urban districts. Personal telephone ownership in 1991 was estimated at 92 telephones per

Moscow Health Profile questionnaire was based on items drawn directly from existing
sources: the California Alameda County Study on Health and Ways of Living (Berkman and
Breslow, 1983), and the U.S. NCHS Health Interview Survey (Adams, 1991). The Alameda
Physical Health Profile was developed as a multidimensional, non-disease-specific,
self-perceived measure of general physical health for community-based samples, extensively
described and applied in community cohort studies (Belloc et al., 1971). |
