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.

Symptoms of depression and anxiety, and change in body mass index from adolescence to adulthood: results from a British birth cohort

BACKGROUND

Depression and anxiety have been shown to be associated with obesity and underweight, but little is known about how the relationship varies across the life course, from adolescence through adulthood. We aimed to investigate the association between adolescent- and adult-onset affective symptoms and body mass index (BMI) change from age 15 to 53 years.

METHOD

We used data from a British birth cohort born in 1946 and followed up ever since. The relationship between affective symptom profiles, distinguishing adolescent-onset and adult-onset symptoms, and BMI change from adolescence to age 53 years was investigated using multilevel models.

RESULTS

Women with adolescent-onset symptoms had lower mean BMI at age 15 years, faster rates of increase across adulthood, and higher BMI at age 53 years than those with no symptoms. Men with adolescent-onset symptoms had lower BMI at all ages from 15 to 53 years. The BMI trajectories of men and women with adult-onset symptoms did not differ from those with absence of symptoms at all ages.

CONCLUSIONS

The relationship between affective symptoms and change in BMI varies by sex and age at onset of symptoms. Adolescence may be an important period for the development of the association between affective symptoms and weight gain in girls. Intervention to prevent increases in BMI across adult life in women with adolescent-onset symptoms, even if they are not overweight at this age, should be considered.

Associations between IQ and common mental disorders: the 2000 British National Survey of Psychiatric Morbidity

BACKGROUND

Associations have been described between lower IQ and serious mental illness. Associations between common mental disorders (CMDs) and IQ have received little research. The objective of this study was to investigate the association between verbal IQ and CMD symptoms and diagnoses, and to investigate the role of potential mediating and confounding factors.

METHOD

Data were analysed from a British national survey with an analysed sample of 8054 people aged 16-74 years. Associations between verbal IQ (NART) and mental symptoms/disorders (CIS-R) were analysed with covariates including education, social class, income, debt, problem drinking, life events, physical health and relationship quality.

RESULTS

CMD was associated with lower IQ. This association was stronger for depressive disorder/symptoms than for generalised anxiety disorder/symptoms. The most important covariates were education, social class, income and relationship quality.

CONCLUSION

The association between lower IQ and CMD is partly accounted for by adverse social/socioeconomic conditions. Stronger associations for depression than anxiety may indicate an effect of IQ on the way mental distress is communicated.

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.

Parental practices predict psychological well-being in midlife: life-course associations among women in the 1946 British birth cohort

BACKGROUND

Certain parenting styles are influential in the emergence of later mental health problems, but less is known about the relationship between parenting style and later psychological well-being. Our aim was to examine the association between well-being in midlife and parental behaviour during childhood and adolescence, and the role of personality as a possible mediator of this relationship.

METHOD

Data from 984 women in the 1946 British birth cohort study were analysed using structural equation modelling. Psychological well-being was assessed at age 52 years using Ryff's scales of psychological well-being. Parenting practices were recollected at age 43 years using the Parental Bonding Instrument. Extraversion and neuroticism were assessed at age 26 years using the Maudsley Personality Inventory.

RESULTS

In this sample, three parenting style factors were identified: care; non-engagement; control. Higher levels of parental care were associated with higher psychological well-being, while higher parental non-engagement or control were associated with lower levels of psychological well-being. The effects of care and non-engagement were largely mediated by the offspring's personality, whereas control had direct effects on psychological well-being. The psychological well-being of adult women was at least as strongly linked to the parenting style of their fathers as to that of their mothers, particularly in relation to the adverse effects of non-engagement and control.

CONCLUSIONS

This study used a prospective longitudinal design to examine the effects of parenting practices on psychological well-being in midlife. The effects of parenting, both positive and negative, persisted well into mid-adulthood.

Results of a quantitative survey to explore both perceptions of the purposes of follow-up and preferences for methods of follow-up delivery among service users, primary care practitioners and specialist clinicians after cancer treatment

AIMS

To ascertain perceptions of reasons for follow-up after cancer treatment among service users (patients and carers), primary care practitioners and specialist clinicians (doctors and specialist nurses) and to identify levels of preference for different models of follow-up and the effect of an individual's experience on preferred models.

MATERIALS AND METHODS

A national survey designed to meet the needs of each key respondent group was carried out after a structured literature review, an extensive consultation process and a pilot scheme. Respondents were asked to assess their degree of preference for 10 pre-selected indications for follow-up. Eight models of follow-up were also identified and respondents were asked to state their experience and preference for each type. The questionnaire was distributed nationally via the 34 cancer networks in England and was available both online and in hard copy (postal). The uptake for the electronic format was in the main by primary care practitioners and specialist clinicians. Service users preferred the paper (postal) format. The survey was also publicised through the primary care and patient partnership forums at a Cancer Network Development event.

RESULTS

In total, 2928 responses were received, comprising service users (21% of the sample), primary care practitioners (32%) and specialist clinicians (47%). Eighty-six per cent of responses were received from the 10 strategic health authorities in England, with the remaining 14% from Scotland, Wales and The Isle of Man. The responses from Scotland, Wales and the Isle of Man generally occurred where they interfaced with English cancer networks or had been engaged through word of mouth by colleagues. Among all respondents the main aims of cancer follow-up were considered to be: (1) to monitor for early complications after treatment; (2) to detect recurrences early; (3) to detect late effects of treatment. The most commonly experienced method of follow-up among all respondent groups was outpatient review with a doctor. This was considered to be the most preferred follow-up option among service users (86%). The least preferred option among service users was postal follow-up (32%). Primary care practitioners and specialist clinicians were more likely than service users to have experienced alternative methods of follow-up, such as telephone follow-up, self-triggered referral and non-specialist follow-up. These models were highly rated by those who had experience of them.

CONCLUSIONS

There was a reasonable level of consensus between service users, primary care practitioners and specialist clinicians as to the reasons for follow-up. Service users seemed to have higher expectations of follow-up, particularly in relation to detecting recurrences early. As respondents were more likely to prefer a method of follow-up delivery that they had experienced than one they had not; there could be resistance to change from established methods to new methods without adequate explanation. This suggests that the communication of new methods could be critical to their successful introduction.
