Knowledge, attitudes, and practices related to dietary salt among older adults in Abha, Saudi Arabia

The need to foster successful aging has intensified with the aging of the global population. This study aimed to assess the knowledge, attitudes, and practices (KAP) concerning dietary salt consumption and to investigate the correlations between sociodemographic variables and salt-related KAP. A structured interview was administered to a cohort of 200 older adults in Abha City, Saudi Arabia, recruited through a convenience sampling approach. The evaluation of salt-related KAP revealed widespread low knowledge (91.5%) as participants scored less than 3, negative attitudes (85.5%) scored less than 12, and predominantly unsatisfactory practices (69.5%) with scores less than 26. Noteworthy differences emerged between participants with poor overall KAP (81.5%) and those with good KAP (18.5%). Significantly weak negative correlations were found between age (r=-0.212), marital status (-0.236), and body mass index (-0.243) with overall KAP. Further examination revealed a significantly weak positive correlation between attitude and practice (r = 0.141). KAP scores show a highly significant positive correlation with overall KAP scores (r = 0.169, 0.352, 0.969). The uncovered correlations contribute to a valuable understanding of the complex dynamics surrounding salt-related KAP. This understanding guides the design of targeted interventions, such as health education programs, promoting successful aging and public health outcomes.
