an observational study
Objective This study aimed to investigate total and device-specific screen
viewing (SV) and its determinants in children aged 2 years and below. Design
Cross-sectional study conducted in February 2014. Setting Well-child clinics
in Singapore national polyclinics. Participants Parents of children (Singapore
citizens or permanent residents) aged 2 years and below were enrolled during
routine clinic visits. Out of 794 eligible parent–child dyads, 725 (91.3%)
provided informed consent and were included in the analysis. Main outcome
measures Device-specific information on SV and determinants was ascertained
using interviewer-administered survey questionnaires. The prevalence and
duration of aggregate and device-specific SV were reported. Associations with
potential determinants were investigated using multiple logistic regression
analysis. A p value less than 0.05 was considered statistically significant.
Results The prevalence of daily SV and SV ≥2 h/day constituted 53.5% and
16.3%, respectively. The majority of children aged 18–24 months (88.2%)
engaged in daily SV. TVs and mobile devices were the most commonly used screen
devices, followed by computers and video consoles. In multivariable analysis,
younger child age, Chinese ethnicity and setting rules on time of SV were
strongly and consistently associated with lower levels of any SV and SV ≥2
h/day. Parental knowledge of SV recommendations and less parental SV were
additionally associated with lower levels of SV ≥2 h/day. The number of screen
devices was not associated with children's SV. Conclusions In contrast to
recommendations, SV prevalence in children aged less than 2 years is high and
appears to increase steadily across age groups. TVs and mobile devices are
most frequently used. Improving parental knowledge of SV recommendations,
reducing parental SV and especially the implementation of strict rules on SV
time could be successful strategies to reduce SV in young children

Screen viewing behavior and sleep duration among children aged 2 and below
Abstract Background Few studies have investigated the association between screen viewing (SV) and sleep duration among young children. This study aims to examine the association between total and device-specific SV and sleep duration among children aged 2 and below. Methods We conducted a cross-sectional study of 714 Singaporean children aged 2 years and below. Parents were recruited during routine well-child clinic visits from two national polyclinics. In Singapore, all parents visit well-child clinics with their children at regular intervals for routine check-ups and vaccinations. Socio-demographic characteristics, duration of total and device-specific SV, and sleep duration were reported by parents via interviewer-administered questionnaires. Multiple linear regression analysis was used to assess associations between various types of SV and sleep duration, adjusted for socio-demographic variables. Due to significant interaction between SV and age, stratified analyses for children aged less than 6 months and those aged 7–24 months were performed. Results The prevalence of daily SV among children was 53.1%; 28.3% in children up to 6 months and 73.8% in children aged 7 to 24 months. TV viewing was reported for 44.3% of all children and mobile device SV for 30.1%. Children’s average sleep duration was 13.9 (SD = 3.5) hours daily and younger children had longer sleep duration than older ones (up to 6 months: mean = 15.6 h, SD = 3.9; 7–24 months: mean = 12.4 h, SD = 2.2; P < 0.01). In the regression analysis among all children, each 1 h per day increment in total SV was significantly associated with 0.26 h shorter sleep duration with similar significant associations for TV (β = − 0.28 h, 95%CI: -0.50, − 0.06) and mobile devices (β = − 0.35 h, 95%CI: -0.61, − 0.09). Stratified analysis revealed significantly greater reductions in sleep with higher SV among children aged 6 months and below (β = − 0.73 h, 95%CI: -1.12, − 0.34), while associations were weaker in older children (β = − 0.13 h, 95% CI: -0.24, − 0.01). Conclusions This study provides evidence for a substantial association between longer SV and shorter sleep duration among very young children. These associations appeared stronger among children aged 6 months and below as compared with those aged 7 to 24 months. Further studies are warranted to confirm our findings

Queer Play : An Anthology of Queer Women's Performance and Plays
"Through these works by both emerging and established Canadian queer artists, this diverse anthology finds itself at the intersection of queer life and art, delving into the resulting subcultures and always-changing concepts of identity and performance. In this book, queer is not just something someone is; it's also something they do. " -- p. [4] de couverture

Effect of rosiglitazone on the frequency of diabetes in patients with impaired glucose tolerance or impaired fasting glucose: a randomised controlled trial
Background Rosiglitazone is a thiazolidinedione that reduces insulin resistance and might preserve insulin secretion. The aim of this study was to assess prospectively the drugs ability to prevent type 2 diabetes in individuals at high risk of developing the condition
