<p><b>OBJECTIVE</b>To evaluate the community-based health promotion effect of physical activity.</p><p><b>METHODS</b>The residents aged 18 and above from two communities in Gongshu District of Hangzhou City, Zhejiang province, were randomly selected and recruited for the multi-strategy and comprehensive physical activity intervention. Questionnaire survey, physical check up and blood biochemistry were conducted.</p><p><b>RESULTS</b>After this two-year intervention, the time of the participant spent on weekly physical activity of moderate intensity increased from 464 min to 542 min (P<0.05), with an average increase of 78 min. Time spent in walking every week increased from 533 min to 678 min (P<0.05), with an average increase of 145 min. The body weight, waistline, blood pressure and heart rate all reduced significantly (P<0.05); the vital capacity increased significantly (P<0.05); and the related biochemical indicators were also improved.</p><p><b>CONCLUSION</b>Comprehensive and evidence-based physical activity interventions targeting community population can improve the levels of physical activity, related body measurement and biochemical indicators.</p>

<p><b>OBJECTIVE</b>To study the effect of maternal nutrition status on child growth in China.</p><p><b>METHODS</b>The study was performed using data from 2002 China Nutrition Health Survey in which data were collected through stratified multi-stage cluster samples in 31 provinces, autonomous regions, and municipalities. Accroding to the height of women aged 18-44 y was 156.4 cm, the data on mother and children' weight and height/length (n = 1380) were analyzed.</p><p><b>RESULTS</b>The findings suggest child's length (age 2) were significantly correlated with maternal heights (P < 0.0001). The mean length in children born to mothers with a height below 156.4 cm was 2.4 cm less than those in children born to mothers with a height above 156.4 cm. The prevalence of stunting in children at age 2 born to mothers with a height below 156 cm was 2.07 times of that in children born to mothers with a height above 156 cm. Therefore, the risk for stunting in children at 2 is lower in children born to mothers with greater height.</p><p><b>CONCLUSION</b>The maternal nutrition status could have a significant influence on children physical development.</p>

<p><b>OBJECTIVE</b>To examine the association of dietary patterns with chronic diseases and their indicators.</p><p><b>METHODS</b>Using the data from 2002 National Nutrition and Health Survey, we divided the subjects into clusters according to their dietary patterns classified by different percentage of energy intake from cereal foods, carbohydrate and fat, respectively. The analysis of variance was used to identify the difference in chronic disease prevalence across clusters of subjects while controlling for age, gender and geographic regions. Logistic regression analysis was applied to calculate the odd ratios (OR) for association of chronic disease and each dietary pattern, after adjusted for age, gender, region, energy intake, leisure time.</p><p><b>RESULTS</b>The higher percentage of energy intake from cereals was significantly associated with lower body mass index (BMI), lower total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C). While it was significantly associated with lower risk for overweight/obesity, hypertension, high total cholesterol, high triglyceride (TG) and high LDL-C, but the prevalence of underweight was significantly higher in the cluster of subjects with cereal energy share more than 75%. The higher percentage of energy intake from fat was significantly associated with higher BMI, higher total cholesterol and higher LDL-C, which accordingly, was significantly associated with higher risk for overweight/obesity, hypertension, high total cholesterol, triglyceride and high LDL-C.</p><p><b>CONCLUSION</b>Our study confirmed the important role of dietary pattern in chronic disease control; in particular, appropriate percentage of energy intake from fat and cereals/carbohydrates are beneficial to control and prevention of chronic diseases.</p>

<p><b>OBJECTIVE</b>To examine the association between fetal nutritional status and overweight and obesity in their adulthood and to provide evidence for formulation of the strategy on preventing low birth weight.</p><p><b>METHODS</b>Using data from 2002 Nationwide Nutrition and Health Survey to set up a case-control method in order to compare body mass index(BMI), prevalence of overweight and obesity as well as to calculate odds ratio of overweight and obesity of case group compared with control group. Three case groups were selected from those who were born in 1959, 1960,1961 respectively, and the controls were those who were born in 1964.</p><p><b>RESULTS</b>The health consequence of being famines on adulthood was evident in women. Means of BMI in women were significantly higher in three case groups than that in control group(P<0.01). After adjustment on geographic regions, the prevalence of overweight in women was significantly higher in three case groups than that in control group(P< 0.01). The prevalence rates of obesity were significantly higher in 1959, 1960 groups than 1964 group(P< 0.05). The odds ratios of overweight of women in three case groups were 28.9% (95% CI:1.063-1.565), 37.2% (95% CI:1. 136-1.658) and 35.2% (95% CI: 1. 103-1.657) respectively, all higher than that in the control group. The odds ratios of obesity of women born in 1959, 1960 groups were 46.5% (95% CI: 1.088-1.972) and 39.6% (95% CI: 1.039- 1.876) respectively, higher than that in the 1964 group. However, such differences were not found in men.</p><p><b>CONCLUSION</b>Higher risks of overweight and obesity in women were caused by malnutrition during their fetal lives. A strategy on preventing low birth weight should be formulated by the government to prevent the chronic disease in adulthood.</p>

<p><b>OBJECTIVE</b>To describe the current situation and trends of mean weight and height of the Chinese people.</p><p><b>METHODS</b>Subjects of 71,971 households from 31 provinces were selected by stratified multi-stage cluster random sampling method. Height from 210 136 and weight from 202 749 subjects aged 2-79 years were used to describe their trends of development during 1992-2002. The height of children younger than 3 years of age was measured by infant height bed while the others were measured by metal height pole within 0.1 cm accuracy. Fasting body weight was measured to the nearest 0.1 kg.</p><p><b>RESULTS</b>Data on the mean height (cm) of Chinese children aged 2, 6, 11, 17 years were gathered which include: 1) in urban area: boys as 90.1 (2y), 118.4 (6y), 144.9 (11y), 170.2 (17y); girls as: 89.0 (2y), 117.0 (6y), 145.8 (11y), 158.6 (17y); 2) in rural area:boys as 87.6 (2y), 113.1 (6y), 139.2 (11y), 166.3 (17y) while girls as 86.2 (2y), 112.9 (6y), 140.0 (11y), 157.0 (17y). When compared to the results from 1992, the average height increased among all age groups. The values of increase among different groups aged 2-5 years were seen as: 3.6 cm of boys in urban and 3.0 cm of boys in rural areas while 3.8 cm of girls in urban and 3.0 cm of girls in rural areas. Among the aged 6-19 year groups, the average increasing values of height were 3.1 cm, 3.4 cm, 2.8 cm and 3.1 cm of city boys, rural boys, city girls and rural girls, respectively versus adults as 0.7 cm, 0.9 cm, 0.6 cm and 1.0 cm, respectively. The mean weight (kg) of Chinese children aged 2, 6, 11, 17 years were listed as below: boys in urban area: 13.5 (2y), 22.2 (6y), 37.4 (11y), 58.7 (17y); girls in urban area: 12.7 (2y), 21.2 (6y), 36.7 (11y), 51.9 (17y); boys in rural area: 12.8 (2y), 19.4 (6y), 31.9 (11y), 54.9 (17y); girls in rural area: 11.9 (2y), 18.7 (6y), 31.8 (11y), 51.2 (17y). The average weights of all age groups on 2002 were all higher than their same age counterparts in 1992. The average increasing values of weight among children aged 2-5 years were 1.0 kg, 0.6 kg, 0.8 kg and 0.5 kg for city boys, rural boys, city girls and rural girls, respectively. Among the aged 6-19 year groups, they were 2.0 kg, 1.5 kg, 1.4 kg and 1.1 kg, while among the adults aged 20-70 years, they were 3.2 kg, 3.0 kg, 1.6 kg and 2.9 kg, respectively.</p><p><b>CONCLUSION</b>Both mean weight and height had a remarkable increase and the physical status improved among all age groups for the last ten years.</p>
