High intake of fruits and vegetables predicts weight loss in Brazilian overweight adults

To determine whether changes in dietary intakes predict weight loss, we studied 80 overweight adults who attended a nutritional counseling program during 6 months of follow-up at a primary health care center in Brazil. Habitual diet was assessed using a validated food frequency questionnaire at baseline and after 6 months. The mean age (+/-SD) of the participants was 46.5 +/- 9.5 years, and their mean body mass index was 29 +/- 3 kg/m(2) at baseline. After 6 months, the differences in body weight and fruit/vegetable intake were -1.4 +/- 3 kg and 109 +/- 320 g daily, respectively. Using multiple linear regression models adjusted for age, sex, changes in walking time, and total energy intake, the increased intake of dietary fiber from fruits/vegetables was associated with a greater weight loss (beta 1 [95% confidence interval (CI)] = -0.180 [-0.269, -0.0911) after 6 months of follow-up. Similar results were observed for increased intake of vegetables (beta 1 [95% CI] = -0.00497 [-0.008, -0.0021) and fruits (beta 1 [95% CI] = -0.00290 [-0.005, -0.001]) as predictors of weight loss. The increase of 100 g/d of vegetables and fruits represented a body weight loss of 500 and 300 g after 6 months, respectively (P <.05). Our findings support the relevance of increased intakes of fruits and vegetables that may help avoid weight gain in overweight adults. (C) 2008 Elsevier Inc. All rights reserved.

Association between particulate matter from biomass burning and respiratory diseases in the southern region of the Brazilian Amazon

Objective. To investigate the short-term effects of exposure to particulate matter from biomass burning in the Amazon on the daily demand for outpatient care due to respiratory diseases in children and the elderly. Methods. Epidemiologic study with ecologic time series design. Daily consultation records were obtained from the 14 primary health care clinics in the municipality of Alta Floresta, state of Mato Grosso, in the southern region of the Brazilian Amazon, between January 2004 and December 2005. Information on the daily levels of fine particulate matter was made available by the Brazilian National Institute for Spatial Research. To control for confounding factors ( situations in which a non-causal association between exposure and disease is observed due to a third variable), variables related to time trends, seasonality, temperature, relative humidity, rainfall, and calendar effects ( such as occurrence of holidays and weekends) were included in the model. Poisson regression with generalized additive models was used. Results. A 10 mu g/m(3) increase in the level of exposure to particulate matter was associated with increases of 2.9% and 2.6% in outpatient consultations due to respiratory diseases in children on the 6th and 7th days following exposure. Significant associations were not observed for elderly individuals. Conclusions. The results suggest that the levels of particulate matter from biomass burning in the Amazon are associated with adverse effects on the respiratory health of children.

Kvinnors behov av stöd vid bröstcancer : - En litteraturöversikt

Bakgrund Bröstcancer är den vanligaste typen av cancer hos kvinnor över hela världen. De som drabbas av bröstcancer har olika förutsättningar att hantera sin situation. Många av kvinnorna upplever en emotionell kris i samband med diagnosen och med hjälp av stöd från sjukvården kan patienten finna mening i sin situation. Syfte Syftet är att sammanställa aktuell forskning om bröstcancerdrabbade kvinnors effekter av stöd under diagnosperioden. Metod En litteraturöversikt som sammanställer aktuell forskning inom det valda omvårdnadsområdet. Resultat I resultatet framkom att kvinnorna behöver ett stöd i form av kommunikation, information samt ett emotionellt stöd från vårdpersonal. Stödet ska utformas efter patientens unika situation och när sjukvården är tillgänglig för patienterna minskas deras stress. Patienterna upplevde stöd under diagnosperioden då sjuksköterskan erhöll god förmåga att bemöta och kommunicera på ett adekvat sätt. Slutsats Studien visar att det krävs en god relation mellan bröstcancer drabbade kvinnor och vårdaren för att kvinnorna ska känna stöd.
