Journal of Preventive Medicine 2007;1(17):20-26
Background: many studies showed that obesity rate was significantly higher in women than in men and 60-80% of overweight/obesity caused by diet. Hanoi and Ho Chi Minh City were two of 10 provinces that had the highest rates of obesity. Objectives: to determine the actual rate of overweight/obesity and describe some related factors among Hanoians aged 50-59. Subjectives and Method: a cross sectional survey within a case-control study. The study was carried out in 14 wards under 7 districts of urban Hanoi. Body fat percentage was measured by machine Omron (Japan). Overweight/obesity evaluations were based on classification scales of WHO 1998 and IDI&WPRO 2000. Results: the mean rate of overweight/obesity was 23.1% (26.2% in women vs. 21.9% in men). The rate of women with waist to hip ratio >0.85 (39.83%) was higher than that in male (29.38%). Proportions of body fat percentage greater than 30% were 58.40% in female and 40.06% in male. Overweight/obesity was closely related with sedentary lifestyle, such as spending less time for exercise and sports, high food expenditures, etc. It was found that people with overweight or obese family members were 3 times at risk of overweight/obesity higher /than others. That rates of overweight/obese people with elevated level of biomarkers were composed of 48.99% with high blood cholesterol (>5.2mmol/l); 9.69% with blood glucose (\ufffd?.0mmol/l); especially 65.33% with high triglyceride (>1.7mmol/l); 7.22% with low HDL-C (<1.15 mmol/l); and 8.23% with high LDL-C (\ufffd?.00mmol/l). Conclusions: rate of overweight/obesity among Hanoians aged 50-59 was relatively high. Some related factors were described: waist to hip ratio, body fat percentage, sedentary lifestyle, such as spending less time for exercise and sports, high food expenditures, etc.

Objective: To explore the relationship between bisphenol A (BPA) exposure and obesity/overweight in children and adolescents through Dose-response Meta analysis. Methods: Articles published up to September 1st 2021 were systematically searched in PubMed, Web of science, Scopus, Embase, Cochrane library, CNKI, Wanfang databases and VIP Chinese Science and Technology Journal by using "bisphenol A" "BPA" "obesity" "weight" "fat""overweight" "body mass index" "BMI" "waist circumference" (both in English and in Chinese) as keywords. Use Stata 15.1 software to calculate the pooled OR (95%CI), perform heterogeneity test, subgroup analysis, sensitivity analysis, publication bias and the exposure-response relationship fitting. Results: A total of 9 English articles were included from 1 948 articles retrieved, including 8 articles from American and 1 article from China. 15 614 children/adolescents and 3 446 obese/overweight cases were further used for Meta-analysis of dose-response relationship. Meta-analysis results showed that there was heterogeneity among the highest dose groups in different studies(I2=52.1%, P=0.033). The random effect model-analysis found that compared with those in the lowest group, the OR(95%CI) for those in the highest group of urine BPA was 1.56(1.18-1.94)for the risk of obesity/overweight in children and adolescents, but there was no linear or nonlinear dose-response relationship. Sensitivity analyses showed that the results were robust, Egger's test(P=0.263) and Begg's test(P=0.348) showed that there was no publication bias. Conclusion: Bisphenol A exposure may increase the risk of obesity/overweight epidemics in children and adolescent.

BACKGROUNDThe metabolic syndrome is a clustering of metabolic abnormalities and has been associated with increased risk of type 2 diabetes mellitus and cardiovascular disease. This study aimed to estimate the prevalence of the metabolic syndrome among employees in Northeast China.
METHODSTotally, 33,149 employees who received health screening in the International Health Promotion Center in the First Hospital of Jilin University were enrolled. Height, weight, waist circumference, blood pressure, fasting plasma glucose, triglyceride, high-density lipoprotein, and low-density lipoprotein were recorded. Three definitions for the metabolic syndrome were applied, revised National Cholesterol Education Program's Adult Treatment Panel III (NCEP ATP III) criteria, the International Diabetes Federation (IDF) criteria, and the Chinese Diabetes Society (CDS) criteria.
RESULTSOverall, the age-standardized prevalence of the metabolic syndrome was 22.9%, 20.6%, and 15.3% based on definitions of revised NCEP ATP III criteria, the IDF criteria, and the CDS criteria, respectively. Men had higher age-standardized prevalence than women in all three definitions (P < 0.05). The prevalence was 27.1%, 24.5%, and 20.4% for men; 17.1%, 15.4%, and 8.3% for women, respectively. The most common metabolic component with the metabolic syndrome was overweight (54.7% of men had an elevated body mass index, and 35.9% of women had central obesity).
CONCLUSIONSA large proportion of employees among Northeast China have the metabolic syndrome. These findings place emphasis on the need to develop aggressive lifestyle modification for patients with the metabolic syndrome and population level strategies for the prevention, detection, and treatment of cardiovascular risk.

Objective: To analyze the association between body mass index (BMI) and coronary heart disease. Methods: The data for the present study were from the prospective cohort study of China Kadoorie Biobank (CKB) in Qingdao, a total of 33 355 participants aged 30-79 years were included in the study. Cox regression analyses were performed to evaluate the association between BMI and coronary heart disease. Results: During the follow-up for an average 9.2 years, a total of 2 712 cases of ischemic heart disease (IHD) and 420 cases of major coronary events (MCE) were found. Multivariate Cox regression analysis showed that, compared with participants with normal BMI, the participants who were overweight had a 41% and 87% higher risk of IHD and MCE, the adjusted HR were 1.41 (95%CI: 1.27-1.56) and 1.87 (95%CI: 1.43-2.44), respectively. The participants who were obesity had 91% and 143% higher risk of IHD and MCE, the adjusted HR were 1.91 (95%CI: 1.72-2.13) and 2.43 (95%CI: 1.82-3.24), respectively. Conclusion: Overweight and obesity might increase the risk for IHD and MCE.

OBJECTIVETo determine the current prevalence of overweight and obesity among children and adolescents (2-18 years) in Beijing and its distribution by age, gender and urban-rural residence.
METHODSAs part of the Beijing Child and Adolescent Metabolic Syndrome Study, a stratified cluster representative sample of 23,422 children aged 0-18 years was selected. Anthropometric measures including weight and height were collected from 21,198 subjects aged 2-18 years from April to October in 2004. Overweight and obesity were defined according to body mass index [BMI, weight(kg)/height(m2)] cutpoints. For national and international comparisons, three sex-age-specific BMI criteria were used:1) The BMI cutoffs recommended by the Chinese Working Group on Obesity for Children (WGOC) aged 7-18 years; 2) The US 2000 CDC Growth Charts (CDC 2000) frac 34, the 85th and 95th percentiles; 3) The International Obesity Task Force (IOTF) reference.
RESULTSThe overall combined prevalence of overweight and obesity was 18.6% with obesity as 8.1% based on the CDC 2000 criteria, The figures were 17.4% and 5.1% based on the IOTF criteria. According to the WGOC criteria, the combined prevalence of obesity was 20.9% and 8.9% in children aged 7-18 years. The combined prevalence was higher in school-age children (6-18 years) than in preschool-age children (19.8% vs. 14.8%, based on the CDC 2000 criteria). Among school-age children, the prevalence was higher in boys than in girls (26.7% vs. 16.5%), in urban than in rural areas (27.0% vs. 15.9%). However, these differences were not observed in preschool-age children. It was estimated that approximately 450 000 children from 2 through 18 years of age,were overweight or obesity in Beijing.
CONCLUSIONData from our study indicated that one fifth of the children and adolescents in Beijing were under overweight or obesity situation which was the highest in the nation. Obesity among children and adolescents in Beijing had already become a serious public health problem which deserved greater attention.

OBJECTIVETo analyze the current prevalence rates of overweight, obesity, central obesity and the clustering of major cardiovascular risks among middle-aged population of China.
METHODS1 000 participants aged 35-64 years in each of the 12 populations under study, were examined with international standardized criteria in 2009-2010. Out of the 11 623 potential respondents, 10 340 of them were eligible for analysis. Current prevalence rates of overweight, obesity and central obesity, and the clustering of major cardiovascular risks were analyzed. Overweight and obesity were defined under the Chinese BMI criteria.
RESULTSThe prevalence rates were 38.8% on overweight, 20.2% on obesity and 51.6% on central obesity, respectively. Overall, the prevalence was seen higher in females, in northern part of the country and in urban (P < 0.05). Participants with all of three risk factors (hypertension, diabetes and dyslipidemia) appeared 4.5 times in obese persons than in normal persons but 5.1 times in persons with central obesity.
CONCLUSIONAbout half of middle aged Chinese were under abnormal weight, and most participants in our study were accompanied with cardiovascular risk factors related to obesity. It is of urgent need to develop strategies on prevention and intervention against obesity.

OBJECTIVETo explore the association between early menarche with anthropometry measurements among adolescent girls in China.
METHODSResearch material was selected from the data of 2010 Chinese National Surveys on Students Constitution and Health. Probability unit regression method was used to calculate the age of 10th percentile (P 10) at menarche and menarche age before the P 10 was defined as early menarche(9.0-11.6 years old). A total of 1072 girls with early menarche were screened. Each girl with early menarche was frequency matched with two girls who hadn't achieved menarche and with the age difference less than 0.1 yr and from the same urban or rural locations. A total of 2144 girls without menarche were screened. Participants' data of height, weight, sitting height, chest circumference, body mass index(BMI) and height and sitting height index were analyzed. t test and wilcoxon test were used to analyze the anthropometry measurements differences between the two groups, Chi square test was used to analyze the differences of overweight and obesity between the two groups. Multilevel model was used to explore the association between early menarche with anthropometry measurements and overweight and obesity.
RESULTSA total of 1072 girls with early menarche and 2144 girls without menarche. Early menarche girls' height, sitting height, chest circumference, weight and BMI were (151.42 ± 7.46) cm, (80.86 ± 4.21) cm, (73.88 ± 7.72) cm, (44.32 ± 9.35) kg, and (19.18 ± 3.03) kg/m(2), while they were (144.86 ± 7.55) cm, (76.96 ± 4.05) cm, (67.25 ± 6.94) cm, (36.07 ± 7.88) kg and (16.64 ± 2.48) kg/m(2) in girls without menarche. The difference between two groups were significant(Z values were -22.20, -23.69, -24.38, -23.12, -20.17, -6.33 respectively with all P values < 0.01). Multilevel analysis results showed that in 9.0-11.6 years old girls early menarche was associated with anthropometry measurements(all P values < 0.05). Compared with girls without menarche, girls with early menarche had a relative higher height, sitting height, weight, chest circumference, with increments of 5.28 cm, 3.37 cm, 5.53 cm, 6.37 kg, 1.79 kg/m(2). Within subgroup analysis, there were parabolic trends with age in the height, weight and sitting height differences and "U" trend in chest circumference difference between girls with early menarche and girls without menarche.In 9.0-10.8 years old, 10.9-11.0 years old and 11.1-11.2 years old groups, the risk of overweight and obesity among girls with early menarche were 2.98 (95%CI:1.92-4.63) times, 6.76 (95%CI:2.79-16.39) times, 2.99 (95%CI:1.40-6.40) times of girls without menarche.
CONCLUSIONThe early onset of menarche is related with height, sitting height, weight and chest circumference, and it is closely associated with overweight and obesity among adolescent girls in China.
