Changes in emotional health symptoms in adolescents with specific language impairment

Background: Adolescents and young adults with specific language impairment (SLI) are at risk of experiencing emotional health symptoms, in particular depression and anxiety disorder. However, there is a dearth of research examining issues of stability versus change in symptomatology across time. Aims: To examine depressive and anxiety symptoms reported by adolescents with and without a history of SLI at 16 years, and a year later. Methods & Procedures: Depressive and anxiety symptoms were examined in 90 adolescents with SLI and in 91 adolescents with typical development (TD) initially at 16 years and again at 17 years. Outcomes & Results: Participants with SLI experienced significantly more depressive and anxiety symptoms than participants with TD at 16 years, and continued to experience significantly more anxiety symptoms at 17 years. Females, regardless of language status (SLI versus TD), were more vulnerable than males. The group with SLI evidenced a significant drop in depressive symptoms over the year. A similar change in anxiety symptoms was not apparent. Regression analyses revealed that for individuals with SLI peer problems at 16 years predicted concurrent depressive symptoms, but behavioural factors did not contribute significantly to depressive symptoms at 17 years. For individuals with typical development, hyperactivity at 16 years predicted depressive symptoms at both 16 and 17 years. Language ability and non-verbal IQ did not predict depressive symptoms. Adolescents who experienced more bullying at 16 years were more likely to become, or remain, at risk for depression at 17 years. Conclusions & Implications: Anxiety symptoms appear to be a consistent feature of some individuals with SLI in young adulthood whilst depressive symptoms can diminish

Application of geographic information systems and simulation modelling to dental public health: Where next?

Public health research in dentistry has used geographic information systems since the 1960s. Since then, the methods used in the field have matured, moving beyond simple spatial associations to the use of complex spatial statistics and, on occasions, simulation modelling. Many analyses are often descriptive in nature; however, and the use of more advanced spatial simulation methods within dental public health remains rare, despite the potential they offer the field. This review introduces a new approach to geographical analysis of oral health outcomes in neighbourhoods and small area geographies through two novel simulation methods-spatial microsimulation and agent-based modelling. Spatial microsimulation is a population synthesis technique, used to combine survey data with Census population totals to create representative individual-level population datasets, allowing for the use of individual-level data previously unavailable at small spatial scales. Agent-based models are computer simulations capable of capturing interactions and feedback mechanisms, both of which are key to understanding health outcomes. Due to these dynamic and interactive processes, the method has an advantage over traditional statistical techniques such as regression analysis, which often isolate elements from each other when testing for statistical significance. This article discusses the current state of spatial analysis within the dental public health field, before reviewing each of the methods, their applications, as well as their advantages and limitations. Directions and topics for future research are also discussed, before addressing the potential to combine the two methods in order to further utilize their advantages. Overall, this review highlights the promise these methods offer, not just for making methodological advances, but also for adding to our ability to test and better understand theoretical concepts and pathways

Children's Dental Health Survey, 2003

Abstract copyright UK Data Service and data collection copyright owner.The Children’s Dental Health (CDH) Survey series is a set of national surveys of children’s dental health that have been carried out every 10 years since 1973. Since its inception, the survey has provided important information to underpin the development and monitoring of dental health care for children. The 1973 survey established baseline information on the state of the dental health of children in England and Wales. The survey coverage was then extended in 1983 to include Scotland and Northern Ireland. The 2013 survey covers England, Wales and Northern Ireland. (The UK Data Archive currently does not hold the 1973, 1983 and 1993 surveys). The Children’s Dental Health Survey, 2003 is the fourth survey in the series. The purpose of the survey series is to establish the state of the dental health of children in the UK, and to monitor change since earlier surveys. Further information is available from the Department of Health survey webpage. Main Topics:The data file includes the results of a dental examination carried out with a representative sample of children aged 5, 8, 12 and 15 years of age attending government maintained and independent schools in the UK. The data file also includes the response to a questionnaire completed by a random sub-sample of parents about children's oral hygiene and dental care. Standard measures: A simplified version of the Dental Health Component of the Index of Orthodontic Treatment Need is included. The simplified version only records definite treatment needs and incorporates borderline need into no need categories

Annual Population Survey, July 2018 - June 2019

Abstract copyright UK Data Service and data collection copyright owner.The&nbsp;Annual Population Survey&nbsp;(APS) is a major survey series, which aims to provide data that can produce reliable estimates at the local authority level. Key topics covered in the survey include education, employment, health and ethnicity. The APS comprises key variables from the&nbsp;Labour Force Survey&nbsp;(LFS), all its associated LFS boosts and the APS boost. The APS aims to provide enhanced annual data for England, covering a target sample of at least 510 economically active persons for each Unitary Authority (UA)/Local Authority District (LAD) and at least 450 in each Greater London Borough. In combination with local LFS boost samples, the survey provides estimates for a range of indicators down to Local Education Authority (LEA) level across the United Kingdom.For further detailed information about methodology, users should consult the&nbsp;Labour Force Survey User Guide, included with the APS documentation.

Opinions and Lifestyle Survey, Drinking Module, January - February, April - May, July - August and October - November, 2017

Abstract copyright UK Data Service and data collection copyright owner.The Opinions and Lifestyle Survey (OPN) is an omnibus survey that collects data from respondents in Great Britain. Information is gathered on a range of subjects, commissioned both internally by the Office for National Statistics (ONS) and by external clients (other government departments, charities, non-profit organisations and academia).One individual respondent, aged 16 or over, is selected from each sampled private household to answer questions. Data are gathered on the respondent, their family, address, household, income and education, plus responses and opinions on a variety of subjects within commissioned modules. Each regular OPN survey consists of two elements. Core questions, covering demographic information, are asked together with non-core questions that vary depending on the module(s) fielded.The OPN collects timely data for research and policy analysis evaluation on the social impacts of recent topics of national importance, such as the coronavirus (COVID-19) pandemic and the cost of living. The OPN has expanded to include questions on other topics of national importance, such as health and the cost of living.For more information about the survey and its methodology, see the gov.uk OPN Quality and Methodology Information (QMI) webpage.Changes over timeUp to March 2018, the OPN was conducted as a face-to-face survey. From April 2018 to November 2019, the OPN changed to a mixed-mode design (online first with telephone interviewing where necessary). Mixed-mode collection allows respondents to complete the survey more flexibly and provides a more cost-effective service for module customers.In March 2020, the OPN was adapted to become a weekly survey used to collect data on the social impacts of the coronavirus (COVID-19) pandemic on the lives of people of Great Britain.

Labour Force Survey Five-Quarter Longitudinal Dataset, April 2016 - June 2017

Abstract copyright UK Data Service and data collection copyright owner.Background The Labour Force Survey (LFS) is a unique source of information using international definitions of employment and unemployment and economic inactivity, together with a wide range of related topics such as occupation, training, hours of work and personal characteristics of household members aged 16 years and over. It is used to inform social, economic and employment policy. The LFS was first conducted biennially from 1973-1983. Between 1984 and 1991 the survey was carried out annually and consisted of a quarterly survey conducted throughout the year and a 'boost' survey in the spring quarter (data were then collected seasonally). From 1992 quarterly data were made available, with a quarterly sample size approximately equivalent to that of the previous annual data. The survey then became known as the Quarterly Labour Force Survey (QLFS). From December 1994, data gathering for Northern Ireland moved to a full quarterly cycle to match the rest of the country, so the QLFS then covered the whole of the UK (though some additional annual Northern Ireland LFS datasets are also held at the UK Data Archive). Further information on the background to the QLFS may be found in the documentation. Longitudinal data The LFS retains each sample household for five consecutive quarters, with a fifth of the sample replaced each quarter. The main survey was designed to produce cross-sectional data, but the data on each individual have now been linked together to provide longitudinal information. The longitudinal data comprise two types of linked datasets, created using the weighting method to adjust for non-response bias. The two-quarter datasets link data from two consecutive waves, while the five-quarter datasets link across a whole year (for example January 2010 to March 2011 inclusive) and contain data from all five waves. A full series of longitudinal data has been produced, going back to winter 1992. Linking together records to create a longitudinal dimension can, for example, provide information on gross flows over time between different labour force categories (employed, unemployed and economically inactive). This will provide detail about people who have moved between the categories. Also, longitudinal information is useful in monitoring the effects of government policies and can be used to follow the subsequent activities and circumstances of people affected by specific policy initiatives, and to compare them with other groups in the population. There are however methodological problems which could distort the data resulting from this longitudinal linking. The ONS continues to research these issues and advises that the presentation of results should be carefully considered, and warnings should be included with outputs where necessary. LFS Documentation The documentation available from the Archive to accompany LFS datasets largely consists of the latest version of each user guide volume alongside the appropriate questionnaire for the year concerned. However, volumes are updated periodically by ONS, so users are advised to check the latest documents on the ONS Labour Force Survey - User Guidance pages before commencing analysis. This is especially important for users of older QLFS studies, where information and guidance in the user guide documents may have changed over time.Occupation data for 2021 and 2022 data filesThe ONS has identified an issue with the collection of some occupational data in 2021 and 2022 data files in a number of their surveys. While they estimate any impacts will be small overall, this will affect the accuracy of the breakdowns of some detailed (four-digit Standard Occupational Classification (SOC)) occupations, and data derived from them. Further information can be found in the ONS article published on 11 July 2023:&nbsp;Revision of miscoded occupational data in the ONS Labour Force Survey, UK: January 2021 to September 2022.2022 WeightingThe population totals used for the latest LFS estimates use projected growth rates from Real Time Information (RTI) data for UK, EU and non-EU populations based on 2021 patterns. The total population used for the LFS therefore does not take into account any changes in migration, birth rates, death rates, and so on since June 2021, and hence levels estimates may be under- or over-estimating the true values and should be used with caution. Estimates of rates will, however, be robust.Main Topics:The five-quarter longitudinal datasets include a subset of the most commonly used variables from the Quarterly Labour Force Survey (QLFS), covering the main areas of the survey
