Brief Summary:
Epidemiologic studies suggest that some nutrients can be affected lung function. Moreover, no previous studies have prospectively evaluated the effect of the Mediterranean dietary pattern in lung function in smokers. Phase II of the RESET study , a clinical trial to evaluate the efficacy of a motivational smoking intervention based on information obtained by spirometry (FIS project PI11/01962).

Condition or disease Intervention/treatment Phase
Pulmonary Function Behavioral: Mediterranean Diet Not Applicable

Detailed Description:

Design: Multicenter randomized controlled trial in primary care. Sample: We will recruit 80 smokers from 35 to 70 years without history of lung disease. Subjects will be randomly assigned to control or intervention group (1:1).

Study variables: We measure socio-demographic, clinical, anthropometry and spirometry data. Food consumption will be evaluated by a semi-quantitative food frequency questionnaire (FFQ), energy expenditure in physical activity by the Minnesota Leisure Time Activity questionnaire and adherence to Mediterranean Diet by a 14-item questionnaire.

Intervention: Nutritional intervention conducted by a dietitian who designs a nutrition program to enhance the traditional Mediterranean diet pattern using new technology as an educational tool in primary care: DIET blog. Participants will be referred to a single annual visit and one group session per year for two years.

Analysis: All analyses will be based on intention-to-treat. The results will be considered clinically relevant when it detects a difference in lung function (decreased FEV1) >10-12 ml/year. A p-value of <0.05 will defined statistical significance.

Primary Outcome Measures :
  1. Changes in lung function [ Time Frame: 2 years ]
    Assess the relationship between lung function and adherence to a Mediterranean Diet and its components


Secondary Outcome Measures :
  1. Lung function and anthropometric parameters [ Time Frame: 2 years ]
    Assess the relationship between lung function and anthropometric parameters such as waist circumference and BMI.

  2. Lung function and effectiveness of a nutritional educational tool 2.0 [ Time Frame: 2 years ]
    To evaluate the effectiveness of using an nutritional educational tool 2.0 to increase adherence to a Mediterranean diet: blog.
