Introduction: Obesity in childhood is a major cause for developing cardiovascular diseases (CVD) at adulthood. The present study was a cross-sectional research aimed to examine the relationship between childhood obesity and dietary pattern with CVD in patients (n=100) from Tangail City, Bangladesh. Methods: Dietary patterns, laboratory tests, demographic, and anthropometric interrelated data were measured in patients with stroke and heart attack from five hospitals. The research also used 24-hour recall method and a food frequency questionnaire for assessing daily energy and macronutrient intakes. Results: Weight (p=0.004), body mass index (BMI) (p=0.001), mid-upper arm circumference (MUAC) (p=0.009), and waist circumference (WC) (p=0.030) was significantly different between males and females whereas lipid profile was not significantly different between genders. There were no significant associations between intakes of red meat, salt, fast food, fish, egg, nuts and seeds with heart attack and stroke. On the contrary, there were significant associations between fried food intake with heart attack and stroke (p=0.080 and p=0.020). The results indicated that there was a significant relationship between carbohydrate (p=0.001), protein (p=0.001), and fat (p=0.001) intakes with the total energy intake of respondents. The findings also showed that there was a significant relationship between carbohydrate (p=0.003), protein (p=0.001), and fat (p=0.001) intakes with body mass index of the respondents. Conclusion: CVD diagnosis in adult patients was found to be associated with fried food intake but not with childhood obesity.
