Abreu, Sandra; Santos, Rute; Moreira, Carla; Santos, Paula Clara; Vale, Susana; Soares-Miranda, Luísa; Mota, Jorge; Moreira, PedroDiet and physical activity are recognized as important factors to prevent abdominal obesity (AO), which is strongly associated with chronic disease (type 2 diabetes, cardiovascular diseases, etc.).
- Atividade física na gravidez e a sua influência nos ganhos ponderaisPublication . Santos, Paula Clara; Couto, Miriam; Soares, Luísa; Abreu, Sandra; Moreira, Carla; Silva, Pedro; Ferreira, Margarida; Santos, Rute; Moreira, Pedro; Montenegro, Nuno; Mota, JorgeComparativamente às grávidas com um peso saudável, as grávidas com excesso de peso ou obesidade têm um aumentado de diabetes gestacional, pré-eclâmpsia, parto induzido, cesariana, prematuridade e macrossomia. Existem várias recomendações quanto à prática de atividade física. Vários estudos revelam que esta prática tem efeitos positivos no que diz respeito ao cumprimento das recomendações do ganho ponderal na gravidez. No entanto, alguns estudos revelaram não haver diferenças no ganho ponderal materno entre grávidas que praticam e as que não praticam exercício.
- Body fatness, cardiorespiratory fitness and inflammatory markers In adolescentsPublication . Moreira, Carla; Abreu, Sandra; Santos, Paula C.; Lopes, LuísThe alarming increase in obesity worldwide and the decrease in cardiorespiratory fitness (CRF) levels among adolescents are of concern in the development of cardiovascular diseases. Therefore, the purpose of this study was to evaluate the association between body fatness, CRF, and inflammatory markers [C-reactive protein (C-RP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), and leptin] in a sample of Portuguese adolescents. We assessed the hypothesis that adolescents with higher body fatness and lower CRF levels will have an increased level of inflammatory markers. A cross-sectional school-based study was conducted on 529 Portuguese adolescents (268 girls) aged 12-18 years (mean age 14.3±1.7). Body fatness (BF) was assessed using the Bioelectric Impedance Analysis. Intravenous blood samples were taken after an overnight fast to determine inflammatory markers (C-RP, IL-6, TNF-α, and leptin). CRF was measured with the 20m-Shuttle-Run-Test from the Fitnessgram battery test as number of laps. Pearson correlation was used for bivariate associations between BF, CRF and inflammatory markers. Linear regression analyses were used to examine the association between BF, CRF and inflammation markers with adjustments for age and sex. Pearson’s correlation analyses, adjusted for age and sex, revealed that BF was positively correlated with leptin (r=0.640, P <0.001) and C-RP (r=0.235, P <0.001), and negatively correlated with CRF (r= -0.473, P <0.001) whereas CRF was inversely correlated leptin (r= -0.420, P <0.001) and C-RP (r= –0.226, P <0.001). Among the inflammatory markers leptin (β= 0.188, p<0.001) and C-RP (β= 0.030, p<0.05) were positively associated with BF whereas leptin (β= -0,160, p<0.001) and C-RP (β= -0.56, p<0.001) were inversely associated with CRF, conversely, TNF-α (β= 0.118, p<0.05) showed a positive association with CRF. No associations were found between BF, CRF and IL-6. Our findings emphasize the importance of increasing CRF levels and decrease body fatness among adolescents in order to prevent metabolic abnormalities predisposed to or associated inflammation and thus contribute to the prevention of cardiovascular diseases later in life.
- 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.
- Evaluation of physical activity programmes for the elderly - exploring the lessons from other sectors and examining the general characteristics of the programmes.Publication . Marques, Ana I.; Soares, Pedro; Soares-Miranda, Luísa; Moreira, Carla; Oliveira-Tavares, António; Santos, Paula Clara; Vale, Susana; Santos, Rute; Carvalho, JoanaIn Portugal, there are several physical activity (PA) programmes for elderly people developed by the local government. The importance of these programmes has been increasing since the evidence has shown that this type of health promotion interventions may reduce the deleterious effects of the ageing process. However, no study has already identified the general characteristics of these programmes nor if they use any scheme to assess the quality of the service provided. A widely-used scheme is the EFQM Excellence Model, which will be in the core of our present work. Thus, the main aims of this preliminary study were 1) to identify the general characteristics of the PA programmes developed by the Portuguese Local Public Administration 2) to determine the extent of implementation of quality initiatives in these programmes. Data were collected by an on-line questionnaire sent to all Continental Municipalities (n = 278). Categorical data were expressed as absolute counts and percentages. Continuous data were expressed as the mean and SD. An open-ended question was analysed using qualitative content analysis with QSR NVivo software. Associations between categorical variables were tested by the use of contingency tables and the calculation of chi-square tests. Significance level was set at p ≤ 0.05. Results showed: i) a total of 125 PA programmes were identified in the 18 districts of the Portugal mainland; ii) the main goal of the majority (95.2%) was the participants' health promotion; iii) different characteristics of the programmes were found according to different regions of the country; iv) certain characteristics of the programmes were associated to the existence of other features; v) only one PA programme developed quality initiatives. In conclusion, although there are many PA programmes for elderly people spread throughout the country, aiming at improving the health of participants, the overwhelming majority does not adopt quality control initiatives. Considering that the quality of a service increases customer satisfaction, the continuous quality improvement of the PA programmes for elderly people should therefore be implemented since they can be useful and critical for elderly satisfaction and adherence.
- Food consumption, physical activity and socio-economic status related to BMI, waist circumference and waist-to-height ratio in adolescentsPublication . Abreu, Sandra; Santos, Rute; Moreira, Carla; Santos, Paula Clara; Mota, Jorge; Moreira, PedroTo examine the association between obesity and food group intakes, physical activity and socio-economic status in adolescents. A cross-sectional study was carried out in 2008. Cole's cut-off points were used to categorize BMI. Abdominal obesity was defined by a waist circumference at or above the 90th percentile, as well as a waist-to-height ratio at or above 0·500. Diet was evaluated using an FFQ, and the food group consumption was categorized using sex-specific tertiles of each food group amount. Physical activity was assessed via a self-report questionnaire. Socio-economic status was assessed referring to parental education and employment status. Data were analysed separately for girls and boys and the associations among food consumption, physical activity, socio-economic status and BMI, waist circumference and waist-to-height ratio were evaluated using logistic regression analysis, adjusting the results for potential confounders. Public schools in the Azorean Archipelago, Portugal. Adolescents (n 1209) aged 15–18 years. After adjustment, in boys, higher intake of ready-to-eat cereals was a negative predictor while vegetables were a positive predictor of overweight/obesity and abdominal obesity. Active boys had lower odds of abdominal obesity compared with inactive boys. Boys whose mother showed a low education level had higher odds of abdominal obesity compared with boys whose mother presented a high education level. Concerning girls, higher intake of sweets and pastries was a negative predictor of overweight/obesity and abdominal obesity. Girls in tertile 2 of milk intake had lower odds of abdominal obesity than those in tertile 1. Girls whose father had no relationship with employment displayed higher odds of abdominal obesity compared with girls whose father had high employment status. We have found that different measures of obesity have distinct associations with food group intakes, physical activity and socio-economic status.

- Gestational Weight Gain and Offspring Bone Mass: Different Associations in Healthy Weight Versus Overweight WomenPublication . Monjardino, Teresa; Henriques, Ana; Moreira, Carla; Rodrigues, Teresa; Adubeiro, Nuno; Nogueira, Luísa; Cooper, Cyrus; Santos, Ana Cristina; Lucas, RaquelWeight management strategies during pregnancy reduce child cardiometabolic risk. However, because maternal weight has an overall positive correlation with offspring bone mass, pregnancy weight management could adversely affect child bone health. We aimed to estimate associations between gestational weight gain (GWG) and bone mineralization in the offspring at 7 years of age, and test early pregnancy body mass index (BMI) as an effect modifier. We analyzed prospective data from 2167 mother-child pairs from the Generation XXI birth cohort who underwent whole-body dual-energy X-ray absorptiometry at 7 years of age. GWG was analyzed as a continuous measure and using the Institute of Medicine categories. In the whole sample and for each early pregnancy BMI category (under/normal weight and overweight/obese), relationships between GWG and offspring bone measures (bone mineral content [BMC], bone areal density [aBMD], size-corrected BMC [scBMC], and height) at 7 years were fitted through local polynomial regression and smoothing splines. The magnitude of associations was estimated through linear regression coefficients (95% CIs), crude and adjusted for maternal age, height, educational level, and child gestational age. In under/normal weight mothers, GWG was associated with slightly increased bone measures at 7 years (per 5 kg of GWG, BMC: 0.07 SD [95% CI, 0.01 to 0.12]; aBMD: 0.10 SD [95% CI, 0.05 to 0.15], scBMC: 0.11SD [95% CI, 0.06 to 0.16], and height: 0.05 SD [95% CI, 0.00 to 0.10]), while in overweight/obese mothers no effect of GWG on bone was observed (BMC: 0.02 SD [95% CI, -0.04 to 0.09]; aBMD: 0.02 SD [95% CI, -0.04 to 0.08], scBMC: 0.01 SD [95% CI, -0.06 to 0.08], and height: 0.02 SD [95% CI, -0.04 to 0.08]). Also, no advantageous effect of gaining weight above the Institute of Medicine recommendations was observed in either early pregnancy BMI group. Our results suggest that adherence to Institute of Medicine recommendations for pregnancy weight gain is unlikely to have a negative repercussion on offspring bone health, particularly in women with excess weight in early pregnancy.
- Impact of compliance with different guidelines on physical activity during pregnancy and perceived barriers to leisure physical activityPublication . Santos, Paula Clara; Abreu, Sandra; Moreira, Carla; Lopes, Diana; Santos, Rute; Alves, Odete; Silva, Pedro; Montenegro, Nuno; Mota, JorgeThe aims of the this prospective study were to analyze physical activity (PA) engagement during the first and second trimesters, considering the different guidelines published on PA, to document the individual characteristics associated with the accomplishment of these guidelines and to examine pregnant women’s perceived barriers to leisure PA, using a socioecological framework. A sample of 133 pregnant women in two stages – at 10–12 weeks’ gestation (T1) and 20– 22 weeks’ gestation (T2) – were evaluated. PA was assessed by accelerometry during the T1 and T2 evaluation stages. Socio-demographic characteristics, lifestyle factors and barriers to leisure PA were assessed via questionnaire. A large proportion of women (ranging from 32% to 96%) did not reach the levels of PA recommended by the guidelines. There were no significant differences between T1 and T2 with regard to compliance with PA recommendations. A decrease in PA levels from T1 to T2 was noted for all recommendations. No associations were found between participants’ characteristics and adherence to the recommendations in T1 and T2. No significant differences were found in barriers to leisure PA between T1 and T2. The most commonly reported barriers to leisure PA were intrapersonal, not health related. Our results indicate that there were no differences between trimesters regarding compliance of PA recommendations, and perceived barriers were similar in both trimesters.
