Abstract

OBJECTIVE

To investigate the effects of a specific program to implement physical activity (fitness program) on weight loss maintenance, activity level and resting energy expenditure (REE).

DESIGN

Observational study of subjects completing a behavioral program.

SUBJECTS

In total, 200 overweight/obese subjects (36 males, aged 20-66 years; average BMI, 35.2 kg/m2). Program and measurements:The fitness program consisted of 12 bimonthly sessions, chaired by doctors and dietitians, involving groups of 8-12 subjects. Patients entered the program approximately 9 months after the end of behavioral treatment, during a weight loss maintenance period. The goal was set at a light-to-moderate daily physical activity (brisk walking), quantitatively measured by a pedometer; REE was measured before and after the fitness program by indirect calorimetry in a subset of patients.

RESULTS

The fitness program restarted the process of weight loss in over 60% of subjects. At the end of the study, 84% of patients walked at least 5000 steps per day, compared with 24% at the beginning of the study. The probability of losing from 5 to 10% of initial body weight increased by 20% for any 1000 steps/day (OR, 1.20; 95% CI (confidence interval), 1.07-1.35), and that of losing more than 10% by over 30% (OR, 1.33; 95% CI, 1.19-1.49). REE increased significantly by 100 kcal/day (+7.5%), in spite of further weight loss (-1.8%).

CONCLUSION

A specific fitness program in the weight maintenance phase after a behavioral program may significantly improve the long-term control of obesity.

摘要

目的

研究一项实施体育活动的特定计划（健身计划）对体重维持、活动水平和静息能量消耗（REE）的影响。

设计

对完成一项行为计划的受试者进行观察性研究。

受试者

总共200名超重/肥胖受试者（36名男性，年龄20 - 66岁；平均BMI为35.2kg/m²）。计划与测量：健身计划包括由医生和营养师主持的12次双月课程，每组8 - 12名受试者。患者在行为治疗结束后约9个月进入该计划，处于体重维持期。目标设定为轻度至中度的日常体育活动（快走），通过计步器进行定量测量；在一部分患者中，通过间接测热法在健身计划前后测量REE。

结果

健身计划使超过60%的受试者重新开始体重减轻过程。在研究结束时，84%的患者每天至少走5000步，而研究开始时这一比例为24%。每天每多走1000步，体重减轻初始体重的5%至10%的概率增加20%（比值比[OR]，1.20；95%置信区间[CI]，1.07 - 1.35），体重减轻超过10%的概率增加超过30%（OR，1.33；95%CI，1.19 - 1.49）。尽管体重进一步减轻（-1.8%），REE仍显著增加100千卡/天（+7.5%）。
