Brief summary: Russian National Health Telephone Survey (RNHTS) is a public health surveillance study that assesses various health-related quality of life, health-related behavior, and health care utilization indicators on a representative sample of the adult Russian population. All data will be collected via a Computer Assisted Telephone Interview (CATI).

Detailed description: Russian National Health Telephone Survey (RNHTS) is the first public health surveillance study in Russia. The aim of RNTHS is to obtain unique representative data on health-related quality of life, health-related behaviors, and health care utilization indicators for the adult Russian population. Analysis of these indicators provides a detailed outlook on how health is associated with people's well-being, quality of life, and socio-demographic characteristics, which adds to official and aggregated statistics for Russia.

RNHTS consists of five sections. Section 1 includes socio-demographic characteristics of respondents such as their gender, age, marital status, education level, income level, employment status and location. Section 2 measures indicators of general health and health-related quality of life using the 3-level version of the EuroQol-5 Dimension questionnaire (EQ-5D-3L) and the Washington Group Short Set on Functioning questionnaire (WG-SS). Section 3 covers three health-related behaviours of respondents: smoking, drinking alcohol, and physical activity. Section 4 consists of questions about health care utilization in the last 12 months with an emphasis on patient choice between public and private health care. This section also measures how satisfied respondents were with health care services that they used, their unmet needs, and their health care avoidance. Section 5 is modifiable for each round (year) of RNHTS. This version of the protocol describes round 2 of RNHTS. In this round, Section 5 is devoted to measuring prevalence of arthritis in the adult Russian population and how it affects their quality of life as well as to learning about oral health and dental services utilization among Russian adults.

More than 2000 respondents will be randomly selected for RNHTS. All data will be collected using a Computer Assisted Telephone Interview (CATI) system, which allows real-time data capture and consolidation. All interviews will be conducted anonymously. The telephone survey will be conducted by Agency of Social Information St. Petersburg (ASI St. Petersburg). RNHTS data will be analysed using statistical analysis methods which will be presented using summary tables (summary statistics, contingency tables, frequency distributions), correlation coefficients, and estimates of regression models (coefficients, odds ratios, marginal effects). The results of statistical analysis will be compiled in one report with authors' comments on the findings.
