Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Background and aims: Lifestyle variables have a key role in the development of abdominal obesity (AO). The objective of this study was to identify lifestyle factors and socioeconomic variables associated with AO in adolescents. Methods and results: This study carried out a school-based survey in the Brazilian city of Maringá in Paraná. The representative sample was of 991 adolescents (54.5% girls) from both public and private high schools selected through multi-stage random sampling. AO was classified according to waist circumference value. The independent variables studied were: gender, age, socioeconomic level, parental and household characteristics, smoking, alcohol use, physical inactivity, sedentary behaviour and nutrition-related habits. Poisson regression was used with robust variance adjustment to analyse the associations. The analysis was stratified by sexes. The prevalence of AO was 32.7% (girls = 36.3%, boys = 28.4%). In girls, excessive intake of fried foods was inversely associated with AO and excessive consumption of soda was positively associated. In boys, the results demonstrated a negative association with excessive consumption of sweets and soda. Conclusion: It is concluded that the prevalence of AO among adolescents was higher in both sexes. AO is associated with different eating habits in females and males and these relationships are mediated by familial contexts. © Informa UK...

Objectives. To determine the natural history of infant spilling (regurgitation/vomiting) during the first 2 years of life and to determine the relationship between infant spilling and gastroesophageal reflux (GER) symptoms at 9 years of age. Methods. A prospective birth cohort was followed with daily symptom diaries during the first 2 years of life and reviewed at 9 years of age (range: 8–11 years). The prevalence of infant spilling during the first 2 years of life, the prevalence of GER symptoms between 8 and 11 years of age (mean age: 9.7 years), relative risk of infant spilling predisposing to GER symptoms at 9 years of age, and prevalence of maternal GER symptoms and relationship with infant spilling and GER at 9 years of age were measured. Results. A total of 693 children who represented 83% of an original sample of 836 children and were followed for 2 years from birth with daily symptom diaries were contacted at 9 (8–11) years of age. Spilling of most feeds each day was common in infancy and reached a peak prevalence of 41% between 3 and 4 months of age and thereafter declined to < 5% between 13 and 14 months of age. Infants with spilling on 90 days or more during the first 2 years of life (classified as frequent spilling) were more likely to have GER symptoms at 9 years of age. Children with frequent infant spilling...

Aims: To determine the prevalence of and risk factors for cataracts in a rural region of central Myanmar. Methods: A cross-sectional, population-based survey of inhabitants >=40 years of age from villages of central Myanmar; 2076 participated, and 2044 (82.3%) had an examinable lens in at least one eye. Data recording included smoking history, occupation, education level, betel-nut chewing, height and weight, and dilated lens assessment using Lens Opacities Classification System III grading: nuclear (>=4), cortical (>=2) and posterior subcapsular (>=2) cataracts. Aphakic and pseudophakic eyes were included as operated cataracts for statistical analysis. Results: The prevalence of any cataract including operated eyes was 40.39% (95% CI 37.30 to 43.48%): 27.35% nuclear, 20.91% cortical and 11.34% posterior subcapsular cataracts. No significant association was found between cataract and betel-nut use, gender, smoking or outdoor occupation. The likelihood of all cataract types increased with age (multivariate analysis including operated eyes: OR 1.154, CI 1.13 to 1.18, p<0.001). Low level of education and low body mass index were associated with nuclear cataracts. Large village size was associated with increased risk for nuclear cataract (OR 3.23...

Background: It has been suggested that gender and age could be factors that influence the likelihood of success following antireflux surgery, and our anecdotal impression has been that the outcome following Nissen fundoplication in older women is often disappointing. If correct, characterization of the extent of any differences in outcome might help patient selection and, hence, surgical outcomes. Therefore, in this study we investigated the impact of gender and age on longer-term clinical outcomes following laparoscopic fundoplication. Methods: Perioperative and follow-up data from patients undergoing laparoscopic fundoplication in our departments have been collected prospectively and stored in a database. From the database, patients who had undergone either an anterior 180° partial or 360° total laparoscopic fundoplication for gastroesophageal reflux and completed 5 years clinical follow-up were identified. Patients were classified according to gender and age, and outcome data were analyzed to determine differences. Analog scales of 0–10 were used to determine symptoms of heartburn and dysphagia and overall satisfaction. Results: Seven hundred three patients were studied (58% males). Females were less satisfied with the outcome (score = 7.8 ± 2.8 vs. 8.4 ± 2.5...

Aims To determine the prevalence, associations and risk factors for age-related macular degeneration (ARMD) in central Sri Lanka. Methods The study was a population-based, cross-sectional survey of residents aged ≥40 years in rural Sri Lanka. ARMD was assessed on dilated fundoscopy using the International Age-Related Maculopathy Epidemiology Study Group classification system. Results Of the 1721 subjects identified, 1375 participated (79.9%). Of the participants, 1013 were aged ≥50 years (73.6%). The prevalence of any ARMD (adjusted for study design) was 4.72 (95% CI 2.22 to 7.20)% with 3.82 (95% CI 1.60 to 6.04)% early ARMD and 1.70 (95% CI 0.14 to 3.27)% late ARMD. Age (p<0.001) and Sinhalese ethnicity (p = 0.016) were significantly associated with ARMD. Men had a tendency toward a higher prevalence of ARMD than women, although this was not statistically significant (p = 0.081). Ocular risk factors such as cortical cataract (p = 0.024) and pseudophakia (p = 0.003) were associated with ARMD on the univariate but not multivariate analyses. Illiteracy and the identification of social supports were significantly associated with ARMD on univariate analyses. However, only social support was statistically significant after multivariate analysis (p = 0.024). Conclusions Although the prevalence of ARMD is slightly lower in Sri Lanka than surrounding regions...

Background: Although often providing more reliable and informative findings relative to other study designs, longitudinal investigations of prevalence and predictors of suicidal behaviour remain uncommon. This paper compares 12-month prevalence rates for suicidal ideation and suicide attempt at baseline and follow-up; identifies new cases and remissions; and assesses the capacity of baseline data to predict serious suicidality at follow-up, focusing on age and gender differences. Methods: 6,666 participants aged 20-29, 40-49 and 60-69 years were drawn from the first (1999-2001) and second (2003-2006) waves of a general population survey. Analyses involved multivariate logistic regression. Results: At follow-up, prevalence of suicidal ideation and suicide attempt had decreased (8.2%-6.1%, and 0.8%-0.5%, respectively). However, over one quarter of those reporting serious suicidality at baseline still experienced it four years later. Females aged 20-29 never married or diagnosed with a physical illness at follow-up were at greater risk of serious suicidality (OR = 4.17, 95% CI = 3.11-5.23; OR = 3.18, 95% CI = 2.09-4.26, respectively). Males aged 40-49 not in the labour force had increased odds of serious suicidality (OR = 4.08, 95% CI = 1.6-6.48) compared to their equivalently-aged and employed counterparts. Depressed/anxious females aged 60-69 were nearly 30% more likely to be seriously suicidal. Conclusions: There are age and gender differentials in the risk factors for suicidality. Life-circumstances contribute substantially to the onset of serious suicidality...

Background: The Manchester Foot Pain and Disability Index (MFPDI) has been used to determine the prevalence of disabling foot pain in several studies, however there is some debate as to which case definition is most appropriate. The objective of this study was to explore age and gender differences in the proportion of people with disabling foot pain using three different case definitions of the MFPDI and for each individual MFPDI item. Methods: A random sample of 223 participants aged 27 to 90 years (88 males and 135 females) from the North West Adelaide Health Study, who reported having pain, aching or stiffness in either of their feet on most days in the last month, completed the MFPDI by telephone interview. The proportion of people with disabling foot pain was determined using three definitions: (i) Definition A-at least one of the 17 items documented on at least some days in the last month; (ii) Definition B-at least one of the 17 items documented on most/every day(s) in the last month, and; (iii) Definition C-at least one of the ten functional limitation items documented on most/every day(s) in the last month. Cross-tabulations and chi-squared statistics were used to explore differences in responses to the MFPDI items according to age and gender. Results: The proportion of people with disabling foot pain according to each definition was as follows: Definition A (100%)...

BACKGROUND AND OBJECTIVES: Dialysis withdrawal (DW) in patients with ESRD is increasing in importance. This study assessed causes of death and risk factors for DW in Australia and New Zealand in the first year of dialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This retrospective observational cohort study included all adult Australians and New Zealanders beginning renal replacement therapy in 1999-2008. RESULTS: A total of 24,884 patients with 10,073 deaths were included. Deaths from cardiac and social causes (predominantly DW) accounted for 38% and 28% of all deaths, respectively. Cumulative incidence of DW was 3.5% at 1 year (95% confidence interval [CI], 3.3%-3.8%), 9.0% at 3 years (95% CI, 8.6%-9.4%), and 13.4% at 5 years (95% CI, 12.8%-13.9%). In multivariate analysis, predictors for DW in the first year were older age (subhazard ratio [SHR], 1.70 per decade [95% CI, 1.59-1.83]; P<0.001), late referral (SHR, 1.83 [95% CI, 1.59-2.11]; P<0.001), comorbid conditions (SHR, 1.33 per each additional comorbid condition [95% CI, 1.25-1.41]; P<0.001), and diabetes (SHR, 1.16 [95% CI, 1.00-1.34]; P=0.05). Negative predictors for DW included male sex (SHR, 0.75 [95% CI, 0.66-0.87]; P<0.001), indigenous ethnicity (SHR, 0.74 [95% CI...

BACKGROUND: The study aim was to determine whether age is an independent risk factor for survival from early invasive breast cancer in contemporary Australian clinical settings. METHODS: The study included 31 493 breast cancers diagnosed in 1998–2005. Risk of death from breast cancer was compared by age, without and with adjustment for clinical risk factors, using Cox proportional hazard regression. RESULTS: Risk of breast cancer death was elevated for cancers of larger size, higher grade, positive nodal status, oestrogen receptor negative status, vascular invasion and multiple foci. Ductal lesions presented a higher risk than other lesions. Adjusting for these factors, the relative risk of breast cancer death (95% confidence limits) was lower for 40–49-year-olds at 0.80 (0.66, 0.96) than for the reference category under 40 years, but higher for 70–79-year-olds at 1.64 (1.36, 1.98) and women aged 80 years or more at 2.19 (1.79, 2.69). The risk for 50–69-year-olds and women under 40 years was similar. Risk-factor adjustment reduced the difference in risk between the reference category under 40 years and 40–49-year-olds, largely eliminated the lower relative risk for 50–69-year-olds, and increased the relative risks for women aged 70–79 years and older. DISCUSSION: Survivals in women under 40 and over 70 years of age are poorer than for 40–69-year-olds. Research is needed into the best treatment modalities for younger women and older women with co-morbidity.; David M. Roder...

Observational studies have shown an increased lifetime risk of cardiovascular disease (CVD) in women who experienced a hypertensive disorder in pregnancy. This risk is related to the severity of the pregnancy-related hypertensive disease and gestational age at onset. However, it has not been investigated whether these differences in CVD risk factors are already present at postpartum cardiovascular screening. We evaluated postpartum differences in CVD risk factors in 3 subgroups of patients with a history of hypertensive pregnancy. We compared the prevalence of common CVD risk factors postpartum among 448 women with previous early-onset preeclampsia, 76 women with previous late-onset preeclampsia, and 224 women with previous pregnancy-induced hypertension. Women with previous early-onset preeclampsia were compared with women with late-onset preeclampsia and pregnancy-induced hypertension and had significantly higher fasting blood glucose (5.29 versus 4.80 and 4.83 mmol/L), insulin (9.12 versus 6.31 and 6.7 uIU/L), triglycerides (1.32 versus 1.02 and 0.97 mmol/L), and total cholesterol (5.14 versus 4.73 and 4.73 mmol/L). Almost half of the early-onset preeclampsia women had developed hypertension, as opposed to 39% and 25% of women in the pregnancy-induced hypertension and late-onset preeclampsia groups...

PRIMARY OBJECTIVE: To show that socio-economically dependent cultural bias distorts results of the status quo method of estimating age at first menstruation. METHODS: Questionnaires asking for menstrual status and the recalled age at menarche were distributed to approximately 1000 Javanese girls who attended junior and senior high schools in Malang. Age of participants ranged from 11.98 to 18.89 years. Probit analysis was applied to the status quo data while average menarcheal age recalled by girls > or =16 year old was also calculated. t-test, F-test, ANOVA and chi2 tests were applied to test significance of differences between groups. MAIN OUTCOMES AND RESULTS: Girls of low occupational status fathers (Group 1) had a probit average menarcheal age of 13.99 years (SD = 1.33, n = 524). Girls of medium occupational status fathers (Group 2), had a lower probit average menarcheal age (13.06 SD = 1.38, n = 315). Girls of fathers with the highest occupational score (Group 3) rarely reported premenarcheal status (less than 10% in all age groups studied) and the probit analysis of their reports yielded an unbelievable average of 9.61 (SD = 3.41, n = 157) years. Group 3 girls tend to report their menarcheal status incorrectly, probably due to a 'fashion' of appearing mature or to 'contagion' during filling out of a questionnaire. The recalled average menarcheal age of Group 3 females questioned when they were aged 16 years and above...

OBJECTIVE: Variation in dental service provision over time has been related to changes in factors such as oral health and demographics. Dentist factors such as age and cohort effects are also potential sources of influence. The aim of the study was to examine the operation of age, period, and cohort factors on variation in service rates. BASIC RESEARCH DESIGN: data were collected by a mailed survey of a random sample of 10% of male and 40% of female dentists from each state/territory of Australia in 1983-84, 1988-89. and 1993-94 with response rates of 73, 75 and 74% respectively. MAIN OUTCOME MEASURES: Data on main areas of service were obtained from a log of service items provided on a typical day. RESULTS: Poisson regressions of rates for the 10 main areas of service over time showed increased rates over the study period for diagnostic, preventive, endodontic, crown and bridge, general/miscellaneous and orthodontic services, and decreased rates of prosthodontic services. Goodness-of-fit tests indicated that models for periodontal and endodontic services had a good fit. However, only endodontic services were readily interpretable in terms of descriptive trends. While the age-period-cohort model was preferred, age-period and age-cohort models were also examined because of problems of identification with age-period-cohort models. Endodontic rates were higher among younger dentist birth cohorts...

Background: While menarche indicates the beginning of a woman's reproductive life, relatively little is known about the association between age at menarche and subsequent morbidity and mortality. We aimed to examine the effect of lower age at menarche on all-cause mortality in older Australian women over 15 years of follow-up. Methods: Data were drawn from the Australian Longitudinal Study of Ageing (n = 1,031 women aged 65-103 years). We estimated the hazard ratio (HR) associated with lower age at menarche using Cox proportional hazards models, and adjusted for a broad range of reproductive, demographic, health and lifestyle covariates. Results: During the follow-up period, 673 women (65%) died (average 7.3 years (SD 4.1) of follow-up for decedents). Women with menses onset < 12 years of age (10.7%; n = 106) had an increased hazard of death over the follow-up period (adjusted HR 1.28; 95%CI 0.99-1.65) compared with women who began menstruating aged ≥ 12 years (89.3%; n = 883). However, when age at menarche was considered as a continuous variable, the adjusted HRs associated with the linear and quadratic terms for age at menarche were not statistically significant at a 5% level of significance (linear HR 0.76; 95%CI 0.56 - 1.04; quadratic HR 1.01; 95%CI 1.00-1.02). Conclusion: Women with lower age at menarche may have reduced survival into old age. These results lend support to the known associations between earlier menarche and risk of metabolic disease in early adulthood. Strategies to minimise earlier menarche...

BACKGROUND Bone mineral density is known to decrease rapidly after the menopause. There is limited evidence about the separate contributions of a woman's age, menopausal status and age at menopause to the incidence of hip fracture. METHODS AND FINDINGS Over one million middle-aged women joined the UK Million Women Study in 1996-2001 providing information on their menopausal status, age at menopause, and other factors, which was updated, where possible, 3 y later. All women were registered with the UK National Health Service (NHS) and were routinely linked to information on cause-specific admissions to NHS hospitals. 561,609 women who had never used hormone replacement therapy and who provided complete information on menopausal variables (at baseline 25% were pre/perimenopausal and 75% postmenopausal) were followed up for a total of 3.4 million woman-years (an average 6.2 y per woman). During follow-up 1,676 (0.3%) were admitted to hospital with a first incident hip fracture. Among women aged 50-54 y the relative risk (RR) of hip fracture risk was significantly higher in postmenopausal than premenopausal women (adjusted RR 2.22, 95% confidence interval [CI] 1.22-4.04; p = 0.009); there were too few premenopausal women aged 55 y and over for valid comparisons. Among postmenopausal women...

OBJETIVO: comparar as características epidemiológicas e clínicas e a evolução pós-tratamento de mulheres com câncer de mama diagnosticadas antes ou após os 40 anos de idade. MÉTODOS: foi realizado um estudo retrospectivo, tipo caso-controle, com análise de informações obtidas dos prontuários de pacientes atendidas entre janeiro de 1994 e junho de 2004. Excluímos os casos com carcinomas intraductais e no estádio IV. Foram formados três grupos: pacientes com menos de 40 anos no diagnóstico (n=72), pacientes entre 40 e 50 anos (n=68) e pacientes com mais de 50 anos (n=75). Foram coletadas e analisadas informações sobre a idade no momento do diagnóstico, maior diâmetro das lesões, estadiamento clínico, tipo, grau histológico, presença de receptores hormonais e o estado dos linfonodos. O teste do chi2 foi empregado para variáveis qualitativas. Para as variáveis quantitativas que não apresentam distribuição normal (como número de gânglios axilares acometidos por metástases e tempo de seguimento), foi utilizado o teste de Kruskal-Wallis. Para a construção das curvas de sobrevida livre de doença e sobrevida global, foi utilizado o teste log-rank. RESULTADOS: não houve diferença na distribuição por estádios...

BACKGROUND: An adrenal crisis (AC) is a major cause of morbidity in hypoadrenal patients. However, there is little information available on the incidence and underlying causes of AC. METHODS: The aim of the present study was to describe the incidence of AC in New South Wales (NSW), Australia. Using a health department database, we selected de-identified data on all adults aged 20 years and over who were treated in any hospital in NSW between July1, 2000-June 30, 2011, with either a principal or secondary diagnosis of an AC. AC admission rates were calculated overall and within age categories. Frequencies of co-morbid diagnoses were analysed by age and sex groups. Poisson regression was used to assess the significance of the observed change in AC related admissions with age, while controlling for any secular trends by including year in the model. Chi sq tests were used to assess the differences in frequencies of categorical variables between groups. RESULTS: 824 patients received treatment for an AC in hospital, corresponding to 74.9 admissions/year. The majority (62.5%) of the patients were women and 52.8% were aged 60 years and over. Admission rates were significantly associated with increasing age (p < 0.0001). Patients in the 60-69...

Aims: To identify variables that explain the association between alcohol abstention and cognitive performance. We hypothesized that demographic and personality variables would be important for explaining the association in all age cohorts, but that health variables would be more important in the older age-cohorts. Design: Three age cohorts (20-24, 40-44, 60-64 years) were sampled randomly, yielding a total of 7485 participants, with data from 602 alcohol abstainers and 4158 light or moderate drinkers used in this study. Setting: The sample was drawn from the cities of Canberra and Oueanbeyan, Australia. Measurements: Scales measuring demographic, health and personality variables and cognitive and physical tests were administered. Participants drinking at hazardous or harmful levels were excluded from the analysis. Findings: A range of demographic and physical function measures were found to explain partially the finding of abstainers having lower cognitive test scores. The effects of independent variables were largest in the 60-64-year-old age group with a trend for physical variables such as lung function and grip strength to become more important in the older age groups. In the 20-24-year-olds, the majority of the effect remained unexplained. Conclusion: There is evidence that poorer cognitive test performance by abstainers reflects in part selection effects and poorer physical functioning...

Compara-se o crescimento do peso-idade e da altura-idade de 7.990 crianças de 0-11 anos, aleatoriamente selecionadas e medidas em 1981-1982 no Estado da Paraíba (nordeste do Brasil), com o de estudo global realizado no nordeste em 1974-1975, com as curvas de crescimento das referências nacional e internacional. Os resultados colocam em evidência um déficit de crescimento muito acentuado, sobretudo com relação à referência internacional. A 11 anos nítidas diferenças se manifestam: 8 ou 9 quilos para o peso, segundo o sexo, e em torno de 11 cm para a altura. Os déficits de crescimento observados poderiam ser atribuídos à grande seca de 1978-1983, em particular o déficit de crescimento do peso em função da idade. No entanto, o déficit de crescimento da altura em função da idade mostra a existência de alterações mais profundas e mais insidiosas, ao longo do crescimento, manifestando-se por má nutrição crônica, atribuída sobretudo a fatores de ordem estrutural socioeconômica. Constata-se, portanto, no decorrer da última década, que eles têm sido cada vez mais deteriorados, como testemunham as alterações do modelo de crescimento - ele mesmo exprimindo o agravamento da situação nutricional da região.; Growth in terms of weight/age and height/age of 7...

OBJECTIVES: Early infant mortality has not declined as rapidly as child mortality in many countries. Identification of risk factors for early infant mortality may help inform the design of intervention strategies. METHODS: Over the period 1994-97, 15 469 live-born, singleton infants in rural Nepal were followed to 24 weeks of age to identify risk factors for mortality within 0-7 days, 8-28 days, and 4-24 weeks after the birth. FINDINGS: In multivariate models, maternal and paternal education reduced mortality between 4 and 24 weeks only: odds ratios (OR) 0.28 (95% confidence interval (CI) = 0.12-0.66) and 0.63 (95% CI = 0.44-0.88), respectively. Miscarriage in the previous pregnancy predicted mortality in the first week of life (OR =1.98, 95% CI = 1.37-2.87), whereas prior child deaths increased the risk of post-neonatal death (OR =1.85, 95% CI 1.24-2.75). A larger maternal mid_upper arm circumference reduced the risk of infant death during the first week of life (OR = 0.88, 95% CI = 0.81-0.95). Infants of women who did not receive any tetanus vaccinations during pregnancy or who had severe illness during the third trimester were more likely to die in the neonatal period. Maternal mortality was strongly associated with infant mortality (OR = 6.43...

OBJECTIVE: To test whether relations between economic development, economic inequality, and child and youth homicide rates are sex- and age-specific, and whether a country's wealth modifies the impact of economic inequality on homicide rates. METHODS: Outcome variables were homicide rates around 1994 in males and females in the age ranges 0-4, 5-9, 10-14, 15-19 and 20-24 years from 61 countries. Predictor variables were per capita gross domestic product (GDP), GINI coefficient, percentage change in per capita gross national product (GNP) and female economic activity as a percentage of male economic activity. Relations were analysed by ordinary least squares regression. FINDINGS: All predictors explained significant variances in homicide rates in those aged 15-24. Associations were stronger for males than females and weak for children aged 0-9. Models that included female economic inequality and percentage change in GNP increased the effect in children aged 0-9 and the explained variance in females aged 20-24. For children aged 0-4, country clustering by income increased the explained variance for both sexes. For males aged 15-24, the association with economic inequality was strong in countries with low incomes and weak in those with high incomes. CONCLUSION: Relations between economic factors and child and youth homicide rates varied with age and sex. Interventions to target economic factors would have the strongest impact on rates of homicide in young adults and late adolescent males. In societies with high economic inequality...
