Background: Early childhood media exposure is associated with obesity and multiple adverse health conditions. The aims of this study were to assess parental attitudes toward childhood television (TV) viewing in a low-income population and examine the extent to which child BMI, child/parent demographics, and household media environment are associated with adherence to American Academy of Pediatrics (AAP) guidelines for screen time.Methods: This was a cross-sectional survey study of 314 parents of children ages 0-5 years surveyed in English or Spanish by selfadministered questionnaire at a Special Supplemental Nutrition Program for Women, Infants and Children (WIC) clinic in Oregon.Results: In this majority Latino sample (73%), half (53%) of the children met AAP guidelines on screen time limits, 56% met AAP guidelines for no TV in the child's bedroom, and 29% met both. Children were more likely to meet AAP guidelines when there were <2 TVs in the home, there was no TV during dinner, or their parents spent less time viewing electronic media. Parents who spent less time viewing electronic media were more likely to report believing that TV provides little value or usefulness.Conclusions: In this low-income, predominantly Latino population attending WIC, parent media-viewing and household media environment are strongly associated with child screen time. Programs aimed at reducing child screen time may benefit from interventions that address parental viewing habits.

The present study shows that a high-risk screening strategy for IGT targeted solely toward subjects with obesity and/or heredity background of diabetes will fail to detect the majority of subjects with IGT in the general population. The new concept of IFG may not replace the concept of IGT as a risk marker for worsening to diabetes.

Introduction We evaluated the potential utility of a new prototype noninvasive muscle oxygenation (MOx) measurement for the identification of shock severity in a population of patients admitted to the trauma resuscitation rooms of a Level I regional trauma center. The goal of this project was to correlate MOx with shock severity as defined by standard measures of shock: systolic blood pressure, heart rate, and lactate. Methods Optical spectra were collected from subjects by placement of a custom-designed optical probe over the first dorsal interosseous muscles on the back of the hand. Spectra were acquired from trauma patients as soon as possible upon admission to the trauma resuscitation room. Patients with any injury were eligible for study. MOx was determined from the collected optical spectra with a multi-wavelength analysis that used both visible and near-infrared regions of light. Shock severity was determined in each patient by a scoring system based on combined degrees of hypotension, tachycardia, and lactate. MOx values of patients in each shock severity group (mild, moderate, and severe) were compared using two-sample t-tests. Results In 17 healthy control patients, the mean MOx value was 91.0 ± 5.5%. A total of 69 trauma patients were studied. Patients classified as having mild shock had a mean MOx of 62.5 ± 26.2% (n = 33), those classified as in moderate shock had a mean MOx of 56.9 ± 26.9% (n = 25) and those classified as in severe shock had a MOx of 31.0 ± 17.1% (n = 11). Mean MOx for each of these groups was statistically different from the healthy control group (p<0.05). Receiver operating characteristic (ROC) analyses show that MOx and shock index (heart rate/systolic blood pressure) identified shock similarly well (area under the curves (AUC) = 0.857 and 0.828, respectively). However, MOx identified mild shock better than shock index in the same group of patients (AUC = 0.782 and 0.671, respectively). Conclusions The results obtained from this pilot study indicate that MOx correlates with shock severity in a population of trauma patients. Noninvasive and continuous MOx holds promise to aid in patient triage and to evaluate patient condition throughout the course of resuscitation.
