Relationships between sleep quality, physical fitness and body mass index in college freshmen. Chang S P,Chen Y H The Journal of sports medicine and physical fitness AIM:The aim of this study was to analyze the association between poor sleep quality with BMI and health-related physical fitness among college freshmen. METHODS:The participants were college freshmen enrolled in 2011. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). A global PSQI score of 5 and total sleep time (TST) of 7 hours were used to differentiate between poor and good sleepers. Various Body Mass Index (BMI) ranges were used to categorize groups of underweight, normal weight and overweight. Health-related fitness was measured by Sit-And-Reach, Curl-Up, and Run/Walk Tests. RESULTS:A substantial proportion of college students were affected by poor sleep quality. Significantly more females were poor sleepers and had a TST shorter than 7 hrs. No difference in the proportions of participants categorized based on BMI between male and female students. Males generally scored better on health-related physical fitness tests than females. All results of physical fitness tests were significantly correlated with BMI, sleep quality (global PSQI), and TST in both males and females. Pool sleepers were associated with a higher BMI and lower performance of physical fitness. TST was negatively associated with BMI and time length to complete 1600-m or 800-m Run/Walk Test, and positively correlated with the performance of Sit-And-Reach and Curl-Up Tests in both genders. CONCLUSION:Poorer sleep quality and decreased TST were associated with lower performance in health-related physical fitness assessment among college students. Health promotion and educational programs for young adults should emphasize the importance of sleep quality and TST.
The mediating roles of sleep quality and sedentary behavior between physical fitness and depression among female college freshmen. Journal of American college health : J of ACH This study aimed to investigate interactions among physical fitness, sleep quality, sedentary behavior, and depression among female college freshmen. A cohort of 1,514 Chinese female college freshmen ( = 18.8 ± .63) were recruited from four universities. Participants completed a survey assessing depression, sleep quality (sleep duration and sleep onset latency), and sedentary behavior, and performed physical fitness measurements. Physical fitness indexes were associated with sleep quality and sedentary behavior ( < .05) but not with depression. Depression was positively associated with sedentary behavior and sleep onset latency, but negatively associated with sleep duration ( < .01). The model tests revealed that sleep quality ( = -.57, < .01) and sedentary behavior ( = .14, < .01) served as mediators between physical fitness and depression, respectively. Increasing sleep quality and minimizing sedentary behavior may build resilience to depression among Chinese female college freshmen. 10.1080/07448481.2020.1809431
Sleep and health-related physical fitness in children and adolescents: a systematic review. Sleep science (Sao Paulo, Brazil) OBJECTIVES:The aim of this systematic review was to summarize the evidence on the associations between the sleep duration or sleep quality and cardiorespiratory and muscular fitness in children and adolescents aged 6-19 years. MATERIAL AND METHODS:This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta- analyses (PRISMA) and was registered with the international prospective register of systematic reviews PROSPERO network. Three databases (PubMed, SPORTDiscus and Science Direct) were searched until October 2019 for scientific articles concerning sleep duration, sleep quality and physical fitness. RESULTS:Six articles, including 5797 participants, from 11 different countries, were included in the current systematic review. CONCLUSION:Longer periods of sleep and better sleep quality were associated with higher levels of physical fitness. 10.5935/1984-0063.20200125
Association of Physical Fitness, Screen Time, and Sleep Hygiene According to the Waist-to-Height Ratio in Children and Adolescents from the Extreme South of Chile. Healthcare (Basel, Switzerland) OBJECTIVE:To analyze the perception of physical fitness, screen time, and self-reported sleep hygiene in children and adolescents (CA) from the extreme south of Chile and its associations with waist-to-height ratio (WtHr). MATERIAL AND METHODS:An observational cross-sectional study was conducted in a sample of 594 schoolchildren from 5th to 8th grade of primary education, belonging to municipal educational establishments in the Magallanes region, Chile. Cardiorespiratory fitness was assessed through the 20-m shuttle run test, muscle strength through handgrip and the standing broad jump test, physical fitness perception through the International Fitness Scale, and central obesity through the waist-to-height index. In addition, sleep hygiene and screen time were measured. RESULTS:More than 92% of CA spent more than two hours a day watching or using screens. In addition, CA with excess central adiposity had a lower perception of physical fitness, and lower muscle strength and cardiorespiratory fitness compared to CA with normal values of adiposity. CONCLUSIONS:CA of the present study spent a high number of hours watching or using screens and had poor sleep quality. In addition, excessive central adiposity was associated with lower physical fitness. 10.3390/healthcare10040627
Subjective sleep quality and association with depression syndrome, chronic diseases and health-related physical fitness in the middle-aged and elderly. Hsu Min-Fang,Lee Kang-Yun,Lin Tsung-Ching,Liu Wen-Te,Ho Shu-Chuan BMC public health BACKGROUND:As a complex phenomenon, sleep quality is difficult to objectively define and measure, and multiple factors related to sleep quality, such as age, lifestyle, physical activity, and physical fitness, feature prominently in older adult populations. The aim of the present study was to evaluate subjective sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and to associate sleep quality with health-related physical fitness factors, depressive symptoms, and the number of chronic diseases in the middle-aged and elderly. METHODS:We enrolled a total of 283 middle-aged and elderly participants from a rehabilitation clinic or health examination department. The PSQI was used to evaluate sleep quality. The health-related fitness assessment included anthropometric and physical fitness parameters. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression Scale (CES-D) short form. Data were analyzed with SPSS 18.0, and descriptive statistics and logistic regression analysis were used for the analyses. RESULTS:Overall, 27.9% of participants in this study demonstrated bad sleepers (with a PSQI score of > 5), 10.2% of study participants frequently used sleep medication to help them fall asleep, and 6.0% reported having significant depressive symptoms (with a CES-D score of ≥10). There are two major findings: (1) depression symptoms, the number of chronic diseases, self-rated health, and arthritis were significantly associated with a poor sleep quality, and (2) the 2-min step test was associated with longer sleep latency. These results confirmed that the 2-min step was associated with a longer sleep latency among the health-related physical fitness items. CONCLUSIONS:Our study found that depressive syndrome, chronic disease numbers, a poor self-rated health status, and arthritis were the main risk factors that influenced subjective sleep quality. 10.1186/s12889-021-10206-z
Associations of sleep duration with physical fitness performance and self-perception of health: a cross-sectional study of Taiwanese adults aged 23-45. Gu Ming,Liu Chia-Chen,Hsu Chi-Chieh,Lu Chi-Jie,Lee Tian-Shyug,Chen Mingchih,Ho Chien-Chang BMC public health BACKGROUND:The relationship between sleep duration and physical fitness is one aspect of sleep health. Potential factors associated with sleep duration interfere with physical fitness performance, but the impact trends on physical fitness indicators remain unclear. METHODS:This study examined associations between sleep duration and physical fitness among young to middle-aged adults in Taiwan. A total of 42,781 Taiwanese adults aged 23-45 participated in the National Physical Fitness Examination Survey 2013 (NPFES-2013) in Taiwan between October 2013 and March 2014. A standardized structural questionnaire was used to record participants' sleep duration, which was stratified as short (< 6 h/day (h/d)), moderate (6-7 h/d; 7-8 h/d; 8-9 h), and long (≥ 9 h/d) sleep duration groups. Physical fitness was assessed based on four components: body composition (body mass index [BMI], waist-to-height ratio [WHtR], and waist-to-hip ratio [WHR]), muscle strength and endurance (1-min bent-leg sit-up test [BS]), flexibility (sit-and-reach test [SR]), and cardiorespiratory endurance index (3-min step test [CEI]). RESULTS:By using analysis of covariance (ANCOVA), after sex grouping and age adjustment, we observed that sleep duration was significantly associated with obesity, functional fitness, and self-perception of health. The sleep duration for low obesity-related values (BMI, WHtR, and WHR) for men was 7-9 h/d, and that for women was 7-8 h/d. Sleeping more than 8 h/d showed poor functional fitness performances (BS and SR). For both sexes, sleep duration of 8-9 h/d was the optimal sleep duration for self-perceptions of health. CONCLUSIONS:Our research found that there were wide and different associations of sleep duration with physical fitness and self-perception of health among Taiwanese adults aged 23-45, and there were differences in these associated manifestations between men and women. This study could be of great importance in regional public health management in Taiwan, and provide inspirations for clinical research on physical fitness. 10.1186/s12889-021-10636-9
Psychometric Evaluation of the PSQI in U.S. College Students. Dietch Jessica R,Taylor Daniel J,Sethi Kevin,Kelly Kimberly,Bramoweth Adam D,Roane Brandy M Journal of clinical sleep medicine : JCSM : official publication of the American Academy of Sleep Medicine STUDY OBJECTIVES:Examine the psychometric properties of the PSQI in two U.S. college samples. METHODS:Study I assessed convergent and divergent validity in 866 undergraduates who completed a sleep diary, PSQI, and other sleep and psychosocial measures. Study II assessed PSQI insomnia diagnostic accuracy in a separate sample of 147 healthy undergraduates with and without insomnia. RESULTS:The PSQI global score had only moderate convergent validity with sleep diary sleep efficiency (prospective global measure of sleep continuity; r = 0.53), the Insomnia Severity Index (r = 0.63), and fatigue (r = 0.44). The PSQI global score demonstrated good divergent validity with measures of excessive daytime sleepiness (r = 0.18), circadian preference (r = -0.08), alcohol (r = 0.08) and marijuana (r = 0.05) abuse scales, and poor divergent validity with depression (r = 0.48), anxiety (r = 0.40), and perceived stress (r = 0.33). Examination of other analogous PSQI and sleep diary components showed low to moderate convergent validity: sleep latency (r = 0.70), wake after sleep onset (r = 0.37), sleep duration (r = 0.51), and sleep efficiency (r = -0.32). Diagnostic accuracy of the PSQI to detect insomnia was very high (area under the curve = 0.999). Sensitivity and specificity were maximized at a cutoff of 6. CONCLUSIONS:The PSQI demonstrated moderate convergent validity compared to measures of insomnia and fatigue and good divergent validity with measures of daytime sleepiness, circadian phase preference, and alcohol and marijuana use. The PSQI demonstrated considerable overlap with depression, anxiety, and perceived stress. Therefore, caution should be used with interpretation. 10.5664/jcsm.6050
Assessment of sleep disturbance in oral lichen planus and validation of PSQI: A case-control multicenter study from the SIPMO (Italian Society of Oral Pathology and Medicine). Adamo Daniela,Calabria Elena,Coppola Noemi,Lo Muzio Lorenzo,Giuliani Michele,Azzi Lorenzo,Maurino Vittorio,Colella Giuseppe,Rauso Raffaele,Montebugnoli Lucio,Gissi Davide Bartolomeo,Gabriele Mario,Nisi Marco,Sardella Andrea,Lodi Giovanni,Varoni Elena Maria,Giudice Amerigo,Antonelli Alessandro,Cabras Marco,Gambino Alessio,Vescovi Paolo,Majorana Alessandra,Bardellini Elena,Campisi Giuseppina,Panzarella Vera,Spadari Francesco,Marino Sonia,Pentenero Monica,Sutera Samuele,Biasotto Matteo,Gobbo Margherita,Guarda Nardini Luca,Romeo Umberto,Tenore Gianluca,Serpico Rosario,Lucchese Alberta,Lajolo Carlo,Rupe Cosimo,Aria Massimo,Gnasso Agostino,Mignogna Michele Davide, Journal of oral pathology & medicine : official publication of the International Association of Oral Pathologists and the American Academy of Oral Pathology BACKGROUND:The wellbeing of oral lichen planus patients (OLPs) may be strongly influenced by a poor quality of sleep (QoS) and psychological impairment. The aims were to analyze the prevalence of sleep disturbance, anxiety, and depression in OLPs and to validate the Pittsburgh Sleep Quality Index (PSQI) in OLPs. METHODS:Three hundred keratotic OLPs (K-OLPs), 300 with predominant non-keratotic OLP (nK-OLPs), and 300 controls were recruited in 15 Italian universities. The PSQI, Epworth Sleepiness Scale (ESS), Hamilton Rating Scales for Depression and Anxiety (HAM-D and HAM-A), Numeric Rating Scale (NRS), and Total Pain Rating Index (T-PRI) were administered. RESULTS:Oral lichen planus patients had statistically higher scores than the controls in the majority of the PSQI sub-items (p-values < 0.001**). Moreover, OLPs had higher scores in the HAM-D, HAM-A, NRS, and T-PRI (p-values < 0.001**). No differences in the PSQI sub-items' scores were found between the K-OLPs and nK-OLPs, although nK-OLPs suffered from higher levels of anxiety, depression, and pain (p-values: HAM-A, 0.007**, HAM-D, 0.009**, NRS, <0.001**, T-PRI, <0.001**). The female gender, anxiety, depression (p-value: 0.007**, 0.001**, 0.020*) and the intensity of pain, anxiety, and depression (p-value: 0.006**, <0.001**, 0.014*) were independent predictors of poor sleep (PSQI > 5) in K-OLPs and nK-OLPs, respectively. The PSQI's validation demonstrated good internal consistency and reliability of both the total and subscale of the PSQI. CONCLUSIONS:The OLPs reported an overall impaired QoS, which seemed to be an independent parameter according to the regression analysis. Hence, clinicians should assess QoS in OLPs and treat sleep disturbances in order to improve OLPs management. 10.1111/jop.13255
