BackgroundThe popularity of botanical products is on the rise in Europe, with consumers using them to complement their diets or to maintain health, and products are taken in many different forms (e.g. teas, juices, herbal medicinal products, plant food supplements (PFS)). However there is a scarcity of data on the usage of such products at European level.ObjectiveTo provide an overview of the characteristics and usage patterns of PFS consumers in six European countries.DesignData on PFS usage were collected in a cross-sectional, retrospective survey of PFS consumers using a bespoke frequency of PFS usage questionnaire.Subjects/settingA total sample of 2359 adult PFS consumers from Finland, Germany, Italy, Romania, Spain and the United Kingdom.Data analysesDescriptive analyses were conducted, with all data stratified by gender, age, and country. Absolute frequencies, percentages and 95% confidence intervals are reported.ResultsOverall, an estimated 18.8% of screened survey respondents used at least one PFS. Characteristics of PFS consumers included being older, well-educated, never having smoked and self-reporting health status as “good or very good”. Across countries, 491 different botanicals were identified in the PFS products used, with Ginkgo biloba (Ginkgo), Oenothera biennis (Evening primrose) and Cynara scolymus (Artichoke) being most frequently reported; the most popular dose forms were capsules and pills/tablets. Most consumers used one product and half of all users took single-botanical products. Some results varied across countries.ConclusionsThe PlantLIBRA consumer survey is unique in reporting on usage patterns of PFS consumers in six European countries. The survey highlights the complexity of measuring the intake of such products, particularly at pan-European level. Incorporating measures of the intake of botanicals in national dietary surveys would provide much-needed data for comprehensive risk and benefit assessments at the European level.

Factor analysis using the correlations between indexes was applied. The correlation with factors and the reliability coefficient were calculated. Setting: A total of 324 healthy undergraduates at the University of Barcelona, Spain, were surveyed. Results: The highest correlations were observed between MDP adherence index and MAI (0?82); MAI and MSDPS (0?80); and MDS and rMED (0?77). Factor analysis showed a hidden common factor that explained over 70 % of the variability (71?03 %). This factor is understood as 'adherence to the Mediterranean diet'. The indexes that showed the highest correlation with this factor were Med-DQI (0?85), MDS (0?84), rMED (0?80) and MAI (0?80). These indexes showed acceptable performance in measuring the adherence to the Mediterranean diet. The components that correlated strongly with this factor were monounsaturated-to-saturated fatty acid ratio (MS ratio), fruit and vegetables. Furthermore, a second common factor was found explaining 18 % of the variability. This second factor is highly positive related to dairy products and lean meat, and negative related to MS ratio. Conclusions: The indexes showed satisfactory performance in assessing adherence to the Mediterranean diet. However, in order to improve the reliability and concordance between the indexes, further studies are required to select the components, the number of components, and the scoring criteria of the indexes to improve their internal consistency.

Higher vertical jumping asymmetries and lower physical performance are indicators of increased injury incidence in youth team-sport athletes.

BackgroundThe use of food supplements containing botanicals is increasing in European markets. Although intended to maintain the health status, several cases of adverse effects to Plant Food Supplements (PFS) have been described.ObjectivesTo describe the self-reported adverse effects collected during the European PlantLIBRA PFS Consumer Survey 2011–2012, with a critical evaluation of the plausibility of the symptomatology reported using data from the literature and from the PlantLIBRA Poisons Centers' survey.Subjects/SettingFrom the total sample of 2359 consumers involved in the consumers' survey, 82 subjects reported adverse effects due to a total of 87 PFS.ResultsCases were self-reported, therefore causality was not classified on the basis of clinical evidence, but by using the frequency/strength of adverse effects described in scientific papers: 52 out of 87 cases were defined as possible (59.8%) and 4 as probable (4.6%). Considering the most frequently cited botanicals, eight cases were due to Valeriana officinalis (garden valerian); seven to Camellia sinensis (tea); six to Ginkgo biloba (Maidenhair tree) and Paullinia cupana (guarana). Most adverse events related to the gastrointestinal tract, nervous and cardiovascular systems.ConclusionsComparing the data from this study with those published in scientific papers and obtained by the PlantLIBRA Poisons Centers' survey, some important conclusions can be drawn: severe adverse effects to PFS are quite rare, although mild or moderate adverse symptoms can be present. Data reported in this paper can help health professionals (and in particular family doctors) to become aware of possible new problems associated with the increasing use of food supplements containing botanicals.
