Among the risk factors are: Advanced age, genetic factors and nutritional deficiencies, 25% of people with osteoporosis refer to postmenopausal women, with a prevalence of lumbar osteoporosis between 15.8% to 54.5%. The Assessment of Health related Quality of Life in Osteoporosis (ECOS-16) questionnaire is a tool aimed at measuring the quality of life of women with postmenopausal osteoporosis. The questionnaire contains 16 items present in four subscales. Objective: To translate, adapt to Brazilian culture and test the validity of the Assessment of Health related Quality of Life in Osteoporosis (ECOS-16) questionnaire. Methods: This is a cross-sectional study carried out in two stages: Translate into Portuguese and carry out the cross-cultural adaptation of the ECOS16; and to test the validity of the construct for the Brazilian population. Fifty-six women diagnosed with postmenopausal lumbar osteoporosis participated in the study.

Results: Of the 63 women who responded to the questionnaire, 5 did not meet the inclusion criteria and 2 did not complete the questionnaire in full. ); married (42%), with complete postgraduate studies (42%); white race (64%); with an income of 3 to 6 minimum wages (33%) and with a time of diagnosis of the disease of 54 months. The internal consistency of ECOS 16 analyzed using Cronbach's alpha (0.94) indicated good internal consistency, the correlation of each item with its subscale showed substantial correlations. The analysis showed significant correlations between all subscales of ECOS 16 and SF-36 (p-value <0.64) and END (p-value 0.69). Conclusion: The ECOS 16 was translated and culturally adapted to the Portuguese language, and the findings show that the questionnaire is a valid and reliable measure to assess the quality of life of women with postmenopausal lumbar osteoporosis.
