Peak bone mass, which can be defined as the amount of bone tissue present at the end of the skeletal maturation, and also it is an important determinant of osteoporotic fracture risk. The peak bone mass of a given part of the skeleton is directly dependent upon both its genetics and environmental factors. Therefore, the aim of the proposed research is a comprehensive systematic assessment of the pattern of peak bone mass in different countries across the globe. The present article explains the protocol for conducting such a research

The study of bone mineral density in postmenopausal women with rheumatoid arthritis

زمینه و هدف: کاهش تراکم مواد معدنی موجب بروز پوکی استخوان و عوارض ناشی از آن می شود. مطالعه حاضر با هدف بررسی وضعیت تراکم معدنی استخوان بر اساس رده های مختلف سنی در زنان یائسه مبتلا به آرتریت روماتوئید انجام شده است. روش بررسی: مطالعه توصیفی-تحلیلی حاضر، بر روی 98 زن یائسه مبتلا به آرتریت روماتوئید مراجعه کرده به بیمارستان آموزشی درمانی 5 آذر شهرستان گرگان که نتایج سنجش تراکم استخوانی آنان در پرونده موجود بود، انجام شد. اطلاعات لازم به وسیله پرسشنامه از پرونده های بیماران استخراج گردید. داده ها با استفاده از آزمون های آماری آماره های توصیفی (فراوانی نسبی و فراوانی مطلق، میانگین و انحراف معیار) و آزمون های تحلیلی (رگرسیون، کای دو، ضریب همبستگی اسپیرمن و ANOVA)، مورد بررسی قرار گرفت. یافته ها: در مجموع 98 زن یائسه مبتلا به آرتریت روماتوئید با میانگین سنی39/9 ± 88/57 سال مورد بررسی قرار گرفتند. شیوع کلی استئوپروز 3/13 گزارش شد که با افزایش سن به طور معنی‌داری افزایش یافت (001/0

Effect of Exercise Training on Bone Mineral Density in Post-menopausal Women : A Systematic Review and Meta-Analysis of Intervention Studies

Osteoporosis is a major health problem in post-menopausal women (PMW). Exercise training is considered a cost-effective strategy to prevent osteoporosis in middle aged-older people. The purpose of this study is to summarize the effect of exercise on BMD among PMW. A comprehensive search of electronic databases was conducted through PubMed, Scopus, Web of Science, Cochrane, Science Direct, Eric, ProQuest, and Primo. BMD changes (standardized mean differences: SMD) of the lumbar spine (LS) femoral neck (FN) and/or total hip were considered as outcome measures. After subgroup categorization, statistical methods were used to combine data and compare subgroups. Seventy-five studies were included. The pooled number of participants was 5,300 (intervention group:n= 2,901, control group:n= 2,399). The pooled estimate of random effect analysis was SMD = 0.37, 95%-CI: 0.25-0.50, SMD = 0.33, 95%-CI: 0.23-0.43, and SMD = 0.40, 95%-CI: 0.28-0.51 for LS, FN, and total Hip-BMD, respectively. In the present meta-analysis, there was a significant (p<0.001), but rather low effect (SMD = 0.33-0.40) of exercise on BMD at LS and proximal femur. A large variation among the single study findings was observed, with highly effective studies but also studies that trigger significant negative results. These findings can be largely attributed to differences among the exercise protocols of the studies. Findings suggest that the true effect of exercise on BMD is diluted by a considerable amount of studies with inadequate exercise protocols.Peer reviewe

Oral health-related quality of life and depressive symptoms in adults: longitudinal associations of the English Longitudinal Study of Ageing (ELSA)

Abstract Background Little is known about the relationship between oral health status and depressive symptoms in adults in England. The aim of this study was to examine the longitudinal association between oral health parameters and depressive symptoms in adults in England. Methods Data were obtained from the English Longitudinal Study of Aging (ELSA), which included information on self-rated oral health, oral impairment in daily life (Oral Impacts on Daily Performances, OIDP), and depressive symptoms (Center for Epidemiologic Studies Depression Scale, CES-D) in 6790 adults aged ≥ 50 years. Wave 3 data were used as baseline, while Waves 5 and 7 were used for follow-up assessments. Logistic regression was used to determine whether depressive symptoms at baseline anticipated self-rated oral health and OIDP and whether oral health status (at baseline) was associated with the development of depressive symptoms at follow-up assessment. Results Participants with poor self-rated oral health were at higher risk of developing depressive symptoms, even after adjusting for behavioral, clinical, and sociodemographic characteristics (OR = 1.69, 95% CI 1.38–2.07). Similarly, having oral impacts on daily performances were associated with the development of depressive symptoms: The OR for developing depressive symptoms at Wave 5 or 7 was 2.19 (95% CI 1.62–2.96) after adjustment for all covariates. Participants with depressive symptoms at baseline were more likely to report poor self-rated oral health (OR = 1.93, 95% CI 1.52–2.44) or one or more oral impacts (OR = 1.86, 95% CI 1.45–2.40) at follow-up than those without depressive symptoms at baseline, even after adjusting for confounders. Conclusions In the present study, a bidirectional association was found between depressive symptoms and poor oral health in older adults. Maintaining good oral health in older adults may be a protective factor against depressive symptoms. Therefore, more attention should be paid to promoting oral health awareness in older adults, including encouraging regular dental checkups, proper toothbrushing and flossing techniques, and healthy lifestyles
