“…The proposed mechanisms linking physical activity with sleep are anxiety and depression reduction, promotion of lower body temperature at the onset of sleep and by a circadian phase-shifting effect. 9 The results of the present study and of some others 9,12,44 show that both sleep duration or quality and physical activity are related with obesity, and at least partly independent from each other.…”

“…Moreover, we were able to control for important variables, like mental health, OSA and physical activity, which were not assessed by Ko et al 43 Despite the above differences in the analytical design, the results in our study are in line with those reported by Ko et al 43 Earlier epidemiological studies on the association between sleep duration or quality and obesity in adults have used only BMI as the indicator of obesity. 12,16,44 We showed that the associations are rather similar, regardless of the chosen outcome (waist or BMI). The model predicting abdominal obesity was somewhat stronger than that predicting overall obesity, but this does not indicate that sleep disturbances per se would be better associated with abdominal obesity.…”

“…12,16,44 Only a couple of studies have shown a relationship between objectively measured indicators of self-reported sleep quality (for example increased sleep latency, lower proportion of Rapid Eye Movement (REM) sleep and frequent awakenings and increased nocturnal motor activity) and daytime tiredness in individuals with obesity and without OSA. 24,26,45 Compared to our study, the above studies used laboratory-based diagnosis of OSA or nocturnal breathing patterns.…”

Objective: To study relationships between obesity, physical inactivity and sleep-related disturbances (obstructive sleep apnea (OSA), sleep duration, sleep disturbances concomitant with daytime tiredness) in adults (X30 years). Design: Cross-sectional study with a random population sample. Participants: A total of 3377 men (mean age 52.3, s.d. 14.8, years) and 4264 women (56.4, s.d. 17.2, years). Main outcome measures: Dependent variables, measured: Waist circumference (WC) and body mass index (BMI). Independent variables, from a detailed interview/questionnaire: probable OSA, other sleep-related disturbances, sleep duration, type and frequency of leisure physical activity. Age, mental health, smoking and education were included in analyses as potential confounders. Results: In men, OSA and physical inactivity increased likelihood for abdominal obesity (WC X102 cm). Physical inactivity also increased, but long (X9 h/day) sleep decreased likelihood for abdominal overweight (WC: 94-101 cm) in men. In women, abdominal obesity (WC X88 cm) was associated positively with OSA, moderate sleep-related disturbances, and physical inactivity. Education modulated the influence of age on abdominal obesity in both genders. Using BMI as the dependent variable did not change the general information obtained by the model. In addition, abdominal obesity was found to be an independent risk factor also in multivariable models predicting categories of a combined sleep duration and sleep disturbances. Conclusions: Sleep duration and sleep-related disturbances are associated with obesity, even after controlling for OSA and physical inactivity. The results support the hypothesis of vicious circle between sleep and obesity.

“…Reciprocal relations among anxiety, distress, strain, depression and sleep disturbances have been suggested earlier [4,6,30,56]. These psychological symptoms are closely linked to obesity, smoking and physical inactivity [14,17,22,35,43,51,53], which have been suggested as risk factors for neck, shoulder and low back pains in adolescence [5,25,31,32,42]. Our findings that insufficient quantity or quality of sleep increases the risk of neck and low back pains independently of depressive mood, physical activity, sedentary behavior, smoking, BMI and parents' socioeconomic status may indicate that it has a mediating effect, explaining the relationship between social pressures, psychological symptoms and musculoskeletal pains.…”

Is insufficient quantity and quality of sleep a risk factor for neck, shoulder and low back pain? A longitudinal study among adolescents

et al. 2009

The quantity and quality of adolescents' sleep may have changed due to new technologies. At the same time, the prevalence of neck, shoulder and low back pain has increased. However, only a few studies have investigated insufficient quantity and quality of sleep as possible risk factors for musculoskeletal pain among adolescents. The aim of the study was to assess whether insufficient quantity and quality of sleep are risk factors for neck (NP), shoulder (SP) and low back pain (LBP). A 2-year followup survey among adolescents aged 15-19 years was (2001)(2002)(2003) carried out in a subcohort of the Northern Finland Birth Cohort 1986 (n = 1,773). The outcome measures were 6-month period prevalences of NP, SP and LBP. The quantity and quality of sleep were categorized into sufficient, intermediate or insufficient, based on average hours spent sleeping, and whether or not the subject suffered from nightmares, tiredness and sleeping problems. The odds ratios (OR) and 95% confidence intervals (CI) for having musculoskeletal pain were obtained through logistic regression analysis, adjusted for previously suggested risk factors and finally adjusted for specific pain status at 16 years. The 6-month period prevalences of neck, shoulder and low back pain were higher at the age of 18 than at 16 years. Insufficient quantity or quality of sleep at 16 years predicted NP in both girls (OR 4.4; CI 2.2-9.0) and boys (2.2; 1.2-4.1). Similarly, insufficient sleep at 16 years predicted LBP in both girls (2.9; 1.7-5.2) and boys (2.4; 1.3-4.5), but SP only in girls (2.3; 1.2-4.4). After adjustment for pain status, insufficient sleep at 16 years predicted significantly only NP (3.2; 1.5-6.7) and LBP (2.4; 1.3-4.3) in girls. Insufficient sleep quantity or quality was an independent risk factor for NP and LBP among girls. Future studies should test whether interventions aimed at improving sleep characteristics are effective in the prevention and treatment of musculoskeletal pain.

“…Accordingly, the activation of HPA axis by job stress is likely to cause sleep disorder. Second, psychosocial stress including job stress may cause unhealthy life habits such as drinking, smoking, and insufficient exercise and these life habits may work as factors disrupting sleep 39,40) . Third, mental disorder like depression is a representative factor that affects sleep 41) .…”
