This study purposed to investigate the relationship between physical activity level and bone mineral density (BMD) in the elderly of Amirkola in northern Iran. This cross-sectional study was part of a proposal to assess the situation of the elderly in Amirkola (AHAP) (Amirkola Health and Ageing Project) conducted on 1113 elderly individuals (616 males and 497 females) in Amirkola city. Physical activity was measured using a standard questionnaire of physical activity in the elderly (Physical Activity Scale for Elderly). Mineral bone mass was measured using dual energy X-ray absorptiometry in the femur neck and lumbar spines, and vitamin D levels were measured in morning blood samples. T-test, ANOVA, Pearson correlation, and linear regression tests were used to analyze data. The mean physical activity of women (118.6±55.5) was higher than that of men (110.3±71.1) (p=0.035). This study found a significant positive relationship between total physical activity and femur bone mineral density (p=0.001 and r=0.101), but this association was not significant in lumbar spines (p=0.597 and r=0.016), though bone mineral density increased in both areas with increased physical activity (p=0.098). A significant inverse relationship between age and physical activity (p=0.001) and between age and bone mineral density (p=0.001) was observed. Analyzing the influencing variables using the linear regression model indicated physical activity, age, and BMI had significant relationships with bone mineral density in the femur, but neither vitamin D nor calcium played a role. Given the positive correlation between bone mineral density and physical activity, it can be concluded that low intensity weight-bearing activities carried out in compliance with safety rules may be suitable for the elderly.

“…The difference was maximum for Caucasians and the values were 12.67% higher in the 40-50 age group and 10.81% higher in the 50-60 age group. But what is interesting to note here is that even within Asian population, Indian women in the studied age group fare much below their Korean and Iranian counterparts [24,25]. This difference between sBMD spine was more evident in age group 40-50 as compared to 50-60 years.…”

The study investigates BMD pattern in Indian women aged 40-60 years through a retrospective assessment using DEXA scan of hip and spine of 1,282 asymptomatic Indian women. The Study group indicated high incidence of decreased bone mass and significantly lower BMD as compared to western and other Asian counterparts. Introduction An understanding of BMD pattern in women aged 40-60 years is crucial for prevention, diagnosis of osteoporosis and management of its complications in later life. Hence, the present study investigates BMD in Indian women aged 40-60 years for which no data exists in literature. Method A retrospective assessment of BMD by DEXA scan of hip and spine of 1,282 asymptomatic women in age group 40-60 was performed. Standardized BMD was calculated and compared with other population groups. Results Osteoporosis and osteopenia are widely prevalent among females of the 40-60 age group as a meager 35% of subjects had normal bone density. Average BMD of spine was 0.89 (SD 0.14) gm/cm 2 and average BMD of hip was 0.85(0.15) gm/cm 2 . The correlation between BMD and age was negative. Spine DEXA was found to be more significant than hip DEXA (p value<0.0001) for osteoporosis assessment. Similarly, T scores of spine were more significantly correlated in this age group (p value<0.0001) for osteoporosis than hip T scores. Conclusion The study group indicated high incidence of decreased bone mass, and significantly lower BMD as compared to western and other Asian counterparts. This study emphasizes on early screening and treatment in study group to avoid long-term complications.

“…Evidences show that peak bone mass among all age groups of Iranian population, is lower than European or American populations [6]. A high prevalence of fractures due to osteoporosis was reported, in some less developed areas in Iran especially in low income groups [7-9].…”

Educational difference in the prevalence of osteoporosis in postmenopausal women: a study in northern Iran

2011

BackgroundOsteoporosis is the most common metabolic bone disease in the world and it is rapidly increasing in Iran. In this study the relationship between educational levels and osteoporosis was investigated among Iranian postmenopausal women.Method and subjectsSeven hundred and six women aged 50-75 years old were randomly recruited from urban (n = 440) and rural (n = 266) areas in Guilan. Osteoporosis was diagnosed by quantitative ultrasound technique and dual X-ray absorptiometry. Serum 25(OH) D3, body weight and height were measured in all subjects. Other data including age, educational level, menopause age, medications and history of illness were also collected.ResultsWe found that the prevalence of osteoporosis was significantly greater among women with low educational level than women with high educational status (18.0% vs 3.8% P < 0.0001). However, women with low educational level had higher mean serum level of vitamin D than women with high educational level. Osteoporosis was significantly more prevalent among women living in rural areas than women living in urban areas (19.1% v.s 13.3%, P < 0.0001).ConclusionThis study showed that educational level is associated with bone health in this population of postmenopausal women with significantly higher osteoporosis found in lower social groups. Therefore, we suggest that women with low social level should be carefully evaluated for signs of osteoporosis during routine physical examinations.
