      Abstract

      The purpose of the study was to evaluate the effectiveness of a multicomponent nutrition education program among adults. A pretest—posttest design was used assessing Nutritional Knowledge (NK), BMI, Energy Intake (EI), Physical Activity Level (PAL), Dietary Intake (DI) and attitudes. 353 adults aged 19–55 years (178 control group (CG) and 175 intervention group (IG)) were recruited. IG participants attended nutrition education sessions evaluated through a post-test given at the end of the 12-week program. Statistical tests performed revealed that compared to CG, participants in IG increased fruit intake and decreased intake of snacks high in sugar and fat significantly (p < 0.05). NK and attitudinal scores also increased significantly in the IG (p < 0.05). No intervention effect was found for vegetables intake, EI, BMI and PAL (p > 0.05). Factors influencing NK were age, gender and education level. “Taste” was the main barrier to the application of the nutrition education strategy. Findings are helpful to health practitioners in designing their intervention programs.

      Health literacy and public health: A systematic review and integration of definitions and models

      Background Health literacy concerns the knowledge and competences of persons to meet the complex demands of health in modern society. Although its importance is increasingly recognised, there is no consensus about the definition of health literacy or about its conceptual dimensions, which limits the possibilities for measurement and comparison. The aim of the study is to review definitions and models on health literacy to develop an integrated definition and conceptual model capturing the most comprehensive evidence-based dimensions of health literacy. Methods A systematic literature review was performed to identify definitions and conceptual frameworks of health literacy. A content analysis of the definitions and conceptual frameworks was carried out to identify the central dimensions of health literacy and develop an integrated model. Results The review resulted in 17 definitions of health literacy and 12 conceptual models. Based on the content analysis, an integrative conceptual model was developed containing 12 dimensions referring to the knowledge, motivation and competencies of accessing, understanding, appraising and applying health-related information within the healthcare, disease prevention and health promotion setting, respectively. Conclusions Based upon this review, a model is proposed integrating medical and public health views of health literacy. The model can serve as a basis for developing health literacy enhancing interventions and provide a conceptual basis for the development and validation of measurement tools, capturing the different dimensions of health literacy within the healthcare, disease prevention and health promotion settings.

          Global variability in fruit and vegetable consumption.

          Low fruit and vegetable consumption is an important risk factor for chronic diseases, but for many (mainly developing) countries, no prevalence data have ever been published. This study presents data on the prevalence of low fruit and vegetable intake for 52 countries and for various sociodemographic groups and settings across these countries. Data from 196,373 adult participants from 52 countries taking part in the World Health Survey (2002-2003) were analyzed in the summer of 2008. Low fruit and vegetable consumption was defined according to the WHO guidelines of a minimum of five servings of fruits and/or vegetables daily. Low fruit and vegetable consumption prevalence ranged from 36.6% (Ghana) to 99.2% (Pakistan) for men and from 38.0% (Ghana) to 99.3% (Pakistan) for women. Significant differences in the likelihood of low fruit and vegetable intake between men and women were found in 15 countries. The prevalence of low fruit and vegetable consumption tended to increase with age and decrease with income. Although urbanicity was not associated overall with low fruit and vegetable consumption, urban and rural differences were significant for 11 countries. Overall, 77.6% of men and 78.4% of women from the 52 mainly low- and middle-income countries consumed less than the minimum recommended five daily servings of fruits and vegetables. Baseline global information on low fruit and vegetable consumption obtained in this study can help policymakers worldwide establish interventions for addressing the global chronic disease epidemic.
