BackgroundVertebral fractures could lead to reduced physical, social and mental functioning, and loss of personal independence. Therefore, during the treatment of osteoporosis, it has become necessary to examine the changes in everyday functioning, well-being and health related quality of life (HRQOL). To that effect, this study aims to translate, culturally adapt, and validate the Serbian version of Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41) for patients with vertebral fractures.MethodsNine female patients with osteoporosis participated in the pre-validation study. A validation, case–control study included two groups of female patients: one that consisted of 50 female patients with osteoporosis, and with at least one vertebral fracture, and another one that consisted of 50 control patients with osteoporosis but without fractures. They completed the QUALEFFO-41 and the EuroQol group questionnaire with five dimensions (EQ-5D) twice within a month. The validation study examined internal consistency, concurrent validity, test-retest reliability, sensitivity and specificity.ResultsDuring the pre-validation study, three of the items in the QUALEFFO-41 were slightly changed. Afterwards, during the validation study, the statistically significant differences (adjusted for: age, duration of menopause, current employment and marital status) in the mean values of all domains and total scores between the groups were noted. For the case group, the internal consistency of the QUALEFFO-41 domains and of total questionnaire was above 0.70. The test-retest reliability was tested by the intraclass correlation coefficients (ICC) that were in range 0.87 – 0.96 for the case, and 0.15 – 0.83 for the control group. Correlations between the total scores of the QUALEFFO-41 and the EQ-5D health state value, for both groups were negative and statistically significant (r = -0.78, p<0.001 and r = -0.73, p<0.001, respectively). The QUALEFFO-41 had a better prediction of the value of HRQOL of cases compared to the generic questionnaire EQ-5D (the AUC difference was 0.099, p = 0.013).ConclusionsThe Serbian QUALEFFO-41 version is reliable, valid, sensitive and predictive for examinations of HRQOL in patients with prevalent vertebral fractures and can be used in further studies.

AbstractThe aim of the paper was to examine the relation between bone density and certain parameters of lipid status in postmenopausal women. The research involved 300 women referred to densitometric examination as they belonged to the risk group of postmenopausal women. All the examinees had the following biochemical parameters determined: total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, glycemia, serum Ca and P. Univariate logistic regression analyses showed that each year of age, menopause duration, AH are significantly connected to risk increase for the appearance of osteopenia or osteoporosis. Increase in values of SBP, DBP, cholesterol, LDL and triglyceride are connected with significant risk increase for the appearance of osteopenia or osteoporosis. Patients with AH are connected to 11 times elevated risk for the appearance of osteopenia or osteoporosis, cigarette smoking increased the risk by seven times, physical inactivity even by 52 times, CVD in the family anamnesis by eight times, and osteoporosis in the family anamnesis is connected to the risk by four times. In our research, atherogenic lipoproteins negatively correlate with lumbar bone density. Disturbed lipide status is a risk factor for cardiovascular diseases, but also a risk factor for the appearance of osteoporosis.

Functional status evaluated by the HAQ is a standard for as- sessment of RA due to its convenience and good correlation with parameters of disease activity. The most significant factors that increase the odds that the patient has the greatest functional damage are DAS28 SE, DAS28 CRP and the pres- ence of CRP.

SummaryBy determining the prevalence of postural disorders among eighth grade school students it is possible to indicate the state of these disorders at the end of the elementary school level of education, and compare it to the results obtained by applying corrective treatments on high school students. Thus, the aim of the research was to determine the prevalence of postural disorders among eighth grade school children. The research was carried out on a sample of 101 eighth grade students of both genders, aged 14. The photometry method was used to determine the presence of any postural disorders. The research results indicated that a proportionally statistically significant large number of participants with postural disorders were identified. Of the total number of participants, 60.4% had postural disorders, the most prevalent of which was flat back (22.8%), kypho-lordosis, (20.8%), lordosis (9.9%) and kyphosis (6.9%). Analyzed in terms of gender, the percentage of the girls with postural disorders is statistically significantly greater than that of the boys. Due to the large number of children with postural disorders, the recommendation is that the evaluation of the postural status of students should take place not only at the elementary school age, but also at the high school age. In addition, evaluation alone is insufficient, and exercise programs to correct postural disorders are required as well.
