“…Although mean Ca intakes were signi®cantly higher in males than in females, intakes for both sexes were above the current UK RNI [9]. A meta-analysis has suggested that, in populations with relatively high Ca intakes, the positive e ects on bone status may be dicult to observe [31]. It is possible that the reported Ca intakes were above a threshold level to exert an e ect on bone.…”

“…Con¯icting results have been published concerning the effect of calcium intake on bone density, but a recent metanalysis (Welten et al, 1995) suggested that calcium intake can at least partially explain the bone density variability. Moreover, an analysis of studies evaluating the effect of exercise on bone density (Specker, 1996) showed that, at least for spine bone mineral density, a calcium intake of more than 1000 mgaday is necessary before exercise can exert a positive effect on bones.…”

Objectives: Evaluation of the impact of a coronary heart disease prevention program on calcium, magnesium, phosphorus and vitamin D dietary intake in respect of recommended daily allowances in a large Italian rural population. Design: Retrospective analysis of the Brisighella Study dietary data. The Brisighella Study started in 1972 as a longitudinal study on atherosclerosis risk factors. Setting: Brisighella, a rural North Italian village. Subjects: The Brisighella population's dietary habits were monitored from 1980 every 4 h through a dietary record sheet. 1350 constantly tested subjects were subdivided according to NHI Consensus Conference on Calcium RDA. Intervention: In 1986, the studied subjects were invited to reduce their consumption of animal fats and cholesterol through a Nutrition Educational Program (NEP). Results: Before NEP, calcium intake was low in each sex and age category: 20 ± 40% of the populatioin had a daily intake`550 mg. In 1988, among the 1350 subjects who constantly completed the questionnaire (M 651, F 699), the mean calcium intake signi®cantly rose in all age categories: M 1003 (25 ± 65 y) and 877 ( b 65) mga24 h (P`0.001 vs 1984); F 923 (25 ± 50), 860 (51 ± 65) and 767 ( b 65) mga24 h (P`0.05). In 1992, 3 y after the NEP conclusion, calcium intake dropped in each sex and age category. The NEP in¯uenced vitamin D, phosphorus and magnesium intakes less. Conclusions: A collective NEP aimed at lowering saturated fats and cholesterol intakes, improves the calcium intake; in order to maintain their ef®cacy on nutritional habit changes, these programs must become an ongoing item.

“…One approach of osteoporosis prevention is to increase the peak bone mass (Matkovic, 1992), which is assumed to occur around age 30 y (Recker et al, 1992). Dietary patterns are thought to in¯uence peak bone mass; particularly high intakes of calcium have been suggested to increase peak bone mass (Cummings et al, 1985;Welten et al, 1995). Consequently, the identi®cation of teenagers who are likely to maintain a low calcium intake in adulthood could be valuable in the development of preventive strategies against osteoporosis.…”

Objectives: Because of growing interest in the potential role of calcium in preventive pediatric strategies against osteoporosis, the longitudinal development and tracking of calcium and dairy intake from adolescence into adulthood was addressed. Design: In the Amsterdam Growth and Health Study, a group of 84 males and 98 females were followed over a 15 y period from age 13±27 y. The calcium and dairy intake was assessed six times by a cross-check dietary history method. To assess tracking, two traditional approaches, interperiod correlation coef®cients and percent of subjects who remained in the same quartile of calcium intake over time, and a new approach based on generalized estimating equations were used. Results: The mean calcium intake was relatively high and increased over time (30%). The tracking of calcium and dairy intake from adolescence into adulthood was moderate in both sexes (for example the correlation for calcium was 0.43 in males and 0.38 in females). Conclusions: The predictability of calcium intake over time does not seem to be suf®ciently strong to identify teenagers who are likely to maintain an inadequate calcium intake in adulthood. Therefore, the identi®cation and treatment of subjects with a low calcium intake cannot be limited to the teenage period but should be extended into adulthood.
