Purpose:
This study aimed to investigate the potential influence of fish consumption on sleep disorders and their specific dimensions among adults in China.
Methods:
A cross-sectional study was conducted involving 904 participants aged 28-95 from Wenling, China. Fish intake was assessed using a Food Frequency Questionnaire containing 10 items. Sleep quality was evaluated using the Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI). Participants were categorized into three groups based on weekly fish intake. Logistic regression analyses were employed to determine the association between fish intake and the prevalence of sleep disorders and their specific dimensions.
Results:
Higher marine fish intake was negatively associated with PSQI subdimensions daytime dysfunction, sleep latency and sleep quality scores compared to lower fish intake (adjusted odds ratio (OR): 0.316, 95% confidence interval (CI): 0.205-0.486; adjusted OR: 0.462, 95% CI: 0.302-0.706; and adjusted OR: 0.568, 95% CI: 0.369-0.861, respectively). Marine fish consumption appears to have a positive association with sleep quality, as well as short sleep latency and daytime functioning, among adults in China.
Conclusions:
This study provides novel insights into the association between fish intake and sleep disorders and their specific dimensions.
