The relationship among inflammatory markers, physical fitness, and body mass index to cardiovascular disease
Turner, Marcia Elizabeth
10,291 participants, aged 20 to 85 years of age, available from the 1999 through 2002 NHANES databases participated in this study. Only 8,485 (82%) of these participants were included in the data analysis. Participants who were pregnant (n = 603), not examined at a mobile examination center (n = 820), or had missing values for height (n = 164) and/or weight (n = 125) were eliminated. Individuals were classified into four groups (underweight, normal, overweight and obese) based on body mass index (BMI). Variables measured in the study included body mass index, physical fitness, dietary folic acid, c-reactive protein, homocysteine, folate, serum total cholesterol, serum triglycerides, HDL-C, and glucose. All data was collected at Mobile Examination Centers (MEC). The results of the present study showed that being overweight and obese were associated with a poor serum lipid profile, higher serum glucose levels, lower participation in physical activity and a lower physical fitness level. Being overweight and obese was also associated with higher serum levels of inflammatory markers for cardiovascular disease (CVD). Overweight and obese individuals are also being diagnosed with coronary heart disease (CHD) at a younger age.
