The rate of obesity across the world has seen a steady increase in the past several decades. This disease can lead to significant harm associated with one’s body functioning and mental health. The potential causes of obesity incorporate social, environmental, and personal factors. This article attempts to cover the correlation between obesity and income level using a linear regression model. Samples were extracted from the National Health and Nutrition Examination Survey about 545 individuals from 2017 to 2020. The dataset was subdivided into four cohorts, which include non-Hispanic White male, non-Hispanic White female, non-Hispanic Black male, and non-Hispanic Black female, respectively, to avoid variables that might confound with the explanatory variable. The study found out that the correlation for White male, White female, and Black female can be either positive, negative, or non-existent, and positive on the other hand for the Black male cohort. However, the study concluded that the linear regression model is ineffective for the topic of analysis as the metrics indicate. The incompatibility of the model can be attributed to the fact that other variables that can possibly confound with the explanatory variable are neglected and not filtered out.

Heart disease remains a global health threat, making rapid identification crucial. Using the Heart Disease Dataset from Kaggle, this research employs a Random Forest model to analyze 13 clinical variables from 1,025 samples. To improve accuracy and address class imbalance, the dataset was split into training and test sets, utilizing methods such as Z-scores, SMOTE, and feature selection. The Random Forest model, which combines multiple decision trees, achieved high performance with an accuracy of 98.54%, identifying key predictors such as chest pain type, maximum heart rate, and thalassemia. Compared to a single decision tree, the Random Forest model reduces overfitting, improves generalization, and increases predictive accuracy. Factors like cholesterol levels, resting blood pressure, and exercise-induced angina were also considered. By averaging results from multiple trees, the model offers reliable and stable predictions, highlighting its potential in clinical settings for early detection and personalized treatment strategies. This study aims to assist healthcare providers in better allocating resources, planning preventive measures, and tailoring treatment plans to individual patients.
