In order to describe adequacy of weight gain during pregnancy and its association with pre-pregnancy nutritional status and other factors, a cohort study of pregnant women enrolled at 16-36 weeks of gestation and followed up until delivery was carried out in prenatal care in primary care services in Rio Grande do Sul State, Brazil. Maternal weight was recorded at each prenatal care visit. Weight gain was classified as "adequate," "insufficient" or "excessive" (Institute of Medicine). Poisson regression was used to measure the associations. The sample was comprised of 667 women, and insufficient and excessive weight gain incidences were 25.8% and 44.8%, respectively. Overweight and obese before pregnancy had a significant increased risk of excessive weight gain in pregnancy (RR: 1.75; 95%CI: 1.48-2.07, RR: 1.55; 95%CI: 1.23-1.96, respectively). Women with fewer than six prenatal visits had a 52% increased risk for weight gain below recommended values. Although insufficient weight gain may still be a public health problem, excessive gain is becoming a concern that needs immediate attention in prenatal care.

Background: Studies on the natural history of rare, chronic diseases like spinocerebellar ataxia 3 (SCA3) are hard to be done, since patients enter the study with variable disease durations and are followed up at irregular intervals., Aims: Our purpose was to use all the available data to describe the progression of gait ataxia in a long-term cohort of patients with SCA3 through a markovian method., Materials and Methods: SCA3 patients were recruited between 1998 and 2005 and were invited to annual neurological follow-ups until 2007. Gait ataxia was described through a mean score graph and a mean trajectory graph., Results: We followed up 105 patients; at baseline, the mean age and disease duration were, 40.5 (SD = 12.6) and 7.7 (SD = 5.8) years, respectively. The mean time to reach stages 1, 2, 3 and 4 of gait ataxia were 3, 5.4, 10.8 and 19.4 years of disease duration. The mean score graph was unsmooth, showing several unlikely ups and downs. The mean trajectory graph produced a continuous curve., Conclusion: The markovian method described the natural history of gait ataxia without any a posteriori adjustment of data and allowed statistical comparisons between subgroups. This method will be useful in future clinical trials in this and in other chronic degenerative diseases., (2010 S. Karger AG, Basel.)

Objective: To examine the prevalence of inappropriate eating behaviors and associated factors among pregnant women in primary care., Method: The Eating Disorder Examination Questionnaire was used to assess eating disorders and the Primary Care Evaluation of Mental Disorders was used to examine anxiety and depressive symptoms. Body mass index (BMI) and pregestational weight were also assessed., Results: Prevalence of binge eating during pregnancy was 17.3% [95% confidence interval (CI) 14.5-20.0], followed by excessive shape (5.6%; 95% CI 4-8) and weight concerns (5.5%; 95% CI 4-8). Binge eating during pregnancy was significantly associated with binge eating before pregnancy [prevalence ratio (PR) = 3.1; 95% CI 2.2-4.3], current anxiety symptoms (PR = 1.8; 95% CI 1.3-2.4), and prepregnancy BMI < 19.8 kg/m(2) (PR = 1.6; 95% CI 1.1-2.5). The prevalence of eating disorders was 0.6% (95% CI 0.01-1.11)., Discussion: Eating disorder symptoms should be routinely assessed and treated during prenatal care, along with other comorbid psychiatric symptoms such as anxiety.

Objective: To investigate whether abnormal eating behaviors in young women could predict eating disorders after 4 years., Method: 56 women were identified as presenting abnormal eating behaviors in a cross-sectional study (Eating Attitudes Test-26 and Edinburgh Bulimic Investigation Test). They were matched for age and neighborhood to two controls (n = 112). Four years later, they were re-assessed with the two screening questionnaires plus the Composite International Diagnostic Interview (CIDI 2.1)., Results: Women with abnormal eating behaviors at baseline showed a high probability of presenting abnormal eating behaviors but it was not associated with eating disorders 4 years later. They were also at higher risk for obsessive-compulsive disorder, post-traumatic stress disorder, and specific phobia., Discussion: Abnormal eating behaviors were related to the maintenance of the disturbed behavior over the years, and were associated with increased probability for psychiatric diagnoses.

Objective: Depressive disorders represent a major public health problem due to their high prevalence and psychosocial impact. Depressed patients are assiduous users of primary care services, although their depression is very often misdiagnosed. The objective of the study is to evaluate the association between depressive symptoms and social functioning in individuals that seek primary care services in a Brazilian capital., Methods: The study included 2,201 primary care users in the city of Porto Alegre, Brazil. The participants' physical and emotional health was assessed through an interview using a questionnaire including 2 general questions from the World Health Organization's Quality of Life instrument (WHOQOL-brief); other questions from the Medical Outcomes Study Short-Form 12 (SF-12), MHI 5 (MHI-5), Centers for Epidemiologic Studies-Depression (CES-D), and additional questions about work loss days and health care utilization., Results: Of all individuals, 79.5% were women aged on average 40 years. The intensity of depressive symptoms (measured by CES-D) was 20.2 for women and 16.2 for men. All parameters studied had an inverse relationship with the intensity of depressive symptoms., Conclusions: This study reinforce the findings that depressive symptoms have a strong association with poor social functioning and quality of life and a higher utilization of health resources in primary care patients.
