Increased calcium intake has been associated with lower body weight, BMI and adiposity, mostly in children, youth and women. In men results are inconclusive. In this study the relation between calcium intake and body weight and body fat in obese men was investigated. 200 men, the mean age 45,1 ± 9,4 y, the mean BMI 33,2 ± 4,8 kg/m2, were divided into 4 groups on the basis of their calcium/protein index. No significant differences in body weight, BMI, fat mass, percentage of body fat were found across subgroups and no significant correlations between calcium intake and body variables were stated. This study did not confirm the association between calcium intake and body weight and adiposity in men.

The aim of the study was to prepare a tool for quantitive evaluation of calcium intake and its calibration. The ADOS-Ca test calibration was carried out by the 24-hour recall method repeated seven times. The study included 90 people (aged 22.6±0.1) who gave complete information, i.e. 630 nutrition interviews and 90 ADOS-Ca tests. Calcium intake from dairy products estimated by the test was stated in mg/person/day and was estimated on the basis of the consumed products amount, intake frequency indices and calcium content in 100 g of a product. Calibration included comparing the mean calcium intake (dependant-sample t-test, correlation coefficient) and compatibility of population distribution (chi2 test) in calcium intake classes (<66.7% of the Polish RDI at the safe level = calcium deficiency risk; 66.6-90% of RDI = no calcium deficiency risk; >90% of RDI = no calcium deficiency risk). Moreover sensitivity, specificity and accuracy indices were calculated for the prepared test. No differences between mean calcium intake from dairy products estimated by the ADOS-Ca test and the 24-hour recall method repeated seven times (men: 619 mg vs. 661 mg; p=0.263; women: 434 mg vs. 442 mg; p=0.645) were revealed, but calcium intake correlation was noted. No differentiation in the population distribution in three calcium intake classes was noted, and the percentage of people classified accurately into the same class by the ADOS-Ca test and the 24-hour recall method repeated seven times was high (71% of the population). The noted high sensitivity index value (88%), shows high ability of the test to classify people properly to a group under calcium deficiency risk. The prepared ADOS-Ca diagnostic test was proved to be a good tool for quantitive evaluation of calcium intake from dairy products and enabled accurate classification of people with different calcium intake with regards to risk of its deficiencies.

Background. This study analysed the correlation between characteristic dietary and non- dietary factors of fracture risk in women and mineral density of bone tissue (BMD). Material and methods. The study involved examination of 172 women, aged between 32 and 59. Calcium intake from a daily diet was determined with the use of the semiquantitative food consumption frequency method. The physical activity of the women was expressed in MET-minutes/week. BMD was determined by double-energy X-ray absorptiometry (DXA). The frequency of bone fracture and osteoporosis risk factors was determined and a 10-year risk of fracture (RB-10) was individually diagnosed according to the WHO and IOF criteria (2007). A high level of fracture risk (RB-10 > 14%) was assumed according to the Johnell's algorithm [2005], Results. The most frequent factors of fracture risk in women included: bone pains (76% of the total sample), inadequate calcium intake (43%), smoking (24%), previous fractures (24%), incidence of chronic diseases (22%), menstrual disorders (19%), family history of osteoporosis (17%), low physical activity (15%) and the incidence of thyroid disorders (10%). 85% of women had at least one factor of 10-year absolute risk of fracture. None of the examined women consumed a sufficient amount of calcium and the average calcium intake level was low (median of about 400 mg/day). Bone mineral density did not reveal any relationship with current intake of calcium by women, but depended on the consumption of dairy products in the past. Conclusions. Daily consumption of dairy products in childhood and in the school period was conductive to a higher mineral density of bone tissue in women. Advanced age and the occurrence of menstrual disorders were conductive to a lower mineral density of bone tissue in women. Women with low bone mineral density (lower BMD tertile) more frequently used supplementation with preparations containing calcium (25%) and more often had at least one RB-10 risk factor (93% of the sample).

Background. Dairy products provide the most important source of calcium in a typical human diet, being of particular significance to women. Objective. To determine dietary calcium intakes in a group of female students studying human nutrition at a Warsaw University of Life Sciences –SGGW through analysing the selections made of dairy products. Materials and Methods. A food frequency questionnaire was used to assess average consumption of dairy products. Total daily calcium intakes were then estimated by adding the intakes obtained from such dairy products to an average non-dairy calcium value obtained from other foodstuffs and taken to be 250 mg. Results. Varied choices were made of dairy foodstuffs, with most subjects consuming milk, milk beverages, cottage cheese and rennet cheese. Calcium intakes were thus dependent on the dietary assortment of such selected dairy products made. Whenever cheeses were avoided in the diet, then low calcium intakes became more common. Conclusions. When compared to dietary recommendations, calcium intakes in this group of young women were inadequately low, especially for those not eating cheese and despite supposedly having sufficient knowledge through studying this subject area.

Background. In many European countries a trend to eliminate milk and dairy products from everyday diet may be observed with increasing frequency. Elimination of milk and dairy products from the diet is connected with a reduced supply of calcium required for normal growth and development in children and adolescents Material and methods. The aim of the study was to assess calcium intake related with the consumption of milk and dairy products by children and adolescents aged 10-18 years in Europe, particularly Poland. Respondents came from families of a good socioeconomic position, were aware of principles of rational nutrition and could freely consume dairy products. Results. Based on conducted investigations it was found that calcium intake by respondents in Poland was 297.2 mg/day, at a European mean of 493.6 mg/day (575.2 mg/day/person S, 411.9 mg/day/person $). Calcium supply in individual countries is not correlated with the amount of consumed milk and dairy products. The biggest amounts of milk and dairy products are consumed by children and adolescents in Croatia (1396.2 g day/person), while the lowest in Germany (378.5 g/day/person). In Poland the consumption of milk and dairy products is 413.5 g/day/person. Conclusions. Conducted investigations showed a very low calcium intake in examined children and adolescents aged 10-18 years. These levels are too low, as they account for 38% daily calcium allowance recommended by WHO/FAO for this age group, amounting to 1300 mg/day/person.
