Improvement in cardio-metabolic health and immune signatures in old individuals using daily chores (Salat) as an intervention: A randomized crossover study in a little-studied population

Abstract

BackgroundDecline in cardio-metabolic health, immunity, and physical activity is associated with old age. Old people also find it difficult to engage in structured exercise programs. Therefore, there is a need to investigate common daily chores as an alternative for exercise that may also help in maintaining cardio-metabolic and immune health.ObjectiveWe aimed to investigate whether Salat, an obligatory Islamic prayer involving various physical movements and closely resembling yoga, enhances the benefits conferred by the current guidelines for physical activity.MethodsA total of 30 overweight adults (mean (SD) age of 53.5 (8.7) years) participated in this study. For a 4-week duration, we compared the effects of Salat before/after meals (Pre-MS/Post-MS) on selected immunological and metabolic parameters in serum samples. We also compared the effects of both Pre-MS/Post-MS regimens in young and old subjects to observe any age-related effects.ResultsMost of the baseline metabolic parameters and the count of immune cells were normal. Post-MS resulted in a significant reduction in body weight and percent body fat (%BF). Overall, Post-MS resulted in a clear leukocytosis with a significant increase in granulocytes, monocytes, and lymphocytes. When analyzing the lymphocyte compartment, a clear numerical increase was noted for T, B, and NK cells. The number of CD8+ T cells showed a statistically significant increase. Similarly, Post-MS induced leukocytosis in both young and old individuals, while the increase in granulocytes, monocytes, and lymphocytes was statistically significant in old subjects only.ConclusionThis study demonstrated that the Islamic obligatory and congressional Salat practice is capable of mimicking desirable pro-immune and pro-metabolic health effects.Clinical trial registration(UMIN000048901).

Nutritional Status of Pulmonary TB Patients in Pakistan– A Cross-Sectional Study from Mardan, Khyber Pakhtunkhwa

“…This alteration may be secondary to body fat composition. Body fat may be responsible for an inversion of the immune response from TH1 to TH2 subsets of CD4 T-cells with connection to cardiovascular health as well (Alam et al, 2022), and which could destabilize a latent infection by Mycobacterium tuberculosis, making the individual susceptible to the appearance of the disease. Pakistan population have previously been shown to have lower immunity profile in general (Alam et al, 2012(Alam et al, , 2013(Alam et al, , 2019Almajwal et al, 2020), a fact has a close relation with the disease severity and recovery form TB.…”

“…We sincerely thank Nutrition Education Awareness and Training (NEAT: Cooperative Society, Charsadda, KP) for its support in conducting this this study and the authors of some previous research work (Alam et al, 2022;Ali et al, 2023) for their technical assistance taken from their work.…”

Diets High in Energy, Protein, Zinc, Iron and Vitamin A and Their Effects on Body Weight in Patients with Tuberculosis

“…This shift can be related to how much fat the body has. The immune system's shift from TH1 to TH2 CD4 T-cell subsets, which is linked to cardiovascular health (Alam et al, 2022), may be triggered by excess body fat, which in turn may destabilize a latent infection by Mycobacterium tuberculosis and make the individual susceptible to the disease's manifestation. Lower immunity profiles have been seen in the Pakistani population in general (Alam et al, 2012(Alam et al, , 2013Almajwal et al, 2020), which is closely related to the severity of TB illness and the rate of recovery.…”
