FACTORS ASSOCIATED WITH PAROXYSMAL VERTIGO AMONG URBAN-DWELLERS AGED 55 YEARS AND OVER IN THE MALAYSIAN ELDERS LONGITUDINAL RESEARCH (MELOR) STUDY Background: Paroxysmal Vertigo (PV) negatively affects life quality and increases in prevalence with age, but the risk factors remain inconclusive. Objective: The present study aimed to investigate the risk factors of PV among a multi-ethnic urban population in late mid-life and late life within a middle-income Southeast-Asian country. Methods: Cross-sectional data from the first wave of the Malaysian Elders Longitudinal Research (MELoR) study were utilized for this study involving randomly sampled participants aged 55 years and over. Socio-demographics, comorbidities, and psychological status were obtained through home-based computer-assisted interviews. Results: Based on an analysis of 1530 participants, mean age (SD) = 68.81 (7.49), 64.9% female; 32.9% Malay, 34.6% Chinese), the lifetime prevalence of PV was 12.1%. The risk factors associated based on multivariate analysis were hypertension, osteoarthritis, depression, and vitamin B12 Deficiency. Chinese ethnicity (OR = 0.582; 95% CI = 0.390 to 0.870) and smoking (OR = 0.377; 95% CI = 0.223 to 0.637) were protective factors against PV. Conclusions: While the risk factors reported are similar to other studies, the lower prevalence of PV among ethnic Chinese and smokers had not previously been reported. Our study highlighted potential genetic and lifestyle links to PV which should be evaluated in future studies.

Mind-body therapies (MBTs) such as mindfulness, yoga, qigong, tai chi, meditation, and many more have become very popular in the last few decades as useful tools to reduce stress and improve health. These methods are non- invasive and cost-effective. There are several reports that infer MBT can modulate the host immune system in many diseases. Although there are some discrepancies in the reported effects, the majority imply favourable effects of MBTs. This review summarizes the effects of MBTs in various chronic disease including cardiorespiratory conditions, metabolic diseases, cancer, HIV, gastrointestinal diseases, and depression. The results from most studies show that MBT reduced stress and anxiety; whilst improving sleep and overall quality of life. These observations were coupled with a decrease in cortisol level, an increase in glucocorticoid receptors, modulation of the autonomic nervous system, and changes in oxidative stress pathways, which may have resulted in improved immune functions. Furthermore, interactions between different parts of the brain such as the limbic system and hypothalamus upon exposure to MBTs can lead to reduced sympathetic nervous system outflow, which can improve the function of different organ systems resulting in the favourable host immunological responses observed in these studies.
