Aims: Previous study reported positive association between BMD and hand grip strength in Taiwanese elders living in long-term care facility. The aim of this study was to examine the relationship between BMD and various physical perfor- mances in community-dwelling elders in Taiwan.

Methods: A cross-sectional study was conducted in elders living in 8 administrative Lis at north district of Taichung City in 2009. A total of 838 elders (392 women and 446 men), aged 65–94 years old, were recruited. BMD and appendicular skeletal muscle mass are measured by DXA (GE-Lunar DPX Pro, Lunar Corporation, Madison, WI, USA). Low bone density was de- fined as: (1) osteopenia: a BMD value between 1 and 2.5 SD below the mean of men or women age 20–29 years as reference group. Physical performances including balance (one leg limb stand), physical function (gait speed, 20-s chair stand test, timed up and go test and 5-min walk test) are measured for each elder.

Results: The prevalence of normal, osteopenia and osteoporosis was 51.3 %, 35.1 % and 13.6 %, respectively. The mean walking meters of 6-min walk test for normal, osteopenia and osteoporosis groups were 433.7±129.4, 432.8±110.0 and 384.3±159.1, respec- tively. The mean of grip strength for normal, osteopenia and oste- oporosis groups were 28.9±8.3, 26.0±7.7 and 22.1±7.9, respec- tively. We observed elders with osteopenia and osteoporosis had worse flexibility, 5-min walk test and grip strength than those with normal BMD by using linear regression models with adjustment for age, sex, body composition, exercise behavior, and comorbidity.

Conclusions: We conclude that osteopenia and osteoporosis elders have greater loss in flexibility and physical function than those with normal BMD.

Aims: To investigate the prevalence and factors associated with low back pain among adults in Taiwan.

Methods: The National Health Interview Survey, a cross- sectional study, was conducted from October 2002-March 2003 to gather data from 24,435 adults aged 20 years and older selected randomly from Taiwan’s general population.

Participants with history of low back pain were assessed using a comprehensive questionnaire. Additional assessment of os- teoporosis diagnosed by physician was also evaluated.

Results: Among the 24,435 adults, 25.7 % had reported low back pain within the past 3 months. Factors associated with low back pain included female gender (odds ratio (OR)=1.67, 95%CI=1.43–1.95), low education (OR=1.38, 95%CI=1.23–

1.55), and blue-collar work (OR=1.16, 95%CI=1.07–1.26).

Patients with osteoporosis were more likely than those without osteoporosis to have low back pain (OR=2.55, 95%CI=2.33 – 2.78) or frequent low back pain (OR=4.15, 95%CI=3.66–

4.70). The ORs of frequent low back pain in association with osteoporosis in men and women were 5.77 (95%CI=4.66 – 7.15) and 3.49 (95%CI=2.99–4.07), respectively.

Conclusions: Low back pain is prevalent among Taiwanese adults and is associated with osteoporosis.

Aims: To determine the vitamin D status in apparently healthy pregnant Kashmiri women, and whether the recom- mended daily allowance for vitamin D in pregnancy is suffi- cient to maintain a normal vitamin D status in this population.

Methods: 165 consenting pregnant women attending the an- tenatal clinic of the Department of Obstetrics & Gynecology of our Institute were enrolled. All subjects underwent a detailed history and physical examination as per a preformed proforma.
