Changes in Jewish mortality and survival, 1963–1987

Abstract

From information on mortality of Jews obtained from individual death certificates and population data from surveys of the Jewish population undertaken in 1963 and 1987, age‐specific death rates and life expectancy of the Jewish population of Rhode Island are compared with those of the total white population for 1963 and 1987 to assess changing differentials. The Jewish mortality experience continues to differ from that of the larger population even while both groups have experienced noticeable improvements. For males, the age standardized rates have widened in favor of Jews as have the life expectancies at birth and the percentage surviving to old age. By contrast, for females, the standardized death rate has widened considerably in favor of whites, while life expectancy has improved almost identically for both groups and therefore remained about equal, as it was in 1963. Reasons for these patterns are explored through attention to differences between Jews and the general white population in death rates at particular stages of the life cycle. Jews tend to be more advantaged at all but the most advanced ages, age groups in which proportionally more of the Jewish population and Jewish deaths are concentrated.     

Incidence,trends, and survival of oropharyngeal squamous cell cancer in Aotearoa New Zealand, 2006–2020

BackgroundAn increasing trend of oropharyngeal cancer (OPC) has been reported in several countries with different demographic characteristics, and often attributed to increases in human papillomavirus (HPV) infection. The survival of patients with OPC has steadily improved, especially for those with positive HPV status. This study assessed the incidence, trends, and survival of OPC in Aotearoa New Zealand (NZ) by age at diagnosis, sex and ethnicity.MethodsThe study included all 2109 patients resident in NZ with a primary diagnosis of oropharyngeal squamous cell carcinoma from 2006 to 2020, identified from the National Cancer Registry. We assessed age-standardised incidence rate (ASR), annual percent change (APC) and overall and relative survival rates.ResultsThe average annual incidence of OPC was 2.2 per 100,000 population. There was a steady increase of 4.9% per year over 15 years. Although the incidence rates were higher in males over the study period, the overall rate of increase was similar in males (4.9%) and in females (4.3%). The incidence was highest in the 50–69-year group (8.8/100,000 population). This age group had an incidence that increased by 7.5% per year to 2018, and then declined. The main increase in rates was seen between the birth cohort of 1946–50 and that of 1956–60. The increase in incidence was seen in Māori and Pākehā/European populations, but no increase was seen in Pacific or Asian populations. The 5-year overall relative survival rate improved from 69% in 2006‐13 to 78% in 2014–20. Survival rates were lower in older patients, females, and Māori patients.ConclusionThis study confirmed a substantial increase in OPC incidence in NZ, with some evidence to suggest a recent slowing in this increase. Māori and Pākehā/European had the highest incidence, while Pacific and Asian populations showed the lowest rates and no increase over the study period. Survival rates have improved over time, but remained lower in some demographic groups.     

Trends in schistosomiasis-related mortality in Brazil, 2000–2011

Schistosomiasis is an important public health problem, with high morbidity and mortality in endemic countries. We analysed the epidemiological characteristics and time trends of schistosomiasis-related mortality in Brazil. We performed a nationwide study based on official mortality data obtained from the Brazilian Mortality Information System. We included all deaths in Brazil between 2000 and 2011, in which schistosomiasis was mentioned on the death certificate as an underlying or associated cause of death (multiple causes of death). We calculated crude and age-adjusted mortality rates (per 100,000 inhabitants), and proportional mortality rates. Trends over time were assessed using joinpoint regression models. Over the 12-year study period, 12,491,280 deaths were recorded in Brazil. Schistosomiasis was mentioned in 8,756 deaths, including in 6,319 (72.2%) as an underlying cause and in 2,437 (27.8%) as an associated cause. The average annual age-adjusted mortality rate was 0.49 deaths/100,000 inhabitants (95% confidence interval: 0.46–0.52) and proportional mortality rate was 0.070% (95% confidence interval: 0.069–0.072). Males (0.53 deaths/100,000 inhabitants), those aged ⩾70 years (3.41 deaths/100,000 inhabitants), those of brown race/colour (0.44 deaths/100,000 inhabitants), and residents in the Northeast region of Brazil (1.19 deaths/100,000 inhabitants) had the highest schistosomiasis-related death rates. Age-adjusted mortality rates showed a significant decrease at a national level (Annual Percent Change: −2.8%; 95% confidence interval: −4.2 to −2.4) during the studied period. We observed decreasing mortality rates in the Northeast (Annual Percent Change: −2.5%; 95% confidence interval: −4.2 to −0.8), Southeast (Annual Percent Change: −2.2%; 95% confidence interval: −3.6 to −0.9), and Central-West (Annual Percent Change: −7.9%; 95% confidence interval: −11.3 to −4.3) regions, while the rates remained stable in the North and South regions. Despite the reduced mortality, schistosomiasis is still a neglected cause of death in Brazil, with considerable regional differences. Sustainable control measures should focus on increased coverage, and intensified and tailored control measures, to prevent the occurrence of severe forms of schistosomiasis and associated deaths.     

Primary liver cancer incidence and survival in ethnic groups in England, 2001–2007

Background: The patterns of primary liver cancer incidence and survival are not known for detailed ethnic groups within the UK. Methods: Data on patients resident in England diagnosed with primary liver cancer (ICD-10 C22) between 2001 and 2007 were extracted from the National Cancer Data Repository. Age-standardised incidence rate ratios (IRRs) were calculated for different ethnic groups separately for males and females, using the White ethnic groups as baselines. Overall survival was analysed using Cox regression, adjusting sequentially for age, socioeconomic deprivation and co-morbidity. Results: Ethnicity data were available for 75% (13,139/17,458) of primary liver cancer patients. Compared with the White male baseline, Chinese males had the highest IRR. Black African, Bangladeshi, Pakistani and Indian men also had statistically significant high IRRs. Black Caribbean men had a marginally elevated incidence rate compared with White men. In comparison with White women, Pakistani women had the highest IRR. Bangladeshi, Chinese, Black African and Indian women also had high IRRs. As observed in men, Black Caribbean women had an incidence rate closer to that of White women. Pakistani men and women, Black African women and Chinese men had statistically significantly better survival compared with their White counterparts. Conclusion: The variation found in the incidence of primary liver cancer, could be due to established risk factors such as hepatitis B and C infection being more prevalent among certain ethnic groups. Country of birth, age at migration and length of stay in England are likely to be important factors in this disease, and future research should examine these where possible.     

Renal cell cancer in Israel: Sex and ethnic differences in incidence and mortality, 1980–2004

Background: The causes of renal cell cancer (RCC) remain largely unexplained. While the incidence is generally higher in men than in women, little has been reported on ethnic differences. We examine trends in RCC incidence and mortality rates among Israeli Arab and Jewish populations and compared with the rates in other countries. Methods: Age-adjusted RCC incidence and mortality rates in Israel, during 1980–2004, were calculated by sex and population group, using the National Cancer Registry. They were compared with the United States based on the Surveillance Epidemiology and End Results [SEER] program and the IARC database for international comparisons. Results: While RCC incidence rates in Israel are similar to the United States and the European average, the rates are significantly higher among Israeli Jews than Arabs. Men are affected more than women. Incidence rates over the last 24 years have increased among all men and Jewish women, but not among Arab women. Among men, the incidence rate ratio for Jews to Arabs declined from 3.96 in 1980–1982 to 2.34 in 2001–2004, whereas for women there was no change. The mortality rates were higher among Jews than Arab and among men than women. There were no significant change in the mortality rates and rate ratios. Conclusions: Our findings demonstrate marked ethnic differences in RCC in Israel. The lower incidence among Arabs stands in contrast to the higher prevalence of potential risk factors for RCC in this population group. Genetic factors, diet and other lifestyle factors could play protective roles.     

Trends in cancer incidence in the Republic of Mauritius, 1991–2015

IntroductionMauritius, a small state, is among the few African countries where cancer registration is population based and nationwide. We reported trends in cancer incidence for twenty five years as well as the mortality to incidence ratio (MIR) as main quality indicator of the Mauritius National Cancer Registry (MNCR).Materials and methodsWe calculated age standardised incidence rates (ASRs) of cancers by sex and by 5 year age group for five successive year periods from 1991 to 2015. The average annual percentage change (AAPC) were determined by sex and cancer sites. MIRs were compared for the period 2001–2004 and 2012–2015.ResultsIn males, the most common cancer sites (in terms of ASRs per 100,000) were those of the colon-rectum (17.0), prostate (16.5), trachea-bronchus-lung (13.0), stomach (8.4) and lip-oral cavity-pharynx (7.7). The AAPC were +3.9%, +4.2%, +0.5%, -0.1% and -1.3% respectively. In females, the most frequent sites were breast (53.7), colon-rectum (13.2), cervix uteri (11.2), corpus uteri (7.7) and ovary (5.7). The AAPC were +3.4%, +4.4%, -2%, +5.2% and -0.1% respectively. The most significant decrease in MIRs among males were liver (1.9 to 1.0), stomach (1.3 to 0.8) and lung (1.7 to 1.2) cancers while among females, they were pancreas (3.4 to 1.3), liver (1.8 to 1.2) and stomach (1.5 to 0.8) cancers.ConclusionThe most common cancers were those associated with 'westernisation' of lifestyle. Our figures contrast with other Sub-Saharan Africa countries where infection related cancers are most predominant. The MNCR has also improved its data quality over time.     

Distribution and abundance of the hedgehog (Erinaceus europaeus) L. in New Zealand, 1869–1973

An account is given of early liberations and the spread of hedgehogs throughout New Zealand between 1869 and 1973. Evidence, gathered largely from questionnaires and personal observations, is summarised in tables and maps to show the present range and abundance of the species. Hedgehogs dispersed from many points of liberation; their numbers increased dramatically in the South Island between 1910 and 1940, and in the North Island between 1920 and the 1950s. By the 1940s they had colonised most of the lowland areas, and their range had extended to the foot of the bushed mountainous regions; a few were found at altitudes of 2000 m. Since 1948 they have extended their range a little to include parts of the central volcanic plateau of the North Island, areas of inland Nelson, and northern Westland. Their numbers appear to have stabilised over the past 25 years. Today, hedgehogs are most abundant in intensively farmed lowland districts, towns, and suburbs. They become less numerous with increasing altitude, and few are encountered above 800 m or in wet, bushed areas. They are absent from areas where rainfall exceeds 250 cm/year or where more than 250 frosts occur annually. Factors limiting the abundance of hedgehogs in New Zealand are discussed.     

Trends in regional cancer mortality in Taiwan 1992–2014

BackgroundAlthough the cancer mortality rate in Taiwan has been declining in recent years, no study has yet reported any regional differences in cancer mortality rates in Taiwan. We hypothesized that regional cancer mortality rates in Taiwan, an ethnically homogeneous society, exhibited no significant variations.MethodsWe investigated the trends in Taiwan regional cancer mortality between 1992 and 2014. We analyzed regional age-standardized cancer mortality rates for lung, liver, colon, stomach, oral, breast, and prostate cancers using the Taiwan Longitudinal Health Insurance Database and Demographic Database. Furthermore, we applied Joinpoint regression analysis to evaluate the trends across different regions.ResultsThere are clear regional variations in mortality rates for liver, stomach, and oral cancers, but not for lung, colon, breast, and prostate cancers. The regional death rates of oral cancer, especially for eastern Taiwan, not only elevate the fastest (APC = 14.78% per year, P < 0.001) but also show the largest disparities between men and women. Regional death rates for stomach cancer, which declined most rapidly, are converging in both general and gender groups. Liver cancer is the only one with regional variations whose trends do not all go in the same direction. We also demonstrated that northern Taiwan has significant regional advantages with respect to cancer mortality.ConclusionsSome but not all cancers in Taiwan show regional disparities. Liver, stomach, and oral cancers in Taiwan exhibit clear regional variations in mortality rates. In particular, the regional variations in oral cancer mortality rates are consistent with those in alcohol consumption.     

Prevalence and Trends in Obesity among China’s Children and Adolescents, 1985–2010

Objectives

We examined the prevalence of and trends in obesity among children and adolescents in China (1985–2010).

Methods

We used data from the 1985, 1991, 1995, 2000, 2005, and 2010 Chinese National Surveys on Students’ Constitution and Health (CNSSCH). The CNSSCH is a national survey of physical fitness and health status in Chinese students that uses multistage stratified sampling of 31 provinces and municipalities. A subject was considered obese or overweight if weight-for-height exceeded the 20% or 10% of standard weight-for-height. The standard weight-for-height was the 80th percentile for sex- and age-specific growth charts.

Results

The age-adjusted prevalence of obesity and of overweight and obesity combined was 8.1% (95% CI, 8.0–8.3%) and 19.2% (95% CI, 19.1–19.4%) among children and adolescents 7–18 years in age. Obesity was more likely to be present among children or adolescents who were male (RR, 1.93; 95% CI, 1.90–1.97), urban (RR, 1.99; 95% CI, 1.95–2.02), or 10–12 years (RR, 1.43; 95% CI, 1.40–1.46). Trend analyses of the 25-year period revealed a significant increasing trend in males (RR, 1.59; 95% CI, 1.58–1.60) and in females (RR, 1.49; 95% CI, 1.48–1.50). The rate of increase in obese or overweight prevalence was highest in boys from rural areas (9% annual increase).

Conclusions

During 1985–2010, there was a significant and continuous increase in the prevalence of obesity in children and adolescents. Obesity is epidemic in China, but may be reduced with evidence-based interventions (e.g., school intervention programs).     

Trends in colorectal cancer incidence in Ho Chi Minh City,Vietnam (1996–2015): Joinpoint regression and age–period–cohort analyses

BackgroundLittle is known about the trends in colorectal cancer (CRC) in Vietnam. We aimed to investigate the trends in epidemiology and anatomical subsites of CRC in Ho Chi Minh City, Vietnam.MethodsBased on the Ho Chi Minh City Cancer Registry data during 1996–2015, we calculated the average annual percent changes (AAPCs) of the age-standardized incidence rates (ASRs) by sex, age groups, and anatomical subsites, using joinpoint regressions analysis. We further performed age–period–cohort (APC) analysis using the United States National Cancer Institute’s web-based statistical tool to explore the underlying reason for the incidence trend.ResultsOver 20 years the overall ASR of CRC increased from 10.5 to 17.9 per 100,000, a 1.7-fold increase. CRC incidence elevated more rapidly in men (AAPC 4.7, 95%CI 2.2–7.3) than in women (AAPC 2.6, 95%CI 0.6–4.8). The highest and lowest increasing rates of ASRs were observed in the 50–64-year-old age group (AAPC 5.3, 95%CI 2.8–7.9) and < 50-year-old age group (AAPC 1.1, 95%CI –0.7 to 2.9), respectively. Regarding subsites, rectal cancer had the highest rate of increase (AAPC 3.3, 95%CI 1.0–5.7). Furthermore, the APC analysis indicated significant increases in CRC incidence in birth cohorts after 1975 in both genders.ConclusionsThe CRC incidence in Ho Chi Minh City increased, with the more prominent rates being among men and older populations, in rectal subsites, and in people born after 1975. The upward trend of CRC incidence in Ho Chi Minh City may be due to the adoption of a westernized lifestyle.     

Temporal trends in incidence of childhood cancer in Switzerland, 1985–2014

BackgroundIncidence of childhood cancer increased in most countries worldwide, but reasons are unclear. This study investigates trends of childhood cancer incidence in Switzerland from 1985 to 2014.MethodsWe extracted data on all childhood cancer cases diagnosed at ages 0–14 years in Switzerland from the Swiss Childhood Cancer Registry. We included ICCC-3 main groups I-XII and calculated age-standardised, cumulative, and age-specific incidence for different diagnostic groups. We analysed trends of annual age-standardised incidence using JoinPoint regression models.ResultsOver the study period from 1985 to 2014, 5104 of 5486 cancer diagnoses (93%) were microscopically verified. The proportion of children treated in paediatric cancer centres increased from 84% during 1985–1994 to 93% in 1995–2004 and 98% in 2005–2014 (p < 0.001). Using the World standard population, age-standardised incidence was 143 in 1985–1994, 154 in 1995–2004, and 162 per million in 2005–2014. Incidence increased by 0.7% (95% confidence interval (CI) 0.5; 1.0) per year for all cancers from 1985 to 2014, 0.8% (95% CI 0.2%–1.4%) for leukaemias over the same period, 3.0% (95% CI 0.2%–1.4%) for CNS tumours during 1985–2002, and 3.8% (95% CI 1.7%–6.0%) for epithelial neoplasms and melanomas over the period 1985–2014.ConclusionTrends in incidence were driven mostly by increases among leukaemias and CNS tumours. For CNS tumours, observed trends may be explained at least partially by diagnostic changes and improved registration. For leukaemias, rising incidence may be real and due to risk factors that experience similar increases in trends.     

Regional trends in prostate cancer incidence,treatment with curative intent and mortality in Norway 1980–2007

Objectives: To compare the trends in prostate cancer incidence, treatment with curative intent and mortality across regions and counties in Norway, and to consider changes in incidence (an indicator for early diagnosis) and treatment with curative intent as explanatory factors for the decreasing prostate cancer mortality rates. Patients and methods: Prostate cancer incidence and mortality data (1980–2007) alongside treatment data (1987–2005) were obtained from the national, population-based Cancer Registry of Norway. Joinpoint regression models were fitted to age-adjusted incidence, treatment and mortality rates to identify linear changes in the trends. Results: Both age-adjusted incidence rates and rates of curative treatment of prostate cancer increased significantly in all five regions of Norway since the early 1990s. There was a strong positive correlation between increasing incidence and increasing use of curative treatment. The frequency of curative treatment in Western Norway was almost threefold that in the Northern and Central regions around year 2000. Subsequently, the regional trends converged and only minor differences in prostate cancer incidence and use of curative treatment were observed by 2005. The declines in mortality were observed earliest in the regions with the highest incidence and the most frequent use of curative treatment, while the largest decreases in mortality were found in counties where the largest increases in curative treatment were observed. Conclusions: The elucidation of the prostate cancer mortality trends is hindered by an inability to tease out the potential effects of early treatment from the more general impact of improved and more active treatment. However, it is likely that both sets of intervention have contributed to the decline in prostate cancer mortality in Norway since 1996.     

Jewish mortality and survival patterns: Providence,Rhode Island, 1962–1964

Abstract

Galton believed that his data on hereditary genius support purely genetic inheritance. On the contrary, analysis under a simple model shows no clear resolution of genetic and cultural inheritance in this material, or generally, unless adoptive relations, monozygous twins, and/or environmental indices are included in a design adequate to test the assumptions under which they are informative.     

Growth of opossums (Trichosurus vulpecula) in the Orongorongo Valley,Wellington, New Zealand, 1953–61

The growth of pouch young and juvenile Trichosurus vulpecula to maturity is described, based on animals gin‐trapped in 800 ha of indigenous forest in the Orongorongo Valley, near Wellington. Commencing in March 1953 opossums were trapped continuously for 1 year, and then intermittently until 1961. Four ageing criteria were considered: ossification of limb epiphyses and development of cranial ridges were unreliable; tooth wear and closure of the spheno‐occipital skull sutures were more satisfactory, and were adopted. For the first 180 days the mean growth followed a rectilinear regression when size, expressed as cube root of weight, was plotted against age. Thereafter growth accelerated greatly, but steadied towards the end of the first year; its rate increased after several months, and ceased at 2 to 21/2 years. Though adult males (2.65 kg) and females (2.41 kg) differed significantly in weight, there was no detectable difference during the growth phase. Births occurred throughout the year, but were markedly seasonal, 86% occurring between mid March and the end of May. A secondary birth peak in spring, recorded in other areas, was barely apparent. Most young consequently grew fastest in their first spring and summer. The growth pattern appeared to be mainly dependent on age rather than season_^ since all young reared in captivity conformed, irrespective of the season of birth.     

Secular trends in incidence and mortality of bladder cancer in China, 1990–2017: A joinpoint and age-period-cohort analysis

BackgroundBladder cancer is closely related to occupational carcinogens, and China is undergoing a rapid industrialization. However, trend of bladder cancer incidence and mortality remains unknown in China.MethodsIncidence and mortality rates of bladder cancer (1990–2017) were collected for each 5-year age group stratified by gender (males/females) from the Global Burden of Disease (GBD) 2017 study. The average annual percentage change (AAPC) of rates were analyzed by joinpoint regression analysis; age, period and cohort effects on incidence and mortality were simultaneously estimated by age-period-cohort model.ResultsThrough 1990–2017, age-standardized incidence rates significantly rose in men (AAPC = 0.72%, 95% CI: 0.5%, 0.9%) while decreased in women (-1.25%: -1.6%, -0.9%); age-standardized mortality rates decreased in both men (-1.09%: -1.2%, -0.9%) and women (-2.48%: -2.8%, -2.2%). The joinpoint regression analysis showed the mortality almost decreased in all age groups; while the incidence increased in men for older age groups (from 45 to 49 to 80–84). Moreover, age effect showed the incidence and mortality increased with age; the incidence and mortality increased with time period, while in women period effect stop decreasing and began to increase since 2007; cohort effect showed them decreased with birth cohorts.ConclusionsThe incidence of bladder cancer is increasing in men but mortality decreases in both sexes. Both the incidence and mortality in men substantially increase with age and period, while the rates in women increased with period since 2007. The period effect may indicate the increased risks to bladder cancer in Chinese men. Etiological studies are needed to identify the factors driving these trends of bladder cancer.     

Malignant pleural mesothelioma incidence and survival in the Republic of Ireland 1994–2009

ObjectiveMalignant pleural mesothelioma (MPM) is a rare malignancy associated with exposure to asbestos. The protracted latent period of MPM means that its incidence has continued to rise across Europe after the introduction of restrictions on asbestos use. In order to obtain a clearer indication of trends in the Republic of Ireland (ROI), incidence and survival were assessed based on all MPM cases reported since the establishment of the National Cancer Registry of Ireland (NCR).MethodsNCR recorded 337 MPM diagnoses in the ROI during 1994–2009. Survival was assessed for all cases diagnosed with adequate follow-up (n = 330). Crude and European age-standardized incidence rates were calculated for all cases and for 4-year periods. A Cox model of observed (all-cause) survival was used to generate hazard ratios for the effect of: gender; age at diagnosis; diagnosis cohort; region of residence; histological type; and tumour stage. Single P-values for the variables indicated were calculated using either a stratified log-rank test or stratified trend test.ResultsOver the study period the age-standardized MPM incidence in the ROI rose from 4.98 cases per million (cpm) to 7.24 cpm. The 1-year survival rate for all MPM cases was 29.6% (CI 24.7–34.6%). Excess mortality risk was associated with age at diagnosis (75–89 yrs vs. 55–64 yrs, HR 1.88, 95% CI 1.35–2.63, P < 0.001) and tumour stage (III vs. I HR 1.57, 95% CI 1.00–2.48, P < 0.05; IV vs. I HR 1.55, 95% CI 1.08–2.21, P < 0.05). Age showed a significant survival trend (P < 0.001) but tumour stage did not (P = 0.150). There was significant heterogeneity between the survival of patients resident in different regions (P = 0.027).ConclusionMPM incidence and mortality continued to rise in the ROI after the restrictions on asbestos use and the predictors of survival detected in this study are broadly consistent with those identified for other countries.
