Physical Activity in the Prevention of Type 2 Diabetes: The Finnish Diabetes Prevention Study
Diabetes, 2005
Clinical trials have demonstrated that lifestyle changes can prevent type 2 diabetes, but the importance of leisure-time physical activity (LTPA) is still unclear. We carried out post hoc analyses on the role of LTPA in preventing type 2 diabetes in 487 men and women with impaired glucose tolerance who had completed 12month LTPA questionnaires. The subjects were participants in the Finnish Diabetes Prevention Study, a randomized controlled trial of lifestyle changes including diet, weight loss, and LTPA. There were 107 new cases of diabetes during the 4.1-year follow-up period. Individuals who increased moderate-to-vigorous LTPA or strenuous, structured LTPA the most were 63-65% less likely to develop diabetes. Adjustment for changes in diet and body weight during the study attenuated the association somewhat (upper versus lower third: moderate-to-vigorous LTPA, relative risk 0.51, 95% CI 0.26 -0.97; strenuous, structured LTPA, 0.63, 0.35-1.13). Lowintensity and lifestyle LTPA and walking also conferred benefits, consistent with the finding that the change in total LTPA (upper versus lower third: 0.34, 0.19 -0.62)

Diabetes type 2 is a world wide spread disease with a multifactorial pathogenetic evolution. Various factors like obesity, physical inactivity and poor lifestyle habits contribute to its development. The aim of this study was to verify if in young healthy sedentary male and female there is positive correlation between family history to type 2 diabetes and an increase in body weight and fat mass, or alterations in basal glycemia values. Totally183 male and 237 female healthy sedentary subjects were analysed in 2012, in Italy. They were divided in three groups: FH(+) with first degree family history, FH(++) with second degree family history and FH(-) with no family history. Anthropometrics, body composition and blood parameters were assessed. Male had the highest BMI values (P<0.01). FH(+) and FH(++) had increased waist and hip circumferences and body weight (P<0.005 for men, P<0.0001 for women), body mass index (P< 0.0001 in both sexes), waist-hip ratio (P< 0.05 for me...

The risk of becoming a diabetic for an individual with a positive family history of diabetes increases by two-to fourfold. Aim: To record the anthropometric indices and the physical fitness in individuals with family history of type-2 diabetes mellitus and compare these results with those of controls. Settings and Design: This is a comparative study done in the department of physiology. Materials and Methods: Thirty-two apparently healthy medical students with family history of type-2 Diabetes Mellitus were chosen for the study and matched with equal number of controls. Anthropometric measurements (height, weight, waist circumference, hip circumference, thigh circumference, upper segment and lower segment) were recorded. Body mass index (BMI), waist-hip ratio (WHR), waist-thigh ratio (WTR), and upper to lower segment ratio (US/LS ratio) were calculated. Blood pressure and heart rate were measured. Physical fitness was evaluated using Queen's College step test protocol. Rate Pressure Product (RPP) and Physical Fitness Index (PFI) were calculated before and after exercise. Statistical Analysis: Statistical analysis was done using SPSS software. Results: BMI, WHR, US/LS ratio, and RPP at rest were significantly higher (P < 0.05), whereas WTR, PFI, and RPP after exercise lower (P > 0.05) in cases as compared to controls. Conclusions: It can be concluded that apparently healthy individuals with family history of type-2 diabetes mellitus have higher anthropometric values and lower physical fitness than the controls.
Exercise, genetics and prevention of type 2 diabetes

Type 2 diabetes is one of the fastest growing public health problems in both developed and developing countries. Cardiovascular disease is the most prevalent complication of type 2 diabetes. In the past decade, the associations of physical activity, physical fi tness and changes in the lifestyle with the risk of type 2 diabetes have been assessed by a number of prospective studies and clinical trials. A few studies have also evaluated the joint associations of physical activity, body mass index and glucose levels with the risk of type 2 diabetes. The results based on prospective studies and clinical trials have shown that moderate or high levels of physical activity or physical fi tness and changes in the lifestyle (dietary modifi cation and increase in physical activity) can prevent type 2 diabetes.

Background: This study examined the independent association of objectively measured physical activity on insulin resistance while controlling for confounding variables including: cardiorespiratory fitness, adiposity, sex, age, and smoking status. Methods: Data were obtained from National Health and Nutrition Examination Survey 2003-2004, a cross-sectional observational study conducted by the National Center for Health Statistics of the Centers for Disease Control that uses a stratified, multistage probability design to obtain a nationally representative sample of the U.S. population. The analysis included 402 healthy U.S. adults with valid accelerometer, cardiorespiratory fitness, and fasting plasma glucose and insulin concentrations. After controlling for relevant confounding variables we performed a multiple linear regression to predict homeostatic model of insulin resistance (HOMA-IR) based on average daily minutes of moderate-to-vigorous physical activity (MVPA). Results: In our bivariate models, MVPA, cardiorespiratory fitness and body fat percentage were all significantly correlated with log HOMA-IR. In the complete model including MVPA and relevant confounding variables, there were strong and significant associations between MVPA and log HOMA-IR (β= −0.1607, P=0.004). In contrast the association between cardiorespiratory fitness and log HOMA-IR was not significant. Conclusion: When using an objective measure of physical activity the amount of time engaged in daily physical activity was associated with lower insulin resistance, whereas higher cardiorespiratory fitness was not. These results suggest that the amount of time engaged in physical activity may be an important determinant for improving glucose metabolism.

Association of Physical Activity with Risk of Type 2 Diabetes
Iranian Journal of Public Health, 2011
Physical activity has shown to prevent type diabetes 2. However, the type, intensity and amount of effective physical activity as well as individuals' needs according to level of their risk for type 2 diabetes have not been clarified comprehensively. This study investigated a relation between moderate aerobic physical activity ≥150 minuets/week with decreased risk of type 2 diabetes among obese and non-obese residents of south of Tehran, Iran. Methods: This study, which was a part of the Cardiovascular Risk Factors Survey in Tehran population Lab region, was designed and conducted based on MONICA/WHO project. Totally, 1552 adult inhabitants of 17th district of Tehran were enrolled in this cross-sectional study. Physical activity was assessed by MONICA Optional Study of Physical Activity questionnaire. Diabetes was defined as a history of a prior diagnosis of diabetes or fasting serum glucose ≥126 mg/dl. All data analyses were conducted using SPSS 17 software for Windows Results: In a multivariate model, moderate aerobic physical activity ≥150 minuets/week was significantly associated with decreased risk of type 2 diabetes in all and non-obese subjects [OR= 0.56; 95%CI: 0.35-0.91 and OR= 0.50; 95%CI: 0.26-0.94, respectively]. There was no significant relation between the physical activity and type 2 diabetes risk in obese subjects [OR=0.64; 95%CI: 0.30-1.39]. Conclusion: Moderate aerobic physical activity ≥150 minuets/week was significantly associated with decreased risk of type 2 diabetes in non-obese people and could be an acceptable exercise goal for these individuals. However, obese people should be investigated more to produce a tailored exercise guideline to this population at high risk of type 2 diabetes.
