Final answer:
Coronary heart disease (CHD) affects men and women differently, with men under 64 being at a higher risk. However, the gender difference decreases with age. Factors like age, genetics, and lifestyle choices contribute to the development of CHD. Correlation between hormone replacement therapy (HRT) and lower CHD incidence in women was due to other lifestyle factors, not HRT itself.
Step-by-step explanation:
Coronary heart disease (CHD) affects both men and women, but there are some differences in the incidence between the genders. Generally, men under the age of 64 are more likely to die from CHD compared to women of the same age. However, as people age, the gender difference in incidence decreases.
There are various factors that contribute to the development of CHD, such as age and genetics. Lifestyle factors, such as smoking and diabetes, also increase the risk of CHD. By making healthy lifestyle choices, such as not smoking, exercising regularly, and maintaining a healthy diet, both men and women can reduce their risk of developing CHD.
It is important to note that correlation does not imply causation. For example, studies have shown that women taking hormone replacement therapy (HRT) had a lower incidence of CHD. However, further research revealed that this correlation was due to other lifestyle factors associated with higher socioeconomic status, rather than HRT itself.
