Abstract

Introduction: In Cuba, the health of the population is a strategic state priority.

Objectives: obtain useful information on the health of the Cuban population aged 6 years and older, linked to non-communicable diseases, their determinants, main causes of morbidity, disability and mortality; to selected health events and identify the perception of risk about them, describe the quality of life related to health and determine the use and characteristics of health services according to sociodemographic variables. Method: Cross-sectional descriptive observational design that included the 15 provinces and the special municipality Isla de la Juventud of Cuba, during 2018. Universe: 10,520,703 people (9,433,849 aged 15 and over). Sample: 20,112 subjects aged 15 and over and 3,222 aged 6 to 14 from 9,756 homes. Selection by stratified multi-stage cluster sampling, all cohabitants aged 6 and over were included. For biochemistry, one subject from 15 years of age and older per household and all those from 6 to 14 years of age were selected. Weights were calculated for each sample and level of analysis, corrections for non-response and population structure; They calculated ratio estimators and 95% confidence intervals for means and proportions; density of risk factors and diseases at the family level taking into account the selection design.

Results: Final sample: 14,339 (76.3%) people aged 15 and over and 1,550 (48.1%) aged 6 to 14 belonging to 7,217 (81.0%) households.

Conclusions: “Good” precision was obtained for the main estimation parameters.
