A City Guide To Minggang for Both SES and behaviour appear to independently predict health. What is perhaps worth considering here is why people in the lower socio-economic groups engage in more health compromising behaviours. It does not appear to be the result of lack of knowledge Narevic and Schoenberg Rather, it may be a deliberate choice based on a calculation of the costs and benefits of such behaviours. Work by Graham , for example, suggested that working-class women smokers were well aware of the adverse health consequences of smoking, but continued to do so as it helped them cope with the day-to-day stresses of running a family with low economic resources. The type of health-behaviour choices we make, and in some cases the availability of such choices, may be constrained by the social context in which we live. Of particular interest is that socio-economic factors may, on occasion, actually overwhelm the effects of individual behaviour. An example of this can be found in the work of Hein et al. A City Guide To Minggang 2016.
