This study aims to analyze drinking habits, staying-up-late behavior, and unhealthy eating habits as risk factors for non-communicable diseases among communities in four regions of East Nusa Tenggara. A cross-sectional design was employed with 80 respondents. Data were collected using questionnaires and analyzed descriptively as well as spatially using QGIS and GeoDa. The results showed that inadequate water intake, high consumption of energy drinks, alcohol, coffee, and dietary supplements were most prevalent in Sumba and Alor. Unhealthy eating habits included excessive salty food consumption, frequent fast-food intake, and low fruit and vegetable consumption, with the highest prevalence found in Alor and Sumba. Additionally, 51% of respondents reported staying up late regularly, mostly 2–3 times per week, with the highest frequency in Sumba (79%) and Timor (55%). These lifestyle patterns contribute to an increased risk of non-communicable diseases such as hypertension, obesity, and metabolic disorders. This study highlights the need for community-based health education, campaigns to reduce risky beverage consumption, promotion of balanced nutrition, and initiatives encouraging healthy sleep patterns to mitigate future health risks.
