Social Factors of Health,Figure 3-1 Category of Social factors,The characteristics of Social factors affecting the health,Because of the widespread existence of social factors and the diversity of the causal link (Figure 3-2), it is often in trouble in analyzing the health effects of social factors. The relationship between social factors and health, although not as straightforward as the biological factors, it still has its own regularity.,Three kinds of causal connection,Figure 3-2,Non-specific (impact/influence/effect/affect/infect),Modern society is multi- society multi-factor, multi-metric, multi-level, multi-disciplinary, multi-dimensional society. Different from biological factors, effect of social factors on the health is of non-specific As a social phenomenon, the disease is determined by a variety of factors, it is difficult to fully explain the etiology of a disease in a single, specific social factor.,Pan-impact,one social factor may result in the functional changes of multiple body organs and systems. Although the disease-causing effects or health-promoting effects of some social factors have a more specific target organ or system, their specificity are relative,The reason for the non-specific and pan- impact of social factors,The impact of a number of social factors have obvious overlap, that is, the role of convergence But, in a real life, people contact with the diversity of social factors, each of the social factors shows non-specific effect Due to differences in genetic and acquired growth, every individual has different tolerance with the same type and intensity of stimulation, so that the role of social factors and health effects of disease specificity is not obvious As a source of stress, social factors mainly play a slow role through the gradual accumulation, which makes the of stimulation lack of specificity have reflected the pan impact.,Constancy of the impact,Social factors are always a relatively stable, its impact on health is invisible, slow and persistent. Because of the widespread of social factors in people's real life, combined with a strong social attributes of human, social factors have a long-lasting effect on human beings. Such widespread and persistent are called the constancy of the impact.,Cumulative effect,refers to social factors acting on the human body in a certain period and can form a cumulative response, function damage or health effects to accumulate,Interaction,The effects of a variety of social factors on health are not parallel, but be mutually conditioned The impact of social factors on human health often generate effects based on the interaction This mainly determined by the diversity of its causal relationship Interactions are often manifested as one social factor can directly affect population health, but can also be used as an intermediary of other social factors, or other intermediary role of social factors on health.,Mechanism of social factors influence health,Affecting human health, Social factors play a role primarily through the psychological experience the central link The mechanism of Social factors affecting the health is the perception of social factors were incorporated into the system, through the central nervous system regulation and control, form a psychological refraction, resulting in psychological reactions and behavior, social adaptation and change in physical function,Population,Psychological,Civilization,Environment,Trait,Development,Respone,Social Factors,Perception System,Brain,Other brain areas,Pituitary,Hormone,Immune,Physical disease,Changes in behavior and emotional and mental problems,Hypothalamic,Stimulu,Evaluation,Socioeconomic factors and health,There are two-way functions between health and socioeconomic development.,GDP,Gross domestic product (GDP) refers to the market value of all officially recognized final goods and services produced within a country in a given period. GDP per capita is often considered an indicator of a country's standard of living;,三类经济发展水平国家的居民健康水平,部分国家居民健康指标与经济水平的关系,Economic development brings in the negative effect,Contamination and destroy of circumstance Harmful behavioral life style Smoking, excessive drinking , drug addicts , sexual random ,irregular food, drink and sleeping The social negative events Traffic jam, traffic accident, violent crime Modern social diseases Affluent disease: hypertension, diabetes, coronary heart disease, obesity Civil disease ：air conditioning syndrome, computer syndrome, electronic game epilepsy The social migrant population,THANK YOU !,
