Abstract

Background: Tea consumption is common throughout the world, especially in Iran and it was known as the most common beverages. Several studies evaluated negative effect of coffee and relationship between its caffeine content with bone density. But relationship between tea drinking and bone mineral density is less observed. Considering high amount of tea consumption and prevalence of osteoporosis in Iran, it is important to investigate this relationship.

Materials and Method: Population study includes 1125 subjects (aged 20- 72 years) randomly selected by cluster sampling in Bushehr, who participated in general project of prevention and treatment of osteoporosis. The participants were categorized based on degree of tea consumption: high tea drinkers (more than 4 cups of tea per day) and low tea drinkers (equal or less than 4 cups of tea per day).

Results: In high tea drinkers, mean score for bone density was significantly higher in neck and total femur. But this difference in isolated groups (according to sex, age and both of them) was not seen.

Conclusion: The result of this study indicates on a direct relationship between tea drinking and increasing of bone mineral density. Moreover, it shows the prevalence of osteoporosis is lower in people who have a regular daily habit of tea consumption
