The Scottish Health Survey (SHeS) series was established in 1995. Commissioned by the Scottish Government Health Directorates, the series provides regular information on aspects of the public's health and factors related to health which cannot be obtained from other sources. The SHeS series was designed to:estimate the prevalence of particular health conditions in Scotland;estimate the prevalence of certain risk factors associated with these health conditions and to document the pattern of related health behaviours;look at differences between regions and between subgroups of the population in the extent of their having these particular health conditions or risk factors, and to make comparisons with other national statistics for Scotland and England;monitor trends in the population's health over time;make a major contribution to monitoring progress towards health targets.Each survey in the series includes a set of core questions and measurements (height and weight and, if applicable, blood pressure, waist circumference, urine and saliva samples), plus modules of questions on specific health conditions that vary from year to year. Each year the core sample has also been augmented by an additional boosted sample for children. Since 2008 NHS Health Boards have also had the opportunity to boost the number of adult interviews carried out in their area. The Scottish Government Scottish Health Survey webpages contain further information about the series, including latest news and publications. The Scottish Health Survey 2022 (SHeS22) is the eighteenth survey in the series. There were two phases to the data. During Phase 1 for the Core sample, potential participants were contacted by letter and recruited to participate by interviewers knocking on their door, in what is termed a 'knock-to-nudge' methodology. Interviews were conducted by telephone and an online or paper self-completion questionnaire. For any interviews undertaken by telephone, no height and weight measurements or biological measures could be taken. The Core sample Phase 2 began in May 2022. Potential respondents were again contacted by letter but were then invited to take part in an in-home interview. A telephone contingency was retained for respondents unwilling to have the interviewer enter their home due to health concerns. Between March and July 2022, participants from the child boost sample continued to be invited to opt in via letter, with interviewer undertaken by telephone with an online/paper self-completion. Fieldwork for the child boost sample was suspended in August 2022 to allow the transition to the second phase (from September 2022) which utilised a sample linked to the Community Health Index (CHI) database. Potential respondents were again contacted by letter but were then invited to take part in an in-home interview. Topics covered included household composition, demographics (including ethnicity, religion, educational background and economic activity), general health including caring, mental health and wellbeing, cardiovascular disease, respiratory disease and asthma, chronic pain, physical activity, eating habits, fruit and veg consumption, smoking and drinking, dental health, COVID-19 and self-reported height and weight measurements. The study also includes combined datasets covering 2021/2022, 2018/2019/2021/2022 and 2018/2022. They contain information from the household questionnaires, main individual schedules and self-completions. The combined datasets have been provided to give a larger base for the analysis of variables. The individual year datasets should be used for the analysis of individual years, including comparisons between years.
