Most individuals would believe that the cause of diabetes, heart disease, or other chronic illnesses is due to their own unhealthy lifestyle decisions. For example, most people would think that due to smoking, stress and lack of exercise, the risk of suffering from these diseases is higher. However, Barker has a different view. As DJP Barker states in his article Fetal and Infant Origins of Adult Disease Hypothesis that adaptations made by the fetus when undernourished rather than adaptations made in adulthood and those made during early development tend to have a permanent effect on the structure and function of the body. (Barker, 2001). He hypothesizes that low birth weight is a contributing factor to the development of coronary heart disease in adulthood, but he neglected the fact that sociological factors during adult life may also trigger the development of coronary heart disease. Although the fetal origins hypothesis has used a biological explanation for the development of coronary heart disease, it fails to recognize the sociological factors of coronary heart disease. One's position on the socioeconomic gradient contributes to coronary heart disease risk. According to the Barker Hypothesis, it explains how maternal exposure and metabolism can affect the health of the fetus. It hypothesizes that the environment the mother is exposed to before and during childbirth may have an effect on the health of the fetus as it ages. As we know, the woman is responsible for reproduction, so the health of the mother can have a direct effect on the fetus. If the mother is undernourished, this will potentially send a signal to the fetus that the environment is about to enter into a harsh relationship and that the ...... middle of paper ...... sexual relationship with cardiovascular diseases. Overall, the results show that it is better to increase or stabilize income, as this would decrease the risk of cardiovascular disease. However, Johnson's hypothesis only used socioeconomic status in relation to income for coronary heart disease, but it does not explain how coronary heart disease would be measured if a person has no income, for example like children and adolescents, then what would be their risk of coronary heart disease. illness would be a measure. Would this then be a measure based on parental income? Since children are cared for by their parents, whatever the parent is exposed to will have an indirect relationship with the children. Follow-up studies should be conducted on how a person's social gradient changes over the course of their life in relation to cardiovascular disease..
