GAMBARAN KUALITAS TIDUR DAN FUNGSI KOGNITIF PADA LANSIA DENGAN DIABETES MELLITUS DI KOTA BANDA ACEH


ABSTRAK
Lansia dengan Diabetes Mellitus (DM) rentan mengalami gangguan tidur dan penurunan fungsi kognitif. Gejala poliuria, polifagia dan polidipsia, terutama muncul pada malam hari sehingga berpotensi mengganggu kualitas tidur. Selain itu, gangguan metabolisme glukosa dan resistensi insulin dapat juga memengaruhi fungsi otak melalui gangguan perfusi serebral dan stres oksidatif, sehingga berkontribusi terhadap penurunan fungsi kognitif. Penelitian ini bertujuan untuk mengetahui gambaran kualitas tidur dan fungsi kognitif pada lansia dengan diabetes mellitus di Kota Banda Aceh, dengan desain penelitian deskriptif melalui pendekatan cross-sectional. Populasi penelitian adalah seluruh lansia DM di Kota Banda Aceh. Sampel berjumlah 278 lansia DM ditentukan dengan teknik accidental sampling, dengan kriteria eksklusi yaitu lansia yang mengalami demensia. Kualitas tidur diukur menggunakan Pittsburgh Sleep Quality Index (PSQI), sedangkan fungsi kognitif diukur menggunakan Saint Louis University Mental Status (SLUMS). Hasil penelitian menunjukkan bahwa sebagian besar lansia DM memiliki kualitas tidur baik (57,2%) dan gangguan kognitif ringan (61,5%). Kesimpulannya, penelitian ini menggambarkan bahwa lansia dengan DM di Kota Banda Aceh mengalami kualitas tidur baik dan penurunan fungsi kognitif ringan. Disarankan bagi tenaga kesehatan untuk edukasi mengenai sleep hygiene dan pengendalian kadar glukosa darah serta melakukan skrining kualitas tidur secara berkala guna mempertahankan kualitas tidur lansia. Selain itu, tenaga kesehatan juga diharapkan dapat melakukan skrining fungsi kognitif rutin, memberikan stimulasi kognitif, serta menganjurkan aktivitas fisik ringan untuk mempertahankan fungsi kognitif lansia.

MINISTRY OF HIGHER EDUCATION, SCIENCE AND TECHNOLOGY UNIVERSITAS SYIAH KUALA FACULTY OF NURSING UNDERGRADUATE THESIS January 26, 2026 XIV + VI Chapters + 100 Pages + 7 Tables + 3 Schemes + 16 Appendices Jannia Elsa 2212101010033 AN OVERVIEW OF SLEEP QUALITY AND COGNITIVE FUNCTION AMONG OLDER ADULTS WITH DIABETES MELLITUS IN BANDA ACEH ABSTRACT Older adults with Diabetes Mellitus (DM) are vulnerable to sleep disturbances and cognitive decline. Symptoms such as polyuria, polyphagia, and polydipsia, particularly occurring at night, may disrupt sleep quality. In addition, impaired glucose metabolism and insulin resistance may affect brain function through disturbances in cerebral perfusion and oxidative stress, thereby contributing to cognitive decline. This study aimed to describe sleep quality and cognitive function among older adults with diabetes mellitus in Banda Aceh using a descriptive cross-sectional design. The study population consisted of all older adults with DM in Banda Aceh. A total of 278 older adults with DM were selected using accidental sampling, with the exclusion criterion being older adults with dementia. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), while cognitive function was assessed using the Saint Louis University Mental Status (SLUMS) examination. The results showed that the majority of older adults with DM had good sleep quality (57.2%) and mild cognitive impairment (61.5%). In conclusion, this study indicates that older adults with DM in Banda Aceh generally experience good sleep quality and mild cognitive decline. Healthcare providers are advised to provide education on sleep hygiene and blood glucose control, as well as to conduct periodic screening of sleep quality to maintain sleep health among older adults. In addition, routine cognitive function screening, cognitive stimulation, and encouragement of light physical activity are recommended to help preserve cognitive function in older adults.
