The economic cost of physical inactivity in China

ObjectiveTo estimate the total economic burden of physical inactivity in China. MethodThe costs of physical inactivity combine the medical and non-medical costs of five major Non Communicable Diseases (NCDs) associated with inactivity. The national data from the Chinese Behavioral Risk Factors Surveillance Surveys (2007) and the National Health Service Survey (2003) are used to compute population attributable risks (PARs) of inactivity for each major NCD. Costs specific to inactivity are obtained by multiplying each disease costs by the PAR for each NCD, by incorporating the inactivity effects through overweight and obesity. ResultsPhysical inactivity contributes between 12% and 19% to the risks associated with the five major NCDs in China, namely coronary heart disease, stroke, hypertension, cancer, and type 2 diabetes. Physical inactivity is imposing a substantial economic burden on the country, as it is responsible alone for more than 15% of the medical and non-medical yearly costs of the main NCDs in the country. ConclusionsThe high economic burden of physical inactivity implies the need to develop more programs and interventions that address this modifiable behavioral risk, in order to curb the rising NCDs epidemic in China.

Human Behaviors Determine Health: Strategic Thoughts on the Prevention of Chronic Non-communicable Diseases in China

In the last three decades, people's living standards have significantly increased along with the rapid growth of the national economy of China. However, the prevalence of unhealthy behaviors and unfavorable lifestyles (e.g., smoking, excessive use of alcohol, physical inactivity, and unhealthy diets) also steadily increased, which may contribute to the growing epidemic of chronic non-communicable diseases (CNCDs) such as diabetes, coronary heart disease, stroke, and cancers. To briefly summarize the major studies from China concerning epidemic and burden of CNCDs and unhealthy lifestyles, and propose intervention strategies toward unhealthy lifestyles and behaviors aiming for effective control of the growing epidemic of CNCDs in China. We first review the major national studies addressing the epidemic and burden of CNCDs and unhealthy behaviors in China. Then, we aim to develop the preventive strategies against the increasing epidemic of CNCDs by focusing on the intervention campaign toward health unfavorable behaviors and lifestyles. CNCDs have posed major challenges to public health and the ongoing reform of health care system in China. Unhealthy lifestyles and behaviors (e.g., smoking, excessive alcohol consumpsion, physical inactivity, and imbalanced diets) are responsible for the growing epidemic of CNCDs. Adherence to healthy behaviors and lifestyles is critical for maintaining physical and mental health. Active implementation of the population-wide intervention program of health education and promotion by targeting unhealthy behaviors and lifestyles may help to constrain the growing epidemic of CNCDs in China.

Trends in diet, nutritional status, and diet-related noncommunicable diseases in China and India: the economic costs of the nutrition transition.

Undernutrition is being rapidly reduced in India and China. In both countries the diet is shifting toward higher fat and lower carbohydrate content. Distinct features are high intakes of foods from animal sources and edible oils in China, and high intakes of dairy and added sugar in India. The proportion of overweight is increasing very rapidly in China among all adults; in India the shift is most pronounced among urban residents and high-income rural residents. Hypertension and stroke are relatively higher in China and adult-onset diabetes is relatively higher in India. Established economic techniques were used to measure and project the costs of undernutrition and diet-related noncommunicable diseases in 1995 and 2025. Current WHO mortality projections of diet-related noncommunicable diseases, dietary and body composition survey data, and national data sets of hospital costs for healthcare, are used for the economic analyses. In 1995, China's costs of undernutrition and costs of diet-related noncommunicable diseases were of similar magnitude, but there will be a rapid increase in the costs and prevalence of diet-related noncommunicable diseases by 2025. By contrast with China, India's costs of undernutrition will continue to decline, but undernutrition costs did surpass overnutrition diet-related noncommunicable disease costs in 1995. India's rapid increase in diet-related noncommunicable diseases and their costs projects similar economic costs of undernutrition and overnutrition by 2025.

Trends of Waist Circumference Distribution and Abdominal Adiposity among Chinese Adults, 1993‐2004

Waist circumference (WC) is a strong predictor of hypertension and other noncommunicable diseases in China. This study examines temporal trends in waist circumference and the prevalence of abdominal adiposity trends among Chinese adults aged 20–65 from 1993 to 2004. We use data of the China Health and Nutrition Survey collected in 1993, 1997, 2000 and 2004. Compared with 1993, the 2004 waist circumference distribution curves flattened and shifted rightwards in males and females. Mean waist circumference increased from 76.8cm to 82.8cm among males and from 75.1cm to 79.3cm among females. A gradient of increasing prevalence of abdominal obesity was also observed in males and females. Similar trends of increasing waist circumference and abdominal obesity were observed in underweight, normal weight, overweight and obesity subjects defined by WHO recommended cutoff points of body mass index (BMI). These results demonstrate the rapid increase in obesity, especially abdominal obesity, among Chinese adults. Primary prevention of abdominal obesity should be a major public health problem in China.

Trends in the distribution of body mass index among Chinese adults, aged 20–45 years (1989–2000)

To describe body mass index (BMI, in kg/m(2)) distribution patterns and trends among Chinese adults, aged 20-45 years (1989-2000). A descriptive, population-based study of BMI change. Chinese provinces (eight in 1989 and 1997; nine in 2000), representative of the household-based surveys (the China Health and Nutrition Survey, 1989-2000) using multistage, random cluster sampling, supplemented with annual household consumption survey data of the State Statistical Bureau (SSB). A total of 4527, 4507 and 4046 adults, aged 20-45 years, in 1989, 1997 and 2000, respectively. BMI (underweight: BMI<18.5 kg/m(2) and overweight: BMI>/=25 kg/m(2)). Percentile curves for BMI in 1989 and 2000 were constructed by gender and age using the LMS (lambda, mu, sigma) method. Compared with 1989, the 2000 BMI distribution curves flattened at higher levels of BMI (men and women). There was a 13.7% increase in the proportion of men and a 7.9% increase of women who were overweight or obese with a resulting greater change in the annualized prevalence rate for men. This increase in the prevalence of overweight and obesity was far greater than the decrease (2.1% for men; 2.2% for women) in that of underweight. Age-gender-specific percentile curves showed BMI increases mainly among women, aged 35-45 years, and among men at all age groups. Chinese BMI dynamics show much greater rates of change among men, aged 20-45 years, than among women, with the increase among women concentrated between ages 35 and 45 years. These changes portend large shifts in other diet-related non-communicable diseases in China over the following decades. Controlling the increasing trends of BMI, especially in men, is an important public health problem facing China.
