KHOU-TV (CBS) Ch. 11 Houston TX (Internet / TV) 07/16/06 Social standing, level of education and income have a direct effect on men’s chances of dying from smoking, according to an international study to be released Sunday. Karl Eschbach, associate professor at the Center for Population Health & Health Disparities at the University of Texas Medical Branch, said Thursday that the study certainly reinforces the correlation between lower socioeconomic status and health problems in the United States. “Perhaps it may even overstate the smoking factor,” said Eschbach. “What we’ve seen is that the health differences (among the socially disadvantaged) reflect a response to other social stresses.   “When you go to bed at the end of the day, are you optimistic or pessimistic based on what is involved in your life? We know anxiety and depression kill, and that these factors are more prevalent among the disadvantaged. Smoking is only part of that.”
