Prevalência de sobrepeso e obesidade em escolares de alto nível socioeconômico em Londrina, Paraná, Brasil

Objective: To verify the prevalence of overweight and obesity in 7 to 10 year old schoolchildren of both sexes and high socioeconomic level. Methods: Five hundred and eleven schoolchildren (274 boys and 237 girls) were submitted to anthropometrical measurements of body mass, stature and subscapular and triceps skin-fold thickness. Body mass indexes ≥85th percentile and <95th percentile were used to determine overweight, whereas body mass indexes ≥95th percentile were adopted as indicators of obesity. The socioeconomic level was established based on information obtained from a questionnaire, considering the degree of education of the parents and the familiar consumables. Results: The total prevalence for overweight was 19.7% for the boys and 17.3% for the girls, with no significant differences amongst ages and sexes (p>0.05). On the other hand, the prevalence for obesity in the boys and girls was 17.5% and 9.3%, respectively, with significant differences between the sexes at 9 years (p<0.01) and 10 years (p<0.05) of age, as well as amongst the entire group of ages (p<0.01). Conclusion: The results indicated a high prevalence ratio for overweight (∼19%) and obesity (∼14%), much greater than the average for the 7-10 year old Brazilian population. Therefore, different from that observed in developed countries, a high socioeconomic level seems to negatively affect the prevalence for overweight and obesity, increasing the risk of the precocious development of metabolic dysfunctions.

Área foliar e evapotranspiração de callas cultivadas em substrato em função do nível freático

The objective of this study was to determine the influence of five different water levels on the crop development of Calla. The crop parameters evaluated were leaf area and evapotranspiration. The study was conducted in glass greenhouse with 50% of sunlight reduction. The plants were grown in PVC pots with 150 mm diameter, which were filled with substrate. The plant tubers weighed from 10 g to 12 g. The pots were placed within containers, under water level constant automatically.. The table water levels used were 10, 17, 24, 31 and 38 cm. Nine evaluations during the growth cycle checked the growth development. The evaporation varied from 26.89 to 46.14 L.plant-1 for 38 and 10 cm water levels, respectively and leaf area per plant showed 1011.6 to 2016.3 for the same levels. The substrate water was more available in the treatment 24 cm, with more restrictions in the upper and lower treatments. There was positive correlation between leaf area and evapotranspiration at the final of the culture.

Determinação da distribuição de um nível de turbidito na formação Macaé no campo de Namorado através de uso de atributos sísmicos

This study was developed on the basis of petrophysics characterization, 3D seismic interpretation, and rock-wire-log integration. The results were integrated with amplitude attribute through cross plot (rock attribute x amplitude value). 3D seismic data also allowed inteipreting the top of Lagoa Feia, Macaé, and Carapebus formations, and Outeiro Member. The analyses of the maps of structures and attributes, integrated with wire-log data, suggest that Namorado turbidite level is candidate to be mapped with stratigraphic attributes like AverageTroughAmplitude, RMS velocity and Total AbsoluteAmplitude. Lagoa Feia Formation attribute maps (Dip-Azimuth and TotalEnergy) allows to interpret a low fault density at the carbonate coquina level in the Namorado field. This level is also considered one at the best seismic reflector and an important reservoir of the Campos Basin.

Prevalência de sobrepeso/obesidade e nível econômico de escolares

Objective: To associate the nutritional status of elementary schoolchildren with their gender, age group, and economic status based on a cross-sectional study carried out at public schools in the municipality of Cruzeiro do Oeste, Southern Brazil. Methods: The study was performed in 2010 including 939 schoolchildren aged six to ten years-old. The economical status of the families was classified based on a socioeconomic ranking questionnaire (Brazilian Association of Survey Companies), and the body mass index was calculated. Data were analyzed by descriptive statistics, and differences between independent groups were verified by Mann-Whitney and Kruskal-Wallis tests, while possible associations were verified by the chi-square test, being significant p<0.05. Results: The prevalence of obesity in the sample was 8.0%, and overweight, 16.4%. No association was found between the socioeconomic and nutritional status or between the nutritional status and gender. Conclusions: A high prevalence of overweight and obesity was found in this study, indicating that children of both genders are affected regardless of their economical status and age.

Nível de atividade física, comorbidades e idade de pacientes hipertensos

Physical inactivity is associated with chronic diseases in older adults. There are different domains of physical activity, such as leisure and locomotion. This study investigate the associations between different domains of physical activity, comorbidities and aging in hypertensive adults. Participants included 192 hypertensive respondents classified in groups of active and insufficiently active for leisure-time, locomotion, occupation and total time. They were stratified in age groups. Waist circumference was measured and comorbidities were self-reported. The chi-square test analyzed these associations; a one-way ANOVA compared the age groups (significance at p <0.05). The mean total time and occupational physical activity were lower for groups ages over 60 and 70 years, respectively. Occupational activity was associated with age in the female group, and with cholesterol and diabetes in males, who also had physical activity of locomotion associated with waist circumference. Physical activity of hypertensive patients is associated with comorbidities in different age groups and sex.
