We would expect no link between candidate genes for asthma and socioeconomic status since genes are allocated in a randomized way at conception according 34 5 Descriptive Epidemiology in Public Health Gene variants Socioeconomic Status (SES) Asthma to Mendel’s laws. Among children with asthma you would expect an association between these genetic factors and SES according to this diagram. Good social conditions may lead to asthma as well as certain genetic factors; therefore these two variables become associated in children with asthma (and to a lesser extent in children without asthma).
We furthermore notice that if we control bronchial reaction we open another back-door path via air pollution to sex and asthma. We call bronchial reaction a collider in the path between air pollution and sex. Since both arrows point toward bronchial reaction we would establish a link between air pollution and sex since they are both causes of this bronchial reaction. A collider can therefore lead to a misleading result if it is included improperly in the analysis. The DAG tells us we should not just include all potential confounders in our analysis.
Chapter 5 Descriptive Epidemiology in Public Health Data on incidence and prevalence of diseases are needed to characterize the health of a population. Public health organizations oversee these efforts. The public health staff need to have a community diagnosis to set priorities. The key to this diagnosis is incidence and prevalence of diseases and the occurrence of risk factors in the population. We need to monitor incidence data over time to identify changes in their occurrence. If the incidence is increasing and we know the causes and know how to avoid them, prevention strategies may be applied.
