- Adiposity indicators and cardiovascular risk factors in Azorean adolescentsPublication . Moreira, C.; Santos, R.; Vale, S.; Santos, Paula Clara; Marques, A.; Abreu, S.; Soares-Miranda, L.; Mota, J.This study was conducted to evaluate the association of adiposity indicators (body mass index, waist circumference and waist-to-height ratio) with cardiovascular risk factors in lean andobese Azorean adolescents.
- Association between calcium intake and body fat among pre-school Portuguese childrenPublication . Abreu, S.; Vale, S.; Pereira, M.; Santos, R.; Moreira, C.; Santos, P.; Soares-Miranda, L.; Mota, J.; Moreira, P.Obesity is the condition in which abnormally large body fat mass accumulates and causes a broad range of health problems. Some studies with children have reported an inverse asso ciation between dietary calcium intake and adiposity.
- Association between dairy product intake and abdominal obesity in Azorean adolescentsPublication . Abreu, S.; Santos, R.; Moreira, C.; Vale, Susana; Santos, Paula Clara; Soares-Miranda, L.; Marques, A. I.; Mota, J.; Moreira, P.Some studies have reported an inverse association between dairy product (DP) consumption and weight or fat mass loss. The objective of our study was to assess the association between DP intake and abdominal obesity (AO) among Azorean adolescents. This study was a cross-sectional analysis. A total of 903 adolescents (370 boys) aged 15--16 years was evaluated. Anthropometric measurements were collected (weight, height and waist circumference (WC)) and McCarthy’s cut-points were used to categorize WC. AO was defined when WC was X90th percentile. Adolescent food intake was assessed using a self-administered semiquantitative food frequency questionnaire and DP intake was categorized in o2 and X2 servings/day. Data were analyzed separately for girls and boys, and logistical regression was used to estimate the association between DPs and AO adjusting for potential confounders. The prevalence of AO was 54.9% (boys: 32.1% and girls: 70.7%, Po0.001). For boys and girls, DP consumption was 2.3±1.9 and 2.1±1.6 servings/day (P¼0.185), respectively. In both genders, the proportion of adolescents with WC o90th percentile was higher among individuals who reported a dairy intake of X2 servings/day compared with those with an intake o2 servings/day (boys: 71% vs 65% and girls: 36% vs 24%, Po0.05). After adjustments for confounders, two or more DP servings per day were a negative predictor of AO (odds ratio, 0.217; 95% confidence interval, 0.075 -- 0.633) only in boys. We found a protective association between DP intake and AO only in boys.
- Association between dietary calcium intake and blood pressure among portuguese childrenPublication . Abreu, S.; Moreira, P.; Mota, J.; Santos, Rubim; Moreira, C.; Santos, Paula Clara; Soares-Miranda, L.; Vale, S.Higher blood pressure (BP) in childhood is associated with cardiovascular risk. It has been described that dietary calcium intake may affect BP regulation. The objective of this study was to analyze the association between dietary calcium intake and BP in children.
- Associations between neck circumference and adipocytokines among adolescentsPublication . Moreira, C.; Mota, J.; Abreu, S.; Lopes, L.; Agostinis, C.; Oliveira, A.; Oliveira-Santos, J.; Santos, P. C.; Santos, R.Neck circumference (NC) was recently introduced as a predictor of cardiovascular disease (CVD) risk factor. Adipocytokines may have a key role in the development of CVD. Aims: The purpose of this study was to examine the associations between NC and adipocytokines, such as adiponectin and leptin in Portuguese adolescents.
- Caracterização cinemática e dinamométrica da marcha de indivíduos obesosPublication . Sousa, Helena; Peduzzi, M.; Abreu, S.; Santos, Rubim; Vilas-Boas, JPA obesidade é considerada uma das epidemias do século XXI.A marcha é a actividade física mais recomendada para a perda e manutenção de peso. No entanto, esta actividade pode tornar-se agressiva sob o ponto de vista biomecânico.
- Impact of a school-based intervention to promote fruit intake: a cluster randomized controlled trialPublication . Rosário, R.; Araújo, A.; Padrão, P.; Lopes, O.; Moreira, A.; Abreu, S.; Vale, S.; Pereira, B.; Moreira, P.Objective: There is evidence that fruit consumption among school children is below the recommended levels. This study aims to examine the effects of a dietary education intervention program me, held by teachers previously trained in nutrition, on the consumption of fruit as a dessert at lunch and dinner, among children 6-12 years old. Study design: This is a randomized trial with the schools as the unit of randomisation. Methods: A total of 464 children (239 female, 6-12years) from seven elementary schools participated in this cluster randomized controlled trial. Three schools were allocated to the intervention and four to the control group. For the intervention schools, we delivered professional development training to school teachers (12 sessions of 3 h each). The training provided information about nutrition, healthy eating, the importance of drinking water and healthy cooking activities. After each session, teachers were encouraged to develop classroom activities focused on the learned topics. Sociodemographic was assessed at baseline and anthropometric, dietary intake and physical activity assessments were performed at baseline and at the end of the intervention. Dietary intake was evaluated by a 24- h dietary recall and fruit consumption as a dessert was gathered at lunch and dinner. Results: Intervened children reported a significant higher intake in the consumption of fruit compared to the controlled children at lunch (P = 0.001) and at dinner (P = 0.012), after adjusting for confounders. Conclusions: Our study provides further support for the success of intervention programmes aimed at improving the consumption of fruit as a dessert in children.
- Insulin resistance and its relation to adiposity, cardiorespiratory fitness and dietary intake among Azorean adolescentsPublication . Moreira, C.; Rute, Santos; Vale, S.; Santos, P. C.; Marques, A. I.; Soares-Miranda, L.; Abreu, S.; Mota, J.Insulin resistance is an important compo nent in the development of metabolic syndrome and lifestyle-related diseases. The aim of the present study is to investigate the relationship between insulin resistance (IR), adiposity, cardiorespiratory fitness (CRF) and dietary intake among Azorean adolescents.
- Physical activity during pregnancy and its effects on fetal parameters in the second trimesterPublication . Santos, P. C.; Alves, V .; Couto, M.; Ferreira, M.; Alves A, O.; Mesquita, C.; Lopes, S.; Abreu, S.; Mota, J.The physical activity (PA) during pregnancy still remains controversial due to the risk and protective effects on the fetal parameters (cephalic perimeter, abdominal perimeter, femur length and fetal weight). The American College of Sports Medicine (ACSM) recommends that pregnant women do, at least, 150 weekly minutes of moderate PA during a week (WK). This study aimed to (1) verify the relation between the accomplishment of ACSM guidelines PA and the maternal individual characteristics; (2) verify the relation between accomplishment of these guidelines and the fetal parameters in the second trimester. Prospective study was conducted at Hospital S. João, with a sample of 137 pregnant women. Socio-demographic characteristics and lifestyle factors were assessed via questionnaire. PA was assessed by accelerometry (used for 7 consecutive days) in the second trimester (20–22 weeks). The fetal parameters were assessed by ultrasound between the 20th and 22nd gestational week, always by the same medical. No relation was found between the participants’ individual characteristics and the accomplishment of the ACSM’s recommendations, with p-value for all the variables being >0.05. There is no difference between the fetal parameters in the second trimester of the women who follow the recommendations (p>0.05). The pregnant women’s individual characteristics were not related with the accomplishment of the ACSM’s recommendations. Any relation between the recommendations accomplishment and the fetal parameters in the second trimester was not found and no negative influence was found in the same parameters.
