RESUMO
BACKGROUND/OBJECTIVES: The objectives of this study were to evaluate nutritional status, aptitude and physical activity at the beginning and end of the nutrition education and physical activity intervention program as compared with a control group. METHODS: We conducted a 28-week quasi-experimental study involving 238 students (108 in the intervention group (IG) and 130 in the control group (CG)). The IG participated in curricular and extracurricular activities for nutrition education (50 min once a week) and physical activity (50 min twice a week), and the CG participated only in curricular activities. Nutritional status was determined using body mass index, according to the WHO 2007 curve. The effect of the intervention program was evaluated using a model of generalized estimating equations. RESULTS: Among overweight students, a greater reduction in percentile of BMI was observed in the IG (64.6%) compared with CG (36.4%), P=0.001. Improvement in nutritional status occurred in 26.2% of IG versus 10.4% of CG (P=0.014). The IG showed a significant increase in the amount of moderate or vigorous physical activity (P=0.012), whereas in the control group the increase was not significant (P=0.810). In three physical fitness tests, the IG showed significant improvements in performance (P<0.001), whereas the control group's performance was worse in the final evaluation. CONCLUSIONS: The intervention program had a positive effect on overweight, with significant improvements in nutritional status and physical fitness.

AIM: To evaluate the intestinal absorption in HIV-infected children children 14 months to 14 years and to investigate its relationship to diarrhea, nutritional status, immune dysfunction, classical enteric parasites and Cryptosporidium. METHODS: Intestinal absorption was investigated by measuring serum D-xylose. Fecal samples were investigated for classical pathogens and Cryptosporidium. The sample size was calculated considering a 30% prevalence of altered D-xylose absorption in HIV-infected children with a 5% accuracy. Statistical procedures used were: descriptive measurements, multiple correspondence analysis and logistic regression. RESULTS: D-xylose absorption was altered in only 8 out of 104 (7.7%) and Cryptosporidium was positive in 33 out of 104 (31.73%) HIV-infected children. The multiple correspondence analysis suggested an association between an altered D-xylose test and Cryptosporidium. D-xylose malabsorption was not associated with diarrhea, nutritional status, immune disfunction and classic enteric parasites. CONCLUSIONS: Intestinal malabsorption evaluated through the D-xylose test was an uncommon finding in HIV-infected children. Intestinal dysfunction when present seems to be related to Cryptosporidium, but not to diarrhea, nutritional status, immune disfunction and classic enteric parasites.

The present qualitative and quantitative study had the purposes to verify the meaning of quality of life to nursing professionals using Flanagan's Scale, to identify the quality of life dimensions that are most valued by those professionals and to explore the relations between the quality of life scores obtained by the professionals working at the STD/AIDS unit and at the neonatal ICU. The two groups showed similar results with respect to the meanings and the most valued dimension of quality of life. The total scores presented a positive evaluation of quality of life by the groups, although they showed a difference in the level of quality of life experienced by the two nursing teams.
