Factors influencing dietary inequalities among adolescents in Madrid and Bilbao: a qualitative research project.

Objective: To describe the design and methodology of a qualitative study to explore the main factors influencing dietary inequalities in adolescents in Madrid and Bilbao, Spain.

Method: The study area included six neighborhoods (three in each city) of different socioeconomic status (SES): low, medium, and high. We sampled 12 secondary schools (six in each city: two per socioeconomic level).

Conducting member checking within a qualitative case study on health-related behaviours in a large European city: Appraising interpretations and co-constructing findings.

Although member checking is a well-established strategy for appraising credibility, there is a lack of research reporting procedures and outcomes when using this strategy. In recent years, scholars have implemented new member checking strategies along with several epistemological stances. In this work, researchers conducted member checking in three neighbourhoods with different socioeconomic status in Madrid, Spain.

Qualitative examination of the perceived effects of a comprehensive smoke-free law according to neighborhood socioeconomic status in a large city.

Smoke-free legislations aim to protect non-smokers from second-hand smoke (SHS) exposure and improve population health outcomes. The aim of this study was to explore residents' perceptions to understand how people living in distinctive SES neighborhoods are differently affected by comprehensive smoke-free laws in a large city like Madrid, Spain. We conducted a qualitative project with 37 semi-structured interviews and 29 focus group discussions in three different SES neighborhoods within the city of Madrid.
