To assess the association between sleep period time and dietary patterns (DPs) in Brazilian schoolchildren aged 7-13 years.

Sleep data of 1019 children were obtained from a questionnaire completed by parents/guardians. Food consumption, physical activity, and screen-based activity were assessed through the validated Web-CAAFE questionnaire. Latent profile analysis was used to identify dietary patterns. Associations between sleep period time and dietary patterns were analyzed by multinomial logistic regression, and the average marginal effect of sleep period time on the probability of adherence to dietary patterns was determined.

Overall, 11.4% of children had inadequate sleep period time (<9h per day). Three mutually exclusive dietary patterns were identified "Monotonous" characterized by high consumption of pasta, instant pasta, sweets, and hamburgers/hot dog/pizza/salty snacks; "Traditional" characterized by high consumption of rice, vegetables, green leaves, beans, manioc flour, maize/potatoes, and meats; and "Dairy, bread, green leaves, maize/potatoes and sausage". The likelihood of adherence to the "Dairy, bread, green leaves, maize/potatoes and sausages" DP decreased by 0.026 as sleep period time increased by 1h per day. Olaparib inhibitor For a sleep period time of more than 10h per day, the average marginal effect of sleep period time on the likelihood of adherence to the this dietary pattern was significant and negative.

Sleep period time was inversely associated with adherence to the "Dairy, bread, green leaves, maize/potatoes and sausages" DP; children who slept more than 10h per day were less likely to present this pattern.

Childhood sleep problems have been associated with a number of negative health outcomes, but there is limited data on the relationship between sleep problems and social and emotional problems in preterm babies.

The aim of this study was to investigate sleep habits and the relationship between sleep problems and social and emotional problems in preterm infants with a corrected age of three years old.

The study included 40 preterm children and 40 full-term children. In order to evaluate the sleep habits and social and emotional problems of the children, their mothers completed the Brief Infant Sleep Questionnaire (BISQ) and the Brief Infant Toddler Social Emotional Assessment Scale (BITSEA) form.

It has been found that preterm children had longer sleeplessness at night than full-term children and the frequency of night awakening was also higher in full-term children. There was no difference between preterm and full-term children in terms of sleep duration, sleep location and methods of falling asleep. A. However, BITSEA competence scores were lower in preterm children and an association has been found between sleep behaviors and social and emotional problems.

Napping is a habit prevalent worldwide and occurs from an early age. However, the association between napping and the risk of incident cardiovascular disease (CVD) and all-cause mortality remains unclear.

We conducted a systematic search of Medline, Embase, and Cochrane databases from inception to December 2019 for cohort studies investigating the association between napping and the risk of incident CVD and/or all-cause mortality. Overall estimates were calculated using random-effect models with inverse variance weighting. Dose-response meta-analysis was performed using restricted cubic spline models.

A total of 313,651 participants (57.8% female, 38.9% took naps) from 20 cohort studies were included in the analysis. All-cause mortality was associated with napping overall (HR 1.19, 95% CI 1.12-1.26). Pooled analysis detected no association between daytime nap and incident CVD. However, in subgroup analysis including only participants who were female (HR 1.31, 95% CI 1.09-1.58), older (HR 1.36, 95% CI 1.07-1.72), or took a long nap (HR 1.34, 95% CI 1.05-1.63), napping was significantly associated with a higher risk of CVD. Dose-response analysis showed a J-curve relation between nap time and incident CVD. The HR decreased from 0 to 25min/day, followed by a sharp increase in the risk at longer times. A positive linear relationship between nap time and all-cause mortality was also observed.

Long napping was associated with increased risks of incident CVD and all-cause mortality. Further, large-scale studies and genetic studies need to confirm our conclusion and investigate the underlying mechanisms driving these associations.

To evaluate the presence of sleep disorders and its associations with exercise capacity and daily physical activity levels among children and adolescents with CF.

Children age 6-18 years with a diagnosis of CF were recruited. Information regarding sociodemographic profile, pulmonary function and nutritional status were collected. Sleep disorders (polysomnography), exercise capacity (modified shuttle test - MST) and daily physical activity levels (questionnaire and five days accelerometer use) were evaluated.

Thirty-one patients, median age of 9.6 years and forced expiratory volume in 1s (FEV

) of 68.1±24.4%, were included. Obstructive sleep apnea syndrome (OSAS) was present in 32.3% and nocturnal hypoxemia in 29%. The MST distance correlated with the mean peripheral oxyhemoglobin saturation (SpO

) during sleep (r=0.40) and the percent of total sleep time with SpO

<90% (r=-0.49). The final MST SpO

correlated with the occurrence of OSAS (r=-0.48) and mean nocturnal SpO

(r=0.45). Sedentary activities, as measured by accelerometry, correlated with sleep architecture, including the percent of stage II (r=0.60) and rapid eye movement (REM) stage sleep (r=-0.37). Patients with OSAS and nocturnal hypoxemia presented lower values (p<0.05) of distance and final SpO

in the MST. Nocturnal hypoxemia was the main variable to influence exercise capacity (r

=0.521).

Sleep disorders are distinctively related with exercise capacity and daily physical activity levels, as nocturnal hypoxemia is associated with exercise intolerance and sleep architecture disorders are associated with sedentary physical activity levels.
