OBJECTIVE: This study aimed to describe frequency and quantity of total dairy consumption of Chinese children and adolescents and explore the associations between dairy consumption and nutrition status, including stunting, wasting, overweight, and obesity. METHODS: Participants included 28,250 children and adolescents aged 6-17 years old. A food frequency questionnaire (FFQ) including 100 kinds of food was used to collect information about frequency and quantity of dairy consumption. Determination of stunting was with a height cutoff value for age and gender, and determination for wasting, overweight, and obesity was with BMI for age and gender. RESULTS: Of the total sample, 36.1% of children aged 6-17 reported consuming dairy food more than once per day (⪖ 1/day). The average total dairy intake of all the participants was 126.7 g/day. For boys, dairy consumption had an inverse correlation with stunting and wasting after controlling for confounders. For girls, dairy consumption was negatively associated with stunting and obesity after controlling for confounders as above. CONCLUSION Dairy consumption in Chinese children and adolescents was relatively lower than that in developed countries, and was negatively associated with stunting and wasting for boys and with stunting and obesity for girls.

BACKGROUND: The aim of this study was to investigate the association between sleep duration and dizziness in a representative Korean population. METHODS: We analyzed data from the Korea National Health and Nutrition Examination Surveys (2010–2012). A total of 12,499 adults who completed otolaryngologic examinations were evaluated. RESULTS: Both men and women with severely short sleep duration (≤ 5 hours) and severely long sleep duration (≥ 9 hours) tended to have higher dizziness prevalence. However, the adjusted odds ratio (OR) for sleep duration was only significant in women with dizziness after adjusting for confounders. Compared to that in an optimal sleep group (6–8 hr/day), the OR (95% confidence interval) for dizziness prevalence after adjusting for age and health behaviors (body mass index, smoking habit, alcohol consumption, level of exercise, metabolic syndrome, and tinnitus) was 1.473 (1.194–1.818) for the severely short sleep group (≤ 5 hr/day) and 1.472 (1.078–2.009) for the severely long sleep group (≥ 9 hr/day) only in women. CONCLUSION: In the Korean population, dizziness was associated with shorter or longer sleep durations only among women. Further epidemiologic and experimental studies are necessary to clarify the impact of dizziness on sleep disorders.

OBJECTIVETo describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013).

METHODSThe study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census (2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression.

RESULTSThe results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas.

CONCLUSIONThe prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups.

Malnutrition is not a simple disease, which occurs in the condition when the body does not get the right amount of nutrients to maintain healthy tissues and organ functions. Malnutrition generally refers both to undernutrition and overnutrition, but usually it is used to refer solely to a deficiency of nutrition. Infants and young children are the most vulnerable because of their high nutritional requirements for growth and development. Growth is an important indicator of health and nutritional status of a child. Generally, underweight, studding and wasting are used as the indicators of malnutrition. In fact, a gain in height is a better indicator of the adequacy of a diet than a gain in weight. Rates of weight gain needs to accompany accelerated height gain to maintain normal body proportions (weight-for-height). Now therefore WHO recommends using weight-for-height as the indicator of malnutrition of epidemic intensity in communities and of nutritional condition evaluation, including treatment assessment. The assessment of nutritional status is commonly summarized by the mnemonic "ABCD," which stands for anthropometric measurement (A), biochemical or laboratory tests (B), clinical indicators (C) and dietary assessment (D). Children with malnutrition are required to ingest more than 30 essential nutrients including both functional, protective nutrients (type I) and growth nutrients (type II), in order to have a catch-up growth in weight and height.

PURPOSE: The aim of this study was to evaluate the prevalence of Benign Vocal Fold Lesion (polyp, cysts, nodules) and Leukoplakia in Korea. MATERIALS AND METHODS: The data from the 2008 to 2011 Korea National Health and Nutrition Examination Surveys, which were cross-sectional survey of the civilian noninstitutionalized population of South Korea. A survey team that included an otolaryngology residents, nurses, and interviewers moved with a mobile examination unit and performed laryngologic interviews and examinations of vocal folds using rigid telescopic laryngoscopy on survey participants over 19 years old (n=19636). RESULTS: Laryngoscopic examination revealed normal results in 19251 (98.04%) of those included in the survey. Abnormal laryngoscopic findings were observed in 1.96% of the population examined, and vocal cord nodules were the most common abnormal finding. The prevalence of vocal cord nodules was 0.99-1.72%, the prevalence of vocal cord polyps was 0.31-0.55%, the prevalence of vocal cysts was 0.04-0.17%, and the prevalence of vocal cord leukoplakia was 0.07-0.21%. There was no significant correlation of linear trend of prevalence by year, and there were no significant differences in prevalence between males and females. CONCLUSION: This is the first nationwide epidemiologic study to assess the prevalence of Benign Vocal Fold Lesion (polyp, cysts, nodules) and Leukoplakia by both the Korean Otolaryngologic Society and the Ministry of Health and Welfare. The results of this large epidemiologic study provide valuable information regarding the prevalence of voice disorders and the management of laryngologic diseases.

This article evaluates the overall current disease burden of North Korea through the recent databases of international organizations. It is notable that North Korea as a nation is exhibiting a relatively low burden from deaths and that there is greater burden from deaths caused by non-communicable diseases than from those caused by communicable diseases and malnutrition. However, the absolute magnitude of problems from communicable diseases like TB and from child malnutrition, which will increase the disease burden in the future, remains great. North Korea, which needs to handle both communicable and nutritional conditions, and non-communicable diseases, whose burden is ever more increasing in the nation, can now be understood as a country with the 'double-burden' of disease.

OBJECTIVETo describe the impact of the global economic crisis on the nutritional status of children in China during and after the crisis.

METHODSData from 1990 to 2010 were sourced from the National Food and Nutrition Surveillance System. Approximately 16 000 children under 5 years old were selected using a stratified random cluster method from 40 surveillance sites. Anthropometric and hemoglobin measurements for children under 5 were conducted. Nutritional status was determined according to WHO child growth standards.

RESULTSPrevalence of underweight and stunting in children under 5 had a downward trend. Underweight prevalence was close to normal (less than 5%), with prevalence of stunting 12.6% in 2009 and 12.1% in 2010 in rural areas. Prevalence of stunting in infants under 6 months and 6-12 months old in poorer rural areas increased from 5.7%-9.1% and 6.7%-12.5%, respectively, in 2008-2009. This trend also continued post-crisis in 2010. Prevalence of stunting in children left behind by mothers was 20%-30% higher than in children the same age in general and poorer rural areas. Prevalence of anemia in children did not change in rural areas, but prevalence of anemia in all age groups increased in poorer rural areas, especially in children under 24 months old. Level reached 30%-40% in 2009, and fluctuated in 2010.

CONCLUSIONThe nutritional status of children under 5 was comparatively stable during and after the global economic crisis, attributable to the Chinese government's policy response. The nutritional status in poorer rural areas fluctuated in response to the economic crisis and, thus, relevant action and intervention must be taken immediately to help the most vulnerable population in poorer rural areas. A proper national nutritional strategy for children under 2 years old, including nutrition supplementation for pregnant women and in-home fortification for complementary feeding, should be initiated.

OBJECTIVETo investigate and analyze the nutritional status of infants, preschool and primary school students, pregnant and lactating women in Wenchuan earthquake disaster area after 3 months.

METHODSIn August 2008, the nutritional and health status information of special population were collected and evaluated using the questionnaires, anthropometric and hemoglobin concentration measurements from four settlements of villages and towns in Mao and Mianzhu Country of Sichuan and Kang Country and Wudu District in Gansu provinces. A total of 236 infants aged below 36 months, 48 preschool children, 368 primary students, 32 pregnant women and 72 lactating women were investigated. Principal investigator indexes included the low body weight, growth retardation, anemia prevalence, two-week prevalence of diarrhea and respiratory disease, food intake and nutrition-related diseases, the percentage of patients morbidity of 36 months infants, preschool and primary school students; the prevalence of anemia, the prevalence of nutrition-related diseases of pregnant and lactating women.

RESULTSThe stunting prevalence was 14.6% (34/236) and the anemia prevalence was up to 40.1% (61/236) among infants younger than 36 months. Besides, the percentages of infants and young children suffered from the respiratory-infected disease and diarrhea within recent two weeks were 40.4% (95/236) and 30.2% (71/236) respectively. The percentage of low body weight of preschool children was 14.6% (7/48) and the growth retardation and anemia prevalence was 14.6% (7/48) and 39.6% (19/48), respectively. Among primary students, 6.3% (23/368) showed growth retardation and 12.2% (45/368) were anemia. The prevalence of anemia status of pregnant women and lactating mothers were 53.9% (17/32) and 24.4% (18/72) respectively. The main food composition of 45.8% (33/72) lactating women were grain and vegetables, 29 (40.3%), 32 (44.4%), 28 (38.9%) and 53 (73.6%) lactating women did not have animal originated (including meat, aquatic, livestock and poultry products) food, eggs, beans and their products, milk and dairy products, respectively.

CONCLUSIONSpecial population lived in disaster area have suffered different degree of malnutrition. The main dietary pattern was vegetable food. The consumption of meat, eggs, milk and milk products was relatively insufficient.

OBJECTIVETo assess the nutrition status of children and adolescents in China using the WHO growth reference (2007) in comparison with that defined by the International Obesity Task Force (IOTF) and the Working Group on Obesity in China (WGOC).

METHODSOverweight and obesity were defined by age-, sex-, specific BMI reference developed by WHO (2007), IOTF (2000), and WGOC (2004), respectively. Stunting and thinness were defined as height and BMI less than two standard deviations (SD) of the WHO growth reference (2007), respectively. Data of children and adolescents aged 5 to 19 years (n=54,857, 28,273 boys, 26,584 girls) from the 2002 China National Nutrition and Health Survey (CNNHS) were used in the study.

RESULTSThe prevalence of overweight, obesity, stunting and thinness among Chinese children and adolescents aged 5-19 years was 5.0%, 1.2%, 13.8%, and 7.4%, respectively when the WHO growth reference (2007) was used, whereas the estimated absolute total number affected by these 4 conditions were 14.6, 3.7, 40.6, and 21.8 million, respectively. The prevalence of overweight and obesity was 18.1% in large cities, while the stunting prevalence was 25.1% in rural 4. Obesity prevalence assessed by the WHO growth reference was higher than that as assessed by the IOTF reference, and obesity prevalence assessed by the WGOC reference was lower than that as assessed by the IOTF reference.

CONCLUSIONThe nutritional status of children and adolescents is not equal in different areas of China. Stunting is still the main health problem of the poor, while overweight and obesity are the main health problems in large cities.
