Identifying social outcomes of importance for childhood cancer survivors: an e-Delphi study.

PURPOSE: Childhood cancer survivors (CCS) are at risk of deficits in their social outcomes, a key aspect of overall health and quality of life. Social outcomes of import are ill-defined leading to potential gaps in research and service provision. In this study, we undertook a preliminary consensus seeking exercise to support the development of a framework of the important social outcomes for CCS. METHODS: A modified e-Delphi study was conducted with four groups: CCS, health professionals, social workers and teachers. Round 1, developed from a literature review, included 34 questions rated for importance on a 7-point Likert scale. Rounds 2 and 3 presented items not achieving consensus, additionally proposed items and in round 3, a ranking question. RESULTS: Survey 1 was completed by 38 participants, 31 (82%) completed survey 2 and 28 (76%) completed survey 3. A total of 36 items were prioritised across 6 domains (education, independence, work, relationships, community, lifestyle), together forming the final list of social outcomes. Of these, 22 items met consensus for importance. Items rated most important were "having autonomy" and "avoiding social isolation". Quantitative and qualitative results reflected that social outcomes for survivors and general public should be the same. CONCLUSION: We have generated initial consensus on important social outcomes for CCS, highlighting the need for these to be matched to those of the general population. It suggests strategies are required to ensure autonomy and appropriate support for independence and relationships are provided through long-term aftercare and beyond. Further work is needed to validate and develop these findings into a framework to support appropriate social aftercare for CCS.

Following treatment for childhood cancer, survivors may face problems with their social health. These are the parts of life, besides physical and mental health, that help people to lead full, happy and satisfied lives. Social health is important as it affects all areas of our lives and includes many areas such as education, work and relationships. It is essential that we understand what the most important areas of social health are for childhood cancer survivors so that we can support these. This will help survivors lead the lives they want as adults. In this study, 38 childhood cancer survivors, children's cancer doctors and nurses, social workers and teachers took part in a series of questionnaires designed to collect their views about social health for survivors. Participants established 22 areas of social health to be very important. 'Having autonomy' and 'avoiding social isolation' were selected as the most important. Participants felt that the aspects of social health which are important to survivors are the same outcomes as for the wider public. However, survivors may face many barriers to doing well in these areas. To fully identify the important areas of social health for childhood cancer survivors, we need to undertake further work to understand the views of other important groups, such as parents or carers. We also need to explore the barriers survivors face in achieving good social health.

Socio-economic and ethnic disparities in childhood cancer survival, Yorkshire, UK.

BACKGROUND: Establishing the existence of health inequalities remains a high research and policy agenda item in the United Kingdom. We describe ethnic and socio-economic differences in paediatric cancer survival, focusing specifically on the extent to which disparities have changed over a 20-year period. METHODS: Cancer registration data for 2674 children (0-14 years) in Yorkshire were analysed. Five-year survival estimates by ethnic group (south Asian/non-south Asian) and Townsend deprivation fifths (I-V) were compared over time (1997-2016) for leukaemia, lymphoma, central nervous system (CNS) and other solid tumours. Hazard ratios (HR: 95% CI) from adjusted Cox models quantified the joint effect of ethnicity and deprivation on mortality risk over time, framed through causal interpretation of the deprivation coefficient. RESULTS: Increasing deprivation was associated with significantly higher risk of death for children with leukaemia (1.11 (1.03-1.20)) and all cancers between 1997 and 2001. While we observed a trend towards reducing differences in survival over time in this group, a contrasting trend was observed for CNS tumours whereby sizeable variation in outcome remained for cases diagnosed until 2012. South Asian children with lymphoma had a 15% reduced chance of surviving at least 5 years compared to non-south Asian, across the study period. DISCUSSION: Even in the United Kingdom, with a universally accessible healthcare system, socio-economic and ethnic disparities in childhood cancer survival exist. Findings should inform where resources should be directed to provide all children with an equitable survival outcome following a cancer diagnosis.

Age-period-cohort modelling of type 1 diabetes incidence rates among children included in the EURODIAB 25-year follow-up study.

AIMS: Specific patterns in incidence may reveal environmental explanations for type 1 diabetes incidence. We aimed to study type 1 diabetes incidence in European childhood populations to assess whether an increase could be attributed to either period or cohort effects. METHODS: Nineteen EURODIAB centres provided single year incidence data for ages 0-14 in the 25-year period 1989-2013. Case counts and person years were classified by age, period and cohort (APC) in 1-year classes. APC Poisson regression models of rates were fitted using restricted cubic splines for age, period and cohort per centre and sex. Joint models were fitted for all centres and sexes, to find a parsimonious model. RESULTS: A total of 57,487 cases were included. In ten and seven of the 19 centres the APC models showed evidence of nonlinear cohort effects or period effects, respectively, in one or both sexes and indications of sex-specific age effects. Models showed a positive linear increase ranging from approximately 0.6 to 6.6%/year. Centres with low incidence rates showed the highest overall increase. A final joint model showed incidence peak at age 11.6 and 12.6 for girls and boys, respectively, and the rate-ratio was according to sex below 1 in ages 5-12. CONCLUSION: There was reasonable evidence for similar age-specific type 1 diabetes incidence rates across the EURODIAB population and peaks at a younger age for girls than boys. Cohort effects showed nonlinearity but varied between centres and the model did not contribute convincingly to identification of environmental causes of the increase.

HbA1c values and hospital admissions in children and adolescents receiving continuous subcutaneous insulin infusion therapy.

AIMS: To assess HbA1c values and hospitalization rates before, during and after continuous subcutaneous insulin infusion (CSII) therapy. METHODS: Demographic and hospitalization data were extracted from 161 individuals with Type 1 diabetes who received continuous subcutaneous insulin infusion (CSII) therapy between 2002 and 2013 at the Leeds Children and Young People's Diabetes Service for those aged < 20 years. The median (range) age at CSII start was 11.9 (1.1-17.6) years. The median (range) follow-up time was 2.3 (0-8.1) years. Random intercept models were used to compare HbA1c values before and during CSII initiation (and after CSII for those who discontinued it). Hospitalization rates were calculated for diabetic ketoacidosis and severe hypoglycaemia. RESULTS: The mean HbA1c concentration decreased by 7 mmol/mol [95% CI 6-8; 0.6% (95% CI 0.5-0.7%)]. For the discontinued group (n=30), mean HbA1c decreased by 5 mmol/mol [95% CI 2-8; 0.4% (95% CI 0.2-0.7%)]. HbA1c returned to pre-CSII start levels at the end of this therapy. Diabetic ketoacidosis admissions increased threefold during CSII compared with before CSII start [2.2 per 100 person-years (95% CI 1.3 to 3.6) vs 7.4 per 100 person-years (95% CI 5.1 to 10.8)] and was highest during the first year of CSII. No difference in severe hypoglycaemia incidence rate was found during CSII compared with the pre-CSII period. CONCLUSIONS: Despite significant reductions in HbA1c levels for individuals treated with CSII, improvements are needed to reduce diabetic ketoacidosis hospitalizations for those new to the therapy.

Israeli and British women's wellbeing and eating behaviours in pregnancy and postpartum.

OBJECTIVES: The study had two main objectives: (a) track changes in self-esteem, eating behaviours and body satisfaction from early pregnancy to 24 months postpartum and (b) to compare changes by context (Israel vs. UK) and maternal body mass index (BMI). BACKGROUND: High maternal BMI is associated with negative body image and restrained eating, which are experienced differently across cultures. METHODS: 156 pregnant women were recruited from Israel and the UK. Seventy-three women were followed up every six months from early postpartum and until 24 months following birth. Women completed questionnaires assessing self-esteem (RSEQ), body image (BIS/BIDQ) and eating behaviours (DEBQ) and self-reported weights and heights so that BMI could be calculated. RESULTS: Women with higher BMI had higher levels of self-esteem and were less satisfied with their body. Healthy-weight women were more likely to lose all of their retained pregnancy weight compared to overweight and obese women. Self-esteem, body image and eating behaviours remained stable from pregnancy until 24 months postpartum. No significant differences were found for any measure by context. CONCLUSION: BMI was the strongest predictor of self-esteem and body dissatisfaction and a higher BMI predicted less weight loss postpartum.

Mortality and acute complications in children and young adults diagnosed with Type 1 diabetes in Yorkshire, UK: a cohort study.

AIMS: To examine all-cause and cause-specific mortality in a population-based cohort of people with early and late onset of Type 1 diabetes. METHODS: The Yorkshire Register of Diabetes in Children and Young People includes individuals with early (0-14 years) and late (15-29 years) Type 1 diabetes onset, diagnosed between 1978 and 2013. This register was linked to death certification data from the Office for National Statistics to calculate standardized mortality ratios, cumulative mortality curves using Kaplan-Meier survival estimates, and Cox regression modelling. Ethnicity was derived using Onomap. Deprivation status was classified using the Townsend index. The underlying cause of death in each case was clinically verified. RESULTS: There were 229 deaths in 5498 individuals with 100 959 person-years of follow-up. The overall standardized mortality ratio was 4.3 (95% CI 3.8 to 4.9). There were no significant differences in standardized mortality ratios according to age of onset, sex or deprivation status. The standardized mortality ratios were significantly higher for people of white ethnic origin [8.1 (95% CI 6.9 to 9.4)] than for those of South-Asian ethnic origin [3.4 (95% CI 1.7 to 6.4)]. The mortality risk was lower in those diagnosed in later years (2002 to 2013 for the early-onset and 2006 to 2013 for the late-onset group) compared with earlier years (1991 to 1997 for the early-onset and 1991 to 1997 for the late-onset group) for both onset groups [hazard ratio 0.13 (95% CI 0.05 to 0.33) vs 0.24 (95% CI 0.07 to 0.81)]. Mortality risk improved over time for chronic complications in the early-onset group only, but there was no improvement in either onset group with regard to acute complications. CONCLUSIONS: An excess of deaths in the population with Type 1 diabetes remains. Although the all-cause mortality risk has fallen over time, no improvement has been found in the mortality risk associated with acute complications.

Comparison of quadrant-specific breast cancer incidence trends in the United States and England between 1975 and 2013.

BACKGROUND: UK breast cancer incidence rates suggest that upper outer quadrant (UOQ) cancers have risen disproportionately compared with other areas over time. We aimed to provide a comparison of the trend in quadrant-specific breast cancer incidence between the United States (US) and England, and determine whether a disproportionate UOQ increase is present. METHODS: Surveillance Epidemiology and End Results (SEER) cancer registry data were obtained on 630,007 female breast cancers from 1975 to 2013. English cancer registry data were obtained on 1,121,134 female breast cancers from 1979 to 2013. Temporal incidence changes were analysed using negative binomial regression. Interaction terms determined whether incidence changes were similar between sites. RESULTS: English breast cancer incidence in the UOQ rose significantly from 13% to 28% from 1979 to 2013 whereas no significant increase was observed among SEER data. The significant interaction between quadrant and year of diagnosis (p<0.001) in both SEER and English data indicates that breast cancer incidence in each quadrant changed at a different rate. Incidence in the UOQ rose disproportionately compared to the nipple (SEER IRR=0.81, p<0.001; England IRR=0.78, p<0.001) and axillary tail (SEER IRR=0.87, p=0.018; England IRR=0.69, p<0.001) in both SEER and England. In addition, incidence rose disproportionately in the UOQ compared to non-site-specific tumours in England (Overlapping lesions IRR=0.81, p=0.002; NOS IRR=0.78, p<0.001). The proportion of non-site-specific tumours was substantially higher in England than SEER throughout the study period (62% in England; 39% in SEER). CONCLUSIONS: Breast cancer incidence in the UOQ increased disproportionately compared to non-site-specific tumours in England but not in SEER, likely due to the decrease in non-site-specific tumours observed in England over time. There may be real differences in incidence between the two countries, possibly due to differences in aetiology, but is much more likely to be an artefact of changing data collection methods and improvements in site coding in either country.

Population mixing and incidence of cancers in adolescents and young adults between 1990 and 2013 in Yorkshire, UK.

PURPOSE: Epidemiological evidence suggests a role for an infectious etiology for cancers in teenagers and young adults (TYAs). We investigated this by describing associations between infection transmission using the population mixing (PM) proxy and incidence of cancers in TYAs in Yorkshire, UK. METHODS: We extracted cancer cases from the Yorkshire Specialist Register of Cancer in Children and Young People from 1990 to 2013 (n = 1929). Using multivariable Poisson regression models (adjusting for effects of deprivation and population density), we investigated whether PM was associated with cancer incidence. We included population mixing-population density interaction terms to examine for differences in effects of PM in urban and rural populations. RESULTS: Nonsignificant IRRs were observed for leukemias (IRR 1.20, 95% CI 0.91-1.59), lymphomas (IRR 1.09, 95% CI 0.90-1.32), central nervous system tumors (IRR 1.06, 95% CI 0.80-1.40) and germ cell tumors (IRR 1.14, 95% CI 0.92-1.41). The association between PM and cancer incidence did not vary in urban and rural areas. CONCLUSIONS: Study results suggest PM is not associated with incidence of cancers among TYAs. This effect does not differ between rural and urban settings.

Incidence and survival of children and young people with central nervous system embryonal tumours in the North of England, 1990-2013.

BACKGROUND: Medulloblastoma and primitive neuroectodermal tumours (PNET) are the most common central nervous system (CNS) embryonal tumours diagnosed in childhood. Survival outcomes are worse for children diagnosed with CNS PNET compared to medulloblastoma. Less is known about survival outcomes in teenagers and young adults (TYA). METHODS: Data were extracted from two population-based cancer registries of children and young people (0-24 years) in the north of England for all diagnoses of medulloblastoma and CNS PNET between 1990 and 2013. Incidence and survival trends were analysed using Poisson and Cox regression. RESULTS: Between 1990 and 2013, 197 medulloblastomas and 58 CNS PNET were diagnosed, age-standardised incidence rates of 3.8 and 1.5 per million, respectively. Medulloblastoma incidence decreased over time while there was no significant change in trend for CNS PNET. The overall 5-year survival rate was 54%. The risk of death was 2.4 times higher (95% confidence interval [CI] 1.6, 3.7) for patients with CNS PNET compared to medulloblastoma, after adjustment for patient characteristics. There was a 39% reduction (95% CI 0.43, 0.87) in the risk of death for patients diagnosed between 2000 and 2013 compared to 1990-1999. Risk of death did not differ for TYA (15-24 years) compared to children aged 5-9 years. CONCLUSIONS: Medulloblastoma incidence decreased over time and differences in survival between medulloblastoma and PNET emerged within the first-year post diagnosis leading to poorer outcomes for children and young adults diagnosed with PNET; however, a significant improvement in survival over time was observed.

Trends in survival for teenagers and young adults with cancer in the UK 1992-2006.

BACKGROUND: Although relatively rare, cancer in teenagers and young adults (TYA) is the most common disease-related cause of death and makes a major contribution to years of life lost in this age group. There is a growing awareness of the distinctive needs of this age group and drive for greater understanding of how outcomes can be improved. We present here the latest TYA survival trends data for the United Kingdom (UK). METHODS: Using national cancer registry data, we calculated five-year relative survival for all 15-24 year olds diagnosed with cancer or a borderline/benign CNS tumour in the UK during the periods 1992-1996, 1997-2001 and 2002-2006. We analysed trends in survival for all cancers combined and for eighteen specified groups that together represent the majority of TYA cancers. We compared our data with published data for Europe, North America and Australia. RESULTS: Five-year survival for all cancers combined increased from 75.5% in 1992-1996 to 82.2% in 2002-2006 (P<0.001). Statistically significant improvements were seen for all disease groups except osteosarcoma, rhabdomyosarcoma, non-gonadal and ovarian germ cell tumours and ovarian and thyroid carcinomas. During the earliest time period, females had significantly better survival than males for five of the twelve non-gender-specific disease groups. By the latest period, only melanomas and non-rhabdomyosarcoma soft tissue sarcomas had differential survival by gender. Survival in the UK for the most recent period was generally similar to other comparable countries. CONCLUSION: Five-year survival has improved considerably in the UK for most cancer types. For some disease groups, there has been little progress, either because survival already approaches 100% (e.g. thyroid carcinomas) or, more worryingly for some cancers with poor outcomes, because they remain resistant to existing therapy (e.g. rhabdomyosarcoma). In addition, for a number of specific cancer types and for cancer as a whole males continue to have worse outcomes than females.

"It's like giving him a piece of me.": Exploring UK and Israeli women's accounts of motherhood and feeding.

OBJECTIVE: The present study explored how Israeli and UK mothers integrate feeding into their conceptualisations of mothering 2-6 months post-partum. BACKGROUND: The nature and importance of motherhood is subject to differential contextual, cultural, political and historical influences. We set out to compare experiences of motherhood and feeding between these two countries using a qualitative approach. METHODS: Forty one women (mean age 36.4 ± 2.7 years) from Israel and the UK, mostly married or in a committed relationship were interviewed about their experience of pregnancy, motherhood and feeding. Data were analysed thematically. RESULTS: The experience of motherhood in the early postnatal period was dominated, for all mothers, by the experience of breastfeeding and clustered around three representations of mothering, namely; 1) a devoted mother who ignores her own needs; 2) a mother who is available for her infant but acknowledges her needs as well; and 3) a struggling mother for whom motherhood is a burden. Such representations existed within both cultural groups and sometimes coexisted within the same mothers. UK women described more struggles within motherhood whereas a tendency towards idealising motherhood was observed for Israeli women. CONCLUSION: There are similarities in the ways that UK and Israeli women experienced motherhood and feeding. Where family life is strongly emphasized, mothers reported extremes of idealism and burden and associated an "ideal" mother with a breastfeeding mother. Where motherhood is represented as just one of many roles women take up, they are more likely to represent a "good enough" approach to mothering. Understanding the experience of motherhood and feeding in different cultural settings is important to provide the context for postnatal care specifically where mothers are reluctant to share problems or difficulties encountered.

Breast is best: Positive mealtime interactions in breastfeeding mothers from Israel and the United Kingdom.

We examined mealtime interactions to assess whether they varied according to maternal body mass index, country and mode of feeding in 41 Israeli and UK mother-infant dyads. Feeding behaviours were coded using the Simple Feeding Element Scale. Significantly, more UK mothers breastfed during the filmed meal compared to Israeli mothers. Mealtime interactions did not vary according to maternal body mass index or country. Women who breastfed (as opposed to those who bottle fed or fed solids) provided fewer distractions during the meal, a more ideal feeding environment and fed more responsively.

Cardiovascular sequelae in long-term survivors of young peoples' cancer: a linked cohort study.

BACKGROUND: We aimed to define the incidence and risk of cardiovascular late effects (LEs) identified from inpatient hospital episode statistics (HES) among long-term survivors of cancer in young people by age at diagnosis (0-14 and 15-29 years). METHODS: Records from the Yorkshire Specialist Register of Cancer in Children and Young People (1991-2006) were linked to inpatient HES data (1996-2011) to assess rates of cardiovascular LEs. Rates were compared with the general population in Yorkshire using age-sex-matched HES records for the entire region. RESULTS: Of 3247 survivors of cancer, 3.6% had at least one cardiovascular LE. Overall, cardiovascular hospitalisations for the childhood cohort were threefold higher compared with the general population, but did not differ for young adults. For young adults, increased rates were limited to pericardial disease, cardiomyopathy and heart failure, pulmonary heart disease, hypertension and conduction disorders. CONCLUSIONS: Survivors of childhood and young adult cancer remain at increased risk of cardiovascular LEs compared with the general population.

Does referral to specialist paediatric palliative care services reduce hospital admissions in oncology patients at the end of life?

BACKGROUND: Despite advances in the treatment of childhood cancer, some children continue to die from their disease. This study aimed to assess the impact of specialist paediatric palliative care services (SPPCSs) on the number of hospital admissions in children who subsequently died from cancer in Yorkshire, UK. METHODS: An extract of patients aged 0-19 years from the Yorkshire Specialist Register of Cancer in Children and Young People (YSRCCYP) diagnosed from 1990 to 2009 were linked to inpatient hospital episodes data and a SPPCS database. Deaths were included if they occurred before 31 August 2011. Differences in hospital admission patterns were assessed using negative binomial regression and presented as incidence rate ratios (IRRs). RESULTS: Of 2508 children on the YSRCCYP, 657 (26%) had died by the censoring date. A total of 211 children had been referred to the local SPPCS, of whom 182 (86%) had subsequently died. Referral to SPPCS was associated with a significant reduction in the rate of planned hospital admissions (IRR=0.60, 95% CI 0.43-0.85). Central nervous system tumours showed significant decreases for all planned and emergency admissions compared with all other diagnostic groups. CONCLUSION: Referral to SPPCS significantly reduced the number of planned hospital admissions for children and young people with cancer before their death, which are often integral to paediatric oncology treatment regimens. Overall, our findings show that SPPCS have a role in reducing hospital admissions during end of life care of paediatric cancer patients with potential personal, social and economic benefits.

The impact of a managed transition of care upon psychosocial characteristics and patient satisfaction in a cohort of adult survivors of childhood cancer.

OBJECTIVE: Many adult survivors of childhood cancer receive care in paediatric departments, despite national policy to transition their care to adult services. When long-term follow-up care for survivors of childhood cancer in our region moved from a paediatric to an adult environment in 2009, we prospectively assessed the impact of this change on patient satisfaction. METHODS: Questionnaire data were collected in paediatric and adult clinical environments regarding the level of satisfaction with care and potential mediators: quality of life, psychological health and social difficulties. Predictors of satisfaction and optimum longitudinal risk-based care were described using path analysis and compared with previously described models. RESULTS: There was no significant difference in satisfaction between the paediatric and adult settings. Short waiting times and increased understanding of the purpose of follow-up were significantly associated with increased satisfaction. Those with a higher perception of health problems and those that were older were more likely to not attend all of their clinic appointments. CONCLUSIONS: Within our service, transition to adult care did not impact significantly upon patient satisfaction. Shorter waits and knowing why participants were attending the clinic increased satisfaction. Joint working between adult and paediatric cancer professionals enabled adult survivors of childhood cancer to receive highly satisfactory care in adult services.

Changes in the patterns of care of central nervous system tumours among 16-24 year olds and the effect on survival in Yorkshire between 1990 and 2009.

AIM: There is a paucity of work documenting the influence of patterns of care on survival for teenagers and young adults with primary central nervous system tumours. Therefore, the aim of this study was to undertake a detailed assessment examining any changes in the patterns of care over time and how these related to survival outcomes for 16-24 year olds diagnosed with a primary central nervous system tumour between 1990 and 2009. MATERIALS AND METHODS: We used high-quality data from one population-based cancer registry in Yorkshire, UK to describe primary central nervous system tumours in teenagers and young adults (16-24 years) diagnosed between 1990 and 2009. The Birch classification scheme was used to identify differences by tumour subgroup. Incidence, patterns of care and survival trends were described using Poisson and Cox regression. RESULTS: There were 163 cases comprising 98 astrocytomas, 17 'other gliomas', 14 ependymomas, 11 medulloblastomas and 23 'other intracranial and intraspinal neoplasms' yielding an overall incidence of 18.1 million person-years. Care varied significantly over time and by principal treatment centre (Leeds 77%, Hull 23%), co-ordinating specialty (neurosurgery 53%, clinical oncology 22%, paediatrics 17%, other adult services 8%) and treatment received. Cox regression showed no significant difference in survival by age, gender, treatment centre, level of deprivation, year of diagnosis or co-ordinating specialty, but a significant difference by tumour grade and diagnostic group. Survival improved for all diagnostic groups except astrocytoma, although only the medulloblastoma group showed a significant change over time. CONCLUSION: The lack of any significant improvement in survival over time in most diagnostic groups warrants further investigation and provides justification for a more collaborative regional approach to the care of central nervous system tumours, perhaps through the development of regional guidelines for this unique population. More detailed analysis of relapse patterns and prediagnostic symptoms would also be informative for this cohort.

Survival trends of cancer amongst the south Asian and non-south Asian population under 30 years of age in Yorkshire, UK.

INTRODUCTION: Several studies have shown differences in survival trends between ethnic groups across adults with cancer in the UK. It is unclear whether these differences exist exclusively in the older adult population or whether they begin to emerge in children and young adults. METHODS: Subjects (n=3534) diagnosed with cancer under 30 years of age in Yorkshire between 1990 and 2005 were analysed. Differences in survival rates for diagnostic subgroups were estimated by ethnic group (south Asian or not) using Kaplan-Meier estimation and Cox regression. RESULTS: When compared to non-south Asians (all other ethnic groups excluding south Asians) a significant increased risk of death was seen for south Asians with leukaemia (hazard ratio (HR)=1.75; 95% confidence interval (CI)=1.11-2.76) and lymphoma (HR=2.05; 95% CI=1.09-3.87), whereas south Asians with solid tumours other than central nervous system tumours had a significantly reduced risk of death(HR=0.50; 95% CI=0.28-0.89). This was independent of socioeconomic deprivation. CONCLUSION: We found evidence of poorer survival outcomes for south Asians compared to non-south Asian children and young adults with leukaemia and lymphoma, but better outcomes for south Asian children and young adults with other solid tumours. This needs to be explained, and carefully addressed in the on-going development of cancer services.

Incidence rate trends in childhood type 1 diabetes in Yorkshire, UK 1978-2007: effects of deprivation and age at diagnosis in the South Asian and non-South Asian populations.

AIMS: Incidence of Type 1 diabetes in children is increasing worldwide. Earlier studies suggest that UK south Asian immigrants develop similar rates to the overall UK population, although incidence is lower in their country of origin. This study examines incidence rate trends of childhood Type 1 diabetes in Yorkshire 1978-2007, focusing on differences between south Asians and non-south Asians. METHODS: Data from the population-based Yorkshire Register of Diabetes in Children and Young People were used to estimate incidence (per 100,000 childhood population < 15 years per year) of Type 1 diabetes, stratified by sex, age and ethnicity validated using two name-recognition programs. Age-sex standardized rates were calculated for 1978-2007 and assessed by ethnic-group and deprivation for 1990-2007. We used Poisson regression to assess incidence trends and predict rates until 2020. RESULTS: From 1978-2007, 3912 children were diagnosed. Overall incidence was 18.1 per 100,000 childhood population (< 15 years) per year (95% CI17.6-18.7) and increased significantly over time: 13.2 (1978-1987) to 17.3 (1988-1997) to 24.2 (1998-2007). Average annual percentage change was 2.8% (2.5-3.2). Incidence for non-south Asians (21.5; 20.7-22.4) was significantly higher than for south Asians (14.7; 12.4-17.1). Average annual percentage change increased significantly over 18 years (1990-2007) in non-south Asians (3.4%; 2.7-4.2) compared with a non-significant rise of 1.5% (-1.5 to 4.6) in south Asians. Deprivation score did not affect overall incidence. CONCLUSIONS: Type 1 diabetes incidence rose almost uniformly for non-south Asians, but not for south Asians, contrary to previous studies. Overall rates are predicted to rise by 52% from 2007 to 2020 to 39.0 per 100,000 per year.

Cancer incidence among the south Asian and non-south Asian population under 30 years of age in Yorkshire, UK.

BACKGROUND: Few studies have examined epidemiological differences between ethnic groups for children and young adults with cancer. METHODS: Subjects aged 0-29 years, diagnosed between 1990 and 2005 in the former Yorkshire Regional Health Authority, were included in the analysis. Ethnicity (south Asian or not) was assigned using name analysis program and Hospital Episode Statistics data. Differences in incidence (per 1,000,000 person-years) rates and trends were analysed using joinpoint and Poisson regression analysis. RESULTS: Overall cancer incidence was similar for south Asians (12.1, 95% CI: 10.7-13.5; n=275) and non-south Asians (12.6, 95% CI: 12.2-13.1; n=3259). Annual incidence rates increased significantly by 1.9% per year on average (95% CI: 1.2-2.6%), especially for south Asians (7.0%; 95% CI: 4.2-9.9%). CONCLUSION: If present trends continue, the higher rate of increase seen among south Asians aged 0-29 years in Yorkshire will result in three times higher cancer incidence than non-south Asians by 2020.

Weighing and measuring primary school children: evaluation of the TRENDS model for implementation of Department of Health guidelines.

BACKGROUND: The UK Department of Health for England and Wales has issued guidance to all local Primary Care Trusts (PCTs), who have responsibility for school nursing services, for the annual weighing and measuring of all children on entry to primary school and in Year 6 (age 5 and 11 years respectively), known as the National Child Measurement Programme. The guidance places the responsibility for implementation and funding of this scheme onto the PCTs. METHOD: This paper describes the conduct and evaluation of the 2006 monitoring exercise in a 10% sample of Leeds primary schools. RESULTS: The evaluation showed that the exercise can be carried out with little disruption in schools and minimal distress for children. CONCLUSIONS: Recommendations include: adequate staff training in measuring children, along with anticipation of the issues and problems they may encounter and best practice for dealing with them. A good working relationship must be established between the team and school before the measuring day. Schools need to ensure the availability of suitable accommodation and a screen to maintain privacy.

Where possible, children should not be lined up, but seen individually. This is considered essential for the older Year 6 children.
