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.

Obesidade e sintomas de depressão, ansiedade e desesperança em mulheres sedentárias e não sedentárias

The aim of this field study was to verify if there is a relation between obesity and symptoms of depression, anxiety and hopelessness in 40 women aged 30,35 on average (± 8,60), divided into two groups: non-sedentary ones, characterized for doing a physical activity at least three times a week for three weeks in a row and sedentary ones, characterized by not practicing any type of regular physical activity when recruited. The method consisted of: objective evaluations of humor, through Beck Inventories of Anxiety (BAI), Depression (BDI) and Hopelessness (BHS) and Physical Evaluation, including total body mass, height, waist and hip circumferences and skin folds thickness. Calculations of the body mass index (BMI), of the waist/hip index (WHI) and of the percentage of corporal fat (%F) were performed in order to evaluate the presence and level of obesity. Results of the analysis of regression to square minimum supported the initial hypothesis concerning the existence of a relation between obesity and psychic symptoms only in sedentary women (BDI/WHI, p=0,035, BDI/BMI, p=0,009, BDI/%G, p=0,019, BAI/BMI, p=0,009, BAI/%G, p=0,037, BHS/WHI, p=0,025, BHS/BMI, p=0,041), once the relation of dependency could not be confirmed in non-sedentary women BDI/WHI, p=0,750, BDI/BMI, p=0,141, BDI/%G, p=0,064, BAI/WHI, p=0,729, BAI/BMI, p=0,384, BAI/%G, p=0,246, BHS/WHI, p=0,491, BHS/BMI, p=0,986, BHS/%G, p=0,322) and the greater the level of obesity, the greater the level of psychic symptoms in both groups. These observations seem to point out that the practice of physical activities was a factor of minimization of presence and intensity of psychic symptoms in non-sedentary women.

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.
