title: [Are food intake and life styles related with bone mass in fertile women?].
abstract: BACKGROUND
  To study the relationship between current and adolescent calcium intake and bone mineral density (BMD) in 76 premenopausal women of 42 y. with regular menses and without pathologies associated with body weight, body morphology or BMD.
  
  
  METHODS
  Was measured: the lumbar and femoral BMD by dual energy X-Ray absorptiometer, calcium and protein intake by a week frequencies questionnaire, and calciuria. Obesity, exercise, alcohol, tobacco and family history of osteoporosis were considered. Levels of BMD < -1SD was considered as osteopenia.
  
  
  RESULTS
  Calcium intake average was 989 mg/day, 62% by dairy. Twenty-five percent presented osteopenia in some bone site. BMD was not correlated with calcium or protein intake, calcium/protein nor calciuria. No differences was found between normal and osteopenic group for any of the studied variables, except lower body mass index in the femoral osteopenic group. Those women who decreased the calcium intake from adolescence had 8.2% less femoral BMD tha those who increased the consumption (p = 0.05).
  
  
  CONCLUSIONS
  Current and adolescent calcium intake, family history of osteoporosi calciuria, and exercise have not found useful as screening of osteopenia in premenopausal women with moderated exercise level and low consumption of alcohol and tobacco.
