- Does diet strictness level during weekends and holiday periods influence 1-year follow-up weight loss maintenance? Evidence from the Portuguese Weight Control RegistryPublication . Jorge, Rui; Santos, Inês; Teixeira, Vitor Hugo; Teixeira, Pedro JorgeThere is not much evidence about how diet strictness during weekends and holidays influence long-term weight loss maintenance. Our aim was to examine how dieting more or less strictly during weekends and holidays (vs. weekdays and non-holiday periods) influence weight loss maintenance. Participants (n = 108) from the Portuguese Weight Control Registry indicated whether they had a more or less strict diet regimen during weekends compared to weekdays. A similar question about holiday and non-holiday period’ diet regimen was answered. Weight and height were measured at baseline and 1y follow-up. A 3% maximum weight variation defined participants as “non-regainers”. General level on dieting strictness on weekends vs. weekdays (r = − 0.28, p < 0.01) and holidays vs. non-holidays (r = − 0.33, p < 0.001) predicted 1y weight change. Participants who reported being less strict on weekends (OR = 0.34, 95% CI: 0.15–0.81) were more likely to be non-regainers when compared with the ones who reported being more strict on weekends. Non-significant results were found during holidays (OR = 0.47, 95% CI: 0.20–1.09). Adopting a less strict diet regimen during weekends, when compared to weekdays, was a behavioral strategy associated with long-term weight management in our sample.
- Exploring hedonic and eudaimonic items of well-being in Mediterranean and non-Mediterranean countries : influence of sociodemographic and lifestyle factorsPublication . Andrade, Vanda; Quarta, Stefano; Tagarro, Marta; Miloseva, Lence; Massaro, Marika; Chervenkov, Mihail; Ivanova, Teodora; Jorge, Rui; Maksimova, Viktorija; Smilkov, Katarina; Ackova, Darinka Gjorgieva; Ruskovska, Tatjana; Philippou, Elena; Deligiannidou, Georgia Eirini; Kontogiorgis, Christos A.; Conesa, María-Teresa García; Pinto, PaulaIncreased understanding of subjective well-being (SWB), as well as factors that influence it, are essential to enhance well-being at the individual and national level. We have applied a hedonic and eudaimonic 9-item composed tool (SWB score) to measure SWB across several Mediterranean (MED) and non-Mediterranean (non-MED) countries, and to explore the association between the SWB score and a range of sociodemographic, health and Mediterranean lifestyle factors. A specifically designed web-based questionnaire was distributed to adult participants (N = 2400) from Spain, Italy, Portugal, Bulgaria and Republic of North Macedonia. Results showed that the SWB score was significantly different across the examined countries with the MED participants displaying slightly higher average scores than the non-MED ones (6.3 ± 1.5 vs. 6.1 ± 1.6, p = 0.002). Several sociodemographic, health status and lifestyle factors displayed a significant but limited association with the 9-item SWB score, with a multiple regression model explaining around 17% of the variance. Nevertheless, our results support that a closer adherence to Mediterranean lifestyle habits—the Mediterranean Diet, spending time with friends, family, and in nature, being active, and getting adequate rest at night—has a positive influence on the 9-item SWB score. Further research is needed to advance the understanding of the measuring and differentiating of SWB across different populations and to establish all the factors that influence it.
- Exploring the validity of the 14-item mediterranean diet adherence screener (MEDAS): a cross-national study in seven european countries around the Mediterranean regionPublication . García-Conesa, María-Teresa; Philippou, Elena; Pafilas, Christos; Massaro, Marika; Quarta, Stefano; Andrade, Vanda; Jorge, Rui; Chervenkov, Mihail; Ivanova, Teodora; Dimitrova, Dessislava; Maksimova, Viktorija; Smilkov, Katarina; Ackova, Darinka Gjorgieva; Miloseva, Lence; Ruskovska, Tatjana; Deligiannidou, Georgia Eirini; Kontogiorgis, Christos A.; Pinto, PaulaThis study provides comprehensive validation of the 14-item Mediterranean Diet Adherence Screener (14-MEDAS) in an adult population from Greece (GR), Portugal (PT), Italy (IT), Spain (SP), Cyprus (CY), Republic of North Macedonia (NMK), and Bulgaria (BG). A moderate association between the 14-MEDAS and the reference food diary was estimated for the entire population (Pearson r = 0.573, p-value < 0.001; Intraclass Correlation Coefficient (ICC) = 0.692, p-value < 0.001) with the strongest correlation found in GR, followed by PT, IT, SP, and CY. These results were supported by kappa statistics in GR, PT, IT, and SP with ≥50% of food items exhibiting a fair or better agreement. Bland–Altman analyses showed an overestimation of the 14-MEDAS score in the whole population (0.79 ± 1.81, 95%Confidence Interval (CI) 0.61, 0.96), but this value was variable across countries, with GR, NMK, and BG exhibiting the lowest bias. Taking all analyses together, the validation achieved slightly better results in the Mediterranean countries but a definitive validation ranking order was not evident. Considering growing evidence of the shift from Mediterranean Diet (MD) adherence and of the importance of culture in making food choices it is crucial that we further improve validation protocols with specific applications to measure and compare MD adherence across countries and to relate it to the health status of a specific population.
- Hábitos alimentares em distintos períodos pandémicos ao longo da história: uma revisão narrativa da literaturaPublication . Monteiro, Catarina; Jorge, RuiA quarentena, voluntária ou obrigatória, suscita transformações inevitáveis no estilo de vida. A presente revisão narrativa da literatura visa estudar os hábitos alimentares adotados durante pandemias e epidemias com repercussões mundiais. Enquanto antigamente as doenças infeciosas eram predominantes em indivíduos desnutridos por escassez de alimento, hoje afetam desnutridos devido a hábitos alimentares excessivos e desequilibrados. A Gripe Espanhola originou grande escassez de alimento e insegurança alimentar. A Gripe das Aves e a Gripe A não afetaram hábitos no consumo da carne e ovos, apesar do impacto no setor alimentar. Tanto a Gripe A como a COVID-19 foram exacerbadas pela elevada prevalência de doenças crónicas, nomeadamente a obesidade. A atuação do nutricionista em contexto pandémico ou epidémico, é crucial por promover, junto da população, a adoção de um estilo de vida saudável, principalmente hábitos alimentares, como medida preventiva.
- Mediterranean diet adherence and subjective well-being in a sample of portuguese adultsPublication . Andrade, Vanda; Jorge, Rui; García-Conesa, María-Teresa; Philippou, Elena; Massaro, Marika; Chervenkov, Mihail; Ivanova, Teodora; Maksimova, Viktorija; Smilkov, Katarina; Ackova, Darinka Gjorgieva; Miloseva, Lence; Ruskovska, Tatjana; Deligiannidou, Georgia Eirini; Kontogiorgis, Christos A.; Pinto, PaulaThe Mediterranean diet (MD) and other lifestyle characteristics have been associated with well-being, a broad multiparameter concept that includes individual’s subjective assessment of their own well-being (SWB). Some studies have suggested that diet influences SWB, thus, this work aimed to add novel information on the association of MD and SWB in a sample of Portuguese adults. Data on sociodemographic, economic, lifestyle, diet, and SWB were collected through a self-filled online questionnaire. MD adherence was assessed by the Mediterranean Diet Adherence Screener (MEDAS) score. Results showed a moderate adherence to the MD in 490 Portuguese adults (mean MEDAS of 7.4 ± 2.1). A higher MD adherence was found to be significantly positively associated with women, employed individuals, a higher number of meals per day, and those with frequent contact with nature (p-value < 0.0025, using Bonferroni adjustment). As a novelty, this study divided the participants into low SWB, medium SWB, and medium to high SWB profiles (3.9 ± 1.0; 6.2 ± 1.0; 8.2 ± 1.3, respectively; p-value < 0.05), which reported significantly increasing MEDAS scores (6.5 ± 2.1; 7.3 ± 2.1; 7.8 ± 1.9; respectively, p-value < 0.05).
- Persistent moderate-to-weak Mediterranean diet adherence and low scoring for plant-based foods across several Southern European countries : are we overlooking the Mediterranean diet recommendations?Publication . Quarta, Stefano; Massaro, Marika; Chervenkov, Mihail; Ivanova, Teodora; Dimitrova, Dessislava; Jorge, Rui; Andrade, Vanda; Philippou, Elena; Zisimou, Constantinos; Maksimova, Viktorija; Smilkov, Katarina; Ackova, Darinka Gjorgieva; Miloseva, Lence; Ruskovska, Tatjana; Deligiannidou, Georgia Eirini; Kontogiorgis, Christos A.; Sánchez-Meca, Julio; Pinto, Paula; García-Conesa, María-TeresaThe Mediterranean diet (MD) has been sponsored worldwide as a healthy and sustainable diet. Our aim was to update and compare MD adherence and food choices across several Southern European countries: Spain (SP), Portugal (PT), Italy (IT), Greece (GR), and Cyprus (CY) (MED, Mediterranean), and Bulgaria (BG) and the Republic of North Macedonia (NMK) (non-MED, non-Mediterranean). Participants (N = 3145, ≥18 y) completed a survey (MeDiWeB) with sociodemographic, anthropometric, and food questions (14-item Mediterranean Diet Adherence Screener, 14-MEDAS). The MED and non-MED populations showed moderate (7.08 ± 1.96) and weak (5.58 ± 1.82) MD adherence, respectively, with significant yet small differences across countries (SP > PT > GR > IT > CY > BG > NMK, p-value < 0.001). The MED participants scored higher than the non-MED ones for most of the Mediterranean-typical foods, with the greatest differences found for olive oil (OO) and white meat preference. In most countries, ≥70% of the participants reported quantities of red meat, butter, sweet drinks, and desserts below the recommended cutoff points, whereas <50% achieved the targets for plant-based foods, OO, fish, and wine. Being a woman and increasing age were associated with superior adherence (p-value < 0.001), but differences were rather small. Our results suggest that the campaigns carried out to support and reinforce the MD and to promote plant-based foods have limited success across Southern Europe, and that more hard-hitting strategies are needed.

- Preditores comportamentais e psicossociais da perda e manutenção do peso perdido a longo prazo: uma revisão conceptual de revisõesPublication . Jorge, Rui; Santos, Inês; Carraça, Eliana Veiga; Teixeira, Vitor Hugo; Teixeira, Pedro Jorge; Associação Portuguesa de NutriçãoPerder e, sobretudo, manter o peso perdido a longo prazo continua a ser um desafio para a maioria dos indivíduos, apesar da investigação emergente nesta área. A identificação de fatores chave na gestão do peso é assim essencial para melhorar a eficácia das intervenções comportamentais de tratamento do excesso de peso e obesidade. Esta revisão conceptual de revisões pretende sumariar o estado da arte no que respeita aos preditores comportamentais e psicossociais da perda e manutenção do peso perdido a longo-prazo, em indivíduos com excesso de peso e obesidade envolvidos em intervenções no estilo de vida. Os principais preditores que explicam o sucesso na perda e manutenção do peso perdido a longo prazo são os que afetam diretamente o equilíbrio energético, seja pelo aumento do gasto energético, através da prática de maiores níveis de atividade física, seja pela redução do aporte energético, através do aumento do aporte proteico e de fibra alimentar em detrimento do aporte de gordura e açúcar. Uma maior perceção de autoeficácia para realizar uma alimentação saudável, praticar atividade física regularmente e gerir o peso, assim como o desenvolvimento de competências autorregulatórias, como a automonitorização do peso e dos comportamentos associados, parecem ser fatores complementares chave. No que se refere a preditores de pré-tratamento, o único que se revela consistentemente associado ao sucesso na gestão do peso a longo prazo é um menor número de tentativas de perda de peso anteriores, provavelmente porque a experiência de repetidas tentativas mal sucedidas pode estar relacionada com um perfil psicológico mais vulnerável ao insucesso, caracterizado por atitudes de ceticismo e passividade.
