University stakeholders largely unaware and unsupportive of university pouring rights contracts with companies supplying sugar-sweetened beverages.

Background: Pouring rights contracts are agreements in which beverage companies pay universities for exclusive marketing and rights to sell sugar-sweetened beverages (SSB) in campus. This study explored university stakeholder's awareness and opinions of university pouring rights contracts. Methods: Nine hundred fifteen university stakeholders self-reported their awareness and support of pouring rights contracts along with several possible determinants of support (age, gender, nutrition education, beliefs about SSBs, beverage intake). Results: About 64.2% of participants reported no awareness of pouring rights contracts whereas only 38% reported agreeing with university pouring rights contracts. Males, undergraduate students, and those who felt individuals are responsible for their SSB consumption were more likely to support pouring rights contracts. Conclusions: University stakeholders were largely unaware of and unsupportive of pouring rights contracts. Universities are encouraged to consider the health impacts and opinions of university stakeholders when deciding whether to enter into pouring rights contracts.

A comparison of occupational physical activity and sedentary behavior patterns of nurses working 12-h day and night shifts.

Background: Past studies have reported nurses working day shifts engage in high amounts of light and moderate-intensity occupational physical activity. However, little is known regarding how occupational physical activity and sedentary behavior is accumulated within shifts and/or over consecutive shifts. Objective: This study compared occupational physical activity and sedentary behavior patterns of nurses working 12-h. day vs. 12 -h. night shifts. We hypothesized nurses working day shifts would be more active and less sedentary while at work compared to nurses working night shifts and that within shift and between shift differences would emerge. Design: Prospective-cohort study design. Settings: Midwestern trauma one academic medical center medical units (medical surgical, critical care, pediatrics, mother and baby, and other). Participants: A total of 56 registered nurses working 12-h. day and night shifts participated in this study. Methods: Occupational physical activity and sedentary behaviors (e.g., step count, time spent sitting, standing, and walking) were measured for 14 continuous days using the ActivPAL 3 micro activity monitor. Repeated measures mixed-effects regression models were used to examine the effects of shift type, consecutive shifts, and time within a shift on occupational physical activity and sedentary behaviors. Results: Nurses spent more time standing and walking, and less time sitting overall during day shifts compared to night shifts. Nurses walked less during the third consecutive night shift and stood less and sat more during the second and third consecutive night shifts, compared to day shifts. Nurses tended to walk less and sit more during the middle portion of each night shift compared to day shifts. Conclusions: Our findings suggest nurses spend more than half of each shift either standing or walking and that differential patterns of occupational physical activity and sedentary behavior exist between day and night shifts. These findings should be used to inform future interventions designed to advance the health and work performance of nurses.

Sex differences in the rate of abdominal adipose accrual during adulthood: the Fels Longitudinal Study.

OBJECTIVES: The purpose of this analysis was to evaluate sex differences in the rate of visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) accrual in adults. Secondary analyses examined differences in the rate of VAT and SAT accrual in premenopausal, perimenopausal and postmenopausal women. SUBJECTS/METHODS: Participants were 472 (60% female) non-Hispanic whites and aged 18-84 years at baseline in whom abdominal VAT and SAT were assessed using multiple-image magnetic resonance imaging at two time points, with an average follow-up of 7.3±2.6 years. Linear regression models were used to examine the effects of sex, baseline age and their interaction on rate of change per year in body composition measures (ΔBMI, ΔVAT and ΔVAT/SAT ratio (ΔVSR)) independent of baseline body composition measures, visit year, income, marital status, physical activity, smoking and alcohol intake. Secondary analyses examined differences in the rate of fat change by menopausal status (premenopausal, perimenopausal, postmenopausal). RESULTS: Levels of body mass index (BMI), VAT and VSR all increased over the 7-year period on average (P<0.001); however, the change in BMI (mean ΔBMI=+0.5%) was far smaller than for VAT (mean ΔVAT=+6.8%), SAT (mean ΔSAT=+2.4%) and VSR (mean ΔVSR=+3.6%). ΔBMI, ΔVAT and ΔSAT decreased linearly with age in both sexes (P<0.01), such that older individuals had lower rates of BMI, VAT and SAT gain, and this deceleration in BMI, VAT and SAT accrual was greater in men than women (P for interaction <0.05). ΔVSR did not vary with age in either sex but remained higher in men than women throughout adulthood. There were no differences in rate of weight or fat gain by menopausal status after adjustment for age. CONCLUSIONS: Men and women continue to accrue abdominal adiposity with age, but the rate of weight and fat gain decreases over time, particularly in men.
