Correlation analysis of middle school students' body mass index and dietary nutrition / 公共卫生与预防医学

Objective To explore the relationship between body mass index and dietary nutrition intake of middle school students. Methods Using stratified cluster sampling to select 1 000 middle school students in our city as the research object , of which 132 cases were over-recombination and 479 cases were the control group. Collect students’ basic information, dietary data and lifestyle information through questionnaire surveys, analyze and compare the energy and nutrient intake of the two groups of students ; use a multivariate Logistic regression model to analyze the relationship between children’s energy intake and dietary patterns and obesity. Results Among 1 000 middle school students, obese men accounted for 24.4%, women obese 23.5%, the gender difference was not significant (P>0.05); 11-13 years old obese accounted for 18.9%, 14-16 years old obese accounted for 29.0 %, the older the age, the higher the obesity rate (P0.05). The weight, BMI, waist circumference, hip circumference, waist-to-hip ratio, diastolic blood pressure and body fat rate of the obese group (64.68±12.4kg, (27.54±2.46 ) kg/m2 , 98.43±9.14cm , 102.45±9.23cm, 0.98±0.08, 120.43±8.45mm Hg, 86.76±6.43mm Hg, (36.54±3.42)% are all compared with the normal group 42.56±8.45kg , (17.43±1.98) kg/m2, 69.43±7.5cm, 80.45±7.32cm, 0.86±0.08, 95.43±4.54 mm Hg, 67.43±4.32 mm Hg, (18.43±2.13)%the value is large (P<0.05); the normal group students have energy, protein, fat/energy, carbohydrate, sodium, Iron intake 1765.59±345.79Kcal, 57.43±15.38g, (50.32±15.47) %, 128.43±29.43g, 1419.34±153.98mg, 14.54±4.21mg were all compared with the obese group (2361.56±354.78Kcal, 81.57±22.76g) , (90.43±15.23)%, 163.89±24.62g, 1587.43±123.32mg, 1.73±0.51mg) low (P<0.05); the intake of energy, carbohydrates, protein, sodium and iron is positively correlated with the occurrence of obesity. Risk factors for obesity; and intake of vitamin C, vitamin E, potassium, calcium, and magnesium is negatively correlated with obesity and is a protective factor for obesity. Conclusion The overall weight control of middle school students in our city is not optimistic. Obese students have an imbalance in the intake of the three major nutrients and minerals, which will easily lead to obesity in the long run. The school and parents should work together to manage the student’s diet and exercise to ensure Student health.

The prevalence of gout and related factors in community population / 中华内分泌代谢杂志

Objective:To explore the prevalence of gout and related factors in community population, thereby provide evidence for comprehensive prevention and control of gout in community.Methods:A stratified multi-stage cluster sampling was used to survey the permanent residents of 20 to 75 years old in the 3 selected streets (towns), univariate analysis was performed using logistic regression by SPSS statistical software.Results:The prevalences of hyperuricemia and gout were 9.82% and 5.75% respectively(male 18.88% and 7.94%, female 3.79% and 4.29%)in Jiading Shanghai. The positive rate of family history was 17.13%, and the relationship between family history and gout was significant( OR=3.140, 95% CI 2.365-4.169, P<0.01). Age( OR=1.034, 95% CI 1.021-1.047), body mass index ( OR=1.102, 95% CI 1.074-1.131), waist-hip ratio ( OR=4.876, 95% CI 1.153-20.622), sleep quality ( OR=1.310, 95% CI 1.159-1.480), other animal meat ( OR=1.117, 95% CI 1.007-1.240), fresh water fish ( OR=1.138, 95% CI 1.005-1.288), and processed meat ( OR=1.145, 95% CI 1.033-1.270) were closely related to gout ( P<0.05 or P<0.01). Sex, alcohol drinking, marine fish, and soybean milk/soymilk were related to gout ( P<0.05 or P<0.01), but showed a protective effect ( OR<1.000). Conclusion:Reducing uric acid production through less consumption of purine-rich food such as animal meat as well as processed meat and weight control would be helpful in preventing gout.

Effect of dietary nutrition on tail fat deposition and evaluation of tail-related genes in fat-tailed sheep

BACKGROUND: The effects of dietary nutrition on tail fat deposition and the correlation between production performance and the Hh signaling pathway and OXCT1 were investigated in fat-tailed sheep. Tan sheep were fed different nutritional diets and the variances in tail length, width, thickness and tail weight as well as the mRNA expression of fat-related genes (C/EBPα, FAS, LPL, and HSL) were determined in the tail fat of sheep at three different growth stages based on their body weight. Furthermore, the correlations between tail phenotypes and the Hedgehog (Hh) signaling pathway components (IHH, PTCH1, SMO, and GLI1) and OXCT1 were investigated. RESULTS: C/EBPα, FAS, LPL, and HSL were expressed with differences in tail fat of sheep fed different nutritional diets at three different growth stages. The results of the two-way ANOVA showed the significant effect of nutrition, stage, and interaction on gene expression, except the between C/EBPα and growth stage. C/EBPα, FAS, and LPL were considerably correlated with the tail phenotypes. Furthermore, the results of the correlation analysis demonstrated a close relationship between the tail phenotypes and Hh signaling pathway and OXCT1. CONCLUSIONS: The present study demonstrated the gene-level role of dietary nutrition in promoting tail fat deposition and related tail fat-related genes. It provides a molecular basis by which nutritional balance and tail fat formation can be investigated and additional genes can be identified. The findings of the present study may help improve the production efficiency of fat-tailed sheep and identify crucial genes associated with tail fat deposition.

DIETARY INTAKES OF CAROTENOIDS IN CHINESE ADULTS FROM URBAN, SUBURBAN AND RURAL COMMUNITIES / 营养学报

Objective To explore the dietary intakes of carotenoids in Chinese adults.Method One hundred and eighty four 30-60 year-old adults(84 males and 100 females) from three different communities were recruited in the investigation.The dietary samples were collected by double-servings in every season of the year respectively.The double sample comprised all the foods of continuous 3 d at equal variety and quantity,and were analyzed by HPLC for the contents of ?-carotene,?-carotene,?-cryptoxanthin,lycopene,and lutein/zeaxanthin.Results The dietary samples were collected and analyzed from 184,184,169,and 161 subjects in summer,autumn,winter and spring respectively.The dietary intakes of ?-carotene,?-carotene,?-cryptoxanthin,lycopene,and lutein+zeaxanthin in the investigated subjects in summer were 2.48?2.71mg,276.6?469.4 ?g,86.9?241.4 ?g,2.16?3.38 mg,and 1.48?1.65 mg respectively.Those in autumn were 3.39?4.10 mg,271.7?462.8 ?g,339.9?1016.8 ?g,0.25?1.34 mg and 2.07?3.00 mg respectively.Those in winter were 2.85?3.76 mg,302.7?622.6 ?g,108.8?142.3 ?g,0.36?1.46 mg and 1.97?3.00 mg.and those in spring were 3.76?3.35 mg,162.4?413.9 ?g,42.1?93.8 ?g,0.86?1.39 mg and 6.10?6.26 mg respecfively.The lycopene intakes were relatively higher in summer,?-cryptoxanthin higher in autumn,and lutein/ zeaxanthin higher in spring.The intakes of ?-and ?-carotene were relatively less fluctuated by seasons.Generally,the subjects from the central urban community consumed more carotenoids than those from the outskirt community and the rural village,with the only exception of lutein/zeaxanthin intake in spring.Conclusion The dietary carotenoids intakes in Chinese adults were studied,and the data would be helpful for further researches about carotenoids nutrition among Chinese population.
