Quality of biological night-time regeneration and socioeconomic factors, health behaviors and body composition among middle-aged women: a cross-sectional pilot study

Background: Sleep has both immediate and long-term impacts on health. Aim of the study: This study aimed to evaluate the relationship between the quality of biological night-time regeneration, socio-economic status, health behaviors, nutritional status, and fat tissue distribution among adult women (n=46, aged 45-65 years). Material and methods: Socio-economic and lifestyle data were collected through a questionnaire, while anthropometric measurements were obtained using standard instruments. Statistical analyses were performed using the STATISTICA software package. Results: The study found no significant associations between socio-economic status, and the frequency of well-slept (participants satisfied with night-time regeneration) or sleep-deprived (respondents dissatisfied with night-time regeneration) individuals. However, an increased frequency of beer consumption was associated with dissatisfaction with night-time regeneration. There was no significant relationship between BMI categories and fat distribution types in relation to self-reported sleep sufficiency. Nonetheless, the analysis indicated that both BMI and WHR were higher in women who reported dissatisfaction with night-time regeneration compared to those who reported satisfaction. The trends suggest that women with higher education, white-collar occupations, residing in large cities, and consuming weak alcoholic beverages reported poorer sleep quality more frequently. This pattern is associated with a higher risk of excessive weight and central fat distribution, potentially due to increased psychosocial stress. Conclusions: Further research is necessary to verify these trends and elucidate the underlying mechanisms.
