Dietary Habit Is Associated with Depression and Intelligence: An Observational and Genome-Wide Environmental Interaction Analysis in the UK Biobank Cohort

Dietary habits have considerable impact on brain development and mental health. Despite long-standing interest in the association of dietary habits with mental health, few population-based studies of dietary habits have assessed depression and fluid intelligence. Our aim is to investigate the association of dietary habits with depression and fluid intelligence. In total, 814 independent loci were utilized to calculate the individual polygenic risk score (PRS) for 143 dietary habit-related traits. The individual genotype data were obtained from the UK Biobank cohort. Regression analyses were then conducted to evaluate the association of dietary habits with depression and fluid intelligence, respectively. PLINK 2.0 was utilized to detect the single nucleotide polymorphism (SNP) × dietary habit interaction effect on the risks of depression and fluid intelligence. We detected 22 common dietary habit-related traits shared by depression and fluid intelligence, such as red wine glasses per month, and overall alcohol intake. For interaction analysis, we detected that OLFM1 interacted with champagne/white wine in depression, while SYNPO2 interacted with coffee type in fluid intelligence. Our study results provide novel useful information for understanding how eating habits affect the fluid intelligence and depression.

苏州市儿童青少年身高别血压筛查简表的效果评价

目的 基于苏州市7~17岁儿童青少年评价身高别血压筛查简表的效果,为制定儿童青少年血压综合防控策略和措施提供参考。方法 采用分层整群随机抽样方法,2017-2018年抽取苏州市7~17岁学生6 972名,进行问卷调查,测量其身高、体重和血压。依据《7～18岁儿童青少年血压偏高筛查界值(WS/T 610-2018)》为“金标准”,评价根据金标准建立的身高别血压筛查简表筛查正常血压高值和血压偏高的效果。结果 根据金标准和身高别血压筛查简表,苏州7~17岁儿童青少年正常血压高值检出率分别为16.7%和16.6%,血压偏高检出率分别为12.7%和12.8%;配对χ²检验显示两标准评价效果差异无统计学意义(χ²=1.376,P=0.711)。与金标准相比,身高别血压筛查简表筛查正常血压高值,血压偏高具有较好的一致性。筛查正常血压高值的受试者工作特征曲线下面积(95%置信区间)、灵敏度、特异度和Kappa值分别为0.900(0.887~0.913)、83.2%、96.8%和0.803,对应的筛查血压偏高值分别为0.925(0.911~0.938)、86.9%、98.0%和0.848。结论 身高别血压筛查简表使用方便,筛查正常血压高值和血压偏高效果很好。     

Undocumented Migrants Reintroducing COVID-19, Yunnan Province,China

To limit the spread of severe acute respiratory syndrome coronavirus 2, the government of China has been monitoring infected travelers and minimizing cold-chain contamination. However, other factors might contribute to recurring outbreaks. We analyze the role of undocumented migrants as potential transmitters of severe acute respiratory syndrome coronavirus 2 in China.

少数民族地区青少年对新冠疫情的认知调查

目的调查少数民族地区青少年对新冠疫情的认知及应对情况。方法采用分层抽样的方法,通过“问卷星”在线平台对香格里拉市1949名在校学生进行调查。结果结果显示,81.94%的学生在2020年1月初之前已知晓疫情;83.12%的学生通过电视和微信知晓疫情;9333%的学生认为病毒通过飞沫传播;94.80%的学生会通过戴口罩、不聚餐等方式进行防护;疫情相关知识的正确率为71.44%。不同年龄、性别、民族、专业、生源地、家庭年收入的学生对部分调查问题的差异有统计学意义(P<0.05)。结论学生对疫情认知整体情况较好,部分问题仍有较大提升空间。学校应做好疫情常态化防控,完善心理疏导体系,多措并举,引导学生做好自我防护。
