Baromètre Santé Adulte 2021-2022

In 2021-2022, Agence Sanitaire et Sociale Nouvelle Calédonie (ASSNC) is undertaking the "Baromètre Santé Adulte" for the third time. This study is carried out this year in collaboration with WHO and Institut Pasteur de Nouvelle Calédonie (IPNC).

The main objective of this investigation is to describe the current levels of chronic disease risk factors in the adult population of New Caledonia aged from 18 to 64 years old. This study will also help to estimate prevalence of certain diseases (diabetes, hypercholesterolemia, renal failure), seroprevalence of arboviruses (dengue fever, Zika, chikungunya and Ross River) malaria as well as the seroprevalence of SARS-CoV-2.

Repeated regularly, these surveys allow the ASS-NC to capitalize on population indicators, to compare them according to socio-demographic characteristics, to identify groups at risk, to provide changes in health behaviors and to strengthen analytical capacities in order to adapt the guidelines for public policies and prevention programs.

The "Barometre Santé Adulte" is an observational, descriptive and cross-sectional study whose data collection will take place in New Caledonia.

For this study the sampling is based on the 2019 population census, according to a 3-stage stratified sample design. In total, the main sample will consist of approximately 5,500 people (first phase) and the sub-sample will consist of 1,800 people (second phase).

The participation rate is estimated at 60%. Data collection will take place from February to May at the people's place drawn according to two steps:

* Firstly, investigators will carry out a questionnaire with the people who gave their informed consent as well as taking physical measurements: height, weight, abdominal circumference and blood pressure. In addition to the socio-demographic characteristics of the respondents, the questionnaire deals with several health topics: consumption of psychoactive substances, diet, physical activity, health status and access to care, screening, oral health, driving motor vehicle risk, sexual health, mental health, etc. The time taken to complete the questionnaire is estimated at one hour.
* Secondly, and for a sub-sample of 1,800 people, nurses will come back to the people's places who volunteer to take a venous blood test: blood sugar, total cholesterol, HbA1c, serum creatinine, CBC and serology of diseases transmitted by mosquitoes (dengue, chikungunya, Zika and Ross River, malaria).

All the data collected will be entered on a tablet in the eSTEPS application. The analysis of data (R Studio software) and the drafting of the report will be carried out by ASSNC staff. The first results are expected for the second half of 2022.
