Objectives:
Current studies evaluating the association of tea consumption and bone mineral density (BMD) have yielded inconsistent findings. Therefore, this meta-analysis (review article) has been conducted.
Does tea consumption increase bone mineral density?
Study design:
This review article included 4 cohort, 1 case-control and 8 cross-sectional studies including a total of 12,635 cases (6,059 in the tea consumption group and 6,576 individuals in non-tea consumption group).
Results and conclusions:
The investigators found tea consumption significantly reduced the occurrence of low bone mass with 34% [OR = 0.66, 95% CI = 0.47-0.94, p = 0.02].
The investigators found tea consumption significantly yielded higher mineral densities in several bones, including:
-the lumbar spine [standardized mean difference (SMD) = 0.19, 95% CI = 0.08-0.31, p = 0.001];
-hip [SMD = 0.19, 95% CI = 0.05-0.34, p = 0.01];
-femoral neck [mean difference (MD) = 0.01, 95% CI = 0.00-0.02, p = 0.04];
-Ward triangle [MD = 0.02, 95% CI = 0.01-0.04, p = 0.001] and;
-greater trochanter [MD = 0.03, 95% CI = 0.02-0.04, p 0.00001]
than the non-tea consumption group.
The investigators concluded that tea consumption increases bone mineral density, especially in the lumbar spine, hip, femoral neck, Ward triangle and greater trochanter, which can prevent bone loss.
