People of high socioeconomic status experienced cardiovascular benefits, but their lower socioeconomic peers did not, a study showed
IT was the peculiar genius of Paul Celan to be able to strip language of its normal socioeconomic occasions without cutting the lines that lead language to the heart. For all the celebrated difficulty of Celan's poems - dense constellations of morphemes, word elements packed like molecules - they are hard only when you try to think about them. At first touch (what William Carlos Williams called, in a noble phrase, the poem's ''intention to impress'') Celan's poems come to us from a warm sense of life, of paying attention and taking care.
At the start of the study, consistent breakfast eaters had an average body mass index of 21.7, intermittent eaters 22.5, and those who never had breakfast 23.4. Over the next five years, B.M.I. increased in exactly the same pattern. The relationship persisted even after controlling for age, sex, race, socioeconomic status, smoking and concerns about diet and weight.
The authors acknowledge that the study depends on self-reports of weight and eating habits, which are not always reliable, and that even though they controlled for many variables, the study was observational, showing only an association between breakfast eating habits and body mass, not a causal relationship.

College Board officials said the difficulties arise more from socioeconomic than from ethnic differences.
