ABSTRACT
Objective@#To explore the association between dietary inflammatory index (DII) and metabolic syndrome (MetS) and its components among children aged 6-14 years in Beijing, so as to provide a reference for preventing MetS.@*Methods@#A cross sectional study was carried out in 2 086 records of 1 832 children from the 2017 and 2019 Nutrition and Health Surveillance in Primary and Secondary school students of Beijing (NHSPSB). Three day consecutive 24 hour dietary recalls combined with weighing household cooking oils and condiments were used to collect dietary intake and calculate DII. MetS was diagnosed according to "Definition and Suggestion on the Metabolic Syndrome of Chinese Children and Adolescent". The Generalized estimating equations (GEEs) models were used to analyze the association between DII and the presence of MetS and its components (abdominal obesity, high triglyceride, low high density lipoprotein cholesterol, hypertension, and hyperglycemia).@*Results@#The mean DII score was (1.64±1.07) for the included children. No significant association was found between DII scores and the likelihood of MetS (per 1 point increment: OR =1.16, 95% CI =0.92-1.48, P >0.05). In terms of the components of MetS, DII scores were positively associated with the odds of high triglyceride (per 1 point increment: OR =1.17, 95% CI =1.01-1.36, P <0.05). There was no statistically significant difference in the association among different age groups ( P >0.05). No significant associations were observed between DII and other MetS components( P >0.05).@*Conclusion@#DII scores may not be correlated with the risk of MetS, but proinflammatory diet might increase the risk of high triglyceride. DII score in childhood should be emphasized to identify and prevent MetS as soon as possible.
ABSTRACT
Objective@#To describe the current situation of leisure time physical activity, sedentary behavior, and sleep duration of children and adolescents aged 6-14 in Beijing, and provide a reference basis for guiding school age children to carry out reasonable physical activities and formulating effective intervention measures.@*Methods@#A multistage stratified cluster random sampling method was used to investigate the nutritional and health status of 3 460 students in the first,third,fifth and seventh grades. Through the questionnaire surveys, the basic information of children and families and the activity information of children physical activity, sedentary behavior, and sleep were collected and statistically analyzed.@*Results@#The results showed that the median time of children daily leisure time physical activity (LTPA) was 20.0 (8.6, 38.6) min, children in suburb areas (18.6 min) and seventh grade (14.3 min) had shorter LTPA time( Z/H =5.12，119.11， P <0.01). The average daily sleep duration of children was (8.71 ± 0.76) h, the proportion of school age children with insufficient sleep reached 54.7%. With an increase in grades, the incidence of insufficient sleep increased significantly ( χ 2=407.13， P <0.01). The median daily sedentary time of children was 195.7(145.0, 255.7 ) min, and 84.5% of children engaged in more than two hours of sedentary behavior every day. Urban (202.9 min) and obese children (210.4 min) had longer sedentary behavior time, and with the increase in grade, the daily sedentary behavior time of children gradually increased ( Z/H =5.04，14.83，637.98， P <0.01).@*Conclusion@#Children and adolescents aged 6-14 years in Beijing have less LTPA time, too much sedentary time, and insufficient sleep duration. Grade is an important factor affecting physical activity, sedentary behavior, and sleep duration of children, and body shape may be related to their sedentary behavior and sleep time.It is suggested that targeted policies should be adopted for children of different grades to increase their physical activity and reduce their sedentary behavior to promote their healthy development.
ABSTRACT
Objective@#To analyze the phenomenon of alcohol drinking among school-aged children in Beijing, and to provide a reference for making measures for possible preventive interventions.@*Methods@#Data were from the Beijing Students’ Nutrition and Health Surveillance among 3 776 school-aged children in Beijing in 2015. Prevalence, frequency and pattern of drinking, daily consumption of alcoholic drinks, as well as influencing factors were described.@*Results@#Drinking was found in 11.2% of school-aged children, the drinking differences of students of different genders, grades, areas were of statistical significance(χ2=8.49, 126.91, 18.36, P<0.01), and the average age of the 423 drinking students was (10.5±1.6)years old. 290 children reported alcohol drinking once or twice in the past 1 week, accounting for 68.6% of the drinking children. 93 children reported drinking for three to six times, accounting for 22.0%, 40 students reported drinking for more than 7 times. Blending wine(58.2%) ranked as the most preferred, followed by beer(33.3%).Drinking was more likely reported among school-aged children who were boys, in higher grade, living in suburbs of Beijing, while children whose parents were more likely to drink in the past month, or from family with lower income and lower education level were also more likely to drink(P<0.05).@*Conclusion@#Drinking among school-aged children in Beijing in the past 1 is common, but their drinking amount per day was relatively low. Drinking was influenced by age, gender, living place, family and other factors. It is recommended that non-alcoholic intervention should be carried out as soon as possible for them.
ABSTRACT
ABSTRACTCarthami flos, the dried floret of Carthamus tinctorius L., Asteraceae (safflower), has been widely used in traditional Chinese medicine to treat a broad range of ailments, such as coronary heart disease, angina pectoris, gynecologic disease, stroke, and hypertension. However, although several studies on Carthami flos have been done consecutively, the results are usually scattered across various documents. This review aims to provide up-to-date information on the traditional uses, pharmacology, clinical applications, and toxicology of Carthami flos in China and thereby to provide a basis for further investigation of its use to treat dissimilar diseases. Various ethnomedical uses of Carthami flos have been documented in many ancient Chinese books. Crude extracts and isolated compounds from Carthami flos show a broad range of pharmacological properties, such as protective effects on brain tissue, on osteoblasts, and in myocardial ischemia, as well as anti-inflammatory, antithrombotic, antitumor, and antidiabetic activities. To date, safflower and safflor yellow injections have been used to treat coronary heart disease, chronic pulmonary heart disease, cerebrovascular diseases, orthopedic diseases, and diabetes mellitus. Regarding the toxicology of Carthami flos, among the side effects that have been observed are allergic reaction, spermatogenetic failure, fatty liver, and nephrotoxicity.
