LOPEZ-GOMEZ, Juan-José et al. Influence of a meal-replacement diet on quality of life in women with obesity and knee osteoarthritis before orthopedic surgery. []. , 35, 1, pp.71-77. ISSN 1699-5198. https://dx.doi.org/10.20960/nh.1148.
Background:
Knee osteoarthritis is a disease with a high prevalence in our environment, especially in women. Weight loss can improve the quality of life of these patients before surgery.
Objectives:
To evaluate the effect of a meal-replacement diet on weight loss, body composition, and the improvement of the quality of life in obese women with knee osteoarthritis pending surgery.
Methods:
One branch intervention study was performed over three months on 81 women with a body mass index greater than 30 kg/m2 with knee osteoarthritis before surgery. Patients received a hyperproteic meal-replacement diet with two bottles of an oral nutrition supplement in lunch and dinner (1,035 kcal). Anthropometric parameters, and body composition were measured. The quality of life was assessed by WOMAC and SF-36 test.
Results:
The mean age of the patients was 62.23 (8.50) years. The percentage of weight loss was 8.23% (4.04). An improvement in the SF-36 total score was observed (basal: 49.35 [20.41], three months: 58.71 [17.07], p < 0.01). There was an improvement in WOMAC test (basal: 49.24% [25.53], three months: 40.59% [21.76], p < 0.01). It was observed that a 10% improvement in the SF-36 test was independently related to weight loss (OR: 1.2 [1.03-1.36], p < 0.02) adjusted by age and changes in body composition.
Conclusions:
In women with osteoarthritis of the knee treated with a meal-replacement diet, there is a significant decrease in weight and fat mass with a relative increase of the latter. There is an improvement in the quality of life according to SF-36 and WOMAC. There is an independent relationship between weight loss and SF-36 improvement.
