Central obesity is a state of the body characterized by the accumulation of excess fat in the abdominal area and is a component of the metabolic syndrome and plays an important role in the pathogenesis of cardiovascular disease and cancer. The main causes of central obesity are the wrong diet such as a diet high in fat and carbohydrates and low in fiber. The purpose of this study was to analyze carbohydrate and fat intake in young adults with central obesity. This research was an analytical study with a cross-sectional approach. The Sampling techniques used the purposive sampling method with a sample of 66 people consisting of 33 central obese people and 33 central non-obese people. The results of this study showed that the average consumption of carbohydrates in a day on central obesity is higher (341,74 g/ day) than the consumption of carbohydrates in non-central obesity (263,26 g/day) and the average consumption of fat in a day on central obesity is higher (167.2 g/day) than the consumption of fats of non-central obesity (100,3 g/day). There was a significant difference in carbohydrate intake and fat intake between the group of young adults with central obesity and non-central obesity (p=0.000).
Background: Central obesity stands for the corner-stone of cardio-metabolic health, while nitric oxide (NO) is a major regulator of cardiovascular function. To day, the correlation between serum NO metabolites nitrate/nitrite and the obesity components in young adults remains elusive. Thus, this current study was conducted to know the correlation between serum NO metabolites levels and body fat percentage, waist circumference (WC) as well as body mass index (BMI) in young adults with central obesity.Materials and Methods: A cross-sectional study was conducted in Riau, Indonesia, involving 79 young adults aged 18-25 years, composing of 39 and 40 subjects with and without central obesity, respectively. Anthropometric measurements were performed to assess WC and BMI. Body fat percentage was measured using bioelectrical impedance analysis and serum NO metabolites levels were assessed using Griess methods.Results: Levels of serum NO metabolites were significant higher in the subjects with central obesity (168.41±12.64 μmol/L) than that of normal subjects (70.57±44.99 μmol/L, p<0.001), but the levels were no significant different between male and female subjects. Serum NO metabolites levels were strongly correlated with total body fat (r=0.618, p<0.001), visceral fat (r=0.733, p<0.001), subcutaneous fat (r=0.547, p<0.001), WC (r=0.717, p<0.001) and BMI (r=0.788, p<0.001).Conclusions: For young adults in Riau, Indonesia, levels of serum NO metabolites are higher in the central obesity group than that of the normal. In this population, body fat percentage, waist circumference and body mass index are correlated with serum nitric oxide metabolites levels.Keywords: nitric oxide, body fat percentage, young adults, central obesity
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
