Objective To describe the exercise participation of residents in China,and to provide the scientific basis for developing intervention strategies.Method The data of 2002 China National Nutrition and Health Survey was used for the analysis.66 682 subjects(male 32 287,female 34 395) aged 6 years and above were involved.Results The overall rate of exercise participation of people in China was 15.7%,while that of urban residents(27.5%) was higher than that of the rural counterparts(11.1%).of all age-groups,18~years group had the lowest rate of exercise participation.8.0% people engaged in regular exercise while 7.7% people in occasional exercise.More urban residents(16.8%) engaged in regular exercise than their rural counterparts did(4.5%).The rates of regular exercise of residents in 6~years and 13~years groups were lower than those of occasional exercise,but the rates of regular exercise of people in 18~yrs,45~yrs and over 60~yrs groups were higher than those of occasional exercise.The types of exercise varied obviously among different age groups.Conclusion The rate of exercise participation of people in China is quite low.The guideline for physical activity of different target population in China should be developed in order to improve their participating rate of exercise and improve their health.

Objective: To analyze the drinking practice of people in China. Method: The data of 2002 China National Nutrition and Health Survey was used for this study. 159 117 subjects aged 15 years and over were involved. The information on drinking practice was collected using interview-administrated questionnaire. Results: The overall current drinking rate of people in China was 21.0%, 39.6% for male and 4.5% for female, respectively. The current drinking rates in urban and rural areas were 20.9% and 21.0%, respectively. The 45 to 59 years age group reached the highest. The rate of onset age of drinking younger than 18 years old was 8.8% in current drinkers. 39.9% male and 29.5% female current drinkers drank at least once a day. Distilled spirits was the first choice for 50.3% current drinkers. 58.2% male drinkers and 77.3% female drinkers consumed 100-150g and 50-100g distilled spirits, respectively. Conclusion: Alcohol drinking has become a public health problem in China, it is necessary to carry out further surveys to reveal the influencing factors.

Objective: To design the “one-year physical activity questionnaire” used in 2002 China National Nutrition and Health Survey. Methods: The intensity of each activity in the questionnaire was assessed from literature review and experts consultation. The energy intake was calculated from food frequency questionnaire for validation of the physical activity questionnaire. Results: The average daily energy expenditure per capita estimated from the questionnaire was 11.6MJ (male 11.9MJ, female 11.2MJ). The average physical activity level (PAL) was 1.95 (male 1.88, female 2.02). There was significant correlation between energy expenditure and energy intake (r = 0.13, P

Objective: To describe the physical activity level and its influencing factors of Chinese professionals, to provide basis for developing intervention strategies. Method: The information on physical activity was collected by one year physical activity questionnaire in "2002 China National Nutrition and Health Survey", and 29 783 professionals aged 18-59 years old(male 15 911, female 13 872)were involved. Metabolic equivalent (MET) was adopted to estimate the intensity level of physical activities. Physical activity level (PAL) was calculated to classify sufficient (PAL≥1.7) or insufficient (PAL

Objective:
To analyze the effect of breakfast nutrition quality on the satiety among young white-collar workers.
Methods:
A total of 278 subjects were recruited from two cities, Shenyang and Chongqing, in June 2015. The inclusion criteria: white-collar workers aged 25-45 years involved mainly in office work, who did not experience major changes, and individuals who should follow the study protocol and sign the informed consent form. The study employed a three-phase crossover design trial. Each participant received nutritional-adequate breakfast, nutritional-inadequate breakfast, and no breakfast treatment on the basis of assignment to one of three sequences. The breakfast time was once a week and then changed, all participants underwent the tests for three successive weeks. At last, we compared the effect of participants to consume different nutritional quality on satiety sense and hunger sense.
Results:
A total of 232 participants completed three successive breakfast intervention studies, the age of participants was (35.2 ± 7.9) years, comprised of 48.7% male (

Objective To analyze the iodine nutritional status of children and pregnant women in Liaoning Province,and the iodine content of edible salt suitable for iodine nutrition level,to provide a basis for adjusting the suitable salt iodine content standard of key population.Methods In 2015-2018,a cross-sectional survey method was used to conduct iodine nutritional status surveys in counties (districts) within the jurisdiction of Liaoning Province.One township (community) was selected in each county (district)according to the east,west,south,north,and middle directions.Forty children aged 8-10 (age and gender distribution balanced) and 20 pregnant women were selected in each township (community),urine and household salt samples were collected from children and pregnant women,to test urine and salt iodine levels;and the water samples from all township (community) water supply plants in the province were collected for water iodine detection in 2017;and all respondents were calculated the dietary iodine intake.The multi-order linear curve was used to fit the salt iodine content suitable for children and pregnant women.Results A total of 1 549 townships (communities) were surveyed,including 1 125 centralized water supply townships (communities) with water iodine < 40 μg/L;50 820 children aged 8-10 and 26 707 pregnant women were selected from the centralized water supply towns.The average iodine content of edible salt was 24.0 and 23.9 mg/kg,respectively.The median urinary iodine level of children was 168.5 μg/L,at the appropriate level of iodine;the median urinary iodine level of pregnant women was 137.8 μg/L,at the deficiency level of iodine.The average dietary intake of iodine in children was 228.4 μg/d,which was 3.51 times of the standard iodine requirement (EAR,65 μg/d) and 2.54 times of the recommended intake (RNI,90 μ g/d).The average dietary intake of iodine in pregnant women was 273.4 μg/d,which was 1.71 times of the EAR (160 μg/d) and 1.19 times of the RNI (230 μg/d),and 21.4% (5 728/26 707) of pregnant women had lower iodine intake than RNI,the iodine intake was insufficient.After multi-level linear curve fitting combined with monitoring data,the iodine content range of edible salt in children's urine was suitable and the iodine intake in RNI-tolerable intake (UL,300 μg/d) was 13-25 mg/kg (20 mg/kg + 20%);the iodine content range of edible salt in pregnant women's urinary iodine was suitable and the iodine intake in RNI-UL (600 μg/d) is 25-37 mg/kg (31 mg/kg + 20%).Conclusions Under the current salt iodine content standard (25 mg/kg) in Liaoning Province,children's iodine nutrition is generally at the level of iodine appropriate;pregnant women's iodine nutrition is generally at the level of iodine deficiency.It is recommended that all regions should revise the iodine content standard for edible salt in due course in combination with the iodine nutritional status of key populations within the jurisdiction.
