The study also confirms that better bone density is associated with a lower risk of fracture. This prospective study, which began in 1988, followed 764 men and women with a mean age of 77 over an average period of 12 years in Framingham (Massachusetts, USA).
The participants completed a semi-quantitative food-frequency questionnaire, enabling the researchers to evaluate their milk intake. The mineral density of their femoral neck bone was also measured. During the follow-up period, 97 femoral neck bone fractures were recorded. After adjustments for various confounding factors, people with medium (>1 and Intake of yogurt and milk also lowered the risk of fracture in the same proportions as milk on its own. These results also demonstrate that there is a weak but significant link between better bone density and lower risk of fracture.
