Westlake Personalized Nutrition and Health Cohort for Drug Addicts

2019-10-02 07:21:47 | BioPortfolio


This is a prospective cohort study of drug addicts confined in Zhejiang rehabilitation centers. The primary aim of this study is to investigate the association between diet and health status among drug addicts. The second aim is to characterize the continuous blood glucose response to dietary intakes over 2 weeks. The third aim is to describe the dynamic changes of gut microbiota at three time points in drug addicts during compulsory detoxification and to evaluate the association between gut microbiota, diet and addiction severity.


Over recent decades, there is a growing trend of drug addiction in China that poses great public health challenges. Drug abuse can lead to many health related problems such as malnutrition and mental disorders along with reduced quality of life. Dietary intervention plays a pivotal role in disease prevention and drug rehabilitation for drug addicts, but the associations between dietary intake and health related outcomes among drug addicts remain unclear.

In addition, the relationship between the human gut microbiota and its response to addictive drugs as a newly arisen subject is given wide attention in recent years. However, the underlying mechanism requires further investigation. The dynamic changes of gut microbiota among drug addicts during compulsory drug rehabilitation period are in vague.

Under the same diet exposure, different drug addicts may have different blood glucose responses as well as gut microbiota profiles. Therefore, in order to examine the association between diet, gut microbiota and drug addiction, our study design will include three components: (1) the measurement of dietary intake using FFQ while the menu offered by drug rehabilitation center and food diary; (2) the measurements of blood glucose over 2 weeks using continuous glucose monitors; and (3) the measurements of gut microbiota at three time points using 16s rRNA sequencing techniques.

A general state of sluggishness, listless, or uninterested, with being tired, and having difficulty concentrating and doing simple tasks. It may be related to DEPRESSION or DRUG ADDICTION.

A primary, chronic disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. The disease is often progressive and fatal.

Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers.

Diminished or failed response of an organism, disease or tissue to the intended effectiveness of a chemical or drug. It should be differentiated from DRUG TOLERANCE which is the progressive diminution of the susceptibility of a human or animal to the effects of a drug, as a result of continued administration.
