AI Article Synopsis

  • Mental contrasting with implementation intentions (MCII) was tested to see if it could improve sleep outcomes compared to just providing sleep hygiene (SH) information.
  • The study involved 80 university employees who tracked their sleep and stress levels, finding that while overall sleep quality and duration improved, MCII didn't show a significant advantage over SH alone.
  • Higher stress was linked to poorer sleep quality and shorter sleep duration, suggesting that stress management might be key in improving sleep rather than simply using MCII techniques.

Article Abstract

Mental contrasting with implementation intentions (MCII) has been successfully applied to improve health-related behaviors (e.g. exercise). We explored its effectiveness to improve sleep outcomes beyond effects of sleep hygiene (SH) information, and investigated associations with stress. Eighty university employees (mean age: 29.6, SD = 4.5) were randomized to either a MCII + SH or a SH-only condition. During a baseline-week and a post-intervention week, sleep duration (Fitbit Alta and self-report), sleep quality, and stress were assessed daily and saliva was collected to assess the cortisol awakening response (CAR). In total, self-reported sleep quality and duration increased, but there was no meaningful condition*week interaction for sleep parameters or CAR. Higher average stress was associated with shorter sleep duration and lower sleep quality. Within-person, days with higher stress were followed by nights with lower sleep quality. Despite overall improvements, effects of MCII were not confirmed. MCII might be less effective to improve behaviors which are less controllable.

Introduction: It is reasonable to assume that lumbar spinal stenosis (LSS) affects the cauda nerve roots also at night.

Research Question: Does microsurgical decompression influence sleep quality and position?

Materials And Methods: A study nurse interviewed 140 patients scheduled for LSS decompression using the Pittsburgh Sleep Quality Index (PSQI), Spinal Stenosis Measure (SSM), Numeric Rating Scale (NRS) for back and leg pain, Douleur Neuropathique (DN4), and Charlson Comorbidity Index. Epidemiologic and MRI data were collected along with self-reported rankings of preferred sleep positions (prone, supine, side, and fetal).

The sleep disorder nocturnal enuresis (NE) affects children's health and quality of life, as well as places a heavy burden on their families. Treatment improves the child's quality of life. Unfortunately, some parents do not seek treatment for their children because they are unaware or misinformed about NE.

Social jetlag and diet quality among US young adults: interactions with race/ethnicity.

J Nutr Sci

August 2024

Sleep Disorders Center, Division of Sleep Medicine, Department of Neurology, Michigan Medicine, Ann Arbor, MI, USA.

The objective was to examine associations between social jetlag and diet quality among young adults in the US using nationally representative data from the 2017-2018 NHANES survey, and evaluate effect modification by gender and race/ethnicity. Social jetlag was considered ≥2-hour difference in sleep midpoint (median of bedtime and wake time) between weekends and weekdays. Diet quality was assessed with the Healthy Eating Index (HEI)-2015 and its 13 dietary components.

Background: Early establishment of energy balance related behaviors (EBRBs) may be effective in combating unhealthy lifestyle in preschoolers. Parents are responsible for cultivating preschoolers' EBRBs directly through parenting practices. Although investigating the impact of various parenting practices on preschoolers' EBRBs is crucial to determine which practices should be recommended to parents to help reverse childhood unhealthy lifestyle, it is important to assess whether these effects of parenting practices on preschoolers' EBRBs would be similar across different groups of preschoolers, necessitating research into the moderating effects of demographic characteristics.
