group; 95 % CI, 0.25-0.34). Men maintaining high activity gained 3.1 fewer centimeters in waist circumference (+0.52 cm per year; 95 % CI, 0.43-0.61 cm vs 0.67 cm in the lower activity group; 95 % CI, 0.60-0.75) and women maintaining higher activity gained 3.8 fewer centimeters (+0.49 cm per year; 95 % CI, 0.39-0.58 vs 0.67 cm in the lower activity group; 95 % CI, 0.60-0.75). Maintaining high activity levels through young adulthood may lessen weight gain as young adults transition to middle age, particularly in women.
