Objective:To establish a reference interval for serum iodine of pregnant women with normal thyroid function and to analyze the relationship between serum iodine and thyroid disease risk.Methods:From July 2022 to October 2023, using cross-sectional survey method, pregnant women aged 18 to 48 years old who had lived in iodine-deficient areas in the six provinces of China (Shanxi Province, Fujian Province, Yunnan Province, Xinjiang Uygur Autonomous Region, Zhejiang Province, and Anhui Province) for more than six months were selected as the survey subjects. Blood samples were collected, serum iodine was tested, and the percentile method was used to establish a reference interval for serum iodine of pregnant women with normal thyroid function. Meanwhile, serum levels of free thyroxine, thyroid stimulating hormone, thyroglobulin antibody (TgAb), and thyroid peroxidase antibody (TPOAb) were tested, and logistic regression was used to analyze the relationship between serum iodine and thyroid disease risk.Results:A total of 1 409 pregnant women from 6 provinces were investigated, including 1 087 with normal thyroid function and 322 with abnormal thyroid function. The median serum iodine level of pregnant women with normal thyroid function was 79.74 μg/L, and the preliminary reference interval for serum iodine was 47.57 - 128.96 μg/L. When serum iodine levels were lower (< 47.57 μg/L), pregnant women had a significantly increased risk of developing TgAb positivity, TPOAb positivity, hypothyroxinemia, hypothyroidism, and autoimmune thyroiditis ( OR = 4.44, 2.91, 3.41, 41.67, 23.43, P < 0.05). When serum iodine levels were high (> 128.96 μg/L), pregnant women had a significantly increased risk of developing hyperthyroidism ( OR = 9.91, P = 0.001). Conclusions:The reference interval for serum iodine of pregnant women with normal thyroid function is successfully established. Low serum iodine levels are associated with an increased risk of TgAb positivity, TPOAb positivity, hypothyroxinemia, hypothyroidism, and autoimmune thyroiditis, while high serum iodine levels are associated with an increased risk of hyperthyroidism.

Objective: To explore the longitudinal associations between dietary macronutrients and lung function in schoolaged children, so as to provide the nutritional research evidence for promoting children s lung health. Methods: In November 2021, two primary schools located in Chengdu, Sichuan Province were selected from the Southwest China Childhood Nutrition and Growth (SCCNG) cohort by a stratified cluster random sampling method, enrolling a total of 1 112 school aged children aged 8 to 13 years. At baseline, the dietary and sociodemographic characteristics of the children were assessed. One year later, the forced vital capacity (FVC) of the children was measured and converted into Z scores (FVC- Z ), while the vital capacity index (VCI) was also calculated. Generalized linear regression analysis was employed to examine the associations between dietary macronutrients and lung function, considering interactions with gender and age, followed by stratified analysis. Results: After adjusting for confounding factors, the analysis results of the generalized linear regression model showed that the carbohydrate energy ratio was negatively correlated with FVC- Z ( β =-0.02) and VCI ( β =-0.16), while the fat energy ratio showed a positive correlation with FVC- Z ( β =0.03) and VCI ( β =0.23) ( P <0.05). The protein energy ratio was positively correlated with FVC- Z ( β =0.09) and VCI ( β =0.60) specifically in girls ( P <0.05). Additionally, there was an interaction effect of age on the associations between macronutrients and lung function ( P <0.01); in children aged 8-9 and 10-11, the carbohydrate energy supply ratio was negatively correlated with FVC- Z ( β =-0.04, -0.03) and VCI ( β =-0.29, -0.21), and fat energy supply ratio was positively correlated with FVC- Z ( β =0.07, 0.05) and VCI ( β =0.46, 0.32) ( P <0.05). Conclusions There are age and sex differences in the association of dietary macronutrients with lung function, with a low carbohydrate, high fat diet promoting lung function in children. Additionally, protein intake appears to have a positive influence on the lung function of girls. The early school age period may represent a critical window for dietary interventions aimed at promoting lung health.

Objective To explore the relevant relationship and specificity between the implicit and explicit loyalty of military cadets in order to provide a theoretical basis and objective indicators for a more comprehensive and objective assessment for individual loyalty.Methods E-Prime 2.0,a classic implicit association paradigm was employed to construct an implicit association loyalty test for 64 military cadets.Simultaneously,an explicit loyalty measurement was conducted using the Chinese Military Personnel Loyalty Scale.Results ① Significant implicit effect was observed in the loyalty assessment of military cadets,indicating a general tendency to perceive higher levels of personal loyalty and lower levels of loyalty to external entities.② Explicit loyalty assessment revealed that the participants had the highest loyalty score towards the Party,the Nation,and the People(4.79±0.34),followed by the loyalty score to their profession(4.38±0.53),and the relatively lower loyalty score towards the unit and leaders(4.03±0.83).Among the 3 dimensions of loyalty,the normative loyalty score ranked highest,while continuance loyalty score took lower.③ There were no correlations among the scores of loyalty to the Party,the Nation,and the People(r=-0.030,P=0.823),to the profession(r=-0.047,P=0.728),to the unit(r=0.050,P=0.710),or to the leaders(r=0.043,P=0.749).Conclusion The implicit effect in the loyalty assessment is significant in military cadets,and there is no significant correlation between explicit and implicit loyalty measurements.Thus,we cannot rely solely on explicit measurements to assess their loyalty attitudes.

In recent years, the high temperature and heatwaves have seriously affected the health of Chinese residents, and there is an important need for public health protection guidelines for high temperature and heatwaves in China. The National Bureau of Disease Control and Prevention has organized experts to fully investigate the evidence from epidemiological research on the health of populations in high temperature and heatwaves globally and in China, analyze the health hazards and protection needs of different populations, and put forward practical and effective individual protection measures and health recommendations. For this reason, the "Guideline for Public Health Protection against High Temperature and Heatwaves" (referred to as the "Guideline") was officially issued in June 2023. This article interprets the background and significance of the Guideline, the principles of compilation, the main considerations, the main contents, the implementations and promotions and other aspects, to improve the understanding of the content of the Guideline and strengthen the publicity and implementations.

Objective: To investigate the prospective effects of intake of each food group on the development of lung function of pupils,so as to provide theoretical basis for promoting the healthy development of lung function and preventing chronic respiratory diseases in Chinese children. Methods: A cluster stratified sampling method was used to select a total of 893 pupils in grades 2-5 from Chengdu in November 2021. Dietary data of respondents were collected using a food frequency questionnaire within the past year,then the food group intake was categorized into T1, T2 and T3 from low to high by the trichotomous method, and anthropometric measurements including lung capacity were obtained in 2022. Logistic regression models and test for trend were used to analyze the prospective effects of intake of each food group on lung function development of pupils. Results: Among male students, consumption of vegetables [118.6(50.5, 188.2)g/d] and milk and dairy products [200.0(73.3, 250.0)g/d] were higher in the excellent lung capacity group than in the non excellent lung capacity group [90.0(37.1, 192.9), and 178.6(35.7, 250.0)g/d],with statistically significant differences ( Z =-1.98, -2.24); among girls, the group with excellent lung capacity consumed less staple food [391.1(273.6, 511.4)g/d] than the group with non excellent lung capacity [407.4(309.5, 594.3)g/d], and the group with excellent lung capacity consumed more aquatic products [31.2(14.6, 69.8)g/d] and milk and dairy products [215.0(107.1, 250.1) g/d ] than that of the non excellent lung capacity [19.4(10.7, 58.3), 114.3(35.7, 250.0)g/d] ( Z =-2.01, -3.33, -5.10)( P < 0.05 ). After adjusting for energy, body mass index Z score(BMI Z ), mother s education level, averge family income monthly, whether presence of smokers in the living environment, and whether participation in physical activities during the past week, among male students, T3 group of vegetable intake ( OR =0.48, 95% CI = 0.27-0.86), T2 group of bean and soy product intake ( OR = 0.52 , 95% CI =0.27-0.96)，T2 and T3 groups of milk and dairy products intake (T2： OR =0.54, 95% CI =0.31-0.93; T3： OR = 0.52 , 95% CI =0.30-0.90) were negatively associated with non excellent lung capacity ( P <0.05). Among girls, T3 group of aquatic product intake( OR =0.52, 95% CI =0.28-0.97), T2 and T3 groups of milk and dairy product (T2: OR =0.44, 95% CI =0.25- 0.76 ;T3: OR =0.33, 95% CI =0.19-0.59) were negatively associated with nonexcellent lung capacity, whereas the T2 group of red meat intake ( OR =2.51, 95% CI =1.37-4.67) was positively associated with non excellent lung capacity. Non excellent lung capacity was found to be negatively associated with vegetable and milk and dairy product intake in boys by test for trend; in girls, milk and dairy products intake was negatively associated with non excellent lung capacity, whereas red meat intake was positively associated with non excellent lung capacity ( t =-1.13，-0.44；-3.03，1.95, P trend <0.05). Conclusions Milk and dariy products intakes reduce the risk of non excellent lung capacity in pupils, vegetables intakes reduce the risk of non excellent lung capacity in boys, and the intake of red meat increases the risk of non excellent lung capacity in girls. Promoting rational food choices is necessary for children to improve healthy lung development.
