- Can the external environment affect the occupational safety conditions and unsafety behaviours?Publication . Loureiro, I.F.; Rodrigues, Matilde; Vale, C.; Azevedo, R.Portugal is undergoing an economic crisis affecting the European Union since 2007. The financial unsustainability of Portugal required foreign aid and consequently austerity and structural measures have been implemented. These measures are causing negative impacts on the economy income and living conditions of the population of Portugal. Studies in this field can stimulate new challenges in Occupational Safety and Health, as well as can be useful to planning strategies that attempt to minimize this situation. The present study adopted a quantitative methodology using a self-completed question naire named External Environment Questionnaire. The results indicate that the instability experienced by respondents and the organizations that they work for, may contribute to profound changes in the working conditions.
- Determinants of maternal exposure to heavy metals and semi-metals: Focus on diet and lifestylePublication . Guimarães, J.; Bracchi, Isabella; Pinheiro, C.; Vieira, M.I.; Barbosa, M. Oliveira; Almeida, A.; Azevedo, R.; Pinto, Edgar; Pestana, D.; Calhau, C.; Prucha, M. do Carmo; Martins, C.; Dias, C.C.; Azevedo, L.F.R.; Ramalho, C.; Fernandes, Virginia Cruz; Keating, E.; Fernandes, Virgínia; Pinto, EdgarKnowledge on determinants and health risks of toxic metal exposure in pregnancy is scarce in Portugal. This study aims to characterize food and lifestyle determinants of maternal exposure to Lead (Pb), Cadmium (Cd) and Arsenic (As). We included 1111 pregnant women undergoing routine 1sttrimester fetal ultrasound scan between 2018 and 2021 at CHUSJoão (Porto) and Hospital CUF Descobertas (Lisbon), who had single pregnancy and gave informed consent. At this stage, we collected diet and lifestyle information and a random urine sample for Pb, Cd and As quantification by ICP-MS. The majority of the sample had detectable urinary levels of toxic elements (n (%) and median (P25; P75) for Pb, Cd (in ng/g), and As (in μg/ g): 980 (88) and 547.2 (289.1; 975.9), 628 (57) and 142.5 (81.5; 234.9), 1080 (97) and 27.4 (14.9; 51.3), respectively). Cd and As urinary concentrations were positively correlated (r s =0.250, p<0.001). Smoking habits were associated with higher Pb (p=0.034) and Cd (p=0.008) levels and Pb levels had a negative weak correlation with birth head circumference (r s =-0.102; p=0.009). Regarding diet, the frequencies of fish and eggs intake were positively associated with Cd and As levels (p=0.005 and p< 0.001, respectively for fish intake; p=0.030 and p<0.001, respectively, for eggs intake). Women who reported consuming fish or eggs at least four times a week presented median (P25; P75) As levels of 35.2 (21.3; 71.9) or 35.9 (16.8; 57.2) μg/g, respectively. These concentrations exceed the commonly accepted reference range (≥24.0 μg/g), observed in healthy populations. Our results evidence that, in pregnant women, smoking might be a determinant of Pb and Cd exposure and fish and eggs might be relevant determinants of Cd and As exposure. These data stress the need to study the consequences of Pb or As and Cd cumulative exposure on the health of the mother and the offspring.
- Relationship between smartphone use and musculoskeletal symptoms in adolescentsPublication . Santos, Paula Clara; Oliveira, R.; Mesquita, Cristina; Mota, J.; Azevedo, R.; Lopes, SofiaWe are currently facing a society of adolescents who are increasingly dependent on technology, in particular the smartphone, and this phenomenon can even lead to limiting situations in which the person's physical wellbeing is called into question. Intensive use of the smartphone may contribute to a decrease in physical activity and generate musculoskeletal symptoms (MMS).
