Chronic sleep deprivation and inadequate eating habits have been associated with an increased
risk of developing various acute and chronic diseases, negatively impacting overall health and
well-being. Relationship between Sleep Quality and Dietary Intake in Young Adults Attended at
the Hospital General de Luque, 2025. This study aimed to determine the relationship between
sleep quality and dietary intake in young adults attending the Hospital General de Luque during
2025. An observational, descriptive, and correlational study with a quantitative approach
was conducted on a sample of 127 adults aged 18 to 30 years. Data were collected using
the Pittsburgh Sleep Quality Index (PSQI) to assess sleep quality and a 24-hour dietary recall
to determine nutrient intake. Results showed that 65% of participants had poor sleep quality,
characterized by daytime sleepiness, nocturnal awakenings, and prolonged sleep latency. A
high consumption of ultra-processed foods and sugary beverages was observed, along with low
intake of fruits, vegetables, and tryptophan-rich foods. Statistical analysis revealed a significant
association (p<0.05) between fruit and vegetable intake and better sleep quality. It is concluded
that poor sleep quality in this population is linked to inadequate dietary habits, highlighting the
need to implement hospital-based educational interventions to promote balanced nutrition and
good sleep hygiene.
