Objective: To determine whether an educational programme aimed at discouraging students from drinking sugar-sweetened beverages could prevent excessive weight gain. Design: Forty-seven classes in twenty-two schools were randomised as intervention or control. Subjects: Participants were 1140, 9-12-year-old fourth graders (435 in the intervention group and 608 in the control group). Sugar-sweetened beverages and juice intake were measured through one 24 h recall at baseline and another at the end of the trial. The main outcome was the change in BMI (BMI 5 weight (kg)/height (m 2 )), measured at the beginning and at the end of the school year. Intentionto-treat analysis was performed taking into account the cluster (classes) effect. Results: A statistically significant decrease in the daily consumption of carbonated drinks in the intervention compared to control (mean difference 5 256 ml; 95 % CI 2119, 27 ml) was followed by a non-significant overall reduction in BMI, P 5 0?33. However, among those students overweight at baseline, the intervention group showed greater BMI reduction (20?4 kg/m 2 compared with 20?2 kg/m 2 in the control group (P 5 0?11)), and this difference was statistically significant among girls (P 5 0?009). Fruit juice consumption was slightly increased in the intervention group (P 5 0?08), but not among girls. Conclusion: Decreasing sugar-sweetened beverages intake significantly reduced BMI among overweight children, and mainly among girls. Efforts to reduce energy intake through liquids need to emphasise overall sweetened beverages and addition of sugar on juices.

O objetivo deste trabalho foi examinar os principais fatores de risco associados ao desenvolvimento de osteoporose primária em mulheres na pós-menopausa com osteopenia. Setenta e seis pacientes entre 46 e 85 anos foram selecionadas; 56,6% apresentaram diagnóstico de osteopenia e 43,4%, de osteoporose, de acordo com o critério da Organização Mundial da Saúde. Os fatores de risco foram pesquisados por meio de registro clínico e questionário de freqüência alimentar. O odds ratio foi calculado por meio do aplicativo Statistica. Oitenta e seis por cento das mulheres com osteopenia e 84,8% das com osteoporose apresentaram baixa ingestão de cálcio através de produtos lácteos. O teste "t" para amostras independentes foi aplicado e não inferiu diferença significativa (p= 0,99) entre os dois grupos. No grupo com osteopenia, os fatores de risco assumiram a seguinte forma hierárquica: ausência de terapia de reposição hormonal (2,000), não-exposição ao sol (1,516), consumo de bebidas alcoólicas na juventude (1,346), consumo atual inadequado de cálcio (1,163), ausência de atividade física atual (1,145), história familiar de osteoporose (1,101), ausência de atividade física na juventude (1,006), tabagismo (0,851) e consumo atual de bebidas alcoólicas (0,827). Em conclusão, a ausência de terapia de reposição hormonal foi o fator de risco que indicou maior probabilidade de ocorrência de osteoporose entre as mulheres com osteopenia.

Objectives To identify the nutritional profile of adult and elderly patients with colorectal cancer admitted to a Proctology ward for large elective surgeries. Methods A cross-sectional and retrospective study was performed with 31 patients of both genders, aged 39 to 77 years with colorectal cancer. The nutritional screening parameters used were the percentage of weight loss and Nutrition Risck Screening (NRS 2002). The data (percentage of weight loss and NRS 2002) were collected through a nutritional assessment form completed in the care routine, applied within 72 hours after the patient's hospitalization. Results The study included 13 adults (41.9%) and 18 elderly (58.1%). The evaluation of the percentage of weight loss showed that 7 patients (22.5%) had weight loss greater than 15% in a period of less than or equal to 6 months. In the nutritional risk assessment based on the NRS 2002, we observed that 9 patients (29%) scored 2, while 22 patients (71%) achieved a score equal to or greater than 3. Conclusions The nutritional profile of the evaluated patients showed a considerable prevalence of malnutrition, considering a weight loss of more than 15% in a period of 6 months, which is associated to a decrease in survival in patients with cancer, and is a very relevant data to help in the classification of nutritional status. The classification by the NRS 2002, showed a high prevalence of patients at nutritional or malnourished risk. Variation in the classification of nutritional status using several parameters reinforces the need for them to be used in a complementary way.

Objectives To evaluate the adherence to nutritional monitoring and the evolution of the nutritional parameters of patients submitted to bariatric surgery, in consultations with the nutritionist of the multidisciplinary team of a Federal Public Hospital of Rio de Janeiro. Methods Retrospective study was performed in a cohort of patients submitted to gastric bypass surgery at y-roux from 2013 to 2018. The frequency of consultations and the parameters of the evolution of nutritional status (BMI, % loss total protein, albumin, vitamin 25 OH-D and vitamin B12) in the 1st year of the postoperative period, in the 1˚, 3˚, 6˚ and 12˚ months, totaling 4 consultations in this period. Descriptive statistics were calculated. Results A total of 64 patients with a mean age of 43.6 ± 9.72 years were followed, with 92% (n = 59) females and 8% (n = 5) males. The BMI avarange was 47.86 ± 7.13 kg/m2. Patients' attendance at the 1-year postoperative visits was 95.5% in the first month, 86.4% in the third month, 72.7% in the sixth month, and 57.5% in the twelfth month. Each patient presented an average of 2.9 ± 0.4 visits, corresponding to 72.5% of the total proposed for this nutritional monitoring in the multidisciplinary team. When evaluated individually, a frequency of less than 75% of the scheduled appointments was observed. In relation to the nutritional status parameters: BMI and% of weight loss, it was observed in the 1st month (41.5 ± 5.7 kg/m2 and 10.8% ± 9) and 12˚ months (30, 3 ± 5.4 kg/m2 and 0.3% ± 1.4), respectively. The biochemical parameters, the mean serum levels of total proteins, albumin, ferritin and vitamin B12 were: 1˚ (7.13 g/dl ± 0.92, 4 g/dl ± 0.40, 34.9 ng/ml ± 13, 5; 552.6pg/ml ± 268.0) and 12˚ (7.07 g/dl ± 0.73, 4.0 g/dl ± 0.29, 31.3 ng/ml ± 11.4, 309pg/ml ± 169.6). Conclusions Adherence to treatment and monitoring of the patient's nutritional evolution postoperatively is necessary to reduce possible complications, such as nutrient deficiency or body weight regain.
