Abstract

OBJECTIVE: To assess the impact of tea consumption on the risk of osteoporotic hip fractures. METHODS: Between January 2008 and June 2012, 581 (148 males, 433 females) incident cases of hip fractures were enrolled from four hospitals in Guangdong province, with 581 sex- and age-matched (± 3 years) controls from either hospitals or communities. Face-to-face interviews were conducted to collect data pertaining to tea drinking and various covariates. RESULTS RESULTS: from univariate conditional logistic analyses showed that an inverse association was observed in tea drinking and hip fracture risk. Longer time, greater frequency and dosage of tea consumption were dose-dependently associated with lower risk of hip fractures (P-trend < 0.05). Compared to non-drinkers, the odd ratios related to regular tea drinkers, subgroups with different length, frequency, dosage, type of tea consumption were ranged between 0.54 and 0.74 (all P < 0.05). After adjustment for factors as age, daily energy intake, BMI, education levels, passive smoking, calcium supplement and physical activity, the dose-dependent associations among above said factors still remained significant. However, the strength of the association lowered slightly. The beneficial effect of tea was significant only in men but not in women. Similar effects were found in subjects with different education levels. CONCLUSION: Regular tea drinking habit might decrease the risk of osteoporotic hip fractures in the elderly males.
