And Task

Three groups ( n = 54) of participants aged 17–26, 39–51 and 59–76 were asked to solve two types of concept problems to investigate the intellectual correlates of concept identification as a function of stage of learning in adulthood. Predictions derived from the Gf-Gc theory of Horn and Cattell were partially supported in each age group. Differential ability-performance relations as a function of stage of learning were considerably less potent in the elderly versus the young and middle aged. Comparisons both within and between age groups suggested that a dynamic picture of interactions among organismic and task-related variables is preferable, reflecting structural changes in such relationships with practice and cohort membership.

Abstract. Background: Several studies found a significant relationship between important sport events and suicidal behavior. Aims: We set out to investigate whether there is a significant relationship between the raw suicide rate and the most important international sports events (Olympic Games, FIFA World Cup, UEFA European Championship) in such an achievement-oriented society as the Hungarian one, where these sport events receive great attention. Method: We examined suicide cases occurring over 15,706 days between January 1, 1970, and December 31, 2012 (43 years), separately for each gender. Because of the age-specific characteristics of suicide, the effects of these sport events were analyzed for the middle-aged (30–59 years old) and the elderly (over 60 years old) generations as well as for gender-specific population groups. The role of international sport events was examined with the help of time-series intervention analysis after cyclical and seasonal components were removed. Intervention analysis was based on the ARIMA model. Results: Our results showed that only the Olympic Games had a significant effect in the middle-aged population. Neither in the older male nor in any of the female age groups was a relationship between suicide and Olympic Games detected. Conclusion: The Olympic Games seem to decrease the rate of suicide among middle-aged men, slightly but significantly.

Abstract Summary In Kyoto Prefecture, Japan, the number of hip fractures increased during 2013–2017 compared to 2008–2012. However, the estimated overall incidence rate increased only in femoral neck fractures in men aged ≥75 and women aged ≥85. Purpose The incidence rate of hip fractures in Japan has plateaued or decreased. We investigated the annual hip fracture occurrences in Kyoto Prefecture, Japan, from 2008 to 2017. Methods Patients aged 65 years and above who sustained hip fractures between 2008 and 2017 and were treated at one of the participating 11 hospitals were included. The total number of beds in these institutions was 3701, accounting for 21.5% of the 17,242 acute-care beds in Kyoto Prefecture. The change in incidence rate was estimated utilizing the population according to the national census conducted in 2010 and 2015. Results The total number of hip fractures was 10,060, with 47.5% femoral neck fractures and 52.5% trochanteric fractures. A decrease in number was seen only in trochanteric fractures in the group of 75- to 84-year-old women. The population-adjusted numbers of femoral neck fractures showed a significant increase in all age groups in men, whereas in women, there was an increase in femoral neck fractures in the ≥85 group and trochanteric fractures in the age group 65–74, and a decrease in trochanteric fractures in the age group 75–84. The estimated change in incidence rate showed an increase in femoral neck fractures in men aged ≥75 and women aged ≥85. Conclusion In Kyoto Prefecture, the number of hip fractures increased in the second half of the study period (2013–2017) compared to the first half (2008–2012). However, the incidence rate had not increased, except in femoral neck fractures in men aged ≥75 and women aged ≥85.

Judgment Condition

ABSTRACTIt has been suggested that an exaggeration of the target age effect is obtained when the same respondents judge multiple age groups rather than only one age group. In the present study each of 1200 undergraduates rated a young, middle-aged, or old target on the 32 bipolar adjective pairs of the Aging Semantic Differential (ASD; Rosencranz & McNevin, 1969). An additional 200 undergraduates rated all three target age groups on the ASD. The ASD was scored in terms of the three dimensions reported by its authors. In the isolated judgment condition young targets were rated highest on the Instrumental-Ineffective and Personal Acceptability-Unacceptability dimensions followed, in both cases, by middle-aged and then by old targets; on the Autonomous-Dependent dimension, middle-aged targets were rated higher than both young and old targets. The hypothesized exaggeration of the target age effect in the comparative judgment condition was obtained for the descriptive dimensions (Instrumental-Ineffective and Autonomous-Dependent) but not for the evaluative dimension (Personal Acceptability-Unacceptability) of the ASD. Possible explanations for why judgment context might affect descriptive but not evaluative assessments of target age groups are discussed.

Background: The aim of the study was to investigate changes in self-rated health (SRH) between different age groups and sexes over a 20-year period. Methods: Data were retrieved from the large longitudinal Health Survey of North Trøndelag, Norway, which includes data collected from more than 190,000 participants aged 20–70+ years between the years 1984 and 2008. Data were analysed using logistic regression and adjusted for sex. Results: From 1984 to 2008, the odds of scoring higher on SRH decreased by 46% in the youngest age group (20–29 years) and increased by approximately 35% in the middle-aged and older age groups (40–70+ years). When considering sex differences, women in most age groups scored lower than the men on their SRH. Conclusions: Our finding suggest a trending shift in SRH, with a reduction in the youngest age group (20–29 years) and an increase in the middle-aged and older age groups (40–70+ years). Despite the sex differences being small, our data indicate that in most age groups, women tend to score lower than men on their SRH. Future studies should focus on these trends to understand better the mechanisms underlying these changes in SRH and to follow future trends to see if the trend is reinforced or diminished.

OBJECTIVE: To analyze the impact on human health of exposure to particulate matter emitted from burnings in the Brazilian Amazon region. METHODS: This was an ecological study using an environmental exposure indicator presented as the percentage of annual hours (AH%) of PM2.5 above 80 μg/m3. The outcome variables were the rates of hospitalization due to respiratory disease among children, the elderly and the intermediate age group, and due to childbirth. Data were obtained from the National Space Research Institute and the Ministry of Health for all of the microregions of the Brazilian Amazon region, for the years 2004 and 2005. Multiple regression models for the outcome variables in relation to the predictive variable AH% of PM2.5 above 80 μg/m3 were analyzed. The Human Development Index (HDI) and mean number of complete blood counts per 100 inhabitants in the Brazilian Amazon region were the control variables in the regression analyses. RESULTS: The association of the exposure indicator (AH%) was higher for the elderly than for other age groups (β = 0.10). For each 1% increase in the exposure indicator there was an increase of 8% in child hospitalization, 10% in hospitalization of the elderly, and 5% for the intermediate age group, even after controlling for HDI and mean number of complete blood counts. No association was found between the AH% and hospitalization due to childbirth. CONCLUSIONS: The indicator of atmospheric pollution showed an association with occurrences of respiratory diseases in the Brazilian Amazon region, especially in the more vulnerable age groups. This indicator may be used to assess the effects of forest burning on human health.

Objectives. Surgery is the most effective treatment for pancreatic cancer. However, present literature varies on outcomes of curative pancreatic resection in the elderly. The objective of the study was to evaluate age as an independent risk factor for 90-day mortality and complications after pancreatic resection. Methods. Nine hundred twenty-nine consecutive patients underwent 934 pancreatic resections between March 1995 and July 2014 in a tertiary care center. Primary analyses focused on outcomes in terms of 90-day mortality and postoperative complications after pancreatic resection in these two age groups. Results. Even though patients aged 75 years or older had significantly more postoperative morbidities compared with the younger patient group, the age group was not associated with increased risk of 90-day mortality after pancreatic resection. Discussion. The study suggests that age alone should not preclude patients from undergoing curative pancreatic resection.

The Relationship

Vitamin D requirements are thought to vary with age, but there is little comparative evidence for this. One goal in establishing a vitamin D requirement is to avoid secondary hyperparathyroidism. We studied 1741 euthyroid, thyroid clinic outpatients without evidence of calcium abnormalities, ranging in age from 19 to 97 yr, whose serum and urine had been analyzed for calcium, vitamin D, and parathyroid status. We found no effect of age on the 25-hydroxyvitamin D [25(OH)D] concentration associated with specific vitamin D intakes, and there was no relationship between 25(OH)D and 1,25hydroxyvitamin D [1,25(OH)2D]. In every age group, serum 1,25(OH)2D declined with increasing creatinine (P < 0.001). What changed with age included creatinine, which correlated with 25(OH)D (r = 0.146, P < 0.001) only in the youngest age group (19–50 yr) but not in the older age groups (P > 0.1). Creatinine did not correlate with PTH in the youngest age group, but the relationship became significant as age increased (e.g. for the elderly, r = 0.365, P < 0.001). Linear regression of log PTH vs. log 25(OH)D agreed with the natural shape of the relationship observed with scatterplot smoothing, and this showed no plateau in PTH as 25(OH)D increased. We compared PTH concentrations among age groups, based on 20 nmol/liter increments in 25(OH)D. Mean PTH in adults older than 70 yr was consistently higher than in adults younger than 50 yr (P < 0.05 by ANOVA and Dunnett’s t test). PTH levels of the elderly who had 25(OH)D concentrations greater than 100 nmol/liter matched PTH of younger adults having 25(OH)D concentrations near 70 nmol/liter. This study shows that all age groups exhibit a high prevalence of 25(OH)D insufficiency and secondary hyperparathyroidism. Older adults are just as efficient in maintaining 25(OH)D, but they need more vitamin D to produce the higher 25(OH)D concentrations required to overcome the hyperparathyroidism associated with their diminishing renal function.

The purpose of this study was to describe the effect of age on specific psychological and behavioral measures of learned-helpless and mastery-oriented students. The study consisted of two age groups, younger and older, of learned-helplessness and mastery-oriented students. Within each age group, learned-helpless and mastery-oriented students were compared in terms of attributional profiles and levels of task persistence during instruction. Students were asked to view videotapes of their performances, to describe how they thought they did on each task, and to give reasons for their performance. Responses were classified into four attributional categories: (a) ability, (b) effort, (c) task difficulty, and (d) environment or luck. Persistence was also determined by looking at the number of times students would attempt a task. Attributional profiles and task persistence associated with the leamed-helpless condition was more prevalent with the older group than with the younger group.

Two Age Groups

18597 Background: In industrial countries, the cancer burden of the elderly is high and is increased. One reason is longer life expectancy. Increasing age standardized rates of cancer in this age group compared to younger groups may also explain this phenomenon. Methods: Two age groups were examined, above and below 65 years. Each age group was further divided into men and women. The age standardized rates for all cancers combined among the Jewish population in Israel were identified through the Israel Cancer Registry during the years 1973–2002. In addition, lung and colorectal cancers according to sexes, prostate cancer in men and breast cancer in women were examined. Results: Between the first 5 years of the study (1973–1977) and the last 5 years (1998–2002) the age standardized rates for all cancers combined were raised by about one third in the two age groups. In males, the overall change was higher in the older group (42% in men aged 65 years and older compared to 31% in men younger than 65). However, the rise in the younger group was more prominent in females (42% in women younger than 65 years compared to 33 % in women aged 65 and older). The most outstanding increase was in prostate cancer in men, but mainly in the younger group (176% in the older group and 368% in the younger group) followed by breast cancer in women, more prominent in the older group (64% in the older group and 50% in the younger group). In both sexes, more noticeable increases were noted in the older groups in colorectal cancer and in lung cancer. Between the years 1993–1997 and 1998–2002 shifts towards stabilization and even a decrease was noted in some of the cancers that were examined. In men aged 65 years and older rates for all cancers combined were decreased by 2.5%, among the specific tumors and a decrease was noted in lung cancer (6.7%) and prostate cancer (5.8%). The rates for all cancers combined among the older women were slightly decreasing (2.0%). No decrease was noted in the specific tumors in this group. Among the younger groups in both sexes, no decrease (defined >0.5%) was noted. Conclusions: These data argue against the hypothesis that the overall change in the cancer burden in the aged could be also explained by differences changes in the risk of developing cancer between these two age groups. No significant financial relationships to disclose.

IntroductionSuicide risk is increased in patients with a history of psychiatric hospitalization.AimTo explore how suicide risk varies by age during psychiatric hospitalization and in the year post-discharge.MethodsThis is a population-based case-control study of all suicides (n = 20,675; 70% male) in Sweden aged ≥18 years during 1991–2003. Each suicide was individually matched to 10 population controls by age, sex, and county of residence. Discharge diagnoses of a mental disorder (except dementia and other organic disorders) in the year prior to suicide were identified by register linkage. Odds ratios (OR) were calculated by conditional logistic regression to estimate the relative risk of suicide in those with psychiatric diagnoses compared to the general population. ORs were estimated by age group (18–34 years, 35–49 years, 50–64 years, and ≥ 65 years) and timing of the suicide in relation to discharge.ResultsDuring hospitalization, the youngest age group had the greatest suicide risk elevation [OR 64 (95% CI 44-92)]. In the first month post-discharge, the oldest age group had the highest suicide risk elevation [OR 162 (95% 66–399) in the first week and OR 127 (95% 67–242) in the second to fourth weeks]. In the remaining eleven months, suicide risk elevation was lower and relatively similar in different age groups.ConclusionsDuring the year following psychiatric hospitalization, an especially high attention should be paid to the suicide risk of the elderly patients in the first month post-discharge.
