The Function of Telomeres in Obesity Term Paper
The Function of Telomeres in Obesity - Term Paper ExampleThe investigators carried out a case-control study involving 793 children, obese (above the 97th percentile for weight) and non-overweight (below the ninetieth percentile for weight). Their peripheral blood samples were taken and leukocyte DNA extracted, from which measurements of telomere lengthening was through using PCR. Statistical digest showed that mean leukocyte telomere length in the obese group was significantly lower than in the non-overweight group, equating to to the highest degree a 24% decrease. No statistical differences were lay out across gender, age, blood pressure or make out cholesterol levels, however, telomere length was inversely related to height and weight. The investigators concluded that telomeres of obese children are significantly shorter than those of non-obese children of same age, and therefore obese children have a biological age that is significantly higher than their actual chronological age an alarming conclusion which stresses the importance of reducing fleshiness in order to reduce the adventure of future diseases. Buxton et al (2011) cited a number of published articles. More than one of the cited roots demonstrated how fleshiness in various ways by a waistline-hip ratio in women, for example - was linked to shorter telomere length. Among the references, the paper that was more or less critical to the study objectives of Buxton et al (2011) was the study by Farzaneh-Far et al (2010). This is because it was the largest, most robust, and most usual study, with the highest standards of question methodology.... Buxton et al (2011) cited a number of published articles. More than one of the cited papers demonstrated how obesity in various ways by waist-hip ratio in women, for example - was linked to shorter telomere length. Among the references, the paper that was most critical to the study objectives of Buxton et al (2011) was the study by Farzaneh-Far et a l (2010). This is because it was the largest, most robust, and most popular study, with the highest standards of research methodology. This was a prospective cohort study, the most reliable study design, involving 608 participants over 5 years. Participants were patients with cardiovascular disease. The investigators found that over 5 years, 45% of these patients developed telomere shortening, 32% maintained the same telomere length, and 23% lengthened telomeres. separatist predictors of telomere shortening in cardiovascular disease patients included older age, male sex, and abdominal obesity (higher waist to hip ratio). Study participants with the longest telomeres experienced the greatest amount of shortening, while those with shorter telomeres maintained or increase their length. This suggested that there whitethorn be negative feedback regulation of leukocyte telomere length in humans. The shortening of telomeres was postulated to be done by the enzyme telomerase. In contrast w ith prior cross-sectional studies, the authors found no significant associations between telomere flying and blood pressure, insulin resistance, smoking, body mass index, or physical activity. It was recognized that many genetic and environmental stressors may have acted as confounders to influence
