The questionnaire was modeled after the American Behavioral Risk Factor Surveillance System survey2 and gathered information on participants' demographic characteristics, health status, quality of health care, fruit and vegetable consumption, smoking status, level of physical activity, and alcohol consumption. Moreover, it included items addressing respondents' awareness of their cholesterol, blood pressure, diabetes, and cardiovascular disease status. The survey comprised 13 modules, included 51 questions, and required approximately 10 to 15 minutes per interview.
Moscow was selected because there is almost universal residential telephone coverage, results could be used to plan prevention programs for a large portion of the population, and findings would be salient to Ministry of Health officials who reside in Moscow. The Russian National Center for Preventive Medicine conducted the survey as part of its ongoing public health responsibilities, and CDC provided assistance in analyzing the data.
A random sample of 3032 residential telephone numbers was selected. Up to 15 telephone calls were made to interview an adult aged 25 to 64 years in each household, and 1693 interviews were completed (representing 69.1% of those contacted and eligible, or 55.8% of the original sample). Prevalence rates of selected risk factors are shown in Table 1
. The results of the survey indicate that telephones are a feasible way to collect behavioral risk factor data in Moscow, and these data provide valuable information that can be used to plan preventive programs and evaluate their effectiveness.

Response reliability and validity must also be addressed. While complete standardization between methods may be impossible, harmonization of questions, data analysis, and interpretation will be required. Currently, the infrastructure for a national surveillance system is inadequate; most health data are facility based and focus on counting numbers of medical procedures or calculating rates of infectious diseases. Finally, the value of tracking population levels of risk factors for noncommunicable diseases must be demonstrated.
The collaboration between CDC and the Russian National Center for Preventive Medicine has been successful in placing prevention and public health on the national agenda; an important goal in our future collaboration is institutionalizing adequate data collection systems for planning and program evaluation. As a next step toward the goal of establishing a countrywide behavioral risk factor surveillance system, 15 more sites have agreed to collect risk factor prevalence information in 20012002.
