Brief Summary

The socioeconomic gradient in health is well known and is partially explained by differences in health-related behaviours across socioeconomic groups. There is reason to believe that the current economic crisis has been contributing to the observed rapid decrease in the adherence to the Mediterranean diet, thus reducing a protective factor against the development of major chronic diseases. This project aims at investigating whether the economic crisis could account for the shifting from the Mediterranean diet. Additionally, it will address variations in inflammation biomarkers (possibly dietary-related) or metabolic phenotypes as useful biological accounts for the decline in the adherence to Mediterranean diet. This project will also test whether for economically weakest people cultural resources could somehow attenuate the impact of material circumstances on lifestyle changes attributable to the economic crisis.

Detailed Description

Specific aims:

Aim 1: To identify population groups differently affected by the economic crisis within the population-based cohort of the MOLI-SANI study recruited in the years 2005-2006 (before economic crisis). This aim will be achieved by a new assessment of self-reported economic difficulties possibly emerged after the recruitment.

Aim 2: To estimate possible changes in dietary and health-related behaviours (with particular focus on the adherence to the Mediterranean diet) in subjects identified in the previous aim as highly or poorly affected by the economic crisis. Inflammatory status and metabolic phenotypes will be assessed in the two groups, recalled in a suitable proportion, to establish a possible link between shifting from the Mediterranean diet and adverse health outcomes. Quality of life and stress status will also be evaluated.

Aim 3: To evaluate in the group more affected by economic constraints whether nutrition knowledge and mass media exposure would account for the decline in the adherence to the Mediterranean diet and consequent changes in inflammatory status and/ or metabolic phenotypes.

Experimental Design Aim 1: Aim 1 will identify two groups of subjects as being most or less affected by the economic crisis. This aim will be reached by recall of 7,000 individuals from the Moli-sani cohort recruited in the years 2005-2006. Subjects will be administered a questionnaire to assess economic constraints likely occurred after the economic crisis onset. The questionnaire will update socioeconomic position and estimate economic constraints, food quality and food expenditure.

Experimental Design Aim 2: Within the two groups identified in aim 1, aim 2 will:

1. Perform a dietary follow up by administering the Italian version of the EPIC questionnaire (9), already used at baseline, to estimate the changes in dietary habits. Lifestyle follow up will be obtained by a validated questionnaire used at baseline.

2. Assess changes in inflammatory status by measurements of the following biomarkers: High-sensitivity C-reactive protein, Interleukin-6, Interleukin-18, Tumor necrosis factor, Plasminogen activator inhibitor-1, VCAM, ICAM, P-selectin, E-selectin, L-selectin, CD40L, adiponectin, platelet and leukocyte counts, lipids, triglycerides, glucose, insulin.

3. Estimate variations in the metabolic phenotypes (prevalence of hypertension, diabetes, obesity, metabolic syndrome, and levels of blood pressure, hip and waist circumferences).

Experimental Design Aim 3: A validated questionnaire on nutrition knowledge and exposure to mass media will be administered. This will allow to retrospectively identify additional subgroups differently exposed to information in order to estimate the role of cultural resources in health-related behavioural changes.
