Background Unlike influenza, information on the burden of human metapneumovirus (HMPV) as a cause of hospitalizations in adults with acute respiratory illness (ARI) is limited. Methods We compared the population-based incidence, seasonality, and clinical characteristics of these 2 viral infections among adults aged ≥20 years with ARI hospitalizations in Auckland, New Zealand, during 2012–2015 through the Southern Hemisphere Influenza Vaccine Effectiveness Research and Surveillance (SHIVERS) project. Results Of the 14 139 ARI hospitalizations, 276 of 6484 (4.3%) tested positive for HMPV and 1342 of 7027 (19.1%) tested positive for influenza. Crude rates of 9.8 (95% confidence interval [CI], 8.7–11.0) HMPV-associated and 47.6 (95% CI, 45.1–50.1) influenza-associated ARI hospitalizations were estimated for every 100 000 adult residents annually. The highest rates for both viruses were in those aged ≥80 years, of Māori or Pacific ethnicity, or living in low socioeconomic status (SES) areas. HMPV infections were more common than influenza in those with chronic medical conditions. Conclusions Although HMPV infections accounted for fewer hospitalizations than influenza in adults aged ≥20 years, HMPV-associated ARI hospitalization rates were higher than influenza in older adults, Māori and Pacific people, and those of low SES. This highlights a need for vaccine/antiviral development. [ABSTRACT FROM AUTHOR]

Objectives: There are some studies without consensus on the association between metabolic syndrome (MetS) and health-related quality of life (HRQoL) and few studies among elderly participants; therefore, the aim of this study is evaluating the association between MetS and HRQoL between elderly participants after adjusting for possible confounding factors. Methods: A cross-sectional analysis was conducted with the data from baseline phase of the IRanian Longitudinal Study on Ageing. The MetS diagnosis was conducted based on the National Cholesterol Education Program Adult Treatment Panel III guidelines. The participants were 3452 subjects aged ≥60 years with and without MetS. The Prospective Epidemiological Research Studies in Iran version of the SF-12 questionnaire was used to examine subjects' perspectives on their well-being and general health level. The association between MetS and HRQoL was evaluated through multivariable linear regression model after adjusting for possible covariates. Results: MetS independently had an inverse association with subscales of HRQoL including physical functioning, physical problems, general health, social functioning, and emotional problems, even after fully adjusting for studied confounding factors. An inverse association was also observed between MetS and both mental component summary and physical component summary in the fully adjusted model. Conclusion: Older adults with MetS had a relatively worse physical and mental HRQoL in comparison with individuals without MetS. Independent of any underlying factors, the inverse association of MetS with HRQoL emphasizes the necessity of routine screening and treatment of MetS in older populations. [ABSTRACT FROM AUTHOR]

Background: Changes in the epidemiology of illnesses caused by respiratory syncytial virus (RSV) infection following the COVID‐19 pandemic are reported. The New Zealand (NZ) COVID‐19 situation was unique; RSV community transmission was eliminated with the 2020 border closure, with a rapid and large increase in hospitalizations following the relaxation of social isolation measures and the opening of an exclusive border with Australia. Methods: This active population‐based surveillance compared the age‐specific incidence and seasonality of RSV‐associated hospitalizations in Auckland, NZ, for 2 years before and after the 2020 border closures. Hospitalisation rates between years were compared by age, ethnicity (European/other, Māori, Pacific and Asian) and socioeconomic group (1 = least, 5 = most deprived). Results: There was no RSV transmission in 2020. In all other years, hospitalisation rates were highest for people of Pacific versus other ethnic groups and for people living in the most deprived quintile of households. RSV hospitalisation rates were higher in 2021 and 2022 than in 2018–19. The epidemic peak was higher in 2021, but not 2022, and the duration was shorter than in 2018–19. In 2021, the increase in RSV hospitalisation rates was significant across all age, sex, ethnic and socioeconomic groups. In 2022, the increase in hospitalisation rates was only significant in one age (1– < 3 years), one ethnic (Asian) and one socioeconomic group (quintile 2). Conclusions: COVID pandemic responses altered RSV‐related hospitalisation seasonal patterns. Atypical features of RSV hospitalisation epidemiology were the increase in rates in older children and young adults, which lessened in 2022. Despite these variations, RSV hospitalisations in NZ continue to disproportionately affect individuals of Pacific ethnicity and those living in more socioeconomically deprived households. Whilst future public health strategies focused on RSV disease mitigation need to consider the potential shifts in epidemiological patterns when the transmission is disrupted, these variances must be considered in the context of longer‐standing patterns of unequal disease distribution.

Objectives: This study aimed to investigate the relationship between Vitamin D levels and Cardiovascular Diseases (CVDs) such as myocardial infarction (MI), stroke, and angina. Methods: Data for this cross-sectional study were collected as part of the Neyshabur Longitudinal Study on Ageing (NeLSA) between 2016 and 2018. The effect of Vitamin D on CVDs was analyzed in conjunction with socioeconomic and medical history variables. Statistical analysis was conducted using the Chi-square test and logistic regression in the R. Results: Vitamin D levels were evaluated in 3414 participants (1527 men and 1889 women), with over two-thirds of participants showing insufficiency or deficiency of Vitamin D. Among them, 362 participants had self-reported diagnosed CADs. The study did not find a significant association between serum 25OH Vitamin D levels and the risk of CADs. Adjusted logistic regression revealed that male gender was a risk factor for MI (OR=4.7; 95% CI: 3.125-6), stroke (OR=1.75; 95% CI: 1.08-2.85), and angina (OR=1.6; 95% CI: 1.03-2.7). Additionally, having one or more medical conditions other than hypertension and diabetes was associated with angina (OR=7.14; 95% CI: 3.7-14.7), MI (OR=5; 95% CI: 2.97-8.3), and stroke (OR=2.7; 95% CI: 1.2-4.7). Participants aged over 70 years were more likely to experience angina (OR=2.43; 95% CI: 1.36-4.5) and stroke (OR=2.5; 95% CI: 1.35-4.5). Conclusions: The study revealed a high prevalence of Vitamin D deficiency and insufficiency. While the protective role of Vitamin D against CADs was not supported in this study, it does not discount the potential benefits of Vitamin D supplementation for overall health in older individuals.

Background: New Zealand's (NZ) complete absence of community transmission of influenza and respiratory syncytial virus (RSV) after May 2020, likely due to COVID‐19 elimination measures, provided a rare opportunity to assess the impact of border restrictions on common respiratory viral infections over the ensuing 2 years. Methods: We collected the data from multiple surveillance systems, including hospital‐based severe acute respiratory infection surveillance, SHIVERS‐II, ‐III and ‐IV community cohorts for acute respiratory infection (ARI) surveillance, HealthStat sentinel general practice (GP) based influenza‐like illness surveillance and SHIVERS‐V sentinel GP‐based ARI surveillance, SHIVERS‐V traveller ARI surveillance and laboratory‐based surveillance. We described the data on influenza, RSV and other respiratory viral infections in NZ before, during and after various stages of the COVID related border restrictions. Results: We observed that border closure to most people, and mandatory government‐managed isolation and quarantine on arrival for those allowed to enter, appeared to be effective in keeping influenza and RSV infections out of the NZ community. Border restrictions did not affect community transmission of other respiratory viruses such as rhinovirus and parainfluenza virus type‐1. Partial border relaxations through quarantine‐free travel with Australia and other countries were quickly followed by importation of RSV in 2021 and influenza in 2022. Conclusion: Our findings inform future pandemic preparedness and strategies to model and manage the impact of influenza and other respiratory viral threats. [ABSTRACT FROM AUTHOR]

Background: The quality of sleep has different physicalandpsychological consequences, andcan affect students' academic achievement. Objectives: This study aimed to explore factors associated with sleep quality in university students using panel regression. Methods: This study was conducted based on the data from a longitudinal study, namely the "Health and Lifestyle of University Students". The Pittsburgh Sleep Quality Index (PSQI), a self-administered questionnaire containing general information about sleep quality, Beck Anxiety Inventory (BAI), a questionnaire consisting of information about anxiety, Healthy Lifestyle Scale for University Students (HLSUS), and a questionnaire including information about lifestyle were completed by students during the first eight weeks of their first semester. The Panel linear regression and frontier model were used to assess the association of sleep quality with sex, unit, residency, marital status, teeth brushing, drug use, alcoholic drinks, age, anxiety, and healthy lifestyle. Results: A total of 706 individuals (46.8%) suffered from poor sleep quality. Between the two models of panel linear regression and frontier, the former (i.e., panel linear regression) was determined to be a more powerful model with the Akaike information criteria = 3790.68 and Bayesian information criteria = 3899.712, suggesting that the dormitory students with a high level of anxiety and low level of healthy lifestyle had significantly poor sleep quality. Conclusions: Residency, drug use, anxiety, and healthy lifestyle scale were found to be closely associated with sleep quality of university students by using panel linear regression model. Our finding may have been of valuable help to policymakers and planners in their effort to improve the sleep quality of university students. [ABSTRACT FROM AUTHOR]
