Ageing is an irreversible process associated with numerous physiological alterations across multiple organ systems. It is determined by genetic and epigenetic background in addition to environmental factors associated with social structure, culture and lifestyle. Recently different studies have shown that calorie restriction (CR) plays a noticeable role in the path of delaying senescence by modulating epigenetic factors and metabolic pathways. CR elicits co-ordinated adaptive stress responses at the cellular and whole organism level by modulating epigenetic mechanisms (e.g., DNA methylation, histone modification and miRNA modification ), signaling pathways that regulate cell growth and ageing (e.g., TOR, AMPK, p53 and FOXO ) and cell-to cell signaling molecules (e.g., adiponectin ). Despite of this fact, CR appears to be one of the common ways to increase lifespan in all species. Nutrient sensing pathways are also considered as contributing factors in ageing process because several nutrients can activate different pathways directly or indirectly. Therefore, this review paper focuses on how the epigenetic factors can be influenced by CR during senescence.Keywords

Under nutrition, overweight and obesity of individuals who differ by age and sex are matters of great concern having social and health implications for countries around the world. According to NFHS report (1998-99), based on weight for height index (body mass index), more than one-third (36%) of women in Uttar Pradesh are undernourished. Health status of women is of great concern in the contemporary world, because of the multiple roles play by women given rise to serious health and nutritional problems. Women are, thus, vulnerable to malnutrition for social and biological reasons. A cross-sectional study was undertaken to determine anthropometric profile and nutritional status based on body mass index (BMI) of muslim females in Varanasi. A total of 220 females (aged 15-45years) residing in urban area of Varanasi was studied. Anthropometric profile including height, weight, waist circumference as well as BMI and waist-hip ratio (WHR) were measured. The main aim of the study was to determine their anthropometric characteristics and nutritional status through the assessment of Body Mass Index (BMI) and Waist-Hip ratio. It was found that 35.5%, 36.8%, 14.1% and 13.6% were under weight, normal, pre-obese (overweight) and obese, respectively on the basis of Asian BMI categorization. On the account of waist-hip ratio, 42.7% respondents were at high health risk whereas 57.3% were at low health risk. This study will provide baseline data for further studies on Muslim women in India and will help to plan and implement a comprehensive package for the management of their nutritional status.Keywords
