Towards an integrated multidisciplinary approach to decrease the risk of malnutrition in home care and nursing home settings
Background: Malnutrition often remains undetected in older persons, leading to increased health problems and comorbidity, prolonged hospital stays and readmission. Since malnutrition is a multi-factorial condition, a multidisciplinary and integrated approach is recommended for screening and treatment and this is especially the case in community care, where exchange of health information is often challenging. Methods: Recently, the Global Leadersh…

Measurement of food literacy among the adult population in urban Uganda and Kenya: Development and validation of an East African food literacy scale
Objective: Food literacy (FL) is a potential approach to address the nutrition transition in Africa, but a validated tool is lacking. We developed and validated a scale to assess FL among Ugandan and Kenyan adult populations. Design: A mixed-method approach was applied: (1) item development using literature, expert and target group insights, (2) independent country-specific validation (content, construct, criterion and concurrent) and (3) synchro…
Dietary intake, physical activity and sedentary behavior and association with BMI during the transition to parenthood: A prospective dyadic study
Introduction: Little is known on how diet, physical activity (PA) and sedentary behavior (SB) changes during pregnancy and after childbirth in primiparous couples. Moreover, it is unclear how potential behavioral changes are associated with changes in BMI. This study examined changes in diet, PA and SB, and their association with changes in BMI in couples transitioning to parenthood. Methods: Dietary intake (FFQ), PA, SB (both Actigraph GT3X acce…
Machine learning techniques for the identification of risk factors associated with food insecurity among adults in Arab countries during the Covid-19 pandemic
The ML algorithms seem to be an effective method in early detection and prediction of food insecurity and can profoundly aid policymaking. The integration of ML approaches in public health strategies could potentially improve the development of targeted and effective interventions to combat food insecurity in these regions and globally
Association between perceived partner support and lifestyle in mother-father dyads expecting a first child
Background A healthy lifestyle during pregnancy is important for the health of mother and child. However, unfavorable physical activity (PA) and dietary changes are observed in pregnant women and their partner. Partner's influence on lifestyle has been reported by expectant women and men. The first aim was to analyze associations between perceived partner support on expectant parents own as well as their partner's moderate-to-vigorous intensity P…
The conceptual framework for a combined food literacy and physical activity intervention to optimize metabolic health among women of reproductive age in urban Uganda
The intervention is novel, based on a holistic food literacy model. The intervention is built on determinants specific to urban Uganda, evidence based behavioural change theoretical models and techniques, detailing the hypothesised behavioural change mechanism. If effective, an evidence-based intervention will become available for reference in urban Uganda
Motivations for nutrition information-seeking behavior among Belgian adults: A qualitative study
Our results indicate that beneath the surface of a more apparent need for nutrition information lies a range of motivations demonstrating that nutrition information serves more complex needs than simply information needs. To improve the efficacy of future nutrition education efforts, communication strategies must be tailored to a diverse range of motivations

Dreaming of effective diet change? Motivation, emotions, and dietician presence can all matter
The objective of this study is to verify the relevance of motivational and emotional factors, as well as dietician presence in relation to the optimization of the dietary pattern-change process. This study was carried out with an on-line survey, including 341 respondents, almost half of whom were consulted by a dietician. Two measures were applied to evaluate the effectiveness of the dietary pattern-change among participants. The first of these m…
Determinants of dietary and physical activity behaviours among women of reproductive age in urban Uganda, a qualitative study
Objective: To explore determinants of dietary and physical activity behaviours among women of reproductive age. Design: Data were collected through focus group discussions (FGD). The FGD guide was based on a modified theoretical framework; theory of planned behaviour was incorporated with constructs of health belief model, precaution adoption process model, social cognitive and social support theory. Discussions were audio recorded, transcribed v…
Relevance of European alignment for micronutrients' recommendation regarding pregnant and lactating women, infants, children and adolescents: An insight into preliminary steps of Eurreca
The European Commission (EC) recognized in 2005 the call for a Network of Excellence on ‘nutrient status and requirements of specific vulnerable population groups’, in order to harmonize micronutrient recommendations across Europe as a result of the considerable variations within the European countries (Doets et al. 2008). These large disparities in micronutrient intake recommendations are attributed to different approaches, lack of transparency …
Determinants of ferritin and soluble transferrin receptors as iron status parameters in young adult women
Objective To investigate associations between nutritional and non-nutritional variables and Fe status parameters, i.e. serum ferritin and soluble transferrin receptors (sTfR). Design Cross-sectional design. Fe status parameters were determined on a fasting venous blood sample. Nutritional variables were assessed using a 2 d food record and non-nutritional variables by a general questionnaire. A general linear model was used to investigate associa…
