Bulimic Women

Objective: Data concerning bone mineral density (BMD) in bulimia nervosa are contradictory and include both low and normal values. The aim of the present study was to elucidate possible endocrine-and nutrition-related factors predicting BMD in bulimic women. Design: Cross-sectional study. Methods: Seventy-seven bulimic patients and 56 age- and body mass index (BMI)-matched healthy controls were examined with respect to BMD (dual energy X-ray absorptiometry) and to serum levels of hormones and metabolic factors. Results: Bulimics had significantly lower spinal BMD and higher frequency of osteopenia in the total body than controls. Furthermore, bulimic women had significantly lower levels of estradiol-17β and free thyroxine and significantly higher cortisol levels compared with controls. Among the bulimics, 31.2% had present menstrual disturbance, 51.9% had a history of amenorrhea and 23.4% had previous anorexia nervosa. Subgroups of bulimics with a history of amenorrhea and previous anorexia nervosa had significantly lower total and spinal BMD than controls, whereas those without such history did not differ from the controls. In univariate analysis, a history of amenorrhea, cortisol, testosterone, previous anorexia nervosa, and BMI showed significant associations with spinal BMD. Multiple regression analysis including all significant variables revealed previous anorexia nervosa to be the strongest determinant of spinal BMD, accounting for 34% of the variance, while associations between endocrine factors and BMI disappeared. Conclusions: Low bone mass in bulimics may be explained by previous anorexia nervosa, whereas endocrine variables related to BMD seem to be secondary determinants that are dependent on previous anorexia nervosa and BMI.

Abstract Background Psoriasis is considered as a systemic disease since it is an inflammatory skin disorder associated with increased level of many inflammatory cytokines, which can result in many comorbidities. It was hypothesized that there is an association between psoriasis and osteoporosis and many studies investigated this association, but the majority of them focused on the association between psoriatic arthritis and osteoporosis, while this study excluded psoriatic arthritis and investigated the association between psoriasis of different clinical varieties and osteoporosis. Objective to assess the associated relationship between psoriasis and osteoporosis in psoriatic patients of different clinical varieties, by measuring the prevalence of osteoporosis in a sample of these patients. Subjects and methods Our cross-sectional study included 42 psoriatic male and female patients with non specific ages, 48% of them were males (20 patients) and 52% of them were females (22 patients), and it excluded any patients with endocrinal disorders, chronic renal failure, liver cell failure, other chronic inflammatory disoredres, malabsorption, history of alcohol misuse, history of intake of steroids for longer than 6 months, pregnant women and psoriatic arthritis. All patients were subjected to a questionnaire for detailed history taking, complete general and dermatological examinations, evaluation of psoriasis severity by Psoriasis Area and Severity Index (PASI) score and bone mineral density (BMD) measurement using the DEXA method of the lumbar spine (L1L4) and femoral neck. Results The prevalence of osteoporosis among psoriatic patients was (9.5%), (10%) in males and (9%) in females, which was lower than the prevalence of osteoporosis in the population. While the prevalence of osteopenia was 50%, (45%) in males and (54.5%) in females, which was higher than the prevalence of osteopenia in the population. Additionally this study showed a statistically significant negative correlation between the age of the patients and BMD, and a highly significant positive correlation between the BMI of the patients and BMD, while there were non significant negative correlations between both (duration of psoriasis and PASI score) and BMD, and no significant correlations between clinical variants of psoriasis and BMD. Conclusion Psoriasis is associated with a decrease in the bone mineral density more in males, with higher incidence of osteopenia rather than osteoporosis. The decrease in BMD increases with increasing age, duration of psoriasis and PASI score, decreases with increasing BMI, while the clinical variants of psoriasis didn’t seem to affect the BMD of psoriatic patients.

Summary Objective: Vertebral fracture assessment (VFA) is a test technique that can be used to detect asymptomatic vertebral fractures (AVF). It uses dual energy X-ray bsorptiometry (DXA) and can be performed concurrently with bone densitometry. This study aims to assess the prevalence of AVF in patients with low bone mass. Methods: Cross-sectional study including 135 individuals with low bone mineral density (BMD) with a T-score < -2.0 standard deviation (SD) in a densitometry clinic located in the city of Blumenau (state of Santa Catarina). Anthropometric, clinical and lifestyle variables were obtained from history-taking and physical examination. Densitometric variables were obtained by bone mineral densitometry and VFA (Explorer, Hollogic®). Vertebral fractures were classified according to the Genant criteria. Student's t, chi-square and logistic regression were performed for statistical analysis. Results: AVFs occurred in 24.4% of the subjects. They were older compared to those without AVF (65±9.25 versus 60.1±8.66; p=0.005), and had a history of lowimpact fractures (38.24% versus 19.8%; OR 2.5; p=0.03). Half of the patients that reported steroid therapy had AVFs, compared to one fifth of those who did not use steroids (50% versus 21.49%; OR 3.6; p=0.01). Conclusion: Asymptomatic vertebral fractures were present in approximately one fourth of patients. The risk factors associated were history of low-impact fracture, use of steroids and age > 61 years.

This study assessed differences in bone-mineral density (BMD) and lean and fat tissues between 5 age groups of White men age 65–93 years. Lean and fat tissues were measured with absorptiometry and anthropometry, and BMD, with dual-energy X-ray absorptiometry. Forearm, spinal, and femoral T scores were used to classify BMD as normal, osteopenic, or osteoporotic. A questionnaire evaluated previous physical activity, calcium intake, and bone fractures. Significantly lower values in body weight, lean tissue, and forearm BMD occurred in the older age groups. Significant, positive relationships were found between total lean tissue and radial, spinal, and hip BMDs. For the total group, osteopenic and osteoporotic T scores, respectively, were femoral neck 70.6% and 9.8%, radius 27.5% and 25.5%, and spine 25.5% and 7.8%. Differences in BMD values were found between levels of lifestyle factors (dietary calcium and history of previous fractures). In conclusion, elderly men should be encouraged to maintain adequate total lean tissue because of its association with BMD.

Objective: To determine the related factors of osteoporosis in men. Subjects and Methods: Cross sectional study performed on 110 patients with osteoporosis and 104 subjects without osteoporosis, men aged 50 and over in Cho Ray Hospital and University Medical Center from 09/2013 to 03/2017. Diagnosis of osteoporosis by measuring bone mineral density by DXA according to criteria of World Health Organization. Data on anthropometry, history of smoking, fracture, alcoholism, physical activities and levels of β-CTX, osteocalcin, testosterone were collected. Result: The related factors for decrease in bone mineral density at femoral neck, total hip included dropped total testosterone, elevated β-CTX and reduced BMI. The related factors for decrease in bone mineral density at lumbar spine included dropped total testosterone, elevated β-CTX, reduced BMI and elevated androgen index. The results of analysis logistic regression showed the relationship between osteoporosis and testosterone (OR: 0.98; KTC 95% 0.97 - 0.99), β-CTX (OR: 1.05; KTC 95% 1.03 - 1.07). Logistic regression equation predicted the probability of osteoporosis was log(odds(P)) = -8.79 + 0.05*β-CTX -0.02*Testosterone. Conclusion: The related factors of osteoporosis in men include decreased total testeosterone, elevated β-CTX.

ObjectivesTo explore whether bone mineral density (BMD) is associated with arterial stiffness in middle-aged and elderly people with an advanced arterial stiffness index as indicated by the cardio-ankle vascular index (CAVI).DesignA cross-sectional study.SettingThis study was conducted from September 2015 to May 2017 at the geriatrics department of a provincial medical centre in China.ParticipantsA total of 580 patients aged 50 and over were enrolled in the study. The mean age of the group was 64.82±11.4 years, and 63.1% were male.Primary outcome measuresAssociations of age with CAVI values and BMD. Associations between BMD and CAVI values.ResultsWith increasing age, CAVI values gradually increased (p<0.001) and the femoral neck (FN) and total hip (TH) BMD gradually decreased (p<0.001, all). In the bivariate correlation analyses between the covariates and CAVI values, age and CAVI values showed the greatest positive correlation (r=0.631, p<0.001), and CAVI values were negatively correlated with FN BMD (r=−0.229, p<0.001) and TH BMD (r=−0.218, p<0.001). In the linear regression analyses, TH BMD (B=−1.812 (95% CI −2.475 to −1.149), p<0.001) and FN BMD (B=−1.968 (95% CI −2.651 to −1.284), p<0.001) were negatively correlated with CAVI values. After adjusting for age, gender, body mass index, smoking, history of cardiovascular or cerebrovascular disease, history of diabetes mellitus, systolic blood pressure, high-density lipoprotein cholesterol, blood uric acid, fibrinogen and estimated glomerular filtration rate, only TH BMD was still negatively correlated with CAVI values (B=−0.843 (95%CI −1.454 to −0.232), p=0.007). However, there was no consistent and significant correlation between lumbar spine BMD and CAVI values.ConclusionIn this cross-sectional study, a significant correlation between TH BMD and CAVI values was observed in middle-aged and elderly Chinese inpatients. However, our cohort was a small sample of inpatients, and prospective studies from more centres are expected.

SummaryThe present cross-sectional research was designed to study possible correlations between clinical reproductive factors and bone mineral density (BMD) values.Using the data gathered by the population-based Iranian Multicenter Osteoporosis Study (IMOS), we investigated the correlation found between reproductive factors and osteoporosis. Subjects were recruited from five major cities of Iran. Bone mineral density was measured using Dual-Energy X-ray Absorptiometry and the results were analyzed against the age at menarche and at menopause, number of pregnancies, children and abortions, and the history (and duration) of breastfeeding.Data was available for 2528 women. Gravidity and number of children were reversely correlated with BMD. Younger age at menarche was associated with higher BMD values, whereas there was no significant correlation between age at menopause and menstrual history and BMD.Our study suggests that clinical reproductive factors, particularly number of children and breastfeeding, could be incorporated as predictors of BMD levels in women. Given the controversial results obtained in different studies, longitudinal studies should be carried out to enlighten the importance of these factors and the rationale of their use to predict BMD values in different settings.
