Russian President on Demographic Situation in Russia (Address to Russian Parliament, May 10, 2006) n n n Demographic problem is "the most urgent problem of modern Russia" Demographic situation is "critical" "We talked at lot on this topic but did little. " Government is "too slow with unacceptable bureaucracy in resolving the problem" Suggested 10+ year program with three priorities: -- to decrease mortality -- effective migration policy -- to increase fertility
Russian President on How to Decrease Mortality (Address to Russian Parliament, May 10, 2006) n n n Program to prevent traffic accidents and improve road safety (high penalties for drunk driving) To eradicate production and import of alcohol surrogates (poisoned alcohol) National Project "Health" focused on prevention and treatment of cardiovascular diseases, and other major causes of death. Smoking ban in public places High taxes on hard liquors
Age Profiles of Mortality from Accidental Poisoning by Alcohol Data from Russian Vital Statistics Males Females
Снижение качества алкоголя во время рыночных реформ n n In 1992 state monopoly on alcohol sales was abolished Self-production of alcohol became not profitable but over 20% of alcohol sales included technical alcohol Sample control tests showed that proportion of below quality standards alcohol was 5. 6% in 1992 and 30. 4% in 1994 Imported alcohol had even lower quality: 67. 2% below quality standards
Суррогаты алкоголя n n n Alcohol surrogates – non-food liquids containing ethanol (polishing liquids, perfume, pharmaceutical tinctures, etc. ) Alcohol surrogates are cheap, so they are attractive to poor persons. May be the only source of ethanol for impoverished persons. 47% of men who used surrogates were unemployed. Only 13% of men not used surrogates were unemployed

Ethnic Differentials in Mortality
Based on the Study of Ethnic Differentials in Adult Mortality in Kyrgyzstan Michel Guillot (PI), University of Wisconsin-Madison Natalia Gavrilova, University of Chicago Tetyana Pudrovska, University of Wisconsin-Madison Demography, 2011, 48(3): 1081 -1104
Background on Kyrgyzstan n n Former Soviet republic; became independent in 1991 Population: 5. 2 million (2006) Experienced a severe economic depression after break-up of Soviet Union GNI per capita = 440 USD; 28 th poorest country in the world (2005) 48% of population below national poverty line (2001)
2008 Workshop, Bishkek
Ethnic Groups in Kyrgyzstan n Native Central Asian groups: Kazakh, Kyrgyz, Tajik, Turkmen, Uzbek (Sunni Muslims) Slavs: Russian, Ukrainian, Bielorussian Kyrgyzstan, 1999 census: Central Asians: 79% of pop. (Kyrgyz 65%) n Slavs: 14% of pop. (Russian 12%) n
Recorded trends in adult mortality (20 -60 years)
Mortality paradox? n Soviet period: Russians/Slavs occupied dominant positions in the socio-economic structure of Central Asian societies (Kahn 1993)
Mortality paradox? n n Slavic females more educated than Central Asian females (1989 and 1999 censuses) Slavic males: educational advantage not so clear – varies by age (1989 and 1999 censuses) Slavic households less poor than Central Asians (1993 World Bank poverty survey) Infant mortality lower among Slavs (Soviet and post-Soviet period)

IMR by ethnicity, 1958 -2003, Kyrgyzstan
Data n Unpublished population and death tabulations since 1959 n n n collected from local archives Individual census records – 1999 Individual death records – 1998 -1999 n obtained from national statistical office
Possible explanations for mortality paradox n n n Data artifacts Migration effects (esp. 1989 -99) Cultural effects
Data artifacts? n Could the lower recorded mortality among Central Asian adults be due to lower data quality among them (coverage of deaths, age misreporting)?
Migration effects? n n 1/3 of Russian population has left Kyrgyzstan since 1991 Could the increased disparity between Russian and Kyrgyz adult mortality be due to selective migration (healthy migrant effect)?
Cultural effects? n Culture may affect mortality in various ways: individual health and lifestyle behaviors (e. g. , diet, smoking, alcohol, use of preventive care) à family structure and social networks (denser social networks may produce lower stress levels and better health) à n Could different cultural practices among Slavs and Central Asians explain the observed mortality differentials?
Data artifacts? n Intercensal estimates of death registration coverage above age 60 (Guillot, 2004): 90+ % as early as 1959 in urban areas n coverage in rural areas was low initially (~50%) but caught up with urban areas in 1980 s n Total population: 92% for 1989 -99 period n n Adult deaths (20 -59) usually better reported than deaths 60+

Multivariate analysis n n n n Do ethnic mortality differentials at adult ages remain once we account for differences in education and urban/rural residence? Negative binomial regression Dependent variable: deaths from all causes; deaths by major cause (7) Explanatory variables: exposure, dummy variables for age, ethnicity, urban/rural residence, education (3 cat. ) Males and Females analyzed separately Model 1: age, ethnicity Model 2: age, ethnicity, education, residence
Males, all causes of death
Risk Ratio Slavs/CA Males
Risk Ratio Slavs/CA Females NS NS
Conclusions n n n Excess mortality among adult Slavs (Soviet and post-Soviet period) is not likely due to data artifacts or migration effects Excess mortality due to important ethnic differences in cause-specific mortality – alcohol and suicide in particular Differences remain unexplained by education or residence
Conclusions n Role of cultural characteristics? Alcohol tied to cultural practices (“culture of alcohol” among Russians; Impact of Islam for Central Asians) n Denser social networks and stronger social support among Central Asian ethnic groups? n
