“…The incidence of overweight and obesity was lower than that reported in 2488 Chinese adults aged 20-45 years in seven provinces in China over an 8-year period from 1989 to 1997, where the number of overweight subjects (BMI X25 kg/m 2 ) almost tripled in men and doubled in women (Bell et al, 2001). Men in the Hong Kong study also had a higher incidence compared with women.…”

Objective: To examine dietary factors predisposing to overweight and obesity, taking into account age, gender, education level and physical activity. Design: Longitudinal population study. Setting: Community living subjects in Hong Kong. Subjects: One thousand and ten Chinese subjects participating in a territory wide dietary and cardiovascular risk factor prevalence survey in 1995-1996 were followed up for 5-9 years. Measurements: Body mass index (BMI) was measured. Information was collected on factors predisposing to development of overweight and obesity (age, gender, education level, physical activity, macronutrient intake, Mediterranean diet score and food variety), and the predisposing dietary factors examined, adjusted for other confounding factors, using logistic regression. Results: The 5-9-year incidence of overweight is 22.6% (BMI X23 kg/m 2 , 95% confidence interval (CI) ¼ 15.0-30.1%) or 11.5% (BMI X25 kg/m 2 , 95% CI ¼ 7.3-15.7%), and for obesity (BMI X30 kg/m 2 ) is 0.6% (95% CI ¼ À0.2-1.4%). The corresponding figures for women were 14.1% (95% CI ¼ 8.8-19.5%), 9.7% (95% CI ¼ 6.0-13.4%) and 3% (95% CI ¼ 1.3-4.8%). After adjusting for confounding factors (age, sex, education and physical activity), increased variety of snack consumption was associated with increased risk of developing overweight (BMI X23 kg/m 2 ) in the Hong Kong Chinese population over a 5-9-year period. Conclusion: Increased variety of snack consumption may predispose to weight gain over a 5-9-year period.

“…Varying patterns of change in weight status for Chinese children and adults are hypothesized to be influenced by biological differences in adults and children, variations in how children and adults are affected by environmental change and possible interaction between biological and environmental factors . Increases in the overweight prevalence among adults have been linked with decreases in work-and transport-related physical activity, while a relationship between overweight and a high-fat, low-fiber diet has been found for both children and adults (Paeratakul et al, 1998;Bell et al, 2001Bell et al, , 2002Wang et al, 2003). More research is needed in order to better understand the relationship between weight status changes for children and adults.…”

Under- and overnutrition dynamics in Chinese children and adults (1991–2004)

Objective: To examine trends in under-and overweight prevalence from 1991 to 2004 among adults and children in China by income and residence differentials. Methods/Subjects: Prevalence, average annual changes and annual relative changes in under-and overweight were determined. In 1991, 2848 children and 6806 adults were surveyed. The 2004 survey included 1566 children and 6172 adults. Results: Higher average annual reductions in underweight prevalence were found among children, particularly rural children, when compared with adults. With respect to income, low-income children and adults experienced the greatest average annual reductions in underweight prevalence. The trend for increased overweight was more pronounced than the trend for decreased underweight. Intensified trends were found among adults (versus children) and males (versus females). Relative to baseline prevalence, overweight increased fastest among adults in low-income and rural populations. Conclusions: Rapid increases in the overweight prevalence, particularly as found among low-income and rural Chinese adults, will likely lead to a shift in the burden of obesity-related chronic diseases toward the poor. Associated economic and health implications will further challenge the country's health care system, restrain economic development and widen existing disparities between the rural and urban as well as between the rich and poor populations of China.

“…Nonetheless, very high levels of overweight and obesity exist across the lower-and middle-income world and rates of increase are great (Mendez et al, 2005;Popkin, 2006;Popkin et al, 2006). This is certainly true in China, where there has been a recent and dramatic rise in the number of overweight adults in the recent past (Bell et al, 2001;Du et al, 2002). Further, rapid economic and social change has led to increased use of time-and laborsaving technologies, potentially reducing energy expenditure in both the home and occupational sectors (Popkin, 2003).…”

“…However, evidence from studies that have examined physical activity in the domestic and occupational spheres has shown these sources to be important (Weller and Corey, 1998;Evenson et al, 2003). In China, occupational activity has been shown to be the key modifiable determinant of weight gain (Bell et al, 2001). However, there is limited population-based, longitudinal research on weight and activity trends.…”

Objectives: To examine the longitudinal relationship between occupational and domestic sources of physical activity and body weight in a sample of Chinese adults. Methods: Population-based longitudinal observational study of Chinese adults (4697 women and 4708 men) aged 18-55 from the 1991, 1993, 1997, and 2000 waves of the China Health and Nutrition Survey. Measured height and weight and detailed self-reported energy expenditure from multiple occupational and domestic sources were assessed over a 9-year period. Longitudinal relationships were modeled using linear random effects models. Results: Increased occupational physical activity resulted in overall lower body weight for both men and women (b-coefficients (95% confidence interval (CI)) for high levels: À0.46 (À0.76, À0.15) for men, À0.36 (À0.62, À0.10) for women, and increased domestic physical activity resulted in overall lower body weight in men (b-coefficient (95% CI): À0.40 (À0.62, À0.18)). Conclusions: Physical activity that occurs in the occupational and domestic sectors is often overlooked; yet our research suggests they have important effects on body weight in Chinese adults. As China continues to urbanize, energy expenditure from these sources is decreasing, and our results point out the need to explore these types of physical activity more broadly across the world as potential sources of weight gain.

Weight gain and its predictors in Chinese adults

Abstract: The prevalence of overweight increased dramatically in this cohort. Light work-related physical activity was the strongest predictor of this weight gain.
