摘要: The baseline observations in the Puerto Rico Heart Health Program during 1965-1968 involved blood pressure determinations, other measurements, and a 24-hour dietary recall 7932 men aged 45-64 years. This extensive data base provided an opportunity to test hypothesis that low calcium intake is related increased level. Among without coronary heart disease not taking antihypertensive medication, there was inverse relationship between milk consumption definite hypertension urban Rican older rural men. When from all age area groups had been averaged, twofold increase found subgroups who drank no compared those consumed over 1 quart of day. Similar trends were when estimate total food, principally milk, used. With multivariate analysis while known correlates simultaneously considered, independent effect persisted pressure. These results appeared confirm association hypertension. It still possible ascribe causal pressure, however, due intricate network covarying food intakes, factors absorption or lack calcium, role unmeasured social cultural may play observed relations.
