OBJECTIVE: To analyse the influence of social and cultural factors in the prevalence of @entity28 in the Spanish adult population aged 25--60 y based on available population data. DESIGN: Pooled analysis of four cross-sectional nutrition surveys. SUBJECTS: A total of 5388 free-living subjects aged 25--60 y, respondents of the Nutritional Surveys carried out in four Spanish regions (Catalunya, Basque Country, Madrid and Valencia) from 1990 to 1994. The samples were pooled together and weighted to build a national random sample. MEASUREMENTS: Weight and height were measured on each individual by trained observers. Age, gender, educational level, occupation, habitat (rural/urban) and region were considered. Obesity was defined as body mass index > or = 30 kg/m(2). The protocol used in each survey was in accordance with the recommendations of the Spanish Society for the Study of Obesity (SEEDO). @entity2357 models were designed to analyse the influence of sociodemographic factors in the prevalence of @entity28 in @entity1 and @entity1 . RESULTS: The prevalence of @entity28 was higher in older age groups in @entity1 and @entity1 , odds ratio (OR) for every 10 y OR=1.40 (95% CI 1.39--1.41) for @entity1 and OR=1.86 (95% CI 1.85--1.87) for @entity1 . @entity2357 analysis adjusted for age showed higher @entity28 rates among low educated @entity1 , OR=1.80 (95% CI 1.78--1.81) in @entity1 and OR=2.36 (95% CI 2.29--2.42) in @entity1 (P<0.001). Among @entity1 the odds ratio for the prevalence of @entity28 in rural areas was OR=1.87 (95% CI 1.86--1.89), compared to cities. The geographical distribution showed higher @entity28 rates in the southeast. CONCLUSION: This study supports that @entity28 is a multifactorial problem. Older @entity1 with low educational level and low income seem to be the most susceptible group to @entity1017 . Therefore, Public Health Programs should consider this type of environmental factor when planning strategies aimed at preventing or reducing the problem of @entity28 in western societies.
