Excessive crying at 3 months of age and behavioural problems at 4 years age: a prospective cohort study.

Background: Excessive crying in early infancy has been associated with behavioural problems among preschool children from high income countries but studies in low income and middle income countries are scarce.

Methods: The 2004 Pelotas Birth Cohort is a population-based study planned to enrol all live births occurring in Pelotas that year and comprises 4231 children who so far have been followed up at 3, 12, 24, 48 and 72 months of age. Several familial, maternal and child characteristics were gathered in every follow-up.

[Self-reported health status in adolescents, adults and the elderly].

[Ambulatory care utilization in the past 15 years: comparison between two population-based studies].

Profound changes in the Brazilian health system have occurred in the past few decades. Data from two cross-sectional population-based studies carried out in 1992 (n = 1,657) and 2007 (n = 2,706), among individuals from 20-69 years, were compared aiming to describe changes in Pelotas, Brazil. Prevalence of consultations in the past twelve and three months were calculated and stratified by gender.

[Non-communicable chronic diseases: performance of medical care in Primary Health Care in southern Brazil].

A cross-sectional study was performed to assess knowledge and performance on the prevention of risk factors for chronic non-communicable diseases (CNCD) in adults, among primary care physicians in the urban health system in Pelotas, Rio Grande do Sul State, Brazil. The study included observation of 422 consultations by 61 physicians. 58.

Risk factors for chronic non-communicable diseases and the CARMEN Initiative: a population-based study in the South of Brazil.

The CARMEN Initiative is a strategy of the Pan American Health Organization and the World Health Organization that proposes population-based interventions to reduce risk factors for chronic non-communicable diseases (CNCD) by approaching them simultaneously. The present study aims to provide a baseline for further interventions by the CARMEN Initiative based on a cross-sectional population-based study of 3,100 adults (>20 years old) in Pelotas, a city in the South of Brazil. Prevalence of smoking, physical inactivity, diabetes mellitus, hypertension, and excess weight were studied and presented separately and aggregated in various combinations.

[Individual factors associated with medical consultation by adults].

Subjects were interviewed to obtain socioeconomic, demographic, and health-related data, as well as information on the number of medical appointments in the past three months.
