The relationship between sleep quantity, sleep quality and weight loss in adults: A scoping review.

Sleep is hypothesized to interact with weight gain and loss; however, modelling this relationship remains elusive. Poor sleep perpetuates a cascade of cardiovascular and metabolic consequences that may not only increase risk of adiposity, but also confound weight loss efforts. We conducted a scoping review to assess the research on sleep and weight loss interventions. We searched six databases for studies of behavioural weight loss interventions that included assessments of sleep in the general, non-clinical adult human population. Our synthesis focused on dimensions of Population, Intervention, Control, and Outcomes (PICO) to identify research and knowledge gaps. We identified 35 studies that fell into one of four categories: (a) sleep at baseline as a predictor of subsequent weight loss during an intervention, (b) sleep assessments after a history of successful weight loss, (c) concomitant changes in sleep associated with weight loss and (d) experimental manipulation of sleep and resulting weight loss. There was some evidence of improvements in sleep in response to weight-loss interventions; however, randomized controlled trials of weight loss interventions tended not to report improvements in sleep when compared to controls. We conclude that baseline sleep characteristics may predict weight loss in studies of dietary interventions and that sleep does not improve because of weight loss alone. Future studies should enrol large and diverse, normal, overweight and obese short sleepers in trials to assess the efficacy of sleep as a behavioural weight loss treatment.

Time Management Behavior Structural Equation Model Predicts Global Sleep Quality in Traditional Entry University Students.

Background: Poor sleep is commonplace among traditional entry university students. Lifestyle modifications, such as time management behaviors, may improve sleep quality by allocating sufficient time for sleep and mitigating stress-associated sleep latency inefficiencies. Purpose: The purpose of our study was to evaluate time management behaviors as predictors of sleep quality in traditional entry university students. We hypothesized time management behaviors would predict perceived control of time, which in turn, would predict global sleep quality. Methods: A cross-sectional convenience sample of university students (n=302) completed a 73-item instrument comprised of the Pittsburgh Sleep Quality Index and the Time Management Behavior scale. Model building procedures included exploratory factor analysis, confirmatory factor analysis, and structural equation modeling. Results: Our specified model identified significant paths between setting goals and priorities (ß= .261; p=.012), mechanics of time management (ß=.210; p=.043) and preference for organization (ß=.532; p<.001) for perceived control of time (R2=.300 p<.001). We further identified a significant path between perceived control of time and global sleep quality (R2=.196, p=.022). Discussion: Our study suggests time management behaviors are associated with global sleep quality. Translation to Health Education Practice: Health education interventions addressing sleep quality of traditional entry university students should consider incorporating time management behaviors.

Systematic review of electronically delivered behavioral obesity prevention interventions targeting men.

Globally, obesity persists at epidemic rates. Men are underrepresented within behavior-based obesity prevention research. As men prefer individualized, self-guided interventions, electronic delivery of treatment modalities has potential to reach this population. The purpose of this study was to systematically review primary, secondary, or tertiary behavioral obesity prevention interventions that used controlled designs; targeted men; and incorporated at least one electronically delivered treatment modality explicitly designed to elicit an intervention effect. Literature searches were delimited to peer-reviewed articles; published between 2000 and 2021; in the English language; and indexed in PsycINFO, CINHAL, MEDLINE, CENTRAL, and WOS electronic databases. Interventions satisfying inclusion criteria were critiqued for methodological quality using the Jadad Scale (0 = lowest quality; 10 = highest quality). Eleven studies satisfied the inclusion criteria (n = 1748; total participants) with five reporting group-by-time intervention effects on the primary variable targeted. Jadad scale quality assessment scores ranged from 5.00 to 9.00 with a mean of 7.72. Majority of the interventions applied a randomized control trial design (n = 10). Most interventions were theory based, with eight rooted in social cognitive theory. Behavior change strategies included self-monitoring (n = 10), personalized feedback (n = 8), health counseling (n = 8), and goal setting (n = 9). Community-level theories have the potential to guide future obesity prevention interventions targeting men.

Distracted mobile device use among street-crossing college student pedestrians: an observational approach.

ObjectiveTo estimate the incidence of mobile device use among street-crossing pedestrians and explore differences by sex and intersection type at a large public South-eastern university in the United States.ParticipantsAll instances of campus pedestrians crossing the street during the observation period (N = 4,878).MethodsVideo recordings of crosswalk activity at four locations were analyzed for pedestrian use of a mobile device while crossing.ResultsDevice use while crossing was observed 1,201 (24.6%) times. Of male crossing instances, 277 (16.8%) were coded as using a device. Of female instances, 924 (28.6%) were coded as using a device. Differences in device use while crossing were found between sexes and some intersection types.ConclusionsThis study estimates mobile device use while crossing the street and suggests differences by sex and intersection type. Future research should focus on improving understanding of the problem and evaluation of interventions to address the issue.

Examining the relationship between poor sleep health and risky driving behaviors among college students.

Objective: Risky driving behaviors, such as texting while driving, are common among young adults and increase risk of traffic accidents and injuries. We examine the relationship between poor sleep and risky driving behaviors among college students as potential targets for traffic injury prevention.Methods: Data for this study were obtained from a cross-sectional survey administered to a college student sample in the United States Midwest (n = 1,305). Sleep was measured using the Pittsburgh Sleep Quality Index (PSQI). Risky driving behaviors were measured, including sending texts/emails; reading texts/emails while driving; talking on the phone while driving; falling asleep while driving; and driving under the influence. Risky driving behavior was defined as a response of "just once," "rarely," "sometimes," "fairly often" or "regularly" (reference = "never"). Logistic regression was used to examine the relationship between sleep and risky driving, after adjusting for confounders.Results: Among participants, 75% reported sending texts/emails while driving, 82% reported reading texts/emails while driving, and 84% reported phone talking while driving; 20% reported falling asleep while driving; 8% reported driving under the influence; and 62% reported 3 or more risky behaviors. Compared to those reporting no sleep disturbance, those with sleep disturbance "once or twice a week" were more likely to report sending a text/email while driving (aOR: 2.9, 95%CI:1.7-4.9), reading a text/email while driving (aOR:3.1,95%CI:1.5-5.5), talking on the phone while driving (aOR:1.9, 95%CI:1.0-3.4), and falling asleep while driving (aOR:3.4,95%CI:1.5-7.4). Compared to those reporting no daytime dysfunction, those reporting issues "once or twice a week" were more likely to report talking on the phone while driving (aOR:1.7, 95%CI:1.1-2.7) and falling asleep while driving (aOR:3.6,95%CI:2.3-5.6).Conclusions: Future research may consider designing behavioral interventions that aim to improve sleep, reduce drowsy driving among young adults.

Modeling Risk Factors for Sleep- and Adiposity-Related Cardiometabolic Disease: Protocol for the Short Sleep Undermines Cardiometabolic Health (SLUMBRx) Observational Study.

BACKGROUND: Obesity and short sleep duration are significant public health issues. Current evidence suggests that these conditions are associated with cardiovascular disease, metabolic syndrome, inflammation, and premature mortality. Increased interest in the potential link between obesity and short sleep duration, and its health consequences, has been driven by the apparent parallel increase in the prevalence of both conditions in recent decades, their overlapping association with cardiometabolic outcomes, and the potential causal connection between the two health issues. The SLUMBRx (Short Sleep Undermines Cardiometabolic Health) study seeks to contribute to the development of a comprehensive adiposity-sleep model while laying the groundwork for a future research program that will be designed to prevent and treat adiposity- and sleep-related cardiometabolic disease risk factors. OBJECTIVE: This SLUMBRx study aims to address 4 topics pertinent to the adiposity-sleep hypothesis: the relationship between adiposity and sleep duration; sex-based differences in the relationship between adiposity and sleep duration; the influence of adiposity indices and sleep duration on cardiometabolic outcomes; and the role of socioecological factors as effect modifiers in the relationship between adiposity indices, sleep, and cardiometabolic outcomes. METHODS: SLUMBRx will employ a large-scale survey (n=1000), recruiting 159 participants (53 normal weight, 53 overweight, and 53 obese) to be assessed in 2 phases. RESULTS: SLUMBRx was funded by the National Institutes of Health, Heart, Lung, and Blood Institute through a K01 grant award mechanism (1K01HL145128-01A1) on July 23, 2019. Institutional Review Board (IRB) approval for the research project was sought and obtained on July 10, 2019. Phase 1 of SLUMBRx, the laboratory-based component of the study, will gather objective adiposity indices (air displacement plethysmography and anthropometrics) and cardiometabolic data (blood pressure, pulse wave velocity and pulse wave analysis, and a blood-based biomarker). Phase 2 of SLUMBRx, a 1-week, home-based component of the study, will gather sleep-related data (home sleep testing or sleep apnea, actigraphy, and sleep diaries). During phase 2, detailed demographic and socioecological data will be collected to contextualize hypothesized adiposity and sleep-associated cardiometabolic disease risk factors. Collection and analyses of these data will yield information necessary to customize future observational and intervention research. CONCLUSIONS: Precise implementation of the SLUMBRx protocol promises to provide objective and empirical data on the interaction between body composition and sleep duration. The hypotheses that will be tested by SLUMBRx are important for understanding the pathogenesis of cardiometabolic disease and for developing future public health interventions to prevent its conception and treat its consequences.

Health Education Specialist Practice Analysis II 2020: Processes and Outcomes.

Introduction. The Health Education Specialist Practice Analysis II 2020 (HESPA II 2020) described the contemporary practice of health education specialists across work settings at entry and advanced levels. The purpose of the HESPA II 2020 manuscript was to report the research process and resulting data associated with the HESPA II 2020 and to provide recommendations for future practice analyses in health education. Method. Two data collection instruments were developed with the assistance of a 17-member Health Education Practice Panel to survey practicing health education specialists on the knowledge and skills needed in their ongoing roles. The instruments were designed to assess the degree to which the elements of the model had importance to practice (Importance), how often health education specialists performed the elements of the model (Frequency), and the point in time that health education specialists were expected to perform the various elements of the model (Performance Expectation). Composite scores for Sub-Competencies were calculated and subgroup comparisons were conducted to distinguish between levels of practice. Results. A total of 3,851 health education specialists provided usable responses. The final validated hierarchical model included eight Areas of Responsibility, 35 Competencies, and 193 Sub-Competencies. Of the Sub-Competencies, 114 were Entry level, 59 Advanced 1 level, and 20 Advanced 2 level. In addition, 145 knowledge items were verified. Discussion. HESPA II 2020 produced a validated hierarchical model descriptive of current practice of health education specialists across work settings. The results have implications for professional preparation, professional development, and certification.

A systematic review of obesity interventions targeting anthropometric changes in youth with intellectual disabilities.

Due to the increased prevalence of obesity and disparity experienced by youth with intellectual disabilities, efforts to synthesize existing knowledge of interventions to attenuate obesity within this marginalized population is imperative. The purpose of this investigation is to systematically analyze interventions targeting anthropometric changes in youth with intellectual disabilities. A search of Cumulative Index of Nursing and Allied Health Literature, Educational Resources Information Center, Medical Literature Analysis and Retrieval System Online, and Psychological Information Database was conducted for the time frame of January 2006 to October 2016. Data extraction resulted in a total of 10 interventions that met inclusion criteria. Included studies mainly comprised participants having mild-to-moderate intellectual disability with diverse comorbidities. Five studies indicated significant positive outcomes in at least one anthropometric measure. The majority of programs utilized physical activity targeting individual-level change as the primary intervention modality. Weaknesses of the reviewed studies and inconclusive evidence indicate the need for additional research to gauge the effectiveness of interventions to treat obesity among youth with intellectual disabilities.

Mobile device use while crossing the street: Utilizing the theory of planned behavior.

Every year, thousands of pedestrians are killed and tens-of-thousands are nonfatally injured as a result of traffic crashes. The year 2016 holds the record for the most pedestrians killed in one year since 1990. Mobile device use while crossing the street has been associated with unsafe crossing behaviors and gait abnormalities, potentially increasing the risk of pedestrian injury or death. Expanding upon the small body of literature, the present study utilized the theory of planned behavior to guide the development of a questionnaire used to collect data from 480 adults on predictors of intentions to use a mobile device while crossing the street. Questionnaire development involved one round of expert panel review (N = 4), subsequent pilot testing of a revised questionnaire, and a test-retest reliability assessment. Results demonstrate that attitude toward the behavior, subjective norm, and perceived behavioral control significantly predicted the intention to use a mobile device while crossing the street in this population. Such a questionnaire can be used in the design and evaluation of TPB-based interventions to decrease distracted mobile device use while crossing the street.

Driving After Drinking Alcohol Associated with Insufficient Sleep and Insomnia among Student Athletes and Non-Athletes.

INTRODUCTION: The proportion of university/college students (UCS) consuming alcohol is similar to the number of those reporting poor sleep, at approximately 30%, the proportion being greater in student athletes (SA). What remains to be understood is if poor sleep potentiates risky behaviors. OBJECTIVE: Our aim was to examine the association among sleep difficulties, insomnia symptoms, and insufficient sleep on the risk of driving under the influence of alcohol in a sample of UCS and whether these associations were more pertinent in SA. METHODS: Data from the National University/College Health Assessment was used from the years 2011⁻2014. Questions on number of drinks consumed and behaviors such as driving after drinking alcohol were related to answers to questions pertaining to sleep difficulties, insufficient sleep, and insomnia symptoms. RESULTS: Mean alcohol intake was of about 3 drinks; SA consumed significantly more than student non-athletes (SNA). Binge-drinking episodes were significantly higher among SA than SNA. Difficulty sleeping was associated with an increased likelihood of driving after any drinks and after 5 or more drinks in both groups, effects being stronger among SA. Insomnia was associated with an increased likelihood of driving after any drinks and after 5 or more drinks in SA and after 5 or more drinks in SNA. These effects were stronger among athletes. CONCLUSION: The present study found that self-reported difficulties sleeping, insomnia symptoms, and insufficient sleep are associated with driving after drinking alcohol. This relationship applied to driving after drinking any alcohol or binge drinking and was again stronger among SA than SNA.

Workplace-Related Factors Associated With Employees' Standing Time at Work: A Research Brief.

PURPOSE: The purpose of this study was to identify the relationship between work-related, individual, and environmental factors and self-reported standing time during the workday. DESIGN: Cross-sectional study design. SETTING: Participants were recruited from a large, public university in the southeastern United States. MEASURES: Data were collected through an 87-item online survey using previously validated scales that assessed workplace standing time, demographic variables, work-related psychosocial factors, and workplace environment factors. ANALYSIS: One-way analysis of variance, Pearson correlation coefficients, and nonparametric tests were used to determine univariate relationships between standing time and independent work-related variables and demographic factors. RESULTS: Mean standing time among the sample (n = 502) was 72.49 minutes (standard deviation = 73.48) daily. There was a significant relationship between standing time and barrier self-efficacy for standing at work, self-regulation strategies, social norms, local connectivity in the workplace, overall connectivity in the workplace, and proximity of coworkers. Standing time was significantly higher for men, employees with an advanced degree, employees with a standing desk, and faculty. CONCLUSION: Health promotion researchers and practitioners should consider factors at multiple levels of influence when designing studies to explore workplace sedentary behavior. The findings regarding variations in workplace behavior by employee subgroups should be taken into consideration when designing future studies in the workplace.

Examination of associations between risky driving behaviors and hazardous drinking among a sample of college students.

OBJECTIVE: Hazardous drinking is associated with other risky behaviors and negative health-related outcomes. This study examined covariation between hazardous drinking scores and the following risky driving behaviors: Falling asleep while driving, texting (receiving and sending) while driving, and driving after consuming alcohol. METHODS: The participants in this study were a sample of undergraduate students (N = 1,298) who were enrolled in an introductory health course at a large Southeastern university in spring 2016 and completed an online health survey that assessed hazardous drinking, falling asleep while driving, texting while driving, and driving after consuming alcohol. We conducted a series of 2-step regression analyses to examine covariation between hazardous drinking scores (using the Alcohol Use Disorders Identification Test-Consumption [AUDIT-C]) and the risky driving behaviors of interest. RESULTS: We found that the majority of participants did not drink and drive (91.8%), nor did they fall asleep while driving (80.4%); however, the majority did read a text while driving (81.7%) and sent a text while driving (75.3%). In the full multivariable model, hazardous drinking score was positively associated with drinking and driving (step 2 odds ratio [OR] = 1.28, 95% confidence interval [CI], 1.18, 1.38) and sending a text message while driving (step 2 b = 0.19, P = .01). Hazardous drinking score was also positively associated with reading a text while driving (step 1 b = 0.14, P < .001) and falling asleep while driving (step 1 b = 0.02, P = .02) in the model only controlling for demographic characteristics. The analyses also indicated covariability between the following risky driving behaviors: (1) drinking and driving/reading a text message while driving, (2) drinking and driving/falling asleep and driving, (3) reading a text while driving/sending a text while driving, and (4) sending a text while driving/sleeping and driving. CONCLUSION: The findings of this study indicate a need for interventions discouraging both hazardous drinking and risky driving behaviors in college student populations; recommendations to reduce risky driving and hazardous drinking are discussed.

Ecological Influences on Employees' Workplace Sedentary Behavior: A Cross-Sectional Study.

PURPOSE: The purpose of this study was to explore the relationship between ecological factors and occupational sedentary behavior (SB). DESIGN: Cross-sectional online survey. SETTING: Participants were employees recruited from a large, public university in the Southeastern United States from August to November 2016. PARTICIPANTS: The final sample included 527 (56% response rate) employees. MEASURES: Data were collected through an 87-item survey using previously validated scales that assessed occupational SB, perceived behavioral control, barrier self-efficacy, self-regulation strategies, organizational social norms, office environment, and worksite climate. ANALYSIS: One-way analysis of variance analyses were used to determine differences in occupational SB by demographic factors. A multivariate regression model was used to determine significant ecological determinants of occupational SB. RESULTS: Mean SB was 342.45 (standard deviation = 133.25) minutes. Significant differences in SB were found by gender, education, and employment classification. Barrier self-efficacy and workplace connectivity, which evaluates the spatial layout of the office setting that may impact mobility within the workplace, were significant predictors of SB in the multivariate model. CONCLUSION: Results from this study provide new information regarding the potential impact of workplace barriers and connectivity on occupational SB. The findings from this study support the inclusion of intervention modalities to minimize workplace barriers and increase workplace connectivity to increase workplace mobility and decrease SB.

Sex-Specific Impact of Spiritual Beliefs and Sleep Quality on Degree of Psychological Distress.

The purpose of this study was to test a set of hypotheses suggesting sleep quality and spiritual beliefs differed according to degree of psychological distress and biological sex. The Pittsburgh Sleep Quality Index measured sleep quality, the Beliefs and Values Scale measured spiritual beliefs, and the Kessler-6 Psychological Distress Scale measured distress. A factorial MANOVA tested the model. Higher sleep quality and greater spiritual beliefs were associated with lower levels of distress. Women exhibited lower sleep quality than men, whereas spiritual beliefs were equivalent between sexes. To decrease psychological distress, interventions should improve sleep quality and increase spiritual engagement.

Two-Year Outcomes of the Enabling Mothers to Prevent Pediatric Obesity Through Web-Based Education and Reciprocal Determinism (EMPOWER) Randomized Control Trial.

BACKGROUND: Childhood overweight and obesity is a public health epidemic with far-reaching medical, economic, and quality of life consequences. Brief, web-based interventions have received increased attention for their potential to combat childhood obesity. The purpose of our study was to evaluate a web-based, maternal-facilitated childhood obesity prevention intervention dubbed Enabling Mothers to Prevent Pediatric Obesity Through Web-Based Education and Reciprocal Determinism (EMPOWER), for its capacity to elicit sustained effects at the 2-year postintervention follow-up mark. METHOD: Two interventions were evaluated using a randomized controlled trial design. The experimental, EMPOWER arm received a social cognitive theory intervention ( n = 29) designed to improve four maternal-facilitated behaviors in children (fruit and vegetable consumption, physical activity, sugar-free beverage intake, screen time). The active control arm received a knowledge-based intervention dubbed Healthy Lifestyles ( n = 28), which also targeted the same four behaviors. RESULTS: We identified a significant group-by-time interaction of small effect size for child fruit and vegetable consumption ( p = .033; Cohen's f = 0.139) in the EMPOWER group. The construct of maternal-facilitated environment was positively associated to improvements in child fruit and vegetable behavior. We also found significant main effects for child physical activity ( p = .024; Cohen's f = 0.124); sugar-free beverage intake ( p < .001; Cohen's f = 0.321); and screen time ( p < .001; Cohen's f = 0.303), suggesting both groups improved in these behaviors over time. CONCLUSIONS: The EMPOWER arm of the trial resulted in an overall increase of 1.680 daily cups of fruits and vegetables consumed by children, relative to the comparison group ( p < .001, 95% confidence interval = [1.113, 2.248]). Web-based maternal-facilitated interventions can induce sustained effects on child behaviors.

Work Site-Based Environmental Interventions to Reduce Sedentary Behavior: A Systematic Review.

OBJECTIVE: The purpose of this investigation was to systematically review work site-based, environmental interventions to reduce sedentary behavior following preferred reporting items for systematic reviews and meta-analyses guidelines. DATA SOURCE: Data were extracted from Medical Literature Analysis and Retrieval System Online, Cochrane Central Register of Controlled Trials, and Web of Science between January 2005 and December 2015. STUDY INCLUSION AND EXCLUSION CRITERIA: Inclusion criteria were work site interventions, published in peer-reviewed journals, employing environmental modalities, targeting sedentary behavior, and using any quantitative design. Exclusion criteria were noninterventions and non-English publications. DATA EXTRACTION: Data extracted included study design, population, intervention dosage, intervention activities, evaluation measures, and intervention effects. DATA SYNTHESIS: Data were tabulated quantitatively and synthesized qualitatively. RESULTS: A total of 15 articles were identified for review and 14 reported statistically significant decreases in sedentary behavior. The majority of studies employed a randomized controlled trial design (n = 7), used inclinometers to measure sedentary behavior (n = 9), recruited predominantly female samples (n = 15), and utilized sit-to-stand desks as the primary intervention modality (n = 10). The mean methodological quality score was 6.2 out of 10. CONCLUSION: Environmental work site interventions to reduce sedentary behavior show promise because work sites often have more control over environmental factors. Limitations of this intervention stream include inconsistent measurement of sedentary behavior, absence of theoretical frameworks to guide program development, and absence of long-term evaluation. Future studies should include clear reporting of intervention strategies and explicit operationalization of theoretical constructs.

Using the Theory of Planned Behavior to predict HPV vaccination intentions of college men.

OBJECTIVE: The purpose of this study was to test Theory of Planned Behavior (TPB) constructs in predicting human papillomavirus (HPV) vaccination behavioral intentions of vaccine-eligible college men. PARTICIPANTS: Participants were unvaccinated college men aged 18-26 years attending a large public university in the southeastern United States during Spring 2015. METHODS: A nonexperimental, cross-sectional study design was employed. Instrumentation comprised a qualitative elicitation study, expert panel review, pilot test, test-retest, and internal consistency, construct validity, and predictive validity assessments using data collected from an online self-report questionnaire. RESULTS: The sample consisted of 256 college men, and the final structural model exhibited acceptable fit of the data. Attitude toward the behavior (ß = .169) and subjective norm (ß = 0.667) were significant predictors of behavioral intention, accounting for 58% of its variance. CONCLUSIONS: Practitioners may utilize this instrument for the development and evaluation of TPB-based interventions to increase HPV vaccination intentions of undergraduate college men.

Applying a New Theory to Alter Binge Drinking Behavior in College Students.

Binge drinking is a serious public health problem in the United States, where it is estimated that 17.6% adults binge drink. Binge drinking is highest among college students. There is need for effective binge drinking interventions. Recently a new health behavior theory has been proposed called the multitheory model of health behavior change. The purpose of this article is to describe the application of the multitheory model for changing binge drinking behavior to a behavior of responsible drinking or abstaining from alcohol. A framework for an intervention and its testing is presented.

Using Multitheory Model of Health Behavior Change to Predict Adequate Sleep Behavior.

The purpose of this article was to use the multitheory model of health behavior change in predicting adequate sleep behavior in college students. A valid and reliable survey was administered in a cross-sectional design (n = 151). For initiation of adequate sleep behavior, the construct of behavioral confidence (P < .001) was found to be significant and accounted for 24.4% of the variance. For sustenance of adequate sleep behavior, changes in social environment (P < .02), emotional transformation (P < .001), and practice for change (P < .001) were significant and accounted for 34.2% of the variance.
