ABSTRACT
Introduction: Work environments shape dietary habits, particularly in contexts characterized by job insecurity and limited availability of healthy foods. The Quito Wholesale Market, where formal traders and informal workers converge under demanding conditions, represents a relevant setting to examine the relationship between diet, work, and health.
Objective: To identify predominant dietary patterns among workers at the Quito Wholesale Market and to explore their associations with sociodemographic variables, working conditions, health history, and anthropometric indicators.
Methods: An observational, cross-sectional study with a quantitative approach and a descriptive design including exploratory associative analysis will be conducted. Two non-consecutive 24-hour dietary recalls will be applied, and usual intake will be estimated using the Multiple Source Method. Principal component analysis will be used to identify dietary patterns. Sociodemographic, occupational, health, and anthropometric variables will be included. The estimated sample consists of 548 adult workers, selected through non-probability convenience sampling. Structured questionnaires and standardized measurement procedures will be applied.
Expected results: Predominant dietary patterns are expected to be identified, along with potential associations with occupational, sociodemographic, and health characteristics. Given the study design, these associations will be interpreted as exploratory, without causal inference or population representativeness.
Conclusions: This study will provide descriptive evidence on the relationship between diet and working conditions in a vulnerable urban population and may inform the development of context-specific public health policies and interventions.
