- Obesidade na gravidez: fundamentos básicos para prescrição de exercícioPublication . Bernardo, Diana Filipa Salvador; Carvalho, Carlos Manuel Baptista; Mota, Jorge; Santos, Paula ClaraAs diretrizes internacionais para a atividade física durante a gravidez recomendam unanimemente a prática de pelo menos 150 minutos por semana de atividade física de intensidade moderada para mulheres grávidas sem contraindicações. No entanto, como a obesidade se está a tornar cada vez mais prevalente em mulheres em idade reprodutiva e mulheres grávidas, é importante compreender as alterações anatomofisiológicas e as consequências da obesidade na prescrição de exercício físico durante a gravidez. Este capítulo tem como objetivo descrever e resumir as alterações fisiológicas em grávidas com obesidade, comparar as diretrizes internacionais de exercício físico durante a gravidez em mulheres com obesidade e estabelecer indicações específicas para a prática de exercício físico.
- Vitamin D intake and cardiometabolic: risk factors in adolescentsPublication . Moreira, Carla; Moreira, Pedro; Abreu, Sandra; Santos, Paula Clara; Moreira-Silva, Isabel; Póvoas, Susana; Mota, Jorge; Santos, RuteA growing body of research suggests that vitamin D might play an important role in overall health. No data exist on vitamin D intake for the Azorean adolescent population. The purpose of this study was to assess vitamin D intake and investigate a possible association between vitamin D intake and cardiometabolic risk factors in Azorean adolescents. A cross-sectional school-based study was conducted on 496 adolescents (288 girls) aged 15–18 years from the Azorean Islands, Portugal. Anthropometric measurements (waist circumference and height), blood pressure (systolic), and plasma biomarkers [fasting glucose, insulin, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TGs)] were measured to assess metabolic risk. Homeostasis model assessment (HOMA), TC-to-HDL-C ratio, and waist-to-height ratio were calculated. For each of these variables, a Z-score was computed by age and sex. A metabolic risk score was constructed by summing the Zscores of all individual risk factors. High risk was considered when the individual had ‡ 1 standard deviation(SD) of this score. Vitamin D intake was assessed with a semiquantitative food frequency questionnaire. Participants were classified into quartiles of vitamin D intake. Logistic regression was used to determine odds ratios for high cardiometabolic risk scores after adjusting for total energy intake, pubertal stage, fat mass percentage, and cardiorespiratory fitness. Mean (SD) vitamin D intake was 5.8 (6.5) mg/day, and 9.1% of Azorean adolescents achieved the estimated average requirement of vitamin D (10 mg/day or 400 IU). Logistic regression showed that the odds ratio for a high cardiometabolic risk score was 3.35 [95% confidence interval (CI) 1.28–8.75] for adolescents in the lowest vitamin D intake quartile in comparison with those in the highest vitamin D intake quartile, even after adjustment for confounders. A lower level of vitamin D intake was associated with worse metabolic profile among Azorean adolescents.
- Atividade Física na GravidezPublication . Santos, Paula Clara; Mota, Jorge; Félix, José Manuel SousaA atitude perante a atividade física (AF) durante a gravidez mudou radicalmente nos últimos trinta anos (Charlesworth, 2011). Os nossos antepassados tratavam a mulher grávida como se estivesse doente, sendo aconselhada a descansar e a evitar exercícios (Duncombe et al., 2009). A evidência científica suporta cada vez mais a importância da AF para a saúde individual (Duncombe et al., 2009) e comunitária (Beaglehole et al., 2011). Da pesquisa efetuada, não foram encontrados estudos que mostrassem efeitos negativos da AF de moderada intensidade durante o período gravídico (Da Costa, 2003). Atualmente, existem recomendações para a prática da AF durante a gravidez, pelos benefícios demonstrados, tanto para a mulher como para o bebé (Physical activity guidelines for Americans, 2008). O American College of Obstetricians and Gynecologists (ACOG) em 2002, emanou orientações para que as mulheres grávidas, sem complicações obstétricas, adotem as mesmas recomendações de exercício físico que as das mulheres não grávidas. Da mesma forma, o Centers for Disease Control and Prevention (CDC) e o United States Department of Health and Human Services (USDHHS), 2009 também recomendam a AF durante a gravidez. [...]
- Feasibility, clinical efficacy, and maternal outcomes of a remote exercise program in pregnant women with obesity: The GROB randomized control pilot studyPublication . Bernardo, Diana; Bobadilla-Agouborde, Carolina; Festas, Clarinda; Carvalho, Carlos; Abdalla, Pedro Pugliesi; Amezcua-Prieto, Carmen; Naia-Entonado, Zeltia; Mesquita, Cristina; Mota, Jorge; Santos, Paula ClaraObesity is common in women of reproductive age and increases the risk during pregnancy. Exercising during this period reduces health complications. Home e-health programs are effective in overcoming exercise barriers as pregnant women use technology and the internet for health information. Methods: A single-blind randomized controlled feasibility study with pregnant women with obesity (body mass index [BMI] ≥≥30 kg/m22) was conducted in the University Hospital Center of São João between January and April 2023. Pregnant women were randomized to a control group with standard care and to an experimental group with 8-week remote exercise program using a Phoenix® biofeedback device. Feasibility outcome measures were recruitment rate (≥≥35%), loss to follow-up (≤≤15%), and program fidelity (≥≥1 session/week). Secondary outcomes were evaluated through Pregnancy Physical Activity Questionnaire, Oswestry Index on Disability, and weight assessments at baseline and at the end of the program. Results: Of the 63 eligible participants, 24 (38.1%) were successfully randomized and completed the baseline assessment. Of these, 3 (4.8%) from experimental group did not perform the initial onboarding. The control group had 8.3% of follow-up losses and for the experimental group there were no follow-up losses. Program fidelity (mean ≥≥1 session/week) was fulfilled by 66.7% of successfully randomized participants. Regarding secondary outcomes assessed between baseline and the 8th week, experimental group compared to control group had higher levels of physical activity for sports activities, a lower level of inactivity, and lower disability rates caused by low back pain. Conclusions: Based on the recruitment rate, losses to follow-up, and fidelity rate, the GROB (obesity in pregnancy) study was deemed feasible and worthy of consideration for a larger study. Moreover, the GROB study has the potential to improve maternal outcomes by reducing sedentarism and disability caused by low back pain.
- Relationship between the use of new technologies and musculoskeletal symptoms in children and adolescentsPublication . Santos, Paula Clara; Lopes, Sofia; Oliveira, Rosa; Santos, Helena; Mota, Jorge; Mesquita, CristinaChildhood and adolescence are determinants of musculoskeletal development, and the attitudes and habits adopted during these periods can have repercussions in adult life. The increasing use of technologies is becoming more worrying due to the sustained and prolonged postures due to the use of these devices and the consequent impact on musculoskeletal health.
- Cardiorespiratory fitness is negatively associated with metabolic risk factors independently of the adherence to a healthy dietary patternPublication . Moreira, Carla; Santos, Rute; Moreira, Pedro; Lobelo, F.; Ruiz, J. R.; Vale, Susana; Santos, Paula Clara; Abreu, Sandra; Mota, JorgeCardiorespiratory fitness (CRF) and diet have been involved as significant factors towards the prevention of cardio-metabolic diseases. This study aimed to assess the impact of the combined associations of CRF and adherence to the Southern European Atlantic Diet (SEADiet) on the clustering of metabolic risk factors in adolescents. A cross-sectional school-based study was conducted on 468 adolescents aged 15-18, from the Azorean Islands, Portugal. We measured fasting glucose, insulin, total cholesterol (TC), HDL-cholesterol, triglycerides, systolic blood pressure, waits circumference and height. HOMA, TC/HDL-C ratio and waist-to-height ratio were calculated. For each of these variables, a Z-score was computed by age and sex. A metabolic risk score (MRS) was constructed by summing the Z scores of all individual risk factors. High risk was considered when the individual had 1SD of this score. CRF was measured with the 20 m-Shuttle-Run- Test. Adherence to SEADiet was assessed with a semi-quantitative food frequency questionnaire. Logistic regression showed that, after adjusting for potential confounders, unfit adolescents with low adherence to SEADiet had the highest odds of having MRS (OR Z 9.4; 95%CI:2.6e33.3) followed by the unfit ones with high adherence to the SEADiet (OR Z 6.6; 95% CI: 1.9e22.5) when compared to those who were fit and had higher adherence to SEADiet.
- Gestational weight gain and relationship with sedentary physical activity in the second trimester of pregnancyPublication . Moreira, Sofia; Santos, Paula Clara; Mesquita, Cristina; Lopes, Sofia; Couto, Miriam; Abreu, Sandra; Mota, JorgePregnancy is phase of big changes for women. Although the growing evidence about the benefits of a physically active lifestyle during pregnancy is still high the number of sedentary pregnant or that interrupt physical exercise during pregnancy. Among other consequences, physical inactivity can be related to weight gain during pregnancy. To evaluate the weight gain in the second trimester of pregnancy and verify if the sedentary physical activity influences this weight gain.
