The relationship of social support with the risk of acute cardiovascular disease in an open population among women 25–64 years in Russia / Siberia

   The aim: to study the prevalence of social support (SS) and it’s influence on relative risk of myocardial infarction (MI) and stroke in female population of 25–64 years in Russia.

   Material and methods: under the third screening of the WHO «MONICA-psychosocial» program random representative sample of women aged 25–64 years (n = 870) were surveyed in Novosibirsk. SS were measured according to the methodic of Berkman-Sym test (indices of close contacts (ICC) and social network (SNI)). From 1995 to 2010 women were followed for 16 years for the incidence of MI and stroke.

   Results: the prevalence of low levels of ICC and SNI in women aged 25–64 was 57.1 % and 77.7 %, respectively. Low levels of ICC and SNI associated with poor self-rated health and awareness about the health, adverse behavioral habits, high job strain and family stress. Over a 16 years of study relative risk of MI in women with low ICC was higher in 4.9 times, risk of stroke was higher in 4.1 times than in those with higher levels of ICC. Low SNI increase risk MI incidence in 2.9 times, risk of stroke in 2.7 times (p for all <0.05). Rates of MI and stroke incidence were higher in married women with low ICC and SNI who were being in class «hard manual labor» compared higher SS levels. 

   Conclusions: our findings show high prevalence low levels of ICC and SNI, associated with poor self-rated health and reduced awareness about the health. Low ICC and SNI increase the risk of MI and stroke in female population aged 25–64 years.
