Smoking set to kill one in three young men in China

Two-thirds of the young men in China start to smoke, mostly before age 20. A CKB led study published in The Lancet shows that around half of those who start smoking cigarettes as young men will eventually be killed by tobacco, unless they stop permanently. The results show that in China the annual number of tobacco deaths, mostly among men, had reached 1 million by 2010, and if current trends continue, it will be 2 million by 2030.

CKB Data now available worldwide

The CKB study group is committed to making the data collected/generated on the cohort available to the scientific community in China, the UK and worldwide and actively engages with collaborators on a range of projects. A CKB Data Access System was launched in September 2015 and, following a period of privileged access to China-based researchers, the CKB is pleased to announce that the resource is now open to all.

Breastfeeding may reduce a mother’s heart attack and stroke risk

A CKB report, published this week in the Journal of the American Heart Association, investigates breastfeeding patterns and the risk of maternal cardiovascular disease. It indicates that mothers who had breastfed had a lower risk of heart disease and a lower risk of sroke. The study provides further support for the World Health Organization’s recommendation that mothers should breastfeed their babies exclusively for their first six months of life.

Regular consumption of spicy foods linked to lower risk of death

A recent analysis of CKB data published in the British Medical Journal examines the association between the consumption of spicy foods and the total risk and causes of death. The research found that participants who ate spicy foods almost every day had a relative 14% lower risk of death compared to those who consumed spicy foods less than once a week.

Chinese adults with diabetes lose nine years of life.

In China, people with diabetes diagnosed in middle age lose, on average, nine years of life, according to new CKB research published in the January 17 issue of JAMA. This is mainly due to inadequate treatment, particularly in rural areas.

A large genetic study in Chinese adults showed no benefit of raising “good” cholesterol by CETP inhibition

Raising so-called “good” cholesterol by blocking a key protein involved in its metabolism does not protect against heart disease or stroke, according to a large genetic study of 150,000 Chinese adults published this week in JAMA Cardiology.

China Kadoorie Biobank

Chronic diseases (e.g. heart attack, stroke, diabetes, and cancer) are the leading causes of death and disability in developed and developing countries. Large blood-based prospective cohort studies can provide reliable assessment of the complex interplay of lifestyle, environmental, and genetic susceptibility as causes of chronic disease. Establishing such a study in China is of particular value, given the large size of its population, its increasing burden of chronic diseases, its unique patterns of disease rates and risk exposures, and the limited evidence from previous studies about the causes of many common chronic conditions in this population.

The China Kadoorie Biobank (CKB), known previously as the Kadoorie Study of Chronic Disease in China (KSCDC), is set up to investigate the main genetic and environmental causes of common chronic diseases in the Chinese population. During 2004-8, over 510,000 adults were recruited from 10 geographically defined regions of China, with extensive data collection by questionnaire and physical measurements, and with long-term storage of blood samples for future study. All the participants are now being closely monitored for death and other health-related outcomes through linkage with established registries and health insurance databases in the study areas. Every few years, periodic re-surveys are also to be conducted in about 25,000 surviving participants, with a repeat interview, measurements and blood collection (as in the baseline survey) to help assess changes of risk exposures in the study population. This large, well-established, study will be a uniquely powerful and rich resource for investigating the main causes of many common chronic diseases over the next few decades, and the information generated will advance our understanding of disease aetiology not only in China but also in other countries.

The CKB is being conducted jointly by University of Oxford’s Clinical Trial Service Unit & Epidemiological Studies Unit (CTSU) and the Chinese Academy of Medical Sciences (CAMS). It was established with funding support to CTSU from the Kadoorie Charitable Foundation (KCF) in Hong Kong. The long-term continuation of the study is supported by the Wellcome Trust, with further support in China from the Chinese Natural Science Foundation and Chinese Ministry of Science and Technology. The UK Medical Research Council (MRC), British Heart Foundation (BHF) and Cancer Research UK (CRUK) also provide core funding to CTSU for the project.
