Sleep Duration and Weight Gain among Students at a Historically Black University

Objective: We investigated sex differences in sleep and examined the association between objectively-measured sleep characteristics and weight gain among 54 black students at a historically black university in spring 2018. Methods: Participants wore a wearable tracker (Fitbit Alta) for an average of 68 days of sleep over the spring semester and 5.5 days of sleep over the spring break. They also completed a questionnaire. Results: Average sleep duration was 6 hours 35 minutes. More women had short sleep (< 7 hours / night) than men (92.1% vs 43.8%; p < .001). Women had shorter sleep (6 hours 24 minutes vs 7 hours 1 minute; p = .003), shorter naps (2 hours 4 minutes vs 2 hours 30 minutes; p = .043), and lower sleep efficiency (93.0% vs 94.1%; p = .048) than men. More women than men experienced weight gain (79.0% vs 68.8%, p < .05). We found an inverse relationship between sleep duration and weight gain in both sexes (r = -0.42, p < .05). Conclusions: Appropriate sleep and weight management should be considered to address sex disparities in sleep and weight gain among black students at historically black universities.

Orientation: Within the new South African socio-political context this research focussed on lecturers’ at historically Black universities who were confronted with unresolved experiences in their relationship with management. The analysis of these experiences provided an in-depth understanding of systems psychodynamics in tertiary education.Research purpose: The purpose of the research was to describe the experiences of nine lecturers in a particular historically Black university (HBU), in order to analyse and interpret the conscious and unconscious dynamics operating in their relationship with management.Motivation for the study: The researchers were interested in the in-depth psychological experiences of lecturers at this HBU as a platform towards understanding present day South African lecturing experiences.Research design, approach and method: Qualitative, descriptive research was used. Hermeneutic phenomenology, using the systems psychodynamic perspective, allowed for the description and interpretation of the lecturers’ experiences of their relationship with management. In-depth interviews with nine lecturers were thematically analysed which resulted in five themes. Five working hypotheses were formulated and integrated into the research hypothesis.Main findings: Five themes manifested, namely, the (k)not of performance, mutual disqualification and mistrust, White lecturers and Black management, power struggle and the (k)not of relationship.Practical/managerial implications: The research highlighted the importance of understanding the psychodynamics operating in the relationship between lecturers and management as a result of certain ineffective socio-technical aspects in the organisation.Contribution/value-add: The research contributed towards knowledge about inter-group relations between different role players in HBUs and how these dynamics impact on the performance of both lecturers and management.

Abstract Objective To evaluate the influence of health-related behaviors including food intake, physical activity, sleep time, smoking habits, stress, depression, and optimism on excessive gestational weight gain (GWG) among women with overweight and obesity. Methods A cross-sectional study was conducted at the Women's Hospital of the Universidade de Campinas, Campinas, state of São Paulo, Brazil, with 386 mediate postpartum women that fit the inclusion criteria of ≥ 19 years old, first prenatal care visit at or before 14 weeks, and single live baby. Dietary habits, physical exercise practice, sleep duration, smoking and alcohol habits were self-reported. Psychosocial history was evaluated using the Edinburgh Postpartum Depression Scale (EPDS), Perceived Stress Scale (PSS), and Life Orientation Test-Revised (LOT-R). Sociodemographic, obstetric, anthropometric, and neonatal data were retrieved from medical records. Descriptive statistics and stepwise logistic regression were performed. Results The prevalence of overweight and obesity was 29.27% and 24.61%, respectively, according to the body mass index (BMI). Excessive GWG was observed in 47.79% of women with overweight and in 45.26% of women with obesity. Excessive GWG among overweight and obese women was associated with inadequate vegetable and bean consumption (odds ratio [OR] = 2.95, 95% confidence interval [CI]: 1.35–6.46 and OR = 1.91; 95%CI: 1.01–3.63, respectively) and stress (OR = 1.63; 95%CI 1.01–2.64). After adjustment by maternal age, multiparity, sleep duration, smoking, and alcohol intake, we found that stress (PSS ≥ 20) was associated with excessive GWG in women with overweight or obesity (OR: 1.75; 95%CI: 1.03–2.96). Conclusion Among women with overweight and obesity, stress is the main variable associated with excessive GWG. Inadequate vegetables and beans consumption also showed association with excessive GWG.

Abstract Background Older adults are recommended to sleep 7–8 h/day. Time in bed (TIB) differs from sleep duration and includes also the time of lying in bed without sleeping. Long TIB (≥9 h) are associated with self-reported sedentary behavior, but the association between objectively measured physical activity, sedentary behavior and TIB is unknown. Methods This study was based on cross-sectional analysis of the Healthy Ageing Network of Competence (HANC Study). Physical activity and sedentary behaviour were measured by a tri-axial accelerometer (ActiGraph) placed on the dominant wrist for 7 days. Sedentary behavior was classified as < 2303 counts per minute (cpm) in vector magnitude and physical activity intensities were categorized, as 2303–4999 and ≥ 5000 cpm in vector magnitude. TIB was recorded in self-reported diaries. Participants were categorized as UTIB (usually having TIB 7–9 h/night: ≥80% of measurement days), STIB (sometimes having TIB 7–9 h/night: 20–79% of measurement days), and RTIB (rarely having TIB 7–9 h/night: < 20% of measurement days). Multinominal regression models were used to calculate the relative risk ratios (RRR) of being RTIB and STIB by daily levels of physical activity and SB, with UTIB as the reference group. The models were adjusted for age, sex, average daily nap length and physical function. Results Three hundred and fourty-one older adults (median age 81 (IQR 5), 62% women) were included with median TIB of 8 h 21 min (1 h 10 min)/day, physical activity level of 2054 (864) CPM with 64 (15) % of waking hours in sedentary behavior. Those with average CPM within the highest tertile had a lower RRR (0.33 (0.15–0.71), p = 0.005) for being RTIB compared to those within the lowest tertile of average CPM. Accumulating physical activity in intensities 2303–4999 and ≥ 5000 cpm/day did not affect the RRR of being RTIB. RRR of being RTIB among highly sedentary participants (≥10 h/day of sedentary behavior) more than tripled compared to those who were less sedentary (3.21 (1.50–6.88), p = 0.003). Conclusions For older adults, being physically active and less sedentary was associated with being in bed for 7–9 h/night for most nights (≥80%). Future longitudinal studies are warranted to explore the causal relationship sbetween physical activity and sleep duration.
