Chrononutrition behaviors and cardiometabolic risk in adolescence: an ecological momentary assessment study.

Purpose: To investigate the potential associations between unhealthy chrononutrition behaviors (meal timing, frequency, and regularity) and their combined impact on cardiometabolic risk in adolescence.

Methods: Chrononutrition behaviors were assessed using a 7-day ecological momentary assessment (EMA). The unhealthy chrononutrition score (ranging from 0 to 8) was determined based on late meal timing, low meal frequency, and meal irregularity.

The association between outdoor artificial light at night exposure and antenatal depression and anxiety symptoms: A retrospective cohort study in China.

Background: Outdoor artificial light at night (ALAN) has emerged as a significant source of environmental pollution, however its association with antenatal depression and anxiety symptoms has been rarely explored before.

Methods: This study was based on a cohort study conducted at the Maternal and Child Health Care Center in Ma'anshan City, Anhui Province, China, which ultimately included 1047 pregnant women. Depression and anxiety symptoms were evaluated utilizing the self-administered Patient Health Questionnaire (PHQ-9) and the 7-item Generalized Anxiety Scale (GAD-7), respectively.

Sex-specific association between later circadian timing of food intake and adiposity among Chinese young adults living in real-world settings.

Timing of food intake is an emerging aspect of nutrition; however, there is a lack of research accurately assessing food timing in the context of the circadian system. The study aimed to investigate the relation between food timing relative to clock time and endogenous circadian timing with adiposity and further explore sex differences in these associations among 151 young adults aged 18-25 years. Participants wore wrist actigraphy and documented sleep and food schedules in real time for 7 consecutive days.

Association of Di(2-ethylhexyl) Phthalate Exposure with Reproductive Hormones in the General Population and the Susceptible Population: A Systematic Review and Meta-Analysis.

Di(2-ethylhexyl) phthalate (DEHP), an environmental endocrine disruptor, has hormone-like activity and endocrine-disrupting effects. However, the types of reproductive hormones associated with DEHP vary across the studies. Thus, we conducted a systematic review and meta-analysis to pool existing epidemiological evidence.

Associations between blue space exposure and rheumatoid arthritis: The modifying effect of genetic susceptibility and air pollutants.

Studies on the interaction among genetic susceptibility, blue space exposure, and rheumatoid arthritis (RA) risk have been lacking. Therefore, we examined the association between blue space exposure and RA incidence and assess the modifying effect of genetic susceptibility and air pollutants. Form the UK Biobank, 322,783 participants without RA were enrolled in this study.

Associations of Vitamin D With GPX4 and Iron Parameters in Chronic Obstructive Pulmonary Disease Patients: A Case-Control Study.

Vitamin D deficiency elevates the risk of chronic obstructive pulmonary disease (COPD) patients. Iron parameters elevation and glutathione peroxidase 4 (GPX4) reduction are involved in the process of COPD. The goal is to explore the associations of vitamin D with GPX4 and iron parameters in COPD patients through a case-control study.

Effects of PM and Its Components on Disease Severity in Patients with Schizophrenia and the Mediating Role of Thyroid Hormones.
