Calcium intake in a Swedish adult population: relationship to life-style factors and bone mineral density. A descriptive study
(English)Manuscript (preprint) (Other academic)
Background. This study is part of a community-based intervention programme dealing with the prevention of osteoporosis. The study aims were to estimate the calcium intake from dairy products and calcium supplements within a general population, and thereafter to study associations between calcium intake, relevant lifestyle factors, and forearm bone mineral density.
Methods. A randomised sample of 15 % of the inhabitants aged 20 - 79 years ( = 1510) from two Swedish municipalities answered a questionnaire, and a selected sub-sample (n=448) had their forearm bone mineral density measured.
Results. The mean consumption of calcium from dairy products was 878 mg/day. Men consumed more than women, and calcium intake decreased with increasing age. Twelve percent of the youngest age group in the study population and 31 % of the oldest age group did not meet the recommended daily intake. Associations were found between calcium intake and both residence and physical activity. There was a tendency towards an association between calcium intake and forearm bone mineral density. No other associations with lifestyle factors were observed.
Conclusion. Calcium intake is in general well attained in an adult Swedish population, although the intake range is wide (55 to 3213 mg/day from dairy products). Women aged 50-59 years and older people are at increased risk of not meeting the recommended daily intake.
