Relationship of Sunnah Fasting and DNA Damage Among Mild Cognitive Impairment (MCI) Older Adults

Abstract

Nutritional diet plays an important roles in the health of an individual. One of the simplest and suitable approach followed by certain individual especially older adults are Sunnah fasting. Sunnah fasting is reported to have a positive impact in maintaining public health and aids to prolong the life span of older adults. This study aimed to examine the relationship of Sunnah fasting in repairing DNA damage of older adults who suffer from mild cognitive impairment (MCI). The study design was comparative cross sectional study that comparing two phases (baseline and 36 months). A total of 99 subjects of MCI aged ≥ 60 years and have no terminally ill diseases involved in the study. Ten ml of whole blood, socio-demographic and cognitive assessment data was taken. The blood collected is used to determine DNA damage using the Alkaline Comet Assay. MMSE, IADL, ADL and GDS was conducted to determine the cognitive function. The study found that the percentage of DNA in tail (TD) for the subjects who practice Sunnah fasting for both phases is significantly lower than in subjects who did not practice Sunnah fasting (Baseline, TD: 12.49 ± 0.24% vs 17.40 ± 0.43%; 36 months, TD: 8.21 ± 0.43% vs 15.23 ± 1.16%). The percentage of tail moment (TM) for the subjects who practice Sunnah fasting for both phases is significantly lower than in subjects who did not practice Sunnah fasting (Baseline, TM: 0.92 ± 0.05% vs 1.46 ± 0.08%; 36 months, TM: 0.4 ± 0.03% vs 1.32 ± 0.13%). In conclusion, this shows the Sunnah fasting can reduce DNA damage among the older adult of MCI subjects. Thus, further research is warranted to determine the metabolomes in MCI subjects that related with Sunnah fasting to produce a predictive model of healthy diet to be used in the future.
