| Introduction: Elderly individuals experience sleep-related problems, which have resulted in life dissatisfaction among them. Accordingly, the purpose of this research was to determine the effectiveness of magnesium supplementation on sleep quality and life satisfaction in elderly individuals. Materials and Methods: This study was a semi-experimental clinical trial with a pretest-posttest design and a control group. The study population consisted of all elderly individuals with sleep problems and poor sleep quality in Khomein city in 2024. The sample included 40 individuals who were selected through purposive sampling and were randomly assigned to two groups of 20 participants each. The research instruments included the Sleep Quality Questionnaire, Life Satisfaction Questionnaire, and a magnesium supplementation protocol, with the experimental group receiving magnesium treatment. Data analysis was conducted at two levels: descriptive statistics (mean and standard deviation) and inferential statistics (multivariate analysis of covariance). Results: The data analysis revealed that magnesium supplementation had significant effects on subjective sleep quality (F=12.83, p<0.01), sleep latency (F=73.04, p<0.01), sleep duration (F=13.45, p<0.01), overall sleep quality (F=34.56, p<0.01), daytime dysfunction (F=36.09, p<0.01), and life satisfaction (F=9.43, p<0.01). Conclusion: This study concluded that magnesium supplementation was effective in improving sleep quality and life satisfaction in elderly individuals, with the most significant effect observed in reducing sleep onset latency among the elderly participants. |
