Self-perception of primary health-care staff about physical activity on prescription: A qualitative semi-structured interview.

OBJECTIVE: This study aimed to analyze the self-perception at primary health-care (PHC) nurses and general practitioners (GPs) toward PAP implementation in PHC centers. MATERIAL AND METHODS: Two semi-structured group interviews were performed separately, with five GPs and nurses working in the PHC system in the region of Madrid (Spain). An expert psychologist guided each semi-structured session. The interviews were transcribed verbatim and consensually analyzed using a content analysis. RESULTS: Half of the PHC staff considered themselves physically active and were convinced that physically active staff behavior could facilitate PAP with patients. Both GPs and nurses showed a lack of knowledge of exercise prescription but were interested in PAP and motivational training courses, as well as leadership or to collaborate under a multidisciplinary or interdisciplinary PAP approach. Some of the most relevant self-perceived PAP barriers were a confident method to measure sedentary and physical activity levels. Besides lack of staff awareness, time of consultation, and improving local community relationships and PAP policies strategies. CONCLUSIONS: There are some common self-perceptions, barriers, and facilitators among PHC nurses and GPs for PAP implementation. Following a socio-ecologic approach, this organizational data provides further insight to design a future cost-effective policy strategy to improve patient health and health-care system sustainability.

Validation of a food frequency questionnaire in Spanish patients with familial hypercholesterolaemia.

BACKGROUND AND AIMS: The aim of this study is to validate a semi-quantitative Food Frequency Questionnaire (FFQ) used for general population in Spain, in patients with familial hypercholesterolaemia (FH). SUBJECTS AND METHODS: Subjects with genetic diagnosis of FH were randomly selected from the Spanish FH Registry. They completed an FFQ based in 113 food items at inclusion (FFQ1) and after 1 year (FFQ2), and a 3-day dietary records (DR) every 3 months. Detailed instruction about how to register foods and beverages was given by a trained nutritionist. Each DR and FFQ was systematically coded, and the daily nutrients intake in absolute, percentage and nutrient density terms were estimated using a software system based on food composition tables. Pearson correlation coefficient was calculated with correction-repeated measurements to assess the reproducibility of both FFQ and the four 3-day DRs, as well as the validity of FFQ comparing to the mean of 3 days' DR. RESULTS: A total of 112 subjects (58 females and 54 males, aged 43 ± 16 years) finished the study. There were no differences between FFQ1, FFQ2 and mean FFQ (FFQa) in mean absolute and percentage values of selected daily nutrients' intake. Comparison between FFQ1, FFQ2, FFQa and the mean of four 3-day DRs was statistically significant in all absolute values, but not in percentage or nutrient density terms. Corrected Pearson correlation coefficient ranged from 0.470 to 0.952 for mean values of all nutrients, except alcohol. CONCLUSION: This study demonstrated that FFQ is a reliable tool to assess the dietary pattern in FH patients.

Mediterranean diet, moderate-to-high intensity training, and health-related quality of life in adults with metabolic syndrome.

BACKGROUND: Much recent research has focused on the benefits of the Mediterranean diet on risk factors of metabolic syndrome (MetS). In addition numerous investigations have also demonstrated that moderate and high-intensity endurance training may induce greater beneficial adaptations in body composition and cardiometabolic risk than low-intensity endurance training. How a model of Mediterranean diet with and without moderate-to-high intensity training influences health-related quality of life (HRQoL) and physical fitness in MetS patients is unknown. DESIGN AND METHODS: A total of 45 sedentary MetS males and females (50⊟66 years) were randomly divided into two groups: (a) hypocaloric, normoproteic Mediterranean diet (MeD); and (b) the same diet plus periodized moderate-to-high intensity training (MeDE) for 12 weeks. HRQoL (EuroQol and SF-36 questionnaires), fitness, response to submaximal exercise, and risk factors of MetS were determined before and after treatment. RESULTS: MeD improved some physical and mental domains of HRQoL (physical function, vitality, general physical health, emotional role, and self-perception of health) and resulted in weight loss and improvement of MetS risk factors (intra-group p < 0.05). Moreover, the MeDE intervention resulted in greater improvement in these domains and the improvement of other HRQoL components (physical role, bodily pain, social function, and health profile). MeDE increased physical fitness, resulted in a better physiological response to submaximal effort and caused a greater weight loss (intra-group and inter-group, p < 0.05). CONCLUSIONS: A model of hypocaloric Mediterranean diet combined with periodized moderate-to-high intensity training may lead to greater improvement in HRQoL through a greater effect on physical and functional fitness, bodyweight, and risk factors than diet alone.
