| Vasconcelos et al.(13)
|
To examine the influence of pain intensity, radiographic severity, obesity level and symptom duration on the functional capacity of obese individuals with knee OA |
Cross-sectional |
Pain intensity is a factor that influences functional activity performance among obese individuals with knee OA. In addition, clinically and radiographically, sample had moderate affection of knee OA |
| Vasconcelos et al.(14)
|
To compare the impact of the degree of obesity in symptoms and functional capacity of women with knee OA |
Case-control |
The degree of obesity had no impact on knee OA symptoms of pain, stiffness and functional difficulty in both obese women and women with morbid obesity |
| Chacur et al.(15)
|
To assess the correlations between body mass index, Waist circumference and Waist/Hip Circumference Ratio with Knee OA and observed association of these anthropometrical variables with severity of knee OA |
Cross-sectional |
Severity of OA was positive correlated with BMI and waist circumpherence |
| Rosis et al.(16)
|
To evaluate most and least affected joints, age patterns, sex, comorbidities and BMI, as well as its associations with appearance and development of OA in elderlies living long-term care institution |
Cross-sectional |
The high occurrence of OA in the population was related with advanced age, excessive weight and comorbidities that worsen the disease |
| Aurichio et al.(17)
|
To determine prevalence of obesity and its association in old population living in the city of São Carlos (SP, Brazil) |
Cross-sectional |
An association was found between the obese and presence of diabetes. In addition, women were more obese, reported joint pain and excessive body weight |
| Chacur et al.(18)
|
To determine possible correlations between anthropometric features, Q angle and knee OA in obese women |
Cross-sectional |
Abdominal obese, its degree and duration possibly contribute to incidence of knee OA in obese women |
| Christensen et al.(19)
|
To assess changes in micronutrient status (vitamin D, ferritin, and vitamin B12) and body composition in obese individuals after a dietary weight loss program |
Prospective cohort |
Weight loss can be successfully achieve in OA patients, especially if the diet includes enough nutrientes, therefore increasing bone mineral density and levels of vitamin D ande B12 |
| Elbaz et al.(20)
|
To examine the associations of sex, body mass index, and age with knee OA symptomatic severity |
Cross-sectional |
Higher BMI correlated significantly with worse in knee OA symptoms |
| Qin et al.(21)
|
To examine the cross-sectional association between dietary magnesium intake and the radiographic knee OA among African-American and Caucasian men and women |
Cross-sectional |
Magnesium intake in the diet was inversely proportional to presence of knee OA in Caucasians but not in African Americans |
| Fahlman et al.(22)
|
To observe old individuals without OA at age 78, describing their height, weight and body mass index |
Cross-sectional |
Higher BMI is recognized as a risk factor for knee OA. Elderlies aged 78 years who were overweight did not have knee OA. A possible explanation may be an “inflated” BMI based on decrease in height, not just increase in weight |
| Holla et al.(23)
|
To assess whether BMI and depressed mood are independently associated with knee pain and activity limitations; and to compare the relative contributions of BMI and depressed mood to knee pain and activity limitations |
Cross-sectional |
In patients with knee OA, the BMI and depressed mood were positively and independently associated with knee pain and activity limitations |
| Lee et al.(24)
|
To examine the risk factors for OA and the contributing factors to current arthritic pain in older adults |
Cross-sectional |
Age, female gender, higher body mass index, and osteoporosis were significant risk factors for OA, while higher education level was a protective factor for OA |
| Weiss(25)
|
To determine whether BMI increases knee pain in individuals without severe knee OA |
Cross-sectional |
Weight loss may reduce knee OA pain even if the osteological symptoms are not treated |
| Ho-Phan et al.(26)
|
To investigate whether the association between BMI and OA is mediated by fat mass or lean mass |
Cross-sectional |
The association between body mass index and OA is mainly mediated by fat mass |
| Reyes et al.(27)
|
To analyze the effect of being overweight or obese on the incidence of routinely diagnosed knee, hip, and hand OA |
Prospective cohort |
Being overweight or obese increases the risk of hand, hip, and knee OA, with the greatest risk in the knee, and this occurs on response of increasing BMI |
