Objective:To evaluate the accuracy of parents ’ perception of whether their child is a picky eater and the specific food category the children avoideating according to the food frequency question-naire.Methods:This research selected 1 663 infants aged 4-36 months receiving non-diary complimen-tary food from maternal, infants, nutrition and growth study (MING Study) in 8 Chinese cities in which a combination of systematic cluster random sampling and purposive sampling was used .The general infor-mation, dietary status and picky eating status were collected through a self-designed questionnaire from the caregiver of the children .According to the parents ’ perception , the children were classified into picky/non-picky groups or avoid/non-avoid to a specific food category groups .Mann-Whitney U test was used to compare between the groups .Results: The reported percentage of picky eaters increased from 7.37%in 4-6 months old infants to 36.20%in 25-36 months old infants .Most picky infants in 4-6 months and 7-12 months old infants avoided eating dairy food ( 25% and 24%); while most picky toddlers aged 13-24 months and 25-36 months avoided eating vegetables (26.92% and 47.46%). The infants aged 4-6 months and 7-12 months who were perceived as picky by their parents took more kinds of food (8 and 19.5 kinds) than those who were not (6 and 18 kinds), while the picky toddlers aged 13-24 months and 25-36 months took fewer kinds of food (28.5 and 34 kinds for picky eaters, 31 and 37 kinds for non-picky eaters ) .The parents of infants aged 4-6 months judged correctly in every category of food without any statistical significance;the parents of 7-12 months old infants judged cor-rectly only in dairy food and eggs with statistical significance;those of 13-24 months old infants judged correctly in every food category except for vegetables with statistically significant difference in the category of eggs;those of 25-36 months old toddlers misjudged in dairy , beans and grains with no statistically significant difference in every category .Conclusion: Parents tend to misjudge their children ’ s picky eating behavior before the first 12 months of the child , and tend to make a more accurate perception after the 12th month.

Objective:To investigate the risk factors of proteinuria in patients with hypertension in Qinghai-Tibet Plateau.Methods:From March 2019 to June 2020, prospective design was used to collect data of Qinghai-Tibet Plateau hypertension patients who were eligible for continuous enrollment in the Department of Cardiovascular Medicine in Hospital of Chengdu Office of People's Government of Tibet Autonomous Region. Questionnaire survey, physical examination and blood pressure measurement were performed on the selected patients. Fasting venous blood samples were collected for liver function test, blood lipid test, blood glucose test, and hemoglobin test, etc. Three times of morning urine samples were taken on different days, and urine protein creatinine ratio (UACR) was measured, UACR < 30 mg/g was negative for urinary protein, and UACR≥30 mg/g was positive for urinary protein. At the same time, the selected patients were examined by carotid artery color ultrasound and heart color ultrasound. The risk factors of proteinuria were analyzed.Results:A total of 588 patients with hypertension met the inclusion criteria, including 472 patients (80.3%) who received antihypertensive drug therapy, 239 patients (40.6%) had antihypertensive treatment compliance, and 252 patients (42.9%) reached the standard blood pressure after theropy. Hypertension was associated with diabetes mellitus in 150 patients (25.5%), and urinary protein was positive in 126 patients (21.4%). In univariate analysis, ethnic composition, systolic blood pressure [(138.19 ± 19.65) vs (133.16 ± 18.45) mmHg, 1 mmHg = 0.133 kPa], diastolic blood pressure [(85.80 ± 13.51) vs (83.17 ± 12.19) mmHg], uric acid [(411.79 ± 101.54) vs (379.96 ± 102.18) μmol/L], hemoglobin [(152.86 ± 30.70) vs (143.49 ± 21.15) g/L], pulmonary artery trunk width [(21.76 ± 3.94) vs (20.98 ± 3.34) mm], and ventricular septal thickness [(9.90 ± 1.70) vs (9.47 ± 1.60) mm] in the positive group ( n = 126) were significantly higher than those in the negative group ( n = 462, P < 0.01 or < 0.05). In multivariate logistic regression analysis, increased systolic blood pressure [odds ratio ( OR) = 1.015, 95% confidence interval (95% CI): 1.005 - 1.026], uric acid ( OR = 1.003, 95% CI: 1.001 - 1.005), and pulmonary artery trunk width ( OR = 1.058, 95% CI: 1.001 - 1.118) were risk factors for proteinuria; Tibetans had a decreased risk of proteinuria compared with Han ( OR = 0.505, 95% CI: 0.317 - 0.805), but increased hemoglobin had an increased risk of proteinuria compared with normal hemoglobin ( OR = 1.890, 95% CI: 1.231 - 2.903). Conclusion:In patients with hypertension at high altitude, increased hemoglobin, systolic blood pressure, uric acid, pulmonary artery trunk width, and Han nationality are risk factors for proteinuria.
