Cohort
study
|
All surviving from the original Rancho Bernardo cohort who still resided in southern California
|
≥ 45 years
|
|
396 men
|
|
|
|
|
To examine the independent association between dietary zinc and plasma zinc and the association of each with bone mineral density (BMD)
|
Age- and BMI-adjusted dietary and total zinc intakes were significantly lower in the men with osteoporosis at the spine than in men without osteoporosis at that location

population-
based
prospective
cohort
study
|
city of Malmo, in the southern part of Sweden
|
Aged
46-68 years
|
|
6576 men
|
The intakes in the lowest quintiles were 10 mg for zinc
Low zinc intake showed a threshold with increased fracture risk in the lowest decentile, corresponding to a zinc intake of 9.5 mg daily
|
A high proportion of the population, more than 20%, seems to be at risk of having inadequate dietary habits with respect to zinc
|
A lower fracture risk was noted in men with zinc intake in the second quintile [RR = 0.58 (0.34-0.99)] and fifth quintile [RR = 0.47 (0.25-0.89)] compared with the lowest decentile
|
|
To determine dietary risk factors for fracture in men aged 46-68 years
|
Inadequate intakes of zinc are important risk factors for fracture

Cross-
sectional
study
|
Rheumatology clinic in Tabriz, Islamic Republic of Iran
|
women > 50 years old who had been no menstruation for ≥ 6 months prior to entry into the study, having no history of hormone replacement therapy, other bone disease, kidney stones, endocrine disorders or any medical conditions that could influence on the mineral status
|
Use of mineral supplements, having history of hormone replacement therapy, bone disease, kidney stones, endocrine disorders or any medical conditions that could influence on the mineral status
|
A total of 51 post-menopausal women
|
The mean dietary intake (and percent from RDA) of zinc in post-menopausal women with low bone density was 3.82 ± 0.19 mg/day (48 ± 2.41% RDA)
|
|
|
|
To investigate and compare the mineral status between osteopenic and osteoporotic postmenopausal women in Tabriz, Islamic Republic of Iran
|
The mean dietary intake of zinc was significantly lower than recommended dietary allowance (RDA). No statistically significant differences were observed between the osteopenic and osteoporotic groups with respect to dietary intake of zinc
