ECATD-CAD. Estudo sobre o consumo de Álcool, Tabaco, Drogas e outros Comportamentos Aditivos e Dependências. Portugal 2024. Relatório Regional
Publication . Lavado, Elsa; Calado, Vasco; ICAD
O presente documento é relativo ao Estudo sobre o consumo de Álcool, Tabaco, Drogas e outros Comportamentos Aditivos e Dependências (ECATD-CAD).
o ECTAD-CAD resulta da aplicação do questionário ESPAD em amostras representativas dos alunos do ensino público com idades entre os 13 e 18 anos, sendo que a presente edição foi a primeira cuja recolha de dados se fez online.
Dos resultados do ECAT-CAD é de salientar uma descida generalizada, dos comportamentos aditivos entre alunos do ensino público. A mesma tendência verifica-se também no plano regional.
Spatiotemporal variables comparison between drop jump and horizontal drop jump in elite jumpers and sprinters
Publication . Montoro-Bombú, Raynier; Miranda-Oliveira, Paulo; Valamatos, Maria João; João, Filipa; Buurke, Tom J. W.; Santos, Amândio Cupido; Rama, Luis
Background: General expectations speculated that there are differences between drop jump (DJ) and horizontal drop jump (HDJ) exercises. While these criteria may be valid, we have yet to find a report that explores these differences in competitive level athletes.
Objective: The study aimed to compare spatiotemporal variables in the drop jump (DJ) vs. the horizontal drop jump (HDJ) in elite jumpers and sprinters.
Methods: Sixteen international-level male athletes performed two DJ attempts at different fall heights 0.3, 0.4, and 0.5 m (DJ30, DJ40, and DJ50), and after 2 h, they performed two HDJ attempts (HDJ30, HDJ40, HDJ50). All jumps were performed on a Kistler force plate. The variables analyzed were ground contact time (GCT), flight time (FT), eccentric phase time, concentric phase time, and time to peak concentric force.
Results: The GCT was found to be significantly shorter in DJ vs. HDJ (Z = 4.980; p = 0.0001; ES = 3.11). FT was significantly lower in DJ30 versus HDJ30 (Z = 4.845; p = 0.0001, d = 3.79), but significantly higher in DJ40 vs. HDJ40 (Z = 4.437; p ≤ 0.0001, d = 3.70) and in DJ50 vs. HDJ50 (Z = 4.549; p ≤ 0.0001, d = 4.72).
Conclusions: It is concluded that the HDJ requires more time for force production, that the eccentric component requires more time than the concentric and that it is not recommended to use the HDJ over the DJ for reactive purposes. This is the first study that comprehensively compare the differences between DJ and HDJ, which will assist coaches and researchers in the design of future training strategies.

Socio-economic inequalities in oral health among Portuguese older adults : a cross-sectional study
Publication . Santos, Inês Caetano; Canales, Giancarlo De la Torre; Lopes, David G.; Mendes, José João; Polido, Mário; Manso, Ana Cristina; Canhão, Helena
Background: Although the oral health status has improved in developed countries in recent years, oral diseases are still unequally distributed across socio-economic groups. Research on the impact of socio-economic factors on oral health care among older adults in Europe, including Portugal, remains limited. The main aim of this study was to investigate the association between socio-economic factors and oral health indicators in Portuguese older adults.
Methods: This retrospective cross-sectional study analyzed data from 915 participants (aged 65 years and older) from the third wave (2015–2016) of the Epidemiology of Chronic Diseases Cohort Study (EpiDoC), a population-based study. Socio-economic and demographic information, general health-related characteristics and oral health data (prosthetic need, oral hygiene frequency, and last dental procedure) were collected by questionnaire. Multivariate logistic and multinomial regression models analyzed the associations between socio-economic factors and oral health indicators.
Results: Participants with lower education level, perceived lower income and a fewer number of private sector appointments were more likely to have poor oral health (need for prosthetic treatment, less frequent oral hygiene, and tooth extraction as last dental procedure). Other factors found to be associated with oral health were sex, age, geographical area, smoking habits, and body mass index.
Conclusions: Socio-economic factors were associated with oral health in Portuguese older adults. These findings may contribute to future national public health strategies by expanding oral health services to ensure better access and coverage for at-risk groups.
Detection and quantification of selected cannabinoids in hair samples by liquid-liquid extraction and LC-MS/MS
Publication . Antunes, Mónica; Simões, Susana; Fonseca, Suzana; Franco, João; Barroso, Mário; Gallardo, Eugenia
Cannabis remains the most used illicit drug worldwide, with rising use linked to medical and recreational decriminalization. This has driven the development of analytical techniques to detect cannabinoids in biological matrices. Hair offers key advantages due to its non-invasive collection, extended detection window, stability, and easy storage. This study presents the development and validation of a robust method for extracting natural cannabinoids from hair, following ANSI/ASB 2019, FDA, and Society of Hair Testing guidelines. Hair samples were washed with methanol and cut into small pieces. Approximately 20 mg of hair was incubated with 1 M NaOH and methanol (30 min, 50 °C). The mixture was acidified with acetic acid and underwent liquid-liquid extraction using hexane/ethyl acetate (90/10, v/v). The organic phase was evaporated and reconstituted in 1-pentanol/methanol (50/50, v/v). Analysis was conducted by LC-MS/MS using multiple reaction monitoring (MRM) and triple-stage mass spectrometry (MS³). The method was selective, specific, precise, and linear, with working ranges of 5-2000 pg/mg for THC, CBN, and CBD; 50-2000 pg/mg for THC-OH; and 0.2-20 pg/mg for THC-COOH. Ion suppression was observed but did not affect sensitivity, with LLOQs and LODs from 0.2 to 50 pg/mg. Over 25 hair samples from university students tested positive for cannabis. THC ranged from 5.9 to 2430.7 pg/mg; one sample had THC-OH above LLOQ (61.4 pg/mg); THC-COOH ranged from 0.3 and 36.4 pg/mg; CBN from 5.7 to 461.0 pg/mg; and CBD from 5.7 to 850.2 pg/mg. Results aligned with self-reported use, confirming the method's forensic suitability.
