The present study was designed to test the impact of rotation and timing of shifts on work--home conflict, job attitudes, health and absenteeism among the military police. A total of 3122 employees participated in the study. Discriminant analysis was used to examine the relationships between rotation and timing of shifts on the one hand, and the outcome measures on the other. Whether employees ...

We used prospective cohort data of patients with acute coronary syndrome (ACS) to compare their management on weekdays/mornings with weekends/nights, and the possible impact of this on 1-month and 1-year mortality. Analyses were evaluated using univariate and multivariate statistics. Of the 4,616 patients admitted to hospitals with ACS, 76% were on weekdays. There were no significant difference...

BACKGROUND An increased incidence of sudden infant death syndrome (SIDS) at weekends has been previously noted, although it has not been found in all studies. Where a weekend effect has been found it is most prominent on Sundays. AIM To identify the magnitude of this effect in British data before and after the fall in prevalence associated with the "back to sleep" campaign. METHODS Aggregat...

CONTEXT Increases in neonatal mortality for infants born on the weekend were last noted several decades ago. Although the current health care environment has raised concern about the adequacy of weekend care, there have been no contemporary evaluations of daily patterns of births, obstetric intervention, and case mix-adjusted neonatal mortality. OBJECTIVE To compare the neonatal mortality of ...

This paper introduces a shift rostering problem that surprisingly has not been studied in literature: the weekend shift rostering problem. It is motivated by our experience that employees’ shift preferences predominantly focus on the weekends, since many social activities happen during weekends. The Weekend Rostering Problem (WRP) addresses the rostering of weekend shifts, for which we design a...

This study aimed to describe the location and intensity of free-living physical activity in New Zealand adolescents during weekdays and weekend days using Global Positioning Systems (GPS), accelerometry, and Geographical Information Systems (GIS). Participants (n = 79) aged 12-17 years (M = 14.5, SD 1.6) recruited from two large metropolitan high schools each wore a GPS watch and an acceleromet...

This study aims to assess the long-term trend of fine particles (PM2.5; ≤2.5 μm) at two urban sites of Lahore during 2007-2011. These sites represent two distinct areas: commercial (Townhall) and residential cum industrial (Township). The highest daily mean concentrations of PM2.5 were noted as 389 and 354 μg m-3 at the Townhall and Township sites, respectively. As expected, the annual seasonal...

Urine albumin excretion measured over consecutive weekends and on repeated first morning collections from normal children showed considerable variation both during the day and from day to day in each subject. The results emphasise the need for repeated measurement of albumin excretion in children to confirm the presence of persistent microalbuminuria.

OBJECTIVE To describe the patterns (specifically comparing weekdays and weekends classified by intensities) of physical activity (PA) measured by accelerometry in adolescent girls. RESEARCH METHODS AND PROCEDURES Healthy sixth grade girls (n=1603), 11 to 12 years old, were randomly recruited from 36 schools participating in the Trial of Activity in Adolescent Girls. Age, ethnicity, socioecono...
