To examine trends in pregnancy and abortion rates observed in Portugal in the last decade. We abstracted all delivery and abortionrelated-admissions to Portuguese public hospitals (2000–2010) using a nationwide inpatient database(corresponding to nearly 96% of all deliveries). We computed age-specific pregnancy and termination of pregnancy rates (all and induced abortion)considering the age groups less than 15, 15–19, 20–34, 35–39 and more than 39 years, using national population estimates as denominator. Joinpoint regression was used to estimate average annual percent change (AAPC) in rates and to identify points in time when significant changes in trend occurred. Youngest teenager pregnancy rates (less than 15 yrs.)decreased significantly from 0.6 to 0.3 per 1000 women (AAPC=-4.9%; p=0.01) with a non-significant decrease in abortion rates (AAPC=-4.1%; p=0.100). Pregnancy and abortion rates per 1000 15–19 year old girls, showed no significant variation up to 2003 (AAPC=-1.8%;p=0.071 for pregnancy and AAPC=2.5%; p=0.449 for abortion). Then, a significant decrease was observed either in pregnancy (from 20.1 to 14.6; AAPC=-5.2%; p<0.001) and in abortion rates (from 2.5 to 1.5; AAPC =-8.2%; p<0.001). Pregnancy rates per 1000 women aged 20–34 decreased from 78.1 to 66.5. It corresponded to a significant decline up to 2004 (AAPC=-3.1%; p=0.020) but a stable course onwards (AAPC=-0.6%; p=0.389). Abortion rates in this age group steadily decreased from 7.7 to 5.5 per 1000 women (AAPC=-3.24%; p<0.001). In contrast...

Introdução: A cada ano, são diagnosticados mais de um milhão de novos casos de câncer de mama em mulheres no mundo. Os países mais desenvolvidos apresentam as maiores incidências, enquanto a mortalidade é maior nos países em desenvolvimento. No Brasil, as incidências mais elevadas se localizam nas regiões Sul e Sudeste. Nos últimos cinco anos, a incidência de câncer de mama aumentou cerca de 30 por cento nos países do ocidente, porém, a partir do ano 2000, observa-se ligeiro decréscimo na mortalidade. A investigação simultânea sobre a incidência e a mortalidade pode fornecer informações sobre a etiologia da doença, e a análise dos efeitos da idade, período e da coorte facilita a compreensão dos mecanismos responsáveis pela variação nas tendências. Objetivos: Analisar as tendências da incidência e da mortalidade por câncer de mama feminino no município de São Paulo, segundo os efeitos da idade, período e coorte. Métodos: Foram analisadas a incidência no período de 1997 a 2005, e a mortalidade no período de 1982 a 2005. Os dados foram obtidos no Registro de Câncer de Base Populacional de São Paulo, no Sistema de Mortalidade do Ministério da Saúde (SIM-MS) e no Instituto Brasileiro Geografia e Estatística (IBGE). Os efeitos da idade...

OBJECTIVE: International data have reported prostate cancer as the most frequent among men, and the third highest in mortality. A rise in incidence has been observed in the course of recent decades, probably influenced by early detection, mainly in asymptomatic men, through regular screening with prostate-specific antigen (PSA) testing. The purpose of this study was to contribute to information on trends in prostate cancer incidence and mortality using population-based data. METHODS: This was an exploratory ecological study of time trends, aiming at describing changes in prostate cancer incidence and mortality in Aracaju, Sergipe, Brazil, from 1996 to 2006. Rates were calculated from data of the Registro de Câncer de Base Populacional de Aracaju. Trends were calculated using the Joinpoint Regression Program. RESULTS: For the study period, 1,490 incident cases and 334 deaths were included. Incident cases were more common after 50 years of age, and deaths after 55 years. Age-standardized incidence rates of 46.6 and 50.0/100,000 were observed in the early years of the series, and then progressively increased, with rates higher than 100.0/100,000 in later years. For mortality, age-standardized rates varied from 21.6 and 16.6/100,000 to 24.1 and 28.9/100...

STUDY OBJECTIVE: To assess the size of mortality differentials in men by social class in Scotland as compared with England and Wales, and to analyse the time trends in these differentials. SUBJECTS: Men from England and Wales and Scotland around each census from 1951 to 1981. METHODS: Poisson regression analysis was used to calculate relative indices of inequality for disease specific and all cause mortality as a measure of mortality differentials between social classes. This measure is not dependent on the size of the social class groups, so it can be used to compare the magnitude of differentials over time periods during which the relative sizes of social class groups change. MAIN RESULTS: While overall death rates were higher in Scotland than in England and Wales around the 1951, 1961, and 1971 censuses the relative indices of inequality indicated smaller mortality differences between social classes in Scotland. Inequality, as indexed by the relative index of inequality, increased over time in both Scotland and England and Wales, but to a greater degree in Scotland, resulting in greater social class mortality differentials for Scotland in 1981 (the relative index of inequality increased from 1.40 to 2.43 for England and Wales...

Registrations from the New Zealand Cancer Registry were used to examine time trends in the incidence of leukaemias among children aged 0-14. There was a statistically significant increase in the incidence of leukaemia among children aged 0-4 during 1953-57 to 1988-90. In this age group, the recorded incidence rate increased from 4.89 per 100,000 person-years in 1953-57 to 7.92 in 1988-90. During 1973-77 to 1988-90 (and probably in earlier years), the increase was due to an increase in acute lymphoblastic leukaemia (ALL). The trends were unlikely to be due to changes in diagnosis or case ascertainment. The childhood leukaemia trends might be related to trends in family size, maternal age, socioeconomic level or exposure to infections. However, there are uncertainties about the importance of these factors or about their trends. The incidence of acute non-lymphoblastic leukaemia (ANLL) decreased between 1968-72 and 1988-90. The time trends highlight the likely importance of environmental factors in the aetiology of childhood leukaemias in New Zealand. The risk of ALL was lower in the Maori than in the non-Maori population (relative risk Maori/non-Maori 0.74). The risk of ANLL was higher among Maori (relative risk 1.84).

Evidence is conflicting as to whether youth obesity prevalence has reached a plateau in the United States overall. Trends vary by state, and experts recommend exploring whether trends in weight-related behaviors are associated with changes in weight status trends. Thus, our objective was to estimate between-state variation in time trends of adolescent body mass index (BMI) percentile and weight-related behaviors from 2001 to 2007. A time series design combined cross-sectional Youth Risk Behavior Survey data from 272,044 adolescents in 29 states from 2001 to 2007. Self-reported height, weight, sports participation, physical education, television viewing, and daily consumption of 100% fruit juice, milk, and fruits and vegetables were collected. Linear mixed models estimated state variance in time trends of behaviors and BMI percentile. Across states, BMI percentile trends were consistent despite differences in behavioral trends. Boys experienced a modest linear increase in BMI percentile (β = 0.18, 95% CI: 0.07, 0.30); girls experienced a non-linear increase, as the rate of increase declined over time from 1.02 units in 2001–2002 (95% CI: 0.68, 1.36) to 0.23 units in 2006–2007 (95% CI: −0.09, 0.56). States in which BMI percentile decreased experienced a greater decrease in TV viewing than states where BMI percentile increased. Otherwise...

There has been an overall decline in the United States incidence of Primary CNS Lymphoma (PCNSL) from 1998 to 2008. This study’s intent was to characterize the cohorts contributing to it. First, calculated the PCNSL incidence rates from nine Surveillance, Epidemiology, and End Results (SEER) registries for time period 1973 to 2008. Second, examined the time trends overall and by age and gender. Third, used 1992–2008 SEER data from the same registries to obtain overall trends for diffuse large B-cell lymphoma (DLBCL). Last, rates were age-adjusted to the 2000 US standard population and reported per 100,000 person-years. Rates continued to increase in women at all ages and men aged 65 and older. In men aged 20–39 and 40–64 years incidence rates peaked in 1995 and then declined dramatically, stabilizing after 1998. The trends in the incidence of PCNSL over this time frame were significantly different from DLBCL for ages 20–39 (P < 0.001) and 40–64 (P < 0.001) years but were not different for the 65 years and older age group (P = 0.99). The overall PCNSL incidence rate declined since 1995 and was driven primarily by the changing incidence in young and middle-aged men. The rate has continued to increase in men aged 65 years and older and in women. The trends in incidence in the younger age groups over this time period did not parallel those observed for DLBCL.

Background: Despite recent advances in surveillance of physical activity, data on time trends of physical activity in low and middle-income countries are lacking. This study describes time trends in physical activity and television viewing between 2006 and 2012 among Brazilian adults. Methods: Data from 371,271 adult participants (18 + years) in the Surveillance System for Risk and Protective Factors for Chronic Illnesses using Telephone Survey (VIGITEL) were analysed. Time trends in leisure-time physical activity (≥ 5 days/wk; ≥ 30 min/day), transportation physical activity (using bicycle or walking for ≥ 30 minutes per day as a means of transportation to/from work) and proportion of participants spending more than three hours per day watching television were analysed. Annual changes according to sex, age and years of schooling were calculated. Results: There was an increase in leisure-time physical activity from 12.8% in 2006 to 14.9% in 2012 (annual increase of 1.9%; p < 0.001). This increase was more marked in younger participants and those with high-school education. Transportation physical activity decreased 12.9% per year (p < 0.001) from 2006 to 2008 and 5.8% per year from 2009 to 2012 (p < 0.001). The annual decline in television viewing time was 5% (p < 0.001) between 2006 and 2009 and 2% (p = 0.16) between 2010 and 2012. Conclusion: National survey data from Brazil indicate that leisure-time physical activity appears to be increasing...

Background: Little is known whether time trends of in‐hospital mortality and costs of care for acute myocardial infarction (AMI) differ by type of AMI (ST‐elevation myocardial infarction [STEMI] vs. non‐ST‐elevation [NSTEMI]) and by the intervention received (percutaneous coronary intervention [PCI], coronary artery bypass grafting [CABG], or no intervention) in the United States. Methods and Results: We conducted a serial cross‐sectional study of all hospitalizations for AMI aged 30 years or older using the Nationwide Inpatient Sample, 2001–2011 (1 456 154 discharges; a weighted estimate of 7 135 592 discharges). Hospitalizations were stratified by type of AMI and intervention, and the time trends of in‐hospital mortality and hospital costs were examined for each combination of the AMI type and intervention, after adjusting for both patient‐ and hospital‐level characteristics. Compared with 2001, adjusted in‐hospital mortality improved significantly for NSTEMI patients in 2011, regardless of the intervention received (PCI odds ratio [OR] 0.68, 95% CI 0.56 to 0.83; CABG OR 0.57, 0.45 to 0.72; without intervention OR 0.61, 0.57 to 0.65). As for STEMI, a decline in adjusted in‐hospital mortality was significant for those who underwent PCI (OR 0.83; 0.73 to 0.94); however...

Smoking prevalence among adolescents in the Middle East remains high while rates of smoking have been declining among adolescents elsewhere. The aims of this research were to (1) describe patterns of cigarette and waterpipe (WP) smoking, (2) identify determinants of WP smoking initiation, and (3) identify determinants of cigarette smoking initiation in a cohort of Jordanian school children. Among this cohort of school children in Irbid, Jordan, (age ≈ 12.6 at baseline) the first aim (N=1,781) described time trends in smoking behavior, age at initiation, and changes in frequency of smoking from 2008-2011 (grades 7 – 10). The second aim (N=1,243) identified determinants of WP initiation among WP-naïve students; and the third aim (N=1,454) identified determinants of cigarette smoking initiation among cigarette naïve participants. Determinants of initiation were assessed with generalized mixed models. All analyses were stratified by gender. Baseline prevalence of current smoking (cigarettes or WP) for boys and girls was 22.9% and 8.7% respectively. Prevalence of ever- and current- any smoking, cigarette smoking, WP smoking, and dual cigarette/WP smoking was higher in boys than girls each year (p These studies reveal intensive smoking patterns at early ages among Jordanian youth in Irbid...

AIM: To-investigate time trends in service provision. DESIGN: Five cross-sectional surveys across a 20-year period. SETTING: Australian private general practice PARTICIPANTS: A random sample of dentists. METHODS: Mailed questionnaires were collected in 1983, 1988, 1993, 1998 and 2003 (response rates 71%-76%). MAIN OUTCOME MEASURES: Services per visit, annual services per dentist; annual services per patient. RESULTS: Total services per visit increased over the study period from 1.78 to 2.37 (Poisson regression; P<0.05). However the annual number of services provided per dentist did not vary significantly, reflecting a trend among dentists to supply fewer patient visits per year. The annual number of services provided per patient increased from 3.47 to 5.50 (OLS regression; P<0.05), reflecting both increased service rates per visit and increased numbers of visits by patients. Dentists provided less restorative, prosthodontic and extraction services per year, but more diagnostic, preventive, endodontic and crown and bridge services. The annual care received per patient also included more diagnostic, preventive, endodontic and crown and bridge services but differed from the dentist pattern through increased rates of restorative services over the study period. CONCLUSIONS: The content of dentist workloads has changed to include less emphasis on removal and replacement of teeth and more effort on diagnosis and prevention aimed at retention of natural dentitions.; D S Brennan...

Background: Aggregate trends have indicated increases in the provision of diagnostic and preventive services but there have been few reports based on their component sub-categories. The aims of this study were to investigate time trends in the provision of sub-categories of diagnostic and preventive services across a 15-year period. Methods: A random sample of Australian dentists was surveyed by mailed questionnaire in 1983-1984, 1988-1989, 1993-1994 and 1998-1999 (response rates 71-75 per cent). Data were weighted to provide representative estimates for the age by sex distribution of private general practitioners in 1983, 1988, 1993 and 1998. Results: Rates per visit were higher, Poisson regression, P<0.05, in 1998-1999 compared to baseline for examinations, radiographs, prophylaxis and topical fluoride. Diagnostic and preventive service rates varied by age of patient: compared to patients aged 65+ years, examinations were higher among children aged <5 years to adults aged 25-44 years, radiographs were lower among children <5 years and 5-11 years but higher among adults aged from 18-24 years to 45-64 years, prophylaxis services were lower among children <5 years but higher among adolescents 12-17 years to adults aged 45-64 years, while topical fluoride was higher among children 5-11 years and adolescents 12-17 years. Conclusions: Examination...

PROBLEM: Young workers are over-represented in injury statistics. In order to develop injury prevention strategies, this study investigated time trends and predictive factors relating to safety skills, confidence, and attitudes. METHOD: Annual surveys were conducted from 2006-2009 among incoming students at the University of Adelaide. The questions addressed safety training, injury experience, and health and safety perceptions. RESULTS: Time trends in training, perceived safety skills, confidence, and attitudes were not significant. In terms of skills and confidence, the most important correlate was safety training outside of high school (odds ratio=1.6), especially when repeated, assessed, or in face to face mode. Feeling strongly about safety issues was best predicted by injury experience (OR=1.7) and gender. DISCUSSION: These results emphasize the value of assessed training, but they are also consistent with published U.S. data, indicating no improvement over time. It is suggested that there be a more integrated approach in safety education, involving schools and workplaces. IMPACT ON INDUSTRY: By developing an understanding of student safety perceptions and experiences, this research aims to target strategies to reduce the excess injury rate for young workers. Workplaces should be more aware of the limitations of school-based safety education and a more integrated and evidence-based approach should be developed...

INTRODUCTION The socio-economic circumstances and health of people with disabilities has been relatively ignored in public health research, policy and practice in Australia and internationally. This is despite emerging evidence that the socio-economic circumstances that people with disabilities live in contributes to their poorer health. Compared to other developed countries, Australians with disabilities are more likely to live in disadvantaged circumstances, despite being an economically prosperous country; it is therefore likely that the socio-economic disadvantage experienced by Australians with disabilities makes a significant contribution to their health. Despite the importance of this issue Australia does not routinely monitor the socio-economic inequalities for people with disabilities. This paper addresses this gap by describing time trends in socio-economic conditions for Australians with and without disabilities according to the severity of the disability and sex. METHODS Cross-sectional analyses of the Australian Bureau of Statistics Survey of Disability, Ageing and Carers were carried out at three time points (1998, 2003 and 2009) to estimate the proportions of women and men (aged between 25 and 64 years) who were living on low incomes...

OBJECTIVE: To investigate time trends in dental service provision. METHODS: A random sample of Australian dentists was surveyed by mailed questionnaires in 1983-1984, 1993-1994, 2003-2004, and 2009-2010 (response rates 67-76%). The service rate per visit was collected from a log of services. RESULTS: The rate of service provision per visit [rate ratio (RR)] increased from 1983-1984 to 2009-2010 for the service areas of diagnostic (RR = 1.8; 1.6-1.9), preventive (RR = 1.9; 1.6-2.1), endodontic (RR = 2.1; 1.7-2.6), and crown and bridge (RR = 2.9; 2.3-3.8), whereas prosthodontic services decreased (RR = 0.7; 0.6-0.9). CONCLUSIONS: The profile of services provided by dentists changed over the study period to include less emphasis on replacement of teeth and more on diagnosis, prevention, and retention of natural dentitions.; David S.

En mi tesis doctoral, se modelizan series temporales con memoria larga y con un componente determinista que potencialmente sufre rupturas. Se consideran contrastes para rupturas y la estimación de los parámetros. Finalmente, se analiza la estimación e ciente de tendencias lineales y su impacto proveniente de la presencia y la longitud de de la pre-muestra. En el primer capítulo, Multiple Breaks in Long Memory Time Series , se propone un enfoque uni cado para la modelización de rupturas en la memoria y la media de una serie temporal. Las series temporales macroeconómicas y financieras a menudo muestran características de memoria larga, como funciones de auto-correlación que decaen hiperbólicamente. Ha habido una larga discusión sobre si tales series temporales se pueden describir por modelos fraccionalmente integrados o si la memoria larga es espuria debido a rupturas en su media. Si bien el número de rupturas es conocido, la fracción de ruptura y los parámetros en los diferentes regímenes se estiman conjuntamente por el método de mínimos cuadrados ordinarios no lineales. El estimador de la fracción de ruptura resulta ser súper-consistente, con una tasa T tanto para rupturas en la memoria como en la media. Por otra parte...

OBJETIVO: Analisar as tendências temporais de duração do aleitamento materno exclusivo e os fatores de proteção. MÉTODOS: Foram analisadas as prevalências de amamentação total e o aleitamento materno exclusivo de lactentes aos quatro meses de idade. Os dados foram obtidos de inquéritos populacionais realizados em 1991, 1997 e 2006, com 935, 2.081 e 1.568 crianças, respectivamente. Os dados foram coletados por entrevista realizada com o responsável pela criança. As prevalências foram analisadas por regressão de Poisson em relação a: condições ambientais, comportamentais e socioeconômicas, variáveis maternas e fatores biológicos da criança. RESULTADOS: A duração mediana do aleitamento total elevou-se de 89 dias (1991) para 106 dias (1997) e, finalmente, 183 dias (2006). A mediana do aleitamento materno exclusivo manteve-se estacionária em torno de 30 dias entre 1997 e 2006. Na análise multivariada, das dez variáveis analisadas, apenas a escolaridade e idade maternas, situação do domicílio e a criança ser do sexo feminino se mantiveram no modelo explicativo final.

Objectives: To determine the cancer incidence in Gipuzkoa (Spain) from 1998 to 2002 and describe time trends since 1986. Methods: The annual incidence of cancer in Gipuzkoa from 1998 to 2002 was estimated as a rate per 100,000 inhabitants. Incidence trends for the period 1986-2002 were studied for all cancers and for the main cancer sites using Poisson regression and Joinpoint regression for prostate tumours. Results: On average, one in 3 men and one in 5 women would probably be diagnosed with cancer at some time during their life (0-74 years). Among men, prostate surpassed lung as the most frequent cancer site. Among women, breast cancer represented approximately 30% of all cases of cancer (excluding non-melanoma skin cancers). There was an annual increase in the incidence of cancer of 1.5% (95% CI, 1.1-1.8) in men and 0.9% (95% CI, 0.5-1.3) in women. The incidence of prostate cancer in men increased over the study period, and especially between 1996 and 1999, with an annual increase of 34.7% (95% CI, 5.9-71.5). The incidence of lung cancer in women presented an annual increase of 5.2% (95% CI, 3.4-7.1). In contrast, the incidence of stomach cancer decreased during the study period.

Objective. This article analyzes the time-trends and causes of infant, neonatal, and postneonatal mortality in Mexico during the 1980’s. Material and methods. Data on infant deaths came from yearly tabulations (1980 to 1990) published by the Mexican government. Time-trends of mortality rates were determined by simple linear regression models. The parallelism test was performed for evaluating similarities in trends in neonatal and postneonatal mortality rates by causes. Results. During the 1980’s, infant mortality rates in Mexico declined from 40.4 to 31.1/1 000 (ß= -0.791). Postneonatal mortality rates showed a strong decrease (ß= -0.892), while neonatal mortality rates were almost stationary (ß= 0.089). Significant rate decreases were observed for Intestinal infections, Pneumonia and influenza and all other causes while Certain perinatal problems, Congenital defects and Nutritional deficiencies increased. No changes were observed in Acute respiratory infections. The neonatal proportional mortality showed an incremental trend accounting for 37.6% in 1980 and ascending to 48.8% in 1990 of the mortality in the first year of life. Conclusions.This analysis indicates that the reduction in infant mortality in Mexico during the 1980’s was due to declining postneonatal mortality while neonatal mortality rates remain almost unchanged.

Objectives: To determine the cancer incidence in Gipuzkoa (Spain) from 1998 to 2002 and describe time trends since 1986. Methods: The annual incidence of cancer in Gipuzkoa from 1998 to 2002 was estimated as a rate per 100,000 inhabitants. Incidence trends for the period 1986-2002 were studied for all cancers and for the main cancer sites using Poisson regression and Joinpoint regression for prostate tumours. Results: On average, one in 3 men and one in 5 women would probably be diagnosed with cancer at some time during their life (0-74 years). Among men, prostate surpassed lung as the most frequent cancer site. Among women, breast cancer represented approximately 30% of all cases of cancer (excluding non-melanoma skin cancers). There was an annual increase in the incidence of cancer of 1.5% (95% CI, 1.1-1.8) in men and 0.9% (95% CI, 0.5-1.3) in women. The incidence of prostate cancer in men increased over the study period, and especially between 1996 and 1999, with an annual increase of 34.7% (95% CI, 5.9-71.5). The incidence of lung cancer in women presented an annual increase of 5.2% (95% CI, 3.4-7.1). In contrast, the incidence of stomach cancer decreased during the study period. Conclusions: Cancer incidence in Gipuzkoa increased during the study period. This increase was particularly marked in lung cancer and skin melanoma...
