The prevalence of obesity is rising globally and in India. Overweight, obesity and related diseases need to be delineated in Asian Indian women. A literature search was done using key words like 'obesity', 'Asian Indian women', 'body fat distribution', 'type 2 diabetes', 'fertility', 'polycystic ovarian disease', metabolic syndrome', 'cardiovascular disease', 'non-alcoholic fatty liver disease', 'gender', 'sex' and 'prevalence' up to September 2012 in Pubmed and Google Scholar search engines. This review highlights the Asian Indian body composition with regards to obesity and provides a collated perspective of gender-specific prevalence of the co-morbidities. Recent data show that women (range of prevalence of overweight and obesity from different studies 15-61%) have higher prevalence of overweight and obesity as compared with men (range of prevalence of overweight and obesity from different studies 12-54%) in India and that obesity is increasing in the youth. The prevalence of overweight and obesity in both men and women steeply rose in a Punjabi community from Jaipur. Importantly, prevalence of abdominal obesity has been consistently higher in women than in men. The lowest prevalence (6.0%) of type 2 diabetes mellitus in women is reported from South India (rural Andhra Pradesh; 2006) and the highest (14.0%) by the National Urban Diabetes Survey (2001). Although the clustering of cardiovascular disease risk factors was generally high, it increased further in post-menopausal women. There are a number of factors that predispose Indian women to obesity; sedentary behaviour, imbalanced diets, sequential and additive postpartum weight gain and further decrease in physical activity during this period and cultural issues. In view of these data, preventive measures should be specifically targeted to Indian women.

Smart drug delivery system SDDS is a recently emerging therapeutic approach, now turning into a conventional model to deliver drug to specific sites or target. Drug targeted DT delivery systems maintain the concentration of the drugs at desirable doses in the body and avoid the need for repeated doses. The DT delivery system have specific distinguishing features such as self-regulated, pre-programmed, multitargeted, controlled by timely response, monitoring of the targeted drug delivery, responsive to pH, and spatially targeted. The DT delivery system exploits the biological membrane changes in the physiology of malignant cells to increase absorption or entry of drug-coated nanoparticles into targeted tissues. This system delivers a certain quantity of a therapeutic drug for longevity of its action to a targeted area within the human tissue, which in turn enhances efficacy of the treatment by reducing the side effects of drug administration. " new DT therapy strategy is a health improvement technique used in future generations for treatment of genetic diseases and intelligent drug delivery. The ultimate goal of SDDS is to administrate the drugs at the correct time with an exact dose in the body and with efficiency and specificity to the targeted cells that help the patients better adhere to their therapy regimen. The DT system enhances the maintenance of drug levels in targeted tissues and plasma without any destruction to the healthy tissues. This DT delivery system uses various strategies in targeting cells, drug delivery mechanisms, properties of targeted drug, organ-based targeted sites, disease, and drug-targeted vehicles. This chapter deals with all aspects of drug targeting and provides an overview of approaches in drug targeting, drug delivery vehicles, and strategies involved in successful delivery.
