Objectives:
Several epidemiological investigations have assessed the association between vegetable-based diet intake (VDI) and risk of osteoporosis in postmenopausal women, but the outcomes have been inconsistent. Therefore, this review article has been conducted.
Does vegetable-based diet intake reduce risk of osteoporosis in postmenopausal women?
Study design:
This review article included 10 studies with a total of 14,247 women.
Results and conclusions:
The investigators found when comparing with the lowest category of vegetable-based diet intake, the highest category of vegetable-based diet intake significantly reduced risk of osteoporosis in postmenopausal women with 27% [pooled OR = 0.73, 95% CI = 0.57-0.95].
Significantly means it can be said with a 95% confidence that highest category of vegetable-based diet intake really reduced the risk of osteoporosis in postmenopausal women with 27%.
The investigators found in case-control studies when comparing with the lowest category of vegetable-based diet intake, the highest category of vegetable-based diet intake significantly reduced risk of osteoporosis in postmenopausal women with 39% [OR = 0.61, 95% CI = 0.48-0.78].
However, this reduced risk was not significant in cross-sectional studies [OR = 0.82, 95% CI = 0.57-1.16].
Not significant because OR of 1 was found in the 95% CI of 0.57 to 1.16. RR of 1 means no risk/association.
The investigators found when comparing with the lowest category of vegetable-based diet intake, the highest category of vegetable-based diet intake significantly reduced risk of osteoporosis of the femoral region in postmenopausal women with 43% [OR = 0.57, 95% CI = 0.41-0.80].
The investigators found when comparing with the lowest category of vegetable-based diet intake, the highest category of vegetable-based diet intake significantly reduced risk of osteoporosis of the lumbar spine in postmenopausal women with 45% [OR = 0.55, 95% CI = 0.38-0.81].
The investigators found when comparing with the lowest category of vegetable-based diet intake, the highest category of vegetable-based diet intake significantly reduced risk of osteoporosis, based on the Dual energy X-ray absorptiometry (DEXA) measurement method in postmenopausal women with 28% [pooled OR = 0.72, 95% CI = 0.54-0.95].
The investigators concluded high vegetable-based diet intake reduces risk of osteoporosis in postmenopausal women, particularly in the femoral region and the lumbar spine.
