“…In contrast, much of the world's population has a calcium intake <500 mg/day (10) , e.g. the intake in Japan is 400–500 mg/day due to a diet of mainly soybean, small fish with bone and vegetables (19) . The calcium intake is even lower in other Asian countries and in Africa.…”

Background: Dietary calcium intake is assumed important in the prevention and treatment of osteoporosis. However, people in countries with a high calcium intake from commodities such as milk and milk products have a high incidence of hip fracture. The effect and influence of calcium intake in the prevention of osteoporotic fracture vary from different studies. Objective: To investigate premorbid daily calcium intake in patients with low energy hip fractures during four consecutive years. Design: In total 120 patients (mean age 7898.5 (SD) years) were included between 2002 and 2005. The patients answered a structured food frequency questionnaire (FFQ) and interviews on patients' daily calcium intake from food and supplements took place during a 6-month period before the fracture. Dual energy X-ray absorptiometry (DEXA) was performed in a subgroup of 15 patients. Results: The mean daily calcium intake from food and supplementation was 9709500 mg. However, 38% of patients had an intake below the recommended 800 mg/day. There was no significant relationship between calcium intake and age, gender, bone mineral density, serum calcium or albumin, type of fracture or body mass index. The mean free plasma calcium concentration was 2.390.1, i.e. within the reference limit. In 2005, 80% of the patients who underwent DEXA had manifest osteoporosis. There was a trend towards decreased calcium intake over the observation period, with a mean calcium intake below 800 mg/day in 2005. Conclusion: Hip fracture patients had a mean calcium intake above the recommended daily intake, as assessed by a FFQ. However, more than one-third of patients had an intake below the recommended 800 mg/day. The intake appeared to decrease over the investigated years. The relationship between calcium intake and fracture susceptibility is complex.

“…Calcium is an essential nutrient for critical biological functions, such as nerve conduction, muscle contraction and structural support of the skeleton. Studies show that, among Japanese women, plants and fish contributed 46.7% of total dietary calcium, whereas 32.4% was derived from milk. Japanese people are accustomed to traditional dishes, such as fish, especially small fish eaten with soft and edible bones, like sardines and smelts.…”

Aims/IntroductionAlthough male diabetic patients have an increased risk of fracture, there is little information about this in the literature. The association between heel bone stiffness and the lifestyle of male patients with diabetes was evaluated.Materials and MethodsThe study included 108 participants with type 2 diabetes mellitus patients and 168 age-adjusted, healthy male volunteers. None of the participants had a history of osteoporosis or other severe diseases. Heel bone stiffness was examined by quantitative ultrasound, and each participant completed a health interview survey questionnaire. Bone stiffness was taken as an indicator of bone strength. Stepwise regression analysis was used to investigate associations between bone stiffness and lifestyle-related factors, such as sunlight exposure, intake of milk or small fish, regular exercise, cigarette smoking, consumption of alcohol, and number of remaining teeth.ResultsBone stiffness showed a significant negative association with cigarette smoking [standardized coefficient (SC) = −0.297, F-value (F) = 10.059] and age (SC = −0.207, F = 7.565) in diabetic patients. Bone stiffness showed a significant negative association with age (SC = −0.371, F = 12.076) and height (SC = −0.193, F = 7.898), as well as a significant positive association with sunlight exposure (SC = 0.182, F = 9.589) and intake of small fish (SC = 0.170, F = 7.393) in controls.ConclusionsThese findings suggest that cigarette smoking and age are negatively associated with bone stiffness in Okinawan male patients with type 2 diabetes mellitus.

“…In Asia, 50–100% of the population is lactose intolerant [155] and thus may be at risk for calcium inadequacy. Apart from supplements, fish can be a good source of calcium [156] , and a higher fish intake results in a higher BMD [157] , [158] . Fatty sea fish is especially a good source of vitamin D and n-3 polyunsaturated fatty acid which are beneficial for bone health.…”

Osteoporosis in East Asia: Current issues in assessment and management

The greatest burden of hip fractures around the world is expected to occur in East Asia, especially China. However, there is a relative paucity of information on the epidemiology and burden of fractures in East Asia. Osteoporosis is greatly under-diagnosed and under-treated, even among the highest-risk subjects who have already suffered fractures. The accessibility to bone densitometry, the awareness of the disease by professionals and the public, and the use and reimbursement of drugs are some of the areas which need improvement especially. Cost-effective analysis on screening strategy and intervention thresholds based on local epidemiology data and economic status are available only in Japan. In addition, clinical risk factor models for the assessment of fracture probability may be ethnic specific. Further research is needed to develop a cost-effective risk assessment strategy to identify high-risk individuals for screening and treatment based on local data. Moreover, inadequate calcium and vitamin D intake is still an issue faced by this region.
