Background: Excess consumption of salt is linked to an increased risk of hypertension and cardiovascular disease. The United Kingdom has had a comprehensive salt reduction programme since 2003, setting a series of progressively lower, product-specific reformulation targets for the food industry, combined with advice to consumers to reduce salt. The aim of this study was to assess the changes in the sales-weighted mean salt content of grocery foods sold through retail between 2015 and 2020 by category and company.

Methods and findings: Information for products, including salt content (g/100 g), was collected online from retailer websites for 6 consecutive years (2015 to 2020) and was matched with brand-level retail sales data from Euromonitor for 395 brands. The sales-weighted mean salt content and total volume of salt sold were calculated by category and company. The mean salt content of included foods fell by 0.05 g/100 g, from 1.04 g/100 g in 2015 to 0.90 g/100 g in 2020, equivalent to -4.2% (p = 0.13). The categories with the highest salt content in 2020 were savoury snacks (1.6 g/100 g) and cheese (1.6 g/100 g), and the categories that saw the greatest reductions in mean salt content over time were breakfast cereals (-16.0%, p = 0.65); processed beans, potatoes, and vegetables (-10.6%, p = 0.11); and meat, seafood, and alternatives (-9.2%, p = 0.56). The total volume of salt sold fell from 2.41 g per person per day to 2.25 g per person per day, a reduction of 0.16 g or 6.7% (p = 0.54). The majority (63%) of this decrease was attributable to changes in mean salt content, with the remaining 37% accounted for by reductions in sales. Across the top 5 companies in each of 9 categories, the volume of salt sold decreased in 26 and increased in 19 cases. This study is limited by its exclusion of foods purchased out of the home, including at restaurants, cafes, and takeaways. It also does not include salt added at the table, or that naturally occurring in foods, meaning the findings underrepresent the population's total salt intake. The assumption was also made that the products matched with the sales data were entirely representative of the brand, which may not be the case if products are sold exclusively in convenience stores or markets, which are not included in this database.

Conclusions: There has been a small decline in the salt content of foods and total volume of salt sold between 2015 and 2020, but observed changes were not statistically significant so could be due to random variations over time. We suggest that mandatory reporting of salt sales by large food companies would increase the transparency of how individual businesses are progressing towards the salt reduction targets.

背景:过量食用盐与高血压和心血管疾病的风险增加有关。自2003年以来,英国已经实施了一项全面的减盐计划,为食品工业制定了一系列逐步降低的、针对特定产品的重新配方目标,并建议消费者减少盐的摄入。本研究的目的是评估2015年至2020年间零售食品中按类别和公司销售的销售加权平均含盐量的变化。方法与发现:我们连续6年(2015年至2020年)在零售商网站上收集产品的信息,包括含盐量(g/100 g),并与欧睿咨询的395个品牌的品牌级零售销售数据进行匹配。按类别和公司计算销售加权平均含盐量和销售总量。纳入食品的平均含盐量下降0.05 g/100 g,从2015年的1.04 g/100 g下降到2020年的0.90 g/100 g,相当于-4.2% (p = 0.13)。2020年含盐量最高的类别是咸味零食(1.6 g/100 g)和奶酪(1.6 g/100 g),随着时间的推移,平均含盐量减少最多的类别是早餐麦片(-16.0%,p = 0.65);加工过的豆类、土豆和蔬菜(-10.6%,p = 0.11);肉类、海鲜和替代品(-9.2%,p = 0.56)。盐的总销售量从每人每天2.41 g下降到每人每天2.25 g,减少了0.16 g或6.7% (p = 0.54)。减少的大部分(63%)是由于平均含盐量的变化,剩下的37%是由于销售额的减少。在9个类别中排名前5位的公司中,26家公司的盐销量下降,19家公司的盐销量增加。这项研究的局限性在于它排除了在家里购买的食物,包括在餐馆、咖啡馆和外卖。它也不包括餐桌上添加的盐,也不包括食物中自然存在的盐,这意味着研究结果不能充分代表人口的总盐摄入量。我们还假设与销售数据相匹配的产品完全代表该品牌,如果产品仅在便利店或市场销售,则可能不是这种情况,这些产品不包括在这个数据库中。结论:2015年至2020年期间,食品含盐量和盐销售总量略有下降,但观察到的变化在统计上并不显著,因此可能是随时间的随机变化。我们建议,大型食品公司强制报告盐的销售情况,将增加个体企业如何实现减盐目标的透明度。

UNAIDS and a broad range of partners have collaborated to establish a new set of HIV prevention targets to be achieved by 2025 as an intermediate step towards the sustainable development target for 2030.The number of new HIV infections in the world continues to decline, in part due to the extraordinary expansion of effective HIV treatment. However, the decline is geographically heterogeneous, with some regions reporting a rise in incidence. The incidence target that was agreed for 2020 has been missed.A range of exciting new HIV prevention technologies have become available or are in the pipeline but will only have an impact if they are accessible and affordable and delivered within systems that take full account of the social and political context in which most infections occur. Most new infections occur in populations that are marginalised or discriminated against due to structural, legal, and cultural barriers.The new targets imply a new approach to HIV prevention that emphasises appropriate, person-centred, prioritised, effective, combination HIV prevention within a framework that reduces existing barriers to services and acknowledges heterogeneity, autonomy, and choice.These targets have consequences for people working in HIV programmes both for delivery and for monitoring and evaluation, for health planners setting local and national priorities, and for funders both domestic and global. Most importantly, they have consequences for people who are at risk of HIV exposure and infection.Achieving these targets will have a huge impact on the future of the HIV epidemic and put us back on track towards ending AIDS as a public health threat by 2030.

艾滋病规划署和广泛的合作伙伴合作制定了一套新的艾滋病毒预防目标,将在2025年之前实现,作为实现2030年可持续发展目标的中间步骤。世界上新感染艾滋病毒的人数继续下降,部分原因是有效的艾滋病毒治疗范围大大扩大。然而,这种下降在地理上是不均匀的,一些地区报告发病率上升。商定的2020年发病率目标未能实现。一系列令人振奋的艾滋病毒预防新技术已经出现或正在酝酿之中,但只有在这些技术易于获得、负担得起并在充分考虑到大多数感染发生的社会和政治背景的系统内提供的情况下,才会产生影响。大多数新发感染发生在由于结构、法律和文化障碍而被边缘化或受歧视的人群中。新的目标意味着一种新的艾滋病毒预防方法,在减少现有服务障碍的框架内强调适当的、以人为本的、优先的、有效的综合艾滋病毒预防,并承认异质性、自主性和选择。这些目标对从事艾滋病毒方案工作的人员、对制定地方和国家优先事项的卫生规划人员以及对国内和全球供资者都有影响。最重要的是,它们会对面临艾滋病毒暴露和感染风险的人产生影响。实现这些目标将对艾滋病毒流行病的未来产生巨大影响,并使我们回到到2030年消除艾滋病这一公共卫生威胁的轨道上。

Background: In sub-Saharan Africa (SSA), adolescent girls and young women (AGYW) ages 15 to 24 years represent <10% of the population yet account for 1 in 5 new HIV infections. Although oral pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) can be highly effective, low persistence in PrEP programs and poor adherence have limited its ability to reduce HIV incidence among women.

Methods and findings: A total of 336 AGYW participating in the PEPFAR-funded DREAMS PrEP program in western Kenya were enrolled into a study of PrEP use conducted between 6/2019 to 1/2020. AGYW, who used daily oral TDF/FTC, completed interviews and provided dried blood spots (DBS) for measurement of tenofovir-diphosphate (TFV-DP) concentrations at enrollment and 3 months later, and 176/302 (58.3%, 95% confidence interval [95% CI 52.3 to 63.8]) met our definition of PrEP persistence: having expressed intention to use PrEP and attended both the second interview and an interim refill visit. Among AGYW with DBS taken at the second interview, only 9/197 (4.6%, [95% CI 1.6 to 7.5]) had protective TFV-DP levels (≥700 fmol/punch) and 163/197 (82.7%, [95% CI 77.5 to 88]) had levels consistent with no recent PrEP use (<10 fmol/punch). Perception of being at moderate-to-high risk for HIV if not taking PrEP was associated with persistence (adjusted odds ratio, 10.17 [95% CI 5.14 to 20.13], p < 0.001) in a model accounting for county of residence and variables that had p-value <0.1 in unadjusted analysis (age, being in school, initiated PrEP 2 to 3 months before the first interview, still active in DREAMS, having children, having multiple sex partners, partner aware of PrEP use, partner very supportive of PrEP use, partner has other partners, AGYW believes that a partner puts her at risk, male condom use, injectable contraceptive use, and implant contraceptive use). Among AGYW who reported continuing PrEP, >90% indicated they were using PrEP to prevent HIV, although almost all had non-protective TFV-DP levels. Limitations included short study duration and inclusion of only DREAMS participants.

Conclusions: Many AGYW persisted in the PrEP program without taking PrEP frequently enough to receive benefit. Notably, AGYW who persisted had a higher self-perceived risk of HIV infection. These AGYW may be optimal candidates for long-acting PrEP.

背景:在撒哈拉以南非洲(SSA),年龄在15至24岁的少女和年轻女性(AGYW)代表了方法和研究结果:参与pepfar资助的肯尼亚西部DREAMS PrEP项目的336名AGYW被纳入了2019年6月至2020年1月期间进行的PrEP使用研究。AGYW每日口服TDF/FTC,完成访谈并提供干血点(DBS)用于在入组时和3个月后测量替诺福韦-二磷酸(ttfv - dp)浓度,其中176/302(58.3%,95%置信区间[95% CI 52.3至63.8])符合我们对PrEP持久性的定义:表示有意使用PrEP,并参加了第二次访谈和临时补充访问。在第二次访谈中接受DBS的AGYW中,只有9/197 (4.6%,[95% CI 1.6至7.5])具有保护性tv - dp水平(≥700 fmol/punch), 163/197 (82.7%, [95% CI 77.5至88])的水平与近期未使用PrEP一致(90%表示他们正在使用PrEP预防艾滋病毒,尽管几乎所有人都具有非保护性tv - dp水平。局限性包括研究持续时间短且仅纳入了DREAMS参与者。结论:许多AGYW坚持PrEP计划,但服用PrEP的频率不足以获得益处。值得注意的是,持续存在的AGYW有更高的自我感知的艾滋病毒感染风险。这些AGYW可能是长效PrEP的最佳候选药物。

<p><strong>Background: </strong>Treatment for gestational diabetes mellitus (GDM) aims to reduce maternal hyperglycaemia. The TARGET Trial assessed whether tighter compared with less tight glycaemic control reduced maternal and perinatal morbidity.</p><p><strong>Methods and findings: </strong>In this stepped-wedge, cluster-randomised trial, identification number ACTRN12615000282583, 10 hospitals in New Zealand were randomised to 1 of 5 implementation dates. The trial was registered before the first participant was enrolled. All hospitals initially used less tight targets (fasting plasma glucose (FPG) <5.5 mmol/L (<99 mg/dL), 1-hour <8.0 mmol/L (<144 mg/dL), 2 hour postprandial <7.0 mmol/L (<126 mg/dL)) and every 4 months, 2 hospitals moved to use tighter targets (FPG ≤5.0 mmol/L (≤90 mg/dL), 1-hour ≤7.4 mmol/L (≤133 mg/dL), 2 hour postprandial ≤6.7 mmol/L) (≤121 mg/dL). Women with GDM, blinded to the targets in use, were eligible. The primary outcome was large for gestational age. Secondary outcomes assessed maternal and infant health. Analyses were by intention to treat. Between May 2015 and November 2017, data were collected from 1,100 women with GDM (1,108 infants); 598 women (602 infants) used the tighter targets and 502 women (506 infants) used the less tight targets. The rate of large for gestational age was similar between the treatment target groups (88/599, 14.7% versus 76/502, 15.1%; adjusted relative risk [adjRR] 0.96, 95% confidence interval [CI] 0.66 to 1.40, P = 0.839). The composite serious health outcome for the infant of perinatal death, birth trauma, or shoulder dystocia was apparently reduced in the tighter group when adjusted for gestational age at diagnosis of GDM, BMI, ethnicity, and history of GDM compared with the less tight group (8/599, 1.3% versus 13/505, 2.6%, adjRR 0.23, 95% CI 0.06 to 0.88, P = 0.032). No differences were seen for the other infant secondary outcomes apart from a shorter stay in intensive care (P = 0.041). Secondary outcomes for the woman showed an apparent increase for the composite serious health outcome that included major haemorrhage, coagulopathy, embolism, and obstetric complications in the tighter group (35/595, 5.9% versus 15/501, 3.0%, adjRR 2.29, 95% CI 1.14 to 4.59, P = 0.020). There were no differences between the target groups in the risk for pre-eclampsia, induction of labour, or cesarean birth, but more women using tighter targets required pharmacological treatment (404/595, 67.9% versus 293/501, 58.5%, adjRR 1.20, 95% CI 1.00 to 1.44, P = 0.047).

The trial was registered before the first participant was enrolled. All hospitals initially used less tight targets (fasting plasma glucose (FPG) &lt;5.5 mmol/L (&lt;99 mg/dL), 1-hour &lt;8.0 mmol/L (&lt;144 mg/dL), 2 hour postprandial &lt;7.0 mmol/L (&lt;126 mg/dL)) and every 4 months, 2 hospitals moved to use tighter targets (FPG ≤5.0 mmol/L (≤90 mg/dL), 1-hour ≤7.4 mmol/L (≤133 mg/dL), 2 hour postprandial ≤6.7 mmol/L) (≤121 mg/dL). Women with GDM, blinded to the targets in use, were eligible. The primary outcome was large for gestational age. Secondary outcomes assessed maternal and infant health. Analyses were by intention to treat. Between May 2015 and November 2017, data were collected from 1,100 women with GDM (1,108 infants); 598 women (602 infants) used the tighter targets and 502 women (506 infants) used the less tight targets. The rate of large for gestational age was similar between the treatment target groups (88/599, 14.7% versus 76/502, 15.1%; adjusted relative risk [adjRR] 0.96, 95% confidence interval [CI] 0.66 to 1.40, P = 0.839).

<p><strong>Background: </strong>The Coronavirus Disease 2019 (COVID-19) pandemic has had wide-reaching direct and indirect impacts on population health. In low- and middle-income countries, these impacts can halt progress toward reducing maternal and child mortality. This study estimates changes in health services utilization during the pandemic and the associated consequences for maternal, neonatal, and child mortality.</p><p><strong>Methods and findings: </strong>Data on service utilization from January 2018 to June 2021 were extracted from health management information systems of 18 low- and lower-middle-income countries (Afghanistan, Bangladesh, Cameroon, Democratic Republic of the Congo (DRC), Ethiopia, Ghana, Guinea, Haiti, Kenya, Liberia, Madagascar, Malawi, Mali, Nigeria, Senegal, Sierra Leone, Somalia, and Uganda). An interrupted time-series design was used to estimate the percent change in the volumes of outpatient consultations and maternal and child health services delivered during the pandemic compared to projected volumes based on prepandemic trends. The Lives Saved Tool mathematical model was used to project the impact of the service utilization disruptions on child and maternal mortality. In addition, the estimated monthly disruptions were also correlated to the monthly number of COVID-19 deaths officially reported, time since the start of the pandemic, and relative severity of mobility restrictions. Across the 18 countries, we estimate an average decline in OPD volume of 13.1% and average declines of 2.6% to 4.6% for maternal and child services. We projected that decreases in essential health service utilization between March 2020 and June 2021 were associated with 113,962 excess deaths (110,686 children under 5, and 3,276 mothers), representing 3.6% and 1.5% increases in child and maternal mortality, respectively. This excess mortality is associated with the decline in utilization of the essential health services included in the analysis, but the utilization shortfalls vary substantially between countries, health services, and over time. The largest disruptions, associated with 27.5% of the excess deaths, occurred during the second quarter of 2020, regardless of whether countries reported the highest rate of COVID-19-related mortality during the same months. There is a significant relationship between the magnitude of service disruptions and the stringency of mobility restrictions. The study is limited by the extent to which administrative data, which varies in quality across countries, can accurately capture the changes in service coverage in the population.</p><p><strong>Conclusions: </strong>Declines in healthcare utilization during the COVID-19 pandemic amplified the pandemic's harmful impacts on health outcomes and threaten to reverse gains in reducing maternal and child mortality.

背景:2019 年冠状病毒病(COVID-19)大流行对人口健康产生了广泛的直接和间接影响。在中低收入国家,这些影响可能会阻碍降低孕产妇和儿童死亡率的进程。本研究估算了大流行期间医疗服务利用率的变化以及对孕产妇、新生儿和儿童死亡率的相关影响:从 18 个低收入和中低收入国家(阿富汗、孟加拉国、喀麦隆、刚果民主共和国、埃塞俄比亚、加纳、几内亚、海地、肯尼亚、利比里亚、马达加斯加、马拉维、马里、尼日利亚、塞内加尔、塞拉利昂、索马里和乌干达)的卫生管理信息系统中提取了 2018 年 1 月至 2021 年 6 月的服务利用率数据。采用间断时间序列设计来估算大流行期间提供的门诊咨询和妇幼保健服务量与根据大流行前趋势预测的服务量相比的百分比变化。拯救生命工具 "数学模型用于预测服务利用中断对儿童和孕产妇死亡率的影响。此外,估计的每月中断情况还与每月正式报告的 COVID-19 死亡人数、大流行开始以来的时间以及流动限制的相对严重程度相关。在 18 个国家中,我们估计门诊量平均下降 13.1%,孕产妇和儿童服务平均下降 2.6% 至 4.6%。我们预测,2020 年 3 月至 2021 年 6 月期间基本医疗服务利用率的下降将导致 113,962 例超额死亡(110,686 例 5 岁以下儿童死亡和 3,276 例母亲死亡),这意味着儿童和孕产妇死亡率分别增加了 3.6% 和 1.5%。超额死亡率与分析中包括的基本医疗服务利用率下降有关,但利用率不足的情况因国家、医疗服务和时间的不同而有很大差异。最大的中断发生在 2020 年第二季度,占超额死亡人数的 27.5%,与各国是否在同一月份报告了最高的 COVID-19 相关死亡率无关。服务中断的程度与流动限制的严格程度之间存在重要关系。由于各国的行政数据质量不一,这项研究受到了行政数据能否准确反映人口中服务覆盖率变化的限制:结论:在 COVID-19 大流行期间,医疗保健利用率的下降扩大了大流行对健康结果的有害影响,并有可能逆转在降低孕产妇和儿童死亡率方面取得的成果。随着预防和治疗 COVID-19 的努力和资源分配的继续,必须维持基本的医疗服务,尤其是在低收入和中等收入国家。

Background Despite availability of clinical practice guidelines for hypertension management, blood pressure (BP) control remains sub-optimal (<30%) even in high-income countries. This study aims to assess the effectiveness of a potentially scalable multicomponent intervention integrated into primary care system compared to usual care on BP control. Methods and findings A cluster-randomized controlled trial was conducted in 8 government clinics in Singapore. The trial enrolled 916 patients aged ≥40 years with uncontrolled hypertension (systolic BP (SBP) ≥140 mmHg or diastolic BP (DBP) ≥90 mmHg). Multicomponent intervention consisted of physician training in risk-based treatment of hypertension, subsidized losartan-HCTZ single-pill combination (SPC) medications, nurse training in motivational conversations (MCs), and telephone follow-ups. Usual care (controls) comprised of routine care in the clinics, no MC or telephone follow-ups, and no subsidy on SPCs. The primary outcome was mean SBP at 24 months’ post-baseline. Four clinics (447 patients) were randomized to intervention and 4 (469) to usual care. Patient enrolment commenced in January 2017, and follow-up was during December 2018 to September 2020. Analysis used intention-to-treat principles. The primary outcome was SBP at 24 months. BP at baseline, 12 and 24 months was modeled at the patient level in a likelihood-based, linear mixed model repeated measures analysis with treatment group, follow-up, treatment group × follow-up interaction as fixed effects, and random cluster (clinic) effects. A total of 766 (83.6%) patients completed 2-year follow-up. A total of 63 (14.1%) and 87 (18.6%) patients in intervention and in usual care, respectively, were lost to follow-up. At 24 months, the adjusted mean SBP was significantly lower in the intervention group compared to usual care (−3.3 mmHg; 95% CI: −6.34, −0.32; p = 0.03). The intervention led to higher BP control (odds ratio 1.51; 95% CI: 1.10, 2.09; p = 0.01), lower odds of high (>20%) 10-year cardiovascular risk score (OR 0.67; 95% CI: 0.47, 0.97; p = 0.03), and lower mean log albuminuria (−0.22; 95% CI: −0.41, −0.02; p = 0.03). Mean DBP, mortality rates, and serious adverse events including hospitalizations were not different between groups. The main limitation was no masking in the trial. Conclusions A multicomponent intervention consisting of physicians trained in risk-based treatment, subsidized SPC medications, nurse-delivered motivational conversation, and telephone follow-ups improved BP control and lowered cardiovascular risk. Wide-scale implementation of a multicomponent intervention such as the one in our trial is likely to reduce hypertension-related morbidity and mortality globally. Trial registration Trial Registration: Clinicaltrials.gov NCT02972619.
背景:尽管有高血压管理的临床实践指南,但血压(BP)控制仍然不理想(20%),10年心血管风险评分(OR 0.67;95% ci: 0.47, 0.97;P = 0.03),较低的平均对数蛋白尿(- 0.22;95% ci:−0.41,−0.02;P = 0.03)。平均舒张压、死亡率和包括住院在内的严重不良事件在两组之间没有差异。主要的限制是在试验中没有掩蔽。结论:由接受过基于风险的治疗培训的医生、补贴的SPC药物、护士提供的激励谈话和电话随访组成的多组分干预可以改善血压控制并降低心血管风险。在我们的试验中,大规模实施多组分干预可能会降低全球高血压相关的发病率和死亡率。试验注册:Clinicaltrials.gov NCT02972619。

Background Road traffic noise is a prevalent and known health hazard. However, little is known yet about its effect on children’s cognition. We aimed to study the association between exposure to road traffic noise and the development of working memory and attention in primary school children, considering school-outdoor and school-indoor annual average noise levels and noise fluctuation characteristics, as well as home-outdoor noise exposure. Methods and findings We followed up a population-based sample of 2,680 children aged 7 to 10 years from 38 schools in Barcelona (Catalonia, Spain) between January 2012 to March 2013. Children underwent computerised cognitive tests 4 times (n = 10,112), for working memory (2-back task, detectability), complex working memory (3-back task, detectability), and inattentiveness (Attention Network Task, hit reaction time standard error, in milliseconds). Road traffic noise was measured indoors and outdoors at schools, at the start of the school year, using standard protocols to obtain A-weighted equivalent sound pressure levels, i.e., annual average levels scaled to human hearing, for the daytime (daytime LAeq, in dB). We also derived fluctuation indicators out of the measurements (noise intermittency ratio, %; and number of noise events) and obtained individual estimated indoor noise levels (LAeq) correcting for classroom orientation and classroom change between years. Home-outdoor noise exposure at home (Lden, i.e., EU indicator for the 24-hour annual average levels) was estimated using Barcelona’s noise map for year 2012, according to the European Noise Directive (2002). We used linear mixed models to evaluate the association between exposure to noise and cognitive development adjusting for age, sex, maternal education, socioeconomical vulnerability index at home, indoor or outdoor traffic-related air pollution (TRAP) for corresponding school models or outdoor nitrogen dioxide (NO2) for home models. Child and school were included as nested random effects. The median age (percentile 25, percentile 75) of children in visit 1 was 8.5 (7.8; 9.3) years, 49.9% were girls, and 50% of the schools were public. School-outdoor exposure to road traffic noise was associated with a slower development in working memory (2-back and 3-back) and greater inattentiveness over 1 year in children, both for the average noise level (e.g., ‒4.83 points [95% CI: ‒7.21, ‒2.45], p-value < 0.001, in 2-back detectability per 5 dB in street levels) and noise fluctuation (e.g., ‒4.38 [‒7.08, ‒1.67], p-value = 0.002, per 50 noise events at street level).

背景道路交通噪声是一种普遍且已知的健康危害。然而,人们对其对儿童认知的影响知之甚少。我们旨在研究小学儿童暴露于道路交通噪声与工作记忆和注意力发展之间的关系,考虑学校室外和学校室内的年平均噪声水平和噪声波动特征,以及家庭室外噪声暴露。方法和发现我们在2012年1月至2013年3月期间对巴塞罗那(西班牙加泰罗尼亚)38所学校的2680名7至10岁儿童进行了基于人群的随访。儿童接受了4次计算机认知测试(n=10112),包括工作记忆(2背任务,可检测性)、复杂工作记忆(3背任务,检测性)和注意力不集中(注意力网络任务,命中反应时间标准误差,以毫秒为单位)。在学年开始时,使用标准协议对学校的室内和室外道路交通噪声进行了测量,以获得A加权等效声压水平,即按人类听力换算的日间平均水平(日间LAeq,单位为dB)。我们还从测量中得出了波动指标(噪声间歇率,%;和噪声事件的数量),并获得了个人估计的室内噪声水平(LAeq),校正了教室方向和教室在不同年份之间的变化。根据《欧洲噪音指令》(2002年),使用巴塞罗那2012年的噪音地图估计了家中的家庭户外噪音暴露量(Lden,即欧盟24小时年平均水平指标)。我们使用线性混合模型来评估暴露于噪音与认知发展之间的关系,并根据年龄、性别、母亲教育、家庭社会经济脆弱性指数、相应学校模型的室内或室外交通相关空气污染(TRAP)或家庭模型的室外二氧化氮(NO2)进行调整。儿童和学校被纳入嵌套随机效应。访视1中儿童的中位年龄(百分位数25,百分位数75)为8.5(7.8;9.3)岁,49.9%为女孩,50%的学校为公立学校。学校户外暴露于道路交通噪音与儿童工作记忆(2背和3背)发展较慢和1年以上注意力不集中有关,平均噪声水平(例如,-4.83点[95%CI:-7.21,-2.45],p值<0.001,在街道水平每5 dB的2个背景可检测性中)和噪声波动(例如,街道水平每50个噪声事件-4.38[-7.08,-1.67],p=0.002)。个人在教室中暴露于道路交通平均噪音水平仅与注意力不集中有关(2.49ms[04.81],p值=0.050,每5dB),而室内噪音波动始终与所有结果有关。家庭户外噪声暴露与结果无关。研究的局限性包括潜在的缺乏可推广性(在我们的研究中,58%的母亲拥有大学学历,而该地区只有50%)以及缺乏过去的噪音暴露评估。结论我们观察到,在学校而不是在家暴露于道路交通噪音与1年以上学童的工作记忆、复杂工作记忆和注意力发展较慢有关。与教室中的平均噪音水平相比,与噪音波动指标的关联更为明显。

However, little is known yet about its effect on children’s cognition. We aimed to study the association between exposure to road traffic noise and the development of working memory and attention in primary school children, considering school-outdoor and school-indoor annual average noise levels and noise fluctuation characteristics, as well as home-outdoor noise exposure. Methods and findings We followed up a population-based sample of 2,680 children aged 7 to 10 years from 38 schools in Barcelona (Catalonia, Spain) between January 2012 to March 2013. Children underwent computerised cognitive tests 4 times (n = 10,112), for working memory (2-back task, detectability), complex working memory (3-back task, detectability), and inattentiveness (Attention Network Task, hit reaction time standard error, in milliseconds). Road traffic noise was measured indoors and outdoors at schools, at the start of the school year, using standard protocols to obtain A-weighted equivalent sound pressure levels, i.e., annual average levels scaled to human hearing, for the daytime (daytime LAeq, in dB). We also derived fluctuation indicators out of the measurements (noise intermittency ratio, %; and number of noise events) and obtained individual estimated indoor noise levels (LAeq) correcting for classroom orientation and classroom change between years. Home-outdoor noise exposure at home (Lden, i.e., EU indicator for the 24-hour annual average levels) was estimated using Barcelona’s noise map for year 2012, according to the European Noise Directive (2002). We used linear mixed models to evaluate the association between exposure to noise and cognitive development adjusting for age, sex, maternal education, socioeconomical vulnerability index at home, indoor or outdoor traffic-related air pollution (TRAP) for corresponding school models or outdoor nitrogen dioxide (NO2) for home models. Child and school were included as nested random effects. The median age (percentile 25, percentile 75) of children in visit 1 was 8.5 (7.8; 9.3) years, 49.9% were girls, and 50% of the schools were public. School-outdoor exposure to road traffic noise was associated with a slower development in working memory (2-back and 3-back) and greater inattentiveness over 1 year in children, both for the average noise level (e.g., ‒4.83 points [95% CI: ‒7.21, ‒2.45], p-value &lt; 0.001, in 2-back detectability per 5 dB in street levels) and noise fluctuation (e.g., ‒4.38 [‒7.08, ‒1.67], p-value = 0.002, per 50 noise events at street level). Individual exposure to the road traffic average noise level in classrooms was only associated with inattentiveness (2.49 ms [0, 4.81], p-value = 0.050, per 5 dB), whereas indoor noise fluctuation was consistently associated with all outcomes.

Background The provision of different types of mortality metrics (e.g., mortality rate ratios [MRRs] and life expectancy) allows the research community to access a more informative set of health metrics. The aim of this study was to provide a panel of mortality metrics associated with a comprehensive range of disorders and to design a web page to visualize all results. Methods and findings In a population-based cohort of all 7,378,598 persons living in Denmark at some point between 2000 and 2018, we identified individuals diagnosed at hospitals with 1,803 specific categories of disorders through the International Classification of Diseases-10th Revision (ICD-10) in the National Patient Register. Information on date and cause of death was obtained from the Registry of Causes of Death. For each of the disorders, a panel of epidemiological and mortality metrics was estimated, including incidence rates, age-of-onset distributions, MRRs, and differences in life expectancy (estimated as life years lost [LYLs]). Additionally, we examined models that adjusted for measures of air pollution to explore potential associations with MRRs. We focus on 39 general medical conditions to simplify the presentation of results, which cover 10 broad categories: circulatory, endocrine, pulmonary, gastrointestinal, urogenital, musculoskeletal, hematologic, mental, and neurologic conditions and cancer. A total of 3,676,694 males and 3,701,904 females were followed up for 101.7 million person-years. During the 19-year follow-up period, 1,034,273 persons (14.0%) died. For 37 of the 39 selected medical conditions, mortality rates were larger and life expectancy shorter compared to the Danish general population. For these 37 disorders, MRRs ranged from 1.09 (95% confidence interval [CI]: 1.09 to 1.10) for vision problems to 7.85 (7.77 to 7.93) for chronic liver disease, while LYLs ranged from 0.31 (0.14 to 0.47) years (approximately 16 weeks) for allergy to 17.05 (16.95 to 17.15) years for chronic liver disease. Adjustment for air pollution had very little impact on the estimates; however, a limitation of the study is the possibility that the association between the different disorders and mortality could be explained by other underlying factors associated with both the disorder and mortality. Conclusions In this study, we show estimates of incidence, age of onset, age of death, and mortality metrics (both MRRs and LYLs) for a comprehensive range of disorders. The interactive data visualization site (https://nbepi.com/atlas) allows more fine-grained analysis of the link between a range of disorders and key mortality estimates.
背景提供不同类型的死亡率指标(例如,死亡率[MRR]和预期寿命)使研究界能够获得一套信息更丰富的健康指标。这项研究的目的是提供一组与一系列疾病相关的死亡率指标,并设计一个网页来可视化所有结果。方法和发现在2000年至2018年间的某个时间点,我们对居住在丹麦的所有7378598人进行了基于人群的队列研究,通过国家患者登记册中的国际疾病分类第10次修订版(ICD-10),我们确定了在医院诊断出患有1803种特定疾病的人。关于死亡日期和原因的信息是从死亡原因登记处获得的。对于每种疾病,都估计了一组流行病学和死亡率指标,包括发病率、发病年龄分布、MRR和预期寿命差异(估计为寿命损失[LYLs])。此外,我们还研究了根据空气污染指标进行调整的模型,以探索与MRR的潜在关联。我们将重点放在39种常见疾病上,以简化结果的呈现,这些疾病涵盖10大类:循环系统、内分泌系统、肺部、胃肠道、泌尿生殖系统、肌肉骨骼系统、血液系统、精神和神经系统疾病以及癌症。共对3676694名男性和3701904名女性进行了1.017亿人年的随访。在19年的随访期间,1034273人(14.0%)死亡。在39种选定的疾病中,有37种的死亡率高于丹麦普通人群,预期寿命较短。对于这37种疾病,视力问题的MRRs范围为1.09(95%置信区间[CI]:1.09至1.10),慢性肝病的为7.85(7.77至7.93),而过敏的LYLs范围为0.31(0.14至0.47)年(约16周),慢性肝脏疾病的为17.05(16.95至17.15)年。空气污染的调整对估计数几乎没有影响;然而,该研究的一个局限性是,不同疾病与死亡率之间的联系可能由与疾病和死亡率相关的其他潜在因素来解释。结论在这项研究中,我们对一系列疾病的发病率、发病年龄、死亡年龄和死亡率指标(MRRs和LYL)进行了估计。交互式数据可视化站点(https://nbepi.com/atlas)允许对一系列疾病和关键死亡率估计之间的联系进行更精细的分析。
