Sleep And Behavioral Problems Among Preschool Children: Correlations From Pakistan Urban, Seema Zainulabdin Lasi, Somal Kayani, Noreen Afzal

Human Development Programme

The study was undertaken to explore patterns, habits, and problems for sleep in preschool children of urban Karachi, Pakistan. Two schools participated with a sample size of 297 preschool children. A cross-sectional study design was implemented. The mean age of children was 4.6 ± 0.71 years, and the male/female ratio was 49:51. The average daily sleep duration (nocturnal + daytime nap) was 9.51 ± 1.21 hours. At least one sleep problem was reported in 73% of children, the most frequently found sleep problems were, bedtime and wakeup resistance (25.6%), sleepy or tired during the day (46%), complains of growing pains …

Review Of Nighttime Temperature Effects On Long-Term Health Condition Through Sleep Studies, Sydnie Matkins

Modeling, Simulation and Visualization Student Capstone Conference

Over the past 40 years, there has been increasing interest in human sleep quality and duration. This nonsystematic review looked at over 80 peer-reviewed papers on the association among sleep, temperature, and long-term health conditions. Generally, warmer temperatures lend to poorer sleep quality, and poor sleep quality lend to mental illness and a higher risk of coronary heart disease and mortality. Future research should be to conduct a study that relies more on health records rather than questionnaires to accurately map current and future health quality.

Prospective Investigation Of Insomnia Symptoms And Sleep Duration As Risk Factors For Stroke Incidence And All-Cause Mortality In U.S Adult, Wendemi Sawadogo

Theses and Dissertations

Background and Objectives: Stroke is the second leading cause of death in the world. In the United States, on average, someone has a stroke every 40 seconds and someone dies as a result of stroke every 3.5 minutes. Identifying modifiable risk factors of stroke is therefore a public health priority. The purpose of this study was to investigate the extent to which insomnia symptoms and sleep duration contribute to stroke incidence, all-cause mortality, and explore potential causal pathways.

Methods: The Health and Retirement Study (HRS) and the REasons for Geographic And Racial Differences in Stroke (REGARDS) study were …

Sleep Duration, Sleep Quality, Excessive Daytime Sleepiness, And Chronotype In University Students In India: A Systematic Review, Christen Dunn, Octavia Goodman, Mariana Szklo-Coxe

Community & Environmental Health Faculty Publications

Introduction: Optimal sleep is an important aspect of academic performance and mental health. However, poor sleep health is often present among university students due to their lifestyle and academic requirements. University students in India have been shown to have poor sleep health. Though self-reported sleep issues have been evaluated among university students in India, these results have not been synthesized to date. We aimed to identify factors that may be associated with poor sleep health among university students in India from January 2010 to April 2021, inclusive. As a secondary aim, we sought to evaluate factors associated with sleep among …

Toxoplasma Gondii Igg Associations With Sleepwake Problems, Sleep Duration And Timing, Celine C. Corona, Ma Zhang, Abhishek Wadhawan, Melanie L. Daue, Maureen W. Groer, Aline Dagang, Christopher A.

Background: Evidence links Toxoplasma gondii (T. gondii), a neurotropic parasite, with schizophrenia, mood disorders and suicidal behavior, all of which are associated and exacerbated by disrupted sleep. Moreover, low-grade immune activation and dopaminergic overstimulation, which are consequences of T. gondii infection, could alter sleep patterns and duration. Methods: Sleep data on 833 Amish participants [mean age (SD) = 44.28 (16.99) years; 59.06% women] were obtained via self-reported questionnaires that assessed sleep problems, duration and timing. T. gondii IgG was measured with ELISA. Data were analyzed using multivariable logistic regressions and linear mixed models, with adjustment for age, sex and family …

A Better Night’S Sleep: Improving Sleep Without Medication Through Behavioral Modification, Kyle Remy

Family Medicine Clerkship Student Projects

Approximately 40 million Americans experience insomnia each year, defined by the American Academy of Sleep Medicine as unsatisfactory sleep that impacts daytime functioning. Sleep quality and duration affect daily functioning, quality of life, and overall health. Poor sleep quality/duration, increasing usage of technology before bedtime, and a growing reliance on medications for sleep have contributed to a nationally-recognized public health issue; The American Academy of Sleep Medicine has estimated annual costs of insomnia to be around $63.2 billion in worker productivity. Sleep hygiene is recommend by the American Academy of Family Physicians as a first-line approach to improving sleep. Patient …

An Exploratory Study Examining The Associations Between Sunlight Exposure, Sleep Behaviours And Sleep Outcomes During An Arctic Summer, Margaret M. Lubas, Ralitsa S. Maduro, Mariana Szklo-Coxe

Community & Environmental Health Faculty Publications

Few evidence-based recommendations exist for maintaining healthy sleep during Arctic summers. Our study aimed to examine associations between sleep hygiene, sunlight exposure and sleep outcomes in workers living in and/or near the Arctic Circle during a 24-h light period. A survey was administered July 2017 to 19 workers at 3 Arctic base camps in Northeastern Alaska. Participants with poorer sleep hygiene reported increased sleepiness (r=.62, p=0.01); this correlation remained moderately strong, albeit not statistically significant (NS), after controlling for shift work (r=.46, p=0.06). No other statistically significant correlations between sleep hygiene and sleep outcomes were found. Weekly daytime (8pm) sunlight …

Bisphenol-A And Sleep Adequacy Among Adults In The National Health And Nutrition Examination Surveys, Hind A. Beydoun, May A. Beydoun, Hueiwang Anna Jeng, Alan B. Zonderman, Shaker M. Eid

Community & Environmental Health Faculty Publications

Study Objectives: To evaluate bisphenol-A (BPA) level and its relationship to sleep adequacy in a nationally representative sample of U.S. adults.
Methods: A population-based cross-sectional study was conducted using 2005-2010 National Health and Nutrition Examination Survey whereby data were collected using in-person interviews, physical examination and laboratory testing. BPA level was measured in urine samples and analyzed as loge-transformed variable and in quartiles (< 0.9 ng/mL; 0.9 to < 1.9 ng/mL; 1.9 to < 3.7 ng/mL; 3.7+ ng/mL). Sleep adequacy was operationalized with three questions: "How much sleep do you usually get at night on weekdays or workdays?", "Have you ever told a doctor or other health professionals that you have trouble sleeping?" and "Have you ever been told by a doctor or other health professional that you have a sleep disorder?" Sleep duration was further categorized as (< 6 h, ≥ 6 h); (< 7 h, 7-8 h, > 8 h); (< 5 h, 5-6 h, 7-8 h, ≥ 9 h). Linear, binary, and ordinal logistic regression models were constructed.
Results: Loge-transformed BPA level was inversely related to sleep duration defined, in hours, as a continuous variable, a dichotomous variable (≥ 6, < 6), or an ordinal variable (≥ 9, 7-8, 5-6, < 5), after adjustment for confounders. Help-seeking behavior for sleep problems and diagnosis with sleep disorders were not significantly associated with loge-transformed BPA level in fully adjusted models.
Conclusions: Loge-transformed BPA level may be associated with fewer hours of …
