Both plastics age relatively quickly, and the degree of damage to the pipe surface depends on the time and operating conditions.

The exposure of nursing infants to POPs has been a significant focus, prompting extensive research into the presence of these substances in human breast milk.

In this study, we expand on previous work to evaluate associations between nighttime aircraft noise exposure and self-reported hypertension incidence in the Nurses' Health Studies (NHS/NHSII), two US-wide cohorts of female nurses. Annual nighttime average aircraft sound levels (L<sub>night</sub>) surrounding 90 airports for 1995–2015 (in 5-year intervals) were modeled using the Aviation Environmental Design Tool and assigned to participants’ geocoded addresses over time. Hypertension risk was estimated for each cohort using time-varying Cox proportional-hazards models for L<sub>night</sub> dichotomized at 45 dB (dB), adjusting for individual-level hypertension risk factors, area-level socioeconomic status, region, and air pollution. Random effects meta-analysis was used to combine cohort results. Among 63,229 NHS and 98,880 NHSII participants free of hypertension at study baseline (1994/1995), we observed 33,190 and 28,255 new hypertension cases by 2014/2013, respectively. Although ∼1% of participants were exposed to L<sub>night</sub> ≥45 dB, we observed an adjusted hazard ratio (HR) of 1.10 (95% CI: 0.96, 1.27) in NHS and adjusted HR of 1.12 (95% CI: 0.98, 1.28) in NHSII, comparing exposure to L<sub>night</sub> ≥45 versus &lt;45 dB(A). In meta-analysis, we observed an adjusted HR of 1.11 (95% CI: 1.01, 1.23). These results were attenuated with adjustment for additional variables such as body mass index. Our findings support a modest positive association between nighttime aircraft noise and hypertension risk across NHS/NHSII, which may reinforce the concept that sleep disturbance contributes to noise-related disease burden.</p></div>","PeriodicalId":13994,"journal":{"name":"International journal of hygiene and environmental health","volume":"263 ","pages":"Article 114457"},"PeriodicalIF":4.5,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142168292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In November 2020, a war broke out in Tigray, Ethiopia, resulting in a negative health consequence. The post war status of WASH and its associated diseases are not documented. The aim of this study was to assess the status of drinking water, sanitation and hygiene practices and the prevalence of WASH-associated diseases in Tigray, Ethiopia following the war. A community-based cross-sectional study was conducted in 24 randomly selected accessible districts of Tigray, Ethiopia. A standardized questionnaire was used to collect data from households in the study. Data was collected from 2338 households. Descriptive statistics and binary logistic regression were used to analyze the data. The average age of respondents was 28.7 years (SD = 6.2). The majority of respondents 2030 (86.8%) were married and 1698 (72.6%) were rural residents. Nearly one third of the respondents were uneducated and around 40% have either radio or TV as means of communication. More than half (55.2%) of the respondents had a family size of over 5.</p><p>A quarter (25%, 95% CI: 23.3, 26.8) of study participants had access to a basic water supply. Less than a tenth (7.7%, 95% CI: 6.6, 8.8) of households had access to basic sanitation. Basic hand washing was available in 2% of households. Malaria, diarrhoea, skin infection and eye infection were the common reported disease in the community. Marital status, family size, place of residence and liquid waste management were the most important predictors of reported diseases.</p><p>Access to basic water, sanitation and hygiene services was low, and the prevalence of malaria, diarrhoea and skin infections was higher. There were differences in WASH services and reported diseases according to zone and place of residence (urban-rural). Post war, improved access to basic water, sanitation and hygiene services is recommended to prevent WASH-associated diseases in Tigray, Ethiopia. Furthermore, the prevention oriented policy of the country needs better implementation to reduce preventable diseases and ensure better health status in the community.</p></div>","PeriodicalId":13994,"journal":{"name":"International journal of hygiene and environmental health","volume":"263 ","pages":"Article 114460"},"PeriodicalIF":4.5,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142168291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
