|Title:||Weight, physical activity, and smoking as determinants of insulinemia in adolescents|
|Author:||Gonzalez-Lopez A, J.L.|
|Abstract:||A voltammetric characterization of a dental amalgam and simple solid metal amalgams and their applications for detecting low concentrations of Cu(II) ions in solution is presented. Dental amalgams display a series of oxidation peaks characteristic of the different metal phases present. A reaction between deposited copper and ?2-Sn7-8Hg phase which transforms into a ??-Cu6Sn5 phase has been proposed to explain the well defined oxidation peaks in the potential range of-0.2 to 0.1 V vs. SCE. Dental amalgams were not found suitable for detecting Cu(II) ions in solution, due to the interference between the ?2-Sn7-8Hg oxidation peak and the copper stripping peak. Instead of a dental amalgam a silver amalgam, i.e, Ag-Hg, is recommended as a better option for detecting Cu(II) ions in solution at low concentrations. It yields a well defined oxidation peaks for copper stripping without having interfering oxidation peaks for the amalgam phase oxidation.

It is known that insulinemia is the result of the interaction among several factors, such as weight, body fat pattern distribution, and physical activity as well as ethnicity. There is little information regarding this question among Mexican adolescents. The association among fasting insulin levels, weight, fat distribution, physical activity, and cigarette smoking was studied in Mexican adolescents. Methods. Cross-sectional data were collected from 352 Mexican adolescents aged 14-19 years (response rate 41.5%). Fasting insulin levels were measured by microparticle enzyme immunoassay; body mass index (BMI), waist-to-hip ratio (WHR), and waist circumference (WC) were determined using standardized techniques, while physical activity was determined by 7-day Stanford physical activity inventory. Cigarette smoking was defined as number of cigarettes/year. Results. Increased BMI and waist circumference, low physical activity, younger age, and non-smoking were associated with high insulin levels. Non-smokers had higher fasting insulin levels compared to smokers (57.8 pmol 1.84 vs. 49.7 pmol/L 2.8; p = 0.034). However, adjusted odds ratio (OR) between insulin and smoking status was not significant. Multivariate analysis showed the following: insulin increased 1.06 pmol/L for each unit of change in BMI; increased 1.02 pmol/L for each unit of change in waist circumference; increased 1.16 pmol/L for non-smoking, and decreased 1.07 pmol/L for each 250 kcal/day of energy expenditure. Conclusions. Our results support the concept that Mexican adolescents who are overweight have abdominal fat distribution and physical inactivity, and significant hyperinsulinemia. The relationship between smoking and lower insulinemia found in this research warrants further study. Copyright " 2001 IMSS.
