To determine the feasibility of a 3-month weight loss program for obese older women with short-term laboratory, performance, functional, and life quality outcomes.
This was a pre- and postintervention design. Community-dwelling women (n = 26) > or =60 years old with BMI > or =30 were enrolled in a 3-month weight loss program promoting prudent diet, behavior modification, and physical activity. The primary emphasis of the program was on health, function, and quality of life. The approach was specifically tailored to older subjects through use of large-font instructional materials, supplementation of calcium and vitamin D, and moderate weight loss and physical activity goals. An initial assessment by a bariatric physician was followed by eight visits with a dietitian and a follow-up physician visit. Measurements included anthropometrics, body composition, laboratories, pedometer, physical performance, Short-Form 36 Health Status Survey (SF-36), Life Space Assessment, and dietary assessment.
Eighteen participants completed the program. There was a significant decrease in mean body weight (100 +/- 15 vs. 96 +/- 18 kg, p = 0.006), with a mean weight loss of 4.3 +/- 5.5 kg (range -15.5 to +7.20 kg). Significant improvements were observed for diastolic blood pressure, total cholesterol, triglycerides, physical performance, pedometer-measured step counts, and step climb and descent. Self-rated physical functioning (SF-36 subscore) and vitality (SF-36 subscore) were also significantly improved.
It is feasible for self-selected obese older women to achieve a moderate weight loss and increase in physical activity resulting in short-term improvements in laboratory, physical performance, self-reported function, vitality, and life quality outcomes.
确定一项针对肥胖老年女性的为期3个月的体重减轻计划的可行性，并观察其短期实验室指标、身体机能、功能和生活质量方面的结果。
这是一项干预前后设计的研究。招募年龄≥60岁、体重指数（BMI）≥30的社区居住女性（n = 26）参加一项为期3个月的体重减轻计划，该计划促进合理饮食、行为改变和体育活动。该计划主要强调健康、功能和生活质量。通过使用大号字体的指导材料、补充钙和维生素D以及设定适度的体重减轻和体育活动目标，该方法专门针对老年受试者进行了调整。由减肥医生进行初步评估，随后与营养师进行8次就诊，并进行一次随访医生就诊。测量指标包括人体测量学、身体成分、实验室检查、计步器、身体机能、简短健康调查问卷（SF - 36）、生活空间评估和饮食评估。
18名参与者完成了该计划。平均体重显著下降（100±15 vs. 96±18 kg，p = 0.006），平均体重减轻4.3±5.5 kg（范围 - 15.5至 + 7.20 kg）。舒张压、总胆固醇、甘油三酯、身体机能、计步器测量的步数以及上下楼梯步数均有显著改善。自我评定的身体功能（SF - 36子评分）和活力（SF - 36子评分）也有显著改善。
自我选择的肥胖老年女性实现适度体重减轻并增加体育活动是可行的，这会在短期内改善实验室指标、身体机能、自我报告的功能、活力和生活质量结果。
