Abstract

Objective: To assess the predictive value of calcium intake from milk products and its effect of this on the total contribution of food calcium.

Design: Cross-sectional study.

Setting: Urban and rural health centres in Spain.

Participants: Patients aged 20 or over who attended for consultation for whatever reason in the time-period set. Criterion for exclusion: terminal illness. 1546 questionnaires were included in the study.

Main measurements: Consumption of calcium from milk products and from other sources.

Results: The intake of milk products accounted for 66.8% of the total intake of calcium (0%-93%). The consumption of < or =2 rations of milk products per day supposed a total calcium intake of under 1000 mg/day; of >3 rations, a total intake of 1000-1500 mg/day; and of >4 rations, 1500 mg/day. In subjects with low milk product intake (< or =2 rations per day), the predictive value of this for total calcium was low (10%-30%); and in those with >4 rations, its predictive value was 70%.

Conclusions: Calculation of the total intake of calcium in milk products is useful in the consultation, but undervalues the real contribution, as it takes no notice of calcium from other food sources. Only the intake of >4 rations of milk products a day is sufficiently predictive.

Objetivo: Valorar el poder predictivo de la ingesta de calcio a través de los lácteos y la influencia que ésta tiene sobre el aporte total de calcio alimentario.

Diseño: Estudio tranversal.

Emplazamiento: Centros de atención primaria urbanos y rurales en España.

Participantes: Individuos de edad 20 ≥ años que acudían a la consulta por cualquier motivo dentro del período establecido. Criterio de exclusión: enfermedad terminal. Se incluyen 1.546 encuestas.

Mediciones principales: Consumo de raciones de calcio lácteo y no lácteo.

Resultados: La ingesta de lácteos representó un 66,8% de la ingesta total de calico (rango, 0–93%). El consumo de ≤ 2 raciones de lácteos al día supuso una ingesta total de calcio inferior a 1.000 mg/día; el consume de > 3 raciones, una ingesta global de 1.000–1.500 mg/día, y > 4 raciones, un total de 1.500 mg/día. En los sujetos con una baja ingesta de lácteos (≤ 2 raciones lácteos/día), el valor predictivo de éstos con respecto al calcio total era bajo (10–30%) y si consumían >4 raciones, era del 70%

Conclusiones: El cálculo de la ingesta total de calcio a través del calcio lácteo es útil en la consulta pero infravalora el aporte real al no tener en cuenta alimentos no lácteos. Sólo la ingesta de >4 raciones de lácteos al día resulta bastante predictiva.
