Objectives: Assessment of the disease acceptance level in women with osteoporosis depending on selected sociodemographic factors. Material and Methods: The study included a group of 198 women, aged M±SD 72.3±8.59 years, diagnosed with postmenopausal osteoporosis and treated in 2 Osteoporosis Treatment Centres in Łódź. A questionnaire survey and Acceptance of Illness Scale (AIS) were applied in the study. Based on the questionnaire, the authors collected sociodemographic data (including age, marital status, place of residence, financial status) which the authors subsequently analyzed using a statistical program. Results: The respondents living in the countryside, with primary education and a very difficult financial situation manifested a low disease acceptance level. The authors have shown that postmenopausal osteoporosis acceptance level significantly depends on the age (p = 0.0024), place of residence (p = 0.0044), education (p < 0.001) and affluence (p = 0.0049), however, it is not related to duration of the disease. Conclusions: Postmenopausal osteoporosis acceptance level depended on age, place of residence, education and affluence level, however, it was not related to the disease duration. Psychological aspects, including assessment according to the disease acceptance scale, constitute a factor influencing mental health, therefore they should be included in evaluation of therapy effectiveness in patients chronically treated for osteoporosis.
