BACKGROUND: Lipedema is a prevalent chronic condition in women, characterized by a painful and symmetrical accumulation of adipose tissue primarily in the lower limbs. Its diagnosis is based on specific clinical characteristics; however, these characteristics lack robust scientific validation. Furthermore, lipedema is frequently misdiagnosed as obesity. This study aims to compare quality of life and physical and psychological characteristics between patients with obesity with and without lipedema. METHODS: This cross-sectional study included 30 patients with obesity and lipedema (Lip-Obes group) and 29 patients with only obesity (nonLip-Obes group). Quality of life, body composition (BMI, fat free mass, fat mass, waist-to-hip ratio, waist-to-height ratio, leg volume), pain (pain pattern, pressure pain thresholds, pain interference, pain distribution, symptoms of neuropathic pain), physical functioning (hand grip strength, quadriceps strength, functional exercise capacity, functional mobility and physical activity level), and psychosocial functioning (pain catastrophizing, depression, anxiety, and stress, body image dissatisfaction, self-efficacy, and eating difficulties) were assessed using clinical measurements and self-reported outcomes. Statistical analyses were performed using independent t-tests or Mann-Whitney U tests for continuous variables and Chi-square or Fisher's exact tests for categorical variables. A two-sided p-value of < 0.05 was considered statistically significant. RESULTS: Compared to the nonLip-Obes group, the Lip-Obes group showed greater impairments in quality of life (p < 0.05). Despite similar body composition variables, the Lip-Obes group had lower waist-to-hip, waist-to-height, upper leg-to-waist, and lower leg-to-waist ratios, as well as higher total limb volume than the nonLip-Obes group. Additionally, the Lip-Obes group reported higher pain intensity, lower pressure pain thresholds in the arms and legs, and greater pain interference than the nonLip-Obes group (p < 0.05). Although hand-grip strength and physical activity levels were comparable, the Lip-Obes group exhibited lower quadriceps strength, functional exercise capacity, and functional mobility (p < 0.05). Additionally, the Lip-Obes group reported higher pain catastrophizing, greater body image dissatisfaction, and more severe eating difficulties than the nonLip-Obes group (p < 0.05). No significant differences were found in depression, anxiety, stress, or self-efficacy between groups (p > 0.05). CONCLUSION: This cross-sectional study highlights the complex nature of lipedema, providing preliminary evidence of differences in quality of life and distinct body composition and physical and physiological characteristics between patients with obesity with and without lipedema. These results emphasize the need for further research to identify diagnostic biomarkers for lipedema through in-depth investigations. Future studies should also focus on developing and optimizing a multidisciplinary treatment approach tailored to the unique characteristics of patients with lipedema.

Purpose: Upper limb lymphedema is a vexing morbidity that can occur after the treatment for breast cancer. The Lymphedema Functioning, Disability and Health Questionnaire for Upper Limb Lymphedema (Lymph-ICF-UL) is a valid and reliable tool assessing problems in functioning in patients with breast cancer-related lymphedema. Until now, a French-language version was lacking. The aim of this study was to perform a cross-cultural validation of the French version of the Lymph-ICF-UL questionnaire.Methods: A forward-backward translation process between the original language (Dutch) and the target language (French) was performed. Psychometric properties of this final French version were examined in 50 participants.Results: Intraclass correlation coefficients for test-retest reliability ranged from 0.66 to 0.95. Cronbach's alpha coefficients for internal consistency were higher than 0.77. Face and content validity were very good because the scoring system was clear for all participants (100%), questions were understandable (100%), and all complaints due to BCRL were mentioned by 78% of the participants. Construct validity was moderate. Convergent validity was established since 3 out of 5 expected domains of the Lymph-ICF-UL showed a moderate correlation with expected domains of the 36-item Short-Form Health Survey. There was satisfactory divergent validity as 6 out of 9 hypotheses assessing divergent validity were accepted.Conclusion: The French version of the Lymph-ICF-UL is a reliable and valid questionnaire and ready for use in clinical as well as in scientific practice.Implications for rehabilitationSince the introduction of more effective treatment modalities increasing the number of breast cancer survivors, the amount of patients dealing with lymphedema is rising likewise up to a pooled incidence rate of more than 16% of the women treated for breast cancer.The French version of the Lymph-ICF-UL is a reliable and valid questionnaire for assessing problems in functioning of patients with breast cancer-related lymphedema of the arm and/or hand.As the questionnaire provides patient information in the different domains of the International Classification of Functioning, Disability and Health, it facilitates evaluating the impact of breast cancer-related lymphedema on daily functioning.Based on the outcomes of the Lymph-ICF-UL treatment goals can be set, where after the questionnaire can be used to monitor long-term results of this treatment and self-care.
