Abstract
In this qualitative study, we explored Portuguese adolescents' perceptions of diet, sustainability, and health through six focus group discussions (FGDs). Fifty-five adolescents (10-18 years) participated. FGDs focused on sustainability in food choices and its health impact, with our primary interest in their perceptions. Results showed a limited comprehension of "sustainable/sustainability," especially among younger participants. Those aware of sustainability recognized its diverse aspects, including health, economic, and ecological domains. Some adolescents recognized the link between health and sustainability in their diets, emphasizing the need for food literacy. These findings emphasize the importance of public health and sustainable policies among Portuguese adolescents.

Abstract
Broad variations in dietary and physical activity patterns are part of nutritional transition concept. An additional nutritional transition has as main characteristic the change of consumption of processed foods for ultra-processed foods (UPF). This study aims to evaluate trends of UPF availability in Portuguese population and its association with diet-related non-communicable diseases (NCD) health indicators. This ecological study used data from the Household Budget Surveys conducted by the National Statistics Institute each 5 years within a national representative sample of households. The percentage of UPF was calculated based on the total daily amount of food and beverages available per capita (in grams). Data from the years 1990, 1995, 2000 and 2005 were used, which were retrieved from DAFNE-Anemos Software. NCD age-standardised mortality, prevalence and incidence were obtained from the Global Burden of Disease database, for the years 2000, 2005, 2010 and 2015. Between 1990 and 2005, the UPF availability increased from 3·9 % to 13·8 %. Over the years, almost all food and beverages categories increased the UPF availability contribution, mainly noticeable for milk, sugar, cereal and meat products. Positive correlations were observed between UPF availability and digestive diseases both in prevalence (r = 0·062; P = 0·037) and incidence (r = 0·005; P = 0·010) measures. Neoplasms incidence also showed positive correlation with UPF availability (r = 0·002; P = 0·012). Trends in UPF availability in Portugal increased exponentially. At the same time, there is a trend towards a decrease in unprocessed and processed food availability. The Portuguese population should be made aware of the health risks resulting from excessive consumption of UPF.

Neurodevelopment and Dietary Intake in Toddlers-A Cross-Sectional Study from the Healthy Children 2021 Project. Nutrients 2023; 15:5105. [PMID: 38140364 PMCID: PMC10745499 DOI: 10.3390/nu15245105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 12/06/2023] [Accepted: 12/12/2023] [Indexed: 12/24/2023] Open
Abstract
Little is known about the potential associations between neurodevelopment, dietary diversity and food processing in the toddler period. This study aimed to estimate the association between these dietary quality dimensions and neurodevelopment in toddlers. Data for this cross-sectional analysis came from the Healthy Children 2021 project and included 212 toddlers (51.9% females, aged 12-36 months) from 15 Portuguese childcare centers. Neurodevelopment was assessed through Bayley Scales of Infant and Toddler Development. Dietary intake was gathered by a two-day non-consecutive dietary recall. The food items were categorised with NOVA classification. Dietary diversity was explored through Minimum Dietary Diversity (MDD). Logistic regression models adjusted for potential confounders were performed. Girls with a higher energy contribution of unprocessed/minimally processed foods and with an above median MDD score had higher odds of achieving a higher neurodevelopment score (aOR:1.04; 95%CI 1.01; 1.08 and aOR:2.26; 95%CI 1.01; 5.06, respectively); no significant association was observed in boys. Our findings suggest that these dietary dimensions are associated with a higher neurodevelopment in toddler girls. This should be further studied as a possible early link between dietary factors and neurodevelopment. Promotion of healthy eating can be promising in improving neurocognitive development and might help to introduce public health recommendations for toddlers' nutrition.

Comparison of habitual and meal-specific dietary patterns identified by latent class analysis and confirmatory factor analysis in adults: A cross-sectional study. Nutrition 2023; 115:112185.

Abstract
OBJECTIVE The aim of this study was to compare characteristics of habitual and meal-specific dietary patterns identified by latent class analysis (LCA) and confirmatory factor analysis (CFA). METHODS Participants included 778 adults selected for the present cross-sectional study from local health care centers in Tehran, Iran. Three 24-h dietary recalls evaluated dietary intake. LCA was used to group study participants into exclusive subgroups of individuals with similar patterns of dietary intake. CFA was applied to identify patterns of habitual and meal-specific dietary intake. Analysis of variance was used to compare the average scores of habitual and meal-specific CFA-derived dietary patterns across classes identified by LCA. RESULTS Using habitual dietary intake, CFA grouped correlated food items into three major factors: fruits and vegetables, mixed, and Western dietary patterns. LCA grouped study participants with similar patterns of habitual intake into four subgroups of individuals: fruits and vegetables, mixed, Western, and low consumer classes. LCA-fruits and vegetables, LCA-Western, and LCA-mixed classes had, respectively, higher mean scores of CFA-fruits and vegetables, CFA-Western, and CFA-mixed dietary patterns compared with other classes (P < 0.001). Similar findings were observed for meal-specific dietary intake, where classes identified by LCA had the highest mean scores of their corresponding dietary pattern identified by CFA. CONCLUSION Habitual and meal-specific classes identified by LCA were well characterized by the dietary patterns derived by CFA, suggesting that LCA may be an appropriate statistical approach to classify study participants with similar patterns of intake into exclusive subgroups of individuals.

Abstract
Socioeconomic factors and food insecurity play a fundamental role in the food choices of adolescents, and in addition to influencing access to food, they also have significant effects on dietary patterns. The objectives of this study were to identify the dietary patterns of adolescents through the application of latent class analysis and to evaluate their association with socioeconomic variables and food insecurity. This cross-sectional study was conducted with adolescents aged between 11 and 17 years from public schools. Latent class analysis was used to identify the dietary patterns. Associations between socioeconomic factors, food insecurity and dietary patterns were assessed using multinomial logistic regression (odds ratio (OR); 95% confidence interval (CI)). Among the 1215 participants in the study, four dietary patterns were identified: "Mixed", "Low consumption", "Prudent" and "Diverse". A "Diverse" dietary pattern was associated with a lower economic stratum (OR:2.02; CI:1.26-3.24). There was no association between food insecurity and identified dietary patterns. These results highlight the importance of promoting healthy eating in this age group at all socioeconomic levels, especially the lowest level.
