A prospective cohort study was conducted in 315 mother-newborn dyads from Valdivia, Chile. A questionnaire was administered to mothers before 48 hours postpartum, and sociodemographic, obstetric, and neonatal data were collected. At 3 months postpartum, a follow-up by telephone interview or home visit was made, determining the proportion of mothers providing exclusive breastfeeding. Multivariate logistic regression was carried out to identify variables significantly associated with exclusive breastfeeding. Follow-up data showed 98.1% were breastfeeding, and exclusive breastfeeding reached 69.5%. Withdrawal of exclusive breastfeeding was positively associated with single marital status (odds ratio, 2.49; 95% confidence interval: 1.48-4.20) and smoking during pregnancy (odds ratio, 2.61; 95% confidence interval: 1.48-4.60), while maternal education greater than 8 years was associated with continuation of exclusive breastfeeding (odds ratio, 0.45; 95% confidence interval: 0.24-0.84). Breastfeeding education strategies addressed to high-risk pregnant women (single with a low education level) must be emphasized in addition to prevention of nonhealthy habits, such as tobacco and alcohol consumption during gestation.

The aim of the study was to assess the trend of the infant mortality rate between 1990-2004 and the neonatal mortality between [2000][2001][2002][2003][2004][2005] in infants born at less than 32 weeks of gestational age or with very low birth-weight. Based on secondary data, infant mortality rate and by its component for Valdivia city were compared with national indicators. Mortality at <32 weeks and <1500g was calculated, establishing causes of death and evaluating its relation with specific interventions, such as the use of surfactant and antenatal corticoids.

We found homes with high [PM]. Residential wood consumption was almost universal, and it is associated with the [PM]. Natural ventilation increased MP, probably due to infiltration from outside.

Introduction: Goalball is a sport specifically created for persons with visual impairments. In spite of all benefits that participating in sport-related activities brings to athletes with visual impairments, there is also the inherent, associated risk of being injured. Competing presenting injuries or illnesses or both not only decrease performance in contests but also increase the risk of acquiring new injuries. There is no information available regarding prior-to-competition injuries or illnesses in athletes with visual impairments. The objective of this research is to determine prevalence of injuries and diseases in athletes prior to a sport-competitive event. Method: A cross-sectional and descriptive study was conducted in 39 athletes (12 women; 41.02 ± 14.96 years old [15.4–71.5]) of Southern Chilean teams participating in the Goalball National Championship. Seven questions from a questionnaire about injuries and illnesses during 4 weeks prior to the competition were analyzed through frequency distribution and measures of key trends. Results: The prevalence of prior injuries was determined as 64.1% ( n = 25), which influenced training in different ways. Sixty percentage of athletes thought these injuries would affect their performance during the championship. Finally, 25.64% ( n = 10) reported having a disease. Conclusions: To our knowledge, this is the first study determining past injuries and illnesses in athletes with visual impairments. This information is important to elaborate preventive strategies and to provide better medical support during competitions. Implications for practitioners: The multidisciplinary teams preparing athletes with visual impairments can use this information to develop preventive strategies to reduce injuries, improve sport performance, and provide better medical support during competitions.
