Neste estudo observacional longitudinal prospectivo, foram avaliados os parâmetros clínicos de 2257 sítios de 16 pacientes não fumantes em manutenção periodontal, através de sondagem computadorizada. Estes pacientes, tratados de periodontite crônica de moderada a severa, receberam manutenção periodontal trimestralmente durante dois anos. Na consulta inicial e aos 3, 6, 9, 12, 18 e 24 meses foram registrados, em seis sítios por dente, os parâmetros clínicos profundidade clínica de sondagem (PCS), retração gengival, nível clínico de inserção (NCI), sangramento e supuração à sondagem e presença de placa, além da mobilidade dentária. A mensuração e registro automatizado destas medidas foram realizados com precisão de 0,2 mm, sob pressão constante de 20 g. Todos os exames foram realizados pelo mesmo examinador, treinado e calibrado. Os sítios monitorados apresentaram, no período avaliado, redução de bolsa e ganho clínico de inserção significativos (p<0,00001). Considerando diferenças maiores do que 1 mm entre o NCI aos 24 meses e no exame inicial, 4,52% dos sítios apresentaram perda de inserção. O modelo multinível de regressão logística mostrou que, quanto menores o NCI e a PCS inicial do sítio...

The present study aimed at analyzing and comparing longitudinally the EMG (electromyographic activity) of the superior orbicularis oris muscle according to the breathing mode. The sample, 38 adolescents with Angle Class II Division 1 malocclusion with predominantly nose (PNB) or mouth (PMB) breathing, was evaluated at two different periods, with a two-year interval between them. For that purpose, a 16-channel electromyography machine was employed, which was properly calibrated in a PC equipped with an analogue-digital converter, with utilization of surface, passive and bipolar electrodes. The RMS data (root mean square) were collected at rest and in 12 movements and normalized according to time and amplitude, by the peak value of EMG, in order to allow comparisons between subjects and between periods. Comparison of the muscle function of PNB and PMB subjects at period 1 (P1), period 2 (P2) and the variation between periods (Δ) did not reveal statistically significant differences between groups (p < 0.05). However, longitudinal evaluation of the muscle function in PNB and PMB subjects demonstrated different evolutions in the percentage of required EMG for accomplishment of the movements investigated. It was possible to conclude that there are differences in the percentage of electric activity of the upper lip with the growth of the subjects according to the breathing mode.

As dificuldades encontradas no ensino e aprendizagem de Matemática têm sido marcadas por constantes buscas de entendimento de uma problemática tão atual e instigativa. O estudo é de caráter longitudinal e monitora o progresso dos alunos desde a 1ª fase do primeiro ciclo do Ensino Fundamental (7 anos) até a 2ª fase (mais ou menos 11 anos), durante quatro anos de escolaridade. Este estudo fez parte do Projeto Internacional de Aquisição Matemática, uma parceria entre a Universidade de Exeter (Inglaterra) e a Universidade Estadual de Londrina (Brasil). Participaram desta pesquisa inicialmente 600 alunos que estudavam em duas escolas estaduais e seis escolas municipais da região de Londrina. A cada ano aplicou-se um teste de Matemática que foi traduzido e validado no Brasil. O teste foi composto por conteúdos da série da qual se trata, repetindo-se algumas questões a cada ano. O conteúdo avaliado referiu-se a números, operações, geometria e medidas e tratamento da informação. Na análise quantitativa utilizou-se da teoria de resposta ao item (TRI) e para a análise qualitativa trabalhou-se com estudo de caso a partir dos resultados da TRI. No último ano da pesquisa, os alunos e professores preencheram um questionário com informações socioeconômicas e pedagógicas relacionadas ao ensino de Matemática. Pretendeu-se com esta pesquisa avaliar o rendimento dos alunos em Matemática ao longo de quatro anos de escolaridade.; The difficulties found within mathematical teaching-learning have been marked by constant searches for an understanding of such a current and inciting issue. This is a Longitudinal study and it has monitored the progress of students from the first phase of the first cycle of the Fundamental Grades ? Elementary School (7 year old students) up to the second phase (11 year old students) for four school years. This study is part of the International Project of Mathematical Attainment...

Objectives: To examine the independent influence of school economic deprivation, social fragmentation, and social cohesion on the likelihood of participating in no physical activity among students. Methods: Data are from a large-scale longitudinal study of schools based in disadvantaged communities in Quebec, Canada. Questionnaires were administered every year between 2002 and 2008 among n = 14,924 students aged 12 to 18 from a sample of 70 schools. Cross-sectional and longitudinal analyses were conducted. Multilevel modeling was utilized to account for the clustering of students within schools. Schools were categorized as being low, moderate or high economic deprivation, social fragmentation and social cohesion. Those who indicated that they do no participate in any physical activity during the week were identified as being physically inactive. Results: In baseline multilevel cross-sectional analyses, adolescents attending schools in the highest (compared to the lowest) levels of socioeconomic deprivation and social fragmentation were more likely to be physically inactive (OR = 1.33, 95% CI = 1.03, 1.72; and OR = 1.24, 95% CI = 0.98, 1.56, respectively). Conversely, students attending schools with the highest cohesion were less likely to be physically inactive (OR = 0.78...

Background: Previous studies testing the association between the built environment and walking behavior have been largely cross-sectional and have yielded mixed results. This study reports on a natural experiment in which changes to the built environment were implemented at a university campus in Hong Kong. Longitudinal data on walking behaviors were collected using surveys, one before and one after changes to the built environment, to test the influence of changes to the built environment on walking behavior. Methods: Built environment data are from a university campus in Hong Kong, and include land use, campus bus services, pedestrian network, and population density data collected from campus maps, the university developmental office, and field surveys. Walking behavior data were collected at baseline in March 2012 (n = 198) and after changes to the built environment from the same cohort of subjects in December 2012 (n = 169) using a walking diary. Geographic information systems (GIS) was used to map walking routes and built environment variables, and compare each subject’s walking behaviors and built environment exposure before and after the changes to the built environment. Walking behavior outcomes were changes in: i) walking distance...

Background: Although the association between lead and cardiovascular disease is well established, potential mechanisms are still poorly understood. Calcium metabolism plays a role in lead toxicity and thus, vitamin D receptor (VDR) polymorphisms have been suggested to modulate the association between lead and health outcomes. We investigated effect modification by VDR genetic polymorphisms in the association between cumulative lead exposure and pulse pressure, a marker of arterial stiffness. Methods: We examined 727 participants (3,100 observations from follow-ups from 1991 to 2011) from the Normative Aging Study (NAS), a longitudinal study of aging. Tibia and patella bone lead levels were measured using K-x-ray fluorescence. Four single nucleotide polymorphisms (SNPs) in the VDR gene, Bsm1, Taq1, Apa1, and Fok1, were genotyped. Linear mixed effects models with random intercepts were implemented to take into account repeated measurements. Results: Adjusting for potential confounders, pulse pressure was 2.5 mmHg (95% CI: 0.4-4.7) and 1.9 mmHg (95% CI: 0.1-3.8) greater per interquartile range (IQR) increase in tibia lead (15 μg/g) and patella lead (20 μg/g), respectively, in those with at least one minor frequency allele in Bsm1 compared with those with major frequency allele homozygotes. The observed interaction effect between bone lead and the Bsm1 genotype persists over time during the follow-up. Similar results were observed in effect modification by Taq1. Conclusions: This study suggests that subjects with the minor frequency alleles of VDR Bsm1 or Taq1 may be more susceptible to cumulative lead exposure-related elevated pulse pressure.

This study identifies developmental processes underlying the relationship between school bullying and physical aggression in emergent adulthood. The data are drawn from the ‘Life at School’ project, a longitudinal study of schooling, socio-emotional functioning, and bullying in a sample of young people living in the Australian Capital Territory. This study consists of three waves of self-report data collected from 88 females and 63 males (N=151) during primary school (Time 1), high school (Time 2) and emerging adulthood (Time 3). The study extends earlier analyses to consider the relative significance of distal functioning and the proximal effects of heavy drinking and work/study roles during the transition to emerging adulthood in shaping pathways from school bullying to adult aggression. … The analyses show that the expression of bullying and adult physical aggression is flexible, open at each stage of development to influence from personal resources (e.g., capacity for adaptive shame management), social resources (e.g., parental education), and changing institutional settings, through for example the cultural and behavioural norms that characterise the university, workplace, and drinking environments and which constrain aggressive behaviour or promote a sense of future orientation. Patterns of adult aggressive behaviours are thus shaped not just by past bullying...

Background. The objective of this study was to determine the pattern of forearm bone loss and its relationship to markers of bone turnover and sex steroids in normal men. This was a longitudinal study over a median interval of 41 months. The study was conducted in Adelaide, Australia. Study participants were 123 healthy male subjects, between the ages of 20 and 83 years. Methods. Fat-corrected forearm bone mineral content (fcBMC), markers of bone formation (alkaline phosphatase, osteocalcin, procollagen type 1 C-terminal extension peptide) and bone resorption (collagen type I cross-linked telopeptide, hydroxyproline/creatinine, pyridinoline/creatinine, and deoxypyridinoline/creatinine), calculated serum bioavailable testosterone, and serum estradiol were measured. Results. The mean time-weighted rate of change in forearm fcBMC was −0.33% ± 0.72 (SD) per year. Bone loss commenced after 30 years of age and increased with age (p < .001), particularly after age 70 years. There was no relationship between the rate of change in fcBMC and either markers of bone turnover or serum sex steroids. Conclusions. In normal men, bone loss increases with age; there does not appear to be any relationship between this loss and either markers of bone turnover or levels of free androgen or estrogen.; F.

Background: Depression is one of the leading contributors to the burden of non-fatal diseases in Australia. Although there is an overall increasing trend in antidepressant use, the relationship between use of antidepressants and depressive symptomatology is not clear, particularly in the older population.. Methods: Data for this study were obtained from the Australian Longitudinal Study of Ageing (ALSA), a cohort of 2087 people aged over 65 years at baseline. Four waves of home interviews were conducted between 1992 and 2004 to collect information on sociodemographic and health status. Depressive symptoms were measured by the Center for Epidemiologic Studies – Depression Scale. Use of antidepressants was based on self-report, with the interviewer able to check packaging details if available. Longitudinal analysis was performed using logistic generalized estimating equations to detect if there was any trend in the use of antidepressants, adjusting for potential confounding factors. Results: The prevalence of depressive symptoms was 15.2% in 1992 and 15.8% in 2004 (p > 0.05). The prevalence of antidepressant users increased from 6.5% to 10.9% (p < 0.01) over this period. Among people with depressive symptoms, less than 20% were taking antidepressants at any wave. Among people without depressive symptoms...

CONTEXT: There is a paucity of longitudinal data on plasma and urinary cortisol levels during pregnancy using modern assays. Furthermore, conflicting data exist as to the effect of the low-dose oral contraceptive pill (OCP) on cortisol. DESIGN, SUBJECTS, AND MEASUREMENTS: We conducted a prospective longitudinal study on morning plasma cortisol (total and free), corticosteroid-binding globulin (CBG), and 24-h urinary free cortisol (UFC) levels in 20 pregnant women during the first, second, and third trimesters and 2–3 months postpartum compared with 12 subjects on low-dose OCP and 15 nonpregnant subjects not taking the OCP (control group). RESULTS: A progressive rise in total plasma cortisol, CBG, and 24-h UFC was demonstrated during pregnancy, peaking during the third trimester (mean 3-fold rise compared with controls). Plasma free cortisol increased 1.6-fold by the third trimester. In the OCP group, total plasma cortisol and CBG were 2.9- and 2.6-fold elevated, respectively, whereas 24-h UFC and plasma free cortisol were not significantly different from controls. Compared with liquid chromatography-mass spectrometry, a commercial immunoassay underestimated mean total plasma cortisol concentrations by 30% during second and third trimesters and in OCP users and overestimated UFC levels by 30–35% during pregnancy. CONCLUSIONS: Our study demonstrated elevations in total plasma cortisol and CBG concentrations during pregnancy and with low-dose OCP use. Pregnancy was also associated with significant increases in plasma free cortisol and UFC...

Despite growing interest and concern about men's mental health during the perinatal period, we still do not know whether men are more vulnerable to mental health problems during this time. The current study is one of the first to use longitudinal, population-based data to investigate whether becoming an expectant and/or new father is associated with increases in psychological distress. We analyzed 10 waves of data collected annually (from 2001 to 2010) from the nationally representative Household, Income, and Labour Dynamics in Australia (HILDA) Survey. Over this time, 349 men were identified as new fathers (first child aged <1 year), and 224 of these men had been identified as "expectant fathers" during the previous wave. A total of 1,658 men remained "never fathers." Psychological distress was measured using the 5-item Mental Health Inventory before the partner's pregnancy, during the partner's pregnancy, and during the first year of fatherhood. Longitudinal mixed models showed no significant increase in psychological distress as a function of expectant or new fatherhood; instead, some improvement in mental health was observed. The finding suggests that expectant and new fathers are not at greater risk of poor mental health. Future epidemiologic research should continue to identify those men who are most (and least) at risk during the perinatal period in order to target resources and assistance most effectively.; This work was supported by a 2011 beyondblue (Australia) national priority-driven research grant (grant LEAC11NPD)...

Although publications in the field of Indigenous health have increased in number in recent decades, their impact remains inadequate (1, 2). This is partially attributable to the continued reliance on descriptive studies (1, 3, 4) and the underrepresentation of urban environments in research. The Longitudinal Study of Indigenous Children (LSIC), administered by the Department of Family and Housing Community Services and Indigenous Affairs (FaHCSIA), addresses both concerns. LSIC is a cohort study of 1,759 Indigenous Australian children from environments ranging from very remote to urban. LSIC‘s retention rate has remained high; however, the dataset withstands a large amount of missing and implausible data. In the first section of this thesis, I evaluated the validity of LSIC anthropometric data. I developed a data cleaning method based on World Health Organization protocols, incorporating knowledge gained from interviews I conducted with LSIC data collectors. These conversations served to depict the process of conducting surveys and to exemplify barriers impeding data collection. They shed light upon the importance of the development of a trusting relationship between participants and the LSIC team, a difficult task within the rigid structure requisite of the conduct of a longitudinal study. Based on these interviews and quantitative analysis of the accuracy of LSIC data...

O objectivo deste estudo é apresentar os resultados de um estudo longitudinal (10 jogos) que explora a existência de correlações estatisticamente significativas entre as quatro dimensões da coesão operacionalizadas pelo Modelo Conceptual de Coesão (Carron, Brawley & Widmeyer, 1985) e diferentes medidas de rendimento desportivo. Os participantes são 23 atletas de uma equipa de futebol profissional (M idade = 22.64; DP idade = 3.89) e os 3 treinadores. Uma versão portuguesa (Martins, Almeida & Viana, no prelo) do Group Environment Questionnaire (Carron, Widmeyer & Brawley, 1985) e um questionário pós-competitivo de avaliação do rendimento, dirigido a treinadores e atletas (Cruz, 1996), foram usados como instrumentos. Os resultados indicam a existência de uma relação entre a Coesão e o Rendimento desportivo em sete dos dez jogos analisados. De forma algo surpreendente e contrariamente ao que seria expectável, verificaram-se correlações positivas e negativas entre a dimensão Integração no Grupo-Social e as diferentes medidas de rendimento. De igual modo, verificaram-se correlações negativas entre as dimensões da coesão com orientação para a tarefa e o rendimento da equipa, contrariando assim todas as evidências. Os resultados obtidos nesta investigação parecem apoiar a concepção de que...

Este estudo teve como objetivo verificar como ocorre e se desenvolve a construção dos conceitos acerca da estrutura da matéria e quais as dificuldades envolvidas nesse processo de aprendizagem. Para esta finalidade foi realizado um estudo longitudinal com um grupo de alunos ao longo do ensino médio. O estudo apresenta a análise do desenvolvimento conceitual desses estudantes, ao manifestarem explicações sobre fenômenos do seu cotidiano, utilizando ideias sobre a estrutura da matéria. Foram empregadas três dimensões de análise: natureza corpuscular da matéria (1ª dimensão), natureza elétrica da matéria (2ª dimensão) e interações intra e interpartículas (3ª dimensão). O estudo foi dividido em duas etapas. Na primeira etapa, participaram 91 alunos de 1ª a 3ª séries de uma escola de Ensino Médio de São Paulo, cujo ensino esteve a cargo de uma mesma professora. A compreensão dos conceitos acerca da estrutura da matéria foi extraída de suas respostas a um questionário contendo questões abertas e fechadas. O conhecimento dos alunos foi avaliado considerando suas respostas em níveis de adequação e compreensão elaborados a partir de uma comparação com respostas de professores especialistas na área de química e de ensino ao mesmo questionário. Verificou-se que as respostas dos alunos se apresentaram entre os níveis de inadequação e parcial adequação com vaga à alguma compreensão na 1ª dimensão de análise para todas as séries. Na 2ª dimensão de análise as respostas foram inadequadas com insuficiente compreensão...

Objective: To identify the cognitive outcome of interviewed participants who did not progress to partake in clinical assessments in a longitudinal aging study. Design: A retrospective study was conducted on participants who were interviewed but who did not complete the clinical assessment (including an extended cognitive assessment) at either Wave 1 or both Wave 1 and Wave 3 of the Australian Longitudinal Study of Ageing. A total of 1947 participants aged 70 and older commenced the study, 246 participants without clinical data at either or both Waves 1 and 3 were identified for the sub-sample followed-up retrospectively. The Informant Questionnaire for Cognitive Decline in the Elderly (IQCODE) was administered to informants and medical records were reviewed. Results: Participants who did not complete the clinical assessment at Wave 3 reported poorer health and had poorer cognitive function at Wave 1 independent of age and gender. Rates of possible dementia or cognitive decline were higher in the group who did not undertake the clinical assessment compared with both those who did the clinical assessment and with population data. Conclusion: Selective non-response to clinical assessment in a longitudinal aging study is associated with higher risk of cognitive decline and probable dementia. Longitudinal aging studies may underestimate rates of dementia and population levels of cognitive decline.

The dedifferentiation hypothesis is examined with respect to age-group differences, ability-group differences, attrition-group differences, and time. Cognitive and sensory data were analyzed from individuals (n = 1,823) who completed a clinical assessment on at least 1 of 3 occasions of measurement in the Australian Longitudinal Study of Ageing. Inconsistent dedifferentiation effects were associated with low ability and early attrition from the study, but age-related dedifferentiation was not found. Longitudinal analyses confirmed the cross-sectional analyses. Even though instances of dedifferentiation were identified between pairs of sensory and cognitive variables, consistent patterns of dedifferentiation were not found. These results do not support the view that shared biological factors become increasingly important for explaining within-individual change in cognitive and sensory function in later life.

 Neste artigo são apresentados resultados de investigação psicossocial longitudinal sobre maternidade de adolescentes pobres de cidades paulistas. O estudo pesquisou condições psicossociais associadas à gravidez na adolescência, em dois momentos: (1) nos primeiros meses após o parto e (2) cerca de quatro anos após o parto. A pesquisa fez uso de entrevistas em profundidade, realizadas nas próprias moradias. As jovens indicavam se perceber como as principais responsáveis pela criação das crianças e não pareciam entender a maternidade de forma negativa. Prejuízos na vida escolar foram aprofundados especialmente por constantes mudanças de moradia. A proximidade de riscos sociais associados à pobreza e aos seus ambientes cotidianos, foi apresentada como integrante de suas vidas. As crianças foram valorizadas, mas referidas como motivo de impedimentos para a disponibilidade para lazer. Os filhos pareciam protegê-las de maior exposição frente a algumas situações de risco (drogas). Palavras-chave: gravidez na adolescência; maternidade de adolescentes pobres; fatores de risco e proteção; estudo longitudinal. ; This article presents the results of a longitudinal psychosocial investigation about adolescent motherhood among poor teenagers in the State of São Paulo.

This is a longitudinal study with 40 infants, 20 infants of adolescent mothers and 20 of adult mothers from Porto Alegre and Butiá, state of Rio Grande do Sul, Brazil. Three evaluations of motor and cognitive development were performed using the Alberta Motor Infant Scale (AIMS) and the Bayley Scale Infant Development II. Significant difference in the supine position of AIMS was observed between groups in the third evaluation. Infants of adolescent mothers showed lower scores than those of adult mothers. The motor scores of each position and total AIMS score showed significant difference during overall time and in each group. The Bayley-II mental score also showed significant difference during overall time and in each group. There was a positive, strong and significant association between AIMS and Bayley scores in all three evaluation stages as in the group of infants of adolescent and adult mothers. It was concluded that infants of adolescent mothers showed worse results in the supine position during the third evaluation than those of adult mothers.

A longitudinal study of animal and human rabies covering 18 years from 1989 to 2006 was retrospectively conducted in order to highlight the epidemiological features and trends of the disease in Botswana. Over the 18-year period, a total of 4 306 brain specimens collected from various species of animals including human beings with clinical signs consistent with rabies were submitted to the National Veterinary Laboratory in Gaborone for confirmatory diagnosis. Of the samples submitted, 2 419 cases were found to be positive for lyssavirus antigen; this presents an overall prevalence rate of 56.18 ± 1.48 %. About 85.7 % (2 074/2 419) of the cases were from domestic animals, 14.2 % (343/2 419) cases were from wild animals and two cases (0.1 %) were from human beings. During the first half of the study (1989-1997) the prevalence rate of the disease was estimated at 62.79 ± 1.85 % (1 645/2 620 positive) whereas during the second half (1998-2006) it was estimated at 45.91 ± 2.38 % (774/1 686 positive) and the difference between the two estimates was statistically, highly significant (Δ % = 16.88, SE (95), diff % = 3.015, SD = 5.599; P< 0.001). Ruminant rabies accounted for 79.99 % (50.92 % bovine, 28.40 % caprine and 0.67 % ovine) whereas canine (domestic dog) and feline (domestic cat) accounted for 16.01 and 0.87 %...
