HYDRATION STATUS AND NUTRITIONAL HEALTH: A CROSS-SECTIONAL STUDY EXAMINING ASSOCIATIONS AMONG ADULTS
Main Article Content

Abstract
Hydration plays a foundational role in physiological regulation, nutrient transport, and organ function, yet it remains underrepresented in nutritional health assessments. Recent literature suggests a strong link between hydration status and indicators of cognitive performance, dietary intake, and physical function, particularly among adults. However, limited cross-sectional studies have examined these associations in diverse populations.
Objectives:
To investigate the relationship between hydration status and nutritional health—specifically dietary quality, physical performance, and cognitive function—among adults aged 18–65 years, while accounting for sociodemographic and lifestyle factors.
Methods:
A cross-sectional study was conducted over six months (February–July 2024) in urban and peri-urban communities. A stratified random sample of 400 adults (aged 18–65) was assessed using both subjective and objective measures of hydration: the Hydration Status Questionnaire (HSQ), urine specific gravity, urine osmolality, and color scale. Dietary intake was captured through 24-hour recalls and a regionally adapted Food Frequency Questionnaire (FFQ). Physical performance was measured using handgrip strength and bioelectrical impedance analysis (BIA), while cognitive function was assessed using the Mini-Mental State Examination (MMSE). Sociodemographic and behavioral variables were collected via structured interviews. Data were analyzed using SPSS v27, applying multivariate regression to control for confounders.
