Russian immigrant cardiovascular risk assessment.

Immigration from the former Soviet Union has been increasing. In 1990, there were 454,000 Russian immigrants living in the United States. Lifestyle habits prevalent in Russia, including smoking, alcoholism, and little preventive health, are compelling medical and economic reasons to understand the health status of this population. This study identified a cohort of Russian-born subjects living in Denver to characterize their cardiovascular risk profile. Using a risk assessment questionnaire, 204 Russian immigrants were screened. Seventy-one percent had Medicaid insurance; 14 percent were medically indigent. Those aged 55 to 64 years had a higher prevalence of hyperlipidemia (p < 0.04) and hypertension (p < 0.03) than U.S. counterparts; those age 20 to 34 and 65 to 74 years had a higher prevalence of hypertension (p < 0.00001). Almost half of the participants had two or more cardiac risk factors. Cardiac risk factor identification and intervention programs may help to reduce the health care costs for these patients.

As-needed medication use in asthma usage patterns and patient characteristics.

Daily inhaled bronchodilator medication usage was recorded using an electronic device and airway obstruction by daily peak flow measurement. The demographic, clinical, and psychological characteristics of the subjects were noted. Subjects were allocated to as-needed (prn) medication usage groups according to the mean number of inhaler activations on days with zero, moderate, and severe airway obstruction. Segregation into arbitrary and nonarbitrary use, and into overuse, appropriate use, and underuse resulted in six usage groups. Appropriate use was observed in only 10 of 39 subjects. The major psychological variable to differ among groups was the MMPI variable Pt, representing general anxiety. Arbitrary users had a significantly higher mean score than nonarbitrary users. The variable Specific Internal Awareness, representing a perceived difficulty in recognizing the premonitory symptoms of an asthma attack, also differed among the usage groups, with arbitrary users having the lowest scores. These findings raise the possibility that reliance on an objective measurement of airway obstruction rather than on subjective symptomatology might enhance compliance with prn medication in some patients.
