Nutrient intake, body mass index, and ethnographic factors associated with obesity in young adults age 20--39 years old: 1999--2000 National Health and Nutrition Examination Survey

Obesity has become more prevalent according to the NHANES 1999–2000. Obesity is a risk factor for several chronic diseases, thus it is vital to recognize the different factors that may contribute to obesity in the young adult 20–39 years old. The objective of the study was to identify factors different in young adult obesity status. Data were obtained from the NHANES 1999–2000. Factors associated with the differences in obesity were compared by BMI categories. The BMI categories were divided into normal, overweight, and obese. The statistical analysis used was chi-square and regression using SUDDAN procedures. The race/ethnicity, gender, and age variables were all significantly associated with the BMI categories. Obesity and overweight continues to be a growing concern in the minority populations. Non-Hispanic blacks continue to increase in obesity, while Mexican Americans increase in overweight.; Obesity was more prevalent in females than males. As age increased, obesity increased. Other variables associated with BMI categories included waist circumference and fiber. The waist circumferences compared with BMI categories were significant. Young adults in overweight and obese BMI categories had greater waist circumference. Fiber intake of obese young adults was lower than the intake in the normal BMI category; although, the overweight category had the highest fiber intake. This data may be an indication that a diet with deficits in fruits, vegetables, and whole grains is related to obesity.
