INTRODUCTION Obesity is a serious public health problem that needs to be addressed urgently, because not only developed countries but also developing ones face an obesity epidemic among both children [...], BACKGROUND/OBJECTIVES: Dietary patterns represent the combined effects of foods and efficaciously illustrate the impact of diet on health outcomes. This study identified the dietary patterns and determined their relationships with obesity among young Chinese women. SUBJECTS/METHODS: In 2011, the China Health and Nutrition Survey included 2363 young women aged 18-44 years. Factor analysis of data from three consecutive 24-h dietary recalls identified the dietary patterns. Weight, height and waist circumstance (WC) were measured, and body mass index (BMI) was calculated. General obesity was defined as BMI [greater than or equal to] 28 kg/[m.sup.2] and abdominal obesity as WC [greater than or equal to] 85 cm. RESULTS: Four dietary patterns were identified: traditional south; traditional north; snack; and high protein. After adjusting for confounders and energy intake, women in the highest-score quintiles of the traditional south pattern were less likely to have general obesity (odds ratio (OR) = 0.48;95% confidence interval (CI) 0.29-0.78) and abdominal obesity (OR = 0.64;95% CI 0.46-0.90). Subjects in the highest-score quintiles of the traditional north pattern had significantly greater risk of general obesity (OR = 2.28; 95% CI 1.38-3.74) and of abdominal obesity (OR = 2.32;95% CI 1.66-3.24). CONCLUSION: The traditional south pattern of rice as the major staple food with pork and vegetable dishes is associated with lower risk of general and abdominal obesity. The traditional north pattern of high intake of wheat, other cereals and tubers is positively associated with general and abdominal obesity. This provides important information for interventions and policies addressing obesity prevention among young Chinese women. doi: 10.1038/ejcn.2015.8; published online 18 February 2015

INTRODUCTION Over the past two decades, there has been increasing concern over the role of total meat in chronic disease risks worldwide. (1-3) Recently, many studies in developed countries focused [...], BACKGROUND/OBJECTIVES: Several studies have suggested differential health effects in relation to different meat composition in Western population. The purpose of the study was to examine secular trends in meat and seafood consumption patterns among Chinese adults between 1991 and 2011. SUBJECTS/METHODS: Our longitudinal data are from 21 144 adults aged 18-75 in the China Health and Nutrition Survey, prospective cohort study. We assessed the intakes of meat and subtypes with three 24-h dietary recalls. We conducted multilevel mixed-effect logistic and linear regression models to examine meat consumption dynamics. RESULTS: The proportions of Chinese adults who consumed red meat, poultry and seafood increased from 65.7% in 1991 to 86.1% in 2011, from 7.5 to 20.9% and from 27.4 to 37.8%, respectively. With rapid decrease in meat intakes since 2009, the intakes of total meat, red meat, poultry and seafood among their consumers were 86.7 g/day, 86.4g/day, 71.0g/day and 70.3g/day in 2011, respectively, which were just slightly higher compared with those in 1991. Fatty fresh pork has been predominantly component of total meat overtime, which consituted 54.0% of total meat intake, 80.0% of fresh red meat intake and 98.7% of fatty fresh red meat intake in 2011. CONCLUSION: Over the past two decades, meat consumption patterns of Chinese adults have been characterized by having a predominant intake of fatty fresh pork, suboptimal intakes of seafood and increased proportion of adults having excessive intakes of red meat and poultry overtime.

INTRODUCTION Lots of available evidence indicate that consumption of foods with high dietary fiber (DF) has a broad range of potential health applications, (1) including in the treatment of colonic [...], BACKGROUND/OBJECTIVES: To analyze the time trends in total dietary fiber (DF) intake, DF food sources and total DF intake per 1000 kcal (DF density) in Chinese adults aged 45 years and above in the past 20 years. SUBJECTS/METHODS: We used the data from the China Health and Nutrition Survey (CHNS) collected in 1991, 1993, 1997, 2000, 2004, 2006, 2009 and 2011. Adults who were aged 45 years and above were included in each round. Water-insoluble DF intake was calculated by substituting the water-insoluble DF content of each food in the Chinese Food Composition Table (FCT) for food intake. Total DF was calculated according to the convert index, which indicates the ratio between total DF and water- insoluble DF for each food group. RESULTS: The mean daily total DF intake in males was 19.5 g/day in 1991 and 19.4 g/day in 2011. In females, it was 17.5 g/day in 1991 and 17.6 g/day in 2011. DF density increased in both males and females from 2004 to 2011. It was 9.0 g/1000 kcal in males and 9.5 g/1000 kcal in females in 2011. The major food sources of water-insoluble DF were cereals and vegetables. Communities with different levels of urbanization showed different trends in total DF intake: decreased consumption (2.9 g) in residents of low-urbanization communites and increased consumption (3.1 g) in those of high-urbanization communities. CONCLUSION: The average total DF intake in Chinese adults aged 45 years and above remained at a stable level. DF density increased because of slight decrease in energy intake. More public health messages should be disseminated, especially to the residents of low-urbanization communities, so as to increase their daily DF intake to a level close to the recommended DF intake.
