Higher sea fish intake is associated with greater bone mass and lower osteoporosis risk in postmenopausal Chinese women
Osteoporosis International, 08/12/09

Chen YM et al. – Study reports that the higher intake of sea fish is independently associated with greater bone mass and lower osteoporosis risk among postmenopausal Chinese women.

Methods

Aim was to investigate the association of the intakes of different types of fishes with bone mineral density (BMD) and bone mineral content (BMC) and osteoporosis risk
A population-based cross-sectional study conducted among 685 postmenopausal Chinese women
Habitual dietary intakes assessed using food frequency questionnaire
BMD and BMC at the whole body, lumbar spine, and left hip were measured with DEXA

Results

After adjusting for the potential confounders, a dose-dependent relations between sea fish intake and BMDs, BMCs, and osteoporosis risk was observed
Mean BMDs were 3.2-6.8% higher, and BMCs 5.1-9.4% higher in the top quintile groups (Q5) of sea fish intake vs bottom quintile (Q1) at the whole body and hip sites
Odds ratios for osteoporosis in Q5 were 0.23, 0.12, and 0.06 vs those in Q1 at the whole body, total hip, and femur neck, respectively
No independent association between consumption of freshwater fish or shellfish and bone mass was observed
