Lipedema prevalence and risk factors in Brazil

BACKGROUND: Lipedema is characterized as an abnormal deposition of fat in the buttocks and legs bilaterally that may be accompanied by swelling, pain, and tenderness. It is still often confused with more frequent conditions such as obesity and lymphedema. The estimated prevalence in Europe varies between 0.06% and 39%. OBJECTIVES: To evaluate the prevalence of lipedema and identify health factors related to it in the Brazilian population. METHODS: Administration of a previously validated online screening questionnaire to a representative sample of the general population. The questionnaire was distributed and administered to anonymous volunteers representing the general Brazilian population using software designed for population analyses. RESULTS: 253 women answered the questionnaire, 12.3 ± 4% (Confidence Interval [CI] 95%) of whom presented symptoms compatible with a high probability of being diagnosed with lipedema. Furthermore, anxiety, depression, hypertension, and anemia were also correlated with a high probability of the diagnosis. CONCLUSIONS: The estimated prevalence of lipedema in the population of Brazilian women is 12.3%.
