Sleep Timing and Insulin Resistance in Adolescents With Obesity

Obesity

This study examines the relationship between sleep timing and insulin resistance in adolescents with obesity. The investigators also aim to develop a physiologically-based mathematical model of adolescent sleep/wake and circadian interactions.

Insulin-sensitive Obesity: Lessons From Longitudinal Data

Insulin Sensitivity/ResistanceObesity

People who are overweight and/or obese are at risk of insulin resistance and type 2 diabetes. However, research has shown that some overweight and/or obese individuals remain insulin-sensitive and metabolically healthy despite their unhealthy body weight. The investigators hypothesise that overweight and/or obese people who were deemed insulin-sensitive in previous studies will maintain their insulin sensitivity and metabolic health over time. The investigators also hypothesise that the preservation of insulin sensitivity will be accompanied by key metabolic health markers.

Diurnal Variability in the Regulation of Beta-cell Function and Insulin Sensitivity in Overweight...

Overweight

The purpose of this research study is to learn more about how our body produces sugar, breaks down fat for fuel, and makes insulin (the major hormone that controls the production of blood sugar and fat breakdown) during a 24-hour day and how body fat and muscle are involved in these processes.

Endothelial Function in Young Hispanic Adults at Risk for Type 2 Diabetes

ObesityInsulin Resistance

Diabetes is a major public health problem. Hispanics/Latinos are known to be at higher risk for type 2 diabetes. The function of the endothelium has played a key role in the understanding of vascular complications in people with diabetes. Endothelial function and vascular reactivity are impaired not only in white adults with type 2 diabetes but also in those at risk for the disease by virtue of having impaired glucose tolerance or parental history of type 2 diabetes. Whether this finding is applicable to hispanics is not known. The investigators plan to assess the endothelial function and vascular reactivity in young Hispanic adults at risk of developing type 2 diabetes by virtue of being obese and belonging to a minority population.

Assessing Insulin Sensitivity and Diabetes Risk in Childhood Cancer Survivors Treated With Abdominal...

Childhood Cancer Survivors Treated With Abdominal Radiation

The purpose of this study is to better understand the risk factors and causes of diabetes in people who received radiation to the abdomen as children. The investigators hope this information will allow them to improve how they screen people at risk for diabetes and how they treat patients in the future.

Impact of INsulin Sensitivity on Cardiovascular Risk Markers During 10-20 Years of FOllow up

Diabetes MellitusHypertension2 more

The purpose of this study is to identify risk factors for insulin resistance and to investigate the influence of insulin sensitivity on development of cardiovascular risk markers like blood pressure, heart rate, body build (weight, BMI, waist-hip ratio, skinfold thickness), reduced insulin sensitivity, diabetes mellitus, dyslipidaemia, and sympathoadrenal activity or manifest cardiovascular disease among young men during 10-20 years.

Gestational Metabolic Abnormalities and Maternal and Infant Nutrition and Health

Gestational DiabetesHyperglycemia2 more

Childhood obesity is on the rise and is a major risk factor for type 2 diabetes later in life. Recent evidence indicates that abnormalities that increase risk for diabetes may be initiated early in infancy. Since the offspring of women with diabetes have an increased long-term risk for obesity and type 2 diabetes, the impact of maternal metabolic abnormalities on early nutrition and infant metabolic trajectories is of considerable interest. The purpose of the study is to investigate the impact of maternal nutrition and metabolic abnormalities in pregnancy on human milk and subsequently on infant health over the first year of life.

Vitamin D Deficiency in Obese Adolescent Girls and Influence of Vitamin D on Insulin Secretion and...

Vitamin D DeficiencyObesity1 more

Sub-clinical vitamin D deficiency is a commonly unrecognized disorder in obese adolescents. The investigators hypothesize vitamin D deficiency will be highly prevalent in obese adolescents and those who are vitamin D deficient will be more insulin resistant.
