Japan 6
Japan’s starting point 1945 7
Post-war Japan • Tradition of strong commitment to health improvement • Minimal diversion of resources into military • Development of strong economy • Rapid urbanisation • Very late adoption of smoking • Capacity to adopt and adapt new technologies from vanguard countries in all spheres (industry and health care) 8

Post-war communist Europe 13

Major barrier to diffusion of new knowledge 16
Post-war communist Europe • Public health function remained with pre-war focus on infectious disease • Low level expenditure on health care and health technology • High expenditure on military investment • Population health improvement not central political priority • Cultural, scientific and technological isolation (especially in biomedicine) 17

Its not just alcohol. . . • Smoking in men • Availability of primary and secondary prevention approaches and technologies – Statins under-utilised – Very poor control hypertension – Low levels revascularisation procedures • Access to and organisation of good standard medical care – Screening programmes but poor follow-up – Continuity of care following hospitalisation – Inadequate level expertise in primary care 51

Sex differences in life expectancy • European countries vary dramatically in the extent of gender differences in behaviour (healthrelated and other) • Western Europe showing decline in differences • Convergence in behaviours in Western Europe – eg decline in smoking in men, stability or increase in smoking in women • Differences in Eastern Europe persist despite improvements in mortality in many countries 63
Conclusions • Communism and its collapse in Europe illustrates the profound influence of the “social” on health • Diffusion of knowledge and best practice in health care and public health central across borders crucial for population health • Rapidity of improvements a cause for optimism • Russian experience vivid warning that things can go badly wrong • The willingness and ability of governments to prioritise improvements in health care and public health critical • International variation in sex-differences in mortality underlines importance of (less tractable) cultural factors in determining health 64
